Abstract
A kind of plastic container for infusion draw-ring type polypropylene combination cover, it comprises enclosing cover, taper inner cap, draw ring and elastic press.Enclosing cover one end is closed, and one end open, the inner face of closed one end is provided with line of weakness, in the inwall of open at one end, be provided with step surface; Draw ring is connected to enclosing cover and closes on the outer face of one end, and pullling draw ring can tear outer cover rim line of weakness, closes one end form opening with cap seal outside.Taper inner cap is bowl-type, and one end is closed, and one end open, its periphery is provided with radial boss, and taper inner cap is arranged on the step surface in enclosing cover inwall by the radial boss on it.Elastic press is arranged between enclosing cover and taper inner cap, is pressed on the step surface of enclosing cover inwall by taper inner cap by elastic force.When the utility model has the advantage of high temperature sterilize, taper inner cap temperature is far below enclosing cover temperature, and deflection is little, and sealing is guaranteed.And the inner surface of taper inner cap is the conical surface, use procedure herb liquid does not have residual.
Description
Technical field
This utility model relates to a kind of seal bottle cap structure, particularly a kind of plastic container for infusion draw-ring type polypropylene combination cover.
Background technology
Infusion bottle lid is an indispensable part in transfusion bag, and as shown in Figure 6, it comprises lid 1, draw ring 2 and caulking gum 3 to the structure of existing Infusion bottle lid.Lid 1 one end open, one end is closed, and the inner face 11 of closed one end is provided with line of weakness 12, is provided with the annular seal space installed for caulking gum 3 in lid 1; Caulking gum 3 is arranged in annular seal space, and draw ring 2 is connected on the outer face 13 of one end that lid 1 is closed, and pullling draw ring 2 can tear lid 1 along line of weakness 12, closes one end form opening at lid 1.
The Infusion bottle lid of this structure has the following disadvantages: after high temperature sterilize, and lid 1 is easily out of shape, thus and form gap between caulking gum 3, cause liquid leakage, go bad; The inner surface of lid 1 is straight barrel, and is provided with step surface 14, and use procedure herb liquid easily remains in step surface 14 place, affects the accuracy of dosage.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, and provide a kind of plastic container for infusion draw-ring type polypropylene combination cover, affects the problem of sealing after solving the lid distortion of existing Infusion bottle lid, and the problem that use procedure herb liquid is residual.
The technical solution of the utility model is: a kind of plastic container for infusion draw-ring type polypropylene combination cover, it comprises enclosing cover, taper inner cap, draw ring and elastic press.
Enclosing cover one end is closed, and one end open, the inner face of closed one end is provided with line of weakness, in the inwall of open at one end, be provided with step surface; Draw ring is connected to enclosing cover and closes on the outer face of one end, and pullling draw ring can tear outer cover rim line of weakness, closes one end form opening with cap seal outside.Taper inner cap is bowl-type, and one end is closed, and one end open, its periphery is provided with radial boss, and taper inner cap is arranged on the step surface in enclosing cover inwall by the radial boss on it.Elastic press is arranged between enclosing cover and taper inner cap, is pressed on the step surface of enclosing cover inwall by taper inner cap by elastic force.
The further technical scheme of this utility model is: the periphery of taper inner cap is provided with the reinforcement extended vertically.
This utility model further technical scheme is: the step surface in enclosing cover inwall is circular cone.
This utility model further technical scheme is: the central area of the both sides end face of elastic press is equipped with cannelure.
This utility model further technical scheme is: the outer face that taper inner cap closes one end is provided with positioning convex, and the end face of the side that elastic press contacts with taper inner cap is provided with the detent matched with described positioning convex.
This utility model further technical scheme is: described elastic press is quality of rubber materials.
This utility model compared with prior art tool has the following advantages:
1, be provided with taper inner cap in enclosing cover, the inner surface of taper inner cap contacts with medicinal liquid, and during high temperature sterilize, taper inner cap temperature is far below enclosing cover temperature, and deflection is little, and sealing is guaranteed.And the inner surface of taper inner cap is the conical surface, use procedure herb liquid does not have residual.
2, the periphery of taper inner cap is provided with reinforcement, for strengthening the rigidity of taper inner cap, ensures that it is not yielding when high temperature sterilize.
3, the step surface in enclosing cover inwall is circular cone, is convenient to the installation of taper inner cap.
4, the central area of the both sides end face of elastic press is equipped with cannelure, to alleviate the oppressive force of elastic press to enclosing cover and taper inner cap.
5, the outer face that taper inner cap closes one end is provided with positioning convex, and elastic press is provided with the detent matched with described positioning convex, the installation of elastic press can be made to locate more accurate.
Below in conjunction with figure and embodiment, this utility model is further described.
