Description

  The present invention relates to a packaging container. More specifically, the present invention is not limited to packaging a product, and the area of an information display surface for displaying meaningful information to a purchaser such as a consumer can be expanded. Is concealed at the time of shipment, and the information display surface can be exposed at the time of sale or purchase, and after the packaged product has been taken out, the product or its used product that is scheduled to be returned will be returned. Or can be packaged with items that have been sent from the shipper, such as mailed items, such as various products, and the used items or other items can be stored after the items have been removed. The present invention relates to a packaging container that can be sent to, for example, mailed to.

  Conventionally, products have been packaged in, for example, paper packaging containers and distributed in the secondary market. Consumers and other purchasers in the secondary market used to purchase their products together with their packaging.

  The surface area of the packaging container is not changed at the time of shipment, sale, or purchase. For example, when the packaging container is a rectangular box, the commodity is shipped in a state in which the commodity is accommodated in the box, and the packaging container is in the same state as at the time of shipment. Therefore, it can be said that the packaging container has the same surface area at the time of shipment and at the time of sale. Moreover, when purchasing goods, the goods are purchased with the packaging container. When the product is used, the sealed portion in the packaging container is opened to take out the content product. The packaging container after opening the sealed part has the surface area of the packaging container increased only by the opened part, but the surface area of at least the panel part in the packaging container has not increased.

  By the way, when displaying the packaging container which accommodated goods in a shop front, there exists a packaging container which requires the part (henceforth a "hanger part") called a hanger in the packaging container. When this packaging container is a rectangular parallelepiped, for example, the panel portion protrudes from the rectangular parallelepiped. When mass transporting packaging containers containing products, it is necessary to pack packaging containers that are rectangular parallelepipeds as compactly as possible into a transport container such as a cardboard box. When trying to pack the packaging containers efficiently and in large quantities, there is a problem that the packing operation becomes complicated and time consuming. Here, there is a demand for a packaging container that does not have a protruding portion at the time of shipment and transportation, and that can easily form a protruding portion such as a hanger portion so that it is convenient for store display at the time of store display. . However, at present, such a convenient packaging container is not found in the market.

  Various information about the product is printed on the surface of the packaging container containing the product. The amount of various information printed on the surface of the packaging container depends on the surface area of the packaging container. There is often a need to disclose a larger amount of information related to the packaging container at the time of store display than the amount of information described on the surface of the packaging container. In that case, it is conceivable that separately provided information providing means such as a sticker, a standing signboard, a card or the like is attached to the packaging container containing the merchandise, and it is also executed at an actual store. However, it is very complicated to create information providing means to be attached to the packaging container each time, arrange it next to the packaging container, and connect the packaging container. However, it is difficult to adopt the idea that a protruding portion such as a sheet or a plate is formed in advance on the packaging container and various information is printed on the surface of the protruding portion. This is because, as described above, it is convenient for transportation and inventory preservation that the packaging container has a simple shape as much as possible, for example, a rectangular parallelepiped, a cube, and a cylinder, but there is a protruding portion in addition to the simple shape. This is because the packaging container is inconvenient for transportation and stock preservation. Here, there is a demand for a packaging container that does not have a protruding portion at the time of shipment and transportation, and does not require provision of an information providing means different from the packaging container at the time of store display. However, at present, such a convenient packaging container is not found in the market.

  In order to improve sales of products in packaging containers, sales promotion activities are essential. As one of the sales promotion activities, gifts can be given. The purpose of providing a free gift is to increase the number of purchasers who purchase the product for a free gift item. However, there is a limit to the provision of free gifts as a motivation for purchasing products so that an increase in product sales can be realized. If a free gift with a value greater than the product to be purchased is provided free of charge, the sales volume of the product will increase dramatically, but such a free gift cannot be provided for economic reasons. In that case, it is motivation to shoot directly that contributes to sales promotion. For example, if a lottery is added to the packaging container of the product, the number of purchasers who purchase the product for the lottery is expected to increase dramatically. However, it is not possible to attach a lottery ticket with current packaging containers. This is because the lottery must be kept secret when the product is packaged. It is conceivable to store a winning lot together with the product in the packaging container, but it is necessary to create a winning lottery and a winning lottery separately from the packaging container and randomly store them in the packaging container, which is a cumbersome work. It will be forced and it is not realistic.

