Description

[Detailed description of the invention] <Technical field> This invention relates to an assembly-type container, and in particular, it is a box-shaped container that is assembled by folding sheet materials. We aim to provide products that are superior, easy to manufacture, and robust.

<Background and prior art> Instead of the conventional folding box containers made of warped wood, etc., folding box-shaped containers have been manufactured by assembling foam sheet materials, which is suitable for mass production and is hygienic and has stable quality. are beginning to become widely used as superior products (for example, see Utility Model Publication No. 46-2359, Utility Model Publication No. 49-44321, etc.).

However, in the case of containers made of the conventional foamed sheet mentioned above, it is possible to produce a container with a beautiful appearance by printing on the surface or laminating a printed film, but the shape of the cut sheet material At the edges, the bubbles of the foam sheet were directly exposed, and the cut edges were not smooth, detracting from the appearance. In particular, if the cut edge of the foam sheet is visible on the top surface of the container, such as the upper end of the side wall, which is visually noticeable like the conventional container mentioned above, it is undesirable for the appearance.
Especially in the case of food storage containers, further improvements have been desired. In addition, the upper edge of the opening of these conventional containers is easily damaged when the stored items are put in and taken out, etc.
There was also room for improvement in terms of strength.

<Purpose> The purpose of this invention is to provide a folding box-like assembly type container that is assembled by folding and forming the conventional sheet materials, which has an excellent external appearance and is easy to manufacture, since the cut edges of the sheet materials do not appear on the top surface of the container, etc. , the purpose is to obtain something solid.

<Configuration> The configuration of this device to achieve the above purpose is as follows:
The whole is made of a synthetic resin foam sheet, and a peripheral side frame is formed around the outer periphery of the rectangular bottom plate by a plurality of side plates that are arranged in a row so that they can be bent via V-shaped bending grooves. , the edge piece is connected to the tip of each side plate via a V-shaped bending groove, and V-shaped bending grooves are also formed at two places in the middle of the edge piece, so that the edge piece can be By bending the side frame inward, the cut end of the foam sheet is prevented from appearing on the upper surface of the circumferential frame, and a square frame having a square space is formed between the edge piece and the circumferential frame. It is characterized in that it is formed into a shape, and a peripheral edge that is thicker than the side plate is formed at the upper part of the peripheral side frame.

<Example> Next, an example of this invention will be illustrated below with reference to the drawings.

The illustrated container is made entirely of a sheet material of an appropriate thickness, in which a non-foamed film F with wood grain or other printing is laminated on both sides of a foamed polystyrene sheet S, and 1 is a bottom plate formed into a rectangular or other rectangular shape; Reference numeral 2 denotes a side plate connected to the outer periphery of each side of the bottom plate 1;
A V-shaped bent groove 10 is cut on the upper surface of the boundary between the side plates 2 and the side plates 2, and both ends 20, 20 of each side plate 2
is cut off diagonally.

Furthermore, an edge piece 3 is connected to the tip of each side plate 2, and there are V-shaped folds at three places in total: between the edge piece 3 and the tip of the side plate 2, and at two places in the middle of the edge piece 3. A curved groove 32 is cut.

Also, the width of the boundary portion is from the side plate 2 to the edge piece 3.
It is tapered so that it becomes narrower toward the side, so that when the edge pieces 3 are bent, which will be described later, adjacent edge pieces 3 can be assembled without buffering each other (the first
(see Figures and Figure 2).

To assemble the container in the unfolded state, first raise the side plates 2 around the bottom plate 1 vertically upward at the V-shaped bending groove 10, butt the oblique ends 20 of each side plate 2,
Each edge piece 3 is joined by means such as adhesive tape, glue, stapling, or heat bonding.
are sequentially bent in these V-shaped bending grooves 32 to form a rectangular frame-shaped circumferential edge a having a space C inside at the upper part of the circumferential frame A, and the container is completed (No. (See Figure 3).

In addition, after each edge piece 3 is folded inside the side plate 2, it is difficult to return upward as it is restrained by each other. Of course, it is also possible to use an adhesive or the like to securely fix the edge piece 3.

In addition to foamed polystyrene sheets, foamed sheets made of homopolymers or copolymers of polyethylene, polypropylene, and other synthetic resins are used as the material for the container. Laminated sheets of non-foamed films, sheets, or papers made of various synthetic resins can also be used. Furthermore, it is preferable to print woodgrain or other prints on the surface of the sheet material to create a beautiful appearance. In addition to the square shape mentioned above, the overall shape of the container is triangular, hexagonal,
It can be implemented in any other rectangular shape, and can also be implemented by appropriately combining a lid on the top of the container.

<Effects> According to the assembled container of this invention constructed as described above, the folded piece connected to the peripheral side frame A is folded inward to the peripheral side frame, and the upper part of the peripheral side frame has a thickness thicker than the side plate 2. Since the peripheral edge a is formed, it gives a unique design effect, and the upper end of the side plate 2 is not exposed on the upper surface of the container opening, and the cut end of the foam sheet material is hidden, so it has a very good appearance. It has a beautiful finish and solves the disadvantages of conventional foam sheet containers, such as the air bubbles in the foam sheet being directly exposed on the top of the container, and the cut edges not being smooth, and making it easier to use with wooden containers. It can give a similar sense of luxury and increase the product value.

Furthermore, by sequentially bending each edge piece 3 in the V-shaped bending groove 32, the thick peripheral edge a is formed into a rectangular frame shape with a space C inside at the upper part of the peripheral frame A. Therefore, the overall strength of the peripheral frame A can be increased, and the reinforcing effect as a foam sheet assembly type container is improved, and since the cut end of the foam sheet is not exposed on the upper surface of the opening, it is possible to prevent cutting powder from falling off from the cut end. It is also less likely to break or chip at the edges, resulting in improved durability during use and excellent hygiene, especially when storing food.

In order to form the peripheral edge a with the above-mentioned thickness,
The edge piece 3 is connected to the tip of each side of the side plate 2, and the edge piece 3 is simply bent inward of the peripheral frame a at the bending groove 32, making assembly easy and efficient. can.

Furthermore, regarding the assembly of the entire container, a side plate 2 is connected to the periphery of the bottom plate 1 via a V-shaped bending groove 10.
It can be easily assembled by simply bending and raising the slanted ends 20 of each side plate 2 and joining them together. Moreover, no cut ends of the foam sheet are exposed at each joint, giving it a beautiful appearance. can do. In addition, since the bottom plate 1, side plate 2, and edge piece 3 are made of a sheet material that is interconnected, it is easy to transport or store in the unfolded state, making it popular for use as an assembly type container made of foam sheets. This means that we can provide something of extremely high practical value that can be further expanded.
