Description

Technical Field

[0001] The present invention relates to a packaging box that houses a sheet material and bottle-type products such as beverage containers, and uses the sheet material as a lid to cover the opening top surface of the box body.

Background Art

[0002] Beverage containers transported from a beverage manufacturer to a retail store are housed in cardboard packaging boxes that can accommodate a plurality (such as 24) of them. (Hereinafter, bottle-type products that are housed in a packaging box during transportation, like the above beverage containers, are also referred to as "accommodated objects" below).

[0003] Thus, until the stage of arranging and displaying bottle-type accommodated objects at the storefront of a retail store, etc., starting from the factory shipment of a beverage manufacturer, they are distributed and stored and managed in a packaged form with the accommodated objects contained.

[0004] In recent years, for accommodated objects housed in cardboard boxes, especially for products using PET bottles, a label-less product form that eliminates the outer label film (a shrink film printed with product names, product information, and decorative information) has been increasingly adopted.

[0005] The aims of the label-less product form are as follows. That is, when conventional PET bottle products are discarded after being emptied, the outer label film and the bottle body are separated. However, compared to the bottle body that is recycled, there is the trouble of treating the label film as waste, which is in line with the reduction of waste for environmental conservation. Therefore, as described above, for bottle-type products using PET bottles, those without using the label film have come to be distributed.

[0006] On the outer label film wrapped around the body of a normal bottle-type product, in addition to product information and manufacturer information, various display information including decorative information such as logos and decorations is provided by printing.

[0007] By the way, for bottle-type products, the above information can also be displayed using a neck label.

[0008] For example, as shown in Patent Documents 1, 2, and 3, a neck label can be used which has the display information on a small label and an annular portion for passing through the neck of a bottle-type product, or a neck label can be used which has a slit made in a small label with the display information on it that can pass through the neck of a bottle-type product.

[0009] Then, a neck label is attached to each individual container of the bottle-type product before it leaves the factory, and these are then packed into the packaging box for shipment. Alternatively, when store employees take the products out of the packaging box at convenience stores and other retailers, they can attach the label to each individual container, allowing them to check the displayed information.

[0010] Furthermore, as shown in Patent Document 4, sets of four or six items are bundled together with a paper strip (paper pack), and these bundled sets are then placed in a packaging box.

[0011] In such cases, it is possible to include display information such as product information, producer information, logo, and decorative information on the paper band, so that each individual container can be label-free. [Prior art documents] [Patent Documents]

[0012] [Patent Document 1] Utility Model Registration No. 3235206 Gazette [Patent Document 2] Japanese Patent Publication No. 2020-095158 [Patent Document 3] Japanese Patent Publication No. 2021-173946 [Patent Document 4] Patent No. 6608641 [Overview of the project] [Problems that the invention aims to solve]

[0013] When a neck label is attached to each individual bottle to create a product form that holds all the information together, as mentioned above, the neck labels would be attached to the bottle-type products before they leave the factory and then packaged into a box, or the retailer would attach the neck labels to the bottle-type products as they are removed from the box.

[0014] However, if neck labels are attached to the bottle-type products before they leave the factory, there is a problem in that each individual product must be inspected to ensure that a neck label is attached in order to maintain the quality of the products before shipment. In addition, there is a risk that the neck labels may be damaged or lost during the distribution process from the factory to the retail store.

[0015] Furthermore, when retailers attach neck labels, convenience stores and other retailers display and sell a wide variety of bottle-type products, which creates a cumbersome process where retailers must check whether the information on the neck label corresponds to the bottle-type product.

[0016] Furthermore, in retail stores, in addition to the method of removing each contained item from the packaging box and arranging them one by one on the designated sales area (shelf), there is also a sales method in which a set of contained items bundled together in the aforementioned paper band is removed from the packaging box and displayed in the bundled state. As mentioned above, by providing display information on the paper band, it is possible to match the set of contained items with the display information, but when the set of contained items is transported to the retail store, the contained items end up being double-packaged in the paper band and the packaging box, and the paper band itself is unnecessary when each contained item is displayed individually.

[0017] Therefore, when retailers or consumers unpack the contents, there is a problem in that the amount of packaging material discarded increases by the amount of paper band used.

[0018] Therefore, in view of the above circumstances, the present invention aims to enable a sheet-like member having display information, similar to a conventional label film, to be easily attached to each of the objects to be contained in a packaging box, or to each of a plurality of objects to be contained grouped together and the groups of such grouped objects even when the groups are stored in the packaging box in multiple sets. Another object is to form a sales form in which the display information can be easily confirmed from each of the objects to be contained and from each of the groups of the grouped objects.

[0019] Another problem to be solved by the present invention is to provide a sheet material and a packaging box that can easily display a set of objects to be contained (e.g., beverage containers) contained in a packaging box in a grouped state, can also adopt a mode of selling each object to be contained individually, and can reduce the amount of packaging materials to be discarded.

