Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a package for winding and covering an object to be packaged, such as a beverage container into which a beverage has been injected, a gas cylinder, or a telephoto lens, and more particularly to a package having a cold insulation / heat insulation and cushioning function.

[0002]

[Prior art]

 Conventionally, it is made of heat-insulating cloth, soft synthetic resin or paper to keep the beer, juice, coffee, liquor, etc. stored in the container cool and warm, and is detachably attached to the outer periphery of the container for use. Insulation sheets have been devised (Shokai 63-23274 and Sho 61-5772). In addition, it is used for gas cylinders, and a removable cover made of a laminated composite sheet of canvas and a foamed sheet has been devised (Japanese Utility Model Publication No. 55-165200).

[0003]

[Problems to be solved by the device]

 However, the conventional heat insulating sheet and the gas cylinder cover described above are, for example, in a cooled can because they are made of a single bonded sheet even if they are formed to have a laminated structure. When it is attached to juice, the heat insulating sheet itself is gradually cooled by the temperature of the juice, and dew condensation occurs on the outer surface of the heat insulating sheet due to the influence of the outside temperature, making it difficult to grip. At the same time, the heat insulating sheet itself becomes dirty, and when it is attached to a heated canned coffee, the heat insulating sheet itself becomes too hot to hold. In addition, since the conventional type is intended to keep cold and warm by wrapping a single heat insulating sheet as described above, the beverage container or gas cylinder wrapped with this sheet is exposed outdoors for the purpose of keeping cold. In that case, there was a drawback that the temperature of the sheet itself was remarkably increased when it was exposed to direct sunlight and the cooling effect could not be exerted at all. Furthermore, because no consideration was given to preventing the contents from falling out, it was not easy to carry.

The present invention has been made in view of the above circumstances, and has sufficient cooling and heat retaining effects and a cushioning effect on a packaged object, and does not cause dew condensation on the outer surface of the object to be packaged. The purpose of the present invention is to provide a package that is free from the inconvenience of falling out.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present inventor has fixed a part of a covering body made of a flexible heat insulating sheet and an outer body made of a flexible thin sheet, and winding them around one or both of them. We devised a package with a retaining part to maintain the state, and as an example of that, by stacking the outer body on the outer surface side of the covering body and fixing one end or both ends in the lateral direction In the non-fastening portion excluding the fastening portion, the coating body and the exterior body are configured to have a two-layer structure that maintains independence, and the coating body is maintained in order to maintain the wound state. Alternatively, the packaging body in which the fixing portions are provided at one end or both ends in the lateral direction of the exterior body or the covering body and the exterior body are continuous in the lateral direction, and the adjacent one end is fixed, In the state where the outer body is wound on the outer side of the A package having a two-layer structure in which the cover and the outer package retain their independence, and at least a fixing portion is provided at the free end of the outer package to maintain the wound state. Devised.

Further, in the above-mentioned package, in order to further improve the effect of keeping cold and heat, an extension portion is provided above the exterior body, and a string insertion hole is formed in a lateral direction of an upper end thereof to form a strap. A package with a structure in which the upper part or the lower part can be closed by inserting it, or by forming an extension part below the exterior body and forming a string insertion hole at the lower end of the extension part and inserting the strap. Invented the body.

Furthermore, in the above-mentioned package, in order to prevent the package from falling out, a package preventing means is provided in the lower part of the cover or the outer package, or a package using a cover having a large friction coefficient at least on the inner surface side is provided. Devised.

[0008]

[Action]

 In the package of the present invention, a cover made of a heat insulating flexible sheet keeps the temperature of the package such as a beverage container containing a beverage and a gas filled gas cylinder or a telephoto lens by blocking heat transfer. It reduces the impact from the outside or the impact when it is dropped. In addition, since the packaging body is secured to the coating body with an exterior body made of a thin sheet at a part thereof, even if the coating body and the exterior body overlap with each other, the coating body and the exterior body are not attached at the non-fastening portion. And 2 have a two-layer structure that maintains their independence, and voids are created between them, so even if the temperature of the packaged item is transmitted to the coating, the heat transmission is blocked by the voids and does not reach the outer packaging. As a result, heat can be prevented from being dissipated and the heat retention effect is improved.In addition, dew condensation occurs on the outer surface of the package due to the temperature difference between the packaged item and the outside air, and the package body becomes hot due to the temperature of the packaged item. Never.

