Description

  The present invention relates to a dispensing container including a container main body having a storage space for storing the content liquid, and an extraction cap that has an opening for pouring the content liquid and is attached to the container main body.

  For containers that contain cosmetics such as hair-growing agents and various chemicals, etc. as content liquids, there are known extraction containers with an extraction cap having an opening for extracting the content liquid attached to the container body. ing. As such a dispensing container, for example, in Patent Document 1, a hook-shaped member is sandwiched and held between the mouth-neck portion of the container body and the palate, and a valve ball is accommodated inside the hook-shaped member. In addition, a dispensing container with a valve function is shown in which a nozzle is fitted in a guide cylinder of the palate so as to be movable up and down. In such a dispensing container, when the container body is displaced from the upright position to the inverted position, the nozzle protrudes from the upper surface of the palate and the valve ball closes the lower end opening of the guide tube. When the nozzle is pressed against the coating surface and the nozzle is pushed into the guide cylinder, the blocking function by the valve ball is released, and the content liquid is discharged through the nozzle, so it can be used easily without getting your hands dirty. be able to.

Japanese Utility Model Publication No. 3-69663

  However, this type of dispensing container has a time lag between the time when the valve body closes the guide cylinder after the container body is displaced to the inverted position when the nozzle is applied to the site where the content liquid is to be dispensed. The content liquid may leak out. For this reason, for example, when it is desired to apply to the head but to adhere to the face, or to apply to the arm but to the clothes, the content liquid may adhere to an unintended part. In addition, since the content liquid continues to be poured out while the container body is placed in an inverted posture and pressed against the application surface, the content liquid may be excessively poured out even after application to the intended site.

  The present invention provides a dispensing container capable of solving the above-described problems of the prior art, preventing dripping of the content liquid to an unintended part, and preventing excessive dispensing of the content liquid. With the goal.

  The dispensing container according to the present invention has a trunk portion connected to the bottom portion and a mouth portion connected to the trunk portion, and includes a housing space for containing the content liquid inside the bottom portion, the trunk portion, and the mouth portion. A container body, a top wall having an opening for pouring the content liquid, a pouring cap attached to the mouth, and a communication that is held by the pouring cap in the housing space and communicates with the opening A holder having a partition having an inner space for containing the content liquid that has passed through the communication port, and a valve body provided with a protrusion protruding from the opening; Normally, the valve body abuts on the top wall to close the opening, and when the projection is pressed, the opening is opened and the valve body abuts on the partition wall to connect the communication port. And a check valve that closes the valve.

  In the dispensing container of the present invention, the communication port is composed of at least a first communication port and a second communication port, and the first communication port is more than the second communication port. It is preferable that the opening area is small.

  Furthermore, in the dispensing container of the present invention, it is preferable that the first communication port is located on the bottom side with respect to the second communication port.

  In the dispensing container of the present invention, the dispensing cap has a curved wall that surrounds the opening, and the projection can be pushed and rotated by the curved wall inside the curved wall. It is preferable to provide a supported spherical body.

  The dispensing container according to the present invention has a communicating port that is held by the dispensing cap in the accommodation space and communicates with the opening of the dispensing cap, and stores the content liquid that has passed through the communicating port between the top wall of the dispensing cap. A holder with a partition wall having a space and a valve body provided with a protrusion protruding from the opening and provided in the internal space, the valve body normally contacts the top wall to close the opening, A check valve is provided that opens the opening when pressed and the valve body abuts against the partition wall to close the communication port. For this reason, even if the container main body is displaced to the inverted posture, the content liquid does not leak from the opening, so that the content liquid can be prevented from dripping to an unintended part. Since the opening is opened only when the protrusion is pressed, if the container body is lifted after pouring out the contents liquid, the dispensing of the contents liquid can be stopped even if the container body is in an inverted posture. it can. For this reason, excessive dispensing of the content liquid can be prevented.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view of a dispensing container according to an embodiment of the present invention in a side view, and FIG. 2 (a) is a cross-sectional view along the line AA shown in FIG. 2 (b) is a cross-sectional view taken along line BB shown in FIG. 1, and FIG. 2 (c) is an arrow view of the holder along arrow C shown in FIG. 3A is a plan view of the check valve shown in FIG. 1, and FIG. 3B is a half sectional view of the check valve in a side view.

  As shown in FIG. 1, the dispensing container mainly includes a container body 1, a dispensing cap 2, a holder 3, a check valve 4, and a spherical body 5.

  The container body 1 has a disk-shaped bottom portion (not shown), a cylindrical body portion 1a that rises from the outer periphery of the bottom portion, and a cylindrical mouth that is connected to the upper end of the body portion 1a and has a smaller diameter than the body portion 1a. And a convex portion 1c is formed on the outer peripheral surface of the mouth portion 1b. In addition, a storage space M for storing the content liquid is formed inside the bottom portion, the body portion 1a, and the mouth portion 1b.

