[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0045] The following is combined with Figures 1-15 The anti-theft bottle cap and beverage bottle provided by the utility model embodiments are described in detail through specific implementation examples and application scenarios.
[0046] In the first aspect, such as Figure 1 , Figure 2 , Figure 6 , Figure 9 , Figure 10 and Figure 14 As shown, this embodiment of the utility model provides an anti-theft bottle cap 1, including: a cap body 11 and an anti-theft structure 12;
[0047] The cap 11 includes a main cap 111 and a locking member 112. The main cap 111 has an opening 1110, and the locking member 112 is located in the opening 1110 and is configured to be adapted to the locking structure on the bottle body 2. The anti-theft structure 12 is located between the main cap 111 and the locking member 112.
[0048] When the anti-theft structure 12 is intact, the locking member 112 is connected to the locking structure; when the anti-theft structure 12 is damaged, the locking member 112 can be separated from the locking structure.
[0049] It is understandable that, based on the material used for the anti-theft bottle cap 1, the anti-theft bottle cap 1 is a plastic cap. Depending on its function, the anti-theft bottle cap 1 can be a sealing cap for encapsulating the bottle opening, or it can be a decorative cap fitted over the existing cap on the bottle body 2; there are no specific limitations on this.
[0050] For the cap body 11 of the anti-theft bottle cap 1, the shape of the locking member 112 is adapted to the shape of the opening 1110 on the main cap 111, so that the locking member 112 can block the opening 1110 when the anti-theft structure 12 is not damaged. The main cap 111 is roughly cap-shaped, and the main cap 111 is the main body of the cap body 11. The locking member 112 can be detachably set at the opening 1110 or movable at the opening 1110, without specific limitation.
[0051] Meanwhile, the anti-theft structure 12 serves as a temporary connection between the main cover 111 and the locking member 112. The anti-theft structure 12 can be an adhesive structure, sticker, solder joint, etc. Consumers can visually inspect whether the anti-theft structure 12 is missing or broken to determine if it has been damaged. Specifically, when the anti-theft structure 12 is intact, the main cover 111 and the locking member 112 are connected at the anti-theft structure 12; when the anti-theft structure 12 is damaged, the main cover 111 and the locking member 112 separate at the anti-theft structure 12.
[0052] The anti-theft bottle cap 1 provided by this utility model configures the cap body 11 of the anti-theft bottle cap 1 as a main cap 111 and a locking member 112. The anti-theft structure 12 is set between the main cap 111 and the locking member 112. The anti-theft structure 12 can form an anti-theft protection. When the anti-theft structure 12 is not damaged, the anti-theft bottle cap 1 can be prevented from detaching from the bottle body 2 based on the connection between the locking member 112 and the locking structure on the bottle body 2, thereby forming another anti-theft protection. Only when the anti-theft structure 12 is damaged can the locking member 112 be separated from the locking structure, so that the anti-theft bottle cap 1 can be separated from the bottle body 2. At this time, the consumer can drink the beverage in the bottle body 2.
[0053] Therefore, compared with the anti-theft design of existing beverage bottle caps, the anti-theft bottle cap 1 shown in this utility model can form a second level of anti-theft protection, which can effectively prevent beverage bottles from being opened non-destructively before sale, thereby achieving a better anti-theft effect.
[0054] In the application scenario of this embodiment, non-destructive opening refers to the opening method of separating the anti-theft bottle cap 1 from the bottle body 2 without damaging the anti-theft structure 12 and the connection structure formed by the locking member 112 and the locking structure.
[0055] In some embodiments, such as Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the locking member 112 has a first tooth 11201 and a locking structure that is capable of engaging with the first tooth 11201.
[0056] Specifically, the first tooth 11201 is disposed on the side of the locking member 112 facing the bottle mouth 21 of the bottle body 2, and the second tooth 201 is disposed on the outer side wall of the bottle mouth 21; when no opening operation is performed on the anti-theft bottle cap 1, that is, when the anti-theft structure 12 is not damaged, the first tooth 11201 and the second tooth 201 engage so that the cap 11 cannot rotate relative to the bottle mouth 21 of the bottle body 2.
[0057] In practical applications, the first tooth 11201 extends into an arc-shaped tooth relative to the central axis of the bottle mouth 21, and the second tooth 201 extends into a toothed ring relative to the central axis of the bottle mouth 21. This design ensures that the first tooth 11201 and the second tooth 201 mesh when the cap 11 of the anti-theft bottle cap 1 is fitted onto the bottle mouth 21 of the bottle body 2 in any posture, thus improving the convenience of closing the anti-theft bottle cap 1.
[0058] In some embodiments, such as Figure 10 , Figure 12 , Figure 14 and Figure 15As shown, the locking member 112 has a first latching portion 11211 and a locking structure that is a second latching portion 211 that can latch into the first latching portion 11211.
