Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a container, and particularly relates to a container which does not take up space in a folded state and can be easily assembled from the folded state.

[Prior art and its problems] Generally, in a grocery store or a convenience store,
The products are put in paper bags or plastic bags and handed to customers.

In a bookstore or shoe store, a paper bag with a handle may be used as a storage bag for commodities.

However, in general, paper bags have few handles and it is inconvenient to carry.Some plastic bags have handles. If you carry it with you, it may be broken on the way. In addition, although a paper bag with a handle is often strong in strength and convenient, the paper bag and the handle are separate parts, and it is necessary to fix this with a fastening means such as bonding or binding. For this reason, there is a problem that the production is troublesome and the production cost is expensive.

[Purpose of the present invention] The present invention has been made in view of the above-mentioned conventional problems. When not in use, a large number of products can be stored in a folded state before assembly, and can be assembled immediately before use.
It is an object of the present invention to provide a convenient container that can securely store articles after assembly and can be easily carried by a handle.

According to the present invention, the object has opposite front and rear walls, and the rear wall and the front wall are curved so as to bulge outward from each other. Four bottom surface forming pieces are respectively extended to the wall through fold lines, and the four bottom surface forming pieces of the four bottom surface forming pieces are connected to substantially lower central portions of the front wall and the rear wall. The line of sight is a straight line perpendicular to the boundary between the front wall and the rear wall, and two other bottom surfaces adjacent to the two bottom surface forming pieces and communicating with the boundary between the front wall and the rear wall. The fold line of the piece is an inclined line that gradually rises from both ends of the straight fold line toward the boundary between the front wall and the back wall, and when the four bottom surface forming pieces are folded over each other,
The bottom surface is formed so as to have a substantially inverted V-shape whose center portion, viewed from the side, coincides with the boundary between the front wall and the back wall, and a finger is placed on top of the front wall and the back wall. This is achieved by providing a container characterized by having an opening through which it can be inserted.

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

FIG. 1 is a perspective view showing an embodiment of the container of the present invention, and FIGS. 2 (a), 2 (b) and 2 (c) are a front view, a side view and a bottom view showing the container of this embodiment. is there. Referring to each figure,
The container 1 is formed of, for example, paper or a plastic sheet. The container 1 has two opposing surfaces, namely a front wall 2 and a back wall 3, which are each curved so as to bulge outward. Below the front wall 2 and the rear wall 3, four bottom forming pieces 5,
6, 7, 8 are extended. Then, the bottom surface forming pieces 5 and 6 are bent at the fold line, and then the bottom surface formation pieces 7 and 8 are similarly bent at the fold line.
When viewed from the bottom, as shown in FIG. 2 (c), the bottom forming pieces 5, 6, 7, 8 are folded on each other to form a container bottom. At this time, as shown in FIG. 2 (b), the center of the bottom of the container is the front wall 2 and the rear wall 3
And a substantially inverted V-shape on the side, which coincides with the boundary line of. That is, the fold line is determined so that the shape of the bottom surface of the container is formed as such.

On the other hand, above the container 1, the front wall 2 and the rear wall 3 are close to each other, and the front wall 2
A substantially elliptical opening 4 is formed in both the rear wall 3 and the rear wall 3. The opening 4 is provided so that a finger can be inserted into the opening 4 when the container 1 is used, and the periphery of the opening 4 can serve as a handle.

As described above, the front wall 2 and the rear wall 3 are each curved so as to bulge outward, so that when the container is cut into a circle, the contour of both wall surfaces is exactly the cross-sectional shape of the biconvex lens. looks like.

In using the container 1, the bottom forming piece 5,
6, 7 and 8 are folded inside the container 1, the folded portion is down to serve as a bottom wall, and the opening 4 side is up, and a finger is inserted into the opening 4 to remove the container. Can be carried around.

Further, above the container 1, that is, near the mouth of the container 1,
Instead of fixing the front wall 2 and the rear wall 3 with an adhesive or an adhesive tape, the front wall 2 and the rear wall 3 are simply in contact with each other, so that the opening becomes an openable and closable opening, and articles can be taken in and out from this opening. . The thing stored in the container 1 is preferably, for example, a handkerchief, a tie, or other small items, or a food such as a rice cracker or a cracker.

2 (a), 2 (b) and 2 (c), the front wall 2 and the rear wall 3 are formed in a substantially rectangular shape when viewed from the front.

The sides of the substantially rectangular body in the vertical direction are formed substantially in parallel. The upper side in the lateral direction is formed in an arc shape having a central portion as a vertex, and the opening 4 is provided below the vertex. In addition, the lower side in the horizontal direction is formed by an inclined side that extends inclining from the lower ends of both sides in the vertical direction, and a horizontal side that connects each end of the inclined side.

