Abstract
The utility model discloses a composite structure of rubber plugs of an infusion bag hard pipe mouth cover and a pipe mouth cover. The composite structure of the rubber plugs of the infusion bag pipe mouth cover and the pipe mouth cover comprises the pipe mouth cover, at least one rubber plug hole is formed in the pipe mouth cover, a rubber plug is inward arranged in each rubber plug hole in an injection molding mode, the rubber plugs and the pipe mouth cover form a whole structure. The composite structure of the rubber plugs of the infusion bag pipe mouth cover and the pipe mouth cover is characterized in that the bottom of each rubber plug hole is provided with an inward protruding arc-shaped protrusion, a puncture hole is arranged in the center of each arc-shaped protrusion, the upper surface and the lower surface of each rubber plug are provided with internal concave arc-shaped grooves, the arc-shaped grooves on the lower surface of each rubber plug are matched with the arc-shaped protrusions. The periphery of each rubber plug is connected with the inner hole wall of each rubber plug hole in a threaded mode so as to increase fastening force. Due to the fact that the arc-shaped protrusions are arranged at the bottom of the rubber plug holes and simultaneously inward protruding arc-shaped protrusions are arranged on the upper surface and the lower surface of each rubber plug, the rubber plugs are provided with a certain outward expansionary force and seal performance between the rubber plugs and the pipe mouth cover is reinforced.
Description
Technical field
This utility model infusion solutions packaging bag technical field, the particularly plug of hard orifice tube for infusion bag lid and mouthful combinative structure of pipe lid.
Background technology
At present, hard orifice tube for infusion bag lid structure as shown in Figure 1, comprise enclosing cover 1, inner cap 2 and be built in inner cap 2 and enclosing cover 1 between plug 3, have easy-to-draw medicated cap 4 on the enclosing cover 1, open easy-to-draw medicated cap 4 and can carry out puncture procedure.In the said structure, enclosing cover 1, plug 3 and inner cap 2 all are individual components, and the three's is fixing fastening by engaging mode or screw thread rotation mode, and the meeting generation is insecure in the anabolic process causes the leakage problem, and too much parts unavoidably cause the raising of production cost.
The utility model content
Technical problem to be solved in the utility model is to provide for the existing hard orifice tube for infusion bag lid existing problem of structure a kind of plug and mouthful combinative structure of pipe lid of hard orifice tube for infusion bag lid, this combinative structure has avoided anabolic process because connecting the not firm leakage problem that causes, can reduce manufacturing procedure, avoid the pollution in the cover combination process, reduce production costs.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
The plug of hard orifice tube for infusion bag lid and mouthful combinative structure of pipe lid, comprise mouthpiece cover, be provided with at least one plug hole on the described mouthpiece cover, in each plug hole, adopt injection molding to be built-in with a plug, plug and mouthpiece cover form overall structure, it is characterized in that, be provided with an arcuation projection protruding upward in the bottom in each plug hole, the center of described arcuation projection offers puncturing hole, the upper and lower surface of described plug has the arcuation groove of indent, and the arcuation groove on the lower surface matches with described arcuation projection; Adopt engage thread to be connected between the inner hole wall in the outer rim of described plug and described plug hole.
The mouth of pipe in described mouthpiece cover is provided with the sealing thin diaphragm.
Owing to adopted technical scheme as above, the plug of hard orifice tube for infusion bag lid of the present utility model is structure as a whole with mouthful combinative structure of pipe lid, in the mouthpiece cover process of injection molding, plug directly is built in the plug hole of mouthpiece cover, form overall structure between plug and the mouthpiece cover, avoided existing enclosing cover and plug in anabolic process because being connected the not firm leakage problem that causes, can reduce manufacturing procedure, avoid the pollution in the anabolic process.This utility model arranges the arcuation projection in the bottom in plug hole, and the arcuation groove of indent is set on the upper and lower surface of plug simultaneously, so that plug has certain outward expansion force, has strengthened the sealing between plug and the mouthpiece cover.
