Abstract
Description
[Technical Field]
[0001] The present disclosure relates to packets and heel sap sheets. [Background technology]
[0002] Conventionally, there are packets in which sap powder is sandwiched between two sheets. The packet is attached to the center of an adhesive sheet, and the two sheets are attached together to the arch of the foot as a sap sheet, for example, when sleeping. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Mito 3084674 Summary of the Invention [Problem to be solved by the invention]
[0004] In recent years, it has become clear that applying the sachet to the heel rather than the arch of the foot is also effective.
[0005] However, currently available sachets on the market are not designed to be attached to the heel, and because the heel has a three-dimensional curved shape, the corners of the sap powder-containing portion of the sachet do not make good contact with the heel, which can result in insufficient efficacy.
[0006] For this reason, there is a demand for packets and heel sap sheets that can be easily attached to the heel. [Means for solving the problem]
[0007] According to a first aspect of the present disclosure, there is provided a packet comprising sap powder and two rectangular sheets, the two rectangular sheets having a sealing portion that is sealed along the entire edge of the two rectangular sheets, the sap powder being contained in a sap powder containing portion that is surrounded by the two rectangular sheets and the sealing portion, and two adjacent corners of the four corners of the rectangular sheets having notches.
[0008] The objects, features, and advantages of the present disclosure will become more apparent from the following description of the embodiments taken in conjunction with the accompanying drawings. [Brief explanation of the drawings]

[Figure 7B] FIG. 1 is a diagram showing an example of use of a heel sap sheet according to the prior art. DETAILED DESCRIPTION OF THE INVENTION
[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings, in which corresponding components are designated by common reference numerals throughout the drawings.
[0011] FIG. 1 is a plan view of a packet according to a first embodiment, and FIG. 2 is a cross-sectional view taken along line AA in FIG. 1. The packet 10a shown in these drawings is primarily composed of two rectangular sheets 11 and 12. For example, sheet 11 is a water-permeable nonwoven fabric, and sheet 12 is non-breathable rayon paper. These sheets 11 and 12 are overlapped with each other, and the entire edges of these sheets 11 and 12 are sealed as a sealed portion 20. As can be seen from FIG. 2, the space surrounded by sheets 11 and 12 and sealed portion 20 contains sap powder P. In other words, this space functions as a sap powder containing portion 30. The structure of packet 10a is generally similar to the structures of packets 10b and 10c, which will be described later.
[0012] Figure 5 is a plan view of a heel sap sheet provided with a packet according to the present disclosure. Figure 5 shows an adhesive sheet 50 having an adhesive surface coated with an adhesive. As shown, the packet 10a is placed approximately in the center of the adhesive surface of the adhesive sheet 50. The packet 10 is then attached together with the adhesive sheet 50 to the sole of the foot, for example, the arch. For this purpose, the packet 10 has dimensions suitable for the sole of a human foot.
[0013] As mentioned above, the sachet is mainly composed of two sheets, and the edges of the sheets are sealed. Due to the existence of the sealed parts, the corners of the sap powder containing part of the sachet do not make good contact with the three-dimensionally curved heel part.
[0014] In this regard, adjacent corners of the four corners of packet 10a shown in Figure 1 are formed with notches 41, 42. Notches 41, 42 may be formed, for example, in the shape of a quadrant or a triangle. Note that notches 41, 42 are formed in the area of sealing portion 20 and do not reach sap powder containing portion 30.
[0015] When cutouts 41, 42 are formed in this manner, the distance from the corners of sap powder containing portion 30 corresponding to cutouts 41, 42 to the adhesive surface of adhesive sheet 50 is shorter than before. This makes it possible to make the corners of sap powder containing portion 30 of packet 10a contact well with the heel portion, particularly the rear heel portion.
[0016] Figure 3 is a plan view of a packet according to the second embodiment. Notches 41 to 44 are formed at all corners of packet 10b shown in Figure 3. In this case, the distance from each of the four corners of sap powder containing portion 30 to the adhesive surface of adhesive sheet 50 is shorter than before. Therefore, it is possible to make the corners of sap powder containing portion 30 of packet 10b contact the heel portion well without considering the orientation of packet 10b.
[0017] In FIG. 1, the corners of the sap powder containing portion 30 are formed at approximately right angles, and therefore the shape of the corners of the sap powder containing portion 30 differs from the shape of the notches 41 and 42. In contrast, in FIG. 4, which is a plan view of a packet 10c according to the third embodiment, the corners of the sap powder containing portion 30 are formed in a quadrant shape. Alternatively, the corners of the sap powder containing portion 30 may be formed in a triangular shape. In other words, the corners of the sap powder containing portion 30 have a shape corresponding to the notch 41. In such a case, the width of the sealing portion 20 near the notches 41 and 42 is not extremely narrow. Therefore, even when the notches 41 and 42 are formed, it is possible to sufficiently maintain the strength of the sealing portion 20 near the notches 41 and 42. Figure 6 is a plan view of a packet according to the fourth embodiment. A pair of adjacent corners of the packet 10d shown in Figure 6 are formed with notches 43, 44 similar to those described above. In one embodiment, the notches 43, 44 are quadrants with a radius of 5 mm. Similarly to the above, the corners of the sap powder containing portion 30 corresponding to the notches 43, 44 have the same shape as the notches 43, 44. Furthermore, notches 41 and 42 are formed in a pair of adjacent corners opposite the notches 43 and 44. The dimensions of the notches 41 and 42 are larger than the dimensions of the notches 43 and 44. In one embodiment, the notches 41 and 42 are quadrants with a radius of 30 mm. The corners of the sap powder containing portion 30 corresponding to the notches 41 and 42 have the same shape as the notches 41 and 42. 6, the linear sealing portion 20 does not have to be present between the notches 41 and 42. In other words, the notches 41 and 42 may be smoothly connected, and the notches 41 and 42 may integrally form the curved portion 40. In this case, the curved portion 40 can be brought into better contact with the heel portion. Figure 7A shows an example of the use of a heel sap sheet according to the present disclosure, in which an adhesive sheet 51 containing a packet 10' consisting of a rectangular sealing portion 20' and a rectangular sap powder containing portion 30' of the prior art is attached to the area between the toes and the arch of a person's foot. 7A, an adhesive sheet 50 including the aforementioned sachet 10d is attached to the heel of a person's foot. As can be seen from the figure, the adhesive sheet 50 is attached so that the curved portion 40 of the sachet 10d roughly corresponds to the contour of the heel. Therefore, it can be seen that sufficient efficacy can be obtained by using the adhesive sheet 50 including the sachet 10d of the present disclosure. 7B is a diagram showing an example of the use of a conventional heel sap sheet. In FIG. 7B, the aforementioned adhesive sheet 51 is attached to the arch of a person's foot. Although not shown in the drawing, when adhesive sheet 51 is attached to the heel of a person's foot, rectangular sealing portion 20' of adhesive sheet 51 does not fit the outer shape of the heel, and as a result, it can be seen that the conventional adhesive sheet 51 does not provide sufficient efficacy.
[0018] In this way, the present disclosure can provide packets and heel sap sheets that can be easily attached to the heel area.
[0019] The following additional notes are provided regarding the above embodiments and modifications. (Appendix 1) Sap powder and two rectangular sheets; The two rectangular sheets have a sealing portion that is sealed along the entire edges of the two rectangular sheets; The sap powder is contained in a sap powder containing portion surrounded by the two rectangular sheets and the sealing portion, A packet, wherein two adjacent corners of the four corners of the rectangular sheet have notches.
