Description

This patent application claims priority from Japanese patent applications Nos. 2000-297251 filed on Sep. 28, 2000 and 2000-395008 filed on Dec. 26, 2000, the contents of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a paper packaging. The present invention, in particular, relates to a blister packaging.

2. Description of the Related Art

A blister packaging is popular for accommodating a product such as a shaver, a battery, a toy, and so on. A box section accommodating the product is conventionally made with clear plastic material, and the box section is adhered to a support member made of paper. The Japanese Patent Laid Open No. Hei. 9-290820 discloses a conventional blister packaging made of paper.

However, the blister packaging including the box section made with clear plastic is, after removing the product, difficult to flatten; thus, it creates a high disposal volume. Furthermore, when a user tries to separate the plastic blister box from the paper support member for recycling, the plastic blister is not recycled because some part of the paper from the support member remains adhered to the plastic blister even after being separated. If the plastic blister with the attached paper is incinerated, harmful gas may be generated. On the other hand, the paper blister packaging disclosed in the Japanese Patent Application Laid Open No. Hei. 9-290820 does not have enough strength on its box section projected from a support member.

DETAILED DESCRIPTION OF THE INVENTION

The invention will now be described based on the preferred embodiments, which do not intend to limit the scope of the present invention, but exemplify the invention. All of the features and the combinations thereof described in the embodiment are not necessarily essential to the invention.

FIGS. 1A and 1B are configuration figures showing a paper packaging 60 according to the embodiment of the present invention. The paper packaging 60 has a support member 10 including an opening 12 , a box section 20 , and a backing sheet 30 . The support member 10 , the box section 20 , and the backing sheet 30 are entirely made from paper. FIG. 1A shows the paper blister packaging 60 before being assembled. FIG. 1B is a perspective view of the paper blister packaging 60 after being assembled. The box section 20 protrudes through the opening 12 of the support member 10 from a back side toward a front side, and the box section 20 is erect. Flaps 24 around the box section 20 contact with edges around the opening 12 . Furthermore, the backing sheet 30 and the support member 10 sandwich the erected box section 20 therebetween.

FIG. 2 shows an example of the box section 20 in detail. FIG. 2A shows a rear view of the box section 20 . FIG. 2B shows a top view of the box section 20 . FIG. 2C is a perspective view of the box section 20 from the front side. The box section 20 has a front face 26 , an upper face 21 , a bottom face 23 , a right side face and a left side face 29 , and four flaps 24 . The front face 26 is connected with the right and the left side faces 29 of the box section 20 ; and the right side face 29 , the front face 26 , and the left side face 29 form a continuous curved surface. The box section 20 is formed like a box. The box section 20 has a large opening on its back face. A product to be accommodated in the box section is packed from the opening on the back face, and the opening is later covered with the backing sheet 30 . For example, the box section 20 accommodates a film cartridge for photography. The box section 20 may accommodate a plurality of film cartridges. Adhering areas 22 are provided on the hatched area on each of the flaps 24 . The flaps 24 are adhered to the support member 10 from the backside of the support member. The backing sheet 30 may be similarly adhered on the backside of the flaps 24 . As described later in detail, the box section 20 may accommodate any kinds of products relating to camera, as because present invention primarily concerns the packaging and not the products to be accommodated therein, as clearly understood when reading the specification as a whole.

FIG. 3 shows an example of the box section 20 before being folded. A chain dashed line depicts a line to be folded in a mountain folding, whereby the two faces of the paper opposite the viewer become closer. A double dashed line depicts a line to be folded in a valley folding, whereby the two faces of the paper facing the viewer become closer. Thus, flaps 25 are folded away from the viewer whereas the flaps 24 are folded toward the viewer. The region where the front face 26 and the side faces 29 connecting one another is processed to form a smooth and continuously curved surface. If the box has a corner, the corner may be collapsed when dropped. Collapsing the corner may be avoided by forming the corner into the continuously curved surface. Furthermore, when the box section accommodates a film cartridge, the curved surface fits a curved outline of the film cartridge. Thus, wearing between an interior surface of the box section 20 and a surface of the film cartridge may be avoided. The region where the front face 26 connects the side faces 29 may form a plurality of predetermined angled ridges fitting with the outline of the product.

