[0034] The following refers to Figures 1 to 7 The pull ring cover and the packaging bottle provided according to the embodiments of the present application are described.

[0035] As shown in Figures 1 to 7 The pull ring cover according to the first aspect of the present application can be used for packaging bottles such as beer bottles, juice bottles, etc., and has a good sealing effect on the bottle opening of the packaging bottle. The pull ring cover of the present embodiment has the advantages of good opening smoothness and low opening difficulty, and well overcomes the problems of large opening force, time-consuming and laborious operation, and low opening smoothness of the pull ring cover in the prior art.

[0036] As shown in Figures 1 to 7 The structure of the pull ring cover includes a bottle cap body 100 and a pull ring 200.

[0037] The bottle cap body 100 has a groove 110 and a connecting arm. The opening of the groove 110 is downwardly open, and the groove 110 is a cylindrical groove. The thickness of the side wall of the groove 110 is uniform. The connecting arm includes a first extension 121, a circular arc portion 122 and a second extension 123, which are sequentially arranged from top to bottom. The length of the first extension 121 extends along the up-down direction of the bottle cap body 100, and the upper end of the first extension 121 is integrally formed with a side wall of the groove 110. The circular arc portion 122 extends in a direction away from the bottle cap body 100, and the upper end of the circular arc portion 122 is integrally formed with the lower end of the first extension 121, and the central angle of the circular arc portion 122 is α, α≥40°, and α≤60°. The upper end of the second extension 123 is integrally formed with the lower end of the circular arc portion 122, and the second extension 123 extends downwardly and obliquely away from the bottle cap body 100.

[0038] In the embodiment, the central angle of the circular arc portion 122 is 45°, and the extension direction of the second extension 123 forms an acute angle of 45° with the up-down direction. The connecting arm is located on the right side of the groove 110, the upper end of the first extension 121 is fixedly connected with the right side wall of the groove 110, the circular arc portion 122 bends towards the right side of the bottle cap body 100, the second extension 123 is arranged obliquely rightward from top to bottom, and the width direction of the connecting arm extends along the front-rear direction. As viewed along the up-down direction, the first extension 121 is in the shape of a segment of a circle. The bottle cap body 100 can be made of aluminum alloy material by stamping and drawing. The upper corners of the bottle cap body 100 are rounded.

[0039] The pull ring 200 is arranged below the bottle cap body 100 and is arranged opposite to the connecting arm. The pull ring 200 has a ring hole 210 for fingers to extend into, so that people can extend their fingers such as index fingers into the ring hole 210 to exert a pulling force on the pull ring 200. The upper end of the pull ring 200 is fixedly connected with the lower end of the second extension 123. Specifically, the pull ring 200 is a plastic part, and the pull ring 200 is integrally injection molded with the second extension 123.

[0040] The upper end of the pull ring 200 is provided with a protrusion 220, the protrusion 220 is integrally formed with the pull ring 200, and the protrusion 220 is located on the side of the pull ring 200 away from the bottle cap body 100. When the pull ring 200 is located on the right side of the bottle cap body 100, the protrusion 220 is located on the right side of the upper end of the pull ring 200; when the pull ring 200 is located on the left side of the bottle cap body 100, the protrusion 220 is located on the left side of the upper end of the pull ring 200. Moreover, the protrusion 220 is configured to abut against the outer peripheral wall of the bottle cap body 100 after the pull ring 200 swings upward, so that the abutting position of the protrusion 220 and the bottle cap body 100 forms a lever fulcrum for the pull ring 200 to open the bottle cap body 100.

[0041] In the present embodiment, as shown in Figure 1 and Figure 3 , the convex portion 220 is a pentahedron structure, wherein the convex portion 220 has one bottom surface and four side surfaces, the bottom surface of the convex portion 220 is integrally formed with the pull ring 200, the side surface of the convex portion 220 facing the bottle cap body 100 is an inner side surface, the side surface of the convex portion 220 facing away from the bottle cap body 100 is an outer side surface, the inner side surface is a concave curved surface, the outer side surface is a convex curved surface, and the remaining two side surfaces of the convex portion 220 are concave curved surfaces. A convex strip 221 is formed at the connection between the four side surfaces of the convex portion 220, the convex strip 221 extends along the width direction of the second extension portion 123, the convex strip 221 is in a circular arc shape, and the convex strip 221 is configured to abut against the outer peripheral wall of the bottle cap body 100, so that the abutment position of the convex strip 221 and the bottle cap body 100 forms a lever fulcrum, as shown in Figure 7 .

