  However, in the configuration of Patent Document 2 described above, the amount to be dispensed can be selectively switched by switching the two spouts, but for example, the contents are poured out as they are or discharged as foam. For example, it is not possible to switch the manner in which the content is poured out from the spout. If the foamed member as in Patent Document 1 is applied as it is to the configuration of Patent Document 2, the structure may be complicated. That is, in the conventional configuration, there is room for improvement in that the configuration is such that the content dispensing mode can be switched with a simple configuration.

  This invention is made | formed in view of such a situation, Comprising: It aims at providing the cap which can switch an extraction aspect, after simplifying a structure.

In order to solve the above problems, the present invention proposes the following means.
The cap according to the present invention is attached to the mouth of the container body, and has a cap body having a communication hole that communicates the inside and the outside of the container body, and a gas-liquid mixture of contents and gas that have passed through the communication hole. the a foamed member of foaming, and a spout communicating with the communication hole through said foam member, and a foamed portion that is pivotally connected via a hinge portion to said cap body, said foam The portion rotates between a mounting state in which the spout communicates with the communication hole via the foam member and a state in which the communication hole is exposed, and the cap body communicates with the communication hole. In addition, a content communication part through which the contents in the container body circulate, a gas communication part through which the gas in the container body circulates, and a pouring posture in which the communication hole is directed downwards. When you move, the ream An opening / closing valve that shuts off communication between the hole and the gas communication part, the content communication part and the gas communication part are provided independently of each other, and the cap body or the foaming part is when previously in KiSo deposition states, and was the dispensing position, to restrict the movement of the on-off valve, as characterized in that it comprises a valve regulating portion for providing communication between said communication hole said gas communication portion Yes.

With such a feature, it is possible to switch between the restriction of the on-off valve and the release of the restriction by the valve restriction part by switching the attachment / detachment state between the foaming part and the cap body.
That is, when the foaming portion is in the mounted state and the cap is in the pouring posture with the spout of the foaming portion exposed, the movement of the on-off valve is regulated by the valve regulating portion, so that the gas communicating portion and the communicating hole Communicate. Then, after the content flowing through the content communication portion and the gas flowing through the gas communication portion pass through the communication hole and are foamed by the foamed member, the foam is poured out from the spout ( Foam mode).
On the other hand, since the restriction of the on / off valve by the valve restricting part is released by exposing the communication hole with the foamed part removed from the cap body, when the cap is in the pouring posture, the gas communication is performed by the on / off valve. The communication between the part and the communication hole is blocked. Thereby, only the content which distribute | circulates the content communication part is poured out collectively from a communicating hole (straight liquid mode).
Therefore, the dispensing mode can be switched after the configuration is simplified.
Moreover, according to the structure of this invention, it can suppress that a foam adheres in a cap main body by attaching / detaching the foaming part which has a foaming member with respect to a cap main body. Thereby, in the direct liquid mode mentioned above, it can suppress that a foam is poured out from a communicating hole.

Further, in the cap body, a portion of the cap body located between the communication hole and the gas communication portion is provided with a valve storage portion in which the open / close valve is movably stored, You may restrict | limit the movement of the said on-off valve when it approachs in the said valve accommodating part in the mounting state, and is set as the said pouring attitude | position.
According to this configuration, since the valve restricting portion enters the valve housing portion in the mounted state of the foaming portion, the movement of the on-off valve during the pouring posture can be reliably restricted. Thereby, according to attachment / detachment operation of a foaming part, the extraction aspect can be switched reliably.

  With the cap according to the present invention, the dispensing mode can be switched after simplifying the configuration.

A gas supply pipe 52 is fitted into the ball receiver 51 from below. The gas supply pipe 52 has a cylindrical shape that extends to a position close to the bottom (not shown) of the container body 11. The gas supply pipe 52 is configured to open into a space (air space) formed on the bottom side of the container body 11 when the dispensing container 1 is tilted to a dispensing posture in which the cap 12 faces downward. . The flow path member 41, the ball receiver 51, and the gas supply pipe 52 communicate with the communication hole 34 and constitute a gas communication part S <b> 2 through which the gas in the container body 11 flows. In this case, the content communication portion S1 and the gas communication portion S2 are provided independently of each other, and merge before the communication hole 34 in the cap body 21 (below the inner flange portion 38).

  Here, in the cap main body 21, a valve accommodating portion 54 that accommodates an on-off valve 53 described later is configured at a portion located between the communication hole 34 and the gas communication portion S <b> 2. The valve accommodating portion 54 is defined by a lower inner surface of the protruding cylinder portion 44 in the flow path member 41 and an upper inner surface of the ball receiver 51, and an upper end opening communicates with the communication hole 34 through the protruding cylinder portion 44.

