Abstract
Description
Technical Field
[0001] This utility model relates to a long tubular storage lid and packaging bottle. Background Technology
[0002] Storage caps can independently hold solutes (such as honey, concentrated fruit juice, etc.) and can be attached to the bottle neck. When needed, the cap is opened, allowing the solute inside to fall into the bottle and mix. A common type of storage cap includes a screw cap, a storage compartment, and a moving part. The storage compartment has a cavity for holding the substance, the screw cap is screwed onto the top of the storage compartment, and the moving part is movably positioned in the cavity, allowing the bottom of the cavity to be opened to allow the substance in the cavity to flow into the bottle. The storage compartment needs to be threaded to achieve a connection with the screw cap and provide a good seal; the storage compartment also needs to be threaded to the bottle neck to ensure a good seal. To ensure a good seal, storage compartments are mostly made of high-density polyethylene (HDPE), a material known for its sealing properties; however, HDPE itself has poor transparency and is not aesthetically pleasing, affecting the overall appearance of the bottle when attached. In particular, the long tube-type storage cap has a long tubular section that extends into the bottle to increase the volume of the cavity and store more solute. The opaque tube greatly damages the overall appearance of the packaging bottle, prevents consumers from directly seeing the contents, and makes it impossible to test and supervise the contents during production, thus affecting quality control.

[0041] The preferred embodiments of the present invention will now be described in detail 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 aid in understanding the present invention, but does not constitute a limitation thereof.
[0042] In this article, "inner" and "outer" are defined with reference to the longitudinal center axis of the storage cap or packaging bottle. The position closer to the longitudinal center axis is considered inner, and the opposite is considered outer.
[0043] Figures 1 to 9 The diagrams are drawn to scale. To keep the instructions concise, the proportions of each component are not listed individually. However, the proportions and positions of each component should be considered part of the contents of this instruction manual.
[0044] Figures 1 to 9 An embodiment of a long tubular storage lid 100 and a packaging bottle using the storage lid are shown. The storage lid 100 can independently store liquid or solid substances, such as honey, concentrated fruit juice, solid powder, etc. The packaging bottle includes a bottle 200 and the aforementioned storage lid 100. The bottle 200 has a bottle mouth 201, and the storage lid 100 is disposed on the bottle mouth 201. When the storage lid 100 is in its initial closed state, the substance inside the storage lid 100 can be stored independently, separated from the liquid (e.g., water) inside the bottle 200, such as… Figure 5 As shown. When the storage lid 100 is in the open position, the substance inside the storage lid 100 can flow out and into the bottle 200 below, where it mixes with the liquid inside the bottle 200, such as... Figures 7 to 9 As shown. Among them, in Figure 9 In the state shown, the contents of the storage lid 100 and the liquid in the bottle 200 are mixed, for example, to form honey water. The drinking spout of the storage lid 100 is exposed and can be drunk from the spout, and the liquid in the bottle 200 can flow out from the drinking spout.
[0045] Reference Figures 1 to 9As shown, the long tubular storage cap 100 includes a screw cap 1, a lower cap 2, a storage tube 3, and a movable component 4. The storage tube 3 is a long tube that extends into the bottle 200; the storage tube 3 has a cavity 30 for containing substances. The lower cap 2 fixes the storage tube 3 to the mouth of the bottle 200, and the screw cap 1 is detachably connected to the lower cap 2, closing or exposing the top of the cavity 30 of the storage tube 3. The movable component 4 is movably disposed within the storage tube 3; specifically, the movable component 4 is rotatable and movable up and down in the cavity 30. The lower cap 2, the storage tube 3, and the movable component 4 are all transparent; for example, the lower cap 2 is made of polypropylene, the storage cap 100 is made of polypropylene, and the movable component 4 is made of polypropylene. When the storage tube 3 is installed on the bottle 200, the portion extending into the bottle 200 is transparent, allowing consumers or manufacturers to visually see the condition of the storage cap 100 from outside the bottle 200.
[0046] The structure of each component is described in detail below.
