Description

This application is a continuation-in-part of PCT / AU02 / 01105, filed on August 7, 2002, with the US as the designated country, and is a patent application US CIP 10/781 filed on February 17, 2004. , 321 is a continuation-in-part application based on US CIP 10 / 789,961 filed on February 27, 2004, the contents of all of which are incorporated herein by reference. It is supposed to be.

The present invention relates to a contact lens packaging container, and more particularly to an economically improved type of contact lens package that meets the criteria for lens packaging containers including disposability that requires consideration of sterility and environmental issues. Another aspect of the present invention is a package that provides a method for positioning and providing a lens in a fixed orientation and a method for removing the lens from the package, and for improved distribution, travel suitability and / or distribution. And package configured.

Disposable soft contact lenses are usually housed in disposable packages. Because the packaging container increases the overall cost of the lens, it must be as economical as possible without compromising the standards essential to the packaging container. Conventional blister packages for disposable lenses (2-week type and 1-day type) (FIGS. 1 to 3) are made of a polypropylene lens container (hereinafter referred to as “multilayer film” of polyethylene, aluminum, adhesive and polypropylene). Boat). Boats are usually injection molded plastic, have high rigidity and slight elastic flexibility, and include preformed recesses. The boat is filled with a solution suitable for storage, preferably saline, in which one lens is stored. Blister packs are pressurized and finally sterilized using steam. These blister packs are given to the patient as individual packs are placed in a box (FIGS. 4 and 5) or a plurality are connected to the strip.

The purpose of the sale is to provide the patient with a contact lens in a beautiful-looking package that meets both sterility and stability legal requirements, allows the lens to be removed safely and easily. The packaging container is used only once and is discarded after the lens is removed. This greatly affects the combined cost of the lens and the package. In order to keep the overall price of the lens for the patient, the cost of the packaging container must be kept to a minimum. Furthermore, the discardability of the lens package must meet environmental protection standards.

Contact lenses must be kept wet in the package. The package must be well sealed and the moisture contained through the boat or laminate layer is minimized to prevent the lens contained in the package from drying out to maximize shelf life. There must be. When used, the laminate material is removed by peeling from the flange formed on the “boat” to reveal the lens immersed in the preservative solution.

Various types of contact lens packages are known in the prior art, particularly disposable contact lens packages including preformed blister packs. Where the prior art typically shows, conventions in the contact lens industry have defined preformed rigid packages to prevent damage to the lens due to load. An example of a typical known blister package is:
US Pat. No. 5,704,468, US Pat. No. 4,392,569, US Pat. No. 5620088
US Pat. No. 4,691,820, US Pat. No. 5,823,327, US Pat. No. 5,830,530
85, European Patent Publication EP1092645A1, and European Patent Publication EP1092645. The problem with many blister packages is that there is a high peak in the force required to peel the film layer from the blister, and then a sudden decrease in the amount of force required to open the main part of the seal. Is to continue. This can result in a non-smooth movement to open the blister and spill the contents.

Flexible retort packages are known except for use with contact lenses. One such package is disclosed in US Pat. No. 4,769,261. This patent discloses a sealing layer used in large size retort bags composed of an ABA film structure, each of which consists of a mixture of a small amount of elastomer and a large amount of polyolefin, and B layer is a large amount of elastomer. And a small amount of polyolefin. Retort bags are made of ABA film structure because the sealing layer exhibits improved strength against impact. Japanese Patent No. 4769261 does not describe the use of a retort package for housing a contact lens.

European Patent Publication EP 0129388 describes a pouch formed by sealingly engaging a single optically transparent film to contain a contact lens and a hydration solution. However, this teaching is aimed at maintaining the contact lens in a natural state so that optical measurements can be made without opening the container. In another aspect of this teaching, the sachet has a holder or support therein to secure the lens so that the radial portion of the curved back surface is optically measured. It is therefore clear that the European patent publication EP 0129388 is aimed at maintaining the contact lens in an equilibrium or natural state.

Similarly, JP-A-6-258603 describes a resin film pack for accommodating a contact lens. The package is formed of a suitable resin material, with 3 of the 4 sides sealed, leaving the 4th side unsealed for the contact lens and storage solution. Once the lens and solution are placed in the package, its fourth side is sealed by heat treatment. There is no way to open the package. Since the contact lens is arranged in the package before the formation from the opening end portion thereof, no means is taken to make the contact lens have a convenient orientation for the user.

Accordingly, the prior art contact lens package has several disadvantages including the following.
1. The package uses two types of materials, one of which is preformed and increases manufacturing costs, making it relatively expensive as a daily disposable package. Consumers show resistance to packages that cause the cost associated with the lens to increase. This will be a major problem for daily disposable market growth and market competition.

2. Prior art packages are traditionally manufactured from two completely different materials. One is used for the boat that houses the lens and the other is used for the cover. This can be a sealing problem with the risk of reduced sterility. Over time, poorly sealed blister packs can cause the moisture content to evaporate and render the pack useless. Defect correction will involve the recall of potentially defective products, and is potentially expensive for manufacturers in terms of financial and reputation for product quality.

3. Lenses that are not good, that is, not sterilized due to imperfect package seals, can cause infections in the patient's eyes, resulting in reduced eye function and associated litigation risks. is there.

4. The size of the packaging container is several times larger than the size of the lens itself, which is a disadvantage for the concept of a disposable lens. Because it is a component of a polypropylene blister, the individual packages are slightly thicker than the overall thickness of the lens, so they do not look like a disposable and are conveniently stacked due to their shape and size. I can't. If the consumer travels, you will find that the lens is a bulky item.

5. The traditional approach to lens packaging has been to maintain the original shape of the lens in the package. This traditional approach places restrictions on the package structure.

6. Further disadvantages can occur with retorted packages taught in the prior art. First, the retort package is generally opened by tearing off the end of the package rather than peeling off the sealed portion. This clearly raises the risk of breaking the lens. Secondly, removing the contact lens from an open retort package means whether to place the finger in the package to remove the lens (which can cause damage over time) or to move the contents of the container into the hand. I need. Third, there is no lens placement in the package such that contact lens placement helps the patient's convenience.

There has long been a need in the disposable contact lens industry to provide a disposable contact lens package that is economical, free of space, and convenient without compromising lens durability, sterility, and utility. At the same time, some of these needs are met by the package for disposable contact lenses disclosed in the prior application PCT / AU02 / 01105 by the applicant published under the international publication number WO 03/016175, Further improvements are devised and disclosed here.

The present invention ameliorates the aforementioned problems by providing a more economical package that replaces the above traditional ones without compromising the legal and medical requirements for contact lens packages. Are trying.

