Detailed Implementation

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0020] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Throughout the text, the terms “top,” “bottom,” “above,” “below,” and “on top” refer to the relative positions of components of the device, such as the relative positions of the top and bottom substrates within the device. It is understood that the device is multifunctional and independent of its spatial orientation.

[0022] The working surface of this utility model can typically be a plane or a curved surface, and can be inclined or horizontal. For ease of explanation, the embodiment of this utility model is placed on a horizontal surface and used on a horizontal surface, thereby defining "height" and "vertical".

[0023] A specific embodiment of this utility model discloses a multifunctional bottle cap, such as... Figures 1-4 As shown, it includes: The outer cover 1 has a downwardly opening outer cover cavity 101; the top of the outer cover 1 has an injection port 102, which communicates with the outer cover cavity 101; the top of the outer cover 1 has a detachable sealing sheet 11, which covers the injection port 102. The inner cover 2 is located in the cavity of the outer cover 101; the top center of the inner cover 2 is provided with a protrusion 21, and the protrusion 21 is provided with a first puncture area that can be punctured at the position corresponding to the injection port 102; the top of the inner cover is provided with a flushing port 201 next to the protrusion 21, and a sealing pull ring 22 is provided at the flushing port 201, and the sealing pull ring 22 surrounds the outside of the protrusion 21.

[0024] This utility model discloses a multifunctional bottle cap. By removing the sealing sheet from the outer cap, the injection port is exposed for injection purposes. The flushing port and sealing ring of the inner cap are both located on the outside of the raised portion. This design avoids interfering with the insertion of the injection device and reduces the diameter of the flushing port, increasing the flushing force of the water flow. Furthermore, the raised portion of the inner cap effectively reduces the space inside the cap, increasing the volume of the container that fits with the multifunctional bottle cap.

[0025] The injection port 102 is located at the top center of the outer cover, and the corresponding first puncture area is also located at the center of the protrusion 21.

[0026] The sealing sheet 11 is sealed to the injection port to prevent liquid leakage during production and transportation. To facilitate removal of the sealing sheet from the outer cover during use, the outer cover 1 also includes an operating part 12 connected to the sealing sheet 11. This operating part 12 allows the sealing sheet 11 to be removed from the injection port by applying force to the operating part 12, exposing the injection port 101. Specifically, when pulled by the operating part, the sealing sheet 11 can be pulled off the top of the outer cover to expose the injection port. The operating part 12 and the sealing sheet 11 are fixedly connected. Preferably, the operating part and the sealing sheet are integrally formed, and the thickness at the connection point is greater than the thickness of the sealing sheet to ensure that the operating part and the sealing sheet can be removed from the outer cover together.

[0027] For example, the operating part 12 can be configured in the shape of a pull ring. In this case, the operating part is located on the top of the outer cover 1. The pull ring-shaped operating part is suitable for the outer cover 1 with a larger area, so that a person can pull the pull ring to separate the sealing sheet from the outer cover and expose the injection port. The operating part 12 can also be configured in a folding shape, which is suitable for the outer cover 1 with a smaller area. The connection between the outer cover and the sealing sheet can be provided with a thinning part (the thickness of the thinning part is significantly smaller than the thickness of the outer cover and the sealing sheet) or a modified part (the hardness and strength of the modified part are significantly lower than the hardness and strength of the outer cover and the sealing sheet). After a person bends the thinning part or the modified part, it breaks, thereby separating the sealing sheet from the outer cover and exposing the infusion port. In this case, the operating part is not required to separate the sealing sheet from the outer cover.

[0028] The sealing sheet can be integrally formed with the outer cover, or it can be attached to the top plate of the outer cover.

[0029] According to a preferred embodiment of this invention, the outer cover 1 includes an upper cover 13, a connecting pull ring 14, and a lower ring cover 15 connected sequentially from top to bottom. The upper cover 13, the connecting pull ring 14, and the lower ring cover 15 together define the outer cover cavity, and the opening of the outer cover cavity is located at the bottom of the lower ring cover 15. The injection port 101, the sealing sheet 11, and the operating part 12 are located at the top of the upper cover 13.

