Description

[Technical field]

[0001] This invention relates to an ice pack set for carrying ice packs in a cooled state. [Background technology]

[0002] In order to carry an ice bag in a cooled state, an ice bag set is known in which the ice bag is housed in an ice bag cooler made of a metal vacuum double bottle (see, for example, Patent Document 1). In such an ice bag set, the ice bag is attached to the ice bag cooler via a lid, and the ice bag can be attached and detached with a single touch. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7526998 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the ice bag set described above, the lid is held to the ice bag cooler only by the force of the packing sliding against the inner circumferential surface of the ice bag cooler, so when a user holds the lid and lifts the ice bag set, the lid may unintentionally come off the ice bag cooler, causing the ice bag cooler to fall.

[0005] To solve the above-mentioned problems, the present invention aims to provide an ice bag set in which the cooling device of the ice bag will not fall even when the lid of the ice bag is lifted, and which is easy to handle when using the ice bag. [Means for solving the problem]

[0006] The ice bag set of the present invention comprises an ice bag having a cylindrical ice bag body with a bottom for containing water or ice, a cooling device having an insulated structure that contains the ice bag, and a lid body that is screwed onto both the ice bag and the cooling device, and is characterized in that a handle formed in an approximately circular ring shape is attached to the lid body.

[0007] It is preferable that the lid body has a cylindrical portion that is accommodated within the cooling device and a flange portion that is held outside the cooling device, and that the handle is rotatable relative to the upper surface of the flange portion via one end of the handle.

[0008] The cylindrical portion preferably has a screw thread for screwing onto the ice pack and the cooling device, respectively.

[0009] It is preferable that the screw thread includes a female thread provided on the inner surface of the cylindrical portion and a male thread provided on the outer surface of the cylindrical portion, the ice pack has a connection portion provided at an opening of the ice pack body, the connection portion having a male thread on its outer surface that screws into the female thread of the cylindrical portion, and the cooling device has a female thread on its inner surface that screws into the male thread of the cylindrical portion.

[0010] The ice pack body is preferably made of silicone rubber and has a recess in the center of its outer circumferential surface. Effect of the Invention

[0011] According to the ice bag set of the present invention, the lid is firmly fixed to the cooling device, so even if you lift the ice bag set by holding the lid, the cooling device will not fall, and since it has a handle, the ice bag is easy to handle when using it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] An ice pack set according to an embodiment of the present invention will be described with reference to the drawings. As shown in Figures 1 and 2, ice pack set 1 includes ice pack 2 for storing water or ice water, cooling device 3 for storing ice pack 2, and lid 4 screwed to both ice pack 2 and cooling device 3.

[0014] The ice bag 2 has a cylindrical ice bag body 21 with a bottom, a connection part 22 provided at the opening of the ice bag body 21, a plug body 23 attached to the other end of the connection part 22 (the upper end in the illustrated example), and a gasket 24 attached to the plug body 23.

[0015] Ice bag body 21 is formed in a cylindrical shape with a bottom and an opening at the top for pouring water, and the center of its outer circumferential surface is recessed. Ice bag body 21 is made of soft rubber, fabric, or resin, preferably silicone rubber.

[0016] Connection part 22 is a cylindrical member made of a resin harder than ice bag body 21, and is welded to ice bag body 21. Connection part 22 has male threads 22a formed on the outer periphery on the side of upper end opening 22c. Male threads 22a screw into female threads 44a of lid 4, which will be described later. Connection part 22 also has protruding ridges 22b on which plug 23 is placed.

[0017] The plug 23 has a disk portion 23a formed in a substantially disk shape, a circular recess 23b provided on the upper surface of the disk portion 23a, and a cylindrical handle 23c provided in the center of the recess 23b. The lower peripheral edge of the disk portion 23a is placed on a protruding ridge portion 22b provided on the inner peripheral surface of the connecting portion 22, so that the plug 23 is detachably held at the upper end of the connecting portion 22.

