Description

  The present invention relates to a holder for holding a wound tape of an adhesive tape called a so-called double-sided tape.

  The wound tape of the adhesive tape is formed by winding a belt-shaped adhesive tape on the surface of the strip-shaped release paper in a ring shape, and this wound tape of the adhesive tape is cut to a predetermined length. For convenience, it is generally attached rotatably to a holder having a blade body.

  By the way, in this holder, when the holder body that rotatably supports the winding tape is formed of a plastic material as in the past or the blade body is formed of a metal material, when the holder is disposed of after use, Incineration cannot be performed, and it is also necessary to separate the holder body and the blade body at the time of disposal.

  Therefore, the applicant of the present application tried to develop a holder body and a holder formed from paper that can be incinerated, but the blade body is specially different from the holder body formed from general cardboard in terms of its function. Therefore, it is necessary to assemble the blade body separately formed on the holder body.

As a method of assembling the blade body to the holder main body, a method of adhering the blade body to a predetermined position of the holder main body with an adhesive is conceivable, but the assembling method with the adhesive requires labor.

And a pair of engagement holes with which engagement protrusions provided on both sides of the blade body can be engaged are provided in the overlap piece. Border with polymer fragments , Said spout for protruding the blade portion of the blade body to the outside is provided, wherein the free end of the polymerization pieces, regulations for regulating the movement in the direction of entering and leaving from the spout of the blade body A piece is integrally formed so as to be foldable, and the blade is interposed between the superposed piece and the restricting piece that is folded so as to overlap the inner surface of the superposed piece. Fold the blades together so that they overlap the inner surfaces of the connecting wall and the left and right opposing walls, and bend the left and right opposing walls about 90 degrees with respect to the connecting walls, so that both sides of the overlapping piece are substantially U-shaped. By bending, the engagement protrusion is engaged with the engagement hole, and the blade portion of the blade body is protruded outside the protrusion.

  According to the first aspect of the present invention, the engaging protrusion is engaged with the engaging hole by setting the blade body at a predetermined position of the holder main body, folding the overlapped piece, and assembling the holder main body appropriately. In this way, the blade body is assembled to the holder main body, and the blade body is not inadvertently detached from the holder main body without using an adhesive.

  The holder 1 shown in the figure is for a winding tape T (generally referred to as a double-sided tape) formed by winding an adhesive tape with release paper in a ring shape, and this holder 1 rotates the winding tape T. It comprises a holder main body 2 for supporting it and a blade body 3 used when cutting the wound tape T into a predetermined length.

  The holder body 2 is made of cardboard, and is used to connect a pair of left and right opposing wall portions 4a and 4b along the left and right side portions of the winding tape T, and to connect these left and right opposing wall portions 4a and 4b with a predetermined gap therebetween. A strip-shaped connecting wall 4c is provided.

  The upper and lower support portions 5a and 5b for connecting the left and right opposing wall portions 4a and 4b to support the winding tape T between the opposite left and right opposing wall portions 4a and 4b are opposed to the left and right sides. A holding portion 6 for connecting and holding the walls 4a and 4b with a predetermined interval is provided, and the left and right opposing wall portions 4a and 4b are connected by the upper support portion 5a and the lower support portion 5b and the holding portion 6. It is like that.

  Specifically, the upper support portion 5a and the lower support portion 5b are each formed integrally with the first support pieces 51a and 51b, the second support pieces 52a and 52b, and the tips of the first support pieces 51a and 51b. Thus, it is composed of insertion pieces 53a and 53b which are inserted into insertion holes 54a and 54b described later.

  The first support piece 51a of the upper support portion 5a and the second support piece 52b of the lower support portion 5b are integrally formed on the inner periphery of the through hole 41a provided in the center of the opposing wall portion 4a so as to be opposed to each other. The second support piece 52a of the part 5a and the first support piece 51b of the lower support part 5b are integrally formed in an opposing manner on the inner peripheral edge of the through hole 41b provided in the center of the opposed wall part 4b. 54b is formed in the boundary of opposing wall part 4a * 4b and each 2nd support piece 52a * 52b.

