Japanese Utility Model Publication No. 04-13557

  However, in the above-described conventional discharge container, the contents are discharged from the spout simply by tilting the discharge container. Therefore, it is difficult to discharge the contents in the measurement space little by little, and it has excellent operability. There was room for improvement.

  Therefore, the present invention has been made in view of the above-described circumstances, and the object thereof is to discharge the contents stored in the measurement space little by little, and to have excellent operability. It is to provide a discharge container that can be used.

In order to solve the above problems, the present invention proposes the following means.
The discharge container according to the present invention is an elastically deformable container main body in which contents are accommodated, an inner plug that is attached to the mouth of the container main body and has a communication hole that can communicate with the container main body, A suction cylinder member that extends downward from the bottom side of the container body to the inner plug, communicates inside the communication hole, and has a lower end opening immersed in the contents, and the inner plug includes the inner plug. A measuring cylinder member which covers from above the inner plug and defines a measuring space with the inner plug, and the contents in the measuring space by closing the upper end opening of the measuring cylinder member and elastically deforming it. A discharge membrane member in which an opening through which the discharge membrane member can pass is formed, and the measuring tube member is disposed below the diameter-reduced tube portion , the diameter-reduced tube portion where the discharge film member is disposed , a flare tube portion surrounding the communication hole from the outer side in the radial direction, the upper end of the lower portion and the enlarged diameter cylindrical portion of the reduced diameter cylindrical portion Is formed on the ring plate portion and the multi-stage cylindrical shape with a connecting bets, the lower end of the reduced diameter cylindrical portion is positioned above said communicating hole, the lower end of the reduced diameter cylindrical portion, in the radial direction An inner flange portion projecting inward is formed, and the measuring tube member is made of a transparent or translucent material, and the inside is visible.

With such a feature, first, the container body is elastically deformed, whereby the internal pressure of the container body becomes a positive pressure, and the contents in the container body are sucked up through the sucking cylinder member by this positive pressure. The content sucked up through the sucking cylinder member flows into the measuring space through the communication hole of the inner plug. In this case, an amount of contents corresponding to the deformation amount of the container body flows into the measurement space. Therefore, a desired amount of contents can be measured in the measurement space. In other words, the contents excessively flowing into the measuring space are returned to the container body through the communication hole by stopping or releasing the elastic deformation of the container body. This makes it possible to always measure a certain capacity.
After the measurement, the discharge film member is pressed against a supply location such as the scalp to be elastically deformed, thereby forming an opening in the discharge film member through which the contents in the measurement tube member can pass. A thing will be discharged to a to-be-supplied location.
At this time, it is possible to adjust the size of the opening to be formed, that is, the supply amount of the contents, by adjusting the force with which the ejection film member is pressed against the supply location. Therefore, an amount of contents corresponding to the size of the opening can be discharged little by little from the measurement space, and excellent operability can be provided.

  In addition, the discharge film member may be formed in a curved shape that is recessed downward, and a protrusion that protrudes upward may be formed on a part of the outer peripheral portion of the discharge film member. .

  In this case, the discharge film member is formed in a curved shape that is recessed downward, and a protrusion projecting upward is formed on a part of the outer periphery of the discharge film member. When the film member is pressed against the supply location, the discharge film member is deformed in a distorted manner starting from the protrusion. Thereby, it becomes easy to form the opening of the ejection film member, and the operability can be further improved.

  According to the discharge container according to the present invention, the contents stored in the measurement space can be discharged little by little, and excellent operability can be provided.

The upper stage portion 44 is reduced in diameter as the upper portion is directed upward, and is formed thinner as it is directed upward.

The top portion 41 closes the upper end opening of the measuring cylinder member 8 and is formed in a concave curved shape that protrudes downward. The top 41 is configured to be elastically deformable, and a slit 45 serving as an opening for communicating the inside of the measuring space K with the outside is formed at the center of the top 41 when the top 41 is elastically deformed. . In the illustrated example, the slit 45 has an X-shape (cross shape).
Further, an upper surface protrusion (projection) 46 that protrudes upward is formed on a part of the outer surface of the top 41 in the circumferential direction.

