Flexible drinking water barrel

Abstract

The invention discloses a flexible drinking water barrel and relates to a container for food drinking water. The supporting force and stability of a barrel body are improved through a triangular `WM`-shaped thin wall structure, the flexibility of the barrel and the times of repeated use of bottled water are determined by the thickness of the barrel wall and the physical and chemical properties of the material, the barrel extends during water filling and automatically shrinks in the water drinking process, air inside and outside the barrel is not exchanged, the difficult problem of secondary pollution during water drinking is radically solved, a barrel opening is combined with a barrel cover through non-return threads, the defect that the barrel opening is difficult to seal through the gland manner under the conditions of large diameter and inconsistent sizes is solved, a support rib is arranged on the exterior of a barrel neck and is supported on a slightly-modified filling equipment diversion rail for filling production, the selection range of the barrel body on plastics is more extensive, the defect that polycarbonate (PC) and polyethylene glycol terephthalate (PET) are easily decomposed to generate harmful substances to the human body under high temperature or direct sunlight, the barrel can be formed more easily through injection, stretching and blow-molding, the barrel can be transported and stored after being compressed, consumers have no need to change a water dispenser, and the water drinking is truly safe and reliable.

Description

Technical field [0001] The invention relates to a food container whose barrel body can be stretched and deformed, that is, a disposable or reusable soft drinking water barrel. Background technique [0002] Existing barrels containing natural water, mineral water, pure water, artificially synthesized water, etc., are mainly made of polycarbonate (abbreviated as PC) and polyethylene terephthalate (abbreviated as PET) plastics. High impact strength, tough texture, wear-resistant, low toxicity, high transparency, can be reused many times, economical in cost, convenient for injection, drawing and blow molding. But they have three disadvantages: First, when the temperature is higher than normal temperature or there is direct light, the bisphenol A in PC precipitates faster in water, and the physical and chemical properties of PET decompose in water faster, and some shells, Delamination, air bubbles, discoloration, etc. Secondly, the base material of the barrel body is hard, not ...

Problems solved by technology

But they have three disadvantages: First, when the temperature is higher than normal temperature or there is direct light, the bisphenol A in PC precipitates faster in water, and the physical and chemical properties of PET decompose in water faster, and some shells, Delamination, bubbles, discoloration, etc.

[0003] Xinxing bagged water realizes one-time use. Although it can make up for the lack of substances harmful to the human body contained in drinking water barrels and the transformation of later-stage polluted water quality, the unit price of the manufactured content (water) is high, and the entire manufacturing method must be changed. Marketing system and consumer drinking habits, waste is obvious
