The externally-applied agent for skin comprises liquid components which subpackage into a container body with bulges, wherein the container body can deform when being pressed by user, and the liquid component can flow out from the position which is punctured at a sealing part of the container body, thereby immersing the coating component, when the externally-applied agent is at 30 DEG C, the viscidity of the liquid components is 300mPa.s to 3000mPa.s.

Description

The present invention relates to a container-away have used, to single-use container containing a skin Hadagaiyo agent for improved particularly good and Use of the impregnation of the coating member.

  For example, cosmetic containers for use in so-called pouch packs, etc., in which liquids or cream-like cosmetics as external preparations for skin are subdivided into resin sachets or the like as samples and hermetically sealed. Is known).

  Here, in a conventional single-use type container, a cosmetic material is impregnated in advance with an application member such as a nonwoven fabric, and the application member is taken out from the container and used at the time of use. Therefore, conventionally, problems such as discoloration, odor change and the like have been observed depending on the liquid composition of cosmetics and the like due to the content liquid contained in the coating member for a long period of time. Further, depending on the material of the nonwoven fabric, the antiseptic property of the liquid is lowered, so that a device for prescription or the like is necessary.

  Therefore, cosmetics, etc. are stored little by little, and as a single-use container intended to be used up once, skin external preparations such as cosmetics can be easily discharged and penetrated into a sheet of cotton (applying member). A cosmetic container having a configuration that can be used by applying the cosmetic to the skin using the sheet is known (see, for example, Patent Document 1).

In the technique disclosed in Patent Document 1, for example, a rupture protrusion capable of pressing and breaking the seal member is formed on the bottom of the storage recess for storing the external preparation for skin, and the seal member is used when the external preparation for skin is not used. The seal member protrudes in the direction of the seal member at a height that does not come into contact, and when the external preparation for skin is used, the bottom portion of the storage recess is pressed and deformed in the direction of the opening portion, so that the seal member is formed at the tip of the breaking protrusion protruding from the bottom portion. The external skin preparation can be discharged to the outside.

  By the way, even in the above-described cosmetic for use up, for example, in the case of a user's eyes or cheeks, an amount of cosmetic to be applied to both the left and right is required. Therefore, the amount of makeup used per time may increase. For example, if the amount of makeup used for one time is 2 ml, the volume of the container and the volume of the container will increase as the content increases. The breaking protrusion for breaking a part is inevitably large. As a result, in the conventional cosmetic container, a strong force is required when pressing the fracture protrusion with the seal member, so that the finger to be pressed becomes painful or the container body comes from the end or the adhesive surface with the seal member, etc. There is a possibility that the external preparation for skin leaks out and gets dirty due to puncture or puncture.

<Outline configuration diagram of cosmetic container (single-use container)>
FIG. 1 is a diagram illustrating an example of a schematic configuration of a cosmetic container (a single use container). The cosmetic container 10 shown in FIG. 1 is roughly configured to include a covering tray 11, a container body (portion) 12, an application member (applicator) 13, and a film member 14.

  In FIG. 1, the cosmetic container 10 holds the container body 12 and the two coating members 13-1 and 13-2 in a predetermined position by adhesion between the covering tray 11 and the film member 14. It is to be sealed. In addition, the cosmetic container 10 is pressed and deformed from the outside by pressing with a finger of a user or the like from outside, and the sealing member 22 or the like is pressed by the breaking protrusion 21 in the container body 12 therein. Break. Due to this pressure rupture, the external preparation for skin contained in the container body 12 is discharged from the ruptured portion to the outside, and the discharged external preparation for skin is arranged at a preset position on the outer surface of the seal member 22. The coating members 13-1 and 13-2 are impregnated from the appropriate positions (for example, positions where the entire center, center of gravity, etc. are easily impregnated).

  Here, impregnation means, for example, a state in which an external preparation for skin is impregnated or applied to a sheet-like application member, or a state in which moisture is dried and removed from the application member after impregnation with an external preparation for skin, and insufficient removal of moisture. (For example, including concentration and the like). In addition, the application members 13-1 and 13-2 are not limited to the above-described cotton, and it is only necessary that the external preparation for skin can be adsorbed and held on the surface. Specifically, for example, any one of a sponge member, a flocky (electrodeposition flocking) member, a nonwoven fabric, or a mixed material thereof can be used as the application member.

