Description

Technical Field

[0001] This utility model belongs to the field of container bag technology, and in particular relates to a snap-on safety container bag. Background Technology

[0002] In existing container bag designs, such as common bagged beverage or daily chemical product packaging, the bag opening and cap are generally locked using a threaded screw-on locking method. This threaded connection structure can meet basic sealing requirements in stable everyday environments, and its operation is relatively simple. However, when these containers are used in more demanding or safety-critical scenarios, their limitations become apparent. For example, in long-distance logistics transportation, industrial production environments, or frequent movement scenarios, continuous vibration, impact, and bumps can easily cause slight relative displacement or loosening between the threads. Over time, this slight loosening can not only compromise the seal of the contents, causing leakage, contamination, or spoilage, but it can also cause the cap to accidentally detach, leading to serious property damage or environmental pollution risks.

[0003] Traditional threaded bag caps are significantly inadequate in preventing accidental opening, especially from children. Young children can easily open the bag by simply twisting it. This ease of opening poses a significant safety hazard when the bag contains potentially dangerous items such as medications, toxic chemicals, or alcoholic beverages. Accidental ingestion by a child could lead to poisoning, burns, or other irreversible health damage.

[0004] Therefore, there is an urgent need for a snap-on safety container bag that integrates additional security mechanisms. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a snap-on safety container bag that integrates a double locking mechanism on the basis of conventional threaded sealing. This effectively prevents accidental loosening and detachment during transportation and daily use, and significantly reduces the risk of children accidentally opening it, thus improving safety while maintaining ease of operation for adults.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A snap-lock safety container bag, comprising:

[0008] The bag body has an opening at its upper end;

[0009] A bag mouth fixed at the bag opening, the bag mouth including an outer mouth, the outer periphery of the outer mouth having a first thread, the lower end of the first thread having a buckle structure, the buckle structure including a locking buckle and an unlocking pressure plate connected to the locking buckle, the locking buckle having a first inclined surface on one side;

[0010] The bag cap has a second thread on its inner circumference that mates with the first thread, and a locking groove on its lower edge. When the bag cap is screwed onto the outer opening, the lower edge of the bag cap will deform by pressing the locking buckle through the first inclined surface and get stuck in the locking groove. The unlocking pressure plate is used to disengage the locking buckle from the locking groove.

[0011] Furthermore, the buckle structure includes a movable plate with a movable groove, and a movable piece extending from the movable plate in the movable groove, the locking fastener being attached to the upper surface of the end of the movable piece.

[0012] Furthermore, the unlocking pressure plate is formed on the movable plate. When the unlocking pressure plate is pressed down, the movable plate will deform to cause the locking buckle to move downward.

[0013] Optionally, a transverse protrusion is provided on the outer periphery of the lower edge of the bag cover, and a second inclined surface is provided on one side of the transverse protrusion. The locking groove is formed on the other side of the transverse protrusion away from the second inclined surface.

[0014] Furthermore, the buckle structure includes a support block extending laterally outward from the outer peripheral wall of the outer mouth, the unlocking pressure plate being vertically arranged and connected to the support block, and the locking buckle being disposed on the upper edge of the unlocking pressure plate. When the lower end of the unlocking pressure plate is pressed laterally, the locking buckle will shift outward and disengage from the locking groove.

[0015] Furthermore, the locking groove is a notch formed at the lower edge of the bag cap.

[0016] Furthermore, the buckle structure is provided on both opposite sides of the outer peripheral wall of the outer mouth.

[0017] Furthermore, the bag opening also includes a horizontally arranged partition plate, with the outer opening at the upper end of the partition plate and an inner interface at the lower end of the partition plate, the inner interface being used to fix it to the bag opening.

[0018] Furthermore, the inner interface is connected to a support tube that extends into the bag body, and the side wall of the support tube is provided with a groove.

[0019] Furthermore, the bag cap is provided with anti-slip texture.

[0020] The beneficial effects of this utility model are:

[0021] This invention features a buckle structure with a first bevel on the outer opening and a locking groove along the lower edge of the bag cap. When the bag cap is screwed in, the buckle structure automatically engages with the locking groove, forming a double lock that effectively prevents accidental loosening due to vibration. The opening process requires operating an unlocking plate to disengage the locking buckle from the locking groove before reverse rotation, significantly increasing the opening steps and difficulty, reducing the possibility of accidental opening by children, and improving safety. An movable groove with a locking buckle at the end of the movable plate allows for unlocking when the unlocking plate is pressed down. An unlocking plate with a support block on the outer opening allows for unlocking when the unlocking plate is pressed from the side. A support tube provides support to the inner wall of the bag, preventing collapse and blockage when the contents are poured out. This invention integrates a double locking mechanism on top of a conventional threaded seal, effectively preventing accidental loosening and detachment during transportation and daily use, significantly reducing the risk of accidental opening by children, and maintaining ease of operation for adults while improving safety.

