FIELD OF THE DISCLOSURE
The present disclosure relates to the technical field of bottles, in particular to a valve structure, a bottle cap, and a bottle.
BACKGROUND
Bottles are commonly used as containers in daily life, such as common water bottles. In some water bottles (such as sports water bottles), a soft rubber valve is arranged at a bottle cap. The soft rubber is pressed and deformed by squeezing the water bottle body, thus opening the valve, thus water can be squeezed out of the water bottle body. After the water bottle body is released, the water bottle body is restored to an original state without being pressed, and the soft rubber valve is restored to an original state to close the valve, thus preventing the water in the water bottle body from pouring out.
An existing valve structure generally consists of a rigid press cover and a soft nozzle. The nozzle is connected to a bottle cap through the press cover. In the process of the press cover tightly pressing the nozzle, the press cover needs to be threaded with the bottle cap, so as to encapsulate the nozzle as a whole on the bottle cap to achieve a firm fixed connection. During the use of the bottle cap, it is inconvenient to disassemble and clean the valve structure.
Therefore, the prior art still needs to be improved and developed.

DETAILED DESCRIPTION
The present disclosure provides a valve structure, a bottle cap, and a bottle. In order to make the purposes, the technical schemes, and the beneficial effects of the present disclosure clearer and more explicit, the present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.
The valve structure of existing water bottles is difficult to disassemble, causing difficulty in cleaning; the gasket and nozzle of the existing water bottles are both manufactured separately, thus not only the gasket and the nozzle are easily detached due to squeezing, but also the gasket and the nozzle need manual or mechanical assembly after being manufactured separately, which increases production processes, reduces production efficiency, and increases production cost. Therefore, the present disclosure solves the above problems by the following embodiments. In addition, the existing valve structure only has the function of closing and opening the bottle opening, and does not have the functions of blocking ice or filtering, so that during the process of drinking ice water, large pieces of ice residue (ice cubes) are squeezed out through the existing valve structure, causing problems such as poor user experience. In order to solve the above problems, the present disclosure provides the following embodiments.
Embodiment 1
As shown in FIGS. 1 and 6, the present embodiment provides a valve structure 10 arranged on a cap body 20, and the cap body 20 is detachably arranged on a bottle body to form a bottle. As shown in FIGS. 5 and 6, the cap body 20 is arranged with a water outlet 21. When the bottle is in use, liquid can flow out of the water outlet 21. To facilitate structural description, a direction of the liquid flowing out of the water outlet 21 is set as upward; a central axis of the bottle is set as a center, a direction toward the center is inward, and a direction away from the center is outward. As shown in FIGS. 1, 2 and 6, the valve structure 10 mainly includes: a rigid connecting portion 100, a flexible valve body 200, and a connecting part 300. The rigid connecting portion 100 has a liquid flow channel 101 axially penetrating through the rigid connecting portion 100. The flexible valve body 200 is located inside the liquid flow channel 101 and connected to the rigid connecting portion 100. A valve opening 220 is arranged at a middle of the flexible valve body 200. The flexible valve body 200 deforms under pressure to open the valve opening 220. The rigid connecting portion 100 extends along an axial direction for a predetermined length, so as to make the liquid flow channel 101 completely cover the flexible valve body 200, so that during a process of the liquid being squeezed out when the bottle is in use, deformation of the flexible valve body 200 is limited by an inner wall of the rigid connecting portion 100, so as to make the valve opening 220 located at the middle of the flexible valve body 200 deform to open, thereby enhancing stability of the valve structure 10 during use. The connecting part 300 is arranged on an outer wall of the rigid connecting portion 100. The rigid connecting portion 100 is detachably connected to an inner wall of the water outlet 21 of the cap body 20 by the connecting part 300. For example, the rigid connecting portion 100 is detachably connected to a connection position 26 of the inner wall of the water outlet 21. The connecting part 300 is integrally formed with the rigid connecting portion 100, and by applying force on the rigid connecting portion 100, the connecting part 300 can be driven into the connection position 26 of cap body 20, thereby assembling the entire valve structure 10 to the rigid connecting portion 100.