In particular, the present invention relating to this divisional application may cause an infection in the patient's eyes as described in paragraph 0012 above, resulting in a risk of ocular function deterioration and associated litigation, and in paragraph 0015. In consideration of the conventional lens mounting method, which requires either putting a finger in the package or moving the contents of the container into the hand to take out the lens, the moisture retention and cleanliness of the lens when mounting the lens. Provided is a contact lens package that makes it possible to measure the like.

That is, the present invention
At least one sealing member defining a sealed first space and a second space;
Unused contact lenses housed in the first space;
A hydration medium stored in the second space;
The first space is sealed from the second space, and the second space does not contain a contact lens . A contact lens package is provided .

Specifically, the first space and the second space can be detachably connected by a connecting portion formed in the at least one sealing member.

In addition, the second space can be opened before, after, or when the contact lens is taken out from the first space.

A flexible connecting portion formed on the at least one sealing member may be provided between the first space and the second space.

In this case, the flexible connecting portion may be connected to be separable from each other while maintaining the sealing of the first space and the second space.

The at least one sealing member may be a plurality of flexible sealing members that are hermetically connected to each other to form the first and second spaces.

The contact lens package described above has a package of a second package unit connected to the package, and the second package includes:
  At least one sealing member defining a third space and a fourth space;
  Unused contact lenses stored in the third space;
  A second hydration medium stored in the fourth space;
  Have
  The third space may be sealed from the fourth space.

The hydration medium described above can be one of a rewetting liquid, a cleaning liquid, and a preserving liquid .

Specifically, the hydration medium can be saline .

The first hydration medium can be a liquid .

The present invention will be described below with reference to the accompanying drawings. The present invention is shown in particular in FIGS. 21 to 42 and 117, and various forms of contact lens packages to which the present invention is applicable are shown and described in other figures for reference .

When the contact lens package is on a flat surface, the term “depth of the contact lens storage space” refers to the thickness of the opposing wall forming the contact lens holding portion from the height of the entire contact lens holding portion of the package. It means the depth of the contact lens holding part in the contact lens package determined by subtracting the total.

The term “height of the curved outer surface relative to the peripheral edge” means the height of the entire contact lens placed without being bent on a flat surface.

Stated that the contact lens is in its “equilibrium” state means that the contact lens is not subject to any external force limitations that affect its shape or height.

As used herein, the term homogeneous refers to a package wall formed from a single layer of the same material (ie, not a laminate layer). Many of the packages described as consisting of a homogeneous single layer material are also from multi-layer laminate materials that can be formed from suitable plastic combinations or suitable plastic and metal layer combinations as described in this document. Can be configured.

1 and 2, a typical prior art disposable blister contact lens package 1 formed from two parts is shown. The package 1 has a blister pack part 2. The blister pack portion 2 is sealed by a thin film 3 that forms a lid of the package 1, and the thin film can be peeled off to take out the contact lens 4 therein. FIG. 3 shows a state where the thin film 3 is peeled off so that the contact lens 4 of the package of FIG. 2 appears. Typically, the member 2 is a preformed blister pack and has a specially shaped recess 5 which is a recess in which the lens can be placed. The member 2 is typically injection molded and the package is complete with a sealing member 3 that creates a sterile sealed condition by calling the flange 6. The contact lens 4 is immersed in the storage solution 7 and kept in a water-containing state until it is removed from the pack. Pre-injection molding makes the manufacture of the package expensive, and as a result, contact lenses are inevitably more expensive for the consumer.

FIG. 4 shows a stack configuration for two identical prior art contact lens packages 10 and 11. From FIG. 4 it can be seen that the two packs bite conveniently, but they are thicker than the thickness (depth) of the two packs. Considering that contact lenses are relatively small, ideally the lens package should occupy as little space as possible. Space saving is an important issue because lenses are mass produced. Existing blister packs occupy a disproportionate amount of space compared to the size of the lens, increasing the cost of handling and storage. FIG. 5 shows a state in which a plurality of similar blister packs 12 are stacked as shown in FIG. The conventional idea that lenses can only be stacked in a hard container that separates the lens from an external load results in a bulky and inconvenient lens package that consumes a large amount of raw material.

As mentioned above, the preferred embodiment of the present invention provides a disposable package having contact lenses therein. The package has a depth of contact lens housing space that is shallower than the height of the curved outer surface relative to the periphery of the contact lens when the contact lens is in a balanced configuration. In some embodiments, two flat sheet materials are used that are hermetically engaged with each other or hermetically engaged with a support member therebetween, and the contact lens storage space of the package is used. It clearly shows the feature that the depth is shallower than the height of the curved outer surface relative to the peripheral edge of the contact lens.

In some embodiments of the present invention shown in FIGS. 6-9, the disposable contact lens packages 18 can be stacked such that they are mated together like a stacked spoon. That is, when stacked on top of each other, the convex surface of the first package is placed on the concave surface of the second package. The disposable package 18 of this embodiment has first and second sheets 14 and 15, both of which are curved. Therefore, when the disposable package 18 is sealed, there are concave and convex surfaces, and the contact lens is held between those surfaces. Either the top or bottom surface of the disposable package may be convex or concave, however, in a preferred embodiment, the top side of the package is concave and the bottom of the package surface is convex. This type of disposable contact lens package 18 is referred to as “spooning” throughout this document and is as economical as the size required for secondary packaging in terms of space. Another example of a disposable package that can be stacked in this manner is shown in FIG. This type of disposable package can hold the contact lens somewhat flat, in equilibrium and anywhere parallel to it between its continuums. However, a common feature of the disposable package of this embodiment is that the depth of their contact lens storage space is between 0.1 and 3.0 mm, more preferably between 0.2 and 1.5 mm. Most preferably, it is between 0.2 and 0.5 mm. In this example, the depth of the contact lens storage space of the contact lens package is defined as the depth of the contact lens holding portion in the contact lens package defined by the distance between the opposing walls forming the contact lens holding portion of the package. Will be clearly interpreted to mean. The distance is usually measured at the center of the contact lens holding part. When the package has a concave surface and an opposing surface that is concave in the same direction (eg, FIGS. 6-9 and 165), the “depth of contact lens storage space” indicates that the lens is in a defined position within the package It will be apparent that the distance between the walls of the contact lens package is on a line perpendicular to the center of the lens at the time. The depth of the contact lens storage space is drawn through a line passing through the center of the contact lens in the contact lens package that is perpendicular to the lens surface at the lens center point, and the package wall intersects the drawn line. It can be measured by measuring the distance between the lines. The measured distance is the depth of the contact lens storage space of the contact lens package.