The seal surfaces 51a and 44a are configured.

  The on-off valve 53 is a sphere, and is movable in the valve accommodating portion 54 by its own weight, for example. That is, the on-off valve 53 is configured to be seated or separated from the projecting cylinder portion 44 and the seal surfaces 51a, 44a of the ball receiver 51, and switches between communication and blocking between the communication hole 34 and the gas communication portion S2. ing. In the upright posture of the dispensing container 1 (the cap 12 is facing upward and the bottom of the container body 11 is facing downward), the on-off valve 53 is seated on the seal surface 51a of the ball receiver 51 and the lower end opening of the valve accommodating part 54 is opened. The portion is closed, and communication between the gas communication portion S2 and the communication hole 34 is blocked. As a result, it is difficult for the contents to flow into the gas supply pipe 52 in the upright posture of the dispensing container 1.

The foaming part 23 includes an outer cylinder part 61 and an inner cylinder part 62, an extraction cylinder 63 provided continuously from the upper end edge of the inner cylinder part 62, and a foaming member 68 assembled in the inner cylinder part 62. ing.
The outer cylinder part 61 is integrally connected to the upper end part of the cap body 21 through the first hinge part 22 described above at the lower end part in the circumferential direction. Thereby, the foaming part 23 can open and close the cap main body 21 around the first hinge part 22. Moreover, the outer cylinder part 61 is detachably fitted to the lower cylinder part 36 in the cap body 21 according to the opening / closing operation of the foaming part 23.

Specifically, the dispensing cylinder 63 is tapered so as to gradually decrease in diameter as it goes upward, and its upper end opening constitutes the dispensing outlet 63a of the foaming portion 23.

The foam member 68 includes a cylindrical mesh receiver 71 fitted into the inner cylinder portion 62 from below, and a mesh ring 72 fitted into the mesh receiver 71.
The mesh receiver 71 has a length along the container axis O direction that is longer than the inner cylinder portion 62 described above, and a lower end portion of the mesh receiver 71 projects downward from a lower end edge of the inner cylinder portion 62. And the lower end part (the part which protruded below the inner cylinder part 62 among the mesh receivers 71) of the mesh receiver 71 is attached to and detached from the upper cylinder part 37 of the cap main body 21 according to the opening / closing operation of the foam part 23. It can be fitted.
The mesh ring 72 has a cylindrical shape extending along the container axis O direction, and a mesh sheet 73 covering the mesh ring 72 from above is stretched on the upper end opening edge.

  Here, in the mesh receiver 71, a rod-shaped valve restricting portion 75 arranged coaxially with the mesh receiver 71, and the valve restricting portion 75 and the mesh receiver 71 are connected to a portion located below the mesh ring 72. The connecting portion 76 is integrally formed with the mesh receiver 71.

The valve restricting portion 75 is configured to be able to advance and retreat into the valve accommodating portion 54 through the communication hole 34 according to the opening / closing operation of the foaming portion 23. Specifically, when the foaming portion 23 is in the closed position (mounted state attached to the cap body 21), the valve restricting portion 75 enters the valve accommodating portion 54 through the communication hole 34 described above, and the open / close valve The movement of 53 toward the communication hole 34 along the container axis O direction is restricted. On the other hand, the valve restricting portion 75 retracts from the valve accommodating portion 54 when the foaming portion 23 shown in FIG. 2 is in the open position, and allows the opening / closing valve 53 to move toward the communication hole 34 along the container axis O direction. ing.
The connecting portion 76 extends radially from the upper end portion of the valve restricting portion 75, and the outer peripheral edge thereof is connected to the inner peripheral surface of the mesh receiver 71.

Yes. Accordingly, the overcap 25 can open and close the dispensing cylinder 63 around the second hinge portion 24. Further, the peripheral wall portion 81 is detachably fitted to the upper projecting portion of the inner cylindrical portion 62 in the foam portion 23 in accordance with the opening / closing operation of the overcap 25. Note that the second hinge portion 24 is formed at the same position in the circumferential direction as the first operation piece 64 described above.

  A plug cylinder 83 protrudes downward from the top wall portion 82. When the plug cylinder 83 is fitted into the extraction cylinder 63, the extraction cylinder 63 is closed. Further, a second operation piece 84 is extended upward on the top wall portion 82.

Next, the operation of the dispensing container 1 having the cap 12 described above will be described. In the following description, the initial state is a state in which the dispensing container 1 is in the upright posture and both the foaming portion 23 and the overcap 25 are in the closed position.
First, the direct liquid mode will be described.
First, in a state where the container body 11 in the initial state is gripped, the foamed portion 23 is opened together with the overcap 25, and the communication hole 34 of the cap body 21 is exposed. Specifically, as shown in FIG. 2, by placing a finger or the like on the first operation piece 64 and pulling up the first operation piece 64, the foamed portion 23 rotates around the first hinge portion 22 together with the overcap 25. Move. Thereby, the communication hole 34 of the cap main body 21 is exposed.

