Description

[0001] OPENING AND SHUTTING DEVICE FOR PACKAGE AND PACKAGE COMPRISING THE SAME [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing apparatus for a pack such as a packing pack in which a large amount of mask pack can be stored and used, a packing pack in which a large amount of wet tissues can be stored and used, and the like.

In recent years, a large number of wet tissues or the like are housed in a packed state in a state that a large number of wipes are piled up and taken out to the outside through an outlet. In addition to the wet tissues, several mask packs are stored in a packed state, and they are taken out through an outlet so that they can be taken out one by one.

In the case of a mask pack packing pack or a wet tissue packing pack in which a large number of sheets are accommodated as described above, water or skin-friendly ingredients are contained in the form of moisture, such as mask, cloth or paper, Except when doing so, the evaporation of water should be minimized so that it can be used for a long time.

In the case where the contents inside the package pack are exposed to the outside or there is a path through which the water is leaked in the process of storing them, the moisture inside the package pack is evaporated before the use of a large amount of the contents, A problem that the contents can not be used may occur.

Therefore, there is an attempt to minimize the evaporation of water by attaching an opening / closing sticker covering the upper portion of the packed-cake take-out port or by using a cap made of a plastic material and opening /

However, when the opening / closing sticker is used, the adhesive force of the opening / closing sticker may be deteriorated depending on the frequency of use, or the moisture of the contents may adhere to the adhesive of the opening / closing sticker during use, resulting in deterioration of the adhesive force. The adhesion is deteriorated, and a part of the adhesive is poorly adhered to cause a problem that moisture escapes to the outside.

Further, in the case of a simple plastic cap, the problem that the adhesive force is lowered compared with the opening / closing sticker is somewhat compensated, but there is a problem that the degree of sealing between the inside and the outside of the packaging pack is weak. In order to compensate for this, a mixture of the above two methods has been used, but all of them have basically disadvantages and are insufficient to prevent the leakage of water.

Therefore, in recent years, there has been a demand for studies on opening / closing apparatuses and packing packs for packaging packs, which can minimize the evaporation of moisture while facilitating the use of the packaging packs as described above.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 is a perspective view of an opening and closing apparatus for a pack pack according to an embodiment of the present invention. FIG. 2 is a sectional view taken along line A-A 'of FIG. 1, and FIG. 3 is a plan view of FIG. have. 4 is a plan view of a portion excluding the opening and closing portions. Hereinafter, an opening and closing apparatus for a pack pack according to an embodiment of the present invention will be described with reference to FIGS.

1 to 4, an open / close device for a pack pack includes an open part 100 facing the inside of the packing pack, an upper part facing the outside of the packing pack, A first line (211) located inside the open part (100) and connected to each other and having a thickness thinner than the peripheral thickness of the open part (100), and a second line A lead portion 200 having a handle 212 and a handle 220 protruding upward from a contact point of the first line 211 and the second line 212; And a fixing unit 320 disposed on the opening part 100 or the opening and closing part 400. The fixing part 320 and the fixing part 320 are disposed on the opening part 400. The opening part 400 covers the entire drawing part 100, Includes a pair of pincettes (310) detachable by the unit (320) and positioned in a range covered by the opening / closing part (400) Includes a tweezers (300).

The lower surface of the open portion 100 faces the inside of the packing pack, and the upper surface faces the outside. That is, when the fixed frame 500 to be described later is inserted and fixedly coupled to the inside of the packing pack, the lower part of the open part 100 located inside the fixed frame 500 is covered with the mask pack contained in the packing pack, And the upper side of the open part 100 faces the outside. It is possible to seal the inner receptacles from the outside by the fixed frame 500 and the open portion 100 and to be able to be sealed and drawn out by the lead portion 200. [ In addition, the open part 100 can be easily stored and used by the user together with the opening and closing part 400 while exposing the top surface to the outside.

In other words, the outline line of the upper surface of the open portion 100 may be substantially similar to one surface of the opening / closing portion 400 facing (facing). Therefore, the sealing effect can be maximized when the opening and closing part 400 is closed, or the opening part 100 can be exposed to the outside when the user opens the opening and closing part 400. However, the present invention is not limited thereto, and some modifications are possible in order to add necessary or design elements to those skilled in the art.

