DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a dry battery package of the present invention will be described below with reference to FIGS. 1 to 4 in which a plurality of dry batteries A of the same shape are packaged in a packaging case. .

The packaging case comprises a case body 1 formed from a plastic sheet by sheet molding, and a back cover 2 made of a flexible plastic film adhered to the back surface of the case body 1. . Hereinafter, a specific description will be given.

First, the case body 1 is formed from a single plastic sheet and has a plurality of cylindrical dry batteries A.
(E.g., AA or AAA) is provided with a plurality of accommodation recesses 3 for individually accommodating one by one. The housing recesses 3 are all formed in substantially the same shape, and as shown in FIG.
So that the central axis of the
It is provided in a substantially U-shape in cross-section from the front surface and opens to the back surface side. That is, the dry battery A is accommodated in a state of being sandwiched between the case body 1 and the back cover 2 in the radial direction.
A substantially rectangular opening is formed on the back side of the.

Further, housing recesses 3 are provided side by side at predetermined intervals so that the central axes of the plurality of batteries A to be housed are substantially parallel to each other. It is.

Then, one dry battery A is provided in each accommodation recess 3.
As shown in FIG. 2, the back cover 2 is adhered to the entire flat portion on the back surface of the case body 1, and the openings of all the housing recesses 3 are sealed by the back cover 2. still,
The back cover 2 may be composed of a plurality of plastic films.

The back cover 2 has a perforation (cut line) which is broken by pressing the housing recess 3 as a take-out portion from which the dry battery A can be taken out by pressing the housing recess 3 from the front side. It is formed in a straight line. Specifically, a horizontal perforation 4 provided for each accommodation recess 3 is provided.
(Horizontal cutting line) and two vertical perforations 5, 6 (vertical cutting lines) substantially perpendicular to the horizontal perforation 4.

The horizontal perforations 4 are formed so as to straddle the opening of the accommodation recess 3 in the longitudinal direction, and are provided on the back side of each accommodation recess 3. As shown in FIGS. 2 and 3, the horizontal perforation 4 is formed substantially at the center in the lateral direction of the opening of the housing recess 3, that is, at a position substantially corresponding to the central axis of the dry battery A.

The vertical perforations 5 and 6 are arranged side by side at predetermined intervals, and both straddle the openings of all the accommodation recesses 3 in the lateral direction. And one vertical perforation 5 is
The other longitudinal perforation 6 is provided at a position corresponding to one end of both ends in the longitudinal direction of the housing recess 3, and at a position corresponding to substantially the center in the longitudinal direction of the housing recess 3. Therefore, one vertical perforation 5 corresponds to one end of both ends of the dry battery A, and the other vertical perforation 6 corresponds to substantially the center of the dry battery A in the axial direction.

The plastic sheet has a thickness of about 0.1 mm to 0.8 mm, preferably about 0.2 mm.
A sheet of about 0.4 mm to about 0.4 mm made of polyester, polystyrene, polyvinyl chloride, polypropylene, or the like can be used. That is, by pressing the recessed portion 3 protruded by sheet molding from the front side, which is the projecting side, with, for example, a fingertip, the recessed portion 3 can be compressed and deformed to the back side. Can be set.

Further, as the plastic film, a film having heat resistance and strength such as a biaxially oriented polyester film, a biaxially oriented polyamide film, a biaxially oriented polypropylene film and the like can be used. Furthermore, the plastic film is provided on the surface adhered to the case body 1.
The back surface of the case body 1 and a resin having a heat-fusing property are laminated by lamination or coating, and the laminated resin has little friction particularly with the surface of the dry battery A from the viewpoint of easy removal of the dry battery A. The material is preferred.

The dry battery package of the present embodiment is configured as described above, and the dry battery A can be taken out without separating the back cover 2 from the case body 1. Hereinafter, the removal of the dry battery A will be described.

