Abstract
The utility model provides a novel-structure butyl rubber stopper for oral liquid, relating to a medical rubber sealing material. The butyl rubber stopper comprises a rubber stopper crown part, a stopper neck and a puncture ring, wherein the arc radius of the rounding of the rubber stopper crown part is R=H-A, H is the thickness of the rubber stopper crown part, and the value of A is 1-1.5 mm. The rounding of the rubber stopper crown part is designed into a great circular arc, which is beneficial to well filling mold during production, improving the percent of pass of the product, deforming the product and discharging air in an aluminum cover when the aluminum cover is installed on the rubber stopper, ensuring the flatness when the rubber stopper is installed, and improving the efficiency for installing the rubber stopper.
Description
Technical field
This utility model relates to the medical grade rubber encapsulant, particularly a kind of new structure oral liquid butyl rubber plug that is used for the sealing of oral liquid.
Background technology
Oral liquid commonly used is now used the plug structure as shown in Figure 2, and its structure is made up of plug bizet, puncture circle and plug neck.Plug is in process of production because the dead angle of bizet top end face mould, rubber mobility is poor during production, and product is prone to the open defect of starved, is difficult for the demoulding, plug can not guarantee that when packing aluminium lid into bizet is close to the aluminium lid inboard, and the production efficiency of aluminium lid dress plug is not high.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of new structure oral liquid butyl rubber plug, and the good mold filling of product in the time of can helping producing improves product percent of pass, also improves dress plug efficient simultaneously.
For solving the problems of the technologies described above, the technical scheme that this utility model adopted is: a kind of new structure oral liquid butyl rubber plug, comprise the plug bizet, and plug neck and puncture circle, the arc radius of plug bizet rounding is R=H-A, the value of A is 1-1.5mm.
The arc radius of described plug bizet rounding is 1-1.5mm.
A kind of new structure oral liquid butyl rubber plug that this utility model provides, by plug bizet rounding being adopted the orthodrome design, the arc radius of plug bizet rounding is R=H-A, and H is the plug crown thickness, and the value of A is 1-1.5mm.Good mold filling in the time of can helping production improves product percent of pass, can help the discharge of air in product distortion and the aluminium lid again when plug is adorned aluminium lid, guarantees that the dress plug is smooth, has also improved dress plug efficient simultaneously.
Description of drawings
Fig. 1 is the front view of this utility model structure;
Fig. 2 is the front view of virgin rubber plug structure.
The specific embodiment
In Fig. 1, a kind of new structure oral liquid butyl rubber plug comprises plug bizet 1, plug neck 3 and puncture circle 2, and the arc radius of plug bizet rounding 4 is R=H-1.2.H is the thickness of plug bizet 1 herein, and the span of A is at 1-1.5mm.
The arc radius of described plug bizet rounding 4 is 1.5-2mm, and many employing arc radius are 1-1.5mm in the our factory.
The big arc design of plug bizet rounding 4 has guaranteed the good flow of sizing material, compares the easier demoulding of product with traditional perpendicular type crown configurations, and product percent of pass improves 3-5%, effectively reduces the product cost of raw material, improves product competitiveness.Before pharmaceutical production is used, must be pre-loaded in the supporting with it aluminium lid because of the oral liquid plug earlier simultaneously, it between plug and the aluminium lid interference fit, plug need bizet is packed in the aluminium lid up, because plug will could guarantee that bizet is close to the aluminium lid inboard through distortion when packing aluminium lid into, and the bizet top curved appearance design discharge of air between aluminium lid and plug bizet will help the product dress and cover the time, thereby realize effectively that fast the dress plug is smooth, improves the production efficiency of aluminium lid dress plug.
Claims (2)
