Commodity antitheft implement

Abstract

An economic commodity antitheft implement that can securely prevent a theft of a commodity, and can reduce the number of magnetic detection tags used for preventing a theft of a commodity. The implement includes a case for receiving a commodity and is formed of a box body and a cover body provided on the box body via a hinge so as to open and close an opening portion of the box body. Parallel arranged fitting grooves are formed when the opening portion of the box body is closed, and the fitting grooves are coupled together by a slider inserted over the entire length of the fitting grooves, keeping the box body and the cover body in a locked state. Unless the slider is drawn out of the fitting grooves, the commodity received in the case is not taken out of the case; therefore, it is possible to prevent commodity theft.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a commodity antitheft implement for a lending service of discs and video tapes recording music and image of CD cassettes, game softwares and the like, and for sales commodities, or various sales commodities such as clothes, accessories, daily necessaries and the like.

2. Description of the Prior Art

In a lending service or sale of the above various sales commodities, it is necessary to take measures for preventing a theft of a commodity.

To give an example, the following method has been employed as a conventional antitheft means. More specifically, as already known, empty cases are arranged and displayed in a shelf of a rental shop, and when a customer takes a displayed empty case of a predetermined rental commodity name out of the shelf and brings it to a counter, a salesperson, who stands by the counter, takes a rental commodity displayed on the empty case out of a storage place, and then, performs a predetermined procedure, and thus, lends the rental commodity to the customer.

In the case where the aforesaid method is employed, the customer does not directly touch the rental commodity with his hand; therefore, it is possible to prevent a theft of a rental commodity.

However, the salesperson selects a rental commodity from the storage place, and must tidily store a great many of rental commodities; for this reason, a remarkable amount of time and labor is necessary. As a result, a problem has arisen such that it is difficult to smoothly perform a lending service, and a wide storage place is required.

On the other hand, a case receiving a rental commodity is displayed on a shelf of a shop, and then, the customer takes a desired rental commodity out of the displayed case and brings it to the counter, and thereafter, performs a rental procedure. By doing so, it is possible to solve the aforesaid problem.

However, the customer directly touches the rental commodity with his hand; for this reason, it is possible to take the rental commodity without permission. As a result, there is a possibility that a theft occurs.

So, in order to prevent a theft of commodity, an antitheft tag having a peculiar ID code is attached to an arbitrary position of rental commodity, and further, a predetermined high frequency electromagnetic field is generated in a gateway of the shop. When the rental commodity goes through the gateway of the shop, a resonance circuit of the ID code resonates so as to transmit a peculiar ID code, and then, the high frequency electromagnetic field modulates, and thereby, a passage of the rental commodity is detected. Then, the salesperson supervises whether the rental commodity has been already lent, or has been taken without permission.

However, in the rental procedure at the counter, unless the above ID code (tag) is shielded by any methods, the following problem arises; more specifically, the rental commodity taken according to the predetermined lending procedure is detected in the same manner as a rental commodity taken without permission.

For this reason, a troublesome work is required to perform a shielding procedure, and in addition, a shield equipment is required; for this reason, there is a problem that a cost greatly increases.

The aforesaid problems are not limited to the above rental commodities, and even if the tag is used for antitheft object commodities of other various articles such as clothes, accessories, daily necessaries and the like, the same problem as above is generated.

OBJECTS OF THE INVENTION

Accordingly, it is an object of the present invention to provide a commodity antitheft implement which can securely prevent theft of a commodity by an extremely simple operation.

Further, another object of the present invention is to provide an economical commodity antitheft implement which has no need to shield the tag because the tag is left at the shop, and can thus reduce usage of tags.

The above and other objects of the present invention will be understood more in detail from the following description with reference to the accompanying drawings showing an illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIG. 1 and FIG. 2 , in an antitheft implement according to a first embodiment of the present invention, a case A is composed of a box body 2 having an opening portion 1 for taking in and out a commodity at its side, and a cover body 4 which is provided at a lower edge side of the box body 2 via a hinge 3 so as to open and close the opening portion 1 .