Means for Solving the Problems

[0020] (The invention of claim 1) The present invention has been made in consideration of the above problems, and is a sheet material used as a lid portion of a packaging box for housing a plurality of objects to be contained in an array state in a box main body portion, and can be overlaid on the opening top surface of the box main body portion of the packaging box. It comprises a top wall panel and a side wall panel that can be overlaid on the side surface of the box main body portion, The top wall panel has a minimum unit section corresponding to each object to be contained in the box main body portion, Each of the minimum unit sections is provided with an object insertion portion through which the object to be contained can be inserted, It has a cut-out area portion that includes at least one of the minimum unit sections and can be cut out from a portion of the top wall panel, A sheet material is provided, characterized in that an information display portion is provided on the surface on the upper surface side of the top wall panel in the cut-out area portion, to solve the above problems.

[0022] (Invention of Claim 3) In addition, in the above invention, in the top wall panel, it is possible that each of the above minimum unit compartments is formed as the cutable region portion.

[0023] (Invention of Claim 4) In addition, in the above invention, it is possible that the cutable region portion includes a plurality of the above minimum unit compartments.

[0024] (Invention of Claim 5) In addition, in the above invention, it is possible that an adhesive portion capable of bonding the side wall panel to the side surface of the box body portion is provided at a portion on the bottom side of the packaging box when the side wall panel is overlapped with the side surface of the box body portion.

[0025] (Invention of Claim 6) In addition, in the above invention, an adhesive portion capable of bonding the side wall panel to the side surface of the box body portion is provided at a portion on the bottom side of the packaging box when the side wall panel is overlapped with the side surface of the box body portion. It is possible that separation means for separating the side wall panel into the bottom side and the top side of the packaging box is provided at a portion on the top side of the packaging box with respect to the adhesive portion.

[0026] (Invention of Claim 7) And another invention provides a packaging box that houses a plurality of containers in a box body portion with an open top surface in an arranged state, includes the sheet material according to any one of Claims 1 to 5 attached so as to cover the open top surface, and has the container insertion portion of the sheet material disposed above the container, thereby solving the above problems.

[0027] (Invention of Claim 8) Furthermore, in the above invention, the adhesive portion of the side wall panel in the sheet material can be adhered to the side surface of the box body.

[0028] (Invention of Claim 9) Furthermore, in the above invention, it is possible to provide a handle on the side of the box body.

[0029] (Invention of Claim 10) Furthermore, in the above invention, the side wall panel of the sheet material may be provided with a notch that exposes the handle to the outside.

[0030] (Invention of Claim 11) Furthermore, in the above invention, the box body comprises a bottom wall plate, a front wall plate and a rear wall plate that are bent upward in a continuous manner with two opposing sides of the bottom wall plate, inner side wall flaps that are connected to two sides of the front wall plate and two sides of the rear wall plate and bent in a direction along the opposing direction of the front wall plate and the rear wall plate, and outer side wall flaps that are bent upward in a continuous manner with another pair of opposing sides of the bottom wall plate and are adhered to the inner side wall flaps of the front wall plate and the inner side wall flaps of the rear wall plate. The end of the side wall panel of the sheet material on the bottom side of the box body can be positioned to cover the upper end of the outer side wall flap of the box body, or to be aligned with the upper end of the outer side wall flap. [Effects of the Invention]

[0031] (Effects of the invention of claim 1) According to the invention of claim 1, the sheet material consists of a top wall panel that can be superimposed on the top opening of a box body that houses a plurality of contents arranged in a row, and a side wall panel that can be superimposed on the side of the box body.

[0032] In this sheet material, the top wall panel has a minimum unit section corresponding to each contained object. Each minimum unit section is provided with a contained object insertion section through which a contained object can be inserted, and there is also a cuttable area that can be cut out from the top wall panel portion, including at least one minimum unit section. An information display section is provided on the upper surface of the top wall panel in the cuttable area.

[0033] By attaching this sheet material to the box body to create a packaging box, a packaging box is obtained that can transport and store items inside while protecting them.

[0034] Furthermore, in retail stores and other locations, by separating and pushing down the desired cut-out area from the top wall panel, and passing the top or neck of the object to be contained through the object insertion section of the smallest unit compartment, the information display unit can be integrally combined with the object covered by the cut-out area.

[0035] The combination configuration is not limited to combining an information display unit with each individual container. For example, multiple minimum unit sections form a continuous cut-out area, and by passing containers through the container insertion section in this cut-out area, a group of multiple containers can be obtained. Furthermore, a product configuration can be selected in which an information display unit is integrated into this group of multiple containers.

