The tap 201 is in communication with the liquid passage 40 for pouring the wine in the inner bag 20 into a container such as a cup. The inflating mechanism 202 is communicated with the gas channel 50 and is used for inflating gas between the inner wall of the wine barrel 10 and the outer wall of the inner bag 20, the inflated gas presses wine liquid in the inner bag 20 of the inner bag 20 to be conveyed to the faucet 201 through the liquid channel 40 after passing through the hollow tube 36, and the wine liquid flows into a wine container through the faucet 201.

Examples effects and effects

The beverage barrel that this embodiment provided, the inner bag is sealed through the edge butt fusion by two sheets, has the sack portion that is in the central point of an edge, and the sack portion has two edge portions that are connected with sealed edge respectively, and the lance bottom is equipped with welding portion, and the inner bag is connected with welding portion through the mode of hot melt, and with set up the through-hole at the inner bag side and let the lance pass compare, the processing of sack is simpler, and the connection is also more firm, and the leakproofness is also better.

In addition, the welding part has two end parts extending in opposite directions, each end part has a cross section shape with gradually reduced width, the structure that the middle is thick and the two ends are flat enables the bag mouth to have larger welding area when the welding part is subjected to heat welding, and under the action of the edge part, the bag mouth part has the tendency of folding, and two sheets at the position of the edge part have the tendency of being close to each other, so the welding part with the middle and the two ends being flat is welded in the bag mouth part, therefore, the connection is firmer, and the inner bag is not easy to fall off from a wine spear.

In the beverage barrel provided by the embodiment, the inner bag for containing the wine is arranged in the wine barrel, and the wine is pressed out by filling air between the wine barrel and the inner bag. The wine liquid is contained in the inner bag, the air tightness is better, and after the air is filled, the air is not in direct contact with the wine liquid, so that the wine liquid can be prevented from deteriorating due to air intake.

In addition, the inner bag has certain light-shielding property, and wine can be seriously deteriorated after being contacted with ultraviolet radiation for a long time due to the transparent plastic material of the wine barrel, so that the inner bag with the light-shielding property can prevent the ultraviolet radiation from directly irradiating the wine, and the wine deterioration is greatly delayed.

In the beverage barrel provided by the embodiment, the capacity of the inner bag is 1.7 times of the capacity of the wine barrel, namely, the capacity of the inner bag is larger than the capacity of the wine barrel, so that when the inner bag contains wine, the outer surface of the inner bag is more easily filled with the wine to enable the outer surface of the inner bag to be tightly attached to the inner wall of the wine barrel.

The above embodiments are merely illustrative of specific embodiments of the present invention, and the present invention is not limited to the description of the above embodiments.

In the above embodiments, the inner bag is sealed by edge welding of two sheets, but in other embodiments, the inner bag may be sealed by edge welding of one sheet after folding, and the bag opening is still provided at the center of the welded edge.
