Description

Technical Field

[0001] This utility model relates to the technical fields of food and beverage, brewing, etc., and specifically to a bottle cap structure with storage function and a wine bottle. Background Technology

[0002] Currently, in the beverage, pharmaceutical, and chemical industries, there are some usage scenarios that require proper storage in the same container and timely release for mixing. For example, in the processing of baijiu (Chinese liquor), the bottle cap stores liqueur made from food and medicinal raw materials. When it is ready to be consumed, the liqueur is released and mixed with the liquor inside the bottle.

[0003] Chinese utility model patent CN222041329U discloses a bottle cap structure with a reservoir. Specifically, it includes a main cap and a secondary cap. The main cap has a first fastening part and a reservoir tube. The first fastening part has a first external thread, and the reservoir tube has a first internal thread, with the external and internal threads opening in opposite directions. The secondary cap includes a second fastening part and a connecting post fixed to the second fastening part. The second fastening part has a second internal thread that mates with the first external thread, and the connecting post extends into the reservoir tube. It also includes a filter with a second external thread that mates with the first internal thread. The upper end of the filter and the connecting post are connected by a torque-driven sliding interaction, and the bottom of the filter has a release valve. This design allows the connecting post to rotate relative to the main cap, causing the filter and secondary cap to move in opposite directions. Thus, when the secondary cap opens, the filter, along with the release valve, moves downwards and opens. Furthermore, the filter has a hole through which liquid can be poured out after the filter moves downwards.

[0004] The existing technical problems are as follows: the outlet is located on the filter, which makes manufacturing difficult. Furthermore, the filter needs to withstand torque, and the internal openings affect the structure's torque capacity. Therefore, the openings are generally small, making it difficult to balance the flow rate and product performance, and placing high demands on the structural materials. The release valve located below the filter makes filling the reservoir tube inconvenient. The reservoir tube is directly exposed, and when used for spirits, potential sediment can cause visual discomfort. The complex structure of each component makes manufacturing difficult. Utility Model Content

[0005] To overcome the problem that the filter in the existing reservoir-type bottle cap cannot balance the pouring flow and product performance, this utility model provides a bottle cap structure and wine bottle with storage function.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] The bottle cap structure with storage function includes a top cap and a storage compartment. A downward-extending torsion bar is located at the center of the top cap, and a release device is located at the lower end of the storage compartment. Rotating the top cap opens the release device. It also includes an inner cap with a first external thread at its upper end and a corresponding first internal thread on the top cap. The lower end of the inner cap is used for a fixed connection with the bottle neck. Furthermore, it includes a drive screw and a guide buckle. The drive screw has a second external thread, and the guide buckle has a corresponding second internal thread. The first external thread and the second internal thread have opposite directions. The storage compartment is fixedly connected inside the inner cap, and a liquid outlet channel is formed between the storage compartment and the inner cap. The guide buckle is fixed to the upper end of the storage compartment. The drive screw and the torsion bar are connected by a sliding interaction through torque, so that when the top cap rotates open relative to the inner cap, the torsion bar drives the drive screw downwards, thereby opening the release device.

[0008] In this application, by adding an inner cover, a liquid outlet channel is formed between the inner cover and the storage compartment, avoiding liquid outlet via a torsion bar. On the one hand, this avoids the need for high requirements on the internal openings and torque resistance of the transmission screw structure, balancing the liquid flow rate and product performance; on the other hand, it also makes the processing and implementation of each component more convenient.

[0009] In some embodiments, a fixed guide plate extends outward from the center of the storage compartment in the height direction. The storage compartment is fixedly connected to the inner cover through the fixed guide plate, and the fixed guide plate is provided with a liquid outlet.

[0010] In some embodiments, the upper end of the inner cap extends inward to form a bottle cap diaphragm, the bottle cap diaphragm abuts against a fixed guide buckle on its inward side, and the bottle cap diaphragm is provided with a liquid outlet.

[0011] In some embodiments, the guide buckle extends outward from the center to form a raised edge, the upper end face of the raised edge abuts against the bottle cap diaphragm, and the lower end face of the raised edge abuts against the storage compartment.

[0012] In some embodiments, the release device is a release buckle, one end of which is fixedly connected to the storage compartment; the release buckle is closable and configured at the lower end of the storage compartment, the storage compartment is relatively sealed when the release buckle is closed, and the storage compartment is connected to the lower space when the release buckle is open.

[0013] This utility model also provides a wine bottle, comprising a bottle body and a bottle cap structure. The bottle cap structure is a bottle cap structure with storage function as described in any of the above embodiments. The upper end of the bottle body is the bottle neck, and the inner cap lower tube is fixedly connected to the bottle neck.

[0014] In some embodiments, the bottle structure further includes an outer cap and an outer cap fastener, the outer cap and the outer cap fastener are weakly connected, the outer cap fastener is fixedly sleeved on the outside of the bottle neck, the outer cap and the top cap are fixedly connected, the height of the outer cap fastener is adapted to the storage space of the storage compartment, and the outer cap fastener is configured to be non-transparent.

[0015] The beneficial effects of this utility model are:

[0016] By adding an inner cover, a liquid outlet channel is formed between the inner cover and the storage compartment, avoiding liquid outlet via a torsion bar. This avoids the need for high requirements on the internal openings and torque resistance of the transmission screw structure, balancing liquid flow rate and product performance. Furthermore, it makes the manufacturing and implementation of each component more convenient. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] like Figure 1 As shown, this utility model provides a bottle cap structure and a wine bottle with storage function.

