Abstract

The utility model relates to an inner liner for a heat insulating cask for beer and beverage. The utility model is composed of a liner body, a liner opening, and a liner mouth, wherein, the liner body is composed of an inner layer, an outer layer, and a vacuum layer between the inner layer and the outer layer; the inner layer and the outer layer are connected to the liner opening; the inner liner is made of stainless steel, other kinds of metal, or other kinds of nonmetal. Through the utility model, the heat insulating cask for beer and beverage can have a multilayer structure that comprises a housing, a foaming layer, the outer layer of the inner liner, the vacuum layer, and the inner layer of the inner liner. The utility model has the advantages of outstanding heat insulating effect, extended heat insulating time, and reduced loss, and 30 % to 300 % of the heat insulating time is extended. The utility model which is favorable to popularizing and using the heat insulating cask in the south can be used in the heat insulating cask for beer and beverage.

Description

The inner bag of beer, beverage heat-preserving container

The utility model relates to the beverage freshness remaining storage, the beer of the insulation storing that is used for drinks, soda, fruit juice, sour milk, soya-bean milk etc. of more clearly saying so, the inner bag of beverage heat-preserving container.

Beer up to now, beverage heat-preserving container are mostly constituted by inner bag, shell and between the foamed plastic layer between the two.Its inner bag is then by plastics individual layer blow-molded plastics such as polyethylene or polypropylene.The patent No. be 88202411.6 and the Chinese utility model patent of 89203310.x be not always the case.Mainly by the insulation of foamed plastic layers such as polyurethane, single layer inner bag does not have insulation effect to these heat-insulation pressure keeping buckets.Therefore, its soak is short, has only four, five days at the most even two, three days.Like this, do not satisfy the needs of beer, the longer storage of beverage, fortune, sales process, cause the rotten of beer, beverage, cause damage.At southern area,, lose bigger because temperature is higher.Make this bucket produce difficulty in southern popularization.

The purpose of this utility model, be to overcome above-mentioned shortcoming and defect, provide a kind of soak of bucket that can make to prolong greatly, the quality and the freshness that can longer-term keep beer, beverage, thereby can reduce loss greatly, make it beer that also can very fast popularization at southern area, the inner bag of beverage heat-preserving container.

In order to achieve the above object, the utility model is made of with the courage mouth that is connected courage body bottom the courage mouth on courage body and courage body top, the courage body then by internal layer, be enclosed within the outer of internal layer outside and formed between the vacuum layer between the two, internal layer is connected at courage mouth place with skin.This is actually a kind of structure of Dewar flask.Because the existence of the vacuum layer between the inside and outside layer has reduced conduction, the convection current of heat greatly, thereby has strengthened its heat insulation effect greatly, has prolonged its soak greatly.Such inner bag cooperates with plastic casing and the foamed plastic layer between the two again and has just produced very outstanding heat insulation effect, has obtained obvious improvement.

The courage mouth outside can have outside thread, so that install, has the bung or the bucket valve of negative thread.The courage mouth can be not threaded yet, and this moment, bung or bucket valve can be installed on the mouth of shell, and on the outer with rubber pad left and right sides courage mouth.The courage mouth can be that opening is connected the tubulose that its outer end has connecting thread at internal layer and with skin, so that wine tap or valve are installed out.Courage mouth outer end can be not threaded yet, can tighten or be bonded in courage mouth outer end when wine tap or valve are installed out.Also may adopt other known structure.

Inner bag can be made by non-metal, also can be made by metals such as corrosion-resistant steel, aluminum alloys.Metallic inner bag intensity height is convenient to high-temperature water and is cleaned, sterilizes, and effect is fine.When particularly making, can strengthen inside, the outer outside width of cloth of internal layer of heat and penetrate, further reduce thermal loss, further prolong soak with bright stainless steel.

Task of the present utility model comes to this and finishes.

The utility model has prolonged the soak of beer, beverage heat-preserving container greatly, can keep the quality and the freshness of beer, beverage for a long time, thereby can reduce loss greatly, makes the heat-preserving container at southern area also can very fast popularization.Compare with the like product in past, soak of the present utility model has prolonged 30-200%, and it can be widely used in beer, the beverage heat-preserving container.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further narration.

Fig. 1 is the structural representation of present embodiment 1.

Fig. 2 is the structural representation of inner bag in the past.

Shown in Figure 1, the courage body of present embodiment 1 by internal layer 1, be enclosed within the outer skin 2 of internal layer 1 and the vacuum layer 3 between the person is formed.Internal layer 1 is connected at courage mouth 4 places with outer 2.Courage mouth 4 outsides have outside thread 5.Courage mouth 6 openings are connected sealing at internal layer 1 and with outer 2, and its outer end has connecting thread 7 so that the wine tap to be installed out, is tubulose.Present embodiment is made by bright stainless steel, and convection current, conduction and the inside and outside width of cloth that can significantly reduce heat are penetrated, and prolongs soak 150%.Can be widely used in beer, beverage insulation guarantor in bucket.

Shown in Figure 2, the inner bag in past is made of courage body 8, courage mouth 4 and courage mouth 6, is individual layer.It is contained in the shell 9, and the centre is a foamed plastic layer 10, and heat insulation effect is poor.