  And the pouring container 1 is inclined to the pouring attitude | position which the cap 12 (communication hole 34) faces downward, and the bottom part of the container main body 11 faces upward. Then, the on-off valve 53 is moved away from the seal surface 51 a of the ball receiver 51 by moving downward in the valve housing portion 54 (on the side of the communication hole 34) by its own weight, and thereafter the seal of the projecting cylinder portion 44. Sitting on the surface 44a. Thereby, the communication between the communication hole 34 and the gas communication portion S2 is blocked.

  In this state, the container body 11 is squeezed to reduce the volume of the container body 11. Then, the pressure in the container body 11 becomes a positive pressure with the volume reduction deformation, and the contents are poured out from the communication hole 34 by this positive pressure (solid arrow in FIG. 2). Specifically, the content in the container body 11 flows into the content communication portion S1 through the through hole 43 of the flow path member 41. The contents flowing into the content communication part S1 reach the communication hole 34 through the content communication part S1, and are poured out from the communication hole 34 to the outside. At this time, since the communication between the gas communication portion S2 and the communication hole 34 is blocked by the on-off valve 53 as described above, no gas flows out from the communication hole 34. Therefore, the contents are poured out from the communication hole 34 in a state of being collected.

Next, the foam mode will be described.
First, in a state where the container body 11 in the initial state shown in FIG. 1 is gripped, only the overcap 25 is opened, and the dispensing cylinder 63 of the foaming portion 23 is exposed. Specifically, as shown in FIG. 3, the overcap 25 rotates around the second hinge portion 24 by placing a finger or the like on the second operation piece 84 and pulling down the second operation piece 84. Thereby, the extraction cylinder 63 of the foaming part 23 is exposed.

  As in the direct liquid mode described above, when the pouring container 1 is in the pouring posture, the on-off valve 53 moves downward in the valve housing portion 54 by its own weight, so that the ball receiver 51 is sealed. It separates from the surface 51a. At this time, the valve restricting portion 75 enters the valve accommodating portion 54 into the valve accommodating portion 54 through the communication hole 34 described above. Therefore, the on-off valve 53 separated from the seal surface 51 a of the ball receiver 51 abuts against the valve restricting portion 75 before sitting on the seal surface 44 a of the projecting cylinder portion 44. Thereby, since the movement of the on-off valve 53 is restricted, the on-off valve 53 is separated from the seal surfaces 51 a and 44 a of the ball receiver 51 and the protruding cylinder portion 44. Thereby, the gas communication part S <b> 2 and the communication hole 34 communicate with each other through the valve housing part 54.

  In this state, when the container main body 11 is squeezed and the volume of the container main body 11 is reduced, the contents in the container main body 11 flow into the content communicating portion S1 through the through hole 43 of the flow path member 41. (Solid arrow in FIG. 3), the gas in the container body 11 (in the air space) flows from the gas supply pipe 52 into the gas communication part S2 (broken arrow in FIG. 3). And the contents which flowed in in contents communication part S1, and the gas which flowed in in gas communication part S2 merge before the communicating hole 34 in cap body 21, and the contents and gas were mixed. It becomes a gas-liquid mixture. Thereafter, the gas-liquid mixture flows into the mesh ring 72 through the communication hole 34 and between the connecting portions 76 of the mesh receiver 71. And a gas-liquid mixture turns into the foamed foam by passing the mesh sheet | seat 73, and is poured out from the spout 63a.

Thus, according to the present embodiment, since the foaming portion 23 includes the valve restricting portion 75, the valve position can be changed by switching the opening / closing position of the foaming portion 23 (the attachment / detachment state between the foaming portion 23 and the cap body 21). The restriction of the on-off valve 53 by the restriction part 75 and the release of the restriction can be switched. Thereby, it is possible to switch the content dispensing mode between the direct liquid mode and the foam mode with a simple configuration.
Further, by opening / closing the foamed portion 23 having the foamed member 68 with respect to the cap main body 21, it is possible to suppress the foam from adhering to the cap main body 21. Thereby, it can suppress that a foam is poured out from the communicating hole 34 in the direct liquid mode mentioned above.

Further, since the valve restricting portion 75 enters the valve accommodating portion 54 at the closed position of the foaming portion 23, the movement of the on-off valve 53 during the pouring posture can be reliably restricted. Thereby, according to attachment / detachment operation of the foaming part 23, the extraction | pouring aspect can be switched reliably.
In addition, since the on-off valve 53 is a sphere, the on-off valve 53 moves smoothly according to the attitude of the container body 11, so that the communication between the gas communication portion S2 and the communication hole 34 can be switched reliably. be able to.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.

