Description

[Detailed Description of the Invention] [Industrial field of application] The present invention can be easily sealed in a paper box or the like after storing the product, and is forcibly opened after being put on a distribution channel and before being sold. The present invention relates to a carton with a tamper-proof lock, which enables the user to directly identify the fact that the lid is covered and to hand over the product to the customer's hand without an accident.

[Prior Art] Conventionally, in order to protect a product or the like contained in a paper box from being taken out without prior permission, a lid is sealed with an adhesive tape or is stopped with a stapler.

[Problems to be solved by the invention] However, in the above-mentioned conventional technique, the adhesive tape is partially peeled off to open the lid, and the internal product is removed or replaced, and then the adhesive tape is used. There is a possibility that tampering such as resealing may occur, and in such a case, it was often possible to carry out the act without leaving a trace of tampering on the appearance of the box body, which was a problem. .

The present invention solves the above-mentioned drawbacks of the prior art, and can be locked and easily sealed simply by inserting the tongue piece provided on the lid into the opening provided on the side surface of the box body. A carton with a tamper-proof lock that is suitable for an automatic packaging machine and can be identified because it can be identified before sale because the trace will be left directly on the lid when the lid is forcibly opened and the product inside is taken out. It is provided.

[Means for Solving the Problem] The present invention relates to a carton with a tamper-proof lock for achieving the above-mentioned object, in which one side of a front plate (1) has a crease (2) to attach a glue piece ( 3) is provided, the bottom plate (5) is provided at the lower part with the folding line (4), the glue piece (7) is further provided continuously with the folding line (6), and the insertion piece (with the folding line (8) is provided at the upper part). A lid plate (10) having 9) is provided, and cut fold lines (11, 12) are cut left and right in the center of the fold line (8).
The left and right notches (13, 14) that are raised slightly above the both ends are provided horizontally, and the notch fold line (15) that connects to the left and right is cut slightly upward and the lock piece (16 ) In series, the left and right cuts (17, 18) of the lock piece (16) and the bottom cut (1
The lock piece (16) is made to hang down in the insertion port (20) opened according to 9), and the side plate (22) is provided on the other side of the front plate (1) with a crease (21). Install the lid plate (25) and the bottom plate (26) with the fold lines (23, 24) on the top and bottom, and further install the back plate (28) with the fold line (27) on the other side. Provide bottom plate (30) with (29) and fold line (31)
The glued pieces (32) are connected with each other, the cut-out ridges (34) are provided on the upper part according to the cut fold lines (33), and the lid plate (36) is further connected via the cut lines (35). , A tongue piece (38) is protruded at the center of the tip with a notch fold (37), and a gluing piece (40) is further provided continuously with a half-fold fold (39), and the back plate (2
8) A side plate (42) is provided on the other side with a folding line (41), and a lid plate (45) and a bottom plate (46) are provided on the top and bottom by folding lines (43, 44). , When assembling, place glue on the surface of the gluing piece (40) and fold it normally with the half cut crease (39), and then fold the bottom plate (26, 46) with the crease (24, 44). Further, fold the bottom plate (5, 30) normally with the fold lines (4, 29), reverse fold the gluing pieces (7, 32) with the fold lines (6, 31), and place the glue on the surface. ) Place the adhesive on the back side of the plate, fold the front plate (1) with the creases (21) and then fold the side plate (42) with the creases (41) to complete the gluing. , Stand up, fold each lid plate (10, 25, 36, 45), insert the insert piece (9), insert the tongue piece (38) into the insert opening (20) and bite with the lock piece (16). It is also made in a box.

[Operation] As a result of the construction of the present invention as described above, the tongue piece (38) protruding from the tip of the lid plate (36) is folded and overlapped with the gluing piece (40) connected to the tongue piece (38). When the thickened tongue piece (38) is inserted into the insertion opening (20) from the outside, the tip of the lock piece (16) slightly tilted and protrudes downward from the cut fold line (15). The part and the folded back tip end of the gluing piece (40) folded on the tongue piece (38) by the half cut fold line (39) mesh with and engage with each other to be in a locked state, thereby completing the sealing.

In addition, the tongue piece (38) and the lid plate (36) have notches (3)
7) is interposed, and a notch fold line (15) is provided on the upper part of the lock piece (16), and notch fold lines are provided on both sides of the notch fold line (15) through the notches (13, 14). (1
1, 12) are provided, when the lid plate (36) is forcibly opened from the above locked state, the tongue piece (38) is pulled downward, so that the notch fold line (37).
A break occurs in the cut folds (11, 12) when the lock piece (16) is pushed upward, so that a cut is generated in the cut folds (11, 12). After the sealing, the cut folds (11, 12, The presence or absence of tampering can be determined by the presence or absence of the break in 37).

In addition, the product is stored in the box, and the tongue piece (3
After locking and sealing 8), the purchaser who purchases the sale product can cut the cut-out ridge (34) by the cut-in fold line (33) and the cut line (35), and the cut fold line (34). The lid plate (3
6) can be separated and can be freely opened and closed by the lid plate (10).

[Embodiment] An embodiment of the present invention will be described in more detail with reference to the drawings.
FIG. 1 shows a blank in a developed state, which is formed by punching out a piece of vinyl chloride plate or paper plate, and a sizing piece (3) is provided on one side of the front plate (1) with a fold line (2). , Bottom plate (5) with fold line (4), and fold line (6)
A sizing piece (7) is continuously provided with, and a lid plate (10) having an inserting piece (9) with a folding line (8) is provided on the upper part, and a left and right cut is made at the center on the folding line (8). Fold lines (11,12)
