A certain amount of contents in the reservoir are discharged to the outside from the discharge port.

JP 2006-151461 A

  However, this conventional fixed-quantity discharge container moves the contents to the weighing body by the first inversion operation of the container body, and then moves the contents to the storage body by operating the container body upright. Therefore, when the container body is operated upright, a part of the contents weighed almost accurately by the weighing body is partially returned to the container body side. For this reason, the content discharged to the outside from the storage body through the discharge port is reduced from the amount measured by the measuring body.

  Accordingly, an object of the present invention is to provide a quantitative discharge cap and a quantitative discharge container that can easily discharge an accurate amount of contents to the outside.

The quantitative discharge cap according to claim 1 is attached to a container main body that accommodates fluid contents, and has a lower end opening that opens toward the inside of the container main body. And when the container body is turned upside down, the contents in the container body flow into the interior through the outflow cylinder and temporarily. A top-like cylindrical storage body that is stored in the storage body, a measuring body that surrounds the outflow cylinder from the outer side in the radial direction and communicates with the inside of the storage body, and has an internal volume smaller than the storage body, and the measurement And a nozzle part that is arranged side by side with the storage body above the body, and discharges the contents in the measuring body to the outside when the container body is turned upside down. Is.
In this invention, when the container main body is turned upside down, the contents in the container main body flow into the storage body through the upper end opening of the outflow cylinder, and the contents are temporarily stored in the storage body. Next, when the container body is operated upright, the contents in the reservoir flow into the measuring body, and at this time, the excess contents are returned to the container body through the upper end opening of the outflow cylinder. As a result, a certain amount of contents are measured and stored in the measuring body. Subsequently, when the container main body is inverted again, a fixed amount of the measured content is discharged from the nozzle portion to the outside.

The metering discharge cap according to a second aspect is the metering discharge cap according to the first aspect, wherein an outer surface of the upper end portion of the outflow tube is provided with an inclined surface that is inclined so that the upper end opening is narrowed. It is characterized by this.
In the invention according to claim 2, in the peripheral region of the outflow tube, the opening area of the upper portion of the measuring body is gradually enlarged toward the upper end portion of the outflow tube by the inclined surface, and the opening area of the upper end opening of the outflow tube Is gradually reduced. For this reason, when the container body is returned from the inverted state to the upright state, the contents easily flow from the storage body to the weighing body side, and after the weighing body is filled with the contents, the surplus contents are discharged from the outflow cylinder. It becomes easy to flow into the upper end opening. Therefore, when the container main body is returned to the upright state, the measuring body can be reliably filled with the contents, and after filling, the surplus contents can be quickly returned into the container main body.

According to a third aspect of the present invention, there is provided the quantitative discharge cap according to the first or second aspect, wherein the inner surface of the top wall portion of the reservoir is formed in a convex curved shape upward. It is a feature.
In the invention according to claim 3, when the container main body is inverted and then returned to the upright state, the contents in the reservoir flow downward along the curved surface of the inner surface of the reservoir on the top wall side. To do. For this reason, the contents in the storage body easily flow into the weighing body side along the inner surface, and do not easily flow directly into the upper end opening of the outflow cylinder existing in the center of the weighing body. Therefore, when the container main body is returned to the upright state, the measuring body can be reliably filled with the contents.

The quantitative discharge cap according to a fourth aspect of the present invention is the quantitative discharge cap according to any one of the first to third aspects, wherein a portion of the upper end opening of the measuring body located on the nozzle part side is provided by a shielding part. It is characterized by being blocked.
In the invention according to claim 4, when the container body in an upright state is gradually tilted so that the nozzle part is downward, the contents in the measuring body flow toward the nozzle part and are externally exposed from the nozzle part. Discharged. At this time, the portion located on the nozzle portion side of the upper end opening of the measuring body is closed by the shielding portion, so that the contents in the measuring body are restricted from being returned to the storage body. Therefore, the amount of contents discharged from the nozzle part becomes more accurate.

