Description

Technical Field

[0001] This application relates to the technical field of solvent containers, and more specifically to a container with adjustable flow rate. Background Technology

[0002] Liquid solvents, such as those with insect-repellent, mosquito-repellent, anti-itch, or soothing functions, are generally stored in a container for convenience during transport and use. Currently, most liquid containers on the market are sprayers or glass bottles with a dispensing hole. While these containers can hold solvents, they generally cannot adjust the flow rate according to the actual application scenario or target object. This results in a single, unadjustable solvent flow rate. Utility Model Content

[0003] This application addresses the aforementioned shortcomings of the prior art by providing a container whose flow rate can be adjusted as needed, thus meeting the needs of different usage scenarios.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a container with adjustable flow rate. The structure of the device includes a bottle body for holding solvent. The open end of the bottle body is provided with a first cap that is interference-fitted with it. A second cap is screwed onto the first cap. The first cap is provided with a first through hole communicating with the bottle body and a flow regulating column. The second cap is provided with a second through hole for accommodating the flow regulating column. During the process of screwing the second cap relative to the first cap body, the flow regulating column and the second through hole form a gap of varying size or completely block the second through hole, and the solvent is drawn out from the gap.

[0005] With the above structure, this application provides two caps on the bottle body that can be screwed onto each other. The size of the gap between the flow regulating column and the second through hole is adjusted by the relative positions of the two caps after they are screwed onto each other. The solvent then flows out through this gap and into the outside of the second cap for use. The size of the gap can be adjusted, so the flow rate of the solvent can be controlled according to the needs of the application scenario to meet the usage requirements of different scenarios. Moreover, the flow rate adjustment is also very convenient. It can be adjusted simply by screwing the second cap up and down relative to the first cap, making the operation convenient and quick.

[0006] Furthermore, the flow regulating column is a frustum-shaped structure with its outer diameter gradually decreasing from the end near the bottle to the end of the second cap, and the inner diameter of the second through hole is located between the outer diameters of the upper and lower end faces of the frustum. With this structure, when the second cap is closer to the end of the flow regulating column near the bottle, the flow regulating column can enter the second through hole through this point to block the second through hole. When the second cap is away from the end of the flow regulating column near the bottle, a gap is formed between the flow regulating column and the second through hole. The size of this gap can change according to the axial distance between the two, thereby controlling the solvent flow rate.

[0007] Furthermore, the second cover body is axially provided with an inner cover extending toward the first cover body, and the inner cover is sealed to the hole wall of the first cover body; with this structure, when the solvent drawn out from the first cover body flows out, it can flow out completely from the gap between the flow regulating column and the second through hole, without leaking from the connection between the two covers bodies.

[0008] Furthermore, the second cover is provided with a ball bearing, which is rotatably housed in the first groove of the second cover and protrudes from the upper surface of the second cover. With this structure, when using solvent, the solvent is introduced into the first groove from the opening of the second cover and then contacts the ball bearing in the first groove. The ball bearing rolls under the action of external force, thereby applying the solvent to the surface to be coated, achieving uniform coating. It is not necessary to directly contact the solvent with your hands, and the coating is convenient and uniform.

[0009] Furthermore, the second cover is also provided with a second groove, which is located below the first groove and is arranged around the perimeter. With this structure, when the solvent is drawn out from the gap, it will enter the annular second groove. At this time, the second groove becomes a reservoir for the solvent, so that the solvent can have sufficient contact with the ball, making the ball smoother and less dry during rotation.

[0010] Furthermore, a third cap is provided on the outside of the first and second caps, and the third cap is screwed onto the bottle body; this structure can seal and protect the first and second caps to prevent excessive solvent evaporation or leakage.

[0011] Furthermore, the first cover is provided with an external thread, and below the external thread are a first protrusion and a second protrusion that protrude radially outward along the outer wall of the first cover. The first and second protrusions are spaced apart, and the circumferential extension length of the first protrusion is greater than that of the second protrusion. Correspondingly, the second cover is provided with an internal thread, and below the internal thread are a third protrusion and a fourth protrusion that protrude radially inward along the inner wall of the second cover. The third and fourth protrusions are spaced apart, and the circumferential extension length of the third protrusion is greater than that of the fourth protrusion. The first, second, third, and fourth protrusions are used to limit the axial distance between the second cover and the first cover during the screwing process of the second cover relative to the first cover. With the above structure, this application achieves the limitation of the distance between the two covers during the screwing process of the second cover relative to the first cover by setting the protrusions of different sizes on the two covers. This allows adjustment of the gap between the second through hole and the flow regulating column, realizing the control or blocking operation of the solvent flow rate.

