Description

Technical Field

[0001] The present invention relates to the technical field of bottle caps, and particularly relates to a bottle cap structure and an opening method thereof. Background Art

[0002] A bottle cap is an important component for sealing a bottle. Depending on different uses, there are various shapes and operation methods. It is not only a key link in food and beverage packaging but also the part where consumers first come into contact with the product. The main function of the bottle cap is to maintain the airtight performance of the contents and has the characteristics of anti-theft opening and safety, so it is widely used in various bottled products.

[0003] The lids of existing beverage bottles generally have a relatively simple structure. When sealing, the lid body and the fixing ring are connected by multiple break points. When the bottle needs to be opened, only by turning the lid body can the lid body be separated from the fixing ring. After the lid body is removed, the bottle mouth is opened. This kind of bottle cap has simple opening steps but is also prone to accidental opening of the lid body under torsion, resulting in limited sealing effect. Summary of the Invention

[0004] The purpose of the present invention is to provide a bottle cap structure and an opening method thereof to solve the problem that the bottle cap in the prior art is prone to accidental opening under torsion. The bottle cap structure of the present invention can effectively prevent the accidental opening of the bottle cap and make the sealing effect of the bottle better.

[0005] A bottle cap structure provided by the present invention includes

[0006] A first lid body, a first abutting portion is provided at the top of the first lid body and a fixing ring is provided at the bottom end of the first lid body.

[0007] A second lid body, a second abutting portion and a clamping portion are respectively provided at the top end and the bottom end of the second lid body. The first lid body is sleeved outside the second lid body.

[0008] In the closed state, the first abutting portion abuts on the upper side of the second abutting portion, and the fixing ring is stuck outside the clamping portion and makes the clamping portion tightly clamped on the bottle mouth.

[0009] In the opened state, the first abutting portion and the second abutting portion are arranged in a misaligned and nested manner, and the first lid body presses the fixing ring down to the lower side of the clamping portion and makes the clamping portion release the bottle mouth.

[0010] As a preferred solution of the present invention, the bottom end of the first lid body and the fixing ring are connected by multiple break points.

[0011] As a preferred embodiment of the present invention, the first abutting portion includes a plurality of first limiting blocks, and the plurality of first limiting blocks are arranged in a circular pattern centered on the axis of the first cover body on the lower side of the top surface of the first cover body. A first limiting groove is formed between two adjacent first limiting blocks.

[0012] The second abutting block includes a plurality of second limiting blocks having the same number as the first limiting blocks. The plurality of second limiting blocks are arranged in a circular pattern centered on the axis of the second cover body on the upper side of the top surface of the second cover body. A second limiting groove is formed between two adjacent second limiting blocks.

[0013] The first limiting block can be embedded in the second limiting groove, and the second limiting block can be embedded in the first limiting groove.

[0014] As a preferred embodiment of the present invention, the first limiting block is arc-shaped, the second limiting block is arc-shaped, and the central angle corresponding to the first limiting block is equal to the central angle corresponding to the second limiting block.

[0015] As a preferred embodiment of the present invention, both the first limiting block and the second limiting block are three, and the central angle corresponding to the first limiting block and the central angle corresponding to the second limiting block are both 60°.

[0016] As a preferred embodiment of the present invention, the clamping portion includes a plurality of elastic racks. The plurality of elastic racks are connected to the top surface of the second cover body and extend downward. The plurality of elastic racks are arranged in a circular pattern. When the fixing ring is clamped outside the plurality of elastic racks, the inner sides of the bottoms of the plurality of elastic racks are clamped tightly on the bottle mouth. When the fixing ring falls to the lower side of the plurality of elastic racks, the plurality of elastic racks release the bottle mouth.

[0017] As a preferred embodiment of the present invention, a clamping ring is provided on the inner side of the fixing ring, and the inner side of the clamping ring has an inclined surface, and the inclined surface can be attached to the outer side surface of the bottom end of the elastic rack.

[0018] As a preferred embodiment of the present invention, a clamping hook is provided on the inner side of the bottom end of the elastic rack, and the clamping hook can be clamped on the bottle mouth.

[0019] As a preferred embodiment of the present invention, it further includes a lighting component. The lighting component includes a housing, a battery component, a lamp bead, and a shrapnel. The battery component is installed in the housing, the lamp bead is connected to the battery component, and the shrapnel is connected to the negative electrode of the battery component. In the closed state, the shrapnel is clamped between the first abutting portion and the second abutting portion. When the first abutting portion and the second abutting portion are misaligned, the shrapnel connects the circuit between the battery component and the lamp bead.

