Sheet storage box

Abstract

A sheet storage box has a sheet-removing opening effectively forming the portion to remove the sheet easily from the opening and a portion to easily catch the sheet wherein, the shape of the rims of the opening of the sheet storage box designed to remove the sheet is formed in such a way that the movement of the sheet is reduced by adequately reducing the spatial area of the opening and the rims of the opening are converted to convex shape smooth curves to smoothly slide the sheet.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a box-shaped sheet storage container to store any kind of dry sheet such as tissue paper, kitchen paper, cooking sheets and vinyl bags by folding back and overlapping each sheet one above the other one by one.[0002]A conventional removing opening of a box-shaped tissue-paper storage box, made of paper and the like, includes: that in which a tissue-paper fixing sheet which is formed of a high polymer such as a plastic and which has a cut for opening at the center is pasted on the opening of the sheet storage box; that which has an excessive gap at the center of the opening and which is line symmetric or point symmetric, without the above-described fixing sheet being pasted at a sheet-removing opening; and that in which projections forming the rims of the opening are protruded to substantially the center of the opening and which prevents smooth removal of the tissue paper.[0003]Furthermore, normally, the tissue paper is...

Benefits of technology

[0090]According to the effect of the preceding paragraph 0070 mentioned above, the sheet can be pulled out smoothly and it can be fixed in such a way that it is difficult for the sheet to fall into the storage box.

[0091]According to the effect of the preceding paragraph 0071 mentioned above, the sheet can be pulled out in such a way that the sheet gets caught in the opening.

[0092]According to the effect of the preceding paragraph 0072 mentioned above, the movement of the sheet can be suppressed as the sheets are prevented from being guided toward an opening not intended.

[0093]According to the effect of the preceding paragraph 0073 mentioned abo

Problems solved by technology

Furthermore, conventionally there are various methods of folding the tissue paper such as a one time folding method or a two time folding method, and the size of each folded side of the tissue paper and the position of the folded line is not always uniform.

Furthermore, if a sharp projection exists at the position near (a-a′), it easily gets caught on a joint line of a newly appearing tissue paper and while pulling out the tissue paper, since the next appearing tissue paper lies over the pulling out tissue paper, if the joint line of the next tissue paper lies on the portion of the pulling out tissue paper where the largest force is applied, the tissue paper can easily fall into the storage box by getting caught.

However, according to a method of fixing or removing the tissue paper illustrated in FIG. 7, as the protruding projection is small with a very sharp curve forming the projection and a position held at the time of pulling out the tissue paper is not always at the center, if the tissue paper is held above the projection, there is a possibility of the paper falling into the storage box due to the joint line of the next appearing tissue paper getting caught on the portion where the projection is overlapped with the portion where the strength is concentrated at the narrow range of the tissue paper.

At the time of removing the sheet, since the paper is drawn by inserting a finger from either the left or right side hole, it is obviously more difficult to take the paper out, because it is not possible to take the paper out evenly from the right or left, than a case where the center and its surrounding area are drawn, and the opening has to be reduced to some extent to fix the sheet, otherwise it is difficult to remove the tissue paper.

However, according to FIG. 9, the tissue paper is fixed by narrowing the moving range but, similar to the preceding FIG. 8, the opening has a shape having the apex of the projection near its center, and the same problem described above occurs.

Furthermore, in conventional sheet storage boxes, the projection is raised by inserting the folded line near the bottom of the projection opposite the apex of the projection but, if the projection is raised, the resistance at the time of removing a sheet is reduced and when a sheet falls into the storage box, it takes quite a bit of effort to pull it out since the projection abuts on the finger and if the shape of the projection is complicated, it requires even greater effort.

However, the form mentioned in Japanese Published Unexamined Patent Application No. 2008-137686 has drawbacks mentioned in the preceding paragraph 0047 hereof wherein, the opening has only single direction inclination with respect to the front side or b
