Description

Technical Field

[0001] This invention relates to the field of bottle cap technology, and in particular to a volume control liquid bottle cap and its container. Background Technology

[0002] Small-volume liquids are commonly packaged in glass bottles, with the cap used to seal the bottle opening. The cap described in this invention can be used for packaging traditional Chinese liquid condiments such as soy sauce, vinegar, and wine, which require automatic volume control for multiple dispensing, and can also be used for packaging other liquids requiring automatic volume control for multiple dispensing.

[0003] Most existing liquid condiment bottle caps are flip-top type, and this type of cap has the following structural shortcomings:

[0004] In daily life, people usually take small amounts of bottled liquids multiple times. When pouring the liquid, they may accidentally pour out a large amount. If a bottle that is not tightly sealed is knocked over, the entire bottle of liquid will be spilled.

[0005] When pouring liquid, it is easy to spill, flowing outside the bottle or remaining on the outside of the cap. The residual liquid is exposed to the air, causing dirt and waste on the bottle surface. Subsequent pours are easily contaminated by the dirt formed at the bottle opening. If it is a condiment that is to be eaten directly, it will affect food safety.

[0006] When a flip-top bottle cap is closed tightly, the inherent characteristics of the locking mechanism inevitably cause a momentary closing process. The air inside the cap is compressed to form an airflow, and the collision between the two contact surfaces of the cap edge and the sleeve causes liquid residue on the edge of the cap to splash, contaminating hands and the environment. Utility Model Content

[0007] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a liquid control bottle cap and its container to achieve automatic volume control when pouring liquid and to stop the liquid from flowing out after a limited amount of liquid has been poured out; it also solves the problems of liquid easily flowing (leaking) when pouring liquid and liquid splashing when the cap is closed, which contaminates the bottle neck, the outer wall of the bottle, hands and the environment.

[0008] Technical solution

[0009] A volume control liquid bottle cap includes a volume control component inserted into a container and an upper body connected to the bottle opening of the container. The volume control component is connected to the upper body and includes a sleeve and a double conduit assembly disposed within the sleeve.

[0010] The dual-conduit assembly includes a liquid outlet channel, a gas and reflux liquid outlet channel, and a sealing plate. One end of the liquid outlet channel is located in the liquid storage tank, and the other end is connected to the upper body. The upper end of the gas and reflux liquid outlet channel is connected to the upper body.

[0011] The upper side of the casing is provided with a liquid flow channel and an air flow channel, with the liquid flow channel located above the air flow channel; the upper part of the casing is provided with a volume control chamber and the lower part with a liquid storage chamber. The liquid enters the volume control chamber and the liquid storage chamber through the liquid flow channel and is then output through the liquid outlet pipeline.

[0012] The liquid outlet channel is connected to a slanted flow-reducing inlet at the upper end and a slit funnel at the lower end. The lower edge of the slit funnel is in close contact with the inner wall of the sleeve, and the tip of the slanted flow-reducing inlet is located on the opposite side of the notch of the slit funnel.

[0013] The notch of the truncated funnel is located on the same side as the gas and reflux liquid channel, liquid channel, and airflow channel.

[0014] The liquid flow channel is located above the air flow channel, and the axes of the two are coplanar.

[0015] The gas and reflux liquid channels are open at both ends, and the gas and reflux liquid channels pass over the liquid flow channel and the air flow channel. The lower opening of the gas and reflux liquid channels is located below the lower edge of the air flow channel and above the upper edge of the notch of the slit funnel. The upper opening of the gas and reflux liquid channels is located above the sealing plate.

[0016] The upper body includes a sealing plate, which is located above the dual conduit assembly and above the liquid outlet channel, gas channel, and return flow channel. The oblique-cut flow reduction port is located above the sealing plate.

[0017] The upper body also includes an anti-theft cover, a sleeve, a first sealing assembly, a second sealing assembly, and a third sealing assembly;

[0018] The first sealing assembly includes a central inner plug and a liquid outlet mating surface. The central inner plug is located at the center of the top of the anti-theft cover, and the liquid outlet mating surface is located on the inner side of the top of the liquid outlet channel.