[0036] Furthermore, when displaying a set of contained items bundled together, there is no need to prepare a separate paper band (paper carton) for the set of contained items in addition to the packaging box, which has the effect of reducing the amount of packaging material that is discarded.

[0037] (Effects of the invention of claim 2) According to the invention of claim 2, since the top wall panel of the sheet material is provided with multiple cuttable areas, in a storage box in which the sheet material is attached to the top opening of the box body, it is possible to select and push down the cuttable areas in the top wall panel.

[0038] Furthermore, since the information display section in a cut-out area of ​​the top wall panel can be easily integrated with the container that corresponds to the container insertion section in this cut-out area, multiple bundles of containers can be created from a single sheet material, and these bundles can be displayed and sold as a single product.

[0039] (Effects of the invention of claim 3) According to the invention of claim 3, the smallest unit section corresponding to each individual contained object is defined as a cut-out area. Therefore, by attaching the sheet material to the box body to form a packaging box, the small information display components are attached to the packaging box in a way that corresponds to each of the contents it contains, at the time of factory shipment. Therefore, this eliminates the need to check whether or not each container has a neck label attached before it leaves the factory.

[0040] (Effects of the invention of claim 4) According to the invention of claim 4, the cuttable region includes a plurality of minimum unit sections. As the cuttable area has multiple minimum unit sections, the cuttable area is equipped with multiple insertion points for housing objects. By passing housing objects through these insertion points, a single unit can be obtained that combines multiple housing objects. Furthermore, this allows for the selection of a product form in which an information display unit is integrated with this unit of housing objects.

[0041] (Effects of the invention of claim 5) According to the invention of claim 5, the process of attaching the sheet material to the box body is simplified.

[0042] (Effects of the invention of claim 6) According to the invention of claim 6, in a packaging box in which a sheet material is attached to the box body, the opening at the top of the box body, which is sealed by the top wall panel, can be opened by dividing the side wall panel of the sheet material into upper and lower halves, and the operation of dividing the side wall panel into upper and lower halves can be performed without being affected by the adhesive portion between the side wall panel and the box body, and the side wall panel can be easily divided into upper and lower halves.

[0043] (Effects of the invention of claim 7) According to the invention of claim 7, the sheet material is attached to the box body to form a packaging box, which can transport and store an object to be contained inside while protecting it.

[0044] Furthermore, in retail stores and the like, the desired cut-out area can be separated from the top wall panel and pushed down, and the top or neck of the object to be contained can be passed through the object insertion section of the smallest unit compartment, thereby allowing the information display unit to be integrated with the object covered by the cut-out area.

[0045] In terms of combination forms, it's not limited to combining an information display unit with each individual container. For example, multiple minimum unit sections can form a continuous cut-out area, and by passing containers through the container insertion section in that cut-out area, a group of containers can be obtained. Furthermore, it offers the advantage of being able to select a product form in which an information display unit is integrated into this group of multiple containers.

[0046] Furthermore, when displaying a set of contained items bundled together, there is no need to prepare a separate paper band (paper carton) for the set of contained items in addition to the packaging box, which has the effect of reducing the amount of packaging material that is discarded.

[0047] (Effects of the invention of claim 8) According to the invention of claim 8, the attachment of the sheet material to the box body is secure, eliminating the problem of the sheet material coming off during distribution or storage of the packaging box.

[0048] (Effects of the invention of claim 9) According to the invention of claim 9, the spear body has a handle on its side, making it easy to carry the packaging box during distribution.

[0049] (Effects of the invention of claim 10) According to the invention of claim 10, there is a handle on the side of the spear body, eliminating the need to consider the strength of the sheet material when forming the handle. This has the effect of broadening the range of materials that can be selected for the sheet material.

[0050] (Effects of the invention of claim 11) According to the invention of claim 11, the side wall panel of the sheet material that overlaps the inner flap side of the box body covers the upper end of the outer flap, and the end of the side wall panel of the sheet material on the bottom side of the box body is positioned to protrude from the upper end of the outer flap.

[0051] Therefore, even if there is a gap between the paired inner side flaps on the main body of the box, the gap between these inner side flaps is concealed from view, thus preserving the appearance of the packaging box. Furthermore, it has the excellent effect of preventing improper handling, such as using the gap as a finger grip to lift the packaging box. [Brief explanation of the drawing]

[0053] Next, the present invention will be described in detail based on the illustrated embodiment. In the figure, 1 is a packaging box according to the present invention, and the packaging box 1 consists of a box body 2 made of corrugated cardboard, assembled from blanks, with the required overlapping portions glued together and having an open top surface 2a, and a sheet material 3 that is attached by overlapping it so as to cover the open top surface 2a of the box body 2, and by folding down the four panel portions and overlapping and gluing them to each of the four sides of the box body 2 (first side surface 2b, second side surface 2c, third side surface 2d, fourth side surface 2e).

