Description

TECHNICAL FIELD The present invention relates to a weighing and pouring container capable of weighing and pouring contents contained in a container body.

For example, as shown in Patent Literature 1, a measuring injector having a wide-mouthed measuring cup attached to the mouth of a container body and an introduction hole provided in the upper part of a cover tube standing upright inside the measuring cup. Discharge vessels are known. In this weighing and pouring container, by pressing the body of the container body, the contained contents are allowed to flow out sufficiently into the measuring cup through the introduction hole. A predetermined amount of content remains in the measuring cup by drawing back the content that has flowed out over the height of the hole into the container body. By tilting the container body, the measured contents can be poured out from the measuring cup.

By the way, the weighing pouring container of Patent Document 1 allows the contents to be poured out at once in a manner similar to spilling the contents from an inclined cup. It is conceivable to provide the top opening of the measuring cup with a lid wall having a small-diameter opening for pouring out the contents. In this configuration, when the body of the container is tilted and the body is pressed, the air in the body of the container is introduced into the measuring cup through the introduction hole of the covering tube that stands upright inside the measuring cup. Since the inside can be pressurized, it is thought that the contents can be poured out from the small-diameter opening.

JP-A-2002-68234

By the way, according to the weighing and pouring container configured in this way, it is possible to pour out the weighed contents all at once or pour out in small portions depending on how much pressure is applied to the barrel. However, as in the case of pouring out the contents in small portions, the pouring of the contents is stopped while the contents remain in the measuring cup, and the introduction hole is immersed in the contents. Then, when the body is restored, the contents of the measuring cup may flow back through the introduction hole and return into the container main body, changing the measured amount of the contents.

In addition, if the height of the measuring cup is increased, the volume of the head space can be increased relative to the volume of the measuring space where the contents in the measuring chamber are measured. can be positioned where it is not immersed in the contents in the weighing chamber, preventing backflow of the weighed contents. However, since the total height of the container is increased, the appearance of the container is impaired, and the container tends to fall over when placed on a desk or the like.

An object of the present invention is to solve such problems, and the amount of the measured content changes whether the content is poured out at once or in small portions. To provide a weighing and pouring container which can be made compact by suppressing the height without being put away.

The present invention comprises a container body having a mouth part with an open top and a trunk part connected to the mouth part and having flexibility, and containing contents;
a tubular pipe having one opening positioned near the bottom of the container body;
an intermediate member that has a holding part that holds the pipe, and a tubular part that communicates with the other opening of the held pipe and has an introduction port at its tip, and is held at the mouth;
A weighing chamber surrounding the tubular portion and held by the intermediate member is partitioned and formed to accommodate a predetermined amount of the content introduced from the introduction port between the intermediate member and the intermediate member, and the content of the weighing chamber is exposed to the outside world. a pouring member having a pouring port for pouring out toward
By pressing the body portion while the container body is erected, the contents of the container body introduced from the introduction port through one opening of the pipe through the other opening of the pipe are expelled. It is housed in the weighing chamber, and furthermore, by pressing the barrel while tilting the container body, the liquid is introduced from one opening of the pipe through the other opening of the pipe and from the introduction port. A weighing and pouring container in which the air in the container body pressurizes the weighing chamber to pour out the contents contained in the weighing chamber from the spout,
The pouring member includes an upper outer peripheral wall that surrounds the tubular portion above the mouth, and an inclined ceiling wall that is connected to the upper outer peripheral wall and closes the top surface side of the weighing chamber,
The inclined ceiling wall is inclined with respect to the central axis of the container body with the side on which the outlet is provided downward and the side on which the introduction port is provided upward,
The spout is provided in the inclined ceiling wall and opens in a direction inclined at an angle different from that of the inclined ceiling wall with respect to the central axis of the container body,
The tubular portion has a bent portion that extends upward and then extends on a side opposite to the side where the spout opens with respect to the central axis,
The inclined ceiling wall and the upper outer peripheral wall are a weighing and pouring container connected below the bent portion on the side where the pouring port opens with respect to the central axis.

It is preferable that one opening of the pipe opens on the side opposite to the side on which the spout opens with respect to the central axis.

It is preferable that the intermediate member has a concave portion that protrudes toward the inside of the container body to increase the volume of the measuring chamber.

The tubular portion of the weighing and pouring container of the present invention has a bent portion that extends upward and then extends on the side opposite to the side where the spout opens with respect to the central axis of the container body. . Therefore, when the container body is displaced so that the spout faces downward, the introduction port located at the tip of the tubular portion is positioned higher, so that it is less likely to be immersed in the contents in the weighing chamber. Therefore, it is possible to effectively prevent the contents of the weighing chamber from returning to the container body and changing the amount of the weighed contents even if the body part is restored when the contents are poured out in small portions. . In addition, since the introduction port is less likely to be immersed in the contents without changing the height of the pouring member, the container can be made compact.

If one opening of the pipe is opened on the opposite side of the central axis of the container body to the side on which the spout opens, when the container body is displaced so that the spout faces downward, this The opening will be positioned higher. That is, when the container body is tilted, the opening is effectively prevented from being immersed in the contents of the container body, so that the air in the container body can be reliably supplied to the weighing chamber.

When the intermediate member is provided with a concave portion projecting toward the inside of the container body, the volume of the weighing chamber can be increased without changing the height of the pouring member, so that the container can be made compact. Also, it is possible to more reliably prevent the introduction port from being immersed in the contents when the container body is tilted.

Fig. 3(a) is a partial cross-sectional side view showing the weighing and pouring container in an upright state, and (b) is a side view showing the container in an upright position, with the contents being stored in the container according to still another embodiment of the present invention. It is a figure explaining the situation to pour out. It is a figure explaining the modification of the measurement extraction container shown in FIG. 1 is a weighing and pouring container of a comparative example shown for comparison with the present invention.

