DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, a packaging method for the multi-connected cooking material pack of the present invention will be described. First, the cooking material pack used in the present invention can be formed by attaching two opposing films and has a bag portion.

[0014] As the film, a material having barrier properties can be used, for example, a resin film or the like can be mentioned. Examples of the resin film specifically include hydrocarbon-based films such as polyethylene film, polypropylene film, polybutene film, polybutadiene film, and polyisoprene film; halogenated hydrocarbon-based films such as polyvinylidene chloride film and polyvinyl chloride film; and ester-based films such as polyethylene terephthalate film and polybutylene terephthalate film.

[0015] Among these, in view of price and the fact that no harmful components are generated after incineration, hydrocarbon-based films are more preferable, and polyethylene film and polypropylene film are even more preferable.

[0016] One kind or two or more kinds of the films can be used. Also, it is preferable to use a laminate film as the film.

[0017] As a method of attaching the two films, there is no particular limitation, and examples thereof include a method of attaching with an adhesive, a method of attaching by heat melting, and the like. Among them, from the viewpoint of preserving the flavor of the contents, a method of attaching by heat melting is preferable. Examples of the method of attaching by heat melting include a method of heating the films with a heated metal press, a method of heating the films with an electric current, a method of heating the films with high frequency, and the like.

[0018] The cooking material pack includes a bag portion. FIG. 1 is a schematic perspective view for explaining the single pack 100. FIG. 2 is a schematic perspective view for explaining a set of three cooking material packs 200 formed based on the same connection direction of the set of three cooking material packs. For example, as illustrated in FIG. 1, in the single pack 100, one bag portion 3 is provided surrounded by an attachment portion 1 formed by attaching two films. For example, in the triple pack 200 in which one side of three single packs is shared, as illustrated in FIG. 2, three bag portions 3 are provided. In the triple pack 200 having three bag portions 3, a cutting line 5 can be provided at the attachment portion 1 at the boundary between the bag portions 3. Similarly, in a pack in which the sides of three or more single packs 100 are shared, the bag portion 3 is provided according to the number of single packs 100, and a cutting line 5 can be provided at the attachment portion 1 at the boundary between the bag portions 3 (not shown). By providing this cutting line 5, each part can be separated from the triple pack 200 along the cutting line 5. Examples of the cutting line 5 include a perforation. By providing the bag portion 3, the cooking material packs 100 and 200 can store cooking materials 7 such as shredded ingredients.

[0019] The shape of the cooking material pack 100 is substantially rectangular. The single pack 100 of the cooking ingredient pack has a long side length in the range of 10 to 14 cm and a short side length in the range of 7 to 11 cm, and it is more preferable if the long side length is in the range of 11 to 13 cm and the short side length is in the range of 8 to 10 cm. For example, if the cooking ingredient pack is a triple pack 200 in which the short sides of the single packs 100 are shared in the same direction, the long side length is in the range of 20 to 28 cm and the short side length is in the range of 7 to 11 cm, and it is more preferable if the long side length is in the range of 22 to 26 cm and the short side length is in the range of 8 to 10 cm. Similarly, when the cooking ingredient pack is a pack in which the sides of two or more single packs are shared, the length of the long side and the length of the short side of the cooking ingredient pack are determined according to the number of single packs 100, the lengths of their long sides and short sides, and the way of connection. The width of the sticking part of the cooking ingredient packs 100 and 200 is preferably in the range of 0.5 to 1.5 cm, and more preferably in the range of 0.5 to 1 cm.

[0020] The cooking ingredient packs used in the present invention are two or more cooking ingredient packs connected in the same direction in a set unit, and two or more cooking ingredient packs connected in the same direction in a set unit by folding back the cooking ingredient packs are stacked and used. It is preferable to use two or more cooking ingredient packs connected in the same direction in a set unit of three or more, and two or more cooking ingredient packs connected in the same direction in a set unit of three or more by folding back the cooking ingredient packs are stacked and used. A specific example of the cooking ingredient pack connected in the same direction in a set unit of three or more is as illustrated in FIG. 2.

