Definitions
- the present invention relates to a soft packaging bag made of a thin laminated film for packaging and a method for injecting and packaging a liquid article to be packed in the packaging bag.
- a soft packaging bag made of a thin laminated film for packaging and a method for injecting and packaging a liquid article to be packed in the packaging bag.
- it is easy and reliable to remove and remove the air and other gases that have entered the packaging bag together with the liquid packaged item through the injection nozzle, etc.
- the unintentional entry of outside air into the packaging bag is surely prevented, and the packaged material in the bag is oxidized, fouled, etc.
- Patent Documents 1 to 3 disclose packaging bags including a liquid pouring nozzle having a check function. In these packaging bags, at the time of pouring out the liquid package, a spout is formed at the tip of the nozzle by removing the fused portion of the tip of the pouring nozzle by tearing with fingers, etc. The packaging bag is tilted so that the nozzle spout is oriented downward.
- the tip spout of the pouring nozzle made of a soft laminated film is opened separately on the front and back sides under the action of the head pressure of the package, so that the package can be dispensed as required. Can be tolerated.
- the soft packaging bag body contracts or shrinks by an amount corresponding to the dispensed volume without sucking outside air as the packaged items are poured out. It will be crushed and deformed.
- the packaging bag After dispensing the required amount of packaged goods by tilting the packaging bag, the packaging bag is returned to its original standing position to stop the dispensing, and the nozzle that has become wet with the packaged product is stopped based on the stoppage of the dispensing.
- the inner surface of the thin film of the package to be packaged intervenes due to the capillary action, etc., and at the same time, the width direction of the film on the front and back of the dispensing nozzle, in other words, the entire vertical direction In this way, the nozzle tip spout is sealed to reliably prevent outside air from entering the packaging bag.
- the packaged items in the bag are sufficiently protected from contact with the outside air during and after the dispensing as well as before the dispensing of the packaged items.
- oxidation, fouling and the like of the packaged items in the bag are effectively prevented.
- the above-mentioned close contact between the inner surfaces of the film on the front and back sides of the pouring nozzle is that the pouring nozzle is released from the action of the hydraulic head pressure by the rising and returning of the packaging bag, and returns to the original shape at the time of manufacture.
- the inner surfaces of the front and back films wetted by the packaged items are exposed to a reduced-pressure atmosphere and adsorbed to each other.
- This close contact will be performed automatically, and the packaging bag body that has been shrunk or crushed and deformed as the packaged material is poured out of the packaging bag is based on its inherent elastic restoring force, It becomes more reliable when the inside is made to have a reduced pressure tendency.
