Description

Beverage bottle cap

Technical Field

Background

The beverage bottle cap is designed to be a structure capable of storing beverage raw materials (hereinafter referred to as raw materials), and the raw materials in the bottle cap are mixed with water in the beverage bottle before drinking, so that the drinking taste of the beverage can be improved. Techniques for storing raw materials by providing a storage space in a beverage bottle cap have been studied and used at present.

Sealing of the material in the beverage bottle cap is typically achieved by providing a storage cavity in the beverage bottle cap, and sealing the storage cavity with an aluminium film. Before drinking, the raw materials and water are mixed by puncturing the aluminum film. The raw materials are stored in the beverage bottle cap, so that the beverage bottle cap is required to be well sealed for preventing the raw materials from being affected with damp or spoiled, and the raw materials can smoothly enter the beverage bottle and be mixed with water when the beverage bottle cap is drunk. Because the aluminum film has better elasticity, a certain piercing force is needed to pierce the aluminum film, and furthermore, because the aluminum film has elasticity, the aluminum film is easy to deform and is far away from the pricking pin when the aluminum film is pierced, so that the length of the pricking pin needs to be ensured. The thicker the aluminum film, the greater the required lancing force and the greater the elastic deformation upon lancing.

In order to ensure that the aluminum film can be successfully punctured, the current beverage bottle caps are realized by reducing the thickness of the aluminum film or reducing the sealing strength of the aluminum film and the storage cavity, but the sealing effect is poor, the risk of wetting and deterioration is increased after long-time storage, and if the stored liquid raw materials are very easy to leak, so that the current beverage bottle caps can store solid raw materials and cannot meet the storage requirement of the liquid beverage raw materials.

The specific meaning of the above terms in the present utility model is understood by those of ordinary skill in the art according to the specific circumstances.

As shown in fig. 1-13, the beverage bottle cap comprises a top cap 9, a bottle cap body and a needling member fixed in the bottle cap body.

The bottle cap body comprises an inner barrel 1 and a spiral cap 2 used for being in sealing connection with the beverage bottle, the spiral cap 2 is sleeved outside the inner barrel 1, the upper end of the spiral cap 2 is in sealing connection with the outer wall of the inner barrel 1, and a spiral cap platform 8 is formed at the sealing connection position of the upper end of the spiral cap 2 and the inner barrel 1. The inner wall of the spiral cover 2 is provided with threads matched with the bottle mouth of the beverage bottle, when the bottle is used, the lower end of the inner barrel 1 is inserted into the beverage bottle from the bottle mouth, the spiral cover 2 is connected with the bottle mouth of the beverage bottle, and the lower end of the spiral cover 2 is provided with an anti-theft ring 19. The top cover 9 covers the upper part of the inner cylinder 1.

The needling member is fixed in the inner cylinder 1, the upper and lower ends of the inner cylinder 1 are respectively sealed by an upper membrane 31 and a lower membrane 32, and the inner cylinder 1 is a storage cavity. The upper film 31 and the lower film 32 are preferably made of food-grade aluminum film.

The manner of fixing the needling member in the inner cylinder 1 is as follows: the needling member comprises a pressing plate 4 and a needling cylinder 6 fixed on the lower end surface of the pressing plate 4, and needling 7 is arranged at the bottom of the needling cylinder 6. Spokes 18 are arranged on the periphery of the pressing plate 4, the outer ends of the spokes 18 are connected with the inner wall of the inner cylinder 1, and the needling piece is clamped and fixed in the inner cylinder 1 through the spokes 11; as a preferred embodiment, the spokes 18 may have a spoke nipple 20 provided on the outer periphery thereof, and the spoke nipple 20 is connected to the inner wall of the inner tube 1. The structure that the needling member is fixedly connected with the inner cylinder 1 through the spokes 18 can reduce the downward pressure for separating the needling member from the inner cylinder 1.

The screw cap 2 is fixed in the middle of the inner cylinder 1, so that when the bottle mouth of the beverage bottle is covered by the screw cap 2, the lower end of the inner cylinder 1 can be inserted into the beverage bottle, and the upper end can be used for being connected with the top cap 9.

