Description

Technical Field

[0001] The present application relates to the field of packaging technology, and in particular to an environmentally friendly detachable bottle cap and a packaging bottle. Background Art

[0002] In the field of packaging technology, the core function of a bottle cap is to seal the bottle body, but in order to better meet different usage scenarios, different bottle caps will be designed with more functions. Bottle caps with anti-theft functions are difficult to separate from the bottle body after assembly, and tools are usually required to remove the bottle cap from the bottle body, so the bottle body and bottle cap are usually discarded together. However, the bottle cap and the bottle body are often made of different materials. Failure to sort the garbage is not conducive to environmental protection and recycling of different materials. Therefore, it is difficult to balance anti-theft performance and removable performance.

[0003] In order to solve the problem that the bottle body and the bottle cap are difficult to separate, the related art adopts the method of directly pulling open the buckle of the lower cover through the strap connecting the lower cover and the upper cover of the bottle cap to remove the bottle cap from the bottle body. However, the strap of the bottle cap in the related art is easy to break during the removal process, resulting in the inability to complete the removal. In order to reduce the possibility of strap breakage, the method of increasing the weight of the bottle cap is often adopted, but this will lead to an increase in the amount of plastic used.

[0047] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] In the following description, the up and down directions refer to Figure 1 and Figure 2 In addition, the embodiment of the present application only focuses on the disassembly-related structure of the environmentally friendly detachable bottle cap, and other parts of the environmentally friendly detachable bottle cap can be set as any bottle cap structure suitable for combining with the disassembly-related structure of the embodiment of the present application.

[0049] like Figures 1 to 5D As shown, the first aspect of the present application provides an environmentally friendly detachable bottle cap, which includes a cap body B, a buckle ring 11 and an outer ring 12.

[0050] The buckle 11 is connected to the cap body B, and includes a stopper 111 for connecting the environmentally friendly detachable bottle cap to the bottle body. The buckle 11 has a first weak portion 11A, which extends from one axial end of the buckle 11 along the environmentally friendly detachable bottle cap to the other axial end of the buckle 11 along the environmentally friendly detachable bottle cap, so that after the first weak portion 11A is destroyed, the buckle 11 is separated from both sides of the circumference of the environmentally friendly detachable bottle cap located at the first weak portion 11A.

[0051] The outer ring 12 is connected to the cap body B and is arranged on the outer periphery of the buckle 11. The outer ring 12 has a second weak portion 12A, which extends from one axial end of the outer ring 12 along the environmentally friendly detachable bottle cap to the other axial end of the outer ring 12 along the environmentally friendly detachable bottle cap, so that after the second weak portion 12A is destroyed, the outer ring 12 is separated from both sides of the circumference of the environmentally friendly detachable bottle cap located at the second weak portion 12A.

[0052] The environmentally friendly detachable bottle cap of the embodiment of the present application includes a buckle 11 and an outer ring 12 arranged outside the buckle 11. After using the packaging bottle having a bottle body (not shown) and the environmentally friendly detachable bottle cap connected to the bottle body, the outer ring 12 and the buckle 11 are arranged in layers, and the two can be arranged to be relatively thin compared to other parts. At least a part of the outer ring 12 can be removed by destroying the second weak part 12A of the outer ring 12, and then at least a part of the buckle 11 can be removed by destroying the first weak part 11A of the buckle 11, so that the stopper 111 is released from the bottle mouth or is easy to be released, so that the bottle body and the environmentally friendly detachable bottle cap are easily separated, and the anti-theft performance and detachable performance of the bottle cap are better balanced. After use, the bottle body and the environmentally friendly detachable bottle cap are separated, which is conducive to achieving garbage classification and recycling, and is also conducive to the secondary use of the bottle, which helps environmental protection and improves efficiency.

[0053] exist Figures 1 to 5D In the illustrated embodiment, the cap body B includes the remaining parts of the environmentally friendly detachable bottle cap except the buckle 11 and the outer ring 12 .