  Further, a skin external preparation such as cosmetics is impregnated in both of the application members 13-1 and 13-2, and the impregnated application members 13-1 and 13-2 are respectively predetermined around the left or right eye. The cosmetic can be applied to a predetermined site by sticking to and sticking to the position. Here, since the application members 13-1 and 13-2 are impregnated with the external preparation for skin, the application members 13-1 and 13-2 can be applied to the user's skin with the moisture.

  In the present embodiment, the covering tray 11 and the container body 12 can be formed to be transparent or translucent, and thereby the appearance of the color of the external preparation for skin and the state of impregnation of the external preparation for skin to the application member Can be easily confirmed.

  Here, FIG. 2 is a diagram showing an example in which the cosmetic container shown in FIG. 1 is integrally sealed. 2A shows an example of a top view of the cosmetic container, FIG. 2B shows an example of a cross-sectional view taken along the arrow AA ′ of the cosmetic container, FIG. 2C illustrates an example of a cross-sectional view taken along the line BB ′ viewed from the direction of the arrow, and FIG. 2D illustrates an example of a back view.

  Here, in FIG. 2, the covering tray 11 is formed with an accommodating convex portion 31 for accommodating the container main body 12 therein. Further, the cosmetic container 10 has a recess 20 formed on the covering tray 11 so that the container can be pushed by a user's finger or the like.

  Further, the coating tray 11 accommodates the coating members 13-1 and 13-2, and the skin external preparation that is discharged when the sealing member 22 is broken from the container main body 12 by the breaking protrusion 21 described above. It has the convex part 32 for application members which has the space for impregnating the whole of -1 and 13-2.

  The film member 14 is formed to have substantially the same dimensions as the covering tray 11, and seals the container main body 12 and the coating members 13-1 and 13-2 by being sealed with the covering tray 11. In addition, although the film member 14 uses, for example, a PE (polyethylene) film, other resin films may be used, and the skin external preparation adhered to the coating members 13-1 and 13-2. Depending on the type, paper or metal foil may be used. Further, as the material of the back surface (outside) of the film member, PET (Polyethylene terephthalate), NY (Nylon (registered trademark) (Nylon)), and other resin films can be used.

  Furthermore, the coating tray 11 was not broken by the breaking projection 21 but the end portion which is the sealing portion between the container body 12 and the sealing member 22 was broken by pressing or the like, and the skin external preparation was discharged from the place. Occasionally, a groove 33 is formed around the storage portion of the container so that the external preparation for skin stays at a predetermined position. Thereby, even if it is a case where it fractures | ruptures from the circumference | surroundings of a storage part and a skin external preparation is discharged, the leak of a skin external preparation etc. can be suppressed. Moreover, the rigidity of the coating tray 11 itself can be ensured by forming the groove portion 33. In addition, the sealing member 22 in this embodiment can select and use the material which is comparatively easy to break, such as metal foil, such as aluminum, paper, cloth, etc. according to the skin external preparation to accommodate.

  Further, the cover tray 11 is formed with a bent portion 34 that can be easily bent to the left and right with respect to, for example, AA ′, and is bent by the bent portions 34-1 to 34-3. The break protrusion 21 can easily break the seal member 22.

  The bent portion 34-1 is formed on the covering tray 11, and the bent portions 34-2 and 34-3 are formed in a total of two in the vertical direction with respect to the gap AA ′ on the groove portion 33. Yes. Thereby, it can be made easy to make it fracture | rupture from desired positions (for example, center position of the container main body 12, etc.) by folding the covering tray 11 at the time of use.

  Further, since the covering tray 11 is designed to cover the entire surface of the container body 12 in order to prevent leakage, it is necessary to provide a hole through which air escapes. Therefore, the covering tray 11 may be configured to have at least one air hole discharged from the container body 12. In addition, as a position of an air hole, it is preferable to provide in the recessed part 20 or its periphery, for example. Specifically, for example, air holes 35-1a and 35-1b are provided at predetermined positions on the outer periphery of the recess. By providing an air hole at this position, the container body 12 is the most recessed portion when crushed by pressing deformation, so that it is possible to prevent leakage of the external preparation for skin from the air hole.

