Description

Technical Field

[0001] The present invention relates to a heat-insulating and cold-preserving bottle.

Background Art

[0002] When going out in hot seasons, from the perspective of preventing heatstroke, it is preferable to drink water frequently for hydration and take appropriate breaks in cool places. For example, one might stop by a convenience store near the destination to buy and drink bottled drinking water, or take a short break in a store with effective air conditioning. However, there may be cases where there is no convenience store or the like at the destination, or even if there is, sufficient staying time cannot be ensured depending on the situation. Also, each time, there is the cost of purchasing bottled drinking water, and there is a problem that the coldness of the bottled drinking water is quickly lost under the high outdoor temperature after a short time.

[0003] In contrast, there are people who carry around a heat-insulating beverage bottle, commonly called a mug, with pre-chilled drinking water or ice added to it. In this case, even without a convenience store or the like, or even if there is no time to stop by a convenience store or the like, cold drinking water can be drunk at any time and anywhere, which has the advantages of being safe, convenient, and not costing much. If hydration is done frequently, heat can be easily dissipated from the skin due to the heat of vaporization from sweating, and the heat accumulated in the body can be released to prevent heatstroke. However, especially in very hot cases, it is preferable to further cool the neck and under the armpits to more efficiently suppress the rise in body temperature.

[0004] Therefore, some people carry a cooler bag containing a frozen wet towel and ice packs along with the aforementioned insulated beverage bottle. They hydrate with the water in the bottle and apply the wet towels and ice packs from the cooler bag to various parts of their body for icing. However, this makes their luggage bulky, and when they need to drink water and apply ice, they have to take the insulated beverage bottle and cooler bag out of the bag separately and put them back in. Furthermore, their hands, which are directly holding the frozen wet towels, may become excessively cold and painful. Their handkerchief may also get soaked with water from the melting ice on the wet towels or condensation on the ice packs, making it difficult to wipe their hands clean.

[0005] As an idea for carrying drinking water and a wet wipe together, a recess has been proposed in the side of a beverage bottle, extending from the outside inward to store the wet wipe. This recess is then covered with an outer material, and the outer material is torn open to remove the wet wipe when needed (see, for example, Patent Document 1). However, this does not keep the drinking water or wet wipe cool, and once the outer material is torn open, the wet wipe cannot be stored again. [Prior art documents] [Patent Documents]

[Modes for carrying out the invention]

[0023] (Beverage container 1) A beverage container 1 according to one embodiment of the present invention will be described with reference to the drawings. Figures 1 and 2 are a perspective view and a front view of the beverage container 1. As shown in Figures 1 and 2, the beverage container 1 is formed in a generally cylindrical shape and has an insertion opening 73a at the top into which a finger can be inserted, and is provided with a handle 73 for gripping by the user. Figure 3 is a cross-sectional view of the beverage container 1, Figure 4 is a perspective view showing the beverage container 1 separated into two components, the cooling section 2 and the beverage storage section 3, and Figure 5 is a perspective view showing the beverage storage section 3 (composed of a storage section body 4, a lid 7, and an ice stopper 8) with the detachable lid 7 removed. The cooling section 2 is a bottomed cylindrical insulated container, and the beverage storage section 3 is a watertight liquid storage container into which beverages such as drinking water or ice can be directly poured through a drinking spout 52 and the drinking spout 52 is closed with a lid 7.

[0024] As shown in Figure 3, the beverage container (insulated bottle) 1 houses a non-insulated cylindrical container (non-insulated container) 6 located below the beverage storage section (liquid storage section) 3 in an insulated cooling section (insulated container) 2. A sleeve 5 located above the cylindrical container 6 is detachably engaged with the upper opening 2a of the cooling section 2, and the upper opening 2a is closed with the sleeve 5, thereby integrating the cooling section 2 and the beverage storage section 3 in a separable manner. This allows cold beverages such as drinking water or ice poured in through the mouthpiece (cylindrical opening) 52 to be stored in the cylindrical container 6 and carried around while being kept cool in the cooling section 2.

