Description

Technical Field

[0001] The utility model belongs to the technical field of food packaging and relates to a spiral puncture type storage cover and a packaging bottle. Background Art

[0002] The storage cap can independently store solutes such as liquids or solid powders and can be attached to the bottle opening. When needed, the storage cap is opened to allow the solute in the storage cap to fall into the bottle, mixing the two. For example, the bottle cap disclosed in patent CN119796698A by the applicant includes a storage bin, a puncture post, and a screw cap. The screw cap is threadedly connected to the drinking opening of the storage bin. When the screw cap is rotated to move the puncture post downward to open the storage bin, the screw cap also moves upward in the opposite direction. Therefore, the screw cap needs to be rotated in the opposite direction to reseal it to the drinking opening before the bottle can be shaken to mix the solute and the liquid in the bottle. Otherwise, when the bottle is shaken, the liquid will leak through the gap between the drinking opening and the screw cap.

[0003] Another example is the bottle cap disclosed in patent CN219566100U by the applicant, which includes a bottle cap body, an upper cover, a lower barrel, and an inner barrel. When the bottle cap is in a closed state, the cover is located within the lower end of the lower barrel to seal it. When the bottle cap is in an open state, a gap is formed between the cover and the lower end of the lower barrel, through which the solute in the solute cavity can flow into the bottle, thereby achieving mixing of the solute and the liquid in the bottle. Although this bottle cap does not require the upper cover to be screwed back onto the bottle cap body after the cover is removed, this type of bottle cap has the following problems: when drinking, the bottle cap body and the upper cover need to be separated from the lower barrel and the inner barrel, and then the bottle cap body and the upper cover need to be separated from the bottle mouth, which is not convenient to use.

[0004] Therefore, a storage cap that is more convenient to use is needed, which does not require the screw cap to be screwed back after the storage compartment is opened, nor does it require the bottle cap body to be separated from the bottle mouth when drinking. Utility Model Content

[0038] 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.

[0039] Reference Figures 1 to 8 , the embodiment provides a spiral puncture storage cap 100, which can independently store liquid or solid substances, such as honey, juice concentrate or seasoning. The embodiment also relates to a packaging bottle, which includes a bottle 200 and the above-mentioned storage cap 100. The bottle 200 has a bottle mouth, and the storage cap 100 is arranged on the bottle mouth. When the storage cap 100 is in the initial state, the substance in the storage cap 100 can be stored independently and separated from the liquid (such as water) in the bottle 200. When the storage cap 100 is in the open state, the substance in the storage cap 100 can flow out, for example, into the bottle 200 below and mix with the liquid in the bottle 200.

[0040] The spiral puncture storage cap 100 includes a storage bin 1, an upper cover 2, a puncture post 3, and a rotating member 4. The storage bin 1 is made of polyethylene, the upper cover 2 is made of polyethylene, the puncture post 3 is made of polypropylene, and the rotating member 4 is made of polypropylene. The materials of each component have a certain degree of elasticity. In particular, the storage bin 1 and the rotating member 4 are tightly assembled into one body, and there is a good sealing performance between the two. The storage bin 1 can be connected to the bottle mouth of the bottle 200. The storage bin 1 contains a storage cavity 10. The bottom of the storage bin 1 is closed by a sealing portion 11 to separate it from the liquid in the bottle 200. The puncture post 3 is movably arranged in the storage cavity 10. The puncture post 3 can push out or puncture the sealing portion 11, thereby opening the storage cavity 10 and allowing the substances in the storage cavity 10 and the liquid in the bottle 200 to contact and mix with each other. The sealing portion 11 can be a sealing film, such as aluminum foil, which can be punctured by the puncture post 3.

