Description

  The present invention relates to a battery package that can be suspended in a state in which a hook portion is provided and a cylindrical battery is accommodated. Specifically, the present invention relates to a paper battery package that is assembled by bending a single mount along a folding line.

  It is often seen that a cylindrical battery (hereinafter referred to as a battery) whose size is designated by a designation such as “single” or “AA” is sold in stores in a state where it is housed in a suspendable package. In recent years, paper battery packages made entirely of paper have been increasingly used from the viewpoint of environmental considerations and separate collection when garbage is collected. FIG. 8 shows an example of a conventional paper battery package. FIGS. 1A and 1B are a perspective view from the front and a perspective view from the rear, respectively. The battery package 1e has a basic shape in which a hook part 110 with a hole 111 for suspension is formed above the box part 100 serving as a battery storage space. The box part 100 confirms the contents. Left and right connected to each of the left and right edges (121L, 121R) of the front surface 101, with the front surface 101 and the rear surface 102 having an open rectangular window 120 as a main body. The side surfaces (105L, 105R) of the square tube are closed at both ends.

  In this structure, the hook part 110 is attached in a state where two front and rear surfaces are laminated, the rear face 102 is wider than the front face 101 of the box part 100, and the rear face 102 extends upward to hook part 110. It is integrated with the rear side. Further, the front surface 101 of the box part 100 has a left-right width (w100) corresponding to the battery to be stored, and the left and right edges (121L, 121R) of the front surface 101 are continuous with the left and right side surfaces (105L, 105R), The side surfaces (105L, 105R) are connected to the laminated surface (106L, 106R) with the rear surface 102 via fold lines (122L, 122R) parallel to the left and right edges (121L, 121R). Therefore, in the battery package 1e in the above-described conventional example, the left and right lengths w100 of the box part 100 differ depending on the size of the battery to be stored.

  By the way, the battery package 1e is assembled starting from the mount 200c on which the folding line shown in FIG. 9 is defined. In this figure, the alternate long and short dash line is a trough (121R, 121L, 123-125) fold line (from the back of the page), and the chain line is a mountain fold line (122L, 122R, 123, 126). Are bent so that adjacent surfaces are orthogonal to each other.

FIGS. 10A to 10C show an assembling procedure until the mount 200c is changed to the battery package 1e shown in FIG. Usually, a battery manufacturer causes a specialized manufacturer to manufacture a mount. The specialized manufacturer then folds the mount 200c vertically and folds the surfaces (rear hook portion 113, front hook portion 112) disposed on the upper and lower ends of the mount 200c and adheres them to each other. (A). From this state, first, the folding line (123 to 126) extending in the left-right direction is bent in the mount 200c, and the upper surface 103 and the lower surface 104 are raised. As a result, the front surface 101 and the rear surface 102 are connected to each other by the upper and lower surfaces (103, 104) (B). Next, one of the flaps (130L, 130R) extending right and left like a wing shape with the left and right edges (121L, 121R) of the front surface 101 as the base end is valley-folded at the base end (121L, 121R) and the base end ( 121L, 121R) is folded along a fold line (122L, 122R) on the front end side parallel to it. Accordingly, the base end (121L, 121R) side surface (105L, 105R) of the flap (130L, 130R) becomes the side surface (105L, 105R) of the box portion 100, and the front end side surface (106L, 106R) is the box portion. It is laminated on the left and right sides of the rear surface 102 of the 100. Then, the back side of the front surface (106L, 106R) and the front surface of the rear surface 102 are bonded to each other by heat sealing using an adhesive (C). The other flaps (130R, 130L) are similarly bent and bonded to complete the battery package 1e shown in FIG. The battery is stored, for example, when the square tube of the box portion 100 is raised (B) or when the front surface (106L, 106R) of one side flap (130L, 130R) is bonded to the rear surface 102 (C ) Etc. may be performed in a timely manner. The following Patent Documents 1 to 3 describe a paper battery package having a structure different from that of the conventional example.
JP-A-8-230934 JP 2003-86161 A Japanese Patent No. 3784329

  In the battery package shown as a conventional example, equipment such as a heat sealing device for sealing the box part is required in the assembly process from the mount with the hook parts on the front and rear surfaces attached to the battery package. It becomes. For this reason, for example, if the production base is shifted overseas where labor costs are low and the battery package is assembled there to reduce costs, the initial capital investment for starting up the production base will increase. There is a possibility that the cost reduction effect as intended cannot be obtained.

