Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a paper container constructed using elastic paperboard.

[Technical background of the invention and its problems]

Among well-known paper containers, paper containers for confectionery such as sponge cakes, decoration cakes, or castella cakes are made by placing the cake confectionery inside the container body, fitting a lid with a handle to the container body, They either ran a string between the main body and the lid, or put adhesive tape across the main body and the lid to prevent the lid from being removed, and then held the handle upright and carried it by the handle. Furthermore, when taking out a product from a paper container that has been hung with a string, the string or tape is first removed, the container body and the lid are unfixed, the lid is removed from the main body, and the product stored inside the main body is removed. However, it requires skill to tie strings to the container body and lid while preventing the product stored in the container from losing its shape, and when the fixing means is adhesive tape, it is troublesome to remove it.

Furthermore, because the cakes and confections contained in paper containers come in a variety of sizes, it is necessary to use many paper containers of different sizes, and it is especially difficult to fold paper containers that are cylindrical in shape. Therefore, there was an inconvenience that a large storage space was required.

[Purpose of invention]

Therefore, this idea was developed to provide paper containers that can be stored compactly even if they are cylindrical paper containers, and that have different sizes of storage areas by simply replacing a part of the paper container. .

[Summary of the idea]

The proposed paper container consists of a foldable body, a lid that fits on the top and bottom of the body, and a band that irremovably fixes the top and bottom lids that fit on the body. The lid body is composed of a flat wall that closes the opening of the body and a side wall that overlaps the outer periphery of the body, and a band insertion hole is bored at opposite positions on the outer periphery of the flat plate wall, and the band is inserted from the bottom of the lower lid body. The bands are inserted into the flat plate wall insertion hole and the flat plate wall insertion hole of the upper lid body in sequence, and the band ends are mutually locked above the flat plate wall of the upper lid body, thereby fixing the upper and lower lid bodies irremovably.

[Example of idea]

Next, the structure of the present paper container will be explained based on the drawings of the embodiment. 1 is a foldable body, and the body 1 is formed by overlapping both ends of a band-shaped paperboard P inside and out and pasting them together to form an annular shape. The body 1 is provided with one or two sets of bent portions 1a symmetrically parallel to the opening direction,
It becomes foldable at the bending part 1a. 2 is a lid body that fits on the upper part of the body 1, 2' is a lid body that fits on the lower part of the body 1, and the upper and lower lid bodies 2, 2' have the same structure,
Since both can be inserted into and removed from the body 1, the explanation will be given below using the upper cover 2 as an example.
It consists of a side wall 4 that hangs down from the outer edge of a flat plate wall 3 and fits around the outer periphery of the body 1, and band insertion holes 5 and 15 are symmetrically bored in the outer periphery of the flat plate wall 3. In addition, the lid body 2 is provided with a rib 14 formed by curving the upper end 4a of the side wall inward on the inside of the upper part of the side wall 4, and the outer peripheral part of the flat plate wall 3 is directly attached below the rib 14, or An upward tongue piece 13 is provided on the outer periphery of the flat plate wall 3,
This tongue piece 13 is attached to the inner peripheral side of the side wall upper end 4a to form a rib 14, or the tongue piece 13 of the flat plate wall 3 is folded back to the side wall 4 and the upper end 4a to the inner peripheral side. It is attached to a sander beach to form a lid body 2 consisting of a side wall 4 and a flat plate wall 3. Reference numeral 6 denotes a band that irremovably fixes the upper and lower lid bodies 2, 2' fitted to the body 1. The band 6 has a cross section that is one size smaller than the insertion hole 5 bored in the flat plate wall 3 of the lid body, and has a length L. Approximately (body height h x 2)
Notches 8, 18 are formed at + (insertion hole drilling interval l x 3), have folded portions 6a, 6b formed at several locations on the band 6, and engage and engage with the band tip portions 7, 17 mutually.
, the band middle part 16 is brought into contact with the lower part of the flat plate wall 3' of the lower cover body, the band tip parts 7, 17 are passed through the flat plate wall insertion holes 5, 15 to the outside of the body 1, and then the band intermediate part 16 is brought into contact with the lower part of the flat plate wall 3' of the upper cover body 2. It is inserted into the insertion holes 5 and 15, and the notches 8 and 1 of the tips 7 and 17 are inserted in the upper part of the flat plate wall 3 of the upper lid body 2.
8 are engaged and locked with each other.