[0025] As shown in Figure 5, by keeping the cooling section 2 and the beverage storage section 3 integrated and removing only the lid 7 that covers and closes the drinking spout 52, the user can directly drink the beverage stored in the cylindrical container 6 by gripping the cylindrical cooling section 2 with their hand and putting their mouth to the exposed drinking spout 52, similar to conventional insulated beverage bottles. Also, as shown in Figure 4, the beverage storage section 3, which is detachable from the cooling section 2, can be separated and removed with the lid 7 still closed, and by gripping the handle 73 provided on the lid 7, the cylindrical container 6 filled with beverage or ice can be used as an ice pack to cool various parts of the body by applying it to the skin or clothing. By sealing water, beverage, etc., in the beverage storage section 3 removed from the cooling section 2 and leaving it in a freezer for a predetermined time, it can be frozen as is.

[0026] (Insulated section 2) Figure 6 is a cross-sectional view of the cooling section 2. As shown in Figure 6, the cooling section 2 is a bottomed cylindrical metal container with a vacuum double-walled structure that provides heat insulation, consisting of an outer cylinder 21 and an inner cylinder 22 housed inside it. Both the outer cylinder 21 and the inner cylinder 22 are formed in a bottomed cylindrical shape consisting of body portions 21a, 22a and bottom portions 21b, 22b, and the dimensions of the inner cylinder 22 are set to be slightly smaller than those of the outer cylinder 21 in both the radial and vertical directions. As a result, a vacuum gap 2S that serves as an insulating space is provided between the outer cylinder 21 and the inner cylinder 22, and the upper edges 21c, 22c of the respective body portions 21a, 22a are joined to each other in order to seal the gap 2S.

[0027] Specifically, the body portion 21a of the outer cylinder 21 is vertical from the bottom end to the top end, while the body portion 22a of the inner cylinder 22 is also vertical from the bottom end to the vicinity of the upper opening 2a, similar to the outer cylinder 21. However, the upper opening 2a is slightly enlarged, forming a band-shaped enlarged portion 22d with a predetermined width in the vertical direction. The upper end edge 22c above this portion is further enlarged and comes into contact with the upper end edge 21c of the outer cylinder 21, and this portion is joined by welding or the like.

[0028] Furthermore, a female screw 22e is provided on the inner circumference of the upper opening 2a (band-shaped enlarged diameter section 22d), and a first male screw 51a (described later) provided on the outer circumference of the sleeve 5 of the storage section body 4 is screwed into this female screw 22e, thereby engaging the inner circumference of the upper opening 2a and the outer circumference of the sleeve 5 in a removable manner, and the cooling section 2 and the beverage storage section 3 (storage section body 4) are detachably integrated. The threads of the female screw 22e protrude inward from the upper opening 2a, but because it is provided on the band-shaped enlarged diameter section 22d, it is approximately the same diameter as the lower part of the body 22a when viewed from above, and is designed so as not to affect the insertion and removal of the cylindrical container 6. In addition to keeping the water etc. placed in the cylindrical container 6 cool, the cooling section 2 also protects the silicone rubber cylindrical container 6 from damage.

[0029] (Beverage storage section 3) Figures 7 and 8 are perspective and cross-sectional views showing the beverage storage section 3 with the lid 7, which covers and watertightly closes the cylindrical drinking spout 52 protruding from its upper surface, and the ice stopper 8, which is located behind the drinking spout 52 and divides the flow path of the beverage into smaller sections, removed. Figure 9 is an enlarged cross-sectional view of the upper part of only the beverage storage section 4, and Figure 10 is an enlarged cross-sectional view of the upper part of the beverage container 1 (with the beverage storage section 3 engaged with the cooling section 2).

[0030] As described above, the beverage storage section 3 is a watertight beverage storage container (liquid storage container) composed of a storage section body 4, a lid 7, and an ice stopper 8. By removing the lid 7, one can drink directly from the drinking spout 52. When the drinking spout 52 is closed, the handle 73 provided on the top surface of the lid 7 can be grasped, and the cylindrical container 6 containing chilled beverages can be used as an ice pack to be applied to various parts of the body.

[0031] (Storage unit body 4) As shown in Figures 7 to 9, the storage unit body 4 is composed of an engaging portion 51 which is generally cylindrical and has a through hole that penetrates in the vertical direction and is detachably engaged with the cooling unit 2, a drinking spout 52 which is generally straight cylindrical in shape and has its opening closed by being covered by a lid 7, a sleeve 5 which is generally cylindrical in shape and has an annular portion 53 which is formed integrally and coaxially between the engaging portion 51 and the drinking spout 52, and a molded, non-insulating cylindrical container 6 which is bottomed cylindrical and has its upper opening 6a fixed in a watertight manner to the lower part of the sleeve 5 and is provided to extend downward below the engaging portion 51.

