Description

Technical Field

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

[0002] Traditional bottled drinks are mostly prepared by premixing all the ingredients of the drink and then filling it into the bottle for storage. When drinking, just unscrew the bottle cap. However, this method often requires the addition of preservatives to extend the storage time of the drink, or the amount of preservatives added is relatively large. In response to this traditional packaging, bottle caps that can store liquids or solid powders independently have emerged. The liquid or solid powder pre-placed in the bottle cap is stored separately from the liquid in the bottle, and the two are mixed when needed.

[0037] The preferred embodiments of the present invention are described in detail below in conjunction with 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 used to help understand the present invention, but does not constitute a limitation of the present invention.

[0038] 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, and a beverage is formed after being evenly mixed. For example, in a specific example, the first content is honey and the second content is water. When it is needed to drink, the cavity of the bottle cap 100 is opened, so that the honey therein and the water in the bottle 200 are mixed to form honey water. In other examples, the first content can also be concentrated fruit juice or seasoning powder.

[0039] The bottle cap 100 includes a storage bin 1, a puncture column 2, and a screw cap 3. The bottle 200 includes a bottle body 202, which is generally cylindrical or prism-shaped. The diameter of the upper end of the bottle body 202 gradually decreases to form a bottle mouth 201, and the bottle cap 100 can seal the bottle mouth 201. The bottle mouth 201 is located above the bottle body 202, and the outer diameter of the bottle body 202 is greater than the outer diameter of the bottle mouth 201.

[0040] The storage bin 1 includes a shell 11 and a transverse partition 12. The transverse partition 12 is arranged in the shell 11 to enclose a cavity 110 for pre-setting the first content. The shell 11 has an upper end higher than the transverse partition 12 and a lower end lower than the transverse partition 12. The upper end is gradually reduced to form a neck 112. The neck 112 has a drinking port 111 connected to the cavity 110. The transverse partition 12 is provided with a communication port 120. The bottle cap 100 also includes a sealing member 13 capable of sealing the communication port 120. The sealing member 13 can be pierced or removed by the piercing column 2 to connect the cavity 110 with the inner cavity of the bottle 200 through the communication port 120. The piercing column 2 is located in the cavity 110. The bottle cap 100 also includes a stopper for limiting the piercing column 2 to move only in the up and down directions. The stopper is provided on the transverse partition 12 or the shell 11. The screw cap 3 is detachably connected to the neck 112, and includes a screw column 31 that can be inserted into the drinking port 111, the screw column 31 has a first thread 311, and the puncture column 2 has a second thread 21, and the screw column 31 and the puncture column 2 are connected by the first thread 311 and the second thread 21. The lower part of the storage bin 1 forms an outer sleeve 16 that can be sleeved on the side wall of the bottle body 202 of the bottle 200, and the bottle cap 100 also includes an inner sleeve 15 that can be sleeved on the bottle mouth 201 of the bottle 200, and the inner sleeve 15 is located on the inner side of the outer sleeve 16, and the inner sleeve 15 is arranged around the sealing member 13 and extends downward from the transverse partition 12.

[0041] 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. Fig.10 and Fig.11 As shown, after the screw cap 3 is rotated in a 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 to allow the first content in the cavity 110 to flow into the bottle 200. Fig.12 and Fig.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 port 111 is sealed by the screw cap 3 to allow shaking the bottle 200 to mix the first content flowing out and the second content therein.

[0042] like Figure 3 As shown, the limiting member includes a limiting sleeve 14 extending downward from the hole wall of the communication port 120, and the lower part of the puncturing column 2 is inserted into the limiting sleeve 14. One of the puncturing column 2 and the limiting sleeve 14 is provided with a limiting protrusion, and the other is provided with a limiting groove extending in the up-down direction, and the limiting protrusion can be slid up and down in the limiting groove relative to the limiting groove. Specifically, in the example shown in the drawings, the limiting sleeve 14 is provided with a plurality of limiting grooves 141 extending in the up-down direction, and the outer surface of the puncturing column 2 is provided with a plurality of limiting protrusions 22 protruding outward, and the limiting protrusions 22 can be inserted into the corresponding limiting grooves 141 movably in the up-down direction.

[0043] 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 tear groove 131 is provided between the sealing film and the limiting sleeve 14, and the thickness at the tear groove 131 is less than half of 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 tear 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, and the sealing film can be a metal foil or a plastic film, which can be punctured.

[0044] 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, and the limiting sleeve 14 is configured to be able 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 be engaged with the sealing thread on the bottle mouth 201 of the bottle 200 to achieve the fixation and sealing of the bottle cap 100 and the bottle mouth 201.

[0045] The bottom of the piercing column 2 has a conical piercing portion 23, and the upper part of the piercing portion 23 has a limiting rib 24. When the bottle cap 100 is in the second state or the third state, the bottom wall of the limiting sleeve 14 is limited below the limiting rib 24. Fig.11 and Fig.13 When the cavity 110 of the bottle cap 100 is opened for the first time, the puncture column 2 is restricted at a lower position. When the user pours the bottle 200 to drink the liquid in the bottle, the puncture column 2 is restricted in the housing 11 and will not escape from the limiting sleeve 14.