Further, when the package of the present invention is attached to an object to be packaged for the purpose of keeping cold, even if the package is placed in a place exposed to direct sunlight outdoors, as described above, Since there is a gap between them, the exterior body becomes a shade and blocks heat transfer, which prevents the temperature rise of the coating body due to the influence of the outside air temperature, and keeps the temperature of the packaged object constant.

The fastening portion provided on the package has a function of fixing the package to the packaged object after the package is wrapped around the packaged object, and allows the package to be removed freely. To do.

When an extension part is provided on the upper part of the exterior body and a strap is arranged at the upper end of the package, the upper end of the extension part is pulled by pulling the strap, so that the vicinity of the mouth of the packaged object It can cover even the entire body, further improve the cold insulation and heat insulation performance, and the carrying strap can be used to carry the package, and it can be hung in an appropriate place. Furthermore, if an extension is provided at the bottom of the outer package and a strap is placed at the lower end of the package, the package can be attached regardless of the top and bottom of the package, and the bottom of the package can be attached. The extended portion located at is made to have a bottomed bag shape by pulling the extended portion with a strap, and serves to prevent the packaged object from falling off. Moreover, it can be used as a shoulder strap by connecting the ends of the straps provided above and below.

When the falling-out preventing means is provided in the lower part of the covering body or the exterior body of the packaging body, the covering body that has a large friction coefficient on the inner surface side is supported by the falling-out prevention means. In such a case, the frictional force prevents sliding between the object to be packaged and the covering body to prevent slipping off.

Further, since the entire package is made of a flexible material, it can be folded into two or three folds when there is no object to be packaged. Since it is low, it is convenient to carry.

【Example】

 Hereinafter, an embodiment of the package according to the present invention will be described with reference to the drawings, particularly when it is used for a beverage container.

FIGS. 1 to 4 show a first embodiment. In this embodiment, a packaging body is formed by a laminated body in which an outer body is superposed on the outer surface side of a covering body and one end portion of which is fastened. It was done. In the figure, (10) is a package, which is composed of a covering body (11) and an exterior body (12), and the non-fastening portion of both is provided with the coating body (11) and the exterior body (12), respectively. It is formed of a two-layer structure laminate (10 ') that maintains independence and creates a void (α) between the two.

The covering body (11) is made of a substantially rectangular heat-insulating flexible sheet having an extension (11a) formed on the right side in the figure, and has a foaming ratio of 20 times and a polyethylene open cell of 8 mm thickness. Made of foam.

As the heat insulating flexible sheet, in addition to the one shown in this embodiment, in the case of the same material, a material having a thickness of about 6 mm to 10 mm is suitable in terms of the effect of keeping cold, keeping warm, cushioning effect and usability. There is. A sheet having a thickness of 3 mm and twice the length in the lateral direction may be double-wound. As the material, synthetic resin foam such as urethane foam, polyethylene closed cell foam, vinyl chloride resin foam, ethylene vinyl acetate copolymer foam (EVA) and synthetic rubber such as chloroprene rubber may be adopted. In the case of urethane foam, those having a thickness of 10 mm to 25 mm are suitable in terms of the effect of keeping cold and heat, the effect of cushioning and the ease of use, and the foaming density is from 1.5 Kg / m ³ to 4. 0 kg / ^{m 3} up are suitable ones, if below 1.5 Kg / ^{m 3,} the strength becomes brittle by degradation, cold and thermal effect, cushioning effect decreases. Also, 4. If it is 0 kg / m ³ or more, the material cost becomes high and commercialization becomes difficult. For synthetic resin foams such as polyethylene open-cell foams and closed-cell foams, vinyl chloride resin foams, and ethylene-vinyl acetate copolymer foams, a foaming ratio of 15 to 40 times is suitable. When it is less than 15 times, it becomes inflexible and the repulsive force increases so that it cannot be easily wound. When it is more than 40 times, the permanent deformation is not remarkably restored to partial compression. Also, it is easily damaged. Although both open-cell foams and closed-cell foams can be used, open-cell foams are superior in that they have good water absorbency and low cost. It is excellent in that there is a property. Therefore, the covering (11) is formed of a heat insulating flexible sheet made of a laminated material of the ethylene vinyl acetate copolymer foam and another synthetic resin foam or synthetic rubber, and the ethylene vinyl acetate copolymer foam is formed. Optimal ones can be made by arranging so that it is on the side that contacts the beverage container, that is, on the inside. Further, a covering (11) is formed by combining the closed-cell foam and the open-cell foam, for example, the heat insulating flexible sheet made of a laminated material of the closed-cell foam and the open-cell foam to form a continuous body (11). The cell foam may be configured so that it is on the inside, that is, the side that contacts the beverage container, or that the inside of the closed cell foam, that is, the side that contacts the beverage container, has a lateral groove formed therein, and the continuous cell foam is formed in this groove. By forming the covering body (11) with the heat insulating flexible sheet in which the body is embedded, a good covering body rich in water absorption and durability can be formed. The heat-insulating flexible sheet also includes a sheet obtained by laminating a synthetic resin film or a synthetic resin film, or a fibrous material such as a non-woven fabric, a woven fabric or a knitted fabric, on the surface of the synthetic resin foam or the synthetic rubber described above.

