Description

PACKAGE , PARTICULARLY FOR PACKAGING BATTERIES

Technical Field

[0001] The present invention relates to packages, and further particularly relates to a package for packaging and displaying, for example, dry batteries. Background Art

[0002] Conventionally, consumers purchase a plurality of dry batteries at once. Therefore, mainly, the plurality of batteries, for example, two, four, eight, twelve, and fourteen, are sold by being packaged and visibly displayed together.

FIG. 13 shows an example of a package for displaying and selling a plurality of dry batteries. With the package of FIG. 13, a plurality of dry batteries 33 are packed by attaching the peripheral portion of the transparent resin sheet container 32 of for example polyethylene terephthalate (PET) to the base board 31. the base board 31 is provided with the hanging hole 34, whereby the package can be hung for display and sales (ref. Patent Documents 1 and X).

[0003] However, the conventional package mentioned above sometimes involves difficulties when taking out the batteries, since the dry batteries are placed in the resin-made container that is attached to the base board. Also, when discarding the package, sometimes the resin portion and the base board need to be separated, which involves troublesome effort (ref. Patent Documents 3 to 8).

Technical Problem

[0004] The present invention was made in view of the above problem, and aims to provide a package which allows for extremely easy removal of a package-subject and extremely easy disposal after the removal of the package-subject, and which is preferable for displaying the package-subject for sale. Technical Solution

[0005] To achieve the above objective, a package of the present invention comprises: a sheet of paperboard for packaging a package-subject including at least one article, the paperboard including: a bottom board having a width corresponding to the thickness of the package-subject; and a front board and a rear board, each extending from fold lines at both width-direction ends of the bottom board; wherein the package-subject is packaged by sandwiching the package-subject between lower sections of the front board and the rear board while the package-subject is being allowed to abut on the bottom board, and by attaching an upper section of the front board to an upper section of the rear board, a window portion for exposing at least a portion of the package-subject is provided at the lower section of the front board; and perforations are formed at least one of fold lines between the front board and the bottom board and between the rear board and the bottom board.

[0006] Based on such a configuration, when removing the package-subject from the package, the package-subject can be taken out from the bottom of the package by tearing the perforations provided at least one of the fold lines between the front board and the bottom board, and between the rear board and the bottom board, therefore, the package-subject can be easily taken out from the package, also, since the package is made of a sheet of paperboard, the materials need not be sorted out for disposal after taking out the package-subject.

Further, by tearing the lines (fold lines) connecting the front board, the rear board, and the bottom board positioned between the front board and the rear board (the upper sections of the front board and the rear board are bonded together), the package after taking out the package-subject is flattened and planate without any additional effort, thus, the package can be discarded trouble-free with its minimum volume, without being bulky, herein, the upper section refers to the section remote from the bottom board, and the lower section refers to the section close to the bottom board.

[0007] Also, since the window portion is provided in the front board at the position corresponding to the package-subject, although the package-subject is packaged only by using a non-transparent paperboard, an article can be displayed for sale in a directly visible fashion, further, since a resin-made sheet is not used, with no emission of toxic substance when combusted for discarding, a contribution can be made for environmental conservation, furthermore, in addition to the perforations at the fold line between the rear board and the bottom board, by providing for example perforations forming an arc from the fold line to the rear board side (ref. reference numeral 19 in FIG. 1), the perforations can be torn just by pressing the arc portion with fingers, therefore, the package-subject can be further easily taken out. The arc portion also renders the torn portion quite neat.

[0008] In the package of the present invention, the window portion is preferably formed so that its lateral width is made substantially the same with the lateral width of the package-subject at the portion corresponding to the upper section of the package- subject, and that the left and right frame portions at that portion of the window portion abut on the left and right end faces of the package-subject, respectively, at the portions thereof corresponding to the upper section of the package-subject, to secure the package- subj ect.

This prevents the package-subject from moving laterally, slipping out from the side faces, and from being misaligned relative to the window portion.

[0009] In the package of the present invention, preferably, notches extending upward from the left and right upper corners of the window portion are provided, and a tongue portion is formed between the left and right notches to press the package-subject in the direction of the rear board and the bottom board.

