JP2019-99211A

In this type of container with a measuring cap, there is room for improvement in allowing the content liquid to be measured with a simple operation.

One of the objects of the present invention is to provide a container with a measuring cap that allows the content liquid to be measured with a simple operation.

One aspect of the container with a measuring cap of the present invention includes a container main body in which a liquid content is stored, a bottomed cylindrical inner plug member provided at the mouth of the container main body, and a bottomed cylindrical inner plug member that covers the inner plug member from above. A cap body having a cylindrical shape, a measuring chamber defined between the inner stopper member and the cap body, and a lid body that releasably closes a spout hole penetrating the top wall of the cap body. , the inner plug member includes an inner cylinder extending upward from the bottom wall of the inner plug member, an outer cylinder fitted onto the inner cylinder so as to be movable up and down, and an inner cylinder of the bottom wall. an air displacement cylinder that extends upward from a position different from that of the cylinder and communicates the inside of the container body with the measuring chamber; the inner cylinder penetrates the peripheral wall of the inner cylinder; The outer cylinder has an inner opening hole that communicates with the inside, and the outer cylinder has an outer opening hole that penetrates the peripheral wall of the outer cylinder, and an engaged part that is arranged to overlap with the spout hole when viewed from the top and bottom. , the lid body has an engaging part that removably engages with the engaged part, and the outer cylinder has the outer opening hole and the inner opening hole communicating with each other, Communication between the measuring chamber and the inside of the container body is cut off by blocking communication between the lowered position where the measuring chamber and the inside of the container main body communicate with each other, and the outer opening hole and the inner opening hole. In the lowered position, the engaged part and the engaged part are engaged, and the lid closes the spout hole, and the lid moves up and down between a raised position and a lowered position. At this position, the engagement between the engaged portion and the engaging portion is released, and the lid opens the spouting hole.

The procedure for measuring and pouring out the liquid content using this container with a measuring cap is, for example, as follows.
First, the outer cylinder is placed in the lowered position, the engaged portion is engaged with the engaging portion, and the container is placed in an inverted position with the lid closing the spouting hole. The liquid content of the container body flows into the metering chamber through the inside of the inner cylinder, the inner opening hole, and the outer opening hole. At this time, the air in the measuring chamber flows out into the container body through the air displacement tube. That is, air and the liquid content are replaced in the measuring chamber.

Next, the inverted container is returned to an upright position. A predetermined amount of the liquid content is measured and stored in the metering chamber depending on the position of the upper end opening of the air displacement cylinder and the like.

Next, open the lid to open the spout hole. At this time, the engaging part of the lid pulls up the engaged part of the outer cylinder, so the outer cylinder rises to the raised position, and by further opening the lid, the engaging part and the engaged part are connected. The engagement is released. Moreover, by moving the outer cylinder to the raised position, communication between the outer opening hole and the inner opening hole is cut off, and communication between the measuring chamber and the inside of the container body is also cut off.

When the container is tilted from this state and the spout hole is directed downward, a predetermined amount of the content liquid stored in the metering chamber is poured out through the spout hole to the outside of the cap.
After pouring out the contents, the lid is closed to block the pouring hole. At this time, the engaging part of the lid presses down the engaged part of the outer cylinder, so the outer cylinder descends to the lowered position, and by further closing the lid, the engaging part and the engaged part are brought together. Re-engaged.

According to the container with a measuring cap of the present invention, there is no need for the conventional operation of removing the measuring cap from the container body, pouring in the liquid content, and measuring it. Specifically, in the present invention, the content liquid can be measured by a simple operation of placing the container in an inverted position and returning it to an upright position. Then, by opening the lid, a predetermined measured amount of the content liquid can be poured out. Therefore, it is easy to operate.

In the container with a measuring cap, the container body can be deformed by squeezing, the direction in which the content liquid is poured out from the spout hole is the front side in the front-rear direction of the container with a measuring cap, and the air displacement cylinder is is preferably arranged in line with the inner cylinder in the left-right direction perpendicular to the front-rear direction when viewed from the top and bottom.

This container with a measuring cap can be used, for example, when you want to pour out an additional amount of the liquid content, by opening the lid and holding the pouring hole facing downward, and squeezing the container body. The content liquid can be poured out through the air displacement tube.

