Abstract
The utility model relates to a kind of airtight lid for container, comprise lid, below lid, be provided with locator card halberd and be socketed with O-ring seal, described lid comprises capping, connecting strap and the card wing, two to four symmetrically or the well-distributed card wing be connected with the neighboring of capping by connecting strap, the lower end of the card wing is provided with card convex; Arrange an elastic force reinforced rib between in the middle part of capping neighboring and the card wing, elastic force reinforced rib is made up of thermoplastic elastomer (TPE) material, and melts bonding with capping and the card wing by heat.Realize the utility model, owing to being provided with elastic force reinforced rib, the peristoma distortion occurred in sintering procedure for supporting earthenware porcelain receptacle has larger comformability, reduces the reject rate caused because requiring the accuracy of earthenware porcelain receptacle body peristoma too high; Again because lid adopts the plastic raw materials once injection moulding that rigidity is higher, card wing rigidity is comparatively large, and energy fastening container body, has failure-free sealing property, and easy to use, is not easy again to damage, effectively can reduces use cost.
Description
Technical field
The utility model relates to a kind of container cover, particularly relates to a kind of airtight lid for container.
Background technology
Do not decompose under acid or alkali environment because earthenware porcelain receptacle has, the advantage of not corrosion, be the container for storing of people's first-selection.But earthenware porcelain receptacle will through forming by a firing, its deformation rate is higher, its peristoma can not resemble metal or plastics make it accurate sizing by mould, so the seal cover cap that earthenware porcelain receptacle mates is generally adopt cover plug to combine, O-ring seal is made to become to seal with the inwall of container body and combine by cover plug, and this cover plug combination easily produces lid and loosens or depart from, failure-free leak tightness can not be guaranteed.Also someone attempts adopting buckle-type at present, namely lid outward flange is provided with many card wings and card convex, but because lid is generally made up of poly-third ethene (PPE) material, the rigidity of this material is higher, in the junction of the card wing and lid in order to realize upwards turning over and buckle downwards, generally all need to design thinner, therefore after lid uses a period of time, easily rupture in this junction, on the other hand, when the distortion of ceramic container for storing oral area is larger, the seal cover cap of this buckle-type cannot adapt to or affect sealing effectiveness.Also someone attempts card wing plasticity good thermoplastic elastomer (TPE) material to make, though have more greatly good comformability to the peristoma distortion that earthenware porcelain receptacle occurs in sintering procedure, but because card wing rigidity is inadequate, when cover cap is on container body and when being buckled downwards by the card wing, card convex is easy to loosen or thread off, impact uses and sealing effectiveness, makes troubles to the use of people.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the utility model provides a kind of deformation rate that can adapt to earthenware porcelain receptacle comparatively large, and has failure-free sealing effectiveness, easy to use and durable airtight lid for container.
The utility model realizes like this, a kind of airtight lid for container, comprise lid, the locator card halberd stretched under being provided with below lid, O-ring seal is socketed with between lid outward flange and locator card halberd, described lid comprises the capping of a firm matter, connecting strap and the card wing, two to four symmetrically or the well-distributed card wing be connected with the neighboring of capping by connecting strap, the lower end of the card wing is provided with card convex; Arrange an elastic force reinforced rib between in the middle part of capping neighboring and the card wing, elastic force reinforced rib is made up of thermoplastic elastomer (TPE) material, and melts bonding with capping and card wing contact portion by heat.
Described elastic force reinforcing rib ring capping neighboring becomes to be connected or is interrupted and arranges.
The thinner thickness of described connecting strap, and adopt can be fused with thermoplastic elastic material and the higher plastic raw materials once injection moulding of rigidity with capping and the card wing, described plastic raw materials is as poly-third ethene (PPE), polyethylene (PE).
The shape of described lid is circular, oval, square or oblong.
Realize the utility model, between in the middle part of capping neighboring and the card wing, an elastic force reinforced rib is set, the peristoma distortion occurred in sintering procedure for supporting earthenware porcelain receptacle has larger comformability, reducing the reject rate caused because requiring the accuracy of earthenware porcelain receptacle body peristoma too high, thus greatly can reduce productive costs; Can be fused with thermoplastic elastic material and the higher plastic raw materials once injection moulding of rigidity because lid adopts again, card wing rigidity is comparatively large, energy fastening container body, there is failure-free sealing property, and easy to use, be not easy again to damage, effectively can reduce use cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present utility model is described further:
A kind of airtight lid for container, comprise square lid 1, the locator card halberd 11 stretched under being provided with below square lid 1, O-ring seal 3 is socketed with between lid 1 outward flange 12 and locator card halberd 11, described lid 1 comprises the capping 13 of a firm matter, connecting strap 14 and the card wing 15, four card wings 15 be symmetric are arranged on the neighboring 17 of capping 13, and the connecting strap 14 that the card wing 15 is less than 0.2mm by thickness is connected with capping neighboring, and the lower end of the card wing 15 is provided with card convex 16; Arrange one deck elastic force reinforced rib 3 between in the middle part of capping neighboring 17 and the card wing 15, elastic force reinforced rib 3 is made up of thermoplastic elastomer (TPE) material, and melts bonding with capping neighboring 17 and the card wing 15 contact portion by heat; 17 one-tenth, neighboring, described elastic force reinforced rib 3 ring cowling face is connected and arranges; Described lid adopts polyethylene (PE) material once injection moulding.
The above is only a kind of embodiment of the present utility model; should be understood that; for those of ordinary skill in the art under the prerequisite not departing from the utility model principle, can also make some conversion and improvement, these all should be included in protection domain of the present utility model.
