Description

  The present invention relates to a beverage container cover for preventing a temperature change of a beverage in a beverage container such as a PET bottle.

  Various beverages such as tea, mineral water, juice, and coffee have been sold throughout the year in the state of being filled in beverage containers such as plastic bottles and bottle cans. Beverages in such beverage containers are widely used in homes, offices, sports and leisure because they can be re-opened once opened and can be used in place of water bottles. Among these beverages, beverages in 500 ml size beverage containers are particularly popular because they are not too heavy and are not bulky and are convenient for storage in a bag or the like and for carrying.

  Beverages containing beverage containers as described above are generally sold in a cooled or heated state, but since beverage containers themselves have little heat retention, they are purchased. As time passes, there is a problem that the temperature of the beverage in the beverage container approaches the temperature of the outside air temperature, and the coldness or warmth at the time of purchase is lost. In addition, when the beverage in a beverage container is cooled, condensation occurs on the surface of the container due to the temperature difference from the outside air temperature. There is a problem that the hand to hold slips.

  For this reason, conventionally, various means for preventing the temperature change of the beverage filled in the beverage container as described above have been proposed. For example, in Patent Document 1, a sheet material in which a woven or knitted fabric having elasticity is laminated on both inner and outer surfaces of a closed-cell type rubber sponge layer is formed into a bag shape, and a beverage container such as a plastic bottle is put inside the bag material to exhibit heat insulation. A drink container cover has been proposed. However, the beverage container cover of the cited document 1 has a problem in terms of manufacturing cost due to its complicated structure, and the sheet material is thick, so that the convenience for storing and carrying is low. Patent Document 2 proposes a cylindrical PET bottle cover made of a pile knitted fabric that can absorb dew condensation on the bottle surface. However, although the bottle cover of the cited document 2 can absorb water droplets generated by dew condensation, it is not sufficient in terms of heat retention.

  The first cloth material 13 is preferably a foldable flexible material such as polyester, acrylic, rayon, polypropylene, nylon, etc., but polyester is preferred in terms of cost. The heat insulating material 14 is preferably an aluminum vapor-deposited film in terms of flexibility and foldability. Since the first cloth material 13 and the heat insulating material 14 are both foldable and flexible, the main body 1 can be folded small, which is convenient when stored or carried.

<Aperture>
The opening 2 is formed by a short tubular second cloth material 21 that is shorter than the long tubular covering material 11, and is connected to the upper end 112 of the long tubular covering material 11. As shown in FIG. 3, the short tubular second cloth material 21 has a size that can cover the surface of the shoulder 103 of the beverage container P in a state of being connected to the main body 1. ing.

  In the present embodiment, the short cylindrical second cloth material 21 has a length that is slightly larger than the length of the portion corresponding to the bus bar of the truncated cone in the substantially truncated cone shape constituting the shoulder portion 103 of the beverage container P. And has a diameter slightly larger than the outer diameter of the body portion 102 of the beverage container P. In addition, the size of the short tubular second cloth material 21 can be appropriately set according to the size of the beverage container P accommodated in the beverage container cover 10.

  In the present embodiment, the short tubular second cloth material 21 has a diameter slightly smaller than the diameter of the long tubular covering material 11 constituting the main body 1, As shown in FIG. 1, the lower end 211 of the short cylindrical second cloth material 21 is arranged in a so-called nested state with respect to the upper end 112 of the long cylindrical covering material 11, and the opening 2 is sewn. Has been.

  The short tubular second cloth material 21 is composed of only the second cloth material 22. Thus, since the opening part 2 is formed only by the 2nd cloth material 22, it is easy to ensure a stretching property. However, the opening 2 is not limited to this as long as the stretchability can be ensured. For example, the opening 2 may have a two-layer structure of the second cloth material 22 and the heat insulating material 14 like the covering material 12. .

  The second cloth material 22 is preferably a foldable flexible material such as polyester, acrylic, rayon, polypropylene, and nylon. Polyester is preferred in terms of cost. Since the opening part 2 can be folded small because the 2nd cloth material 22 has the flexibility which can be folded, it is convenient at the time of accommodation or carrying. In addition, when the first cloth material 13, the heat insulating material 14, and the second cloth material 22 are all foldable and flexible, the entire beverage container cover 10 can be folded small. It is more convenient at the time and when carrying.

  As shown in FIG. 2A, the opening 2 has a rubber string 25 attached to the opening edge 23 so that the opening edge 23 can be expanded and contracted. More specifically, the opening 2 includes a piping part 24 formed so as to form an annular shape along the opening edge 23, and a rubber string 25 inserted into the piping part 24. Thus, the opening edge 23 is squeezed and closed in a purse-like manner. Thus, since the elasticity of the opening 2 is provided by the rubber cord 25, the manufacturing is easy and the manufacturing cost can be reduced.

  The diameter of the short cylindrical second cloth material 21 constituting the opening 2 is configured to be larger than the outer diameter of the body portion 102 of the beverage container P as described above, and the rubber string 25 is formed.
