Description

Technical Field

[0001] The invention relates to a detachable bottle cap, a packaging bottle and a method for mixing contents in the packaging bottle, in particular to a bottle cap with contents pre-placed therein, which can be mixed with liquid in the bottle body when needed. Background Art

[0002] Traditional bottled beverages are often packaged by premixing all ingredients, filling the bottle, and unscrewing the cap for consumption. However, this method often requires the addition of preservatives to extend the shelf life, or requires high amounts of preservatives. To address this traditional packaging, bottle caps designed to store liquids or solid powders have emerged. These pre-mixed liquids or solid powders are stored separately from the liquid in the bottle, allowing them to be mixed when needed.

[0003] Existing bottle caps capable of independently storing liquids or solids mostly store the liquid or solid inside the bottle cap. However, this has the disadvantage of limited storage space. The ratio of storage space inside the bottle cap to storage space inside the bottle is small, and this ratio is difficult to increase. This results in a low concentration of the liquid or solid inside the bottle cap after mixing with the liquid inside the bottle. Furthermore, bottle caps with pre-loaded liquids or solids are subject to certain limitations in appearance, making them difficult to coordinate with the bottle design and resulting in an unattractive appearance. Summary of the Invention

[0004] The present invention aims to provide a separable bottle cap and packaging bottle that solves the problems of low concentration after mixing the contents pre-placed in the bottle cap and the contents in the bottle, as well as the problem of unsightly appearance.

[0053] 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.

[0054] Reference Figures 1 to 13 As shown, this embodiment provides a detachable bottle cap 100 and a packaging bottle having such a bottle cap 100. The bottle cap 100 is pre-filled with a first content, and the bottle 200 of the packaging bottle contains a second content. After the cavity of the bottle cap 100 is opened, the first content can enter the bottle 200 and mix with the second content. After uniform mixing, a beverage is formed. For example, in one specific example, the first content is honey and the second content is water. When the beverage is ready for drinking, the cavity of the bottle cap 100 is opened, and the honey in the container and the water in the bottle 200 mix to form honey water. In other examples, the first content can also be concentrated fruit juice or seasoning powder.

[0055] The bottle cap 100 includes a storage compartment 1, a puncture post 2, and a screw cap 3. The bottle 200 includes a body 202, which is generally cylindrical or prismatic in shape. The diameter of the upper end of the body 202 tapers to form a mouth 201, which the bottle cap 100 seals. The mouth 201 is located above the body 202, and the outer diameter of the body 202 is larger than that of the mouth 201.

[0056] The storage bin 1 includes a housing 11 and a transverse partition 12. The transverse partition 12 is disposed within the housing 11 to enclose a cavity 110 for pre-filling a first content. The housing 11 has an upper end that is higher than the transverse partition 12 and a lower end that is lower than the transverse partition 12. The upper end tapers to form a neck 112, which has a drinking opening 111 that communicates with the cavity 110. The transverse partition 12 is provided with a communication opening 120. The bottle cap 100 also includes a seal 13 capable of sealing the communication opening 120. The seal 13 can be pierced or removed by a puncture post 2 to connect the cavity 110 with the inner cavity of the bottle 200 through the communication opening 120. The puncture post 2 is located in the cavity 110. The bottle cap 100 also includes a limiter for limiting the movement of the puncture post 2 to only in the vertical direction. The limiter is provided on the transverse partition 12 or the housing 11. The screw cap 3 is detachably connected to the neck 112 and includes a screw post 31 that can extend into the drinking opening 111. The screw post 31 has a first thread 311, and the puncture post 2 has a second thread 21. The screw post 31 and the puncture post 2 are matingly connected via the first thread 311 and the second thread 21. The lower portion of the storage compartment 1 forms an outer sleeve 16 that can be sleeved onto the sidewall of the bottle body 202 of the bottle 200. The bottle cap 100 also includes an inner sleeve 15 that can be sleeved onto the bottle opening 201 of the bottle 200. The inner sleeve 15 is located inside the outer sleeve 16, surrounds the seal 13, and extends downward from the transverse partition 12.

[0057] After the bottle cap 100 is connected to the bottle 200, the outer sleeve 16 of the bottle cap 100 is sleeved on the bottle body 202 of the bottle 200, and the inner sleeve 15 is sleeved on the bottle mouth 201 of the bottle 200 to seal the bottle mouth 201. Figures 7 to 13 As shown, the bottle cap 100 has three states. The rotating cap 3 can be transformed from the first state to the third state, and the transformation process from the first state to the second state is irreversible. Figure 7 and Figure 8 As shown, in the first state, the screw cap 3 is connected to the neck 112 to seal the drinking opening 111, the cavity 110 is in a closed state, and the first thread 311 of the spiral column 31 and the second thread 21 of the piercing column 2 are engaged with each other. Figure 10 and Figure 11 As shown, after the screw cap 3 is rotated in the set direction, the bottle cap 100 switches to the second state; at this time, the piercing column 2 is driven by the screw cap 3 to pierce or remove the sealing member 13 downward, allowing the first content in the cavity 110 to flow into the bottle 200. Figure 12 and Figure 13 As shown, after the screw cap 3 is rotated in the reverse direction, the bottle cap 100 switches to the third state; at this time, the first thread 311 of the spiral column 31 and the second thread 21 of the piercing column 2 are disengaged from each other, and the drinking opening 111 is sealed by the screw cap 3, so as to allow the bottle 200 to be shaken to mix the first content flowing out and the second content therein.

