Abstract
The utility model relates to a water vacuum cover sheet, belonging to the technical field of bottom cover. The water vacuum cover sheet comprises a cover body, wherein the middle part of the cover body is bulged downwards to form an extruding part. The water vacuum cover sheet can be matched with a bottom cover; the downward extruding part can extrude out water full to a bottom mouth together with air in the process of screwing the bottom cover so that the inner part of the bottle body reaches a certain vacuum state; therefore, the quality guarantee period of water soaking food is prolonged.
Description
Technical field
The utility model relates to a kind of water vacuum cover plate, belongs to the technical field of bottle cap aspect.
Background technology
The bottled food of selling on the market especially needs to be immersed in the food in the water, and the bottle cap sealing performance of splendid attire bottle is had certain requirement.If the sealing property of bottle cap is not good, will shorten the shelf-life of food greatly.But the applicant finds that even if the sealing property of bottle cap reaches requirement, the shelf-life of food is not long all the time, and such as the water logging rice cake, its shelf-life had only about 5-7 days.If spent this time, rice cake will begin to turn sour so, even smelly.Scrutinize discovery through the applicant, when on manufacturing line, bottle cap being covered, have air in company with entering in the bottle.Just because of the intervention of air causes the shelf-life not long.
Summary of the invention
In order to address the above problem, the utility model provides a kind of water vacuum cover plate that prolongs the water logging effective period of food quality.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of water vacuum cover plate comprises lid, and the middle part of this lid is protruded the formation press section downwards.
Further preferred as such scheme, described press section is a circular conical surface.
The bottom surface radius of described circular conical surface and the ratio between the height are 6:1 to 4:1, are preferably 5:1.
The utility model water vacuum cover plate can cooperate bottle cap, and in the process of bottle cap screwing, its downward press section can push away the full water to bottleneck together with air, make bottle inside reach certain vacuum state, thereby prolongs the shelf-life of water logging food.Such as the water logging rice cake, after cooperation the utility model water vacuum cover plate, its shelf-life can reach more than 1 month.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model water vacuum cover plate comprises lid 1, and the middle part of this lid 1 is protruded downwards and formed press section 2.This press section 2 is a circular conical surface, and the bottom surface radius of circular conical surface and the ratio between the height be 6:1 to 4:1, is preferably 5:1.
The cooperation of the utility model water vacuum cover plate is placed in the bottle cap, in the process of bottle cap screwing, its downward press section 2 can push away the full water to bottleneck together with air, make bottle inside reach certain vacuum state, thereby prolongs the shelf-life of water logging food.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
