Description

  The present invention relates to a blister pack of a type having a recess for accommodating a product and slidingly mounting a mount for closing the recess from the back.

  Conventionally, in order to accommodate small household appliances, etc., it consists of a blister cover formed with a recess for accommodating an object to be accommodated, and a mount that closes the recess from the back, and on the back side of the left and right edges of the blister cover Folding flaps are provided that are folded back so as to slidably guide the left and right side edges of the mount, and the back of one of the upper and lower edges of the blister cover is folded back to stop the mount. A stop flap is provided, and after the product is received in the recess and the mount is inserted into the slide flap, staples are driven from the front side to prevent the product from falling off.

However, in such a configuration, it is necessary to fix the mount by stapling in the work of storing the product, and there is a disadvantage that workability is poor.
Therefore, in order to eliminate such drawbacks, the locking flap provided on one of the upper edge or the lower edge, the mount slit formed at the corresponding position, and the locking flap do not come out of the slit. A claw piece and a projection that urges the claw piece in a direction to be surely hooked on the edge of the slit, insert a locking flap into the slit of the mount, and lock the claw piece on the edge of the slit Thus, a technique for preventing the mount from coming off is disclosed (Patent Document 1).
JP 2006-0669604 A

  However, in the technique described in Patent Document 1, the locking flap must be accurately inserted into the slit of the mount, which requires great care. Furthermore, if the nail pieces are not hooked on the edge of the slit of the mount, there will be no effect of retaining them, and extra labor will be required. In such a configuration, the locking flap, the claw pieces, and the protrusions are only slightly deformed, so that it becomes difficult to insert into the slit and hook onto the edge of the slit, resulting in poor durability. Moreover, the mount is composed of two folded sheets only for preventing the claw pieces from appearing on the front side of the mount, and does not contribute to the prevention of slipping out.

  In view of such a problem, an object of the present invention is to provide a blister pack that can improve workability when fixing a mount and at the same time easily obtain a retaining effect.

In order to achieve the above object, the present invention employs the following technical means.
1stly, it consists of the blister cover 3 in which the recessed part 2 which accommodates a to-be-received object was formed, and the mount 4 which plugs up the said recessed part 2 from the back, The back side of the right-and-left both-ends edge of the said blister cover 3 A sliding flap 5 is provided that is folded back so as to slidably guide the left and right side edges, and the mount 4 is configured to be folded in two, thereby forming a paper gap formed at the upper end or the lower end of the mount 4. 6, and a stop flap 7 that is folded back so as to stop the slide of the mount 4 is provided on one back side of the upper end edge or the lower end edge of the blister cover 3. On the other side of the edge, there is provided a locking flap 8 which is inserted into the paper gap 6 by folding back to the back side to prevent the base 4 from coming off from the blister cover 3. The features.

  2ndly, it consists of the blister cover 3 in which the recessed part 2 which accommodates a to-be-contained was formed, and the mount 4 which plugs up the said recessed part 2 from the back surface. A slide flap 5 is provided that is folded back so as to slidably guide the left and right side edges. The mount 4 is folded to form a first paper gap 6a formed at the upper end of the mount 4, and the mount. 2 and a second paper gap 6b formed at the lower end of the blister cover 4, and the blister cover 3 is inserted into the first paper gap 6a and the second paper gap 6b by folding back to the back side at the upper and lower edges, respectively. The upper and lower locking flaps 8 are provided to prevent the mount 4 from coming off from the blister cover 3.

Thirdly, the blister cover 3 has a protruding portion 9 that protrudes downward from the concave portion 2, and the lower surface of the protruding portion 9 is parallel to the horizontal plane. The fold line 10 of the locking flap 8 is located.
As a result, it is possible to relieve the caution of inserting the locking flap 8 and at the same time easily obtain the effect of retaining it, and the function is not lost even for some deformation.
Moreover, the workability at the time of fixing the mount 4 can be improved while omitting the step of forming the stop flap 7, and the retaining effect can be easily obtained.

  Further, since the lower surface of the protruding portion 9 is parallel to the horizontal plane, the blister pack 1 can be erected on the horizontal plane, and the fold line 10 of the locking flap 8 is formed on the rear side edge of the lower surface of the protruding portion 9. Therefore, the locking flap 8 can be easily folded back to the back side.

  According to the present invention, the workability at the time of fixing the mount is improved, and at the same time, the retaining effect can be easily obtained.