The box body 2 is formed of a side wall 5 , and a peripheral wall 6 which is projected from each side edge of the side wall 5 to a back side of the side wall 5 . The cover body 4 is formed of a side wall 7 , and a peripheral wall 8 which is projected from side edges other than a lower side of the side wall 7 to a back side of the side wall 7 . A hinge 3 is provided at a connective portion of the lower side of the side wall 7 and the peripheral wall 6 by being subjected to half-cut finishing. A hinge having other structure may be used; for example, the hinge may be molded by using a synthetic resin as a raw material. In this case, the peripheral walls 6 and 8 are partially formed with a notch for preventing a received commodity from being pulled out.

Moreover, fitting grooves 9 and 9 are formed at an upper side opposite to the box body 2 and the hinge 3 of the cover body 4 so as to be arranged in parallel when the cover body 4 closes the opening portion of the box body 2 .

The fitting grooves 9 and 9 arranged in parallel form a part of an L-letter bend wall 10 which is extended from each of the side walls 5 and 7 and has a distal end directed downwardly, and are formed inside the bend wall 10 . A shape of the each fitting groove 9 and 9 may be formed so as to correspond to a shape of a slider being used. The slider will be described later.

The case A is formed in the above manner, and for example, at a rental shop, the case A is in a state in which a rental commodity is received in the box body 2 , and the opening portion 1 is closed by the cover body 4 .

In this case, the fitting grooves 9 and 9 are arranged in parallel as shown in FIG. 2 .

A slider B is used so as to combine the box body 2 and the cover body 4 of the case A into a closed state. As shown in FIG. 3 , the slider B is fitted into the fitting grooves 9 and 9 arranged in parallel along the entire length of the fitting grooves 9 and 9 when the case A is in a closed state, and is formed so as to be freely pulled therefrom and inserted therein.

As described above, the slider B is inserted in a fitted state along the entire length of the fitting grooves 9 and 9 arranged in parallel, and thereby, the closed case A is suppressed from being opened; therefore, it is possible to prevent a theft of a commodity received in the case A displayed on a shelf.

Incidentally, the slider B is pulled out of the fitting grooves 9 and 9 , and thereby, an engagement of the fitting grooves 9 and 9 arranged in parallel and the slider B is released; therefore, the opening portion 1 of the box body 2 closed by the cover body 4 can be opened. However, pulling the slider B out of the displayed case A gives an unfair feeling to the customer; thus, the customer has a hesitation, and thereby, it is possible to prevent a theft of commodity.

In the case of FIG. 3 , the slider B is formed of a pair of side plates 11 and 11 which are abutted against the upper edge portion of the fitting grooves 9 and 9 arranged in parallel and are inserted inside the bend walls 10 and 10 , and a connective plate 12 connecting an intermediate portion between opposing upper and lower faces of both side plates 11 . In the arrangement of the fitting grooves 9 and 9 arranged in parallel, for example, a projected wall arranged in parallel is formed with a groove at its outer side, and the slider B may be fitted into the groove formed on the outer side of both projected walls. Namely, any other forms may be used so long as the inserted slider is fitted into the fitting groove so as to prevent the case from being opened.

A stopper 13 is provided inside the fitting grooves 9 and 9 , and then, the distal end of the inserted slider B is abutted against the stopper 13 so that the slider B is stopped at a fixed position. The stopper 13 may be formed on both the peripheral wall 8 and the bend wall 10 .

In this case, it is preferable that there is a contact resistance such that the slider B slides and does not come off even if the case A is tilted.

FIG. 4 to FIG. 6 show an antitheft implement according to a second embodiment. The slider B of the second embodiment is provided with a blocking means 21 at a side facing the case A or the fitting groove 9 . The blocking means 21 is pushed back when the slider B is inserted, and then, becomes engaged when the insert of the slider B is completed so as to block a pull-out of the slider B. Moreover, the side having the blocking means 21 is provided with a space 23 for inserting an engagement releasing tool 22 of the blocking means 21 .

