Description

[Detailed Description of the Invention] [Industrial field of application] The present invention accommodates seasonings, edible oil, shampoo, conditioner, etc., and discharges the contents by pressing the body with the mouth down Attached to the mouth of the push-out container as described above, when the discharge of the contents is completed, the discharge is stopped automatically by stopping the pressing, and the contents are not discharged even when the container is turned upside down. It is about the department.

[Conventional technology]

In general, an extrudable container for seasonings or the like is provided with a nozzle directly from its mouth or provided with a nozzle at its mouth to discharge the contents.

However, if the contents are discharged as described above and you forget to close the lid after discharging, if you lay it on its side or turn it upside down, the contents will be discharged from the mouth due to its weight and may pollute the surrounding area. .

Therefore, the discharge port of the container is provided with a sheet-shaped or concave nozzle-shaped portion having a slit or cut formed in the central portion,
It has been proposed that the fluid inside the container flows out from the slits or cuts only when the container is pressed. For example, JP-A-61-33927, JP-B-30-14482, JP-B-55-56133, JP-A-60-167759 (JP-A-5-56759)
9-54001) and the drawings and drawings.

However, in the sheet-shaped or concave nozzle-shaped portions in the inventions related to these proposals, the fluid inside the container flows out from the slit or the like due to the pressure of the flowing out, but when the restoring force of the container itself is weak, the pressing of the container is stopped. When this happens, there is a problem that the nozzle-shaped part will be delayed in restoring to its original state and the outflow is not well cut. Conversely, if the restoring force of the container itself is too strong, the negative pressure generated inside the container will become too strong. There is a problem that the nozzle-shaped portion is drawn into the container beyond the original state, the slits and the like are opened, and the fluid flows out.

[Problems to be solved by the device]

Therefore, an object of the present invention is to discharge an extrudable container in which the contents do not flow out even if the container is placed upside down after the lid is removed, and the inside of the mouth is not contaminated even when the lid is always removed. Is to provide the department.

[Means for Solving the Problems]

The present invention has been made for the purpose of solving the above-mentioned problems, and one of the configurations is an extrusion type container made of a synthetic resin or the like, in which a shallow spherical shell shape is appropriately formed in the center part on the mouth part thereof. The holding member having rigidity provided with the contents passage hole is arranged by inserting the spherical shell-shaped portion, and the holding member has a spherical shell-like shape having a radius of curvature equal to or slightly smaller than that in the central portion on the holding member. A nozzle member composed of an elastic body provided with a slit for discharging contents is arranged, and the nozzle member is attached to the mouth portion in close contact with a holding member,
Another structure is an extrudable container made of synthetic resin or the like, in which a nozzle member made of an elastic body having a shallow spherical shell shape and a slit for discharging contents in the central portion is provided on the mouth of the container. The protruding portion is arranged, and on the nozzle member, a restraining member having a rigidity having a spherical shell shape having a curvature radius equal to or slightly larger than that and having a content discharge port in the central portion is arranged, The holding member is closely attached to the nozzle member and attached to the mouth.

Thus, the former device is stable as it is upside down, but the latter device is installed via the leg member which is higher than the discharge port of the holding member when the holding member is attached to the mouth. If it is attached, the leg member can be stably inverted.

[Action]

In the former invention, the push-out container according to the present invention has a structure in which the lid is removed, the container is turned upside down and the body is pressed, the contents are pressed and pushed down the nozzle member, and the slit is opened. Is discharged from the slit, and after discharging, if the pressing of the container body is stopped, the nozzle member is automatically restored by the negative pressure generated in the container, so the contents will flow out even if it is inverted in that state. There is no fear.

Further, in the latter device, as in the former case, if the container is turned upside down and its body is pressed, the slit of the nozzle member is opened and the contents are discharged to the discharge port of the suppressing member. It is discharged and discharged from the discharge port to the outside, and if the pressing is stopped after the discharge, it is automatically restored by the negative pressure generated in the container.

In addition, since the nozzle member is closely attached to the restraining member, even if the negative pressure is too weak or, on the contrary, too large, it quickly restores to its original state and is deformed beyond its original state. You won't be forced to.

Therefore, even if the container is left as it is after opening the lid and the container is turned upside down, there is no possibility that the contents will flow out.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of an essential part of an example of the present invention, FIG. 2 is a plan view of the same, FIG. 3 is a sectional view of an essential part of another example, and FIG. 4 is a plan view of the same.

