Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional folding line, perforated line, etc., makes neat folding along a folding line impossible, causes a flap to tear in the middle of a perforated line, and leads to the breakage of a container along a perforated line before use of the container. <P>SOLUTION: A tissue paper case easy to scrap is provided. According to the tissue paper case, out of four side faces connected to the case top face having a tissue outlet, two side faces parallel with each other each form an opening through which tissues are inserted. Each of the two side faces is composed of a pair of upper and lower outer flaps which are connected to the top face and the bottom face, respectively, and a pair of inner flaps connected to the other two side faces. Following insertion of tissues, the inner flaps are folded inwardly, and then the lower outer flap and the upper outer flap are folded in sequentially, which causes the upper and lower outer flaps overlap on their front ends to close the opening on the side face. The lower outer flap is provided with a U-shaped or approximate U-shaped breaking perforated line which breaks to make an opening widthwise at the center on the upper edge of the lower outer flap, and the upper outer flap is glued to the lower outer flap at both separate sides of the perforated line to close the opening. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a tissue paper container which can be easily dismantled 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 is made of strong container base paper from the viewpoint 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 exist some which made the disassembly easy by giving a crease line to a container side part, or giving a perforation to a side flap.

JP-A-5-32279 JP2002-29580

  Conventional crease lines, perforations, and the like have problems in that they cannot be folded well from the crease line, the flap is torn in the middle of the perforation, or the container is damaged from the perforation before use.

(1) Of the four side surfaces connected from the top surface of the container having the tissue paper outlet, the two parallel side surfaces of the opening into which the tissue paper is inserted are a pair of connected side surfaces from the other two side surfaces. It consists of a pair of upper and lower outer flaps that are connected to the inner flap and the top or bottom surface. The part is closed. The top and bottom outer flaps overlap at the tip. The side surfaces are joined by closing the inner flap, the upper and lower outer flaps, and the upper and lower outer flaps with hot melt or vinyl acetate adhesive.

(2) In the present invention, in order to break the joint between the upper and lower outer flaps, the lower outer flap is subjected to a perforation for dismantling having a straight or curved corner (U-shape). The position of the perforation is the center in the width direction of the lower outer flap, and the front end in the opening direction coincides with the front end in the height direction of the flap.

(3) The adhesive that joins the upper and lower outer flaps is not applied to the central portion in the width direction of the lower outer flap provided with the disassembling perforation of (2).

(4) In order to join the flaps, the adhesive is partially applied to either one of the flaps to be joined. However, a perforation or a half cut may be applied to the substantially outer periphery of the application part. The perforation or the half cut may be performed by a flap to which an adhesive is applied or a flap of a joining partner. Further, it may be applied to both flaps.

(5) The shape of the perforation or half cut of (4) may be any shape that surrounds most of the periphery of the adhesive, such as a circle, an ellipse, a square, or a rhombus.

(1) Although there have been dismantling perforations on the lower and outer flaps, the shape is trapezoidal + U-shaped, and the adhesive between the upper and lower outer flaps is applied to the inner part surrounded by the perforations. Therefore, even when trying to break the joints of the upper and lower outer flaps from the perforation for dismantling the lower outer flap, the perforation of the trapezoidal part does not break well, and only the central part of the upper and lower outer flaps is broken. It was.

(2) In the present invention, the lower outer flap is provided with a U-shaped perforation for disassembling, or an adhesive for joining the upper and lower outer flaps to the perforated portion. By doing so, the finger force of the dismantle is smoothly transmitted from the perforation of the lower and outer flaps to the center of the upper and outer flaps, and further to the joint of the upper and lower outer flaps, and the joint of the upper and lower outer flaps is destroyed. Is called.

(3) Furthermore, by making a perforation or half cut in advance around the adhesive application position of the flap, the perforation or half cut can be performed with a smaller force than destroying the adhesive portion between the flaps during carton disassembly. The part is destroyed and dismantling is easier.

(4) The area of the perforation applied to the lower and outer flaps is also smaller than before, and the influence on the container strength is improved.

  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.
