Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a composite bottle cap that can be opened by pressing. Background Art

[0002] The bottle cap is an important packaging structure used to seal the bottle. Common bottle caps seal or open the bottle through threads that match the bottle mouth. This type of bottle cap is convenient for repeated sealing and opening of the bottle, improving the convenience and sealing of the bottle packaging. However, the threaded bottle cap is also easily opened by children and other immature people. If the bottle contains medicines, cosmetics, detergents, disinfectants and other products, there will be safety hazards if the packaging of these products is accidentally opened by children. Although children will be supervised by special people, negligence is inevitable. Therefore, adding a structure to prevent accidental opening in the bottle or bottle cap can effectively avoid the above safety hazards.

[0003] The Chinese patent with publication number CN114275348A discloses an anti-misopening medicine bottle, including a bottle body and a bottle cap, wherein a bottle mouth with a reduced diameter is connected to the top of the bottle body, the bottle cap is screwed on the bottle mouth, a memory metal strip is connected to the inner surface of the bottle cap, the memory metal strip extends downward into the bottle body, the lower part of the memory metal strip is bent toward the bottle shoulder between the bottle body and the bottle mouth, and the lower part of the memory metal strip is pressed against the inner surface of the bottle shoulder; the above-mentioned anti-misopening medicine bottle cannot be opened because the memory metal is in a bent state under normal temperature conditions to constrain the bottle body and the bottle cap, and when the medicine bottle needs to be opened, the memory metal can be heated and straightened by hot water heating or other methods, but it takes a certain amount of time for the heat to be transferred to the memory metal and straighten it during heating, resulting in low efficiency in opening the medicine bottle, and medicines are usually not suitable for contact with high temperatures, otherwise it is easy to reduce the efficacy or even fail, so the above-mentioned bottle body and bottle cap matching scheme still has room for improvement.

[0008] As a further technical solution of the utility model, a plurality of the locking grooves are distributed in a ring shape along the outer top edge of the inner cover body, each of the locking grooves extends from top to bottom, and the inner diameter of the locking grooves gradually decreases from top to bottom.

[0009] As a further technical solution of the utility model, an anti-skid pattern is arranged around the top edge of the outer side of the outer cover body, and the anti-skid pattern is composed of a plurality of anti-skid grooves.

[0010] As a further technical solution of the utility model, the outer bottom edge of the outer cover body is folded outward to form a curled edge.

[0011] As a further technical solution of the utility model, an annular fixing groove is provided at the top of the inner side of the inner cover body, and a sealing gasket is embedded in the fixing groove.

[0012] As a further technical solution of the utility model, a pin hole is provided on the top of the outer cover body, a fixed pin is provided on the pin hole, the bottom of the fixed pin abuts against the top of the outer side of the inner cover body, a plurality of buckles extending obliquely upward are provided on the surface of the fixed pin, and a pull ring is provided on the top of the fixed pin.

[0013] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0020] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0021] like Figure 1-3 As shown, a press-to-open composite bottle cap comprises an outer cover body 1 and an inner cover body 2, wherein the outer cover body 1 is sleeved on the outer surface of the inner cover body 2, and a gap is provided between the outer cover body 1 and the inner cover body 2 to allow mutual movement, a bottle cap opening 3 is provided at the bottom of the outer cover body 1 and the inner cover body 2, and an internal thread 21 is provided on the inner side of the inner cover body 2; a pressure spring 4 is provided between the inner top of the outer cover body 1 and the outer top of the inner cover body 2, a plurality of locking grooves 22 are provided at the outer top of the inner cover body 2, a plurality of locking protrusions 11 matching the locking grooves 22 are provided at the inner top of the outer cover body 1, and a limiting protrusion 12 abutting against the bottom of the inner cover body 2 is provided around the inner bottom of the outer cover body 1.

