Description

  The present invention relates to a dry cell container in which a plurality of dry cells are accommodated.

  In general, this type of dry battery is sold in a blister pack, for example, in a set of four batteries. As is well known, this blister pack is composed of a case body made of a plastic sheet having a receiving recess formed on the back surface formed by sheet molding, and a mount bonded to the back surface of the case body so as to close the receiving recess. It is. And a dry cell can be taken out from an accommodation recessed part by peeling a base_sheet | mounting_paper from a case main body.

  However, the blister pack mainly has the following problems. First, since the housing recess is formed by sheet molding, there are restrictions on printing on the plastic sheet. In addition, it is necessary to peel off the backing sheet when opening, but it is difficult to completely peel off and completely open the receiving recess, and part of the backing remains without being peeled or the receiving recess is partially opened. As a result, it is not always easy to take out a dry battery as an object to be contained. In particular, recently, a dry battery package in which a plurality of dry batteries are packaged together with a shrink film in a parallel state may be accommodated as an object to be accommodated. It cannot be taken out. Furthermore, in the case of a blister pack, the manufacturing cost is likely to increase due to the need for a mold in sheet molding and the need for two members, a plastic sheet and a mount.

  Then, this invention is made | formed in view of the said conventional problem, and makes it a subject to provide the dry battery container which can be printed easily, can take out the accommodated dry battery package easily, and can be manufactured cheaply. .

The present invention has been made to solve the above-described problems, and a dry battery container according to the present invention is a package of a plurality of dry batteries in a parallel state in a dry battery container of a case made of a plastic sheet. A dry cell container in which a dry cell package is accommodated, wherein the dry cell container is formed by bending one end of the belt-shaped plastic sheet in the longitudinal direction to the other end and fixing the sheet to the sheet. It is formed in a sleeve shape that is open on both sides in the short direction, and cuts are provided in the vicinity of both openings of the dry cell housing part, and the outside of the cuts is used to prevent the dry cell package from coming off from the dry cell container. A stopper latching piece is formed, and the stopper latching piece is deformed toward the inside of the dry cell housing portion to latch the dry battery packaging body at the inner edge thereof.
In addition, the notch includes not only a linear shape but also a slit shape having a predetermined width.

  In the dry battery container having such a structure, the dry battery package is accommodated in a sleeve-like dry battery container formed from a strip-shaped plastic sheet, so that sheet molding is not required, and therefore, the plastic sheet is easy to use. Can be printed. The sleeve-shaped dry cell housing is open on both sides, but the retaining latch that is deformed inward of the dry cell housing locks the dry cell pack at the inner edge of the sheet end face. Therefore, the dry battery package is prevented from coming out from the opening of the dry battery housing part. On the other hand, since the dry cell housing part is in a sleeve shape, the dry battery package can be easily taken out from both sides of the dry battery housing part by releasing the locking state by the retaining locking piece. Furthermore, since the sleeve-like dry cell housing portion is formed from a plastic sheet, a mount such as a blister pack is unnecessary, and the retaining latch piece is also formed by cutting, so that the dry cell packaging body A separate member is not required for preventing the slipping, and therefore it can be manufactured at low cost.

  In particular, it is preferable that a part of the retaining latch piece is fixed to the inner surface of the dry battery housing portion facing the retaining latch piece. Since it is not released, and it is necessary to separate the fixed retaining locking piece, even if the locking state of the retaining locking piece is released by mischief, traces of mischief will remain on the case. Remains and the tamper function is exhibited.

  As described above, in the dry cell container according to the present invention, the sleeve-like dry cell container is formed by the belt-shaped plastic sheet, and a part of the sleeve is used as a retaining latch to latch the dry cell package. Therefore, it is easy to perform printing, and the contained dry battery package can be easily taken out, and can be manufactured at low cost.

Hereinafter, an embodiment of a dry cell container according to the present invention will be described with reference to the drawings.
The figure which looked at the dry cell container in this embodiment from the back surface is shown in FIG. 1, and the figure which looked at the dry cell container from the side is shown in FIG.
The dry cell container includes a dry cell package 1 in which a plurality of dry cells B are packaged together with a shrink film in a parallel state (shrink wrap), and a dry cell container 3 for accommodating the dry cell package 1. It consists of.