[0058] like Figure 3 As shown, the retaining member includes a retaining sleeve 14 extending downward from the wall of the communication port 120, into which the lower portion of the puncturing post 2 is inserted. One of the puncturing post 2 and the retaining sleeve 14 is provided with a retaining protrusion, while the other is provided with a retaining groove extending in the vertical direction. The retaining protrusion is slidably disposed in the retaining groove relative to the retaining protrusion. Specifically, in the embodiment shown in the drawings, the retaining sleeve 14 is provided with a plurality of retaining grooves 141 extending in the vertical direction. The outer surface of the puncturing post 2 is provided with a plurality of outwardly protruding retaining protrusions 22, which are vertically movable and inserted into corresponding retaining grooves 141.

[0059] The sealing member 13 is located at the bottom of the limiting sleeve 14. Specifically, the bottom wall 142 of the limiting sleeve 14 constitutes the bottom of the sleeve, and the sealing member 13 is connected to the bottom wall 142. Furthermore, the sealing member 13 includes a sealing film. The sealing film and the limiting sleeve 14 are integrally arranged, and a tearing groove 131 is provided between the sealing film and the limiting sleeve 14. The thickness at the tearing groove 131 is less than half the thickness of the sealing film and the bottom wall 142 of the limiting sleeve 14. The sealing film and the limiting sleeve 14 are integrally injection molded by plastic. When the sealing film is subjected to external force, the tearing groove 131 breaks and the sealing film is ejected. In another embodiment, the sealing film is attached to the bottom of the limiting sleeve 14. The sealing film can be a metal foil or a plastic film that can be punctured.

[0060] The inner sleeve 15 surrounds the outer side of the limiting sleeve 14, and a gap is formed between the inner sleeve 15 and the limiting sleeve 14 for the wall of the bottle mouth 201 of the bottle 200 to be inserted. The limiting sleeve 14 is configured to extend into the bottle mouth 201 of the bottle 200. Specifically, a sealing thread is provided on the inner side surface of the inner sleeve 15, which can interlock with the sealing thread on the bottle mouth 201 of the bottle 200 to achieve a fixed and sealed state between the bottle cap 100 and the bottle mouth 201.

[0061] The bottom of the puncture column 2 has a conical puncture portion 23, and a limiting rib 24 is provided above the puncture portion 23. When the bottle cap 100 is in the second state or the third state, the bottom wall of the limiting sleeve 14 is restricted below the limiting rib 24. Figure 11 and Figure 13 When the cavity 110 of the bottle cap 100 is opened for the first time, the puncture column 2 is restrained at a lower position. When the user pours the bottle 200 to drink the liquid in the bottle, the puncture column 2 is restrained in the housing 11 and will not escape from the limiting sleeve 14.

[0062] The puncture column 2 is hollow and open at both ends. The side wall of the puncture column 2 is provided with a plurality of through holes 25 communicating with the cavity 110. When the seal 13 is punctured or removed, the through holes 25 can facilitate the first content in the cavity 110 to flow out along the Figure 10 and Figure 11 The arrow in FIG. 2 flows downward into the bottle 200 .

[0063] The outer shell 11 and a base material are integrally molded using two-color injection molding. The transverse partition 12, inner sleeve 15, stop sleeve 14, and seal 13 are all formed from the base material. The outer sleeve 16 is formed from the lower ends of the outer shell 11 and the base material. In another embodiment, the outer sleeve 16 may be formed solely from the lower ends of the outer shell 11 or the base material. The outer shell 11 can be made of PP (polypropylene) or PE (polyethylene), and the base material can be made of either PP or PE. The two-color encapsulation process for the storage bin provides improved sealing, minimizes leakage risks, and enhances its appearance.

[0064] The diameter of the communication opening 120 and the inner diameter of the limiting sleeve 14 are smaller than the outer and inner diameters of the outer sleeve 16. The ratio of the inner diameter of the communication opening 120 to the inner diameter of the bottle mouth 201 of the bottle 200 is 1:(0.8-1.2), and the ratio of the outer or inner diameter of the outer sleeve 16 to the outer diameter of the bottle body 202 of the bottle 200 is 1:(0.9-1.1). In other words, the dimensions of the communication opening 120 are designed to match the dimensions of the bottle mouth 201 of the bottle 200, and the dimensions of the outer sleeve 16 are designed to match the dimensions of the bottle body 202 of the bottle 200. As a result, the storage bin itself can be combined with the bottle body 202 of the bottle 200 to form a larger "bottle" structure. This provides greater flexibility in the ratio between the cavity 110 of the bottle cap 100 and the inner cavity of the bottle body 202, resolving the problem of low solute concentration after mixing the two contents of the existing detachable bottle cap 100 while maintaining the overall design of the bottle 200. It should be noted that after the bottle cap 100 is joined to the bottle 200 , the space below the transverse partition 12 , that is, the space between the outer sleeve 16 and the inner sleeve 15 , cannot be used to store the contents.