Thus, with such a flexibly- structured tongue portion formed between the notches at the left and right upper corners of the window portion to press the package-subject, cushion function (adjustability) and shock-absorbing effects can be brought out especially for the upward-downward movement of the package-subject, to secure the package-subject, that is, even with the upward-downward movement of the package- subject, the upper portion of the window portion does not easily break, and the package-subject can be prevented from being slipped out based on this breakage.

Further, by providing the notches cutting in and extending upward from both upper right and left corners of the window portion, the upper end portion of the package- subject can be projected frontward (ref. FIG. 5 and FIG. 6). thus, by allowing the left and right edge portions at the upper left and right corners of the window portion to abut on the left and the right side faces of the package-subject at the upper end thereof, the package-subject can be secured laterally.

[0010] In the package of the present invention, the lateral length of the window portion corresponding to the lower section of the package-subject is preferably shorter than the lateral length of the package-subject.

Based on this, the package-subject can be prevented from slipping out from the window portion, ahead of the front board. [0011] In the package of the present invention, preferably, glue strips and cover plates are provided and connected with fold lines in between. The glue strips to be attached to the front face of the rear board are provided at lateral ends in the lower section of the rear board; and the cover plates are for covering the lateral ends of the package-subject by abutting on lateral ends of the package-subject and the rear face of the front board.

Based on such a configuration, the lateral movement of the package-subject can be prevented further reliably, so that the package-subject can be prevented from slipping out from lateral sides of the package, and by supporting the front board from the rear face side with the cover plates, the strength (durability) of the package is improved as a whole, therefore, the package-subject can be protected from outside impacts. After removing the package-subject, the cover plate may be flattened to make the cover plate parallel with the rear board by unfolding the fold lines between the cover plate and the glue strip. In this way, the cover plate, the glue strip, the front board, and rear board can all be made parallel with each other, so that the whole package can be folded up in a flat fashion, therefore, the package can be discarded with its minimum volume without making it bulky and any trouble at all.

[0012] In the package of the present invention, hanging holes are preferably provided in the upper sections of the front board and the rear board, at positions corresponding to each other.

With these holes, the package can be hung, for example on a hook, therefore, the package-subject can be displayed at stores by hanging, saving display space.

[0013] In the package of the present invention, the package-subject is preferably wrapped in a heat-shrinkable film.

Such wrapping enables a plurality of articles oriented to show the front- face (facing) in advance to be bound together integrally, therefore, individual article in the package can be prevented from being misaligned, and the front-faced orientation can be kept. This gives favorable impression to the consumers of the article.

[0014] In the package of the present invention, perforations are formed preferably, in the front board, extending further upward from the left and right upper corners of the window portion.

With such perforations, the front board can be torn at the upper portion of the window portion, to remove the package-subject, therefore, not only from the bottom side of the package, the package-subject can be taken out from the front side as well, further improving removability of the package-subject.

Advantageous Effects

[0015] The present invention provides a package in which a package-subject can be easily taken out, which is easily discarded after taking out the package-subject, and which is preferable for displaying the package-subject for sale.

[0017] An embodiment of the present invention is described by referring to FIGs. 1 to 6. FIG. 1 is a plan view illustrating an unfolded package in one embodiment of the present invention. FIG. 2 is a perspective view of a package-subject to be packaged in the package of FIG. 1. FIG. 3 is a plan view illustrating steps for packaging the package-subject in the package of FIG. 1. FIG. 4 is a front view of the package of FIG. 1 with a package-subject packed therein. FIG. 5 is a perspective view of the package of FIG. 4. FIG. 6 is an enlarged view of a relevant part of the package of FIG. 4, seeing the portion indicated by X from the side.

[0018] A package 1 of FIG. 1 is a package for packaging a package-subject 20, which includes a plurality of dry batteries 21 oriented to show the front-face (facing) in advance (ref. FIG. 2. in the example shown, four AA size dry batteries disposed side- by-side) wrapped in a heat-shrinkable film (shrink wrap package); and is composed of a sheet of paperboard 2. the paperboard 2 includes a substantially rectangular bottom board 3 having a width corresponding to the thickness of the package-subject 20, and a front board 6 and a rear board 7, each of which extending from fold lines (perforations 5 and 4 to be mentioned later) at both width-direction ends of the bottom board 3. At the fold line between the rear board 7 and the bottom board 3, first perforations 4 extending over the entire length thereof are formed, and at the fold line between the front board 6 and the bottom board 3, second perforations 5 extending over the entire length thereof are formed.

