Summary of the Invention

Problems to be Solved by the Invention

[0005] However, there is a problem that the conventional cooling device is not configured to be convenient for carrying or for cooling an affected part.

[0006] For example, in the case of the devices proposed in Patent Document 1 and Patent Document 2, when taking out the ice pack from the cold - storage container for use, it is not easy to grip the ice pack with fingers, so it cannot be suitably cooled while being applied to the affected part.

[0007] ​On the other hand, the device proposed in Patent Document 3 has a handle on the ice pack, making it easy to apply the ice pack to the affected area by grasping the handle with the fingers. However, when the ice pack is stored in a cooler container for carrying, the handle protrudes, which poses a problem as it makes the cooling device bulky when carried in a bag or the like.

[0008] Furthermore, conventional cooling systems have many issues that need to be addressed.

[0009] The present invention aims to provide a portable cooling device for the affected area that solves the problems described above. [Means for solving the problem]

[0010] Therefore, the means configured in this invention consists of a bottomed cylindrical insulated cooling container with an opening at the top, and an ice pack structure that is detachably inserted into the cooling container, wherein the cooling container is formed in a circular cross-section, and the ice pack structure consists of a stopper means and an ice pack means that is detachably suspended below the stopper means, wherein the ice pack means is configured to contain a cooling element including ice, and the stopper means integrally comprises a stopper portion and a cap portion, and the stopper portion is screwed into the opening of the cooling container. In addition, the opening is sealed, and the cap portion forms a disc with a peripheral wall having an peripheral surface substantially continuous with the peripheral surface of the cooling container, and is provided with a pair of pivots located in the diametrical direction of the disc and protruding from the peripheral surface, and is provided with an arch-shaped dam extending along substantially half the circumference of the peripheral surface between the two pivots, and both ends of the dam is pivotally supported by the pivots, and the dam is configured to be able to change its position between a stowed position along the peripheral surface of the disc and an upright position standing upright toward the top of the disc.

[0011] In an embodiment of the present invention, the cap portion of the stopper means forms a heat insulating chamber that opens downward inside the surrounding peripheral wall, and heat insulating material is filled into the heat insulating chamber. The stopper portion of the stopper means is fixed to the lower part of the peripheral wall of the cap portion and is provided with a partition wall portion that closes the opening of the heat insulating chamber and a stopper cylinder portion that extends downward from the partition wall portion, and the stopper cylinder portion is configured to be screwed in and out of the opening of the insulated container.

[0012] In a preferred embodiment, the ice pack means comprises a cylindrical attachment detachably inserted into the stopper portion of the stopper means, and an elastic, bottomed cylindrical ice pack container fixed to and suspended from the lower cylindrical portion of the attachment. The upper part of the ice pack container forms an opening wall, and the outer circumference of the opening wall is held by a retaining ring. The opening wall of the ice pack container is fixed in a compressed state via elasticity between the outer circumferential surface of the lower cylindrical portion of the attachment and the inner circumferential surface of the retaining ring. [Effects of the Invention]

[0013] According to this invention, the portable affected area cooling device 1 can be used to cool an affected area of ​​the human body by applying it, similar to a conventional ice pack, by storing a cooling element such as ice in the ice pack container 13 of the ice pack component 1B.

[0014] When carrying the portable wound cooling device 1, the ice pack component 1B is placed in the cooling container 1A, thereby keeping the ice pack container 13 in a cooled state. This allows the ice to remain frozen for a long period of time without easily melting.

[0015] The cap portion 5 of the plugging mechanism 2 is provided with a retaining arm 10. The retaining arm 10 is formed in an arch shape that extends along approximately half the circumference of the outer surface of the disc-shaped cap portion 5 of the plugging mechanism 2. Both ends of the retaining arm 10 are pivotally connected to a pivot 9 that protrudes in the diametrical direction of the disc. The retaining arm 10 is configured to be able to change its position between a retracted position P1 along the outer surface of the peripheral wall 5a of the disc and an upright position P2 standing above the disc.

[0016] Therefore, when the handle 10 is held by the user's fingers in the standing posture P2, the plug means 2 is suspended in a stable state disposed inside both ends of the handle 10.

[0017] Therefore, when the handle 10 is in the storage posture P1, it is arranged along the outer periphery of the cap portion 5 of the plug means 2, so that the portable affected part cooling device 1 can be in a compact state without bulging as a whole.

[0018] Particularly, when the portable affected part cooling device 1 in a state where the ice pack body 1B is housed in the cold storage container 1A is placed on a table or the like in a lying-down posture, no matter whether it is in the storage posture P1 or the standing posture P2, both ends of the handle 10 protrude from the outer peripheral surface of the cap portion 5. Therefore, there is an advantage that the portable affected part cooling device 1 formed in a substantially cylindrical shape as a whole does not roll and wander on the table surface.

