Description
[Technical field]
[0001] The present invention relates to a bottle cover for cooling and heating that can store a bottle having a substantially bottomed cylindrical body, a neck with a removable cap attached via an approximately inverted funnel-shaped shoulder, and keep the bottle cool or warm. [Background technology]
[0002] Beverages such as water and tea are often sold in bottles. As is well known, such bottles generally have a generally cylindrical body with a bottom, a cylindrical neck with a removable cap, and a generally inverted funnel-shaped shoulder. Bottled beverages are usually sold at the ideal drinking temperature, either chilled or heated, but plastic bottles, the most common type of beverage bottle, are made from thin synthetic resins such as polyethylene terephthalate, which have poor heat retention and return to room temperature in a relatively short period of time. Therefore, there have been bottle covers for storing PET bottles and keeping the beverage cold or hot in order to maintain the ideal drinking temperature for a long time (see Patent Document 1).
[0003] The bottle cover for keeping things cool and warm described in Patent Document 1 includes an insulated container with a thermal insulation structure and a press lid with a hole that is attached by screwing onto a male screw formed on the outer periphery of the upper part of the insulated container. A PET bottle is stored in the insulated container, and the press lid is placed on the insulated container so that the neck of the PET bottle protrudes from the hole in the press lid. Furthermore, the shoulder and bottom of the PET bottle are pressed vertically in the internal space of the insulated container by tightening the screw of the press lid, and the PET bottle is fixed in this pressed state. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Special Publication No. 8-25585 Summary of the Invention [Problem to be solved by the invention]
[0005] The bottle cover for keeping things cool and warm in Patent Document 1 presses the shoulder and bottom of the PET bottle in vertical directions by tightening the screws of the pressure lid, and the PET bottle is fixed in place by this tightening force, so the pressure lid needs to be tightened tightly. However, some of today's PET bottles have thin walls in order to conserve resources, and if the press-on lid is tightened too much, the force can cause the bottle to deform. In addition, the press-on lid needs to be turned and tightly tightened to secure the PET bottle, which is difficult for elderly people and others with limited finger movement to use. Furthermore, if the lid is not tightened enough, there is a risk that the press-on lid of the bottle cover for cooling and heating may come off when pouring a drink.
[0006] The present invention has been made in consideration of the above, and an object of the present invention is to provide a cold / warm bottle cover that can easily and reliably secure a stored bottle. [Means for solving the problem]

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The bottle cover 1 of the present invention is intended to store a bottle 2 containing a beverage such as water, tea, or coffee and to maintain the beverage at the ideal drinking temperature for a long period of time. A typical example of a bottle 2 that can be kept cool or warm is a plastic bottle. As is well known, such a bottle 2 generally consists of a generally bottomed, cylindrical body 2a, a cylindrical neck 2c equipped with a removable screw cap 2b, and a generally inverted funnel-shaped shoulder 2d. Bottles come in both hard and highly rigid varieties, and soft varieties that can be easily crushed.
[0019] The bottle cover 1 of the embodiment comprises a cylindrical insulated container 3 with a bottom capable of housing a body 2a of a bottle 2, and an upper lid 5 that is placed over an opening 4 of the insulated container 3. The heat-insulating container 3 is made of stainless steel and has a heat-insulating structure in which a double-walled sealed space 6 is evacuated.
[0020] The top lid 5 is made entirely of rubber (silicone rubber in this embodiment) and has a cylindrical portion 7 that can fit around the upper outer periphery of the insulated container 3, and a donut-shaped elastic damping portion 9 that is formed from the top of the cylindrical portion 7 toward the inside of the insulated container 3 and has a through hole 8 in the center that is slightly larger in diameter than the neck 2c of the bottle 2.
[0021] The cylindrical portion 7 of the upper lid 5 is an elastic ring-shaped band made of silicone rubber, with an inner diameter that is slightly smaller than the outer diameter of the upper part of the insulated container 3. Therefore, when fitted onto the upper part of the insulated container 3, a tightening force due to the elasticity of the rubber acts, and the tightening force and the frictional force of the rubber keep the upper lid 5 attached to the insulated container 3. As shown in the enlarged view of FIG. 5, the range from the upper end of the inner peripheral surface of the cylindrical portion 7 to the starting end of the enlarged diameter portion 10 described later becomes the fitting allowance 11a that can exert a frictional force by adhering to the insulated container 3, but this fitting allowance 11a is set to be larger than the fitting allowance 11b required for mounting and holding the upper part of the insulated container 3 with a margin. Therefore, depending on the difference in length between the actual fitting allowance 11a formed on the cylindrical portion 7 and the minimum necessary fitting allowance 11b, bottles 2 of different heights can be flexibly accommodated, as shown by the solid line and the imaginary line in the enlarged view of FIG. 5. Incidentally, the solid line in the enlarged view of FIG. 5 corresponds to a state corresponding to a tall bottle 2, and the imaginary line in the enlarged view of FIG. 5 corresponds to a state corresponding to a short bottle 2. Note that the fitting allowance 11b required for mounting and holding the upper part of the insulated container 3 has a certain practical range due to factors such as the wetness of the surface of the insulated container 3, the temperature of the cylindrical portion 7, or aging deterioration of the rubber, so the actual fitting allowance 11a may be larger than that in consideration of these factors.