As shown in FIGS. 2, 3, and 6, a usage principle and effect of the valve structure 10 in the embodiment are: the rigid connecting portion 100 serves as a bracket to fix the flexible valve body 200 inside the bottle body and to make the flexible valve body 200 cover the water outlet 21. The valve opening 220 is arranged at the middle of the flexible valve body 200, and when the flexible valve body 200 is not under pressure, inner walls of the valve opening 220 abut against each other, so that the valve opening 220 is closed. When the flexible valve is squeezed by the liquid in the bottle, the flexible valve is deformed due to force, so that the inner walls of the valve opening 220 are squeezed open, causing the valve structure 10 to open and allow the liquid to flow out. Therefore, by squeezing the bottle body, the liquid in the bottle is squeezed, and the flexible valve body 200 is deformed by the squeezing of the liquid in the bottle, so as to open the valve opening 220. The flexible valve body 200 is stably fixed inside the bottle body by the rigid connecting portion 100 and covers the water outlet 21. During use, the liquid in the bottle is pressurized by squeezing the water bottle, thereby the flexible valve body 200 is squeezed, causing the flexible valve body 200 to be deformed under pressure, so as to cause the valve opening 220 to deform and then open, and the water outlet 21 is opened, thereby the liquid is squeezed out of the water bottle. After the water bottle is released by a hand, the water bottle is not pressurized and returns to its original state, the flexible valve body 200 returns to its original state to make the valve structure to shrink and close, and the water outlet 21 is closed, thereby preventing the liquid in the water bottle from pouring out. By arranging the flexible valve body 200 inside the rigid connecting portion 100 and being fixedly connected to the rigid connecting portion 100, the liquid in the liquid flow channel 101 of the rigid connecting portion 100 can be squeezed out through the valve opening 220 of the flexible valve body 200. When the valve structure 10 is assembled and disassembled, by operating the rigid connecting portion 100, the flexible valve body 200 can be assembled and disassembled together with the rigid connecting portion 100. The connecting part 300 is arranged on the outer wall of the rigid connecting portion 100. The rigid connecting portion 100 is detachably connected to the connection position 26 on the inner wall of the water outlet 21 of the cap body 20 by the connecting part 300. Therefore, it is only necessary to remove the connecting part 300 when disassembling, the entire valve structure 10 can be taken out of the connection position 26. The valve structure is detachably connected, making it convenient to clean the valve structure 10 and then fix the valve structure into the cap body 20 for continue using, which enhances the practicality of the bottle.
As shown in FIGS. 1, 2, and 3, the rigid connecting portion 100 in the embodiment is made of a harder material, and is not deformed by the squeezing force of the bottle (the bottle is squeezed when water is outlet), thus, the rigid connecting portion 100 can be stably fixed at the water outlet 21. A material of the flexible valve body 200 is relatively soft and is easily deformed when squeezed. Optionally, the flexible valve body 200 and the rigid connecting portion 100 are integrally formed by injection molding to achieve a fixed connection between the flexible valve body 200 and the rigid connecting portion 100. By integrally forming the rigid connecting portion 100 and the flexible valve body 200, an integrated valve structure 10 is formed, so that the rigid connecting portion 100 and the flexible valve body 200 are more firmly fixed, and the rigid connecting portion 100 and the flexible valve body 200 will not be separated unless they are violently damaged, thereby preventing the bottle valve from falling off and failing during use. At the same time, the integrated structure is formed directly by injection molding, so that the assembly can be completed during the production process, and there is no need to assemble the rigid connecting portion 100 and the flexible valve body 200 additionally, thereby reducing the manual or mechanical assembly process of both the flexible valve body 200 and the rigid connecting part 100, and greatly improving production efficiency.
In an existing structure, a flexible valve body is usually clamped in a bottle cap. Improper assembly or vibration causes the flexible valve body to become loose easily. The flexible valve body is a small object, which causes safety hazards. In the embodiment, the flexible valve body 200 and the rigid connecting portion 100 are integrally formed to form an integrated valve structure, so that the flexible valve body 200 is arranged inside the rigid connecting portion 100, and the integrated valve structure is arranged inside the cap body 20, avoiding the problem that the flexible valve body 200 falls off from the cap body 20 due to improper assembly or vibration.
