Summary of the Invention
Problems to be Solved by the Invention
[0006] Bottle-type ice packs offer excellent insulation and portability, allowing them to provide long-lasting cooling even when outdoors or on the go. However, further improvements in functionality, convenience, structural simplification, and ease of maintenance are desirable for such bottle-type ice packs.
[0007] The present invention aims to provide an ice pack bottle that is highly functional and convenient, has a simple structure, and is easy to maintain. [Means for solving the problem]
[0008] One aspect of the present invention is an ice pack bottle comprising: a bottomed container body having a main body opening; an ice pack portion having an ice pack opening and housed inside the container body; a lid connected to the container body, which closes the main body opening and to which the ice pack portion is detachably attached, which also closes the ice pack opening; and a sealing portion attached to the lid, which integrally seals the space between the lid and the main body opening, and the space between the lid and the ice pack opening.
[0009] With this configuration, the sealing portion seals both the gap between the lid and the main body opening, and the gap between the lid and the ice pack opening, with a single component.
[0010] In the ice pack bottle described above, the lid should be provided so that it can be screwed onto the container body regardless of whether the ice pack is attached or not. This allows the lid to be screwed onto the opening of the main body even when the ice pack is not attached.
[0011] In the ice pack bottle described above, the lid has a projection that extends downward from the underside of the lid and is positioned inside the ice pack opening, and the sealing part may be attached to the outside of the projection on the underside of the lid. As a result, both the space between the lid and the body opening, and the space between the lid and the ice pack opening are sealed by a single component, and the projection of the lid is positioned inside the container body and inside the ice pack section.
[0012] In the ice pack bottle described above, the ice pack section comprises an ice pack container and a connecting portion that connects the ice pack container to the lid. The connecting portion may be configured to be screwed into a protruding portion. This connecting portion connects the ice pack container to the lid by screwing it in.
[0013] In the ice pack bottle described above, the sealing portion may have a removal tab, and when the sealing portion is attached to the lid, the removal tab may be housed in a recess provided on the outer circumference of the protruding portion. This allows the sealing portion attached to the lid to be easily removed by pinching and pulling the removal tab.
[0014] In the above-described ice pack bottle, the ice pack container and the connecting part may be integrally formed from a metal material. This results in the ice pack portion, including the ice pack container and the connecting part, having an integrated structure made of metal material.
[0015] In the above-described ice pack bottle, the ice pack container and the connecting part may be made of resin material and connected to each other by adhesive. This constitutes an ice pack portion made of resin material.
[0016] In the above-described ice pack bottle, the ice pack container may be made of cloth material, and the ice pack container and the connecting part may be connected by an annular member. This allows the cloth ice pack container and the connecting part to be connected by an annular member, and enables the cloth ice pack container to be attached to the lid. [Effects of the Invention]
[0017] According to the present invention, it is possible to provide an ice pack bottle that is highly functional and convenient, has a simple structure, and is easy to maintain. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention
[0019] Hereinafter, embodiments of the present invention will be described based on the drawings. In the following description, the same members are denoted by the same reference numerals, and the description of the members once described will be omitted as appropriate.
[0020] (Ice pack bottle: First embodiment) Figure 1 is a perspective view illustrating an ice pack bottle according to the first embodiment. Figure 2 is a cross-sectional view illustrating an ice pack bottle according to the first embodiment. Figure 3 is an enlarged cross-sectional view illustrating the attachment of the lid. The ice pack bottle 1A according to the first embodiment comprises a container body 10, an ice pack section 20, a lid 30, and a sealing section 40. The ice pack bottle 1A is configured to be easily carried by housing the ice pack section 20 in the container body 10.
[0021] The container body 10 is provided in the shape of a bottomed cylinder having a main body opening 10h. The container body 10 has a double-walled structure (for example, a vacuum-insulated structure) made of stainless steel. In this embodiment, the side of the container body 10 with the main body opening 10h is referred to as "upper," and the bottom side of the container body 11 is referred to as "lower."