[0041] Combine Figure 4 The rotating member 4 includes an outer cylinder 41 and an inner spiral member 42 located inside the outer cylinder 41. The outer cylinder 41 can be rotatably sleeved on the storage bin 1. The upper cover 2 is connected to the upper part of the outer cylinder 41 and can rotate with the rotating member 4. The inner spiral member 42 has a first thread 421, and the puncture column 3 has a second thread 31. The inner spiral member 42 and the puncture column 3 are connected by the first thread 421 and the second thread 31. When the storage bin 1, the upper cover 2, the puncture column 3 and the rotating member 4 are assembled into one body, basically only the upper cover 2 and the rotating member 4 are exposed, while the storage bin 1 and the puncture column 3 are located inside the rotating member 4. When the storage chamber 10 needs to be opened, the rotating member 4 is screwed in the set direction. Under the cooperation of the first thread 421 and the second thread 31, the rotating member 4 and the puncture column 3 move in opposite directions, wherein the rotating member 4 moves upward and the puncture column 3 moves downward, puncturing or ejecting the sealing portion 11 below. During this process, the upper cover 2 and the rotating member 4 can move synchronously, and the upper cover 2 rotates and moves upward along with the rotating member 4 .

[0042] The outer tube 41 is a cylindrical body with open ends at both ends. The outer diameter of the upper end of the outer tube 41 is smaller, forming a structure similar to the mouth of a bottle, which facilitates drinking the liquid in the bottle 200 from the upper end of the outer tube 41. Furthermore, the outer surface of the upper end of the outer tube 41 is provided with an external thread, which is threadedly connected to the upper cover 2, thereby sealing the upper end of the storage chamber 10 through the upper cover 2. When the upper cover 2 is removed, the upper end of the outer tube 41 is exposed, making it convenient to drink the liquid in the bottle 200. The outer diameter of the lower end of the outer tube 41 is larger, preferably equal to the outer diameter of the bottle 200, so that the lower end of the outer tube 41 can engage with the shoulder of the bottle 200 to avoid damaging the overall design of the bottle 200.

[0043] like Figure 4 and Figure 6The rotating member 4 also includes a first connecting skirt 43 and a first sealing skirt 44. The first connecting skirt 43 surrounds the first sealing skirt 44, and an annular mounting gap 45 is formed between the first connecting skirt 43 and the first sealing skirt 44, and the upper part of the storage bin 1 is inserted into the annular mounting gap 45. The first sealing skirt 44 has a first sealing flange 441 protruding toward the outside, and the first sealing flange 441 is pressed against the inner surface of the upper part of the storage bin 1. The height of the first sealing skirt 44 is greater than the distance the rotating member 4 moves upward when the storage cavity 10 is opened. The first connecting skirt 43 is provided with a third thread 431 which is an internal thread, and the storage bin 1 is provided with a fourth thread 15 which is an external thread. The first connecting skirt 43 and the storage bin 1 are connected by the third thread 431 and the fourth thread 15; the number of turns of the third thread 431 and / or the fourth thread 15 is multiple. During the rotation of the rotating member 4, the third thread 431 and the fourth thread 15 remain engaged and connected, preventing them from disengaging. Furthermore, the first sealing flange 441 always abuts the inner surface of the storage bin 1. This ensures a good seal between the storage bin 1 and the rotating member 4, preventing leakage. Furthermore, the first sealing skirt 44 is configured to be outwardly biased. When the upper portion of the storage bin 1 is inserted into the annular mounting gap 45, the first sealing skirt 44 is slightly pressed inward, creating an interference fit between the two, ensuring that the first sealing flange 441 always maintains close contact with the inner surface of the storage bin 1.

[0044] like Figure 2 As shown, the puncture column 3 is hollow and open at both ends. A through hole 30 is provided on the sidewall of the puncture column 3 for the circulation of liquid or powder. The inner spiral member 42 and the puncture column 3 are plugged into each other. Specifically, in the example shown in the accompanying drawings, the inner spiral member 42 can be rotated to slide into the puncture column 3. In other embodiments, the puncture column 3 can be inserted into the inner spiral member 42. The bottom of the puncture column 3 has a puncture portion 32 with an increased outer diameter and a retaining rib 33 located above the puncture column 3. An annular groove 34 is defined between the puncture portion 32 and the retaining rib 33. When the storage bin 1 is opened, the bottom of the storage bin 1 is located in the annular groove 34.

