Description

  The present invention relates to a dispensing cap.

Conventionally, as a pouring cap, a first pouring member attached to the mouth of a container and having a first pouring port, and a first pouring member detachably mounted to open and close the first pouring port A configuration including a second pouring member in which a second pouring port having a smaller diameter than the first pouring port is formed is known (for example, see Patent Document 1).
In such a pouring cap, the amount of contents to be poured can be selectively changed by attaching and detaching the second pouring member to the first pouring member. That is, by removing the second pouring member from the first pouring member and opening the large-diameter first pouring member, a large amount of contents can be poured at once, and the second pouring member can be poured into the first pouring member. By mounting on the outlet member and covering the first outlet, a small amount of contents can be extracted from the second outlet having a small diameter through the first outlet.

JP 2005-41506 A

  However, the following problems remain in the conventional pouring cap. That is, when the second pouring member is attached to the first pouring member and a small amount of content is to be poured from the second pouring port, it is difficult to visually recognize the amount of content in the container from the small-diameter second pouring port. For this reason, for example, if the container is tilted suddenly, a large amount of contents may be poured out from the second pouring outlet at once, and the contents may not be poured out accurately.

  Then, an object of this invention is to provide the extraction cap which can be poured out by adjusting the flow volume of the content from the 2nd small diameter outlet.

The present invention employs the following means in order to solve the above problems. That is, the pouring cap of the present invention is a pouring cap that is attached to the mouth portion of the container that contains the contents, and is attached to the mouth portion for pouring the contents in the container. A first pouring member in which a single pouring port is formed, and a closing portion in which a pull ring portion that forms a ring shape by closing the first pouring port is connected via a weakening portion that can be broken; and a hinge portion A second spout is formed that is connected to the first spout member through the cover and covers the first spout so as to be freely opened and has a smaller diameter than the first spout and communicates with the first spout. A second pipe-out member having a crest , wherein the second pipe-out member includes a barrier portion disposed below the second pouring port, and a plurality of supports that support the barrier portion from above. A plurality of communication ports are formed between the plurality of support portions, and the top wall portion of the second extraction member is It said second Note inclined so upward toward the outlet, the barrier unit is characterized that you located above the lower end of the side wall portion of the second dispensing member.

In the present invention, the content flowing out from the first pouring port is poured out from the second pouring port after the momentum is attenuated by colliding with the barrier portion, and therefore the amount of the content poured out from the second pouring port Can be controlled more accurately. That is, for example, when the container is tilted suddenly, the contents flow out vigorously from the first spout toward the second spout. However, since there is a barrier portion that overlaps the second outlet in a plan view between the first outlet and the second outlet, the outflowed contents collide with the barrier portion without directly facing the second outlet. . Then, the content flows along the flow path secured by the support portion in a state where the momentum is attenuated, and is discharged from the second spout. Therefore, it is possible to prevent the contents from jumping out or flowing out excessively, and to more accurately pour out the contents from the second spout having a smaller diameter than the first spout.
In the case of contents having a relatively low viscosity, when the contents are poured out from the second outlet by tilting the container, the contents are poured out and air is supplied into the container (air replacement). ) Is performed smoothly, so that the amount of extraction from the second outlet can be accurately controlled. In the case of contents having a relatively high viscosity, for example, by squeezing the container to increase the internal pressure of the container, the contents are poured out from the second outlet, and then the squeeze is stopped to reduce the internal pressure of the container. By lowering the content, the contents are sucked back from the second spout, so that the liquid runs out better. Therefore, in both cases where the content has a low viscosity and a high viscosity, the amount discharged from the second outlet can be accurately controlled.

Moreover, it is preferable that the pouring cap of this invention makes the cone shape which the said barrier part inclines toward the downward direction as it goes to radial direction outer side.
In this invention, when the container is placed in an upright posture after the content is poured out from the second pouring outlet, the content is returned into the container along the barrier portion, and the content is less likely to remain in the barrier portion.

Moreover, it is preferable that the pouring cap of the present invention includes an overcap that is connected to the second pouring member via a hinge portion and opens and closes the second pouring port.
In the present invention, the number of parts can be reduced by integrating the first and second extraction members and the overcap.