  The metering discharge container according to claim 5 is a metering discharge container comprising: a container main body for storing fluid contents; and a metering discharge cap attached to the container main body for discharging fixed contents. The metering discharge cap has a lower end opening toward the inside of the container main body, an outflow cylinder having an upper end opening, and an upper part of the outflow cylinder.When the container main body is turned upside down, The top cylindrical storage body in which the content in the container body flows into the inside through the outflow cylinder and is temporarily stored; the outflow cylinder is surrounded from the outside in the radial direction; and the inside is the storage body A measuring body having an internal volume smaller than the storage body, and arranged in parallel with the storage body above the measuring body, and the contents in the measuring body when the container body is inverted.

It is a figure which shows a longitudinal cross section.
The quantitative discharge container 1 includes a container main body 10 that houses the contents 2 and a quantitative discharge cap 12 that is attached to the mouth 11 of the container main body 10. The container body 10 and the quantitative discharge cap 12 are formed of a resin material.

Here, the fixed discharge cap 12 is provided with an outflow cylinder 19 that protrudes from the opening of the mouth portion 11 of the container body 10 toward the outside of the container body 10. Hereinafter, the outflow tube 19 side along the central axis o direction of the outflow tube 19 is referred to as an upper side, and the bottom side of the container body 10 is referred to as a lower side. Further, a direction orthogonal to the central axis o of the outflow cylinder 19 is referred to as a radial direction. Further, “upright” for the container means a posture in which the opening of the mouth portion 11 faces upward, and “inverted” means a posture in which the opening of the mouth portion 11 faces downward.
The container body 10 has a male screw 13 formed on the outer periphery of the mouth portion 11. The container body 10 contains a fluid content 2 such as a liquid or powder. In the following description, it is assumed that the content 2 is a liquid such as a liquid detergent.

  The fixed-quantity discharge cap 12 includes a cap-shaped cylindrical cap body portion 14 that is slightly larger than the mouth portion 11 of the container body 10, and a nozzle portion 15 projecting from a part of the outer peripheral wall of the cap body portion 14. A discharge port 16 is formed at the tip of the nozzle portion 15. The cap main body 14 has a female screw 17 formed on the inner peripheral surface of the cylindrical wall 14 a on the lower end side, and the female screw 17 is screwed into the male screw 13 of the mouth portion 11 of the container main body 10. Reference numeral 18 in the drawing denotes a seal cylinder that is coaxially disposed inside the cylindrical wall 14 a of the cap main body 14 and is fitted into the mouth 11 of the container main body 10. The seal cylinder 18 is suspended from the lower surface of an annular flange extending radially inward from the inner peripheral wall of the cap main body portion 14, and the outflow cylinder 19 is formed with a smaller diameter than the seal cylinder 18. It stands up from the inner edge of the annular flange.

In the substantially lower half of the inside of the cap main body 14, the lower end opening communicates with the inside of the container main body 10 through the seal cylinder 18 and the upper end opening 19 a opens upward, and the outer peripheral area of the outflow cylinder 19. And an annular measuring body 20 formed in a concave shape downward.
As shown in FIG. 2, when the container main body 10 is turned upside down, the content 2 in the container main body 10 flows through the outflow cylinder 19 into the upper half of the cap main body 14 temporarily. A storage body 21 is provided to be stored. The storage body 21 is provided coaxially with the outflow cylinder 19 on the upper side of the upper end opening 19 a of the outflow cylinder 19. The storage body 21 and the measuring body 20 communicate with each other through a space (communication portion) between the peripheral wall of the measuring body 20 and the outflow cylinder 19. In addition, the inner surface of the storage body 21 on the top wall side (upper side) is formed in a hemispherical curved surface convex upward.

The root portion side of the nozzle portion 15 communicates with the radially outer position of the upper edge portion of the outflow tube 19 in the outer peripheral wall of the cap body portion 14. Therefore, the base portion side region of the nozzle portion 15 constitutes a part of the measuring body 20.
The measuring body 20 configured in this way and the storage body 21 disposed on the upper side thereof have different internal volumes, and the internal volume of the upper storage body 21 is relative to the internal volume of the lower measuring body 20. It is set large enough.
The contents 2 stored in the measuring body 20 are filled with the surplus contents 2 through the upper end opening 19 a of the outflow cylinder 19 after the contents 2 flowing from the storing body 21 into the measuring body 20 fill the measuring body 20. By returning to the above, a constant amount is always maintained.

