Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 is a sectional schematic diagram of Embodiment 1 of the present disclosure; and

[0017] FIG. 2 is a sectional diagram of a beverage storage device of Embodiment 1 shown in FIG. 1.

DESCRIPTION OF THE EMBODIMENTS

Embodiment 1

[0018] As shown in FIGS. 1 and 2, a beverage vending machine in the present embodiment 1 includes a machine body 5, and a vending mechanism and a beverage storage device which are mounted on the machine body 5, and the vending mechanism is connected to the beverage storage device.

[0019] The beverage storage device includes an inner bag 1 and an external packing container; the inner bag 1 is mounted inside the external packing container; the inner bag 1 has a beverage inlet/outlet pipe 2; the beverage inlet/outlet pipe 2 is mounted on the inner bag 1, and an opening of the beverage inlet/outlet pipe 2 passes through the external packing container and extends out; and the external packing container is provided with a gas inlet/outlet pipe 3 communicating with an external gas source. The inner bag 1 is used to store a beverage, and the external packing container is used for inflating and squeezing the inner bag 1 to deliver the beverage, so that the inner bag 1 just needs to be cleaned after the beverage is emptied, and the cleaning is relatively convenient. Furthermore, the external packing container may be made of other ordinary materials since it is not in direct contact with the beverage, and the production cost is greatly reduced.

[0020] The inner bag 1 is a first plastic bag.

[0021] A material of the first plastic bag is food-grade plastic.

[0022] The food-grade plastic selects polyethylene.

[0023] The external packing container is a plastic barrel 4. In this solution, it is not necessary to use a satisfactory particular material, so that the container is low in cost and relatively light in weight, and can be recycled for beverage storage or other purposes.

[0024] The vending mechanism includes a control device 6, an inflation device 7 and a beverage filling head 8; the control device 6, the inflation device 7 and the beverage filling head 8 are respectively mounted on the machine body; the control device 6 is electrically connected with the inflation device 7; the beverage filling head 8 communicates with the beverage inlet/outlet pipe 2 by means of a beverage output pipe 9; and the inflation device 7 communicates with the gas inlet/outlet pipe 3 by means of a gas pipe 10. The control device 6 controls the inflation device 7 to inflate the external packing container with a certain volume of gas to squeeze the inner bag 1 and cause the inner bag 1 to deliver, by means of the beverage filling head 8, the same volume of beverage, thereby completing filling of the beverage.

Embodiment 2

[0025] The beverage vending machine in the present embodiment differs from Embodiment 1 in that:

[0026] The food-grade plastic is poly-octylene.

[0027] The inner bag 1 is detachably mounted inside the external packing container. Such a design makes the inner bag 1 cleaned more conveniently and quickly.

[0028] The external packing container is a second plastic bag. This solution can greatly reduce the volume of a double-layer beverage storage soft packing container after the beverage is emptied, so that the container is light in weight, and easy to recycle for beverage storage or other purposes.

Embodiment 3

[0029] The beverage vending machine in the present embodiment differs from Embodiment 1 in that:

[0030] The food-grade plastic is polybutylene.

[0031] The inner bag 1 is detachably mounted inside the external packing container. Such a design makes the inner bag 1 cleaned more conveniently and quickly.

[0032] The external packing container is an aluminum barrel. In this solution, it is not necessary to use a satisfactory particular material, so that the container is low in cost and relatively light in weight, and can be recycled for beverage storage or other purposes.

Embodiment 4

[0033] The beverage vending machine in the present embodiment differs from Embodiment 1 in that:

[0034] The food-grade plastic is copolymerized by polyethylene, poly-octylene, and polybutylene.

[0035] While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
