Description

A packaging bag suction nozzle and a packaging bag

technical field

The utility model relates to the field of beverage packaging, in particular to a packaging bag suction nozzle and a packaging bag.

Background technique

With the improvement of people's living standards, people's demand for beverages is increasing, making the demand for beverage packaging is also increasing. At present, there are many types of packaging for liquid beverages that are common on the market, such as cartons, stand-up pouches and plastic bottles. Among them, in order to facilitate people to use stand-up pouches, stand-up pouch manufacturers will set suction nozzles on the bag body. The existing suction nozzles include The mouth of the bag is sealed and connected to the opening of the bag, and the bottle cap that is sleeved outside the mouth and covers the opening of the mouth. The mouth and the bottle cap are made of PP or PE materials. The above-mentioned suction nozzles are limited by their manufacturing materials And the setting method, its sealing and barrier performance are poor, and the outside air can easily penetrate the mouth or bottle cap, or enter the stand-up pouch from the gap between the mouth and the bottle cap, so that the beverage in the stand-up pouch will breed bacteria and deteriorate; To improve the sealing performance of packaging bags, some packaging bag manufacturers use high-barrier materials to make packaging bags, but the sealing performance of such packaging bags is still greatly reduced due to the poor barrier performance of the suction nozzle.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a suction nozzle with simple structure and good sealing performance.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a packaging bag suction nozzle, including a mouth and a bottle cap for sealing the mouth, the lower side of the mouth is provided with a connecting part that is sealed and connected with the opening of the packaging bag , the mouth is provided with a liquid outlet channel running through both ends thereof, the liquid outlet channel communicates with the inside of the packaging bag, and the inside of the bottle cap is provided with an insertion part inserted into the liquid outlet channel of the mouth.

Compared with the prior art, the suction nozzle of a packaging bag of the present invention has an insertion part inside the bottle cap, and after the insertion part is inserted into the liquid outlet channel of the mouth, the liquid outlet channel of the mouth is then Sealing. Compared with the existing setting method of the nozzle that only covers the opening of the mouth, this setting method has better sealing performance. Through the double sealing of the outer wall of the mouth and the liquid outlet channel of the mouth, it can ensure that the outside world Gas cannot penetrate into the bag.

Preferably, the outer end surface of the bottom wall of the insertion part is provided with a barrier film, which can effectively improve the sealing effect of the insertion part on the liquid outlet channel of the mouth.

The gap between the liquid outlet channels of the mouth enters into the packaging bag.

Preferably, the length L of the insertion part is greater than or equal to the height H from the upper end of the bottle cap to the corresponding edge on the packaging bag. This arrangement can ensure the sealing effect of the insertion part on the liquid outlet channel.

Preferably, the surrounding wall of the insertion part is gradually reduced from top to bottom, and this arrangement facilitates the insertion of the insertion part into the liquid outlet channel of the mouth.

Preferably, the caliber of the liquid outlet channel gradually decreases from top to bottom, and this arrangement can ensure that the peripheral wall of the insertion part is in close contact with the liquid outlet channel of the mouth.

Preferably, the insertion part is provided with a groove with an open upper end, and the opening end of the groove penetrates the upper end surface of the bottle cap to communicate with the outside world. The cross section of the insertion part is in a "U" shape, thereby reducing the Cover materials, thereby reducing production costs and saving resources.

Preferably, the upper edge of the bottle cap extends downwards to form a convex wall, and the convex wall is screwed to the outer peripheral wall of the mouth; this setting facilitates the disassembly and assembly of the bottle cap and the mouth.

Preferably, a limiting boss is provided on the outside of the mouth, and a locking protrusion is arranged on the limiting boss; an anti-theft ring is provided at the lower end of the convex wall, and the anti-theft ring is engaged with the locking protrusion; by setting The card protrusion and anti-theft ring can prevent the bottle cap from being loosened by external force during transportation, so as to ensure the sealing effect of the bottle cap on the mouth.

Another object of the present utility model is to provide a packaging bag using the above-mentioned suction nozzle of the packaging bag, which includes a bag body for containing liquid food, an opening is arranged on the upper part of the bag body, and a suction nozzle is arranged on the opening.

Compared with the prior art, the packaging bag of the utility model has good airtightness and can effectively prevent the liquid food from breeding bacteria and deteriorating, thereby prolonging the storage time of the liquid food and ensuring the quality of the product.

Detailed ways

Below in conjunction with accompanying drawing, illustrate embodiment of the present utility model:

Embodiment one

Referring to Fig. 1 to Fig. 2, a packaging bag suction nozzle 1 of the present embodiment, a packaging bag suction nozzle 1, includes a mouth 2 and a bottle cap 3 for sealing the mouth 2, the lower side of the mouth 2 is provided There is a connecting portion 22 that is sealed and connected to the opening of the packaging bag. The mouth 2 is provided with a liquid outlet channel 20 that runs through both ends of the mouth. The liquid outlet channel 20 communicates with the inside of the packaging bag. The mouth 2 exits the insertion portion 31 of the liquid channel 20 .

The outer end surface of the bottom wall of the insertion part 31 is provided with a barrier film 4, and the barrier film 4 is made of a high barrier material with a thickness of 0.01-0.5mm. This arrangement can effectively improve the resistance of the insertion part 31 to the The sealing effect of the outlet channel 20 of the mouth 2.

The connection between the peripheral wall and the bottom wall of the insertion part 31 is provided with a circular arc chamfer, and the barrier film 4 extends to cover the circular arc chamfer.

The barrier film 4 extends upwards and covers the connection between the peripheral wall and the bottom wall of the insertion part 31, so that the outer side of the insertion part 31 can be closely attached to the liquid outlet channel 20 of the mouth 2, and the outside air can be prevented from entering the mouth. The gap between the insertion part 31 and the liquid outlet channel 20 of the spout 2 enters into the packaging bag.