[0047] The screw cap 1 is fitted onto the upper part of the lower cover 2, and the two are connected by a threaded seal. The screw cap 1 is made of a material with good elasticity, such as high-density polyethylene (HDPE), to ensure a good seal between the screw cap 1 and the lower cover 2. The middle part of the screw cap 1 also has a downwardly extending connecting edge 11, which is inserted into the top end of the movable part 4. The connecting edge 11 can drive the movable part 4 to rotate, and the connecting edge 11 and the movable part 4 can also be separated from each other. In this embodiment, a ratchet is provided on the outer surface of the connecting edge 11, and pawls 46 are provided at intervals on the inner surface of the top end of the movable part 4. The pawls 46 cooperate with the ratchet. When the screw cap 1 rotates in a first direction, it drives the movable part 4 to rotate. When the screw cap 1 rotates in a second direction, the screw cap 1 and the movable part 4 slip against each other. The second direction is opposite to the first direction. With this configuration, the consumer can only open the screw cap 1 in the first direction (e.g., counterclockwise), and cannot open the screw cap 1 by rotating in the opposite direction. In other embodiments, a pawl may be provided on the outer surface of the connecting edge 11, and a ratchet may be provided on the inner surface of the top end of the moving part 4, with the pawl and ratchet cooperating with each other.
[0048] The lower cap 2 is threaded onto the bottle opening 201, connecting the storage cap 100 and the bottle 200. The lower cap 2 has an inner skirt 21 that extends into the bottle opening 201 of the bottle 200, located between the storage tube 3 and the movable component 4. The lower cap 2 also includes an outer cylinder 22 and an inner cylinder 23, with the outer cylinder 22 located outside the inner skirt 21. The upper end of the outer cylinder 22 is open, forming a protruding drinking spout. A screw cap 1 is specifically fitted onto the upper end of the outer cylinder 22 and sealed by threads; when the screw cap 1 is unscrewed, the drinking spout is exposed. The lower end of the outer cylinder 22 is fitted onto the bottle opening 201 of the bottle 200 and sealed by threads. The inner cylinder 23 is connected above the inner skirt 21 and has internal threads. The upper end of the inner cylinder 23 is lower than the upper end of the outer cylinder 22. After the storage cap 100 is installed on the bottle mouth 201, the lower end of the inner skirt 21 will not extend beyond the neck of the bottle 200. Furthermore, the lower end of the inner skirt 21 is level with the lower end of the bottle mouth 201, or even slightly higher than the lower end of the bottle mouth 201.
[0049] The upper end of the storage tube 3 is open and has a flange 31, which is configured to be pressed against the bottle opening 201 of the bottle 200 by the lower cap 2. The flange 31 may be a horizontal plate that mates with the upper surface of the bottle opening 201. A first elastic layer 5 is provided on the upper end of the storage tube 3, and a portion of the first elastic layer 5 is located between the flange 31 and the lower cap 2. The first elastic layer 5 is made of an elastic material, thereby ensuring a good seal between the storage tube 3 and the lower cap 2. The upper end of the storage tube 3 has an upward-facing first stepped surface 33, and the first elastic layer 5 extends from the upper surface of the flange 31 to the first stepped surface 33. Adapting to the height of the inner skirt 21 of the lower cap 2, the first stepped surface 33 and the lower end of the inner skirt 21 are level, or the first stepped surface 33 is slightly lower than the lower end of the inner skirt 21, so that the first elastic layer 5 is substantially covered by the bottle opening 201, and the portion covered by the first elastic layer 5 is substantially located inside the bottle opening 201 of the bottle 200.
[0050] The movable member 4 has a top end, a bottom end, and a neck 41 located between the top end and the bottom end. The top end can engage with the screw cap 1, that is, the connecting edge 11 of the screw cap 1 is inserted into the top end of the movable member 4. The movable member 4 is also threadedly connected to the lower cover 2 so as to be driven to rotate by the screw cap 1 and move downward relative to the lower cover 2. Specifically, the top end of the movable member 4 is provided with an external thread 45, which is inserted into the inner cylinder 23 of the lower cover 2. The external thread 45 and the internal thread 231 of the inner cylinder 23 cooperate with each other. Under the action of the thread, the movable member 4 moves downward while rotating.