During such use, if the air displacement tube is arranged side by side with the inner tube in the left-right direction as in the above configuration, the liquid content poured out from the air displacement tube will be less likely to hit the inner tube and the outer tube. Become. The content liquid can be poured out stably from the air displacement cylinder.

In the container with a measuring cap, the container main body can be squeeze-deformed, the air displacement tube has a communication hole that communicates the measurement chamber with the inside of the container main body, and the communication hole has a communication hole that communicates with the inside of the container main body. Preferably, the opening is formed in the bottom wall of the plug member.

By squeezing and deforming the container body, when attempting to additionally pour out an arbitrary amount of the liquid content through the air displacement cylinder, as in the above configuration, the communication hole of the air displacement cylinder is connected to the bottom wall of the inner plug member. If it is open, it is easier to pour out the liquid content stably even when the remaining amount of liquid in the container body is low, compared to a configuration in which the air displacement cylinder protrudes downward from the bottom wall, for example. .

According to the container with a measuring cap of the above aspect of the present invention, the content liquid can be measured with a simple operation.

The direction in which the content liquid L is poured out from the pouring hole 35a is the front side in the front-rear direction of the container 10 with a measuring cap (see FIG. 6).
When viewed from the top and bottom, the spout hole 35a and the engaged portion 25b are arranged to overlap. Specifically, when viewed from the top and bottom, the engaged portion 25b is entirely disposed within the spout hole 35a.

The lid body 5 covers the top wall 32 of the cap body 3 from above. The lid body 5 includes a peripheral wall 51, a top wall 52, an opening/closing operation part 55, a closing cylinder 53, and an engaging part 54.

The peripheral wall 51 of the lid body 5 has a cylindrical shape centered on the cap axis O. The outer peripheral portion of the top wall 32 of the cap body 3 is inserted into the lower end opening of the peripheral wall 51 .

The top wall 52 of the lid 5 has a plate shape that extends in a direction perpendicular to the cap axis O. Specifically, the top wall 52 has a disk shape centered on the cap axis O. An outer peripheral portion of the top wall 52 is connected to an upper end portion of the peripheral wall 51.

The opening/closing operation section 55 is arranged at the lower front end of the peripheral wall 51 of the lid body 5. The opening/closing operation part 55 has a protrusion shape that projects forward from the front lower end of the peripheral wall 51.

The closing cylinder 53 extends downward from the top wall 52. The closing cylinder 53 has a cylindrical shape that extends in the vertical direction, and specifically has a cylindrical shape. The closing cylinder 53 is arranged coaxially with the central axis C of the inner cylinder 24 and the outer cylinder 25.

As shown in FIG. 1, in the closed state of the lid 5 (closed state of the lid 5), the closing cylinder 53 fits into the spout hole 35a. Specifically, the lower end of the outer circumferential surface of the closed cylinder 53 is in liquid-tight contact with the lower end opening of the spout hole 35a over the entire circumference in the cylinder circumferential direction. Thereby, the closing cylinder 53 closes the spouting hole 35a.

In addition, as shown in FIG. 5, when the lid 5 is open (open state of the lid 5), the fitting state of the closing cylinder 53 to the spout hole 35a is released, and the spout hole 35a is exposed to the outside of the cap. It will be released. That is, the closing cylinder 53 of the lid body 5 releasably closes the spouting hole 35a.

As shown in FIG. 1, the engaging portion 54 extends downward from the top wall 52. As shown in FIG. In this embodiment, the engaging portion 54 has a cylindrical shape centered on the central axis C, and specifically has a cylindrical shape. The diameter of the engaging portion 54 is smaller than the diameter of the closing cylinder 53. The engaging portion 54 is arranged inside the closing cylinder 53 in the cylinder radial direction. The lower end of the engaging portion 54 protrudes lower than the lower end of the closing tube 53 .

Further, the diameter of the engaging portion 54 is larger than the diameter of the engaged portion 25b of the outer cylinder 25. The engaged portion 25b is fitted into the lower end opening of the engaging portion 54. Thereby, the engaged portion 25b is engaged with the engaging portion 54.

The engaging portion 54 has an engaging protrusion 54a.
The engagement protrusion 54a projects inward in the cylinder radial direction from the inner circumferential surface of the engagement portion 54 and extends in the cylinder circumferential direction. The engagement protrusion 54a is a circular ring-shaped protrusion centered on the central axis C. The engagement protrusion 54a is arranged at the lower end of the inner circumferential surface of the engagement portion 54.