[0054] The stopper 111 may be provided as one or more stopper portions along the axial direction, for example Figures 1 to 5D In the embodiment shown, a double-layer stopper is provided. Each layer of the stopper may include a plurality of stopper projections distributed along the circumferential direction.

[0055] like Figures 1 to 5D As shown, in some embodiments of the environmentally friendly detachable bottle cap, the first weak portion 11A extends along the axial direction of the environmentally friendly detachable bottle cap; and / or the second weak portion 12A extends along the axial direction of the environmentally friendly detachable bottle cap.

[0056] The first weak portion 11A and / or the second weak portion 12A extend along the axial direction of the environmentally friendly detachable bottle cap, which is beneficial to making the buckle 11 where the first weak portion 11A is located and / or the outer ring 12 where the second weak portion 12A is located relatively less in strength on the basis of making the first weak portion 11A easy to destroy and the corresponding part of the buckle 11 separated after destruction and / or the second weak portion 12A easy to destroy and the corresponding part of the outer ring 12 separated after destruction, and also facilitating the processing and manufacturing along the first weak portion 11A and / or the second weak portion 12A.

[0057] The first weak portion 11A may be, for example, a groove on the buckle 11 ; the second weak portion 12A may be, for example, a groove on the outer ring 12 .

[0058] like Figures 1 to 5D As shown, in some embodiments of the environmentally friendly removable bottle cap, the buckle 11 is connected to the cap body B of the environmentally friendly removable bottle cap through a third weak portion 14; the outer ring 12 is connected to the cap body B of the environmentally friendly removable bottle cap and / or the buckle 11 through a fourth weak portion 13.

[0059] The buckle ring 11 is connected to the environmentally friendly detachable bottle cap except that the buckle ring 11 and the cap body B are connected through the third weak portion 14, so that when the environmentally friendly detachable bottle cap is removed from the bottle body, the buckle ring 11 and the cap body B of the environmentally friendly detachable bottle cap are easier to separate. The outer ring 12 and the rest of the environmentally friendly detachable bottle cap (including the cap body B and the buckle ring 11) other than the outer ring 12 are connected through the fourth weak portion 13, so that when the environmentally friendly detachable bottle cap is removed from the bottle body, the outer ring 12 and the rest of the environmentally friendly detachable bottle cap (including the cap body B and the buckle ring 11) other than the outer ring 12 are easier to separate.

[0060] like Figures 1 to 5D As shown, in some embodiments of the environmentally friendly removable bottle cap, the third weak portion 14 extends along the circumference of the environmentally friendly removable bottle cap; and / or the fourth weak portion 13 extends along the circumference of the environmentally friendly removable bottle cap. Figures 1 to 5D As shown, in some embodiments of the environmentally friendly removable bottle cap, the third weak portion 14 extends along the entire circumference of the environmentally friendly removable bottle cap; and / or the fourth weak portion 13 extends along the entire circumference of the environmentally friendly removable bottle cap; and / or the third weak portion 14 and the fourth weak portion 13 are respectively arranged at the axial ends of the environmentally friendly removable bottle cap; and / or the fourth weak portion 13 connects the outer ring 12 and the buckle 11.

[0061] The above arrangement is conducive to relatively uniform force on the circumferentially distributed stopper of the environmentally friendly detachable bottle cap after being assembled with the bottle body, thereby facilitating the environmentally friendly detachable bottle cap to be firmly installed on the bottle body before removal. Among them, the fourth weak portion 13 connects the outer ring 12 and the buckle ring 11, which is conducive to the strength of the buckle ring 11 not being weakened, thereby also facilitating the environmentally friendly detachable bottle cap to be firmly installed on the bottle body before removal.