[0021] FIG. 3 is a schematic diagram for explaining a cooking ingredient pack 300 in which the cooking ingredient packs are folded back and connected in the same direction in a set unit of three or more. In the case of FIG. 3, a cooking ingredient pack 300 is formed in which the cooking ingredient packs are folded back and connected in the same direction in a set unit of three or more.

[0022] Each cooking ingredient pack includes the cooking ingredient 7 stored in the bag portion 3. Examples of such cooking ingredients 7 include seasonings such as salt, sugar, pepper, sodium glutamate, dashi stock, dried small fish, dried shrimp, fish meal, tempura scraps, and shaved bonito flakes; seaweeds such as wakame seaweed, green laver, and green nori; and dried vegetables such as dried shredded daikon radish, etc. Examples of the shaved bonito flakes include, specifically, katsuobushi, magurobushi, miyabushi, scombermorus niphonius flakes, seriola dumerili flakes, and engraulis japonicus flakes, etc. The shape of the cooking ingredient is not particularly limited, and for example, it can be appropriately determined according to the purpose, such as powder form, flake form, fiber form, etc. Since the content elutes in a short time, the shape of the shaved bonito flakes is preferably thin flakes. As the cooking ingredient, shaved bonito flakes, dried small fish, dashi stock, etc. are preferred, and katsuobushi is even more preferred.

[0023] One or more kinds of the cooking ingredients 7 can be used.

[0024] The amount of the cooking ingredient 7 used in the present invention for each bag portion 3 is preferably in the range of 0.5 to 5 g, and more preferably in the range of 1 to 3 g.

[0025] When storing the cooking ingredient 7 in the bag portion 3, it is preferable to replace the air inside the bag with an inert gas in order to improve the storage stability of the seasoning material. Examples of such inert gases include nitrogen, helium, carbon dioxide, etc. One or more kinds of inert gases can be used.

[0026] After the cooking ingredient 7 is stored in the bag portions 3 of the respective cooking ingredient packs 100, 200, 300, the respective cooking ingredient packs 100, 200, 300 are sealed. While the four sides of each cooking ingredient pack 100, 200, 300 are adhered, since the cooking ingredient 7 is stored in the bag portion 3, the three-dimensional shape of the cooking ingredient pack has a planar adhered portion, while the bag portion forms a gentle curved surface.

[0027] There is no particular limitation on the method of stacking a plurality of cooking material packs 100, 200, 300. At the upstream side of the packaging device, the cooking material packs can be stacked in a plurality by a known method such as using a stacking device. According to the stacking device, for example, after the arm of the stacking device grabs the cooking material pack, it can be placed on the belt conveyor of the packaging device so as to be stacked vertically.

[0028] The number of layers of the cooking material packs to be stacked is preferably 2 to 12 layers, and more preferably 2 to 10 layers.

[0029] Next, examples of the present invention will be described with reference to the drawings, but the present invention is not limited to these examples at all.

Examples

[0030] FIG. 4 is a schematic perspective view for explaining a multi-connected cooking material pack 400 having a six-stage structure, in which 18 cooking material packs 400 are connected and folded in units of three. FIG. 5 is a schematic cross-sectional view showing a vertical cross-section in the connecting direction with respect to the same connecting direction of the cooking material packs 400 in units of three for 18 multi-connected cooking material packs 400 folded in units of three. First, 18 cooking material packs connected in the same direction are folded in units of three. These 18 numbers are preferably multiples of 3, more preferably any of 6, 9, 12, 15, 18, 21, 24, and even more preferably any of 15, 18, 21.

[0031] As illustrated in FIG. 5, a support 10 is installed at the lowermost part of 18 multi-connected cooking material packs 400 folded in units of three. In order for this support 10 to support 18 multi-connected cooking material packs 400 folded in units of three, 18 multi-connected cooking material packs 400 folded in units of three can maintain a certain shape as a whole, and can be packaged with a film 20 for 18 multi-connected cooking material packs 400 folded in units of three.