[0032] (Sleeve 5) The sleeve 5 is made of hard plastic and is generally cylindrical in shape with a through hole that penetrates vertically. As shown in Figures 9 and 10, the lower end has a cylindrical engaging portion 51 on its outer circumference, which has a first male screw 51a that screws into the female screw 22e (Figure 10) of the cooling portion 2. The upper end of the sleeve 5 has a second male screw 52a on its outer circumference that screws into the female screw 71a (Figure 8) of the lid 7, while the inner circumference has a smooth drinking spout 52 without any steps. Furthermore, between the engaging portion 51 at the lower end and the drinking spout 52 at the upper end, there is an annular portion 53 that has an outer diameter larger than the engaging portion 51 and the drinking spout 52, and protrudes radially from the sleeve 5, forming a headband shape.

[0033] The first male screw 51a and the female screw 22e of the cooling section 2 can be loosened by rotating the sleeve 5 counterclockwise relative to the cooling section 2 when viewed from above, and the second male screw 52a and the female screw 71a of the lid 7 can be loosened by rotating the lid 7 counterclockwise relative to the sleeve 5 when viewed from above. The reason for not making these rotation directions opposite (clockwise and counterclockwise) is to avoid the user having to think about which direction to rotate each time they attach or detach the lid 7 to the sleeve 5 and attach or detach the storage section body 4 to the cooling section 2, which would make the operation less intuitive.

[0034] As shown in Figure 10, the engaging portion 51 engages with the cooling portion 2 in a way that allows it to be housed inside the cooling portion 2 and close the upper opening 2a, by screwing its outer circumference into the inner circumference of the upper opening 2a of the cooling portion 2. This isolates the cylindrical container 6 extending below the engaging portion 51 from the outside, maintaining the cooling state of the beverage stored inside the cylindrical container 6, and also integrates the cooling portion 2 and the storage portion body 4 in a separable manner. As shown in Figures 4 and 7 to 9, the drinking spout 52 is formed to protrude from the upper part of the sleeve 5 in a roughly straight cylindrical shape and is located above the engaging portion 51 that engages with the upper opening 2a of the cooling portion 2. Therefore, the user can hold the outer circumference of the cooling portion 2 while the storage portion body 4 is engaged with the cooling portion 2, and drink the beverage stored inside the storage portion body 4 directly by putting their mouth to the drinking spout 52 that protrudes upward.

[0035] The drinking spout 52 has a cylindrical shape with a thin radial thickness at the upper edge 52b having an opening, and the inner circumference is smoothly formed, so the user can easily catch the beverage flowing from the drinking spout 52 with their mouth and will not spill the beverage. Furthermore, as shown in Figure 10, when the lid 7 is attached, the drinking spout 52 is housed inside the lid 7, and the entire spout, including not only the upper opening but also the outer surface, is covered by the lid 7 and is not exposed to the outside, so there is no need to worry about soiling it when carrying it and it can be kept in a clean state. On the inside of the drinking spout 52, as will be described later, an inclined surface 52c is formed that slopes downward from the middle in the vertical direction so that the inner diameter decreases, so that the watertight material 74 provided on the inner lid 72 of the lid 7 can be tightly sealed.

[0036] As shown in Figure 10, when the cooling section 2 and the sleeve 5 are screwed together, the lower end surface 53a of the annular section 53 abuts against the upper end surface 2b of the upper opening 2a of the cooling section 2 all the way around, filling the gap between the cooling section 2 and the sleeve 5. Therefore, even though the cooling section 2 is made of metal and the sleeve 5 is made of hard plastic, the beverage stored in the cylindrical container 6 can be kept cool without the need for a watertight material to seal off the cold air between the cooling section 2 and the sleeve 5. Accordingly, although a watertight material is not provided in this embodiment, it is of course possible to fix an annular watertight material that is in close contact with the upper end surface 2b of the cooling section 2 to the lower end surface 53a in order to obtain higher cooling performance.

[0037] The annular portion 53 has an outer diameter larger than the engaging portion 51 and the drinking spout 52, but is set to be approximately the same diameter as the outer diameter of the cooling portion 2. As shown in Figures 1, 2, and 5, the outer surface 53b is continuous with the outer surface 2c of the cooling portion 2 in a nearly flush manner without any step difference. Furthermore, as will be described later, the lid 7 has a smaller diameter than these. Therefore, when placing the beverage container 1 into a bag containing other items, the outer surface of the beverage container 1 can be smoothly inserted all the way to the bottom of the bag without catching on other items, thus avoiding the inconvenience of damaging books by catching the part of the outer surface of the insulated bottle 1 protruding from the top or bottom of the books.

