Abstract

The utility model relates to an improved structure of a container for material storage and transportation, in particular to a jar opening sealer comprising a jar opening and a jar plug matched with the jar opening; the jar plug is a semienclosed hollow cylinder with an upper opening; the periphery of the top of the jar plug is also provided with an outer ring edge for position; the jar opening turns outwards with an outer turned edge; an outer cover is covered on the jar plug; the lower edge of the outer cover extends to the lower part of the outer turned edge to be tightly buckled in order that the outer ring edge of the jar plug and the outer turned edge of the jar opening are jointed and sealed. The utility model has larger improvement in either structure or function, and produces better sealing effect; the outer ring cover can be broken with pull, thereby being convenient and anti-fake and achieving the aims of convenience, economy and practicality.

Description

The Jar opening sealer device

(1) technical field

The utility model relates to a kind of structural development that is used for the container of storing material and transportation, especially Jar opening sealer device.

(2) background technology

The sealing common plastics plug of existing metal can jar mouth, this being sealed in the long-term phase storage process because of having gas leakage to produce, causing stores the thing volatilization, if dress chemistry painting industry, make the content skinning, viscosity increases and goes bad, and is a great problem of chemistry painting industry industry packing.

(3) summary of the invention

Main purpose of the present utility model is, overcomes the defective that existing sealing arrangement exists, and a kind of multi-sealed Jar opening sealer device is provided.

The purpose of this utility model is realized by following technical scheme.

A kind of Jar opening sealer device, the jar plug that comprises jar mouth and match, the jar plug is the semiclosed hollow cylinder of upper shed, jar plug top periphery also has outer ring edge for the location, crimping outside the jar mouth has to turning up, one enclosing cover covers on jar beyond the Great Wall, and contracting in the lower edge of this enclosing cover puts in the bottom of outer crimping, and both tight mutually fastenings make jar outer ring edge of filling in fit with the outer crimping of jar mouth and seal.

The purpose of this utility model can also further realize by following technical measures.

Described enclosing cover is made of inner cap and outer ring set, the ring limit is inwardly radially extended in outer ring set perisporium upper end, accommodate inner cap in the outer ring set, the upper end of the two interference fit and inner cap forms an integral body against the ring limit lower surface of outer ring set, and contracting in the lower edge of outer ring set puts in the bottom of outer crimping.

The inboard on the ring limit of described outer ring set also has a pull-tab, and the surface of outer ring set also is provided with to link to each other and run through helping of whole outer ring set with pull-tab splits line.

No matter the utility model structurally or bigger improvement is all arranged on the function, and produced the better seal effect, outer ring set one draws promptly and disconnects, not only convenient but also can be false proof, has reached convenience, economic, practical purpose.

(4) description of drawings

Fig. 1 is a structural representation cut-away view of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1 China and foreign countries ring set.

(5) specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

As shown in the figure, a kind of can mouth sealing device comprises jar mouth 1 and the plastic tank plug 2 that matches.Jar plug 2 is the semiclosed hollow cylinder of upper shed, and jar plug 2 top peripheries also have outer ring edge 21 for the location.Jar mouthful 1 has outer crimping 11, one tin-plate enclosing covers 3 cover on jar fills on 2 to turning up.This enclosing cover 3 is made of inner cap 31 and outer ring set 32, and ring limit 33 is inwardly radially extended in outer ring set 32 perisporiums upper end; Accommodate inner cap 31 in the outer ring set 32, the upper end of the two interference fit and inner cap 31 forms an integral body against ring limit 33 lower surfaces of outer ring set 32; Contracting in the lower edge 34 of outer ring set 32 puts in the bottom of outer crimping 11, and both tight mutually fastenings make the outer crimping 11 applying sealings of outer ring edge 21 with the jar mouth 1 of jar plug 2.The inboard on the ring limit 33 of described outer ring set 32 also has a pull-tab 35, and the surface of outer ring set 32 also is provided with to link to each other and run through helping of whole outer ring set 32 with pull-tab 35 splits line 36.Being provided with pull-tab 22 at the bottom of described jar of plug 2 inner chambers uses so that draw back its diapire.Described jar of plug 2 intracavity sidewalls are provided with and outer crimping 11 cooresponding ring-type protuberances 23, to strengthen jar rigidity of plug 2, better sealing.
