CN2649496Y - Short-neck stopper - Google Patents

Abstract

The utility model discloses a short neck plug used for medicine packaging, maily consisting of a head and a neck. The height of the neck is 2 to 4.5 mm high with an anti-bouncing vein. As the height of the bottle neck is controlled within 2 to 4.5 mm, the direct contact surface with the medicine is reduced and the contamination probability of the medicine is effectively reduced. The consumption of raw materials is reduced, the production cost is reduced, and the overall size of the rubber plug is reduced, so that the bottle may not be easy to be tilted. The anti-bouncing vein reduces the chance of plug bounce.

Description

Short-neck stopper

Technical field

The utility model relates to a kind of medicinal bottle stopper, particularly a kind of improved Short-neck stopper that is used for drug packaging.

Background technology

Medicinal bottle stopper is a kind of product that is used for drug packaging, plays the leak free effect.Medicinal bottle stopper mainly is made up of bizet and neck, and there are acupuncture ring and some radiant rays or radiation point in the bizet surface, plays guiding acupuncture and motion smoothness on guide rail; Neck is the part that directly contacts with medicine, seals.Neck of bottle stopper in the past is cylindrical, and the top is by conical surface transition.For making plug at the bottleneck jam-pack, neck height design-calculated is than higher, and is big with the direct contact area of glass bottle and medicine.This design has following shortcoming: the one, because the neck area is big, contaminated probability height causes medicine easily by the neck foreign substance pollution; The 2nd, plug overall dimensions height causes crank, and easily overturning has reduced production efficiency; The 3rd, raw materials consumption is big, plug cost height.

Summary of the invention

The purpose of this utility model provides a kind of little with medicine direct contact area, and plug is difficult for contaminated, and center of gravity is low, not prone to tip over, and raw materials consumption is little, the Short-neck stopper that cost is low.

The purpose of this utility model is achieved in that a kind of Short-neck stopper, comprises bizet 1 and neck 2, and neck 2 highly is the 2-4.5 millimeter.Neck 2 is provided with anti-jump muscle 3.

Short-neck stopper provided by the utility model, because the height of neck of bottle stopper is controlled between the 2-4.5 millimeter, the direct contact area minimizing with medicine has reduced the contaminated probability of medicine effectively; Reduce raw-material input and reduced productive costs; Also make simultaneously the plug overall dimensions reduce not prone to tip over; Anti-jump muscle has reduced the generation of jumping the plug phenomenon.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

The utility model adopts following structure: a kind of Short-neck stopper, comprise bizet 1 and neck 2, and neck 2 highly is the 2-4.5 millimeter.Neck 2 is provided with anti-jump muscle 3.

The utility model is controlled at the height of neck of bottle stopper between the 2-4.5 millimeter, makes the direct contact area of neck and medicine be reduced to the 1.8-3.8 sq cm, has reduced the contaminated probability of medicine.During use, bottle stopper is pressed into the medicine bottle mouth, anti-jump muscle 3 is just in time embedded in the deep-slotted chip breaker of molded bottleneck, make the plug jam-pack at bottleneck.

Claims (2)

1, a kind of Short-neck stopper comprises bizet (1) and neck (2), it is characterized in that: neck (2) highly is the 2-4.5 millimeter.

2, Short-neck stopper according to claim 1 is characterized in that: neck (2) is provided with anti-jump muscle (3).
