Description

  The present invention relates to a storage box for sanitary paper such as tissue paper. In particular, the present invention relates to a sanitary paper storage box excellent in demolition property that can be easily separated into paper and plastic film and discarded after peeling off the plastic film attached to the outlet.

  In a storage box for sanitary paper such as tissue paper, a plastic film such as a polyethylene film is usually attached to the inner surface of a take-out port formed on the upper surface (top surface portion) of a rectangular storage box. In recent years, household waste such as storage boxes for sanitary paper such as tissue paper has become necessary to separate paper and packaging plastic films due to increased efforts to reduce waste and recycling containers and packaging. It is desired that the attached plastic film is peeled off after use, separated into paper and plastic film and discarded. In other words, consumers are increasingly required to dispose of different materials. However, in order to dispose of the storage box as paper waste or to recycle it, you must peel off the adhesive parts on the front and rear end faces of the storage box, then put your hands into the cylindrical box and peel off the plastic film. I had to. However, the cylindrical storage box is difficult to access and the work of removing the plastic film affixed to the inside of the box is cumbersome. Therefore, the storage box is often thrown away without peeling off the plastic film.

  On the other hand, in Patent Document 1, a sewing machine is further provided around the perforation provided to form the paper outlet of the tissue paper storage box so that the paper and the plastic film can be easily separated and discarded. A tissue paper storage box has been proposed in which an eye is formed so that the cardboard at the part where the film is adhered can be easily peeled off.

  Further, in Patent Document 2, the two points a and b on the connecting broken line (on the side of the boundary) between the bottom surface part and one side surface part are connected to the bottom surface part as starting points. A cutting line for pushing in a substantially arc shape, or a triangular shape or a polygonal shape is provided, and a cutting line for dismantling is provided from each of the starting points a and b of the cutting line to the terminal end of the continuous folded line of the outer flap. A sanitary paper storage box characterized by this is proposed.

  However, in the case where the perforation is further formed around the perforation provided to form the paper take-out port as in the storage box described in Patent Document 1, the perforation is provided around the take-out port. For this reason, the appearance of the top surface of the storage box is impaired, and the separation perforation may be accidentally broken when the takeout port is formed. In addition, the dismantling of the storage box and the separation work of paper and plastic film must be performed separately, which is troublesome and troublesome. Further, in the case of the storage box described in Patent Document 2, the direction of the force applied when disassembling the bottom surface portion and the direction of the dismantling cut line are vertical (or close to perpendicular), and the dismantling cutting It is difficult to cut and dismantle cleanly along the score line.

Therefore, the object of the present invention is to dismantle the storage box after use and to easily dismantle the storage box so that the inner surface of the box is opened flat, separating it into paper and plastic film and discarding it. It is to provide a storage box for sanitary paper such as tissue paper that can be easily done.
Further, the applicant has filed an application for a sanitary paper storage box in which a tear strip connecting one end of the bottom portion and another end is provided on the bottom portion of the storage box. Although one end or both ends of this peeled piece are provided with push-out cut lines, it is convenient for dismantling, but the strength of the storage box is reduced around the peeled piece in the manufacturing process, especially at high speed. In the manufacturing process, the storage box may be broken or crushed. In addition, there has been a demand for improvement in that it is troublesome to collect the separated pieces.

A first aspect of the present invention that solves the above problems comprises a top surface portion having a sanitary paper take-out port, a bottom surface portion that opposes the top surface portion, and left and right side surface portions that connect the top surface portion and the bottom surface portion. A pair of inner flaps connected to the respective end portions and a pair of outer flaps connected to the respective end portions of the top surface portion and the bottom surface portion. In a rectangular sanitary paper storage box that superposes a pair of outer flaps, a perforation line is formed at one of corners formed by the left and right side surfaces and the bottom surface or top surface, or at two or more corners. A sanitary paper storage box characterized in that it has a connecting portion having a length of 0.8 mm or more and 6 mm or less at both ends of the perforation line provided at the corner portion, and the length of one of the connecting portions. Other It is longer than the length of the connecting part .

The second aspect of the present invention is that the top surface portion having the outlet and the plastic film are bonded with a width of 2 to 5 mm in the longitudinal direction and intermittently with a width of 2 to 5 mm in the short direction. A sanitary paper storage box according to claim 1 or 2.
According to a third aspect of the present invention, the top surface portion having the outlet and the plastic film are bonded along the long side end and the short side end of the plastic film, and are not bonded in the vicinity of the four corners of the plastic film. The sanitary paper storage box according to claim 1 or 2.

According to the above invention, when the empty storage box after use is discarded, the inner surface of the box is easily opened flat by breaking the perforation provided on the bottom surface part and / or the bottom surface part. Can do. In addition, since both ends of the perforation line have connecting portions having a length of 0.8 mm or more and 6 mm or less, the perforation line is not inadvertently broken when the storage box is used. Furthermore, by making the length of one connecting portion longer than the length of the other connecting portion, it is also useful for preventing damage to the storage box by transferring the storage box starting from the longer connecting portion in the manufacturing process. .
Moreover, the adhesion of the plastic film on the top surface portion having the take-out port is 2 to 5 in the longitudinal direction.
By adhering in the width of mm and intermittently adhering in the width direction of 2 to 5 mm, the paper and the plastic film can be easily separated and discarded. Alternatively, the top surface portion having the take-out port and the plastic film are bonded along the long side end and the short side end of the plastic film, and the four corners of the plastic film are non-adhered, so that the four corners of the plastic film are It becomes a knob allowance, and it becomes easy to pick a plastic film, and resistance at the initial stage and at the time of separation is reduced.