[0059] Understandably, the first latching part 11211 is located on the side of the locking member 112 facing the bottle opening 21 of the bottle body 2, and the second latching part 211 is located on the outer wall of the bottle opening 21 or on the outer wall of the bottle body 2 near the bottle opening 21. When no opening operation is performed on the anti-theft bottle cap 1, that is, when the anti-theft structure 12 is not damaged, the first latching part 11211 and the second latching part 211 are engaged, so that the cap 11 cannot rotate relative to the bottle opening 21 of the bottle body 2, nor can the cap 11 be detached from the bottle opening 21 of the bottle body 2 along the axial direction.
[0060] In practical applications, one of the first latching portion 11211 and the second latching portion 211 is a latching tongue, and the other is a latching groove. In this embodiment... Figure 14 and Figure 15 The diagram illustrates the configuration of the first latching part 11211 as a latching tongue and the second latching part 211 as a latching slot.
[0061] When the first latching part 11211 is a latching tongue and the second latching part 211 is a latching groove, the cap 11 of the anti-theft bottle cap 1 needs to be fitted onto the bottle mouth 21 of the bottle body 2 in a set posture in order to achieve the latching tongue being latched into the latching groove.
[0062] In some embodiments, such as Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, the locking member 112 is rotatably disposed in the opening 1110; when the anti-theft structure 12 is damaged, the locking member 112 is configured to rotate relative to the main cover 111 to separate from the locking structure.
[0063] It is understandable that the locking member 112 is provided with a hinge shaft on its side, and the side wall of the opening 1110 is provided with a hinge hole. The hinge shaft is rotatably inserted into the hinge hole so that the locking member 112 can be rotatably positioned at the opening 1110.
[0064] To ensure that the locking member 112 can rotate stably at the opening 1110 of the main body cover 111, two hinge shafts are provided, which are located on opposite sides of the locking member 112. Two hinge holes are provided, which are located on opposite sidewalls of the opening 1110 and are arranged opposite to the two hinge shafts.
[0065] When the anti-theft mechanism 12 is intact, it ensures that the locking member 112 is engaged in the opening 1110, and the locking member 112 will not rotate relative to the main cover 111 at the opening 1110. When the anti-theft mechanism 12 is damaged, the connection between the main cover 111 and the locking member 112 is released, and the operator can then drive the locking member 112 to rotate relative to the main cover 111 towards the side away from the bottle body 2, thereby separating it from the locking mechanism.
[0066] In practical applications, considering that the locking element 112 may separate from the locking structure under external force, the structural form of the locking element 112 can be set according to actual needs to ensure that the locking element 112 undergoes significant structural deformation after separating from the locking structure. At this time, the locking element 112 cannot be rotated again to reconnect the locking element 112 with the locking structure, thereby further achieving the purpose of anti-theft protection.
[0067] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, opening 1110 is a through hole, a portion of which extends to the top of the main cover 111 and another portion extends to the side wall of the main cover 111; the first end of locking member 112 is rotatably connected to the top of the main cover 111, and the second end of locking member 112 extends toward the side wall of the main cover 111 and is configured to be connected to the locking structure.
[0068] It is understood that the through hole includes a first hollow area and a second hollow area, which are connected. The first hollow area is located on the top of the main body cover 111, and the second hollow area is located on the side wall of the main body cover 111.
[0069] Since the first end of the locking member 112 is rotatably connected to the top of the main body cover 111, the locking member 112 and the top of the main body cover 111 can be rotatably connected along an axis parallel to the top of the main body cover 111. The first tooth 11201 can be provided at the second end of the locking member 112 and located on the side of the locking member 112 facing the bottle mouth 21 of the bottle body 2.
[0070] Based on the shape of the through hole, this embodiment can ensure that the locking member 112 can be flipped at a large angle relative to the main cover 111. Thus, when the anti-theft structure 12 is damaged, it is easy to control the locking member 112 to flip towards the side away from the bottle body 2, so as to separate the first tooth 11201 on the locking member 112 from the second tooth 201 on the bottle body 2.
[0071] In some embodiments, such as Figure 1 , Figure 3 and Figure 4As shown, the locking member 112 includes a top plate 1121 and a side plate 1122 that are bent and connected; the end of the top plate 1121 away from the side plate 1122 is rotatably connected to the top of the main cover 111, and the end of the side plate 1122 away from the top plate 1121 is configured to be connected to the locking structure.
[0072] When the anti-theft structure 12 is not damaged, the top plate 1121 is embedded in the area of the through hole corresponding to the top of the main cover 111, and the side plate 1122 is embedded in the area of the through hole corresponding to the side wall of the main cover 111.
[0073] The side plate 1122 is provided with the first tooth 11201 at one end away from the top plate 1121. The first tooth 11201 is located on the side of the side plate 1122 facing the bottle mouth 21 of the bottle body 2.
[0074] In some embodiments, such as Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 14 As shown, the opening 1110 is a notch formed on the edge of the main cover 111. The notch has an open end and a bottom end opposite to the open end. The first end of the locking member 112 is rotatably disposed at the bottom end of the notch, and the second end of the locking member 112 extends toward the open end of the notch and is configured to connect with the locking structure.