[0012] Furthermore, both sides of the first and second protrusions along the axial direction are inclined surfaces. The two inclined surfaces of the first and second protrusions are inclined in the same direction, and the inclined surfaces between the first and second protrusions are inclined in opposite directions. With this structure, when the second cover rotates along the first cover in one direction, the protrusions can easily pass each other to adjust the flow rate. In the reverse rotation process, the protrusions of the second cover and the protrusions of the first cover can abut against each other to achieve circumferential rotation limit.

[0013] Furthermore, during the rotation of the second cover relative to the first cover, the protrusions on both always interfere with each other axially. By adopting the above structure, the protrusions on the two covers are axially set to a sufficient length, so that during the axial lifting and lowering process of the second cover relative to the first cover, the protrusions on both can always achieve radial interference, realize circumferential limiting function, and prevent the second cover from separating from the first cover during the flow rate adjustment process (at this time, the two larger protrusions abut against each other and can no longer rotate, ensuring that the second cover does not separate from the first cover).

[0014] Furthermore, the first and second covers each have two sets of protrusions, and the two sets of protrusions on each cover are axially symmetrical about each other along the axial direction of the cover; with this structure, circumferential limiting can be better achieved when the second cover is screwed.

[0015] Furthermore, when the second protrusion is located between the third and fourth protrusions in the same group, the flow regulating post blocks the second through hole; when the first and second protrusions are located between the third and fourth protrusions in different groups, there is a gap between the flow regulating post and the second through hole; through this limitation, the flow rate adjustment and the complete blocking state can be achieved.

[0016] Furthermore, an indicator arrow is provided on the outer peripheral surface of the second cover, and a switch mark is provided on the corresponding outer peripheral surface of the first cover; this setting can guide the operator to intuitively determine at what position the second cover is turned to be in the closed or open state, avoiding damage caused by excessive turning.

[0017] Furthermore, a vibration assembly is provided at the opposite end of the bottle body to the second cap. The vibration assembly includes a vibration motor and a switch button. The vibration motor is embedded inside the bottle body, and the switch button is located on the end face of the bottle body. A battery and a switch plate are also provided between the switch button and the vibration motor. The switch button abuts against the switch plate, and the battery is isolated from the vibration motor and the switch plate through the EVA material layer. The switch plate, battery, and vibration motor are electrically connected. With this structure, when using the device, after the solvent is applied to the skin by the roller ball, pressing the switch button activates the vibration motor under the power of the battery. This allows the bottle body to vibrate, enabling the solvent to penetrate the affected area more thoroughly, improving the performance of the solvent for insect repellency, antipruritic effects, and soothing. Moreover, the EVA material layer can prevent interference between the switch plate and the vibration motor. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] As attached Figure 1-14 As shown, this application discloses a flow-adjustable container. The device includes a bottle a for holding solvent, with a first cap 1 fitted to the open end of the bottle a. A second cap 2 is screwed onto the first cap 1. The first cap 1 has a first through hole 101 communicating with the bottle a and a flow-adjusting column 102. The second cap 2 has a second through hole 201 for accommodating the flow-adjusting column 102. During the screwing process of the second cap 2 relative to the first cap 1, the flow-adjusting column 102 and the second through hole 201... The solvent is drawn out from the gap by either forming a gap of varying size or completely blocking the second through hole 201. Specifically, a partition is radially arranged inside the first cover 1, and two axially symmetrical first through holes 101 are arranged on the partition. An axially upward-extending flow regulating column 102 is arranged at the axial center position. The flow regulating column 102 can extend into or be adjacent to the second through hole 201 according to the screw position of the second cover 2 relative to the first cover 1 to adjust the solvent flow rate in the bottle 2. The container described in this application can be used to hold solvents of liquids with functions such as mosquito repellent, insect repellent, antipruritic, and soothing.

[0037] With the above structure, this application provides two caps on the bottle body that can be screwed onto each other. The size of the gap between the flow regulating column and the second through hole is adjusted by the relative positions of the two caps after they are screwed onto each other. The solvent then flows out through this gap and into the outside of the second cap for use. The size of the gap can be adjusted, so the flow rate of the solvent can be controlled according to the needs of the application scenario to meet the usage requirements of different scenarios. Moreover, the flow rate adjustment is also very convenient. It can be adjusted simply by screwing the second cap up and down relative to the first cap, making the operation convenient and quick.