The blocking means 21 is composed of a blocking portion 24 and a blocking member 25 . The blocking portion 24 is a recess (concave) portion or a through hole formed at one of the peripheral wall 8 and the facing side of the connective plate 12 of the slider B, as seen from FIG. 4 . The blocking member 25 is provided at the other of the peripheral wall 8 and the facing side of the connective plate 12 of the slider B, and is pushed back against a projecting force when the slider B is inserted, and thus, is automatically fitted into the blocking portion 24 when the insert of the slider B is completed. Further, the blocking member 25 prevents the slider B from sliding toward a direction opposite to the inserting direction of the slider B.

As shown in FIG. 5 , the blocking portion 24 is provided at the case A side, and the blocking member 25 is provided at the slider B side. These blocking portion 24 and blocking member 25 are not limited to the above position, and may be provided conversely to each other. Moreover, positional modifications may be effected depending upon a shape of the slider B and the fitting groove 9 . In addition, the blocking member 25 is provided in a manner that the connective plate 12 is formed with a U-shaped slit 26 , and an inside of the slit 26 is projected to the blocking portion 24 side. Further, the blocking member 25 is returned back to the original position by using an elastic force of a synthetic resin molded integrally with the slider B. The blocking member 25 may be provided by attaching another part, and as shown in FIG. 18 , may be molded integrally with the slider B made of a synthetic resin when molding the slider B.

As seen from FIG. 4 , the blocking member 25 is formed with a taper surface portion 27 which extends from a portion connecting with the connective plate 12 toward a free end, and is gradually larger projected into the facing blocking portion 24 side. Whereby it is possible to smoothly insert the slider B, and to smoothly push back the blocking member 25 .

Moreover, the above space 23 uses a space surrounded by the connective plate 12 and both side plates 11 . The space 23 may be formed like a groove depending upon a shape of the slider B and an arrangement and position of the fitting groove 9 .

With the construction of the second embodiment, the slider B is inserted into the fitting grooves 9 and 9 arranged in parallel in a fitted state, and thereby, it is possible to prevent the case A from being opened.

In this case, when the slider B is inserted, the blocking member 25 abutting against the peripheral wall 8 is pushed back, and when the insert of the slider B is completed, the free end of the blocking member 25 is engaged with the blocking portion 24 . Thus, the pushing back of the blocking member 25 by the peripheral wall 8 is released, so that the blocking member 25 is returned back to the original position; therefore, the free end of the blocking member 25 can be fitted into the blocking portion 24 as shown in FIG. 6 .

The above engagement prevents the slider B from being pulled out of the case A by a third person, so that the case A can not be opened, whereby it is possible to prevent a theft of a commodity received in the case A.

As seen from FIG. 4 , two blocking means 21 are arranged front and rear; however, the number of the blocking means 21 may be freely determined.

An engagement releasing tool 22 inserted into the space 23 for releasing an engagement of the above blocking means 21 is as shown in FIG. 9 , FIG. 10 and FIG. 11 . The engagement releasing tool 22 is composed of a plate-like portion 31 , a longer piece portion 32 and a shorter piece portion 33 which are arranged in parallel. More specifically, the plate-like portion is inserted into the space 23 , the longer piece portion 32 extends continuously from the plate-like portion 31 toward the front side, and pushes back the ahead-side blocking member 25 so that the blocking member 25 is released from the blocking portion 24 , and the shorter piece portion 33 pushes back the rear-side blocking member 25 so that the blocking member 25 is released from the blocking portion 24 .

In this case, as shown in FIG. 10 , the longer piece portion 32 is bent by a guide 34 projecting from the slider B so as to be guided to a center on the lower side of the ahead-side blocking member 25 , and then, the distal end of the longer piece portion 32 is guided to a center on the lower surface of the ahead-side blocking member 25 by a guide member 35 downwardly projecting from one side edge of the blocking member 25 .

On the other hand, the shorter piece portion 33 has a tapered distal end, and is inserted between guide members 36 which are downwardly projecting from both side edges of the blocking member 25 and are arranged in parallel, and thus, is guided to a center on the lower surface of the ahead-side blocking member 25 .

However, the engagement releasing tool 22 is not limited to the above construction, and may be formed by using a sheet of plate in the case where the blocking means 21 is only one.

The blocking portion 24 is not limited to the through hole shown, and may be formed into a recess portion, or as shown in FIG. 19 and FIG. 20 , may be formed into a protrusion projecting from the upper surface of the peripheral wall 8 having the space 23 .