  Moreover, as a position of an air hole, it is not limited to the above-mentioned air holes 35-1a and 35-1b, For example, you may provide air holes 35-2a and 35-2b in the ridgeline part formed of the dent part 20. The air hole 35-3 may be provided in the center of the recess 20.

  Furthermore, it is sufficient that at least one air hole is formed, but even if two or more air holes are provided, one of the holes may be blocked by a finger, and the other hole is open, so that the pressure is deformed ( It is possible to prevent internal sealing during opening. Thereby, smooth penetration to the application member of the external preparation for skin can be promoted.

  In this embodiment, as shown in FIG. 2 (D), the covering tray 11 and the film member 14 are provided with the four-corner seal areas 36-1 to 36-4. The goblet seal region 36 is a region formed of a set that is partially bonded (sealed) with a minute uneven pattern. Thereby, the covering tray 11 and the film member 14 can be peeled off smoothly.

  In order to make it easy to peel off from the covering tray 11, grip margins 37-1 and 37-2 may be provided in the gouge-eye seal region 36-1 and the seal member 36-4.

  The goose-eye seal areas 36-2 and 36-3 are not provided with a finger in consideration of easiness of opening when the user opens from the goose-eye seal area 36-1 or 36-4. That is, since the force is applied substantially in parallel to the seal portion (ring seal 38) when opening from the side of the gouge eye seal regions 36-2 and 36-3, a considerably strong opening strength is required at the time of opening. For this reason, the finger clasp is eliminated so that the seal cannot be opened from the side of the gouge eye seal regions 36-2 and 36-3. In addition, it is possible to secure a large area of the grip margins (finger hooks) 37-1 and 37-2 so that the user can easily open the seal by lowering the entire seal portion by, for example, about several mm.

  Here, as shown to FIG. 2 (B), it is preferable that the radius of chamfer R1 of the ridgeline part obtained by providing the recessed part 20 shall be about 2.0-3.0 mm. If the radius is smaller than about 2.0 mm, the tip becomes sharp when the user presses and crushes the dent 20 from the outside with a finger or the like, and the finger becomes painful, and the radius is about This is because, when it is larger than 3.0 mm, the ridge line becomes inconspicuous and is difficult to recognize as a place to be pressed with a finger.

  Further, as shown in FIG. 2D, it is preferable that the radius of the chamfered portion R2 of the ring seal 38 is slightly increased. Thereby, when opening from one side, a seal part can be peeled off smoothly without changing the direction of hand-handling or peeling off in the middle.

  The radius at this time is preferably larger than about 10 mm, for example, and is preferably smaller than about 15 mm. This is because, when the radius of the chamfered portion R2 is smaller than about 10 mm, it is difficult to peel it once unless the hand is changed, and when the radius is larger than about 15 mm, the recessed portion of the covering tray 11 is formed. This is because the coating member 13 is greatly deviated from the original set position during transportation, for example. Therefore, specifically, the radius of the chamfered portion R2 may be in the range of about 10 to 15 mm, for example, and is particularly preferably in the range of about 12 to 14 mm.

  Furthermore, the seal width of the ring seal 39 that seals the inside by adhering the storage portion of the container main body 12 and the seal member 22 shown in FIG. In order to prevent this, the ring seal width of the potion can be arbitrarily changed according to the volume of the external preparation for skin. The ring width of the ring seal 39 is preferably about 2 to 3 mm, for example. This is because when the ring width is smaller than about 2 mm, the frequency of puncture increases due to insufficient sealing strength, and when the ring width is larger than about 3 mm, the remaining skin external preparation is taken with a finger. This is because it becomes difficult to peel off.

  For example, when the seal width is about 1.5 mm, the seal peel strength is about 10 N, and when the seal width is about 3.0 mm, the seal peel strength is about 15 to 20 N. That is, by increasing the width of the ring seal 39 in the container body 12, the seal strength is increased and the frequency of punctures can be suppressed. In the present embodiment, even if the container is punctured, the back surface of the container main body 12 is covered with the covering tray 11, so that leakage due to rebounding can be prevented, and no contamination to the surroundings occurs.