[0046] The piercing column 2 is hollow and open at both ends. A plurality of through holes 25 are provided on the side wall of the piercing column 2 to communicate with the cavity 110. When the sealing member 13 is pierced or removed, the through holes 25 can facilitate the first content in the cavity 110 to flow out along the Fig.10 and Fig.11 The arrow in FIG. 2 flows downward into bottle 200 .

[0047] The outer shell 11 and a substrate are integrally formed by two-color injection molding, wherein the transverse partition 12, the inner sleeve 15, the limiting sleeve 14 and the sealing member 13 are all formed by the substrate, and the outer sleeve 16 is formed by the lower end of the outer shell 11 and the lower end of the substrate. In another embodiment, the outer sleeve 16 can be formed only by the lower end of the outer shell 11 or the lower end of the substrate. The material of the outer shell 11 can be PP (polypropylene) or PE (polyethylene), and the material of the substrate can be PP or PE. The storage bin is made by the two-color encapsulation process, which has better sealing performance, avoids the risk of leakage, and has a more beautiful appearance.

[0048] The diameter of the communication port 120 and the inner diameter of the limiting sleeve 14 are smaller than the outer diameter and inner diameter of the outer sleeve 16. The ratio of the inner diameter of the communication port 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 diameter 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 size of the communication port 120 is designed to match the size of the bottle mouth 201 of the bottle 200, and the size of the outer sleeve 16 is designed to match the size of the bottle body 202 of the bottle 200, so that in terms of appearance, the storage bin itself can be combined with the bottle body 202 of the bottle 200 to form a larger "bottle" structure, and the proportion of the cavity 110 of the bottle cap 100 and the inner cavity of the bottle body 202 is more flexible, which solves the problem of the existing separate bottle cap 100 having a low solute concentration after the two parts of the content are mixed, and at the same time, the overall appearance design of the bottle 200 will not be damaged. 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.

[0049] 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 segment or an inclined inclined segment to form a transition segment.

[0050] In the example shown in the accompanying drawings, the first thread 311 is a spirally extended external thread, and the second thread 21 is a spirally extended internal thread. The first thread 311 and the second thread 21 are configured so that when the screw cap 3 rotates in a set direction, the spiral column 31 drives the puncture column 2 to move downward. When the bottle cap 100 is assembled on the bottle 200, the screw cap 3 is rotated in a set direction (clockwise or counterclockwise) for the first time, and the screw cap 3 is displaced in the up-down direction while rotating. The spiral column 31 of the screw cap 3 drives the puncture column 2 to move downward to puncture or remove the seal 13 (the first opening of the cavity 110); after the cavity 110 is opened for the first time, the spiral column 31 and the puncture column 2 maintain a state of being separated from each other, the first thread 311 and the second thread 21 will no longer bite each other, and the screw cap 3 can rotate freely independently of the puncture column 2, and can be screwed on the drinking opening 111 to seal it, or separated from the drinking opening 111 to expose the drinking opening 111 as needed.

[0051] Combination Figure 2 and Fig. 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 the annular groove 203 forms a limit, so that the bottom of the outer sleeve 16 is restricted in the annular groove 203.

[0052] The ratio of the volume of the cavity 110 to the volume of the bottle 200 is 1:(1-10). More preferably, the ratio of the volume of the cavity 110 to the volume of the bottle 200 is 1:(2-8); 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.

[0053] The method for mixing the contents of the packaging bottle comprises the following steps: (1) Rotating the screw cap 3 of the bottle cap 100 in a set direction to move the piercing column 2 downward, piercing or removing the sealing member 13, and connecting the cavity 110 of the bottle cap 100 with the inner cavity of the bottle 200; (2) rotating 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 shaking the bottle 200 so that the first content in the cavity 110 and the second content in the bottle 200 are mixed; (3) Rotate the screw cap 3 in a set direction to open the drinking opening 111.

[0054] In step (1), the bottle cap 100 is Figure 8 The first state shown transitions to Fig.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 film remains punctured or removed, the puncturing column 2 remains in its lower position, the first thread 311 no longer engages with the second thread 21, the screw cap 3 can rotate freely, and the puncturing column 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 at the same time, the drinking port 111 is exposed, and the inside and outside of the packaging bottle are connected, which is conducive to the first content in the cavity 110 flowing into the bottle 200. This design is particularly advantageous for relatively viscous honey.

[0055] In step (2), the bottle cap 100 is Fig.11 The second state shown transitions to Fig.13 In the third state shown, the conversion process is reversible. In the third state, the screw cap 3 seals the drinking opening 111 again, so that the packaging bottle can be shaken to mix the first content and the second content therein evenly. When mixed evenly, the packaging bottle has good sealing performance and effectively avoids leakage.

[0056] In step (3), the bottle cap 100 is Fig.13 The third state shown transitions to Fig.11 In the second state shown, the screw cap 3 can be removed, the drinking opening 111 is completely exposed, and the content in the packaging bottle can be poured out.