Meanwhile, the fixed frame 500 surrounds the open part 100 and is coupled to one side of the packing pack. The fixed frame 500 may have a rectangular shape as shown in FIG. 1, but is not limited thereto, and may be suitably modified as required by those skilled in the art. The fixed frame 500 surrounds the open portion 100 and the height of the fixed frame 500 may be lower than the height of the open portion 100 as shown in FIGS. 1 and 2, the fixed frame 500 and the open part 100 may be stacked while forming different layers. However, at least a part of the open part 100 is not a stacked structure, It can be a missing structure. In addition, the bottom of the lead-out portion 200 may have a structure in which no other structure is laminated.

That is, as will be described later, the lower surface of the drawer 200 is in direct contact with the receptacles contained in the packaging pack, while the upper surface is in direct contact with the outside when the opening and closing part 400 is opened. It can be a removable structure. In order to do this, at least the first line 211 and the second line 212 in the lead-out portion 200 are in the state of a cavity without any structure on the lower surface thereof, .

The lead portion 200 is located inside the open portion 100 and a first line 211 and a second line 212 having a thickness smaller than the peripheral thickness are formed in the lead portion 200, And handle portions 220 and 230 protruded upward from the contact points of the first line 211 and the second line 212. The lower surface of the drawer 200 may directly face the uppermost of the plurality of receptacles contained within the pack. In addition, when the opening / closing part 400 is opened, the top surface of the drawing part 200 may be in direct contact with the outside. As a result, when the user applies force in the upward direction by using the grips 220 and 230 of the drawer 200, the first line 211 and the second line 212, which are thinner in thickness than the peripheral portion, Whereby the inner receptacle can be taken out to the outside.

Preferably, the lead portion 200 may be formed of a thin plastic resin. In addition, the open portion 100 and the lead portion 200 may be integrally formed. In addition, the open portion 100, the lead portion 200, and the fixed frame 500 may all be integrally formed, and all of them may be formed of plastic resin or other polymer resin. As a non-limiting example, the open portion 100, the draw-out portion 200, and the fixed frame 500 may be manufactured by an injection process. In addition, the grips 220 and 230 constituting the drawing unit 200 can be formed of plastic resin or other polymer resin, and can be manufactured at the same time in the injection process of other structures, thereby simplifying the manufacturing process.

On the other hand, the lead-out portion 200 may be formed of a thin plastic resin or a polymer resin, thereby ensuring excellent strength. The plastic resin and the polymer resin can be used for a longer time than the sticker since the shape, properties, and composition of the plastic resin can be remarkably changed compared with the conventional stickers, the initial shape can be maintained, and no separate adhesive is needed. That is, when the user uses the grips 220 and 230 of the drawer 200 at the time of first use, the force is applied in an upward direction, and a part of the drawer is pulled out from the first line 211 and the second line 212 In the case where the packing pack is not used, an inlet for taking out the receptacles inside the packing pack is formed, and a portion of the pulled-out portion remains in its original shape. Therefore, when the packing pack is not used, The evaporation of water can be minimized while facilitating the use of the pack pack.

Since the thickness of the first line 211 and the second line 212 is relatively thin compared to other positions, when the user lifts the handle by applying a force toward the upper direction, the first line (211) 211 and the second line 212, respectively. That is, the first line 211 and the second line 212 may be understood as a guideline to be cut.

In other words, the drawer 200 is formed of a plastic resin or a polymer resin, and an inlet for taking out the receptacles in the pack pack is cut in the direction of the first line 211 and the second line 212, And when the receptacles are withdrawn, the inlet can be lifted towards the top. When the inner packaging pack is not used, the incised inlet portion formed by the first line 211 and the second line 212 can be pushed to the original position by using the grips 220 and 230 or the like , The incised portion can be fitted into the original position, and can be maintained substantially uninvolved. This is possible by the plastic resin or the polymer resin which is solid and does not easily deform in the strength and the shape, and the adhesive and the like are not separately needed compared with the conventional sticker which prevented the leakage of water, It is possible to prevent the outflow of moisture. Also, although it is different from the above, it is possible to prevent the outflow of moisture by the opening / closing part to be described later.