In this case, when the engagement releasing tool 22 is inserted, a consideration should be given such that each insert distal end of the longer and shorter piece portions 32 and 33 do not collide with each other.

In FIG. 10 , a reference numeral 37 denotes an insert stopper of the engagement releasing tool 22 .

According to a third embodiment of the present invention, as shown in FIG. 12 , an antitheft tag 41 is attached to a desired position of the slider B in order to prevent a commodity from being unfairly taken out of a shop.

The tag 41 is detected (sensed) by an already known magnetic coil, that is, a detecting means such as a magnetic sensor arranged on a gateway of the shop.

As seen from FIG. 12 , the side of the slider B is formed with a recess (concave) portion 42 at its side surface, and the above tag 41 is fitted in the recess portion and is fixed thereto by a bonding (adhesive) agent or the like. The attaching position and means are not limited to the above manner.

Of course, as shown in FIG. 21 , the fitting grooves 9 arranged in parallel are provided along the entire length of the side edge of the case A, and also, the slider B is elongated so as to correspond to the entire length of the fitting groove, and thus, the tag 41 may be attached to a portion elongating the insert distal end side of the slider B.

With the above construction, in the case of selling and lending a commodity, the slider B is pulled out of the case A so as to be left at a shop side, and thereby, there is no need of directly attaching a tag to a case and a commodity; therefore, it is possible to achieve a cost reduction.

According to a fourth embodiment of the present invention, as shown in FIG. 13 , an insert distal end of the slider B is provided with a breaking-through pointed portion 51 .

The above pointed portion 51 is formed into a V-letter shape, and besides, as shown in FIG. 22 , may be formed into a pointed portion 51 having a shape of plus driver.

In short, as shown in FIG. 14 , the pointed portion 51 breaks through a packaging film such as a thermally shrinkable film for packaging the case A so that the slider B is inserted into the fitting grooves arranged in parallel.

By doing so, even in the case where the case A is packaged by a film 52 , it is possible to insert the slider B into the case A which is in a packaged state.

As shown in FIG. 22 and FIG. 23 , the fitting groves 9 and 9 arranged in parallel are formed with a notch portion 71 at the end portion where the slider B is inserted, and thereby, even in the case where a broken piece of the packaging film 52 broken through by the pointed portion 51 is pushed into the case A by the slider B, the pushed broken piece is received in the notch 71 . Therefore, no hindrance is given to a smooth insert of the slider B.

According to a fifth embodiment of the present invention, as shown FIG. 9 , FIG. 13 and FIG. 15 and FIG. 11 , FIG. 16 , and FIG. 17 , an engagement means 61 is provided on a surface where the slider B and the inserted releasing tool 22 overlap with each other.

In the engagement means 61 , the slider B is formed with a recess (concave) portion 62 , and the releasing tool 22 is formed with a tapered protrusion 63 . The tapered protrusion 63 has a greatly projected portion in a drawing direction so as to be fitted in and engaged with the recess portion 62 when the releasing tool 22 is inserted. As shown in FIG. 15 , the recess portion 62 and the tapered protrusion 63 are engaged with each other, and thereby, an engagement is performed. There are the following methods; more specifically, one is a method such that the slider B is drawn out simultaneously when drawing out the releasing tool 22 while slightly lifting it up. The other is the following method; more specifically, a recess stepped portion 65 is formed on the upper surface of the shorter piece portion 33 , and when the releasing tool 22 is inserted, it is upwardly pushed against a return force by the shorter piece portion 33 , and when the insert of the releasing tool 22 is completed, an elastic portion 66 is engaged with the recess stepped portion 65 , and thereby, an engagement is performed, and thus, the slider B is drawn out together with the releasing tool 22 .

According to a sixth embodiment of the present invention, as shown in FIG. 24 and FIG. 25 , a space 73 is formed between the fitting grooves 9 and 9 arranged in parallel, and then, a fingertip operating portion 74 projected from the inserted slider B is fitted into the space 73 .

Of course, when the slider B is inserted, the fingertip operating portion 74 is fitted into the space 73 , and then, is moved therein; therefore, the space 73 is formed over the entire length of the space or a necessary range.