[0022] The ice pack section 20 is provided so as to be housed inside the container body 10 through the main body opening 10h of the container body 10. The ice pack section 20 has an ice pack opening 20h, and ice can be housed inside the ice pack container 21 through the ice pack opening 20h. The ice pack container 21 may be filled with water, or water may be placed inside the ice pack container 21 and frozen. Alternatively, a cooling agent may be placed inside instead of ice. In the first embodiment, the ice pack container 21 is made of silicone resin and is in the shape of a bottle.
[0023] The lid 30 is screwed onto the container body 10, closing the opening 10h of the main body. The outer circumference of the upper part of the container body 10 is provided with male threads 10a, and the lid 30 is provided with female threads 30b. The engagement of these male threads 10a and female threads 30b allows the lid 30 to be detachably connected to the upper part of the container body 10. In addition, the ice pack section 20 is detachably attached to the lid 30. That is, the lid 30 is used as a component that closes both the opening 10h of the main body and the opening 20h of the ice pack.
[0024] The ice pack section 20 is provided with a connecting section 22 that connects the ice pack container 21 to the lid 30. The lid 30 is provided with a projection 31 that extends downward from the back surface of the lid 30. The outer circumference of the projection 31 is provided with a male screw 31a that engages with a female screw 22b provided on the connecting section 22. Therefore, the ice pack section 20 is attached to the lid 30 by screwing the connecting section 22 into the projection 31. By attaching the ice pack section 20 to the lid 30, the projection 31 is positioned inside the ice pack opening 20h.
[0025] The sealing portion 40 is attached to the lid 30 and integrally seals the space between the lid 30 and the main body opening 10h, and between the lid 30 and the ice pack opening 20h. The sealing portion 40 is made of, for example, silicone rubber. The sealing portion 40 is attached to the back surface (lower surface) of the lid 30 and seals the space between the upper end of the ice pack portion 20 (the upper end of the connecting portion 22 in this embodiment) and the lid 30 (part A in Figure 3) when the ice pack portion 20 is attached to the lid 30. The sealing portion 40 also seals the space between the upper end of the container body 10 and the lid 30 (part B in Figure 3) when the lid 30 is screwed onto the container body 10. The sealing portion 40 is provided to seal parts A and B integrally (with one part).
[0026] In the ice pack bottle 1A according to this embodiment, since the sealing portion 40, which is a single component, seals portion A, which is between the lid 30 and the main body opening 10h, and portion B, which is between the lid 30 and the ice pack opening 20h, there is no need to construct the sealing portion 40 from multiple parts.
[0027] (Ice bag part) Figure 4 is a perspective view illustrating the state after the ice pack has been removed. Figure 5 is a perspective view illustrating the ice pack section. When the lid 30 is removed from the container body 10, the ice pack portion 20 is removed from the container body 10 along with the lid 30. That is, since the ice pack portion 20 is screwed onto the lid 30 by the connecting portion 22, even if the lid 30 is removed from the container body 10, the ice pack portion 20 does not detach from the lid 30 and is removed from the container body 10 together with the lid 30. As a result, when using it as an ice pack, the ice pack portion 20 can be removed from the container body 10 by removing the lid 30, and the ice pack container 21 can be applied to the affected area to cool it while the lid 30 is still attached.
[0028] The ice pack opening 20h in the ice pack section 20 is formed by an annular connecting section 22. The diameter of the ice pack opening 20h should be large enough to easily accommodate ice made in a household refrigerator (for example, 30mm to 35mm or larger).
[0029] It is preferable that an annular member 23 of the ice pack container 21 be provided between the ice pack container 21 and the connecting part 22. The annular member 23 is provided so as to surround the upper side of the ice pack container 21 (slightly below the lower end of the lid 30) in the circumferential direction. It is preferable that the surface of the annular member 23 has irregularities. This makes it easy to attach and detach the ice pack portion 20 to the lid 30 by screwing it in while holding the annular member 23 by hand.