[0038] However, since the annular portion 53 serves as a gripping portion when rotating it relative to the cooling portion 2 in order to attach or detach the beverage storage portion 3 (storage portion body 4), numerous radially recessed recesses 53c are provided on the outer peripheral surface 53b at intervals in the circumferential direction, as shown in Figures 1, 2, and 5, to provide a non-slip surface that makes it easier to grip. If the portion were convex, it would protrude outward from the outer peripheral surface 2c of the cooling portion 2 and risk getting caught on other luggage when placed in a bag, but it is also possible to provide convex portions instead of recesses, or to provide both recesses and convex portions.

[0039] Incidentally, the sleeve 5 is not a single molded product, but as shown in Figure 9, it is composed of three cylindrical members (sleeve body 5a, first auxiliary sleeve 5b, and second auxiliary sleeve 5c). The sleeve body 5a is a cylindrical member that forms a through hole that penetrates the inside of the sleeve 5 in the vertical direction. A flange-like body forming an annular portion 53 is formed protruding from the middle of the outer circumference in the vertical direction, and a cylindrical drinking opening 52 is formed on the upper side of the flange-like body. A conical tube portion 5d that tapers downward in a frustoconical shape and a straight tube portion 5e that hangs down without a step from its lower end are formed on the lower side of the flange-like body. The inner circumferential surface of the conical tube portion 5d is formed to be continuous with the inclined surface 52c of the drinking opening 52 without a step, and an engaging projection 5f is provided on the inner circumferential surface of the straight tube portion 5e that engages with the hook groove 81 of the ice stopper 8, which will be described later, to support the ice stopper 8.

[0040] As shown in Figure 9, the first auxiliary sleeve 5b is a cylindrical member that forms the outer circumference of the engagement portion 51, on which a first male screw 51a is formed on the outer circumference. The flange 6b formed on the periphery of the upper opening 6a of the cylindrical container 6 and the hook-shaped portion 6c formed on its outer circumference are sandwiched between the first auxiliary sleeve 5b and the second auxiliary sleeve 5c, a cylindrical member fitted inside it. Furthermore, these are fitted onto the conical cylindrical portion 5d and the straight cylindrical portion 5e, and the lower circumferential surface of the flange 6b is sandwiched between the sleeve body 5a and the first auxiliary sleeve 5b, thereby securing the upper opening 6a of the cylindrical container 6 in a watertight manner so that it does not come off the sleeve 5.

[0041] (cylindrical container 6) As shown in Figures 4, 7, and 8, the cylindrical container 6 is a bottomed, cylindrical, non-insulating container that extends straight in a rod shape below the engaging portion 51 of the sleeve 5. It is molded from a translucent elastic elastomer (e.g., silicone rubber) and is set to a hardness such that it hardly deforms even when filled with beverage. As shown in Figure 10, the periphery of the upper opening 6a of the cylindrical container 6 has a flange 6b that protrudes in the outer diameter direction and a hook-shaped portion 6c that extends in both the up and down directions at its outer peripheral end. As described above, these and the circumferential surface below them are sandwiched by the components of the sleeve 5 and fixed watertight to the lower opening of the through hole of the sleeve 5. As a result, the upper opening 6a communicates with the drinking spout 52 through the through hole of the sleeve 5, allowing beverages to be poured into the cylindrical container 6 from the drinking spout 52, or beverages stored in the cylindrical container 6 to be drunk from the drinking spout 52.

[0042] The opening 6a of the cylindrical container 6 is formed to be smaller in diameter than the outer circumference of the engaging portion 51 (first auxiliary sleeve 5b) in order to be sandwiched inside the engaging portion 51. However, the diameter is expanded radially below the engaging portion 51 to ensure a sufficient volume for storing beverages. Because the cylindrical container 6 is semi-transparent, the remaining amount of beverage water and the state of the ice stored inside can be visually checked from the outside. Since it is made of elastic silicone rubber, it feels good against the skin, and even when filled with water and frozen in a freezer, it expands by stretching, absorbing the expansion and preventing it from tearing. On the other hand, it maintains its original cylindrical shape with almost no deformation even when filled with water, so it does not freeze into an irregular shape that prevents it from being inserted (stored) in the insulated container 2. However, since expansion due to freezing water is unavoidable, a larger gap is provided between the container and the inner surface of the insulated container 2 to allow for easy insertion and removal.

