By the way, when the content liquid is discharged, it is not limited to the case where it is discharged in the form of bubbles, and there are times when it is desired to discharge the liquid as it is without forming bubbles. For example, in the case of removing stains from clothing, it is sometimes desired to discharge the detergent in foam form so that the detergent stays on the surface of the clothing for a long time. Sometimes. In the case of food seasoning (such as soy sauce), the food may be sprinkled in a liquid state, or in order to reduce the amount used, it may be foamed and discharged so as to be placed on the food. Furthermore, in the case of beverages such as beer and coffee, there is also a demand to discharge foam onto the surface of the liquid after pouring the liquid into a glass or the like. However, the discharge containers shown in Patent Documents 1 and 2 cannot discharge the content liquid in a liquid state. It is necessary to prepare another container that can be discharged as it is.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a discharge container capable of discharging a content liquid contained in a container body in a liquid state or in a foam state. and

a tubular pipe having a bottom side opening located on the bottom side and a mouth side opening located on the mouth side;
a cap body that is attached to the mouth and has a top wall that holds the pipe and has a communication port that communicates with the mouth-side opening and a discharge port that communicates with the housing space;
a top wall which is detachably attached to the cap body, communicates the outlet with the outside when the lid is open, and shields the outlet from the outside when the top wall is closed when the lid is closed; a connecting member that separates from the communication port when the lid is closed, and has one end connected to the communication port when the lid is closed, and a discharge port provided at the other end communicates with the communication port; , and
By tilting the container body with the lid open, the liquid content in the accommodation space is discharged from the discharge port to the outside, and the container body is shaken to foam the content liquid and the lid body. By compressing the barrel portion while tilting the container body with the lid closed, the foamed content liquid is introduced from the bottom side opening and discharged to the outside from the discharge port. ,
The lid body is a discharge container having a check valve on the downstream side of the discharge port, which normally closes and opens when the storage space is pressurized by squeezing the barrel.
Further, in the present invention, a mouth part with an open top, a flexible body part connected to the mouth part, and a bottom part connected to the body part form a cylindrical shape with a bottom, and a storage space for containing the liquid inside. a container body having
a tubular pipe having a bottom side opening located on the bottom side and a mouth side opening located on the mouth side;
a cap body that is attached to the mouth and has a top wall that holds the pipe and has a communication port that communicates with the mouth-side opening and a discharge port that communicates with the housing space;
a top wall which is detachably attached to the cap body, communicates the outlet with the outside when the lid is open, and shields the outlet from the outside when the top wall is closed when the lid is closed; a connecting member that separates from the communication port when the lid is closed, and has one end connected to the communication port when the lid is closed, and a discharge port provided at the other end communicates with the communication port; , and
By tilting the container body with the lid open, the liquid content in the accommodation space is discharged from the discharge port to the outside, and the container body is shaken to foam the content liquid and the lid body. By compressing the barrel portion while tilting the container body with the lid closed, the foamed content liquid is introduced from the bottom side opening and discharged to the outside from the discharge port. ,
The connecting member includes a second check valve that closes and opens the communication port, and a second communication port that is provided separately from the communication port and communicates the storage space and the discharge port. and
When outside air is taken in from the discharge port as the compressed body recovers with the lid closed, the communication port is closed by the second check valve, while the discharge port is closed. The discharge container is also configured such that outside air taken in through the outlet is introduced into the accommodation space through the second communication port.

Furthermore, it is preferable to provide an outer lid detachably attached to the lid member so as to cover the discharge port.

It is preferable to provide a first hinge that integrally connects the cap main body and the lid, and a second hinge that integrally connects the lid and the outer lid.

It is preferable that the lid has a foam member on the upstream side of the discharge port.

It is preferable to provide a mesh member on a path from the second communication port to the accommodation space.

According to the discharge container of the present invention having such a configuration, when the content liquid is to be discharged in a liquid state, the contained content liquid can be turned into a liquid state by tilting the container main body with the lid opened. It can be discharged from the discharge port as it is. In addition, when the content liquid is to be discharged in the form of foam, the container body is shaken to foam the content liquid, and then, with the lid closed, the container body is tilted and the barrel is squeezed. The content liquid foamed in the housing space can be discharged from the discharge port through the bottom side opening.

In addition, when an outer lid that covers the ejection port and is detachably attached to the lid is provided, the ejection port does not remain exposed during storage, so the content liquid adhering to the ejection port may not solidify. , it is possible to prevent problems such as adhesion of dust or the like to the ejection port.

For example, the lid and the outer lid may be separate members that can be detachably attached using screws or the like. When a hinge and a second hinge for integrally connecting the lid body and the outer lid are provided, the cap main body, the lid body, and the outer lid can be formed by one member. Also, if these are different members, it is necessary to secure a place for the open outer lid and lid body, but when providing the first hinge and the second hinge, you can use it without worrying about the place. can. Moreover, since the first hinge and the second hinge are provided, the outer lid and the lid body can be opened even with one hand, so that the usability is excellent.

Further, when a foaming member is provided on the lid on the upstream side of the discharge port, the content liquid formed into foam by shaking the container body can be discharged in finer foam.

If a check valve is provided on the lid downstream of the discharge port, which normally closes and opens when the storage space is pressurized due to the compression of the body, the liquid is discharged in a foamy state. In addition, it is possible to effectively prevent the content liquid remaining in the ejection port from dripping.