The upper end face of the spiral cover platform 8 is provided with two symmetrical lower limit pieces 10, the lower limit pieces 10 are higher than the spiral cover platform 8, and a pressing channel 11 is reserved between the lower limit pieces 10. The center of the lower end face of the top cover 9 is provided with a top rod 13, the lower end face of the cover barrel of the top cover 9 is provided with two symmetrical upper limit plates 12, the upper limit plates 12 are opposite to the lower limit plates 10, the opposite faces of the lower limit plates 10 and the upper limit plates 12 are respectively provided with a limit ring 14 or a limit buckle 15, and the limit rings 14 are buckled with the limit buckles 15. When the raw materials in the inner cylinder 1 are mixed into the beverage bottle, the top cover 9 is rotated, the limiting ring 14 and the limiting buckle 15 are separated (the limiting ring 14 and the limiting buckle 15 are made of plastic materials, and the limiting ring 14 and the limiting buckle 15 are deviated in position and separated by rotating the top cover 9, and the limiting buckle 15 can be ejected from the limiting ring 14 by utilizing the elasticity of plastic during separation, or the limiting ring 14 is pulled to be separated when the limiting buckle 15 rotates). By arranging the limiting ring 14 and the limiting buckle 15, the top cover 9 is limited before the beverage is mixed, so that the top cover 9 is prevented from being pressed down and puncturing the lower film of the inner barrel 1. The limiting rings 14 and the limiting buckles 15 are used for limiting the top cover 9 and the inner cylinder 1 to rotate under the action of no external force, and any structure capable of achieving the effect can be used. For example, the limiting ring 14 is in a mouth-shaped structure, the limiting buckle 15 is a bump fixed on the outer surface of the bottom of the upper limiting piece 12, and the bump is just clamped in the mouth-shaped structure when the upper limiting piece 12 and the lower limiting piece 10 are aligned.

The upper limiting piece 12 rotates to be opposite to the pressing-down channel 11, then the top cover 9 is pressed down along the pressing-down channel 11, the top cover 9 is pressed down, meanwhile, the ejector rod 13 pierces the upper film of the inner barrel 1, the pressing plate 4 is pressed down to enable the needling member to integrally press down, during pressing down, the spokes 18 are broken, the needling member moves down and pierces the lower film 32 of the inner barrel 1 after being separated from the constraint of the inner barrel 1, and raw materials of the inner barrel 1 are released and enter the beverage bottle. The upper limit plate 12 is trapezoidal; the lower limit plate 10 has an inverted trapezoid shape, but the shape of the two is not limited to the trapezoid shape. The upper limit plate 12 is ensured to be pressed down by the structural design that the width of the upper limit plate 12 is smaller than that of the pressing down channel 11.

The ejector rod 13 pushes down to pierce the upper film 31, and simultaneously pushes down the needling member, which starts to descend and pierce the lower film 32 upon receiving the pushing down force. Through setting up the acupuncture spare in inner tube 1 to with going up membrane 31 and lower membrane 32 and sealing up inner tube 1, not only can be with the raw materials seal, and when puncture upper membrane 31 and lower membrane 32, the transmission of puncture power can be played to the acupuncture spare of built-in, makes lower membrane 32 puncture more easily, and then can select thicker sealing membrane, better membrane and inner tube 1's cementation intensity, improves sealed effect.

The upper limit plate 12 and the lower limit plate 10 are arranged, and the pressing channel 11 is reserved between the lower limit plates 10, so that the top cover 9 has a certain stroke when being pressed down, and the larger the stroke is, the larger the impact force generated when being pressed down is, so that the upper film 31 and the lower film 32 are more easily pierced. The puncture of the upper film 31 of the inner cylinder 1 is relatively easy, and the upper film 31 has little influence on the release of raw materials in the inner cylinder 1, and only a through hole needs to be punctured. The key to determining whether the material can be released and enter the beverage bottle is whether the lower membrane 32 of the inner cartridge 1 can be successfully pierced. The push rod 13 on the top cover 9 pushes down the pressing plate 4, the stroke of the top cover 9 determines the stroke of the needling cylinder 6, and the inventor needs to ensure the thickness of the aluminum film under the condition that the sealing effect of the inner cylinder 1 is ensured and the sealing can reach the liquid sealing effect through a large amount of experiments, and the aluminum film under the thickness needs to be pierced by the needling cylinder 6 after the stroke of more than 2 cm. The spiral cover 2 is sleeved in the middle of the inner cylinder 1, and the structural design of the lower limit piece 10 and the upper limit piece 12 creates conditions for realizing the stroke, thereby ensuring the impact force of the needling cylinder 6 on the lower film. The extension of the stroke needs to ensure the length of the inner cylinder 1, and meanwhile, the length of the inner cylinder 1 determines the volume of the raw materials which can be stored in the inner cylinder 1, so that the volume of the inner cylinder 1 can be increased and more raw materials can be filled while the stroke is increased.