First, the housing recess 3 is pressed from the front side with a fingertip. At this time, the side where one of the vertical perforations 5 is provided (one end in the axial direction of the dry battery A) is locally taken out as the take-out side. Press. Due to the pressing of the housing recess 3, the housing recess 3 is compressed and deformed, and the back cover 2 is pressed to the back side via the dry battery A, so that the vertical perforations 5 are partially broken. Subsequently, the horizontal perforation 4 is broken from the intersection P between the vertical perforation 5 and the horizontal perforation 4 toward the other end of the dry cell A in the axial direction.
4 is also partially broken, and as shown in FIG. 4, an outlet 7 from which the dry battery A can be taken out is formed in the back cover 2 at one axial end of the dry battery A. Therefore, the dry battery A can be easily taken out by taking it out from the take-out port 7 or the like. Also, since the dry batteries A are individually housed in the housing recesses 3 one by one, and each of the housing recesses 3 is provided with a perforation on the back side, only the required number of the batteries A are taken out one by one according to use. be able to.

Further, as shown in FIG. 3, since the horizontal perforations 4 are substantially coincident with the central axis of the dry battery A, the pressing force acts intensively on the horizontal perforations 4 to reduce the strength of the biaxially stretched film. There is an advantage that even the back cover 2 can be effectively broken with a weak force. In addition, since the vertical perforation 5 is provided at one end of the dry battery A in addition to the horizontal perforation 4, the dry battery A can be pushed from one end by locally pressing one end of the housing recess 3. It can be easily taken out,
Since the vertical perforations 6 are separately provided substantially at the center in the longitudinal direction, it can be more easily taken out.

Also, since the batteries A can be individually taken out one by one, the unused batteries A can be stored as they are together with the packaging case. Therefore,
It is easy to discriminate between used and unused batteries, and it is convenient that unused batteries A can be stored together without being dispersed.

Further, when the packaging case is discarded after all the dry batteries A have been taken out as described above, the back cover 2 is also made of plastic, so that it is not necessary to separate and discard it. Since it is in a state of being adhered to 1, it is easy to dispose.

Note that a vertical perforation may be similarly provided at a position corresponding to the other axial end of the dry battery A. In the case where a vertical perforation is provided only on one of the two end portions, a display portion indicating the take-out side may be provided on the surface of the case body 1 or the like.

Further, perforations can also adopt various forms,
In addition to the linear shape, for example, a saw blade shape or a wave shape can be used. Also, instead of a perforated line, a perforated line may be formed in the shape of a groove in the middle of the thickness, and various cutting lines other than the perforated line may be employed. In any case, if a cutting line is used as the take-out portion, the opening of the housing recess 3 can be completely sealed with the back cover 2, and the back surface of the dry battery A is covered with the back cover 2, so that the dry battery A is not damaged. In addition to this, the opening 7 can be formed by breaking the cutting line, and it is easy to achieve both the protection of the dry battery A and the easy removal.

However, a form other than a cutting line such as a perforation can be adopted as the take-out portion. For example, instead of the horizontal perforation 4 shown in FIG. 2, a take-out window 8 as shown in FIG. It can also be formed for each. The take-out window 8
Is a slit along the longitudinal direction of the opening (axial direction of the dry cell A) and is narrower than the dry cell A, so that the dry cell A is held by the back cover 2 and the dry cell A
Never go outside from inside. Then, when the housing recess 3 is pressed from the front side during use, the dry batteries A can be taken out by breaking the vertical perforations 5 and 6 starting from the take-out window 8. If the take-out window 8 can be expanded by pressing the housing recess 3 such as the ductility of the plastic film of the back cover 2 is high, only the take-out window 8 is provided without providing the vertical perforations 5 and 6. You can also. Further, it is also possible to simply provide a cutout such as a straight line or a U-shape as a take-out portion.

As described above, the take-out portion may have any structure as long as the dry cells A can be taken out one by one by pressing the housing recess 3 from the front side. Is within the scope of the present invention.

Note that the dry battery A also has a cylindrical shape,
For example, the shape is not limited, such as a square shape or a flat thin shape such as a button battery.

[0029]

As described above, according to the present invention, since the case body and the back cover are made of plastic, separation and disposal are not required, and even though the back cover is not easily broken by a plastic film. By providing the take-out portions at the positions on the back surface side of the respective accommodating recesses, the individually accommodated dry batteries can be individually taken out one by one by pressing the accommodating recesses from the front side.