[0030] The connecting pull ring 14 is configured to separate from the upper cover 13 and lower ring cover 14 by applying force, so that the part of the inner cover with a rinsing port can be exposed after the upper cover is removed. When the rinsing port on the inner cover needs to be used, the connecting pull ring 14 is pulled to separate it from the upper cover 13 and lower ring cover 15, and then the upper cover 13 is removed. After pulling open the sealing pull ring, the rinsing port 201 is exposed. Preferably, the connecting pull ring 14 is connected to the upper cover 13 and lower ring cover 15 by an easy-tear structure. The easy-tear structure can be achieved by setting a thinning part (the thickness of the thinning part is significantly less than the thickness of the upper cover, lower ring cover and connecting pull ring) or a modified part (the hardness and strength of the modified part are significantly lower than the hardness and strength of the upper cover, lower ring cover and connecting pull ring), etc. The easy-tear structure is existing technology, especially common in beverage bottle caps, and will not be described in detail here.

[0031] To facilitate applying force to the connecting pull ring, the connecting pull ring 14 is provided with a handle 141 protruding from the side wall of the outer cover 1. The cross-sectional shape of the handle 141 is "L" shaped, with the vertical side of the handle parallel to the side wall of the outer cover and the horizontal side perpendicularly connected to the outer wall of the connecting pull ring 14.

[0032] To facilitate connection with different external rinsing heads during rinsing, the lower ring cap 15 is provided with an outer ring groove 151 to enhance the application scenarios of the multi-functional bottle cap, that is, after removing the upper cap 13, other rinsing devices can be connected through the outer ring groove 151.

[0033] It should be noted that the length of the upper cover 13 (the length being the distance from the top to the bottom) is at least increased to cover the protruding portion 21 and the flushing port 201 of the inner cover, that is, the protruding portion 21, the flushing port 201, and the sealing pull tab 22 of the inner cover are located in the space area defined by the upper cover 13 for position limitation. The connecting pull ring 14 and the lower ring cover 15 are located below the flushing port of the inner cover. To improve the stability of the inner cover 2 after the upper cover 13 is removed, the lower ring cover 15 can cover at least 1 / 2 of the length of the inner cover 2 and covers the lower part of the side wall of the inner cover 2, that is, the lower ring cover 15 extends upward from the bottom of the side wall of the inner cover 2 to cover at least 1 / 2 of the length of the inner cover 2. Preferably, the covering length of the lower ring cover 15 to the inner cover 2 does not exceed 2 / 3 of the length of the inner cover 2.

[0034] For the convenience of assembly, the inner cover 2 and the outer cover 1 are connected by a snap-fit manner, which enhances the convenience and yield of the multi-functional bottle cap assembly process. Specifically, the inner cover 2 is respectively connected with the upper cover 13 and the lower ring cover 15 through snap-fit structures. In this embodiment, the inner side wall of the upper cover 13 is provided with a first clamping groove 131, the outer side wall of the inner cover 2 is provided with a first clamping protrusion 23 that matches the first clamping groove 131, the first clamping groove 131 and the first clamping protrusion 23 are located below the flushing port 201, the first clamping groove 131 is located at the lower part of the inner side wall of the upper cover, and the first clamping protrusion 23 is located at the upper part of the outer side wall of the inner cover 2. The inner side wall of the lower ring cover 15 is provided with a second clamping groove 152, the outer side wall of the inner cover 2 is provided with a second clamping protrusion 24 that matches the second clamping groove 152, the second clamping groove 152 is located at the lower part of the inner side wall of the lower ring cover 15, and the second clamping protrusion 24 is located at the lower part of the outer side wall of the inner cover 2. Preferably, the clamping grooves (i.e., the first clamping groove and the second clamping groove) are annular grooves, and the clamping protrusions (i.e., the first clamping protrusion and the second clamping protrusion) are annular protrusions. In practical applications, the positions of the clamping grooves and the clamping protrusions can also be interchanged, which is not limited to the manner in this embodiment.

[0035] The inner cover 2 is provided with an inner cover cavity 202 that opens downward, and the shape of the inner cover cavity 202 is a "convex" shape, that is, the protruding portion 21 is formed by the outer wall of the inner cover protruding as a whole, rather than a solid protruding portion. Such arrangement can effectively reduce the space inside the cap body and increase the volume of the container matched with the multi-functional bottle cap.

[0036] The sealing pull ring 22 includes a sealing portion 221 and a pull ring portion 222 connected together. The sealing portion 221 covers the flushing port 201, and the pull ring portion 222 surrounds the outside of the protrusion 21. On the one hand, this avoids affecting the puncture of the injection device; on the other hand, it facilitates applying force to the pull ring portion. The pull ring portion 222 is configured such that applying force to it can remove the sealing portion from the flushing port, exposing the flushing port. That is, when pulled by the pull ring portion, the sealing portion can be pulled off from the top of the inner cover to expose the flushing port. Preferably, the pull ring portion and the sealing portion are integrally formed.