In one embodiment of the disposable package of the present invention shown in FIGS. 6 and 8, the disposable package 18 has a contact lens storage space depth of 0.2 to 0.5 mm and is in a first sealing engagement with each other. Sheet material 14 and second sheet material 15. In this embodiment, one of the two sheets 15 is embossed 16 and has a convex curved surface 19. As shown in FIG. 8, the embossing 16 helps to remove the lens 4 by preventing the lens 4 from adhering to the embossed sheet 15. Therefore, the contact lens 4 can be in the intended direction on the opened disposable package 18. As shown in another embodiment 18a of FIGS. 7 and 9, the embossed surface 16a may instead be on the upper sheet 14a, in this example the bottom sheet 15a is convex. On the other hand, it can also have a concave curved surface 19a. FIG. 9 shows a contact lens package in which the depth of the contact lens storage space is between about 0.2 mm and 0.5 mm. The contact lens of this example adheres to a bottom sheet that has not been embossed.

As shown in FIGS. 10 to 12, the embossing 16 can take various shapes such as an abstract pattern, a lattice pattern, and a logo. Alternatively, in the embodiment of the present invention of FIGS. 13 and 14, disposable packages 18c and 18d are not embossed. The sheets 14 and 15 may be opaque, transparent, or colored with white or light green. If the sheet is colored, one preferred embodiment is that the coloring is done inward toward the contact lens so that the contact lens can be easily seen. Furthermore, the sheets 14, 15 can be printed on. As the printing, for example, symbols (words, diagrams, graphics, etc.), prescriptions, usage, manufacturing information, etc. can be considered. This printing can be on the outside of the package, but more preferably it is arranged in the inward direction (when the package is sealed) towards the contact lens, which makes the contact lens more visible.

In another embodiment shown in FIGS. 15-17 and 19, the disposable package 156 has a support member 20. The support member 20 surrounds the contact lens 4 inside the disposable package 156. The support member 20 may be flexible or rigid. For example, polypropylene (PP), polypropylene copolymer (PPCO), polymethylpentene (TPX), polycarbonate (PC), polysulfone (PSF), polyethylene naphthalate (PEN), a cyclic olefin copolymer (COC), a suitable polymer such as fluorinated ethylene propylene (FEP), or other similar materials. The support member 20 does not change the flat contour of the disposable package 156. Further, the thickness of the support member 20 is set to be shallower than the height of the curved outer surface with respect to the peripheral edge of the contact lens 4 when the disposable package 156 is in a sealed state. The support member 20 may also include a handle 21 (FIG. 15) that aids in moving and opening the disposable package 156. The handle portion 21 may optionally have a cutout 24 to help grasp the disposable package 18, as shown in FIG.

In another embodiment illustrated in FIG. 18, the support member 20 a has a mesh portion 22. The mesh portion 22 serves to further hold the contact lens 4 so that it rests on the mesh portion 22 when the lens is inside the disposable package 157. The network portion 22 is, for example, polypropylene (PP), polypropylene copolymer (PPCO), polymethylpentene (TPX), polycarbonate (PC), polysulfone (PSF), polyethylene naphthalate (PEN), cyclic olefin copolymer. It may be composed of a suitable polymeric material such as (COC), fluorinated ethylene propylene (FEP), or other similar materials.

The disposable package with the support member 20 and the disposable package without the support member 20 can take various shapes. For example, disposable packages may be squares, rectangles, ellipses, circles, teardrops, figure-eights, triangles, combinations thereof, symmetric and asymmetric shapes, and straight rulers and rounded corners. it can. Two alternative contact lens package shapes 158, 159 are shown in FIGS. Other shapes are acceptable as long as they can be adapted to soft contact lenses.

In another embodiment shown in FIGS. 22 to 45, the disposable package can have a first space 34 for contact lenses and a second space 32 for hydration media. This combination can take a variety of shapes, in some of which the second space for the hydration medium is a flat circular shape and is optionally used as a handle. 22 and 28, the second space 32 for the hydration medium may be attached to the first space 34 for the contact lens, and the two spaces are connected portions 31 between the two sheets constituting the disposable package 160. Explain that it can be separated by. The connecting portion 31 can be bent easily. For example, the second space 32 is broken off in FIG. 34 and cut out from the first space 34 in FIGS. 22, 28, 35, and 36. The second space 32 for hydration medium may have a cap 30. The cap 30 can be removed by pulling, twisting or breaking. Further, as shown in the disposable package 161 of FIGS. 24 to 25, the second space 32 may remain connected to the first space 34. The first space 34 and the second space 32 may be opened simultaneously or separately. In one example, the first contact lens space 34 is opened prior to the second hydration medium space 32. In another example, the second hydration medium space 32 may be opened prior to the first contact lens space 34. The first space and the second space may be opened by the same means or different means. The first space and the second space 34, 32 can be opened by peeling the foil cover 26 (FIG. 28) or another cover. Further, the first space 34 can be opened by peeling the foil cover 26, and the second space 32 can be opened by removing the cap 30. 26 and 27, the first space 34 is opened by peeling off the foil cover 26 or another cover, while the second space 32 is shown unattached while attached. Yes.

The cover may be heat treated and sealed to one of a base, a support member, or a sheet forming a disposable package. The heat treatment seal may be made all around the package, or only around the first space containing the contact lens. One of the first and second spaces 34 and 32 may be separated either before or after both are opened. In another example, the second space 32 for hydration medium may be opened by separating the second space 32 from the first space 34, and accordingly the disposable package 162 of FIGS. 29-34. As shown in the examples, an opening or channel 36 appears through which the hydration medium can be discharged. In another embodiment, as shown in FIG. 40, the first and second spaces are opened by peeling the cover 26 of the disposable package 163. In the embodiment shown in FIGS. 37 to 39, the two spaces 32, 34 may be opened by peeling the cover 26 from its end, both of which may be opened simultaneously, or one of them may be sealed while the other is sealed. The space can be opened.

The hydration medium can be any solution suitable for contact lens use. For example, the hydration medium can be a rewetting liquid, a cleaning liquid, or other storage liquid. One example of a suitable hydration medium is saline.

In other embodiments shown in FIGS. 41 and 116-117, one disposable package 164 or 182 can be connected to another identical disposable package 164 or 182. FIG. The connected disposable packages may be in the form of strips 41. The quantity of the disposable packages 164 to be connected can be 1 to 90 or 90 to 180. The connected strips 41 of disposable packages may be rolled up or folded into a zigzag shape. The disposable packages 164 and 182 connected in the form of a strip 41 may have only the first contact lens space 34 or may simultaneously have the second hydration medium space 32. Connection portion 31 and 76 between the single-use package is flexible and is easily rupture. Further, in the embodiment of FIG. 41, a notch 40 for breaking that assists in opening the disposable package 164 is shown.