[0018] The packing 24 has a disk portion 24a formed in a substantially disk shape, a circular convex portion 24b provided on the lower surface of the disk portion 24a, and a hole portion 24c provided so as to penetrate the center of the disk portion 24a and the convex portion 24b. The packing 24 is integrated with the plug body 23 by fitting the convex portion 24b into the concave portion 23b of the plug body 23. At this time, the handle 23c of the plug body 23 is configured to have a length that protrudes from the upper surface of the disk portion 24a through the hole portion 24c.

[0019] The cooling device 3 is formed in a cylindrical shape with a bottom, and has a heat-insulating structure made of, for example, a metal vacuum double-walled bottle. The cooling device 3 has a female screw 32 on the inner circumferential surface near the upper end opening 31. The female screw 32 is screwed into a male screw 44b of the lid 4 described later.

[0020] The lid body 4 has a flange portion 41 formed in an approximately circular plate shape and held outside the cooling device 3, a cylindrical portion 42 fixed to the underside of the flange portion 41, and a circular ring-shaped gasket 43 attached in close contact with the underside of the flange portion 41 and the outer peripheral surface of the cylindrical portion 42.

[0021] Cylindrical portion 42 is housed within ice cooling device 3 and has threads 44 for screwing together ice pack 2 and ice cooling device 3. Threads 44 include female threads 44a (see also FIG. 3(c)) provided on the inner circumferential surface of cylindrical portion 42 and male threads 44b provided on the outer circumferential surface of cylindrical portion 42. When female threads 44a completely screw together with male threads 22a of ice pack 2, flange 41 presses plug 23 against ridge portion 22b, and packing 24 is pressed against upper end opening 22c of connection portion 22, sealing the gap therebetween.

[0022] Then, with the lid 4 and ice bag 2 being integrated by the engagement of the female thread 44a and the male thread 22a, the male thread 44b of the lid 4 is engaged with the female thread 32 of the cooling device 3. As a result, the packing 43 is pressed against the upper edge 33 and the inner peripheral surface of the cooling device 3 by the flange 41, and the cooling device 3 is sealed with the ice bag 2 inserted.

[0023] 3(a) to 3(c), ice pack set 1 further includes handle 5 attached to lid 4. Handle 5 is formed in a generally D-shaped ring shape in a plan view and has arc portion 51 forming the curved portion of the D, and base portion 52 forming the straight portion of the D and thicker than arc portion 51.

[0024] The base 52 has a notch 53 cut out from the outside in a rectangular shape in a plan view, a pair of rotating shafts 54, 54 arranged on either side of the notch 53 so as to sandwich the notch 53, and a pair of through holes 55, 55 provided in each of the rotating shafts 54, 54. The through holes 55, 55 are provided so as to extend linearly from a side peripheral surface of one rotating shaft 54 ​​to a side peripheral surface of the other rotating shaft 54.

[0025] The cover 4 has a rotation support part 45 provided on the upper surface of the flange 41. The rotation support part 45 is formed to fit into the cutout part 53 of the handle 5, and has a through hole 46 provided to communicate with the through holes 55, 55. A shaft rod 6 is inserted into the through holes 55, 55, 46. This allows the handle 5 to rotate relative to the upper surface of the flange 41 with the shaft rod 6 as the rotation axis.

[0026] The cover 4 also has a handle holding part 47 that fits into the annular part of the handle 5 when the handle 5 is not rotating relative to the flange 41, i.e., when the handle 5 is parallel to the flange 41. The handle holding part 47 is formed in a platform shape so as to be flush with the upper surface of the handle 5 when it fits into the handle 5, and has a button-shaped raised part 48 (see FIG. 3(a)) on the side opposite the rotation support part 45. The raised part 48 fits into a groove part 56 provided on the inner peripheral surface of the handle 5 to lock the handle 5 when the handle 5 is parallel to the flange 41.

[0027] The connecting portion 22, the plug 23, the lid 4 and the handle 5 constructed as described above are made of a resin such as polypropylene. The packings 24 and 43 are made of an elastic material such as silicone rubber.