The outer body (12) is woven with nylon thread, is made of a thin sheet having a resin coating on the inner surface, and is slightly longer than the covering body (11). The covering body (11) is fixed to the right end extending portion (11a) of the covering body (11) in FIG. 1, and the portions other than the fixing portion are not fixed, resulting in the covering. A gap (α) is formed between the body (11) and the exterior body (12).

The material of the exterior body (12) is not limited to the above-mentioned materials, but may be a cloth such as a woven or knitted fabric made of cotton or the like, or a sheet made of a synthetic resin film such as vinyl chloride. . Also, if aluminum is vapor-deposited on the outer surface, heat is reflected, so the effect of keeping cold and warm is further improved. Further, a pile fabric having a pile formed on the entire outer surface may be used. The resin coating on the inner surface is not always necessary, but if resin coating is applied, the cooling and heat retention properties are improved by eliminating the air permeability of the sheet, and at the same time waterproofness is provided to prevent rainwater and dirty water from the outside. Penetration can be prevented. Alternatively, a synthetic resin film may be attached instead of the resin coating, or a thin foam resin such as urethane may be attached.

(13) is a fastening portion of the covering body (11) and the exterior body (12), the right end portion of the exterior body (12), the extension portion (11a) of the coating body (11) It is fastened to the inside by sandwiching it and sewn from the front and back. As this fastening method, a sticking means such as adhesion or welding may be used, or a joining tool such as a tack may be used for fastening. Furthermore, if two or more of these fastening methods are combined, for example, sticking and tacking, the fastening can be further strengthened. The fastening portion (13) is not limited to the above-mentioned one, and even if the covering body (11) is not provided with the extending portion (11a) and the outer body (12) is folded back at its end and is fastened. Alternatively, the ends of the covering body (11) and the exterior body (12) may be aligned and fixed without folding the exterior body (12).

By doing so, not only is it possible to keep cold and keep warm near the mouth of the beverage container, but also the package (210) becomes a bag with a bottom, so it also functions as a fall-out prevention means. Therefore, there is no risk of the beverage container falling off during transportation. Further, if the straps (217) and (217 ') are connected to each other at their end parts by using an appropriate connecting means, or if a connecting string is connected, they can be carried on the shoulder. . In addition, since the present embodiment is configured vertically symmetrical as described above, it can be used regardless of the top and bottom of the beverage container to be mounted. Further, since the holding part (220) is provided, the beverage can be poured out with one hand, and the holding part (210) can be carried with one hand. Also, it is foldable and convenient to carry. In addition, the cold / heat retaining effect and the buffer effect are the same as those in the first embodiment.

The ones shown in Examples 1 to 3 above are based on the premise of a package for a beverage container, but can be used as a package for a gas cylinder, a telephoto lens or the like with the same configuration. In particular, in the case of storing a plurality of portable gas cylinders having a small capacity, the entire package can be opened, which is convenient for taking out and storing.

[Comparative Example] The following Table 1 shows the results of the cooler effect test conducted by the inventor for the case where each of the samples of three types of the package of the present invention was attached and the case where the package was not attached. Is.

