[0039] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is intended to help understand the present invention, but does not constitute a limitation of the present invention.

[0040] In this article, "inside" and "outside" are defined with reference to the longitudinal center axis of the bottle cap or packaging bottle, and the direction closer to the longitudinal center axis is considered inside, and the opposite is considered outside.

[0041] Figures 1 to 11 The figures are drawn in true proportion. To keep the description concise, the proportions of each component are not listed one by one. However, the proportions and positions of each component should be considered as part of the content of this description. Example 1

[0042] Reference Figures 1 to 8 The embodiment provides a storage bottle cap 100, which can independently store liquid or solid substances, such as tea, honey, fruit juice concentrate, etc. The embodiment also relates to a packaging bottle, which includes a bottle 200 and the above-mentioned storage bottle cap 100. The bottle 200 has a bottle mouth 201, and the storage bottle cap 100 is arranged on the bottle mouth 201. When the storage bottle cap 100 is in the initial closed state, the substance in the storage bottle cap 100 can be stored independently and separated from the liquid (such as water) in the bottle 200. Figure 5 When the storage bottle cap 100 is in the open state, the substance in the storage bottle cap 100 can flow out, for example, into the bottle 200 below and mix with the liquid in the bottle 200, as shown. Figure 6 and Figure 7 The storage bottle cap 100 also has a drinking state, in which the object in the storage bottle cap 100 and the liquid in the bottle 200 have been mixed, for example, to become tea, and the storage bottle cap 100 is converted into a state in which the drinking port is exposed, as shown. Figure 8 shown.

[0043] Combine Figure 1 and Figure 2 The storage bottle cover 100 includes an upper cover 1, a lower cover 2, a movable column 3 and a storage bin 4. The storage bin 4 is configured to be inserted into the bottle mouth 201 of the bottle 200 and has a storage cavity 40 for accommodating substances. The storage cavity 40 contains liquid or solid substances, such as tea leaves. Figure 2 and Figure 5As shown, the upper end of the storage bin 4 is open and has an outwardly extending flange 41. The lower cover 2 is configured to be connected to the bottle mouth 201 of the bottle 200 and press the flange 41 against the bottle mouth 201. The upper cover 1 is rotatably connected to the lower cover 2 and can be detached from the lower cover 2. The lower portion of the movable column 3 is movably inserted into the storage cavity 40, and the upper portion of the upper cover 1 and the movable column 3 are interlocked and configured to drive the movable column 3 to rotate. The upper portion of the movable column 3 is inserted into the lower cover 2 and is threadedly connected so that when the movable column 3 rotates, it moves downward to open the storage cavity 40.

[0044] The lower cover 2 is transparent and made of a transparent plastic. In a preferred embodiment, the lower cover 2 is made of polypropylene (PP), and the storage compartment 4 is made of high-density polyethylene (HDPE). Furthermore, the upper and / or lower surfaces of the flange 41 of the storage compartment 4 may include a thermoplastic elastomer (TPE) layer, formed by two-color injection molding. This structure, in which the flange 41 is compressed after the lower cover 2 is screwed onto the bottle mouth 201, ensures a seal between the bottle mouth 201 and the storage bottle cap 100 without relying on the inherent elasticity of the lower cover 2. This allows the lower cover 2 to be made of a relatively poorly sealed transparent material, such as polypropylene. The PP lower cover 2 is transparent and has a high gloss, offering excellent aesthetics. Once attached to the bottle 200, it does not disrupt the overall transparency of the bottle 200, thus achieving both good sealing and aesthetics. Furthermore, the flange 41 is a horizontally arranged ring, the lower cover 2 has a horizontal and downwardly facing step surface 21, and the flange 41 is configured to be pressed between the step surface 21 and the upper end surface of the bottle mouth 201, as shown in FIG. Figure 5 and Figure 6 shown.

[0045] The structures of the above four components are described in detail below.

[0046] The material of the upper cover 1 includes HDPE, which gives the upper cover 1 good sealing performance and makes a good seal between the upper cover 1 and the lower cover 2. At the same time, since the exposed part of the upper cover 1 is relatively small, the opaque upper cover 1 has little effect on the aesthetics of the packaging bottle itself. The upper cover 1 is an integral injection molded part. The upper cover 1 can seal the upper end of the lower cover 2. Figure 5 and Figure 6 As shown, the upper cover 1 includes an outer connecting edge 11 extending downward from the top and a sealing skirt 12. The outer connecting edge 11 is threadedly attached to the upper portion of the lower cover 2. The sealing skirt 12 is located inside the outer connecting edge 11, with a gap between the two. The upper portion of the lower cover 2 is inserted into the gap, with the sealing skirt 12 abutting against the inner surface of the lower cover 2. The upper cover 1 also has a connecting skirt 13 extending downward from the top, located inside the sealing skirt 12. This connecting skirt 13 is used to connect to the movable column 3 to drive the movable column 3 to rotate and move up and down.