[0054] (Box body) The box body 2 is a box-shaped body having an open top surface 2a, formed by having the sides rise up from the four sides of the bottom surface 2f. As shown in Figure 2, the front wall plate 5 and the rear wall plate 6 are connected to a pair of opposing sides of the rectangular bottom wall plate 4, and are bent upward in the vertical direction of the box. The first side surface 2b and the second side surface 2c of the box body 2 are formed by these front wall plate 5 and rear wall plate 6.

[0055] Furthermore, side wall flaps 7 are provided on two sides of the front wall panel 5, bent in a direction aligned with the opposing direction between the front wall panel 5 and the rear wall panel 6, and side wall flaps 8 are provided on two sides of the rear wall panel 6, similarly bent in a direction aligned with the opposing direction between the front wall panel 5 and the rear wall panel 6, and positioned to abut against the side wall flaps 7.

[0056] Furthermore, side wall outer flaps 9 are attached in series to another pair of opposing sides of the bottom wall plate 4, which forms the bottom surface 2f. These flaps are folded upward in the vertical direction of the box and are overlapped and glued to the outer surfaces of the aforementioned side wall inner flaps 7 and side wall inner flaps 8, which are positioned to abut against each other. By arranging the outer side flap 9 from the outside to overlap with the inner side flaps 7 and 8 on the two sides of the side wall, the third side 2d and fourth side 2e of the box body 2 are formed.

[0057] As shown in the diagram, the outer side flap 9 does not cover the entire outer surface of the inner side flap 7 and inner side flap 8, but rather is a flap that has a height from the side edge of the bottom wall plate 4 to the middle level of the box.

[0058] The main body of the box 2 is made of, for example, corrugated cardboard, and only needs to have enough strength to prevent damage during normal handling of the packaging box 1 during transport. Furthermore, as this part will be equipped with a handle as described later, it only needs to have enough strength to prevent damage when the handle is used, and the material is not limited.

[0059] (Sheet material) The sheet material 3 consists of a rectangular top wall panel 10 that can be placed over the opening top surface 2a of the box body 2 to cover the opening top surface 2a, a first side wall panel 11 and a second side wall panel 12 that are connected to two opposing sides of one pair of top wall panels 10 and are attached to the first side surface 2b and the second side surface 2c of the box body 2, and a third side wall panel 13 and a fourth side wall panel 14 that are connected to another pair of opposing sides of the top wall panel 10 and are attached to the third side surface 2d and the fourth side surface 2e of the box body 2.

[0060] The material of sheet material 3 is not particularly limited, but examples include water-resistant paper, corrugated cardboard, and plastic sheets.

[0061] (Minimum unit area) In the figure, reference numeral 16 indicates the smallest unit compartment corresponding to the contents 15 housed in the box body 2. In the top wall panel 10 of the sheet material 3, which is attached to the box body 2 and overlaps the top surface 2a of the opening, multiple smallest unit compartments 16 are arranged to match the arrangement of the contents 15 housed inside the box body 2. In this embodiment, one smallest unit compartment corresponds to one contents 15.

[0062] (Insertion section for the body to be contained) Each of the smallest unit compartments 16 is equipped with a container insertion section 17 that can pass through the top or neck of the container 15 and engage with the container 15. In this embodiment, the container 15 is depicted in the figure as a bottle with a cap at the top, but it can also be a synthetic resin bottle filled with beverage, a handheld bottle can, or a glass bottle. The configuration of the container insertion section 17 through which the container 15 passes is not particularly limited, but as an example, if the container 15 is a bottle-type product as shown in the figure, it can have a structure comprising a substantially circular outline and a plurality of tabs arranged inside this outline and aligned circumferentially along the outline.

[0063] Here, before the object to be contained 15 is inserted into the object to be contained insertion section 17, the individual tabs are positioned face down (flat with respect to the sheet material 3) with their contour lines facing radially inward into the object to be contained insertion section 17.

[0064] (Removable area) The top wall panel 10 has multiple cuttable areas 19, which are surrounded by separation lines 18 that are perforated to cut the sheet material 3. The cuttable area 19 can be cut out from the top wall panel 10 by making cuts along the separation lines 18 that form the edges of each of the cuttable areas 19 after passing the object to be contained 15 through the object to be contained 17, as described later.

[0065] Furthermore, the cut-out area 19 includes at least one minimum unit section 16, and as described above, the minimum unit section 16 has one object insertion section 17, so the cut-out area 19 is a portion formed as an area having at least one object insertion section 17.

[0066] (First embodiment, six detachable regions) Figures 1 to 7 show the first embodiment. In the sheet material 3 of the packaging box 1 shown in Figure 1, six cuttable areas 19 are formed on the top wall panel 10, separated by the separation lines 18. Each cuttable area 19 is comprised of four minimum unit sections 16, and each cuttable area 19 is formed with four receiving body insertion sections 17.

