Embodiments for Carrying Out the Invention

[0018] A preferred embodiment of the ice pack bottle according to the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of the ice pack bottle. FIG. 2 is a side view of the ice pack bottle. FIG. 3 is a central longitudinal sectional view of the ice pack bottle. FIG. 4 is a central longitudinal sectional view of the main part. FIG. 5 is an exploded perspective view showing the component configuration of the ice pack bottle.

[0019] The ice pack bottle includes a cold storage device 1 formed in a bottomed cylindrical shape, and a lid portion 2 detachably attached to the opening of the cold storage device 1. The cold storage device 1 is formed in a bottomed cylindrical shape and is made of a metal such as stainless steel. The lid portion 2 has a handle portion 20 located at the upper part, and a lid body 21 with a male screw portion integrally connected. The two are connected so that they cannot be separated by methods such as press-fitting.

[0020] A handle 200 is formed on the handle portion 20, which can be held by fingers and has portability. A handle body 201 is integrally formed at the lower part of the handle 200. The handle body 201 has a cylindrical appearance and has an outer diameter the same size as, or approximately the same size as, the cold storage device 1.

[0021] The handle portion 20 and the lid body 21 can be formed of an appropriate resin. As shown in FIG. 4, a ring-shaped packing 22 is interposed between the handle portion 20 and the lid body 21. This ensures the watertightness between the handle portion 20 and the lid body 21.

[0022] The cold storage device 1 has a vacuum double structure in which an outer container member 10 and an inner container member 11 are joined. The outer container member 10 and the inner container member 11 are made of a metal such as stainless steel. By evacuating the space formed between the outer container member 10 and the inner container member 11, it has cold storage performance. The vacuum double structure is a well-known structure. A recess 100 for evacuation is provided on the bottom surface of the outer container member 10. As shown in FIG. 4, the upper end portion 1a of the cold storage device 1 is narrowed. A female screw portion is formed on the inner wall surface of this upper end portion 1a.

[0023] The lid body 21 is formed in a cylindrical shape, and a male screw portion 210 is formed on the outer surface of the cylinder. This male screw portion 210 can be screwed with the female screw portion formed on the upper end portion 1a of the cold storage device 1. Thereby, the lid portion 2 is detachably attached to the cold storage device 1. A ring-shaped packing 23 is fitted into the ring-shaped recess formed at the upper part of the male screw portion 210. This ensures the watertightness between the cold storage device 1 and the lid portion 2.

[0024] A female threaded portion 211 is formed on the inner wall surface of the lid body 21. A ring-shaped projection 212 is formed on the upper inner wall surface 213 of the lid body 21, facing downwards. The hollow member 4 is attached to this ring-shaped projection 212.

[0025] The hollow member 4 (an example of a shrinkable member) is formed from a flexible material such as silicone. However, as the flexible material, a shrinkable material such as a sponge (one that does not easily absorb water and has air pockets) may be used. The hollow member 4 includes a mounting portion 40 that is attached to the lid body 21, a large-diameter portion 41 formed below the mounting portion 40, and a small-diameter portion 42 formed below the large-diameter portion 41. The large-diameter portion 41 and the small-diameter portion 42 are formed in a cylindrical shape, and the lower end portion 45 of the small-diameter portion 42 is formed in a hemispherical shape.

[0026] The hollow member 4 is detachably attached to the lid body 21 by press-fitting the inner wall portion of the mounting portion 40 into the ring-shaped protrusion 212. Although it is press-fitted, the hollow member 40 is flexible and easily deformable, allowing for detachable attachment. The outer circumference 44 of the mounting portion 40 is also formed in a ring shape, with a ring-shaped recess 43 formed on its inner diameter side. Since the outer circumference 44 is attached while being pressed against the upper end surface 311, watertightness can be ensured so that water inside the ice pack body 30 does not leak to the outside.

[0027] The ice pack section 3 comprises an ice pack body 30, an ice pack support 31, an ice pack support ring 32, and a ring plate 33. The ice pack body 30 is formed in a bottomed cylindrical shape, with a flange 300 integrally formed on the upper part. Therefore, the outer diameter of the flange 300 is larger than the outer diameter of the ice pack body 30. The ice pack body 30 is made of metal, preferably an aluminum alloy (hereinafter referred to as "aluminum alloy"). However, metals other than aluminum (for example, stainless steel, etc.) may also be used. The ice pack body 30 can be manufactured, for example, by compression molding. Deep drawing may also be used as another manufacturing method. Aluminum alloy is a suitable material for these manufacturing methods.

[0028] The ice pack support 31 is formed in a cylindrical shape and has an inner wall surface 310 and an upper end surface 311. The upper end surface 311 abuts against the back surface of the mounting portion 40 of the hollow member 4, so as to maintain the mounting state of the hollow member 40. A male threaded portion 312 is formed on the outer wall surface of the ice pack support 31, which screws into the female threaded portion 211 of the lid body 21. In this way, the ice pack portion 3 can be detachably attached to the lid body 21.

[0029] A ring-shaped projection 316 is formed at the lower part of the ice pack support 31, and the lower surface of this projection 316 functions as a pressing portion 313. This pressing portion 313 allows the ice pack body 30 to be held stably within the ice pack portion 3. In addition, the lower side of the projection 316 functions as an engaging projection 314.