[0030] The connecting portion 22 is made of, for example, polypropylene to ensure the strength of the screw connection with the protruding portion 31, and the annular member 23 is similarly made of, for example, polypropylene. On the other hand, the ice pack container 21 is made of a relatively flexible material, such as silicone resin, for holding ice or freezing water. The annular member 23 is also used as an intermediate member to connect the connecting portion 22 and the ice pack container 21. For example, the ice pack container 21 and the annular member 23 made of different materials are connected by fitting, and the annular member 23 and the connecting portion 22 made of the same material are connected by ultrasonic welding. This ensures that the ice pack container 21 and the connecting portion 22 made of different materials are reliably connected.
[0031] Furthermore, when connecting the ice pack container 21 and the annular member 23 made of different materials, it is preferable that the connection be made by fitting together the outer circumference of the ice pack container 21 and the inner circumference of the annular member 23 with interlocking grooves and protrusions that extend vertically to each other. In addition, it is preferable that the connecting part 22 be attached so as to cover the alignment position of the ice pack container 21 and the annular member 23. This enhances the reliable connection between the ice pack container 21, the annular member 23, and the connecting part 22, as well as the waterproofing at the joint.
[0032] Furthermore, it is preferable that the lid 30 be provided with a handle 32. When the lid 30 is attached to the container body 10, the handle 32 makes it easier to carry the ice pack bottle 1A. Also, when attaching or removing the lid 30 from the container body 10, the handle 32 makes it easier to rotate the lid 30.
[0033] (Lid) Figure 6 is a cross-sectional view illustrating the connection between the container body and the lid. In the ice pack bottle 1A according to this embodiment, the lid 30 can be screwed onto the container body 10 regardless of whether the ice pack portion 20 is attached to the lid 30. Figure 6 shows the state in which the ice pack portion 20 is not attached to the lid 30. Even when the ice pack portion 20 is not attached to the lid 30, the female thread 30b of the lid 30 can be screwed onto the male thread 10a of the container body 10. When the lid 30 is screwed onto the container body 10, the sealing portion 40 attached to the lid 30 is sandwiched between the upper end of the container body 10 and the back surface of the lid 30, thereby sealing the space between them. In the configuration in which the lid 30 is used without attaching the ice pack portion 20, the container body 11 can be filled with a beverage and the lid 30 can be tightened to make it usable as a beverage container.
[0034] Figure 7 is a cross-sectional view illustrating the connection between the ice pack and the lid. To attach the ice pack section 20 to the lid 30, the female thread 22b provided on the connection section 22 of the ice pack section 20 is screwed into the male thread 31a provided on the protruding section 31 of the lid 30. By attaching the ice pack section 20 to the lid 30, the protruding section 31 is positioned inside the ice pack opening 20h.
[0035] Here, the protrusion 31 is connected to the back surface of the lid 30, for example, by ultrasonic welding. The protrusion 31 is hollow, and by placing insulating material (for example, polystyrene foam) inside the protrusion 31, the cooling (heat retention) properties can be improved. In other words, the protrusion 31 functions as a component for connecting the ice pack 20 and the lid 30, and also functions as a part that is positioned inside the ice pack opening 20h to improve the cooling (heat retention) properties of the ice pack 20.
[0036] Furthermore, as shown in Figure 6, if the ice pack portion 20 is not attached to the lid 30, and the container body 10 is used as a beverage container by placing a beverage inside, attaching the lid 30 to the container body 10 will cause the cooling (heating) function of the protruding portion 31 to act on the beverage contained in the container body 11.