FIG. 4 shows a detailed example of the support member 10 and the backing sheet 30 . FIG. 4A shows an example of a support member 10 and an adhering area 22 . The adhering area 22 , indicated as a hatched area in FIG. 4A around the opening 12 on the support member 10 , contacts with the flaps 24 of the box section 20 . On the adhering area 22 , adhesive material maybe previously printed. FIG. 4B shows an example of the backing sheet 30 . Dotted lines around the opening area 36 designate perforations, and a double-chained line depicts the line for the valley folding. Cutting the perforation around the opening area 36 , a large opening is formed on the backing sheet 30 in the region being the back face of the box section 20 before cutting; and the product may be easily removed from the box section 20 . It is preferable to provide the opening area 36 on the backing sheet 30 ; if the opening area 36 is provided on the box section 20 , because the box section 20 is erect, the opening area may be possibly dropped and damaged while distributed. The hatched area around the opening area 36 contacts with the flaps 24 around the box section 20 . Adhesive material may be previously printed on an adhering area 22 . In some cases, the flaps 24 may be adhered to at least one of the support member 10 and the backing sheet 30 . Moreover, the flaps 24 may be adhered to both the support member 10 and the backing sheet 30 . In such a case, the erecting box section 20 is stably fastened against both the support member 10 and the backing sheet 30 by the flaps 24 , therefore the strength of the box section 20 increases. Furthermore, the four corners of the box section 20 are surrounded by the region where the support member 10 , the flaps 24 , and the backing sheet 30 overlaps one another, so that the box section 20 has more strength; therefore even if the paper packaging 60 is dropped, the product accommodated in the box section 20 is protected from the shock of being dropped. In another case, the support member 10 may be put together with at least a part of the backing sheet 30 and adhered to each other. In yet another case, the flaps 24 of the box section 20 may be simply sandwiched by, but not adhered to, both the support member 10 and the backing sheet 30 ; and the support member 10 and the backing sheet 30 are adhered to one another.

FIG. 5 is a flow chart showing an assembling method of the paper packaging 60 . A piece of cardboard is stamped out for preparing the support member 10 including the opening 12 . On a surface of the support member 10 , information such as a name of the product, advertising, and so on may be previously printed (S 100 ). Another piece of cardboard is stamped out for preparing the box section 20 , and folded to form the box section 20 . The cardboard may also be printed with information. The flaps 24 are formed around the box section 20 (S 102 ). The box section 20 is protruded through the opening 12 from the back side of the support member 10 . The flaps 24 contact with an edge of the opening 12 . The box section 20 may accommodate the product in the present step (S 104 ). Next, yet another piece of cardboard is stamped out for preparing the backing sheet 30 . The cardboard may also be printed with information (S 106 ). On the back side of the support member 10 , on which the flaps of the box section 20 are attached, the backing sheet 30 is applied (S 108 ), so that the box section 20 is sandwiched by the support member 10 and the backing sheet 30 . The edge of the opening 12 on the support member 10 is connected with the flaps 24 . The back sides of the flaps 24 may be adhered with the backing sheet 30 . The support member 10 may be adhered with the backing sheet 30 (S 110 ).

FIG. 6 shows another example of the box section 20 having a plurality of grooves provided in the front face 26 . In the present example, the packaging accommodates a plurality of film cartridges. The front face 26 includes a groove formed in front of the region between the plurality of film cartridges 50 . FIG. 6A shows a top view of another example of the box section 20 . As shown in FIG. 6A , the film cartridge 50 is fastened by the groove in the box section 20 . Thus, while being distributed, the film cartridges 50 are protected from being damaged by hitting one another or scraping the surface of the film cartridges 50 with an interior of the paper packaging 60 . FIG. 6B is a perspective view of the box section 20 from the front side. The packaging with compartments divided by the grooves indicates to users that the film cartridges 50 are accommodated in the paper packaging 60 .