Further, in the case where the connecting member is provided with the second check valve and the second communication port as described above, the outside air taken in from the discharge port is restored when the body after compression is restored with the lid closed. is introduced into the housing space through the second communication port without passing through the communication port leading to the pipe. That is, when outside air is introduced into the housing space and passes through the pipe, the foamy content liquid remaining in the pipe is returned to the housing space. Although the liquid may not be discharged immediately, if the outside air is introduced into the housing space from the second communication port, the foamy content liquid can be discharged immediately when the body is next squeezed. .

In providing the second communication port, when the container body is tilted with the lid closed to discharge the foamy content liquid, the content liquid in the accommodation space flows toward the second communication port. If the body is squeezed in this state, in addition to the foamy liquid content that is fed from the bottom side opening to the discharge port, there is a possibility that the liquid content liquid will be fed from the second communication port to the discharge port. be. Here, when a mesh member is provided in the path from the second communication port to the accommodation space, the mesh member acts as a resistance and makes it difficult for the liquid content to flow into the second communication port. can be discharged.

The second hinge 10c is provided on the opposite side of the central axis O from the first hinge 4c. A claw portion (outer lid inward claw portion) 10d that engages with the lid body outward claw portion 4h is provided at the lower end portion of the inner surface of the outer lid outer peripheral wall 10a. The outer lid 10 can be kept closed with respect to the lid body 4 by engaging with the lid inward claw portion 10d. Further, the outer lid outer peripheral wall 10a has a knob portion 10e on the opposite side of the second hinge 10c across the central axis O. As shown in FIG. A seal annular wall 10f is provided on the lower surface of the lid wall 10b so as to surround the slit valve 8 and abut against the upper end of the top wall 4b when the outer lid 10 is closed.

In discharging the content liquid from the discharge container having such a structure, as shown in FIG. Open the lid. When the container main body 1 is tilted, the liquid contained in the housing space S flows toward the mouth portion 1c, passes through the discharge port 2e, and is discharged along the pouring cylinder 2f.

When the content liquid is discharged from the discharge container in the form of foam, the container body 1 is shaken with the lid 4 and the outer lid 10 closed to foam the content liquid in the storage space S. As shown in FIG. Then, as shown in FIG. 4, the outer lid 10 is opened with respect to the lid body 4 by swinging about the second hinge 10c. Then, while tilting the container body 1, the body portion 1b is squeezed. Here, when the container body 1 is tilted as shown, the liquid content in the accommodation space S flows toward the mouth portion 1c, while the foamed content liquid accumulates around the bottom portion 1a. Therefore, when the storage space S is pressurized by squeezing the body portion 1b, the foamed content liquid passes through the inside of the pipe 3 from the bottom side opening 3a and further passes between the connecting cylinder portion 5c and the moving valve 6. It passes through the foam member 7 and the discharge port 5g, and is discharged to the outside while elastically deforming the valve body 8a toward the outside.

Since the container body 1 is tilted, the liquid in the storage space S passes through the discharge port 2e and moves to the periphery of the connecting member 5, but the pouring tube 2f is liquid-tight with the sealing wall 4f. , the content liquid does not leak to the outside. In addition, although the connecting member 5 is provided with the second communication port 5e, the mesh member 9 is provided upstream of the second communication port 5e. will create resistance. For this reason, the foamy content liquid passing through the inside of the pipe 3 flows more easily than the liquid content liquid passing through the second communication port 5e, so that the foamy content liquid can be preferentially discharged. .

In addition, it is possible to discharge the foam-like content liquid accumulated in the bottom portion 1a without providing the foaming member 7, but by providing the foaming member 7 as in the present embodiment, the foam can be made to have a finer texture. can be ejected.

When the pressure on the body portion 1b is released, the valve main body 8a, which has been elastically deformed by the pressurized foamy content liquid, returns to its original state as shown in FIG. discharge of the content liquid can be immediately stopped. Further, when the force of the hand pressing the trunk portion 1b is relaxed, the volume of the accommodation space S increases as the flexible trunk portion 1b is restored, so the accommodation space S is decompressed. Therefore, outside air enters through the slit of the valve body 8a, passes through the discharge port 5g and the foam member 7, and is introduced into the connecting member 5. As shown in FIG. It should be noted that the moving valve 6 is seated on the connecting tube portion 5 c by outside air introduced inside the connecting member 5 . That is, outside air is introduced into the housing space S through the second communication port 5e without flowing toward the pipe 3. As shown in FIG. Since new outside air is introduced into the accommodation space S in this manner, the content liquid can be newly foamed by shaking the container body 1 again.

In the discharge container according to the present invention, the moving valve 6 can be omitted. It may be returned to the accommodation space S, and the foamy content liquid may not be discharged immediately even if the body portion 1b is squeezed next time. On the other hand, when the movable valve 6 is provided as in the present embodiment, there is an advantage that the foamy content liquid can be discharged immediately when the body portion 1b is next compressed.

Although the discharge container according to the present invention has been described above while showing specific embodiments, the discharge container according to the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. Also included. For example, in this embodiment, the moving valve 6, the foaming member 7, the slit valve 8, and the mesh member 9 are provided. It is possible. In this embodiment, the first hinge 4c and the second hinge 10c are provided to integrally form the cap body 2, the lid 4, and the outer lid 10. However, the first hinge 4c and the second hinge 10c are not provided. Alternatively, they may be separated and formed individually.
