Problems solved by technology

In order to avoid waste, perishable liquids are generally packaged in small-capacity plastic bottles, which are generally only suitable for one-time use
This not only increases the packaging cost and wastes packaging resources, but also is not conducive to resource recovery and easily causes environmental pollution
[0004] Second, although plastic bags do not interfere with air during use, they are also easy to breed bacteria because they are difficult to seal
Therefore, liquids that are easy to deteriorate are generally only packed in small-capacity plastic bags, which are generally only suitable for one-time use.

specific Embodiment 1

[0013] like figure 1 As shown, (1) represents a pouch made of flexible plastic material with sterile liquid inside, (2) represents a tube core made of hard plastic, the tube core (2) and the capsule Bag (1) air-tight fixed connection. The figure shows that the tube core (2) is plastic-sealed on one side of the pouch (1), and the inner cavity of the tube core and the inner cavity of the pouch are communicated with each other. Other common fixed connection methods can also be used or the tube core and the pouch are integrally formed, which are all existing technologies and can be achieved by technical personnel in the industry without creative work. The top end of the tube core (2) is closed, and a through hole (22) is opened on the side wall thereof. (3) represents a sleeve made of elastic rubber material, one end of which is open, and the other end is closed to open an incision (33). closure. The sleeve (3) is tightly sleeved on the outer surface of the tube core (2) and c...

Abstract

The invention provides a self-closed type outlet device of a liquid container and aims at providing a liquid packaging scheme. By means of the liquid packaging scheme, the liquid container is proper in volume, capable of being used many times without adding a bacteriostatic agent after being unsealed, convenient to use and low in cost. According to the principle, the self-closed type outlet device is arranged on the conventional liquid container, the device can be automatically opened during liquid discharging and can be automatically closed after liquid discharging is finished, and therefore air or bacteria are prevented from invading into the liquid container. Furthermore, an anti-bacteria layer can be arranged at the gap position into which the bacteria are prone to invading, accordingly the anti-bacteria capability of the device is further improved, and the purpose that bacteria cannot be bred when the liquid container is used many times is achieved.

Description

technical field [0001] The invention relates to the field of liquid containers, and in particular to the field of liquid packaging containers that are perishable and unsuitable for adding bacteriostatic agents. Background technique [0002] Currently, plastic bottles and bags are the most widely used liquid packaging containers. Common drinking products, such as milk and juice, are generally packaged in disposable plastic bags; common medical supplies, such as eye drops and saline, are generally packaged in disposable plastic bottles. The following problems exist: [0003] First, when using plastic bottles to squeeze, pour or pump liquids, air must be inserted to fill the lost volume of liquid. The liquid left in the bottle is easy to be oxidized and deteriorated by the air, and it is easy to breed bacteria. If no antibacterial agent is added, it must be used up on the same day; even if antibacterial agent is added, it must be used up as soon as possible after opening. I...