As shown in FIG. 1, in the closed state of the lid body 5, the engaging protrusion 54a is disposed below the engaged protrusion 25e, contacts the engaged protrusion 25e from below, Or face each other with a gap.

When the user operates the opening/closing operation unit 55 and opens the lid 5 from the closed state shown in FIG. 1 to the open state shown in FIG. 5, the engaging protrusion 54a is covered. By pushing up the engagement protrusion 25e, the outer cylinder 25 is pulled upward. The outer cylinder 25 moves upward relative to the inner cylinder 24, and the locking protrusion 25d of the outer cylinder 25 rides over the climbing protrusion 24e of the inner cylinder 24 upward.

Next, the locking protrusion 25d of the outer cylinder 25 contacts the regulating protrusion 24d of the inner cylinder 24 from below. As a result, further upward movement of the outer cylinder 25 is restricted, and the outer cylinder 25 is placed in the raised position. When the user further opens the lid 5 from this state, the engaging protrusion 54a comes into sliding contact with the engaged protrusion 25e and climbs over the engaged protrusion 25e to the upper side. The fitted state with the engaging portion 25b is released. That is, the engagement of the engaging portion 54 with the engaged portion 25b is released.
In this way, the engaging portion 54 of this embodiment removably engages with the engaged portion 25b.

Specifically, in the lowered position of the outer cylinder 25 shown in FIG. 1, the engaged part 25b and the engaging part 54 are engaged, and the closing cylinder 53 of the lid body 5 closes the spouting hole 35a. Further, in the raised position of the outer cylinder 25 shown in FIG. 5, the engagement between the engaged part 25b and the engaging part 54 is released, and the closing cylinder 53 of the lid body 5 opens the pouring hole 35a.

As shown in FIG. 1, the hinge 6 connects at least the rear end of the peripheral wall 31 of the cap body 3 and the rear end of the peripheral wall 51 of the lid body 5. In this embodiment, the cap body 3, the lid body 5, and the hinge 6 are integrally formed from a single member.

The measuring chamber 4 is defined by the peripheral wall 21 and the bottom wall 23 of the inner plug member 2, the fitting cylinder part 34 and the top wall 32 of the cap body 3, and the closing cylinder 53 and top wall 52 of the lid body 5. It is a room (space). As shown in FIG. 1, the container is changed from an upright position with the lid 5 closed to an inverted position as shown in FIG. 4, and then returned to an upright position (see FIG. 5). , a predetermined amount (or an arbitrary amount) of the content liquid L is stored in the measuring chamber 4.

The procedure for measuring and dispensing the content liquid L using the container 10 with a measuring cap of the present embodiment described above is, for example, as follows.
First, as shown in FIG. 1, the outer cylinder 25 is in the lowered position, the engaged portion 25b and the engaging portion 54 are engaged, and the lid body 5 closes the spout hole 35a, as shown in FIG. Place the container in an inverted position as shown. The liquid content L of the container body 1 flows into the measuring chamber 4 through the inside of the inner cylinder 24, the inner opening 24b, and the outer opening 25a. At this time, the air in the measuring chamber 4 flows out into the container body 1 through the air displacement tube 26. That is, air and the content liquid L are replaced in the measuring chamber 4.

Next, the inverted container is returned to the upright position (see FIG. 5). A predetermined amount of the liquid content L is measured and stored in the metering chamber 4 according to the position of the upper end opening of the air displacement cylinder 26 and the like.

Next, as shown in FIG. 5, the lid 5 is opened to open the spout hole 35a. At this time, the engaging part 54 of the lid 5 pulls up the engaged part 25b of the outer cylinder 25, so the outer cylinder 25 rises to the raised position, and by further opening the lid 5, the engaging part 54 The engagement between the engaged portion 25b and the engaged portion 25b is released. Further, by moving the outer cylinder 25 to the raised position, communication between the outer opening hole 25a and the inner opening hole 24b is cut off, and communication between the measuring chamber 4 and the inside of the container body 1 is also cut off.

When the container is tilted from this state and the spout hole 35a is directed downward as shown in FIG. Poured out.
After pouring out the content liquid L, as shown in FIG. 1, the lid 5 is closed to block the pouring hole 35a. At this time, the engaging part 54 of the lid 5 pushes down the engaged part 25b of the outer cylinder 25, so the outer cylinder 25 descends to the lowered position, and by further closing the lid 5, the engaging part 54 and the engaged portion 25b are engaged again.

