Description

Technical Field

[0001] This utility model relates to the field of bottle cap structure technology, specifically to an easy-to-open anti-theft bottle cap. Background Technology

[0002] In everyday life, common cosmetic bottles / tubes, medicine bottles, and beverage bottles often have tamper-evident tear strips at the opening of the cap. These strips are primarily designed to prevent counterfeiters from using old containers or packaging to create and sell counterfeit products. This design employs a partially destructive opening method; when a consumer opens the packaging, it damages part of the original opening mechanism, leaving traces that are difficult to repair, restore, or conceal. Consumers can check the integrity of the tamper-evident tear strip to determine if the product packaging has been opened, thus ensuring the product's authenticity and safety.

[0003] For example, patent document CN217295549U provides a flip-top bottle cap that can improve production efficiency. It features a tamper-evident tear strip at the cap's connection point, allowing for horizontal tearing. For user convenience, both ends of the tear strip have protrusions for gripping, allowing the user to tear it open from either end. However, this design still has room for improvement in the ease of tearing the strip. Summary of the Invention

[0004] In response to the problems in related technologies, this utility model proposes an easy-to-open anti-theft bottle cap that allows users to tear open the tear strip from multiple angles, and the operation is more convenient than that of existing technologies.

[0005] This utility model is implemented as follows:

[0006] An easy-to-open anti-theft bottle cap, the anti-theft bottle cap is a flip cap, including an upper cap and a lower cap, the upper cap and the lower cap are rotatably connected at the rear, so that the upper cap can be flipped open and closed relative to the lower cap at the front; the lower cap is assembled on the bottle body.

[0007] The outer edge of the upper side of the lower cover is recessed to form a recessed platform; the upper side of the recessed platform is provided with an anti-theft tear strip; the anti-theft tear strip includes a broken part, and the two ends of the broken part are two connecting parts; only the lower side of the connecting part is connected to the recessed platform; an arc-shaped groove is formed between the broken part and the recessed platform;

[0008] When the upper cover and the lower cover are closed, the anti-theft tear strip is located on the front side of the upper cover; the front side of the upper cover is also provided with a first protrusion and a second protrusion; the second protrusion is adapted to the arc groove; the first protrusion is located on the upper side of the fracture part and protrudes beyond the front side of the fracture part;

[0009] The front surface of the lower cover is provided with a concave first guide surface, which is located below the fracture portion.

[0010] When opening the bottle cap, users can first tear the entire anti-theft tear strip from the side connecting part, and then open the top cap; users can also place their fingers on the first guide surface, move their fingers upward to the first protrusion, and apply force from bottom to top to the first protrusion to open the top cap. When the top cap is opened, the second protrusion presses against the broken part upward, pulling the entire anti-theft tear strip until the connecting part breaks from the platform and the top cap is opened.

[0011] Compared to existing technologies, this solution allows for both tearing off the anti-theft tear strip from both sides and indirectly tearing it off while opening the top cover. Specifically, the former requires observing the position of the tear strip's connecting part before applying precise force from that point; while the latter, thanks to the first guiding surface, allows for "blind opening" without observation, making the operation more convenient.

[0012] As a further optimization of the above solution, the front side of the connecting part is provided with one or more protrusions or ridges; or the front side of the connecting part protrudes beyond the front side of the fractured part.

[0013] The raised dots / textures make it easy to locate the connecting part with your fingers, and also make it easy to tear the connecting part apart.

[0014] As a further optimization of the above solution, the connecting part and the sinking platform are connected by one or more points, or by a thin sheet connection.

[0015] As a further optimization of the above solution, the front side of the top cover has a recess; the first convex part and the second convex part are both located on the recess; the two ends of the recess are respectively formed into two second guide surfaces; the anti-theft tear strip is adapted to be disposed in the center of the recess, and the two second guide surfaces are respectively exposed on the outside of the two connecting parts.

[0016] Place your finger on the second guide surface and gradually apply force along the second guide surface toward the connecting part to tear off the anti-theft tear strip.

[0017] As a further optimization of the above solution, the length of the anti-theft tear strip is less than or equal to 1 / 3 of the outer periphery of the top cover.

[0018] As a further optimization of the above solution, an elastic connecting bridge is provided between the upper cover and the lower cover; the connecting bridge is located on the rear side of the upper cover and the lower cover; connecting ribs are provided on both the left and right sides of the connecting bridge; the two ends of the connecting ribs are respectively connected to the upper cover and the lower cover.

[0019] A rotatable connection between the upper and lower covers is achieved through a connecting bridge.