<Another embodiment of coating tray 11>
Next, another embodiment of the covering tray described above will be described with reference to the drawings. FIG. 3 is a diagram illustrating an example for explaining an example of another embodiment of the covering tray.

  As shown in FIGS. 3A to 3C, the coating tray 41 has a “PUSH” mark 42 in the center, and has at least one predetermined shape so that the pressing position becomes clear. A convex portion 43 is provided. Thus, by using the covering tray 41 as shown in FIG. 3, the user can clearly know the position to push, and can press the dent portion with certainty. In the example shown in FIG. 3, three round-shaped convex portions are arranged in parallel. However, the present invention is not limited to this. For example, the number, position, shape, etc. of the convex portions are designed. It can be set arbitrarily in consideration.

  Here, FIG. 4 is a diagram showing an example of another convex shape in the covering tray. For example, as shown in FIG. 4A, the convex shape in the present embodiment may be a triangular convex portion 44-1, a rectangular convex portion 44-2, or a star. The convex part 44-3 of shape may be sufficient.

  In addition, although the “PUSH” mark 42 is engraved on the covering tray 41 shown in FIG. 4, other characters (including other languages) may be written, and no mark is written. Also good. Furthermore, only the mark may be engraved and the convex portion may not be formed, or the concave portion may be formed instead of the convex portion.

  Moreover, FIG. 5 is a figure which shows an example of other embodiment of the back surface of a coating | coated tray. For example, like the covering tray 41 shown in FIG. 5, the goby eye seal regions 36-1 and 36-4 shown in FIG. 2D are not straight but curved inward so that the fingers can easily grasp them. Also good.

  Further, the covering tray 11 shown in FIG. 2 (D) does not have a grip margin (finger grip) in the gouge seal areas 36-2 and 36-3, but as shown in FIG. A gripping allowance may be provided in the areas 36-2 and 36-3 so that the seals can be opened from the gossamer seal areas 36-2 and 36-3. Further, the adhesive area of the goza-eyed seal areas 36-2 and 36-3 may be curved toward the center of the container so that the grip margin is widened.

<About the shape of the container body>
Next, a specific example of the shape of the container body will be described with reference to the drawings. FIG. 6 is a diagram showing an example of the container body shape in the present embodiment. 6A to 6C show a view of the container body 50 from above and a cross-sectional view thereof. Here, the shape of the container main body shown in FIG. 6 is preferably a shape that is pushed straight during use because the cause of the puncture is that the container main body is pushed obliquely. In use, the finger is not hurt when the portion is pushed in with the user's finger or the like.

  Here, in each of the container main bodies 50-1 to 50-3 shown in FIGS. 6A to 6C, the skin external preparation 52 is accommodated in the accommodating portions 51-1 to 51-3 and sealed by the seal member 53. Has been. Here, the storage units 51-1 to 51-3 are pressed from the outside of the storage units 51-1 to 51-3 with a finger or the like, for example, in the direction of arrow F shown in FIGS. The external form of the skin is deformed, and the tip of the breaking protrusion 54 at the center breaks through the seal member 53, thereby discharging the external preparation for skin.

  Here, it is preferable that the thickness of the accommodating parts 51-1 to 51-3 is about 0.1 to 0.3 mm. Thereby, it can prevent that a finger becomes painful at the time of the press deformation of the accommodating part 51. FIG. The accommodating part 51 is formed of, for example, a PP (polypropylene) sheet or other resin. In addition, if the buckling strength when pushing the corner portion at a speed of about 50 mm / min is about 30 N or less, no pain is felt.

  For example, in the container main body 50-1 shown in FIG. 6A, the dent 55 is provided at the center, and both the thumbs of the user are placed on the dent 55, so that the breaking protrusion 54 can be made substantially vertical. The seal member 53 is reached, the seal member is broken, and the skin external preparation 52 can be discharged (dotted line portion in FIG. 6A).

