BACKGROUND OF THE INVENTION
The present invention relates to a battery blister case, and more particularly to a battery blister case that is effective for use in packaging a plurality of cylindrical batteries in a state suitable for store display.
[0002]
[Prior art]
For example, a cylindrical battery such as an AA type battery is usually displayed and packaged in advance by a plurality of pieces, and is used in the distribution market. A so-called blister case is often used as the packaging means. The battery blister case is formed by integrally forming a battery storage portion on a thermoplastic transparent resin thin plate such as a PET resin by vacuum mold forming processing. For example, as shown in FIG. 5 or FIG. Then, a hanging type display package is formed by pasting on the mount 30.
[0003]
Conventionally, as this type of battery blister case 10, as shown in FIG. 5, a type in which a plurality of batteries 40 are arranged and stored together in a single tray-like container portion 121, and as shown in FIG. There is a type in which the batteries 40 are individually stored in the container portion 122 one by one.
[0004]
The former collective storage type has the following advantages.
(1) Since a plurality of batteries can be stored densely and collectively, space utilization efficiency is high, and the case size can be reduced to save store display space.
(2) Since the shape is relatively simple, it is easy to remove the mold at the time of mold forming, and the productivity is good.
(3) Since it is stored in a batch, the work efficiency when storing the battery in the case is good.
(4) Since the case size can be reduced, the molding material cost can be reduced, and the number of products obtained per material and process can be increased. Even when a mount is pasted to create a package, the number of materials and the number of products obtained per process can be increased. In addition, the amount of waste generated when it is used can be reduced.
[0005]
On the other hand, the latter individual storage type has the following advantages.
(1) Since the batteries are individually stored one by one, each battery can be securely held. Thereby, it is possible to prevent the battery from falling and falling when the mount is peeled off and the package is opened. In addition, the battery can be prevented from popping out due to an impact caused by transportation or accidental dropping.
(2) By individually storing the batteries one by one, the batteries can be securely held so that they do not rotate freely during handling such as transportation. Thereby, the label surface of a battery can always be aligned in the same direction, and the appeal effect of goods display can be heightened.
[0006]
[Problems to be solved by the invention]
The collective storage type shown in FIG. 5 has the following problems.
(1) When a plurality of batteries are collectively stored, the batteries are scattered and easily fall off when the package is opened. In addition, it is easy for a battery to pop out due to an impact caused by transportation or accidental dropping.
(2) It is impossible to prevent the batteries in the package from rotating freely during handling such as transportation. If the battery rotates freely, the label direction of the battery becomes uneven and the appeal effect of the product display is impaired.
[0007]
On the other hand, the individual storage type shown in FIG. 6 has the following problems.
(1) Since a plurality of container parts are formed, the space utilization efficiency is poor and the case size is increased. Accordingly, a large product display space is required.
(2) In order to hold the battery securely, it is necessary to form a hollow container part that surrounds and wraps around the battery-side body part for more than a half circumference. Reduce.
(3) Since the batteries are individually stored, the packaging work efficiency is poor.
(4) As the case size increases, the molding material cost increases and the number of products obtained per material and process decreases. Even when a mount is pasted to create a package, the number of materials and the number of products taken per process are reduced. In addition, the amount of waste generated when used is increased.
[0008]
The present invention has been made in view of the above problems, and solves the problems of the conventional collective storage type and the individual storage type, respectively, and combines only the advantages of both types without contradiction. Provide a blister case made possible. In other words, a blister for a battery that has a structure suitable for improving productivity, reducing costs, saving product display space, etc., and can hold a plurality of batteries while securely holding them so that they do not rotate freely. Provide a case.
[0009]
[Means for Solving the Problems]
The means according to the present invention is a battery blister case in which a predetermined battery housing structure is formed by molding a thermoplastic transparent resin thin plate .
(1) A tray-like container portion is formed for storing a plurality of cylindrical batteries in a row and densely arranged in a lateral direction .
(2) The bottom of the container part is formed with an arc-shaped groove array that fits while the bottom surface of the battery array that is stored together fits .
