Bagged water taking device

Abstract

The invention relates to a bagged water taking device. The device comprises a main body, a thorn top and sealing rings, wherein the thorn top is fixed on the top of the main body; the sealing rings are sleeved on the outer side of the main body; the thorn top is a hollow cylinder; and petals or sawteeth with sharp edges are formed at the periphery of the top of the thorn top. The bagged water taking device is convenient to use, is applicable to soft packaging bags made of various materials, has a better sealing effect, and overcomes the defect of the conventional bagged water taking device, and propagation cracks cannot be generated on a packaging film when the bag is pierced.

Description

technical field [0001] The invention relates to a bagged water fetching device. Background technique [0002] With the development of the economy and the improvement of living standards, purchasing drinking water has become one of the most important ways of drinking water for the majority of residents. The existing drinking water can be divided into bottled water and bagged water from the packaging. Among them, bagged water has obvious advantages over bottled water in terms of packaging cost and sanitary conditions. Due to the limitations of devices and packaging bag materials, etc., it has not been widely used. [0003] see figure 1 As shown, the water intake device adopted by the existing bagged water dispenser mainly consists of a main body 1, a thorn top 2 and a sealing ring 3. Wherein, the main body 1 is hollow and has a plurality of water inlets 11 on the upper side, the thorn top 2 is a cone, the sealing ring 3 is a hollow cylinder, the thorn top 2 is fixed on the ...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned existing bagged water intake device can provide the user with a convenient water intake and a bagged water intake device with a sealing effect, it is found that there are still some shortcomings in its structure when it is actually used. The best use effect, but its disadvantages are mainly: the existing food-grade packaging materials such as nylon composite film, etc., have the characteristics of temperature resistance, oxidation resistance, high strength, and poor toughness. "The top of the thorn pierces the film made of these materials. After the film is squeezed, it will produce extended cracks, which cannot expand into a complete circle and cause water leakage.

Therefore, at present, five-layer or seven-layer co-extrusion film is generally used as water bag packaging. The film has good ductility and toughness, but poor oxidation resistance and temperature resistance, and low structural strength. When filling water for disinfection, it is easy to make the water body produce peculiar smell and affect the taste; if it is not disinfected or the disinfection is not thorough, the storage period of the water body (especially when the ambient temperature is high in summer) will be seriously affected, which will directly affect the quality of the bagged water

[0006] It can be seen that the above-mentioned existing bagged water intake device obviously still has inconvenience and defects in structure and use, and even hinders the popularization and use of bagged water, and needs to be further improved urgently.