[0062] The third weak portion 14 is, for example, a first connecting strip extending along the circumferential direction of the environmentally friendly detachable bottle cap between the top of the buckle 11 and the cap body B of the environmentally friendly detachable bottle cap, and the first connecting strip can be set to be thinner than the buckle 11, so that when the environmentally friendly detachable bottle cap is removed from the bottle body, the third weak portion 14 is easily destroyed, thereby facilitating the separation of the buckle 11 from the cap body B. The fourth weak portion 13 is, for example, a second connecting strip extending along the circumferential direction of the environmentally friendly detachable bottle cap connecting the buckle 11 and the bottom of the outer ring 12, wherein the second connecting strip can be set to be thinner than the buckle 11 and the outer ring 12, so that when the environmentally friendly detachable bottle cap is removed from the bottle body, the fourth weak portion 13 is easily destroyed, thereby facilitating the separation of the outer ring 12 from the buckle 11.

[0063] like Figures 1 to 5DAs shown, in some embodiments of the environmentally friendly detachable bottle cap, a connecting portion 15 is provided between the outer ring 12 and the buckle 11, so that after the second weak portion 12A of the outer ring 12 is destroyed and the outer ring 12 is at least partially separated from the remaining portion of the environmentally friendly detachable bottle cap other than the outer ring 12 (including the cap body B and the buckle 11), the force applied to the outer ring 12 can be transmitted to the first weak portion 11A of the buckle 11 through the connecting portion 15 to destroy the first weak portion 11A.

[0064] In this embodiment, the connecting part is a third connecting strip extending along the circumference of the environmentally friendly detachable bottle cap and arranged at the bottom of the buckle 11 and the outer ring 12. The third connecting strip is connected to the second connecting strip along the circumference, and the third connecting strip is thicker than the second connecting strip, so that after the second connecting strip is destroyed, the third connecting strip is not easily destroyed relative to the second connecting strip, but the force applied to the outer ring 12 can be transmitted to the first weak portion 11A of the buckle 11 through the third connecting strip to destroy the first weak portion 11A, and further separate the buckle 11 from the cap body B.

[0065] like Figure 6 As shown, in some embodiments, the environmentally friendly detachable bottle cap further includes a reinforcing structure connecting the connecting portion 15, the outer ring 12 and the buckle 11. The reinforcing structure allows the outer ring 12, the buckle 11 and the connecting portion 15 to be connected together and peeled off together, further reducing the difficulty of damaging the first weak portion 11A and making it easier to start peeling the buckle 11.

[0066] like Figure 6 In the illustrated embodiment, the reinforcement structure is a reinforcement rib that simultaneously connects the outer ring 12 , the buckle 11 and the connecting portion 15 . Figure 6 In order to clearly show the connection portion 15 and the reinforcing ribs, the outer ring is not shown.

[0067] like Figures 1 to 5D As shown, in some embodiments of the environmentally friendly removable bottle cap, the first weak portion 11A and the second weak portion 12A are staggered along the circumference of the environmentally friendly removable bottle cap; and / or the buckle 11 and the outer ring 12 are at least partially spaced apart along the radial direction of the environmentally friendly removable bottle cap.

[0068] The first weak portion 11A and the second weak portion 12A are staggered along the circumference of the environmentally friendly detachable bottle cap, which is beneficial to preventing the second weak portion 12A from being accidentally damaged due to external force when the environmentally friendly detachable bottle cap is installed on the bottle body, which would expose the first weak portion 11A and make it easy to be damaged, thereby preventing the environmentally friendly detachable bottle cap from being accidentally separated from the bottle body.

[0069] The buckle ring 11 and the outer ring 12 are at least partially spaced apart along the radial direction of the environmentally friendly detachable bottle cap, so that when the outer ring 12 is subjected to an unexpected impact, the gap G between the buckle ring 11 and the outer ring 12 forms a buffer, reducing the impact on the buckle ring 11, thereby helping to reduce the accidental destruction or damage of the first weak portion 11A and the buckle ring 11, thereby helping to prevent the environmentally friendly detachable bottle cap from accidentally separating from the bottle body. In addition, it is also beneficial to the processing and forming of the environmentally friendly detachable bottle cap, for example, it is beneficial to the forming of at least one of the first weak portion 11A, the second weak portion 12A, the second connecting strip and the third connecting strip.

