Abstract

The invention relates to a collecting pipe cap. The collecting pipe cap comprises a pipe body and a sealing plug. The pipe body is of a hollow cylindrical structure. A holding clamping groove used foraccommodating the sealing plug is arranged between the top and bottom of the pipe body. The diameter of the top inner wall of the holding clamping groove is smaller than that of the bottom inner wallof the holding clamping groove. A sealing plug body is of a three-layered structure. The diameter of an upper layer plug body is smaller than that of a lower layer plug body, and the diameters of theupper layer plug body and the lower layer plug body are smaller than that of a middle layer plug body, so that a left-right double ring structure is formed; in addition, the two sides of the upper layer plug body and the middle layer plug body of the sealing plug are provided with arc-shaped structures correspondingly; and the holding clamping groove is matched with the middle layer plug body ofthe sealing plug in size and shape. The collecting pipe cap has the advantages that the airtightness is good, mounting, pulling and plugging are convenient, in addition, the structure is simple, the practicability is high, and operation and using are convenient.

Description

technical field [0001] The invention relates to the technical field of cap closing plugs, in particular to a collecting tube cap. Background technique [0002] The medical sealing cork has a certain shape and size of the sealing elastomer product, which is used for sealing the mouth of medical bottle-shaped containers such as glass and plastic. Its structure can be roughly divided into three types: conical, T-shaped and flanged; according to the application, it can be divided into antibiotic bottle stoppers, biological drug bottle stoppers, spray drug bottle stoppers, and infusion bottle stoppers. The rubber material of the bottle stopper must not contain harmful soluble substances such as lead, mercury, arsenic, barium, etc., and has no effect on the medicine that can be loaded, and the bottle stopper itself must not have ejection. Generally, it is made of rubber materials such as NR, IIR and SBR, and is produced by molding, and is widely used in the pharmaceutical and med...