  In addition to the problems described above, the packaging container also has the following problems.

  The purchaser who purchased the product together with the packaging container took out the product from the packaging container when using the product or the like, and then discarded the packaging container. In addition, after using the product, if it is determined that the product is unnecessary, the product is usually discarded.

  If the product is made of plastic, for example, the plastic product is discarded because the plastic product has been used. It is clear that

  Also, if the packaging container is made of paper, the pulp that is the raw material of the paper is made from wood, so simply disposing of the opened paper packaging container is a waste of resources, as is the case with plastic. Become.

Discarding or discarding used plastic products has an adverse effect on the environment because plastic is hardly decomposable. Also, incineration of plastic products will cause the production of environmental hormones such as dioxins, leading to deterioration or destruction of the environment. Further, if the paper packaging container after opening is simply discarded or incinerated, not only will the forest, which is the raw material of paper, be depleted, but severe environmental problems such as global warming due to a decrease in the forest area will occur.

  Therefore, from the viewpoint of environmental protection in recent years, it is necessary to collect as much as possible the product taken out from the packaging container and reuse it as a resource after use, and also about the paper packaging container after opening, It is hoped that this will be recovered and reused to protect forest resources.

  In practice, however, it is cumbersome for the purchaser of the product to provide the packaging containers to the resource recovery company one by one, and it is also complicated to provide the used plastic products one by one to the resource recovery company. Therefore, it is only necessary to dispose of the opened packaging container and the used product contained in the packaging container without sending it to the resource recovery company, and the resource recovery will be improved. There wasn't.

  A technique for systematically collecting used products and packaging containers has not been proposed yet.

  It is an object of the present invention to provide a packaging container having not only a packaging function for packaging products but also an information disclosure function. Another object of the present invention is not only to have a product packaging function, but also to be able to wrap and return the used product when the product is used, thereby collecting and using the used packaging container. An object of the present invention is to provide a packaging container capable of exhibiting the function of collecting used products. Still another object of the present invention is to provide not only a product packaging function, but also a packaging container for transporting which can be used to accommodate the contents and send them to other places after the contents are taken out. The purpose is to do.

As means for solving the problems,

  The packaging container according to the present invention is formed so that the upper polymerization portion can be separated from the lower polymerization portion so as not to be completely separated, and therefore, when the upper polymerization portion is separated from the lower polymerization portion, the surface area of the packaging container is expanded. Can do. Therefore, if information can be written or described on the exposed surface of the upper overlapping portion and / or the exposed exposed surface of the lower overlapping portion, various information can be expressed on the exposed surface. For example, an exposed surface newly formed by the surface area expansion is used as an information disclosure surface, and various information such as product information, lottery information, information on a seller and / or manufacturer, etc. is described on the information disclosure surface. Can be expressed. Therefore, this invention can provide a multifunctional packaging container having a new information providing function in addition to the packaging function of simply wrapping merchandise.

  In the packaging container according to the present invention, the upper overlapping portion is a hanger having a mooring opening, so that it is not necessary to provide a hanger protruding from the packaging container at the time of manufacture or shipment, and the storefront. By forming a hanger at the time of display, it is possible to display a product hung by the hanger. Therefore, according to the present invention, it is possible to provide a packaging container that does not have a protruding portion such as a hanger at the time of shipment, and therefore can pack a large amount of packaging containers containing commodities into a predetermined transport container in a compact manner.

