Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bottles, in particular to an anti-loss bottle cap and a bottle. Background Art
[0002] As an important component of a bottle, the bottle cap not only needs to ensure the sealing of the contents, but also be easy for the user to open and close during use. With the improvement of living standards, people have also put forward higher requirements for the convenience of use and functional diversity of bottle caps.
[0003] At present, in order to improve the anti-loss performance of bottle caps and facilitate opening, the existing technical means on the market generally include but are not limited to the following: First, the bottle cap is fixed to the bottle body by adding a connecting belt, but this connecting belt is easily damaged during repeated use; second, the bottle cap and the bottle body are designed to have a snap-fit structure. Although this method can prevent the bottle cap from being lost, it requires a lot of force when opening, which is inconvenient for users with less hand strength (such as children or the elderly). However, these technical means are generally not convenient enough in actual use. Specifically, the existing connection methods are either easily damaged after long-term use, or are not convenient to open during use, especially when frequent opening and closing are required, resulting in a poor user experience. These problems directly affect the user's convenience. Utility Model Content
[0004] In order to improve the problem of easy loss of bottle caps and improve the convenience of use, the present application provides an anti-loss bottle cap and a bottle.
[0005] In the first aspect, the present application provides an anti-loss bottle cap, which adopts the following technical solutions:
[0006] A loss-proof bottle cap comprises an inner cap and an outer cap, the inner cap being used to connect with the bottle body, the inner cap being sleeved inside the outer cap, the inner cap comprising a pointed mouth portion and a connecting portion, the outer cap being formed with a receiving cavity for receiving the pointed mouth portion, the cross-sectional diameter of the receiving cavity gradually becoming smaller, an opening being provided at the top of the receiving cavity, a discharge port being provided at the upper end of the pointed mouth portion, a sealing block being provided at the top end of the pointed mouth portion, the outer cap being rotated so as to rotate the outer cap relative to the inner cap to adjust the position of the sealing block in the receiving cavity, and when the sealing block moves toward the opening, the gap between the sealing block and the inner wall of the receiving cavity becomes smaller, until the sealing block is pressed against the inner wall of the receiving cavity, and the farther the sealing block is from the opening, the larger the gap between the sealing block and the inner wall of the receiving cavity.
[0007] By adopting the above-mentioned device, the outer cover and the inner cover are sleeved together, ensuring that the outer cover is not easily lost during use. The user can adjust the discharge state of the bottle cap by rotating the outer cover, that is, controlling the size of the gap between the sealing block and the inner wall of the accommodating chamber, thereby achieving fine control over the outflow of fluid substances such as glue, and the operation is simple. When in use, rotating the outer cover until the sealing block is against the inner wall of the accommodating chamber can achieve a good sealing effect and reduce the leakage of substances such as glue in the bottle. Rotating the outer cover in the opposite direction allows a certain gap to be left between the sealing block and the inner wall of the accommodating chamber, which facilitates the outflow of substances in the bottle, effectively improving the practicality of the bottle cap and the convenience of operation. The anti-loss bottle cap of the present application does not require the outer cover to be completely unscrewed. It only needs to rotate the outer cover to a certain angle to allow the substances in the bottle to flow out, which can reduce the probability of the outer cover being lost and improve the convenience of use.
[0008] Preferably, the cross sections of the sealing block and the opening are both circular, and the diameter of the sealing block is larger than the diameter of the opening.
[0009] By adopting the above device, when glue is not used, the sealing block presses against the inner wall of the accommodating cavity, reducing the probability of the substance in the bottle flowing out of the opening, and achieving a good sealing effect.
[0010] Preferably, an annular groove is formed between the pointed mouth and the connecting portion, a limiting plate is provided on the outer wall of the pointed mouth, a matching portion is provided at the bottom of the accommodating cavity, and the matching portion is embedded in the annular groove. When the outer cover rotates, the matching portion and the limiting plate form abutment.