[0022] The bottle cap structure with storage function includes a top cover 4 and a storage compartment 12. The top cover 4 has a downwardly extending torsion bar 5 at its center, and the storage compartment 12 has a release device at its lower end. Rotating the top cover 4 can open the release device.

[0023] It also includes an inner cover 6, the upper end of which is provided with a first external thread, and the top cover 4 is provided with a corresponding first internal thread. The lower end of the inner cover 6 is used for a fixed connection with the bottleneck 13. It also includes a transmission screw 9 and a guide buckle 8, the transmission screw 9 having a second external thread, and the guide buckle 8 being provided with a corresponding second internal thread. The opening directions of the first external thread and the second internal thread are opposite.

[0024] In practice, the lower end of the torsion bar 5 is covered with deep vertical ridges, which match the concave grooves of the transmission screw 9, thereby realizing the transmission function.

[0025] The storage compartment 12 is fixedly connected inside the inner cover 6, and a liquid outlet channel is formed between the storage compartment 12 and the inner cover 6; the guide buckle 8 is fixed at the upper end of the storage compartment 12, and the transmission screw 9 and the torsion bar 5 are connected by torque sliding interaction, so that when the top cover 4 rotates and opens relative to the inner cover 6, the torsion bar 5 drives the transmission screw 9 to move downward, thereby opening the release device.

[0026] In this application, by adding an inner cover 6, a liquid outlet channel is formed between the inner cover 6 and the storage compartment 12, avoiding liquid outlet through the torsion bar 5. On the one hand, this avoids the need for high requirements on the internal openings of the transmission screw 9 structure and the torque resistance performance, balancing the liquid flow rate and product performance; on the other hand, it also makes the processing and implementation of each component more convenient.

[0027] In this embodiment, the contents 14 of the storage compartment 12 are liqueur with high nutritional value.

[0028] In this embodiment, a fixed guide plate 11 extends outward from the center of the storage compartment 12 in the height direction. The storage compartment 12 is fixedly connected to the inner cover 6 through the fixed guide plate 11, and the fixed guide plate 11 is provided with a liquid outlet hole.

[0029] The fixed guide plate 11 facilitates the fixed installation of the storage compartment 12 inside the inner cover 6. The fixed guide plate 11 is equipped with a liquid outlet position, which can be adapted to the liquid flow rate.

[0030] In this embodiment, the upper end of the inner cover 6 extends inward to form a bottle cap partition 7, the bottle cap partition 7 abuts against the fixed guide buckle 8 on one side inward, and the bottle cap partition 7 is provided with a liquid outlet hole.

[0031] The bottle cap is designed with a horizontal spacer 7 to facilitate the fixing of the guide buckle 8.

[0032] In this embodiment, the guide buckle 8 extends outward from the middle to form a raised edge, the upper end of the raised edge abuts against the bottle cap diaphragm 7, and the lower end of the raised edge abuts against the storage compartment 12.

[0033] By adding a raised edge in the middle of the guide buckle 8 and setting it as described above, the relative positions of the guide buckle 8 and the storage compartment 12 inside the inner cover 6 are fixed, which facilitates product assembly and ensures consistency among products.

[0034] In this embodiment, the release device is a release buckle 10, one end of which is fixedly connected to the storage compartment 12. The release buckle 10 is configured to open and close at the lower end of the storage compartment 12. When the release buckle 10 is closed, the storage compartment 12 is relatively sealed. When the release buckle 10 is open, the storage compartment 12 is connected to the lower space.

[0035] The release buckle 10 makes the filling and opening / closing of the liqueur in the storage compartment 12 simpler and easier to implement.

[0036] This utility model also provides a wine bottle, which includes a bottle body and a bottle cap structure. The bottle cap structure is a bottle cap structure with storage function as described above. The upper end of the bottle body is a bottle neck 13, and the inner cap 6 is fixedly connected to the bottle neck 13.

[0037] In this embodiment, the bottle structure also includes an outer cap 2 and an outer cap fastener 1. The outer cap 2 and the outer cap fastener 1 are weakly connected. The outer cap fastener 1 is fixedly sleeved on the outside of the neck 13. The outer cap 2 and the top cap 4 are fixedly connected. The height of the outer cap fastener 1 is adapted to the storage space of the storage compartment 12, and the outer cap fastener 1 is configured to be non-transparent.

[0038] The outer cover fastener 1 is fixedly sleeved on the outside of the bottleneck 13. In this embodiment, it is achieved by a buckle 15. Any conventional implementation method is acceptable and will not be described in detail here.

[0039] The outer cover 2 and the top cover 4 are fixedly connected. In this embodiment, the outer cover 2 has a vertical thread inside, which fits tightly against the top cover 4, so that the top cover 4 can be rotated when it is opened.

[0040] The outer cap fastener 1 serves two purposes: firstly, it acts as an anti-counterfeiting measure, allowing the identification of whether the bottle cap has been opened; secondly, it can also cover the storage compartment 12, preventing any potential sediment from causing visual discomfort to consumers.

[0041] The weak connection mentioned refers to the limited connections in existing technologies such as aluminum caps and opening / closing points of plastic caps. For example... Figure 1 As shown, when the outer cover 2 rotates relative to the outer cover fixing part 1, the weak connection between them is damaged, and the opening part 3 will be twisted off.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
