Description

  The present invention relates to a thin paper storage box such as a tissue paper or a paper wiper, and more particularly to a push-up piece provided in the thin paper storage box.

  Generally used thin paper storage box is a structure in which two folded thin papers are stacked and stored as if they are alternately meshed, and the thin paper is pulled out one by one from the take-out opening provided on the top surface of the box. Have In such a thin paper storage box, if the remaining amount of thin paper is reduced during use, the gap between the take-out port on the top of the thin paper storage box and the thin paper laminate remaining on the bottom of the box increases, so the thin paper is taken out from the top. It becomes difficult to pull out from the mouth.

  Therefore, as shown in FIG. 3, there is a conventional one provided with a pair of push-up pieces 2 and 3 that can be cleaved by a perforation or the like on the bottom surface of the thin paper storage box 1. When the remaining amount of the thin paper is reduced, the pushing pieces 2 and 3 are pushed into the box, and the remaining thin paper laminate 5 is pushed up as shown in FIG.

  As shown in FIG. 1 of Patent Document 1, the push-up pieces provided in the thin paper storage box are provided with a set of push-up pieces surrounded by an arc-shaped cut line at the substantially central portion in the longitudinal direction of the bottom plate. There are a structure to be provided, a structure in which a pair of push-up pieces disclosed in Patent Documents 2 and 3 are bent inside a thin paper storage box, and a protruding portion of the push-up piece is engaged and locked.

  However, in the case where the base end of the push-up piece is only supported on the bottom surface of the thin paper storage box as in Patent Document 1, the push-up piece is easily deformed by an external force such as pushing the thin paper laminate, and is stable. Cannot support thin paper laminates.

  In the structure in which the pair of push-up pieces are locked by the protruding portions as in Patent Documents 2 and 3, the push-up pieces support each other, so that the strength can be improved. However, if the strength of the projecting portion of the push-up piece is weak, the projecting portion may be damaged and cannot be locked when the push-up piece is torn or when the push-up piece is to be locked. Also, if the protruding amount of the protruding portion is large, the resistance to external force is improved, but the operation of locking the push-up piece becomes difficult. Conversely, if the protruding amount is small, the locked-up push piece is easily detached. It becomes impossible to stably support the thin paper laminate.

  Further, the thin paper storage box is generally made of thin paperboard. For this reason, if the push-up piece provided on the bottom surface of the thin paper storage box is cleaved and bent inward, the rigidity of the bottom surface of the thin paper storage box formed of thin paperboard decreases, and the force such as pushing in the push-up piece As a result, distortion occurs around the portion where the push-up piece is arranged from the width direction. Therefore, distortion also occurs in the vicinity of the bent portion that becomes the base end of the pair of push-up pieces, and the protrusions are not firmly engaged with each other due to the influence, so that the push-up pieces are easily detached and the thin paper laminate cannot be supported.

It is a general-view figure of the conventional pushing edge. It is a figure which shows the state which pushed up the thin paper laminated body with the pushing-up piece.

  An embodiment of the present invention will be described below with reference to FIGS.

  The thin paper storage box of the present embodiment has a pair of push-up pieces provided on the top surface and provided on the bottom surface so as to be tearable. FIG. 1 is a view showing a pair of push-up pieces 2 and 3 before cleavage of the present embodiment. The push-up pieces 2 and 3 before the tearing have a pair of structures connected by the divided side 4. The pair of push-up pieces 2 and 3 includes a first side 23 and a second side 33 that are parallel to each other, a divided side 4 that connects the adjacent end portions e and f, and a first side 23 and a second side 33. It has a third side 22 and a fourth side 32 that extend in parallel from the other end on the side opposite to the one end e and f, and face each other. In FIG. 1, the third side 22 and the fourth side 32 are provided so as to be substantially orthogonal to the first side 23 and the second side 33. However, as shown in FIG. You may provide so that it may cross | intersect diagonally.

