Description

A kind of vacuum round tank

technical field

The utility model relates to the field of daily necessities, in particular to a vacuum-pumped round can.

Background technique

With the development of society and the advancement of science and technology, people have more and higher requirements for food preservation or anti-oxidation of daily necessities. In order to keep the food in the container fresh, the air in the container is usually sucked out. Make the container in a vacuum state, so as to realize the freshness of the food in it. At the same time, in order to prevent the oxidation of the article and the loss of moisture in the article, it is usually necessary to isolate the article from the air and keep it in a vacuum state.

In the prior art, the fresh-keeping lunch box is generally a sealed can, which relies on sealing the box body to block the air inside and outside the box, so as to achieve the purpose of keeping fresh and isolating the air. However, in such a fresh-keeping lunch box, although the air inside and outside the box does not communicate with each other, there will be air in the box, and the oxygen in the air will oxidize the food in the box, thereby affecting the freshness of the food, and the freshness time is limited.

There is a kind of vacuum fresh-keeping lunch box. When using it, it needs to be equipped with vacuum equipment to complete the vacuuming step. The vacuum equipment brings a lot of inconvenience in use and carrying, and when the vacuum equipment is damaged, the fresh-keeping lunch box cannot be used. The vacuumizing step is completed, so that the fresh-keeping lunch box cannot play the role of fresh-keeping.

The applicant submitted a patent application number "201320556820.X" to the National Patent Office on September 10, 2013, and the utility model patent of the invention titled "a manual vacuum fresh-keeping lunch box". It does not need external supporting vacuuming equipment to complete the vacuuming step. However, this technology still has certain defects. During the manual vacuuming process, there is no clear indication of the vacuum state in the box, resulting in manual vacuuming. The specific completion time cannot be judged, and if the judgment is wrong, the fresh-keeping quality in the box body will be affected.