[0019] The front board 6 is divided by a first fold line 10 into an upper section 6a, which is a section remote from the bottom board 3, and a lower section 6b, which is a section close to the bottom board 3. the front board 6 and the rear board 7 are folded at the fold line of the first perforations 4 and at the fold line of the second perforations 5, so as to stand from the plane of FIG. 1, respectively, to attach the upper section 6a of the front board 6 to an upper section (no reference numeral) of the rear board 7. the package- subject 20 is thereby packaged by being sandwiched between the lower section 6b of the front board 6 and a lower section (no reference numeral) of the rear board 7.

In the upper section 6a of the front board 6 and in the upper section of the rear board 7, an aperture 8a and an aperture 8b are formed, respectively, at positions corresponding to each other, so as to form a hanging hole 8 (ref. FIG. 4) when these apertures are brought together to meet each other.

[0020] In the lower section 6b of the front board 6, a substantially rectangular window portion 9 is formed for exposing the package-subject 20 to allow the package-subject 20 to be visible from the outside of the package 1.

The window portion 9 has a slightly shorter longitudinal length than the longitudinal length of the package-subject 20, and lateral width Wa of the upper section thereof corresponding to the upper section of the package-subject 20 (ref. FIG. 3) is substantially equal to width Wb of the package-subject 20. at both lower corners of the window portion 9, substantially rectangular retainers 14 are provided, extending inwardly to the window portion 9. the retainers 14 render the lateral width of the lower portion of the window portion 9 shorter than the lateral width of the corresponding portion of the package-subject 20. the window portion 9 is provided in the front board 6, leaving a certain distance between the lower edge 9a and the fold line (second perforations 5).

[0021] Further, at both upper right and left corners of the window portion 9, notches 12 extending upward are provided, so as to cut in upward, and between the left and right notches 12, a substantially trapezoidal tongue portion 11 is formed. Although not clearly illustrated in the figure, the notches 12 are formed, so that the upper ends thereof are positioned slightly lower than the upper end of the package-subject 20, when the package-subject 20 is being packaged.

[0022] At the lateral ends in the lower section of the rear board 7, substantially rectangular glue strips 16 are provided. The rear board 7 and the glue strip 16 are connected with a fold line 15 in therebetween. The glue strip 16 is to be attached to the front face of the rear board 7 (the plane which is to face the front board 6 when the package 1 is assembled), further, to the side ends of the left and right glue strips 16, cover plates 18 are provided. The cover plate 18 and the glue strip 16 are connected with a fold line 17. The cover plate 18 is to be brought into contact with the lateral ends of the package-subject 20 and the rear face of the front board 6 (the plane which is to face the rear board 7 when the package 1 is assembled) so as to cover the lateral ends of the package-subject 20. The cover plates 18 have the maximum lateral width at the lower portion (the side close to the bottom board 3), and the width decreases toward the upper portion (the side remote from the bottom board 3), being formed like an arc, with its width disappearing at its upper end portion.

At the lower end portion of the rear board 7, third perforations 19 are provided, forming an arc protruding from the fold line at the first perforations 4.

[0023] When packaging the package-subject 20 with the above-described package, as shown in FIG. 3, the package-subject 20 is placed on the front face of the rear board 7, by aligning the lower end of the package-subject 20 with the fold line or the first perforations 4. then, the glue strips 16 are folded at the fold lines 15 over to the front face side of the rear board 7 to be attached thereto, and the fold lines 17 are folded so as to allow the cover plates 18 to stand perpendicular to the front face of the rear board 7. with the cover plates standing, the first perforations 4 at the fold line and the second perforations 5 at the fold line are folded in this order so as to sandwich the package- subject 20 between the lower section 6b of the front board 6 and the lower section of the rear board 7, and the upper section 6a of the front board 6 and the upper section of the rear board 7 are attached so as to allow the aperture 8 a and the aperture 8b to meet.