[0047] The lower cover 2 is hollow and cylindrical, open at both ends. The diameter of the upper portion of the lower cover 2 is smaller than the diameter of the lower portion of the lower cover 2. The upper portion of the lower cover 2 is joined to and sealed by the upper cover 1, while the lower portion of the lower cover 2 is joined to and sealed against the bottle mouth 201 of the bottle 200. Specifically, the upper cover 1 is screwed onto the upper portion of the lower cover 2, and the lower portion of the lower cover 2 is screwed onto the bottle mouth 201 of the bottle 200.

[0048] The movable column 3 comprises an outer cylinder 31, which is hollow and cylindrical with open ends. The upper end of the outer cylinder 31 is inserted into the upper portion of the lower cover 2 and connected by threads. Specifically, the outer cylinder 31 has an external thread 310 on its upper outer surface, while the lower cover 2 has an internal thread 20 on its upper inner surface. These threads 310 and 20 form two interlocking, counter-rotating threads, allowing the outer cylinder 31 to move downward when the lower cover 2 rotates in a set direction.

[0049] The movable column 3 also includes an inner cylinder 32, which is hollow and open at both ends. In the preferred embodiment shown in the accompanying drawings, a filter screen 321 is connected to and covered at the upper end of the inner cylinder 32. This storage bottle cap 100 is suitable for storing cold-brewed tea leaves. If the storage compartment 4 contains solid materials such as tea leaves, the filter screen 321 at the top of the inner cylinder 32 can filter out the solid materials (tea leaves) from the liquid, preventing the tea leaves from flowing into the mouth with the liquid, making it convenient to use.

[0050] The inner cylinder 32 is located in the upper part of the outer cylinder 31 with a gap between the two. The connecting skirt 13 of the upper cover 1 is inserted into the gap and is configured to drive the movable column 3 to rotate. Specifically, in the example shown in the drawings, Figure 3 and Figure 4As shown, a ratchet 131 is provided on the outer surface of the connecting skirt 13, and a pawl 312 is provided on the inner surface of the outer cylinder 31. The pawl 312 cooperates with the ratchet 131 to drive the movable column 3 to rotate when the upper cover 1 rotates in a first direction, and to cause the upper cover 1 and the movable column 3 to slip against each other when the upper cover 1 rotates in a second direction; the second direction is opposite to the first direction. There can be multiple pawls 312. When the upper cover 1 rotates in the first direction (counterclockwise), the pawl 312 abuts against the first tooth flank of the ratchet 131 teeth; when the upper cover 1 rotates in the second direction (clockwise), the pawl 312 abuts against the second tooth flank of the ratchet 131 teeth. The inclination angle of the first tooth flank relative to the tangent to the ratchet 131 is greater than the inclination angle of the second tooth flank relative to the tangent to the ratchet 131. When the pawl 312 abuts the first tooth surface, it can be pushed and rotated by the ratchet 131. However, when the pawl 312 abuts the second tooth surface, the friction between the two is small, and the pawl 312 slides across the second tooth surface, causing the outer cylinder 31 to slip relative to the connecting skirt 13. Rotation of the upper cover 1 does not drive the movable column 3. In other examples, the configuration may be such that a ratchet is provided on the outer surface of the inner cylinder 32, and a pawl is provided on the inner surface of the connecting skirt 13.

[0051] The lower end of the inner tube 32 is connected to the outer tube 31 via an inclined folded edge 33. This folded edge 33 defines through-holes 331 for liquid flow. When the bottle 200 is low on liquid, these through-holes 331 can be used to pour out the entire contents. Multiple through-holes 331 are spaced along the circumference of the storage bottle cap 100. The movable column 3 is made of polypropylene and is a single, integral injection-molded component.

[0052] The storage bin 4 is a hollow cylindrical body with an open top. In the example shown in the drawings, the bottom of the storage bin 4 is closed. The storage bin 4 is a component made of HDPE injection molding. The bottom of the storage bin 4 includes a puncture portion 42, which is surrounded by an annular thin rubber portion 43. The thin rubber portion 43 has an annular groove, so that the thickness of the thin rubber portion 43 is reduced and the strength is reduced. Figure 5 As shown, when the storage bottle cap 100 is in the closed state, the lower end of the outer cylinder 31 of the movable column 3 has a sharp cutter portion 311, and the cutter portion 311 is located just above the thin adhesive portion 43. When the storage bottle cap 100 is in the open state, the movable column 3 moves downward, and the cutter portion 311 pierces the thin adhesive portion 43. Figure 8As shown, when the storage bottle cap 100 is in the drinking state, the upper cover 1 is separated from the lower cover 2, and the lower end of the movable post 3 is open to allow the liquid in the bottle 200 to flow out. In other examples, the bottom of the storage compartment 4 is open and sealed by a sealing membrane that can be pierced by the cutter portion 311. In other embodiments, the bottom of the movable post 3 is sealed and plugged, while the bottom of the storage compartment 4 is open and plugged by the movable post 3. When the movable post 3 moves downward, a gap is formed between the movable post 3 and the storage compartment 4, allowing the storage cavity 40 to be opened.