Mode for Carrying Out the Invention

[0020] Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings.

[0021] As shown in FIGS. 1 to 4, the portable affected part cooling device 1 is composed of a heat-insulating cold storage container 1A having a bottomed cylindrical shape with an opening at the upper part, and an ice pack structure 1B that is detachably inserted into the cold storage container 1A.

[0022] The ice pack structure 1B is used for cooling by applying it to an affected part of the human body, similar to a conventional ice pack, by storing a cooling element such as ice (hereinafter simply referred to as "ice"). The cold storage container 1A has a heat-insulating structure with a double wall made of stainless steel having a circular cross-section, and holds a cold storage state by accommodating the ice pack structure 1B, and provides a portable affected part cooling device 1. Thereby, since the ice pack structure 1B is kept cold inside the cold storage container 1A during carrying, the ice can be maintained in a frozen state for a long time without easily melting, and if necessary, the ice pack structure 1B can be taken out from the cold storage container 1A and used.

[0023] The ice pack structure 1B includes a plug means 2 and an ice pack means 3 that is detachably suspended below the plug means 2, and is configured to store ice in the ice pack means 3.

[0024] The plug means 2 integrally includes a plug portion 4 and a cap portion 5, and the ice pack structure 1B is constituted by attaching the ice pack means 3 to the plug portion 4.

[0025] When the ice pack component 1B is placed in the insulated container 1A, with the ice pack means 3 inserted into the insulated container 1A, the stopper portion 4 is screwed into the opening of the insulated container 1A, sealing the insulated container 1A. For this purpose, the opening of the insulated container 1A is provided with a female screw 6, and the stopper portion 4 is provided with a male screw 7. When screwed in, the packing 8 provided on the stopper portion 4 makes tight contact with the opening edge of the insulated container 1A.

[0026] The cap portion 5 forms a disc with a peripheral wall 5a having a peripheral surface (i.e., a circumferential surface of approximately the same diameter) that is substantially continuous with the peripheral surface of the insulated container 1A, and is provided with a pair of pivots 9 located in the diametrical direction of the disc and protruding from the peripheral surface of the peripheral wall 5a, and an arch-shaped dam 10 is provided between the two pivots 9, 9 that extends along approximately half the circumference of the peripheral surface.

[0027] The dam 10 is pivotally supported at both ends by the pivot 9. As a result, the dam 10 is configured to be able to change its orientation between a retracted position P1, in which it is along the outer circumferential surface of the peripheral wall 5a of the disc-shaped cap portion 5, and an upright position P2, in which it is standing upright toward the top of the disc.

[0028] Therefore, when screwing the male thread 7 of the plug portion 4 into or out of the female thread 6 of the cooling container 1A, the ice pack component 1B can be easily rotated by gripping the handle 10 in an upright position P2. Also, when removing the ice pack component 1B from the cooling container 1A and applying it to the user's affected area, the handle 10 can be gripped in an upright position P2, making the work easier.

[0029] On the other hand, when carrying the ice pack component 1B while it is stored in the cooling container 1A, the entire unit becomes compact and less bulky by setting the handle 10 to the stored position P1, making it convenient to carry in a bag, for example.

[0030] Furthermore, when the portable affected part cooling device 1 with the ice pack structure 1B housed in the cold storage container 1A is placed horizontally on a table or the like, regardless of whether it is in the storage posture P1 or the standing posture P2, both ends of the dike handle 10 protrude from the disk-shaped peripheral wall 5a of the cap part 5. Therefore, there is an advantage that the cold storage container 1A and the cap part 5 do not roll and wander on the table surface.

[0031] As shown in FIG. 5, the cap part 5 of the plug means 2 forms a heat insulation chamber 5b that opens downward by an internal space surrounded by the peripheral wall 5a, and the heat insulation chamber 5b is filled with a heat insulating material 11.

[0032] At this time, the plug part 4 of the plug means 2 has a partition wall part 4a that closes the lower opening of the heat insulation chamber 5b by being fixed to the lower part of the peripheral wall of the cap part 5 by ultrasonic welding or the like, and a plug cylinder part 4b extends downward from the partition wall part 4a. In addition, the packing 8 is attached to the upper end part of the outer periphery of the plug cylinder part 4b.

[0033] The ice pack means 3 is composed of a cylindrical attachment 12 that is detachably inserted into the plug cylinder part 4b of the plug part 2 of the plug means 2 and a bottomed cylindrical ice pack container 13.