[0045] like Figure 3 and Figure 6The storage cap 100 is threadedly connected to the bottle opening of the bottle 200. Specifically, the storage bin 1 includes a second connecting skirt 12 and a second sealing skirt 13. The second connecting skirt 12 is provided with internal threads that mate with the threads on the bottle opening of the bottle 200. The second connecting skirt 12 surrounds the second sealing skirt 13, with an annular connection gap 14 between the two. The second sealing skirt 13 is provided with an outwardly extending second sealing flange 131. When the storage cap 100 is assembled onto the bottle 200, the bottle opening of the bottle 200 is inserted into the annular connection gap 14. The threads and the second sealing flange 131 ensure a good seal between the storage cap 100 and the bottle opening of the bottle 200, preventing liquid leakage.

[0046] The storage cover 100 has a drinking state, such as Figure 8 After the drinking state, the upper cover 2 is separated from the rotating member 4. During the conversion of the storage cover 100 from the initial state to the drinking state, Figure 5 The state shown transitions to Figure 7 The status shown is Figure 8 During the state shown, the upper cover 2 is fixed relative to the rotating member 4 .

[0047] The use process of the storage cover 100 is described as follows:

[0048] In the initial state, combined Figure 1 、 Figure 5 and Figure 6 As shown, the storage bin 1 is not opened, the upper end of the storage cavity 10 is closed by the upper cover 2, the sealing portion 11 at the bottom of the storage cavity 10 is not punctured or ejected, the lower end of the storage cavity 10 is closed by the sealing portion 11, and most of the puncture column 3 is inserted into the inner spiral part 42 of the rotating part 4.

[0049] When you need to open the storage compartment 1, Figure 7 The rotating member 4 is screwed as shown by the arrows on both sides of the storage cover 100, and the rotating member 4 and the puncture column 3 move in opposite directions under the cooperation of the first thread 421 and the second thread 31, and the puncture column 3 moves downward to puncture the sealing portion 11, as shown in FIG. Figure 7 As indicated by the arrows within storage cap 100, the substance within storage cap 100 can flow into bottle 200 through through-hole 30 in piercing post 3 and the gap between piercing post 3 and the bottom of storage chamber 1. During this process, upper cap 2 remains engaged with rotating member 4, rotating and moving upward a certain distance with the rotating member 4 to seal the upper portion of storage chamber 10. Simultaneously, the upper portion of storage chamber 1 remains connected to rotating member 4 (inserted into annular mounting gap 45), maintaining a good seal. Therefore, bottle 200 can be shaken directly to evenly mix the substance (e.g., honey) with the liquid.

[0050] When drinking mixed liquids (nectar drinks), such as Figure 8As shown by the middle arrow, the upper cover 2 is screwed on to rotate the upper cover 2 relative to the rotating member 4. The upper cover 2 can be detached from the rotating member 4, exposing the upper end of the outer cylinder 41. Liquid can be drunk from the upper end of the outer cylinder 41. When drinking, each connection maintains good sealing performance and there will be no leakage problem.

[0051] The spiral piercing storage cap 100 of the embodiment has the following advantages: after the storage chamber 10 is opened, the bottle 200 can be directly shaken to evenly mix the liquid, eliminating the need to reversely rotate the screw cap to reseal it to the drinking opening as in patent CN119796698A before shaking the bottle to mix the solute with the liquid. When drinking is ready, the upper cap 2 is separated from the rotating member 4, exposing the top of the outer cylinder 41, making it convenient to use; unlike patent CN219566100U, which requires separating both the bottle cap body and the upper cap from the bottle opening, the bottle can be shaken to mix the solute with the liquid.
