A square column water cup

Abstract

The invention discloses a square-column water cup. The square-column water cup comprises a cup bottom, a cup body with a water containing cavity and a cup cover. The cup body is in a column type, and the at least upper portion of the water containing cavity is cylindrical with the same inner diameter; the cup cover comprises a body, the four side walls of the body are matched with the inner all of the cylinder, and therefore the cup cover can move up and down in the cylinder, the cup body is made from enhanced PP materials, and a protective layer is also arranged on the inner wall of the cup body. According to a silicone rubber layer with an opening formed in the lower portion, a rubber thin layer with an opening formed in the lower portion and the adsorption effect of the silicone rubber layer with an opening formed in the bottom end, the containing performance of the square-column water cup is better, and the square-column water cup is not prone to slight vibration or touching to further toppling, and has the better using safety; as the protective layer structure is arranged, the effective isolation effect can be achieved, easily-leached ingredients in plastic are prevented from being leached in using and ingested into the human body, and therefore the using safety of the plastic cup is improved.

Description

technical field [0001] The invention relates to a plastic water cup, in particular to a square column type water cup. Background technique [0002] Plastic products have brought great convenience to our life, but on the other hand, its appearance makes people doubt its safety. Plastic cups are disposable containers for beverages and tea. Beverage shops, hot and cold drink shops, milk tea shops, hotels, restaurants and coffee shops generally use the largest amount of disposable plastic cups, providing a variety of take-away drinks in plastic cups and on-site use. [0003] Plastic cups are non-degradable products. Many people throw away the cups after drinking, which also makes this disposable plastic cups the main source of "white pollution". PP plastic cups are commonly used in soy milk bottles, yogurt bottles, juice drink bottles, microwave lunch boxes, hot water cups, etc. With a melting point of 167°C, it is the only plastic box that can be placed in a microwave oven a...

Problems solved by technology

[0005] Although generally food-grade PE, PP and other materials are non-toxic, as a synthetic polymer material, there will be various additives and oligomeric polymers in the plastic. In daily use, For example, soaking in hot water, oil, milk, wine, acid, fruit juice, etc. can leach these substances in plastics, and the longer the use time, the better the leaching effect, so they are ingested into the human body, and after long-term accumulation, they will be affect health

At the same time, in daily use, it is very easy to dump due to small collisions or shaking, and the contents flow out, affecting the safety and efficiency of daily life and work.