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 4, the blister pack 1 includes a blister cover 3 formed with a recess 2 for storing objects such as sundries, tools, cosmetics, and household items, and a mount 4 that closes the recess 2 from the back. Consists of.
The blister cover 3 is made of a resin such as PET or PVC, and has appropriate flexibility. By forming a substantially rectangular resin sheet by vacuum molding, a substantially rectangular parallelepiped recess 2 having a size corresponding to the object to be accommodated is formed at a position slightly below the center of the blister cover 3.

  On the back side of the left and right end edges of the blister cover 3, there are provided sliding flaps 5 that are folded back so as to slidably guide the left and right side edges of the mount 4, and on the back side of the upper end edge of the blister cover 3. Is provided with a stop flap 7 which is folded back so as to stop the slide of the mount 4. Each of the flaps 5 and 7 is fixedly formed on the blister cover 3 by performing a bending process after the recess 2 is vacuum formed and punched. Note that the folded flat plate-like portions of the flaps 5 and 7 have a trapezoidal shape in plan view with the bottom continuous to the front surface of the blister cover 3 and have a shape with a corner near the center of the blister cover 3. . Therefore, the mount 4 can be easily fitted to the flaps 5 and 7.

  At the lower end edge of the blister cover 3, a locking flap 8 that can be freely folded back to the back side through a fold line 10 is provided. The fold line 10 of the latching flap 8 is a perforation, whereby the folding flap 8 can be folded back with a light force. The locking flap 8 is formed together with the perforations by vacuum forming the recess 2 and then punching it. The fold line 10 of the locking flap 8 may be a ruled line, a hinge, or the like. Further, the flat plate-like portion of the locking flap 8 that is folded back is a trapezoidal shape in plan view with the bottom continuous to the front surface of the blister cover 3 and has a shape with a corner near the center of the blister cover 3. Therefore, the locking flap 8 can be easily inserted into the paper gap 6 of the mount 4.

  A plurality of (two) projecting portions 9 projecting downward from the lower surface of the blister cover 3 are formed simultaneously with the recess 2 by vacuum forming. The inside is a small recess communicating with the recess 2. Further, the lower surface of the protruding portion 9 is parallel to the horizontal plane, and the fold line 10 (lower end edge of the blister cover 3) of the locking flap 8 is located on the rear side edge of the lower surface of the protruding portion 9. Therefore, since the lower surface of the protrusion 9 and the lower edge of the blister cover 3 are in the same plane, the blister pack 1 can be brought upright by grounding the lower surface to the ground, and the blister pack 1 can be suspended without being suspended. You can display small household appliances to be housed.

Further, the angle formed between the lower surface of the protruding portion 9 and the locking flap 8 in a state in which the locking flap 8 is folded back to the back side of the blister cover 3 is between the front side of the blister cover 3 and the locking flap 8. It is smaller than the angle formed. Therefore, the stress applied to the fold line 10 can be reduced as compared with the case where the fold line 10 of the locking flap 8 is not positioned on the rear side edge of the lower surface of the protrusion 9. In addition, the locking flap 8 can be folded back with a lighter force, and the durability of the crease 10 is improved.
The mount 4 has an elongated rectangular shape, and is configured as a double-folded one that is continuous at the upper edge, thereby forming a paper gap formed between the front mount 4a and the back mount 4b at the lower end of the mount 4. 6. In addition, when the stop flap 7 is provided in the back side of the lower end edge of the blister cover 3, and the latching flap 8 is provided in the upper end edge of the blister cover 3, the mount 4 is continuous at the lower end edge. A paper gap 6 may be provided at the upper end. In addition, since printing can be performed on the folded inner side of the mount 4, more explanation about the product can be described than the mount 4 composed of a single sheet.

The blister cover 3 has a hanging display hole 11, and the mount 4 has a communication hole 12 that communicates with the hanging display hole 11 when the mount 4 is set on the blister cover 3.

First, the lower end of the back side mount 4b is turned upward, and the locking flap 8 is folded back to the back side. Next, after the free end of the locking flap 8 is inserted into the paper gap 6 between the front mount 4a and the rear mount 4b, the lower end of the rear mount 4b is restored. In this manner, the paper gap 6 of the mount 4 and the locking flap 8 are locked.

Therefore, if the mount 4 further moves upward with the mount 4 set, the movement of the mount 4 is restricted by the stop flap 7, and if the mount 4 moves downward, the mount 4 is moved. The movement is restricted by the locking flap 8. Therefore, the mount 4 is securely engaged with the blister cover 3 to prevent the mount 4 from coming off, which is effective for preventing the product from falling off.
When removing the mount 4 from the blister pack 1, the lower end of the back mount 4b is turned upward, and the free end of the locking flap 8 is formed between the front mount 4a and the back mount 4b. It is only necessary to pull it out from 6.