[0043] (Lid 7) As shown in Figures 7, 8, and 10, the lid 7 comprises an outer lid 71 formed in a cylindrical shape with a closed top, an inner lid 72 having a cylindrical stopper 72a provided in the center of the inner lower surface of the outer lid 71 and protruding downward, and a handle 73 provided on the upper part of the outer lid 71. The outer lid 71 is detachable from the storage body 4 by having a female thread 71a on its inner circumferential surface that screws into the second male thread 52a of the drinking spout 52, and when screwed onto the drinking spout 52, the lower end edge 71b abuts against the upper end surface 53d of the annular portion 53, thereby covering the entire drinking spout 52, including its outer circumference. The stopper body 72a of the inner lid 72 is provided with an annular watertight material 74 on the outer circumference of its lower end. When the outer lid 71 is screwed onto the drinking spout 52 with the stopper body 72a inserted inside the drinking spout 52, the watertight material 74 is pressed against the inclined surface 52c of the drinking spout 52 and tightly adheres to it by elastic deformation, thereby sealing the drinking spout 52 watertight.

[0044] As shown in Figures 1 to 5, the handle 73 is U-shaped and downward-facing, with both ends fixed to connect the diametrically aligned ends of the upper surface of the outer lid 71, so as to protrude upward. This creates a roughly rectangular insertion opening 73a between the horizontally elongated portion 73b that extends straight in the diametrical direction and the upper surface of the outer lid 71, allowing the user to insert their fingers into the insertion opening 73a and grasp the horizontally elongated portion 73b. As described above, the handle 73 is used when removing the beverage storage section 3 from the cooling section 2 and holding the cylindrical container 6 against the body, and can also be used to make it easier to carry, for example by wearing a harness and draping it over the body, or to prevent the cylindrical container 6 from being dropped on the ground and soiled.

[0045] To at least allow fingertips to be inserted and make it easier to grasp the elongated portion 73b, it is not necessarily required to be open; the insertion part may be formed by a recess. Incidentally, the outer diameter of the outer lid 71 is set to be smaller than the annular portion 53 of the storage unit body 4 all around. This is to prevent accidentally loosening the lid 7 by accidentally catching a finger on the outer lid 71 when rotating the annular portion 53 to remove the storage unit body 4 from the cooling device 2.

[0046] (Ice stopper 8) As shown in Figures 7, 8, and 10, the ice stopper 8 comprises a ring-shaped body 81 with a hook groove 81a formed on its outer circumference to serve as a locking portion, a crossbar 82 that spans the inside of the ring-shaped body 81 and divides the opening into four (or more) sections, and a gripping piece 83 provided on the upper part of the crossbar 82. By pinching the gripping piece 83 with the fingers and inserting the ice stopper 8 into the back of the drinking spout 52 and rotating it, the hook groove 81a of the ring-shaped body 81 is detachably locked to the engaging projection 5f protruding from the sleeve 5, thereby attaching it to the straight cylindrical section 5e at the back of the drinking spout 52. By providing the ice stopper 8, the beverage flow path opening is divided into smaller sections, preventing ice placed in the cylindrical container 6 from flowing out when drinking. Furthermore, an annular groove 81b is formed separately from the hook groove 81a on the outer circumference of the ring-shaped body 81, and an annular packing 84 is fitted into it. By making the packing 84 tightly adhere to the inner surface of the sleeve 5, the ice stopper 8 is prevented from unexpectedly coming off while drinking water.

[0047] (Features and effects of beverage container 1) [1] The beverage container (insulated bottle) 1 is composed of a bottomed cylindrical insulated section (insulated container) 2 having an upper opening 2a, and a generally cylindrical sleeve 5 formed such that a straight cylindrical drinking spout (tubular opening) 52 protrudes upward and is covered and closed by a removable lid 7 on top, and a straight cylindrical cylindrical container (non-insulated container) 6 which extends downward from the sleeve 5 and stores beverages (liquids) such as water that are poured in or drunk through the drinking spout 52, thereby forming a generally cylindrical shape, and the cylindrical container 6 is housed in the insulated section 2 and the sleeve 5 is detachably engaged with the upper opening 2a to close the upper opening 2a, thereby integrating the insulated container 2 and the beverage storage section 3 so as to be separable.