[0028] Next, a method of using ice bag set 1 will be described with reference to Fig. 1 again. First, in order to cool ice bag 2, lid 4 is removed from ice bag 2, and then handle 23c is held to remove plug 23 and packing 24 from connection part 22, and ice or ice water is poured into ice bag body 21 from upper end opening 22c of connection part 22. Then, plug 23 and packing 24 are reattached to connection part 22, and lid 4 is screwed onto connection part 22 to seal ice bag 2.

[0029] Alternatively, water may be poured into ice bag body 21 in the same manner as above, and ice bag 2 and lid 4 may be placed in a freezer to freeze the water in ice bag body 21. In this case, since ice bag body 21 has a depression in the center, it is possible to prevent ice bag body 21 from becoming unable to fit into cooling device 3 even if the volume of ice bag body 21 increases due to the freezing and expansion of water.

[0030] As shown in Fig. 4(a), when ice bag 2 cooled as described above is not in use, ice bag 2 is stored in cooling device 3 and lid 4 is screwed onto cooling device 3. This keeps ice bag 2 cool in cooling device 3, which has a thermal insulation structure. In the illustrated example, handle 5 is restricted from inadvertently rotating relative to lid 4 by fitting raised portion 48 of handle holding portion 47 into groove 56.

[0031] 4(b), by applying force to disengage groove 56 from raised portion 48 and rotating handle 5 relative to lid 4, it becomes possible to carry ice pack set 1 by hooking fingers in hole 51 of handle 5. Even in this case, since lid 4 is screwed to ice cooling device 3, there is no need to worry about ice cooling device 3 falling off lid 4.

[0032] When the ice pack 2 is removed by unscrewing the ice pack 3 from the lid 4, the ice pack 2 is exposed to the outside as shown in FIG. 5(a). At this time, the ice pack 2 is not removed from the lid 4 because it is screwed to the lid 4. The removed ice pack 2 is used for icing or cooling, and is stored back in the ice pack 3 after use. This prevents unnecessary temperature rise of the ice pack 2, and makes it possible to maintain the ice pack 2 at a low temperature for a long period of time. Also, as shown in FIG. 5(b), the ice pack 2 can be used with the handle 5 upright. This allows the user to insert his or her finger into the circular portion of the handle 5 and use the handle 5 as a handle to freely move the ice pack 21, making it easier to handle the ice pack 2 when using it.

[0033] As described above, according to ice bag set 1, lid body 4 is firmly fixed to ice bag 2 and ice cooling device 3 by being screwed onto them, so that ice bag 2 and / or ice cooling device 3 will not fall even if ice bag set 1 is lifted by holding lid body 4. Also, lid body 4 has handle 5, making it convenient to carry ice bag set 1. Furthermore, handle 5 is rotatable and can be stored substantially integrally with lid body 4 when not in use, so handle 5 does not get in the way and has excellent design.

[0034] Next, a modified example of the above embodiment will be described. For example, as shown in Fig. 6(a) and (b), a rectangular frame-shaped part 49 is further provided on the outside of the pivot support part 45 of the cover 4. A flat string can be passed through the frame-shaped part 49, or a hook attached to a bag or the like can be engaged with the frame-shaped part 49, making it convenient to carry the ice pack set 1.

[0035] The ice bag set according to the present invention is not limited to the above embodiment and can be modified in various ways. In the above embodiment, the inner and outer circumferential surfaces of the cylindrical portion 42 of the lid 4 are provided with threads for screwing with the ice bag and the cooling device, but as long as the lid is configured to screw with both the ice bag and the cooling device, the configuration is not limited to the above. For example, the cylindrical portion of the lid may have a two-stage structure with a large diameter at the top and a small diameter at the bottom, and a male screw provided on the outer circumferential surface of the large diameter portion may be screwed with a female screw provided on the inner circumferential surface of the cooling device, and a male screw provided on the outer circumferential surface of the small diameter portion may be screwed with a female screw provided on the inner circumferential surface of the connection portion of the ice bag. In this way, the opening diameter of the connection portion of the ice bag can be made large. The ice bag is intended to be frozen in a freezer after being filled with water, but if the opening diameter of the connection portion of the ice bag is large, it is easy to pour ice water into the ice bag, which is convenient when there is no time to freeze the ice bag.
