Description

Composite cover and have the container of this composite cover

Technical field

This utility model relates to a kind of composite cover and has the container of this composite cover.

Background technology

The composite cover of prior art and plastics package with this composite cover are as shown in Figure 1, composite cover is made up of enclosing cover 51, plug 52 and inner cap 53, at first enclosing cover sealing 511 is removed during use, expose plug 52 so that use for the syringe puncture, in use, the puncture needle of transfusion device is held tightly to guarantee that transfusion device can not break away from infusion vessel when infusing by plug 52.

The inventor finds that there are the following problems at least in the prior art: because the particularity of infusion products, enclosing cover sealing 511 before use can not be damaged, draw ring can not be broken in use, but the part at enclosing cover 51 centers must be pulled open with plug 52 in exposing, satisfying above-mentioned requirements makes very high to the material requirements of enclosing cover 51, promptly should satisfy the welding fusing point the same, require the enclosing cover 51 back draw rings that are shaped that stronger tenacious and persistent will is arranged simultaneously again with inner cap 53.The material price that satisfies this requirement is three times of inner cap 53 material prices, simultaneously owing to require sealing 511 must stand intact before use, and be easy to pull open when using, it is very high that this requires the mould and die accuracy of shaping enclosing cover 51, costing an arm and a leg of mould, based on this 2 point, make composite cover cost as shown in Figure 1 very high.