[0048] The above-mentioned features [1] provide the following effects. As shown in Figures 1 to 3, the cooling section 2 and the beverage storage section 3 are integrated and the cylindrical container 6 is sealed from the outside air, allowing the chilled beverage such as water stored in the cylindrical container 6 to be carried around while remaining chilled. Furthermore, as shown in Figure 4, for example, with the drinking spout 52 closed with the lid 7, the beverage storage section 3, which is roughly cylindrical and rod-shaped, can be removed from the cooling section 2, and by gripping the sleeve 5 or lid 7 at the upper end (one end), the rod-shaped cylindrical container 6 containing chilled water, etc., at the lower end (the other end) can be used as an ice pack to cool various parts of the body. Moreover, as shown in Figure 5, by opening the lid 7 while the cooling section 2 and the beverage storage section 3 remain engaged, the cooling section 2, which is thermally sealed from the cylindrical container 6 containing the cold beverage, can be gripped, and the cold beverage can be drunk directly from the drinking spout 52 that is exposed to the outside.

[0049] In other words, the beverage container 1 can serve both the purpose of a conventional insulated mug bottle filled with chilled water and a cooler bag filled with chilled hand towels. In particular, the drinking spout 52 is kept clean because it is completely covered by the lid 7, so the user can drink the stored beverage by directly putting their mouth to the spout 52 without worrying about hygiene. Also, unlike conventional insulated mug bottles, the beverage storage section 3 can be placed in the freezer after being removed from the cooling section 2, so there is no need to transfer ice frozen in an ice tray, and there is no need to touch it with your hands, making it hygienic in that respect as well.

[0050] [2] The beverage container 1 is composed of a bottomed cylindrical cooling section 2 having an upper opening 2a, a storage section body 4 having a generally cylindrical sleeve 5 formed at the top such that a straight cylindrical drinking spout 52 protrudes upward, and a non-insulating, generally cylindrical cylindrical container 6 that is provided to extend straight downward from the sleeve 5 by watertightly fixing the upper opening 6a to the sleeve 5 and has shape retention, and a cylindrical lid 7 integrally formed on the upper surface such that a handle 73 that can be grasped by the user protrudes upward, and is detachably attached by screwing onto the outer circumference of the drinking spout 52 so as to cover and close the entire drinking spout 52, and together with the storage section body 4 forms a watertight beverage storage section 3, characterized in that the cooling section 2 and the beverage storage section 3 are detachably integrated by storing the cylindrical container 6 in the cooling section 2 and engaging the sleeve 5 with the upper opening 2a to close the upper opening 2a.

[0051] Due to the features described in [2] above, in addition to the effects of the features described in [1] above, the following effects are achieved: In the beverage storage section 3, a non-insulating, shape-retaining cylindrical container 6 that serves as an ice pack is provided to extend straight downward in a rod shape. Therefore, even when held at an angle, it does not sag like conventional bag-shaped ice packs, and can be intuitively applied to parts of the body that cannot be directly seen (for example, the back). Moreover, a handle 73 that protrudes upward is provided on the lid 7 located at the top opposite the cylindrical container 6 that is located at the bottom of the beverage storage section 3 and extends straight downward in a rod shape. Therefore, by grasping the handle 73, the reach of the cylindrical container 6 is expanded, and the cylindrical container 6 can be applied accurately and easily to places that are normally difficult to reach (for example, the middle of the back). Furthermore, the lid 7, which has a handle 73 formed on it, is attached to the cylindrical container 6 by screwing it onto the sleeve 5. Since it will not separate unless it is intentionally rotated relative to the lid, it prevents the storage unit body 4 from suddenly coming off when used as an ice pack, and prevents the cylindrical container 6 from being dropped on the ground and puncturing.

[0052] [3] The beverage container 1 is characterized in that the handle 73 has an insertion opening 73a on its upper surface that allows the user to insert their fingers and grip it. As mentioned above, it is not limited to an insertion opening, but may also be provided as a recessed insertion part into which only the fingertip can be inserted.

[0053] The above-mentioned features [3] provide the following effects: Since the lid 7 has a handle 73 with an insertion opening 73a into which a finger can be inserted, by inserting a finger into the insertion part 73a and gripping the handle 73, it is possible to firmly press it against parts of the body that are difficult to reach, thus preventing inconveniences such as dropping the beverage storage part 3 on the ground and soiling, scratching, or puncturing the cylindrical container 6.

