Description

Technical Field

[0001] This utility model relates to a monochrome molded sealing flip-top structure, and belongs to the technical field of bottle cap sealing structure. Background Technology

[0002] In the production and use of packaging, the bottle cap is an important component of the overall structure, playing a major role in sealing.

[0003] Existing bottle packaging typically uses a single cap tightly threaded to the liquid outlet of the bottle for sealing. While simple in structure, this method offers poor sealing and is prone to leakage if not tightened properly after use. Patent CN118973914A discloses a flip-top bottle cap that allows easier access to the bottle's contents compared to traditional screw caps. The cap can be made of plastic materials, including PET, HDPE, LDPE, or polypropylene. The cap includes an opening through its top surface and a flip-top with a shape matching the opening, which is connected to the cap body via a flexible hinge. Multiple ridges are provided around the perimeter of the flip-top and the opening; these ridges interlock when the flip-top is pressed down to form a mechanical seal. The area-to-perimeter ratio of the cap opening can be less than approximately 3 / 16 inch to provide a seal against internal pressure from carbonated beverages. The cap can be secured to the bottle using threads, interlocking clamps, or adhesives, and a tamper-evident seal can also be provided on the cap. However, in this solution, the sealing connection between the flip cap and the bottle mouth is only achieved by the cooperation of the ridge on the inner side of the flip cap and the ridge on the outer side of the bottle mouth. The cap body and the bottle mouth still adopt the traditional threaded connection structure. During the production and assembly process, the cap body needs to be rotated for sealing and then the flip cap is put on, which is a relatively complicated process and poses a risk of contamination. Although a sealing film is set, the simple film structure is easily torn and cannot effectively restrain the flip cap. The flip cap is easily blown open by impact, resulting in leakage. Therefore, a single-color molded sealing flip cap structure is proposed to solve the problems existing in the prior art. Utility Model Content

[0023] See Figures 1-5 As shown, the technical solution adopted in this specific embodiment is as follows: it includes a bottle cap 1, the bottle cap 1 includes a cap body 11 and a flip cover 12, the cap body 11 is provided with a flip cover mounting groove 111 in the middle, and the flip cover 12 is installed in the flip cover mounting groove 111. In this embodiment, the flip cover is set in the flip cover mounting groove, and the front opening of the flip cover mounting groove is inclined, which makes it easier to open the flip cover.

[0024] The bottom of the flip cap 12 is provided with an inner sealing edge 123, and the bottom of the cap body 11 is provided with an outer sealing edge 112 near the inner sealing edge 123. Traditional sealing caps and bottle caps mostly use a threaded connection structure, which is more troublesome to assemble and is prone to insecure assembly. Therefore, in this embodiment, the outer sealing edge is connected by interlocking with the outer sealing limit edge of the bottle mouth. During production and assembly, only pressing is required to complete the installation. The inner sealing edge inside the flip cap is connected to the bottle mouth from the inside. The double interlocking structure is not only more convenient to install, but also more secure and has a better sealing effect.

[0025] To restrain the flip cover and prevent it from being easily opened when not in use, a first tear line 3 is provided between the cover body 11 and the flip cover 12. The first tear line is located in most of the main body, so that a certain amount of force is required to open the flip cover when in use, and it will not be easily opened by bumping.

[0026] More specifically, a first sealing limiting edge 1231 is provided on the outer side of the inner sealing edge 123, and a sealing mating groove 1232 is provided on the inner side of the first sealing limiting edge 1231. The first sealing limiting edge 1231 is a raised arc-shaped structure, and the sealing mating groove 1232 is a recessed arc-shaped structure. In this embodiment, a wavy sealing structure is provided on the outer side of the inner sealing edge, which is sealed and connected to the inner sealing edge of the bottle mouth on the inner side of the bottle mouth. It is an interference fit, and the wavy structure has a larger contact surface and a better sealing effect.

[0027] More specifically, a second sealing limiting edge 1121 is provided on the inner side of the outer sealing edge 112. The horizontal height of the second sealing limiting edge 1121 is lower than the height of the first sealing limiting edge 1231. In this embodiment, the sealing limiting edge at the flip-top is higher, making it easier to open, while the sealing limiting edge of the cap is lower, connecting with the bottle mouth at a lower position. The high and low positions form a tension-type fixing structure, which makes the connection with the bottle mouth more secure and the sealing performance better.

[0028] More specifically, the second sealing limiting edge 1121 is an arc-shaped protrusion structure, and the protrusion curvature is greater than that of the first sealing limiting edge 1231. The large curvature of the second sealing limiting edge can improve the firmness of the connection with the bottle mouth.

[0029] More specifically, the flip cover 12 is provided with a lifting ear 121 at one end. There is a gap between the lifting ear 121 and the flip cover mounting groove 111. The lifting ear makes it easier to open the flip cover, and the gap between the lifting ear and the flip cover mounting groove makes it easier to lift the lifting ear.

[0030] More specifically, the flip cover 12 is provided with a hinge 122 at the end away from the opening ear 121 to connect with the cover body 11. The non-rigid connection method is not easy to damage the flip cover and can be used multiple times.

[0031] More specifically, the transition section between the lifting ear 121 and the flip cover 12 is provided with a second tear line 4 that connects to the cover body 11. In this embodiment, two tear lines are provided, one on the main body and the other on the edge of the lifting ear. The multiple tear lines can reduce the difficulty of tearing, but can also constrain the flip cover at key positions to prevent it from being easily opened.

[0032] More specifically, the cap 11, the flip cap 12, and the first tear line 3 are all single-color integral molding structures, and the second tear line 4 is also a single-color integral molding structure with the cap 11 and the flip cap 12. The integrated structure not only eliminates the need for assembly during the production process, saving labor costs, but also eliminates the need for cap-closing operations, reducing the risk of human contact with the inside of the cap and improving production hygiene and safety. Furthermore, it saves on mold development costs and improves economic efficiency.

[0033] The working principle of this utility model is as follows: During the liquid filling installation of the packaging bottle, the bottle cap 1 is directly pressed onto the bottle body 2, so that the inner sealing edge 123 of the flip cap 12 is pressed into the inner side of the bottle mouth. At the same time, the outer sealing edge 112 of the cap body 11 is tightly against the outer side of the bottle mouth. The 1232 on the inner sealing edge 123 cooperates with the inner sealing edge 21 of the bottle mouth on the inner wall of the bottle mouth. The first sealing limiting edge 1231 locks the inner sealing edge 21 of the bottle mouth, and the second sealing limiting edge 1121 on the outer sealing edge 112 locks the outer sealing edge 22 of the bottle mouth on the outer side of the bottle mouth. The cap body 11 is connected and fixed to the bottle body 2 through the outer sealing edge 112, and this is achieved only by pressing and fastening. The cap 12 is fixed in place. After the cap 12 is connected to the bottle mouth, the horizontal height of the second sealing limit edge 1121 is lower than the height of the first sealing limit edge 1231. The inner and outer sides are connected in a high-low stretching manner to complete the sealing connection with the bottle mouth. This not only makes the connection tighter but also improves the sealing effect. In order to facilitate the opening of the cap 12 and also to restrain the cap 12 and prevent it from being easily opened, interval tear lines are set, namely the first tear line 3 of the main body and the second tear line 4 at the tear opening. Since it is an integrated structure and the same material as the bottle cap, it is a thin film structure, which can restrain the cap to a certain extent and prevent it from being easily knocked open.

[0034] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
