TECHNICAL FIELD

[0001] The utility model relates to bottle cap technical field especially, it relates to a sealed bottle cap of built -in trigger type containing cavity. BACKGROUND

[0002] With the market to the wine drinking innovation experience strengthens, hope through the product realizes 1+1 fusion purpose promotion experience, that is, through the material (such as: original liquid or flavoring material etc.) storage in bottle cap, and before uncapping with wine body is isolated, then in the process of wine opening bottle cap, realize the material injection in built -in to wine body, realize built -in material and the natural fusion of wine body, promotion consumer experience.

[0003] At present, there are some bottle caps that can be used to store materials in the packaging bottles of other beverages. For example, the invention patent with the publication number CN105667986A discloses a bottle cap assembly for storing solid beverage, which comprises a material bin arranged below the top cap and a feeding pressure rod arranged inside the top of the top cap. Before drinking, the top cap can be pressed downward, and the feeding pressure rod can be used to pierce the upper and lower surfaces of the material bin, so that the solid beverage particles can enter the solvent in the bottle. However, the bottle cap has the following disadvantages: when using the beverage, there is no correlation between the two steps of pressing the feeding pressure rod and opening the bottle cap, and it is possible to forget to feed the material, which affects the convenience of use. The press-type trigger structure is used to pierce the material bin, and it is possible to accidentally touch the trigger structure during packaging and transportation. In addition, because the feeding pressure rod needs to pierce the upper and lower surfaces of the material bin, the sealing material used in the material bin may be relatively thin and have poor stability, which limits the storage of materials, and the capacity is also limited. CONTENT OF THE UTILITY MODEL

[0004] In order to overcome the above-mentioned deficiencies of the existing bottle cap that can store materials, the technical problem to be solved by the utility model is to provide a sealed bottle cap with a built-in trigger type containing cavity, which is more convenient to trigger and has a more stable structure.

[0005] The utility model solves the technical problems by adopting the following technical scheme:

[0006] A sealed bottle cap with a built-in trigger type containing cavity, comprising an upper cap, a lower cap, an inner plug and a rotating column.

[0007] The lower end of the lower cap is provided with a connecting structure that can be fixed with the periphery of the bottle mouth, and the upper cap and the lower cap are connected by a first threaded structure.

[0008] The inner plug can be embedded in the bottle mouth and sealedly connected with the bottle mouth, and a sealed containing cavity is formed between the inner plug and the lower cap and the upper cap.

[0009] The upper end of the screw-out column is connected with the threaded sleeve by the second threaded structure, and the end is in axial sliding fit with the transmission member, the rotation directions of the first threaded structure and the second threaded structure are opposite; when the upper cover is completely screwed, the lower end of the screw-out column is located inside the sealing plug; when the upper cover is rotated to open, the screw-out column rotates synchronously with the transmission member, and is axially displaced downward under the action of the second threaded structure and pushes open the sealing plug.

[0010] Further, the upper cover comprises an outer cover and an inner cover, the inner cover is coaxially fixed in the inner cavity of the outer cover, the transmission member is arranged inside the top of the inner cover, and an annular sealing groove is further arranged inside the top of the inner cover, the annular sealing groove is in interference sealing fit with the upper end of the lower cover when the upper cover is completely screwed, and the first threaded structure is arranged between the inner cover and the lower cover.

[0011] Further, the lower cover is composed of a coaxially nested outer sleeve and an inner sleeve, the lower end of the outer sleeve is provided with an annular clamping rib in interference fit with the bottle mouth, the upper end of the outer sleeve is fixedly connected with the lower end of the inner sleeve, and the first threaded structure is located between the inner cover and the inner sleeve; the lower end of the inner sleeve presses the annular shoulder on the upper end of the inner plug against the bottle mouth, and the inner wall of the inner sleeve and the outer wall of the upper end of the inner plug form a radial sealing fit.

[0012] Further, the inner sleeve is provided with a support frame in the upper half, the support frame is provided with a mounting hole in the middle and a hollow hole communicating with the upper and lower sides around the support frame, and the threaded sleeve is fixed in the mounting hole.

[0013] Further, the transmission member is a spline column arranged in the upper cover, and the top of the screw-out column is provided with a spline groove matched with the spline column.

[0014] Further, the length of the transmission member satisfies that when the upper cover is just unscrewed from the lower cover, the spline column is still not separated from the spline groove.

[0015] Further, the pitch of the first threaded structure is smaller than the pitch of the second threaded structure.

[0016] Further, the sealing plug comprises a plug body and a plug cover, the plug body is sealingly connected with the lower end opening of the inner plug, the plug cover is sealingly connected with the opening on the plug body, and the plug cover is connected with the plug body through a connecting strip.