As shown in the embodiment of FIGS. 2 and 3, the flexible valve body 200 and the rigid connecting portion 100 are formed into an integrated valve by two-color injection molding at one time. In the embodiment, the rigid connecting portion 100 is made of thermoplastic material, and the flexible valve body 200 is made of thermoplastic elastomer (such as TPE, silicone, rubber, etc.). The two materials are injection molded at one time by two-color injection molding to form an integrated valve structure. The entire integrated valve structure has good bonding firmness, compared with a single-piece silicone valve structure in the prior art, the structural strength of the integrated valve structure is equivalent, and the single-piece silicone valve structure in the prior art requires additional auxiliary parts (gaskets) to fixedly cooperate with the bottle. However, the integrated valve structure in the embodiment is directly clamped with the bottle body, and has better connection stability.
As shown in FIGS. 2 and 3, a hardness of the flexible valve body 200 in the embodiment is Shore A 30-80 degree. The soft rubber with the hardness facilitates the valve opening 220 to be squeezed to open by the liquid in the bottle. The hardness of the rigid connecting portion 100 is Shore D 50-95 degree. The hardness of the hard rubber formed by the rigid connecting portion 100 is Shore D 50-95 degree (6 mm slice and less than 23° C.). When the bottle body is squeezed by the user, the hard rubber with the hardness is not easily deformed, thereby the flexible valve body 200 is firmly connected to the water outlet 21 of the bottle body. Optionally, the hardness of the flexible valve body 200 may also be Shore A more than 80 degree or Shore A less than 30 degree, but it is uncomfortable to use. Optionally, the rigid connecting portion 100 may adopt hard rubber with other hardness.
As shown in FIGS. 3 and 6, an upper end of the flexible valve body 200 in the embodiment is arranged with a flange 210, and the flange 210 covers an upper surface of the rigid connecting portion 100. Therefore, when the valve structure 10 is arranged into the cap body 20, the flange 210 of the flexible valve body 200 abuts against an inner wall of the connection position 26 on the cap body 20. Since the flange 210 is made of soft rubber, the flange 210 not only increases a contact area with the rigid connecting portion 100, thereby making the valve structure 10 firmer, but also serves as a sealing assembly to seal a connection position between the valve structure 10 and the cap body 20.
As shown in FIGS. 1, 3, and 4, the rigid connecting portion 100 in the embodiment includes a rigid outer tube 110 and an ice-stopping part 400. An axial length of the rigid outer tube 110 is relatively long. The connecting part 300 is arranged on an outer wall of the rigid outer tube 110 and is located at an upper end of the rigid outer tube 110. The rigid outer tube 110 is clamped in the connection position 26 on the cap body 20 by the connecting part 300 at the upper end. The liquid flow channel 101 penetrates through the rigid outer tube 110. The ice-stopping part 400 is detachably arranged at one end of the rigid outer tube 110 and covers the liquid flow channel 101. During cleaning the valve structure, the ice-stopping part 400 can be disassembled, thereby facilitating cleaning an inner surface of the rigid outer tube 110 and more thoroughly cleaning the valve structure. When the bottle is in use, the pressurized liquid is filtered by the ice-stopping part 400 and then enters the liquid flow channel 101, and then flows out of the valve opening 220. The ice-stopping part 400 is mainly used to filter solids in the liquid, such as ice residue, juice residue, etc. By providing the ice-stopping part 400, solid particles in the bottle can be filtered, so that the liquid flowing out of the valve opening 220 does not contain larger solid particles (ice cubes), thereby improving practicality.
Optionally, the ice-stopping part 400 can be integrally formed with the rigid outer tube 110, but it is not convenient for cleaning the inner wall of the rigid outer tube 110. The ice-stopping part 400 in the embodiment is detachably arranged, which facilitates the disassembly of the ice-stopping part from the rigid outer tube 110, so that during the cleaning process, it is convenient to clean the inner wall of the rigid outer tube 110, thus the valve structure 10 can be cleaned cleaner.