  Although the battery package described in Patent Document 3 has a structure that does not require heat sealing in the assembly process, the battery package is displayed at the store in addition to demands for cost reduction such as ease of assembly. Sometimes “look” is also required. The battery packages described in the above conventional examples and the above patent documents differ in the left and right sizes of the box part depending on the size of the battery to be stored. Damaged. Even if the price is low, if it doesn't look good at the store, it shouldn't be motivated to buy it unless it is a consumer who is really in need. Of course, the battery package is required to have a basic function of reliably protecting the battery stored during transportation before appearance of cost and appearance.

  Therefore, the present invention is made of environmentally friendly paper, can be assembled at a low cost without requiring a manufacturing process using a machine such as a heat sealing process, and has an excellent aesthetic when displayed at a storefront, and An object of the present invention is to provide a paper battery package capable of reliably protecting a battery stored during transportation.

The inner flap is folded at the base end and folded inside the box, and is bent inside the box so as to be substantially U-shaped by two mountain fold lines parallel to the base end. As a result, the inside of the box is partitioned into three spaces, left, right, and center, and the center space is formed to match the left-right width of the cylindrical battery as a battery storage space,
In the state where the inner flap portion is bent in a substantially U-shape, the outer flap portion is valley-folded to the rear surface side at the base end to form the left and right side surfaces of the box portion, The tip edge is bent by a valley fold line parallel to the base end so as to wrap around the rear surface of the outer flap portion,
A paper battery package in which the box portion is sealed by holding the front edge of the outer flap portion on the rear surface.

  In the paper battery package, it is more preferable that the front edge of the outer flap portion is held by being inserted into a cut defined on the rear surface.

Further, the hook portion is held in a state where a rear hook portion integrally formed above the rear surface and a front hook portion integrally formed on the upper surface via a mountain fold line are stacked. Being
The front hook part includes a hook flap part extending in a wing shape from the left and right edges to the tip edge in the left and right directions,
The hook flap portion is bent at the base end and bent so as to be mixed around the back surface of the rear hook portion, and the tip edge is inserted into the notch defined on the back surface. A paper battery package in which the front hook portion and the rear hook portion are stacked may be used.

  According to the paper battery package of the present invention, it is possible to achieve cost reduction while dealing with environmental problems, and it is possible to promote consumers' willingness to purchase with an excellent aesthetic appearance. Further, the stored battery can be reliably protected.

=== Basic structure of battery package ===
FIG. 1 shows the appearance of a paper battery package (hereinafter referred to as a battery package) 1a according to an embodiment of the present invention. 2A shows a partially broken perspective view of the battery package 1a in a state where the battery is stored in the box 90, and FIG. 2B shows a cross-sectional view taken along the line aa in FIG. Indicated. The battery package 1a according to the present embodiment has a basic shape in which a hook portion 10 having the same width as the box portion 90 is formed above a substantially rectangular parallelepiped box portion 90. The box portion 90 includes the rear surface 2 and the contents. The left and right side surfaces (5L) are formed on the left and right edges (21L, 21R) of the front surface 3 with a substantially rectangular tube connected to the upper surface 3 and the lower surface 4 as a main body. , 5R) and the surfaces (6L, 6R) that wrap around the rear surface are connected to the rear side edges (22L, 22R) of the side surfaces (5L, 5R). And the box part 90 is sealed because the front-end | tip of the surface (6L, 6R) which goes around to this rear surface is hold | maintained by the rear surface 2. FIG. The tip may be held by an adhesive tape or the like, but in this example, the tip is held by being inserted into a wave-like cut 50 defined on the rear surface 2. Thereby, an extremely environmentally friendly battery package which does not use any material other than paper can be obtained. Further, the battery package can be opened and sealed by inserting and removing the tip from the insertion 50. For example, the battery package 1a can be reused as a carrying case for a spare rechargeable battery.