[0067] The configurations within each of the six cuttable regions 19 are identical. To facilitate the diagrammatic explanation, reference numerals are used to indicate each part within only one of the cuttable regions 19, while reference numerals are omitted for the other cuttable regions 19. The same applies to the cuttable regions 19 of the sheet material 3 in other embodiments described later.

[0068] The following describes a case where four containments 15 are grouped together by passing each of the containments 15 through the containment insertion section 17 in a single cuttable area 19. While cutting at the position of the separation line 18 located around one of the cuttable areas 19 in the top wall panel 10, the cuttable area 19 is separated from the top wall panel 10 and pushed down.

[0069] Since the body insertion section 17 is located at the upper position of the body to be contained 15, the upper part of the body to be contained 15 is inserted into each of the body insertion sections 17 located in the cuttable area 19 as the cuttable area 19 descends. When the object to be contained 15 is inserted into the object insertion section 17, the individual tabs are pushed up by the object to be contained 15 viewed from below the top wall panel 10, and an opening is formed inside the object insertion section 17 through which the object to be contained 15 passes. This allows the object to be contained 15 to be inserted into the object insertion section 17.

[0070] Each raised tab experiences a resistive force attempting to restore its shape, causing each tab to engage with the inserted portion of the containment 15. Therefore, the detachable area 19 separated from the top wall panel 10 is attached to the four occupants 15, and these four occupants 15 are grouped together by the detachable area 19, making it possible to handle the four occupants 15 and one detachable area 19 as a single unit. Figure 4 shows the contents 15, which are removed from the box body 2 in sets of four, and the detachable area 19 attached to them and integrated with them.

[0071] In this way, in the cuttable area 19 which is partially pushed down and cut out from the top wall panel 10, multiple occupants 15 can be easily bundled together by inserting and locking each occupant 15 into the occupant insertion section 17, corresponding to the number of occupant insertion sections 17 in the cuttable area 19. Furthermore, when displaying a set of 15 contained objects bundled together, there is no need to prepare a separate packaging method (for example, a paper band) for the set of contained objects 15 in addition to the packaging box 1, thus reducing the amount of packaging material that is discarded.

[0072] (Finger hook forming part) Furthermore, each of the cut-out regions 19 is provided with a pair of finger-hook forming portions 20 in the center of the cut-out region 19, through which a person's finger (for example, a retail worker who displays the contained items 15 or a consumer of the contained items) can be inserted.

[0073] The finger-grip forming section 20 consists of a crease and an arc-shaped perforation extending to the end of the crease. By pressing down on the crescent-shaped small piece surrounded by the crease and the tear-off perforation, a finger-grip hole 21 is formed, allowing for finger gripping. Retail workers and consumers can then place their fingers through the finger-grip hole 21, enabling them to carry the contents 15 with the tear-off area 19 attached together.

[0074] (Information display section) Reference numeral 22 denotes the information display unit. This information display unit 22 is provided on the upper surface of the top wall panel 10 in each of the above-mentioned cut-out areas 19 (the surface that a person can see from above, whether the bundled contents 15 are inside the box body 2 or the bundled contents 15 have been removed from the box body 2).

[0075] The information display section 22 is the part that displays product information, ingredient information, manufacturing plant information, etc. Of course, the information provided in the information display section 22 is not limited to the examples mentioned above, and may also include product logos, catchphrases, etc., and is not limited to being composed of eye-catching information such as character illustrations or images.

[0076] Furthermore, although the illustrated example shows the information display unit 22 as a barcode, the format of the information display is not limited. Also, although one information display unit 22 is placed in the cuttable area 19 that holds together the four containment units 15, it is also possible to place an information display unit 22 near each of the containment unit insertion sections 17.

[0077] (Side wall panels on all four sides of the sheet material) The first side wall panel 11 of the sheet material 3 is superimposed on the first side surface 2b of the box body 2, and the bottom side of this first side wall panel 11, i.e., the lower end side, is attached to the front wall panel 5 of the first side surface 2b. The second side wall panel 12 is superimposed on the second side surface 2c of the box body 2, and the lower end side of this second side wall panel 12 is attached to the rear wall panel 6 of the second side surface 2c.

[0078] Furthermore, the third side wall panel 13 is superimposed on the third side surface 2d of the box body 2, covering the inner side wall flaps 7 and 8 of the third side surface 2d, and covering the upper end of the outer side wall flap 9 on the third side surface 2d, with the lower end of the third side wall panel 13 being attached to the outer surface of the outer side wall flap 9.

[0079] Similarly, the fourth side wall panel 14 is superimposed on the fourth side surface 2e of the box body 2, covering the inner side wall flaps 7 and 8 of the fourth side surface 2e, and covering the upper end of the outer side wall flap 9 on the fourth side surface 2e, with the lower end of the fourth side wall panel 14 attached to the outer surface of the outer side wall flap 9.

