Description

Medicinal tectorial membrane plug

Technical Field

The utility model relates to a tectorial membrane plug technical field specifically is a medicinal tectorial membrane plug.

Background

The coated rubber plug is one of the medicinal capsules, is a product of coating a layer of high-barrier film on the surface of the conventional medicinal capsule contacted with the medicament, can prevent the butyl capsule from contacting with the medicament, reduces the release of active substances in the butyl rubber plug, improves the long-term stability of the medicament, and solves the problems of medicament pollution, medicament safety, quality and the like. Along with the strict regulation on medicine quality in the country in recent years, the requirement of medicine enterprises on medicinal rubber plugs is improved, the film-coated rubber plug industry is rapidly developed, and as the film-coated rubber plug industry in China starts late, batch production can be realized currently, enterprises with stable product quality are fewer, and the price of the film-coated rubber plug is high, the film-coated rubber plug is low in permeability in the domestic market at present. In the field of medical rubber plugs, the conventional rubber plug taking halogenated butyl rubber as a raw material has high cost performance and higher application demand in China, the coated rubber plug accounts for 91 percent and is used for a medical infusion bottle or a medicine bottle cap, the coated rubber plug is usually made of rubber and aims to keep the sealing property of medicines, the coated rubber plug is a high-end product in the medical rubber plug, although the coated rubber plug has better performance, the coated rubber plug is expensive, the permeability in the domestic market is relatively low, and the future development potential of the industry is huge. The application range of the film-coated rubber plug is wide, the film-coated rubber plug is required to be applied in the field of new vaccines in 2020, and the market demand of the film-coated rubber plug in China is continuously increased. In the aspect of production, limited by patents, equipment and the like, few enterprises capable of producing the film-coated rubber plug stably in a large scale are in China, and the market concentration is high. In general, the market of the film-coated rubber plug is not fully competitive, and the future development potential is huge

The existing film-coated rubber plug has the defects that:

patent document CN106426699B discloses a secondary molding process of a film-coated rubber stopper for medical use, and the protection right item "comprises the following specific steps: (1) preparing rubber raw materials: 100phr of halogenated butyl rubber, 50-80phr of calcined kaolin, 3-10phr of zinc oxide, 1-2phr of stearic acid, 1-5phr of vulcanized resin and 1-5phr of pigment; (2) The plug neck is molded by one-step compression, and the circumferential wall of two thirds of the plug neck and the bottom surface of the plug neck are coated with film layers; (3) And filling the coated plug neck into a mold, and filling rubber raw materials for secondary mold pressing, so that the coated plug neck and the coated plug head are combined into a whole. The invention has the beneficial effects that: the secondary forming technology of the medical film-coated rubber plug is a unique secondary forming technology, namely, a film is coated on the plug neck part of the rubber plug in direct contact with a medicine, thereby isolating the rubber from the medicine in direct contact with the medicine, avoiding the pollution of the rubber plug to the medicine, but not coating the sealing surface of the rubber plug, ensuring that the rubber plug keeps the due elastic sealing effect, but most of the existing film-coated rubber plugs have poor sealing performance, only rely on the sealing between the rubber and the bottle wall, and the sealing performance is poor.
