Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The utility model will be further explained with reference to the following schematic examples, which are shown in the accompanying drawings. Various advantages of the present invention will become more apparent from the following description. The shapes and dimensions of the various elements in the schematic drawings are illustrative only and are not to be construed as embodying the actual shapes, dimensions and absolute positions.

Stopper cap portion and stopper neck portion

During the bottleneck of medicines such as freeze-dried powder was filled in to stopper neck portion, stopper lid portion lid was located outside the bottleneck, and the diameter of stopper lid portion is greater than stopper neck portion, and the one end and the stopper lid portion of stopper neck portion are connected, and the other end is the plug-in end.

The groove length direction of the first through groove and the second through groove is the radial direction of the plug neck part, and the groove depth direction is the radial direction of the plug neck part.

The groove depth of the first logical groove of axial along stopper neck is greater than the groove depth that the second led to the groove, and under half pressure stopper state, the sublimation solvent encloses synthetic gas vent discharge bottle with the bottleneck via first logical groove, and the stopper neck circumference surface except that the gas vent all with bottleneck looks butt, the butt area is bigger than two forks, trident, four forks plugs, and the jump stopper probability is little.

The total number of the first through grooves and the total number of the second through grooves are certain, the more the number of the first through grooves is, the faster the sublimation solvent is discharged, and the higher the plug jumping probability is. Specifically, the number of the first through grooves is one, and the number of the second through grooves is one or two. More preferably, on the basis of the single-fork rubber plug, a second through groove is additionally arranged, so that the rubber plug is cleaned and the utilization rate of freeze-dried powder is improved more obviously.

Diversion trench

The guide groove is used for introducing cleaning fluid and freeze-dried powder solvent to the bottom of the central blind hole; the included angle between the bottom surface of the diversion trench and the bottom surface of the central blind hole is an obtuse angle, the obtuse angle is more favorable for infiltration of a freeze-dried powder solvent, and is not favorable for adhesion of a freeze-dried powder solution, and the effect is similar to that of the fact that the bottom surface of the central blind hole is a spherical surface protruding towards the plug cover part; furthermore, when the end faces of the first through groove and the second through groove are opposite, the cleaning effect of the cleaning liquid and the utilization rate of the freeze-drying powder are higher.

The groove side surface of the diversion trench and the circumferential side surface of the central blind hole are in smooth transition, and the demoulding of the vulcanized rubber sheet at the chamfer of the rubber plug vulcanizing mold is more convenient and quicker.

The guiding gutter groove depth of groove bottom department that first logical groove and/or second led to the groove is the biggest, and operating personnel helps the solvent in to freeze-drying powder bottle after, rocks the bottle, and the above-mentioned structure of guiding gutter is that the solvent gets into central blind hole bottom more easily.

Furthermore, the outer surface of the plug neck is provided with an anti-jumping rib or an anti-jumping salient point, the anti-jumping rib is in a strip shape or a point shape and is arranged on the outer surface of the plug valve, or the anti-jumping rib is in an annular shape and is arranged on the periphery of the outer surface of the plug neck of the plug valve and the plug cover.
