Description

Technical Field

[0001] This invention relates to the field of bottle cap technology, specifically to a flip cap with a safety catch. Background Technology

[0002] Current flip-top bottle caps mostly employ external anti-theft designs (such as external tamper-evident rings), which are prone to dust accumulation and damage. This is especially problematic for high-value liquids (such as premium beverages and pharmaceuticals), where the risk of unauthorized opening leading to theft, substitution, or contamination is significant. While traditional tamper-evident rings are highly effective in screw-on caps, their integration with the flip-top mechanism is insufficient when applied to flip-top caps, failing to effectively prevent unauthorized opening. Furthermore, existing flip-top caps lack an internal liquid isolation mechanism, making repeated opening and closing susceptible to beverage oxidation and contamination. Utility Model Content

[0003] Therefore, one of the objectives of this utility model is to provide a flip cover with a safety plate to overcome the shortcomings and deficiencies of the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A flip cover with a safety catch includes an upper cover and a lower cover. One side of the upper cover is hinged to one side of the lower cover. The lower cover is connected to an anti-theft ring. Several disconnectable connection points are provided between the lower cover and the anti-theft ring. The upper cover is provided with a receiving groove, and a safety catch is fastened to the receiving groove. The safety catch includes an upper piece that fastens to the receiving groove and a lower piece that is connected to the upper piece by several connecting ribs and extends out of the receiving groove. The lower piece is provided with an elastic latch. The lower cover is provided with a limiting groove, and a limiting part is provided on the side wall of the limiting groove. When the upper cover is closed to the lower cover, the lower piece is inserted into the limiting groove, and the elastic latch engages with the limiting part. After the upper cover is flipped over and the connecting ribs break, the upper piece remains in the receiving groove, and the lower piece falls into the limiting groove.

[0006] Preferably, the upper piece is provided with a snap-fit ​​part, and the side wall of the receiving groove is provided with a protrusion, and the snap-fit ​​part is engaged with the protrusion.

[0007] Preferably, the lower cover is provided with a liquid outlet, and a check valve is provided at the liquid outlet, with a slit on the check valve.

[0008] Preferably, the cut is cross-shaped.

[0009] Preferably, the inner wall of the anti-theft ring is provided with a plurality of limiting blocks.

[0010] Preferably, the side wall of the lower cover is provided with a strip-shaped anti-slip groove in a ring shape.

[0011] Preferably, the inner wall of the lower cover is integrally formed with internal threads for flip-top assembly and disassembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. A dual anti-theft structure is set up with an anti-theft ring and a safety pin. The first layer of anti-theft structure is that if the connection point breaks, the anti-theft ring will remain at the bottle mouth, providing direct and irreversible evidence of the first opening, effectively preventing the product from being opened during circulation (before it is sold).

[0014] The first layer of anti-theft is the safety lock design, which is highly concealed and requires the connecting ribs to be broken to open, thus preventing the internal structure from being easily damaged or restored.

[0015] 2. The built-in second-layer anti-theft structure (safety plate locking design) provides a better seal between the top and bottom covers, effectively preventing external dust and contaminants from entering the flip cover.

[0016] 3. The design of the check valve and the cut-out allows the flip cap to seal the liquid outlet when closed, isolating air and preventing the contents of the bottle from oxidizing or becoming contaminated.

[0017] The slit can only be opened to allow the contents to flow out when pressure is applied to the bottle body, making it convenient and hygienic to use. Attached Figure Description

[0023] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5As shown, this utility model proposes a flip cover with a safety plate, including an upper cover 1 and a lower cover 2. One side of the upper cover 1 is hinged to one side of the lower cover 2. The lower cover 2 is connected to an anti-theft ring 6. Several disconnectable connection points 7 are provided between the lower cover 2 and the anti-theft ring 6. The upper cover 1 is provided with a receiving groove 3. A safety plate 5 is fastened to the receiving groove 3. The safety plate 5 includes an upper piece 51 that is fastened to the receiving groove 3 and a lower piece 53 that is connected to the upper piece 51 through several connecting ribs 52 and extends out of the receiving groove 3. The lower piece 53 is provided with an elastic latch 54. The lower cover 2 is provided with a limiting groove 4. The side wall of the limiting groove 4 is provided with a limiting part 41. When the upper cover 1 is closed on the lower cover 2, the lower piece 53 is inserted into the limiting groove 4, and the elastic latch 54 is engaged with the limiting part 41. After the upper cover 1 is flipped over and the connecting ribs 52 are broken, the upper piece 51 remains in the receiving groove 3, and the lower piece 53 falls into the limiting groove 4.

[0025] The above design creates a two-layer anti-theft structure on the flip cover:

[0026] The first layer of anti-theft structure is the anti-theft at the connection between the flip cap and the bottle mouth. When the flip cap is unscrewed from the bottle mouth, the connection point 7 breaks, causing the anti-theft ring 6 to detach from the lower cap 2 and remain at the bottle mouth, forming an irreversible separation state. This allows sellers and consumers to directly determine whether the product has been illegally opened or replaced by observing the separation of the anti-theft ring 6, effectively preventing the product from being used in advance before it is sold or the outer cap from being maliciously replaced.

[0027] The second layer of anti-theft structure is the anti-theft mechanism between the upper cover 1 and the lower cover 2, with a locking piece 5 securing them together. Opening the cover requires flipping the upper cover 1, causing the connecting rib 52 to break, thus separating the upper piece 51 and the lower piece 53 and releasing the lock. This structure is built into the flip cover, providing better anti-theft performance and improved sealing, effectively preventing external dust and contaminants from entering the flip cover. After the connecting rib 52 breaks, the upper piece 51 remains in the receiving groove 3, while the lower piece 53 falls into the limiting groove 4, facilitating collection and disposal, making it more environmentally friendly and conducive to recycling.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, the upper piece 51 is provided with a snap-fit ​​part 55, and the side wall of the receiving groove 3 is provided with a protrusion 31. The snap-fit ​​part 55 is fastened to the protrusion 31. In practical applications, other fixed connection methods such as mutual plugging can also be used.

[0029] like Figures 2 to 4 As shown, the lower cover 2 is provided with a liquid outlet 21, and a check valve 8 is provided at the liquid outlet 21. The check valve 8 has a slit 81. When the upper cover 1 is lifted, the slit 81 is in a closed state, which can prevent external air from entering the liquid outlet 21 and prevent the contents of the bottle from oxidizing or being contaminated. When the user squeezes the bottle, the liquid pressure inside the bottle opens the slit 81, and the contents of the bottle can flow out from the liquid outlet 21 through the slit 81.

[0030] In this embodiment, the cut 81 is cross-shaped. In practical applications, the cut 81 can also be in other shapes such as a straight line or a cross shape.

[0031] like Figure 2 and Figure 3 As shown, the inner wall of the anti-theft ring 6 is provided with several limiting blocks 61, which are used to engage with the bottle mouth groove on the bottle body.

[0032] like Figure 1 and Figure 4 As shown, the side wall of the lower cover 2 is provided with a ring-shaped anti-slip groove 22, which can increase the friction when the user twists the flip cover.

[0033] like Figure 2 and Figure 3 As shown, the inner wall of the lower cover 2 is integrally formed with internal threads 23 for flip-top assembly and disassembly.

[0034] The above are merely preferred embodiments of this utility model. Any technical solution that achieves the purpose of this utility model by essentially the same means shall fall within the protection scope of this utility model.