[0037] The sealing part 221 is sealed to the perimeter of the rinsing port to prevent liquid leakage from the rinsing port during production and transportation. To facilitate removal of the sealing part from the inner cover, a thinning part (the thickness of the thinning part is significantly less than the thickness of the inner cover and the sealing part) or a modified part (the hardness and strength of the modified part are significantly lower than the hardness and strength of the inner cover and the sealing part) can be provided at the connection between the inner cover and the sealing part, so that the sealing part can be more easily removed from the inner cover.

[0038] Preferably, the pull ring portion 222 is annular in shape and surrounds the outside of the protrusion. The diameter of the pull ring portion 222 is larger than the diameter of the protrusion but smaller than the diameter of the inner cover.

[0039] To improve the transport stability and sealing of the multifunctional bottle cap, the multifunctional bottle cap also includes a rubber stopper 3 and a support cap 4 located between the outer cap and the inner cap. That is, the rubber stopper 3 and the support cap 4 are located inside the outer cap cavity 101 and fill the gap between the outer cap and the inner cap.

[0040] The rubber stopper 3, the support cap 4, and the injection port 101 are respectively provided with a second puncture area and a third puncture area to facilitate the puncture of the injection puncture device. When in use, after the injection port is exposed, the injection puncture device passes through the second puncture area, the third puncture area, and the first puncture area in sequence to obtain the liquid in the container.

[0041] Preferably, the rubber stopper 3 is installed between the outer cover and the support cover 4 by snap-fit. Specifically, the rubber stopper 3 has an assembly protrusion ring 31 on its outer side, a first assembly groove 32 on the upper surface of the rubber stopper 3 near the assembly protrusion ring 31, and a second assembly groove 33 on the lower surface of the rubber stopper 3 near the assembly protrusion ring 31.

[0042] The top wall of the outer cover cavity of the outer cover 3 is provided with an upper cover groove 132 that is adapted to the mounting protrusion 31, and the top wall of the outer cover cavity is provided with an upper cover protrusion 133 that cooperates with the first mounting groove 32. That is, the mounting protrusion 31 can be embedded in the upper cover groove 132, and at the same time, the upper end of the upper cover protrusion 133 is embedded in the first mounting groove 32, thus completing the snap-fit ​​between the rubber plug and the outer cover.

[0043] The top of the support cover 4 is provided with a support protrusion 41 that matches the second assembly groove 33, and the outer side of the support protrusion 41 is provided with a support platform 42 that matches the assembly convex ring 31, that is, the support protrusion 41 can be embedded into the second assembly groove 33, while the lower end of the assembly convex ring is located on the support platform 42.

[0044] Preferably, the positions of the first assembly groove 32 and the second assembly groove 33 correspond to each other. In this embodiment, the cross-sectional shape of the rubber plug 3 is similar to an "I" shape. The rubber plug 3 is made of a flexible colloidal material, such as silica gel.

[0045] It should be noted that the upper cover protrusion is arranged around the outer side of the injection port, and the upper cover groove is arranged around the outer side of the upper cover protrusion. The first assembly groove and the second assembly groove are arranged around the outer side of the second piercing area, and the assembly convex ring is arranged around the outer side of the first assembly groove and the second assembly groove. The support protrusion is arranged around the outer side of the third piercing area, and the support platform is arranged around the outer side of the support protrusion.

[0046] The support cover 4 is provided with a downwardly open support cavity 401, and the protrusion portion 21, the sealing pull ring 22 and the flushing port 201 are located in the support cavity 401, that is, the support cover 4 covers the top of the inner cover 2, so as to serve the purpose of protecting the protrusion portion, the sealing pull ring and the flushing port.

[0047] The bottom of the support cover 4 abuts against the top of the inner cover, and the support cover 4 is snap-connected with the outer cover. Specifically, the outer side wall of the support cover 4 is provided with a third clamping protrusion 43, and the inner side wall of the outer cover is provided with a third clamping slot (not shown in the drawings) that matches the third clamping protrusion 43. The third clamping slot is located on the inner wall of the upper cover and above the first clamping slot 131. The third clamping protrusion 43 is located at the lower part of the side wall of the support cover 4, lower than the positions of the flushing port and the sealing pull ring, so as to better protect the protrusion portion, the sealing pull ring and the flushing port.