[0030] The ice pack support ring 32 has the function of supporting the ice pack body 30. The ice pack support ring 32 is integrally formed with an upper ring body 321 and a lower ring body 320. The upper ring body 320 has a larger diameter than the lower ring body 321. The upper part of the ice pack body 30 is inserted between the inner wall surface of the lower ring body 321 and the lower outer wall surface 315 of the ice pack support 31. The flange 300 of the ice pack body 30 is attached by being sandwiched between the upper end surface of the lower ring body 320 and the pressing surface 313 of the ice pack support 31. A thin pressing ring plate 33 is interposed between the flange 300 and the pressing surface 313. This pressing ring plate 33 is made of an elastic material such as silicone, so that it is compressed and can hold the ice pack body 30 in a stable state without rattling (without gaps). Furthermore, watertightness can be ensured so that water inside the ice pack container 30 does not leak out.

[0031] An engaging projection 322 is formed at the upper end of the upper ring body 321 of the ice pack support ring 32. As shown in Figure 4, the engaging projection 322 and the engaging projection 314 engage with each other, thereby securing the ice pack support ring 32 to the ice pack support 31 and preventing it from falling off, thus holding the ice pack body 30 in a stable state.

[0032] To assemble the ice pack section 3, insert the pressing ring plate 33 from the lower side of the ice pack support 31 and bring it into contact with the pressing surface 313, and then bring the flange 300 of the ice pack body 30 into contact with the back side of the pressing ring plate 33. In this state, insert the ice pack support ring 32 from the lower side of the ice pack body 30. The assembly of the ice pack section 3 is completed when the engaging projection 322 of the ice pack support ring 32 overcomes the engaging projection 314 of the ice pack support 31.

[0033] <How to use> The method of using the ice pack bottle according to this invention will now be explained. From the state shown in Figure 1, remove the lid 2 from the cooling device 1. By rotating the lid 2, the screw-fitted state between the cooling device 1 and the lid body 21 of the lid 2 is released. When the lid 2 is removed, the ice pack 3 is also removed integrally. Next, remove the ice pack 3 from the lid 2. By rotating the lid 2, the screw-fitted state between the lid body 21 of the lid 2 and the ice pack support 31 of the ice pack 3 is released. When the two are separated, the hollow member 4 is fitted into the ring-shaped protrusion 212 of the lid 2, so the hollow member 4 is attached to the side of the lid 2.

[0034] Next, water is placed inside the ice pack body 30. With the lid 2 in this state, it is screwed onto the ice pack body 3. At this time, the hollow member 4 is inserted into the ice pack body 30. No water is placed inside the hollow member 4 S2. Finally, the ice pack body 3, lid 2, and hollow member 4 are screwed onto the cooling device 1 as a single unit. This is then placed in a freezer to freeze the water in the ice pack body 30.

[0035] When water freezes and turns into ice, its volume increases. Consequently, internal pressure is applied to the ice pack body 30, which is made of aluminum alloy, causing cracks or deformation on the walls of the ice pack body 30. Therefore, by providing a flexible hollow member 4, the pressure is released into the hollow member 4, preventing damage and deformation of the ice pack body 30.

[0036] When using it as an ice pack, remove the lid 2 from the cooling device 1 and apply the ice pack body 30 to the neck or other areas to transfer the coldness to the skin. In particular, because the ice pack body is made of aluminum alloy (metal), it can deliver a shocking amount of coldness to the skin. This effect is achieved by using aluminum alloy (metal), which has better thermal conductivity than silicone.

[0037] The ice pack body 30 is manufactured by deep drawing. This is preferable to other manufacturing methods (e.g., casting) in terms of manufacturing cost. With this manufacturing method, it is desirable that the overall thickness be a constant desired value, but if there is variation in thickness, cracks may occur in the thinner areas and cause damage. The ice pack body 30 has the shape of a container, but variations in thickness tend to occur towards the bottom. This is due to misalignment of the mold during manufacturing, etc.

[0038] Therefore, as shown in Figure 7, the mold is manufactured so that a linear protrusion 301 is formed on the inner surface of the bottom. This makes it less likely for the mold to shift position. The shape of the protrusion is not limited to Figure 7, and various shapes can be used. The shape shown in Figure 7 is the shape of a grain of rice, but other shapes may be used. The arrangement, size, height, etc. of the protrusion can be set as appropriate. For the same reasons as above, it is preferable to also form a recess 302 on the outer surface of the bottom of the ice pack body 30, as shown in Figure 3. The size and shape of the recess can also be set as appropriate.

[0039] Figure 6 is a cross-sectional view showing the shape of the hollow member 4. The height H1 and outer diameter D2 of the small diameter section 42, the height H2 and outer diameter D1 of the large diameter section 41, and the height H3 of the mounting section 40 are shown. The dimensions and ratios of heights H1 and H2, and the size and ratios of outer diameters D1 and D2 can be appropriately set considering the shape of the ice pack body 30, the volume of water to be contained, etc. The same applies to height H3.

[0040] The shape of the hollow member 4 is not limited to the shape shown in Figure 6. It may be an inverted frustoconical shape instead of a stepped shape. Even when a step is formed, in this embodiment there is only one step, between the large diameter portion 41 and the small diameter portion 42, but it may also be a shape in which steps are formed in multiple places.

[0041] <Another Embodiment> The components that make up the ice pack bottle are formed from a number of cylindrical members, but are not limited to this. For example, some or all of the components may be formed in a non-cylindrical shape (e.g., ellipse, square, polygon, etc.).

[0042] The hollow member 4 is formed from a flexible material such as silicone. Since the hollow member also has the property of contracting under pressure, it is considered a contractible member. For a contractible member, the interior does not necessarily have to be hollow. Furthermore, even if it is a hollow member, the volume of the hollow portion can be set as appropriate.