As shown in FIGs. 4 and 5, the package-subject 20 is thereby packaged, being sandwiched between the lower section of the front board 6 and the lower section of the rear board 7, while abutting on the bottom board 3.

[0024] As shown in FIGs. 5 and 6, since the lateral width Wa of the upper section of the window portion 9 is made substantially equal to the lateral width Wb of the package- subject 20 and the notches 12 are provided at both the left and right upper corners of the window portion 9, the upper end portion of the package-subject 20 slightly projected from the window portion 9 ahead of the front side of the front board 6. thus, the left and right end faces of the upper end portion of the package-subject 20 abut on left and right frame portions of the window portion 9, respectively, so that lateral movement of the package-subject 20 is prevented, therefore, the package-subject 20 is prevented from slipping out from the side faces of the package 1 and from being misaligned relative to the window portion 9 due to lateral movement.

[0025] Additionally, the tongue portion 11 formed between the left and right notches 12 presses the package-subject 20 in the direction of the rear board 7 and the bottom board 3. thus, by forming the flexibly-structured tongue portion 11 between the notches 12 to press on the package-subject 20, the tongue portion 11 can function as a cushion (adjustability) and can bring out shock-absorbing effects especially for the upward-downward movement of the package-subject, and the package-subject 20 can be secured, that is, even with the upward-downward movement of the package-subject, the upper portion of the window portion 9 does not easily break, and the package- subject 20 can be prevented from being slipped out based on this breakage.

[0026] Further, the retainers 14 provided at both lower corners of the window portion 9 abut on the lower section of the package-subject 20, and a slight distance is provided between the lower end of the front board 6 (the position of the fold line at the second perforations 5) and the lower edge 9a of the window portion 9, for such a portion to abut on the lower end portion of the package-subject 20. with such an arrangement, the package-subject 20 is prevented from slipping out from the window portion 9 frontward.

[0027] Also, since the cover plates 18 that are provided and connected to the glue strips 16 to be attached to the front face of the rear board 7 are abutting on both end faces of the package-subject 20, the package-subject 20 is prevented further reliably from moving side-to-side and from slipping out from the side faces of the package-subject 20. also, since arc-formed and curved side edge portions of the cover plates 18 are abutting on the rear face of the front board 6 to support the front board 6 from the rear face side, strength (durability) of the whole package 1 can be improved, therefore, the package- subject 20 can be protected from outside impacts.

[0028] Additionally, with the hanging hole 8 formed by attaching the upper section of the front board 6 to the upper section of the rear board 7, the package-subject 20 can be arranged and displayed at stores by hanging, saving display space.

[0029] The package-subject 20 is shrink wrap packaged, and a plurality of dry batteries oriented to show the front-face (facing) in advance can be integrally bound together. Therefore, individual dry battery in the package 1 can be prevented from being misaligned, and the front-faced orientation can be kept. This gives favorable impression to dry battery consumers.

[0030] For the heat-shrinkable film for shrink wrap packaging the package-subject 20, biaxially-streched PET (polyethylene terephthalate) film is preferably used. The reasons are from the following characteristics of biaxially-streched PET films: 1) excellent dimensional stability and machine applicability; and 2) high modulus of elongation and suitability for secondary fabrication such as printing.

[0031] The surface of the paperboard 2 is preferably coated, for surface decoration and protection, and for reinforcement of the package 1 on the whole, to be specific, any one of water coating, UV coating, and lamination is preferably carried out. [0032] Water coating is a coating using water varnish mainly composed of for example acrylic resin emulsion, and is excellent in resistance to friction. The water coating is low in costs compared with UV coating and lamination, but aesthetically inferior to UV coating and lamination.

UV coating is a coating by UV-cure ink, or a coating by highly glossy UV varnish, and is excellent in resistance to friction, water, and moisture. In terms of costs and appearance, UV coating stands in the middle of water coating and lamination. In the case of UV coating and water coating, unlike coating with vinyl or PP (polypropylene) film, the paperboard can be recycled without peeling off the coating.

