Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and in particular to a flexible tube flip-top structure and a packaging flexible tube. Background Technology

[0002] Existing packaging tubes can be mainly divided into two types according to their opening method: screw cap and flip cap. For flip cap packaging tubes, the flip structure typically consists of a cap base, a cap body, and a flexible connector. The cap base and cap body are connected by the flexible connector to achieve a relative flip-open function. In existing flip structure designs, the cap base, cap body, and flexible connector are usually manufactured as a single piece, made of the same material. To improve the durability of the flip structure, especially the fatigue resistance of the flexible connector, and to prevent breakage due to frequent flipping, high-strength materials are usually chosen for the one-piece molding. However, high-strength materials are also more expensive, leading to an increase in the overall cost of the flip structure. Conversely, if lower-cost materials are used, although the cost is reduced, the strength and durability of the flexible connector are difficult to guarantee, making it prone to breakage.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A flexible hose flip-top structure includes a cover 100, a cover body 200, and a connector 300. The cover 100 is provided with a discharge hole 101, and the cover body 200 is provided with a sealing post 210 corresponding to the discharge hole 101. The sealing post 210 is used to close the discharge hole 101. The connector 300 is provided with a flexible connecting part 310. The connector 300 and the cover 100 and / or the cover body 200 are separate structures. The cover body 200 and the cover 100 are connected by the connector 300 and can be flipped open and closed relative to each other through the flexible connecting part 310.

[0035] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, in use, the cover 200 and the cover base 100 are connected by a connector 300 and can be flipped open and closed relative to each other via a flexible connecting part 310. When it is necessary to close the flip-top structure, the cover 200 flips relative to the cover base 100. Figure 1 The indicated state causes the sealing post 210 to close the discharge port 101, preventing material from being discharged from the hose through the discharge port; when it is necessary to open the flip-top structure, the cover 200 flips relative to the cover seat 100. Figure 4In the indicated state, the sealing post 210 is disengaged from the discharge port 101, allowing the discharge port 101 to open and the material inside the hose to be discharged and used. Since the connector 300 and the cover 100 and / or cover 200 are separate structures, this design allows the flexible connector 310 to be made of a different material than the cover 100 and / or cover 200 during production. The flexible connector 310 can be made of a high-strength material for better durability, while the cover 100 and / or cover 200 can be made of a lower-cost material. This approach balances durability with cost reduction, facilitating production and application.

[0036] In practical applications, the specific structures of the cover base 100, the cover body 200, and the connector 300 can be set according to actual usage needs. The specific connection method between the connector 300 and the cover base 100 and / or the cover body 200 will not be described in detail here, but will be explained in detail below.

[0037] In some embodiments, the connector 300 and the cover 100 are separate structures, while the connector 300 and the cover 200 are an integral structure. It is understood that, as Figure 2 , Figure 3 and Figure 5 As shown, the connector 300 and the cover 100 are separate structures, while the connector 300 and the cover 200 are integral structures. During production, the connector 300 and the cover 200 can be integrally injection molded, and then the connector 300 is connected to the cover 100, thereby realizing the connection between the cover 100 and the cover 200 through the connector 300. Its structure is simple and easy to use.

[0038] In some embodiments, the connector 300 and the cover 200 are separate structures, while the connector 300 and the cover seat 100 are integral structures. It is understood that, in addition to the embodiments illustrated in the figures, the connector 300 and the cover 200 can also be designed as separate structures, while the connector 300 and the cover seat 100 are integral structures. During production, the connector 300 and the cover seat 100 can be integrally injection molded, and then the connector 300 and the cover 200 are connected, thereby achieving a connection between the cover seat 100 and the cover 200 via the connector 300.

[0039] In practical applications, in addition to the two embodiments described above, the connector 300, the cover base 100, and the cover body 200 can also be designed as separate structures. During production, the connector 300, the cover base 100, and the cover body 200 are prepared separately, and then the connector 300 is connected to the cover base 100 and the cover body 200 respectively by assembly, so that the cover base 100 and the cover body 200 are connected by the connector 300. The specific design can be set according to the actual use needs.

[0040] In some embodiments, the connector 300 is detachably connected to the cover 100. It is understood that, as Figure 2 , Figure 3 and Figure 5 As shown, by setting the connector 300 and the cover 100 to be detachable, the connector 300 and the cover 200 can be disassembled and replaced after prolonged use of the flip structure, thereby increasing the service life of the flip structure and facilitating its use. In practical applications, in addition to the detachable connection, the connector 300 and the cover 100 can also be connected and fixed by non-detachable methods such as bonding or heat fusion, depending on the actual usage requirements.

