Abstract

The invention relates to a method for preventing fragments on the inner surface of a medical ampoule bottle. Sealed hot air is formed in the bottle, a sealed ball head is formed at the bottle mouth, and the hot air inside the bottle is ejected out when a flame knife is adopted to cut, so as to eject out the fragments at the bottle mouth, so that both the use security of medical glass is ensured, and no extra process steps are increased.

Description

A kind of method of avoiding medicinal ampoule internal surface to produce chip

Technical field

The present invention relates to the manufacturing process of medicinal glass bottle, especially a kind of method of avoiding medicinal ampoule internal surface to produce chip.

Background technology

Medicinal glass bottle comprises ampoule, is a kind of bottle of sealing, is usually used in depositing the medicine of injection and vaccine, serum etc., and is therefore very high to the requirement of safety and sanitation.

In traditional technology, the cut-out mode of the bottleneck of ampoule is to utilize mechanical external force vertically downward, cutting of bottleneck is neat, but because mechanical external force itself has rigidity, can make glass produce chip, like this, glass chip meeting small amount of residual is in ampoule when cutting off, and this can produce great hazardness to later medicinal encapsulation.

Summary of the invention

The technical problem to be solved in the present invention is: propose a kind of method of avoiding medicinal ampoule internal surface to produce chip.

The technical solution adopted in the present invention is: a kind of method of avoiding medicinal ampoule internal surface to produce chip may further comprise the steps:

1) Glass tubing is sandwiched on the upper grip, lower chuck is drop-down to be drawn;

2) utilize flame to cut off at the middle part of following pull end;

3) form the bulb of a sealing in the upper end of ampoule, and at ampoule interior sealing warm air;

4) utilize thin slice flame to cut off the bulb of ampoule upper end closed, make the warm air of ampoule interior spray;

5) in the warm air ejection of ampoule interior, form smooth bottleneck on the top of ampoule.

For the bottleneck that guarantees ampoule neat, step 2 of the present invention) in the flame that uses be horizontal-jet; The cutting direction of the thin slice flame that uses in the described step 4) is cut off as level.

The invention has the beneficial effects as follows: the warm air that in bottle, forms sealing, form the bulb of sealing at bottleneck, hot gas when the recycling flame knife cuts in the bottle outwards ejects, at bottleneck chip is sprayed in the bottle, the security that pharmaceutical glass uses can either be guaranteed, extra processing step need not be increased again.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is the mechanical cutting process flow sheet of prior art;

Fig. 2 is process sequence diagram of the present invention.

Embodiment

The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.

As shown in Figure 1, traditional old-fashioned cut-out mode is to utilize the emery wheel rotation vertically downward, cutting of bottleneck is neat, but because emery wheel itself has particulate matter, and the rigidity of emery wheel can make glass produce chip, like this, glass chip meeting small amount of residual is in ampoule when cutting off, and this can produce great hazardness to later medicinal encapsulation.

Technology of the present invention is at first utilized flame spraying to cut off and is formed ampoule work in-process and the warm air that forms the sealing bulb and form sealing in ampoule bottle chamber in the upper end of ampoule as shown in Figure 2; Cut off the sealing bulb with thin slice flame afterwards, the warm air in the bottle can eject thereupon, also can take away in the ampoule along with spouting warm air even can produce chip like this in cutting-off process, thereby increases the security that ampoule uses.

Just the specific embodiment of the present invention of describing in the above specification sheets, various not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field after having read specification sheets can to before described embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.

Claims

1. method of avoiding medicinal ampoule internal surface to produce chip is characterized in that following steps:

2) utilize flame to cut off at the middle part of following pull end;

2. a kind of method of avoiding medicinal ampoule internal surface to produce chip as claimed in claim 1, it is characterized in that: the flame that uses described step 2) is horizontal-jet.

3. a kind of method of avoiding medicinal ampoule internal surface to produce chip as claimed in claim 1, it is characterized in that: the cutting direction of the thin slice flame that uses in the described step 4) is cut off as level.
