CN2714454Y - Fresh keeping container for beer - Google Patents

Abstract

The utility model relates to a fresh keeping container for beer, particularly a device for storing beverage. The fresh keeping container for beer comprises an outer casing and an inner container which is arranged in the outer casing. The utility model is characterized in that the outer casing and the inner container are formed from transparent layers, and a vacuum clamping cavity is arranged between the outer casing and the inner container. The outer casing and the inner container of the utility model are formed from the transparent layers, and thus the beer inventory in the inner container and the condition of a beer discharging piston can be observed at any moment. Because the vacuum cavity is formed between the casing and the inner container, the utility model has good heat-insulating effect and prolongs the fresh keeping time of the beer.

Description

Beer-preserving container

Technical field

The utility model belongs to material reservoir vessel field, is specifically related to a kind of container that is used to store the drinks.

Background technology

On the summer beverage market, beverage often there is fresh-keeping requirement.For this reason, the container that holds beverage also should possess fresh-keeping function.When people drink draft beer, often with beer filling in big stein, this cup is placed on the dining table, so that in cuvette, pour at any time.There is tangible drawback in this stein, promptly the carbon dioxide in the beer be easy to excessive, long-time slightly after, the mouthfeel of beer and nutrition degree just reduce greatly.For a change this situation, the day for announcing is on September 21st, 1988, the patent No. discloses a kind of container that holds beer for the Chinese utility model patent " stein " of " 88203537 ", this container comprises an inner bag, wine outlet is offered on the top of inner bag, be provided with a lid at the top, thereby avoided overflowing of carbon dioxide.When toppling over, the control cock of opening the wine outlet place gets final product pouring.The defective of this stein is, when toppling over beer, need be by means of the air pressure of top in the kettle, otherwise just do not come out.Because the beer in the kettle contacts with air, thereby has influenced the nutrition degree and the fresh keeping property of beer, makes the fresh keeping time of draft beer too short.The applicant has invented a kind of beer-preserving container for this reason, this antistaling container is made up of shell and inner bag, be provided with row's wine piston in the bottom of inner bag, when can beer in this antistaling container, row's wine piston moves down, owing to seal between row wine piston and the container inner wall, thereby along with constantly the pouring into of beer, the air pressure of row's wine piston below constantly increases.During pouring, as long as open wine outlet, the air pressure of row's wine piston below just can push up wine outlet with beer, and beer is poured out in wine outlet.For making beer refreshing, between shell and inner bag, be provided with heat-insulation layer, shell, inner bag and heat-insulation layer are opaque structure.In application, the customer can't learn have or not in the inner bag beer or beer storage what.Moreover people also can't see the piston motion situation in the inner bag, when row's wine piston damages and when poorly sealed, will cause beer to contact with air and influence the fresh-keeping of beer.

The utility model content

The technical matters that the utility model solved is: a kind of beer-preserving container is provided, can observes the beer storage in the container at any time, and the fresh keeping time that can prolong beer.

The technical scheme that its technical matters that solves the utility model adopts is: design a kind of beer-preserving container, comprise shell and the inner bag that is arranged in the shell, it is characterized in that shell and inner bag constitute by hyaline layer, are provided with the vacuum clip chamber between shell and the inner bag.

Blow off valve is set in the utility model, and this blow off valve communicates with the folder chamber; One section of blow off valve can be arranged in the folder chamber.

The beneficial effect that the utility model had is:

(1) because shell and inner bag constitute by hyaline layer, thereby can observe beer storage and row's wine piston situation in the inner bag at any time.

(2) owing to form vacuum chamber between shell and the inner bag, effect of heat insulation is good, has prolonged the fresh keeping time of beer.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the structural representation of another embodiment of the utility model.

1. pull bars among the figure, 2. blow off valve, 3. exhaust piston, 4. gas circuit, 5. tracheae, 6. spring, 7. plug, 8. row's wine mouth, 9. inner bag, 10. shell, 11. row's wine pistons, 12. sealing members, 13. check valves, 14. folder chambeies.

The specific embodiment

Embodiment one

As shown in Figure 1, form the vacuum clip chamber between shell 10 and the inner bag 9, sealing member 12 is set on the shell 10, exhaust piston 3 is set in the sealing member 12, sealing member 12 is connected by the cavity of tracheae 5 with plug 7 tops.Operation pull bar 1 drives exhaust piston 3 and moves, and the air pressure in the tracheae 5 strengthen and promote plug 7 and move down, and after plug 7 moved, row's wine mouth 8 was connected with the cavity of inner bag 9.The air pressure of row's wine piston 11 belows pushes and moves on row's wine piston 11 and beer is discharged in row's wine mouth 8.

Because shell 10 and inner bag 9 constitute by hyaline layer, thereby can observe the beer storage of 9 li of inner bags and the situation of row's wine piston 11 at any time.In use for some time, can enter air in the folder chamber between shell 10 and the inner bag 9, the air that has in the folder chamber can influence the fresh-keeping of beer.For this reason, between sealing member 12 and folder chamber 14 gas circuit 4 is set, an end of gas circuit 4 is connected with sealing member 12, and its connected entrance is positioned at the outside of exhaust piston 3, i.e. that side that does not communicate with tracheae 5; Blow off valve 2 is set on sealing member 12, and blow off valve 2 communicates with the cavity in exhaust piston 3 outsides, and it is extraneous that this blow off valve makes that gas can only flow to from sealing member 12, and can not flow backwards.Check valve 13 is set on gas circuit 4, and this check valve makes gas to flow to sealing member 12 from folder chamber 14, and can not flow backwards.When exhaust piston 3 when the direction of tracheae 5 moves, the cavity in exhaust piston 3 outsides forms negative pressure, the air in the folder chamber 14 can flow to the cavity in exhaust piston 3 outsides, so the air in the folder chamber can be drained.After a period of time, with air extractor with the air extraction in exhaust piston 3 outside cavitys.

Embodiment two

As shown in Figure 2, compare with embodiment one, in the present embodiment blow off valve 2 is directly communicated with folder chamber 14, one section of blow off valve is set directly in the folder chamber 14.

Claims (3)

1. a beer-preserving container comprises shell and the inner bag that is arranged in the shell, it is characterized in that shell and inner bag constitute by hyaline layer, are provided with the vacuum clip chamber between shell and the inner bag.

2. beer-preserving container according to claim 1 is characterized in that also comprising blow off valve, and blow off valve communicates with the folder chamber.

3. beer-preserving container according to claim 2 is characterized in that a section of blow off valve is arranged in the folder chamber.