[0020] The present invention also provides a method for opening the bottle cap structure described above, which is characterized by including the steps of:

[0021] Rotate the first cap body relative to the second cap body so that the first limiting block is arranged on the upper side of the second limiting groove, and the bottom end of the first cap body is broken and separated from the fixing ring;

[0022] Press the first cap body downward relative to the second cap body so that the first limiting block is embedded in the second limiting groove, and the fixing ring moves to the lower side of the clamping portion and makes the clamping portion release the bottle mouth.

[0023] Compared with the prior art, the present invention has the following positive effects:

[0024] The bottle cap structure provided by the present invention includes a first cap body and a second cap body. The first cap body is sleeved outside the second cap body. The top of the first cap body is provided with a first abutting portion, and the bottom end of the first cap body is provided with a fixing ring. A second abutting portion and a clamping portion are respectively arranged at the top end and the bottom end of the second cap body. In the closed state, the first abutting portion abuts on the upper side of the second abutting portion, and the fixing ring is stuck outside the clamping portion and makes the clamping portion clamp tightly on the bottle mouth. In the opened state, the first abutting portion and the second abutting portion are arranged in a misaligned and nested manner. The first cap body presses the fixing ring downward to the lower side of the clamping portion and makes the clamping portion release the bottle mouth. When the bottle cap structure in the present invention changes from the closed state to the opened state, the second cap body is clamped tightly on the bottle mouth through the clamping portion. The first cap body needs to rotate left and right relative to the second cap body first to make the first abutting portion misaligned and arranged on the upper side of the second abutting portion, and then press the first cap body downward to make the first abutting portion and the second abutting portion misaligned and nested. At this time, the first cap body presses the fixing ring downward to the lower side of the clamping portion and makes the clamping portion release the bottle mouth, so that the first cap body and the second cap body can be taken off from the bottle mouth as a whole, thereby opening the bottle cap. Compared with the existing bottle cap opening methods, for this bottle cap structure to simultaneously release the first bottle cap and the second bottle cap from the bottle mouth, at least two actions of screwing and pressing the first bottle cap are required. Therefore, the actions for opening the bottle cap are increased, the situation of accidental opening of the bottle cap is prevented, and the sealing effect of the bottle is better.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0035] In the description of the present invention, it should also be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The following further describes in detail the specific implementation manners of the present invention with reference to the drawings.

[0037] Example 1:

[0038] A cap structure provided in this embodiment is as follows Figures 1-7 shown, including a first cap body 1 and a second cap body 2. The first cap body 1 is sleeved outside the second cap body 2. A first abutting portion is provided at the top of the first cap body 1, and a fixing ring 3 is provided at the bottom end of the first cap body 1. A second abutting portion and a clamping portion are respectively provided at the top end and the bottom end of the second cap body 2.

[0039] In the closed state, the first abutting portion abuts on the upper side of the second abutting portion, so that the first cap body has better load-bearing capacity and ensures relative stability between the first cap body 1 and the second cap body 2. The fixing ring 3 is stuck outside the clamping portion and makes the clamping portion tightly clamped on the bottle mouth. In the open state, the first abutting portion and the second abutting portion are arranged in a misaligned and nested manner. The first cap body 1 presses the fixing ring 3 down to the lower side of the clamping portion and makes the clamping portion loosen the bottle mouth.

[0040] When the cap structure in this embodiment changes from the closed state to the open state, the second cap body 2 is tightly clamped on the bottle mouth through the clamping portion. The first cap body 1 needs to rotate left and right relative to the second cap body 2 first, as Figure 6 shown, so that the first abutting portion is misaligned and arranged on the upper side of the second abutting portion, and then press down the first cap body, as Figure 7 shown, so that the first abutting portion and the second abutting portion are arranged in a misaligned and nested manner. At this time, the first cap body 1 presses the fixing ring 3 down to the lower side of the clamping portion and makes the clamping portion loosen the bottle mouth, so that the first cap body and the second cap body can be integrally removed from the bottle mouth, thereby opening the cap.