Therefore, it is not necessary to use a separate tool or member such as staples in order to prevent the mount 4 from falling off, and the workability at the time of fixing the mount 4 is improved, and at the same time, the effect of preventing the mount 4 can be easily obtained. Further, the opening operation can be easily performed.
The distance d1 between the lower tip of the folded flat plate-like portion of the sliding flap 5 and the lower edge of the blister cover 3 is related to the paper gap 6 after turning the lower edge of the back mount 4b. The length is set such that the stopper flap 8 can be easily inserted and pulled out. This distance d1 is 10 to 14 mm, preferably about 12 mm, regardless of the vertical length of the blister cover 3 corresponding to the object to be accommodated.

Next, 2nd Embodiment of this invention is described based on drawing.
The blister pack 1 of the second embodiment is most different from the first embodiment described above in that the mount 4 is folded to form the first paper gap 6a formed at the upper end of the mount 4 and the lower end of the mount 4. The second paper gap 6b is provided, the upper and lower edges of the blister cover 3 are respectively provided with locking flaps 8, and each of the locking flaps 8 is the first paper gap 6a. And it is in the point which prevents the base_sheet | mounting_paper 4 from falling out from the blister cover 3 by inserting in the 2nd paper clearance gap 6b, respectively.

As shown in FIG. 5, the blister pack 1 does not have the stop flap 7, and the blister cover 3 has an upper end edge and a lower end edge that can be freely folded back to the back side through a crease 10. Each flap 8 is provided.
The mount 4 is a long and narrow rectangle, and is formed between the front mount 4a and the center mount 4c at the lower end of the mount 4 by being configured as a trifold continuous at the upper edge and the lower edge. A first paper gap 6 a is provided, and a second paper gap 6 b is formed between the central mount 4 c and the back mount 4 b at the upper end of the mount 4.

Then, the usage aspect of 2nd Embodiment of this invention is demonstrated.
When the product is stored in the blister pack 1, the product is put in the recess 2 of the blister cover 3, and the left and right side edges of the mount 4 are fitted to the left and right slide flaps 5 from the lower end or the upper end of the blister cover 3. Then, the upper edge or the lower edge of the mount 4 is aligned with the fold line 10 of each locking flap 8.
First, both lower ends of the back side mount 4b and the center mount 4c are turned upward, and the upper end of the back side mount 4b is turned downward. Next, each locking flap 8 is folded back and the free ends of each locking flap 8 are inserted into the first paper gap 6a and the second paper gap 6b, respectively. Thereafter, both lower ends of the back side mount 4b and the center mount 4c and the upper end of the back side mount 4b are restored. In this way, both the paper gaps 6a and 6b of the mount 4 and the respective locking flaps 8 are locked.

Therefore, when the mount 4 tries to move upward or downward after setting the mount 4, the movement of the mount 4 is restricted by the locking flaps 8. Therefore, the mount 4 is securely engaged with the blister cover 3 to prevent the mount 4 from coming off, which is effective for preventing the product from falling off.
When removing the mount 4 from the blister pack 1, both lower ends of the back mount 4 b and the center mount 4 c are turned upward, and the upper ends of the back mount 4 b are turned downward. It is only necessary to pull out the free end from both the paper gaps 6a and 6b.
Therefore, in the second embodiment, it is possible to improve the workability when fixing the mount 4 while omitting the step of forming the stop flap 7 that requires folding, and at the same time, it is possible to easily obtain the effect of retaining. .

The distance d1 and the distance d2 between the upper end of the folded flat plate portion of the slide flap 5 and the upper edge of the blister cover 3 are both the back side mount 4b and the center mount 4c. After turning the lower end and the upper end of the back mount 4b, the length is set so that the locking flap 8 can be easily inserted into and pulled out from the paper gaps 6a and 6b. Both the distances d1 and d2 are 10 to 14 mm, preferably about 12 mm, regardless of the vertical length of the blister cover 3 corresponding to the object to be accommodated.
The mount 4 is configured as a two-fold elongated rectangular shape that is continuous on either the left end edge or the right end edge, so that the front side mount 4a and the back side mount are provided at the upper and lower ends of the mount 4 respectively. You may have the 1st paper clearance 6a and the 2nd paper clearance 6b formed between 4b. At this time, the left edge or the right edge of the mount 4 may be cut at a distance d1 from the lower end edge of the mount 4 and may be cut at a distance d2 from the upper edge of the mount 4. Further, the mount 4 is folded three or more times so as to be continuous at any one of the upper, lower, left and right edges, whereby a first paper gap 6 a formed at the upper end of the mount 4 and a first formed at the lower end of the mount 4. An elongated rectangular shape having two paper gaps 6b may be used.
