The utility model is characterized in that the internal bladder is consisting of an upper internal bladder and a lower internal bladder and the upper internal bladder and the lower internal bladder are disassemble and removable, and a thin isolating film is provided between the two internal bladders. The utility model has the advantages that the structure is reasonable and the craft is simple; the CO (2) steel cylinder can not be installed, the air and other pollution mediums are kept away from the beer or the drink in the barrel, therefore, the utility model has ideal freshness maintaining effect.

Description

The fresh-keeping bucket of draft beer and soda isolated film formula

The utility model relates to a kind of draft beer and the fresh-keeping bucket of soda isolated film formula.

Usually after draft beer or beverage freshness remaining bucket were opened, it is rotten that the assorted dirt of air and bacterium enters the wine and the beverage that make in the bucket in it, so fresh keeping time is short.People manage to install additional CO for this reason ₂Gas generator or CO ₂Steel cylinder, with entering of replaces air, though effective, make the production use and the cost thereof of fresh-keeping bucket bring problems.

The objective of the invention is to overcome above shortcoming, provide a kind of putting after drinking need not charge into CO ₂And can guarantee the draft beer that do not contact and the fresh-keeping bucket of soda isolated film formula all the time with air.

The utility model is on the basis of existing fresh-keeping bucket, but the circular shape that only its inner bag customized design as interior bucket is become upper and lower inner bag two parts for convenience detach and both edge roll to become tabling, and the nonpoisonous and tasteless isolated film of pressing one betwixt, with the blending of blocking-up and sealing and air, so again with upper and lower inner bag junction with a clip and bolt with further lock ring of three and sealing.

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 1 overall structure scheme drawing of the present utility model.

Fig. 2 connection sealed structural representation of the present utility model.

Fig. 3 is the plan structure figure of Fig. 2.

Wherein 1, connection for bbreather pipe, 2, shell, 3, heat-insulation layer, 4, upper inner-liner, 5, clip, 6, film, 7, bottom inner container, 8, charging and discharging beer valve, 9, nut, 10, screw.

The utility model has charging and discharging beer valve 8, connection for bbreather pipe 1 and shell 2, inner bag and heat-insulation layer therebetween 3, the inner bag that it is characterized in that it is made up of the upper inner-liner 4 that can dismantle and change and bottom inner container 7, thereby and also be provided with the isolated film 6 that also is convenient for changing therebetween, and as Fig. 1, Fig. 2.

Consider for convenience detach and replacing and good airproof performance, above-mentioned upper inner-liner 4, the junction of bottom inner container 7 and isolated film 6 is as Fig. 2, it is the circular-arc of a tabling that the edge of upper inner-liner 4 and bottom inner container 7 can be rolled up, and the edge of isolated film 6 is also circular-arc for what match with it between the two.Be above-mentioned upper inner-liner 4, the edge of bottom inner container 7 and isolated film 6 all is the circular arc edge, and the circular arc that should get the three usually can be same center of circle O.

Further being that reinforcing and leak free need, a unit clamp also can be set in the junction of above-mentioned upper inner-liner 4, bottom inner container 7 and isolated film 6, is that circular-arc clip 5 and nut 9 formed with screw 10 by an end face promptly, as Fig. 3.As long as rotating screw is just strained shell ring gradually, the circular arc edge of upper inner-liner is pressed to isolated film circular arc edge, and presses to bottom inner container circular arc edge together, with connection and the sealing of guaranteeing upper and lower inner bag.Available in case of necessity 2 or certain thickness isolated film 6 or the film 6 that thickens at its edge are to improve intensity and leak tightness.

Obviously the utility model is rational in infrastructure, and technology is simple, need not install CO additional ₂Steel cylinder does not contact beer or beverage in the bucket all the time with other pollution medium with air, have desirable fresh-keeping effect.
