The leakage of the pickle bottle and the expansion of the lid are caused by various factors.
The first bottle mouth is not smooth, that is, the bottle mouth caused by the glass bottle manufacturer in the production process is defective or circular, so the water bottle lid will undoubtedly leak steam, so there will be leakage.
The second reason is that the mouth of the bottle has cold fried patterns, such bottle mouth must be pointed at the lighting effect can be seen, such glass bottles are also poor goods, just started canned good pickles pumped vacuum pump to see nothing, the lid safety button will suck down, for a period of time or after a night the lid safety button popped up, which confirms that pickles bottle no vacuum pump, Oil leakage will occur, so that glass bottles are not qualified products, there are many unscrupulous businesses in the production of not through careful testing caused by customer damage.
The third kind of leakage problem is caused by the lid, we all know that the lid is made of tin, and many cover factories in order to better save costs buy thin tin, that is, we often say non-standard tin, the lid is made of tin is very easy to slip, not tight, so it will also cause glass bottles to leak. There are also customers the purchase covers from the store to hide the market, themselves are ultra-low temperature canned goods, partial to the glass bottle factory salesman said into high temperature canned, conscious of high temperature is no doubt better than ultra-low temperature.
It is wrong to think that, because the high-temperature lid must be 121° to give full play to its sealing characteristics, (121° must continue to heat up for 20 minutes) can not reach this temperature there is no doubt that leakage problems will occur, customer goods if the high-temperature canned ultra-low temperature lid, canned good leakage problems will occur.