[0038] As attached Figure 3 , Figure 6-7 As shown, the flow regulating column 102 described in this application is a frustum-shaped structure with its outer diameter gradually decreasing from the end near the bottle body 1 to the end of the second cap 2. The inner diameter of the second through hole 201 is located between the outer diameters of the upper and lower end faces of the frustum. That is, the diameter of the second through hole 201 is sufficient to accommodate part of the flow regulating column 102. With this structure, when the second cap 2 is closer to the end of the flow regulating column 102 near the bottle body 1, the flow regulating column 102 can enter the second through hole 201 through this point and block the second through hole 201. When the second cap 2 is away from the end of the flow regulating column 102 near the bottle body 1, a gap is formed between the flow regulating column 102 entering the second through hole 201 and the second through hole 2, or there is a gap between the two in the axial direction. The size of this gap can change according to the axial distance between the two, thereby realizing the control of the solvent flow rate.

[0039] As attached Figure 3-5 and Figure 7 As shown, the second cover 2 of this application is axially provided with an inner cover 202 extending toward the first cover 1. The inner cover 202 is sealed to the inner wall of the first cover 1. Specifically, the inner cover 202 extends to the inner side of the first cover 1 and is sealed to its inner wall. With this structure, when the solvent drawn from the first cover 1 flows out, it can flow out completely from the gap between the flow regulating column 102 and the second through hole 201, without leaking from the connection between the two covers.

[0040] As attached Figure 3-7 and Figure 13 As shown, the second cover 2 of this application is provided with a ball bearing 3. The ball bearing 3 is rotatably housed in the first groove 203 of the second cover 2, and the ball bearing 3 protrudes from the upper end surface of the second cover 2. Specifically, the ball bearing can be a cylindrical structure with two spherical ends, which is rotatably connected to the first groove through an interference fit along the length direction, and the ball bearing is not easily disengaged from it. The concave contour of the first groove 203 is adapted to the structure of the ball bearing 3. With this structure, when using solvent, the solvent is introduced into the first groove 203 from the opening of the second cover 2, and then comes into contact with the ball bearing 3 in the first groove 203. The ball bearing 3 rolls under the action of external force, thereby applying the solvent to the surface to be coated, achieving uniform coating, without the need for direct contact with the solvent by hand, and the coating is convenient and uniform.

[0041] As attached Figure 3-7 and Figure 13As shown, the second cover 2 of this application is further provided with a second groove 204. The second groove 204 is located below the first groove 203 and is arranged around the circumference. Specifically, the second groove 204 is located inside the second cover 2 and below the ball bearing 3, and is connected to the first groove 203. After the solvent is drawn out from the outlet, it can first enter the second groove 204 and then enter the first groove 203 to contact the ball bearing. With this structure, when the solvent is drawn out from the gap, it will enter the annular second groove 204. At this time, the second groove 204 becomes a reservoir for the solvent, so that the solvent can achieve sufficient contact with the ball bearing 3, thereby making the ball bearing 3 smoother and less dry during rotation.

[0042] As attached Figure 1-4 As shown, a third cover 4 is also provided on the outside of the first cover 1 and the second cover 2 described in this application. The third cover 4 is screwed into the bottle a. That is, the port of the bottle a is provided with an external thread, and the corresponding third cover 4 is provided with an internal thread. The two are screwed together. With this structure, the first cover 1 and the second cover 2 can be sealed and protected to prevent excessive evaporation or leakage of solvent.