[0011] By adopting the above-mentioned device, the limiting piece abuts against the matching part, which can provide physical restrictions when the outer cover is rotated to a certain position, preventing the outer cover from over-rotating, ensuring the precise positioning of the sealing block in the accommodating cavity, and enabling the tool to more accurately control the size of the gap between the sealing block and the inner wall of the accommodating cavity, thereby achieving precise control of the amount of fluid material flowing out of the bottle.
[0012] Preferably, the cross section of the matching portion is semicircular.
[0013] By adopting the above device, the semicircular matching portion can be easily embedded in the annular groove. When in use, the outer cover is rotated so that the matching portion abuts against the limiting piece, ensuring that the sealing block can be stably moved to the required position.
[0014] Preferably, the connecting portion includes a first internal thread and a first external thread, the bottom of the outer cover is provided with a second internal thread, and the first external thread and the second internal thread form a threaded connection.
[0015] By adopting the above device, the threaded connection design makes the assembly and disassembly process of the inner cover and the outer cover easier, and the user can easily connect or separate the inner cover and the outer cover through a rotating action.
[0016] Preferably, the pointed mouth portion, the connecting portion, the limiting piece and the sealing block are integrally formed.
[0017] By adopting the above device, the one-piece molded parts reduce potential weaknesses in the joints, improve the durability and reliability of the bottle cap, and extend the service life of the product.
[0018] Preferably, the outer ring of the bottom of the outer cover is provided with anti-slip grooves.
[0019] By adopting the above device, the anti-slip pattern provides a better gripping surface, making the user feel more comfortable when picking up or rotating the bottle cap, and reducing the possibility of hand slipping.
[0020] In a second aspect, the present application provides a bottle comprising a bottle body and an anti-loss bottle cap, wherein a first internal thread at the bottom of the inner cap forms a threaded connection with a second external thread at the mouth of the bottle body.
[0021] By adopting the above device, the threaded connection formed by the first internal thread at the bottom of the inner cap and the second external thread at the mouth of the bottle body can ensure a tight fit between the bottle cap and the bottle body, thereby improving the sealing performance of the bottle and reducing the possibility of leakage of the substance in the bottle.
[0022] This application has the following beneficial effects:
[0023] 1. In the present application, the outer cover and the inner cover are sleeved together to ensure that the outer cover is not easily lost during use. The user can adjust the discharging state of the bottle cap by rotating the outer cover, that is, controlling the size of the gap between the sealing block and the inner wall of the accommodating chamber, thereby achieving fine control over the outflow of fluid substances such as glue, and the operation is simple. When in use, rotating the outer cover until the sealing block is pressed against the inner wall of the accommodating chamber can achieve a good sealing effect and reduce the leakage of glue and other substances in the bottle, while rotating the outer cover in the opposite direction so that there is a certain gap between the sealing block and the inner wall of the accommodating chamber, which facilitates the outflow of substances in the bottle, effectively improving the practicality of the bottle cap and the convenience of operation. The anti-loss bottle cap of the present application does not require the outer cover to be completely unscrewed. It only needs to rotate the outer cover to a certain angle to allow the substances in the bottle to flow out, which can reduce the probability of the outer cover being lost and improve the convenience of operation.
[0024] 2. In the present application, the threaded connection formed by the first internal thread at the bottom of the inner cap and the second external thread at the mouth of the bottle body can ensure a tight fit between the bottle cap and the bottle body, thereby improving the sealing performance of the bottle and reducing the possibility of leakage of the substance in the bottle.

DETAILED DESCRIPTION
[0031] The following is combined with Figure 1-4 This application is described in further detail.
[0032] The embodiment of the present application discloses an anti-loss bottle cap.
