Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of beverage packaging bags, and relates to a beverage packaging bag. BACKGROUND

[0002] At present, a bulk sale mode of packing beverages for take-out is popular in the market, and a container is needed to package the bulk beverages in this mode so as to facilitate consumers to purchase and carry. In order to facilitate carrying and save costs, most of the containers on the market are soft packaging bags. For example, a bagged beer disclosed in Chinese patent CN201006811Y comprises a closed bag body, the bag body is provided with a liquid outlet, the liquid outlet is a pipe opening with external threads in order to facilitate users to use and pour, a bottle cap is threadedly connected to the pipe opening, and two symmetrical conical bodies are arranged at the lower part of the pipe opening to facilitate connection with the bag body to form a liquid cavity.

[0003] During the bulk sale and supply of liquid beverages, the filling and supply of liquid are inevitably involved. The filling process of the above packaging bag for bulk packing of beverages is as follows: the bottle cap is unscrewed, the pipe opening is then butt-jointed to a filling machine for filling, and the bottle cap is screwed back after filling is completed. However, for some beverages, the shelf life is relatively short, and the freshness will be greatly reduced once the beverages are in contact with air, which directly affects the drinking taste. For example, draft beer, which is beer filtered by diatomite without sterilization, has a fresh taste, and the yeast contained in the draft beer has the effects of promoting gastric juice secretion, improving appetite and strengthening digestion. The draft beer can only be fresh for one or two days at room temperature, and the draft beer will affect the taste once it is in contact with air.

[0004] Therefore, for beverages with high requirements for fresh taste, the structure of the above packaging bag leads to the following defects in the filling process: the bottle cap needs to be screwed and disassembled, and the liquid in the bag will be in contact with air during this period, chemical reactions will occur, the liquid will gradually deteriorate, the original flavor will be lost, and the freshness of the filled liquid will be difficult to guarantee, and even the fresh taste of the beverage will be directly lost, which is difficult to meet the drinking requirements of users. Moreover, the operation of repeatedly screwing and unscrewing the bottle cap is relatively complicated, and the filling operation speed is relatively slow, which seriously affects the user experience for packing take-out products. SUMMARY

[0005] The present application aims at the above problems existing in the prior art, and provides a beverage packaging bag, and the technical problem to be solved by the present application is how to improve the filling speed of the packaging bag while improving the freshness of the packed beverage.

[0006] The beverage packaging bag of the present application comprises a bag body, a connector fixed to the bag body, and a bag cover detachably connected to the connector, characterized in that the connector is provided with independent liquid inlet and outlet channels, the liquid inlet channel is provided with a one-way valve for allowing liquid to flow in from outside to inside in a one-way manner, the bag cover is provided with a filling opening communicating with the inlet of the one-way valve, and the bag cover covers the liquid outlet channel to seal the liquid outlet channel.

[0007] Compared with the prior art, the present application improves the structure of the connector and the bag cover of the beverage packaging bag, so that the bag cover of the packaging bag does not need to be disassembled during beverage filling, completely changes the filling operation of the packaging bag, and achieves the purpose of improving the freshness and filling speed of packed beverages. Specifically, the independent liquid inlet channel and the liquid outlet channel are designed in the connector, and the one-way valve is arranged in the liquid inlet channel, so that the liquid can only flow in from outside to inside in a one-way manner, and the liquid can only flow out through the liquid outlet channel. Based on the design of the above-mentioned connector structure, the structure of the bag cover is designed, that is, the filling opening communicating with the inlet of the one-way valve is designed on the bag cover, and the bag cover covers the liquid outlet channel to seal the liquid outlet channel. After the above-mentioned design, when the liquid is filled by using the packaging bag, the filling machine can directly connect to the bottle cover and open the one-way valve to achieve filling. After filling is completed, the one-way valve is automatically reset to ensure the sealing of the liquid inlet channel. When the liquid needs to be poured out for drinking, the bag cover only needs to be opened, and the liquid can also flow out normally through the liquid outlet channel. That is to say, the packaging bag does not need to be disassembled during liquid filling, which makes the filled liquid not in contact with the outside air during the entire filling process, so that the filled liquid can be transferred from the filling machine to the packaging bag in its original state for preservation. Compared with the prior art, the freshness of the packed liquid is greatly improved. At the same time, the bag cover does not need to be disassembled, which makes the filling operation more convenient and helps to improve the filling speed.

[0008] In the above-mentioned beverage packaging bag, the liquid inlet pipe is fixed in the connector, the liquid inlet channel is the pipe of the liquid inlet pipe, the one-way valve is fixedly arranged in the liquid inlet pipe, the liquid outlet channel is formed between the outer wall of the liquid inlet pipe and the inner wall of the connector, and the bag cover abuts against the upper end of the connector and the upper end of the liquid inlet pipe to form a seal. Through the design of the liquid inlet pipe, the liquid inlet channel becomes a separate channel, which ensures that the liquid inlet channel and the liquid outlet channel are independent of each other. The cooperation of the above-mentioned bag cover with the connector and the liquid inlet pipe ensures the sealing of the liquid outlet channel, which ensures that the filled liquid is not in contact with the air during the process of being transferred from the filling machine to the bag body, thereby ensuring the freshness of the packed beverage.

