Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a collapsible sealed container with a foldable container body made of a foldable thin plate-like material.

(Prior Art) Collapsible containers made of thin plate materials such as paper have conventionally existed.

However, conventional containers of this type do not have a means for completely and easily sealing the opening, and are not suitable for storing fluid foods such as curry roux for preservation. Furthermore, even if the container is heat resistant, it is impossible to heat the fluid food stored therein. moreover,
It has also been difficult to hygienically store and dispose of waste materials containing liquid components.

(Problem to be solved by the invention) The present invention was made to solve such conventional problems, and its purpose is to completely and reliably seal the opening with an extremely simple operation even in ordinary households. The object of the present invention is to provide a foldable sealed container suitable for storing fluid foods, heating foods, or disposing of waste.

(Means for Solving the Problems) The present invention includes a container body made of a foldable thin plate-like material, and the container body has an opening that is rectangular, that is, square or rectangular when the opening is completely opened. The opening edge includes a pair of opposite horizontal edges and a pair of vertical edges, and the container body has a front thin plate and a back thin plate having each of the horizontal edges at an end. , having a right side thin plate and a left side thin plate having each of the longitudinal edges at an end, the front and back thin plates and each of the right and left side thin plates are connected to each other via a corner fold line, Each of the right and left side thin plates has an intermediate fold line extending from the center of each longitudinal edge toward the opposite end of the longitudinal edge, such that the opening of the container body is folded. When folded,
The front and back sides are arranged so that the intermediate fold line is sandwiched between the front and back sheets, so that the horizontal edges approach each other, and each of the vertical edges is folded in half and moves away from the horizontal edges. Sandwiched between the laminates, and on the outer surface of the front or back lamella, is a first lamella extending approximately parallel to the lateral edge and up to corner crease lines on either side of the lateral edge. A double-sided tape is attached, and at least a second double-sided tape is attached to the outer surface of the outer surface at a location spaced apart from the first double-sided tape and extends substantially parallel to the first double-sided tape to the corner fold lines on both sides of the outer surface. A double-sided tape is affixed to the outer surface of each of the right and left thin plates, and a short strip is provided on the outer surface of each of the right and left thin plates, the short strip continuing from at least each end of the first double-sided tape and extending substantially parallel to the longitudinal edge to the intermediate fold line. It is a foldable sealed container with double-sided tape attached.

(Function) When storing an object, the opening of the container main body is wide open in a rectangular shape. Further, when the opening is closed after storing an object, each vertical edge of the opening is folded in half and the horizontal edges are brought into close contact with each other while being sandwiched between the front and rear thin plates, Next, the upper parts of the front and back plates are folded together so that the first double-sided tape is adhered to the outer surface between the first double-sided tape and the second double-sided tape, and then , of the upper part folded together with the first double-sided tape, the second
The tops of the front and back plates are folded again so that the lateral edges are adhered to the second double-sided tape on the side where the double-sided tape is exposed. At this time, both ends of the longitudinal edges of the right and left side thin plates adhered by the short double-sided tape are also adhered onto the second double-sided tape. As a result of the above, the opening is completely sealed. Note that each double-sided tape is covered with a release paper when it is not in use.

(Example) The present invention will be described below based on an example shown in the drawings.

The foldable sealed container according to the present invention includes a container body 1 made of a foldable thin plate material. As the thin plate material, for example, heat-resistant plastic, paper, aluminum foil, coated paper, etc. are used. Although the opening of the container body 1 is specially constructed as described below in accordance with the present invention, the storage portion of the container body 1 near the bottom may have an arbitrary shape.

That is, the container main body 1 has opening edges that are square, that is, rectangular in this embodiment, when the opening is completely opened, and the opening edges 2 are formed as a pair of opposite lateral edges. long edge 3,4
and a pair of short edges 5 and 6 as vertical edges. Note that when the opening is square, the long edges 3 and 4 and the short edges 5 and 6 have the same length.

The container body 1 also includes a front thin plate 7 and a back thin plate 8 having the long edges 3 and 4 at their ends.
and a right side thin plate 9 and a left side thin plate 10 having the short edges 5 and 6 at their ends. The front and back thin plates 7 and 8 and the right and left side thin plates 9 and 10 are connected to each other via corner fold lines 11, respectively. Further, each of the right and left side thin plates 9, 10 has an intermediate fold line 14, 1 extending from the center of each short edge 5, 6 toward the opposite end 12, 13 of the short edge.
It has 5.