[0042] It can be understood that the convex portion 220 adopts the above structure design, so that the convex strip 221 is in a circular arc convex shape, which can avoid the situation that the abutting force applied by the convex portion 220 to the bottle cap body 100 is too concentrated, causing the bottle cap body 100 to be easily pierced, resulting in the convex portion 220 and the bottle cap body 100 being clamped together, and the bottle cap body 100 cannot be subsequently torn apart by pulling the pull ring 200.

[0043] The upper end of the pull ring 200 is connected to the lower end of the second extension portion 123 by a compression molding process, the pull ring 200 wraps around the second extension portion 123, so that the pull ring 200 is fixed to the second extension portion 123. Specifically, as shown in Figure 5 and Figure 6 , the pull ring 200 includes a first pull ring body 201 and a second pull ring body 202, the first pull ring body 201 is located on the side of the second pull ring body 202 close to the second extension portion 123, the first pull ring body 201 and the second pull ring body 202 are integrally formed and tightly wrap around the second extension portion 123.

[0044] In addition, a plurality of connecting through holes can be provided on the second extension portion 123, so that in the compression molding process, the molten plastic enters the connecting through holes, and after the plastic solidifies, a connecting column is formed, which can enhance the connection effect between the pull ring 200 and the second extension portion 123.

[0045] In addition, in order to facilitate the tearing of the bottle cap body 100 from the packaging bottle, a score line (or opening line) is usually formed on the bottle cap body 100. The score line can be arranged on the inner side or the outer side of the bottle cap body 100. Generally, the score line continuously extends from the peripheral wall of the bottle cap body 100 to the bottle cap top surface 140 of the bottle cap body 100, and the depth of the entire score line is uniform. Moreover, two score lines are arranged, and the two score lines are mirror-symmetrically arranged with respect to the center line of the bottle cap body 100. When a person pulls the pull ring 200, the bottle cap body 100 can be torn along the score line, thereby achieving the purpose of opening the pull ring cap. The shape of the score line is known to those skilled in the art, and will not be described here.

[0046] It can be understood that when a person first pulls open the pull ring cap on the packaging bottle, the person will exert a certain pulling force on the pull ring 200 to drive the pull ring 200 to swing upward by a certain amplitude, so that the convex portion 220 on the pull ring 200 can abut against the outer peripheral wall of the bottle cap body 100. In this process, the circular arc portion 122 can play a guiding role, so that the first extension portion 121 is more easily deformed, and the circular arc portion 122 can drive the first extension portion 121 to bend and deform upward, thereby enabling the pull ring cap to be smoothly opened along the circular arc portion 122, which is beneficial to improving the opening smoothness of the pull ring cap.

[0047] In the embodiment, the central angle of the circular arc portion 122 is 45°, so that, under the driving action of the circular arc portion 122, the bending degree of the first extension portion 121 is reduced, and only the bending angle of the first extension portion 121 needs to be less than or equal to 45°, so that the convex portion 220 can abut against the outer peripheral wall of the bottle cap body 100.

[0048] When the convex portion 220 abuts against the outer peripheral wall of the bottle cap body 100, the contact position between the convex portion 220 and the bottle cap body 100 becomes a lever fulcrum. At this time, according to the principle of the lever, a person can drive the pull ring 200 to swing upward with the lever fulcrum as the center by exerting a pressure on the end of the pull ring 200 away from the bottle cap body 100. In this process, under the driving action of the pull ring 200, the bottle cap body 100 will be torn along the score line, and then the part of the bottle cap body 100 between the two score lines will be lifted together with the connecting arm and the pull ring 200. At this time, since the part of the bottle cap body 100 outside the two score lines loses the connection, the bottle cap body 100 can be separated from the bottle mouth of the packaging bottle. Since there is a gap between the end of the score line and the bottle cap body 100, the bottle cap body 100 is still in an integrated state after being opened.

