DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic case, and more particularly, to a plastic case suitable for displaying and selling small articles such as cosmetics.

[0002]

2. Description of the Related Art Conventionally, small articles such as cosmetics have been housed in plastic cases for display and sale. However, most of the conventional plastic cases have a square tubular case body with a square or rectangular cross section,
The overall shape was also a rectangular parallelepiped or cube. For this reason, even when exhibited on display shelves for display and sale, the display becomes flat and uniform, and the effect of actively promoting the product is not sufficient.

[0003] Therefore, an object of the present invention is to provide a plastic case having a shape capable of promoting sales of goods by improving a display effect at the time of display and sale.

[0004]

To achieve the above object, a plastic case according to the present invention comprises a cylindrical case body formed by bending a plastic sheet along a folding line, and a side plate opening of the case body. In a plastic case having a pair of lid plates extending from an end and closing both side openings of the case body, the case body has a pentagonal cross section obtained by chamfering one corner of a rectangular cylindrical body having a rectangular cross section. Formed, three side plates located in the chamfer,
It is characterized in that it is formed narrower than the two side plates facing the chamfer.

[0005]

FIG. 1 is an exploded view showing one embodiment of a plastic case of the present invention, FIG. 2 is a perspective view showing a state in which a lid of a plastic case after assembly is opened, and FIG. 3 is a plastic case after assembly. FIG. 4 is a plan view of the case, and FIG. 4 is a front view showing a state where the case body before assembly is folded in a plane.

This plastic case is punched into a predetermined shape, and a single plastic sheet 1 provided with a bending line at a predetermined position is bent in a predetermined direction along the bending line, and a glue margin is adhered. By doing so, it can be assembled in a box shape.

[0007] The plastic sheet 1 is provided with five side plates 11 to 15 for forming a rectangular cylindrical case body 10 having a pentagonal cross section serving as an article storage section by bending lines 21 to 25 for forming a cylindrical body. And adhesive margin pieces 16 are formed in sections, and both ends of the three side plates 11, 12, 14 are opened at both ends of the case body 10 via bending lines 26, 27, 28. Lid plate 17 and inner lid plate 1 which are lid members to be closed
8 and 19 are respectively formed. In addition, cover plate 1
7 is inserted into the insertion piece 17a via a bending line 27a.
Is provided on the side plate 14 side of the side plate 15, and a folding adjustment piece 15 a is provided via a bending line 24 a.

The bending lines 21 to 25 are provided in parallel with each other in a direction crossing the substrate of the rectangular plastic sheet 1 at right angles. The positions of the bending lines are determined by assembling the case body 10. Sometimes a pair of adjacent side plates 1
1, 15 for the other side plates 12, 13, 1
4 is set to be narrow.

[0009] When assembling the case body 10 by folding the plastic sheet 1 provided with the folding lines 21 to 25 at such positions along the folding lines 21 to 25, the adhesive margin 16
A pair of wide side plates 11 and 15 joined via a pair are bent at right angles along a bending line 25, and two side plates 1 connected to the other edges of the side plates 11 and 15 respectively.
2, 14 along the folding lines 21, 24, the side plates 11,
15 and a bending line 2
When the side plates 2 and 23 are bent, the side plates 13 located between the two side plates 12 and 14 are in a state of being arranged obliquely. That is, the side plate 13 is disposed obliquely as if one corner of a rectangular cylinder having a rectangular cross section was straightly chamfered,
As a result, a case main body 10 having a pentagonal cross section including the five side plates 11 to 15 is formed.

The widths of the two wide side plates 11 and 15 are set to be the same or approximately the same, and the widths of the two side plates 12 and 14 connected thereto are set to be the same.
Is set to be 5% to 50%, preferably 20% to 40% shorter than the width dimension of the side plate 12, 14. The side plate 13 located between the side plates 12, 14 connects the edges of the side plates 12, 14 with a plane. Dimensions are set.

Therefore, when the case body 10 is assembled into a rectangular cylindrical shape by bonding the adhesive margin pieces 16, the sectional shape of the side plate 1 is as follows.
One corner of a square or a rectangle corresponding to the width of 1, 15 is 5 to 50% of the width of the side plates 11, 15;
It is preferably a pentagonal shape having a chamfered shape with a cutout size of 20% to 40%.
10 to 80%, preferably 3 to 1, 15 width
The side plate 13 having the width dimension of 0 to 50% is located.

The width of the obliquely disposed side plate 13 can be arbitrarily set according to the size of the case body 10 and the shape of the articles to be stored. It is preferred to have a width dimension. Further, the width dimension of the side plate 13 is such that the side plates 12,
If the width of the side plate 13 is larger than the width of the side plates 12, the width of the side plates 12 and 14 is usually smaller than the width of the side plates 12. It is preferable to keep the dimension or less.

Further, the angle of the side plate 13 is arbitrary,
In the case where the basic shape of the case body 10 is not a square cross section as described above but a rectangular shape, for example, the width of each side plate is appropriately set so that the intersection angle of the side plates 13 with the side plates 12 and 14 can be set. Although it can be set arbitrarily, an angle near 45 degrees is optimal in consideration of the visual effect.

The bending line 24a and the folding adjustment piece 15
“a” is provided for folding the case body 10 before assembly into a planar shape with the adhesive margin pieces 16 adhered.
The position of the bending line 24a is determined by the sum of the width of the side plate 11 bonded via the adhesive margin piece 16 and the width of the side plate 15 from the bending line 25 to the bending line 24a. 12,
13 and 14 and the folding adjustment piece 15a are set at positions where the sum of the width dimensions is equal.

Therefore, as shown in FIG. 4, by folding the bending line 21 and the bending line 24a and folding the adjustment piece 15a of the side plate 15 so as to be flush with the side plate 14, Side plates 11, 15 and side plates 12, 13, 14
And the folding adjustment piece 15a overlaps,
The case body 10 before assembly can be folded flat.

The folding line 24a and the folding adjustment piece 15a can be provided on any side plate, but by providing them at the above-mentioned positions, the width of the folding adjustment piece 15a can be minimized. Can be.

In this embodiment, the cover plate 17 is a pentagon corresponding to the cross-sectional shape of the case
Are formed so as to be able to close both ends of the opening, and the entire opening is opened and closed by a single cover plate 17, and the inner cover plates 18 and 19 are formed to cover about half of the opening. However, the shape of these lid plates (including the inner lid plate) and the side plates on which the lid plates are provided can be arbitrarily set. For example, a cover plate having an appropriate length and shape may be extended from the plurality of side plates and adhered to each other, or the cover plates extending from the plurality of side plates may be engaged with each other. .

The case body 10 having a pentagonal cross section as described above.
The plastic case having the side plate 12 or the side plate 14 faces the front so that the side plate 13 obliquely arranged on the chamfered portion is located at the front when the articles (products) are stored and displayed on the display shelf or the like. , The side plate 12 or the side plate 14 and the side plate 13 that are narrower than the width of the case body 10 can provide a three-dimensional effect, thereby greatly improving the display effect. be able to. Therefore, it is possible to increase the degree of attention of the product and contribute to sales promotion.

[0019]

As described above, according to the plastic case of the present invention, when displayed on a display shelf or the like, a three-dimensional effect can be exhibited and the display effect can be improved, so that the product can be actively appealed. And contribute to sales promotion of products.