Each intermediate fold line 14, 15 is connected to the container body 1.
When the opening is folded, it is sandwiched between the front thin plate 7 and the back thin plate 8, and in this state, the long edges 3, 4 are brought close to each other, and the short edges 5, 6 are folded in half. It is sandwiched between the front and back thin plates 7, 8 in a state where it is folded up and away from the long edges 7, 8 (see FIG. 4).

Further, on the outer surface of the front thin plate 7 (or the back thin plate 8), at a location close to the long edge 3 thereof, a line extends approximately parallel to the long edge 3 to corner fold lines 11 on both sides of the front thin plate 7. The first double-sided tape 16 is attached, and the first double-sided tape 16 is attached on the outer surface.
A second double-sided tape 17 extending substantially parallel to the first double-sided tape 16 to corner fold lines 11, 11 on both sides of the outer surface at a location spaced apart from the double-sided tape 16;
is attached. Note that it is also possible to similarly attach the third and subsequent double-sided tapes at a distance from each other and approximately parallel to the previous one.

Furthermore, on the outer surfaces of each of the right and left side thin plates 9, 10, there is provided a tape that is continuous from each end of the first and second double-sided tapes 16, 17 and is approximately parallel to the short edges 5, 6 at the middle. Broken line 14,1
Short double-sided tapes 18 and 19 extending up to 5 are attached, respectively. In this case, at least only the short double-sided tape 18 is required, and the others can be omitted.

Next, a method of using the foldable sealed container of the present invention constructed as described above will be explained.

When storing an object, the container main body 1 has a large rectangular opening as shown in FIG. 3.
Further, when the opening is closed after storing an object therein, each short edge 5, 6 of the opening is first folded in half as shown in FIG. The short double-sided tapes 18 and 19 are sandwiched between the front and rear thin plates 7 and 8, respectively.
The right and left side panels 9, 10 are each glued together by the steps, and the long edges 3, 4 are brought into close contact with each other. Next, the upper sides of the front and back thin plates 7 and 8 are placed between the first double-sided tape 16 and the second double-sided tape 17 along the first folding line 20 that coincides with the lower end side of the first double-sided tape 16. is folded over as shown in FIG. 5 so as to be glued in a polymeric manner to the outer surface of the front lamina 7 of the holder. Next, the outermost surface of the upper part folded back together with the first double-sided tape 16 on which the second double-sided tape 17 is exposed (the outer surface of the back thin plate 8)
As shown in FIG.
It is folded along the folding line 21. At this time, the upper sides of the right and left side thin plates 9, 10 that have been bonded by the short double-sided tapes 18, 19 are also folded back onto the outer surfaces and bonded. Therefore, as shown in FIGS. 7A and 7B, the long edges 3 and 4 of the front and back thin plates 7 and 8 are closed with a second double-sided tape 17,
Moreover, each short edge 5, 6 is sealed with short double-sided tape 18, and at the same time, it is closed with a second double-sided tape 17 together with the front and back thin plates 7, 8. As a result of the above, the opening is completely sealed, and therefore the inside of the container body 1 is completely isolated from the outside. In addition,
When the third and subsequent double-sided tapes are pasted on the front thin plate 7, the upper parts of the front and back thin plates 7 and 8 are further folded into a rolled-up state several times to further seal the tape more firmly. Ru. Furthermore, it goes without saying that even if the first and second double-sided tapes 16 and 17 are pasted on the back thin plate 8, they still perform the same function. In addition, each double-sided tape 16, 17, 18, 1
9 is covered with ordinary release paper when it is unused, that is, before the opening is sealed.

(Effects of the invention) As explained above, the container main body of the invention has a structure in which the opening can be easily and reliably sealed with double-sided tape, so it is easy to store fluid items such as foods containing moisture. It can be stored and stored, and the contents will not leak. Furthermore, by making the material of the container body heat-resistant, it becomes possible to heat the fluid food as it is in the stored state. Additionally, it becomes easier to store used items in a sealed state for disposal. Furthermore, since the opening can be widened to a rectangular or square shape, it is easy to take things in and out.