[0049] Compared with the existing way of lifting the pull ring 200 by fingers and pulling the pull ring 200, the pull ring cover provided in the embodiment adopts the above structural design, and through the guiding action of the arc part 122 and the lever action established between the convex part 220 and the bottle cap body 100, the opening smoothness of the pull ring cover can be improved, the opening difficulty of the pull ring cover can be reduced, and people can open the pull ring cover more easily and save more labor, so that the purpose of easy and convenient opening is achieved. Moreover, by adopting such a design, the first opening force of the pull ring cover can be reduced, the size of the first opening force is controlled within 30N, the pull ring cover is more easily opened, the quality of the pull ring cover can be improved, the opening experience of the packaging bottle can be improved, and the competitiveness of the pull ring cover product can be improved.

[0050] In some embodiments, as shown in Figures 1 to 7 The bottle cap body 100 is provided with notches 130. Specifically, the side wall of the groove 110 is provided with notches 130, the notches 130 are triangular, and the notches 130 are located at the connection between the first extension part 121 and the side wall of the groove 110. Two notches 130 are symmetrically arranged on the opposite sides of the first extension part 121 along the width direction of the first extension part 121. The sharp corners of the notches 130 are located on the length extension line of the first extension part 121. The sharp corner of the uppermost part of the notch 130 is taken as an intersection point, and a blanking section is arranged between the intersection point and the notch on the outer peripheral wall of the bottle cap body 100. The upper and lower dimensions of the blanking section can be 0.4mm.

[0051] It can be understood that when the convex part 220 is abutted against the outer peripheral wall of the bottle cap body 100 and forms a lever fulcrum, by applying an external force to the pull ring 200 by fingers, the pull ring 200 is driven to swing upward around the lever fulcrum. At this time, under the action of the lever, the notch arranged close to the notch 130 will be broken first, so that the pull ring cover is more labor-saving and time-saving, the first opening force is reduced, and people can more easily open the pull ring cover. When the notch is broken, people can pull the pull ring 200 to drive the bottle cap body 100 to tear along the notch.

[0052] In some embodiments, as shown in Figure 2 and Figure 5 The structure of the pull ring cover further includes a sealing gasket 300. The sealing gasket 300 is arranged on the groove bottom surface of the groove 110. The sealing gasket 300 is coaxially arranged with the bottle cap body 100. It can be understood that the sealing gasket 300 can be made of a thermoplastic elastomer with self-adhesion. When the pull ring cover is installed at the bottle mouth of the packaging bottle, the sealing gasket 300 can tightly adhere to the top surface of the bottle mouth and apply excellent sealing action to the bottle mouth. The sealing gasket 300 can be fixed on the bottle cap body 100 by hot pressing or adhesive bonding. The sealing gasket 300 can be transparent.

[0053] In one embodiment, the sealing gasket 300 is provided with a cylindrical groove 320 and an annular groove 310, wherein the cylindrical groove 320 is located at the middle of the sealing gasket 300, the opening of the cylindrical groove 320 is downwardly open, the opening of the annular groove 310 is also downwardly open, the annular groove 310 is coaxially arranged with the cylindrical groove 320, and the cross-sectional shape of the annular groove 310 is a non-right trapezoid. The wall surface of the annular groove 310 is configured to be in sealing contact with the bottle mouth.

[0054] It can be understood that when the pull ring cap is assembled on the packaging bottle, the annular groove 310 corresponds to the bottle mouth of the packaging bottle, the periphery of the bottle mouth is located in the annular groove 310, and the wall surface of the annular groove 310 will be deformed under the pressure of the bottle mouth, so that the sealing gasket 300 is better attached to the bottle mouth, and a better airtight effect is provided. The arrangement of the cylindrical groove 320 can make the annular groove 310 more easily deformed, increase the contact area between the sealing gasket 300 and the bottle mouth, and thus improve the sealing effect.

[0055] In some embodiments, the bottom surface of the groove 110 is provided with a two-dimensional code at the middle position.

