Description

Technical Field

[0001] The utility model relates to the field of liquid packaging, in particular to a novel valve type laundry liquid pouring cover. Background Art

[0002] Existing laundry detergent bottle caps have diverse structural designs, typically offering sealing, leak prevention, dosage control, and misuse prevention features to meet diverse user needs. The most common design is a conventional screw-on cap, which seals by rotating the cap. However, this makes it difficult to precisely control the flow rate during pouring, which can easily lead to spillage or waste. To improve dosage control, some designs feature caps shaped like measuring cups with graduated markings, allowing users to directly measure the amount of laundry detergent to be used. However, this often requires cleaning or wiping after use. Other caps feature push-type valves, allowing users to pour the detergent by pressing or squeezing the bottle. This design offers more flexible flow control and is easy for one-handed operation, but it is more complex and more expensive. Furthermore, leak-proof flip-top designs feature a small hole cover on the top of the cap to control the amount dispensed and prevent leakage when placed sideways or upside down. To enhance safety, some designs incorporate childproof locks on laundry detergent bottle caps, requiring a push and twist mechanism to open, reducing the risk of accidental contact by children.

[0003] However, no matter which laundry detergent bottle cap structure is used, there are still some shortcomings in actual use. Although the ordinary screw-on cap structure has good sealing performance, it needs to be rotated to open and close each time it is used, which is cumbersome to operate, and the flow rate is difficult to control when pouring, which can easily cause waste and even dirty the bottle mouth. In addition, although the measuring cup bottle cap can facilitate users to control the amount of use, it is troublesome to clean and easily leaves residual laundry detergent, resulting in an inconvenient user experience. The push-type valve design makes one-handed operation more convenient, but due to its complex structure and high cost, the pressing device may fail after long-term use, resulting in a decrease in sealing or the risk of leakage. Although the leak-proof flip-top design solves the problems of flow and leakage, it may cause liquid to remain at the bottle mouth when the bottle is inverted for use, and then cause liquid dripping when it is turned over. In addition, some child safety lock designs are too complicated, which not only plays a safety role for children, but sometimes also increases the difficulty for adults to open, especially for users with weak hand strength.

[0004] Therefore, it is necessary to solve the above problems to improve user experience and meet user needs. Utility Model Content

[0005] The purpose of the utility model is to provide a novel valve type laundry detergent pouring cover which can more conveniently pour out laundry detergent and freely control the pouring amount without having to repeatedly open the cover.

[0006] In order to achieve the above-mentioned object, the utility model adopts the following scheme: a novel valve-type laundry detergent pouring cover, comprising: a cover body, which can be screwed on the bottle mouth of the laundry detergent;

[0008] a communication hole penetrating the top wall of the cover body and communicating with the hollow valve cavity;

[0009] a pressing portion provided at one end of the valve body and capable of covering the opening of one end of the hollow valve cavity;

[0010] a valve plug movably provided at the other end of the valve body away from the pressing portion and used to close or open the opening of the hollow valve cavity at the end of the valve plug;

[0011] a valve plug rod connected to the valve plug and used to connect the valve plug and the pressing portion, so that the valve plug moves downward to open the opening of the hollow valve cavity at the end of the valve plug by pressing the pressing portion downward;

[0012] a guide rail provided on the inner wall of the hollow valve cavity in the axial direction of the hollow valve cavity;

[0013] a guide ring sleeved on the valve plug rod and capable of moving up and down along the valve plug rod and sliding along the guide rail.

[0014] Compared with the traditional screw cap, the user only needs to press to pour out the laundry detergent when using, which saves the cumbersome steps of repeatedly opening and closing, significantly improves the convenience, and can freely control the flow through the design of the valve plug, avoids the problems of overflow and waste, and improves the accuracy of the amount. In addition, the valve plug structure of the design prevents liquid leakage when not in use, maintains environmental cleanliness, and reduces the risk of misuse by children through the pressing mechanism of the valve, enhancing safety. In addition, compared with the troublesome measuring cup type bottle cap, this design reduces liquid residue after use, reducing cleaning difficulty. It is superior in user experience, flow control and safety, and can better meet the needs of users.