[0022] The composite bottle cap of the utility model has the function of preventing accidental opening. The composite bottle cap is fixed to each other by the inner thread 21 and the thread matching the bottle mouth to seal the bottle. When the composite bottle cap seals the bottle and is in a reset state, the bottom edge of the inner cover body 2 abuts against the limiting convex ring 12 under the elastic force of the pressure spring 4 to prevent the outer cover body 1 and the inner cover body 2 from being separated from each other. A plurality of locking protrusions 11 are located above the locking grooves 22. When the composite bottle cap is twisted, the torsion force acts on the outer cover body 1. Since there is no mutually locking structure between the outer cover body 1 and the inner cover body 2, the outer cover body 1 can only be rotated and the composite bottle cap cannot be twisted open. The bottle is opened; when the bottle needs to be opened, the outer cover body 1 is pressed to move it downward and the pressure spring 4 is compressed, so that the locking protrusions 11 enter the locking grooves 22 one by one and bite each other, so that the outer cover body 1 and the inner cover body 2 are locked with each other, and the composite bottle cap is in a locked state. At this time, twisting the composite bottle cap can make the inner cover body 2 and the outer cover body 1 rotate synchronously. When the inner cover body 2 rotates, the internal thread 21 cooperates with the thread at the bottle mouth to unscrew the composite bottle cap, thereby realizing opening the bottle. After the composite bottle cap is unscrewed, the pressing pressure is cancelled, and the pressure spring 4 releases the elastic potential energy to restore the composite bottle cap to a reset state.

[0023] The composite bottle cap of the utility model can be unscrewed through two steps of pressing and rotating, and continuous pressure needs to be applied during the unscrewing process, which increases the difficulty of unscrewing the composite bottle cap. It is difficult for children and other mentally immature people to independently implement the above-mentioned method of unscrewing the composite bottle cap, thereby preventing the composite bottle cap from being opened by mistake and improving the safety of the bottle packaging matched with the composite bottle cap.

[0024] It should be noted that the outer cover body 1 and the inner cover body 2 are preferably made of metal materials such as aluminum and tinplate to form a composite bottle cap made of metal material, which can improve the sealing of the composite bottle cap, and the metal material has good elasticity and mechanical strength, improves the structural stability of the composite bottle cap, and can avoid the composite bottle cap from producing irreversible deformation after being pressed and rotated to open or close for many times, thereby improving the service life of the composite bottle cap; in addition, during the production process of the composite bottle cap, the internal thread 21 on the inner side of the inner cover body 2 can be formed by a common metal bottle cap rolling process, and the locking groove 22 and the locking protrusion 11 can be formed by intermittent molding through a common metal bottle cap molding process, and the outer cover body 1 after the locking protrusion 11 is formed is sleeved on the surface of the inner cover body 2 after the internal thread 21 and the locking groove 22 are formed, and then the surface of the outer cover body 1 is rolled by a rolling process to form a limiting convex ring 12 on its inner side, thereby completing the processing and production process of the composite bottle cap.

[0025] To sum up, the composite bottle cap of the utility model uses the pressure spring 4 to make the outer cover body 1 and the inner cover body 2 unlocked from each other in the reset state, and the torque when twisting the composite bottle cap cannot act on the inner cover body 2 to make the composite bottle cap unable to be unscrewed. It is necessary to press the outer cover body 1 downward to move it until the locking protrusion 11 and the locking groove 22 engage with each other so that the composite bottle cap is in a locked state before it can be unscrewed. The composite bottle cap needs to continuously apply pressure during the unscrewing process, which increases the difficulty of unscrewing the composite bottle cap, thereby avoiding the composite bottle cap from being opened by mistake and improving the safety of the bottle packaging matched with the composite bottle cap.

[0026] like Figure 1 , 2 As shown, as one of the preferred embodiments of the utility model, a spring limiting hole 23 is provided at the top of the outer side of the inner cover body 2, and the bottom of the pressure spring 4 abuts against the bottom of the spring limiting hole 23; a spring limiting protrusion 13 is provided at the top of the inner side of the outer cover body 1, and the top of the pressure spring 4 is sleeved on the outer surface of the spring limiting protrusion 13; the inner diameter of the spring limiting hole 23 is slightly larger than the outer diameter of the pressure spring 4, and the outer diameter of the spring limiting protrusion 13 is slightly smaller than the inner diameter of the pressure spring 4. The spring limiting hole 23 and the spring limiting protrusion 13 can limit the bottom and top of the pressure spring 4 respectively, to prevent the top or bottom of the pressure spring 4 from sliding horizontally when the pressure spring 4 is compressed and being placed horizontally between the outer cover body 1 and the inner cover body 2, resulting in the inability to unscrew the composite bottle cap by squeezing the outer cover body 1 to compress the pressure spring 4.