5 is a plan view for describing the first line and the second line of the lead portion in detail in the opening / closing device for a pack pack. Referring to FIG. 5, And a first curved line formed as a curved line at a position distant from a contact point of the first line 211 and the second line 212. The second line 212 includes a second curved line at a position distant from the contact point The curvature radius d2 of the first curved line is greater than the curvature radius d1 of the second curved line and the first curved line is longer than the curved line radius of the second curved line at the contact point Can be featured far.

The first curved line and the second curved line are at a distance from the contact and a substantially straight line is formed at a position adjacent to the contact so that most of the force transferred by the user is used for cutting, So that the incision can be made easily. Further, by controlling the curvature radius d2 of the first curved line and the curvature radius d1 of the second curved line as described above, it is possible to prevent a part of the lead-out portion from being completely cut out, It can serve as a stopper for the draw-out portion.

That is, by the second curved line having a large radius of curvature, the portion of the second line 212 corresponding to the right side of the drawing is relatively easily cut to the end of the second line 212, and the first curved line The first line 211 receives less force to be incised. Although the lengths of the first line 211 and the second line 212 are different from each other, even if the same force is applied, the first line 211 and the second line 212 can be equally cut off . Further, by varying the length and shape (the difference in radius of curvature of the first curved line and the second curved line) on both sides of the first line 211 and the second line 212, the cut- 200, and a part of them can be maintained in a coupled state, so that it is possible to perform the function of a stopper for preventing the permeation of water at a later stage.

Meanwhile, although not shown separately, by way of non-limiting example, the end portion of the second line, which is longer in length, is positioned at the end of the region defining the lead-out portion so as not to be further cut, or at the end of the first line and the second line A separate obstacle for performing a stopper function may be provided to prevent the lead portion from being cut excessively. The obstacle that performs the stopper function may be formed thicker than other areas, or may be formed by inserting a material having high strength.

Although not shown separately, in another embodiment of the present invention, the first and second lines may be formed on both sides of the first line and the second line along the first line and the second line, At least one drying prevention line may be further included. In other words, it may be formed in the inward direction of the draw-out portion which is the drying prevention line, and may be formed in a line manner protruding in the same shape as the first line and the second line along the both sides of the first line and the second line to be cut . When the first line and the second line are cut, the internal receptacles are exposed to the outside to some extent. Such a drying preventing line can be formed to prevent direct water from leaking out to the outside. That is, the outflow of moisture can be minimized. In other words, the drying prevention line protruding toward the inside of the packing pack obstructs the path where moisture moves to the outside, so that moisture can be easily evaporated or discharged.

Referring again to FIGS. 1 to 4, the opening / closing part 400 is coupled to one side of the open part 100 and is openable / closable to cover all of the draw-out part 200. That is, when the opening and closing part 400 is closed, the opening and closing part 400 functions to seal all the areas of the drawing part 200 from the outside. In addition, the opening / closing part 400 may cover the entire upper surface of the open part 100. As a result, it is possible to prevent contamination of the lead portion 200 located inside the open portion 100 from the outside, and also to prevent the pin set portion 300 of the open portion 100 from being contaminated.

The handle is provided for the convenience of the user and opens and closes the opening of the drawer 200 formed by the first line 211 and the second line 212. That is, the user lifts up the container by using the protruding handle to take out the receptacles in the pack, and when the user does not use the receptacle, the user can close the container again.

Fig. 6 is a plan view showing a detail of the handle portion in the opening / closing apparatus for a pack pack, Fig. 7 is a front view of Fig. 6, and Fig. 8 is a right side view of Fig.

6 to 8, the handle has a protrusion 230 protruding upward from a contact point of the first line 211 and the second line 212 and a protrusion 230 protruding upward from the contact of the protrusion 230 220). The protrusion 230 is formed at the contact between the first line 211 and the second line 212 so that when the user first applies a force toward the upper direction to use the pack, So that it can be uniformly cut in the direction of the first line 211 and the second line 212.