In FIGS. 1 and 2, 1 is the mouth of the container A, 2 is a shallow spherical shell-shaped 2a, and a square-shaped content passage hole 2b is formed in the center.
The pressing member is provided with the spherical shell-shaped portion 2a fitted in the mouth portion 1 and the peripheral edge portion 2c thereof is arranged on the mouth portion 1. Reference numeral 3 indicates a curvature from the spherical shell-shaped portion 2a of the holding member 2. A nozzle member having a spherical shell shape 3a with a slightly smaller radius, a slit 3b for discharging the contents in the center, and a mounting cylinder 3d in the peripheral edge 3c. 3d is tightly attached to the mouth 1 through the O-ring 4. C is a lid attached to the mouth portion 1, and the extrusion container of an example of the present invention is constituted by the above.

In this push-out type container, the slit 3b of the nozzle member 3 is closed in the state shown in the figure, so that even if the cover C is removed and the container A is inverted in this state, the contents will not flow out.

Thus, in order to discharge the contents from the state shown in the drawing, the lid C is removed, the container A is inverted, and the body is pressed, so that the contents pass through the contents passage hole 2a of the holding member 2 and the nozzle. As a result of pressing the spherical shell-shaped portion 3a provided with the slit 3b of the member 3, the spherical shell-shaped portion 3a of the nozzle member 3 is gradually pushed downward and inverted, and a gap is formed in the slit 3b, so that the contents are external Is discharged to. After the discharge, if the pressing of the body is stopped, a negative pressure is generated in the container, and the nozzle member 3 is automatically sucked inward by the spherical shell-shaped portion 3a protruding outward, and the restraining member 2 And the slit 3b is completely closed. Therefore, even if it is left as it is, there is no possibility that the contents will flow out.

Further, in FIGS. 3 and 4, 11 is the mouth of the container, 12
Is a nozzle member having a shallow spherical shell-shaped 12a and a slit 12b for discharging contents in the central portion, the spherical shell-shaped portion 12a is directed outward, and its peripheral portion 12c is arranged above the mouth 11. I am doing it. 13
Is a spherical shell 13a having a slightly larger radius of curvature than the spherical shell 12a of the nozzle member 12, and the slit 1
Content outlet 13b with an elliptical shape longer than 2b and a circular top
With the holding member provided with, the peripheral edge portion 13c is arranged on the peripheral edge portion 12c of the nozzle member 12, and is fixed to the mouth portion 11 via the support leg 14 from above. The support leg 14 is formed so that the discharge port 13c is positioned higher than the lower part when the container is inverted, and the O-ring 15 tightly attaches the contents so that the contents will not leak. C is a lid attached to the mouth 11.

In the extrudable container according to another example of the present invention configured as described above, the slit 12b of the nozzle member 12 is closed in the illustrated state as in the previous example. Even if it is upside down, the contents will not leak.

Thus, in order to discharge the contents from the state shown in the drawing, the lid C is removed, the container is turned upside down, and the body is pushed, so that the contents push up the spherical shell-shaped portion 12a of the nozzle member 12, 12 slits 12b are opened to hold the pressing member from the slits 12b.
It is discharged to the discharge port 13b of 13 and is discharged to the outside from the discharge port 13b. If the pressing of the body is stopped after discharging, a negative pressure is generated in the container, the nozzle member 12 is sucked inward and automatically restores, and the holding member 13 holds the nozzle member 12 inward. Therefore, the slit 12b is in a completely closed state. Therefore, even if it is left as it is, there is no possibility that the contents will flow out.

The restraining members 2 and 13 are made of a rigid synthetic resin, and the nozzle members 3 and 12 are made of a synthetic resin elastic body.

Further, in the present invention, the contents passage hole 2a of the holding member 2 and the contents discharge port 13b of the holding member 13 may have any suitable shape such as an elliptical shape or a quadrangular shape.

[Effect of device]

The present invention is as described above, in an extrudable container,
By pressing the body of the container and opening the nozzle member to discharge the contents, after stopping the pressing of the body, the negative pressure generated in the container automatically restores and closes the opened nozzle member. Therefore, after using the contents, there is no risk of the contents leaking out even if the container is left in the inverted state, and since the nozzle member is closely attached to the holding member, Even if the negative pressure of is too weak, or conversely too large, it will quickly restore to its original state, and will not be deformed beyond its original state.
Therefore, the problems found in the conventional extrusion type container are almost eliminated.