[0075] Specifically, the locking member 112 shown in this embodiment can rotate relative to the notch on the main body cover 111, and the shape of the locking member 112 is adapted to the shape of the notch on the main body cover 111.
[0076] The second end of the locking member 112 is provided with a first latching part 11211, which is located on the side of the locking member 112 facing the bottle body 2. The outer wall of the bottle body 2 near the bottle mouth 21 is provided with a second latching part 211. When the anti-theft structure 12 is not damaged, the locking member 112 is embedded in the notch, and the first latching part 11211 and the second latching part 211 are latched together. When the anti-theft structure 12 is damaged, the operator can drive the locking member 112 to rotate relative to the main cover 111 on the side away from the bottle body 2, so as to separate the first latching part 11211 and the second latching part 211.
[0077] In some embodiments, such as Figure 4 and Figure 12 As shown, the locking member 112 is provided with a force-applying part 1120, which is used to receive external force to drive the locking member 112 to rotate relative to the main body cover 111.
[0078] For example, the force-applying part 1120 can be a protrusion provided on the locking member 112, and the protrusion can be a sheet-like protrusion or a strip-like protrusion.
[0079] For example, the first end of the locking member 112 is rotatably disposed at the opening 1110 of the main body cover 111, and the force-applying part 1120 is disposed at the second end of the locking member 112. This design can ensure that the torque is maximized when the force-applying part 1120 applies force, making it easier for the operator to control the rotation of the locking member 112 relative to the main body cover 111, thereby achieving separation from the locking structure.
[0080] In some embodiments, such as Figure 1 and Figure 9 As shown, the anti-theft structure 12 includes a spot-welded structure, which is connected to the joint between the main body cover 111 and the locking member 112.
[0081] Understandably, both the main cap 111 and the locking element 112 of the anti-theft bottle cap 1 are plastic parts. When the locking element 112 is embedded in the opening 1110 of the main cap 111, the seam between the main cap 111 and the locking element 112 can be spot-welded to form a spot-welded structure. Thus, when opening the anti-theft bottle cap 1, the operator can use sufficient force to break the spot-welded structure, thereby separating the main cap 111 and the locking element 112.
[0082] In practical applications, depending on the number of spot welds, multiple spot weld structures can be formed at the joint between the main cover 111 and the locking member 112, and these multiple spot weld structures are arranged at intervals along the extension direction of the joint. Specifically, the spot weld structures are located at the joints corresponding to the side walls of the cover 11.
[0083] In some embodiments, the anti-theft structure 12 includes a sticker that is adhered to the seam between the main cap 111 and the locking member 112. When opening the anti-theft bottle cap 1, the operator can separate the main cap 111 and the locking member 112 by peeling off the sticker at the seam between the main cap 111 and the locking member 112.
[0084] Regarding the structural design of the anti-theft structure 12, since the spot welded structure cannot be opened non-destructively, the spot welded structure has better anti-theft performance than the sticker, and the spot welded structure does not have the problem of being contaminated during transportation.
[0085] In the second aspect, such as Figure 5 , Figure 6 , Figure 13 and Figure 14 As shown, this utility model also provides a beverage bottle, including: a bottle body 2 and an anti-theft bottle cap 1 as described above;
[0086] The bottle body 2 has a bottle mouth 21, and the outer wall of the bottle mouth 21 is provided with a locking structure. The anti-theft bottle cap 1 is placed on the bottle mouth 21, and the locking element 112 on the anti-theft bottle cap 1 is configured to be connected to the locking structure.
[0087] Since the beverage bottle includes an anti-theft cap 1, and the specific structure of the anti-theft cap 1 is as described in the above embodiments, the beverage bottle of this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiments, which will not be described in detail here.
[0088] In some embodiments, such as Figure 7 and Figure 15 As shown, the beverage bottle also includes: an inner cap 3; the inner cap 3 is placed on the bottle mouth 21, and the cap body 11 is placed on the outside of the inner cap 3.
[0089] It is understandable that the inner wall of the inner cover 3 is provided with internal threads, and the peripheral wall of the bottle mouth 21 is provided with external threads. Based on the threaded connection between the internal and external threads, the inner cover 3 can be detachably installed at the bottle mouth 21.
[0090] Meanwhile, the cap 11 is placed on the outside of the inner cap 3 and is interference-fitted with the inner cap 3. At this time, the anti-theft bottle cap 1 functions as a decorative cap. In practical applications, the cap 11 of the anti-theft bottle cap 1 has an inner cavity that fits the inner cap 3, but the inner diameter of the cap 11 is smaller than the outer diameter of the inner cap 3. The operator can point the cap opening of the cap 11 toward the inner cap 3 and press the cap 11 along the axial direction of the bottle body 2 to place the cap 11 on the outside of the inner cap 3. At this time, the cap 11 is deformed under the pressure of the inner cap 3, and the cap 11 is not easy to detach from the inner cap 3.
[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