[0053] Furthermore, the puncture portion 42 is circular, and the ratio of the diameter of the puncture portion 42 to the inner diameter of the bottle mouth 201 is (8.0-9.9):10. The large diameter of the puncture portion 42 not only allows for liquid filling, but also ensures smooth descent of solid particles, especially tea leaves.

[0054] The movable column 3 has an outwardly protruding retaining rib 313 on the central outer surface of the outer cylinder 31. The lower cover 2 has a downwardly facing upper limit surface 22, and the storage compartment 4 has an upwardly facing lower limit surface 44. The retaining rib 313 is confined between the upper and lower limit surfaces 22 and 44. When the upper cover 1 is unscrewed to drink the liquid in the bottle 200, the movable column 3 will not fall out even if the bottle 200 is tilted or even turned upside down.

[0055] The storage bin 4 of the storage bottle cap 100 is located in the bottle mouth 201. When the storage bottle cap 100 is in the drinking state, the lower cover 2, the storage bin 4 and the movable column 3 are maintained on the bottle mouth 201, and the upper cover 1 is separated from the lower cover 2 to expose the drinking mouth at the top of the lower cover 2.

[0056] The use process of the storage bottle cap 100 of the embodiment is as follows:

[0057] 1. Filling: Screw the movable column 3 into the lower cover 2, and screw the upper cover 1 onto the lower cover 2. The ratchet 131 on the upper cover 1 will slip when it is turned clockwise. Finally, tighten the upper cover 1 and the lower cover 2, and seal the top of the lower cover 2 to achieve a seal between the upper cover 1 and the lower cover 2. At this time, these three parts form a cup-shaped container. Put tea leaves or other solids into the container from the lower end of the outer cylinder 31 of the movable column 3, and finally buckle the storage bin 4. Figure 5 As shown, the lower cover 2 has a downwardly extending flange, over which the open end of the storage compartment 4 fits with an interference fit. When the storage bottle cap 100 is assembled onto the bottle 200, the storage compartment 4 extends into the bottle opening 201, with its flange 41 hooked onto the bottle opening 201. The lower cover 2 is then screwed onto the bottle opening 201 until the stepped surface of the lower cover 2 presses the flange 41 against the bottle opening 201, sealing the storage bottle cap 100 and the bottle opening 201.

[0058] 2. Adjustment: Rotate the upper cover 1 in the first direction (counterclockwise), and the movable column 3 is driven to rotate under the action of the ratchet 131. Due to the action of the thread, the upper cover 1 and the movable column 3 move in opposite directions (such as Figure 6 As shown), the movable column 3 moves downward, the cutter portion 311 on the movable column 3 punctures the thin adhesive portion 43 at the bottom of the storage bin 4, and further supports the puncture portion 42, and the material in the storage bin 4 moves along the Figure 7 The liquid flows downward into the bottle 200 in the direction indicated by the middle arrow; screw the upper cover 1 back onto the lower cover 2, and shake the bottle 200 to mix the contents of the bottle 200. Figure 7 shown.

[0059] 3. Drinking: Unscrew the upper cover 1 to expose the drinking port on the top of the lower cover 2. The liquid in the bottle 200 flows out along the Figure 8 Among them, a small amount of liquid near the edge corner of the bottle 200 can flow out through the through hole 331 on the side of the storage bottle cap 100, avoiding the problem of liquid in the bottle 200 being unable to flow out when the amount of liquid is small, thereby solving the problem of residual liquid in the bottle 200.

[0060] The storage bottle cap 100 and packaging bottle of the embodiment have a separate lower cover 2 and a storage bin 4. The lower cover 2 is connected to the bottle mouth 201 of the bottle 200, and the storage bin 4 is inserted into the bottle mouth 201 for storing substances (such as honey, tea, etc.). The flange 41 of the storage bin 4 is used to achieve a seal between the bottle cap and the bottle mouth 201, thereby allowing the lower cover 2 to be made of a transparent material (such as polypropylene). The lower cover 2 is set to be transparent while ensuring good sealing performance with the bottle mouth 201, taking into account both aesthetics and sealing. Through holes 331 are provided on the flange 33 of the movable column 3, through which all liquid in the bottle 200 can flow out. If the substance stored in the storage bin 4 is a solid such as tea, a filter 321 is provided at the top of the inner cylinder 32 of the movable column 3 to filter out the solid substance (tea) in the liquid, making it easy to use and providing a better user experience. Example 2

[0061] Reference Figures 9 to 11 As shown, the storage bottle cap of this embodiment differs from that of embodiment 1 only in that: the storage bottle cap 100 is suitable for holding liquids, no filter is provided at the top of the inner cylinder 32 of the movable column 3, and the top of the inner cylinder 32 is open and not blocked; the rest is basically the same as embodiment 1.

[0062] During filling, first screw the movable column 3 into the lower cover 2, buckle the storage bin 4 to form a container with an open top, pour liquid from the upper end of the inner cylinder 32 of the movable column 3, and finally tighten the upper cover 1.
