Description

Technical Field

[0001] This utility model relates to the field of mouthpiece technology, and in particular to a novel mouthpiece for mouthpiece bags. Background Technology

[0002] The spout head is the key functional component of a spout pouch. It is mostly made of food-grade PE, PP and other safe plastics. The structural design takes into account both sealing reliability and ease of use. It can be firmly fitted and sealed to the spout pouch body, making it convenient for quantitative dispensing of various materials such as liquids, pastes, and granules. At the same time, it can effectively block air and moisture to extend the product's shelf life. It is widely used in various packaging fields such as beverages, sauces, daily chemicals, and pet food.

[0003] The existing nozzle head is a regular cylinder with multiple ring buckles that connect to the outer cover. When packaging materials such as pastes or sauces, aluminum foil needs to be covered on top of the nozzle head to ensure a seal. However, after the outer cover is installed, the buckles on the top of the inner wall of the outer cover will enter the interior of the nozzle head, causing creases or tears to the aluminum foil on the nozzle head, affecting the sealing effect. If the buckles inside the outer cover are stuck at the edge of the aluminum foil, although they will not tear the aluminum foil, when the aluminum foil is torn open and the outer cover is put back on, the sealing effect is poor because the buckles cover the edge of the nozzle head. Therefore, we propose a new type of nozzle head for nozzle bags. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a novel mouthpiece head for mouthpiece bags.

[0005] This utility model is achieved by the following technical solution: a novel mouthpiece head for a mouthpiece bag, comprising a mouthpiece assembly and a sealing assembly, wherein the sealing assembly is located above the mouthpiece assembly; The nozzle assembly includes a base, a hollow column is fixedly connected to the top of the base, the surface of the hollow column is provided with external threads, an extension is fixedly connected to the top of the hollow column, a sealing part is provided at the top of the extension, and a groove is provided between the hollow column and the extension.

[0006] The above technical solution ensures a tight seal after connection through the multiple external threads on the hollow column, and the groove facilitates the insertion of the plug part in the sealing component to achieve a tight fit and improve the sealing effect.

[0007] As a further improvement to the above solution, the base, hollow column, external thread, extension and sealing part are injection molded as a single piece.

[0008] The above technical solution simplifies the production process and improves product consistency through the one-piece molded nozzle assembly.

[0009] As a further improvement to the above solution, the diameter of the extension is larger than the diameter of the sealing portion.

[0010] By using the above technical solution, aluminum foil is covered on the sealing part during production, which can prevent fluid leakage through the extension part.

[0011] As a further improvement to the above solution, the sealing assembly includes an outer cover, an inner cover fixedly connected to the top of the inner wall of the outer cover, a connecting part provided at the lower end of the inner cover, an internal thread provided on the inner wall of the connecting part, and an insertion part provided inside the inner cover.

[0012] Through the above technical solution, the outer surface of the outer cover is provided with anti-slip texture, which facilitates the tightening operation during use. The inner cover, connecting part and plug part are injection molded as one piece, which simplifies the production and processing process and ensures the consistency of the product.

[0013] As a further improvement to the above solution, the top of the inner cover has a conical structure, and the diameter of the connecting part is larger than the diameter of the sealing part.

[0014] Through the above technical solution, the use of materials on the inner cover of the conical structure can be reduced, thus lowering production costs. Since the diameter of the connecting part is larger than that of the sealing part, when the sealing component and the nozzle component are assembled, the insertion part does not contact the aluminum foil on the sealing part, thus avoiding creases or tears in the aluminum foil.

[0015] As a further improvement to the above solution, the inner wall of the internal thread is threadedly connected to the surface of the external thread.

[0016] The above technical solution provides a strong seal, effectively preventing fluid leakage from gaps, and allows for smooth operation, making it easy for users to repeatedly open and close the connection.

[0017] As a further improvement to the above solution, the lower end of the insertion part extends into the interior of the groove.

[0018] Through the above technical solution, a seal is formed when the insertion part enters the groove. The insertion seal is added on the basis of the thread seal, forming double protection, thereby improving the overall sealing effect.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets up a suction nozzle assembly and a sealing assembly. Specifically, when sealing the suction nozzle assembly, the outer cover is placed over the hollow column, and then the outer cover is rotated so that the internal thread of the inner wall of the connecting part is threadedly connected with the external thread, which plays a preliminary sealing role. During the tightening process, the insertion part moves downward and inserts into the inside of the groove, which fits tightly with the groove, sealing the extension part again and preventing fluid from leaking through the extension part, thus playing a secondary sealing role. This ensures that a good sealing effect can still be maintained after the aluminum foil is torn open.