  Furthermore, in the recessed part 55 of FIG. 6 (A), it is preferable that the radius of the chamfered part R3 is about 1.5 to 2.0 mm. This is because when the radius of the chamfered portion R3 is smaller than about 1.5 mm, the tip of the ridge portion of the container main body and the covering tray is sharp when pressed and deformed during use, and it hurts when touched by a finger. In addition, when the radius of the chamfered portion R3 is larger than about 2.0 mm, the ridge line is not conspicuous and is difficult to recognize as a place to be pressed with a finger.

  Furthermore, the radius of the chamfered portion R4 is preferably about 20 to 30 mm. Thereby, the concave shape corresponding to the shape of the finger can be formed.

  In addition, the radius of the chamfered portion R5 in FIG. 6A and the chamfered portion R6 in FIG. 6B is preferably about 1.5 to 2.5 mm. This is because if the radius of the chamfered portions R5 and R6 is smaller than about 1.5 mm, it will hurt when touched with a finger at the time of use, and if it is larger than 2.5 mm, the straight portion of the corner projection becomes shorter, It is because it becomes hard to be crushed by the intensity | strength of a corner | angular part, and it also hurts when it hits a finger.

  In addition, the shape of the accommodating part in this invention is not limited to this, For example, as shown to FIG. 6 (B), you may make it the structure which does not have the recessed part 54, and FIG. ), A finger print portion 56 may be formed and a finger placed on the place to be pressed.

  In addition, the container body shape can be provided to a user or the like by storing a suitable amount of the skin external preparation according to the purpose of use by providing a recess appropriately corresponding to the amount of the skin external preparation.

  In addition, it is easy to give the container body airtightness and liquid-tightness by using resin material, aluminum foil, etc. for the storage part and sealing member. Can be provided without leaks.

  Here, two or more breaking protrusions 54 shown in FIG. 6 may be provided, and the tip shape may be, for example, a conical shape or a polygonal pyramid shape.

  As described above, according to this embodiment, a single-use type cosmetic container with improved usability can be provided. Moreover, according to this embodiment, a cosmetic container with good usability can be provided even when the content volume of the external preparation for skin is increased.

  Therefore, according to the present invention, it is possible to provide a skin external preparation for improving the usability by improving the impregnation of the application member, and a single-use container storing the skin external preparation.

<About external preparation for skin>
Next, skin external preparations such as cosmetics corresponding to single-use type containers as described above will be described in more detail using examples. However, the technical scope of the present invention is limited by these examples. Is not to be done. Moreover, unless otherwise indicated, the compounding quantity in the Example etc. of the skin external preparation shown below shows the weight% with respect to the whole system by which the component is mix | blended.

Moreover, unless otherwise indicated, the compounding quantity of the hydrophilic component in the Example etc. of the nonwoven fabric material shown below, and a hydrophobic component shows the weight% with respect to the whole system by which the component is mix | blended.

  FIG. 9 is a diagram showing an example of the difference in impregnation speed and the degree of satisfaction due to the difference in the nonwoven fabric material. In addition, in FIG. 9, the impregnation speed | rate and satisfaction in case the nonwoven fabric material is comprised only with the hydrophobic component are also shown as a comparative example.

  As shown in Examples 1 to 7 of the nonwoven fabric material shown in FIG. 9, when the hydrophilic component is included in the constituent material of the nonwoven fabric material impregnated with the liquid component, a good impregnation rate can be realized and further used. Satisfaction of time can be obtained.

  In addition, as a hydrophobic component, PP (polypropylene), PET (polyethylene terephthalate) etc. can be used, for example, As a hydrophilic component, there exist cotton, a pulp, rayon, paper etc., for example. Here, if the amount of the hydrophilic component in the nonwoven fabric material is too small, the impregnation rate becomes slow. Further, although the degree of satisfaction was slightly different depending on the blending amount of the hydrophilic component, there was no difference in size, and a satisfactory impregnation rate could be obtained. Therefore, it can be said that the blending amount of the hydrophilic component is preferably about 10% or more.

<Difference in impregnation speed due to difference in fabric weight and degree of satisfaction>
Next, the difference in the impregnation speed due to the difference in the basis weight of the nonwoven fabric and the satisfaction will be described. FIG. 10 is a diagram illustrating an example of a difference in impregnation speed due to a difference in basis weight of nonwoven fabric and an example of satisfaction.