As shown in FIGS. 3, 4, and 5, the ice-stopping part 400 in the embodiment includes: a casing 410 and a filter part 420. The casing 410 is embedded inside the rigid outer tube 110, and an inner cavity of the sleeve 410 is connected to the liquid flow channel 101, allowing fluid to pass through. A snap piece 430 is arranged on an outer wall of the casing 410. The filter part 420 is arranged on the casing 410 and is used to prevent predetermined solid objects in the liquid from entering the liquid flow channel 101. Further, the filter part 420 is arranged in an inner cavity of a lower end of the casing 410, and the filter part 420 includes a plurality of filter holes 422. Each filter hole has a smaller size, which allows the liquid in the bottle to pass through and enter the liquid flow channel 101, while blocks larger solid particles (such as larger ice cubes) in the bottle. In order to make a flow rate of the liquid entering the liquid flow channel 101 more uniform, the filter hole 422 is fan-shaped, and the plurality of filter holes 422 is distributed in a circular array around the liquid flow channel 101. In the embodiment, the inner wall of the rigid outer tube 110 is arranged with a snap groove 120, and the snap piece 430 is connected inside the snap groove 120 to make the casing 410 connected to the rigid outer tube 110. By the cooperation of the snap piece 430 and the snap groove 120, the ice-stopping part 400 and the rigid connecting portion 100 can be quickly disassembled and quickly assembled, which facilitates the disassembly and assembly of the ice-stopping part 400 and the rigid connecting portion 100.
As shown in FIGS. 4 and 5, the snap piece 430 includes a snap boss 431, which protrudes from a surface of the outer wall of the casing 410. The snap boss 431 may be a circular boss, the circular boss protrudes radially from the outer wall of the casing 410 for a certain length (a small length). The snap groove 120 includes an axial groove 121 and a circumferential groove 122. The axial groove 121 is located at a lower end of an inner cavity of the casing 410 and is arranged in an up-and-down direction. One end of the axial groove 121 is connected to an upper end of the axial groove 121, and extends on the inner wall of the casing 410 for a predetermined length in an circumferential direction. When the ice-stopping part 400 is assembled with the rigid connecting portion 100, the snap boss 431 is aligned with the axial groove 121 and pushed into the axial groove 121, the snap boss 431 slides along the axial groove 121 to a top end of the axial groove 121, and then enters the circumferential groove 122 by rotating. The circumferential groove 122 limits an up-and-down direction of the snap boss 431, so that the ice-stopping part 400 and the rigid connecting portion 100 are snapped together. This structure facilitates quick disassembly of the ice-stopping part 400, has a simple structure, high cleaning efficiency, and good effect.
As shown in FIGS. 3 and 4, the filter part 420 in the embodiment includes a filter plate 421. The filter plate 421 is located at a lower end of the casing 410. A diameter of the filter plate 421 is larger than an outer diameter of the casing 410. The filter hole 422 is arranged at a middle position of the filter plate 421. An observation groove 423 is also arranged on the filter plate 421. The observation groove 423 penetrates through upper and lower surfaces of the filter plate 421 and is opposite to a position of the snap piece 430, so that the snap piece 430 can be seen through the observation groove 423. During assembly of the ice-stopping part 400, a user can see through the observation groove 423 whether the snap piece 430 is aligned with the axial groove 121. When disassembling, a user can see through the observation groove 423 whether the snap piece 430 rotates inside the axial groove 121 from the circumferential groove 122, so that the position of the snap piece 430 can be accurately observed to facilitate the assembly and disassembly of the ice-stopping part.
In the embodiment, two snap pieces 430 are arranged, and the two snap pieces 430 are symmetrically arranged. Correspondingly, two corresponding snap grooves 120 are arranged. The snap piece 430 arranged symmetrically can balance force and stabilize connection. Optionally, the snap piece 430 may also be arranged on an inner wall of the rigid outer tube 110, and the snap groove 120 is correspondingly arranged on a surface of an outer wall of the casing 410.
As shown in FIGS. 1, 3, and 4, the ice-stopping part 400 further includes a holding part 440, and the holding part 440 is arranged at a bottom of the casing 410. In a specific structure, the holding part 440 is arranged on a lower surface of the filter plate 421 and is located at an outer side of the filter hole 422. A user holds the ice-stopping part 400 by the holding part 440, thereby conveniently twisting the ice-stopping part 400, so that the ice-stopping part 400 can be disassembled from the rigid connecting portion 100 more quickly.