By doing so, after the slider B and the releasing tool 22 are inserted, as shown in FIG. 24 , a fingertip is pushed against the fingertip operating portion 74 , and then, when moving the fingertip to a direction shown by an arrow of FIG. 24 , that is, a direction of drawing out the slider B while keeping a state in which the fingertip is pushed against the fingertip operating portion 74 , the slider B is slid to a direction of being drawn by a pressing force when pushing the fingertip against the portion 74 in a state of overlapping with the releasing tool 22 .

Therefore, in this example, there is no need of providing the engagement means 61 of the sixth embodiment in the slider B and the releasing tool 22 .

In this case, the fingertip operating portion 74 may be set to have a projection length such that its appearance is beautiful.

Moreover, as shown in FIG. 26 , when the blocking means 21 has an engaged relation at the same time when the slider B is inserted, the elastic member 76 is automatically fitted into and engaged with a blocking portion 75 on one facing portion of the slider B and the peripheral wall 8 , and thus, the slider B is stopped from sliding in an insert direction. Whereby no stopper 13 is required on the case A side.

Of course, the elastic member 76 is pushed when the releasing tool 22 is inserted, and thus, an engagement of the elastic member 76 and the blocking portion 75 is released.

The blocking portion 75 and the elastic member 76 have the same structure as the blocking means 21 ; therefore, the details are omitted.

As described above, according to the first to sixth embodiments, it is possible to prevent a theft of a commodity received in the case. Moreover, an engagement of the blocking means of the slider and the case is released by the releasing tool on the shop side, and the drawn slider is left at the shop side; therefore, it is possible to use the case as a sales or lending case.

Further, the slider is provided with the tag; therefore, it is possible to reduce a time and labor for attaching the tag to both case and commodity, and the slider attached with a tag is left at the shop side, there is no loss of tag in a sale of case and commodity.

Namely, no slider is required for each case. The reason is as follows; more specifically, a case receiving an article (commodity) is delivered from maker side; on the other hand, the slider is provided in only sales shop and rental shop.

Therefore, it is possible to reuse the slider attached with a tag received by the shop side, so that a cost can be reduced.

Further, the slider is provided with a breaking through pointed portion, so that the slider can be inserted so as to breaking through the packaging film of the case.

Further, it is possible to draw out the releasing tool and the slider together by the blocking means provided in the slider and the releasing tool.

Furthermore, it is possible to slide and draw out the releasing tool and the slider together by the fingertip operating portion fitted into the space formed between the fitting grooves arranged in parallel.

According to a seventh embodiment of the present invention, as shown in FIG. 27 to FIG. 40 , a case A for receiving a commodity a is provided with a guide means 102 for inserting a slider B so that the slider B is freely drawn out of the case and inserted into the case.

The case A is arranged and displayed on a shelf at a rental shop in a state in which a video tape of the commodity a is received from an opening portion 101 at a rear face of the case A. The case A may be the following type case in accordance with a commodity received therein; for example, there is a type having a box body and a cover body which is provided on the box body via a hinge so that an opening portion of the box body is opened and closed, and a type in which an upper surface is opened as shown in FIG. 44 .

The guide means 102 has the following two types. More specifically, as shown in FIG. 27 to FIG. 30 , the guide means 102 is provided between an upper surface of the commodity a received in the case A from the opening portion 101 and a lower surface of a top wall 103 of the case A. Moreover, as shown in FIG. 31 and FIG. 32 , a flat rectangular cylinder 104 is overlaid on the upper surface of the top wall 103 of the case A, and then, the overlaid surface is fixed by a fixing means such as a bonding agent, fusion bonding and the like. Besides, the rectangular cylinder 104 is molded integrally with the case A, and the inside of the rectangular cylinder 104 is used as the guide means 102 . In addition, as shown in FIG. 33 and FIG. 34 , a mounting wall 105 is fixed on the lower surface of the top wall 103 by a fixing means such as a bonding agent, fusion bonding and the like, and then, both side edge portions on the lower surface of the mounting wall 105 are formed into a protrusion 106 ; on the other hand, both side edge portions of the slider B are formed into a groove 107 , and thus, the protrusion is fitted into the groove, and thereby, the guide means is performed. As shown in FIG. 35 and FIG. 36 , a mounting wall 105 is fixed on the lower surface of the top wall 103 of the case A by the same fixing means as above, and then, the upper surface side of the mounting wall 105 is formed into protrusion 106 ; on the other hand, both side edge portions of the slider B are formed into a groove 107 , and thus, the protrusion is fitted into the groove, and thereby, the guide means is performed. Although illustration is omitted, an L-letter parallel groove member or H-letter guide member is provided on the top wall 103 , and a member such as an L-letter parallel groove member or H-letter guide member is provided on the top wall 103 .