According to the container 10 with a measuring cap of the present embodiment, there is no need to remove the measuring cap from the container body 1, pour in the liquid content L, and measure it as in the conventional case. Specifically, in this embodiment, the content liquid L can be measured by a simple operation of placing the container in an inverted position and returning it to an upright position. By opening the lid 5, a predetermined measured amount of the content liquid L can be poured out. Therefore, it is easy to operate.

Further, in this embodiment, the body 12 of the container body 1 can be squeeze-deformed, and as shown in FIG. 2, the air displacement cylinder 26 is arranged in line with the inner cylinder 24 in the left-right direction.
This container 10 with a measuring cap is placed in a position where the lid 5 is opened and the pouring hole 35a is directed downward, as shown in FIG. By squeezing and deforming the container body 1, the content liquid L can be poured out through the air displacement cylinder 26.

In such use, if the air displacement tube 26 is arranged side by side with the inner tube 24 in the left-right direction as in the above configuration, the liquid content L poured out from the air displacement tube 26 will be transferred to the inner tube 24. And it becomes difficult to hit the outer cylinder 25. The content liquid L can be poured out stably from the air displacement cylinder 26.

Further, in this embodiment, the communication hole 26a of the air displacement cylinder 26 opens in the bottom wall 23 of the inner plug member 2.
As shown in FIG. 7, when an arbitrary amount of the liquid content L is to be poured out through the air displacement tube 26 by squeezing and deforming the container body 1, the air displacement tube 26 is If the communication hole 26a is opened in the bottom wall 23 of the inner plug member 2, the liquid content L in the container body 1 will be reduced, compared to, for example, a configuration in which the air displacement tube 26 protrudes downward from the bottom wall 23. Even if the remaining amount of liquid L becomes small, it is easy to pour out the content liquid L stably.

Further, in this embodiment, as shown in FIGS. 1 and 5, the central axes C of the outer cylinder 25 and the inner cylinder 24 are located on the front side of the cap axis O.
In this case, when the lid body 5 rotates around the hinge 6, the radius of curvature of the rotation locus of the engaging portion 54 around the hinge 6 increases in the longitudinal cross-sectional view shown in FIGS. 1 and 5. Therefore, it is possible to ensure a large lifting stroke of the outer cylinder 25 by the lid body 5, and it also becomes easy to ensure a large vertical movement stroke of the outer cylinder 25.

Thereby, while ensuring a large opening area (particularly the vertical dimension) of the outer opening 25a and the inner opening 24b, it is possible to stably switch between communicating and blocking the outer opening 25a and the inner opening 24b. becomes possible. Moreover, since the pouring hole 35a is also located in front of the cap axis O, it is easier to pour out the content liquid L.

Further, in the above-described embodiment, an example was given in which a plurality of inner opening holes 24b are provided in the inner cylinder 24 in a line in the cylinder circumferential direction, and a plurality of outer opening holes 25a are provided in a plurality in the outer cylinder 25 in a line in the cylinder circumferential direction. However, it is not limited to this. Only one inner opening hole 24b and one outer opening hole 25a may be provided.

Further, the cap main body 3 is formed of a transparent member, and may have at least one scale portion on the peripheral wall 31 thereof. Note that when a plurality of scale portions are provided on the peripheral wall 31, the plurality of scale portions are arranged at intervals from each other in the vertical direction.
According to the above configuration, as shown in FIG. 4, the container is placed in an inverted position, and when the content liquid L flowing into the measuring chamber 4 reaches a desired scale (not shown), the container is returned to an upright position. , it is possible to perform metering of any quantity.

Further, the vertical position of the bottom wall 23 of the inner plug member 2 may be equal to or higher than the vertical position of the lower end of the mouth portion 11 of the container body 1. As described in the previous embodiment, the gap between the outer circumferential surface of the lower portion of the peripheral wall 21 of the inner plug member 2 and the inner circumferential surface of the mouth portion 11 is small. Therefore, according to the above configuration, when the container is tilted in a position with the spout hole 35a facing downward, even if the remaining amount of the liquid content L in the container body 1 becomes small, the content liquid L can be poured until the end. Easy to pour without waste.

In addition, the components in the embodiments described above can be replaced with known components as appropriate without departing from the spirit of the present invention, and the embodiments and modifications described above may be combined as appropriate.
