Abstract

The utility model relates to a thermal insulation and fresh-keeping cover with a sealing effect. The thermal insulation and fresh-keeping cover is provided with a body; the body is provided with an open part and a top part; the open part of the body is turned out to form an edge part; the edge part is provided with a sealing ring; one end of the sealing ring is attached to the outer surface of the edge part, which is far away from the top part; the other end of the sealing ring is a flanging in the same direction with the edge part; and the sealing ring is made of silica gel. Compared with a sealing ring used by a common cover, the sealing ring of the thermal insulation and fresh-keeping cover is peripherally additionally provided with the flanging; when the thermal insulation and fresh-keeping cover covers a container such as a dish and the like and a downward pressure is applied to the body, part of air is extruded by deformation of the flanging on the sealing ring, a contact part of the flanging and the container such as the dish and the like is in a sealed state, the thermal insulation and fresh-keeping cover is adsorbed to the dish under the action of the outside atmospheric pressure, and inside air and outside air are insulated in a sealed mode, so that the aims of keeping food fresh and reducing heat loss are fulfilled.

Description

A kind of heat preserving antistaling lid with sealing effectiveness

Technical field

The utility model relates to a kind of sealing thermal insulation fresh-keeping cover of food, takes this heat preserving antistaling lid, can effectively improve the fresh-keeping and heat insulation effect of food, and convenient to use.

Background technology

At present, common food fresh-keeping method is on the plate of food, to cover one deck preservative film being equipped with.In use procedure, need preservative film to be wrapped on whole plate, cutting preservative film then, the not only loaded down with trivial details inconvenience of use procedure, and preservative film also can contact with food, to food, may have a negative impact.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, and a kind of lid is provided, and this lid not only has sealing, insulation, fresh-keeping effect, and use procedure is also simple, quick.

The purpose of this utility model is to adopt following technical scheme to realize:

A kind of heat preserving antistaling lid with sealing effectiveness, this heat preserving antistaling lid has a body, this body has a uncovered portion and a top, it is characterized in that: the uncovered portion of described body outwards routs up an edge portion, in this edge portion, a seal ring is set, in described seal ring one end and described edge portion, away from the outside face laminating at described top, the other end of described seal ring is a flange identical with described edge portion direction; Described seal ring adopts silica gel to make.

Described seal ring is distributed with a plurality of salient points with one end of described edge portion laminating and the surface uniform of relative described flange.

Further, an end periphery of described seal ring and the laminating of described edge portion arranges a groove, and the edge portion of described body is embedded in this groove, and the surface uniform of this groove outside face and relatively described flange is distributed with a plurality of salient points.

On described seal ring, be provided for conveniently taking off the pressure relief device of described heat preserving antistaling lid.

The heat preserving antistaling lid with sealing effectiveness that the utility model provides, compare the seal ring that common lid is used, along seal ring periphery, set up a flange, this heat preserving antistaling is covered on the containers such as plate, when applying a downward pressure to body, by the flange on sealing circle, be out of shape and carried out extruding part air, make the container contact portions such as flange and plate form sealing state, air pressure inside is just less than external atmosphere pressure like this.For the airtight performance of assistant reinforcement heat preserving antistaling lid, the seal ring periphery of this flange is provided with a plurality of salient points relatively.These salient points of seal ring periphery act on flange, and original airtight space that stretches, has increased lid inner and outer air pressure difference.Heat preserving antistaling covers under external atmosphere pressure effect and is adsorbed on plate, makes inside and extraneous air airtight isolated, to reach food fresh-keeping and to reduce the object that heat runs off.

When heat preserving antistaling lid being taken off from the containers such as plate of absorption, preferred scheme is that pressure relief device is set on seal ring, by the pressure relief device on seal ring, make the inside and outside draught head that produces of heat preserving antistaling lid, due to inside and outside draught head, outside air enters in heat preserving antistaling lid from pressure relief device, air pressure inside is returned to identical with external atmosphere pressure value, heat preserving antistaling lid can be taken off from the containers such as plate of absorption.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described:

The present embodiment heat preserving antistaling lid has a body 1 as shown in Figure 1, and this body 1 has a uncovered portion 11 and a top 12, has the handle 14 of the body 1 of conveniently taking on top 12, and on body 1, uncovered portion 11 outwards routs up an edge portion 13.Fig. 2 is the structural representation of seal ring 2, and seal ring 2 adopts silica gel to make.Seal ring 2 has flange 21 and salient point 22.Seal ring 2 is arranged in the edge portion 13 of body 1, outside face away from described top 12 in seal ring 2 one end and edge portion 13 is fitted, the flange 21 of seal ring 2 other ends is identical with edge portion 13 directions, and salient point 22 distributes equably and is arranged on seal ring 2 and one end of described edge portion 13 laminatings and the surface of relative described flange 21.

Be preferably, at seal ring 2 and the periphery of one end of described edge portion 13 laminatings, one groove 23 is set, described seal ring (2) arranges a groove (23), the edge portion 13 of body 1 can be embedded in this groove 23 like this, and a plurality of salient points 22 are evenly distributed on the surface of groove 23 outside faces and relatively described flange 21.

On seal ring 2, pressure relief device is set, can takes off easily heat preserving antistaling lid.In the present embodiment, pressure relief device is the pressure release limit 24 of giving prominence to outside the flange 21 of seal ring 2, only need be with this pressure release limit 24 of handing up, can make air from outside, enter body 1 inside, air pressure inside is returned to identical with external atmosphere pressure value, thereby like a cork heat preserving antistaling lid is taken off from the containers such as plate of absorption.

Fig. 3 is the present embodiment heat preserving antistaling lid structural representation.

Using method is heat preserving antistaling to be covered to body 1 cover and be equipped with on the dish of food, applies downward pressure on body 1, and the distortion that is under pressure of the flange 21 of seal ring 2 bottoms, dwindles the space in body 1, and inner air is run out of.Unclamp after hand, the flange 21 on seal ring 2 makes plate in sealing state.

, after exerting pressure, loose one's grip, the circle of one on seal ring 2 salient point 22 has reverse application force to be evenly applied on flange 21 meanwhile, original seal cavity that stretches, and dish is interior under original amount of air like this, increases confined space volume, and air pressure inside is reduced again.Like this heat preserving antistaling lid airtight played to assistant reinforcement effect.

Because heat preserving antistaling lid air pressure inside is less than external atmosphere pressure, inner airtight isolated with extraneous air, the food in dish has reached fresh-keeping and has reduced heat loss effect.