  Further, inside the box part 90, flaps (inner flaps: 40L, 40R) connected to the left and right edges (44L, 44R) of the rear surface 2 are housed in a state of being bent into a substantially U-shape. The inner flaps (40L, 40R) are connected to three surfaces (41L to 43L, 41R to 43R) from the left and right edges (44L, 44R) of the rear surface 2 toward the front end. The surface forms a lower side (41L, 41R), a side side (42L, 42R), and a lower side (43L, 43R) in a substantially U-shaped cross section. The inside of the box 90 is divided into three spaces (90L, 90R, 90C) on the left, right, and center by the inner flaps (40L, 40R) bent into the substantially U-shape and stored in the box 90. Partitioned.

  Of these three spaces (90L, 90R, 90C), the central space 90C is a space in which the batteries 80 are accommodated. In this example, a plurality of cylindrical batteries 80 are accommodated in a line vertically. Has been. Of course, they may be arranged in a line on the left and right. The width of the storage battery 80, that is, the left and right lengths of each battery 80 (the left and right widths of the rows when arranged in the left and right rows) is the left and right width of the central space 90 </ b> C in the box portion 90. The cylindrical end faces of the batteries 80 substantially coincide with each other and come into contact with the side surfaces (42L, 42R) of the inner flaps (40L, 40R) bent in a substantially U-shape so that the battery 80 moves in the box 90. In addition to limiting, the left and right spaces (90L, 90R) formed by the inner flaps (40L, 40R) interfere with external impacts and reliably protect the battery 80 in the box 90.

  Furthermore, the battery package 1a in the present embodiment can make the left and right widths of the box portion 90 coincide with the full width w of the battery package 1a regardless of the size of the battery 80 to be accommodated, and the width w can be kept constant. can do. As a result, when the battery is displayed at the store, the width w is unified and the appearance can be improved regardless of the size of the battery. The good appearance can be expected to stimulate consumers' willingness to purchase and increase the opportunity to purchase batteries.

=== Mount shape and assembly procedure ===
<Mount>
The battery package 1a of the present embodiment described above is assembled from a single mount on which a fold line is defined. FIG. 3 shows a planar shape of the mount 200a. In this figure, the front side is disposed on the inner surface side of the box portion 90, and the upper and lower sides are disposed on the rear surface side and the front surface side (rear surface hook portion 13 and front surface hook portion 12), respectively. . Moreover, in the figure, valley fold (paper surface, back to front side) lines (21L, 21R, 22L, 22R, 23-25, 44L, 44R) are shown by alternate long and short dash lines, and mountain fold lines (26, 45L, 45R, 46L, 46R) are indicated by chain lines. Hereinafter, the mountain fold / valley fold is defined based on the bending direction at each fold line in the mount 200a of this figure. In addition, the completed battery package 1a is defined as up, down, left, and right with reference to a state when the hook unit 100 is viewed upward and the front surface 2 is viewed from the front.

<Assembly procedure>
FIG. 4 shows an assembling procedure of the battery package 1a. As in the conventional example described above, the assembly is started from a state (A) in which the front hook portion 12 and the rear hook portion 13 to be the hook portion 10 are adhered. First, the upper surface 3 and the lower surface 4 are raised by bending a valley fold line (23 to 26) extending in the left-right direction. Thereby, a substantially rectangular tube formed by the front surface 1 and the rear surface 2, which are the basic structure of the box 90, and the upper surface and the lower surface connecting them is formed, and the outer flap (30L, 30R) and the inner flap (40L, 40R) extends to the left and right while facing each other (B).