[0080] The lower ends of the first side wall panel 11, the second side wall panel 12, the third side wall panel 13, and the fourth side wall panel 14 are bonded to the box body 2 using adhesive. The area where adhesive is applied and bonded to the box body 2 is called the bonded area 23. The adhesive portion 23 itself may be configured such that adhesive is pre-applied to the first side wall panel 11, the second side wall panel 12, the third side wall panel 13, and the fourth side wall panel 14, and then protected by release paper, or the adhesive may be applied when attaching it to the box body 2.

[0081] (Means of separation) Furthermore, the first side wall panel 11, the second side wall panel 12, the third side wall panel 13, and the fourth side wall panel 14 are provided with a separation means 24 that separates each of the first side wall panel 11, the second side wall panel 12, the third side wall panel 13, and the fourth side wall panel 14 into the bottom and top sides of the packaging box, that is, separates them vertically. This separation means 24 is positioned towards the top of the packaging box from the location of each of the adhesive parts 23.

[0082] The separation means 24 is positioned in a strip shape along the longitudinal direction of each first side wall panel 11, second side wall panel 12, third side wall panel 13, and fourth side wall panel 14, and perforations are provided on the upper and lower edges of the separation means 24. Furthermore, as described above, the separation means 24 of this embodiment has perforations arranged in two rows, upper and lower, with a strip-like area between the perforations. Therefore, when separating the side wall panels, the strip-like portion between the perforations can be pulled along the perforations, allowing the first side wall panel 11, the second side wall panel 12, the third side wall panel 13, and the fourth side wall panel 14 to be easily separated vertically without the use of any tools.

[0083] Figure 5 shows that only the first side wall panel 11 is separated into the bottom side (lower end side) and the top side of the packaging box. However, at the position of the separation means 24, the other second side wall panel 12, third side wall panel 13, and fourth side wall panel 14 can also be separated into the bottom side and the top side, as described above. When the upper and lower parts are separated at the position of all the side wall panels, the bottom area of ​​each side wall panel is adhered to each wall of the packaging box 1, so that only the top wall panel 10 side of the sheet material 3 attached to the box body 2 can be quickly removed from the box body 2.

[0084] In the illustrated example, the top wall panel 10 side of the sheet material 3 is first removed from the packaging box 1, and then all six detachable regions 19 are separated from each other from the removed top wall panel 10, and each of the detachable regions 19 is attached from above the four containers 15. Since only the portion on the top wall panel 10 side that has been removed can be handled in this way, each cuttable area 19 can be smoothly attached to the housing 15.

[0085] As a result, for example, in a retail store, when selecting a display method in which the bundles of the contained items 15 are arranged one by one on a designated sales area (shelf), the sheet material 3 can be easily removed from the box body 2, and the bundles of contained items 15 can be displayed as a product using the cuttable area 19.

[0086] Of course, this is not limited to cases where four containers are grouped together; even in the form of a cut-out area 19 that groups together six containers 15 as described later, the sheet material 3 can be easily removed from the box body 2, each cut-out area 19 can be smoothly attached to the containers 15, and the work of displaying the products as a group using the cut-out areas 19 is also simple.

[0087] Furthermore, even in the sheet material 3 described later, which has one removable section 19 and one container insertion section 17, and combines one container 15 with one removable section 19, it can be easily removed from the box body 2, and the work of separating each removable section 19 and displaying the product in a form in which one removable section 19 is combined with one container 15 can be easily performed.

[0088] By simply cutting out one of the six cuttable areas 19 shown in Figures 1 and 3, a partial opening can be created in the sheet material 3 of the packaging box 1. In this way, by cutting out the cuttable areas 19 from the sheet material 3 of the packaging box 1, the contents 15 can be removed from the packaging box 1.

[0089] In packaging box 1, it is not necessary to use the entire cut-off area 19 to create a set of contents 15 (a group of contents). In other words, the contents 15 contained in the packaging box 1 can be individually removed from the partial opening on the top of the box created by cutting out the cut-out area 19. The packaging box 1 of this embodiment can appropriately accommodate various display configurations, such as displaying a set of contents 15 bundled together by the cut-out area 19, or displaying individual parts of the contents 15 on the sales floor.

[0090] (Handle) As described above, on the third side 2d and fourth side 2e of the box body 2, side wall outer flaps 9 connected to the bottom wall plate 4 are erected. The material of these side wall outer flaps 9 is corrugated cardboard, and it is a highly rigid surface material.

[0091] Therefore, in this embodiment, handles 25 are provided on the outer side flaps 9 on two opposing sides of the packaging box 1, so that when necessary, the packaging box 1 can be lifted by placing a hand on the handle 25.