[0032] Next, 18 multi-connected cooking material packs 400 folded in units of three with a film are packaged. The 18 multi-connected cooking material packs 400 folded in units of three with the film 20 are wound with the film, and the overlapping portions 22, 24 of the films 20 are adhered. When adhering the overlapping portions 22, 24 of the films 20, if the adhesion between the film 20 and the multi-connected cooking material pack 400 is too strong, the multi-connected cooking material pack 400 will be deformed, which will hinder the in-store display of the multi-connected cooking material pack 400. On the other hand, if the adhesion between the film 20 and the multi-connected cooking material pack 400 is too weak, the multi-connected cooking material pack 400 will fall off from the film 20. From the viewpoints of the degree of deformation of the multi-connected cooking material pack 400 and the difficulty of falling off, the appropriate adhesion portions of the overlapping portions 22, 24 of the films 20 can be appropriately determined.

[0033] The film 20 used for the packaging of the present invention can be appropriately selected and used from the same materials as the resin film described above. In addition, as a method of adhering the overlapping portions 22, 24 of the films 20, for example, a method of adhering with an adhesive, a method of heating and fusing the film, etc. can be mentioned.

[0034] As shown in FIG. 5, based on the same connection direction of the cooking material packs 400 in a set of three units, the center line of the vertical cross-section in the connection direction passes through the support tool. Here, the same connection direction of the cooking material packs 400 in a set of three units refers to the direction along the dashed line A-A shown in FIG. 2. Also, the center line of the vertical cross-section in the connection direction shown in FIG. 5 refers to the direction along the dashed line B-B shown in FIG. 5. In addition, the center line of the vertical cross-section in the connection direction refers to a line passing through the central portion of the left and right lengths excluding the film 20 of the cooking material packs 400 in a set of three units in FIG. 5. The same applies to the following cases.

[0035] In the case of FIG. 5, the film 20 is superposed and adhered at a position outside the lowermost point in the lower direction of the support 10 and in contact with the support 10. Next, after adhering the overlapping portions 22 and 24 of the films 20 to each other, the support 10 is pulled out to obtain a multi-connected cooking material pack 400.

[0036] The size of the single pack of the cooking material pack used in Example 1 was 90 mm in length and 100 mm in width. Regarding the 18 multi-connected cooking material packs 400 folded in three-unit units shown in FIG. 4, experiments were conducted by changing the length of the film 20 in the same connection direction of the cooking material packs in a set of three. The results are shown in Table 1.

[0037]

Table 1

[0038] When the length of the film was changed in the same connection direction of the cooking material packs in a set of three, when it was 90 mm or less, the multi-connected cooking material pack 400 sagged and did not reach a practical product. Here, "sagging" means that the multi-connected cooking material pack 400 cannot maintain a certain shape, and when lifted, the overall shape changes. When this length was set to 100 mm or more, it was found that the sagging of the multi-connected cooking material pack 400 could be prevented and it could be provided as a practical product.

[0039] The length of the film 20 is less than the length of the cooking material packs in a set of three or more, covering the connecting portions other than both ends of the cooking material packs in a set of three or more, based on the same connection direction of the cooking material packs in a set of three or more. Here, "less than the length of the cooking material packs in a set of three or more" means that when a plane horizontal to the vertical cross-section direction is brought close to the cooking material packs in a set of three or more, based on the vertical cross-section direction in the same connection direction of the cooking material packs in a set of three or more, the plane horizontal to the vertical cross-section direction contacts the cooking material packs in a set of three or more earlier than the film 20. The same applies to the following cases. Even when the multi-connected cooking material pack 400 is lifted in this case, it maintains a certain shape. The length of the film 20 exceeds the connecting part 5 other than both ends of the set of three cooking material packs 400 and is less than the length of the set of three cooking material packs 400, based on the same connecting direction of the set of three cooking material packs 400. From the results in Table 1, when the length of the film is 100 mm or more with respect to the vertical 90 mm of the single pack of the cooking material pack, it is 100÷90 = 0.111. It was found that if the ratio of the length of the film with respect to the vertical 90 mm of the single pack of the cooking material pack is 111% or more, sagging of the multi-connected cooking material pack can be prevented and a practical product can be obtained. The relationship in Table 1 is the same for the following Examples 2 and 3 as well.