As shown in FIGS. 1, 3, and 4, the holding part 440 in the embodiment includes a plurality of holding bosses 441, such as two holding bosses 441, and the two holding bosses 441 are respectively located at two radial ends of the filter plate 421. Each filter hole 422 is located between the two holding bosses 441, and the holding boss 441 is bow-shaped or semicircular. Therefore, when rotating the ice-stopping part clockwise or counterclockwise, a user can apply force with one hand, making it more convenient to disassemble.
As shown in FIG. 5, the water outlet 21 of the cap body 20 includes a connection cavity 22, a conical cavity 23, a water-outlet cavity 24, and a hole opening 25 along the direction from bottom to top. An order of inner diameters from large to small is as follows: the connection cavity 22, the conical cavity 23, the water-outlet cavity 24, and the hole opening 25. A clamping groove is formed at a connection position between the conical cavity 23 and the water-outlet cavity 24. The clamping groove is located at an upper end of the conical cavity 23 and is concavely formed. The inner diameter of the conical cavity 23 gradually becomes smaller along the direction from bottom to top, so when the rigid connecting portion 100 moves upward by the connecting part 300, the rigid connecting portion 100 is gradually compressed and deformed by squeezing from a plastic piece, so that the connecting part 300 is embedded inside the clamping groove for fixation.
As shown in FIG. 6, an outer wall of the rigid outer tube 110 and an inner wall of the cap body 20 are spaced apart to form a liquid outlet space 130. The outer wall of the rigid outer tube 110 is arranged with a side hole 131, and the side hole 131 is configured to connect with both the liquid outlet space 130 and the liquid flow channel 101, allowing fluid to pass through. The side hole 131 can increase liquid flow capacity in the liquid flow channel 101, and the side hole 131 being arranged on the outer wall of the side surface of the rigid outer tube 110 can control the flow capacity from being too large. An inner diameter of a lower part of the conical cavity 23 gradually becomes larger, so that the liquid outlet space 130 is formed between the conical cavity 23 and the rigid outer tube 110, and the liquid outlet space 130 is connected to the internal liquid flow channel 101 by the side hole 131, allowing fluid to pass through. When liquid is squeezed out, if there are more and larger ice cubes in the liquid, the filter part 420 of the ice-stopping part 400 is easily blocked, and the liquid cannot flow out of the water outlet, resulting in difficulty in discharging the liquid. By arranging the side hole 131, the quantity of the liquid entering the liquid flow channel 101 can be increased. When the filter part 420 is blocked, the liquid still can enter the liquid flow channel 101 from the side surface by the liquid outlet space 130, thereby ensuring smooth liquid discharge of valve structure 10.
As shown in FIGS. 5 and 6, it should be noted that, due to the conical structure of the conical cavity 23, the liquid outlet space 130 becomes smaller as it goes upward. Therefore, a side groove is arranged at one side of the rigid outer tube 110 facing the connecting part 300. The liquid outlet space 130 at this position is small, and the liquid outlet space 130 can block larger ice residue, which plays a role in filtering the ice residue.
The side groove is configured as an elongated groove extending a predetermined length along a circumferential direction. By circumferentially arranging the side groove, the flow capacity can be increased, and at the same time, an inner wall of the conical cavity 23 can effectively block an outer side of the side groove, so as to realize a filtration function. In order to achieve radial liquid-discharge balance, two side grooves are arranged in the circumferential direction.
As shown in the embodiment of FIGS. 1, 5, and 6, one end of the rigid outer tube 110 deviating from the water outlet 21 is arranged with a holding stop plate 140, and the holding stop plate 140 and an inner wall of the cap body 20 are spaced apart. A recess 141 is arranged at an edge of the holding stop plate 140, and the recess 141 is connected to the liquid outlet space 130, allowing fluid to pass through. By arranging the recess 141, the edge of the holding stop plate 140 has a hand hold position, which facilitates a user to insert a finger into the recess 141 to hold the holding stop plate 140, and facilitates the rotation of the holding stop plate 140, thereby making it easier to disassembly the entire valve structure. Since the connecting part 300 and the connection position 26 form a squeezing fit, it is easier to pull out the entire valve structure 10 by holding the holding stop plate 140.