[0092] Figure 6 shows the fourth side 2e of the packaging box 1, where the inner side flap 7 and inner side flap 8 are arranged side by side at the position of the fourth side 2e, and the outer side flap 9, which rises from the bottom of the box, is overlapped and glued to the outer side flap 9, with a height that extends from the midpoint between the inner side flap 7 and inner side flap 8 towards the top of the packaging box.

[0093] Furthermore, the handle means 25 is positioned at the center in the lateral direction of the outer side flap 9, and at a height close to the center of gravity of the packaging box 1 containing the contents 15.

[0094] As shown in Figure 6, the handle means 25 is a part that divides a folded-back piece 28 with a mountain-shaped fold line 26 and a roughly U-shaped perforation 27 that is continuous with the end of the fold line 26 and protrudes toward the bottom of the box, so that when desired the folded-back piece 28 can be folded toward the box body 2 side (i.e., toward the inside of the box body 2) at the position of the fold line 26 and then folded upwards.

[0095] The folded-over piece 28, surrounded by the fold lines 26 and perforations 27, is divided into left and right halves by a vertical slit connected to the top of the mountain-shaped fold lines 26. When folded, the two halves are folded diagonally upward in different directions, creating a handle hole that is difficult for the hand to move when it is placed on it.

[0096] The handle means 25 is not limited to the above example. Perforations may be made around the entire circumference of the portion that will become the handle hole so that a handle hole can be obtained when needed, and the handle hole may be formed by cutting along the perforations. Alternatively, the handle hole may be pre-opened as a through-hole.

[0097] Furthermore, although not shown in the figures, the inner side wall flaps 7 and 8 have a cutout shape in the portion corresponding to the handle means 25, so that the folded-back piece 28 can be folded in and fingertips can be inserted without any hindrance.

[0098] (Notch at the lower end of the side wall panel) Furthermore, as shown in Figure 6, the lower end of the fourth side wall panel 14 of the sheet material 3 overlaps and is attached to the upper end of the side wall outer flap 9 on which the handle means 25 is located. The fourth side wall panel 14 is provided with a notch 29 that covers the upper end of the side wall outer flap 9 but does not interfere with the handle means 25, that is, it exposes the handle means 25 to the outside.

[0099] (Arrangement of the lower end of the side wall panel and the outer side wall flap) In this way, the lower end of the fourth side wall panel 14 of the sheet material 3 is overlapped with the outer surface of the side wall outer flap 9 and attached to the side wall outer flap 9, so that there is no part below the fourth side wall panel 14 for placing one's hands other than the above-mentioned handle means 25. Therefore, when handling the packaging box 1, it is possible to prevent problems such as tearing the fourth side wall panel 14 by directly touching its lower edge.

[0100] Alternatively, as shown by the dashed line in Figure 7, the lower end of the fourth side wall panel 14 may be positioned to abut against the upper end of the outer side wall flap 9, and the lower end of this fourth side wall panel 14 may be attached to the inner side wall flaps 7 and 8. In this case as well, there will be no part below the fourth side wall panel 14 for placing hands on other than the handle means 25. When the abutting arrangement is adopted, the notch 29 is not provided.

[0101] The configuration of the handle means 25 and the arrangement in which the fourth side wall panel 14 overlaps with or abuts against the side wall outer flap 9 were explained using the fourth side 2e as an example, and the same configuration is used for the third side 2d.

[0102] (Second embodiment, four detachable regions) In the sheet material 3 of the packaging box 1 shown in Figures 1 to 7 as the first embodiment, the top wall panel 10 is divided into six cuttable areas 19 by separation lines 18. However, the present invention is not limited to dividing and forming six cuttable areas 19 within the top wall panel 10, nor is it limited to providing four contents insertion areas 17 within one cuttable area 19.

[0103] Figures 8 to 10 show a second embodiment, which is another example of the division of the cuttable region 19 that is divided within the top wall panel 10. Figures 8 to 10 illustrate a sheet material 3 in which four cuttable regions 19 are divided and formed within the top wall panel 10, a packaging box 1 using this sheet material 3, and examples of how the cuttable regions 19 are used.

[0104] In the second embodiment, each of the four cuttable regions 19 divided by the separation line 18 in the top wall panel 10 is provided with six insertion portions 17 for housing objects. In the packaging box 1, where the sheet material 3 is attached so that the body insertion portion 17 corresponds to the upper position of each of the bodies 15 contained, the cut portion 19 is pushed down, as in the example described above, and the cut portion is removed from the top wall panel 10 by cutting at the position of the separation line 18.

[0105] Furthermore, by passing the upper part of each of the six containment insertion sections 17 through them, the six containment sections 15 can be grouped together in a single detachable section 19, allowing them to be handled as a single unit.

