Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figures 1 to 5This application provides a controllable flow bottle cap, including an upper cap 1 and a lower cap 2. The lower cap 2 is located below the upper cap 1, and the upper cap 1 and the lower cap 2 are detachably connected. A liquid outlet 21 is provided on the inner side of the lower cap 2, and the front end of the liquid outlet 21 is smaller than the rear end. A pull ring 31 is provided at the liquid outlet 21, and a sealing sheet 3 is provided on the end face of the lower cap 2 facing the pull ring 31. The sealing sheet 3 is used to close the liquid outlet 21. The pull ring 31 is connected to the sealing sheet 3 near the front end of the liquid outlet 21, and the other end of the pull ring 31 is a free end so that the user can pull the pull ring 31 to separate the sealing sheet 3 from the liquid outlet 21. The sealing sheet 3 has at least one folded groove 32. The folded groove 32 divides the sealing sheet 3 into flow control zones distributed along its tearing direction. When the outlet 21 is open, the sealing sheet 3 can be torn open to the corresponding folded groove 32 or completely torn open, depending on the flow rate requirements. At this time, part / all of the sealing sheet 3 is separated from the outlet 21, and the outlet 21 is partially / fully open. By controlling the effective outlet area of ​​the outlet 21, the liquid flow rate can be controlled. For example, when there is a large amount of liquid in the container, the outlet 21 can be partially opened, allowing the liquid to be poured out with a smaller outlet area, thereby controlling the outflow rate and effectively reducing the difficulty in controlling the pouring volume when there is a large amount of liquid in the container. When there is a small amount of liquid in the container, the outlet 21 can be fully opened, allowing the liquid to be poured out with a larger outlet area, thereby controlling the outflow rate and improving the liquid extraction efficiency when the flow rate in the container is low.

[0028] By setting the folding groove 32, the sealing sheet 3 can be torn open in multiple stages. The torn part of the sealing sheet 3 can be folded along the folding groove 32 without affecting the normal liquid extraction of the liquid outlet 21. The structure is simple and facilitates flow control according to the liquid extraction needs.

[0029] Reference Figures 2 to 5 Furthermore, a retaining ring 23 is provided on the end face of the lower cover 2 facing the upper cover 1. The outer diameter of the retaining ring 23 matches the inner diameter of the upper cover 1. The retaining ring 23 is provided with an external thread 231, and the inner wall of the upper cover 1 is provided with an internal thread 11. The internal thread 11 and the external thread 231 are threadedly connected to achieve the connection and fixation between the upper cover 1 and the lower cover 2. Preferably, the lower cover 2 and the retaining ring 23 are integrally formed for ease of manufacturing. In this embodiment, the outer periphery of the upper cover 1 is provided with anti-slip texture 12 to reduce the difficulty for the user to unscrew the upper cover 1.

[0030] Furthermore, a slot 232 is provided on the side of the retaining ring 23 near the rear end of the outlet 21, and the pull ring 31 can be engaged with the slot 232. When the outlet 21 is in a partially open state, the pull ring 31 can be engaged with the slot 232 and hung on the retaining ring 23. With this configuration, it is not necessary to manually pull the pull ring 31 to keep the outlet 21 in a partially open state when dispensing liquid, which is convenient for use.

[0031] Reference Figure 2 The sealing sheet 3 has at least one folding groove 32. In this embodiment, the sealing sheet 3 has one folding groove 32, which divides the sealing sheet 3 into a first flow control area 33 and a second flow control area 34. The area of ​​the second flow control area 34 is larger than that of the first flow control area 33. One end of the pull ring 31 is connected to the first flow control area 33. In use, the pull ring 31 is pulled to tear the sealing sheet 3 open to the folding groove 32. At this time, the first flow control area is separated from the lower cover 2, and the effective liquid outlet area of ​​the liquid outlet 21 is the area of ​​the first flow control area 33. Then, the pull ring 31 is hung in the slot 232 of the retaining ring 23 to extract the liquid. When the second flow control area 34 is separated from the lower cover 2, the effective liquid outlet area of ​​the liquid outlet 21 is the area of ​​the first flow control area and the area of ​​the second flow control area. That is, the liquid outlet 21 is in a fully open state at this time. In other embodiments, the number of folded grooves 32 can be set according to actual needs, that is, the number of folded grooves 32 can also be two, three or more; the position of the folded grooves 32 can also be set as needed, dividing the sealing sheet 3 into flow control areas of different sizes, so that each tear to different folded grooves 32 can increase the area of ​​different sizes of flow control areas. The setting of the number and position of the folded grooves 32 is not limited here.

[0032] Furthermore, in this embodiment, the liquid outlet 21 has a gourd-shaped structure with a small front end and a large rear end, and the sealing plate 3 is also configured to match the gourd-shaped liquid outlet 21. Preferably, in this structure, the folding groove 32 is provided at the connection between the front end and the rear end of the sealing plate 3. In other embodiments, the liquid outlet 21 may also be configured to have a structure that gradually increases in size from the front end to the rear end of the lower cover 2, etc., and is not limited to this specific embodiment.

[0033] The pull ring 31 is connected to the sealing sheet 3 near the front end of the outlet 21. The other end of the pull ring 31 is a free end. Specifically, the pull ring 31 is provided with a connecting rib 311, and the lower end of the connecting rib 311 is fixedly connected to the front end of the sealing sheet 3. Preferably, the pull ring 31, the connecting rib 311, and the sealing sheet 3 are integrally formed. The connecting rib 311 connects the sealing sheet 3 and the pull ring 31, which helps to ensure the connection strength between the pull ring 31 and the sealing sheet 3. The integral forming design also effectively reduces the possibility of breakage at the connection point.

[0034] Furthermore, the connection between the sealing sheet 3 and the lower cover 2 has a tear groove 22, specifically, the tear groove 22 is arranged around the sealing sheet 3. By setting the tear groove 22, while ensuring the sealing effect at the connection between the sealing sheet 3 and the lower cover 2, the thickness at the connection between the two is reduced, which can reduce the connection strength between the sealing sheet 3 and the lower cover 2, making it easier for users to tear open the sealing sheet 3, facilitating user use, and further reducing the possibility of the pull ring 31 and the sealing sheet 3 breaking.

[0035] Based on the controllable flow bottle cap with the above structure, this application also provides:

[0036] Reference Figure 1 A container includes a controllable flow cap with the structure described above, and a bottle body 4 having a bottle opening 41. The controllable flow cap is detachably connected to the bottle opening 41 to seal the bottle body 4, and liquid is contained within the bottle body 4.

[0037] Furthermore, a fixing ring 411 is provided around the outer periphery of the bottle mouth 41, and a buckle 24 is provided inside the lower cover 2 on the side away from the upper cover 1. The buckle 24 is engaged with the fixing ring 411 to achieve the connection and fixation of the controllable flow bottle cap and the bottle body 4.

[0038] During assembly, the bottle neck 41 is first pressed into the lower cover 2, so that the retaining ring 411 is connected and fixed with the buckle 24; then the internal thread 11 on the upper cover 1 is threadedly connected with the external thread 231 on the lower cover 2, thus assembling the entire container.

[0039] When using, the sealing sheet 3 should be torn open to different degrees depending on the amount of liquid in the container in order to control the liquid flow rate.
