Abstract

<P>PROBLEM TO BE SOLVED: To provide an easily disposable tissue paper container which has a perforated line or a half-cut portion formed in a peripheral portion or in the vicinity of each adhesive applied location of each flap beforehand, and allows the operator to tear the perforated line or the half-cut portion with power smaller than power for tearing an adhesive portion between both the flaps, to thereby facilitate tearing of the tissue paper container. <P>SOLUTION: The container is set up by inserting tissue paper from an opening for inserting the tissue paper therein, successively folding inner flaps, a lower flap, and an upper flap inward, bonding each inner flap and the lower outer flap together, and the upper outer flap and the lower outer flap or each inner flap together via a hot-melt adhesive or a vinyl acetate adhesive, to thereby block the opening formed in a side surface. Herein the adhesive is partly applied to at least one of the flaps to be bonded together, and the perforated line or the half-cut portion is formed in the peripheral portion or in the external vicinity of the adhesive applied area of the flap, or an area of the opposite flap, corresponding to the adhesive applied area. In this manner the tissue paper container 1 is made easily disposable. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a tissue paper container which can be easily disassembled after use of tissue paper and which can be easily discarded.

A rectangular parallelepiped or cubic paper container used for tissue paper such as facial tissue, toilet paper, and paper towel is bulky as it is after use, and is desirably discarded in a disassembled form.
In order to disassemble, it is necessary to peel off the side flaps fixed with an adhesive such as hot melt. However, since the paper container uses strong container base paper from the aspect of protecting the contents and the side flaps are also relatively firmly adhered, the paper container has high rigidity and cannot be easily disassembled.
For this reason, there exists a thing which gave the crease line to the container side part, or made the perforation to the flap of the side, and made disassembly easy.

  However, conventional crease lines, perforations, etc. have the problems that they cannot be folded well from the crease line, the flap tears in the middle of the perforation, or the container breaks from the perforation before use.

(1) Among the four side surfaces connected from the top surface of the container having the tissue paper outlet, after inserting the tissue paper from the side surface comprising a combination of a pair of left and right inner flaps and a pair of upper and lower outer flaps, The inner flap is folded inward, then the lower flap and the upper flap are folded in this order, and the side opening is closed. The top and bottom outer flaps overlap at the tip.
The side surfaces are closed by joining the left and right inner flaps and the upper and lower outer flaps with hot melt or vinyl acetate adhesive, respectively.
(2) In the present invention, in order to join the inner flap and the outer flap in (1), the adhesive is partially applied to either one of the flaps to be joined. Make a perforation or half-cut at or near the outside.
The perforation or the half cut may be performed by a flap to which an adhesive is applied or a flap to be joined. Further, it may be applied to both flaps.
(3) In the case of perforations, the bond width is 0.2 mm to 1.0 mm, and the ratio of the bond width to the entire circumference to be perforated is 10% or less.
(4) The shape of the perforation or half cut may be a shape that surrounds most of the periphery of the adhesive, such as a circle, an ellipse, a square, or a rhombus.
(5) Furthermore, the application position of the adhesive that joins the upper and lower outer flaps is a position where there is an inner flap. That is, the central portion in the width direction of the upper and lower outer flaps is a portion where the pair of inner flaps do not exist, and the upper and lower flaps are not joined here.

(1) Perforation or half cut in advance or around the adhesive application position of the flap, the perforation or half cut portion with a smaller force than destroying the bonded portion of the flaps during carton disassembly Is destroyed and can be disassembled more easily.
(2) Since the adhesive for flap bonding is always applied between two or more flaps, the perforations for carton disassembly do not appear on the carton surface, and the influence on the container strength is small.
(3) Risk of product defects due to adhesive sticking to tissue paper that sticks out of the joints or scatters during application by not joining the upper and lower and outer flaps where there is no inner flap Can be avoided.
(4) Furthermore, since the upper and lower outer flaps are not joined at least in the center, a slight gap is likely to occur between the upper and lower outer flaps, and the disassembling opening perforation usually provided in the lower outer flap is unnecessary. It becomes.
Thereby, the influence on the container strength is further reduced.

  In the following, the present invention will be described by way of examples shown in the drawings, which are given for illustrative purposes and do not limit the present invention.