[0106] As in the above embodiment, an information display unit 22 is provided on the upper surface of the cuttable area 19 that combines the six contained bodies 15. As in the above embodiment, this information display unit 22 can be configured to allow information to be confirmed visually or to be machine-read using a reading device. Furthermore, as in the above embodiment, it can be configured to represent information using character diagrams or pictures.

[0107] Furthermore, the first side wall panel 11, second side wall panel 12, third side wall panel 13, and stepped side wall panel 14 of the sheet material 3 are attached to the box body 2, the box body 2 is assembled from the bottom wall plate 4, front wall plate 5, rear wall plate 6, inner side wall flaps 7 and 8, and outer side wall flap 9, the handling means 25 is provided, and the overlapping and butt-joint arrangement of the third side wall panel 13 and outer side wall flap 9, and the overlapping and butt-joint arrangement of the stepped side wall panel 14 and outer side wall flap 9 are the same as in the above embodiment.

[0108] (Third embodiment, form of a cuttable region for each minimum unit section 16) Figures 11 to 13 show a third embodiment. In the third embodiment, each of the smallest unit sections 16 in the top wall panel 10 is made into a cut-out area 19. Each of these cut-out areas 19, which can be cut out from the top wall panel 10 by a separation line 18, is equipped with a single object insertion section 17.

[0109] The small, detachable area section 19, consisting of the smallest unit section 16, is also separated from the top wall panel 10 by cutting the separation line 18 by pushing down from the position that forms the lid of the packaging box 1, and the upper part of the container 15 is passed through the container insertion section 17.

[0110] In the third embodiment, an information display unit 22 is provided on the upper side of the cuttable area 19, and the information display unit 22 can be combined with one container 15. Except for the fact that the finger rest forming portion 20 is unnecessary, the other configurations in the third embodiment are the same as in the above embodiment.

[0111] In the first embodiment described above, an information display unit 22 is provided in a cut-out area 19 that has four body insertion sections 17, and the information display unit 22 is combined with four body insertion sections 15. However, it is also possible to place the information display unit 22 near the four body insertion sections 17 in the cut-out area 19, thereby creating a one-to-one correspondence between the information display unit 22 and the body insertion sections 15.

[0112] In the second embodiment described above, the one-to-one correspondence between the information display unit 22 and the contained object 15 can also be achieved by arranging the information display unit 22 near the six contained object insertion portions 17 provided in the cut-out area 19.

[0113] (Circumferential connection of side wall panels) Next, a modified example of the sheet material 3 will be described with reference to Figure 14. As shown in Figure 14, in the modified sheet material 3, each of the side ends of the first side wall panel 11 that are opposite each other in the width direction is provided with an engaging piece 30 for engaging with the third side wall panel 13 and the fourth side wall panel 14 that are adjacent to the first side wall panel 11 in the circumferential direction of the packaging box.

[0114] Similarly, each of the side ends of the second side wall panel 12 of the sheet material 3 that are opposite each other in the width direction is provided with an engaging piece 30 for engaging with the third side wall panel 13 and the fourth side wall panel 14 that are adjacent to the second side wall panel 12 in the circumferential direction of the packaging box.

[0115] Furthermore, the third side wall panel 13 and the fourth side wall panel 14 are provided with engagement holes 31 that engage with the engagement piece 30, and there are two engagement holes 31 at the end sides of the third side wall panel 13 and the fourth side wall panel 14, which are formed by cutting into the panel material.

[0116] According to the sheet material 3 shown as this modified example, the following configuration is presented. First, the lower ends of the third side wall panel 13 and the fourth side wall panel 14 are attached to the upper end of the outer side flap 9 of the box body 2, as described above. Furthermore, the first side wall panel 11 and the second side wall panel 12 are not glued to the front wall panel 5 and rear wall panel 6 of the box body 2, but are only overlapped, and the sheet material 3 is attached to the box body 2, which already contains the contents 15, in this state.

[0117] Next, the engaging pieces 30 provided on the first side wall panel 11 and the second side wall panel 12 are inserted into the engaging holes 31 between the third side wall panel 13 and the fourth side wall panel 14 and engaged.

[0118] As a result, the sheet material 3 can be attached to the box body 2 simply by attaching two of the three side walls, the third side wall panel 13 and the fourth side wall panel 14, to the outer side flap 9 of the box body 2. Therefore, compared to the method described above in which the four side wall panels—the first side wall panel 11, the second side wall panel 12, the third side wall panel 13, and the fourth side wall panel 14—are attached to the four sides of the box body, the amount of adhesive used can be reduced.

[0119] Embodiments of the present invention have been described in detail above. However, the foregoing description is intended to facilitate understanding of the present invention and is not intended to limit it. The present invention may include modifications and improvements that can be made without departing from its spirit. Furthermore, the present invention includes equivalents thereof.