[0020] As a further optimization of the above solution, the upper end of the bottle body is provided with a first opening; the upper surface of the lower cover is provided with a second opening; the second opening is located in the middle area of ​​the sinking platform; when the lower cover and the bottle body are connected, the first opening and the second opening are connected.

[0021] As a further optimization of the above solution, the lower surface of the upper cover is provided with a raised third protrusion; when the upper cover and the lower cover are closed, the third protrusion fits tightly with the second opening.

[0022] The third protrusion improves the sealing of the second opening when closed, preventing leakage. Furthermore, the third protrusion is hollow in the middle, forming an overall annular boss shape.

[0023] As a further optimization of the above solution, the lower cover has a first annular boss that protrudes downwards; the lower cover protrudes downwards at the second opening to form a second annular boss; the first annular boss is located on the outer periphery of the second annular boss; it also includes a cross-shaped one-way valve and a retaining ring;

[0024] The cross-shaped one-way valve includes a concave deformable part; the deformable part is made of elastic soft rubber material; the center of the deformable part is a cross-shaped crack; the outer peripheral edge of the deformable part is folded down to form an annular folded part; the fixing ring has a middle opening, and an annular limiting groove with the groove facing upward is provided on the outer periphery of the opening.

[0025] The folding portion is adapted to the annular limiting groove; the outer peripheral side of the fixing ring is tightly connected to the inner peripheral side of the first annular boss.

[0026] When the bottle is squeezed, the deformed part bulges outward and the cross-shaped crack opens, allowing liquids, ointments, etc., inside the bottle to be squeezed out from the cross-shaped one-way valve; after the bottle is released, the cross-shaped one-way valve returns to its original shape under the action of elasticity; the sealing effect is good.

[0027] Some traditional flexible packaging tubes often require different outlet diameters depending on the viscosity of the contents. However, too many different outlet diameters lead to increased costs. By setting a detachable retaining ring and a cross-shaped check valve, it is easy to change different outlet diameters during production. In other words, only the opening size of the check valve needs to be changed.

[0028] As a further optimization of the above solution, the protrusion height of the first annular boss is greater than the protrusion height of the second annular boss;

[0029] When the lower cap and the bottle body are connected, the first annular protrusion is inserted into the first opening and tightly fitted with the first opening.

[0030] The beneficial effects are as follows:

[0031] This invention provides a convenient anti-theft bottle cap that allows for easy opening of the tamper-evident strip. The tamper-evident strip can be torn off from either side, or indirectly while opening the top cap. The latter, aided by a first guiding surface, allows for "blind opening" without visual inspection, making operation more convenient. Furthermore, a detachable cross-shaped check valve and retaining ring are provided, facilitating the replacement of the check valve's diameter during production. Attached Figure Description

[0049] like Figures 1 to 6 As shown, this embodiment provides a conveniently openable anti-theft bottle cap. The anti-theft bottle cap is a flip-top, including an upper cap 1 and a lower cap 2. The upper cap 1 and the lower cap 2 are rotatably connected at the rear, allowing the upper cap 1 to be opened and closed relative to the lower cap 2 at the front. In this embodiment, an elastic connecting bridge 3 is provided between the upper cap 1 and the lower cap 2. The connecting bridge 3 is located at the rear of the upper cap 1 and the lower cap 2. Connecting ribs 4 are provided on both the left and right sides of the connecting bridge 3. The two ends of the connecting ribs 4 are respectively connected to the upper cap 1 and the lower cap 2. The rotatable connection between the upper cap 1 and the lower cap 2 is achieved through the connecting bridge 3.

[0050] The outer edge of the upper side of the lower cover 2 is recessed to form a recessed platform 2-1; the upper side of the recessed platform 2-1 is provided with an anti-theft tear strip 5. In this embodiment, the length of the anti-theft tear strip 5 is 1 / 3 of the outer periphery of the upper cover 1.

[0051] The anti-theft tear strip 5 includes a fracture portion 5-1, with two connecting portions 5-2 at each end. In this embodiment, the front side of the connecting portion 5-2 is provided with raised texture 5-3. The raised texture 5-3 facilitates finger positioning of the connecting portion 5-2 and makes it easy to tear the connecting portion 5-2 apart.

[0052] Only the lower side of the connecting part 5-2 is connected to the recessed platform 2-1; in this embodiment, the connecting part 5-2 and the recessed platform 2-1 are connected by a dot-like / rib-like connection.

[0053] An arc-shaped groove 6 is formed between the fractured part 5-1 and the sinking platform 2-1.

[0054] In this embodiment, the front side of the upper cover 1 has a recess 1-1, and the two ends of the recess 1-1 are respectively formed into two second guide surfaces. The upper cover 1 has a first protrusion 1-3 and a second protrusion 1-4 disposed vertically at the recess 1-1.