[0017] The beneficial effects of this utility model are as follows: By incorporating an inner plug structure that can be embedded into the bottle mouth, the bottle mouth is sealed and protected on the one hand, and together with the upper and lower caps, an independent sealed cavity is formed, ensuring that the stored material (such as concentrate or flavoring substances) is completely isolated from the liquid in the bottle (such as wine) before triggering, avoiding moisture, oxidation or contamination of the material, and ensuring its stability and activity; by adopting two sets of oppositely spiraling thread structures (the first thread structure and the second thread structure), the bottle cap opening action and the material release triggering action are organically combined. When the upper cap is rotated to open, the screw-out column generates a downward axial displacement under the action of the threaded sleeve, pushing open the sealing plug at the bottom of the inner plug, realizing the integrated operation of "mixing upon opening the cap", which is convenient, quick and can avoid accidental triggering.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these are used to describe the relative positional relationships between components and are not specific references to the absolute positions of related components or the positional relationships between components. They are only used to explain the relative positional relationships and movement of components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. If this utility model contains terms related to quantity, such as "many," "multiple," or "several," these specifically refer to two or more.

[0027] like Figure 1 As shown, the sealing bottle cap with a built-in trigger-type receiving cavity provided by this utility model includes an upper cover 1, a lower cover 2, an inner plug 3, and a screw-out post 4; the lower end of the lower cover 2 is provided with a connection structure that can be fixed to the outer periphery of the bottle mouth 5; the upper cover 1 and the lower cover 2 are screwed together by a first threaded structure 6; the inner side of the top of the upper cover 1 is provided with a transmission component 13; the upper half of the inner part of the lower cover 2 is provided with a threaded sleeve 7 with internal threads; the inner plug 3 can be embedded in the bottle mouth 5 and is sealed to the bottle mouth 5; the inner plug 3 forms a sealed receiving cavity with the lower cover 2 and the upper cover 1; the bottom of the inner plug 3 is provided with a... The device has an opening with a sealing plug 8 at the opening. The upper end of the screw-out column 4 is screwed into the threaded sleeve 7 via a second threaded structure 9, and this end forms an axial sliding fit with the transmission component 13, meaning that the two can slide along the axis but cannot rotate around the axis. The first threaded structure 6 and the second threaded structure 9 have opposite rotation directions. When the upper cover 1 is fully screwed in, the lower end of the screw-out column 4 is located inside the sealing plug 8. When the upper cover 1 is rotated open, the screw-out column 4 rotates synchronously with the transmission component 13 and, under the action of the second threaded structure 9, generates a downward axial displacement and pushes open the sealing plug 8.

[0028] This invention utilizes the sealed cavity formed by the inner plug 3, the lower cap 2, and the upper cap 1 to store materials. This not only seals the contents of the bottle but also ensures complete isolation between the stored materials and the liquid inside the bottle before triggering. The triggering process for opening the cavity is as follows: when the upper cap 1 is rotated to open the bottle, the upper cap 1 moves upward under the action of the first threaded structure 6. Driven by the transmission component 13, the screw-out pin 4 rotates synchronously and in the same direction as the upper cap 1. Since the first threaded structure 6 and the second threaded structure 9 rotate in opposite directions, the movement direction of the screw-out pin 4 is opposite to that of the upper cap 1. The screw-out pin 4 moves downward, thereby opening the sealing plug 8, allowing the materials in the cavity to fall into the bottle and mix with the liquid. This invention organically combines the bottle cap opening action with the material release triggering action, achieving an integrated "open and mix" operation that is convenient, quick, and avoids accidental triggering.

[0029] Bottle caps typically feature various designs. To reduce manufacturing complexity, the upper cap 1 can be configured as a combination of an outer cap 11 and an inner cap 12. These are manufactured separately, and then the inner cap 12 is coaxially fixed to the inner cavity of the outer cap 11. Specifically, a hot-pressing method can be used to connect and fix the two caps. The transmission component 13 is located on the inner top side of the inner cap 12, which also has an annular sealing groove 14. When the upper cap 1 is fully screwed on, the annular sealing groove 14 forms an interference seal with the upper end of the lower cap 2. The first threaded structure 6 is located between the inner cap 12 and the lower cap 2. The sealing structure formed by the annular sealing groove 14 and the upper end of the lower cap 2 improves the sealing performance of the cavity, preventing the material inside from becoming damp, oxidized, or contaminated, thus ensuring its stability and activity.

