1 is a perspective view showing a cap for quantitative outflow of liquid according to a first embodiment of the present invention. FIG. 2 is an exploded perspective view of the liquid quantitative outflow cap of FIG. 1, and a part of the chamber 121 is cut out for convenience of description.

As shown in FIGS. 1 and 2, the cap for liquid quantitative outflow may include a connection part 110, a metering part 120, and an opening/closing part 140.

The connection part 110 may be detached from the inlet of the container 10 in which the liquid is accommodated. Hereinafter, for convenience of description, the liquid is described as water.

The connection part 110 may have an appropriate shape according to the shape of the inlet of the container 10 to be coupled. For example, when a thread is formed on the outer circumferential surface of the inlet of the container 10, the connection 110 may also have a thread on the inner circumferential surface. Alternatively, when the outer circumferential surface of the inlet of the container 10 is flat, the inner circumferential surface of the connection portion 110 may also be formed flat. The inlet of the connection part 110 and the container 10 may have the same central axis.

The metering unit 120 may be connected to the upper portion of the connection unit 110. The metering unit 120 may be integrally formed with the connection unit 110, but is not limited thereto.

The metering unit 120 may have a chamber 121, an inlet 123 and an outlet 124.

The chamber 121 is a part that forms the body of the metering unit 120 and may have an accommodation space 122 inside. In addition, the chamber 121 may be formed such that its central axis crosses the central axis of the connection unit 110. For example, the central axis of the chamber 121 may be perpendicular to the central axis of the connection unit 110.

The accommodation space 122 may have the same central axis as the central axis of the chamber 121 and may be formed in a cylindrical shape, and may be opened to one side of the chamber 121.

The inlet 123 may be formed through the chamber 121 to connect the inlet of the container 10 and the receiving space 122. The inlet 123 may be formed through the lower portion of the chamber 121 and the connection portion 110. The inlet 123 may be opened or closed, and when the inlet 123 is opened, water contained in the container 10 may flow into the receiving space 122 through the inlet 123.

The outlet 124 is formed through the chamber 121 to connect the receiving space 122 to the outside. The outlet 124 may be formed through the upper portion of the chamber 121. The outlet 124 may be opened and closed, and when the outlet 124 is opened and inclined downward, the water contained in the receiving space 122 may be discharged to the outside through the outlet 124 by gravity.

The metering unit 120 may further have a guide 126. The guide 126 is formed on the outer circumferential surface of the chamber 121 and is connected to the outlet 124 to guide the flow of water flowing out to the outlet 124.

The guide 126 may have a first guide 127 and a second guide 128.

The first guide 127 may be formed to surround a part of the outlet 124 to guide the flow of water flowing out of the outlet 124 upward. The first guide 127 may be formed to have a relatively wide cross-sectional area, and through this, it is possible to implement a function of a cup that allows a user to drink water flowing out from the outlet 124. That is, the user puts his mouth on the first guide 127 and tilts the container 10 to drink when the water contained in the receiving space 122 flows out through the outlet 124.

The second guide 128 is formed to surround another part of the outlet 124 and may be connected to the first guide 127. The second guide 128 may be formed to have a smaller cross-sectional area than the first guide 127. When water flowing through the outlet 124 flows out to the second guide 128, external air may flow into the accommodation space 122 through the first guide 127. Therefore, the water flowing out to the second guide 128 can be followed while forming a smooth curve, and the drop point can be predicted.

The opening/closing unit 140 may be coupled to the metering unit 120 and rotated in both directions based on the central axis of the chamber 121 to selectively open and close the inlet 123 and the outlet 124. Through this, the opening and closing unit 140 allows the water of the container 10 to flow into the inlet 123 to be filled into the receiving space 122, or the water filled in the receiving space 122 is discharged to the outside through the outlet 124 You can do it.

