Abstract

The utility model discloses an anti-jumping rubber plug for lyophilized powder, which belongs to the field of rubber plugs and comprises a plug neck. The periphery of the upper portion of the plug neck is provided with a protruding ring, a through groove which transversely penetrates through the plug neck is arranged below the protruding ring, and the plug neck is divided into two plug clacks by the through groove. Because the through groove is arranged in the plug neck, when the rubber plug is plugged into a bottle opening, the air in the bottle is communicated with the air outside the bottle, and the anti-jumping rubber plug is favorable for the discharge of compressed air in the bottle from the through groove, thereby avoiding plug jumping. The protruding ring arranged on the upper portion of the plug neck increases the friction between the plug neck and the bottle opening, further prevents the rubber plug from jumping out, and improves the sealing performance of the rubber plug simultaneously.

Description

Freeze-dried powder is used anti-jump plug

Technical field

The utility model belongs to the plug field, is specifically related to a kind of freeze-dried powder and uses plug.

Background technology

Because special preparation technology and the pharmacological property of freeze-dried powder, so the requirement of the package encapsulation of freeze-dried powder is stricter than common drug.Common used plug comprises plug hat and plug neck, and the plug neck is the center that downward convex shape is connected in plug hat lower surface, and the plug neck is a hollow cylindrical, and its external diameter equals or be slightly larger than the internal diameter of bottleneck, satisfies the seal request of freeze-dried powder at present through the plug neck of lengthening plug.But in actual application; Owing to strengthened the length of plug neck, make the plug neck fill in bottleneck fully and then need compress gas in the more bottle, form bigger interior pressure; Make plug be difficult to more fill in fully; And the plug phenomenon is jumped in as easy as rolling off a log generation, and the plug that lands can cause new pollution, and using or directly scrap all after the repeated washing to increase cost.

Summary of the invention

The utility model technical matters to be solved provides a kind of freeze-dried powder and uses anti-jump plug, makes plug fill in bottleneck easily fully and avoids take place jumping the plug phenomenon.

For solving the problems of the technologies described above; The technical scheme of the utility model is: provide a kind of freeze-dried powder to use anti-jump plug, comprise the plug neck, it is characterized in that: the periphery on said plug neck top is provided with bulge loop; The below of bulge loop has laterally runs through the groove of filling in neck, and groove will be filled in neck and be separated into two plug lobes.

The periphery of each plug lobe all is covered with at least one horizontal raised line.

The beneficial effect of the utility model is:

1, because plug has groove in the neck, when making plug fill in bottleneck, gas communicates with the outer gas of bottle in the bottle, and the gas that is beneficial in the bottle is by compression discharged from groove, thereby has avoided jumping to fill in the generation of phenomenon; The bulge loop that plug neck top is provided with has increased the friction force of plug neck and bottleneck, prevents that further plug from jumping out, and has strengthened the sealing property of plug simultaneously.

2, because the periphery of plug lobe is covered with horizontal raised line, can make between plug lobe and bottleneck contact to change the contact of line face into by the face face, fill in lobe and filled in bottleneck more easily.

3, the utility model is simple in structure, and preceding cleaning easy to use is more suitable for practical application.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is that the B of Fig. 1 is to view.

Among the figure: 1, plug hat; 2, plug neck; 3, bulge loop; 4, plug lobe; 5, groove; 6, raised line; 7, raised line.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.

In the utility model, the end that plug is contacted with bottleneck in use at first is the lower end, accordingly its other end is defined as the upper end; With radially being defined as laterally of plug, accordingly it axially is defined as vertically.

Like Fig. 1,2, shown in 3; The plug neck 2 of the utility model is the center that downward convex shape is connected in plug hat 1 lower surface, and the periphery on plug neck 2 tops is provided with bulge loop 3, has increased the friction force of plug neck 2 with bottleneck; Reduce the probability that plug is jumped out, strengthened the sealing property of plug simultaneously.The below of bulge loop 3 has laterally runs through the groove 5 of filling in neck 2; Groove 5 will be filled in neck 2 and be separated into two plug lobes 4, make plug when filling in bottleneck, and gas communicates with the outer gas of bottle in the bottle; The gas that is beneficial in the bottle is by compression discharged from groove 5, thereby has avoided jumping the generation of plug phenomenon.Periphery of each plug lobe 4 vertically is covered with two horizontal raised

lines

6,7, and raised line 6 length of bottom are greater than raised line 7 length on top, can make between plug lobe 4 and bottleneck contact by the face face to change the contact of line face into, fills in lobe 4 and is filled in bottleneck more easily.

It is to be noted; Above-mentioned embodiment only is the utility model preferred embodiment; For those skilled in the art, under the prerequisite that meets the utility model principle of work, any be equal to or similar replacement all falls in the protection domain of the utility model.

Claims

1. a freeze-dried powder is used anti-jump plug, comprises the plug neck, it is characterized in that: the periphery on said plug neck top is provided with bulge loop, and the below of bulge loop has laterally runs through the groove of filling in neck, and groove will be filled in neck and be separated into two plug lobes.

2. use anti-jump plug according to the described freeze-dried powder of claim 1, it is characterized in that: the periphery of said each plug lobe all is covered with at least one horizontal raised line.
