Background
As is known, the prefilled syringe is more applied to the fields of vaccine, first aid and the like, and the direct filling of medicine is required to reduce cross contamination and direct injection, so that two functions of medicine packaging and clinical injection are considered. Therefore, the accessories matched with the water-soluble polymer are required to have good chemical and biological properties, usability and sealing protection performance for medicines.
The head needle of the prefilled syringe is required to be protected by a protective cap, the protective cap for the prefilled syringe comprises an inner rubber protective cap and an outer plastic protective cap, the outer part of the rubber protective cap is sleeved with the plastic protective cap, and the rubber protective cap and the plastic protective cap are sleeved together to protect the injection needle. The cap which is sleeved together better realizes the sealing of the needle and prevents the needle from bending and other problems caused by poor stability of simple rubber, and the plastic cap and the rubber cap are required to be pulled out simultaneously when the cap is pulled out from the syringe needle in clinical use because the rubber cap is required to be arranged in the plastic cap, so that the plastic cap and the rubber cap are required to be removed synchronously.
However, the existing plastic protective cap and rubber protective cap are not well combined during assembly, so that the plastic protective cap and rubber protective cap can not be pulled out at the same time.
Disclosure of Invention
The utility model aims to solve the defects in the prior art and provide the prefilled syringe protective cap which has a simple structure, prevents the separation of the rubber protective cap and the plastic protective cap and has high yield.
The technical scheme adopted for solving the technical problems is as follows:
The utility model provides a pre-filling and sealing protection cap for syringe, includes inside rubber protection cap and outside plastics protection cap, and the plastics protection cap is established to the outside cover of rubber protection cap, its characterized in that the upper end outside of rubber protection cap be equipped with annular bulge, the inner wall of plastics protection cap on be equipped with the annular groove that corresponds with annular bulge position, in the annular groove of plastics protection cap was gone into to the protruding card of rubber protection cap annular, the upper end of plastics protection cap was through hot melt towards the crooked joint portion that forms of plastics protection cap inboard below, the joint portion stretches to the bellied top position of rubber protection cap annular.
The upper end face of the rubber protective cap is provided with an annular groove, and the clamping part is clamped through the annular groove.
The annular groove is an inclined groove which is inclined from the outer part of the annular bulge to the lower part of the inner part of the annular bulge, and when the protective cap is pulled out, the clamping part is better inserted into the bottom of the inclined groove, so that the separation of the rubber protective cap and the plastic protective cap is further avoided.
The ventilation holes are formed in the circumferential direction of the plastic protective cap, so that the rubber protective cap can be conveniently inserted.
The clamping part is inclined, and the clamping part inclines towards the lower inner side of the plastic protective cap, and the included angle between the clamping part and the axis of the plastic protective cap is 30-45 degrees.
The inclined plane of the inclined groove and the axis of the rubber protective cap have an included angle of 45-75 degrees, so that the insertion of the clamping part is facilitated.
Due to the adoption of the structure, the utility model has the advantages of simple structure, high yield and the like, and prevents the rubber protective cap from being separated from the plastic protective cap.
Drawings

Fig. 2 is a cross-sectional view of fig. 1.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
As shown in the drawing, the protective cap for the pre-filling and sealing injector comprises an inner rubber protective cap 1 and an outer plastic protective cap 2, wherein the outer side of the rubber protective cap 1 is sleeved with the plastic protective cap 2, and the protective cap is characterized in that an annular bulge 3 is arranged on the outer side of the upper end part of the rubber protective cap 1, an annular groove 4 corresponding to the annular bulge 3 is arranged on the inner wall of the plastic protective cap 2, the annular bulge 3 of the rubber protective cap 1 is clamped into the annular groove 4 of the plastic protective cap 2, the upper end of the plastic protective cap 2 is bent towards the lower side of the inner side of the plastic protective cap 2 through hot melting to form a clamping part 5, and the clamping part 5 extends to the upper position of the annular bulge 3 of the rubber protective cap 1.
Further, an annular groove 6 is arranged on the upper end face of the rubber protective cap 1, and the clamping part 5 is clamped through the annular groove 6.
Further, the annular groove 6 is an inclined groove inclined from the outer part of the annular protrusion 3 to the lower part of the inner part of the annular protrusion 3, and when the helmet is pulled out, the clamping part 5 is better inserted into the bottom of the inclined groove, so that the rubber helmet 1 and the plastic helmet 2 are further prevented from being separated.
Further, the ventilation holes 7 are formed in the circumferential direction of the plastic protective cap, so that the rubber protective cap 1 can be conveniently inserted.
Further, the clamping part 5 is inclined towards the lower inner side of the plastic protective cap 2, and an included angle between the clamping part 5 and the axis of the plastic protective cap 2 is 30-45 degrees.
Further, the inclined plane of the inclined groove and the axis of the rubber protective cap 1 form an included angle of 45-75 degrees, so that the clamping part 5 can be conveniently inserted.
The manufacturing and mounting process of the utility model is that firstly, the plastic protective cap 2 is placed in a fixed mould, the opening part is upward, the rubber protective cap 1 is placed in the plastic protective cap 2 through a turntable, the annular bulge 3 of the rubber protective cap 1 is inserted into the annular groove 4 of the plastic protective cap 2, then the rubber protective cap is rotated to a welding head part, the welding head structure is designed and positioned according to the opening part size of the plastic protective cap 2, the welding head is heated generally by about 120 degrees, the plastic protective cap 2 is pressed by mechanical force, the hot welding is carried out for 10-15 seconds, the upper port part of the plastic protective cap 2 is deformed into the welding head internal structure, the upper end of the plastic protective cap 2 forms a clamping part 5 which is inclined towards the lower inner side, and the rubber protective cap 1 is not influenced, and because the clamping part 5 is clamped at the upper end of the annular bulge 3, the clamping part 5 is clamped with the rubber protective cap 1 at the same time of pulling out the plastic protective cap 2, the phenomenon that the rubber protective cap 1 is simultaneously separated from the plastic protective cap 2 is realized, the rubber protective cap 1 and the rubber protective cap 2 is not separated from the plastic protective cap 2 is realized, the internal structure of the rubber protective cap is the prior art, and the utility model has the advantages of simple structure and high rate of adopting the rubber protective cap 1 and the utility model, and the structure is prevented from separating from the plastic protective cap 2.