[0034] The attachment 12 integrally forms an upper cylindrical part 12b that extends above the flange 12a and a lower cylindrical part 12c that extends downward. On the other hand, the ice pack container 13 is formed in a bottomed cylindrical shape with an open upper part and is integrally molded by an elastic material such as silicon. An opening wall 14 that forms the upper opening is externally inserted into the lower cylindrical part 12c of the attachment 12 and fixed by a holding ring 15.

[0035] As shown in FIGS. 6 and 7, the inner diameter D1 of the opening wall 14 of the ice pack container 13 and the outer diameter D2 of the lower cylindrical part 12c of the attachment 12 are formed so that D1≤D2. However, as will be described later, in the range of D1<D2, it is necessary to be able to insert the lower cylindrical part 12c while compressing the opening wall 14 by elastic deformation, and the difference between D2 - D1 is small (for example, about 0.1 to 0.5 mm).

[0036] As shown in the figure, the opening wall 14 has a thickened portion 14a at the opening edge, with the thickness increasing towards the outer circumference, and a groove 14b is formed on the lower circumferential surface of the thickened portion 14a.

[0037] In contrast, the retaining ring 15 comprises an inner circumferential protrusion 15b that fits into the groove 14b, and a retaining wall 15a that embraces the outer circumference of the thickened portion 14a.

[0038] Since the entire ice pack container 13, including the opening wall 14, is made of an elastic material such as silicone, the opening wall 14 is elastically deformable inward, as shown by the dashed line in Figure 6. Through this deformation, the retaining ring 15 is fitted onto the outer circumference of the opening wall 14, as shown in Figure 7. At this time, the inner circumferential protrusion 15b is fitted into the recessed groove 14b, and the holding wall 15a holds the thickened portion 14a.

[0039] Therefore, when the lower cylindrical portion 12c of the attachment 12 is pressed into the opening wall 14 while the opening wall 14 is held by the retaining ring 15, the opening wall 14 is compressed and fixed between the outer circumferential surface of the lower cylindrical portion 12c and the inner circumferential surface of the retaining ring 15 via elasticity, thereby completing the ice pack means 3 in which the ice pack container 13 and the attachment 12 are integrally connected.

[0040] The ice pack means 3 is used as an ice pack after ice is inserted into the ice pack container 13 through the opening of the attachment 12 and then the lid is closed by attaching the stopper means 2.

[0041] In the illustrated embodiment, a female thread 16 is provided on the plug portion 4b of the plug portion 4 of the plugging means 2, and a male thread 17 is provided on the upper cylindrical portion 12a of the attachment 12, so that the plug portion 4b and the upper cylindrical portion 12a are detachably connected by screwing them together, but the means are not limited to screws.

[0042] In this case, it is preferable to provide a packing 18 on the lower side of the partition wall portion 4a of the plug portion 4, and by pressing the end of the upper cylindrical portion 12a against the packing 18, the ice pack means 3 can be sealed in a watertight manner.

[0043] Since the portable affected area cooling device 1 is configured as described above, by storing a cooling element such as ice in the ice pack container 13 of the ice pack component 1B, it can be used to cool the affected area of ​​the human body by applying it, just like a conventional ice pack.

[0044] The ice pack structure 1B is configured to have a detachable ice pack means 3 including an ice pack container 13 and a stopper means 2. Therefore, after storing ice in the ice pack container 13 with the stopper means 2 removed, the ice can be sealed by closing it with the stopper means 2.

[0045] Applying the ice pack to an affected area of ​​the body is easy because the stopper 10 of the plugging mechanism 2 can be grasped with the fingers while in an upright position P2.

[0046] Furthermore, when carrying it, the ice pack component 1B can be placed in the insulated container 1A, thereby keeping the ice pack container 13 in a cooled state, allowing the ice to remain frozen for a long period of time without melting. When carrying it, the handle 10 can be grasped with the fingers in an upright position P2.

[0047] Since the retaining arm 10 can be placed in the retracted position P1 when carrying the device, the entire portable wound cooling device 1 can be placed in a bag or the like in a compact, non-bulky state.

[0048] Incidentally, the retaining hand 10 is formed in an arch shape that extends along approximately half the circumference of the outer surface of the disc-shaped cap portion 5 of the plugging means 2, and both ends are pivotally connected to a pivot 9 that protrudes in the diametrical direction of the disc. Therefore, when the retaining hand 10 is held in an upright position P2, the plugging means 2 is suspended from the inside of both ends of the retaining hand 10, allowing the portable wound cooling device 1 to be carried in a stable suspended state.

[0049] Furthermore, when the portable wound cooling device 1, with the ice pack component 1B stored in the cooling container 1A, is placed on a table or the like in a horizontal position, both ends of the retaining handle 10 protrude from the outer surface of the cap portion 5, regardless of whether it is in the stored position P1 or the upright position P2. Therefore, the portable wound cooling device 1 will not roll around on the table surface. [Explanation of Symbols]