The basis weight is the mass per unit area (g / m ² ). In FIG. 10, the nonwoven fabric material is 100% cotton (Example 7 of nonwoven fabric material). Furthermore, the thickness of the nonwoven fabric material in FIG. 10 is about 0.41 to 0.47 mm, although there are some errors depending on the measurement position.

According to FIG. 10, if the basis weight of the nonwoven fabric is about 20 g / m ² , it is felt that it is slow, but if it is about 40 to 100 g / m ² , 12 to 15 people are satisfied with the impregnation speed and at the time of use. Is pleased. That is, as shown in FIG. 10, when the basis weight is small, the impregnation rate tends to be slightly slow, and the basis weight is preferably about 40 g / m ² or more. Further, if the basis weight is small, the amount of impregnation is reduced and the satisfaction during use is lowered. Therefore, the basis weight is preferably about 40 g / m ² or more.

<Speed of impregnation into nonwoven fabric and degree of satisfaction by hole size (area) of sealing member>
Next, in the above-described cosmetic container, the impregnation rate and the degree of satisfaction of the nonwoven fabric depending on the size (area) of the hole opened in the sealing member by the break protrusion will be described. FIG. 11 is a diagram illustrating an example of the impregnation rate and the degree of satisfaction of the nonwoven fabric depending on the hole size (area) of the seal member.

Here, as shown in FIG. 11, it can be said that the impregnation speed is not good when the size of the hole opened by the break protrusion is about 0.01 to 0.13 mm ² , for example. However, when two or more holes of this size are formed in the seal member, the satisfaction is improved.

In addition, when the size of the hole is, for example, about 78 mm ² or more, only a part of the nonwoven fabric (application member) is impregnated, and the whole is difficult to impregnate. Therefore, according to FIG. 11, the size of the holes may have about 0.20～80Mm ^2, preferably in particular about 0.7～65Mm ^2, more liquid component is likely situation impregnated into the nonwoven fabric.

  In addition, the satisfaction mentioned above is calculated | required by calculating | requiring an average value etc. from the result obtained from at least 1 of Examples 1-5 of a skin external preparation, for example. Furthermore, as shown in Examples 1 to 5 of each of the above-mentioned external preparations for skin, in this embodiment, the liquid component as the external preparation for skin can be suitably applied such as transparent, emulsion, or translucent.

  As described above, according to the present invention, it is possible to provide a skin external preparation for improving the usability by improving the impregnation of the application member, and a single-use container storing the skin external preparation. Specifically, according to the above-described embodiment, a single-use type cosmetic container with improved usability can be provided. Moreover, according to this embodiment, a cosmetic container with good usability can be provided even when the content volume of the external preparation for skin is increased.

  In addition, since the above-described cosmetic container is a transparent or translucent container body, the color of the skin external preparation can be easily confirmed from the outside, particularly in the case of a skin external preparation whose color is important, such as lipstick and foundation. . Therefore, it becomes possible for the user and the user or the like to make a selection according to his / her preference, and a product having excellent functionality as a product or a sample can be obtained.

  Moreover, in the above-mentioned cosmetics for cosmetics, in the external preparation for skin use, which is used by pressing a container with a protrusion containing a liquid component with a finger at the time of use and impregnating the liquid into a nonwoven fabric, the viscosity of the liquid component is about 300 to 3000 mPa · It is s / 30 ° C., preferably about 600 to 2000 mPa · s / 30 ° C. Furthermore, in the external preparation for skin in the present invention, it is preferable that at least 10% of a hydrophilic component is contained in the constituent material of the nonwoven fabric material impregnated with the liquid component.

The skin external preparation of the present invention preferably has a basis weight of a nonwoven fabric impregnated with a liquid component of about 40 to 100 g / m ² or more, and further has a size (area) of a hole opened by a protrusion of about 0.20. about 80 mm ² well, especially about 0.7～65Mm ² is preferred. Furthermore, in the external preparation for skin in the present invention, the liquid component is preferably transparent or opaque such as an emulsion.
