Description

Technical Field

[0001] This utility model relates to the field of container technology. Specifically, it relates to a bottle cap and a bottle. Background Technology

[0002] Bottle caps with direct drinking spouts often employ a one-time break design to easily identify whether they have been opened and whether someone else has been drinking from the spout. This single break structure allows users to easily determine the cap's status. However, if the break is too long, it requires more force to open the bottle; conversely, if the break is too short, it is more susceptible to breakage during transport due to vibration, thus failing to effectively determine if the cap is open. Utility Model Content

[0003] The purpose of this invention is to provide a bottle cap and bottle that solves the problem of difficulty in judging the usage status of the drinking spout.

[0004] A first aspect of this utility model provides a bottle cap, comprising: A bottom cap has a snap-fit ​​end. A recess is formed on the snap-fit ​​end. Opposite to the snap-fit ​​end, a mounting end is formed on the bottom cap that can be detachably attached to the bottle neck.

[0005] An upper cover is rotatably disposed on a lower cover along a pivot, such that the upper cover can rotate from a first position away from the fastening end to a second position capable of fastening to the fastening end.

[0006] A safety buckle has an extending direction, with its two ends connected to a lower cover and an upper cover respectively along the extending direction. The connection points between the two ends and the upper and lower covers are surface connections. The safety buckle includes a connection point in the middle of the extending direction, the cross-section of which is smaller than the cross-sections of the two ends of the safety buckle, so that the connection point can break when the upper cover rotates from a second position to a first position. The safety buckle is made of a breakable material with a predetermined elastic deformation.

[0007] A second aspect of this invention provides a bottle comprising a bottle mouth capable of being fitted with an assembly end of a bottle cap according to this invention.

[0008] The following text will further explain the characteristics, technical features, advantages, and implementation methods of the bottle cap and bottle in a clear and easy-to-understand manner, with the aid of accompanying drawings. Attached Figure Description

[0017] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of the present utility model are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0018] In this document, "illustrative" means "serving as an example, illustration, or description," and any illustrations or embodiments described herein as "illustrative" should not be construed as a more preferred or advantageous technical solution. For the sake of brevity, each figure only schematically shows the parts relevant to this exemplary embodiment, and they do not represent the actual structure or true proportions of the product.

[0019] In one embodiment of this utility model, such as Figure 1 As shown, a bottle cap is provided, comprising: a lower cap 10, an upper cap 20, and a safety buckle 30. The lower cap 10 has a snap-fit ​​end. A recess 11 is formed on the snap-fit ​​end. Opposite to the snap-fit ​​end, a mounting end is formed on the lower cap 10 that is detachably attachable to the bottle neck.

[0020] like Figure 1 As shown, the upper cover 20 is rotatably disposed on the lower cover 10 along a pivot, so that the upper cover 20 can be positioned from a first position away from the fastening end (e.g., Figure 1The position of the top cover 20 shown) after rotation is in a second position that can be fastened to the fastening end (as shown). Figure 2 (The position of the upper cover 20 shown in the figure). A drinking spout 16 is formed at the top of the upper cover 20 at the position shown in the figure, so that drinking can be done through the drinking spout 16 after the upper cover 20 is opened. The connection between the lower cover 10 and the upper cover 20 is made of a flexible connecting plastic sheet 50, so that the upper cover 20 can be flipped up from the lower cover 10.

[0021] like Figure 2 , 5 As shown in Figure 6, the safety buckle 30 has an extending direction. Both ends of the safety buckle 30 along this extending direction are connected to the lower cover 10 and the upper cover 20, respectively. The connection points between its two ends and the upper cover 20 and the lower cover 10 are surface connections, as shown in Figure 6. Figure 8 As shown, multiple connection points 36 are arranged circumferentially along the safety buckle. There can be three connection points as shown, or two or more. A void structure 37 exists between two connection points 36. The safety buckle 30 includes a connection point in its middle extending direction. The cross-section of the connection point is smaller than the cross-sections at both ends of the safety buckle 30, so that when the upper cover 20 rotates from the second position to the first position, the connection point of the safety buckle 30 can break (e.g., ...). Figure 3 (As shown in the diagram). The safety buckle 30 is made of a fragile material with a set elastic deformation. Specific materials can include PP, PE, PC, ABS, etc.