The side profile (FIG. 2B) has a substantially wedge shape, and its upper side serves as a handle. The lower side is the front wall 2 and the rear wall 3 which open in two directions from the upper side to the lower side.
The bottom connecting the end portions is concavely curved inside the container 1.

The bottom contour shape (FIG. (C)) is formed in a substantially rectangular shape,
The two sides in the longitudinal direction are formed in parallel. Further, the vertical side is curved so as to protrude outward.

Then, the bottom surface forming pieces 5 and 6 connected to the front wall 2 and the rear wall 3 in series are bent and folded into the inside of the container 1 from the bottom side, and the folded bottom surface forming pieces 5 and 6 are folded.
The bottom surface forming pieces 7 and 8 are further covered from above.
Is folded inside the container 1 to form the bottom surface of the container 1.

 FIG. 3 is a development view showing the container of this embodiment.

In FIG. 1, a container 1 is formed from a material such as a piece of paper, a plastic sheet, or the like. A prototype of the container 1 is formed by cutting or punching along the outline of the developed view.

In the unfolded state, the prototype of the container 1 is formed such that the longitudinal sides of the front wall 2 and the rear wall 3 having the maximum area are formed in a straight line, and the front wall 2 and the rear wall 3 are adjacent to each other. I have.

Upper sides of the front wall 2 and the rear wall 3 in the horizontal direction are curved so as to protrude outward. On the other hand, on the lower side, bottom forming pieces 5 and 6 and bottom forming pieces 7 and 8 are formed in series through a fold line. A margin 9 is formed on one side of the front wall 2, and a lower portion of the margin 9 is adhered to a bottom forming side formed on the back wall 3 to form a part of a bottom forming piece. As the role.

The fold line forms a substantially horizontal fold line at the boundary between the front wall 2 and the bottom surface forming piece 5 and at the boundary between the back wall 3 and the bottom surface formation piece 6, and the front wall 2 and the bottom surface The boundary between the forming pieces 7 and 8 and the boundary between the back wall 3 and the bottom forming pieces 7 and 8 gradually approach the ridgeline of the boundary between the front wall 2 and the back wall 3 from both ends of the horizontal fold line. When the container 1 is assembled, the bottom surface of the bottom surface of the container 1 is formed at the center of the front wall 2 and the rear wall, as shown in FIG. 2 (b). It has a substantially inverted V-shape on the side, which coincides with the boundary line with 3, so that the bottom wall can be prevented from opening unnecessarily in conjunction with the weight of the stored items. In addition, a fold line is also formed on the margin 9 in accordance with the fold line formed on the bottom surface forming piece of the back wall 3.

When the front wall 2 and the rear wall 3 are bent along the ridgeline of the boundary between the front wall 2 and the rear wall 3 so that they are opposed to each other, and the margin 9 is attached to the rear wall 3, 4
The container 1 before assembly as shown in the figure is formed.

In assembling and using the container 1 before assembling, the bottom forming pieces 5, 6, 7, and 8 are folded inside the container 1, and then an article (not shown) is accommodated in the container 1 and a finger is inserted into the opening 4. And holding the container 1 in your hand,
The front wall 2 and the rear wall 3 bend inward, whereby a force acts on the bottom surface forming pieces 7 and 8 to enter the inside of the container 1. Therefore, each bottom surface forming piece 5, 6, 7, 8
Does not need to be fixed with an adhesive or the like to sufficiently serve as the bottom surface of the container 1.

Also, since it is possible to assemble without using an adhesive or the like, when not using or preparing the container 1, it is possible to store the container 1 in a folded state without assembling. it can.

[Effects of the Invention] As described in detail above, according to the present invention, the four bottom surface forming pieces are inclined from the edge of the bottom surface toward the center, so that each bottom surface forming piece has an article in the container. When it is inserted, the component force due to gravity (the component force acting in the horizontal direction) acts to push each bottom forming piece downward and press it against the front wall and back wall side. The pressing force acts as a reinforcing force, and the bottoming out is prevented against a remarkably large force as compared with a container having a simply horizontal bottom wall. Further, when the four bottom surface forming pieces are folded on each other, the bottom surface is formed so as to have a substantially inverted V-shape whose center portion, when viewed from the side, coincides with the boundary between the front wall and the rear wall. Therefore, the ridge line formed by the fold line of the two bottom surface forming pieces communicating with the substantially lower central portions of the front wall and the rear wall comes into close contact with the table surface when the container is placed upright on a table or the like. The container can be prevented from tilting to the front side or the back side, and can be stably placed upright. And since it has a simple structure, it can be manufactured very easily. It can be folded and stored when not in use, so it does not require a large space, it can be quickly assembled and used just before use, and a finger is inserted into the opening. Thus, a container which can be easily carried can be provided.