[0054] [4] The beverage container 1 is characterized in that the cylindrical container 6 is made of an elastic elastomer molded product (silicone rubber molded product) and has non-thermal insulation properties and shape retention.

[0055] The above-mentioned features [4] provide the following benefits: Because the non-insulating cylindrical container 6 is made of an elastic elastomer molded product (silicone rubber molded product), its surface is soft, so when the cylindrical container 6 is removed from the cooling section 2 and used as an ice pack, it feels good against the skin. Also, because it is elastic, even when filled with water and frozen in a freezer, it stretches and absorbs the expansion, so it does not tear.

[0056] [5] The beverage container 1 is a molded product in which the cylindrical container 6 is formed in such a shape that it can be stored inside the cooling section 2 by passing through the upper opening 2a without being deformed.

[0057] The above-mentioned features [5] provide the following benefits: Because the cylindrical container 6 is molded in a shape that allows it to pass through the upper opening 2a without deformation and be stored inside the cooling section 2, it can always be stored inside the cooling section 2 even when the cylindrical container 6 is filled with water and frozen, making it difficult to deform its outer shape. Therefore, there is no need to worry about the state after freezing when you are about to freeze it.

[0058] [6] The beverage container 1 is characterized in that the cooling section 2 and the beverage storage section 3 are detachably integrated by screwing a male screw 51a provided on the outer circumference of the sleeve 5 into a female screw 22e provided on the inner circumference of the upper opening 2a of the cooling section 2 to close the upper opening 2a.

[0059] The above-mentioned features [6] provide the following effects: Since the sleeve 5 and the cooling section 2 are screwed together to integrate the cooling section 2 and the beverage storage section 3, they will not separate unless they are intentionally rotated relative to each other. For example, the cylindrical container 6 may accidentally detach from the cooling section 2 in a bag, preventing the liquid stored in the cylindrical container 6 from becoming warm, the ice from melting, or condensation from forming on the surface of the cylindrical container 6, which could wet the bag or its contents.

[0060] [7] The beverage container 1 is made of a generally cylindrical hard plastic and has a drinking spout 52 formed on its upper end and an engaging portion 51 formed on its lower end, which is cylindrical and has a male thread 51a on its outer circumference that is screwed into the female thread 22e. The sleeve 5 has a drinking spout 52 formed on its upper end and an engaging portion 51 formed on its lower end, which is cylindrical and has a male thread 51a on its outer circumference that is screwed into the female thread 22e. Between the drinking spout 52 and the engaging portion 51, there is an annular portion 53 which has an outer diameter that is approximately the same as or larger than the outer diameter of the drinking spout 52 and forms a headband shape. The cylindrical container 6 is placed in the drinking spout 2 and the male thread 51a and the female thread 22e are screwed into each other to close the upper opening 2a, thereby separating the drinking spout 2 and the storage portion body 3 into a single unit, and the lower end surface 53a of the annular portion 53 and the upper end surface 2b of the upper opening 2a of the drinking spout 2 are in contact with each other over the entire circumference.

[0061] The above-mentioned features [7] provide the following effects: The lower end surface 53a of the annular portion 53 and the upper end surface 2b of the upper opening 2a of the cooling portion 2 come into contact with each other all around, which reduces the gap at the joint between the cooling portion 2 and the storage portion body 3, making it difficult for the cold air inside the cooling portion 2 to escape to the outside. As a result, even with a metal cooling portion 2 and a hard plastic sleeve 5, high cooling performance can be achieved without providing a watertight material to block the cold air between them.

[0062] [8] The beverage container 1 is characterized in that the annular portion 53 is formed to be approximately the same diameter as the cooling portion 2, and the lid 7 is cylindrical and has a smaller outer diameter than the annular portion 53.

[0063] The above-mentioned features [8] provide the following effects: The outer surface 53b of the ring portion 53 is flush with the outer surface 2c of the cooling portion 2 with almost no step difference, and the lid 7 above it has a smaller diameter than these. As a result, there are no radially protruding protrusions on the outer surface of the beverage container 1, and when inserting or removing the beverage container 1 from a bag containing other items, the outer surface does not catch on other items, and it can be smoothly inserted all the way to the bottom of the bag. In addition, by making the lid 7 small in diameter, it is possible to avoid accidentally catching a finger on the lid 71 and loosening it when rotating the ring portion 53 to separate the cooling portion 2 and the storage portion body 4.

