[0028] Example

[0029] Please see Figure 1 This embodiment provides a small-capacity storage cover 100, which includes an upper cover 110, a cutter 120, and a lower cover 130.

[0030] Please see Figure 2 and Figure 3 The upper cover 110 contains a guide ring 111, which is an annular structure. Its top end connects to the top of the upper cover 110, and its lower end extends along the axial direction of the upper cover 110. The height of the guide ring 111 is less than the height of the upper cover 110. In this embodiment, the outer wall of the guide ring 111 is provided with multiple first guide posts 112. The first guide posts 112 are vertically arranged along the axial direction of the upper cover 110. The placement of the first guide posts 112 on the outer wall of the guide ring 111 reduces the possibility of powder entering the gap between the first guide posts 112. The inner wall of the upper cover 110 is provided with an internal thread 113. The gap between the inner wall of the upper cover 110 and the guide ring 111 forms a space for the cutter 120 and the lower cover 130 to be inserted. The first guide posts 112 are used to cooperate with the cutter 120, and the internal thread 113 is used to cooperate with the lower cover 130.

[0031] Please see Figure 4The cutter 120 includes a vertical drive section 121 located at the upper part of the cutter 120 and a threaded drive section 122 located at the lower part of the cutter 120. The inner wall of the vertical drive section 121 is provided with a plurality of second guide posts 123, the outer wall of the threaded drive section 122 is provided with drive threads 124, and the bottom of the threaded drive section 122 is provided with cutting teeth 125. In this embodiment, by respectively setting the vertical drive section 121 and the threaded drive section 122 at the upper part of the inner wall and the lower part of the outer wall of the cutter 120, the second guide posts 123 on the vertical drive section 121 and the drive threads 124 on the threaded drive section 122 do not interfere with each other. The positions of the second guide posts 123 and the drive threads 124 can partially overlap or be spaced apart. When the second guide posts 123 and the drive threads 124 partially overlap, the overall height of the cutter 120 can be reduced. When it is necessary to increase the height of the cutter 120, the second guide posts 123 and the drive threads 124 can be spaced apart.

[0032] Specifically, the cutter 120 has a height of 18-26 mm, the vertical drive section 121 has a height of 6-8 mm, and the threaded drive section 122 has a height of 12-14 mm. The second guide post 123 can be located along the entire length of the vertical drive section 121 or only in the upper part of the vertical drive section 121. The drive thread 124 can be located along the entire length of the threaded drive section 122 or only in the upper part of the vertical drive section 121. To minimize the height of the cutter 120, in this embodiment, it is preferable that the second guide post 123 is located along the entire length of the vertical drive section 121 and the drive thread 124 is located along the entire length of the threaded drive section 122. In this case, better guiding effect and a smaller cutter 120 size can be ensured.

[0033] The vertical drive section 121 is embedded outside the guide ring 111, and each second guide post 123 is inserted between adjacent first guide posts 112. The number of first guide posts 112 and second guide posts 123 is in a multiple relationship, with either the first guide post 112 or the second guide post 123 having 6-8 posts, and the other having 2-4 times the number of the former. By setting the first guide posts 112 and the second guide posts 123 in a multiple relationship, it is possible to quickly embed multiple first guide posts 112 and multiple second guide posts 123 at any angle, making the operation simpler.

[0034] The bottom of the threaded drive section 122 has an inwardly inclined end face 126, which is connected to the cutting teeth 125. The cutting teeth 125 occupy 1 / 4 to 1 / 2 of the bottom of the threaded drive section 122. By setting the inwardly inclined end face 126, the sealing film 135 cut by the cutting teeth 125 can be lifted up, preventing the sealing film 135 from entering the bottle.

[0035] In some alternative implementations, please refer to Figure 5 The drive thread 124 is provided with at least two intervals 127. The width of each interval 127 is less than the length of each segment of the drive thread 124. Therefore, in this embodiment, while maintaining a good driving effect of the drive thread 124, the thread contact area can be reduced, decreasing the complexity of the injection mold or the amount of material used during production, thus achieving a lightweight cutter 120. Furthermore, the broken thread also serves to prevent detachment. The broken thread forms a physical obstacle; when the cutter 120 (or the cover) is rotated in the opposite direction in an attempt to disassemble it, the broken portion of the thread will jam the corresponding structure, preventing complete unscrewing and avoiding easy removal of the cover. The broken thread will "slip" when tightened to a certain position, limiting the maximum torque and preventing deformation of the plastic thread or breakage of the cover due to over-tightening.

