Description

[Technical field]

[0001] The present disclosure relates to aluminum foil packages. [Background technology]

[0002] In addition to its use in cooking, aluminum foil is also used as a craft material, taking advantage of its high degree of processing flexibility and its characteristics of being less susceptible to staining. However, when using roll-type packages of aluminum foil for creative work, it is time-consuming to unroll the aluminum foil from the roll and cut it.

[0003] In response to this, a single-piece package has been devised in which multiple sheets of aluminum foil are bundled together (see Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Jpn. Jpn. Published No. 60-37326 Summary of the Invention [Problem to be solved by the invention]

[0005] Aluminum foil is thin and easily deformed, so when pulling out the aluminum foil one sheet at a time in the single-sheet type described above, the aluminum foil can wrinkle or tear.

[0006] One aspect of the present disclosure aims to provide an aluminum foil package that allows the aluminum foil to be easily removed and prevents the occurrence of wrinkles and tears. [Means for solving the problem]

[0007] One aspect of the present disclosure is an aluminum foil package including a plurality of aluminum foil laminates each including a plurality of aluminum foils laminated together, and a case for housing the plurality of aluminum foil laminates. Each of the plurality of aluminum foil laminates has a retaining portion for retaining the plurality of aluminum foils in a bundled state.

[0008] According to this configuration, the aluminum foil can be removed from the case in units of aluminum foil stacks each including a plurality of aluminum foils bound together, making it easy to remove the aluminum foil and preventing the aluminum foil from being wrinkled or torn when removed.

[Figure 6] FIG. 6 is a schematic cross-sectional view showing an aluminum foil package in an embodiment different from those in FIGS. 1A and 1B. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, embodiments to which the present disclosure is applied will be described with reference to the drawings. [1. First embodiment] [1-1. Configuration] The aluminum foil package 1 shown in FIGS. 1A and 1B includes a plurality of aluminum foil laminates 2 and a case 3.

[0011] <Aluminum foil laminate> The aluminum foil laminate 2 is formed by stacking a plurality of aluminum foils in the thickness direction.

[0012] In this embodiment, the number of aluminum foils contained in the multiple aluminum foil laminates 2 is equal. That is, in one aluminum foil package 1, the number of aluminum foils constituting the aluminum foil laminate 2 is constant.

[0013] For example, in the aluminum foil package 1 in Fig. 1A, the number of aluminum foils included in each of the multiple aluminum foil stacks 2 is 5. In the aluminum foil package 1 in Fig. 1B, the number of aluminum foils included in each of the multiple aluminum foil stacks 2 is 20.

[0014] The thickness of one aluminum foil constituting the aluminum foil laminate 2 is, for example, 10 μm or less. The thickness of one aluminum foil laminate 2 (specifically, the thickness of the portion excluding the maintaining portion 22) is, for example, 30 μm or more. By achieving such a thickness relationship, the thin and easily processable aluminum foil can be easily removed from the case 3 without causing wrinkles or tears.

[0015] 2A, the aluminum foil stack 2 has a maintaining portion 22 that maintains a bundled state of a plurality of aluminum foils 21. The maintaining portion 22 is a means for bundling the plurality of aluminum foils 21.

[0016] 2A is an adhesive (i.e., glue) that bonds the ends of multiple aluminum foils 21 in the thickness direction. The adhesive is applied to the surfaces of the aluminum foils 21 so that the ends of the aluminum foils 21 can be fixed together, and bonds adjacent aluminum foils 21 together. This makes it easy to remove the aluminum foil stack 2 from the case 3 while preventing the aluminum foils 21 from coming apart.

[0017] The adhesive used as the maintaining portion 22 is preferably one that allows the two aluminum foils 21 to be separated after the aluminum foil laminate 2 is taken out of the case 3 (that is, one that does not completely solidify).

[0018] The retaining portion 22 may be a tape wound around the ends of the stacked aluminum foils. As shown in Fig. 2B, the retaining portion 22 may be a pressure-bonding portion that presses the ends of the stacked aluminum foils.

