Technical Field

[0001] This utility model relates to the field of packaging container technology, and in particular to a suction nozzle for an easy-to-open anti-theft device. Background Technology

[0002] Flexible packaging bags used to hold beverages and jelly foods are usually equipped with a spout that connects to the inside of the flexible packaging for easy consumption. The slender structure of the spout allows the contents to flow out as needed, avoiding the problem of excessive spillage that occurs when pouring from traditional large-mouthed containers.

[0003] Existing anti-theft designs for mouthpieces are typically difficult to open. To prevent unauthorized opening during transportation, storage, or sales, an anti-theft ring is usually installed between the mouthpiece and the cap. However, such structures often require considerable opening force, especially for children, the elderly, or users with weak hand strength. This can easily lead to difficulty in unscrewing or incomplete breakage of the anti-theft ring, which not only affects the user experience but may also cause mouthpiece deformation or spillage due to forced opening, thus reducing the mouthpiece's practicality.

[0005] Therefore, the problem that this utility model aims to solve is that the anti-theft structure design of the existing nozzle is usually difficult to open. In order to prevent the product from being opened without authorization during transportation, storage or sales, an anti-theft ring locking structure is usually set between the nozzle and the cap. However, such structures often require a large opening force, especially for children, the elderly or users with weak hand strength, which can easily lead to difficulty in unscrewing and incomplete breakage of the anti-theft ring. This not only affects the user experience, but may also cause the nozzle to deform or the contents to spill due to forced opening, reducing the practicality of the nozzle.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0034] Example 1

[0035] Reference Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides a suction nozzle for an easy-to-open anti-theft device. The suction nozzle of the easy-to-open anti-theft device includes a suction nozzle tube assembly 1 and a tube cover assembly 2. The limiting ribs 21-4 can limit the assembly position of the first cover body 21 and the tube 11, which enhances the stability when the first cover body is screwed on and avoids displacement during the screwing process. The limiting block 24 can further limit the screwing stroke of the first cover body 21 to prevent excessive tightening that would make it difficult to open. The anti-theft piece 23 connected by the connecting rib 25 cooperates with the anti-theft ring buckle 11-5 of the tube 11. Under the premise of ensuring the anti-theft function, the structural design of the connecting rib 25 makes the anti-theft piece 23 easier to break and break completely when opened, which is especially convenient for children, the elderly or users with weak hand strength to open easily, thus improving the user experience.

[0036] Specifically, the mouthpiece assembly 1 includes a mouthpiece 11, the upper surface of which is fixed with a mouthpiece locking thread 11-1, and the inner wall of the mouthpiece 11 is provided with an anti-theft ring buckle 11-5.

[0037] Specifically, the mouth tube cover assembly 2 is disposed on the top of the mouth tube 11, including a first cover body 21 disposed on the top of the mouth tube 11, a limit block 24 disposed inside the first cover body 21, a connecting rib 25 fixed on the surface of the first cover body 21, and an anti-theft plate 23 fixed on the surface of the connecting rib 25.

[0038] Example 2

[0039] Reference Figures 2 to 10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the top of the nozzle 11 is provided with a first sealing surface 11-2, the inside of the first sealing surface 11-2 is provided with a second sealing surface 11-3, and the top of the first sealing surface 11-2 is provided with a third sealing surface 11-4.

[0041] A first tube buckle 11-7 is provided on one side of the tube 11, and a second tube buckle 11-6 is provided on the other side of the tube 11, which is adapted to the tube 11.

[0042] The bottom of the nozzle 11 is provided with an auxiliary block 13, including a welding groove 13-1 provided on the surface of the auxiliary block 13. The surface of the auxiliary block 13 is provided with weight reduction holes 13-2, and the number of weight reduction holes 13-2 is several.

[0043] With the locking thread 11-1 on the mouthpiece and the locking thread 22 on the mouthpiece cover, the mouthpiece 11 and the first cover 21 are tightly fixed together, preventing the first cover 21 from accidentally falling off due to bumps or external pressure during transportation, storage or normal use. At the same time, the threaded connection has higher connection strength than other simple fastening methods, which can effectively avoid the problem of loosening during frequent opening and closing, and extend the service life of the nozzle.

[0044] With the third sealing surface 11-4 in place, it fits tightly with the third sealing rib 21-3. When the nozzle is closed, it works with the first sealing surface 11-2 and the second sealing surface 11-3 to seal the nozzle, effectively blocking external environmental factors from affecting the inside of the packaging. At the same time, it ensures the integrity of the contents during storage and transportation, reducing the risk of product loss and environmental pollution caused by leakage.

[0045] The inner wall of the first cover 21 is fixed with a first sealing rib 21-1, which is distributed in a circumferential array.

[0046] The top of the inner wall of the first cover 21 is fixed with a second sealing rib 21-2, which cooperates with the upper end of the mouth tube 11.

[0047] The top of the inner wall of the first cover 21 is fixed with a third sealing rib 21-3, which is located outside the second sealing rib 21-2 and cooperates with the upper end of the mouth tube 11.