  Next, either the left or right inner flap (40L, 40R) is valley-folded at the connecting edge (44L, 44R) with the rear surface 2 and folded back into the box part 90 (C). At the same time, two mountain fold lines (45L, 45R and 46L, 45R) parallel to the fold line (44L, 44R) are bent at a right angle. As a result, the inner flaps (40L, 40R) are housed in the box 90 so as to be substantially U-shaped (D). Similarly, the other inner flaps (40R, 40L) are bent and stored in the box portion 90 so as to be substantially U-shaped. In addition, what is necessary is just to accommodate a battery in the box part 90 at the time of (B) or (D).

  When the battery and the left and right inner flaps (40L, 40R) are stored in the box 90, the left and right outer flaps (30L, 30R) are bent to form the side surfaces (5L, 5R) of the box 90, The part 90 is sealed to complete the battery package 1a. For this purpose, first, the outer flaps (30L, 30R) are folded at the connecting edges (21L, 21R) with the front surface 2 to form the left and right side surfaces (5L, 5R), and the outer flaps (30L, 30R) are formed. The valley fold lines (22L, 22R) parallel to the connecting edges (21L, 21R) are bent (E) so that the tip side wraps around the rear surface 2. And the front-end | tip part (7L, 7R) of an outer side flap (30L, 30R) is inserted in the notch 50 defined by the rear surface 2, and a sealing state is maintained (F).

  In this embodiment, the tip portions (7L, 7R) of the outer flaps (30L, 30R) form convex tongue pieces (7L, 7R), and the tongue pieces (7L, 7R) are arranged on the rear surface. 2 is inserted into the corrugated cut 50 defined in FIG. The tongue pieces (7L, 7R) are chamfered at the corners 332 of the leading edge in order to facilitate insertion into the cut 50. Further, both ends 33 of the base portion of the tongue piece (7L, 7R) are notched, and after the tongue piece (7L, 7R) is inserted into the notch 50, the notch portion 33 is formed at both ends 51 of the corrugated notch 50. The tongue pieces (7L, 7R) are not easily pulled out.

  As described above, the battery package 1a according to the present embodiment is environmentally friendly because it is assembled from a single paper mount 200a. In addition, the manufacturing process using a special device such as a sealing process is not required, and it is possible to reduce the cost because it can be assembled simply by bending the mount 200a along the fold line. It can respond quickly to relocation of production bases. In addition, the total length w40 of the inner flaps (40L, 40R) and the distance w41 between the base ends (44L, 44R) and the fold lines (45L, 45R) adjacent thereto are appropriately set according to the size of the battery that houses them. Regardless of the size of the battery to be stored, the left and right widths of the box 90 can be unified as the full width w of the battery package. Therefore, it looks good when hung from a store and displayed, and it can be expected to stimulate consumers' willingness to purchase.

=== About the size of the battery package ===
In the battery package 1a of the above embodiment, the length (w40 to w43) of each part of the inner flaps (40L, 40R) is set according to the size of the battery to be stored, so that the full width w of the battery package 1a is a box part. It can be made constant regardless of the left and right widths of the batteries housed in 90. For example, if four LR6 (AA) alkaline batteries are stored side by side and the total width w of the package is defined as 85 mm, the length (≈50 mm) and diameter of one battery (≈14 mm), the height h90 and the depth t of the box part are 52 mm and 14 mm, respectively, and the length of each part in the inner flap (40L, 40R) is w40 = 48, w41 = 17 mm, respectively. What is necessary is just to set it as w42 = 14mm and w43 = 17mm. In addition, since the surface (41L, 41R) on the base end (44L, 44R) side of the inner flap (40L, 40R) is folded back into the box portion 90, the width (folded width) w41 is the left and right of the battery to be stored. It is necessary to adjust to the correct length according to the width, but the inner side flaps (40L, 40R) are bent in a U-shape on the front side surfaces (43L, 43R) of the inner side flaps (40L, 40R). Therefore, the length w42 only needs to satisfy w41 ≧ w42> 0.