Moreover, it is preferable that the said cap part is inserted in the radial direction inner side of the ring part of the said pull ring part for the extraction | pouring cap of this invention.
In the present invention, by inserting the barrier portion inside the ring portion, it is not necessary to increase the height of the dispensing cap in order to prevent the barrier portion and the pull ring portion from interfering with each other even if the barrier portion is provided.

Moreover, in the pouring cap of this invention, it is preferable that the guide part extended toward the downward direction from the lower end of the said communicating port is provided in the position corresponding to the said communicating port in the said barrier part.
In this invention, when the container is in an upright posture, the contents are guided from the communication port along the side surface of the guide part and collected at the lower end of the guide part to form droplets. Can be collected in a container.

  According to the pouring cap according to the present invention, the content that has flowed out of the first pouring port is poured out from the second pouring port after the momentum is weakened by colliding with the barrier portion, and the second pouring port is discharged. Therefore, it is possible to adjust the flow rate of the content from the second outlet with a small diameter. In addition, when the viscosity of the contents is relatively low, when the container is tilted, the contents are smoothly poured out and air is supplied into the container (air replacement). Can be accurately controlled. Furthermore, in the case of the contents having a relatively high viscosity, for example, after the container is squeezed and the contents are poured out from the second outlet, the contents are sucked back from the second outlet when the squeeze is stopped. Since the liquid breakage is good, the amount dispensed from the second spout can be accurately controlled regardless of the viscosity of the contents.

The inner wall portion 32 has a cylindrical shape and is disposed on the radially inner side with respect to the outer wall portion 31. The inner wall portion 32 has an upper end connected to the outer wall portion 31 and is fitted in the mounting convex portion 21A.

The top wall 33 has a circular shape in plan view, and the outer periphery thereof is connected to the upper end of the inner wall 32 over the entire circumference. Moreover, the top wall part 33 has comprised the cone shape which inclines upwards as it goes to radial direction inner side. Further, an opening is formed in the central portion in the radial direction of the top wall portion 33, and an extraction cylinder portion 37 protruding upward is continuously provided at the peripheral portion of the opening.
The extraction cylinder portion 37 has a cylindrical shape, and the upper opening end thereof is a second outlet 37A having a smaller diameter than the first outlet 23A.

As shown in FIGS. 1 and 2, the barrier portion 34 is a circular plate member that overlaps the second spout 37A in a plan view, and is between the first spout 23A and the second spout 37A in the axial direction. It is arranged inside the ring portion 28 in the radial direction.
The plurality of support portions 35 extend along the axial direction so as to pass through the inside in the radial direction of the ring portion 28, and include a peripheral edge portion of the barrier portion 34 and a peripheral edge portion of the opening portion of the top wall portion 33. Connected. A plurality of support portions 35 are arranged at equal intervals in the circumferential direction on the peripheral portion of the barrier portion 34, and a barrier is provided while ensuring a flow path between the first spout 23A and the second spout 37A. The part 34 is supported from above. Further, between the two support portions 35 adjacent to each other in the circumferential direction, a communication port 35 </ b> A that allows the first pouring port 23 </ b> A and the second pouring port 37 </ b> A to communicate with the barrier portion 34 and the top wall portion 33.

As shown in FIG. 1, the overcap 13 has a top cylindrical shape, and includes a top plate portion 41 and a peripheral wall portion 42.
The top plate portion 41 has a circular shape in plan view, and a fitting tube portion that protrudes downward at the center portion in the radial direction of the top plate portion 41 and fits radially inside the extraction tube portion 37. 43 is provided.
The peripheral wall portion 42 has a cylindrical shape, and an engagement concave portion 42 </ b> A that engages with a flange portion 3 </ b> A protruding radially outward at the lower end portion of the mouth portion 3 is formed on the inner peripheral surface of the lower end portion of the peripheral wall portion 42. It is formed all around.

Next, the content pouring method using the pouring cap 1 configured as described above will be described.
First, the first spout 23A is opened. That is, the overcap 13 is removed, and the second extraction member 12 is released from the first extraction member 11 by further lifting the knob portion 31 </ b> A upward. Then, the ring portion 28 is pulled upward while the weakened portion 26 is broken while the finger is placed on the ring portion 28 of the pull ring portion 24, thereby breaking the weakening portion 26 together with the closing plate portion 25 together with the pull ring portion 24. 11 to separate. Thereby, the first spout 23A is opened.