[0056] It can be understood that the two-dimensional code can contain relevant information of the pull ring cap, such as production date, size, manufacturer, or purchase reward information for consumers, and the two-dimensional code can be arranged on the bottom surface of the groove 110 by printing. In the case of being provided with the sealing gasket 300, the sealing gasket 300 is transparent, and after the two-dimensional code is printed on the bottle cap body 100, the sealing gasket 300 is fixed on the bottle cap body 100, at this time, the sealing gasket 300 covers the two-dimensional code. Since the sealing gasket 300 is transparent, and the middle position of the sealing gasket 300 is provided with the cylindrical groove 320, the thickness of the middle position of the sealing gasket 300 is reduced, so that people can more easily and clearly see the two-dimensional code on the bottle cap body 100 and perform code scanning processing.

[0057] In other embodiments, the upper surface of the bottle cap body 100 is provided with a two-dimensional code.

[0058] Of course, in other embodiments, the two-dimensional code is printed on the top surface 140 of the bottle cap body 100 and the bottom surface of the groove 110.

[0059] In addition, as Figures 1 to 5 , Figure 7As shown, the upper end of the pull ring 200 is provided with an abutting portion 230, the abutting portion 230 is integrally formed with the pull ring 200, the abutting portion 230 is provided with two, the two abutting portions 230 are respectively and symmetrically arranged on the opposite sides of the convex portion 220 along the width direction thereof. It can be understood that when the pull ring cover is installed on the packaging bottle, the abutting portion 230 can abut on the peripheral wall of the packaging bottle, so as to determine the position of the pull ring 200 on the packaging bottle. The lower end of the pull ring 200 bends and extends away from the bottle cap main body 100 from top to bottom.

[0060] In the pull ring cover provided in the first aspect of the present application, the bottle cap main body 100 and the pull ring 200 are connected through the connecting arm, in the structure of the connecting arm, the first extension 121, the arc portion 122 and the second extension 123 are sequentially arranged and integrally formed, the first extension 121 is integrally formed with the bottle cap main body 100, the central angle of the arc portion 122 satisfies the condition that it is greater than or equal to 40° and less than or equal to 60°, and the second extension 123 is fixedly connected with the pull ring 200, so that when the pull ring cover on the packaging bottle is just pulled open, the arc portion 122 can play a good guiding role, the first extension 121 can be easily bent upward, the pull ring cover can be smoothly opened along the arc portion 122, the opening smoothness of the pull ring cover is improved, and the trajectory of each pull ring cover when being pulled open can be basically consistent.

[0061] Moreover, when the pull ring 200 swings upward to the position under the action of external force, the convex portion 220 on the pull ring 200 will abut on the outer peripheral wall of the bottle cap main body 100, so that the abutting portion between the convex portion 220 and the bottle cap main body 100 can become a lever fulcrum, the pull ring 200 drives the bottle cap main body 100 to move by using the lever principle, so that the bottle cap main body 100 can tear along the notch itself, to complete the opening work of the pull ring cover. Through such design, the opening process of the pull ring cover can be more time-saving and labor-saving, the opening difficulty is reduced, and the use satisfaction of the pull ring cover is improved.

[0062] As shown, Figures 1 to 7 As shown, the packaging bottle according to the second aspect of the present application comprises a bottle body and the pull ring cover according to the first aspect of the present application. The bottle body has a bottle mouth, and the pull ring cover is sealingly arranged on the bottle mouth.

[0063] It can be understood that the packaging bottle can be a beer bottle or a fruit juice bottle. In the process of installing the pull ring cover on the bottle mouth of the packaging bottle, the bottle cap main body 100 is sleeved on the crown-shaped bottle mouth of the packaging bottle, then the bottle cap main body 100 is compacted to enable the sealing gasket 300 to block the bottle mouth, and finally the edge of the bottle cap main body 100 is bent downward to enable the bottle cap main body 100 to be tightly pressed on the outer periphery of the bottle mouth, so that the pull ring cover seals the bottle mouth of the packaging bottle. After the pull ring cover is opened, the sealing gasket 300 still adheres to the inner side of the bottle cap main body 100.

[0064] In the packaging bottle provided in the second aspect of the present application, the pull ring cover with the unique structure can reduce the opening difficulty of the pull ring cover, improve the opening smoothness of the pull ring cover, and make people open the pull ring cover more smoothly and labor-saving, thereby improving the opening experience of the packaging bottle.