[0015] As a preferred embodiment of the utility model, the guide rails are symmetrically arranged on the circumferential inner wall of the hollow valve cavity, the circumferential outer wall of the guide ring is respectively provided with a connecting frame extending towards the corresponding guide rail, and the end of the connecting frame is respectively provided with a guide groove capable of being slidably clamped on the guide rail. The guide rails are symmetrically arranged on the inner wall of the hollow valve cavity, which helps the stable sliding of the guide ring and the valve plug rod, reduces friction, ensures the flexibility and durability of the valve plug. The guide groove design on the connecting frame makes the guide ring move more smoothly, thereby improving the opening and closing efficiency of the valve and prolonging the service life.

[0016] As a further aspect of the present application, a water flow blocking part is arranged on the outer wall of the guide ring on the side of the communication opening, and the flow of liquid through the hollow valve cavity and the opening at one end of the valve plug can be controlled by changing the size of the water flow blocking part. By using water flow blocking parts of different sizes, users can adjust the flow of liquid through the hollow valve cavity according to their needs, achieving more precise control of the amount. This design makes it more flexible to pour laundry detergent, and can meet the needs of different use scenarios, helping to reduce waste.

[0017] As a preferred aspect of the present application, an annular mounting groove is arranged at the opening of the hollow valve cavity where the pressing part is located, the pressing part is made of flexible rubber in a bowl shape, the opening circumference of the pressing part is embedded in the annular mounting groove through interference fit, and one end of the valve plug rod is detachably connected to the central inner wall of the pressing part. The flexible rubber material of the pressing part, combined with the design of the annular mounting groove, can effectively improve the comfort and sealing performance of the pressing part, enhancing user experience. In addition, this structure is convenient to replace and maintain, improving the convenience of product use.

[0018] As a preferred aspect of the present application, a connecting column extending towards the valve plug direction is arranged on the central inner wall of the pressing part, the connecting column end is provided with a mounting hole with an opening, an annular clamping table is arranged on the circumferential inner wall of the connecting pipe, and the top of the valve plug rod is inserted into the mounting hole and provided at the end with an annular clamping groove capable of being clamped together with the annular clamping table. The detachable connection design of the connecting column and the valve plug rod makes it more convenient to maintain and replace the valve plug, and through the cooperation of the annular clamping table, the firmness and stability of the connection are ensured, reducing the risk of failure due to wear during use.

[0019] As a preferred aspect of the present application, a convex ring is arranged on the circumferential outer wall of the middle segment of the valve plug rod, and an annular groove capable of clamping the convex ring is arranged on the circumferential inner wall of the guide ring. The cooperation design of the convex ring and the annular groove in this scheme makes it easier to reduce the difficulty of assembly.

[0020] As a preferred aspect of the present application, the valve plug is trumpet-shaped and integrally formed with the valve plug rod, a first matching slope is arranged around the circumference of the valve plug near the bottom end, a second matching slope is arranged on the inner wall of the hollow valve cavity opening at one end of the valve plug, and the second matching slope and the first matching slope are in interference fit. The trumpet-shaped design of the valve plug cooperates with the slope structure to effectively improve the sealing performance of the valve plug, ensuring that the flow outlet is completely closed when closed, and preventing laundry detergent from leaking. The slope design also makes the valve plug easier to move when opened, enhancing the smoothness of use.

[0021] As a further feature of this invention, symmetrical auxiliary operating wings are provided on the outer wall of the valve body to provide additional finger support when pouring laundry detergent, increasing operational stability. This design makes use easier, especially when greater force is required, and effectively reduces hand fatigue.

[0022] As a preferred solution of the present invention, the circumferential wall of the inner cavity of the lid is provided with an internal thread that matches the external thread on the bottle mouth of the laundry detergent, ensuring a tight fit between the lid and the bottle mouth, enhancing the sealing and reducing the risk of leakage. This design can also simplify the installation process.