  When it is desired to pour a large amount of contents at a time, the first pouring port 23A is exposed with the second pouring member 12 opened from the first pouring member 11. And the container 2 is inclined and a large amount of contents are poured out from the large diameter 1st spout 23A at once. Thereafter, when the contents are not to be poured out, the second pouring member 12 is attached to the first pouring member 11, and the overcap 13 is engaged with the flange portion 3 </ b> A of the mouth portion 3.

  Moreover, when it is desired to pour out a small amount of contents at a time, the second pouring member 12 is mounted on the first pouring member 11 to cover the first pouring port 23A. When the container 2 is tilted suddenly, the content flowing out from the first spout 23A is disposed between the first spout 23A and the second spout 37A. It cannot flow directly from the outlet 23 </ b> A into the dispensing cylinder part 37 and collides with the barrier part 34. As a result, the momentum of the contents flowing out from the first spout 23A is attenuated. The contents colliding with the barrier portion 34 flow into the extraction cylinder portion 37 through the communication port 35A so as to bypass the barrier portion 34. Then, the contents are poured out from the second pouring outlet 37A in a state where the momentum is attenuated.

When the container 2 is gently tilted, the contents flowing out from the first spout 23A flow along the inner surfaces of the inner cylinder portion 22 and the inner wall portion 32 and the lower surface of the top wall portion 33 and are poured. It flows into the outlet tube part 37 and is poured out from the second outlet 37A. Here, the top wall 33 is inclined so as to form a conical shape, and the contents are guided from the second spout 37A to guide the contents toward the dispensing cylinder 37 along the lower surface of the top wall 33. It becomes easy to pour out things. At this time, since a plurality of communication ports 35A are formed between the plurality of support portions 35, even if the contents flow from one of the plurality of communication ports 35A toward the extraction tube portion 37, the other The air can be supplied into the container 2 through the one communication port 35A.
The contents are poured out as described above. Thereafter, when the contents are not to be poured out, the overcap 13 is engaged with the flange portion 3 </ b> A of the mouth portion 3.

As mentioned above, according to the pouring cap 1 in this embodiment, even if the contents flow out vigorously from the first pouring port 23A by, for example, suddenly tilting the container 2, the content flowing out from the first pouring port 23A. Since the object collides with the barrier part 34 and does not flow directly into the dispensing cylinder part 37, the contents are prevented from flowing out from the second dispensing port 37A vigorously. Therefore, it is possible to more accurately control the dispensing amount by adjusting the flow rate of the contents from the second-diameter second outlet 37A.
Moreover, even if the barrier portion 34 and the support portion 35 are formed so as to protrude downward from the top wall portion 33 by disposing the barrier portion 34 inside the ring portion 28 of the pull ring portion 24, pouring is performed. The overall height of the cap 1 can be reduced.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, in the above-described actual embodiment, the barrier portion 34 has a flat plate shape as shown in FIGS. 1 and 2, but the barrier portion 34 ′ is radially inward as shown in FIGS. 3 and 4, for example. You may make the cone shape which inclines upwards as it goes to. In FIGS. 3 and 4, “′” is attached to the reference numerals of the members corresponding to those in FIGS. 1 and 2.
Thus, when the barrier portion 34 ′ is conical, when the contents are poured out from the second spout 37A ′, the container 2 ′ is returned to the inclined position and the container 2 ′ is brought into an upright posture. The inclined portion of the barrier portion 34 'guides the contents remaining in the dispensing cylinder portion 37' and returning to the container 2 'toward the communication port 35A'. Thereby, it can prevent that the contents are stored by the upper surface of barrier part 34 '.

In the above-described embodiment, the overcap 13 is formed as a separate member from the first and second dispensing members 11 and 12, but as shown in FIG. The first and second extraction members 11 ", 12" and the overcap 13 "may be formed as one component by being hinged to the knob portion 31A" of the second extraction member 12 "via 38". In FIG. 5, “” ”is given to the reference numerals of members corresponding to those in FIGS. 1 and 2. The second hinge portion 38 ″ is formed at a position opposite to the hinge portion 36 ″ that sandwiches the axis O in the radial direction in plan view. Further, a second knob portion 42B ″ projecting radially outward is formed at a position opposite to the second hinge portion 38 ″ that sandwiches the axis O in the radial direction at the lower end of the peripheral wall portion 42 ″.
In this way, the number of parts of the dispensing cap 1 ″ can be reduced by using the first and second dispensing members 11 ″, 12 ″ and the overcap 13 ″ as one component.