[0034] See appendix Figure 1 To be continued Figure 7The figure shows a specific embodiment of the snap-on safety container bag provided by this utility model. Example 1:

[0035] See appendix Figure 1 and attached Figure 2 This embodiment provides a pressure-locking safety container bag, comprising:

[0036] Bag body 1, with a bag opening 110 at the upper end of bag body 1;

[0037] The bag mouth 2 is fixed at the bag opening 110. The bag mouth 2 includes an outer mouth 210. The outer periphery of the outer mouth 210 is provided with a first thread 211. The lower end of the first thread 211 is provided with a buckle structure 220. The buckle structure 220 includes a locking buckle 221 and an unlocking pressure plate 222 connected to the locking buckle 221. One side of the locking buckle 221 is provided with a first inclined surface 2211.

[0038] The bag cover 3 has a second thread 310 on its inner circumference that mates with the first thread 211. The lower edge of the bag cover 3 has a locking groove 320. When the bag cover 3 is screwed onto the outer opening 210, the lower edge of the bag cover 3 will be deformed by the first inclined surface 2211 pressing the locking buckle 221 and locking it into the locking groove 320. The unlocking plate 222 is used to disengage the locking buckle 221 from the locking groove 320.

[0039] See appendix Figure 3 and attached Figure 4 In the above embodiment, the first thread 211 on the outer opening 210 of the bag mouth 2 and the second thread 310 inside the bag cover 3 cooperate to achieve a first locking structure by clockwise screwing. When the bag cover 3 is screwed clockwise until the lower edge of the bag cover 3 presses against the locking buckle 221, the locking buckle 221 will deform. When screwed in place, that is, when the locking buckle 221 corresponds to the locking groove 320, the deformed locking buckle 221 will reset and spring back and automatically lock into the locking groove 320, realizing a second locking structure. This double locking structure, which combines a threaded structure and a locking structure, effectively prevents accidental loosening caused by vibration. Due to the presence of the first inclined surface 2211, no additional operation is required when tightening the bag cover 3; however, when it is necessary to unscrew the bag cover 3, the user needs to operate the unlocking pressure plate 222 to disengage the locking buckle 221 from the locking groove 320 before it can be rotated counterclockwise to open, significantly increasing the opening steps and difficulty, reducing the possibility of children accidentally opening it, and improving safety. The dual locking structure of this embodiment forms a two-step opening mechanism of "push + turn". Young children usually lack sufficient coordination and comprehension to complete the two actions of "pressing the unlocking plate 222" and "rotating the bottle cap" at the same time. This greatly increases the difficulty for children to open the bottle, effectively preventing accidental ingestion accidents and meeting international requirements for child-safe packaging (CR Packaging).

[0040] See appendix Figure 3 and attached Figure 4 In the above embodiment, the buckle structure 220 includes a movable plate 223, on which a movable groove 2231 is formed. A movable piece 2232 extends from the movable plate 223 within the movable groove 2231, and a locking buckle 221 is disposed on the upper surface of the end of the movable piece 2232. In this embodiment, the movable piece 2232 extends from the movable plate 223 within the movable groove 2231, allowing the movable piece 2232 to undergo the required elastic deformation based on the movable groove 2231, and to be compressed and deformed when the bag cap 3 is screwed onto the bag opening 2, ensuring that the locking buckle 221 can reliably engage with the locking groove 320.

[0041] See appendix Figure 3 and attached Figure 4 In the above embodiment, the unlocking pressure plate 222 is formed on the movable plate 223. When the unlocking pressure plate 222 is pressed down, the movable plate 223 will deform to cause the locking buckle 221 to move downward. In this embodiment, the unlocking pressure plate 222 is formed on the movable plate 223 and linked with the locking buckle 221, so that when the unlocking pressure plate 222 is pressed down, it can directly drive the movable plate 223 to deform, causing the locking buckle 221 to move down synchronously and disengage from the locking groove 320, making the operation intuitive and convenient. In this embodiment, the movable plate 223 and the partition plate 240 of the bag mouth 2 are on the same plane and integrally formed.

[0042] See appendix Figure 3 and attached Figure 4 In the above embodiment, a transverse protrusion 330 is provided on the outer periphery of the lower edge of the bag cap 3, and a second inclined surface 331 is provided on one side of the transverse protrusion 330. The locking groove 320 is formed on the other side of the transverse protrusion 330 away from the second inclined surface 331. In the embodiment, when the bag cap 3 is screwed on, the second inclined surface 331 of the transverse protrusion 330 at its lower edge can smoothly slide along the first inclined surface 2211 and squeeze the locking buckle 221 to deform, guiding the locking buckle 221 to finally engage with the locking groove 320. Example 2:

[0043] See appendix Figure 5 This embodiment provides a side-pressure snap-on safety container bag, comprising:

[0044] Bag body 1, with a bag opening 110 at the upper end of bag body 1;

[0045] The bag mouth 2 is fixed at the bag opening 110. The bag mouth 2 includes an outer mouth 210. The outer periphery of the outer mouth 210 is provided with a first thread 211. The lower end of the first thread 211 is provided with a buckle structure 220. The buckle structure 220 includes a locking buckle 221 and an unlocking pressure plate 222 connected to the locking buckle 221. One side of the locking buckle 221 is provided with a first inclined surface 2211.

