Disclosure of Invention
The utility model aims to solve the technical problems that a rubber plug in the background art is easy to enter a bottle body, more scraps fall and complicated production and assembly procedures are solved.
In order to solve the technical problems, the utility model adopts the following technical scheme:
an infusion bottle cap assembly comprises a rubber plug and an inner sleeve, wherein the rubber plug and the inner sleeve are integrally formed by a double-color injection molding technology, and the inner sleeve is made of polyolefin materials.
Compared with the prior art, the scheme has the following beneficial effects:
prevent the rubber plug from invaginating into the infusion bottle: the rubber plug and the inner sleeve are integrally formed, and the inner sleeve is clamped on the outer cover, so that the situation that the rubber plug and the inner sleeve are separated and fall off in the puncturing process and then are sunk into the infusion bottle is not easy to occur.
Further, the rubber plug is made of thermoplastic elastomer TPE.
Safe material and less precipitation: the medical grade elastomer is used for manufacturing the rubber plug, so that the safety is improved;
less puncture scraps: due to the material characteristics, the quantity of puncture scraps is lower than that of rubber plugs made of conventional rubber materials;
the infusion bottle cap comprises an inner cap and an outer cap, wherein the inner cap is arranged inside the outer cap, and the inner cap is the infusion bottle cap assembly.
Compared with the prior art, the utility model has the following technical effects:
production efficiency promotes: because the rubber plug and the inner sleeve are formed in one step by a double-color injection molding technology, the production link does not need secondary assembly, the production process is saved, and the production efficiency is improved; and meanwhile, the possibility of bringing in external pollutants in the secondary assembly process is avoided.
On the basis of the technical scheme, the utility model can be improved as follows.
Preferably, the inner cap and the outer cap are connected by one of snap fit, welding, threading, bonding.
Preferably, the rubber plug is made of medical grade materials.
The further scheme has the beneficial effect that the isolation film is not required to be arranged separately to isolate the rubber plug from liquid in the bottle.
Preferably, the outer cover is provided with an easy-to-open structure.
Preferably, the easy-open structure is one of a film, a pull ring and a hollow frangible member.
The rubber plug surface in the original structure cover needs to be siliconized in the production process, so that the lubricity of the rubber plug is improved, the plugging operation is facilitated, and the rubber plug is prevented from being adhered or extruded and deformed in the storage, transportation, production and use processes. In the scheme, the modified thermoplastic elastomer is adopted, so that the use of silicone oil can be omitted.