Further, in the above-described embodiment, the barrier portion 34 ′ has a plate shape. However, as shown in FIGS. 6 and 7, the barrier portion 34 ′ has a communication port 35A ′ corresponding to the communication port 35A ′. A guide portion 51 may be provided that extends downward from the lower end of the guide. The guide portion 51 is a plate member that is curved in an arc shape along the outer peripheral edge shape of the barrier portion 34 ′, and has a rectangular shape when the guide portion 51 is viewed from the outside in the radial direction. In addition, a plurality of guide portions 51 are arranged at equal intervals in the circumferential direction corresponding to the communication port 35A ′ at the outer peripheral edge of the barrier portion 34 ′. In addition, although the guide part 51 is provided independently with respect to each communication port 35A ', it may be connected mutually, for example in a disk shape.
Thus, by providing the guide part 51, when the container 2 ′ is in an upright posture after the content has been poured out, the content can reach the outer surface in the radial direction of the guide part 51 from the communication port 35 </ b> A ′. Since it is collected and collected at the lower end of the guide part 51, it becomes easy to become a droplet. Thereby, when the container 2 ′ is in the upright posture, the contents can be reliably collected in the container 2 ′. Moreover, it can suppress that the content adhering to barrier part 34 'dries and adheres to barrier part 34'.
Here, the shape of the guide portion is not limited to the rectangular shape described above, but may be a guide portion 51 ′ having a triangular shape when viewed from the outside in the radial direction, for example, as shown in FIGS. The width of the circumferential direction of the guide portion 51 ′ gradually decreases as it goes downward. As described above, since the width in the circumferential direction of the guide portion 51 ′ gradually decreases as it goes downward, the contents are collected at the lower end of the guide portion 51 ′, so that the liquid droplets are more easily formed. Thereby, the recoverability of the contents when the container 2 ′ is in the upright posture is further improved. The shape of the guide portion is not limited to a triangular shape as long as the circumferential width gradually decreases toward the bottom.
In addition, you may apply the guide parts 51 and 51 'to the extraction cap in other embodiment shown in FIG.1, FIG.2, FIG.5.

Furthermore, the barrier portion does not need to overlap with the entire second spout in a plan view, and only needs to overlap with at least a part of the second spout.
The support portion connects the peripheral edge portion of the barrier portion and the top wall portion, but the first outlet and the second outlet in the axial direction while securing a flow path between the first outlet and the second outlet. Other shapes and structures may be used as long as the barrier portion can be supported between the spout.
The barrier portion has a plate shape, but may have a shape other than the plate shape, and once the contents can be guided toward the first spout when the container is in an upright posture, The shape is not limited to a conical shape, such as a shape that is inclined downward or upward toward the other end.
The barrier portion is inserted on the radially inner side of the ring portion of the pull ring portion, but may be disposed at another position.
Ceiling wall portion is has a conical inclined upward toward the radially inner side, for example dome-shaped, etc. protruding upward shown in FIG. 3, may be another shape .
The first and second spouts are not limited to a circular shape in plan view, and may have other shapes.
The second pouring port is formed at the upper opening end of the pouring tube portion, but may have other configurations such as being formed directly on the top wall portion without providing the pouring tube portion.
A plurality of guide portions are provided corresponding to each of the plurality of communication ports, but may be provided corresponding to at least one communication port.

Moreover, as long as the internal diameter of a 2nd spout is a smaller diameter than a 1st spout, you may change suitably according to the viscosity of the content. For example, in the case of contents having a relatively high viscosity, if the second outlet is made smaller in diameter, after the contents are poured out from the second outlet by squeezing the container and increasing the internal pressure of the container, Since the contents can be sucked back from the second spout by lowering the internal pressure of the container by elastic recovery of the container, it is possible to improve liquid breakage.
In the case of contents having a relatively low viscosity, if the second outlet has a smaller diameter than the first outlet, but the diameter is larger, the container is inclined and the contents are poured out from the second outlet. Sometimes, the content is poured out and the air is supplied into the container (air replacement) smoothly, and the amount of water discharged from the second outlet can be accurately controlled.

  According to this invention, industrial applicability is recognized regarding the extraction cap which can be poured out by adjusting the flow rate of the contents from the second small diameter outlet.