The surrounding cylinder 122 is detachably fitted to the guide cylinder 102 of the cap body 101 in accordance with the opening / closing operation of the foaming portion 110.
On the other hand, a rod-shaped operation protrusion 123 extending downward is formed on a portion of the bottom wall portion 115 located radially inside the through-hole 121 (a central portion of the bottom wall portion 115). . The operation protrusion 123 is formed with a locking protrusion 123a that protrudes outward in the radial direction, and is detachably locked in the slide cylinder 103 according to the opening / closing operation of the foaming section 110. Yes. Further, a groove 123b extending along the container axis O direction is formed in the operation protrusion 123 with a gap in the circumferential direction. These groove portions 123b are recessed toward the inside in the radial direction, and are formed over the entire operation projection 123 along the container axis O direction. When the foaming portion 110 is in the closed position, the operation projection 123 is locked in the slide cylinder 103 and restricts the upward movement of the slide cylinder 103.

In the cap 100 configured as described above, in the direct liquid mode shown in FIG. 5, the foamed portion 110 is set to the open position together with the overcap 25 while the first operation piece 64 is first gripped. At this time, the foaming part 110 rotates around the first hinge part 22, so that the slide cylinder 103 locked to the operation protrusion 123 slides upward in the guide cylinder 102 together with the operation protrusion 123. . As a result, the valve restricting portion 104 of the slide cylinder 103 is retracted from the valve accommodating portion 54.
Thereafter, the foaming portion 110 is further rotated to release the engagement between the operation projection 123 and the slide cylinder 103, and the communication hole 103a of the slide cylinder 103 is exposed.

  Subsequently, when the pouring container 150 is in the pouring posture, the on-off valve 53 in the valve accommodating portion 54 moves downward (toward the communication hole 103a) by its own weight, so that the seal surface 107a of the ball receiver 107 is moved. After separating, it is seated on the sealing surface 105a of the flow path member 105. Thereby, the communication between the communication hole 103a and the gas communication part S2 is blocked.

  In this state, when the container main body 11 is squeezed and deformed, the contents in the container main body 11 flow into the contents communicating portion S1 through the recess 106 of the flow path member 105 (solid arrow in FIG. 5). The content that has flowed into the content communication portion S1 flows into the slide cylinder 103 through the content communication portion S1, and is then poured out from the communication hole 103a. At this time, since the communication between the gas communication portion S2 and the communication hole 103a is blocked by the on-off valve 53 as described above, no gas flows out from the communication hole 103a. Therefore, the contents are poured out from the communication hole 103a in a state of being collected.

  On the other hand, in the foam mode shown in FIG. 6, first, the second operation piece 84 is pulled down to set only the overcap 25 to the open position. Similarly to the direct liquid mode described above, when the pouring container 150 is in the pouring posture, the on-off valve 53 in the valve housing portion 54 moves downward due to its own weight, so that the seal surface of the ball receiver 107 is Separate from 107a. Here, when the foaming part 110 is in the closed position, the movement of the slide cylinder 103 in the direction of the container axis O is restricted by the operation projection 123 with the valve restricting part 104 entering the valve accommodating part 54. . Therefore, the on-off valve 53 separated from the seal surface 107 a of the ball receiver 107 abuts against the valve restricting portion 104 before sitting on the seal surface 105 a of the flow path member 105. As a result, the gas communication portion S2 and the communication hole 103a communicate with each other through the valve housing portion 54.

  When the container main body 11 is squeezed and deformed in this state, the contents in the container main body 11 flow into the slide cylinder 103 through the content communication portion S1 (solid arrow in FIG. 6), and in the container main body 11 Gas flows from the gas supply pipe 52 into the gas communication part S2 (broken line arrow in FIG. 6). The contents that have flowed into the content communication portion S1 and the gas that has flowed into the gas communication portion S2 join together in the slide tube 103, and thereby flow through the slide tube 103 as a gas-liquid mixture. . Thereafter, the gas-liquid mixture passes through the communication hole 103 a through the groove 123 b of the operation protrusion 123. The gas-liquid mixture that has passed through the communication hole 103 a flows into the mesh ring 72 through the through-hole 121 of the mesh receiver 113, and then becomes a foamed foam by passing through the mesh sheet 73. It is poured out from 63a.

  Also in this configuration, since the foaming part 110 includes the operation protrusion 123, the opening / closing position of the foaming part 110 can be switched to switch the restriction of the opening / closing valve 53 by the operation protrusion 123 and the release of the restriction.

  In addition, in the range which does not deviate from the meaning of this invention, it is possible to replace suitably the component in the embodiment mentioned above by the known component, and you may combine the modification mentioned above suitably.