  The dry battery package 1 is a package in which a plurality of dry batteries B, for example, AA or AAA are packaged together. Various known shrink films are used. In particular, a transparent film is preferable because the pattern on the surface of the dry battery B can be seen from the outside.

  The case 2 is composed of a transparent plastic sheet 20. The plastic sheet 20 is formed from a synthetic resin such as polyester such as polyethylene terephthalate, polyvinyl chloride, polypropylene, polystyrene, or the like, and has a thickness of 0.1 mm to 0.8 mm. used. As shown in FIG. 3, the plastic sheet 20 has a strip shape with a substantially constant width. On the plastic sheet 20, bent ruled lines 21 are formed at intervals along the width direction (short direction), and the plastic sheet 20 is partitioned into five parts by these bent ruled lines 21. And the case 2 which has the sleeve-shaped dry cell accommodating part 3 is formed by bend | folding the plastic sheet 20 along the bending ruled line 21. FIG. That is, by bending the lower end portion (one end portion) of the plastic sheet 20 toward the upper end portion (the other end portion) and bonding (fixing) the bonding margin portion 22 to the middle portion of the plastic sheet 20, A sleeve-shaped dry cell housing 3 that opens (left and right) is formed below the case 2. The dry cell storage unit 3 has a rectangular tube shape corresponding to the shape of the dry cell package 1 to be stored, and has a vertically long rectangular cross section. That is, the case 2 includes a dry cell housing portion 3 composed of an upper surface wall 31, a lower surface wall 32, a front wall 33, and a back wall 34, and an upward extending piece 4 that extends upward from the back wall 34 of the dry cell housing portion 3. And. The bonding margin 22 is bonded to the back wall 34. As described above, the plastic sheet 20 is divided into five parts by the bent ruled lines 21, and these parts are, in order from the bottom, the bonding margin part 22, the upper surface wall part 23 that becomes the upper surface wall 31, and They are a front wall portion 24 that becomes the front wall 33, a lower surface wall portion 25 that becomes the lower surface wall 32, a back wall 34 and a back surface portion 26 that becomes the upwardly extending piece 4.

Further, leg protrusions 5 are respectively extended from the lower end of the front wall 33 and the lower end of the back wall 34 of the dry cell housing 3. The leg protrusion 5 protrudes downward from the lower wall 32 of the dry cell housing 3, and the case 2 is configured to be able to stand by the plurality of leg protrusions 5. In addition, although the shape, the number, and the like of the leg protrusions 5 are arbitrary, in this embodiment, two points are formed on the front side, and one point is formed on the rear side. As shown in FIG. 3, the leg protrusions 5 are formed on a portion of the plastic sheet 20 that becomes the lower surface wall 32 of the dry cell housing portion 3, that is, on the lower surface wall portion 25, with a substantially square shape starting from the bent ruled line 21. It is formed by providing a letter-shaped protrusion 27 for the projecting piece.
The upwardly extending piece 4 is formed with a suspension hole 6 for suspending the case 2. Accordingly, the case 2 can be displayed in a suspended state by the suspension holes 6 in addition to the standing state by the leg protrusions 5.
Further, the front wall 33 is provided with a strip-shaped cut piece 51 that can be contacted and separated from other parts by a pair of cut lines 50. The pair of cut lines 50 are parallel to each other, are formed in a straight line along the lateral direction, and cross the sheet 20.

  And the dry cell packaging body 1 is accommodated in the dry cell accommodating part 3 so that the axis line may follow the left-right direction of the case 2, ie, the transversal direction of the plastic sheet 20. FIG. Since the dry cell housing part 3 has a horizontal sleeve shape that is open on both the left and right sides as described above, the dry battery housing part 3 has a structure for preventing the dry battery packaging body 1 from being removed from the left and right openings 7. A pair of left and right retaining stoppers 8 are provided. The retaining locking piece 8 is formed by forming a linear cut 28 along the vertical direction (longitudinal direction of the plastic sheet 20) from the back wall 34 to the bottom wall 32 of the dry cell housing 3. That is, the cut 28 is formed so as to straddle the folding ruled line 21 between the back wall 34 and the bottom wall 32. The cut 28 is formed from a substantially central portion of the lower surface wall 32 in the front-rear direction to a vicinity of approximately 1/3 of the upper surface of the back wall 34. By forming the cut 28 in this way, the retaining locking piece 8 is formed between the cut 28 and the side edge portion 20a of the plastic sheet 20 with a substantially constant width, and the back wall 34 and the bottom wall 32 are separated from each other. It is formed so as to straddle the corners between them. A bent ruled line 29 is formed from the lower end of the cut 28 to the side edge 20a of the plastic sheet 20. The bent ruled line 29 is substantially orthogonal to the notch 28 and the side edge 20 a of the plastic sheet 20.