[0070] like Figures 1 to 5D As shown, in some embodiments of the environmentally friendly detachable bottle cap, the environmentally friendly detachable bottle cap includes an upper cover 2, a lower cover 1 and a shoulder strap 3. In this embodiment, the cap body B includes the upper cover 2, the rest of the lower cover 1 except the buckle 11 and the outer ring 12, and the shoulder strap 3.

[0071] The lower cover 1 includes a buckle 11 and an outer ring 12. The upper cover 2 is rotatably connected to the lower cover 1 through a shoulder strap 3, and the second weak portion 12A is arranged adjacent to the shoulder strap 3 along the circumference of the environmentally friendly detachable bottle cap, so that the force applied to the upper cover 2 can be transmitted to the second weak portion 12A of the outer ring 12 through the shoulder strap 3 to destroy the second weak portion 12A.

[0072] The above arrangement is conducive to directly starting to remove the environmentally friendly detachable bottle cap by applying force to the upper cover 2, without setting an initial force-applying part. Not only does the improved structure of the embodiment of the present application make it suitable for bottle caps with shoulder straps, but it is also conducive to simplifying the disassembly structure of the environmentally friendly detachable bottle cap. Since the outer ring 12 and the buckle 11 can be set to be relatively thin, it is conducive to preventing the environmentally friendly detachable bottle cap from breaking when removing it with a shoulder strap, thereby improving the removal success rate of the environmentally friendly detachable bottle cap.

[0073] like Figures 1 to 5D As shown, in some embodiments of the environmentally friendly detachable bottle cap, the first weak portion 11A and the second weak portion 12A are located on the same side of the strap 3 along the circumference of the environmentally friendly detachable bottle cap, and the first weak portion 11A is circumferentially away from the strap 3 relative to the second weak portion 12A.

[0074] This arrangement facilitates first tearing the second weak portion 12A through the shoulder strap 3, so that when the environmentally friendly detachable bottle cap is separated from the bottle body, the outer ring is removed first.

[0075] The second aspect of the present application provides a packaging bottle, comprising a bottle body and the environmentally friendly detachable bottle cap of the first aspect of the present application, the environmentally friendly detachable bottle cap is connected to the bottle body via a buckle 11. The packaging bottle of the embodiment of the present application has the advantages of the environmentally friendly detachable bottle cap of the embodiment of the present application.

[0076] In the above embodiment, the outer ring 12 and the buckle ring 11 are designed in layers, which is conducive to realizing a detachable design based on the original weight of the bottle cap. The disassembly is divided into two steps:

[0077] The second weak portion 12A of the outer ring 12 is torn open by the strap 3. Figure 5A The outer ring 12 is connected to the buckle 11 through a thin second connecting strip, so the tearing force required during the removal of the outer ring 12 is small, and the shoulder strap 3 is not easy to break. Figure 5B shown.

[0078] After the second connecting strip is completely torn off, the buckle 11 is basically exposed to the outside. Figure 5C As shown. Since the outer ring 12 is connected to the buckle ring 11 through the third connecting strip, the torn outer ring is used as a handle, the first weak portion 11A of the buckle ring 11 is torn, and then the first connecting strip between the buckle ring 11 and the cap body B of the environmentally friendly detachable bottle cap is torn, and the bottle body and the environmentally friendly detachable bottle cap can be easily separated through the handle, as shown. Figure 5D shown.

[0079] Therefore, the environmentally friendly detachable bottle cap of the embodiment of the present application is conducive to achieving the purpose of easy disassembly without increasing or excessively increasing the gram weight. After using the product, consumers separate the bottle and the cap before discarding the packaging to achieve garbage classification and recycling, which is conducive to balancing the anti-theft performance and detachable performance of the bottle cap, and is beneficial to environmental protection while achieving industrial mass production and maintaining reliability.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solution requested for protection in this application.