In short, the guide means 102 may be any other form so long as the slider B is freely drawn out and inserted into the case.

A blocking means C is provided on a surface where the case A or the guide means 102 and the slider B face each other. The blocking means C is pushed back when the slider B is inserted, and has an engagement when the insert of the slider B is completed, so as to block the draw-out and insert of the slider B.

As shown in FIG. 27 to FIG. 30 , the blocking means C is composed of a recess-like blocking portion 111 whose lower surface is opened in the top wall 103 side of the case A, and a blocking member 112 whose free end is directed to a direction opposite to the insert direction of the slider B.

The blocking portion 111 is formed into the recess (concave) shape, and besides, may be formed into a through hole as shown in FIG. 42 and may be formed into a protrusion as shown in FIG. 43 . On the other hand, the blocking member 112 is formed in a manner that the slider B is formed with a U-letter slit 113 , and an inside of the slit 113 is lifted up. A lower end of the blocking member 112 formed independently may be fixed on the slider B by a fixing means such as bonding, fusion bonding, iron.

As shown in FIG. 27 to FIG. 34 , the blocking portion 111 is provided on the guide means 102 side, and the blocking member 112 is provided on the slider B side. Of course, as shown in FIG. 35 and FIG. 36 , the blocking member 112 may be provided on the guide means 102 side, and the blocking portion 111 is provided on the slider B side.

In the case where a wall thickness of the top wall 103 of the case A is thin, or in there case where there is a problem in workability, a working plate 114 of the blocking means C is stuck to the lower surface of the top wall 103 by a proper fixing means, or as shown in FIG. 34 , the mounting plate 105 is attached to the rectangular cylinder 104 wall shown in FIG. 31 and FIG. 32 . Moreover, as shown in FIG. 37 , a wall thickness of the top wall 103 of the case A is thickened more than that of other walls, or as shown in FIG. 38 , the top wall of the case A is formed into a double wall, and further, the inside top wall is formed with a through hole blocking portion 111 .

The slider B is positioned to an insert stop position by a proper stopper 115 .

The stopper 115 functions as a stopper in a manner as shown FIG. 29 . The insert distal end of the slider B collides with the front wall of the case A, and besides, a closed wall on the end face of the rectangular cylinder 104 may be used, or as shown in FIG. 25 and FIG. 36 , a projected portion of the edge of the mounting wall 31 may be used.

A space for inserting an engagement releasing tool D of the blocking means C is formed between opposite surfaces of the blocking means C.

As shown in FIG. 39 and FIG. 40 , an obstacle portion 117 is formed in the space 116 ; for this reason, the engagement releasing tool D is provided with a fork-like longer piece portion 119 and shorter piece portion 120 so that the engagement releasing tool D does not collide with the obstacle portion 117 . The longer piece portion 119 releases an engagement of the depth side blocking means C of rear and front two blocking means C, and the shorter piece portion 120 releases an engagement of the inlet side blocking means C of them.

The free end of each blocking member 112 is formed like a fork, and each blocking member 112 is formed with a guide portion 121 which projects in a direction opposite to the blocking portion 111 . The above engagement releasing tool D releases an engagement in the following manner that when each pointed portion 122 of the longer and shorter piece portions 119 and 120 runs on the guide portion 121 , the blocking member 112 is pushed back against a projecting force, and then, the free end of the blocking member 112 is released from the blocking portion 111 .

Moreover, the slider B is attached with the antitheft tag 41 having a peculiar ID code.