[0022] A tapered expanded diameter portion 10 expanding downward is formed on the inner peripheral surface of the lower end of the cylindrical portion 7, which creates a gap 12 that opens downward between the cylindrical portion 7 and the outer peripheral surface of the insulated container 3. This gap 12 can be used to easily roll up the lower end of the cylindrical portion 7, making it extremely easy to remove the top lid 5 from the insulated container 3. In addition, on the outer periphery of the tubular portion 7, convex rib portions 13 having a semicircular cross section are formed at equal pitch in the vertical direction, thereby enhancing the fastening force and flexibility (ease of rolling up) of the tubular portion 7.
[0023] As described above, the elastic damping portion 9 of the top lid 5 is formed from the upper portion (top) of the cylindrical portion 7 toward the inside of the insulated container 3, and has a donut plate shape with a through hole 8 in the center that is slightly larger in diameter than the neck portion 2c of the bottle 2, and the inner surface 14 is formed into a smooth surface that is almost mirror-like. Rubber, particularly silicone rubber, which is the material of the elastic damping portion 9, has excellent self-adhesiveness and flexibility and has high frictional resistance, but the smoother its surface is made, the fewer irregularities there are, and the greater the frictional resistance. Any method can be used to make the inner surface 14 of the elastic damping portion 9 smooth, but one example is to finish the corresponding surface of the mold used for molding to a mirror finish. Of course, the smoother the inner surface 14 of the elastic damping portion 9, the better, but it is not necessary to finish it to an exact mirror finish.
[0024] Next, a method of using the bottle cover 1 of the embodiment will be described. The bottle 2 that can be accommodated by the bottle cover 1 of the embodiment has a body 2a whose thickness is slightly smaller than the inner diameter of the insulated container 3, and a height such that a part of the shoulder 2d as shown in Fig. 4 or the entire shoulder 2d as shown in Fig. 5 protrudes beyond the opening 4 at the upper end of the insulated container 3. However, because the top lid 5 is attached and held in place by fitting the cylindrical part 7 into the insulated container 3 as described above, bottles 2 that are tall enough that the necessary fit margin 11b cannot be secured, that is, bottles 2 that are so tall that the fit of the cylindrical part 7 becomes too shallow when the top lid 5 is attached, are excluded. Furthermore, the bottle 2 may have a shape in which a constriction is provided midway through the body 2a, or a shape in which the shoulder 2d has numerous cut surfaces like diamonds, and may be of any strength, such as a hard material with high rigidity or a soft material that is easily deformed.
[0025] Before the bottle 2 is stored in the bottle cover 1, the top lid 5 is attached to the top of the insulated container 3 as shown in Figures 1 and 2, and this top lid 5 is removed by lifting it up as shown in Figure 3. At this time, it can be removed relatively easily by rolling up the outside of the enlarged diameter portion 10 of the cylindrical portion 7 and lifting it up. Then, a bottle 2 containing a cold beverage such as chilled water in summer, or a bottle 2 containing a hot beverage such as warm tea or coffee in winter, is placed in the insulated container 3. Since the screw cap 2b of the bottle 2 needs to be twisted strongly when opening, it is advisable to open and retighten the cap before placing the bottle in the insulated container 3.
[0026] Next, the top lid 5 is stretched radially and fitted onto the top of the insulated container 3, and the neck 2c of the bottle 2 is caused to protrude outward from the through hole 8, and the top lid 5 is pulled down until the elastic braking portion 9 abuts against the shoulder 2d of the bottle 2 and elastically deforms into a mountain shape, as shown in Figures 4 and 5. In this state, the top lid 5 is attached and held on the top of the insulated container 3 by the fastening force due to the elasticity of the cylindrical part 7 and the frictional force of the rubber, and the elasticity of the elastic damping part 9 applies an appropriate pressure to the shoulder part 2d of the stored bottle 2. Therefore, the stored bottle 2 can be easily and securely fixed inside the insulated container 3, and since the frictional force of the elastic damping part 9 acting on the shoulder part 2d suppresses the rotation of the bottle 2 inside the insulated container 3, the screw cap 2b can be rotated to attach and detach the bottle 2 without having to hold it down with your hand each time. When removing the bottle 2 from the bottle cover 1, the top lid 5 can be removed by lifting up the outer side of the enlarged diameter portion 10 of the cylindrical portion 7.
[0027] Although the present invention has been described above by way of an embodiment, the present invention is not limited to the above embodiment. For example, the above embodiment employs a vacuum double wall as the insulating structure of the insulating container 3, but an insulating material such as polystyrene foam may be provided on the inside of the cup-shaped container. Furthermore, the above embodiment is configured to include all of the elements of claims 1 to 5 as the most preferred embodiment, but the elements of claims 2 to 4 may be selectively adopted as appropriate within the scope that does not impair the effects of the invention.