[0036] In some alternative implementations, please refer to Figure 5 The drive thread 124 is provided with multiple quadrilateral guide ports 128. The quadrilateral guide ports 128 are located in the middle and lower part of the drive thread 124. The quadrilateral guide ports 128 facilitate the entry and exit of sterilization water, enabling the sterilization operation of the cutter 120.

[0037] Furthermore, in this embodiment, the cutter 120 is also provided with a transverse straight segment 129. The height of the transverse straight segment 129 is 1-2mm. The transverse straight segment 129 is located on the upper part of the thread of the drive thread 124, and the outer diameter of the transverse straight segment 129 is smaller than the thread crest diameter of the cutter 120. The transverse straight segment 129 can limit the drive thread 124 and prevent the cutter 120 from continuously moving along the drive thread 124 during rotation.

[0038] Please see Figure 6The lower cover 130 includes an upper section 131 and a lower section 132. The outer wall of the upper section 131 is provided with an external thread 133, and the bottom of the upper section 131 is provided with an internal thread 134 and a sealing film 135 for sealing the end of the upper section 131. The upper part of the lower cover 130 is inserted between the inner wall of the upper cover 110 and the cutter 120, and the external thread 133 of the lower cover is threadedly connected to the internal thread 113 of the upper cover. The drive thread 124 is threadedly connected to the internal thread 134 of the lower cover. The cutting teeth 125 are close to the sealing film 135 and cut the sealing film 135 when the upper cover 110 is rotated.

[0039] In this embodiment, the sealing film 135 is disposed at the end of the upper section 131 of the lower cover, and it can be cut during the movement of the cutter 120. At this time, the material inside the sealing film 135 can leak out into the bottle through the cut opening.

[0040] In this embodiment, a filling cavity is formed between the guide ring 111, the cutter 120, and the sealing film 135. The volume of the filling cavity is adjusted by regulating the outer diameters of the guide ring 111, the vertical drive section 121, and the threaded drive section 122. The outer diameter of the guide ring 111 is 18-22 mm; the outer diameter of the vertical drive section 121 is 19-23 mm; and the outer diameter of the threaded drive section 122 is 20-24 mm. In the actual production of the storage lid, the outer diameters of the guide ring 111, the vertical drive section 121, and the threaded drive section 122 can be adjusted according to the actual storage conditions of this model of storage lid, thereby adjusting the volume of the filling cavity within a certain range.

[0041] The working principle of the small-capacity storage cap 100 provided in this embodiment is as follows: This embodiment utilizes the cooperation between the upper cap 110, the cutter 120 and the lower cap 130 to cut the sealing film 135 on the lower cap 130. The upper cap 110 rotates, and the first guide post 112 drives the second guide post 123 of the vertical drive section 121 on the cutter 120 to move downward as a whole. At the same time, the drive thread 124 on the cutter 120 cooperates with the inner thread 134 on the lower cap 130 to achieve rotational cutting, and finally cuts the sealing film 135 at the bottom of the lower cap 130 to allow the contents to enter the bottle.

[0042] Furthermore, this utility model also provides a storage bottle, which includes a bottle body and the aforementioned small-capacity storage cap 100, with the lower cap 130 of the small-capacity storage cap 100 connected to the bottle body. In this embodiment, the bottle body can have its own cap. In this case, the lower section of the lower cap 130 of the small-capacity storage cap 100 can be configured to connect and install with the cap of the bottle body using a convex ridge snap-fit ​​method. This design ensures that the lower cap 130 is easier to sterilize and more convenient to operate. In some other embodiments, an internal thread that mates with the external thread of the bottle mouth can also be directly provided on the lower section of the lower cap 130 to achieve a threaded connection between the lower cap 130 and the bottle body.

[0043] In summary, the small-capacity storage cap 100 and storage bottle provided by this utility model, by respectively setting the vertical drive section 121 and the threaded drive section 122 on the inner and outer sides of the cutter 120, where the vertical drive section 121 and the threaded drive section 122 do not interfere with each other, helps to reduce the length of the cutter 120, thereby achieving a small storage space and reducing the overall volume, making it suitable for tea powder. Meanwhile, the lower section of the lower cap 130 is not threaded, but directly connected to the bottle body by a snap-fit ​​method. This design helps to reduce sterilization dead zones and facilitates sterilization. Furthermore, the quadrilateral guide port 128 on the cutter 120 also facilitates the entry of sterilizing water, which helps to improve the sterilization effect.

[0044] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