As one of the preferred schemes, the inner wall of the upper limit plate 12 is provided with a clamping strip, and simultaneously, the outer wall of the inner cylinder 1 and the upper side of the lower limit plate 10 are provided with an anti-falling clamping block 17 clamped with the clamping strip, and the anti-falling clamping block 17 and the clamping strip are at least one, and by arranging the clamping strip and the anti-falling clamping block 17, the top cover 9 and the inner cylinder 1 can be prevented from falling off (falling off from the upper side), and meanwhile, the rotation of the top cover 9 is not influenced. The locking strip is a strip-shaped bulge, and the anti-falling clamping block 17 is any structure capable of limiting the locking strip after the top cover 9 is covered with the inner cylinder 1, such as a strip-shaped bulge, or a lug with a thin upper part and a thick lower part or any bulge structure shown in fig. 5-6.

As one of the preferred schemes, the ejector rod 13 is arranged at the center of the top cover 9, a positioning hole 16 is formed in the center of the pressing plate 4, the diameter of the positioning hole 16 is smaller than that of the ejector rod 13, when the top cover 9 is pressed down, the ejector rod 13 is inserted into the positioning hole 16 in a small amount and limited, and when the top cover 9 is pressed down, the ejector rod 13 is ensured to be vertical, so that the influence of deflection of the ejector rod 13 on the pressing stroke is avoided.

As one of the preferred solutions, the needling drum 6 is provided with a through slot 5, so that the needling drum 6 is of a non-completely enclosed tubular structure, which has very obvious advantages: 1) When the lower membrane 32 is pierced, the notch formed by the through groove 5 plays a role of a diversion channel, and can ensure that all raw materials stored in the inner cylinder 1 can enter the beverage bottle. Moreover, the through groove 5 is arranged, and all raw materials in the inner barrel 1 can enter the beverage bottle through the through groove 5 only by the needle punching barrel 6 penetrating the lower film 32 and slightly penetrating out, and the through groove 5 penetrates through the whole structure of the needle punching barrel 6 and is not limited by the penetration depth of the needle punching barrel 6 (the penetration depth of the needle punching barrel 6 penetrating the lower film 32), namely, all raw materials can enter the beverage bottle no matter the needle punching barrel 6 penetrates and intersects the lower film 32 at any position. If the through groove 5 is not formed, even if the lower membrane 32 can be pierced by the needling drum 6, the raw material in the cavity between the needling drum 6 and the inner cylinder 1 is difficult to enter the beverage bottle. 2) When the inner cylinder 1 is filled with the raw material, the raw material can fill the entire inner cylinder 1 through the through groove 5. According to experimental comparison, if the through groove 5 is not formed in the needling tube 6 to fill raw materials, after the upper film 31 of the inner tube 1 is sealed when the raw materials are filled, when the raw materials are filled into the inner tube 1 (whether liquid raw materials or solid raw materials are filled), the hollow between the needling tube 6 and the inner tube 1 is too small due to the small tube opening of the needling tube 6 and the full sealing structure of the needling tube 6, the filling rate is low, the filling is easy to spill out, the problem that the needling tube 6 is difficult to fill is also existed, and after the through groove 5 is formed, the raw materials can quickly fill the whole inner tube 1 (the needling tube 6 and the hollow between the needling tube 6 and the inner tube 1) when the raw materials are filled, and the filling efficiency is higher.

The through groove 5 preferably extends through the entire needling drum 6, and the technical solution (fig. 13) which is only provided at the lower part of the needling drum 6 cannot escape from the scope of the present utility model.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the utility model as defined by the appended claims.