[0033] like Figure 1-2 As shown, a loss-proof bottle cap includes an outer cover 2 and an inner cover 1. The inner cover 1 is used to connect with the bottle body 3. The inner cover 1 includes a pointed mouth 11 and a connecting portion 12. The pointed mouth 11 is used to control the outflow of fluid substances, and a discharge port 111 is provided at its upper end. A sealing block 112 with a circular cross-section is provided at the top of the pointed mouth 11. The position of the sealing block 112 in the accommodating cavity 21 can be adjusted as needed to control the outflow of the fluid substance. An accommodating cavity 21 for accommodating the pointed mouth 11 is formed on the outer cover 2. The cross-sectional diameter of the accommodating cavity 21 gradually decreases from the bottom to the top, and a circular opening 22 is provided at the top. The diameter of the sealing block 112 is larger than the diameter of the opening 22. When the outer cover 2 rotates, the sealing block 112 can move in the accommodating cavity 21, thereby adjusting the size of the gap between the sealing block 112 and the inner wall of the accommodating cavity 21, thereby achieving control of the outflow of the fluid substance.
[0034] During use, the user can adjust the position of the sealing block 112 by rotating the outer cap 2. When sealing is required, the user rotates the outer cap 2 until the sealing block 112 is close to the opening 22. At this point, the gap between the sealing block 112 and the inner wall of the accommodating chamber 21 is minimized, or even completely sealed, preventing fluid leakage. When the fluid in the bottle is to be used, the user rotates the outer cap 2 in the opposite direction, moving the sealing block 112 away from the opening 22. This increases the gap between the sealing block 112 and the inner wall of the accommodating chamber 21, allowing the fluid to flow out through the discharge port 111.
[0035] like Figure 1-2As shown, in order to ensure that the outer cover 2 can both control the outflow of the fluid in the bottle and prevent the outer cover 2 from falling off the inner cover 1, a semicircular mating portion 23 is provided at the bottom of the accommodating cavity 21 of the outer cover 2, and an annular groove 13 is formed between the pointed mouth portion 11 and the connecting portion 12 of the inner cover 1. During initial assembly, the mating portion 23 is inserted into the annular groove 13, allowing the outer cover 2 to rotate relative to the inner cover 1. In addition, a limit plate 113 is provided on the outer wall of the pointed mouth portion 11. When the outer cover 2 is rotated to a certain angle, the mating portion 23 abuts the limit plate 113, thereby limiting the rotation of the outer cover 2.
[0036] like Figure 1-3 As shown, the connecting portion 12 includes a first internal thread 121 and a first external thread 122. At the same time, the bottom of the outer cover 2 is provided with a second internal thread 24. When the outer cover 2 is connected to the inner cover 1, the first external thread 122 and the second internal thread 24 form a threaded connection, which not only facilitates installation and removal, but also ensures the firmness of the connection between the outer cover 2 and the inner cover 1.
[0037] like Figure 1-2 To enhance the durability and reliability of the bottle cap, the inner cap 1 comprises a one-piece design with its pointed mouth 11, connecting portion 12, retaining piece 113, and sealing block 112. This reduces potential weaknesses at the joints. Furthermore, the outer ring of the bottom of the outer cap 2 is provided with anti-slip grooves 25. These grooves provide a more comfortable grip when the user picks up or rotates the bottle cap, reducing the possibility of slipping.
[0038] The present application also discloses a bottle comprising the above-mentioned anti-loss bottle cap.
[0039] A bottle, such as Figure 1 、 3 As shown in FIG4 , the bottle body 3 and the bottle cap are provided with a second external thread 31 at the top of the bottle body 3. The first internal thread 121 at the bottom of the inner cap 1 is threadedly connected to the second external thread 31 at the top of the bottle body 3. This ensures a secure connection between the bottle cap and the bottle body 3, thereby improving the sealing performance of the bottle and reducing the possibility of leakage of the contents of the bottle.
[0040] Working Principle: By configuring the bottle cap as an outer cap 2 and an inner cap 1, and utilizing the pointed mouth 11 and the discharge port 111 to cooperate with the outer cap 2, the outer cap 2 is rotated to adjust the sealing effect of the bottle cap. The anti-loss bottle cap and bottle of this application, through the sleeve structure of the inner and outer caps 2 and the rotation adjustment mechanism, not only prevents the bottle cap from being lost, but also provides precise control of the outflow of fluid substances.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