[0048] The inner wall of the first cover 21 is fixed with limiting ribs 21-4, and the number of limiting ribs 21-4 is several.

[0049] The first cover body 21 is provided with a tube cover locking thread 22 inside.

[0050] A connecting block 12 is fixed to the outer ring of the nozzle 11.

[0051] The anti-theft ring buckle 11-5 works in conjunction with the anti-theft plate 23 to achieve the anti-theft function. When the product is not opened, the anti-theft plate 23 is connected to the first cover 21 through the connecting rib 25 and is locked on the anti-theft ring buckle 11-5 to form a locking structure. When the user tries to open the nozzle, he needs to overcome a certain resistance, which causes the anti-theft plate 23 to separate from the anti-theft ring buckle 11-5. This process will cause the anti-theft plate 23 and the connecting rib 25 to break or deform, thus leaving obvious opening marks.

[0052] With the second tube clip 11-6 and the first tube clip 11-7 adapted to the tube 11, they can be used to connect with flexible packaging bags or other connecting parts. The clips enable a quick and secure connection. The connecting block 12 is mainly used to strengthen the connection between the tube 11 and other parts. It can serve as a connection fulcrum for a more secure connection with flexible packaging bags or other external structures.

[0053] By setting the welding groove 13-1, welding material is filled into the welding groove 13-1. Through the welding process, the mouth tube can be firmly connected with other components, increasing the welding area and improving the strength and stability of the welding. This makes the connection between the mouth tube and other components tighter and effectively prevents leakage or separation problems caused by weak welding. By setting the weight reduction hole 13-2, the weight of the mouth tube 11 is effectively reduced. The lighter mouth tube 11 is more convenient to use, easier for consumers to hold and operate, and improves the user experience.

[0054] The third sealing rib 21-3, together with the first sealing rib 21-1 and the second sealing rib 21-2, forms a sealing system. The third sealing rib 21-3 further strengthens the seal on the top of the nozzle, effectively blocking the intrusion of external air and impurities, while preventing the leakage of internal contents.

[0055] With the setting of the limiting rib 21-4, when the first cover 21 is screwed onto the mouth tube 11, the limiting rib 21-4 interacts with the outer wall of the mouth tube 11 to limit the screwing position of the first cover 21 on the mouth tube 11, ensuring that the degree of tightening of the first cover 21 is consistent each time, thereby ensuring the stability of the sealing effect. At the same time, the limiting rib 21-4 can also prevent the first cover 21 from being over-tightened, avoiding damage to the mouth tube 11 or the first cover 21 due to over-tightening, extending the service life of the nozzle, making it easier for users to control the degree of tightening, and improving the convenience of use.

[0056] The anti-theft plate 23 works in conjunction with the anti-theft ring buckle 11-5 on the inner wall of the tube 11 to achieve the anti-theft function. When the product is not opened, the anti-theft plate 23 is locked on the anti-theft ring buckle 11-5, forming a locked state, which effectively prevents the product from being maliciously opened or tampered with before it is sold.

[0057] Example 3

[0058] Reference Figures 1-4 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0059] Specifically, the nozzle cap assembly 2 also includes a second cap body 26, a third cap body 27, and a fourth cap body 28, wherein the second cap body 26, the third cap body 27, and the fourth cap body 28 are equivalent replacements for the first cap body 21, and the nozzle cap locking thread 22, the anti-theft plate 23, the limiting block 24, and the connecting rib 25 are installed on the second cap body 26, the third cap body 27, and the fourth cap body 28 in the same way as described in Embodiment 1 and Embodiment 2 above.

[0060] In use, the first sealing rib 21-1, the second sealing rib 21-2, and the third sealing rib 21-3 on the inner wall of the first cover 21 correspond to and are adapted to the first sealing surface 11-2, the second sealing surface 11-3, and the third sealing surface 11-4 of the mouth tube 11, respectively, forming a multi-seal structure. This significantly improves the sealing performance of the nozzle and effectively prevents the contents from spilling. The limiting rib 21-4 can precisely limit the assembly position of the first cover 21 and the mouth tube 11, ensuring accurate alignment between the sealing rib and the sealing surface. At the same time, it enhances the stability of the first cover when screwed on, preventing deviation during the screwing process. The limiting block 24 can further limit the screwing stroke of the first cover 21, preventing over-tightening that would cause difficulty in opening, and also preventing incomplete screwing that would affect the sealing performance.

[0061] The anti-theft plate 23 connected by the connecting rib 25 cooperates with the anti-theft ring buckle 11-5 of the mouth tube 11. Under the premise of ensuring the anti-theft function, the structural design of the connecting rib 25 makes the anti-theft plate 23 easier and more complete to break when opened. This not only prevents the product from being opened without authorization during transportation, storage or sales, but also avoids the problem of incomplete breakage of traditional anti-theft rings. It is especially convenient for children, the elderly or users with weak hand strength to open easily, improving the user experience. At the same time, the combination of multiple structures ensures the structural stability of the nozzle during opening and use, reduces the problem of nozzle deformation caused by forced opening, and greatly improves the practicality of the nozzle.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