[0051] A second elastic layer 6 is provided on the outer surface of the neck 41. The neck 41 is generally truncated cone-shaped, with a smaller outer diameter at the top and a larger outer diameter at the bottom. Specifically, the neck 41 of the movable member 4 has a second stepped surface 411 and a third stepped surface 412 facing upwards. The second stepped surface 411 is higher than the third stepped surface 412, and the second elastic layer 6 extends from the second stepped surface 411 to the third stepped surface 412. To adapt to the height of the inner skirt 21 of the lower cover 2, the lower end of the third stepped surface 412 is level with the lower end of the inner skirt 21, or the third stepped surface 412 is slightly lower than the lower end of the inner skirt 21, so that the second elastic layer 6 is basically covered by the bottle mouth 201, and the part covered by the second elastic layer 6 (i.e., the neck 41) is basically located inside the bottle mouth 201 of the bottle 200.
[0052] The outer surface of the inner skirt 21 contacts the first elastic layer 5 to further improve the sealing performance between the lower cover 2 and the storage tube 3. The inner surface of the inner skirt 21 contacts the second elastic layer 6 to improve the sealing performance between the lower cover 2 and the moving part 4. A first through hole 34 is provided on the upper end of the storage tube 3, a second through hole 211 is provided on the inner skirt 21, and a third through hole 42 is provided on the top end of the moving part 4, the third through hole 42 being higher than the second elastic layer 6. The storage cover 100 has a closed cavity state and a closed cavity state. In the closed cavity state, the second through hole 211 is covered by the second elastic layer 6; in the open cavity state, the third through hole 42 and the second through hole 211 are flush, and the first through hole 34, the second through hole 211, and the third through hole 42 connect the spaces on the inner and outer sides of the storage tube 3. In the closed cavity state, at least a portion of the first through hole 34 and the second through hole 211 are aligned with each other, and the first through hole 34 and the second through hole 211 are interconnected.
[0053] The bottom of the storage tube 3 includes a puncture portion 32, which is surrounded by an annular thin adhesive portion with an annular groove, thereby reducing the thickness and strength of the adhesive portion. The lower end of the movable part 4 has a sharp cutting portion 44, which is located directly above the thin adhesive portion. When the storage cap 100 is in the open position, the screw cap 1 and the lower cap 2 are separated, and the lower end of the movable part 4 is open to allow the liquid in the bottle 200 to flow out. The movable part 4 is a hollow cylindrical body with open upper and lower ends. The storage tube 3 is fitted over the movable part 4. When the movable part 4 punctures the bottom of the storage tube 3, a portion of the movable part 4 moves to below the storage tube 3. The movable part 4 is also provided with multiple fourth through holes 43, which are distributed below the neck 41. The fourth through holes 43 facilitate the flow of substances inside and outside the cavity 30.
[0054] In some other examples, the bottom of the storage tube 3 is open and sealed by a sealing film that can be punctured by the cutter part 44. In other embodiments, the bottom of the movable member 4 is closed and plugged, while the bottom of the storage tube 3 is open and plugged by the movable member 4. When the movable member 4 moves downward, a gap is formed between the movable member 4 and the storage tube 3, allowing the cavity 30 to open.
[0055] The lower outer surface of the movable part 4 is provided with an outwardly protruding limiting rib, and the bottom of the storage tube 3 has an upwardly facing limiting part. The limiting rib is restricted above the limiting part to prevent the movable part 4 from detaching from the storage tube 3 and falling into the bottle 200.
[0056] The first elastic layer 5 comprises a thermoplastic elastomer (TPE) layer, and the first elastic layer 5 and the lower cap 2 are integrally formed by a two-injection molding process. The second elastic layer 6 comprises a thermoplastic elastomer layer, and the second elastic layer 6 and the moving part 4 are integrally formed by a two-injection molding process. In some examples, a third elastic layer 7 is provided on the lower surface of the flange 31 to improve the sealing performance between the flange 31 and the bottle mouth 201. The third elastic layer 7 comprises a thermoplastic elastomer layer, which may be integral with the first elastic layer.