[0043] As attached Figure 3-5 , Figure 7-14 As shown, the first cover 1 of this application is provided with an external thread. Below the external thread, a first protrusion 103 and a second protrusion 104 are provided, protruding radially outward along the outer wall of the first cover 1. The first protrusion 103 and the second protrusion 104 are spaced apart (spaced apart along the circumferential direction of the outer wall of the first cover), and the circumferential extension length of the first protrusion 103 is greater than the circumferential extension length of the second protrusion 104 (i.e., the first protrusion 103 extends wider in the circumferential direction). Correspondingly, the second cover 2 is provided with an internal thread, and below the internal thread, a third protrusion 20 is provided, protruding radially inward along the inner wall of the second cover 2. 5 and the fourth protrusion 206, the third protrusion 205 and the fourth protrusion 206 are spaced apart (spaced apart along the circumferential direction of the inner wall of the second cover), and the circumferential extension length of the third protrusion 205 is greater than the circumferential extension length of the fourth protrusion 206 (i.e., the third protrusion 205 extends wider in the circumferential direction); the first protrusion 103, the second protrusion 104, the third protrusion 205 and the fourth protrusion 206 are used to limit the axial distance between the second cover 2 and the first cover 1 during the screwing process of the second cover 2 relative to the first cover 1; that is, the screwing process achieves the limiting function of the screwing position through the setting of the protrusions, specifically, as shown in the attached figure. Figure 9 As shown, the second through hole is blocked at this time, and the solvent cannot flow out; as shown in the attached figure. Figure 10As shown, the first and third protrusions are circumferentially abutting each other, and the second through hole is in the maximum flow state. As shown in Figure 11, the solvent can flow out at this time. By screwing the second cover, different flow rates can be adjusted within the circumferential stroke range shown in the figure. With the above structure, this application sets the axial distance between the two covers 2 and the first cover 1 during the screwing process, thereby adjusting the gap between the second through hole 201 and the flow regulating column 102 to control or block the solvent flow rate.

[0044] As attached Figure 9-12 As shown, the two sides of the first protrusion 103 and the second protrusion 104 extending along the axial direction in this application are both inclined surfaces. The inclination directions of the two inclined surfaces of each of the first protrusion 103 and the second protrusion 104 are the same (i.e., the inclination directions of the two inclined surfaces of the protrusion itself are the same), and the inclination directions of the inclined surfaces between the first protrusion 103 and the second protrusion 104 are opposite (i.e., the inclination directions of the inclined surfaces on corresponding sides between the two protrusions are opposite). With this structure, when the second cover 2 rotates along the first cover 1 in one direction, the protrusions can easily pass each other. This allows for flow rate adjustment, while the reverse rotation process allows the protrusions of the second cover 2 to abut against the protrusions of the first cover 1, achieving circumferential rotational limitation. More specifically, the third protrusion 205 of this application has two surfaces extending axially: one side is a flat surface, and the other side is a rounded arc surface, facilitating rotation over the protrusions on the first cover 1 from this side, while rotation from the opposite side is less likely to overtake, thus achieving limitation. The fourth protrusion 206 of this application has a rounded arc edge overall, which does not serve a limiting function. The limiting function is provided by two large protrusions, specifically as follows... Figure 10 As shown, circumferential limiting is achieved at this time.

[0045] As an example, during the rotation process of the second cover 2 relative to the first cover 1, the protrusions on both always interfere with each other in the axial direction; that is, the protrusions on the two covers are staggered vertically in the axial direction, with no axial gap between them. Using the above structure, the protrusions on the two covers are axially set to a sufficient length, ensuring that during the axial lifting and lowering process of the second cover 2 relative to the first cover 1, the protrusions on both can always achieve radial interference, realizing a circumferential limiting effect and preventing the second cover 2 and the first cover 1 from separating during the flow rate adjustment process (as shown in the attached diagram). Figure 10 As shown, when the two large protrusions on the two covers abut against each other, the second cover 2 can no longer rotate, ensuring that the second cover 2 will not detach from the first cover 1, facilitating reset and flow adjustment.

[0046] As attached Figure 9-12 , Figure 14As shown, the first cover 1 and the second cover 2 of this application each have two sets of protrusions, and the two sets of protrusions on each of the two covers are axially symmetrical about each other along the axial direction of the cover; that is, one set of protrusions on each cover can overlap with the corresponding protrusion in the other set when rotated 180 degrees circumferentially. With this structure, when the second cover 2 is screwed on, the arrangement of the two sets of protrusions can better achieve circumferential limiting; more specifically, as shown in the attached... Figure 9-12 As shown, the circumferential distance between the first protrusion 103 and the second protrusion 104 in each group on the first cover 1 is less than the distance between the components. Similarly, the circumferential distance between the third protrusion 205 and the fourth protrusion 206 in each group on the second cover 2 is less than the distance between the components. Furthermore, the circumferential distance between the first protrusion 103 and the second protrusion 104 in each group of this application is not less than the circumferential distance between the third protrusion 205 and the fourth protrusion 206 in each group on the second cover 2.