The upper overlapping portion is peeled off from the overlapping portion of the upper overlapping portion, the unsealed portion is sealed with the upper overlapping portion, and the product can be sent together with the packaging container to a predetermined location. According to the packaging container according to the present invention, it is possible to collect used products and packaging containers in predetermined places or departments, and reuse the used products and used packaging containers as new resources after collection. Can do. Therefore, the packaging container of this invention is an article suitable for environmental protection.

  In addition, according to the packaging container according to the present invention, if the contents stored in the zippered bag are accommodated in the opened packaging container, there is a risk of liquid leaching, leakage, or infiltration from the contents. Regardless, the liquid generated from the contents during the transportation does not leak out of the packaging container and can be transported safely. In addition, in the address description column, if a transport destination, for example, a mailing address is determined in advance, the address may be described in the address description column by printing or the like.

In addition, when information meaningful to the purchaser and the seller is printed on the exposed surface 60 of the lower overlapping portion 54 exposed by standing the hanger portion 59, the information is printed on the outer surface of the packaging container 50 at the time of shipment. A larger amount of information than information can be provided.

(Second form)
FIG. 2 shows a second embodiment which is an example of the present invention. As shown in FIG. 2, the packaging container 50 </ b> A can store commodities therein, like the packaging container 50 according to the first aspect, and includes a front part 61, a back part (not shown), It has a rectangular parallelepiped shape including a right side surface portion (not shown), a left side surface portion 62, an upper surface portion 53, and a bottom surface portion (not shown).

  This packaging container 50A is different from the packaging container 50 according to the first aspect in that the upper overlapping part 63 forming the front part 61 starts from a position at a predetermined height from the lower end of the front part 61. Slightly extends in the vertical direction, then draws an S-curve and heads to the right end of the front portion 61, goes vertically at a predetermined distance from the right end of the front portion 61, and extends from the upper end of the front portion 61 to the upper end at a predetermined position. In parallel, the direction is changed at a predetermined distance from the left end of the front portion 61 and descends downward. A curve that is symmetrical with the S-shaped curve is drawn, and a position that is symmetrical with respect to the starting point is set as the arrival point. The perforation is formed, and a valley fold line is formed so as to connect the starting point and the arrival point at the perforation, and the cause is surrounded by the breaking line formed by breaking the perforation. 64 does not become a hanger part, it is an advertising piece by printing information on the back side surface thereof, on the exposed surface 66 of the lower overlapping part 65 exposed by causing the trigger piece 64 This means that the exposed surface 66 is an advertising surface because the information is described.

  Similar to the packaging container 50 of the first aspect, the packaging container 50A having such a structure is formed in a substantially rectangular parallelepiped with no protruding portion at the time of shipment. Therefore, a large number of the packaging containers 50A in which commodities are accommodated can be packed in a transport container in a compact manner. When the packaging container 50 is displayed at the storefront, the raising piece 64 is caused to be exposed, the advertising surface formed on the back side surface is exposed so as to hang from the front portion 61, and the exposed surface 66 in the lower overlapping portion 65 is formed. The advertisement surface that is exposed and formed on the exposed surface 66 can be displayed as an advertisement.

  In FIG. 2, the trigger piece 64 is caused to hang from the front portion 61, but this trigger piece 64 causes the upper overlapping portion forming the front portion 61 to be exposed to expose the back surface. As long as it can be utilized as a description surface, various aspects can be taken.

  For example, as shown in FIG. 3, the upper overlapping portion 63 that forms the front portion 61 of the packaging container 50 </ b> B has a perforation to form a raising piece 64, and one end of a valley line parallel to the lower end edge of the front portion 61. Is defined as a starting point, extending vertically from the starting point, bent horizontally near the upper edge of the front part 61, and descending at a predetermined position of the front part 61 to reach the other end of the valley line. Alternatively, as shown in FIG. 4, a valley line 67 may be formed in the central portion of the raising piece 64, and the raising piece 64 may have a gable shape having the valley line 67 as a ridge.