[0020] This invention features a plug-in portion, specifically one whose diameter is larger than that of the sealing portion. This prevents the plug-in portion from contacting the aluminum foil on the sealing portion during assembly of the sealing component and the nozzle component, thus avoiding creases or tears in the aluminum foil and ensuring a good sealing effect.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0024] Please combine Figure 1-5 A novel mouthpiece for a mouthpiece bag according to this embodiment includes a mouthpiece assembly 1 and a sealing assembly 2, with the sealing assembly 2 located above the mouthpiece assembly 1; The nozzle assembly 1 includes a base 101, a hollow column 102 fixedly connected to the top of the base 101, an external thread 103 provided on the surface of the hollow column 102, an extension 104 fixedly connected to the top of the hollow column 102, a sealing part 105 provided on the top of the extension 104, and a groove 106 provided between the hollow column 102 and the extension 104. The external thread 103 on the surface of the hollow column 102 facilitates connection with the sealing assembly 2. Fluid can flow outward through the hollow column 102, and the groove 106 between the hollow column 102 and the extension 104 allows for secondary sealing.

[0025] The base 101, hollow column 102, external thread 103, extension 104 and sealing part 105 are injection molded as one piece.

[0026] The diameter of the extension 104 is larger than the diameter of the sealing part 105.

[0027] The sealing assembly 2 includes an outer cover 201, an inner cover 202 fixedly connected to the top of the inner wall of the outer cover 201, a connecting part 203 provided at the lower end of the inner cover 202, an internal thread 204 provided on the inner wall of the connecting part 203, and an insertion part 205 provided inside the inner cover 202. When the nozzle assembly 1 needs to be sealed, the outer cover 201 is placed over the hollow column 102, and then the outer cover 201 is rotated so that the internal thread 204 on the inner wall of the connecting part 203 is threadedly connected to the external thread 103, which plays a preliminary sealing role. During the tightening process, the insertion part 205 will move downward and insert into the inside of the groove 106, and fit tightly with the groove 106, sealing the extension part 104 again to prevent fluid from leaking through the extension part 104, playing a secondary sealing role, so that a good sealing effect can still be guaranteed after the aluminum foil is torn.

[0028] The top of the inner cover 202 has a conical structure, and the diameter of the connecting part 203 is larger than the diameter of the sealing part 105. Since the diameter of the connecting part 205 is larger than the diameter of the sealing part 105, when the sealing assembly 2 is assembled with the nozzle assembly 1, the connecting part 205 does not contact the aluminum foil on the sealing part 105, thus avoiding creases or tears in the aluminum foil and ensuring the sealing effect.

[0029] The inner wall of the internal thread 204 is threaded to the surface of the external thread 103. The mating of the internal thread 204 and the external thread 103 ensures a sealing effect while facilitating operation.

[0030] The lower end of the insertion part 205 extends into the interior of the groove 106.

[0031] The implementation principle of the novel suction head for a suction bag in this application embodiment is as follows: During production, aluminum foil is covered on the sealing part 105 to seal the suction assembly 1. Since the diameter of the insertion part 205 is larger than the diameter of the sealing part 105, the insertion part 205 does not contact the aluminum foil on the sealing part 105 when the sealing assembly 2 is assembled with the suction assembly 1, thus avoiding creases or tears in the aluminum foil and ensuring the sealing effect. When in use, after tearing off the aluminum foil on the sealing part 105, when it is necessary to seal the suction assembly 1, the outer cover 201 is covered on the outside of the hollow column 102, and then the outer cover 201 is rotated so that the internal thread 204 on the inner wall of the connecting part 203 is threadedly connected with the external thread 103, which plays a preliminary sealing role. During the tightening process, the insertion part 205 will move downward and insert into the inside of the groove 106, and fit tightly with the groove 106, sealing the extension part 104 again to prevent fluid from leaking through the extension part 104, thus playing a secondary sealing role, so that a good sealing effect can still be guaranteed after the aluminum foil is torn off.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