(3) On the side surface of the container portion where the positive electrode terminals of the batteries that are collectively stored with the terminal direction aligned are formed, a storage recess for fitting the protrusion of the positive electrode terminal is formed ,
(4) The convex part which latches and holds the negative electrode terminal side cylinder end of the battery from the opening end side of the container part is formed .

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an embodiment of a blister case according to the present invention. The blister case 10 shown in the figure is a vacuum transparent die molding process of a thermoplastic transparent resin thin plate such as a pet resin. The battery 40 is housed and affixed to the mount 30 to suspend the display package. Form. The blister case 10 is formed with a single tray-like container portion 12 that collectively stores a plurality of cylindrical batteries 40 in a row in the horizontal direction. On the bottom surface of the tray-like container portion 12, there is formed an arcuate groove array 14 into which the lower surface of the battery array stored together is fitted while conforming to the shape.
[0012]
The battery 40 is accommodated in the tray-like container portion 12 with the protruding positive electrode terminal 44 and the flat negative electrode terminal 46 aligned on the same side, but as shown in FIG. On the side surface (side wall surface) of the container, a housing recess 16 into which the projection of the positive electrode terminal 44 is fitted is formed. Further, on the container side surface (side wall surface) on the negative electrode terminal 46 side, a convex portion 18 is formed that holds and holds the outer cylinder end on the negative electrode terminal 46 side from the opening end side of the tray-like container portion 10. . The protrusions 18 are formed so as to be interposed between the batteries 40 accommodated in a horizontal row.
[0013]
The blister case 10 described above forms an open tray-like container portion 12 that hardly wraps upwards as a whole, and therefore has excellent die-cutting performance during mold forming and excellent productivity. Since the batteries 40 are stored together in a closely arranged state, the space utilization efficiency is high, and the case size can be reduced to save the store display space. Since a plurality of batteries can be stored together, the workability of packaging for storing the battery 40 in the case 10 is good. Since the case size can be reduced, the molding material cost can be reduced, and the number of products obtained per material and process can be increased. Even when the mount 30 is pasted to create a package, it is possible to increase the number of products obtained per material and process. Further, it is possible to reduce the amount of waste generated when used.

However, it is possible to prevent the battery from falling off when the package is opened. Similarly, it is possible to prevent the battery from popping out due to an impact caused by transportation or accidental dropping. The effect of locking and holding the battery by the concave portion 16 and the convex portion 18 is accompanied by an appropriate frictional resistance acting between the battery and the case and a spring effect due to the flexibility of the case. It does not impede storage and removal.
[0015]
Further, each battery 40 in the tray-like container part 10 is fitted in the arcuate groove array 14 on the bottom surface of the container part 10 in a shape-fit state, and both ends are locked by the concave part 16 and the convex part 18. -By being held, it is securely held so that it does not rotate freely during handling such as transportation. Thereby, the display label 42 surface of a battery can always be kept aligned in a fixed direction, and the appeal effect of goods display can be heightened.
[0016]
FIG. 3 shows an embodiment of the storage recess 16 that holds and holds the end of the battery 40 on the positive electrode terminal 44 side. The recess 16 is preferably an independent shape as shown in FIG. 5A, but may be a continuous shape as shown in FIG. Further, as shown in (c), the concave portions 16 are formed into independent shapes, the guide grooves 20 for introducing the positive electrode terminals 44 into the respective concave portions 16 are formed, and intermediate portions of the guide grooves 20 are formed at the intermediate portions of the positive electrode terminals 44. If formed to be narrower than the protrusion, the battery 40 can be smoothly stored and taken out without impairing the holding effect of the battery 40.
[0017]
FIG. 4 shows an embodiment of the protrusion 18 that holds and holds the battery 40 on the negative electrode terminal 46 side.
In the same figure, (a) shows an example in which the convex portion 18 is formed so as to lock the outer cylinder end of the battery 40. Further, (b) and (c) show examples in which the convex portion and the annular convex portion 18 are formed so as to latch the stepped portion 48 between the outer tube of the battery 40 and the negative electrode terminal. In either case, the cylindrical end on the negative electrode terminal side 46 of the battery 40 can be locked and held.
