Abstract
The utility model relates to a medical composite rubber bottle stopper which is compounded from a silicon rubber cork body and butyl rubber coating, wherein, the butyl rubber coating can be of a layer or two layers, and the butyl rubber coating is coated on the inner surface or/and the outer surface of the silicon rubber cork body. Because inexpensive silicon rubber is used as the main material, and a small quantity of expensive butyl rubber is used as the thin coating, the cost of material is greatly reduced and further the manufacturing cost of the medical composite rubber bottle stopper is reduced. With the unique hydrophobicity of the silicon oxygen bond, the silicon rubber can shield liquid phase; with the structural density being larger than the structure density of the silicon rubber, the butyl rubber coated on the silicon rubber cork body can protect medicament packing material against air permeability; therefore, the medical composite rubber bottle stopper can meet the medicament packing requirement, can be manufactured with low cost and can replace the prior butyl rubber bottle stopper.
Description
Technical field
This reality is novel to relate to a kind of bottle stopper, and especially a kind of pharmaceutical compounded rubber bottle stopper belongs to a kind of medical apparatus and instruments or laminar rubber products.
Background technology
The overall structure that existing various pharmaceutical bottle closure of rubber all is homogeneity, the body of rubber material that it adopted is a butyl rubber.At present can the whole nation man pharmaceuticals packaging material comprehensive, particularly security performance mainly contains butyl rubber and silicone rubber.But silicone rubber is because its special microstructure, cause its permeability good and can not satisfy the seal request of drug packaging, form present butyl rubber material and dominated the situation of drug packaging exclusively, bottle closure of rubber as bottled medicaments such as existing saline bottles all is to be made by butyl rubber, but the main dependence on import of butyl rubber, cost an arm and a leg, be about silicone rubber price 2-3 doubly, this also is the high always main cause of price of medical grade rubber bottle stopper.
Summary of the invention
The purpose of this utility model is in order to overcome the too high weak point of butyl rubber cost, designs a kind ofly can meet the medical drugs packing instructions, the medical compounded rubber bottle stopper that can reduce production costs again.
Medical compounded rubber bottle stopper of the present utility model mainly is to be composited by silicone rubber cock body and butyl rubber cover layer.Described butyl rubber cover layer can be one deck or two-layer, when the butyl rubber cover layer is one deck, then covers on the inner surface of silicone rubber cock body or on the outer surface; When butyl rubber cover layer when being two-layer, then topped respectively on the inner surface of silicone rubber cock body and on the outer surface.Described medical compounded rubber bottle stopper is composited through isotype sulfuration by silicone rubber cock body and the butyl rubber cover layer after the integer respectively again.
Medical compounded rubber bottle stopper of the present utility model, owing to use cheap silicone rubber to be primary raw material, expensive butyl rubber is only made thin cover layer and is used, consumption is less, material cost can significantly be descended, and then reduce production costs.Because of having unique hydrophobicity, the siliconoxygen bond of silicone rubber forms shielding again to liquid phase, skin or internal layer are covered by butyl rubber, utilize the characteristic of butyl rubber density of texture greater than silicone rubber, satisfy the air tight property requirement of medicated bag material, make the bottle stopper can be on the basis that meets the medical drugs packing instructions, have the low advantage of production cost again, can replace existing butyl rubber bottle stopper to use.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is another kind of structural representations of the present utility model;
Accompanying drawing 3 is the third structural representations of the present utility model.
The specific embodiment
Referring to accompanying drawing, 1 among the figure is the silicone rubber cock body, the 2nd, and the butyl rubber cover layer.Medical compounded rubber bottle stopper of the present utility model mainly is composited by silicone rubber cock body 1 and butyl rubber cover layer 2.Butyl rubber cover layer 2 wherein can be one deck and also can be two-layerly, and when selecting one deck for use, butyl rubber cover layer 2 covers on the outer surface of silicone rubber cock body 1, as shown in Figure 1; Also can cover on the inner surface of silicone rubber cock body 1, as shown in Figure 2.When selecting for use when two-layer, butyl rubber cover layer 2 can cover respectively on the inner surface of silicone rubber cock body 1 and on the outer surface, as shown in Figure 3.During production, silicone rubber cock body 1 and butyl rubber cover layer 2 difference film-making earlier integer can be got final product through isotype sulfuration composite molding again.Because the Main Ingredients and Appearance of two kinds of materials is silicon and carbon, under certain sulfuration process, both can form the netted integral body of microcosmic under the effect of crosslinked and vulcanizing agent.After adopting technique scheme, bottle closure of rubber just becomes an incorporate integral body that is composited by two kinds of unlike materials.Give full play to and use silicone rubber and butyl rubber advantage separately to overcome the other side's shortcoming, both satisfied the complex art of medical packaging material, have tangible economic implications again, can replace existing butyl rubber bottle stopper to use.
Claims (3)
1, a kind of medical compounded rubber bottle stopper is characterized in that mainly being composited by silicone rubber cock body and butyl rubber cover layer.
2, medical compounded rubber bottle stopper according to claim 1 is characterized in that described butyl rubber cover layer is one deck or two-layer, when the butyl rubber cover layer is one deck, then covers on the inner surface of silicone rubber cock body or on the outer surface; When butyl rubber cover layer when being two-layer, then topped respectively on the inner surface of silicone rubber cock body and on the outer surface.
3, medical grade rubber composite bottle stopper according to claim 1 and 2 is characterized in that being composited through isotype sulfuration by silicone rubber cock body and butyl rubber cover layer after the integer respectively again.
