Description

The present invention is configured so that thin sheets such as tissue paper, wet tissue, dust paper, memo paper, kitchen paper, paper napkin, oil collecting paper, and plastic bags are stored in the box and can be easily taken out. The present invention relates to a sheet storage box that can be transformed into a bottom-up state by deforming the storage box so that there is no hindrance to sequentially removing the sheets even when the number of stored sheets decreases. .

Conventionally, a variety of products in storage boxes containing sheets that can be stored easily in a box made of paper or similar materials and stored in a box made of paper or the like, and can be easily and continuously removed from the outlet are manufactured, sold, and sold. Has been. The heights of these commercially available sheet storage boxes vary widely from 3 to 12 cm. Among them, when the height of the storage box for sheets is relatively low (3 to 6 cm), the fingertips reach from the time immediately after opening until the use of the sheets, so the ease of taking out the sheets is hardly changed. However, when the height of the storage box for sheets becomes large (6 cm or more), when the amount of sheets stored by use decreases, the distance from the upper outlet to the sheets in the box increases. As a result, the fingertips do not reach and it becomes difficult to take out the sheets. For example, in the case of tissue paper, the folding method has been devised so that it can be continuously removed in a pop-up manner. However, if the amount of tissue paper decreases, it will not be possible to cope with it simply by using the folding method. Pop-ups are impossible, and tissue paper is skewed or biased, making it difficult to remove.

For this reason, various devices have been made in various fields in order to solve such problems. For example,

B) In the double bottom method Japanese Utility Model Laid-Open No. 5-71182, the paper with the tissue paper placed on the cardboard slightly smaller than the bottom of the tissue paper box is placed in the box and the U-shaped sideways. A tissue paper box is described which is configured to have two perforations in the shape and two on the front and back of the tissue paper box in total. This is a double bottom, and the stored cardboard is raised to a bottom state, and the raised bottom state is folded inward and locked. Such a double bottom system is stable because it can raise the entire bottom surface, but it requires an extra material of cardboard that is slightly smaller than the bottom surface.

B) Standing piece system on the bottom surface Japanese Patent Application Laid-Open No. 11-245777 discloses that a notch strut piece and a locking piece that forms a convex shape, or another strut piece is connected to the inside of the box in conjunction with the notch strut piece. There is described a raised bottom box with tissue paper that can be worn on the bottom.

Japanese Utility Model Laid-Open No. 7-15580 describes a raised bottom of a tissue paper box of a system in which two standing plates are raised and fixed with a stop plate. The feature of the present invention is that the top line is a double line, and it is described that the assembly is simple and stable.

Japanese Utility Model Laid-Open No. 8-1578 describes a raised bottom of tissue paper having a structure in which an upright plate and a fixed plate are assembled to form a substantially cross-shaped raised bottom.

The above-mentioned prior art document is an invention and a device of a system in which an upright piece is raised on the bottom surface of a box and a part of tissue paper is taken out and raised near the mouth. All of these are easy to assemble, but only a part of the tissue paper is lifted and supported by the raised bottom. The embodiment is limited and its practicality is not so high. In particular, when the box is moved, vibrated, vertically oriented, or thrown out, there is a possibility that the tissue paper will deviate from a predetermined position where it is lifted and will not be lifted or lifted, making it difficult to take out. Furthermore, there is a drawback that the structure of the raised bottom is not very strong.

C) Separated part push-up method for bottom surface part In Japanese Patent Laid-Open No. 10-167354, as a first invention, a folding line is set at an appropriate position of the bottom part, a separation line is extended from both ends thereof, Are connected at points appropriately separated from the fold line to form a raised bottom, and one engagement portion is provided near the tip of the raised bottom facing the fold line, and a constricted portion is formed at a position appropriately separated from the engagement portion. , By providing the other engaging portion on the overhang portion inevitably formed thereby, when the article to be stored is reduced, push the release line away and engage both engaging portions, There is described a container such as tissue paper, which is characterized by facilitating removal of an article to be stored.

Also, in the same document, as the second invention, two separation lines are provided at the bottom portion at an appropriate interval on the bottom surface portion, and the front portion and the back portion are continuously less than half the height thereof. Originally, a separation line was provided to form a raised bottom, and when the contents to be contained were low, the raised bottom was pushed to form a raised bottom, and the removal of the contents was facilitated. A container is described.

The first and second inventions have the advantage that they can be made into a kind of raised bottom state with a relatively large area by a simple operation, but a large opening is formed at the bottom, and the stored items are easily contaminated or dirty. There are drawbacks. In the first invention and the second invention, the raised bottom is formed by simply pushing the raised bottom. Therefore, when a small pressing force is applied when removing paper from above, the raised bottom is immediately pushed down. In order to return to the original, there was a difficulty that could not fully demonstrate the function of easy removal.

2) Box deformation method In Japanese Patent Application Laid-Open No. 2007-76660, a paper box is formed by folding a piece of thick paper and pasting it with an adhesive. When the remaining amount of paper is low, it is a paper box that can raise the bottom by folding the lower part of the paper box with perforations and press creases. A paper box that can constitute a paper pocket, and further has a paper box provided with an opening for taking out tissue paper on the top surface.

Japanese Utility Model Laid-Open No. 7-9783 discloses a horizontally long cubic tissue paper sheet box in which a paper outlet is formed on the top wall and the front wall and the back wall are formed in a horizontally long rectangle. The shape is convex and the top part passes through the position where the height from the bottom wall is approximately 1/3 of the height of the front wall, and the left and right reach the lower corners of the front and back, or the left and right extensions are the lower corners. When forming one or more valley folds that pass through the corner, and the amount of paper accommodated is reduced by about half, with the bottom wall as the top surface, it is recessed into the paper box with the valley fold as a reference, A tissue paper sheet box characterized in that the bottom wall is deformed into a substantially arch shape when viewed from the front is described.

In both prior art documents, when the amount of stored sheets decreases, the box is deformed to lift the tissue paper stored in a raised bottom state, and there is no problem in taking out the paper. It is what you want to do. However, this method deforms so that the lower part of a beautiful paper box is recessed with a precious horizontal cube, and this gives the impression that a part of the box is crushed, so that the commercial value is reduced in appearance. was there.

Along with the improvement of living environment in recent years, it has been demanded that the quality of sheets to be stored is upgraded and the storage amount is also increased. As described above, when the capacity of the sheets increases and the volume of the box increases, the sheets are initially located near the take-out port and can be easily taken out. And the stored sheets play out or bias the space inside the box, making it difficult to take out. In order to solve such a technical problem, it is desirable to raise the bottom of the box and return the position and posture of the take-out port and the sheets to the original state. Therefore, when raising the bottom of the sheet storage box, firstly, the bottom raising operation can be easily performed without using a tool or the like, and secondly, the bottom raising is not a part of the bottom of the box body, but the entire bottom part. And third, the raised bottom state is stable and can withstand various usage modes, and fourth, the sheet storage box is used in a living room, bedroom, and reception room. Because it is required to be harmonized with other interior furniture, it has a beautiful appearance. Fifth, no extra materials or tools are used.