The disposable package strip 41 or a plurality of the same disposable packages can be used in the type of dispenser in which the next package appears. Another In this embodiment, a plurality of single-use packages 164 and 182, connecting portions 31,76 (FIG. 116, FIG. 117) which is readily fracture are connected to one another via, the single use package 164 is removed One disposable package is taken out at a time so that one of the two comes to the take-out portion. Also, a plurality of identical disposable packages are housed in the dispenser so that when one disposable package 164 is removed, it engages with the next similar disposable package 164 so that the next package 164 can be subsequently removed. There is a way to become.

In the example shown in FIGS. 44 and 67, the disposable package holds the contact lens 4 in a flat state therein and restricts the contact lens from moving while the package is sealed. In FIG. 44, the disposable package 164 prevents the problematic movement of the contact lens 4 that occurs in a typical prior art blister pack 27. As illustrated in FIGS. 46 to 48, the contact lens 4 of the prior art blister pack 27 can be inverted, displaced, attached to the side, or folded in half. However, the disposable package in some embodiments of the present invention holds the contact lens 4 in the same position where the lens was originally placed when the package was sealed. Furthermore, the contact lens 4 is always provided in the expected orientation when the disposable package is opened. This alleviates the need to prepare the lens prior to wearing and reduces the risk of lens damage and contamination of the lens and the wearer's eyes. This also facilitates the wearing of the contact lens to the wearer. In general, the wearer's visual acuity will be somewhat impaired prior to wearing the contact lens, so it is beneficial to know the position of the contact lens even if it cannot be seen when the package is opened.

A salient feature of the preferred disposable package of the present invention is that the contact lens 4 is held flat therein, but the disposable package itself need not be flat. The disposable package may take a variety of forms, but a disposable package that is thinly profiled and is compactly stacked and contained is preferred.

As shown in FIGS. 49A to 51B, there are various structures and forms effective for producing a disposable package. 49A and 49B, the pouch type disposable package 165 is formed of three layers. The two sheet material outer layers 14, 15 are typically aluminum foil and the inner layer is polypropylene or other suitable polymer. The typical thickness of this type of disposable package 165 is approximately 1.0 mm, but can be reduced by choice of material and design. Aluminum foil and polypropylene (or other suitable material) can also be used for the non-sachet type disposable package 166 of FIGS. 50A and 50B, the overall thickness of the package being approximately 1.0 mm to 2.0 mm; Preferably it is 1.0-1.8 mm. In this embodiment, the foil can be used for both the cover and base of the package. The total polypropylene disposable package 167 shown in FIGS. 51A and 51B can be approximately 2.0 mm to 3.0 mm, preferably 2.0 to 2.2 mm thick. These structures can be used for a disposable package with or without the spring disk 46 (FIGS. 61 to 69) and the support member 20, and may have any shape and color. For example, other suitable polymers can be used in place of and in combination with polypropylene.

FIG. 52 shows another embodiment of the disposable package 178, which shows the depth (“ID”) of the contact lens storage space of the disposable package. The depth of the contact lens storage space in this package is measured by subtracting the thickness of the cover material 47 and the thickness of the material forming the base 49 from the height of the package. In other packages, there may be portions that are not used to hold the contact lens. These portions are irrelevant when measuring the depth of the contact lens storage space of the contact lens holding portion. The depth of the contact lens storage space in some of the embodiments of the disposable package of the present invention is approximately 0.1 mm to 3.5 mm, more preferably 0.1 mm to 3.0 mm. Regardless of its size, the depth of the contact lens storage space is always shallower than the height of the curved outer surface relative to the peripheral edge of the contact lens when the contact lens is in an equilibrium state. In equilibrium, the height of the curved outer surface relative to the contact lens periphery is generally greater than 3.8 mm and often 5.0 mm.

In one embodiment of the disposable package 168 shown in FIGS. 53 to 55, the island-like protrusion 42 is in the recess 43 of the base 50, and the contact lens 4 is placed thereon. The contact lens 4 is held in a flat state by the cover 26 of the disposable package and is fixed on the protrusion 42. Further, at least one side of the disposable package may have a non-smooth surface. For example, the non-smooth surface may be a raised ridge or ridge, may be made on one side or on both sides of a disposable package, and may be on a handle. In this embodiment, the relief 44 is on one side of the disposable package, allowing the user to easily grip the contact lens 168, and the cutout 24 at the base corner removes the cover sheet 26. make it easier.

In another embodiment, the disposable package 156 is teardrop shaped and has a cutout 24 in the support member 20 to facilitate handling of the disposable package 156. 56-60 show a teardrop disposable package 156 with or without a cover 26, both opaque and transparent. The side view illustrates the contact lens 4 being held flat until the cover 26 of the disposable package 156 is removed.

63, 65 to 68, when the disposable package 169 is sealed, a polypropylene spring disk 46c may be added to the disposable package 169, and the spring disk may be opened with the disposable package 169 opened. Sometimes it helps to bring the contact lens 4 back to its equilibrium state. As shown in FIGS. 61, 62 and 69-86, various embodiments of spring disks 46a-46t are contemplated in several embodiments of the present invention. A feature common to all the spring disks 46a to 46t is that they are in an equilibrium state. The spring disks 46a to 46t are not flat. However, as shown in FIGS. 63 and 65-68, they can be pressurized and held flat when sealed to the disposable package 169. Various different ways are possible, but two different ways of sealing the disposable package are shown in FIGS. 64 and 68. FIG. In FIG. 64, the two sheet materials 14, 15 are sealed together at one end to form the package 169a and sealed at the other end with the spring disk therein. In FIG. 68, the two sheet materials 14 and 15 constituting the disposable package are sealed and engaged with each other at both ends. As shown in FIG. 65, a breakout notch 40 and a relief 45 may be provided.

FIG. 68 illustrates the arched shape of the spring disk 46c which is in the relaxed state and is arched. However, when the spring disk 46c is placed and sealed between the two sheet materials 14, 15 of the disposable package, it is flattened, and thus the contact lens 4 thereon (FIG. 67). When the disposable package 169 is opened, the spring disk 46c is lifted and is in its arched state, and the contact lens 4 is in a posture that can be mounted immediately. In other words, the lens 4 can be taken out between the thumb and index finger and attached to the wearer's eye (FIG. 68). A perspective view of the contact lens 4 on the spring disk 46e is shown in FIG. As can be seen, the spring disk 46e has a protrusion 51 extending upward toward the contact lens 4 in an equilibrium state. The protrusion 51 holds the center when the contact lens 4 is on it. The peripheral edge of the contact lens is located around the base 53 ′ of the spring disk 46e.

