Description

Technical Field

[0001] The present invention relates to upper and lower stage partition plates used when a plurality of flat individual packaging bags are vertically erected and stacked vertically to be externally packaged with a flexible packaging bag. The present invention also relates to a package using these partition plates.

Background Art

[0002] Conventionally, coffee drip bags, tea bags such as black tea or green tea, baked confectioneries such as senbei, and sanitary materials such as sanitary masks and menstrual pads are stored in individual packaging bags to have a flat shape, and then a plurality of them are stored in an outer box or an outer bag for sale. As a form of storing individual packaging bags in an outer box or an outer bag, generally, a plurality of individual packaging bags are often vertically erected (the second figure of Patent Document 1, Figure 10 of Patent Document 2, Figure 1 of Patent Document 3, etc. and Figure 3 of Patent Document 4). When stored in such a form, as described in each figure of Patent Documents 1 to 4, an individual packaging bag assembly composed of a plurality of individual packaging bags is stored in one layer, and the individual packaging bag assembly is not stored in two upper and lower layers or three upper and lower layers, etc.

[0003] When trying to store the individual packaging bag assembly in two upper and lower layers, since the individual packaging bags have a flat shape, there is a situation where the individual packaging bags in the upper individual packaging bag assembly fall into the lower individual packaging bag assembly during transportation. To prevent this, it is conceivable to insert a flat plate between the upper and lower layers. In this case, there is a situation where the individual packaging bags existing at the upper end in contact with the outer bag or the outer box fall to the lower layer. In particular, when the outer bag is a soft flexible packaging bag made of a synthetic resin film, since the soft packaging bag is easily deformed, there is a situation where the individual packaging bags existing at the ends in the upper individual packaging bag assembly fall along the soft packaging bag. In addition, when the individual packaging bag assembly is stored in two upper and lower layers or three layers, etc., there is also a risk that the articles stored in the lower individual packaging bags may bend or break due to the weight of the upper layer.

Patent Document 1

[0005] The object of the present invention is to provide an upper and lower partition plate that prevents the upper individual packaging bags from falling into the lower ones, even when a stack of individual packaging bags, consisting of multiple flat individual packaging bags placed vertically, is enclosed in a flexible packaging bag. [Means for solving the problem]

[0006] The present invention solves the above problem by giving the upper and lower partition plates a unique shape. Specifically, the present invention relates to an upper and lower partition plate for a flexible packaging bag in a packaging body in which a collection of individual packaging bags, each consisting of multiple flat individual packaging bags standing vertically, is stacked vertically and then enclosed in a flexible packaging bag, wherein the partition plate separates the upper and lower sections of the collection of individual packaging bags, and the partition plate has a central portion and left and right portions that are partially connected to the central portion via weakening lines, the unconnected portions of the left and right portions are tongue-shaped portions that bite into the central portion, the portions outside the tongue-shaped portions are the main body portions, and the tongue-shaped portions are separated from the central portion. The present invention also relates to a packaging body using this upper and lower partition plate.

[0007] The packaging according to the present invention consists of stacking multiple flat individual packaging bags 1 vertically to form individual packaging bag assemblies 2a and 2b, and then covering them with a flexible packaging bag 3. Specifically, the flexible packaging bag 3, made of synthetic resin film or the like, serves as the outer covering, with individual packaging bag assemblies 2a stored in the upper layer and individual packaging bag assemblies 2b stored in the lower layer. Examples of items to be stored in the flat individual packaging bags 1 include coffee drip bags, tea bags such as black tea or green tea, baked goods such as rice crackers, or sanitary materials such as sanitary masks and sanitary napkins. In particular, the present invention is preferably applied when packaging luxury goods such as coffee drip bags, which are prone to changes in flavor when compressed. This is because when the stacked packaging is compressed, the individual packaging bags in the upper layer are less likely to fall to the lower layer even without an upper and lower partition plate, thus reducing the need to apply the present invention.

[0008] A partition plate 4 is positioned between the upper and lower individual packaging bag assemblies 2a and 2b. The partition plate 4 is made of cardboard with a thickness of 0.3 to 1.0 mm, especially about 0.5 mm, but is not limited to this, and a relatively rigid material such as a synthetic resin sheet may also be used. Figure 2 is a plan view of the partition plate 4 before the packaging is manufactured. The partition plate 4 consists of a central part 5 (dark ink part in Figure 2), one of its left parts 6c (light ink part in Figure 2), and the other right part 6d (light ink part in Figure 2). The central part 5 and the left and right parts 6c and 6d are connected in some places via a weakening line 7. Perforations or creases can be used as the weakening line 7, but any material that is easy to fold may be used. The left and right portions 6c and 6d each consist of tongue-shaped portions 8c and 8d that penetrate the central portion 5, and left and right main body portions 9c and 9d outside the tongue-shaped portions 8c and 8d. The tongue-shaped portions 8c and 8d and the left and right main body portions 9c and 9d are integrated. The tongue-shaped portions 8c and 8d and the central portion 5 are separated. In Figure 2, the tongue-shaped portions 8c and 8d of the left and right portions 6c and 6d are shown to be line-symmetrical, but they may also be point-symmetrical or even symmetry-free.

[0009] Next, a method for manufacturing a package using this upper and lower partition plate 4 will be described. The upper and lower partition plate 4 shown in Figure 2 is folded along the weakening line 7 as the folding line, so that the main body parts 9c, 9d and the tongue parts 8c, 8d are perpendicular to the paper surface. The front view after folding is approximately H-shaped, as shown in Figure 3. Then, an assembly of individual packaging bags 2b, consisting of multiple individual packaging bags 1,1,1... is placed between the left main body part 9c and the right main body part 9d. Also, an assembly of individual packaging bags 2a, consisting of multiple individual packaging bags 1,1,1... is placed between the left tongue part 8c and the right tongue part 8d. Finally, the whole is placed in a flexible packaging bag 3 made of synthetic resin film or the like to obtain a package. In this invention, it is preferable that the length L from the weakening line 7 to the edges of the left and right parts is approximately the same as the height M when the individual packaging bag 1 is standing vertically. As a result, the left and right main body parts 9c and 9d act as walls, preventing the items stored in the individual packaging bags 1 in the lower individual packaging bag assembly 2b from bending or breaking inside the packaging due to the weight of the upper individual packaging bag assembly 2a.

[0010] Figures 1 to 3 illustrate the case where the individual packaging bags are stacked in two layers, but it is also possible to stack them in three or four layers, or more than two layers. In this case as well, by placing the upper and lower partition plates according to the present invention between each layer, it becomes more difficult for the individual packaging bags 1 in the upper layer to fall to the lower layer. Furthermore, in Figures 1 to 3, one upper and lower partition plate is placed between the upper and lower layers, but two or more upper partition plates may be used to divide each individual packaging bag assembly in the upper and lower layers into two or more sections. In this case, it becomes even more difficult for the individual packaging bags 1 in the upper layer to fall to the lower layer. [Effects of the Invention]

[0011] By using the upper and lower partition plates of the flexible packaging bag according to the present invention, a larger number of individual packaging bags can be stored than in conventional methods, and the individual packaging bags in the upper section can be prevented from falling to the lower section during transportation or sale of the packaging.