[0023] As a further feature of the present invention, positioning bumps are provided on the circumferential wall of the lid cavity, which engage with pre-installed stops on the bottle opening to limit the orientation of the hollow valve cavity opening at one end of the valve plug. These positioning bumps ensure the valve plug remains in the correct orientation. When the bottle is placed flat, the liquid detergent outlet, where the valve plug is located, faces downward. This makes it easier for users to access liquid detergent during use, avoiding the inconvenience of tilting or skewing the bottle.

[0024] In summary, the beneficial effects of the present invention compared to the prior art are as follows: by adding a faucet-like liquid outlet structure to the cover body, the present invention allows users to pour out laundry detergent with a simple press operation, eliminating the tedious steps of repeatedly opening and closing the cover, and significantly improving convenience and efficiency of use. In terms of flow control, the design of the valve plug combined with the water flow blocking part enables users to flexibly adjust the flow of liquid to meet the needs of different usage scenarios, effectively avoiding the problems of uneven flow and easy overflow of traditional bottle caps when pouring. At the same time, the design of the guide rail and the connecting frame ensures the stable sliding of the valve plug, reduces friction, improves durability, and enhances the overall user experience.

[0025] Furthermore, the valve plug's trumpet-shaped structure and beveled surface significantly enhance its sealing performance, effectively preventing detergent leaks and resolving a common leak-proofing issue with traditional bottle caps. The flexible rubber pressure element not only enhances pressing comfort but also simplifies cleaning, making it even more convenient to use. For child safety, the valve design effectively reduces the risk of misuse. The positioning bump ensures that the valve plug points vertically downward when the bottle is laid flat, making it easy for users to access the detergent and reducing the possibility of tilting and dripping.

[0026] Overall, the present invention not only effectively solves the shortcomings of existing bottle cap designs by improving flow control, enhancing sealing, and enhancing safety and convenience, but also significantly improves the user experience and meets the modern consumer's demand for functionality and convenience.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Figures 1 to 8The illustrated novel valve-type laundry liquid pouring cap includes a cap body 1 that can be screwed onto the mouth of a laundry liquid bottle. The circumferential wall of the inner cavity of the cap body 1 is provided with internal threads 12 that mate with the external threads on the mouth of the laundry liquid bottle. A communication port 11 extends through the top wall of the cap body 1. A valve body 2 is connected to the outer surface of the top wall of the cap body 1. The valve body 2 includes a hollow valve cavity 3 with upper and lower openings. The communication port 11 communicates with the hollow valve cavity 3. A pressing portion 4 is provided at one end of the valve body 2, which can cover the opening of the hollow valve cavity 3. Specifically, an annular mounting groove 32 is provided at the opening of the hollow valve cavity 3 where the pressing portion 4 is located. The pressing portion 4 is made of a bowl-shaped flexible rubber, and the opening circumference of the pressing portion 4 is inserted into the annular mounting groove 32 through an interference fit. A valve plug 5 is provided at the other end of the valve body 2, away from the pressing portion 4. The valve plug 5 is movably mounted within the hollow valve cavity 3, used to close or open the opening of the hollow valve cavity 3 at the end where the valve plug 5 is located. A valve plug stem 51 is connected between the valve plug 5 and the pressing portion 4. A connecting post 41 is provided in the center of the inner wall of the pressing portion 4, extending toward the valve plug 5. The end of the connecting post 41 is provided with an assembly hole 42 with an opening. An annular retaining plate 43 is provided on the circumferential inner wall of the assembly hole 42. The top of the valve plug stem 51 is inserted into the assembly hole 42, and the end is provided with an annular retaining groove 52 that engages with the retaining plate 43. A guide rail 31 is provided on the inner wall of the hollow valve cavity 3 along the axial direction of the hollow valve cavity 3. A protruding ring 53 is provided on the outer circumferential wall of the middle section of the valve plug rod 51. A guide ring 6 is provided on the outer circumferential wall of the protruding ring 53. An annular groove 63 is provided on the inner circumferential wall of the guide ring 6, which can be engaged with the protruding ring 53, so that the guide ring 6 can move up and down with the valve plug rod 51 and slide along the guide rail 31. By pressing the pressing portion 4 downward, the pressing portion 4 is deformed and concave, thereby causing the valve plug 5 to move downward, thereby allowing the valve plug 5 to move outward from the opening of the hollow valve cavity 3 at one end of the valve plug 5, so that the opening of the hollow valve cavity 3 at the end of the valve plug 5 is fully connected with the communication port 11 and opened, thereby serving as an outflow port for the laundry liquid.