The cover member 51 includes a cylindrical mounting cylinder 52 extending in the container axis O direction, and is undercut fitted to the upper portion of the small-diameter portion 33 described above.

  A stopper ring portion 55 that protrudes inward in the radial direction is formed on the upper end edge of the mounting cylinder 52. The retaining ring portion 55 is located on the small diameter portion 33 of the measuring cylinder member 8 and the lower step portion 43 of the discharge film member 9, and the lower step portion 43 of the discharge film member 9 is connected to the inner flange portion 36 of the measurement tube member 8.

A surrounding wall 56 is formed. The surrounding wall portion 56 has a shorter length along the container axis O direction than the upper step portion 44 of the ejection film member 9.

  As shown in FIG. 1, the overcap 10 is disposed so as to cover the shoulder portion 11 of the container body 2, the discharge film member 9, and the measuring cylinder member 8 from above, and can be attached to and detached from the mouth portion 3 of the container body 2. It is attached to. Specifically, the overcap 10 includes a top cylindrical cap body 61 that covers the discharge film member 9 and the measuring cylinder member 8, and a screwing that extends downward from the lower end edge of the cap body 61 via the cap shoulder 62. A cylinder 63 and an exterior body 64 surrounding the screwed cylinder 63 are provided.

The screwed cylinder 63 has a female threaded portion 65 formed on the inner peripheral surface thereof, and is screwed to the male threaded portion 13 of the mouth 3. The overcap 10 may be detachably attached to the container body 2 by undercut fitting.

The contact portion 68 is formed in a dome shape or a hemispherical shape that protrudes downward, and is in contact with a region of the top portion 41 of the ejection film member 9 where the slit 45 is formed.

  When the overcap 10 is attached to the mouth portion 3, the contact portion 68 contacts the region where the slit 45 is formed in the top portion 41, and the slit 45 is deformed toward the inside of the container body 2, In this case, since the slit 45 is prevented from sticking when the discharge container 1 is on standby, a state where the slit 45 can be easily expanded during use is maintained for a long time. Is possible. It should be noted that the inner surfaces of the slits 45 may be in close contact with each other in a state where the contact portion 68 is in contact with the region of the top portion 41 where the slit 45 is formed.

  In addition, a cap-side inner cylinder portion 69 that protrudes downward is formed in a portion of the top wall portion 67 that is located radially outside the contact portion 68. The cap-side inner cylinder portion 69 is inserted between the outer peripheral surface of the upper step portion 44 of the ejection film member 9 and the inner peripheral surface of the retaining ring portion 55.

Next, the effect | action of the discharge container 1 mentioned above is demonstrated.
First, as shown in FIG. 3, the screwing between the mouth 3 of the container body 2 and the overcap 10 is released, and the overcap 10 is removed. Thereafter, the body 12 of the container body 2 is pressed toward the inside in the radial direction, and the container body 2 is squeezed (elastically deformed) (see the arrow in FIG. 3). As a result, the volume of the container body 2 is reduced.

  And the internal pressure of the container main body 2 becomes a positive pressure with this volume reduction deformation, and the contents in the container main body 2 are sucked upward through the sucking cylinder member 7 by this positive pressure. The contents L sucked up through the sucking cylinder member 7 flows into the measuring space K through the communication hole 4 of the inner plug 5. In this case, an amount of the content L corresponding to the deformation amount of the container body 2 flows into the measurement space K. Then, a desired amount of contents can be measured in the measurement space K by checking the level of the liquid level of the contents L flowing into the measurement space K from the outside of the discharge container 1 through the measurement cylinder member 8. .

When the pressure in the measuring space K rises due to the squeeze deformation of the container body 2, the top portion 41 of the discharge film member 9 is elastically deformed by this pressure rise, so that the slit 45 is expanded and the space between the slits 45 is increased. An opening is formed. Thereby, since the measurement space K communicates with the outside and the pressure in the measurement space K can be released, the container body 2 can be smoothly squeezed and deformed.
Thereafter, when a desired amount of the contents L is stored in the measurement space K, the container body 2 is released from being pressed, and the container body 2 is restored. At this time, if the content L flows into the measuring space K above the lower end opening edge of the communication hole 4 (upper end opening edge of the suction cylinder member 7), the position is positioned above the lower end opening edge of the communication hole 4. The excessive contents to be returned are returned into the container body 2 through the communication hole 4 by stopping or releasing the elastic deformation of the container body 2. Therefore, in the container axis O direction, it becomes possible to always measure a certain amount so that the liquid level of the content in the measuring space K becomes the same height as the lower end opening edge of the communication hole 4. .