[0019] The second sealing assembly includes a middle ring inner plug and a mating surface. The middle ring inner plug is located between the upper inner side of the anti-theft cover and the outer side of the central inner plug, and the mating surface is located on the inner side of the sealing plate.

[0020] The third sealing assembly includes the outer wall of the sealing plate and the inner wall of the upper end of the sleeve for sealing.

[0021] The inner plug of the bottle mouth is fixedly set in the middle of the sleeve. The inner plug of the bottle mouth has openings at both ends. The upper opening of the inner plug of the bottle mouth is connected to the sleeve, and the lower opening of the inner plug of the bottle mouth is connected to the upper opening of the sleeve.

[0022] The liquid flow channel and the air flow channel are configured as liquid flow holes and air flow holes. The liquid enters the volume control chamber and the storage chamber through the liquid flow holes, and then is output through the liquid outlet pipeline.

[0023] The liquid flow channel and the air flow channel are configured as a hole with a large area at one end and a small area at the other end, with a cross-section in the shape of a gourd. The liquid enters the volume control chamber and the storage chamber through the liquid flow channel, and then is output through the liquid outlet pipeline.

[0024] The sleeve thread is located on the upper part of the outer wall of the sleeve, and the anti-theft cover thread is located on the upper inner wall of the anti-theft cover. The anti-theft cover and the sleeve are connected by the engagement of the thread pair.

[0025] A container includes a volume control liquid bottle cap and a bottle body, wherein the volume control liquid bottle cap is snapped onto the bottle opening of the bottle body, and an inner plug is pressed against the inner wall of the bottle opening.

[0026] Beneficial effects

[0027] By designing a sleeve to surround the liquid outlet channel, the liquid inside the bottle is prevented from flowing directly out of the bottle through the outlet channel. The sleeve also incorporates liquid flow channels and airflow channels on its sides, a volume control chamber at the top, a storage chamber at the bottom, and a funnel notch connecting the volume control chamber and the storage chamber. Furthermore, it connects the volume control chamber to the outside of the bottle for gas and reflux channels. Additionally, it includes an outlet channel and a slit-edge funnel. These mechanisms work together to achieve controlled liquid dispensing. Simultaneously, the liquid needs to be inverted at a large angle to flow out through the angled, reduced-flow nozzle, effectively preventing spillage (liquid dripping) and reducing contamination.

[0028] By designing a sleeve to surround the outlet channel, the liquid inside the bottle is prevented from flowing directly out of the bottle. During the first bottle inversion, a liquid flow channel on the side of the sleeve allows the liquid inside the bottle to flow into the volume control chamber channel, and an airflow channel allows gas from the volume control chamber to flow into the bottle. When the bottle is upright, the liquid in the volume control chamber flows into the storage chamber through the notch of the truncated funnel. The pressure balance required by the volume control chamber is achieved through the gas and reflux channels and the notch of the truncated funnel. During the second bottle inversion, the liquid in the storage chamber is collected through the truncated funnel and flows out of the bottle through the outlet channel. Simultaneously, the gas and reflux channels provide the necessary pressure balance for the liquid in the storage chamber to flow out of the bottle. During the second bottle inversion, the liquid flowing out of the bottle and the liquid flowing into the volume control chamber occur simultaneously. From the second inversion and uprighting of the bottle, this process is repeated, with the entire bottle of liquid flowing out in multiple stages until all the liquid in the bottle is drained.

[0029] By designing a threaded connection, liquid residue on the bottle cap edge will not splash; the outer edges of the two inner plugs inside the anti-theft cap are tightly pressed against the inner walls of the corresponding parts of the main body, the outer wall of the sealing plate and the inner wall of the upper end of the sleeve are tightly pressed against each other, and the inner plug of the bottle mouth is tightly pressed against the inner wall of the bottle mouth, thus achieving a seal and preventing liquid leakage when the liquid bottle is tilted.
