[Industrial applications]

 The present invention relates to a split-type container that accommodates a relatively flat plate such as a pizza, is easy to open and close, has high strength, and is easy to use.

[0002]

[Prior art]

 As a conventional delivery container for home-delivered pizza, a piece of cardboard paper is cut out as shown in Fig. 7 (a), bent inward along the fold line indicated by the broken line, and the four sides are raised up. In general, a pizza is placed on the bottom surface (A), the lid (B) is folded by bending, and the pizza is housed inside. Since such a container is usually made of cardboard paper, it has excellent heat insulation and hygroscopicity, so it has an excellent function of maintaining the quality of the pizza immediately after baking inside, and it is also discarded as garbage. Easy to use.

[0003]

[Problems to be solved by the device]

 However, since such a conventional container is in the state of a single plate that has been processed so that it can be easily bent as shown in Fig. 3 (a) before use, it is necessary to bend many points one by one before use. It was very annoying to arrange. Moreover, when the lid is opened when eating the stored pizza, and the bottom of the container is used as it is as a plate and the pizza is directly taken out from the lid, this lid is extremely unpleasant and aesthetically unpleasant.

[0004]

[Means for Solving the Problems]

 As a result of various studies in view of this, the present invention can form a container by a simple procedure for storing pizza, etc., and has sufficient strength during transportation such as delivery and stacking, and the lid can be easily opened. We have developed a split-type container that is aesthetically pleasing when the lid is opened.

That is, one aspect of the present invention is that a top surface and four side surfaces are formed into a truncated pyramid shape with a plate material, and a pair of side surfaces facing each other has an upper lid having lateral slits, and a rectangular elastic member. The plate main body comprises a plate body having four side portions bent upright, and a pair of opposing side edges having a tongue piece outwardly bent and extended at the upper end portion of the pair of side edges. It is characterized in that the tongue piece penetrates through the slit by the elastic force of the plate material and protrudes outward when it is put on the upper cover side and the side surface side of the central part of the upper lid slit part. It is more effective to provide them, and it is also possible to use cardboard paper, cardboard, plastic plate, foamed plastic plate or a composite plate of these as at least the elastic plate material.

According to another aspect of the present invention, the upper surface and the four side surfaces are formed of a plate material into a truncated pyramid shape, and a pair of side surfaces facing each other are provided with upper lids having lateral slits, and a square lid. A container body having four side portions of the plate material bent upright and having a tongue piece bent inward at the upper end of a pair of standing side portions facing each other. The upper edge of the upright side portion is characterized in that the upright side portion having the tongue piece is positioned and covered on the outside of the upper lid, and the tongue piece is fitted into the slit from the outside. It is more effective to form a tab piece that is bent and extended outward on the tongue portion provided on the. Corrugated paper, cardboard, plastic plate, foamed plastic plate or a composite plate of these is preferable as the upper lid and / or plate material.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

Example 1 As shown in FIG. 1, a cardboard board is bent to form a truncated pyramid having four side surfaces (1) extending downward and an upper surface (2), and a pair of opposite side upper ends. A slit (3) is provided laterally in the central portion of the portion, and the upper surface (2) portion and the side surface (1) portion in the center of the slit portion are cut in a semicircular shape to form an upper surface defective portion (4) and a side surface defective portion. The part (5) was formed to produce the upper lid (6). In this embodiment, such a slit (3) has a cutting line (8) along the fold line (7) at the boundary between the upper surface (2) and the side surface (1) of the upper lid as shown in FIG. ) And a circular opening (9) in which the center thereof is cut off in a circular shape, and is bent along the fold line (7).

Next, similarly, a cardboard board is cut out as shown in FIG. 2 (a), the four side portions (10), (10 ') are bent inward along the thin lines in the figure, and are erected on the bottom surface (11). Let Furthermore, a pair of side portions (10 ') (10') facing each other is provided with an inward convex cutting line (8) in the lateral direction, and is folded inward along a fold line (7) indicated by a thin line along the cutting line (8). As a result, as shown in FIG. 2B, a tongue side (12) shorter than the length of the slit (3) extending outward is formed at the upper end of the standing side portion (10 ') to form a container body ( 13) was produced. The size of the container body (13) is such that the container body (B) fits inside when the upper lid (6) is covered.

When the upper lid (6) is put on the container body (13), the standing side (10 ') formed with the tongue (12) and the side surface of the upper lid on which the slit (3) is formed are oriented. Due to the elasticity (indicated by an arrow in FIG. 2 (b)) of the container main body (13) that tries to return to the original bent side portion (10 ') of the container body (13), the tongue piece (12) is covered. Easily penetrates the slit (3) and is projected and locked to the outside to complete the pizza delivery container.

In order to open the upper lid of this container, as shown in FIG. 3, place the tongue pieces (12) (12) projecting outward from both slits of the upper lid (6) on the upper surface defective portion (4) with a finger. This can be easily done by pushing the inner lid (6) while pushing it inward. At this time, the upper surface defective portion (4) and the side surface defective portion (5) make it easier to perform the operation with the finger. Further, since the opened upper lid is completely separated from the container body, the container body can be used as a simple plate when eating the pizza or the like contained therein, which is convenient. Furthermore, the upper lid has a square pyramid shape with an open lower surface, so it has high strength, and the upper lids of the same shape can be nested inside each other one after another, making it easy to store and transport. Moreover, the container body is a much smaller single plate than the conventional one when it is stored or transported, which is also easy to handle. Further, a plastic plate or the like can be used as a material for the upper lid and / or the container body, but since the plastic plate has no air permeability, vapor from food easily collects inside. Therefore, in such a case, it is advisable to form a large number of holes in the plastic plate or to attach a moisture absorbent sheet or the like to the inner surface.

Example 2 As shown in FIG. 4, a corrugated cardboard is folded to form a quadrangular pyramid shape having four side surfaces (1) downwardly spreading and having an upper surface, and a pair of opposite side surfaces. An upper lid (20) having a slit (3) in the lateral direction at the center of the upper end of the was prepared.

Next, the cardboard paper is cut out as shown in FIG. 5 (a), and a pair of side parts which are bent along a thin line in the drawing and face each other are low side parts (21) (21) having a low rising height. ), And the other pair of opposing side parts were erected as high side parts (22) (22). And the container body in which the tongue side (12) is formed by bending inward at the upper ends of the high side parts (22) (22), and at the same time, the knob piece (23) is formed on the outside so that it can be easily picked by a finger. (24) was produced.

When the upper lid (20) is put on the container body (24), the side surface provided with the slit (3) is aligned with the high side (22) side of the container body (24) and Put the lower side (21) (21) of (24) into the upper lid (20), cover the upper side (22) (22) with the upper side (20), and cover the upper lid (20). Next, by holding the tab (23) and pushing the tongue (12) into the slit (12) of the upper lid (20), the upper lid (20) and the container body (24) are assembled as a complete container. The slit (3) is dimensioned so that the tongue (12) is fitted securely and is not easily pulled out due to the elasticity of returning to the original side of the high side (22). Further, (25) in the figure is a notch provided so that the tongue piece (12) does not easily come out of the slit (3).

In order to open the upper lid of such a container, in the container assembled as shown in FIG. 6, the knobs (23) (23) protruding outward from the slits of the upper lid are pulled outward. As a result, the upper lid and the container body are easily separated, so that the upper lid can be easily removed. Also, as in Example 1, the upper lid has high strength, has a small volume during storage / transportation, and the container body can be stored in a small space, and can also be used as a simple plate when eating pizza, which is a contained item. It can be used for both purposes and is useful as a pizza container for delivery and takeaway.