In an antitheft implement according to a seventh embodiment, a commodity a is received in the case A, and the slider B is inserted into the guide means 102 .

In this case, when the slider B is inserted, the blocking member 112 of the blocking means C is pushed back by the guide means 102 , and then, when the insert of the slider B is completed, the blocking member 112 and the blocking portion 111 are engaged with each other. Therefore, the blocking member 112 thus pushed back is fitted into the blocking portion 111 , and thereby, the blocking portion 111 and the blocking member 112 are automatically engaged as shown in FIG. 29 and FIG. 36 , so that the slider B can be blocked from being drawn out of the guide means 102 .

By doing so, in the case where the case A receiving a commodity a is taken out of a shop, a theft of the commodity is detected by the tag 41 attached to the slider B.

In the case of selling a commodity a, a salesperson inserts the engagement releasing tool D into the space 116 .

When the engagement releasing tool D is inserted, each pointed portion 122 of the longer and shorter piece portions 119 and 120 runs on the guide member 121 , and then, when the insert of the engagement releasing tool D is continued, the blocking member 112 is pushed; therefore, as shown in FIG. 30 , the blocking member 112 is released from the blocking portion 111 , and thus, the engagement is released.

For this reason, when drawing out the engagement releasing tool D, the slider B is simultaneously drawn out, and then, the slider B thus drawn out is left at a shop side.

In a rental shop, it is possible to perform a lending service of the commodity a together with the case A, and in a shop, it is possible to sell the commodity a together with the case A.

By using a contact pressure of the surface where the engagement releasing tool D and the slider B overlap with each other, the blocking member 112 is pushed so that the draw-out of the slider B is permitted. When the insert of the engagement releasing tool D is completed, the engagement releasing tool D and the slider B overlap with each other by a proper means, or a hooking means may be provided on a surface where they face.

A shape of the engagement releasing tool D is formed into a forked shape in accordance with an arrangement of the blocking means C; however, the shape is not limited to a forked shape.

The slider is fitted into an outer side of the guide rails, and thus, a locking state is kept.

By doing so, when the slider 270 is inserted, the cover body 264 is hesitated to be opened; therefore, this serves to perform an antitheft effect. Moreover, as the eleventh embodiment, the slider 270 is provided with the tag 41 , and thereby, in the case where a commodity is taken out of a shop, a theft of a commodity is detected by the tag 41 . In addition, like the eleventh embodiment, the blocking means and the method of releasing an engagement of the blocking means by the releasing tool are employed, and thereby, it is possible to further improve an antitheft effect.

In order to prevent a fingertip from being caught, a chamfered portion 272 is provided on each corner of both side edges having no hinge 263 and guide rails 269 of at least one of the box body 262 and the cover body 264 .

The above chamfered portion 272 may be provided on one of the box body 262 and the cover body 264 shown in FIG. 77 , and is not limited to both of them.

By doing so, it is possible to prevent a received commodity from being taken out; more specifically, even if a person pushes his fingertip against both corner edges of the cover body 264 and the box body 262 , and then, pulls the box body 262 and the cover body 264 to a mutually reverse direction, the fingertip slips by the chamfered portion 272 ; for this reason, the cover body 264 and the box body 262 are not forcibly opened. Namely, in the case where no chamfered portion is provided on the corner edge, as shown in FIG. 82 , the fingertip is caught onto the corner edge of the cover body and the box body.

As described above, in the antitheft implement according to the eleventh to seventeenth embodiments, in the case where the commodity is taken out of a shop, the commodity thus taken out is detected by the insert member, the slider and the tag of the fitting member, and thereby, it is possible to prevent a theft of the antitheft object commodity.

In selling, the insert member attached with the tag, the slider and the fitting member are removed, and then, are left at a shop side; therefore, these members can be reused, and there is no need of attaching a tag for each commodity, and shielding the tag.

Further, the insert member attached with the tag, the slider and the fitting member are not removed in places other than the shop unless the blocking means and the releasing tool are used; therefore, it is possible to further improve an antitheft effect.

Furthermore, the chamfered portions prevent the case from being forcibly opened; therefore, it is possible to prevent the commodity from being taken out of the case.