[0064] [9] The beverage container 1 is characterized in that the outer surface 53b of the annular portion 53 has radially recessed recesses provided at intervals in the circumferential direction.

[0065] Due to the features described in [9] above, the annular portion 53 serves as a gripping portion when the beverage storage portion 3 is rotated relative to the cooling portion 2 for attachment or removal. The outer circumferential surface 53b is provided with numerous radially recessed recesses 53c, which act as a non-slip surface to make it easier to grip. The protruding portion is recessed because it could get caught on other items when taking the bag in and out as described above.

[0066]

[10] The beverage container 1 is characterized in that the rotational direction relative to the sleeve 5 when removing the lid 7 and the rotational direction relative to the cooling section 2 when separating the storage section body 3 are set to be the same direction when viewed from above, and a watertight material is provided between the sleeve 5 of the lid 7 that is tightly sealed to both when screwed together, while no watertight material is provided between the cooling section 2 and the sleeve 5.

[0067] According to the features described in

[10] above, the loosening direction of the lid 7 and the loosening direction of the storage unit body 3 are set to be the same when viewed from above. Therefore, when removing the lid 7 or separating the storage unit body 3 from the cooling unit 2, the user can intuitively operate by changing the part they grip and rotating in the same direction. In addition, by providing a watertight material between the lid 7 and the sleeve 5 that tightly seals both when screwed together, while not providing a watertight material between the cooling unit 2 and the sleeve 5, even if the user accidentally grips the cooling unit 2 and rotates the lid 7 when separating the storage unit body 3, the cooling unit 2 and sleeve 5, which have little rotational resistance because there is no watertight material between them, will be loosened, thus preventing the lid 7 from being accidentally opened and the contents spilling out.

[0068] (Modified version of the above embodiment) In the above embodiment, the beverage container 1 has a metal insulated container with a vacuum gap between the outer cylinder 21 and the inner cylinder 22 for the cooling section 2. However, instead of a vacuum gap, an insulating material such as polystyrene foam or urethane material may be interposed. If an insulating material is used, a vacuum is not necessary, so instead of a metal outer cylinder and inner cylinder, the outer casing (outer cylinder) and inner casing (inner cylinder) that form the insulating space between them may be made of plastic or a waterproof sheet. In that case, the cooling section 2 does not need to be a rigid container and may be a soft, deformable bag-shaped container.

[0069] In the above embodiment of the beverage container 1, screws are provided on the inner circumference of the upper opening 2a of the cooling section 2 and the outer circumference of the beverage storage section 3 (sleeve 5) to removably engage the cooling section 2 and the beverage storage section 3 and close the upper opening 2a by screwing them together. Alternatively, a flange with a downward-facing L-shaped cross-section may be formed on the outer circumference of the beverage storage section 3 (sleeve 5), with female screws on the inner circumference of the flange, while male screws may be provided on the outer circumference of the upper opening 2a of the cooling section 2, and these screws may be screwed together. Alternatively, an engaging member made of an elastic material such as rubber may be provided on one or both of the cooling section 2 and the beverage storage section 3, and the engaging member may be fitted with an engaging member or engaged part provided on the other side.

[0070] In the above embodiment, the beverage container 1 is closed by covering the drinking spout 52 with a removable lid 7, but instead, a hinged lid may be used. For example, a lid may be provided with one end (fixed end) hinged to a sleeve 5 and the other end (free end) having a locking mechanism that can be releasedly locked to the sleeve 5. By closing and locking the lid, the entire drinking spout 52 is covered and the opening of the drinking spout 52 is closed, and when the lock is released and the lid is opened, the drinking spout 52 is exposed to the outside. Note that the drinking spout 52 does not have to be a straight cylinder; for example, it may be formed so that its diameter widens towards the top.

[0071] In the above embodiment, the beverage container 1 employs a cylindrical container 6 molded from silicone rubber into a straight, rod-like shape as a non-insulating container for storing beverages. However, instead, a bag-shaped container made of a waterproof sheet or the like, which does not necessarily have a fixed shape, may be used. Although this embodiment describes a beverage container, it can of course also be used simply as an insulated bottle equipped with an ice pack. [Explanation of Symbols]