The sealing plate 141 may be in close contact with one side of the chamber 121. A flange 125 may protrude along the circumferential direction at one end of the chamber 121. The sealing plate 141 may be formed to have a diameter corresponding to the outer diameter of the flange 125 and may be in close contact with the flange 125. As the sealing plate 141 is in close contact with the flange 125, the contact area can be further increased, and through this, one side of the receiving space 122 can be more reliably sealed by the sealing plate 141.

The valve 142 may protrude from one side of the sealing plate 141. The valve 142 may be bent to have an outer diameter corresponding to the inner diameter of the receiving space 122. In addition, the valve 142 may be formed partially open. That is, the valve 142 may have both ends 143 spaced apart from each other based on the circumferential direction. Accordingly, the valve 142 may have a circumferential length shorter than the circumferential length of the receiving space 122, and preferably may have a circumferential length longer than half of the circumferential length of the receiving space 122.

The valve 142 is inserted into the receiving space 122 and rotates in both directions with respect to the central axis of the chamber 121, while the inlet 123 is opened and the outlet 124 is closed so that the water in the container 10 is discharged from the inlet 123 The inlet position to be introduced into the receiving space 122 and filled in the receiving space 122, the inlet 123 and the outlet 124 are closed to a sealed position where the receiving space 122 is sealed, and the inlet 123 is closed and the outlet 124 Is opened and the water filled in the receiving space 122 may be selectively located at any one of the outlet locations where the water is discharged to the outside through the outlet 124.

3 is an exemplary view for explaining the operation of the liquid quantitative outflow cap of FIG. 1, for convenience of explanation, the guide 126 is omitted so that the outlet 124 is exposed.

Figure 3 (a) shows a state in which the valve 142 is located at the inlet position. When the valve 142 is rotated clockwise to open the inlet 123 and the outlet 124 is closed, the container The water of 10 may be introduced through the inlet 123 and be accommodated in the accommodation space 122.

In addition, Figure 3 (b) shows a state in which the valve 142 is located in the closed position. When the valve 142 rotates counterclockwise so that the inlet 123 along with the outlet 124 is also closed, water Silver may be stably accommodated in the accommodation space 122.

3(c) shows a state in which the valve 142 is located at the outlet position, and in the state of FIG. 3(b), the valve 142 further rotates counterclockwise so that the inlet 123 is closed. If the state is maintained and only the outlet 124 is opened, the water contained in the receiving space 122 can be discharged through the outlet 124.

The opening and closing part 140 may have a handle 144, and the handle 144 may be formed to protrude from the other side of the sealing plate 141. An external force may be input to the handle 144, through which the opening and closing part 140 may be rotated. That is, the user can rotate the valve 142 in both directions by holding and turning the handle 144.

The volume of the receiving space 122 may be appropriately designed according to the amount of water to be discharged once. That is, when the volume of the receiving space 122 is determined, the user can easily secure the amount of water to be discharged by allowing the receiving space 122 to be filled with water. Therefore, it is possible to accurately discharge a desired amount of water without a separate meter for measuring the amount of water to be discharged.

And, the state of the valve 242 in each of (a), (b) and (c) of Fig. 7 corresponds to the state of the valve 142 in (a), (b) and (c) of Fig. 3, respectively. Can be.

First, as shown in (b) of FIG. 7, when the locking protrusions 262a and 262b of the elastic portion 260 are in close contact with both sides of the first stopper 246, the valve 242 is shown in ( As in b), both the inlet 223 and the outlet 224 may be closed. That is, when an external force is not applied to the grip part 270 and the grip part 270 does not rotate, the valve 242 may be in a state in which both the inlet 223 and the outlet 224 are closed.