The annular portion 220 may extend from one end of the protrusion 230 and may be formed integrally with the protrusion 230 by injection during the manufacturing process. In addition, the protrusion 230 may have some elasticity so that the ring 220 can be partially moved up and down. That is, it is formed of a plastic resin, a polymer resin, or the like, and when the user has some elastic force, the user can hold the finger on the hook 220 and pull out the part of the lead portion 200 in the pulling direction.

The annular portion 220 may be formed in the protruding portion 230 so as to be more effectively cut in the direction of the first line 211 and the second line 212 of the lead portion 200, 2 line 212 are formed. 6 to 8, one end of the loop 220 is connected to the protrusion 230, and the other end of the loop is connected to the first line 211 and the second line 212 can do.

Fig. 9 is a plan view showing in detail the pincette portion of the opening / closing apparatus for a pack.

Referring to FIG. 9, the tweezers 300 may be disposed on the open portion 100 or the opening / closing portion 400. Referring to FIG. The tweezers 300 include a fixing unit 320 and a tweezers 310. The fixing unit 320 functions to fix the tweezers 310 to the opening and closing devices for the packs, The user can easily take out the receptacles in the pack pack one by one. The tweezers 310 allow the user to minimize the contamination of other receptacles by removing only one receptacle that is needed without touching other receptacles that are not in use, It is easier to remove the receptacles one by one. In addition, since the user does not have to carry the tweezers 310 separately by the fixing unit 320, the risk of losing the tweezers 310 can be significantly reduced. Although the clamp unit 320 is formed on the open part 100, the clamp unit 320 may be formed on the opening part 400 as needed. In this case, Lt; / RTI >

For example, the fixing unit 320 of the tweezers 300 includes a first fixing unit and a second fixing unit, which are formed as an elastic body and protrude upward from the open portion 100, And the tweezers 310 can be detached and attached by the first fixing unit 320 and the second fixing unit 320. In this case, the pincette 310 may be inserted or removed from the side of the fixing unit 320, and the pincette 310 may be inserted into or removed from the side of the fixing unit 320. Alternatively, Can be used.

As described above, the tweezers 300 are located between the opening and closing part 400 and the open part 100, and when the user does not use the pack, that is, It can be prevented from being contaminated.

1 to 4, a fixing and holding unit (not shown) which is located at least at one side between the open part 100 and the fixing frame 500 and protrudes upward from the open part 100 and the fixing frame 500, (110). The fixed holding part 110 can more effectively prevent the packing pack from being torn out from the opening / closing device for the pack pack when the packing pack is fixed and coupled by the fixed frame 500. [ In other words, the packing pack 500 is protruded upward from the fixed frame 500 as compared with the case where the packing pack 500 is fixed and coupled only by the fixed frame 500, so that the packing pack can be further supported by a physical force.

In other words, as compared with the case where only the fixed frame 500 is inserted and fixed inside the packing pack, when the fixed frame 500 is inserted and fixed to the fixed holding portion 110 protruding upwardly to the inside of the packing pack, It is possible to more effectively prevent the packing pack from being separated from the opening / closing device for the pack pack. The fixed holding portion 110 has a curved surface in a planar section in the drawing, but the present invention is not limited thereto, and the position and shape of the fixed holding portion 110 can be freely changed by a person skilled in the art if necessary.

In order to more effectively prevent the moisture from flowing out of the open part 100, the open part 100 of the opening / closing device for a pack according to the present invention is characterized in that the open part 100 surrounds the lead part 200 and forms a closed curve, The opening and closing part 400 may further include a second sealing part 410 or 420 formed to be capable of concavo-convex coupling with the first sealing part 240, . By such concave-convex coupling, contaminants can be prevented from entering from the outside, and moisture can be prevented from flowing out or being evaporated. In addition, when the user does not use the pack pack by the uneven coupling, the opening / closing part 400 can be firmly closed.

For a more detailed description, a description will be made with reference to FIGS. 10 and 11. FIG. Fig. 10 is a plan view showing a detail of the second sealing engagement portion in the opening and closing part, and Fig. 11 is a cross-sectional view taken along line B-B 'in Fig.