[0041] Compared with the existing cap opening method, the cap structure of this embodiment needs to release the first cap and the second cap from the bottle mouth at the same time, and at least two actions of twisting and pressing the first cap are required. Therefore, the actions of opening the cap are increased, the situation of accidental opening of the cap is prevented, and the sealing effect of the bottle is better.

[0042] As a preferred implementation, the bottom end of the first cap body 1 and the fixing ring 3 are connected through a plurality of break points 4. The bottom end of the first cap body 1 and the fixing ring 3 are connected in a breakable manner through a plurality of break points 4. When the first cap body is twisted relative to the second cap body, the fixing ring 3 is stuck outside the clamping portion, and the first cap body 1 and the fixing ring 3 are subjected to torsion, and the plurality of break points 4 are broken, so that the first cap body 1 is separated from the fixing ring 3. The irreversible connection between the first cap body 1 and the fixing ring 3 makes the cap structure have an anti-counterfeiting effect, and the cap structure loses its function after being removed from the bottle mouth.

[0043] As a preferred implementation, as Figure 5As shown, the first abutment portion includes a plurality of first limiting blocks 11 , which are arranged in a circular shape with the axis of the first cover body 1 as the center and arranged on the lower side of the top surface of the first cover body 1 , and a first limiting groove 12 is formed between two adjacent first limiting blocks 11 .

[0044] The second abutment block includes a plurality of second limit blocks 21 of the same number as the first limit block 11. The plurality of second limit blocks 21 are arranged in a circle with the axis of the second cover body 2 as the center and are arranged on the upper side of the top surface of the second cover body 2, and a second limit groove 22 is formed between two adjacent second limit blocks 21.

[0045] The first limiting block 11 can be embedded in the second limiting groove 22 , and the second limiting block 21 can be embedded in the first limiting groove 12 .

[0046] In the closed state, the plurality of first limit blocks 11 relatively abut against the upper sides of the plurality of second limit blocks 21 to provide better support for the first cover. When the bottle cap needs to be opened, the first cover is rotated to stagger the first limit blocks 11 and the second limit blocks 21. The first limit blocks 11 correspond to the upper side of the second limit groove 22, and the second limit blocks 21 correspond to the lower side of the first limit groove 12. When the first cover is pressed, the first cover 1 moves downward relative to the second cover, so that the first limit blocks 11 are embedded in the second limit groove 22, and the second limit blocks 21 are embedded in the first limit groove 12.

[0047] As a preferred embodiment, the arc shape of the first limit block 11 and the arc shape of the second limit block 21 are equal in angle to the central angle of the first limit block 11 and the central angle of the second limit block 21. Preferably, the first limit block 11 and the second limit block 21 are equal in size. When the bottle cap is opened, the first limit block 11 is embedded in the second limit groove 22, and the second limit block 21 is embedded in the first limit groove 12, so that the first limit block 11 and the second limit block 21 enclose a complete circular structure, so that the first cover body and the second cover body are mutually limited in the circumferential direction, and when the first cover body is rotated, the second cover body can be removed from the bottle mouth together.

[0048] As a preferred embodiment, Figure 4 As shown, there are three first limit blocks 11 and three second limit blocks 21, and the central angles of the first limit blocks 11 and the second limit blocks 21 are both 60°. In addition, the number of the first limit blocks 11 and the second limit blocks 21 can also be two, four, etc.

[0049] As a preferred embodiment, the snap-in part includes a plurality of elastic rack teeth 23. The plurality of elastic rack teeth 23 are connected to the top surface of the second cover body 2 and extend downward. The plurality of elastic rack teeth 23 are arranged in a circular pattern. When the fixing ring 3 is snapped outside the plurality of elastic rack teeth 23, the inner sides of the bottoms of the plurality of elastic rack teeth 23 are clamped tightly on the bottle mouth. When the fixing ring 3 drops to the lower side of the plurality of elastic rack teeth 23, the plurality of elastic rack teeth 23 release the bottle mouth. The elastic rack teeth 23 are elastic, so that when the fixing ring 3 is snapped outside the plurality of elastic rack teeth 23, it can exert an inward squeezing force on the bottom ends of the elastic rack teeth 23, thereby clamping the inner sides of the bottoms of the plurality of elastic rack teeth 23 tightly on the bottle mouth. When the fixing ring 3 drops to the lower side of the plurality of elastic rack teeth 23, the plurality of elastic rack teeth 23 are not under the pressure of the fixing ring 3 and are in a natural unfolded state, so that the plurality of elastic rack teeth 23 release the bottle mouth. The diameter of the circle formed by enclosing when the inner sides of the bottoms of the plurality of elastic rack teeth 23 are clamped tightly on the bottle mouth is smaller than the diameter of the circle formed by enclosing when the plurality of elastic rack teeth 23 release the bottle mouth. When the plurality of elastic rack teeth 23 are in a natural unfolded state without the pressure of the fixing ring 3, the diameter of the circle formed by enclosing the plurality of elastic rack teeth 23 is larger than the inner diameter of the fixing ring 3, so that when the first cover body is pulled, the second cover body can be driven to disengage from the bottle mouth together, thereby opening the bottle mouth.