The test method was as follows. Samples A to C according to the present invention were prepared, and those samples were mounted on a plastic bottle infused with 1.5 liters of cold water at 1 ° C. and those not mounted. Then, it was left outdoors during the day and every 30 minutes, the water temperature inside the container as well as the wind speed, weather, temperature and humidity were measured.

Sample A coating: polyethylene open-cell foam 8 mm thick, expansion ratio 15 times Exterior body: nylon thin sheet, with upper extension part Sample B coating: polyethylene open-cell foam 10 mm thickness, expansion ratio 15 times Outer body: Nylon thin sheet, no upper extension portion Sample C Cover: EVA closed cell foam 8 mm thick, expansion ratio 15 times Outer body: Nylon thin sheet, no upper extension portion

[Table 1] Generally, when the water temperature rises above 22 ° C, it becomes hot and difficult to drink. When the above test results were evaluated with this 22 ° C. as the limit, those without the package reached 22 ° C. in about 1 hour and 10 minutes, but Sample C had about 3 hours and 30 minutes, and Sample B had about 3 hours and 30 minutes. It was confirmed that Sample A had a sufficient cooling effect for about 4 hours and about 5 hours.

[Effect of device]

 As described above in detail, the packaging body according to the present inventor has a covering body made of a flexible heat insulating sheet and an outer body made of a flexible thin sheet, which are partially fixed to each other. Since the outer body is superposed on the outer surface side and one end or both ends in the lateral direction of the outer body are fixed to each other, the covering body and the outer body are independent from each other in the non-fastening portion excluding the fastening portion. It is constructed so as to have a two-layer structure in which it is held, or the covering and the outer body are laterally continuous and the adjacent one end is fixed, so that the winding starts from the covering side and With the outer body wound around the outside, the covering body and the outer body have a two-layer structure in which the independence of each of the outer body and the outer body is maintained. The heat insulating flexible sheet The heat transfer is cut off by the cover, which keeps the temperature of the packaged object such as beverage in the beverage container, and the outer casing made of thin sheet is freely separated from the cover, and a gap is created between them. Therefore, even if the temperature of the packaged object is transmitted to the covering body, the heat transfer is blocked by the space and does not affect the exterior body. Condensation does not occur due to the difference, and the exterior body does not heat up.

Even when the package is attached to an article to be packaged such as a beverage container and placed in the direct sunlight of the outdoors, a void is generated between the exterior body and the cover body as described above. Since the exterior body becomes a sunshade and blocks heat transfer, the temperature rise of the covering body due to the influence of the outside temperature is prevented, and the proper temperature of the packaged object is maintained for a long time.

The retaining portion provided on the package body winds the package body around an article to be packaged such as a beverage container, then fixes the package body to the article to be packaged and allows the package body to be detached freely. .

In the case where the above-mentioned package has a structure in which an extension portion is provided above the exterior body and a string insertion hole is formed in a lateral direction of an upper end thereof to allow a strap to be inserted, By pulling on the strap, the upper end of the extended part is pulled down, so it is possible to cover even the entire area around the mouth of the packaged object such as a beverage container, further improving the cold insulation and heat retention performance, and using the strap to package the bag. It is extremely easy to carry and can be hung in a suitable place.

Further, when an extension portion is provided below the exterior body and a strap insertion hole is formed at the lower end of the extension portion in the lateral direction to insert the strap, regardless of the top and bottom of the packaged object such as a beverage container. The extension can be attached to the package, and the extended portion located at the bottom of the packaged object is squeezed with a strap to make the package have a bottomed bag shape. To prevent slipping off. Moreover, it can be used as a shoulder strap by connecting the ends of the straps provided above and below.

Furthermore, in the above-mentioned package, in the case where a drop-out preventing means is provided in the lower part of the covering body or the exterior body, the drop-out preventing means supports the object to be packed such as a beverage container, or at least the inner surface thereof. When a coated body with a large side friction coefficient is used, the frictional force prevents sliding between the packaged article and the coated article to prevent the packaged article from falling off.

Further, since the packaging body is composed of the flexible heat insulating sheet and the flexible thin sheet, it can be folded when it is not needed and can be easily made into a compact state, which is convenient for carrying.
