Description

Fresh-keeping container cover

Technical field

The utility model relates to a kind of fresh-keeping container cover, especially relates to a kind ofly can irrespectively being applied to container cover on the antistaling container with the type of container or size.

Background technology

As everyone knows, for antistaling container, the size of its container cover must be set to match with the pairing opening of antistaling container.Like this, if the antistaling container of a series of different sizes is arranged, should provide the cell therefor lid respectively, the splendid attire food seepage to prevent means that promptly various containers must use the lid of himself.

But many containers are not equipped with the lid of himself.These containers are adopted the different methods that its splendid attire food leaks that prevents usually.For example, at the restaurant or often use the preservative film of making by vinyl to seal to be equipped with bowl or container in the family as the content of hot soup and so on, so that content can not spill from container.

So, because the preservative film that is used for packing is disposable, so cause the unnecessary wasting of resources.In addition, because preservative film is easy to tear, so must adopt tearing that unnecessary a large amount of preservative films prevent to occur.The packaging film that is contained in the hot soup in the container also can occur covering and tear and be not easy the problem from container packaging film removed easily.

In addition, because packaging film is disposable,,, it causes serious environmental issue owing to being difficult for degraded so will produce a large amount of refuses.

Summary of the invention

The purpose of this utility model is at the problems referred to above, and a kind of easy to use, fresh-keeping container cover that can irrespectively use and can not cause the wasting of resources and environmental issue with the type and the size of various containers is provided.

The purpose of this utility model is achieved in that to have the flexible diaphragm that is used for the contacting container body edges, and is used to set firmly last ring seal member and the following ring seal member that enclose on the limit of flexible diaphragm.

The utility model, last ring seal member has the annular slot that encloses along the limit of flexible diaphragm, and following ring seal member has the slotting circle of the annular of enclosing along the limit of flexible diaphragm, and annular slot and annular are inserted to enclose to constitute fixing clamping structure are enclosed on the limit of flexible diaphragm.

The utility model, the limit of last ring seal member, flexible diaphragm enclose and following ring seal member three between can adopt thermal welding and captive joint, make its fixation, reliable.

The utility model, last ring seal member, down ring seal member the going up of edge that have corresponding flexible diaphragm respectively pressed shoulder, pressed down shoulder, by last pressure shoulder with press down shoulder and constitute clamping structure to the edge of flexible diaphragm.

The utility model, the shoulder that presses down of following ring seal member offers slot, and interlocking has the bottom annular closure member on slot, and the protuberance of bottom annular closure member constitutes the swelling structure that presses down shoulder to following ring seal member.

The utility model, flexible diaphragm have from container body edges extension outward, and this extension constitutes the vacuum release portion to flexible diaphragm, is convenient to discharge vacuum after the vacuum seal adhesive.

The utility model, the extension of the corresponding flexible diaphragm of last ring seal member is provided with hand and holds portion, and this hand is held the vacuum release portion of the corresponding flexible diaphragm of portion, is convenient to the upwards firmly operation of vacuum release portion to flexible diaphragm, discharges vacuum.

The utility model, flexible diaphragm generally are the diaphragms that adopts thermoplastic material to make.

The utility model, thermoplastic material can be that choose in the group formed of polycarbonate, polyethylene, poly-flat dichloroethylene or propylene a kind of makes the non-poisonous material of human body.

The beneficial effects of the utility model are:

1), this fresh-keeping container cover can have and the type of antistaling container or the irrelevant advantage of size;

2), owing to being pull-in on the antistaling container and from antistaling container, its vacuum seal easily takes off, so this fresh-keeping container cover has advantage easy to use;

3), because fresh-keeping container cover does not resemble can only disposablely use the preservative film, but can repeated use, therefore can not cause the wasting of resources or cause environmental problem;

4), after fresh-keeping container cover can directly cover antistaling container, with micro-wave oven antistaling container is heated, the content with in culinary art or the heating antistaling container has and heats advantage easily.

Therefore, the utility model has advantage easy to use, that can irrespectively use and can not cause the wasting of resources and environmental issue with the type and the size of various containers, is applicable to that the sealing of various antistaling containers is fresh-keeping.

Following embodiment accompanying drawings is further described the utility model.