Example

[0040] Example 2 is the case of Example 1, but the shape of the support tool used is different. Hereinafter, the description will focus on the points different from the case of Example 1. Except for the points different from Example 1, it is the same as the case of Example 1. FIG. 6 is a schematic plan view for explaining the shape of the support tool used in each example. The support tool 10 used in Example 1 has the shape shown in FIG. 6(a). On the other hand, the support tool 12 used in Example 2 has the shape shown in FIG. 6(b), but it may have a ladder shape like the support tool 14 shown in FIG. 6(c).

[0041] Similar to the case of Example 1, in Example 2, 18 cooking material packs 500 are connected, folded back in units of three, and a multi-connected cooking material pack 500 with a six-stage configuration is used. The final shape is the same as that of Example 1.

[0042] FIG. 7 is a schematic cross-sectional view showing a vertical cross-section in the connecting direction, with respect to the same connecting direction of the cooking material packs 500 in units of three, for 18 multi-connected cooking material packs 500 folded back in units of three. As illustrated in Fig. 7, a support tool 12 is installed at the bottom of 18 multi-connected cooking material packs 500 folded in units of three. In order for this support tool 12 to support 18 multi-connected cooking material packs folded in units of three, the 18 multi-connected cooking material packs folded in units of three can maintain a certain shape as a whole, and the 18 multi-connected cooking material packs 500 folded in units of three can be packaged with the film 20. However, in the case of Example 2, based on the same connection direction of the three cooking material packs 500 in a group, there is a part where the center line of the vertical cross-section in the connection direction does not pass through the support tool 12, or it does not pass through the support tool 12.

[0043] Here, the part where the center line of the vertical cross-section in the connection direction does not pass through the support tool 12 means that, as shown in Fig. 6(c), it is in the shape of a ladder or the like, and the support tool can partially select the unconnected part among the inserted multi-connected cooking material packs. In this case, avoiding the connected parts among the inserted multi-connected cooking material packs 500, the overlapping parts 22, 24 of the films 20 are adhered.

[0044] Also, the center line of the vertical cross-section in the connection direction not passing through the support tool means that, as shown in Fig. 6(b), there is no connected part of the support tool 12 among the inserted multi-connected cooking material packs 500. Using the support tools 12, 14, etc. illustrated in Fig. 6 as appropriate, the overlapping parts 22, 24 of the films 20 are adhered in at least one of the continuous and intermittent forms.

[0045] In the case of Example 2, since the support tool 12 does not pass through the adhered part of the films 20, when pulling out the support tool 12 from the multi-connected cooking material packs 500, there is no worry of damaging the adhered part of the films 20, which is preferable.

Example

[0046] Example 3 is the same as Example 1 except that the bonding positions of the films are different. Hereinafter, the description will focus on the differences from Example 1. Except for the differences from Example 1, the other aspects are the same as in Example 1.

[0047] FIG. 8 is a schematic cross-sectional view showing a vertical cross-section in the direction perpendicular to the connection direction, with respect to 18 multi-connected cooking material packs 600 folded in units of three, based on the same connection direction of the cooking material packs 600 in a set of three. Similar to Example 1, in the case of Example 3, with respect to the same connection direction of the cooking material packs in a set of three, the center line of the vertical cross-section in the connection direction passes through the support tool. However, different from Example 1, the overlapping portions 22, 24 of the films 20 are overlapped and bonded at positions not in contact with the support tool 10, based on the vertical direction of the vertical cross-section in FIG. 8.

[0048] In the case of Example 3, since the support tool 10 does not come into contact with the overlapping portions 22, 24 of the films 20, there is no concern of damaging the overlapping portions 22, 24 of the films 20 when pulling out the support tool 10 from the multi-connected cooking material pack 600, which is preferable.

Industrial Applicability

[0049] According to the packaging method of the multi-connected cooking material pack of the present invention, since the multi-connected cooking material pack can be provided by a simple method, it can contribute widely particularly to the over-the-counter sales of multi-connected cooking material packs in the food industry.
