Description

  The present invention relates to a beverage container heat insulator that can retain heat while fixing a beverage container such as a plastic bottle inside.

  In recent years, beverage containers used in the market are excellent in filling and sealing workability in manufacturing, in handling in handling and display in sales, and in convenience in resealing in use. PET bottles made from polyethylene terephthalate are the mainstream. As described above, the PET bottle is not only used as a container for sale, but is also very useful because it can be used in a substantially water bottle when a user drinks the beverage.

  The PET bottle is formed to be thin mainly from the viewpoint of cost reduction and weight reduction. Accordingly, since the beverage filled inside and the outside air easily exchange heat, the PET bottle has no heat retaining property. Conventionally, the contents of PET bottles have been transferred to a water bottle with excellent heat insulation and kept warm, but in recent years when hygiene is important, the need to clean the inner surface of the water bottle is particularly hot. Considering the deterioration and corrosion of the contents at the time, it is not preferable to use such a water bottle.

  As a heat insulator for PET bottles that do not require transfer of the contents, a cloth cover with an aluminum vapor deposition sheet or the like inside is used, and by covering the PET bottle with the cover, an internal beverage, Heat exchange between the outside air and the outside air is suppressed to enable heat insulation. Further, for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2000-82654) discloses a storage container that changes its shape according to the size of a PET bottle and can be kept warm while being stored inside.

JP 2000-82654 A

  However, in the conventional heat retaining device, the contact between the PET bottle and the outside air cannot be effectively blocked, and only a slight heat exchange can be suppressed. In addition, the storage container disclosed in Patent Document 1 can store PET bottles in a predetermined range size, and since the case body constituting the storage container has a structure that can be expanded and contracted, the PET bottle and the storage container The air layer for heat insulation between them does not have a vacuum property, and there is a problem that it cannot have a high heat retaining property.

  Here, paying attention to the structure of the PET bottle storage container, the case body serving as the PET bottle storage portion is configured to be substantially nested and is expanded and contracted to cope with PET bottles in a predetermined range size. For this reason, the heat insulation air layer located between the case body and the plastic bottle communicates with the outside from the contact portion that forms the nested shape of the case body, and the air in the air layer moves to the outside. Therefore, there is still room for improvement from the viewpoint of heat retention.

  Therefore, the present invention was created in view of the above-described problem, and beverage container heat insulation that achieves both the fixation of the beverage container 151 in a predetermined range size inside and the heat insulation of the beverage container 151 fixed inside.

<How to use>

  Hereinafter, the usage method of the beverage container warming tool 1 in this embodiment is demonstrated in detail using FIG.4 and 5. FIG. 4 (a) and 4 (b) are diagrams showing a procedure for inserting and fixing the beverage container 151 to the beverage container warmer 1 in the present embodiment, and FIG. 4 (a) is a beverage in the present embodiment. FIG. 4B is a schematic diagram illustrating a procedure for inserting the beverage container 151 into the hollow layer 21 of the case 3.

  First, the user holds the case 3 and the lid 5 constituting the beverage container warming device 1 in the present embodiment individually, and then the case 3 and the lid 5 as shown in FIG. The screw fitting of the screw fitting portion 31 that becomes the contact point of is released. Specifically, each of the case-side screw 31A included in the case 3 and the lid-side screw 31B included in the lid 5 is rotated with respect to the rotational direction in which the screw engagement is released until the screw is completely released. Rotate. After confirming that the screw fitting of the screw fitting portion 31 has been completely released, the case 3 and the lid 5 are separated, and preferably both are arranged on a substantially horizontal flat surface portion such as a desk or table. .

  Next, as shown in FIG. 4B, the user inserts the beverage container 151 into the hollow layer 21 of the case 3. Specifically, after making the radial center of both the case 3 and the beverage container 151 substantially the same, the beverage container 151 is opened from the opening 11 provided at one end in the longitudinal direction of the case 3. The container bottom 155 is inserted into the hollow layer 21. The beverage container 151 is gradually deeply inserted into the deep portion of the hollow layer 21 of the case 3 while maintaining the state where the radial centers in both sides are substantially the same.

  When the container bottom 155 of the beverage container 151 reaches the elastic member 17 disposed at the deepest portion of the hollow layer 21 of the case 3, the insertion of the beverage container 151 is stopped, and the container upper portion 153 of the beverage container 151 is moved to the top of the lid 5. The case 3 and the lid 5 are fitted while being inserted through the window portion 19 included in the plate 5A. Specifically, the container upper portion 153 of the beverage container 151 is inserted into the window portion 19 from the end portion side provided with the lid-side screw 31B in the lid 5, and the radial direction in both the case 3 and the lid 5 is inserted. The case side screw 31 </ b> A and the lid side screw 31 </ b> B are brought into contact with each other while making the centers substantially the same.

  Subsequently, until the screw fitting of the case side screw 31A included in the case 3 and the lid side screw 31B included in the lid 5 are fixed to each other until the looseness of the screw fitting is almost completely eliminated. Rotate. At this time, if the center in the radial direction of both the case 3 and the lid 5 is shifted, the screw fitting shafts of the case side screw 31A and the lid side screw 31B are shifted, and both screw threads are formed. Will be crushed. For this reason, when fixing screw fitting, it is necessary to rotate it, maintaining the state which made the center of the radial direction in both the case 3 and the lid | cover 5 substantially the same.

  As soon as it can be confirmed that the beverage container 151 does not easily move inside the beverage container warmer 1 of this embodiment or falls off the case 3 together with the lid 5, the beverage container 151 for the beverage container warmer 1 in this embodiment. This completes the insertion and fixing procedure.

