Abstract

PROBLEM TO BE SOLVED: To prevent a packaged article from being detached from an opening part of a storage part by interposing a cushioning material between an inner surface of the storage part and the packaged article, and absorbing the variance in dimensions of the packaged article by the cushioning material. SOLUTION: A sheet is wound around a packaged article A, or the packaged article A is inserted from an opening on one side of a storage part 3 and stored in the storage part. The dimension between a bottom surface 13 of an engagement recessed part 12 and an inner surface of a top wall 6 is set to be smaller than the height of the packaged article A. When the packaged article A is stored, a projecting part 9 of a cushioning material 2 is displaced downward to press the packaged article A against a surface opposite thereto, i.e., the inner surface of the top wall 6. Thus, the packaged article A is held by the cushioning material 2 and the top wall in the vertical direction. Even when there is a variance in the height of the packaged article A, the projecting part 9 of the cushioning material 2 is displaced in the vertical direction to absorb the variance in dimension.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging case for accommodating, for example, cosmetics or the like in a storage section for display, and in particular, formed by bending a sheet such as a plastic sheet and opening to the side. The present invention relates to a packaging case having a storage section.

[0002]

2. Description of the Related Art Conventionally, products such as cosmetics are housed in a packaging case formed of a transparent plastic sheet in consideration of display properties at the time of sale. In this type of packaging case, a vertically long sheet is bent in a vertical direction to form a sleeve-shaped housing portion including a front and rear wall, a top wall, and a bottom wall, and the entire side surface of the housing portion is opened. Things.

When a product is inserted from the opening, the product is vertically held between the top wall and the bottom wall and held.

[0004]

As described above, in the above-described conventional packaging case, the relationship between the upper and lower inner dimensions of the storage portion and the height of the product is important from the viewpoint of holding the product.
Since the products have dimensional variations, when the products are small, there is a problem that the products fall out of the opening after being stored.

[0005] Such a problem is largely related to the structure of the packaging case. That is, since the housing portion is formed in the shape of a sleeve and the entire side surface is open, there is no strut at the opening to prevent the product from falling. Therefore, when dimensional variations occur, there is no way to prevent the product from falling.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to prevent an object to be packaged from falling off from an opening of a storage section.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a packaging case according to the present invention has a storage section 3 capable of storing an article to be packaged A therein. In the packaging case 3 having an opening on the side, a cushioning material 2 is provided in the housing portion 3 so as to press and hold the packaged object A against the inner surface on the opposite side. I do.

[0008] When the article to be packaged A is accommodated in the packaging case according to the present invention, the cushion material 2 presses the article to be packaged A toward the inner surface on the opposite side. Due to this pressing force, the packaged object A is sandwiched and held between the cushion material 2 and the inner surface on the opposite side. At this time, the dimensional variation of the article to be packaged A can be absorbed by the cushioning property of the cushion material 2. Therefore, even if the package A has a dimensional variation, the package A can be reliably held.

In particular, by forming the engaging portion 12 which engages with the article A to be packaged on the cushion material 2 as described above, the article A to be packaged can be positioned.
Relative displacement between the cushion member 2 and the cushion member 2 can be prevented, and the cushion member 2 is engaged with the accommodation portion 3 through the engagement means 10 and 11, so that the positional relationship between the cushion member 2 and the accommodation portion 3 is also improved. Since it can be fixed, the article to be packaged A can be held more reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a packaging case according to the present invention will be described below with reference to FIGS. The packaging case according to the present embodiment includes a case body 1 formed of a single band-shaped transparent plastic sheet, and a cushion material 2 having cushioning properties. As the plastic sheet, for example, a sheet made of polyester, polypropylene, or polyvinyl chloride having a thickness of about 0.2 mm to 0.1 mm can be used.

The case main body 1 has a housing portion 3 capable of housing the article to be packaged A, and the housing portion 3 includes front and rear walls 4, 5, a top wall 6, and a bottom wall 7. The case body 1 is
The sheet is formed by bending the sheet in the vertical direction along the folding ruled line formed in the width direction and bonding the overlapping portion 8, and the sleeve-shaped accommodation portion 3 having the entire left and right side surfaces opened. You.

The cushion member 2 is provided on the inner side of the bottom wall 7 of the housing portion 3. The cushion material 2
Is formed from a plastic sheet by molding, and is provided with a convex portion 9 protruding upward. And
The convex portion 9 can be displaced up and down by utilizing the bending of the sheet, and this displacement generates an elastic restoring force, thereby providing cushioning. The seat of the cushion material 2 is thinner than that of the case body 1.

