Description

  The present invention relates to a tamper-evident prevention case that prevents a product stored in a packaging box from being pulled out or replaced, and that can be immediately identified if there is an opening act.

  Conventionally, in packaging boxes that contain products, in order to prevent mischief such as product extraction and replacement at the time of distribution and exhibition sales, in order to be able to confirm this immediately when opened. In addition, there are some examples in which a seal is pasted between the main body and the lid. However, the cost of the seal and the labor cost for attaching it increase the cost of the packaging box. The packaging box is being automated as much as possible, but it is difficult to automate the process of attaching small stickers one by one. A large capital investment is required.

  In view of such a situation, the applicant of the present application has developed an unauthorized opening prevention case X as shown in FIG. 1 (Patent Document 1). In this tamper-evident prevention case X, the first to fourth side wall pieces 1, 2, 3, 4 and the adhesive margin piece 5 are connected to each other via folding lines a, b, c, d, and the side wall pieces 1 are connected to each other. , 2, 3 and 4 have bottom flaps H, I, J and K at the lower ends and lid flaps O, P, Q and R at the upper ends, and folding lines h, i, j and k and folding lines o and p, respectively. , Q, r between the fold lines o, q of the inner lid flaps O, Q on the side walls facing each other and the fold lines p, r of the outer lid flaps P, R on the other side walls facing each other. A slit t that is provided with a minute step z, spreads toward the side wall piece 4 so as to straddle the folding line r of the flap R that is folded first, and that connects the ends on the lid flap side, of the outer lid flap. The length of the lid flap P that is formed and folded later is the length that reaches the fold line r provided with the slit t. , Continuously provided the insertion piece S via a folding line s to the end, is provided with a cut portion u so as to straddle the fold line s from both ends of the insertion piece S.

  As shown in FIG. 2, the tamper-resistant case X has a structure in which the lid flap P is fitted and killed. To open the case, the tear zipper v provided on the fold line s side of the lid flap R must be torn. Can not do it. Accordingly, in order to remove or replace the product stored in the unauthorized opening prevention case X, the tearing zipper v must be torn, so that when an unauthorized opening operation is performed, it is immediately determined.

However, when the insertion piece S of the lid flap P is inserted into the slit t, if the insertion of the insertion piece S into the slit t is insufficient, as shown in FIG. In some cases, the insertion piece S is caught in the slit t (shown in black in FIG. 4), and the insertion piece S cannot be locked in the slit t. In this case, even if it seems that the insertion piece S is inserted into the slit t at first glance and the lid flap P has a fitting structure, the insertion piece S and the slit t are not engaged or insufficient. For this reason, the insertion piece S can be removed from the slit t, and even if unauthorized opening occurs, it cannot be detected. Particularly, as shown in FIG. 4, since the size of the catching portion is small, such an insufficient insertion cannot be judged at a glance, and the confirmation work is difficult. Further, in order to prevent such insufficient insertion, it is necessary to confirm complete insertion, and there is a problem that the assembling work of the tamper-evident prevention case becomes complicated.

  The present invention has been made in view of such conventional problems. A main object of the present invention is to provide a tamper-evident case that can be securely inserted by inserting an insertion piece into a slit.

  In order to achieve the above-described object, the present invention provides a body type tamper-evident case 10 including a body box 11 having an opening on one side and a lid 13 for closing the opening 12 of the body box 11. The continuous portion 14 and the lid 13 are connected to either the body box 11 or the lid 13 via the continuous portion 14, and project from the continuous portion 14 in the left-right direction and forward. The body box 11 or the lid 13 in which the insertion piece 16 including the insertion portion 15 is provided and the other insertion piece 16 is not provided is provided with a slit portion 17 into which the insertion piece 16 is inserted. The slit portion 17 has an end edge 18 bent in a U-shape, and both side end edges 19 of the insertion portion 15 are located on the side of the connecting portion 14 related to the insertion portion 15. It is curved or bent convexly in front of the edge 20 The features.

  In the tamper-evident case of the present invention, the width W1 between the side edges 19 of the insertion part 15 is wider than the width W2 between the rear edges 20.

  Furthermore, in the unauthorized opening prevention case of the present invention, the insertion portion 15 is chamfered from the side edge 19 to the rear edge 20.

  In the tamper-evident prevention case of the present invention, the insertion portion 15 is formed in a reverse taper shape from the side edge 19 to the rear edge 20.

  Furthermore, in the tamper-evident prevention case of the present invention, the opening width W3 of the slit portion 17 is formed to be larger than the width W1 between the side edges 19 of the insertion portion 15.

  Moreover, in the structure of the tamper-evident prevention case of the present invention, the insertion piece can be easily inserted into the slit portion by forming the opening width of the slit portion larger than the width between both side edges of the insertion portion. In other words, in the past, the insertion piece is made larger than the opening of the slit portion to make it difficult to remove. However, this makes the insertion into the slit portion difficult, so the workability is poor and the case is wrinkled. There was also. On the other hand, the workability of the insertion work can be improved by enlarging the slit portion, and the dropout of the insertion piece can be effectively prevented by the shape of the side edge, and the workability is improved while improving the reliability. Can do.

  Furthermore, in the structure of the tamper-evident prevention case of the present invention, the workability of the insertion work of the insertion piece into the slit portion can be improved by forming a convex portion at the center of the slit portion.

  Moreover, in the structure of the unauthorized opening prevention case of this invention, an insertion piece can be easily bend | folded by a connection part by giving a half cut process to a connection part.

  In addition, in the structure of the tamper-evident case of the present invention, a zipper is connected to the slit portion, and the zipper is broken at the time of opening, so that the engagement state between the insertion piece and the slit portion can be easily released, and the opening operation Becomes simple, and it can be confirmed at a glance whether or not the zipper has been opened by breaking.