  FIGS. 5A and 5B are views for explaining the operational effects of the protrusion 13 and the elastic member 17 on the beverage container 151, and FIG. 5A is the operational effect of the protrusion 13 on the beverage container 151. FIG. 5B is a schematic diagram showing the effect of the elastic member 17 on the beverage container 151. As described above, the protrusions 13 are provided at the same height and at a predetermined interval on the hollow layer 21 side of the case side wall 3 </ b> A, and each protrusion 13 is directed toward the radial center of the case 3. Standing up.

  Even if the beverage container 151 can be filled with substantially the same volume of beverage, the shape in height, width, and the like differs somewhat depending on the manufacturer. For this reason, the clearance between the insertion space for the beverage container 151 inside the beverage container warmer 1 of the present embodiment and the beverage container 151 varies depending on the beverage container 151 used. Originally, if the clearance is not substantially constant, a relatively large size beverage container 151A cannot be inserted into the beverage container warmer 1, and a relatively small size beverage container 151B is desired inside the beverage container 151. Can not be fixed. Therefore, the beverage container warming device 1 of the present embodiment is premised on the use for the beverage container 151 having a capacity of about 500 ml, and is a comparison among the general beverage containers 151 having a capacity of about 500 ml. A space inside the warm container 1 is formed in accordance with the beverage container 151A having a large size.

  In addition, for the beverage container 151B having a relatively small size, although the pressing of the protruding portion 13 and the elastic member 17 is weakened, the protruding portion 13 and the elastic member 17 are filled with clearances in the radial direction and the length direction so as to be fixed as desired. Can be achieved.

<Diameter adjustment>
As shown in FIG. 5 (a), the radial clearance is adjusted by a plurality of protrusions provided on the hollow layer 21 side of the case 3 when a relatively large beverage container 151A is inserted into the hollow layer 21 of the case 3. It is realizable when the part 13 presses the side surface of the beverage container 151A.

  Since the beverage container 151 is mainly formed using polyethylene terephthalate in a thin thickness, it can be subjected to predetermined plastic deformation, and even when the liquid (beverage) is filled inside, the external pressure is applied by applying the external pressure. The shape changes accordingly. That is, when using a beverage container 151A having a relatively large size, the protrusion 13 presses the side surface of the beverage container 151A to be recessed, and the protrusion 13 enters the inside of the beverage container 151A. As a result, a relatively large size beverage container 151 </ b> A can be stored in the hollow layer 21 of the case 3.

  When a beverage container 151B having a relatively small size is inserted into the hollow layer 21 of the case 3, the tips of the plurality of protrusions 13 provided on the hollow layer 21 side of the case 3 come into contact with the side surface of the beverage container 151B. That is, when using a beverage container 151B having a relatively small size, the tip of the protrusion 13 abuts on the side surface of the beverage container 151B and is substantially fixed. As a result, a relatively small size beverage container 151 </ b> B can be stored in the hollow layer 21 of the case 3.

<Adjustment in the length direction>
Subsequently, as shown in FIG. 5B, the adjustment of the clearance in the length direction is the same for both the relatively large size beverage container 151A and the relatively small size beverage container 151B, and the beverage container 151A (151B). Is inserted into the hollow layer 21 of the case 3, the elastic member 17 provided in the hollow layer 21 presses the container bottom 155A (155B) of the beverage container 151A (151B) while generating a repulsive force and pushes it upward. Thus, it is possible to fix between the upper end of the elastic member 17 and the lower end of the top plate 5A.

  As described above, the beverage container warming device 1 of the present embodiment adjusts the clearance between the beverage container 151 such as a plastic bottle in the predetermined size range and the hollow layer 21 individually, and the beverage container 151 is placed in the hollow layer 21. The beverage container 151 inserted into the beverage container heat retaining device 1 can be kept warm by the heat insulating layer 15 provided in the case 3.

  As mentioned above, although one embodiment of the present invention has been described with reference to the drawings, the present invention is not limited to the embodiment and is within the scope of the spirit and teaching of the claims. There are other improvements and modifications. Those skilled in the art will readily understand that all such improvements and modifications are included in the technical scope of the present invention.

  For example, in the above embodiment, the hollow layer 21 inside the case 3 has a plurality of protrusions (ribs) 13 for gripping the beverage container 151 inserted into the hollow layer 21, and the hollow layer of the case side wall 3 </ b> A. A mode has been described in which three or more at the same height are provided at a predetermined interval on the 21 side. The present invention is not limited to this. The number, position, and shape of the protrusions 13 can be set as appropriate as long as the effects of the present invention are not impaired.

  In addition, for example, the protrusion 13 may be a round protrusion, a square protrusion, or a linear protrusion. Further, the protruding portion 13 may be formed by molding a metal material or a resin material that constitutes the case 3, or the protruding portion 13 may be installed as a separate component. As the protrusion 13 as a separate component, for example, various materials such as a metal material, a resin material, and a rubber material such as a hard rubber material can be used.

  The beverage container heat retaining device 1 of the present embodiment is fixed to the beverage container 151 while adjusting the clearance of the hollow layer 21 according to the beverage container 151 such as a plastic bottle in a predetermined size range, and further provided in the case 3. The beverage container 151 can be kept warm by the heat insulating layer 15. The user saves the trouble of transferring the beverage from the beverage container 151 to a water bottle with a heat retaining function, and inserts the beverage container 151 itself into the beverage container warmer 1 without being limited to the size of the beverage container 151. It is possible to keep warm.