[0041] In some embodiments, the connector 300 is provided with a plug-in portion 320, and the side of the cover 100 is correspondingly provided with a slot 102 for the plug-in portion 320 to be inserted. It is understood that, as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in use, the connector 300 achieves a detachable connection between the connector 300 and the cover 100 by inserting the plug portion 320 into the slot 102 of the cover 100. Its structure is simple and easy to use. In practical applications, the plug portion 320 and the slot 102 can be an interference fit to increase the stability of the connection. Alternatively, the detachable connection between the connector 300 and the cover 100 can also be achieved through a threaded engagement structure or other connecting components, depending on the specific application requirements.

[0042] In some embodiments, the connector 300 is provided with an abutment step 330, and when the insertion portion 320 is inserted into the slot 102, the abutment step 330 abuts against the cover 100. It is understood that, as Figure 3 , Figure 5 and Figure 6 As shown, during use, the insertion part 320 is inserted into the slot 102, and the connector 300 abuts against the cover 100 via the abutment step 330, thereby restricting its insertion position into the slot 102, which facilitates proper engagement and ease of use. In practical applications, the specific structure of the abutment step 330 can be set according to actual usage requirements.

[0043] In some embodiments, the slot 102 extends longitudinally through the slot, and the insertion part 320 can be inserted into the slot 102 longitudinally. The lower side of the insertion part 320 is provided with a hook part 340. When the insertion part 320 is inserted into the slot 102, the hook part 340 can be engaged at the lower wall edge of the slot 102.

[0044] Understandably, such as Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the slot 102 extends longitudinally through the entire length. A hook portion 340 is provided on the lower side of the insertion part 320. In use, the insertion part 320 is inserted into the slot 102 from top to bottom. The hook portion 340 engages with the lower edge of the wall of the slot 102, thereby restricting the insertion part 320 from moving upwards relative to the slot 102 and preventing separation of the insertion part 320 from the slot 102. This ensures a stable and reliable connection and facilitates use. In practical applications, in addition to the above structure, a locking hole can be provided on either the wall of the slot 102 or the side wall of the insertion part 320. Correspondingly, a locking protrusion that mates with the locking hole can be provided on the other side, allowing both to engage and lock simultaneously, thus improving connection stability. The specific configuration can be tailored to the actual usage requirements.

[0045] In some embodiments, one of the wall portion on the lower side of the slot 102 and the hook portion 340 is provided with a limiting protrusion 341, and the other is provided with a limiting notch 103 that cooperates with the limiting protrusion 341.

[0046] Understandably, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a limiting protrusion 341 is provided on the hook portion 340, and a limiting notch 103 is correspondingly provided on the lower wall of the slot 102. When the hook portion 340 is engaged at the edge of the lower wall of the slot 102, the limiting protrusion 341 and the limiting notch 103 cooperate to limit the rotation or displacement of the insertion portion 320 in the slot 102, further improving the stability of the connection and facilitating use. In practical applications, the limiting protrusion 341 can also be provided on the lower wall of the slot 102, and the limiting notch 103 can be correspondingly provided on the hook portion 340. The specific setting can be adjusted according to actual usage needs.

[0047] In some embodiments, the cover 100 and / or the cover 200 are provided with a clearance recess 201, which is provided at the mating position when the cover 100 and the cover 200 are engaged.

[0048] Understandably, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the cover base 100 and the cover body 200 are provided with clearance recesses 201. These clearance recesses 201 are located at the mating positions when the cover base 100 and the cover body 200 are engaged, allowing the user's fingers to be inserted. The user's fingers can then be positioned in the clearance recesses 201 and apply force to flip the cover body 200 relative to the cover base 100, facilitating user operation and opening. In practical applications, the clearance recesses 201 can be provided only on the cover base 100 or only on the cover body 200; their specific structure and distribution can be set according to actual usage needs.

[0049] The packaging tube according to a second aspect of the present invention includes a tube flap structure according to the first aspect of the present invention described above.

[0050] According to the embodiments of the present utility model, the packaging tube adopts the above-mentioned tube flip-top structure, which helps to achieve better durability of the flip-top part, and while taking into account durability, it helps to reduce the overall cost of the flip-top structure, thereby reducing the cost of the packaging tube and facilitating production and application.

[0051] Since other components of the packaging tube of this utility model embodiment are known to those skilled in the art, they will not be described in detail here.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