FIG. 7 shows another example of the paper packaging 60 before folded. The support member 10 , the box section 20 , and the backing sheet 30 are made from one piece of paper in the present example. The box section 20 , the backing sheet 30 , and the support member 10 are provided in the mentioned order on the aforementioned one piece of paper. For modification, the box section 20 and the backing sheet 30 may be provided on the same piece of the paper; only the support member 10 is provided separately. The chain dashed line depicts a line to be folded in a mountain folding, whereby the two faces of the paper opposite the viewer become closer. The double dashed line depicts a line to be folded in a valley folding, whereby the two faces of the paper facing the viewer become closer. The box section 20 is then folded to form the box.

FIG. 8 shows another example of the paper packaging after being half constructed. The support member 10 , the box section 20 , and the backing sheet 30 made from one piece of paper is halfway constructed in this example. The box section 20 is placed through the opening 12 on the support member 10 . The support member 10 and the backing sheet 30 are folded, put together, and used to sandwich the box section 20 . A back supporting piece 14 is further folded, and connected to the backing sheet 30 . The back supporting piece 14 reinforces a lower edge of the paper packaging 60 by doubling the thickness of the lower edge. Applying this modification, the paper packaging is made from only one component, so that the packaging may be both efficiently and quickly produced. Furthermore, the support member 10 , the box section 20 , and the backing sheet 30 are previously connected, and the adhered region may be narrowed without impairing strength. The packaging applying the present modification may be folded again after opening. After the film cartridge is removed from the paper packaging 60 and photographs are taken on it, the paper packaging 60 may re-accommodate the film cartridge.

In another modification of the present embodiment, at least the box section 20 may be made of plastic material. In the present modification, the box section 20 may be simply sandwiched by, but not adhered to, the support member 10 and the backing sheet 30 . Thus, no paper is attached to the box section 20 after the accommodated product is removed; therefore the packaging is more suitable for recycling than conventional blister packaging.

According to the embodiment of the present invention, without impairing the eye-catching ability of a conventional blister pack, a strong paper blister pack that is highly suitable for recycling is produced. The main material is limited to paper; therefore the assembling apparatus is limited to paper-processing apparatus. When the box section is made of paper, the box section may be flattened by hand after the product is removed. Thus, the paper packaging after use may be entirely flattened and its volume reduced. The paper packaging after use may be conveniently recycled. The paper packaging is suitable for both recycling and incineration because the packaging leaves no mixed material after use. Therefore the paper packaging has a lower environmental impact than the conventional blister pack.

When the paper packaging applying the present embodiment accommodates the film cartridges for photography, the film cartridge for photography is sealed in a moisture barrier material packaging such as an aluminum evaporated plastic film packaging, then accommodated in the paper packaging according to the present embodiment. The moisture barrier material may be incinerated without generating harmful gas when proper material is selected. When the moisture barrier packaging of the film cartridge for photography is provided as described above, the entire packaging, including both the paper packaging and the aluminum evaporated film packaging is suitable for incineration.

A hatching applied on the side face 24 of the box section 20 or the curved surface including the front face 26 and the side faces 29 in FIG. 1 A and FIG. 1B , FIG. 2C , FIG. 6B , and FIG. 8 is applied for stereoscopic effect.

Although the present invention has been described by way of exemplary embodiments, it should be understood that those skilled in the art might make many changes and substitutions without departing from the spirit and the scope of the present invention which is defined only by the appended claims.

For example, though the present embodiments refer the film cartridges for photography that are accommodated in the box section of the packaging. However, it is not limited thereto or thereby. According to the present invention, the box section may accommodate any product relating to camera such as, a camera body itself including permanent or disposable camera, a stack of photo papers, photo albums, bottles for photo developer, recording medium such as memory, optical disk, magnetic disk, magnetic tape and smart medium, camera accessories such as casing, strap, application software, PC card adopter, battery charger, flush pass, image card reader, battery with or without charger, consumables for printer, word processor or copying machine such as ink cartridge, ink ribbon, seal sheets. The camera may include any digital or analog camera, still or movie camera. Further, the film cartridges embodied in the present specification may also include various kinds of films such as, for example, for APS, 135 film, 110 film, 220 film, instant film or other cut film. As is apparent above, the present invention primally concerns a packaging and not the product to be accommodated therein, and any products relating to camera may be accommodated by the box section of the packaging according to the present invention.
