Abstract

The utility model relates to a seal cover for the mouth of an open container, particularly for the bottle mouth of an ordinary glass can bottle. A plastic duplicate edge type seal cover composed of an outer side, an upper flat edge, an inner side and a cover bottom effectively prevents the material in the bottle from contacting with the objects with bacterium, and simultaneously, a ring side V-shaped groove and a ring side arc convex bar are arranged to reinforce the sealing performance and ensure the stable connection of the bottle cover and the bottle body. The arrangement of a vent hole and sealing plug can omit the process of pumping the vacuum or inserting a pinhead to vent the air before boiling and disinfecting the can. The utility model can reduce the requirement for the productive condition of the can. Compared with a metal cover, the utility model has the advantages of sufficient raw material, low cost, repeated use and scarce tinplate skin saving.

Description

Plastic seal cover

The utility model relates to a kind of open-top receptacle, particularly seal cover cap of simple glass Cans bottleneck of being used for.

Make can, particularly family manufacture can, reach the purpose of long preservation, must solve the sealing problem of vessel port, make that the material after the sterilization does not go bad because of contacting with container tyre fungus matter in the container.For this reason, all less during general family manufacture can with bottleneck, the ready-made bottle closure of rubber that reuses is arranged and easily 500 milliliters of medical use liquid bottles of leak free be container.But there is following shortcoming in this method: medical use liquid bottle bottleneck is less, and diameter only is 17 millimeters, difficulty rather during the can material in the bottle.To the can retort sterilization time, heat the air of volume increase in addition, must when boiling, in bottle, insert the pumping needle head, after the sterilization syringe needle is extracted from bottle stopper, with medical proof fabric the pin hole stickup is sealed again by bottle stopper for discharging the bottle internal cause.This process has also increased the degree of being hard on of manufacturing process.

If with the simple glass Cans is container, can get rid of the difficulty of can material, but must cover with special-purpose metal at present, and special-purpose gland machinery must be arranged because of bottleneck seals, general family does not possess this condition.Though the present commercially available monolayer plastic system can bottle cap that has, simple in structure because of it, leak tightness can not reach the need of making can.Also be difficult to bottleneck is sealed with additive method.Thereby it is very big to make the difficulty of can at home conditions with the simple glass Cans at present.

The sealing problem of other open-top receptacles such as lunch box and so on vessel port also makes band food working person often rather feel embarrassed for the vegetable soup dirt for another example.

The purpose of this utility model provides a kind of later-model plastics system seal cover cap, it can be so that can be container with the simple glass Cans when making can at home conditions, it is convenient to reach the can material, can stop bottle interior material and the purpose that bottle tyre fungus matter contacts effectively, make the can process process convenient simple and direct and reliable for effect.Also can after changing its profile (not changing its multiple limit structure), seal simultaneously other open-top receptacle mouths.

The purpose of this utility model is to realize with following technical scheme: with the non-toxic polyethylene is raw material, makes by the multiple limit of the integral body type seal cover cap that constitutes at the bottom of outside, last flat limit, inner edge, the lid with injection moulding.Its profile can be made the short garden cylindricality of medial recess or make other shapes (can be made into the rectangle of medial recess as lunch box with seal cover cap) that meet vessel port according to other open-top receptacle mouths according to simple glass Cans bottleneck.The lid principal section is a no following horizontal stroke " recessed " font.Cover body structure is from principal section: go up the suitable character cut in bas-relief in flat limit and go up horizontal line most, its plane is flat on lid topmost position in the form of a ring; Outside quite character cut in bas-relief outside two is perpendicular, and it is conjuncted and vertical with last flat limit with last flat limit outer ring edge; The suitable character cut in bas-relief of inner edge the inside two is perpendicular, and it is conjuncted and vertical with last flat limit with last flat limit interior ring edge; A horizontal stroke in the middle of the suitable character cut in bas-relief in the lid end, it is parallel and conjuncted with the inner edge bottom with last flat limit, is in the lid bottom.Outside, last flat limit, the common formation of inner edge are the multiple limit of reverse U shape.Because outer directly (mouth) that interior straight (mouth) footpath of outside is slightly less than vessel port directly, interior straight (mouth) that outer straight (mouth) footpath of inner edge is slightly larger than vessel port directly reaches upward the plane by three limits of plastoelasticity assurance of plastics itself and vessel port inside and outside wall and is close to and closes and finish sealing.Inner underside in the outside is provided with annular V shape groove, is provided with ring limit arc raised line at the inner edge downside, and they are when strengthening the multiple limit of lid sealing property, and assurance lid and vessel port are held in the mouth close firm mutually.Deflation hole is vertically set on and covers at the end, and the big up and small down taper in hole is in order to the heat expansion air during the material heating disinfection in the amount discharge container.The tapering of cone seal plug equates with the tapering of deflation hole, and it is connected in the outside external lower margin with a plastics tie, is used for material sterilization back and inserts stifled deflation hole, guarantees the leak tightness of deflation hole.

