Description

Vacuumed cover structure

The present invention relates to a vacuum-covered cover structure, in particular to a cover body directly provided with an air suction cylinder and a suction piston, and the first cover body provided by the cover body is used for sealing the opening covering a container. Through the upper and lower reciprocating movement of the suction piston, the air remaining in the container is extracted by the suction piston to provide the user, and the air remaining in the container can be immediately extracted to avoid contact with the food in the container. The air is easily oxidized or bacteria are produced to achieve food preservation and preservation in the container.

With the improvement of people's living standards, in daily life, people have been accustomed to various post-processing of foods to increase the taste of food and deepen their nutrition; for example, people use a blender to cut and stir vegetables and fruits. In order to make a rich plant fiber drink, and thus strengthen the food's total diet and all-round nutrition.

Based on this concept, in order to ensure the freshness of processed foods, some manufacturers have developed a slow-grinding food conditioning machine, through which the slow-grinding process allows the fruits and vegetables to minimize the contact with the air and oxidize the process. The original taste and the original color are retained to obtain the freshness and nutrition of the real food; and the theory of the slow-grinding food conditioner is based on food processing. During the process, minimize contact with air to cause oxidation problems.

This is to look at the existing vacuumable containers in the market. Except for the existence of many different shapes and styles, the purpose is to use vacuum to save or preserve foods. In the existing vacuum preservation container on the market, an evacuation pump must be additionally disposed in operation, the suction cylinder corresponds to the suction hole provided in the cover of the vacuum preservation container, and then the air in the vacuum preservation container is selected by the suction cylinder. However, the extra pump is not only difficult to store, but also easy to lose. It is also very inconvenient to use. In addition, the vacuum preservation container requires a large reverse force after vacuuming to open the cover. If the force is not very good, tipping over, spraying, is a common thing, and then lead to the consumer gradually abandoned.

Therefore, under the principle of vacuum as a means and vacuum to achieve food preservation and preservation, providing a vacuum-covered cover structure is the main subject of discussion in this case, and is applied to various types of fresh-keeping Containers or conditioners add to their extensive and progressive practical capabilities.

According to the present invention, the vacuumed cover structure includes a first cover body, a second cover body and a suction piston: the first cover body extends upwardly from the top surface thereof and is provided with an air pump and a pumping cylinder. a first venting hole and a one-way valve are disposed in the range, and the one-way valve is fixedly disposed on the first venting hole, so that the air can only be drawn out from the bottom of the first cover body through the one-way valve to the suction cylinder; the second cover The body is coupled to the first cover body and covers the air suction cylinder, the air suction tube is hidden and located in the second cover body, and the second cover body is provided with a first perforation, the first perforation is relatively located above the air suction cylinder; the air suction piston The pumping piston is disposed in the air pumping cylinder of the first cover body, so that the air suction piston can perform the upper and lower reciprocating motions in the air pumping cylinder, and the top end of the air suction piston extends through the first through hole and extends out of the second cover body. And the pumping piston is pivotally connected with a handle at its top end, and the handle has a mechanism for active transfer.

The technical feature of the present invention is that the first cover body is directly provided with an air suction cylinder, the air suction piston and the one-way valve are disposed in the air suction cylinder, and the second cover body is covered and coupled to the upper side of the first cover body, The second cover body is used for hiding the air suction tube, thereby improving the aesthetics of the whole cover body; in addition, when the first cover body seals over the opening of a container, the suction piston is pulled upward by the handle to keep the container The air flows into the air pump through the one-way valve and is removed, so that the air held in the container can be extracted by the air suction piston by applying force to the air suction piston and reciprocating upward and downward to provide use. The air remaining in the container can be immediately extracted to form a vacuum state, which is convenient for food preservation and fresh-keeping ability, and can completely eliminate the problem that the food in the container is exposed to excessive air, causing oxidation or bacterial growth.

Another technical feature of the present invention is that the first cover body is further provided with a second venting hole outside the air suction cylinder, and the second cover body is combined with a pressure relief plug capable of upper and lower displacement, and is sealed by the pressure relief plug to the second ventilation. Therefore, when the inside of the container is in a vacuum state, the pressure relief plug can be pulled, and the external air can flow into the container from the second vent hole, so that the pressure inside and outside of the container is balanced, and the vacuum state is quickly released, thereby providing use. The first cover can be easily opened.