[0046] The bag cover 3 has a second thread 310 on its inner circumference that mates with the first thread 211. The lower edge of the bag cover 3 has a locking groove 320. When the bag cover 3 is screwed onto the outer opening 210, the lower edge of the bag cover 3 will be deformed by the first inclined surface 2211 pressing the locking buckle 221 and locking it into the locking groove 320. The unlocking plate 222 is used to disengage the locking buckle 221 from the locking groove 320.

[0047] See appendix Figure 6 and attached Figure 7 In the above embodiment, the buckle structure 220 includes a support block 224 extending laterally outward from the outer peripheral wall of the outer opening 210. An unlocking pressure plate 222 is vertically arranged and connected to the support block 224. A locking buckle 221 is disposed on the upper edge of the unlocking pressure plate 222. When the lower end of the unlocking pressure plate 222 is pressed laterally, the locking buckle 221 will shift outward and disengage from the locking groove 320. In this embodiment, the support block 224 is connected to the inner center slightly above the unlocking pressure plate 222. When the lower end of the unlocking pressure plate 222 is pressed laterally, the locking buckle 221 on its upper edge can shift outward and disengage from the locking groove 320, thereby unlocking the bag cover 3. This embodiment provides a different unlocking operation method than the downward pressing method of Embodiment 1. Compared to the downward pressing method of Embodiment 1, the side-pressing method of this embodiment can reduce the occupation of lateral space to a certain extent.

[0048] See appendix Figure 6 and attached Figure 7 In the above embodiment, the locking groove 320 is a notch formed at the lower edge of the bag cap 3. Buckle structures 220 are provided on both opposite sides of the outer peripheral wall of the outer opening 210. In this embodiment, the notch-type locking groove 320 is easy to manufacture and can effectively accommodate the locking buckle 221 and limit its displacement, ensuring the locking effect. The buckle structures 220 provided on both sides achieve symmetrical two-point locking between the bag cap 3 and the bag opening 2, making the locking more balanced and secure, effectively resisting vibrations and impacts in all directions, and preventing the bag cap 2 from loosening. When unlocking, the user only needs to pinch the two unlocking pressure plates 222 with the thumb and forefinger of one hand and apply force to unlock the bag cap 3. At this time, the other hand can open the bag cap 3 by twisting it, making the unlocking and opening process more intuitive. Example 3:

[0049] This embodiment, based on embodiment 1 or embodiment 2, provides a snap-on safety container bag that is easier to assemble and use.

[0050] See appendix Figure 6In this embodiment, the bag spout 2 further includes a horizontally arranged partition plate 240. The upper end of the partition plate 240 is provided with an outer spout 210, and the lower end of the partition plate 240 is provided with an inner interface 230, which is used to fix it to the bag opening 110. In this embodiment, the entire bag spout 2 is a one-piece molded structure, and the inner interface 230 is fixed to the bag opening 110 to ensure reliable sealing and convenient assembly. In this embodiment, the inner interface 230 is connected to a support tube 4 that extends into the bag body 1. The side wall of the support tube 4 is provided with a groove 410 to support the inner wall of the bag body 1 and prevent the bag body 1 from collapsing and blocking when the contents are poured out. At the same time, the groove 410 is designed to facilitate the smooth flow of high-viscosity or particulate contents, making it convenient for users.

[0051] See appendix Figure 7 In the above embodiment, the bag cap 3 is provided with anti-slip texture 340. In this embodiment, the anti-slip texture 340 makes it easy for the user to apply force when turning the bag cap 3 to open or close, even when their hands are wet, thus improving the convenience and reliability of operation.

[0052] In summary, this embodiment provides a snap-on safety container bag. By providing a snap-on structure 220 with a first inclined surface 2211 on the outer opening 210 and a locking groove 320 along the lower edge of the bag lid 3, the snap-on structure 220 automatically engages with the locking groove 320 when the bag lid 3 is screwed into place, forming a double lock and effectively preventing accidental loosening due to vibration. The need to operate the unlocking plate 222 to disengage the locking buckle 221 from the locking groove 320 before it can be rotated in the opposite direction to open the bag significantly increases the opening steps and difficulty, reducing the possibility of children accidentally opening it and improving safety. Furthermore, by providing an active groove 2231 on the active plate 223... The movable piece 2232 with a locking buckle 221 at the end can be unlocked when the unlocking plate 222 is pressed down; the unlocking plate 222 with a support block 224 is set on the outer mouth 210, and the unlocking plate 222 can be unlocked when it is pressed from the side; the support tube 4 is set to support the inner wall of the bag body 1, preventing the bag body 1 from collapsing and blocking when the contents are poured out; this embodiment can integrate a double locking mechanism on the basis of conventional threaded seal, which can effectively prevent accidental loosening and falling off during transportation and daily use, and significantly reduce the risk of children accidentally opening it, improving safety while maintaining the convenience of adult operation.

[0053] The embodiments described above are merely one of the preferred embodiments of this utility model.