  The dispensing cap 2 includes a base portion 2b having a claw portion 2a that surrounds the upper end and the outer peripheral surface of the mouth portion 1b and engages with the convex portion 1c on the inner peripheral surface thereof. Inside the base portion 2b, a ceiling wall 2c that is curved so as to protrude downward is provided. In the top wall 2c, for example, a total of four openings 2d penetrating the top wall 2c are provided at regular intervals as shown in FIG. Further, as shown in FIG. 1, a curved wall 2e is provided on the top surface of the top wall 2c so as to surround the opening 2d and bend with the same curvature as the top wall 2c. The lower surface of the top wall 2c is provided with a bulging portion 2f that bulges downward at the center thereof, and a claw-like engagement wall 2g for holding the holder 3 is provided outside the opening 2d. Yes. Further, a seal wall 2h that is in liquid-tight contact with the inner peripheral surface of the mouth portion 1b is provided on the radially outer side of the engagement wall 2g on the lower surface of the top wall 2c.

  The holder 3 includes an annular wall 3a that is engaged and held by the engagement wall 2g. A partition wall 3b is provided at the lower end of the annular wall 3a so as to extend inclined toward the bottom of the container body 1. In the state where the holder 3 is attached to the dispensing cap 2, an internal space N is formed between the top wall 2c and the partition wall 3b. The partition wall 3b is provided with a communication port that penetrates the partition wall 3b. There may be at least one communication port, but in this embodiment, two communication ports (first communication port 3c and second communication port 3d) are provided. Here, the first communication port 3c is located closer to the bottom side of the container body 1 than the second communication port 3d, and has an opening area larger than that of the second communication port 3d as shown in FIG. It is a small one. A cylindrical wall 3e surrounding the first communication port 3c is provided on the lower surface of the partition wall 3b, and an inner annular wall 3f whose upper ends are aligned at the same height is provided at the center of the upper surface of the partition wall 3b. Yes.

  As shown in FIG. 3A, the check valve 4 has a disk shape as a whole. When the check valve 4 is assembled to the dispensing cap 2 and the holder 3, the outer edge portion 4a thereof is shown in FIG. As shown, it is sandwiched between the pouring cap 2 and the holder 3. As shown in FIG. 3 (a), a donut plate-like valve body 4c having a hole 4b in the center is provided inside the outer edge portion 4a. A protrusion 4d is formed on the upper surface of the valve body 4c. Four are provided at equal intervals. Here, the valve body 4c is in contact with the lower surface of the top wall 2c in a state in which the bulging portion 2f protrudes from the hole 4b in the state assembled to the pouring cap 2 and the holder 3 as shown in FIG. Further, the protrusion 4d protrudes from the opening 2d. The check valve 4 is made of a relatively soft material such as rubber, elastomer, or low density polyethylene (LDPE), and the valve body 4c swings up and down from the outer edge 4a. It is possible to operate.

  The spherical body 5 is disposed on the inner side of the top wall 2c and the curved wall 2e, and is held on the curved wall 2e in a state of being in contact with the protrusion 4d. Note that a slight gap is provided between the top wall 2c and the curved wall 2e and the spherical body 5, and the spherical body 5 is movable in the vertical direction. And can be rotated.

  When the content liquid is poured out from the dispensing container of this embodiment, first, the container body 1 is displaced to the inverted posture as shown in FIG. As a result, the content liquid in the storage space M moves toward the holder 3. Here, the holder 3 is provided with the first communication port 3c and the second communication port 3d, but the content liquid passes through the second communication port 3d having a larger opening area than the first communication port 3c. Therefore, it is preferentially introduced into the internal space N from the second communication port 3d. On the other hand, since air accumulated in the internal space N is discharged from the first communication port 3c, both can be reliably replaced in the internal space N. Further, in this embodiment, since the first communication port 3c is located on the bottom side of the container body 1 with respect to the second communication port 3d, the liquid having a large specific gravity collects in the second communication port 3d, while the specific gravity The small air gathers at the first communication port 3c, and the replacement of the content liquid and air in the internal space N is more reliably performed. Further, in this embodiment, since the first communication port 3c is surrounded by the cylindrical wall 3e, the second communication port 3d is introduced into the internal space N in the second communication port 3d rather than the first communication port 3c. , Even more preferential. In this state, the valve body 4c comes into contact with the lower surface of the top wall 2c (the surface inside the container) to close the opening 2d, and the hole 4b is closed by the bulging portion 2f. Problems such as dripping of liquid do not occur.

  Then, as shown in FIG. 4B, when the spherical body 5 is pressed against the part to be applied, the spherical body 5 presses the projection 4d toward the inside of the container, and the valve body 4c is separated from the top wall 2c, and the opening 2d Is released. For this reason, the content liquid introduced into the internal space N passes through the gap between the spherical body 5 and the curved wall 2e through the hole 4b and between the adjacent protrusions 4d. Thus, if the container body 1 is moved, the rotating spherical body 5 can be applied to the place where the content liquid is to be applied. When the content liquid passes between the protrusions 4d, the flow is restricted by the protrusions 4d, so that the amount of content liquid dispensed can be restricted. Further, since the valve body 4c abuts against the inner annular wall 3f in a state where the spherical body 5 is pressed, the first communication port 3c and the second communication port 3d are closed, and the content liquid traveling from the accommodation space M to the internal space N is closed. Is interrupted. In other words, since only the content liquid stored in the internal space N is poured out, the content liquid is not excessively poured out.