FIG. 69 illustrates a set of members of a disposable package 170 that includes a spring disk 46d. In this embodiment, the spring disk 46d is placed on a molded polypropylene sheet that forms the base 50 of the disposable package 170. The contact lens 4 is placed on the spring disk 46d with the concave surface up, and the disposable package 170 is sealed by the cover 26 made of aluminum foil.

Preferably, the concave surface of the contact lens 4 is placed on the spring disk 46d. However, in another embodiment shown in FIGS. 87 and 88, the convex surface of the contact lens 4 is placed on the spring disk 46e. In this embodiment, the sealed disposable package 191 holds the lens 4 and the spring disk 46e in a flat state, and both return to equilibrium when opened.

Another embodiment is shown in FIGS. 89A-89E, in which the attachment means enabled using spring disk 46e is illustrated. The semi-soft polypropylene spring disk 46e is always arranged in such a direction that the contact lens 4 can be immediately worn on the wearer's eyes. In the figure, the spring disk 46e is placed on the tip of the index finger. Next, the finger passes through the center of the spring disk 46 e and comes into contact with the convex surface of the contact lens 4. The spring disc 46e continues to move through the center of the spring disc 46e by the finger until the spring disc 46e descends to the base of the finger and the contact lens 4 rests on the tip of the index finger. Therefore, the contact lens 4 comes to a position where it can be easily worn on the wearer's eye. Therefore, hand contact is minimized when the contact lens 4 is worn, and the risk of contaminating the contact lens 4 and the eyes is reduced.

In another embodiment, a means for creating a disposable package is provided. In this embodiment, the spring disk is located on top of the contact lens. Next, the minimum amount of hydration medium required is added to the spring disk and contact lens, followed by placing the sheet material above the spring disk and contact lens and below the sheet material. These sheet materials are then sealed. Alternatively, the spring disk and contact lens are inverted before the hydrating medium is added, resulting in contact of the hydrating medium with the contact lens prior to the spring disk. When the sealed disposable package is opened, the spring disk is lifted and the contact lens on it is lifted. However, the balanced contact lens will be placed higher on the balanced spring disk.

A preferred embodiment of the disposable package according to the present invention has a hermetic seal, typically a hermetic seal towards the periphery of the package. As shown in FIGS. 6 and 7, when the package is saw-shaped, the flexibility of the two sheets can be different and the strength of the seal can be varied at the periphery. This makes it possible to open the package by the easiest way to remove the contact lens. Furthermore, the package with the spring disk has a seal inside to be opened in a defined manner, so that the contact lens always appears in a certain orientation. For example, the disposable package 169 of FIG. 68 can have a seal around the circumference. Also preferably, the edge of the disk 46c is attached to the second sheet 15 by a seal, which is more rigid than the seal between the disk 46c and the first sheet 14. When the sheets 14 and 15 are gripped and pulled apart, the sealed seal is first opened, then the first sheet 14 is peeled off from the disk 46c, and the disk 46c remains attached to the second sheet 15. When the package is opened, the center of the elastic portion of the spring disk is always lifted with the lens 4 thereon. (Of course, it is assumed that the direction of the lens and the direction in which the spring disk bounces is constant from the current package to the next package when the package is connected.) And a tip directed to the portion of the package used to peel the first and second sheets. Therefore, the sheet unsealing procedure starts from this tip, and the force required for unsealing is all the power that is poured into the unsealing of the sealed seal at this tip. It is preferable to select a method in which the inner layer of the sheet and the disk are welded to each other by a generally known heat treatment. The disc is formed with a non-planar surface, which affects the way the seal is made and its rigidity, and the disc surface near the portion of the package where the first sheet 14 will be opened first. The discs in the package are positioned so that they can be easily peeled away from each other and to more firmly bond the sheet 14 to the back of the disc. This facilitates opening the package to a suitable stopping point, i.e. where the lens is revealed to be removed from the package.

Disposable packages with and without a spring disk can take a variety of forms. FIG. 90 shows an oval disposable package 171 having a notch 40 that assists the user in tearing the end of the cover 26 from the disposable package 171 to remove the contact lens 4. To do. FIG. 91 is a view in which the cover 26 is removed from the disposable package 171 of FIG. 90 so that the spring disk 46e and the contact lens 4 can be seen. A rounded rectangular variation with cutouts 40 is shown in FIG.

An oval disposable package 192 having a hinged cover 26 is shown in FIGS. 93 and 93A. The cover 26 in this embodiment is sealed around the circumference so that it is peeled off without being completely removed. In other words, the cover is peeled off enough to reveal the contact lens 4, leaving the junction with the disposable package 192 at the hinge 52. Thus, when the seal is opened, the cover 26 turns rearward like a door, and the contents of the disposable package 192 can be taken out.

An asymmetric teardrop disposable package 173 is shown in FIGS. In this embodiment, two breaking cutouts 40 are provided at the narrow end, so that the user can open the disposable package to bring out the contact lens 4 therein. This shape makes it possible to fit two disposable packages 173 onto the disc 54 and store them in a compact manner, making it an ideal choice for consumers on the road.

Several pouch-type disposable packages are shown in FIGS. In FIG. 96, a typical square disposable package 196 with a breaking cutout 40 can be seen. A rounded square disposable package with a more advanced cut end 73 is shown in FIG. In this embodiment, the cut end 73 is more noticeable due to the two middle portions 55, where the foil is cut between the cut end 73 and the body of the disposable package 193. In the mode shown in FIG. 98, a notch 40 extending from the peripheral edge toward the center is provided, whereby the cut end 73 is easily visible.

FIG. 99 shows a square disposable package 175 with rounded corners having a finger-shaped cut end 73 at one end. The cut end 73 is a means for breaking and opening the disposable package 175, and at the same time a means for joining two identical disposable packages 175 as shown in FIG. The finger-shaped cut ends 73 of the two disposable packages are combined with each other to hold the two disposable packages 175 together.

In another embodiment, a double-curved disposable package 176 is presented (FIG. 101). In this embodiment, the upper sheet 14, such as aluminum foil, is bonded to the bottom polypropylene sheet 15 without pleats. The upper sheet 14 can be pulled back to get the contact lens 4 inside. The double curve shape allows multiple disposable packages 176 to be stacked compactly as shown in FIG.