Then, as shown in Figure 7 (a), when the grip portion 270 rotates clockwise, one end of the locking protrusion 262a is caught by the second stopper 231, the other end of the locking protrusion 262b Is moved clockwise by the first stopper 246. And as the valve 242 is further rotated in a clockwise direction, the valve 242 may have the inlet 223 open and the outlet 224 closed, as shown in FIG. 3A. The rotation of the grip part 270 may be until the wing 272a on one side contacts the third stopper 232a on one side and cannot be rotated any more. The user can easily grasp that the inlet 223 is open and the outlet 224 is closed by rotating until the wing 272a on one side of the grip unit 270 contacts the opposite third stopper 232a. In addition, at this time, since the elastic body 261 is in a deformed state, when the external force applied to the grip part 270 is lost, the valve 242 rotates counterclockwise due to the elastic restoring force of the elastic body 261, and FIG. It will return to the state of (b).

On the other hand, as shown in (c) of Figure 7, when the grip portion 270 rotates in a counterclockwise direction, the locking protrusion 262b of the other end is caught by the second stopper 231, and the locking protrusion 262a of one end ) Is moved in a counterclockwise direction by the first stopper 246. And as the valve 242 is further rotated counterclockwise, the valve 242 may have the inlet 223 closed and the outlet 224 open as shown in FIG. 3C. The rotation of the grip part 270 may be until the wing 272b on the other side contacts the third stopper 232b on the other side and cannot be rotated any more. The user can easily grasp that the inlet 223 is closed and the outlet 224 is opened by rotating until the wing 272b on the other side of the grip unit 270 touches the opposite third stopper 232b. Likewise, even at this time, since the elastic body 261 is in a deformed state, when the external force applied to the grip part 270 disappears, the valve 242 rotates in a clockwise direction by the elastic restoring force of the elastic body 261.

8 is a perspective view showing a cap for liquid quantitative outflow according to a third embodiment of the present invention, FIG. 9 is an exploded perspective view of FIG. 8, and FIG. 10 is a perspective view showing an opening and closing part of FIG.

As shown in FIGS. 8 to 10, the cap for liquid quantitative outflow according to this embodiment includes a connection part 310, a metering part 320, an opening and closing part 340, an elastic part 360, and an insert plug 370 can do.

The connection part 310 may be detached from the container 10 at the entrance.

The metering part 320 may be connected to the upper part of the connection part 310, and may have a chamber 321, an inlet 323 and an outlet 324.

The chamber 321, the inlet 323, and the outlet 324 may be as described in the second embodiment. That is, the chamber 321 is a portion that forms the body of the metering unit 320 and may have an accommodation space 322 inside. Further, the inlet 323 may be formed through the chamber 321 to connect the inlet of the container 10 and the receiving space 322. The outlet 324 is formed through the chamber 321 to connect the receiving space 322 to the outside.

And, the metering unit 320 may further have a guide 326. The guide 326 may be formed to surround the outlet 324, guide the flow of water flowing out to the outlet 324 and may function as a cup.

The opening/closing part 340 may have a sealing plate 341 and a valve 342. The sealing plate 341 and the valve 342 may be the same as described in the second embodiment. That is, the sealing plate 341 may have an insertion groove 345 recessed along the circumferential direction on the outer circumferential surface, and a first stopper 346 formed in a portion of the insertion groove 345.

The elastic part 360 may also be the same as described in the second embodiment. That is, the elastic part 360 may have an elastic body 361 and the locking protrusions 362a and 362b, and when the elastic body 361 is inserted into the insertion groove 345, the locking protrusions 362a and 362b are Each may be in close contact with both side surfaces of the first stopper 346.

In addition, the chamber 321 may further have a second stopper 331, and the second stopper 331 may be formed at one end of the chamber 321. The second stopper 331 may extend in the axial direction of the chamber 321 so as to be positioned above the first stopper 346. When the first stopper 346 is located under the second stopper 331, the locking protrusions 362a and 362b of the elastic part 360 may be in close contact with both sides of the second stopper 331, respectively. For this purpose, the second stopper 331 may be formed to have the same width as the first stopper 346 along the circumferential direction.