[0050] As a preferred embodiment, a snap ring is provided inside the fixing ring 3. The inner side of the snap ring has an inclined surface 31. The inclined surface 31 can be attached to the outer side surface of the bottom end of the elastic rack tooth 23. The inclined surface 31 is inclined from the inside to the outside from top to bottom to apply a uniform inward squeezing force to the bottom end of the elastic rack tooth 23. The outer side surface of the elastic rack tooth 23 is inclined.

[0051] As a preferred embodiment, a catch 24 is provided inside the bottom end of the elastic rack tooth 23. The catch 24 can be caught on the bottle mouth. The catch 24 enables the elastic rack tooth 23 to be firmly clamped on the bottle mouth, so that the second cover body can be stably fixed on the bottle mouth.

[0052] As a preferred embodiment, the bottle cap structure of this embodiment further includes a lighting component, which includes a housing, a battery component, a lamp bead, and a shrapnel. The battery component is installed in the housing. The lamp bead is connected to the battery component. The shrapnel is connected to the negative electrode of the battery component. In the closed state, the shrapnel is stuck between the first abutting portion and the second abutting portion. When the first abutting portion and the second abutting portion are misaligned, the shrapnel connects the circuit between the battery component and the lamp bead. The lighting component is arranged in the first cover body and the second cover body. Preferably, openings are provided on the top surfaces of the first cover body and the second cover body, and the lighting component is embedded at the openings and seals the openings. When the first cover body is rotated, the first abutting portion and the second abutting portion are misaligned, and the shrapnel resets to connect the circuit between the battery component and the lamp bead, and the lamp bead emits light, simultaneously prompting the operator that the first cover body rotates relative to the second cover body. A speaker can also be arranged in the housing, and the speaker is connected to the battery component, so that when the first abutting portion and the second abutting portion are misaligned, the shrapnel connects the circuit between the speaker and the lamp bead, thereby playing music. The lighting component can adopt an existing structure.

[0053] In addition, when the bottle cap structure does not have a lighting component, the top surfaces of the first cover body and the second cover body can both be set as sealed planes without openings.

[0054] The above-mentioned "inner side" refers to the side close to the axes of the first cover body and the second cover body, and the "outer side" refers to the side far from the axes of the first cover body and the second cover body.

[0055] This embodiment also provides a method for opening the bottle cap structure, including the steps:

[0056] Rotate the first cover body 1 relative to the second cover body 2 so that the first limiting block 11 is arranged on the upper side of the second limiting groove 22, and the bottom end of the first cover body 1 is broken and separated from the fixing ring 3;

[0057] Press the first cover body 1 downward relative to the second cover body 2 so that the first limiting block 11 is embedded in the second limiting groove 22, and the fixing ring 3 moves to the lower side of the clamping portion and releases the clamping portion from the bottle mouth.

[0058] Existing bottle caps are generally opened by directly twisting. The bottle cap structure of this embodiment uses a two-stage opening method. When the bottle cap is in a sealed state, twist the first cover body so that the bottom end of the first cover body 1 is broken from the fixing ring 3, and the first limiting block 11 is staggered from the second limiting block. At this time, the lighting component is turned on, and light will emit inside the first cover body. At this time, the fixing ring 3 is fastened outside the clamping portion, and the bottle cap is not opened and is still in a sealed state. When it needs to be opened, press or strike the first cover body again. The fixing ring 3 moves to the lower side of the clamping portion, and the multiple elastic racks of the clamping portion are in a natural unfolded state. At this time, the bottle cap is really opened.

[0059] The above are only the preferred embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art in this technical field can make several variations and improvements without departing from the creative concept of the present invention, and all of them should be covered within the protection scope of the present invention.