[0019] 1A and 1B, the multiple aluminum foil laminates 2 are housed in the case 3 such that the retaining portions 22 overlap each other in the thickness direction of the aluminum foil laminate 2. In other words, the multiple aluminum foil laminates 2 are housed in the case 3 in the same orientation.

[0020] <Case> The case 3 contains a plurality of aluminum foil laminates 2. The case 3 has an opening 31 through which the plurality of aluminum foil laminates 2 can be taken out in a direction perpendicular to the thickness direction (i.e., in the surface direction of the aluminum foil).

[0021] The case 3 may or may not have a lid for opening and closing the opening 31. That is, the case 3 may be a box type having a lid, or a sleeve type in which the opening 31 is open.

[0022] The multiple aluminum foil stacks 2 are stored in the case 3 so as to be pulled out from the opening 31 with the retaining portion 22 at the front. That is, the multiple aluminum foil stacks 2 are stored in the case 3 with the retaining portion 22 oriented toward the opening 31. Also, the multiple aluminum foil stacks 2 can be taken out of the case 3 one by one.

[0023] The case 3 has markings 30 indicating the number of aluminum foils (i.e., the number of sheets constituting a bundle) contained in the aluminum foil laminate 2. The markings 30 are arranged, for example, on a different surface from the opening 31 of the case 3.

[0024] [1-2. Effects] According to the embodiment described above in detail, the following effects can be obtained. (1a) The aluminum foil can be removed from the case 3 in units of aluminum foil stack 2, which is a bundle of aluminum foils. This makes it easy to remove the aluminum foil, and also prevents the aluminum foil from being wrinkled or torn when removed.

[0025] (1b) The case 3 has markings 30 indicating the number of pieces of aluminum foil contained in the aluminum foil laminate 2, making it easier for consumers to select an aluminum foil package 1.

[0026] [2. Second embodiment] [2-1. Configuration] The aluminum foil package 1A shown in Fig. 3A includes a plurality of aluminum foil laminates 2, a case 3, and a plurality of partitions 4. The aluminum foil laminate 2 and the case 3 are the same as those of the aluminum foil package 1 of the first embodiment.

[0027] <Partition> The partition portion 4 is a sheet-like member sandwiched between a plurality of aluminum foil laminates 2 in the thickness direction of the aluminum foil laminate 2.

[0028] The partition portion 4 overlaps the entire surface of the aluminum foil laminate 2. At least a part of the partition portion 4 protrudes to the outside of the aluminum foil laminate 2 when viewed from the thickness direction of the aluminum foil laminate 2. The partition portion 4 is housed inside the case 3 together with the aluminum foil laminate 2. At least a part of the partition portion 4 may protrude to the outside of the case 3 through an opening 31 of the case 3.

[0029] The partition 4 may be a sticker as shown in Fig. 3B. The partition 4 in Fig. 3B is attached to the surface of a corner of the aluminum foil laminate 2 that is close to the opening 31, and a part of the partition 4 protrudes outside the aluminum foil laminate 2.

[0030] It is not necessary that the partitions 4 are disposed between all adjacent aluminum foil stacks 2. For example, as shown in Fig. 4A, the partitions 4 may be disposed at positions that separate two aluminum foil stacks 2 from each other.

[0031] As shown in Fig. 4A and Fig. 4B, the aluminum foil package 1A may have a plurality of partitions 4 of different colors. This makes it easier to grasp the number of bundles (i.e., aluminum foil laminates 2). In the example of Fig. 4A, one white partition 4 is provided after four black partitions 4 in a row. In other words, the black partition 4 indicates a partition for a bundle of 2, and the white partition 4 indicates a partition for a bundle of 10. Although Fig. 4A and Fig. 4B show sticker-type partitions 4, the colors of the sheet-like partitions 4 can also be different.

[0032] [2-2. Effects] According to the embodiment described above in detail, the following effects can be obtained. (2a) The partition 4 makes it easy to take out any number of aluminum foil laminates 2. In addition, the remaining number of aluminum foil laminates 2 in the case 3 can be easily confirmed.

[0033] [3. Third embodiment] [3-1. Configuration] The aluminum foil package 1B shown in Fig. 5 includes a plurality of aluminum foil laminates 2, a case 3, a plurality of partitions 4, and a rod member 5. The aluminum foil laminate 2, the case 3, and the partitions 4 are the same as those of the aluminum foil package 1A of the second embodiment.