  The retaining latching piece 8 is configured to latch the dry battery pack 1 by an edge 8a (inner edge) on the cut 28 side. Therefore, the retaining locking piece 8 is deformed from the back wall 34 toward the inside of the dry cell housing 3. Specifically, the retaining latching piece 8 is deformed into a state of being curved forwardly convex toward the front wall 33 side. At that time, the bent ruled line 29 is folded into a mountain fold. The retaining locking piece 8 is fixed to the inner surface of the front wall 33 at the top. Examples of the fixing method include ultrasonic sealing, use of an adhesive such as hot melt, welding, and heat sealing. In FIG. 1, the code | symbol 9 is an adhering part. In this way, a part of the retaining latching piece 8 is fixed to the front wall 33, so that the deformed state of the retaining latching piece 8 is maintained.

  The dry cell container in the present embodiment is configured as described above. However, as a method of accommodating the dry cell package 1 in the dry cell container 3 of the case 2, the dry cell container 3 is left or right after the case 2 is formed. In addition to the method of inserting from the opening 7, the plastic sheet 20 is folded while the dry battery package 1 is wound with the plastic sheet 20 to form the dry battery housing part 3, and the dry battery package 1 is housed. There is also a method. And after accommodating the dry cell packaging body 1, the retaining latching piece 8 is bent and deformed in the direction of the normal line by pressing the retaining latching piece 8 from the rear to the front, for example, an ultrasonic seal As a result, the retaining locking piece 8 is fixed to the front wall 33 with a point seal and the deformed state is maintained.

In the dry battery container formed in this way, the case 2 having the dry battery container 3 is formed from a single plastic sheet 20, and therefore, it is easier to manufacture than the conventional blister pack. Can do. And since sheet shaping | molding is unnecessary, various printing can be performed to the plastic sheet 20 easily and accurately. Further, since the belt-shaped plastic sheet 20 is used, the manufacturing cost is low, and the waste of the sheet is less than that in the case of a general box shape. Furthermore, since the left and right retaining pieces 8 are provided as a pair on the left and right sides, it is possible to effectively prevent the dry battery pack 1 from falling off from the left and right openings 7. In particular, since the retaining latching piece 8 is configured to be latched by the edge 8a (sheet end surface) on the cut 28 side, it is strong against the force received from the dry cell packaging body 1 and securely latches the dry cell packaging body 1. can do. Moreover, since it is deformed into a curved state, the length of locking the dry cell package 1 is long and the stability of the accommodated dry cell package 1 is high compared to a configuration deformed into a bent state. There are advantages. Further, in the case of a configuration in which the dry batteries B are individually accommodated, the retaining latching pieces 8 need to latch all the dry batteries B. However, since the dry batteries B are collectively shrink-wrapped, the retaining latches There exists an advantage that the piece 8 can prevent the drop-off | omission reliably by latching a part of dry cell packaging body 1. FIG. Further, since the retaining locking piece 8 is fixed to the inner surface of the front wall 33, the locking state by the retaining locking piece 8 can be easily released by tampering at the store as compared to the case where it is not fixed. Even if it is released, the trace remains, so that it can be easily confirmed and a so-called tamper function is exhibited.
On the other hand, when taking out the accommodated dry battery packaging body 1, the dry cell packaging body 1 can be easily taken out by separating the separating piece 51 from other portions and dividing the front wall 33 into two parts. Moreover, the dry cell packaging body 1 can also be easily taken out by separating the retaining latching piece 8 from the front wall 33 and returning the retaining latching piece 8 to its original state. That is, by returning the retainer locking piece 8 from the curved deformation state to the original state, the dry cell packaging body 1 can be taken out from the opening 7 of the sleeve-shaped dry cell housing 3. Thus, with the simple configuration of the retaining stopper piece 8, it is possible to achieve both prevention of falling off of the dry battery package 1 and good take-out property.