[0009] In the beverage packaging bag, the inner top surface of the bag cover has a downward protruding and annular protruding ring part one, the upper end of the liquid inlet pipe is tightly matched with the protruding ring part one and forms a seal; the inner top surface of the bag cover also has a downward protruding and annular protruding ring part two, the upper end of the connector is tightly matched with the protruding ring part two and forms a seal. Through the design of the protruding ring part one and the protruding ring part two, the sealing performance between the bag cover and the connector and the liquid inlet pipe can be further improved, which is beneficial to further improve the air isolation performance of the packaging bag, thereby prolonging the preservation time of the beverage in the bag, and further improving the freshness of the beverage in the bag when being drunk.

[0010] In the beverage packaging bag, the filling port is arranged at the top of the bag cover and opposite to the inlet of the one-way valve. Through the above design, the filling head is more easily to find the opening of the one-way valve after entering the filling port, so that the filling head improves the filling speed.

[0011] In the beverage packaging bag, the edge of the filling port is provided with a plurality of circumferentially uniformly arranged connecting notches, which are used for butt joint with the filling head of the filling machine. Through the design of the connecting notches, the butt joint of the filling head is more convenient, thereby improving the speed of the filling operation.

[0012] In the beverage packaging bag, the inner wall of the connector has a partition part, the middle of the partition part is provided with a mounting through hole, the liquid inlet pipe is arranged in the mounting through hole and is sealingly fixed with the inner wall of the mounting through hole, the liquid outlet channel includes a strip-shaped liquid outlet hole for liquid to flow out to the outside, and the liquid outlet hole is arranged on the partition part and located on one side of the mounting through hole. The liquid outlet hole is the outlet of the liquid outlet channel. Since the upper part of the liquid inlet pipe needs to be closed by the bag cover and then butt joint with the filling head, through the design of the mounting position of the liquid inlet pipe and the opening position of the liquid outlet hole, the upper part of the liquid inlet pipe in the middle position has more available space and is not easily limited by the bag cover, which is beneficial to the subsequent butt joint of the filling head and improves the filling operation speed. In addition, the strip-shaped liquid outlet hole can ensure smooth liquid flow and will not cause sealing problems due to the too large flow diameter.

[0013] In the beverage packaging bag, the outer wall of the liquid inlet pipe is provided with an annular clamping groove, and the edge of the mounting through hole is clamped in the annular clamping groove and forms a seal therebetween. Through the design of the annular clamping groove, the connection reliability between the liquid inlet pipe and the connector is better, thereby improving the sealing performance of the connection between the liquid inlet pipe and the connector, further improving the isolation performance of the packaging bag, and improving the freshness of the beverage in the bag when being drunk.

[0014] In the beverage packaging bag, the liquid inlet pipe comprises a cylindrical section and a funnel section, and the one-way valve is arranged in the cylindrical section. When filling the beverage which is easy to generate foam, such as beer, the design of the funnel section can slow down the generation of foam, so that the filling speed of the liquid can be increased to a certain extent, thereby facilitating the improvement of the filling speed.

[0015] In the beverage packaging bag, the lower end of the liquid inlet pipe is fixedly connected with a rubber tube, and the free end of the rubber tube extends to the bottom of the bag body. Through the above design, the filling liquid is introduced into the bottom of the bag body by the rubber tube, so that the liquid is not easy to generate foam after being filled into the bag body, thereby facilitating the improvement of the filling speed of the liquid.

[0016] In the beverage packaging bag, an anti-theft ring is arranged between the bag cover and the joint, the anti-theft ring is connected with the bag cover through a connecting rib, the upper end edge of the anti-theft ring is provided with a plurality of upper clamping teeth, the lower end edge of the bag cover is provided with upper clamping blocks corresponding to the upper clamping teeth, the upper clamping teeth and the upper clamping blocks cooperate to prevent the anti-theft ring from rotating clockwise relative to the bag cover, the inner circumferential surface of the anti-theft ring is provided with inner clamping teeth, and the outer circumferential surface of the joint is provided with inner clamping blocks corresponding to the inner clamping teeth, the inner clamping blocks and the inner clamping teeth cooperate to prevent the anti-theft ring from rotating counterclockwise relative to the joint. Through the above design of the anti-theft ring, once someone tries to unscrew the bag cover counterclockwise, the connecting rib will be broken, so that it can be determined whether the packaging bag has been opened; at the same time, the anti-theft ring also improves the connection reliability between the bag cover and the joint to a certain extent, which is beneficial to improve the sealing performance of the bag cover and further improve the preservation effect of the packaging bag.

[0017] Compared with the prior art, the beverage packaging bag has the following advantages: when the beverage packaging bag is used to fill liquid beverage, the bag cover does not need to be disassembled, and the filling liquid is not in contact with the outside air during the whole filling process, so that the freshness of the packed beverage is well guaranteed, and the drinking requirements of the user can be well met; at the same time, the filling operation speed is fast, the waiting time of the user is saved, and the user experience is well improved.