[0039] Specifically, if Figures 2 to 8 As shown, the guide rails 31 are symmetrically arranged on the circumferential inner wall of the hollow valve cavity 3, and the circumferential outer wall of the guide ring 6 is respectively provided with connecting brackets 61 extending toward the corresponding guide rails 31. The ends of the connecting brackets 61 are respectively provided with guide grooves 62 that can be slidably engaged with the guide rails 31. In order to enable users to flexibly adjust the flow rate of the liquid to meet the needs of different usage scenarios, the guide ring 6 is provided with a water flow blocking portion 7. The water flow blocking portion 7 is symmetrically arranged on the outer wall of the guide ring 6 on the side of the communication port 11. In this embodiment, the water flow blocking portion 7 is two opposing cross bars.

[0040] like Figure 7 and Figure 8FIGURE 7 shows another embodiment of a water flow barrier 7. As can be clearly seen from the figure, this embodiment is essentially the same as the previous embodiment, differing only in the horizontal area of ​​the crossbar. By varying the size of the water flow barrier 7, the flow rate of liquid flowing through the hollow valve cavity 3 and through the opening at the end where the valve plug 5 is located can be controlled. Because the water flow barrier 7 is located on one side of the communication port 11, when the guide ring 6 moves downward with the valve plug rod 51, the water flow barrier 7 simultaneously enters the hollow valve cavity 3 below the communication port 11, blocking a portion of the hollow valve cavity 3. As a result, the amount of laundry liquid flowing out through the opening at the end where the valve plug 5 is located is reduced.

[0041] In addition, in order to effectively improve the sealing performance of the valve plug 5, it is ensured that the outlet can be completely closed when the opening of the hollow valve cavity 3 at one end of the valve plug 5 is closed to avoid leakage of the laundry liquid. Figures 2 to 6 As shown in the figure, it can be clearly seen that the valve plug 5 is trumpet-shaped, and the top of the valve plug 5 is integrally formed with the valve plug rod 51. A first matching bevel 54 is provided around the periphery of the valve plug 5 near the bottom end, and a second matching bevel 33 is provided on the inner wall of the opening of the hollow valve cavity 3 at one end where the valve plug 5 is located. When the valve plug 5 is located in the hollow valve cavity 3 at one end, the second matching bevel 33 and the first matching bevel 54 are interference fit. In this way, the entire valve plug 5 can completely block the opening of the hollow valve cavity 3 at one end to prevent the laundry detergent from leaking out.

[0042] It should be noted that in order to facilitate the operator to press the pressing part 4 downward, mutually symmetrical auxiliary operating wings 21 are provided on the outer wall of the valve body 2. When it is necessary to press the pressing part 4 downward, the index finger and the middle finger respectively hold the bottom surface of the auxiliary operating wings 21 upward, and the thumb presses the bowl-shaped pressing part 4 to easily open the opening of the hollow valve cavity 3 at one end where the valve plug 5 is located.

[0043] In addition, if Figure 6 As shown in the figure, when the laundry detergent bottle is placed flat, the laundry detergent outlet where the valve plug 5 is located must face downward, not tilted or skewed. This allows for easier access to the laundry detergent during use. Positioning bumps 13 are provided on the circumferential wall of the inner cavity of the lid 1, which engage with pre-installed stops on the laundry detergent bottle opening to limit the direction of the opening of the hollow valve cavity 3 at the end where the valve plug 5 is located. This helps prevent the inconvenience caused by tilting or skewing the valve body 2 and reduces the risk of liquid residue on the valve body 2.

[0044] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