  Then, as shown in FIG. 4, after the measurement, for example, the discharge container 1 is tilted or turned upside down so that the discharge posture is such that the container body 2 is on the upper side and the discharge film member 9 is on the lower side. Then, the content L stored in the measurement space K moves to the top 41 side of the ejection film member 9 by its own weight. However, in this state, since the inner surfaces of the slits 45 are in close contact with each other and the measurement space K is closed by the discharge film member 9, the content L stored in the measurement space K is prevented from flowing out to the outside. ing.

Here, the top part 41 of the ejection film member 9 is pressed and elastically deformed, for example, against the supply site T such as the scalp (see the arrow in FIG. 4), the slits 45 are separated from each other, and the measuring cylinder member 8 ( An opening through which the content L in the measuring space K) can pass is formed, and the content L is discharged to the supply location T through this opening.
At this time, it is possible to adjust the size of the opening to be formed, that is, the supply amount of the contents L, by adjusting the force with which the ejection film member 9 is pressed against the supply location T, and excellent operability. Can be provided. When the discharge film member 9 is separated from the supply location T, the top 41 is restored and deformed, so that the inner surfaces of the slits 45 are brought into close contact with each other and the discharge film member 9 is closed. Thereby, the discharge of the content L is stopped.
The supply amount can be adjusted by adjusting the elastic deformation amount of the discharge film member 9. For example, the elastic deformation amount is regulated by adjusting the protruding height of the surrounding wall portion 56, and the measured content is adjusted. It becomes possible to divide and discharge objects by a certain amount.

As described above, according to this embodiment, the container body 2 that can be elastically deformed is provided, and the measuring space K that communicates through the communication hole 4 in the container body 2 is defined between the inner stopper 5 and the measuring cylinder member 8. Therefore, a desired amount of contents can be stored in the measurement space K through the communication hole 4 by squeezing the container body 2.
Then, after the measurement, the discharge film member 9 is elastically deformed to form an opening through which the contents in the measurement space K can pass, and the contents are discharged to the supply location T through this opening. Thereby, since the content of the amount according to the size of the opening can be discharged from the measuring space K little by little, excellent operability can be provided.

  Moreover, since the upper surface protrusion 46 is formed on the top 41 of the discharge film member 9 in the discharge container 1 of the present embodiment, when the top 41 is pressed against the supply location T, the upper surface protrusion 46 starts. Therefore, the top 41 is distorted. Thereby, it becomes easy to form the opening between the slits 45 of the top portion 41, and the operability can be further improved.

  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.

  For example, in the above-described embodiment, the case where the slit 45 is formed in the X shape has been described. However, the present invention is not limited to this, and the Y shape or the I shape may be used, and the small hole 47 as illustrated in FIG. Good. Also in this case, the contents in the measuring space K can pass through the opening due to the elastic deformation of the discharge film member 9 to enlarge the small hole 47 or the vibration generated by the elastic deformation. The object is discharged to the supply location T.

Further, in the above-described embodiment, the configuration in which the upper surface protrusion 46 is formed at one place in the circumferential direction has been described, but a plurality of the upper face projections 46 may be formed in the circumferential direction.
Further, the container body 2 is not limited to a bottomed cylindrical shape, and may be a tube shape or the like.
Furthermore, although embodiment mentioned above demonstrated the case where the top part 41 was formed in the protruding curved surface shape toward the downward direction, it is not restricted to this. For example, it may be formed in a curved shape protruding upward or in a shape other than a curved shape.
In the above-described embodiment, the configuration in which the measuring cylinder member 8 is mounted on the container body 2 has been described. However, for example, a configuration in which the measuring tube member 8 is mounted on the inner plug 5 may be used.

  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.