[0055] When the upper cover 1 and the lower cover 2 are closed, the anti-theft tear strip 5 is located on the front side of the recess 1-1 of the upper cover 1; the second protrusion 1-4 is adapted to the arc groove 6; the first protrusion 1-3 is located on the upper side of the fracture 5-1 and protrudes beyond the front side of the fracture 5-1; the anti-theft tear strip 5 is adapted to be located in the center of the recess 1-1, and the two second guide surfaces are exposed on the outside of the two connecting parts 5-2 respectively.

[0056] The front surface of the lower cover 2 is provided with a recessed first guide surface, which is located below the fracture part 5-1.

[0057] When opening the bottle cap, the user can first tear off the entire anti-theft tear strip 5 from the side connecting part 5-2, and then open the top cover 1; that is, place your finger on the second guide surface, and gradually apply force along the second guide surface towards the connecting part 5-2 to tear off the anti-theft tear strip 5.

[0058] Users can also place their fingers on the first guide surface, move their fingers upward to the first protrusion 1-3, and apply force from bottom to top to the first protrusion 1-3 to open the top cover 1. When the top cover 1 is opened, the second protrusion 1-4 presses against the broken part 5-1 and pulls the entire anti-theft tear strip 5 until the connecting part 5-2 breaks from the recessed platform 2-1 and the top cover 1 is opened.

[0059] Compared to existing technologies, this solution allows for tearing off the anti-theft tear strip 5 from both sides, or indirectly tearing it off while opening the top cover 1. Specifically, the former method requires observing the position of the connecting part 5-2 of the anti-theft tear strip 5 before applying force precisely from the connecting part 5-2; while the latter, thanks to the first guide surface, allows for "blind opening" without observation, making the operation more convenient.

[0060] The lower cap 2 is assembled onto the bottle body 7.

[0061] In this embodiment, the upper end of the bottle body 7 is provided with a first opening 7-1; the upper surface of the lower cover 2 is provided with a second opening 2-3; the second opening 2-3 is located in the middle area of ​​the sink platform 2-1.

[0062] In this embodiment, the lower surface of the upper cover 1 is provided with a raised third protrusion 1-5; the third protrusion 1-5 is hollow in the middle and is generally in the shape of an annular boss. When the upper cover 1 and the lower cover 2 are closed, the third protrusion 1-5 fits tightly with the second opening 2-3. The third protrusion 1-5 can improve the sealing of the second opening 2-3 when closed, and prevent leakage.

[0063] In this embodiment, the lower cover 2 has a first annular boss 2-4 protruding downwards; the lower cover 2 protrudes downwards at the second opening 2-3 to form a second annular boss 2-5; the first annular boss 2-4 is located on the outer periphery of the second annular boss 2-5; in this embodiment, the protrusion height of the first annular boss 2-4 is greater than the protrusion height of the second annular boss 2-5.

[0064] It also includes a cross-shaped check valve 8 and a retaining ring 9;

[0065] The cross-shaped check valve 8 includes a recessed deformable part 8-1; the deformable part 8-1 is made of elastic soft rubber material; the center of the deformable part 8-1 is a cross-shaped crack 8-2; the outer periphery of the deformable part 8-1 is folded down to form an annular folded part 8-3; the fixing ring 9 has a middle opening, and an annular limiting groove 9-1 with the groove facing upward is provided on the outer periphery of the opening.

[0066] The folding part 8-3 is adapted to the annular limiting groove 9-1; the outer peripheral side of the fixing ring 9 is tightly connected to the inner peripheral side of the first annular boss 2-4.

[0067] When the lower cover 2 and the bottle body 7 are connected, the first annular protrusion 2-4 is inserted into the first opening 7-1 and tightly connected with the first opening 7-1, and the first opening 7-1 and the second opening 2-3 are connected.

[0068] Some traditional flexible packaging tubes often require different outlet diameters depending on the viscosity of the contents. However, too many different outlet diameters lead to increased costs. By setting a detachable retaining ring 9 and a cross-shaped check valve 8, it is convenient to change different outlet diameters during production. That is, only the opening size of the check valve needs to be changed.

[0069] When the bottle body 7 is squeezed, the deformable part 8-1 bulges outward and the cross-shaped crack 8-2 opens, allowing liquids, ointments, etc. inside the bottle body 7 to be squeezed out from the cross-shaped one-way valve 8; after the bottle body 7 is released, the cross-shaped one-way valve 8 returns to its original shape under the action of elasticity; the sealing effect is good.
