Abstract
The utility model relates to the technical field of the food package industry, in particular to a subvacuum damp-proof refreshing easy-open lid, comprising an easy-open lid body, wherein the peripheryof an opening cover of the easy-open lid body is provided with a convex edge; and the subvacuum damp-proof refreshing easy-open lid also comprises an elastic film cover which comprises a frame body and an elastic film fixed in the frame body. By using the elasticity of the elastic film, when in use, the elastic film lid is sheathed on the convex edge of the easy-open lid, and then extruded towardthe inside of a container and discharges the air therein, thus leading the pressure in the container to be reduced and forming a subvacuum state; and the external pressure tightens the elastic film,so as to lead the elastic film to form true sealing with the convex edge, thus achieving the effects of preventing damp, keeping refreshing and guaranteeing quality, avoiding secondary pollution of food, guaranteeing the safety of the product and solving the problems in the prior art.
Description
Technical field:
The utility model relates to packaging for foodstuff industry technology field, refers in particular to a kind of sub-vacuum damp-proofing and fresh-keeping easy open lid.
Background technology:
On the packing of food such as milk powder, chickens' extract, except making the mode of being packed in bag, use canned in addition.In the existing canned mode, commonplace employing metal cap body adds the mode of plastic cement lid capping again, promptly at first covers a jar mouth with metal cap body, adds a cover a plastic cement lid again outside whole tank body; The employing easy-open lid that also has adds the mode of plastic cement lid.Although aforesaid way has adopted twice capping, in actual use in case uncap, then can't seal once more certainly, therefore can't accomplish to guarantee the quality, moistureproof, fresh-keeping, make jar interior food in storage, be subjected to repeated pollution on the contrary easily, can't guarantee food security; Especially use the easy-open lid mode, easy-open lid can't restore after opening more, and sealing effectiveness is poorer.In addition, this capping mode is all cumbersome in unlatching and capping, and using to people makes troubles.
The utility model content:
The utility model people provides a kind of sub-vacuum damp-proofing and fresh-keeping easy open lid at the above-mentioned weak point of Food Packaging technology.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of sub-vacuum damp-proofing and fresh-keeping easy open lid, comprise an easy-open lid body, and wherein: the drawing of described easy-open lid body covered the periphery and is provided with a convex edge; It also comprises an elasticity membrane cover, and described elasticity membrane cover comprises framework and the sealing and fixing elastic membrane in framework.
Be provided with radially a protrusion in described framework, and described elastic membrane also extends to this protrusion.
The below of described framework protrusion is provided with the cutting part that the outmost turns seal ring that makes the easy-open lid body passes through.
Described framework is formed by stacking by housing and inside casing, and the edge sealing and fixing of described elastic membrane is at the superimposed place of described housing and inside casing.
After the utility model adopts said structure, utilize the elasticity of elastic membrane, in use the elasticity membrane cover is placed on the convex edge of easy-open lid, in container, push then, with air exhaustion in it, thereby container inner pressure is reduced, form inferior vacuum state, external pressure is tight with elastic membrane, make itself and convex edge form real sealing, therefore reach effect moistureproof, fresh-keeping, that guarantee the quality, avoid food to be subjected to secondary pollution, guarantee product safety, solve prior art problems.
Description of drawings:
Fig. 1 is the exploded drawings of the utility model easy-open lid;
Fig. 2 is the cutaway view of the utility model easy-open lid;
Fig. 3 is the view sub-anatomy of the utility model easy-open lid;
State reference map when Fig. 4 is the utility model use.
The specific embodiment:
Below in conjunction with specific embodiments and the drawings the utility model is further specified.
As shown in Figure 1, the utility model sub-vacuum damp-proofing and fresh-keeping easy open lid comprises an easy-open lid body 1 and an elasticity membrane cover 2, this easy-open lid body 1 is rounded, and its external margin is a seal ring 12, makes easy-open lid body 1 and corresponding tank body or container form sealing by sealing circle 12; The inside of easy-open lid body 1 is provided with to draw cover 10, covers between 10 the periphery and seal ring 12 drawing, and a convex edge 11 is set, and the surface of this convex edge 11 is the arc surfaced of slyness; Described elasticity membrane cover 2 is and cooperates convex edge 11 designs, this elasticity membrane cover 2 comprises framework 21 and the sealing and fixing elastic membrane 22 in framework 21, framework 21 internal diameters are big slightly than convex edge 11 external diameters, what described elastic membrane 22 adopted is elastomeric transparent PVC film, be flat state after installing and fixing, and can have certain degree of tautness.
Particularly, shown in Fig. 2,3, described framework 21 comprises housing 212 and inside casing 213, all adopts hard plastics to make moulding.Wherein the below of housing 212 forms the inner fovea part 2121 that can hold described inside casing 213 just fully, so inside casing 213 can be superimposed with housing 212, and with the edge sealing and fixing of the described elastic membrane 22 superposed surfaces place at the two; On framework 21, be provided with radially a protrusion 211, be that housing 212 and inside casing 213 form radially protrusion 2120,2130 simultaneously, and described elastic membrane 22 also extends to this protrusion 211, and sealing and fixing is at this protrusion 211 place's housings and inside casing superposed surfaces place.In addition, for the seal ring 12 of the framework 21 of in use avoiding elasticity membrane cover 2 and the periphery of easy-open lid body 1 interferes and influences sealing effectiveness, below described framework 21 protrusions 211, be provided with the cutting part 2110 that the outmost turns seal ring 12 that makes easy-open lid body 1 passes through.
As shown in Figure 4, the utility model easy-open lid in use, because covering 10, drawing in the easy-open lid body 1 removed, the framework 21 of described elasticity membrane cover 2 is placed on the convex edge 11 of easy-open lid body 1, then to the middle part of elastic membrane 22 exert pressure (shown in arrow among the figure), thereby with air extrusion and the discharge section air in the container 3, after stopping to exert pressure, because the elastic recoil effect of elastic membrane 22, cause container 3 interior volume of air to increase, so container 3 internal gas pressures can form inferior vacuum state less than barometric pressure, and under the externally atmospheric effect, the edge of elastic membrane 22 and the convex edge 11 of easy-open lid are close to, are formed sealing, therefore the surface design with convex edge 11 becomes slick and sly arc surfaced, can increase elastic membrane 22 and its area of contact, reach better sealing effectiveness; And when needs are opened elasticity membrane cover 2, only need protrusion 21 places at elasticity membrane cover 2, from the below to this elastic membrane applied thrust (shown in arrow among the figure), because these protrusion 21 place's elastic membranes up and down both sides bar pressure are identical, therefore only need a little thrust, can be with elastic membrane jack-up upward, make its edge and convex edge 11 separating contacting states, extraneous air enters in the container 3, and elasticity membrane cover 2 upper and lower sides air pressure equate, are easy to and elasticity membrane cover 2 can be taken out.
In sum, the utility model is simple in structure, and is easy to use, and can keep being in the container pressure vacuum state of negative pressure, realizes real sealing, reaches effect moistureproof, fresh-keeping, that guarantee the quality, more helps the storage of food etc.