[0034] <Bar member> The rod member 5 penetrates through the ends of the plurality of aluminum foil laminates 2 and the plurality of partition portions 4 in the thickness direction.

[0035] Specifically, the rod member 5 is inserted through a hole provided in the retaining portion 22 of the aluminum foil laminate 2 (more specifically, a corner portion of the aluminum foil laminate 2) and a hole provided in the partition portion 4. The rod member 5 is housed in the case 3 together with the aluminum foil laminate 2 and the partition portion 4.

[0036] [3-2. Effects] According to the embodiment described above in detail, the following effects can be obtained. (3a) The aluminum foil laminate 2 can be removed from the case 3 while the partition 4 is kept overlapping the aluminum foil laminate 2 by the rod member 5.

[0037] [4. Fourth embodiment] [4-1. Configuration] An aluminum foil package 1C shown in Fig. 6 includes a plurality of aluminum foil laminates 2 and a case 3C. The aluminum foil laminate 2 is the same as the aluminum foil package 1 of the first embodiment.

[0038] <Case> The case 3C houses a plurality of aluminum foil laminates 2. The case 3C has a main body 32, an outlet 33, and a holding member .

[0039] The main body 32 is a rectangular box. The aluminum foil laminates 2 are stacked in the thickness direction inside the main body 32. The removal opening 33 is an opening provided across a part of the first wall 321 of the main body 32 that faces the surface of the aluminum foil laminate 2 and a side wall that is continuous with the first wall 321. The aluminum foil laminate 2 is pulled out from the removal opening 33 to the outside of the main body 32.

[0040] The holding member 34 is disposed inside the main body 32, and is a spacer for providing a step between the ends of the adjacent aluminum foil stacks 2. The holding member 34 has a step surface 341 that comes into contact with the side surfaces of the aluminum foil stacks 2.

[0041] The stepped surface 341 has a plurality of steps provided in a direction away from the first wall 321 where the removal opening 33 is provided, and approaching the second wall 322 of the main body 32. The second wall 322 is the wall opposite the removal opening 33, among the walls facing the side surface of the aluminum foil laminate 2 of the main body 32.

[0042] The multiple aluminum foil laminates 2 are arranged one for each step of the stepped surface 341. Specifically, among the side surfaces of the aluminum foil laminate 2, the side surface close to the second wall 322 is in contact with the stepped surface 341 in a direction perpendicular to the thickness direction of the aluminum foil laminate 2 (i.e., the surface direction). Therefore, the farther an aluminum foil laminate 2 is from the removal opening 33 in the thickness direction of the aluminum foil laminate 2, the smaller the distance from the second wall 322.

[0043] In this manner, the case 3C accommodates a plurality of aluminum foil laminates 2 so that a step is formed between the ends of adjacent aluminum foil laminates 2 in the thickness direction of the aluminum foil laminates 2.

[0044] The case 3C can be placed in a direction in which the holding members 34 support the aluminum foil stack 2 from below (i.e., the removal opening 33 faces upward). The steps between the multiple aluminum foil stacks 2 are maintained by the holding members 34.

[0045] [4-2. Effects] According to the embodiment described above in detail, the following effects can be obtained. (4a) By providing steps between multiple aluminum foil laminates 2, it becomes easy to take out the aluminum foil laminates 2 one by one.

[0046] 5. Other embodiments Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above-described embodiments and can take various forms.

[0047] (5a) In the aluminum foil package of the above embodiment, the number of aluminum foils contained in the multiple aluminum foil laminates does not necessarily have to be equal. For example, a five-sheet aluminum foil laminate and a twenty-sheet aluminum foil laminate may be housed in one case.

[0048] (5b) The function of one component in the above embodiments may be distributed among multiple components, or the functions of multiple components may be integrated into one component. In addition, a part of the configuration of the above embodiments may be omitted. In addition, at least a part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments. Note that all aspects included in the technical idea identified from the wording of the claims are embodiments of the present disclosure. [Explanation of symbols]