[0037] (Sealing part) Figure 8 is a perspective view illustrating a sealing portion attached to the lid. Figure 9 is an exploded perspective view of the lid and the sealing portion. The sealing portion 40 is attached to the back surface of the lid 30 by fitting around the outside of the protrusion 31. The sealing portion 40 is provided in a disc shape with a hole in the center when viewed in the vertical direction and is fitted onto the back surface of the lid 30. That is, the central hole 40h of the sealing portion 40 is inserted through the protrusion 31, and the sealing portion 40 is firmly fitted onto the back surface of the lid 30 by its elastic force. When the lid 30 is screwed onto the container body 10, the disc portion 41 of the sealing portion 40 comes into contact with the upper end of the container body 10 and the upper end of the ice pack portion 20, respectively. As a result, the sealing portion 40 as a single component can seal the space between the lid 30 and the main body opening 10h, and the space between the lid 30 and the ice pack opening 20h.
[0038] The sealing portion 40 may have a removal knob portion 42. Since the sealing portion 40 is fitted onto the back surface of the lid 30, it can be easily removed from the lid 30 by pinching and pulling the removal knob portion 42 with your fingers. Furthermore, when the sealing portion 40 is attached to the lid 30, it is preferable that the removal knob portion 42 extending downward is housed in a recess 31c provided on the outer circumference of the protruding portion 31. In this case, when the removal knob portion 42 is pushed in until it hits the bottom of the recess 31c, the removal knob portion 42 is positioned inside the groove of the male screw 31a provided on the outer circumference of the protruding portion 31. This prevents the removal knob portion 42 from obstructing the function of the male screw 31a.
[0039] (Ice pack bottle: Second embodiment) Figure 10 is a cross-sectional view (part 1) illustrating an ice pack bottle according to the second embodiment. Figure 11 is a cross-sectional view (part 2) illustrating an ice pack bottle according to the second embodiment. In the second embodiment, the ice pack bottle 1B uses an ice pack portion 20 in which the ice pack container 21 and the connecting portion 22 are integrally formed from a metal material. The metal material forming the ice pack portion 20 is, for example, aluminum or stainless steel. In this embodiment, aluminum is used. By integrally forming the ice pack container 21 and the connecting portion 22 from a metal material, the number of parts can be reduced.
[0040] In the ice pack bottle 1B according to the second embodiment, similar to the ice pack bottle 1A according to the first embodiment, the sealing portion 40 is attached to the lid 30 and integrally seals the space between the lid 30 and the main body opening 10h, and the space between the lid 30 and the ice pack opening 20h. This eliminates the need to construct the sealing portion 40 from multiple parts.
[0041] Figure 12 is a perspective view illustrating the ice pack portion applied to the ice pack bottle according to the second embodiment. Metal materials such as aluminum have a higher thermal conductivity than resin. Therefore, by forming the ice pack container 21 from a metal material such as aluminum, the temperature inside the ice pack container 21 is directly transferred to the affected area, allowing for effective cooling.
[0042] The ice pack opening 20h in the ice pack section 20 is formed by a connecting section 22 that is integrally formed with the ice pack container 21. The diameter of the ice pack opening 20h should be large enough to easily accommodate ice made in a household refrigerator (for example, 30mm to 35mm or larger).
[0043] Figure 13 is a perspective view illustrating the connection between the ice pack and the lid. Figure 14 is a cross-sectional view illustrating the connection between the ice pack and the lid. Since the ice pack portion 20 is screwed onto the lid 30 by the connecting portion 22, when the lid 30 is removed from the container body 10, the ice pack portion 20 is removed from the container body 10 together with the lid 30. Therefore, when using it as an ice pack, the lid 30 is removed from the container body 10, the ice pack portion 20 is removed from the container body 10, and the ice pack container 21 can be applied to the affected area with the lid 30 still attached to cool it.
[0044] Furthermore, as in the first embodiment, as shown in Figure 6, if the ice pack portion 20 is not attached to the lid 30, the container body 10 can be used as a beverage container by placing a beverage inside. That is, even with the ice pack portion 20 removed from the lid 30 (with only the lid 30), the lid 30 can be screwed onto the container body 10, and sealing can be performed using the same sealing portion 40. Thus, the lid 30 with the ice pack portion 20 removed and the container body 10 constitute a beverage container.