Lamination is a coating by attaching a film of plastic such as PP and PE (polyethylene) on the surface of the paperboard 2, and is excellent in resistance to friction, water, moisture, oil, and to weather, and in folding endurance, lamination is the best in terms of appearance, but costs are higher than water coating and UV coating.

[0033] Thus, when taking out the package-subject 20 from the above-described package 1, the portion encircled by the arc- shaped third perforations 19 at the lower end portion of the rear board 7 is pressed by for example a thumb. With the pressing, the third perforations 19 are torn, and then the first perforations 4 that are positioned further from the third perforations 19 are torn, to open the bottom portion of the package 1. thus, the package-subject 20 can be easily taken out from the bottom portion of the package 1. in this way, the tearing can be carried out quite neatly, compared with the case when for example the first perforations 4 and the second perforations 5 are both torn to remove the bottom board 3 from lateral side, therefore, favorable impression can be given to dry battery users.

After taking out the package-subject 20, by stretching out the fold line (5) between the bottom board 3 and the front board 6, and the fold line 17 between the cover plates 18 and the glue strips 16, the cover plates, the glue strips, the bottom board, the front board, and the rear board can be all flattened so that all are in parallel with each other, to fold up the entire package in a flat fashion, therefore, the package can be discarded with its minimum volume without making it bulky and any trouble at all. also, since the package 1 is formed of a sheet of the paperboard 2, there is no need to sort out the materials after taking out the package-subject for discarding the package 1.

[0034] In the package 1, since the window portion 9 is provided in the front board 6 at the position corresponding to the package-subject 20, even though only a non-transparent paper is used for the packaging, the package-subject 20 can be made directly visible for display for sale, also, without using resin-made sheet, no toxic substance is emitted even by combustion, and a contribution can be made for environmental conservation.

[0035] Although the present invention is described above based on Examples, the present invention is not limited to the above examples, and various variations can be made. For example, although the package-subject 20 included four AA dry batteries packaged side-by-side in shrink wrap in the above example, the dry batteries is not limited to AA-type, and the number of the batteries is not limited to four. The battery may be, for example, only one. The form of the dry batteries is not limited to rod-like, and may be a box-type such as 9 V dry batteries, further, the package may be used for stationeries and cosmetics as well and not limited to dry batteries, as long as it can be placed in the package made of a sheet of paperboard. In the case of box-type articles, which do not have orientation problem (facing misalignment), the wrapping may be usual wrapping, instead of shrink wrap package.

The package-subject 20 may be placed so that the longitudinal axis of the dry batteries corresponds with the height direction of the package (vertical setting), although in the above embodiment, the package-subject 20 is placed in the package so that the longitudinal axis of the dry batteries corresponds with the width direction of the package (horizontal setting).

[0036] FIG. 7 shows an example of a package for holding two dry batteries horizontally. FIG. 8 shows a perspective view of a package-subject 2OA, which includes two dry batteries 21 A placed horizontally, to be packaged by the package of FIG. 7. FIG. 9 shows an example of a package for holding two dry batteries vertically. FIG. 10 shows a perspective view of a package-subject 2OB, which includes vertically-set two dry batteries 21B, which is to be packaged by the package of FIG. 9. FIG. 11 shows an example of a package for holding a box-type dry battery (9 V dry battery) vertically. FIG. 12 shows a perspective view of a package-subject 2OC, which includes a vertically-set dry battery (9 V dry battery) 21C to be packed by the package of FIG. 11. in each of the packages in FIGs. 7, 9, and 11, reference numerals are shown for those portions corresponding to the package 1 of FIG. 1.

As shown in FIG. 7, in the package of the present invention, perforations 25 may be formed on the front board 6A so as to further extend upward from the upper left and right corners of the window portion 9A. the package-subject can be taken out by tearing the front board 6A from the upper portion of the window portion 9A. therefore, the package-subject can be taken out from the front side as well, in addition to the side of the bottom board 3A, which further renders the removal of the package-subject easier. Industrial Applicability

[0037] A package of the present invention achieve easy removal of the package-subject, and easy disposal after the removal, and used suitably for displaying and selling the package- subj ect.