The utility model is because of being manufacturing materials with plastics, and is also reusable, so, sufficient raw simple, with low cost than the crown cap job operation also can be saved sheet tin; Again because of the point of view is to be container with open-top receptacle, particularly glass preserving jar, so solved the problem that material is difficult to can when being container with the medical use liquid bottle at present; Because of having adopted multiple limit type hermetically-sealed construction, with present commercially available monolayer plastic lid relatively, equal to have strengthened sealing surface in addition, also make bottle complications that the passage of inner air and outer air exchange becomes, thereby its sealing property is also just than much better than; Being provided with of deflation hole can be omitted the technological process that must take out the system vacuum before the material heating disinfection in the bottle or must insert medical needle in the bottle, and institute is so that can process technology is comparatively simple.Can also solve the sealing problem of other open-top receptacle mouth.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the front projection figure according to the novel simple glass Cans plastic closure that the utility model proposes.Fig. 2 is its principal section figure.Fig. 3 is its fundamental diagram.

Describe details and principle of work in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3 according to the concrete device that the utility model proposes.

This device comprises by outside (1), goes up the multiple limit of sealing of flat limit (2), inner edge (3) formation and cover the end (8) conjuncted sealed body.(1) is gone up setting and is encircled limit V-shaped groove (4) together in the outside, a ring limit arc raised line (5) is set on the inner edge (3), crosslinked place at the lid end (8) and inner edge (3) has a cylinder (11) to be provided with taper deflation hole (7) at the center of cylinder (11), deflation hole is in the open position among the figure, the outer downside of (1) has a tie (9) in the outside, end at tie (9) has a cone seal plug (6), the tapering of cone seal plug (6) equates with the tapering of taper deflation hole (7), carefully hold connection one a short section back taper to expand end (10) in the long tapering of cone seal plug (6), the butt diameter of end (10) of expanding is slightly larger than the lower port diameter of taper deflation hole (7).

During can process, taper deflation hole (7) is in the open position, with the manual gland of vinyl cover on bottleneck (12).This moment by outside (1), go up the multiple limit of sealing that flat limit (2), inner edge (3) constitute because elasticity of plastics is close to flat limit and bottleneck inwall formation sealed body on bottleneck outer wall, the bottleneck.V-arrangement rib on the bottleneck outside embeds in the bottle cap V-shaped groove (4), and bottle cap arc raised line (5) is against the bottleneck lower inside, and they play auxiliary seal and firm bottle cap and bottle rank altogether and close.After the can sterilization, immediately cone seal plug (6) is filled in the taper deflation hole (7).Because the long tapering of cone seal plug (6) slightly is shorter than the taper hole degree of depth of deflation hole (7), the back taper of its lower end expands end (10) in seal vents (7) end opening, cone seal plug (6) is produced an effect that pulls downwards, make cone seal plug (6) and taper deflation hole (7) to fit tightly automatically and guarantee its seal degree.