As shown in FIGS. 5 and 6, specifically, the holding stop plate 140 extends a predetermined length in a radial direction, and an outer diameter of the holding stop plate 140 is larger than an outer diameter of the rigid outer tube 110. A gap is formed between an outer edge of the holding stop plate 140 and an inner wall of the connection cavity 22, and an upper surface of the holding stop plate 140 and a top surface of the connection cavity 22 are spaced apart to form a side gap 150, so that the liquid can enter the liquid outlet space 130 from the side gap 150, and then enter the liquid flow channel 101 from the liquid outlet space 130 through the side hole 131. A size of the side gap 150 is smaller, which can block larger ice cubes in the liquid, thereby not only increasing the liquid capacity, but also filtering the larger ice cubes. Combining with a filtering effect of the conical liquid flow channel 101 on small ice cubes and ice crystals, the outflow liquid does not contain larger ice crystals. In addition, the side gap 150 increases a length of a flow path of the liquid and is blocked multiple times by the inner wall. Usually, the liquid easily changes its flow direction in the gap, while solids such as ice residue cannot easily change the flow direction. This also has a certain blocking effect on the solids, and can ensure that the liquid can flow out smoothly. In the embodiment, a gap distance between an upper surface of the holding stop plate 140 and a top surface of the connection cavity 22 may be 5-6 mm, which can provide a good ice-stopping effect.
As shown in FIGS. 1, 2, and 5, in addition, four recesses 141 are arranged in the embodiment, and the four recesses 141 are evenly distributed along a circumference of the holding stop plate 140. The recess 141 penetrates through the holding stop plate 140 in an up-and-down direction, so that during the liquid squeezing process, a part of liquid can directly enter the side gap 150 through a position of the recess 141, which allows the liquid to directly enter the side gap 150, thereby enhancing the flow capacity of the outflow liquid to a certain extent.
Therefore, the holding stop plate 140 in the embodiment not only functions to facilitate holding and disassembling the valve structure 10, but also cooperates with an inner wall of the cap body 20 to achieve a filtering function. The squeezed liquid directly enters the side gap 150 through the recess 141, and the holding stop plate 140 cooperates with the side hole 131 to increase the outflow liquid capacity.
In the embodiment, an outer edge of the holding stop plate 140 is flush with an outer edge of the filter plate 421, and the corresponding edge of the filter plate 421 is arranged with a recess 141. In this way, the entire valve structure 10 can be pulled out as a whole, and then the ice-stopping part 400 can be disassembled, which facilitates the disassembly and assembly of the valve structure 10.
Specifically, a diameter of an outermost edge of the rigid connecting portion is based on geometry of the cap. Further, the diameter of an outermost edge of the rigid connecting portion is not less than 31.75 mm. An outer dimension of the holding stop plate 140 in the embodiment is the largest, so that the diameter of the outermost edge of the holding stop plate 140 is not less than 31.75 mm. The valve structure of the size complies with size safety standards of small toys and eliminates hidden dangers of users accidentally swallowing small objects.
As shown in FIGS. 1, 5, and 6, the connecting part 300 in the embodiment includes a semi-circle spiral thread 310, and the semi-circle spiral thread 310 is used to connect to the connection position 26 on the inner wall of the cap body 20. The semi-circle spiral thread 310 has a rotation guide function. When the valve structure 10 is assembled, the valve structure 10 is pushed upward and twisted to make the semi-circle spiral thread 310 to rotate. During the rotation, the semi-circle spiral thread 310 is under an upward pushing force, which causes the semi-circle spiral thread 310 during rotation to rotate upward to the connection position 26 (for example, a groove position to achieve a snap connection). By using the semi-circle spiral thread 310, the entire valve structure 10 can be stably connected to the cap body 20, and the entire valve structure 10 will not fall off from the cap body 20 after the bottle is impacted (such as dropped). In addition, the connection position 26 of the cap body 20 may be configured as a threaded inner ring, which matches the semi-circle spiral thread 310. The threaded inner ring and the semi-circle spiral thread 310 form a tight fit. A contour of the semi-circle spiral thread 310 is curve-shaped, and a protruding thickness of the contour is smaller. Specifically, a thickness between an outermost protrusion of the semi-circle spiral thread 310 and an outer wall of the rigid connecting portion 100 is 0.3-0.7 mm; in this way, the squeeze fit is achieved during twisting, so that the valve structure 10 is more firmly fixed with the cap body 20.