  In the present embodiment, the retaining locking piece 8 is formed on the back wall 34 side, but may be formed on the front wall 33 side. However, it is preferable to form it on the back wall 34 side because the display space on the front wall 33 can be increased.

  Further, the retaining latching piece 8 may be deformed not in a curved state but in a bent state, and in any case, it only has to be deformed toward the inside of the dry cell housing portion 3. For example, as shown in FIGS. 4 and 5, the retaining locking piece 8 may be bent and deformed substantially at a right angle. As shown in FIG. 4, a pair of upper and lower retaining locking pieces 8 may be provided in the left and right openings 7. In that case, the cuts 28 may be provided on both the front wall 33 side and the back wall 34 side so that the direction of deformation differs vertically. Even in the case of bending and deforming in this way, it is preferable to secure the tamper property by fixing the retaining stopper 8 to the inner surface of the opposing portion. As shown in FIG. 5, the retaining latching piece 8 is bent and deformed inward of the dry cell housing 3 by being folded in a mountain fold at the folding ruled line 29.

  Further, the retaining locking piece 8 can be formed on the upper surface wall 31 or the lower surface wall 32. For example, as shown in FIGS. 6 and 7, the retaining locking pieces 8 are formed at the left and right ends of the upper surface wall 31 and the lower surface wall 32, respectively, and the substantially central portion of the retaining locking pieces 8 is formed in a valley fold shape. It is good also as a structure which carries out the bending deformation and latches the dry cell packaging body 1 with the edge 8a inside. In addition, a bent ruled line 30 is also provided at a substantially central portion of the retaining stopper piece 8 so as to be easily bent into a valley fold shape. Since the plurality of dry batteries B are packaged together, even if only the upper and lower ends of the dry battery pack 1 are locked by the retaining locking pieces 8 on the upper surface wall 31 and the lower wall 32, the dry battery pack 1 is surely removed. Can be prevented. When the retaining locking pieces 8 are provided on the upper wall 31 and the lower wall 32, the vertical dimension of the front wall 33 and the rear wall 34, that is, the vertical distance between the upper wall 31 and the lower wall 32, is determined by the dry cell packaging body 1. Slightly smaller than the vertical dimension. Thus, when the dry battery packaging body 1 is accommodated, the upper surface wall 31 and the lower surface wall 32 are pushed by the dry battery packaging body 1 and curved upward and downward, respectively, as shown in FIG. The dry battery packaging body 1 can be reliably locked by the retaining locking piece 8 provided at 32.

  Further, the retaining locking pieces 8 are formed at both the left and right ends of the dry cell housing portion 3, but two notches 28 are formed, and the retaining locking pieces 8 are formed between the two notches 28. May be. That is, the retaining stopper 8 may be formed at a position inside the left and right ends. In any case, any structure may be used as long as the cut-out 28 is formed to form the retaining latch piece 8 on the outer side, and the dry battery pack 1 is latched by the inner edge 8a of the retainer latch piece 8. .

  Further, the configuration of the case 2 can be changed in design as appropriate. For example, as shown in FIGS. 6 and 7, a flap 40 may protrude from the upper end of the upwardly extending piece 4. Due to the presence of the protruding flap 40, the dry battery housing can be easily noticeable. At the time of transport packaging, the flap 40 is folded downward along the folding ruled line 21 and inserted into the flap notch 41. By folding back in this way, the flap 40 does not get in the way during transport packaging.

  Moreover, the design of the shape of the dry cell housing 3 can be changed in various ways. It may have a shape other than a rectangular tube shape.

  Furthermore, in the above-described embodiment, the sleeve-like dry cell housing portion 3 and the upward extending piece 4 are formed by bending the lower end portion of the plastic sheet 20 toward the upper end portion and fixing the plastic sheet 20 to the middle portion of the sheet 20. Although configured as described above, the length of the upper extending piece 4 may be made longer or conversely shortened, and the upper extending piece 4 may be omitted. In any case, any configuration may be used as long as the lower end portion of the plastic sheet 20 is bent toward the upper end portion to form the sleeve-shaped dry cell housing portion 3.

  Moreover, the dry battery packaging body 1 may be a packaging form other than shrink packaging.