Further, engaging pieces 10, 10 are provided at front and rear ends of the cushion material 2 so as to extend outward.
The two engagement pieces 10 are inserted into the cuts 11 in the front and rear walls 4 and 5, respectively, whereby the cushion material 2 is engaged with the case body 1.

The convex portion 9 is formed with an engaging concave portion 12 (engaging portion) with which the packaged object A is engaged, and the bottom surface 13 of the engaging concave portion 12 contacts the packaged object A. Touch the bottom 13
And the inner surface 6a of the ceiling wall 6 so that the packaged object A can be sandwiched and held vertically. Specifically, the distance between the bottom surface 13 of the engagement recess 12 and the inner surface 6a of the top wall 6 is set slightly smaller than the height of the packaged object A.

In the packaging case having the above structure, a sheet is wrapped around the article to be packaged A, or the article to be packaged A is inserted into the accommodation section 3 through an opening on one side thereof and accommodated therein. At this time, the cushion member 2 can be easily inserted due to the cushioning property. In addition, since the distance between the bottom surface 13 of the engagement recess 12 and the inner surface 6a of the top wall 6 is set to be smaller than the height of the package A, the package A is stored. While the convex portion 9 of the cushion material 2 is displaced downward,
The object to be packaged A is pressed toward the opposing surface, that is, toward the inner surface 6 a of the top wall 6. Therefore, the article to be packaged A is sandwiched and held by the cushion material 2 and the top wall 6 in the vertical direction.
In FIG. 3, a solid line indicates a deformed state of the cushion material 2, and a two-dot broken line indicates a state before the deformation.

Further, even if the height dimension of the packaged object A varies, the dimensional variation is absorbed by the vertical displacement of the convex portion 9 of the cushion material 2. In this way, by interposing the cushion material 2 between the packaged object A and the bottom wall 7, even if the packaged product A has a dimensional variation, it can be reliably held without falling off from the opening.

In addition, the positioning of the article to be packaged A can be performed by the engagement concave portion 12 of the cushion material 2, so that
Not only in the vertical direction, but also in the horizontal relative displacement between the packaged object A and the cushioning material 2, it is possible to further improve the stability. In addition, the engagement piece 10 and the notch 1
1 also determines the positional relationship between the cushion material 2 and the accommodating portion 3, so that the packaged object A, the cushioning material 2, and the case body 1 are integrated, and the packaged object A is more securely held. Can be.

As described above, in the present embodiment, the receiving portion 3 is formed in the shape of a sleeve, and the entire both side surfaces are open and the portions which are in tension are not provided on the sides. The benefits are particularly great.

Although it is possible to integrally form the cushion member 2 and the case body 1 from one sheet,
Since the case body 1 and the cushioning material 2 can be formed from sheets of different thicknesses and materials by being separated as described above, the strength of the case body 1 and the cushioning property of the cushioning material 2 are easily compatible. Can be done.

In the present embodiment, the engaging means is constituted by the engaging piece 10 of the cushion material 2 and the cut 11 of the accommodating portion 3, and the cushion material 2 is connected to the accommodating portion 3 via the engaging means.
However, the engaging means is not limited to this. For example, an engaging protrusion is formed on one of the cushion material 2 and the housing portion 3 and the engaging protrusion is engaged with the other. Is also possible. Further, the cushion material 2 may be fitted between the front and rear walls 4 and 5. Further, the cushion material 2 may be fixed in the housing portion 3 by an adhesive means without providing the engaging means. In any case, by integrating the cushion material 2 into the housing portion 3, it is possible to prevent the cushion material 2 from wobbling, so that the packaged object A can be further stabilized.

In the above embodiment, the cushion material 2
Is provided on the bottom wall 7 side, but may be provided on the top wall 6 side.
Further, for example, the cushion material 2 may be provided on the inner surface side of the front wall 4 or the rear wall 5 so as to hold the packaged object A in the front-rear direction (horizontal direction). It should be noted that the cushioning material 2 is provided on both the top wall 6 and the bottom wall 7 or both the front and rear walls 6 and 7 so that the packaged object A is sandwiched and held between the cushioning materials 2 and 2. It is within the range to do.

Furthermore, in the above-described embodiment, a description has been given of a case in which the left and right side surfaces of the housing portion 3 are open, but one side surface may be open. In any case, the cushion member 2 is provided in the accommodating portion 3 in which the opening through which the package 3 can pass is provided on the side, and the cushion 2 presses the package A toward the inner surface on the opposite side. By doing so, it is possible to reliably prevent the packaged object A from falling off from the opening.

The cushion material 2 may be formed by bending paper or the like, or may be formed from a foam material, in addition to the material formed from the sheet as described above.