On the other hand, in the present embodiment, the cap for quantitative outflow of liquid may include a separation prevention unit 335.

The departure prevention part 335 may have a separation prevention protrusion 348 and a separation prevention groove 336, and the opening/closing part 340 and the metering part 320 may not be separated from each other.

The separation preventing protrusion 348 may be formed to protrude in a predetermined length along the circumferential direction on the outer circumferential surface of the valve 342 or the inner circumferential surface of the chamber 321. In this embodiment, it will be described that the separation preventing protrusion 348 is formed on the outer peripheral surface of the valve 342.

The separation prevention groove 336 may be formed along the circumferential direction on a surface on which the separation prevention protrusion 348 is not formed in the outer circumferential surface of the valve 342 or the inner circumferential surface of the chamber 321. In this embodiment, it will be described that the departure preventing protrusion 348 is formed on the inner peripheral surface of the chamber 321.

The departure prevention groove 336 may be formed to extend to a length longer than the length of the separation prevention protrusion 348, and the separation prevention groove 336 may guide the movement of the separation prevention protrusion 348. Therefore, when the valve 342 is inserted into the receiving space 322 and rotates, the departure prevention protrusion 348 may be moved along the separation prevention groove 336 in a state coupled to the separation prevention groove 336 , Through this, it is possible to prevent the opening and closing unit 340 from being separated from the metering unit 320.

In addition, the opening/closing part 340 may further have a pressing part 351. The pressurizing part 351 is protruded from one side of the sealing plate 341 so as to be positioned between both ends of the valve 342 so that the valve 342 may be in close contact with the inner circumferential surface of the chamber 321.

Specifically, the pressing part 351 may have a pressing plate 352 and a support rib 353.

The pressure plate 352 may be formed to protrude from one side of the sealing plate 341 so as to be positioned between the both ends 343 of the valve 342. The pressure plate 352 may have an outer diameter larger than an inner diameter of the chamber 321. Therefore, when the pressure plate 352 is inserted into the receiving space 322, the pressure plate 352 may be pressed by the chamber 321 and deformed in the center direction. And, as the pressure plate 352 is deformed in this way, a restoring force is generated in the pressure plate 352 to restore it to its initial shape. As the pressure plate 352 presses the inner circumferential surface of the chamber 321 in an outward direction by this restoring force, the valve 342 may evenly adhere to the inner circumferential surface of the chamber 321, and the valve 342 and the chamber 321 The gap between the inner peripheral surfaces of the can be minimized.

The support rib 353 may protrude from the inner circumferential surface of the pressure plate 352, and the support rib 353 may extend in the longitudinal direction of the pressure plate 352. The support rib 353 may support the pressure plate 352 so that the restoring force of the pressure plate 352 is greater and more effective.

The separation prevention protrusion 348 of the separation prevention part 335 may be further provided in the pressure plate 352 and a pair may be provided in the opening/closing part 340. In this case, the separation preventing groove 336 may also be formed in a pair on the inner peripheral surface of the chamber 321.

And, as in the first embodiment, a handle 344 may be formed on the other side of the sealing plate 341.

The insert stopper 370 may have a lower surface 372 and an outer circumferential surface 371, and may be coupled to the connection part 310 and inserted into the inlet 11 of the container 10. The insert stopper 370 may be pressed against the connection part 310 and contracted so that the inlet 11 of the container 10 is airtight.

The airtight rib 312 may be formed to protrude along the circumferential direction on the lower surface of the upper plate 311 and may be in close contact with the inner circumferential surface of the inlet 11 of the container 10.