Referring to FIG. 103, the disposable package 177 has a molded polypropylene base 50 and a transparent polypropylene pull top type cover 58. In this embodiment, the pull-top type cover 58 has one end as a starting point for peeling. One end is a part of the pull-top type cover 58, which is not attached to the base 50 and is easily gripped. When the pull-top type cover 58 is removed, the inner contact lens 4 appears.

A variation of the pull top type cover 58 of FIG. 103 is shown in FIGS. In this embodiment, a handle 56 is provided which is higher than the pull-top cover 58 to assist in peeling. As shown in the drawing, when the pull-top type cover 58 is peeled off, the base 50 is bent and the contact lens 4 can be taken out. The handle 56 is provided to provide easy opening for a user with weak finger strength, such as an elderly person, to facilitate gripping the handle 56 and to make the disposable package 178 easier to open. In addition, a key-shaped tip or other device can be used.

In another embodiment, a portion of the base 50 is folded back with the cover 26. 106 and 107, an elongated semi-elliptical disposable package 179 is shown together with the contact lens 4 and the aluminum cover sheet. The base portion 50 is an inner elongated semi-elliptical portion and does not contact the outer peripheral portion 251 except for the vertical edge 255. When the disposable package 179 is opened, both the outer peripheral portion 251 and the aluminum cover 26 are peeled rearward, so that the contact lens 4 therein can be easily taken out.

In the variation of the disposable package 180 of FIGS. 108 and 109, a sharp end 62 is provided on the inner portion 50 of the base to facilitate peeling of the cover sheet 26. The disposable package 180 according to this embodiment has a rectangular shape with rounded corners, but the inner portion 50 of the base has a sharp arch shape. Therefore, when the outer peripheral portion 251 is bent slightly downward, the arch protrusion 62 of the inner portion enters the cover sheet 60, and the sheet is pulled backward along a predetermined path so as to follow the relief. Such a relief 45 is provided for easy opening, and can be a cut with elaborate design, a cut dotted line, or a half cut.

In the embodiment of the disposable package 181 having the polypropylene spring disk 46 g shown in FIGS. 110 to 113, the disposable package 181 has a knob 64. The knob 64 can be folded and broken from the package body via the hinge 127 so that the disposable package 181 can be opened. When the connection between the knob 64 and the main body is broken by folding the knob upward, the protective cover 26 is peeled off, and the contact lens 4 and the polypropylene spring disk 46g appear. When the restraint of the protective cover 26 is removed, the polypropylene spring disk 46g returns to an equilibrium state, like the contact lens 4 thereon, to an arched state. Next, the contact lens 4 can be taken out between the thumb and forefinger and attached to the wearer's eye. In this example, the spring disc 46g is made of polypropylene, but the spring disc 46g is made from other materials known to those skilled in the art, such as suitable polyolefins, silicones, polyamides, polyurethanes and other approved materials. Can be done.

In another embodiment, the disposable package 182 is a retort type package. Referring to FIG. 114, a perspective view of a retort type disposable package 182 according to one embodiment of the present invention is shown. The retort type disposable package 182 has a layered flexible package that holds the contact lens 4. The packet may be formed of one or two pieces of similar or different flexible materials. According to one embodiment, the retort type disposable package 182 is formed of a single piece of flexible sheet material that is sufficient to protect the lens held in the space formed in the package. It is strong enough to be resistant to various impacts, including but not limited to, bent, folded, twisted, rolled, crushed, etc. It has flexibility. The wall of the package is preferably composed of a homogeneous material and does not necessarily need to be adapted to the shape of the contact lens, but rather is configured so that the contact lens floats in the package. Such “floating” is achieved by a fluid force within the enclosed area of the package, which maintains the contact lens from the package surface and acts as a buffer. Since there is little or no air in the package, any internal movement is minimized.

The retort-type disposable package 182 may be formed in a manner that folds the homogeneous material itself back and seals its ends to form a sterile seal. In addition, the retort type disposable package 182 may be formed by sealing two end-to-end homogenous materials at the ends thereof by heat treatment. By dividing the retort type disposable package 182 along one or more ends sealed in a predetermined heat treatment process, the inside lens can be taken out.

In FIG. 114, a retort-type disposable package 182 has first and second barrier layers 14, 15, which can be folded together or combined into two separate layers. Can be formed. The barrier layers 14 and 15 are sealed by heat treatment around the end portions 66, 68, 70 and 72. The ends 66 to 72 sealed by the heat treatment process serve as boundaries that define an internal space 74 in which the lens 4 is accommodated. The lens 4 is immersed in a predetermined minimum amount of the storage solution 48 and kept in a water-containing state (FIG. 115). The barrier layer 15 can be peeled from the barrier layer 14 to remove or reveal the lens. Alternatively, the barrier layer 14 may be peeled from the barrier layer 15. To facilitate initiation of barrier layer stripping, some of the bond engagements between the layers are lightly sealed, preferably at the corners that allow stripping of the barrier layer. FIG. 115 shows a state where the retort type disposable package 182 of FIG. 114 is peeled and opened for taking out the lens.

According to one embodiment, the barrier layers 14, 15 are multi-layer laminates having materials that meet statutory requirements for lens packages. For example, the material of a typical retort type disposable package 182 may consist of a polyethylene terephthalate (PET) layer such as polypropylene, an aluminum layer, a polyolefin layer. A thin layer of aluminum has characteristics such as inherent flexibility and suppression of oxygen permeation, and is therefore suitable as a composite member for a barrier wall.

The retort type disposable package 182 of a predetermined size can be formed from a barrier layer of the same or different material. For one embodiment, the retort type disposable package 182 can be formed by folding a piece of material back to form a space to hold the lens. In other embodiments, two pieces of the same material or two different materials engaged face to face are sealed at their ends by a heat treatment process. According to one embodiment, the barrier material stack can be roughly 10μ PET outer layer, 50μ aluminum layer, 50μ polypropylene layer.

Referring to FIG. 116, the strips 41 of the retort type disposable package 182 are joined to each other by an easily breakable joining portion 76. The retort type disposable package 182 is removed one by one by cutting the joint portion 76. The strip can also be folded at the junction 76, which aids in efficient storage and packaging. Therefore, there is a possibility that 6 to 8 lenses or more can be accommodated in a space of the same size as that used to accommodate 2 lenses in the prior art blister pack 27.

In FIG. 117, the strip including the retort-type disposable package 182 of FIG. 116 is shown with the hydration solution pack 35 attached to the package 182 through the joint portion 76. The hydration solution pack 35 may be used by consumers for the purpose of hydrating the lens when it is necessary to refill the lens.

