DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of the one-piece twist-off nozzle. Figure 2 It is a schematic diagram of the setting position of the breaking portion 103. The utility model provides a one-piece twist-off suction nozzle: it includes a suction nozzle body 100 and a matching component. The suction nozzle body 100 is symmetrically provided with a protective portion 101. The protective portion 101 is internally provided with a connecting portion 102 and a breaking portion 103. The protective portion 101 is provided with a flexible protective sheet 104 that can be torn and removed in an upward direction. The matching component includes a sealing film 105 and a protective cover 106. The above-mentioned solution can solve the problem of the suction nozzle and the sealing cover in the existing packaging bag being directly threaded together. After use, some unscrupulous vendors will refill and reseal the recycled genuine beverage packaging bags and push them back into the market to seek illegal profits. At the same time, there are also great safety hazards to the hygiene and safety of food. It is understandable that the above-mentioned solution can destroy the sealing structure between the suction nozzle body 100 and the packaging bag, that is, the packaging bag is directly connected to the outside world through the connecting portion 102, which makes it difficult to be refilled and used later.

[0021] In this embodiment, the nozzle body 100 is manufactured by injection molding.

[0022] Among them, protective parts 101 are symmetrically arranged on the nozzle body 100. A communication part 102 and a breaking part 103 are arranged inside the protective part 101. The communication parts 102 are symmetrically arranged and communicate with the internal flow channel of the nozzle body 100, and are of an L-shaped structure with the opening facing downward. The breaking part 103 is arranged at the bottom port of the communication part 102; after the nozzle body 100 is processed, the communication parts 102 are arranged on both sides of the strengthening part 108, and the breaking part 103 that can be easily broken by a certain force is arranged at the bottom port of the communication part 102. Then, the protective part 101 is melt-welded and arranged outside the communication part 102. The protective part 101 prevents the breaking part 103 from being externally impacted. When the operating cavity spacing of the protective part 101 is sufficient, the breaking part 103 can be pinched and broken by fingers. When the spacing is small, it can be broken by directly pushing with the cooperation of external tools. The protective part 101 is made of hard plastic structure.

[0023] A flexible protective sheet 104 that can be torn off upward is arranged on the protective part 101; the flexible protective sheet 104 is of a Z-shaped structure and can be torn off with a certain force, so that the breaking part 103 is exposed.

[0024] The sealing film 105 is arranged on the port end face of the matching part 109 of the nozzle body 100. The protective cover 106 is threadedly connected to the strengthening part 108. The sealing film 105 is heat-pressed on the port of the matching part 109 for sealing, and the protective cover 106 is used for further protection.

[0025] Secondly, the nozzle body 100 is composed of a connecting part 107, the strengthening part 108 and the matching part 109. The connecting part 107 can be fixedly connected to the packaging bag; the strengthening part 108 is integrally formed with the connecting part 107 and communicates with each other, and is provided with an external thread end for threaded connection and cooperation with the protective cover 106. The communication parts 102 are arranged on both sides of the strengthening part 108; the matching part 109 is integrally formed with the strengthening part 108 and communicates with each other, and is located inside the abutting cylinder of the protective cover 106. The connecting part 107 can be integrally formed with the bag mouth of the packaging bag by hot melting during the processing of the packaging bag.

[0026] Then, an anti-slip part 110 is arranged on the outer side of the protective cover 106. This structure facilitates anti-slip when the protective cover 106 is rotated to be removed or installed. The protective cover 106 has a cylindrical structure inside. After the sealing film 105 is damaged, the inner bottom of the cylinder abuts against the port of the matching part 109 for sealing.

[0027] Furthermore, an unpenetrated connecting threaded hole 111 is arranged on the top end face of the protective cover 106. This structure facilitates the arrangement of the conical rod 112.

[0028] Finally, the conical rod 112 is threadedly connected to the reinforcement portion 108 and, after removal, can be threadedly connected to the connecting threaded hole 111 on the top of the protective cover 106. The conical rod 112 can be directly installed in the threaded hole on the reinforcement portion 108 when shipped from the factory. After installation, it is in a vertical position and does not affect the installation of the protective cover 106. During subsequent use, the protective cover 106 is removed, and then the conical rod 112 is removed and installed on top of the protective cover 106. Finally, the protective cover 106 can be held and the sharp part of the conical rod 112 can be used to pierce the sealing membrane 105 to destroy the sealing membrane 105.

[0029] The present invention solves the problem of direct threaded connection between the suction nozzle and the sealing cover in the existing packaging bag. After use, unscrupulous vendors refill and reseal the recycled genuine beverage packaging bags and push them into the market again to seek illegal profits. At the same time, there is a great safety hazard to the hygiene and safety of food. When using, the protective cover 106 is removed, and then the sealing film 105 is broken so that the liquid food inside the packaging bag can be discharged and eaten through the suction nozzle body 100. After the user has finished drinking, the flexible protective sheets 104 on both sides are torn off from bottom to top to expose the breaking part 103 inside the protective part 101, and then the breaking part 103 is twisted to open. 3, or use an external tool to push and squeeze the breaking portion 103 toward the side close to the reinforcing portion 108 to break it, or use a tool to clamp the breaking portion 103 from the bottom side to the top side and twist it. At this time, the sealing structure between the nozzle body 100 and the packaging bag is destroyed, that is, the packaging bag is directly connected to the outside through the connecting portion 102, and it is difficult to be refilled and used later. This can solve the problem of the suction nozzle and the sealing cover in the existing packaging bag being directly threaded together. After use, some unscrupulous vendors will refill and reseal the recycled genuine beverage packaging bags and push them into the market again, seeking illegal profits while posing a great safety hazard to food hygiene and safety.