  Further, as shown in FIG. 5, a perforation can be formed so that the raising piece 64 can be caused by being bent at a valley fold line 68 parallel to the right end edge of the front portion 61.

  In FIG. 2, FIG. 4 and FIG. 5, information such as advertisements for products is described on the exposed surface of the lower overlapping portion exposed by causing the raising piece 64. Further, as shown in FIG. 3, a lottery is written on the exposed surface of the lower overlapping portion exposed by causing the raising piece 64.

Part 121 is formed.

The interval H ₁ between the valley line 147 and the valley line 148 is the sum of the length H ₂ from the short side 126B to the valley line 147 and the length H ₃ from the mountain line 130D to the extension line of the mountain line 132A. Designed to be substantially the same.

  The insertion side forming cut 149 includes a curved cut 149A that is curved so as to protrude downward in FIG. 21, and a bent linear cut 149B that is formed by bending inward at both ends of the curved cut 149A. Formed in preparation. When the portion surrounded by the insertion edge forming cut 149 is raised, the insertion piece 150 is formed.

  As shown in FIG. 21, on the other hand, the cut length H4 of the insertion piece cut 138 is designed to be slightly longer than the length H5 between both ends of the curved cut 149A.

  The developing plate 129 formed as described above is assembled into the packaging container 120 as follows, and the contents are stored.

  Bending lines 126D, 130A, 130B, and 131A are bent into mountain folds, the back surface of the upper overlapping portion 126 is overlapped on the surface of the lower overlapping portion 132, and the lower overlapping portion 132 and the upper overlapping portion 126 are integrated with an adhesive. The front part 121 is formed by bonding. Thereby, a cylindrical body having both ends opened is formed. The mountain fold line 122B is fold-folded so that the opening on the bottom surface side first overlap margin 140B is closed, and the mountain fold line 131C is fold-folded to form the bottom surface side second overlap margin 141B on the cylindrical body. Close the opening. The bottom surface is formed by combining the first bottom surface portion forming piece 135 and the second bottom surface portion forming piece 136 so as to overlap the bottom surface side first overlapping margin 140B and the bottom surface side second overlapping margin 141B. Thus, a bottomed cylindrical body having an opening at one end is formed. After the contents, for example, goods are received from the opening, the upper surface side first overlap margin 140A and the upper surface side second overlap margin 141A are bent so as to close the opening, and then the upper surface side first overlap margin 140A and the upper surface side are folded. The upper surface portion 137 is overlapped on the overlap margin 141A, and the insertion piece 139 is inserted into a gap formed by the mountain fold line 137C and the front side surface of the second hanger piece 134 in the insertion piece cut line 138. Thereby, the flat plate-shaped rectangular parallelepiped packaging container 120 provided with the hanger 124 is completed.

  In the packaging container 120 thus completed, when the perforation 127 is broken, an extraction portion fixing piece 151 that cannot be separated from the upper overlapping portion 126 is formed at the valley fold line 147.

  As shown in FIG. 22, the take-out portion fixing piece 151 fixes the upper surface portion 137 that is the take-out portion so that it cannot be opened. That is, as shown in FIG. 21, valley fold line 147 is valley-folded so that the flat portion from valley fold line 147 to valley fold line 148 is brought into close contact with the surface of first hanger piece 133, and valley fold line 148 is valley-folded and taken out. One end of the portion fixing piece 151 is inserted into the gap between the longitudinal edge of the upper surface portion 137 formed by the mountain fold line 137C in the packaging container 120 and the second hanger piece 134 with which the longitudinal edge of the upper surface portion 137 abuts. The insertion piece 150 is inserted into the insertion piece cut line 138. When the insertion piece 150 is inserted, the length of the insertion piece cut 138 is slightly smaller than the length between both ends of the insertion piece cut 138, so that the insertion piece 150 is resistant to insertion into the insertion piece cut 138. Although there is a feeling, a slight force is applied to insert the insertion piece 150 into the insertion piece notch 138.