Another embodiment of the disposable package 201 of the present invention is shown in FIGS. In this embodiment, package 201 is relatively flat, like package 169 shown in FIGS. 67 and 68, and consists of two laminate materials 202, 204 and spring disk 206. Of course, the package 201 also includes the contact lens 4 and saline solution (not shown), and other prints such as decorative prints and lens parameters can be provided on the top and back outer surfaces. Instead of being formed from two separate sheets, the upper sheet 202 and the bottom sheet 204, the package 201 can be formed by folding one sheet and trimming it to the shape shown. The spring disk 206 preferably has a diameter of about 21 mm, the outer ring structure is about 0.5 mm thick, the central leaf spring portion is about 0.3 mm thick, and the leaf spring portions are about six as shown, each penetrating therethrough. A large number of small holes.

The package 201 is considered to be peeled off and opened, and a simple opening peel shaped so that the force required to start opening the package is substantially equal to the force required to continue opening the package. It is formed with a seal. A preferred package is about 40 mm long and about 30 mm wide. The package is preferably made from a laminate material 203 as best shown in FIG. A suitable laminate for package 201 is an easy peel film commercially available from Hosokawa Yoko CO. LTD., Tokyo, Japan. In one embodiment of the laminate 203, there are five layers. Inner layer 205 is an easily peelable sealing material such as polypropylene, preferably about 35 microns thick. The second layer 207 is preferably a 15μ polypropylene film and is bonded to the first polypropylene layer. The third layer 209 is preferably a 35μ aluminum layer. The fourth layer 211 is preferably a 3μ backprinted layer. The outermost layer 213 is preferably a 12μ PET layer. Of course, the layers can be of different thicknesses to meet different needs, and can be more or less. For example, a co-extruded polyurethane binder can be applied between layers 205 and 207 and between layers 207 and 209. Also, although a 35 μm aluminum layer is preferred, the aluminum layer can be as thin as 7 μm or as thick as 70 μm. With a thickness of at least 15μ, aluminum serves as an oxygen barrier. Other laminates are laminated to easily peelable polypropylene 35μ first layer, binder layer, 12μ PET layer, another binder layer, 20μ aluminum layer, other binder layer, and finally other film. It can have a 12μ PET layer that can be pre-printed. The binder layer may be dry lamination. Of course, the easily peelable polypropylene layer is on the inside of the package.

Two seals are formed in the package 201. First, the spring disk 206 is fixed to the bottom sheet 204 with a seal 208 (FIG. 167). The seal is made with such strength that the disc 206 remains attached to the bottom sheet 204 when the package is opened. The upper sheet 202 is sealed to the bottom sheet 204 with a peel seal 210. The peel seal 210 completely surrounds the disk 206 and seals the package 201. The seal 210 has a special shape with an introduction 212 in the form of a pointed portion that extends outwardly from the remaining seal 210. Pointed portion 212 is directed to the near side 214 of the package that is initially opened. As shown in FIG. 169, the package 201 is opened by separating the two sheets 202 and 204 at the front side 214 of the package. The sheets are easily separated because they are not in sealing engagement with each other on the front side (ie, both front end portions are not in sealing engagement with each other). When the upper sheet 202 is peeled off, the first portion of the seal 210 that comes into contact with and peels off is the pointed introduction portion 212. As the upper sheet 202 continues to be pulled backward, the seal 210 continues to be peeled off and an opening is formed in the lens housing. As shown in FIG. 169, at this stage, the peel seal 210 separates the entire width of the introduction portion 212, but the remaining portion of the seal 210 remains as it is. The upper sheet 202 continues to be peeled off until the position shown in FIG. 170 is reached, completely opening the package and exposing the lens 4. As in the other embodiments, when the package 201 is opened, the center of the spring disk 206 pops up to lift the lens to a position where it can be easily picked by the user.

FIG. 172 is a graph showing the force required to open a typical blister package and package 201 as a function of time. These graphs represent the force applied when the package was opened using a constant speed tension meter. The part holding the sheet was released at a constant speed and the force used was recorded. Line 214 shows the force required to open a typical blister pack seal as shown in FIG. When the first part of the seal is met, the force reaches peak 216. Thereafter, the force required to continue to open the package decreases dramatically, reaching the low region 218 of the graph. Then, when the base of the lid is completely removed, the required force reaches the second peak 220.

Peaks 216 and 220 are typical blister pack seals where the seal shape is annular (approximately the same shape as the seal 208 used to seal the spring disc 206 to the bottom seat) around the entire circumference of the ring. Caused by having a constant radial thickness. Because the lid material is flexible, the lid is pulled back in such a way that the package peel point between the lid material and the blister base forms a line that moves across the package. The force required to open the package is proportional to the length of the part where the line meets the peel area. First, the line touches the outside of the ring. However, as the package seal begins to open, the length of the intersecting line portions increases rapidly to the highest point, which is a function of the ring circumferential length and radial thickness. As soon as the line moves to the point where it broke through the seal, it then intersects two different parts on the same line of the seal. However, since the length of the intersecting line portions decreases as the line approaches the center of the seal, the force required to open begins to decrease rapidly as the package is further opened. Since both sides of the seal are opened at the same time, the total amount of seals that need to be opened is just twice the thickness in the circumferential direction. Thereafter, the force begins to increase again and reaches the peak 220 when the separated line of the seal meets the back side of the seal again. If the lid is completely removed, the force will, of course, decrease rapidly as the seal area to be separated decreases.

The curved shape of line 214 represents a real problem that users face when trying to open a prior art blister pack. They must apply enough force to open the first part of the seal so that the seal begins to break through, and if they do not react quickly by reducing the force they are applying, the rest of the seal The blister pack will fall apart and the blister pack will flip over if not firmly pressed onto the sink, throwing out the solution containing the lens in water or the lens contained in the package. When this happens to the user, they learn to open the seal by pulling the lid off in a rocking manner so that the required force can be adjusted more easily.

The combination of Hosokawa Laminate's use with the seal introducer 212 of the package 201 generally improves the force curve 222. As can be seen on the right side of FIG. 172, the force required to continue to open the seal 210 remains in the narrow range of the peak force 224. Preferably, the force peak does not exceed 150% of the minimum force required to open the remainder of the seal. It should be noted that the peak pressure 224 required to open the seal depicted in the graph is significantly less than the peak pressure 216 required to open the prior art blister pack. In the inventive package, the length of the seal range of the package is quite long, so the time required to open the inventive package seal is longer than the time required to open the prior art blister package.