[0057] The length of the storage tube 3 is more than 80% of the length of the storage cap 100 when the cavity is closed. This fully utilizes the space within the bottle 200, resulting in a larger volume of the cavity 30 without increasing the volume of the portion of the storage cap 100 protruding from the bottle opening 201, thus maintaining the overall aesthetic appeal of the packaging bottle. The larger cavity 30 allows for the storage of a greater amount of solute, resulting in a higher concentration and better taste when the solute mixes with the liquid inside the bottle 200.
[0058] In this embodiment, the length of the portion of the storage cap 100 located below the bottle opening 201 is more than 1.5 times, preferably more than 2 times, the length of the portion located above the bottle opening 201. This allows the space inside the bottle 200 to be used to increase the volume of the cavity 30 without affecting the overall appearance of the packaging bottle or damaging the aesthetics of the packaged product.
[0059] The storage cover 100 in this embodiment is used as follows:
[0060] 1. Filling: First, screw the movable part 4 into the lower cover 2, then fasten the storage tube 3 to form a container with an open top. Pour liquid into the container from the top of the movable part 4, and finally tighten the cap 1. When the storage cap 100 is assembled onto the bottle 200, the storage tube 3 extends into the bottle mouth 201, and its flange 31 hangs on the bottle mouth 201. The lower cover 2 is screwed onto the bottle mouth 201 until it presses the flange 31 tightly against the bottle mouth 201, thus sealing the storage cap 100 and the bottle mouth 201. Figure 5 As shown.
[0061] 2. Preparation: Rotate the cap 1 in the first direction (counterclockwise). Under the action of the ratchet, the moving part 4 rotates. Due to the thread action, the cap 1 and the moving part 4 move in opposite directions. The moving part 4 moves downward, and the cutting part 44 on the moving part 4 punctures the thin rubber part at the bottom of the storage tube 3, further pushing out the punctured part 32. The substance in the storage tube 3 flows downward into the bottle 200, such as... Figure 7 As shown. Then, screw the cap 1 back onto the lower cap 2, and shake the bottle 200 to mix the contents, as shown. Figure 8 As shown.
[0062] 3. Drinking: Unscrew cap 1, the drinking spout at the top of the lower cap 2 will be exposed, and the liquid inside bottle 200 will flow out along the spout. Figure 9 The liquid flows out in the direction indicated by the middle arrow. Among them, a small amount of liquid near the edge corner of the bottle 200 can flow out through the first through hole 34, the second through hole 211 and the third through hole 42 on the side of the storage cap 100, which prevents the liquid from not flowing out when the amount of liquid in the bottle 200 is small, and solves the problem of residual liquid in the bottle 200.
[0063] The storage cap 100 and packaging bottle of this embodiment utilize the flange 31 of the storage tube 3 and the first elastic layer 5 to achieve a seal between the storage tube 3 and the lower cap 2, and the second elastic layer 6 of the movable part 4 to achieve a seal between the storage tube 3 and the movable part 4. This allows the components of the storage cap 100 inserted into the bottle 200 (including a portion of the lower cap 2, the storage cap 100, and the movable part 4) to be made of transparent material (e.g., polypropylene), making it easy to observe the substances in the cavity 30 and monitor changes in the material within the bottle 200, while ensuring good sealing performance of the storage cap 100 and maintaining the aesthetics of the packaging. The first through hole 34 to the third through hole 42 ensure that a small amount of liquid in the bottle 200 can be poured out during drinking, preventing liquid from flowing out and remaining in the bottle 200. The insertion of the storage tube 3 into the bottle 200 utilizes the space within the bottle 200 to obtain a larger cavity 30, storing more solute, increasing the solute concentration of the liquid in the bottle 200 after mixing, and improving the taste.