[0027] like Figure 3 As shown, as one of the preferred embodiments of the utility model, a plurality of locking grooves 22 are distributed in a ring shape along the outer top edge of the inner cover body 2, each locking groove 22 extends from top to bottom, and the inner diameter of the locking groove 22 gradually decreases from top to bottom; the cross-section of the locking groove 22 is triangular so that the side slopes on both sides, the shape of the locking protrusion 11 matches the locking groove 22, the caliber of the top of the locking groove 22 is larger, and the bottom of the locking protrusion 11 is a sharp corner. In the process of pressing the outer cover body 1 to move it downward, the locking protrusion 11 can better enter the locking groove 22 through the bottom and completely slide into the locking groove 22 through the slopes on both sides. When unscrewing or tightening the composite bottle cap, there is no need to spend a lot of time to align the locking protrusion 11 with the locking groove 22, thereby improving operating efficiency.

[0028] like Figure 1-3As shown, as one of the preferred embodiments of the utility model, an anti-slip pattern 14 is arranged around the outer top edge of the outer cover body 1, and the anti-slip pattern 14 is composed of a plurality of anti-slip grooves 141; the anti-slip pattern 14 can increase the friction resistance on the surface of the outer cover body 1, thereby making it easier to unscrew or tighten the composite bottle cap by twisting it, and a plurality of inwardly recessed anti-slip grooves 141 are formed by intermittent molding through the common molding process of metal bottle caps, and when the anti-slip grooves 141 are formed, a plurality of raised locking protrusions 11 are formed on the inner side of the outer cover body 1, and the anti-slip pattern 14 and the locking protrusions 11 are obtained by the same processing step, which can improve the processing efficiency of the composite bottle cap.

[0029] like Figure 1-3 As shown, as one of the preferred embodiments of the utility model, the outer bottom edge of the outer cover body 1 is folded outward to form a curling edge 15; since the outer cover body is made of metal material, the edge of the bottle cap mouth 3 is usually sharp and easy to cut the human body. After the utility model folds the edge of the bottle cap mouth 3 outward to form the curling edge 15 through the common metal bottle cap curling process, the edge of the bottle cap mouth 3 will become rounded and not easy to cut the human body.

[0030] like Figure 1 , 2 As shown, as one of the preferred embodiments of the utility model, an annular fixing groove 24 is provided on the inner top of the inner side of the inner cover body 2, and a sealing gasket 25 is embedded in the fixing groove 24; the sealing gasket 25 is preferably made of a soft material with good resilience such as silicone. After the composite bottle cap is tightened, the sealing gasket 25 abuts against the edge of the bottle mouth of the bottle to improve the sealing of the bottle packaging. The fixing groove 24 is used to clamp the sealing gasket 25 to prevent the sealing gasket 25 from falling off from the composite bottle cap.

[0031] like Figure 4 As shown, as a second preferred embodiment of the present invention, a latch hole 16 is penetrated at the top of the outer cover body 1, and a fixed latch 5 is penetrated at the latch hole 16, and the bottom of the fixed latch 5 abuts against the outer top of the inner cover body 2. A plurality of buckles 51 extending obliquely upward are provided on the surface of the fixed latch 5, and a pull ring 52 is provided on the top of the fixed latch 5; the fixed latch 5 can be used as a fixing structure before the composite bottle cap is opened for the first time, and the fixed latch 5 is preferably made of plastic material. After the composite bottle cap is fixed to the bottle, the fixed latch 5 is inserted into the composite bottle cap through the latch hole 16. At this time, the uppermost buckle 51 of the fixed latch 5 abuts against the inner top of the outer cover body 1, and the bottom of the fixed latch 5 abuts against the outer top of the inner cover body 2, thereby fixing the outer cover body 1 and the inner cover body 2. When it is necessary to unscrew the composite bottle cap, a finger is inserted into the pull ring 52 to pull out the fixed latch 5, so that the outer cover body 1 can be moved downward by pressing.

[0032] It should be noted that since the buckle 51 extends upward at an angle, when the fixed latch 5 is inserted into the latch hole 16, the buckle 51 abuts against the outer top of the outer cover body 1 and bends upward so that the fixed latch 5 can be smoothly inserted into the latch hole 16 and the fixed latch 5 remains structurally intact. When the fixed latch 5 is pulled out, the buckle 51 collides with the inner top of the outer cover body 1 and bends downward or is broken, destroying the structure of the fixed latch 5. The user can judge whether the bottle packaging has been opened by observing the integrity of the fixed latch 5 structure.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