The force required to open the seal is a function of the extent and shape of the seal, the materials that are sealingly engaged with each other, and the temperature and pressure applied to the formation of the seal if a heat sealing process is used. A preferred seal is formed at a pressure of about 6 bar, a dwell time of about 1 to 2.5 seconds, and a temperature between 180 ° C and 200 ° C. The preferred width of the sealing areas 208 and 210 are both 2 mm.

FIG. 118 shows an exploded view of carton 84 according to one embodiment. The carton contains a number of packages that are the same as the package 82 that houses the strip 41 of the retort type disposable package. The package may also contain a plurality of individual retort type disposable packages 182. In this configuration, it can be seen that a larger number of lenses can be accommodated in a space per unit than in a conventional package. Depending on the packing density, up to 10 lenses, possibly 10 or more lenses, could be accommodated in a space that would have previously accommodated 2 lens packages.

The described retort type disposable package 182 preferably has one soft contact lens each. Appropriate illustrations and statutory information may be applied to the exterior surface in a manner similar to currently distributed packages.

The integrity of the lens contained in the retort type disposable package 182 is maintained by buffering the storage solution in the surrounding package. The storage solution can act as a safe buffer when the lens package is handled rough or damaged. The blister packs that are currently in circulation use lens protrusions or pre-formed rigid boats as lens protection barriers. However, prior art blister packs have an aluminum foil cover to close the opening of the pinch lister pack. The foil without the back has no special protection and is less protective than the retort type disposable package which has two conformable barrier layers on the foil side that more effectively respond to the loads it receives. In fact, the aluminum outer surface of the blister pack can be more easily drilled because it is passed loosely into the polypropylene boat. Retort-type disposable packages are inherently flexible and divert the possibility of being drilled by moving with the object that causes the hole to be drilled.

The retort pipe disposable package 182 includes the minimum amount of storage solution necessary to maintain water content and unlike the prior art package, the lens is not required to be immersed in the storage solution.

In one embodiment of the present invention of a retort type disposable package 182 according to the present invention, a preserving solution or gel for maintaining the lens in a water-containing state is left in the manufacturing process, and a predetermined amount of preserving fluid or gel is excluded, and excess water-containing fluid is excluded. Can be done. There is no evaporation from the interior space due to the best sealing in the retort type disposable package 182. This flatness of the package barrier layer has the advantage of facilitating adhesion of the lens to any inner surface. When the layer is peeled off and the internal lens is revealed, the lens adheres to the inner surface, ensuring that the lens does not spill upon opening.

The manufacture of disposable lenses is more cost effective by reducing the cost of packaging the lens and improving the effectiveness of the seal and the resulting sterility. In the packaging of the present invention, the patient will more likely regard the lens as a disposable item. Moreover, the lens takes up much less space and can be packaged in a more interesting way. This type of packaging is particularly suitable for daily disposable lenses because the cost structure of this type of packaging is attractive to both consumers and manufacturers.

Various secondary packaging 86 configurations may be implemented in the disposable package shown in FIGS. 119-164. The advantage of the disposable package is that various secondary packages can be selected. Furthermore, the space required for packaging multiple disposable packages is much less than conventional blister packs. For example, FIGS. 119 and 120 show a package that accommodates 30 disposable packages 187. Five disposable packages 187 are accommodated in each of the six sections 90 sealed with a cover sheet 88, for example, vacuum-formed PET. As shown in FIG. 120, the sections 90 are connected by a cover sheet 88. Two packages such as 86 can be combined to provide 30 days worth of contact lenses (ie, a total of 60 lenses) (FIG. 121). In this embodiment, the 30-day supply is only 270 × 60 × 12 mm in size. The 90-day supply of lenses (FIG. 122) is only 270 × 180 × 12 mm, and the 180-day supply package (FIG. 123) is 270 × 240 × 20 mm. The size of the pack for 30 days, 90 days, and 180 days can be changed as follows, but is not limited thereto. Packaging for 30 days can be 300 x 60 x 12 mm, or 255 x 60 x 13 mm, or 250 x 60 x 13 mm, or 245 x 60 x 13 mm, or 240 x 55 x 13 mm. A 90 day supply pack can be 300 × 180 × 12 mm or 255 × 180 × 13 mm, or 250 × 180 × 13 mm, or 245 × 180 × 13 mm, or 240 × 165 × 13 mm. The packs supplied for 180 days can be 300 × 240 × 20 mm, or 255 × 240 × 20 mm, 250 × 240 × 20 mm or 245 × 240 × 20 mm, and 240 × 220 × 20 mm.

In another example, FIG. 124, a secondary package 124 for two disposable contact lens packages is illustrated. In this embodiment, two contact lens packages are housed in a substantially compact secondary packaging business card size of about 3 _^1/2 inch to about 2 inches (about 90mm to about 50 mm). This embodiment is particularly useful when traveling.

Another embodiment shown in FIGS. 125A and 125B is a secondary package 86a for 30 disposable packages 187, each having three compartments 90 that contain 10 disposable packages 187. FIG. The compartments 90 are connected to each other by a single cover sheet 88. The package 86a is extremely small and its dimensions are 130 × 60 × 11 mm.

As shown in FIGS. 126 to 133 and 135 to 136, one example is a handbag and travel pack 91 having a plurality of disposable packages 163. The disposable package therein may be a separate disposable package or a strip of disposable packages folded in a zigzag shape. Travel pack 91 is made of a transparent or opaque (FIG. 131) material. The travel pack can be opened by pressing the release button 93 so that the lid 89 turns around. The travel pack may have a mirror 94 on the inside, which allows the user to wear a contact lens anywhere and at any time during the trip. Furthermore, the travel pack 91 is provided with a handle 92 as a means for hanging the travel pack, for example, so that the travel pack 91 is at eye level or hooked to a safe place (FIG. 130). Yes. As shown in FIG. 129, the disposable package 163 is held in the travel pack 91 by the slide guide 96 preventing the disposable package 163 from slipping down. In another embodiment of the travel pack 91a, the disposable package 163 is held in a partition 98 as shown in FIG. 132, optionally with L (left) and R (right) marks 100 displayed on the partition. Also good.

In another embodiment, as shown in FIGS. 133-135, the secondary package provides a 90-day disposable package 163. 133 and 134 are front views of the 90-day container, and FIGS. 135 and 137 are side views. The 90 day container 104 is a cover that can be optionally attached to a stacked disposable package 163 (either an independent or zigzag strip) and the travel pack 91 (FIG. 133) described above. 102. As shown in FIGS. 133 and 135, the travel pack 91 can be slip-fit onto the cover 102 of the container 104 for 90 days.