Since the paper container of the present invention has the above-mentioned structure, the bodies 1 have the same opening 11 size and different heights h.
Then, several types of bands 6 having different lengths L are formed, and a large number of lid bodies 2 that fit on the body 1 are formed, and the body 1 is folded until it is used.

The proposed paper container is constructed by assembling the lid 2, the body 1, and the band 6. At this time, the body 1 and the band 6 are selected from among several types according to the size of the product to be stored. do. For example, when storing a product with a height of 5 cm, a body 1 with a body height h slightly higher than 5 cm is selected, and a band 6 with a length L corresponding to the body 1 is selected. 2 lids 2,
In order to package a product using the body 1 selected as 2' and the band 6, first the body 1 in the folded state is
is opened in a cylindrical or square tube shape, and its body 1
After fitting the lid body 2' to the bottom of the body 1 to form a bottom, the product is stored in the body 1 from above, or the lid body 2'
The product is placed on top of the bottom, and the body 1 is fitted into the lower lid body 2' from the outer periphery of the product to store it.
Next, the middle part 16 of the band 6 was brought into contact with the lower part of the flat plate wall 3' of the lower cover body, and the tip parts 7, 17 of the band 6 were inserted into the sides of the body 1 through the insertion holes 5, 15 of the flat plate wall 3'. After that, hold the lid 2 above the body 1, insert the band tips 7 and 17 into the flat wall insertion holes 5 and 15 of the upper lid 2, respectively, and fit the upper lid 2 to the upper part of the body 1. Then, the notches 8, 18 of the band tips 7, 17 protruding from the insertion holes 5, 15 are engaged with each other at the upper part of the flat plate wall 3, and the upper and lower lids 2, 2' are fixed irremovably. Although the band 6 may be inserted after fitting the lid 2 to the body 1, the insertion holes 5 and 15 of the lid 2
It is preferable that the band 6 is inserted in advance into the body 1, and the body 1 is fitted onto the lid body 2 through which the band 6 is inserted.

To take out stored products from the paper container of this invention, first release the locking of the band ends 7, 17, release the fixation of the upper and lower lids 2, 2', and then move the upper lid 2 to the body 1.
At the same time, the band 6 inserted through the upper lid body 2 is removed, and then the body 1 is removed upward from the lower lid body 2', and the product is placed on the upper part of the lower lid body 2'. Since it is exposed to the outside, even soft sponge cakes can be taken out easily without losing their shape.

The paper container of the present invention is not limited to the above-mentioned embodiment, and the band 6 which passes through the outside of the body 1 from the lower lid 2' and into the upper lid 2 may also be inserted into the inside of the body 1. The same purpose is achieved, and the body 1, the lid 2, and the band 6 can be made of paperboard P with a resin film F attached or laminated, instead of elastic paperboard. The shapes and structures of the band 2 and the band 6, the means for forming them, etc. can be changed as appropriate as long as they do not go against the gist of the present invention.

[Effect of the invention] Therefore, in the paper container of the present invention, the lids are fitted onto the top and bottom of the body, and the top and bottom lids are fixed with a band so that they cannot be separated, so the body and lid are kept together until use. It can be separated and the body can be folded. As a result, the storage space for paper containers is small, and a large amount of paper containers can be transported and stored at one time. In particular, if several types of bodies with the same opening but different body heights and bands of different lengths are formed, and the bodies and bands according to the size of the stored products are selected and assembled, the stored products can be assembled and configured. A paper container of an appropriate size can be freely constructed. In addition, the fitting of the lid to the body and the means for inserting and locking the band are extremely simple, and the mutually locked ends of the bands serve as handles when carrying the paper container, making it possible to stabilize the paper container. It can also be carried safely in a closed state. Moreover, when taking out the product from the paper container, the body can also be removed, making it very easy to take out the product.The paper container of this invention has practical benefits for packaging not only sponge cakes but also various other products. It is something that plays.