  Furthermore, by setting the height h10 of the hook part according to the height h90 of the box part 90, the overall height h of the battery package can be made constant regardless of the battery size. Here, the size (w40, w41, h1) of each part of the battery package 1a when the total width w and the total height h of the battery package 1a are constant (w = 85 mm, h = 108 mm), the size and number of the storage batteries, The relationship is illustrated. It is assumed that the batteries are stored in the box portion 90 in a line in the vertical direction.

Table 1 below shows the size and number of storage batteries and the size of each part.

=== About the structure of the hook portion ===
In the said Example, the hook part 10 was formed by sticking the front hook part 12 and the rear hook part 13 in the mount 200a. Not limited to this example, for example, a flap (hook flap) extending to the left and right is connected to the front hook portion 12 like the outer flaps (30L, 30R), and the tip of the hook flap is defined on the rear hook surface. It may be inserted into the formed cut and the front and rear hook surfaces may be held in a laminated state. An example of a battery package in which the hook portion is formed using the flap is shown in FIGS. FIG. 5 is an external view of the battery package 1b, and FIG. 6 is a plan view of the mount 200b. Hook flaps (60L, 60R) extending left and right are connected to the left and right edges (27L, 27R) of the front hook portion 12b, and the front ends of the flaps (60L, 60R) are connected to the outer flaps (30L, 30R). Similar tongue pieces (62L, 62R) are formed. The rear hook portion 13b has a corrugated cut 70 similar to that of the rear surface 2 of the box portion 90.

  As a procedure for assembling the battery package 1b, first, the mount 200b is valley-folded along the folding line 24 that divides the upper and lower parts into two, and the front hook part 12b and the rear hook part 13b are laminated. In this state, the hook flaps (60L, 60R) are folded at the connecting edge (27L, 27R) with the front hook portion 13b so that the front end side of the hook flap (60L, 60R) wraps around the back surface of the rear hook portion 13b. And a tongue piece (60L, 60R) is inserted in the notch 70 of the rear surface hook part 13b. In addition, the tongue pieces (62L, 62R) of the hook flaps (60L, 60R) are also tipped to facilitate the insertion into the notches 70, like the tongue pieces (7L, 7R) of the outer flaps (30L, 30R). The corner 63 of the edge is chamfered, and a notch 64 that is caught by the end 71 of the notch 70 is defined at both ends of the base in order to prevent removal after insertion.

  After the hook portion 10b is formed as described above, the battery package 1b may be assembled according to the procedure shown in FIGS. In this way, by holding the front hook portion 12b and the rear hook portion 13b in a laminated state by the hook flaps (60L, 60R), the process for bonding the hook portion 10b becomes unnecessary, and all are assembled manually. Is possible. Moreover, expensive equipment such as a heat sealing device is not required, and the cost can be further reduced.

=== Modification Example of Hook Part ===
The shape and structure of the hook portion are not limited to the above embodiment, and may be any shape as long as the battery is suspended in the box portion. FIGS. 7A and 7B illustrate battery packages having different hook shapes and structures. (A) illustrates a battery package in which the shape of the hook portion is different from that of the above embodiments (1a, 1b). In the battery package 1c, the hook portion 10c has a bowl shape. Moreover, the battery package from which the structure of the hook part differs in (B) was illustrated. In this battery package 1d, the hook portion 10c is not made to have a structure in which the front and rear flap portions (12, 13, or 12b, 13b) are stacked as in the above embodiment (1a, 1b), and only the rear hook portion 13d. It has a structure to hang. In this example, the insert 14 is connected to the upper surface 3 in place of the front hook portions (12, 12b). The insertion portion 14 is inserted between the proximal surface (41L, 41R) and the rear surface 2 of the inner flaps (40L, 40R) in the box portion 90 so that the box portion 90 is connected to the upper surface 3. It is sealed by the side surfaces (5L, 5R).