[0022] like Figure 2 In the middle, before the fixing ring 31 and connecting post 32 of the safety buckle 30 break, the fixing ring 31 of the safety buckle 30 is located Figure 2 The position of A in the middle. For example... Figure 3 As shown, when the upper cover 20 is flipped up along direction C, and when the safety buckle 30 breaks, the fixing ring 31 of the safety buckle 30 will fall into the bottom of the recess 11 in the lower cover 10 after it is separated from the connecting post 32, that is, it will move from position A to position B, while the upper part of the safety buckle 30 will remain in the upper cover mounting hole 21 of the upper cover 20.

[0023] Therefore, as Figure 4 As shown, area 23 of the upper cap and area 15 of the lower cap can be made of transparent plastic. Therefore, after the cap is opened, the retaining ring 31 will fall into the corresponding area 23 of the upper cap and area 15 of the lower cap. If the user sees the retaining ring 31 in area 23 of the upper cap and area 15 of the lower cap, it means that the upper cap has been opened. To make the user's identification more intuitive, the retaining ring 31 of the safety buckle 30 can be made of various colors, such as red, orange, or yellow. This allows the user to determine whether the bottle has been opened by judging the status of the safety buckle, making it easier to determine the bottle's open status.

[0024] like Figure 2 , 5As shown in Figures 6 and 8, in another embodiment of this utility model, the safety buckle 30 has a first fixed end and a second fixed end along its extending direction. The first fixed end is connected to the lower cover 10. The second fixed end is connected to the upper cover 20.

[0025] like Figure 2 , 5 As shown in Figure 6, the recessed portion 11 is a concave hole or an annular hole. A lower inner wall protrusion 12 is formed on the hole wall of the concave hole or on the outer side of the hole wall of the annular hole. The lower inner wall protrusion 12 has an arc-shaped surface or a straight surface in the direction facing the bottom of the concave hole or annular hole.

[0026] like Figure 2 , 5 As shown in Figures 6 and 8, the first fixed end is a fixing ring 31. The fixing ring 31 corresponds to the shape of the recess or annular hole so that the fixing ring 31 can be assembled into the recess or annular hole along the axis. Wherein, when the recess is an annular hole, an annular post 11 is formed in the center of the annular hole.

[0027] like Figure 2 , 5 As shown in Figures 6 and 8, a lower protrusion 34 is formed outward on the outer side of the fixing ring 31. The lower protrusion 34 has a lower stepped annular surface facing the second fixing end. The lower protrusion 34 has an outward inclined surface in the direction away from the first fixing end. When the fixing ring 31 is inserted into the concave hole or annular hole, the outward inclined surface of the lower protrusion 34 makes it easier for the fixing ring 31 to be inserted into the concave hole. When the top cover is opened, the lower stepped annular surface abuts against the arcuate surface or straight surface of the lower inner wall protruding ring 12.

[0028] like Figure 2 , 5 As shown in Figures 6 and 8, in another embodiment of this utility model, after the upper cover 20 and the lower cover 10 are fastened together, an upper cover mounting hole 21 is formed at a position corresponding to the recess 11 of the lower cover 10. An upper inner wall protrusion ring 23 is formed on the hole wall of the upper cover mounting hole 21. The upper inner wall protrusion ring 23 has an arc-shaped surface or a straight surface in the direction facing the bottom of the upper cover mounting hole 21.

[0029] like Figure 2 , 5 As shown in Figures 6 and 8, the second fixed end is a connecting post 32. The shape of the connecting post 32 corresponds to the upper cover mounting hole 21, so that one end of the connecting post 32 can be axially positioned within the upper cover mounting hole 21. The connecting post 32 can abut against the ring post 11, so that when the safety buckle 30 is positioned between the lower cover 10 and the upper cover 20, especially during the transportation of bottled water, because the ring post 11 supports the bottom of the connecting post 32 in the illustrated position, therefore, as shown... Figure 5As shown, the connecting post 32 and the fixing ring 31 are not prone to tensile forces, making it difficult for the connecting post 32 to detach from the fixing ring 31. At the same time, the ring post 11 also makes it easier for the safety buckle 30 to abut against the ring post 11 during installation, thus preventing it from falling off.

[0030] like Figure 2 , 5 As shown in Figures 6 and 8, the safety buckle 30 has an upper protrusion 33 formed on the outer circumference of one end of the connecting post 32 that can be disposed in the upper cover mounting hole 21. The upper protrusion 33 has an upper stepped annular surface in the direction facing the first fixed end. The upper protrusion 33 is an inclined surface that slopes outward in the direction away from the first fixed end. When the connecting post 32 is assembled in the upper cover mounting hole 21, the upper stepped annular surface abuts against the arcuate surface or straight surface of the upper inner wall protruding ring 23.