  The holding portion 6 is also composed of a first holding piece 61, a second holding piece 62, and an insertion piece 63 that is integrally formed at the tip of the first holding piece 61 and is inserted into an insertion hole 64 described later. The first holding piece 61 is integrally formed near the connecting wall portion 4c at the outer peripheral edge of the opposing wall portion 2b, and the second holding piece 62 is integrally formed near the connecting wall portion 4c at the outer peripheral edge of the opposing wall portion 2a. The insertion hole 64 is formed at the boundary between the opposing wall 2 a and the second holding piece 62.

  Further, at one end of the connecting wall portion 4c and the left and right opposing wall portions 4a and 4b in the holder body 2, a superposed piece 4d that can be polymerized on the inner wall surfaces of the connecting wall portion 4c and the left and right opposing wall portions 4a and 4b is provided so as to be foldable. At the same time, a rectangular protrusion 41 is provided at the boundary between the overlapping piece 4d, the connecting wall portion 4c, and the overlapping piece so that the blade 31 described later is protruded to the outside.

  A regulating piece 4e for regulating the movement of the blade body 3 in the direction of retreating from the protruding port 41 is integrally formed at the free end of the superposed piece 4d so as to be foldable. A pair of engagement holes 42 into which engagement protrusions 32 of the blade body 3 to be described later can be fitted are provided.

  On the other hand, the blade body 3 is made of a very hard special compressed paper (for example, “Balcanised Fiber” manufactured by Hokuetsu Paper Co., Ltd.), and a substantially serrated blade portion 31 is integrally formed at one end thereof. Engaging protrusions 32 that can be fitted into the aforementioned engaging holes 42 are integrally formed on both sides on the other end side.

  The width W1 of the blade part 31 is substantially the same as the width W2 of the connecting wall part 4c.

  In addition, the line shown with a dotted line in FIG. 1 is a bending line, and each structural member is bent by this bending line.

  In order to assemble the above blade body 3 into the holder body 2, as shown in FIG. 2, the regulating piece 4e of the developed holder body 2 is first folded so as to overlap the inner surface of the superposed piece 4d, and then the blade body 3 is assembled. The blade body 3 is placed on the inner surface of the overlapping piece 4d so that the engaging protrusion 32 faces the engaging hole 42. The other end of the cutting piece 32 is interposed between the restricting piece 4e and the overlapping piece 4d.

  Subsequently, as shown in FIG. 3, the overlapping piece 4 d is folded together with the blade body 3 so as to overlap the inner surfaces of the connecting wall portion 4 c and the left and right opposing wall portions 4 a and 4 b.

  Then, as shown in FIG. 4, after the winding tape T is placed on the inner surface side of one of the opposing wall portions 4a, the first support pieces 51a and 51b, the second support pieces 52a and 52b, and the first and second holding pieces 61 are provided. -62 is bent with respect to the opposing wall portions 2a, 2b, and the insertion pieces 53a, 53b, 63 are bent with respect to the first support pieces 51a, 51b and the second holding piece 61.

  Next, the other opposing wall portion 4b is bent and overlapped on the side surface of the winding tape T, and the first support pieces 51a and 51b are overlapped on the second support pieces 52a and 52b, and then as shown in FIG. Then, the insertion pieces 53 a and 53 b are inserted into the insertion holes 54 a and 54 b, and the first holding piece 61 is also superimposed on the second holding piece 62, and then the insertion piece 63 is inserted into the insertion hole 64.

  Thus, as the left and right opposing wall portions 4a and 4b are bent by approximately 90 degrees with respect to the connecting wall portion 4c, both side portions of the overlapping piece 4d are pushed in by the inner wall surfaces of the left and right opposing wall portions 4a and 4b. When bent into a U-shape, the portion overlapping the connecting wall portion in the overlapping piece 4d is strongly pushed in the direction approaching the inner wall surface of the connecting wall portion 4c, and thereby, into the engagement hole 42 of the overlapping piece 4d. The engaging projections of the blade body 3 are fitted, and the blade body 3 is securely assembled to the holder body 2 so that it does not accidentally fall off the holder body 2.

  The winding tape T loaded in the holder 1 by the above procedure is rotatably supported by the upper support portion 5a and the lower support portion 5b between the left and right opposing wall portions 2a and 2b.