The connection part 310 may have a first pressurizing ring 313, and the first pressurizing ring 313 may be formed to protrude along the circumferential direction on the outer circumferential surface of the airtight rib 312. The first pressing ring 313 may be formed to have an outer diameter larger than the inner diameter of the inlet 11 of the container 10. Therefore, when the airtight rib 312 is inserted into the inlet 11 of the container 10, the first pressing ring 313 is pressed in the center direction by the inlet 11 of the container 10, and accordingly, the airtight rib (312) can also be contracted in the center direction. The first pressure ring 313 is in close contact with the inner circumferential surface of the inlet 11 of the container 10 so that the space between the first pressure ring 313 and the inlet 11 of the container 10 is airtight, It can be prevented from leaking between the airtight rib 312 and the inlet 11 of the container 10.

The insert plug 370 may be coupled to the inside of the hermetic rib 312. Insert stopper 370 may be provided in a state coupled to the inner side of the airtight rib 312, when the connection portion 310 is coupled to the inlet 11 of the container 10, the insert stopper 370 is a container ( It can be inserted into the inlet 11 of 10).

And, as the connection part 310 is screwed with the inlet 11 of the container 10, when the airtight rib 312 is contracted in the center direction from the inside of the inlet 11 of the container 10, the insert plug 370 is It can be pressed in the center direction by the airtight rib 312, through which, the inlet 11 of the container 10 can be airtight.

The insert plug 370 may have a second pressurizing ring 373. The second pressure ring 373 may be formed to protrude along the circumferential direction at a position corresponding to the first pressure ring 313 on the outer peripheral surface 371 of the insert stopper 370. In addition, the second pressing ring 373 may be formed to have an outer diameter corresponding to the inner diameter of the hermetic rib 312. Therefore, when the airtight rib 312 is contracted in the center direction, the second pressing ring 373 is pressed in the center direction by the airtight rib 312 so that the space with the airtight rib 312 is more effectively airtight.

When the water of the container 10 does not flow out, the user inserts the insert plug 370 into the connection part 310 and is coupled to the inlet 11 of the container 10, and the container 10 by the insert stopper 370 ) Of the inlet 11 can be made airtight. In addition, when the water from the container 10 is to be drained, the insert plug 370 is removed from the connection part 310, and then the connection part 310 may be combined with the inlet 11 of the container 10 to be used.

That is, when the handle 344 does not rotate because an external force is not applied to the handle 344, the valve 342 may be in a state in which both the inlet 323 and the outlet 324 are closed.

Then, as shown in (a) of FIG. 12, when the sealing plate 341 rotates clockwise, the locking protrusion 362a of one end is caught by the second stopper 331, and the locking protrusion 362b of the other end ) Is moved clockwise by the first stopper 346. In addition, as the valve 342 further rotates in a clockwise direction, the valve 342 may have the inlet 323 open and the outlet 324 closed as shown in FIG. 3A. The rotation of the sealing plate 341 may be until the departure prevention protrusion 348 is caught by one end of the separation prevention groove 336 and cannot be rotated any more. By rotating the handle 344 until the departure prevention protrusion 348 is caught on one end of the separation prevention groove 336 and cannot be rotated anymore, the inlet 323 is opened and the outlet 324 is closed. I can grasp it. In addition, at this time, since the elastic body 361 is in a deformed state, when the external force applied to the handle 344 is lost, the valve 342 rotates counterclockwise due to the elastic restoring force of the elastic body 361, and FIG. 12 It will return to the state of (b).

And as the valve 342 further rotates counterclockwise, the valve 342 may allow the inlet 323 to be closed and the outlet 324 to be opened as shown in FIG. 3C. The rotation of the sealing plate 341 may be until the departure prevention protrusion 348 is caught in the other end of the separation prevention groove 336 and cannot be rotated any more. By rotating the handle 344 until the departure prevention protrusion 348 is caught on the other end of the separation prevention groove 336 and cannot be rotated any more, the inlet 323 is closed and the outlet 324 is opened easily. I can grasp it. Likewise, even at this time, since the elastic body 361 is in a deformed state, when the external force applied to the handle 344 disappears, the valve 342 rotates in a clockwise direction due to the elastic restoring force of the elastic body 361.