[0047] As attached Figure 9 As shown, when the second protrusion 104 is located between the third protrusion 205 and the fourth protrusion 206 in the same group (i.e., the third and fourth protrusions that are paired with each other in the same group), the flow regulating column 102 blocks the second through hole 201; as shown in the attached figure. Figure 11 As shown, when the first protrusion 103 and the second protrusion 104 in the same group are located between the third protrusion 203 and the fourth protrusion 206 in different groups (the third protrusion 203 in one group and the fourth protrusion 206 in another group), there is a gap between the flow regulating column 102 and the second through hole 201; by limiting this scheme, the adjustment of the flow rate can be realized and the conversion to a completely blocked state can be achieved.

[0048] As attached Figure 6 As shown, the outer peripheral surface of the second cover 2 described in this application is provided with an indicator arrow 207, and the corresponding outer peripheral surface of the first cover 1 is provided with a switch mark 105 (the specific switch mark 105 includes an ON mark indicating that the flow can be turned on, and an OFF mark indicating that the flow is turned off and not flowing). With this setting, when the second cover 2 is rotated relative to the first cover 1, the operator can be guided to intuitively judge at what position the second cover is rotated to be in the closed or open state by observing the position of the indicator arrow 207 and the switch mark 105, so as to avoid damage to the device caused by excessive rotation.

[0049] As attached Figure 5 , Figure 7 and Figure 15As shown, the bottle body a described in this application is further provided with a vibration assembly at the opposite end of the second cap 2. The vibration assembly includes a vibration motor 5 and a switch button 6. The vibration motor 5 is embedded inside the bottle body a, and the switch button 6 is located on the end face of the bottle body a. A battery 7 and a switch plate 8 are also provided between the switch button 6 and the vibration motor 5. The switch button 6 abuts against the switch plate 8. The battery 7 is isolated from the vibration motor 6 and the switch plate 8 through the EVA material layer 9. The switch plate 8, the battery 7, and the vibration motor 5 are electrically connected (to drive the switch plate 8 to control the vibration motor 5 to turn on and off when the switch button 6 is pressed). The battery provides electrical power for the vibration motor 5 to operate; the battery can be a disposable battery or a rechargeable battery. Specifically, the vibration motor 5, switch button 6, battery 7, switch plate 8, and EVA material layer in this application are all commercially available products. The switch adopts this structure, and when the device is used, after the solvent is applied to the skin through the roller ball, the switch button 6 is pressed to activate the switch plate 8, which is driven by the power of the battery 7, so that the vibration of the bottle can more thoroughly penetrate the solvent into the affected area, improving the insect repellent, antipruritic, and soothing effects of the solvent. Moreover, the EVA material layer in this application is set with double layers to sandwich the battery 7 inside, which can avoid mutual interference between the switch plate 8 and the vibration motor 5.

[0050] The working principle and process of this flow-adjustable container for adjusting the flow rate are as follows: First, the first cap 1 is inserted and assembled into the opening end of the solvent-containing bottle a, and the two are tightly sealed to prevent the first cap 1 from detaching from the bottle or leaking. Then, the second cap 2 is assembled with the first cap 1 by screwing it on. An inner cap 202 is provided inside the second cap 2 to achieve a seal at the connection between the two. The solvent can only flow out from the first through hole 101 on the first cap 1 and then flow out through the gap formed between the flow adjustment column 102 and the second through hole 201. When it is necessary to apply the solvent, the third cap 4 is removed, and then the second cap 2 is circumferentially screwed relative to the first cap 1. While rotating circumferentially, the second cap moves upward in the axial direction relative to the first cap. This process causes the gap between the flow adjustment column 102 and the second through hole 201 to gradually increase. This process can be shown in Figure 11, gradually screwing until the desired flow rate is reached. Figure 10 In the state shown, the two large protrusions inside the two covers are abutting each other, limiting the flow rate. Twisting in either direction will reduce the flow rate again, until it is turned to the maximum. Figure 9 In the state shown, the first protrusion 103 on the first cover 1 is positioned between the third protrusion 205 and the fourth protrusion 206 in the same group on the second cover 2. The first cover 1 is screwed down until its lower end face abuts against the radial boss of the second cover 2, specifically as follows. Figure 5-7As shown, at this time, the flow regulating column 102 completely blocks the second through hole 201, realizing the closing action of the container; therefore, this structure of the present application realizes for the first time that the flow rate can be adjusted by rotating the distance between the first cover and the second cover in the axial direction, and the limiting structure avoids disengagement caused by excessive rotation. It is also equipped with an opening and closing indicator mark, which is convenient to operate and can adjust the amount of solvent used according to different scenarios.
