Abstract
A fresh-keeping bucket for beverage comprises an outer casing, an inner casing, and a heat-insulating layer between the outer casing and the inner casing. The utility model is characterized in that the utility model comprises a negative pressure eliminating apparatus, the lower portion of the inner casing is provided with a protruding bench with threads, and an access device is also arranged on the lower portion of the inner casing. The inner casing is provided with a flexible inner container, the lower gate of the inner container is sheathed with an end surface of the protruding bench, and the lower gate of the inner container is provided with a compression ring. The utility model is capable of eliminating the negative pressure and leading to the filling and discharging of the beverage, thereby the beverage will not be polluted, further the structure is compact and simple, the installation is reliable, and the utility model is easy to use and produce.
Description
The utility model relates to a kind of beverage and stores and preservation device, particularly relates to the fresh-keeping bucket of a kind of aseptic beverage.
Beverage pail known today adopts the structure that adds heat-insulation layer between shell and the inner casing, the beverage inner casing of directly packing into, when putting beverage, must enter air and eliminate negative pressure, beverage could flow out, and the stopcock of air by the top enters inner casing and beverage direct contact, airborne bacterium pollutes beverage, the Escherichia coli severe overweight.
The purpose of this utility model provides a kind of beverage freshness remaining bucket, and it can remedy the above-mentioned deficiency of existing apparatus.
A kind of beverage freshness remaining bucket has shell and inner casing, between shell and the inner casing heat-insulation layer is arranged, it is characterized in that having the elimination negative pressure device, the boss of band screw thread is arranged at the inner casing bottom, and the turnover device is housed, the software inner bag is housed in the inner casing, and the inner bag end opening is sleeved on the end face of boss, and the inner bag end opening is equipped with pressure ring.
The utility model not only can have been eliminated negative pressure but also can make beverage irritate into and flow out, and beverage can be not contaminated, and structure is light and handy, simple, it is reliable to install, and was easy to use again and make.
Further specify the utility model below by embodiment and accompanying drawing.
Accompanying drawing 1 is the section-drawing of an embodiment of the utility model.
Accompanying drawing 2 is its air valve structural representation.
The heat-insulation layer 3 that adopts polyurethane foam material to make is arranged between shell 1 and the inner casing 2 in the present embodiment, make beverage can keep certain temperature within a certain period of time.For preventing displacement, and on the upper cover 11 of shell 1 and low head 15, be welded with registration arm 12 and 10 respectively, peg graft with the locating piece on inner casing 2 tops and the locating piece on the fastening elbow 7 respectively and locate at when foaming inner casing 2.Turnover device 9 passes shell 1, and by movable joint nut 6, eyelet bolt 8, fastening elbow 7, connect as one for the boss of one with inner casing 2.Inner bag 4 adopts latex to make, and its size is positioned at the inside of inner casing 2 less than the size of inner casing 2.When irritate beverage, inner bag 4 is stressed and expand; Along with emitting of beverage, inner bag 4 shrinks automatically, particularly can also compress beer foam automatically when splendid attire beer.Being shaped as of inner bag 4 is up-small and down-big, and there is the mouth that dwindles its underpart, and the edge of this mouthful is thicker, forms a circular seal ring, is enclosed within on the end face of inner casing 2 lower boss.When tightening fastening elbow 7, pressure ring 5 is just oppressed the port of inner bag 4, makes its distortion and reaches the leak free purpose.
Elimination negative pressure device in the present embodiment is ventilation flue 13, it is contained between inner casing 2 and the shell 1, and its upper port is connected by nut by the screw of inner casing 2 upper ends, and air valve 14 is equipped with in ventilation flue 13 lower end, it stretches out outside the shell 1, by fastening nut it is fastened on the low head 15.The structure of air valve 14 as shown in Figure 2, wherein valve gap 16 cooperates with valve pocket 22, valve pocket 22 again with valve seat 21 flush fits, back seal bowl 18 is housed on the inclined-plane of valve pocket 22, in the lower end of back seal bowl 18 lower seal bowl 19 is arranged, face is equipped with cylindrical spring 20 within it, under the effect of cylindrical spring 20, make the upper surface of its lower seal bowl 19 and the lower surface closed contact of back seal bowl 18, air tight at ordinary times.Inner face at back seal bowl 18 is equipped with tower spring 17, under the effect of its elastic force, makes the outside of back seal bowl 18 and the interior inclined-plane closed contact of valve pocket 22, because the elastic force of tower spring 17 is greater than the elastic force of cylindrical spring 20, so air tight at ordinary times.Inner bag 4 in the accompanying drawing 1 is made by latex material, its size is far smaller than inner casing 2, so when irritating beverage toward inner bag 4, inner bag 4 can expand, enter air valve 14 by conduit 13 after making the air pressurized in the inner casing 2, i.e. valve gap 16 inner chambers of accompanying drawing 2, the hole by back seal bowl 18 lower ends promotes lower seal bowl 19 moves down cylindrical spring 20, and enter in the chamber of valve pocket 22 and valve seat 21, discharge by the hole of valve seat 21 again.When beverage is emitted, the inner chamber of inner casing 2 can form negative pressure in the accompanying drawing 1, at this moment the barometric pressure of air can be oppressed the hole of air by the valve seat in the accompanying drawing 2 21 and entered inner chamber and promote lower seal bowl 19, lower seal bowl 19 promotes back seal bowl 18 again and moves up, air can enter the conduit 13 of accompanying drawing 1 by the hole of valve gap 16, enters the inner chamber of inner casing 2 again, makes the barometric pressure balance, this process is uninterruptedly being carried out, so beverage can flow out continually.
Because the buffer action of inner bag 4, air can not contact with the beverage in the inner bag 4, has just guaranteed that beverage can not be subjected to the pollution of bacterium in the air.