[0065] The outer diameter and inner diameter of the upper portion of the shell 11 gradually decrease from bottom to top. In the vertical cross section of the bottle cap 100, the upper portion of the shell 11 has an overall arc-shaped arc section or an inclined inclined section, forming a transition section.

[0066] In the example shown in the accompanying drawings, the first thread 311 is a spirally extending external thread, and the second thread 21 is a spirally extending internal thread. The first and second threads 311 and 21 are configured so that when the screw cap 3 is rotated in a predetermined direction, the screw post 31 drives the piercing post 2 downward. After the bottle cap 100 is assembled on the bottle 200, the screw cap 3 is initially rotated in the predetermined direction (clockwise or counterclockwise). This rotation causes the screw cap 3 to move vertically, causing the screw post 31 of the screw cap 3 to drive the piercing post 2 downward, piercing or removing the seal 13 (initial opening of the cavity 110). After the cavity 110 is initially opened, the screw post 31 and the piercing post 2 remain disengaged, and the first and second threads 311 and 21 no longer engage. The screw cap 3 can rotate freely independently of the piercing post 2 and can be screwed onto the drinking opening 111 to seal it, or detached from it to expose it, as needed.

[0067] Combine Figure 2 and Figure 9 As shown, an inwardly recessed annular groove 203 is formed on the upper end of the bottle body 202, and the bottom of the outer sleeve 16 is located in the annular groove 203. When the bottle cap 100 is assembled to the bottle body 202, the outer sleeve 16 is sleeved on the bottle body 202 and is limited by the annular groove 203, so that the bottom of the outer sleeve 16 is restricted in the annular groove 203.

[0068] The ratio of the volume of the cavity 110 to the volume of the bottle 200 is 1:(1-10). More preferably, the ratio is 1:(2-8), and further 1:(2-4). In this embodiment, the ratio of the volume of the cavity 110 to the volume of the bottle 200 is significantly higher than that of the existing detachable bottle cap 100.

[0069] The method for mixing the contents of the packaging bottle comprises the following steps:

[0070] (1) Rotate the screw cap 3 of the bottle cap 100 in a set direction to move the puncture column 2 downward, puncture or remove the seal 13, and connect the cavity 110 of the bottle cap 100 with the inner cavity of the bottle 200;

[0071] (2) Rotate the screw cap 3 in the reverse direction so that the screw cap 3 seals the drinking opening 111 of the bottle cap 100, and shake the bottle 200 to mix the first content in the cavity 110 and the second content in the bottle 200;

[0072] (3) Rotate the screw cap 3 in the set direction to open the drinking opening 111.

[0073] In step (1), the bottle cap 100 is Figure 8 The first state shown transitions to Figure 11In the second state shown, the conversion process is irreversible. That is, after the bottle cap 100 is opened for the first time, the sealing membrane remains punctured or removed, the piercing post 2 remains in its lower position, the first thread 311 no longer engages the second thread 21, the screw cap 3 can rotate freely, and the piercing post 2 no longer moves with the screw cap 3. It should also be noted that after the bottle cap 100 is opened for the first time, the screw cap 3 rotates and moves upward, exposing the drinking port 111, connecting the inside and outside of the packaging bottle, and facilitating the flow of the first contents in the cavity 110 into the bottle 200. This design is particularly advantageous for relatively viscous honey.

[0074] In step (2), the bottle cap 100 is Figure 11 The second state shown transitions to Figure 13 In the third state shown, the conversion process is reversible. In the third state, the screw cap 3 re-seals the drinking opening 111, thereby allowing the bottle to be shaken to evenly mix the first and second contents. When mixed, the bottle has a good seal, effectively preventing leakage.

[0075] In step (3), the bottle cap 100 is Figure 13 The third state shown transitions to Figure 11 In the second state shown, the screw cap 3 can be removed, the drinking opening 111 is completely exposed, and the contents of the packaging bottle can be poured out.

[0076] The bottle cap 100 of this embodiment has an outer sleeve 16 that can be sleeved on the bottle body 202 of the bottle 200, so that the bottle cap 100 and the bottle body 202 of the bottle 200 are adapted in shape. The bottle cap 100 as a whole forms the upper part of the packaging bottle, and its outer diameter can be consistent or similar to that of the bottle body 202 of the bottle 200, which is convenient for the appearance design of the packaged product and the product is more beautiful; under this premise, the volume of the cavity 110 of the bottle cap 100 and the volume of the bottle 200 can be adjusted within a large proportional range, and the size of the cavity 110 of the bottle cap 100 can be adjusted according to the optimal concentration of the target beverage to obtain the best drinking experience such as taste, without damaging the overall appearance of the bottle 200; in addition, the bottle cap as a whole has good sealing performance, especially, the storage bin is an integrated plastic part formed by two-color overmolding, which reduces the risk of leakage between the outer shell and the partition of the storage bin.