  After the content liquid is spread to the place where the application is desired, the container body 1 is lifted to bring the valve body 4c into contact with the top wall 2c again to close the opening 2d. That is, since the supply of the content liquid toward the gap between the spherical body 5 and the curved wall 2e is stopped, the dripping of the content liquid can be effectively suppressed even before the container body 1 is returned to the upright posture. In addition, after returning the container main body 1 to the upright posture, the content liquid introduced into the internal space N flows out again toward the storage space M, but a part of the content liquid remains inside the inner annular wall 3f. . However, since the opening 2d is closed even in this state, there is no possibility that the liquid in the inner annular wall 3f is deteriorated by the outside air.

  Therefore, according to the dispensing container of this embodiment, it is possible to prevent the content liquid from dripping to an unintended part, and it is possible to prevent excessive dispensing of the content liquid.

  Further, according to the dispensing container of this embodiment, since the opening area of the first communication port 3c is made smaller than the opening area of the second communication port 3d, the container body 1 is accommodated when displaced in the inverted posture. The content liquid in the space M is preferentially introduced into the internal space N from the second communication port 3d having a large opening area, and air accumulated in the internal space N is discharged from the first communication port 3c. Therefore, if the container body 1 is displaced to the inverted posture, the content liquid can be immediately poured out.

  Furthermore, according to the dispensing container of this embodiment, since the first communication port 3c is positioned on the bottom side of the second communication port 3d, the contents when the container body 1 is displaced to the inverted posture. While the liquid moves to the side opposite to the bottom (the first communication port 3c side), air having a specific gravity smaller than that of the content liquid moves to the second communication port 3d side. It will be done more reliably.

  Further, according to the dispensing container of this embodiment, the dispensing cap 2 has the curved wall 2e surrounding the opening 2d, and the protrusion 4d can be pushed into the curved wall 2e by the curved wall 2e and rotated. Since the spherical body 5 that can be supported is provided, the poured out contents can be spread uniformly. In general, a roll-on type pouring container having a spherical body often dispenses a low-viscosity content liquid. However, in the pouring container according to the present invention, the dripping of the content liquid is low even if the viscosity is low. And excessive pouring can be prevented.

  Next, a dispensing container according to another embodiment of the present invention will be described with reference to FIG. Fig.5 (a) is the top view which showed the extraction container of other Embodiment of this invention, FIG.5 (b) is sectional drawing in the side view of the extraction container.

  The dispensing container of this embodiment includes a dispensing cap 6 and a check valve 7 that are partially different from the dispensing cap 2 and the check valve 4 while using the container body 1 and the holder 3 described above. is there.

  The extraction cap 6 is partially different from the previously described claw portion 2a, base portion 2b, top wall 2c, opening 2d, bulge portion 2f, engagement wall 2g, and seal wall 2h, but has the same function. A claw portion 6a, a base portion 6b, a top wall 6c, an opening 6d, a bulging portion 6f, an engagement wall 6g, and a seal wall 6h.

  The check valve 7 includes an outer edge portion 7a, a hole 7b, and a valve body 7c having the same form and function as those of the outer edge portion 4a, the hole 4b, and the valve body 4c described above. Moreover, the projection 7d formed larger than the projection 4d is provided.

  Even in such a dispensing container, since the opening 6d is normally closed by the valve body 7c, the liquid content does not drip even if the container body 1 is displaced to the inverted posture. Further, when the container body 1 is displaced in the inverted posture and pressed against the place where the projection 7d is to be applied, the valve body 7c is separated from the top wall 6c and the opening 6d is opened. The content liquid thus prepared is poured out from the opening 6d through the hole 7b, and can be applied through the protrusion 7d. In addition, since the valve body 7c is in contact with the inner annular wall 3f in the state where the projection 7d is pressed, the first communication port 3c and the second communication port 3d are closed and the housing space M is moved to the internal space N. The flow of content liquid heading is blocked. For this reason, also in this embodiment, since only the content liquid accommodated in the internal space N is poured out, the content liquid is not excessively poured out.

  As mentioned above, although demonstrated based on the example of illustration, the extraction container of this invention is not limited to the thing of the structure of embodiment mentioned above. For example, the dispensing cap may be screwed to the container body. Further, the dispensing cap and the holder may be formed integrally, and the check valve may be configured to be held by the dispensing cap or the holder by a known means. The number of openings and protrusions may be at least one, and the shape thereof can be changed as appropriate.

  Thus, according to the dispensing container of the present invention, the content liquid does not leak out from the opening even if the container body is displaced to the inverted posture, so that the content liquid can be prevented from dripping to an unintended part. Further, since the opening is opened only when the protrusion is pressed, excessive discharge of the content liquid can be prevented.
