Abstract
The utility model relates to a novel special rubber plug for powder preparation, which belongs to the field of the dedicated container component for medical or pharmaceutical purposes. The novel special rubber plug comprises a circular rubber plug body with a seal ring, and is characterized in that the central part of the upper end of the circular rubber plug body is depressed inwards, the vertical section of the depressed part has an inverted conical structure, and in addition, the vertical section of the seal ring integrated with the circular rubber plug body has a conical structure. Based on the improvement of the prior art, the puncture part with a special structure is arranged on the circular rubber plug body, the lower end of the seal ring is provided with the arc-shaped structure for embedding, and simultaneously the central position of the circular rubber plug body has a depressed structure, thereby reducing the material use, facilitating the pharmaceutical packaging and the puncture in the use of the medical unit, and greatly reducing the production costs.
Description
Technical field
This utility model belongs to the container parts field that is exclusively used in medical science or medical purpose, is specifically related to the special-purpose plug of a kind of novel powder preparation.
Background technology
Butyl rubber bung is all kinds of medicinal glass bottles plugs commonly used, the plug structure of prior art is mostly the upper surface is the plane, and the sealing ring end face that contacts with vial also is regular planar structure, the plug of similar structures finds to be subjected to the influence of plug structure in the application process of pharmaceutical production unit and medical institutions, existed and after the pharmaceutical preparation fill, be difficult to encapsulation, and rubber plug body is difficult to puncture with pin, simultaneously, the plug materials of this structure are more, caused the production cost of plug higher, therefore need improve, so that the encapsulation of medicament to prior art, and the puncture when being convenient to medical institutions and using, and can significantly reduce production costs.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of encapsulation of being convenient to medicament is provided, and the puncture when being convenient to medical institutions and using, and the special-purpose plug of the novel powder preparation that can significantly reduce production costs.
This utility model is achieved through the following technical solutions:
It is the special-purpose plug of a kind of novel powder preparation, comprise the circular rubber plug body that has sealing ring, the present technique main points are that the centre of the upper end of circular rubber plug body caves inward, this vertical section in depression position is inverted cone-shaped structure, in addition, with the tapered structure of the vertical section of the sealing ring of circular rubber plug body one.
The bottom of described sealing ring is arc-shaped structure.
In addition, big contraction occurs for fear of plug sealing back in transportation and storage process, circular rubber plug body upper end radially is processed with at least 3 strip reinforcements ringwise.
This utility model is after carrying out above-mentioned improvement to prior art, owing to will design the site of puncture of special construction on the circular rubber plug body, and with the arc-shaped structure of the bottom of sealing ring design for the ease of embedding, be designed to the structure of depression simultaneously in circular rubber plug body centre, also reduced the use of material, therefore be convenient to the encapsulation of medicament, and the puncture when being convenient to medical institutions and using, and the advantage that can significantly reduce production costs.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described in further detail:
Fig. 1: mounting structure sketch map of the present utility model.
The specific embodiment
As shown in Figure 1, the special-purpose plug of this novel powder preparation, comprise the circular rubber plug body 1 that has sealing ring, the present technique main points are that the centre 3 of the upper end of circular rubber plug body 1 caves inward 5, this vertical section in 5 positions that caves in is inverted cone-shaped structure, in addition, with the tapered structure 4 of sealing ring 2 vertical sections of circular rubber plug body 1 one.
The bottom of described sealing ring 2 is arc-shaped structure 6, and the distance of sealing ring bottom and upper end is 2～5 millimeters.
In addition, big contraction occurs for fear of plug sealing back in transportation and storage process, circular rubber plug body upper end radially is processed with at least 3 strip reinforcements 7 ringwise.
The utility model is after carrying out above-mentioned improvement to prior art, owing to will design the puncture of special construction on the circular rubber plug body The position, and with the arc-shaped structure of the bottom of sealing ring design for the ease of embedding, establish in circular rubber plug body centre simultaneously Therefore count the structure into depression, also reduced the use of material, be convenient to the encapsulation of medicament, and when being convenient to medical institutions and using Puncture, and the advantage that can significantly reduce production costs.
Claims (4)
