Abstract
The utility model discloses a rubber plug with an elastic membrane. The rubber plug with the elastic membrane comprises a rubber plug body (1) and the elastic membrane (2). The neck portion (1.1) and the plug cap portion sealing plane (1.2) of the rubber plug body (1) are continuously coated with the elastic membrane (2) which is integrally formed with the rubber plug body through vulcanization; the elastic membrane (2) is a thermoplastic elastic body membrane and is of a two-layer and multi-layer structure; the rubber body (1) is made of butyl rubber, halogenated butyl rubber or polyisoprene rubber. Due to the fact that the continuously film-coating structure and the thermoplastic elastic body are taken as membrane materials, the one-step vulcanization forming of the film-coated rubber plug on a common production line can be achieved, the softness and the elasticity of products can be effectively controlled, the tightness of the film-coated rubber plug is largely improved, and further the shelf life of medicine is prolonged. The rubber plug with the elastic membrane facilitates the improvement of the binding force between the membrane and the rubber plug body, reduces the production cost and the energy consumption and improves the production efficiency of the film-coated rubber plug.
Description
Technical field
This utility model relates to the drug packing material field, is a kind of medical coated rubber plug specifically.
Background technology
Coated rubber plug is widely used on pharmaceutical product packaging because itself and medicine have the good compatibility.The coated rubber plug of prior art generally comprises rubber plug body, and part covers the inert plastic film on rubber plug body, thereby plays the effect of medicine and rubber plug body isolation, reduces the pollution that plug brings to medicine.
Because the performance of coated rubber plug depends on the performance of membrane material and the factors such as positional structure of overlay film, therefore to the selection of diaphragm with to lay position etc. be the key of product quality.In prior art, the diaphragm of use adopts plastic foil mostly, and its Main Ingredients and Appearance has Teflon plastics and polyethylene terephthalate plastics.Adopt plastic foil to have following defect: 1, easily cause the coated rubber plug case hardness to increase, air-tightness descends, thereby shortens the shelf-life of medicine; 2, the adhesive force of diaphragm is not strong, loosening or obscission easily occurs, thereby cause secondary pollution; 3, the coated rubber plug moulding process is comparatively complicated, usually needs special dies and equipment, and takes post-cure molding and secondary punch method, and production efficiency is low, and energy consumption is large.
In addition, prior art is taked the post-cure molding, and coated rubber plug easily produces local over cure and plug neck root junction is crude and slight crack, affects the yield rate of plug, affects pliability and the elasticity of plug, and has increased workload to rubber plug cleaning.
The utility model content
The technical problems to be solved in the utility model is, provides that a kind of air-tightness is good, diaphragm strong adhesion, production cost be low, energy savings, and the plug that is covered with elastica of being convenient to make.
Technical solution of the present utility model is, a kind of plug that is covered with elastica of following structure is provided, and comprises rubber plug body and elastica; The plug cervical region of described rubber plug body and plug coronal seal plane are coated with continuously by sulfuration and rubber plug body fusion all-in-one-piece elastica, and described elastica is thermoplastic elastomer films.
This utility model compared with prior art has the following advantages: this utility model is owing to having adopted continuous structure of film and thermoplastic elastomer (TPE) as diaphragm material, realized the production coated rubber plug can be on the normal conventional production line sulfidization molding once, effectively control pliability and the elasticity of product, greatly improve the air-tightness of coated rubber plug, thereby extended the shelf-life of medicine.This utility model also helps the adhesion that improves between diaphragm and rubber plug body, reduces production costs and energy resource consumption, improves the production efficiency of coated rubber plug.
As improvement, described elastica is two layers or more structure; This project organization can effectively overcome the defect that easily there is pin hole in the monolayer diaphragm, has improved the reliability of product.
As improvement, described rubber plug body is made by butyl rubber, halogenated butyl rubber or polyisoprene rubber; The compatibility of plug and the medicine of elastica can be guaranteed like this to be covered with, the sealing when plug uses can be guaranteed again.
The accompanying drawing explanation
Fig. 1 is the structural representation that this utility model is covered with the plug of elastica.
As shown in the figure 1, rubber plug body, 2, elastica, 1.1, the plug cervical region, 1.2, plug coronal seal plane.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, this utility model is covered with the plug of elastica, comprises rubber plug body 1 and elastica 2; The plug cervical region 1.1 of described rubber plug body 1 and plug coronal seal plane 1.2 are coated with continuously by sulfuration and rubber plug body fusion all-in-one-piece elastica 2, and described elastica 2 is thermoplastic elastomer films.
Described elastica is two layers or more structure; Thermoplastic elastomer films can be referred to as the TPE film.Described plug cervical region 1.1 refers to the part that rubber plug body 1 communicates with the medicine bottle inner chamber.
Described rubber plug body 1 is made by butyl rubber, halogenated butyl rubber or polyisoprene rubber; Between rubber plug body and elastica, by vulcanization, fuse into one.
Below only with regard to this utility model preferred embodiment, be described, but can not be interpreted as it is limitations on claims.This utility model not only is confined to above embodiment, and its concrete structure allows to change, etc.In a word, all various variations of doing in the protection domain of this utility model independent claims are all in protection domain of the present utility model.
Claims (3)
1. plug that is covered with elastica, comprise rubber plug body (1) and elastica (2), it is characterized in that: the plug cervical region (1.1) of described rubber plug body (1) and plug coronal seal plane (1.2) are coated with continuously by sulfuration and rubber plug body fusion all-in-one-piece elastica (2), and described elastica (2) is thermoplastic elastomer films.
2. the plug that is covered with elastica according to claim 1, it is characterized in that: described elastica is two layers or more structure.