[0045] (Ice pack bottle: Third embodiment) Figure 15 is a cross-sectional view illustrating an ice pack bottle according to the third embodiment. Figure 16 is a perspective view illustrating the ice pack portion applied to the ice pack bottle according to the third embodiment. In the third embodiment of the ice pack bottle 1C, the ice pack container 21 of the ice pack section 20 is made of cloth. The ice pack section 20 has a cloth ice pack container 21, a connecting section 22 made of resin material, and an annular member 23 that connects the ice pack container 21 and the connecting section 22.
[0046] The ice pack container 21 is composed of, for example, a polyester outer layer and a PVC (Poly Vinyl Chloride) coated lining. The ice pack container 21, made of fabric, is shaped like an inverted cone that tapers towards the bottom, and has multiple pleats so that it expands when ice is placed inside.
[0047] The connecting portion 22 is made of, for example, polypropylene. The ice pack container 21 and the connecting portion 22 are connected by an annular member 23. For example, an aluminum ring member is used for the annular member 23, and the cloth ice pack container 21 and the resin connecting portion 22 are connected by sandwiching the upper part of the ice pack container 21 between the annular member 23 and the connecting portion 22.
[0048] The ice pack opening 20h in the ice pack section 20 is formed by an annular connecting section 22. The diameter of the ice pack opening 20h should be large enough to easily accommodate ice made in a household refrigerator (for example, 30mm to 35mm or larger).
[0049] In the ice pack bottle 1C according to the third embodiment, similar to the ice pack bottle 1A according to the first embodiment, the sealing portion 40 is attached to the lid 30 and integrally seals the space between the lid 30 and the main body opening 10h, and the space between the lid 30 and the ice pack opening 20h. This eliminates the need to construct the sealing portion 40 from multiple parts.
[0050] Figure 17 is a perspective view illustrating the connection between the ice pack and the lid. Figure 18 is a cross-sectional view illustrating the connection between the ice pack and the lid. Since the ice pack portion 20 is screwed onto the lid 30 by the connecting portion 22, when the lid 30 is removed from the container body 10, the ice pack portion 20 is removed from the container body 10 together with the lid 30. Therefore, when using it as an ice pack, the lid 30 is removed from the container body 10, the ice pack portion 20 is removed from the container body 10, and the ice pack container 21 can be applied to the affected area with the lid 30 still attached to cool it.
[0051] Furthermore, as in the first embodiment, as shown in Figure 6, if the ice pack portion 20 is not attached to the lid 30, the container body 10 can be used as a beverage container by placing a beverage inside. That is, even with the ice pack portion 20 removed from the lid 30 (with only the lid 30), the lid 30 can be screwed onto the container body 10, and sealing can be performed using the same sealing portion 40. Thus, the lid 30 with the ice pack portion 20 removed and the container body 10 constitute a beverage container.
[0052] As described above, according to this embodiment, the lid 30 and the container body 10, and the lid 30 and the ice pack portion 20 can be sealed with an integrated sealing portion 40, thus simplifying the structure of the sealing portion 40 and improving maintainability. Furthermore, even if the ice pack portion 20 is removed, the lid 30 can be screwed onto the container body 10, allowing it to be used not only as a portable ice pack, but also as a beverage container by removing the ice pack portion 20.
[0053] Although this embodiment and its application examples have been described above, the present invention is not limited to these examples. For example, while screw connections were shown for the connection between the lid 30 and the container body 10 and the connection between the lid 30 and the ice pack portion 20, other connections (e.g., fitting) are also applicable. Furthermore, any additions, deletions, or design modifications of components to the above-described embodiments or their application examples, or combinations of features from each embodiment, are also included within the scope of the present invention, as long as they retain the essence of the present invention.
