TWO-LAYER FLEXIBLE PACKAGING CONTAINER FOR STORING BEVERAGE

Abstract

A two-layer flexible packaging container for storing a beverage includes an inner bag and an outer packaging container; the inner bag is mounted inside the outer packaging container; the inner bag has a beverage inlet-outlet pipe; the beverage inlet-outlet pipe is mounted on the inner bag, and an opening of the beverage inlet-outlet pipe extends through the outer packaging container and protrudes out; and the outer packaging container is provided with a gas inlet-outlet pipe capable of being in communication with an external gas source. As the inner bag and the outer packaging container are provided, the influence of the gas on the beverage quality can be effectively avoided, and the cleansing of the inner bag is more convenient and quicker; and the outer packaging container can be made of other ordinary materials since it is not in direct contact with the beverage, greatly reducing the production cost.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

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

DESCRIPTION OF THE EMBODIMENTS

Embodiment 1

[0017] As shown in FIG. 1, a two-layer flexible packaging container for storing a beverage in the present embodiment 1 includes an inner bag 1 and an outer packaging container; the inner bag 1 is mounted inside the outer packaging 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 extends through the outer packaging container and protrudes out; and the outer packaging container is provided with a gas inlet-outlet pipe 3 capable of being in communication with an external gas source. The inner bag 1 is used for storing a beverage, and the outer packaging 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 all the beverage is removed, and the cleaning is more convenient. In addition, the outer packaging container can be made of other ordinary materials since it is not in direct contact with the beverage, greatly reducing production cost.

[0018] The inner bag 1 is a first plastic bag.

[0019] A material of the first plastic bag is food-grade plastic.

[0020] The food-grade plastic is polyethylene.

[0021] The outer packaging container is a plastic barrel 4. In this solution, it is not necessary to use a satisfactory particular material, so that the container has low cost and light weight, and can be recycled for beverage storage or other purposes.

Embodiment 2

[0022] The two-layer flexible packaging container for storing a beverage in the present embodiment differs from Embodiment 1 in that:

[0023] The food-grade plastic is poly-octylene.

[0024] The inner bag 1 is detachably mounted inside the outer packaging container. Such a design makes the inner bag 1 cleaned more conveniently and quickly.

[0025] The outer packaging container is a second plastic bag. This solution can greatly reduce the volume of a two-layer flexible packaging container for storing a beverage after all the beverage is removed, so that the container has light weight, and is easily recyclable for beverage storage or other purposes.

Embodiment 3

[0026] The two-layer flexible packaging container for storing a beverage in the present embodiment differs from Embodiment 1 in that:

[0027] The food-grade plastic is polybutylene.

[0028] The inner bag 1 is detachably mounted inside the outer packaging container. Such a design makes the inner bag 1 cleaned more conveniently and quickly.

[0029] The outer packaging container is an aluminum barrel. In this solution, it is not necessary to use a satisfactory particular material, so that the container has low cost and light weight, and can be recycled for beverage storage or other purposes.

Embodiment 4

[0030] The two-layer flexible packaging container for storing a beverage in the present embodiment differs from Embodiment 1 in that:

[0031] The food-grade plastic is copolymerized by polyethylene, poly-octylene, and polybutylene.

[0032] 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.