  The first to fourth sides and the divided sides of the pair of push-up pieces 2 and 3 are formed to be cleaved by perforations or the like. Bending lines 31 and 21 are provided on the extended lines of the end portions e and f of the first side 23 and the second side 33 to the end portions of the fourth side 32 and the third side 22, respectively. The raising pieces 2 and 3 are bent with the fold lines 21 and 31 as base ends, respectively. The folding lines 21 and 31 can be formed by grooves or the like.

  As shown in FIG. 1, the divided side 4 includes a straight portion extending from one end e of the first side 23, a straight portion extending from one end f of the second side 33, and an S-shaped portion provided in the center portion. Consists of. In the present invention, the S shape includes an inverted S shape.

  The S-shaped part is a projecting part d projecting in the direction of the fourth side 32 on the one end part e side of the first side 23, and a projecting part projecting in the direction of the third side 22 on the one end part f side of the second side 33. c. Therefore, when the split side 4 is cleaved, the push-up piece 2 has the protrusion d, and the push-up piece 3 has the protrusion c.

  In the present embodiment, the push-up pieces 2 and 3 each have only one arc-shaped projecting portion projecting from the straight portion, so that the strength of the projecting portion is ensured and the projecting portion to be locked is easily identified from the shape. can do. For this reason, it is possible to prevent the protrusion from being damaged when the push-up piece is locked or locking the protrusion at the wrong place. In addition, the angle formed by the portions a and b where the S-shaped portion and the straight portion are continuous is 90 ° or more and less than 180 °, and is not an acute angle, so that the protruding portion is damaged when the push-up piece is torn. Can be prevented.

  In the thin paper storage box of the embodiment, when the remaining amount of thin paper decreases during use, the pair of push-up pieces 2 and 3 in FIG. 2A are pushed into the thin paper storage box 1. By being pushed in, the first to fourth sides and the divided sides are cleaved, and the push-up pieces 2 and 3 are bent in the reverse rotation direction with the folding lines 21 and 31 being the base ends, respectively. The first side 23 of the push-up piece 2 and the second side 33 of the push-up piece 3 become tip portions of the push-up pieces 2 and 3 and push up the thin paper. Then, as shown in FIG. 2 (b), the portion b1 where the S-shaped portion and the linear portion of the push-up piece 2 are continuous, and the portion a2 where the S-shaped portion and the linear portion of the push-up piece 3 are continuous approach each other. Then, the protrusions are engaged with each other and pushed up to the pushing pieces and locked.

  Furthermore, in this embodiment, the operation of locking the push-up piece is easy, and without being affected by distortion of the thin paper storage box and its bottom surface caused by external force applied when the push-up piece is torn and pushed, In order to achieve a structure in which the pair of push-up pieces are firmly locked and can support the thin paper laminate stably, the inclination θ of the straight portion of the divided side 4 with respect to the perpendicular of the first side 23 shown in FIG. It should be 0 ° or more and 45 ° or less, more preferably 15 ° or more and 30 ° or less on the side from which the part protrudes.

  When the inclination θ of the straight line portion is less than 0 °, the base end of the push-up piece is distorted due to a decrease in rigidity of the bottom of the thin paper storage box caused by tearing and pushing the push-up piece. The movement that the raised piece tries to restore is not straight but slightly distorted due to distortion. For this reason, the push-up piece 2 and the push-up piece 3 are not firmly locked and easily come off. If the inclination θ of the straight line portion is 0 ° or more and 45 ° or less, more preferably 15 ° or more and 30 ° or less, the push-up piece 2 and the push-up piece 3 are firmly engaged, and the thin paper laminate is stably provided. Even if the thin paper storage box is used in a horizontal state, the thin paper laminate can be stably supported and the thin paper can be easily pulled out from the take-out port to the end.

  Further, the distance h in the vertical direction from the straight portion of the projecting portion d of the S-shaped portion is set to 1 mm or more and 13 mm or less, more preferably 3 mm or more and 7 mm or less.