[0030] Regarding the specific structure of the lower cover 2, as follows: Figure 2 As shown, the solution adopted in this utility model is that the lower cover 2 is composed of a coaxially nested outer sleeve 21 and an inner sleeve 22. The lower end of the outer sleeve 21 is provided with an annular retaining rib to form an interference fit with the bottle mouth, and its upper end is fixedly connected to the lower end of the inner sleeve 22. The first threaded structure 6 is located between the inner cover 12 and the inner sleeve 22. The outer sleeve 21 and the inner sleeve 22 can be integrally injection molded, or they can be manufactured separately and then fixed together by hot pressing. The inner plug 3 can be integrally injection molded with the inner sleeve 22, or it can be manufactured separately and then connected to the inner sleeve 22 by hot pressing, or as... Figure 3 As shown, the inner stopper 3 and the inner sleeve 22 are completely independent. First, the inner stopper 3 is fixed inside the bottle mouth 5, and axial positioning is achieved using the annular shoulder 31 on it. Then, when fixing the lower cap 2, the lower end of the inner sleeve 22 presses the annular shoulder 31 at the upper end of the inner stopper 3 against the bottle mouth 5. At the same time, the inner wall of the inner sleeve 22 and the upper outer wall of the inner stopper 3 form a radial sealing fit. Depending on the different structural forms of the inner stopper 3, in the wine packaging process, the material can be placed in the receiving cavity first, and then the entire bottle cap can be assembled and then hot-pressed onto the bottle mouth 5 by the outer sleeve 21. Alternatively, the inner stopper 3 can be installed on the bottle mouth 5 first, and then the material can be placed in the inner stopper 3. Finally, the assembled upper cap 1 and lower cap 2 can be pressed in.

[0031] For threaded sleeve 7, such as Figure 4 As shown, considering the difficulty of integral injection molding of the sleeve 22 with the inner sleeve 22, it is best to manufacture it independently first and then install it onto the inner sleeve 22. Specifically, a support frame 23 can be set in the upper half of the inner sleeve 22. The support frame 23 has a mounting hole 24 in the middle and hollow holes 25 around it connecting the upper and lower sides. The threaded sleeve 7 is fixed in the mounting hole 24. The threaded sleeve 7 and the mounting hole 24 can be connected by a limiting snap-fit ​​method. The hollow holes 25 are used to allow the wine in the bottle to flow out after the bottle cap is opened.

[0032] For the transmission component 13, a preferred embodiment of this utility model is that the transmission component 13 is a spline column disposed inside the upper cover 1, and the top of the screw-out column 4 is provided with a spline groove 41 that matches the spline column, such as... Figure 5 As shown. Furthermore, the length of the transmission component 13 ensures that when the upper cover 1 is unscrewed and just disengaged from the lower cover 2, the splined column remains in the spline groove 41. This splined column and spline groove 41 mating structure allows for axial sliding engagement between the transmission component 13 and the unscrewed column 4, as well as circumferential rotation restriction. Additionally, the length design of the transmission component 13 ensures that when the upper cover 1 is re-closed, it must first be inserted into the spline groove 41 before rotating the upper cover 1. If the transmission component 13 is too short, and the upper cover 1 engages with the lower cover 2 first, the transmission component 13 may not be able to be inserted into the spline groove 41, thus affecting the engagement of the upper cover 1. Furthermore, to allow the unscrewed column 4 to more quickly open the sealing plug 8 during the opening process, the pitch of the first thread structure 6 can be set to be smaller than the pitch of the second thread structure 9. This increases the moving speed and range of the unscrewed column 4, thereby better opening the sealing plug 8.

[0033] Regarding the specific structure of the sealing plug 8, the preferred embodiment of this utility model is as follows: Figure 6 As shown, the sealing stopper 8 includes a stopper body 81 and a stopper cap 82. The stopper body 81 is sealed and snapped into the lower opening of the inner stopper 3, and the stopper cap 82 is sealed and snapped into the opening on the stopper body 81. The stopper cap 82 is connected to the stopper body 81 via a connecting strip 83. During the packaging process, the bottle cap can be assembled first, and then the stopper cap 82 can be opened to fill the receiving cavity with material. Using the connecting strip 83 to connect the stopper cap 82 and the stopper body 81 can prevent the stopper cap 82 from falling into the bottle after the screw-out pin 4 opens it. At the same time, after the top cap 1 is opened, the position of the screw-out pin 4 will not change, ensuring that the stopper cap 82 is always in the open state when the screw-out pin 4 is turned on during the drinking process, without affecting the pouring of the wine.

[0034] In summary, this utility model adopts a first thread structure 6 and a second thread structure 9 with opposite rotation directions, which organically combines the bottle cap opening action with the material release triggering action, realizing an integrated operation of "mixing upon opening the cap". It is convenient, quick and can avoid accidental triggering, and has good practicality and application value.
