Description
Technical field
The utility model relates generally to sealing checkout equipment field, is specifically related to a kind of device for detecting sealability that is used for container.
Background technology
Whether people need detect the sealing of packing container usually, see whether there is leakage problem, qualified to judge packing of product quality, have therefore produced the sealing detection technique.Especially for the container of medicine, if there is leakage problem in container, the then easy microbiological contamination of medicine in the container or by other contaminating impurities according to the requirement of 1 pair of aseptic medicine of new edition GMP appendix, needs that more drug container is carried out sealing property and detects.
With the ampoule is example, and several ampoule leak hunting methods commonly used are as follows at present:
1, vacuum dyeing method.Place one to fill with in the container of aqueous solution of methylene blue ampoule to be checked, container decompression 30 minutes, vacuum tightness makes less negative pressure of the inner generation of ampoule less than 100mbar.When the venting vacuum chamber, if existing, ampoule leaks, and then ampoule will suck colored solutions, and whether the sealing that can judge ampoule by visual inspection is intact.
2, pressurization decoration method.This law is similar to last method, and different is that this law adopts pressurization, so just can make the external and internal pressure difference of ampoule significantly improve (as 4bar), thereby make the easier suction colored solutions of the ampoule that has seepage, the same sealing that adopts range estimation to judge ampoule.
3, autoclave decoration method.This method can make two steps of sterilizing and hunt leak operate in the same autoclave and once finish.Ampoule is placed in the autoclave, and sterilize with steam under pressure, temperature is 121 ℃, will be evacuated in the still after the cooling, with in the colored solutions suction still in the storage tank, ampoule is fully immersed in the colored solutions then.Feed sterilization pressurized air again, reach about 2.5bar malleation.The colored solutions that will be attached to the ampoule surface is rinsed well then, estimates judgement.
Above-mentioned three kinds of methods all need ampoule is immersed colored solutions, whether suck the sealing that colored solutions is judged ampoule by the visual inspection ampoule, therefore have following shortcoming:
1, owing to use a large amount of colored solutions, causes unnecessary waste, and environment is produced pollution.
2, the ampoule that is immersed in the colored solutions must clean up, and increases the employee work amount.
3, whether suck the sealing that colored solutions is judged ampoule in the naked-eye observation ampoule, take a lot of work, time-consuming, and the loss height, particularly during some minute leakage, naked eyes are difficult to observe, and reliability is low.