The nozzle portion 15 is arranged above the measuring body 20 in the radial direction with the storage body 21. For this reason, when the container body 10 is tilted in the inverted direction so that the nozzle portion 15 side is downward as shown in FIG. The content 2 passes through the nozzle portion 15 and is discharged from the discharge port 16 to the outside.
Incidentally, a separate shielding member 22 (shielding portion) made of resin is attached to a part of a space (communication portion) between the peripheral wall of the weighing body 20 and the outflow cylinder 19.
FIG. 5 is a diagram showing a single item of the shielding member 22.
As shown in FIG. 5, the shielding member 22 is formed in an arc shape having a radial width in a plan view, and is measured in the region on the side close to the nozzle portion 15 around the outflow cylinder 19. It arrange | positions so that the communication between the body 20 and the storage body 21 may be interrupted | blocked. Therefore, as shown in FIG. 4, when the container body 10 is tilted in the inverted direction, the contents 2 in the weighing body 20 may flow into the storage body 21 through the vicinity of the root portion of the nozzle portion 15. It is regulated by the shielding member 22.
Here, the shielding member 22 in this embodiment is provided more than half the circumference of the communication portion. Specifically, the arc-shaped portion of the shielding member 22 is formed in a substantially U shape that sandwiches the outflow tube 19 in the radial direction, and this arc-shaped portion extends from the nozzle portion 15 side in the radial direction. It extends so as to exceed.
In addition, the storage body 21 and the measurement body 20 are connected in the remaining area | region 30 without the shielding member 22 among the above-mentioned separation spaces. Further, a guide groove 22 a is formed on the upper surface side of the shielding member 22 so as to surround the peripheral area of the upper end opening 19 a of the outflow cylinder 19 in an arc shape. The guide groove 22a guides the content 2 on the shielding member 22 to the remaining area 30 when the container body 10 changes from the inverted state to the upright state.

  In addition, an inclined surface 23 is formed on the outer surface of the upper end portion of the outflow cylinder 19 so as to be inclined so that the upper end is narrowed. The inclined surface 23 is provided in a portion of the outer peripheral surface of the outflow cylinder 19 that separates the remaining region 30. In addition, the inclined surface 23 is preferably provided over at least the entire circumferential region of the remaining region 30. The inclined surface 23 gradually increases the opening area of the remaining region 30 of the weighing body 20 toward the upper end portion of the outflow cylinder 19, and the opening area of the upper end opening 19 a of the outflow cylinder 19 is increased to the upper end portion. It is gradually reduced toward.

In addition, the constant rate discharge cap 12 of this embodiment is injection-molded with the cap main body portion 14 and the upper half portion and the lower half portion of the nozzle portion 15 in a halved state with the vicinity of the upper portion of the outflow cylinder 19 as a boundary. The upper half and the lower half are connected to each other by a hinge part 24. After the injection molding, the shielding member 22 is sandwiched between the upper half and the lower half, and in that state, the hinge part 24 is bent 180 °. The upper half and the lower half are integrated by concave and convex fitting. In the figure, L is a boundary line between the upper half and the lower half.
In this embodiment, the cap main body portion 14 and the nozzle portion 15 are divided into an upper half portion and a lower half portion with the immediate vicinity of the upper portion of the outflow cylinder 19 as a boundary, and can be injection molded simultaneously with one mold. Since the manufacturing efficiency is improved and the mold is cut near the upper portion of the outflow cylinder 19, the shielding member 22 can be easily assembled in the space between the peripheral wall of the measuring body 20 and the outflow cylinder 19.

