Abstract

The utility model discloses a combined cover with circumferentially and uniformly distributed riblet structures at a shoulder part. The combined cover comprises an outer cover with a lower circular shoulder part, wherein the riblet bosses and concave parts are circumferentially and uniformly distributed and formed on the outer side of the shoulder part, and the bosses and the concave parts are arranged at intervals. According to the combined cover with the circumferentially and uniformly distributed riblet structures at the shoulder part, the riblet bosses circumferentially distributed are processed at the ring-shaped shoulder part of the outer cover of the combined cover, as a result, the use amount of raw material for the production is decreased, and further the production cost is lowered. Compared with the conventional combined cover made of the same material and with the same specification and diameter, the combined cover disclosed by the utility model saves the raw material by about 8.3 percent. The combined cover adopts the gear-shaped design characterized in that the bosses and the concave parts are arranged at intervals, accordingly, the accuracy of the inner side circumference of the combined cover is effectively gurantteed, deformation in unlikely to cause, and effect of reinforcement is obtained. Moreover, the beautiful effect of the outer cover is enhanced. The melting sealing effect of the combined cover disclosed by the utility model and a container is good, and a good sealing effect can be achieved.

Description

Shoulder has the composite cover of annular uniform ridge-like structure

Technical field

This utility model belongs to medicinal liquid packaging field, particularly relates to a kind of shoulder and have the composite cover of annular uniform ridge-like structure.

Background technology

Plastic containers dress infusion products is generally made up of two parts, container and medicinal liquid.Container is mainly made up of composite cover and bottle (or bag), has sealing and preserves the functions such as medicinal liquid, easy to use and transhipment.Bottle (or bag) is the packaging material that directly contact medicinal liquid.

Plastic containers dresses infusion products need to be carried out medicine interpolation, be extracted the operations such as medicinal liquid and transfusion by airtight puncture composite cover in the time of clinical use, and therefore conventionally adopting rubber rubber sheet gasket sheet or similarly having suitable elastic material is to answer the perforation relying on after puncture procedure after elastic sealing puncture to ensure the aseptic of infusion products.In the time that the rubber rubber sheet gasket sheet using in composite cover can not directly contact medicinal liquid, the form that need to adopt inner cap+rubber rubber sheet gasket sheet+enclosing cover to inlay assembling is utilized the barrier film of inner cap to intercept rubber rubber sheet gasket sheet and is contacted with medicinal liquid.

The cutaway view of the composite cover of Fig. 1 prior art; Fig. 2 is the perspective view of the composite cover of prior art.As depicted in figs. 1 and 2, composite cover comprises enclosing cover 1 and is connected to rubber sheet gasket 2 and the inner cap 3 in enclosing cover 1, and inner cap 3 is positioned at the below of rubber sheet gasket 2.The overall diameter of the latter half of enclosing cover 1 is greater than the overall diameter of the first half, is called shoulder 4.The periphery of shoulder 4 is level and smooth cylindricality, and the cross section of shoulder 4 is annular, and this structure in use, is vulnerable to extraneous forceful action and deforms, and the inner surface of composite cover and bottleneck or bag mouth can not be fitted tightly, and causes leakage.

Utility model content

This utility model is in order to solve above-mentioned the problems of the prior art, and provides a kind of shoulder to have the composite cover of annular uniform ridge-like structure.

This utility model for addressing this problem taked technical scheme is:

Shoulder of the present utility model has the composite cover of annular uniform ridge-like structure, comprises that the latter half forms the enclosing cover of shoulder, and the outside of shoulder forms annular uniform carinate protuberance and recess, and protuberance and recess are spaced.

The cross section of described recess is curved.

Advantage and the good effect that the utlity model has are:

Shoulder of the present utility model has the composite cover of annular uniform ridge-like structure, and composite cover enclosing cover shoulder is processed into the uniform carinate protuberance of annular, has saved the use amount of manufacturing raw material, has reduced production cost.Adopt composite cover of the present utility model to compare the existing composite cover of same material same specification diameter, about conservation 8.3%.This composite cover enclosing cover, owing to adopting the spaced gear-like design of protuberance and recess, effectively ensures to cover the accuracy of inside circumference, is difficult for deforming, and plays the effect of reinforcement.Meanwhile, also strengthened the aesthetic of enclosing cover.Composite cover of the present utility model and container sealing by fusing are respond well, can play good sealing function.

Detailed description of the invention

Referring to drawings and Examples, this utility model is described in detail.

Fig. 3 is the top view of composite cover of the present utility model; Fig. 4 is the axonometric chart of composite cover of the present utility model.As shown in Figure 3 and Figure 4, shoulder of the present utility model has the composite cover of annular uniform ridge-like structure, comprises enclosing cover and is connected to rubber sheet gasket and the inner cap in enclosing cover, and inner cap is positioned at the below of rubber sheet gasket.The overall diameter of the latter half of enclosing cover is greater than the overall diameter of the first half, is called shoulder 7.The outside of enclosing cover shoulder 7 forms annular uniform protuberance 6 and recess 5.

Protuberance 6 is carinate, and the cross section of recess 5 is curved.Protuberance 6 and recess 5 are spaced, and the cross section of shoulder 7 is gear-like.

Claims

1. a shoulder has the composite cover of annular uniform ridge-like structure, comprise that the latter half forms the enclosing cover of shoulder (7), it is characterized in that: the outside of shoulder (7) forms annular uniform carinate protuberance (6) and recess (5), and protuberance (6) and recess (5) are spaced.