[0031] Therefore, when the lower cover 20 is flipped up from the lower cover 10, the fixing ring 31 and the connecting post 32 cannot be detached from the fixing ring 31 and the upper cover assembly hole 21 under the action of the corresponding lower protrusion 34 and upper protrusion 33. The middle part of the connection between the fixing ring 31 and the connecting post 32 is torn off, so the fixing ring 31 falls into the bottom of the annular cavity. At the same time, due to the action of the lower protrusion 34 and the upper protrusion 33, the fixing ring 31 and the connecting post 32 are prevented from falling outward.

[0032] like Figure 2 , 5 As shown in Figure 6, the outer circumferential surface of the other end of the connecting post 32 and the inner wall of the fixing ring 31 are connected by a connector. The connectors are evenly or unevenly distributed along the outer circumferential surface of the connecting post 32.

[0033] like Figure 2 , 5 As shown in Figure 6, in another embodiment of this utility model, the connector is one or more connectors. The cross-section at the intersection of the connector and the fixing ring 31 is polygonal, circular, or elliptical.

[0034] like Figure 2 , 5 As shown in Figure 6, when there are multiple connectors, they are arranged at 120° intervals around the outer circumferential surface of the connecting post 32. The cross-section of the connector gradually decreases from the connecting post 32 to the inner wall of the connecting ring. The connector is inclined towards the second fixed end.

[0035] In another embodiment of this utility model, the bottom of the upper cover mounting hole 21 is a flat or curved surface. The end of the connecting post 32 opposite to the upper cover mounting hole 21 is a flat or curved surface corresponding to the bottom of the upper cover mounting hole 21. A tapered hole is formed at the end of the connecting post 32 facing the annular hole. The tapered hole can abut against the central region of the annular hole. The central region of the annular hole is a flat or curved surface.

[0036] In another embodiment of this utility model, the upper cover 20 and the lower cover 10 have an opening and closing side. The upper cover 20 forms an opening protrusion on the opening and closing side. The opening protrusion includes a contact surface that can face the lower cover 10.

[0037] In another embodiment of this utility model, the lower cover 10 can form a drinking hole 16 at one end facing the upper cover 20. The portion where the hole wall of the drinking hole 16 meets the opening forms a sealing hole wall.

[0038] The upper cover 20 includes a top cover end facing away from the lower cover 10. The outer surface of the top cover end forms a top cover surface. A protruding plug 22 is formed on the top cover surface in a direction that allows it to face the lower cover 10. The protrusion direction of the plug 22 is perpendicular to the top cover surface. The outer circumference of the plug 22 includes a first sealing annular surface.

[0039] When the upper cover 20 is fastened to the lower cover 10, the first sealing ring surface of the plug 22 can abut against and seal against the sealing hole wall, so that the plug 22 seals the opening of the drinking hole 16.

[0040] like Figure 7 As shown, in another embodiment of this utility model, the bottle cap includes a flexible wrapping ring 13 extending into the orifice in a direction opposite to the orifice wall. The flexible wrapping ring 13 gradually decreases in diameter from the orifice into the orifice. The flexible wrapping ring 13 is achieved through a thin plastic layer (the thinner the flexible plastic, the easier it is to deform).

[0041] like Figure 7 As shown, a second sealing ring 14 is formed on the direction where the stopper 22 is adjacent to the first sealing ring surface and away from the top cover surface. When the upper cover 20 is fastened to the lower cover 10, the flexible wrapping ring 13 wraps around and seals the ring surface of the second sealing ring. This results in a better seal for the bottle opening.

[0042] The opening of the drinking hole 16 is inclined inwards to form an inclined opening surface. The outer circumference of the seal forms an opening step surface corresponding to the inclined opening surface. When the upper cover 20 is fastened to the lower cover 10, the opening step surface can abut against the inclined opening surface to form a seal.

[0043] In another embodiment of this invention, a top recess is formed on the top cover surface at a position corresponding to the sealing plug 22. The top recess has an inner annular cavity. A top convex ring is formed within the inner annular cavity.

[0044] The bottle cap also includes a top cap seal 40, which includes an outer peripheral surface. A sealing protrusion 41 is formed on the outer peripheral surface. The top cap seal 40 is detachably disposed within a top recess such that the outer peripheral surface of the top cap seal 40 can be opposed to the inner annular cavity and the sealing protrusion 41 and the top protrusion 25 are pressed together to form a sealing annular surface.

[0045] In another aspect, this invention provides a bottle comprising a bottle mouth capable of being fitted with the fitting end of a bottle cap of this invention.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