Next, the actual movement of the contents 2 when the contents 2 are discharged from the fixed discharge container 1 by a certain amount will be described.
First, when the fixed-quantity discharge container 1 is operated from the upright state to the inverted state, the content 2 in the container body 10 flows into the storage body 21 through the upper end opening 19a of the outflow cylinder 19 as shown in FIG. Then, a predetermined amount of the content 2 is temporarily stored in the storage body 21.
Next, when the quantitative discharge container 1 is operated to return to the upright state from this state, the content 2 in the storage body 21 passes through the space outside the outflow cylinder 19 as shown in FIG. Flows in. At this time, since the space between the peripheral wall of the weighing body 20 and the outflow cylinder 19 is partially blocked by the shielding member 22, the content 2 in the storage body 21 flows into the weighing body 20 through the remaining region 30. .
Further, at this time, a part of the contents 2 is directly returned into the container body 10 through the upper end opening 19a of the center outflow cylinder 19. However, when the posture of the quantitative discharge container 1 is changed from the inverted state to the upright state, the contents 2 are stored. Since the content 2 in the body 21 tends to flow downward along the hemispherical curved surface of the top wall portion of the storage body 21, the return amount to the container body 10 can be reduced. Further, the content 2 on the shielding member 22 flows in the direction of the measuring body 20 along the guide groove 22a.

  Here, since the internal volume of the storage body 21 is set sufficiently larger than the internal volume of the measuring body 20, when the inside of the measuring body 20 is filled with the contents 2 as described above (see FIG. 1), Thereafter, the remaining contents 2 overflow from the upper end opening 19 a of the outflow cylinder 19 and are all returned to the container body 10. As a result, a predetermined amount of the content 2 is accurately measured and stored in the measuring body 20.

Subsequently, when the metering discharge container 1 is operated so as to be gradually inverted from this state as shown in FIG. 4 with the nozzle portion 15 being lowered, the contents 2 in the measuring body 20 are moved to the nozzle portion. It is discharged to the outside through 15 discharge ports 16. At this time, an accurate amount of the content 2 measured by the measuring body 20 is discharged from the discharge port 16.
Further, when the metering discharge container 1 is operated in an inverted state in this way, the contents 2 in the container body 10 begin to flow into the storage body 21 as shown in FIG. 4, and are prepared for the next metering discharge.

  As described above, in the fixed discharge container 1 (fixed discharge cap 12), when the fixed discharge container 1 is returned from the inverted state to the upright state, the contents 2 in the reservoir 21 are placed in the measuring body 20. Since the content 2 that flows in and exceeds the internal volume of the measuring body 20 is returned to the container body 10 through the upper end opening 19a of the outflow cylinder 19, an accurate amount of the content 2 is always supplied from the discharge port 16. Can be discharged outside.

  Moreover, in this fixed quantity discharge container 1 (fixed quantity discharge cap 12), since the inclined surface 23 which inclines so that an upper end may be narrowed is provided in the outer surface of the upper end part of the outflow cylinder 19, the fixed quantity discharge container 1 is in an inverted state. When the contents 2 are easily returned from the storage body 21 to the measuring body 20, the surplus contents 2 flow out after the measuring body 20 is filled with the contents 2. It becomes easy to flow into the upper end opening 19 a of the cylinder 19. For this reason, in the case of this embodiment, when the fixed-quantity discharge container 1 is returned to the upright state, the contents 2 can be reliably filled in the measuring body 20, and the surplus contents 2 are filled after filling. The container body 10 can be quickly returned.

  Furthermore, in the fixed discharge container 1 (fixed discharge cap 12) of this embodiment, since the inner surface of the top wall portion of the reservoir 21 is formed in a convex hemispherical curved surface shape, the fixed discharge container 1 is When returning from the inverted state to the upright state, the content 2 in the storage body 21 flows down along the inner wall of the storage body 21, and the content 2 directly flows into the upper end opening 19 a of the outflow cylinder 19. Can be suppressed. Therefore, the contents 2 can be more reliably filled in the measuring body 20.

  Further, in the fixed discharge container 1 (fixed discharge cap 12), a closing member 22 is provided for closing a region on the side close to the discharge port 16 between the outer periphery of the upper end portion of the outflow cylinder 19 and the peripheral wall of the measuring body 20. Therefore, when the content 2 is discharged from the discharge port 16, the flow of the content 2 from the measuring body 20 to the storage body 21 can be restricted. Therefore, the amount of the contents 2 discharged from the discharge port 16 can be made more constant.

In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary.
For example, in the above-described embodiment, the shielding member 22 is formed in an arc shape having a constant width so as to surround the outside of the outflow cylinder 19, but the range in which the shielding member 22 is arranged can be set as appropriate. Alternatively, it may be formed integrally with the fixed discharge cap 12.