An embodiment of a weighing and pouring container according to the present invention will be described below with reference to the drawings. In this specification and the like, the relationship between "top" and "bottom" refers to the direction in which the container body (reference numeral 1) is erected as shown in FIG. 1, unless otherwise specified. For convenience of explanation, the side where the spout (symbol 6c) is located with respect to the central axis (symbol O) of the container body is defined as "front", and the side where the inlet (symbol 5c) is located is defined as "rear".

The weighing pouring container shown in FIG. The intermediate member 3 is composed of a body portion 4 and a tubular portion 5 .

The container body 1 includes a bottom portion 1a having a substantially disc shape, a cylindrical body portion 1b having a substantially cylindrical shape and connected to the outer edge of the bottom portion 1a, and a cylindrical mouth portion having a diameter smaller than that of the body portion 1b. 1c and a male threaded portion 1d provided on the outer peripheral surface of the mouth portion 1c. The container body 1 of this embodiment is made of synthetic resin, and the trunk portion 1b has flexibility. In addition, the container body 1 can accommodate various types of contents such as cleaning agents (for example, liquid laundry detergent) and seasonings. There is no particular limitation on the viscosity of the content to be stored, and it may be relatively low, such as soy sauce, or relatively high, such as sauce or liquid miso. In order to keep the total amount constant even when the contents are poured out in small portions, the air contained in the container main body 1 is also used as described later. For this reason, when the contents are stored in the container body 1, if the container body 1 is completely filled with the contents and no head space is generated, the quantitativeness cannot be guaranteed at the time of the first pouring ( Once the pouring is performed, the content of the container body 1 is reduced and a head space is generated, so the quantitativeness is ensured). Therefore, when the contents are stored in the container main body 1, it is preferable that the contents are not completely filled as shown in the figure.

The pipe 2 has a tubular shape and is curved when viewed from the side, and one opening (bottom side opening) 2a is located near the outer edge of the bottom 1a. The other opening (orifice-side opening) 2b is positioned on the center axis O of the container body 1 inside the mouth 1c.

The body portion 4 has a cylindrical shape and includes a cylindrical holding portion 4a that extends along the central axis O to fit and hold the pipe 2. As shown in FIG. A lower flange 4b extending radially outward is provided at the lower end of the holding portion 4a, and a peripheral wall 4c rising upward is provided at the outer edge of the lower flange 4b. An upper flange 4d extending radially outward is provided at the upper end of the peripheral wall 4c, and a cylindrical lower outer peripheral wall 4e extending downward is provided at the outer edge of the upper flange 4d. there is The upper flange 4d is provided with an annular wall 4f extending downward radially inward of the lower outer peripheral wall 4e, and the inner peripheral surface of the annular wall 4f is provided with a female screw portion 4g. . The body portion 4 can be attached to the container body 1 by screwing the female thread portion 4g into the male thread portion 1d. It should be noted that means using an undercut may be used instead of the mounting means using the male threaded portion 1d and the female threaded portion 4g. Here, in a state in which the main body 4 is attached to the container main body 1, the holding portion 4a, the lower flange 4b, and the peripheral wall 4c (hereinafter collectively referred to as a concave portion) are arranged as shown in FIG. , projecting toward the inside of the mouth portion 1c. Further, when the body portion 4 is attached to the container body 1, a doughnut-shaped packing P is interposed between the mouth portion 1c and the upper flange 4d.

A tubular portion 5 is mounted above the holding portion 4a. The tubular portion 5 includes a cylindrical connecting portion 5a connected to the holding portion 4a, a bent portion 5b extending upward from the connecting portion 5a and then extending rearward in the horizontal direction, and a distal end of the bent portion 5b. and an introduction port 5c that opens sideways.

The pouring member 6 includes an upper outer peripheral wall 6a connected to the lower outer peripheral wall 4e, and an inclined ceiling wall 6b connected to the upper end of the upper outer peripheral wall 6a and inclined upward from the front to the rear. , is held by the body portion 4 so as to surround the tubular portion 5 . Here, a space surrounded by the body portion 4 and the pouring member 6 is called a weighing chamber K. As shown in FIG. Further, the inclined top wall 6b is provided with a spout 6c that communicates with the measuring chamber K and opens so as to be inclined forward.

The lid 7 has a plate-like shape and includes a lid wall 7a that covers the spout 6c and a plug 7b that is provided on the back surface of the lid wall 7a and inserted into the spout 6c. there is A hinge 7c integrally connected with the pouring member 6 is provided behind the lid wall portion 7a.

In order to pour out the contents from the weighing and pouring container having such a configuration, first, as shown in FIG. As a result, the contents housed in the container body 1 are pressurized, and the contents enter the pipe 2 from the bottom side opening 2a, pass through the mouth side opening 2b, and pass through the interior of the tubular part 5, It is introduced into the weighing chamber K through the introduction port 5c. Here, it is assumed that the body portion 1b is sufficiently pressed and the content is accommodated in the weighing chamber K until it exceeds the introduction port 5c. In addition, when introducing the contents into the measuring chamber K, in order to release the air in the measuring chamber K to the outside so that the contents and the air can be smoothly replaced, the lid Body 7 is preferably left open.

After the content is stored in the weighing chamber K, the pressure on the trunk portion 1b is released to restore the trunk portion 1b. When the trunk portion 1b is restored, the internal volume of the container body 1 increases compared to when it was pressed, and the container body 1 is decompressed. will be pulled back to That is, since only the content accumulated below the introduction port 5c remains in the weighing chamber K, a fixed amount of content can be weighed.

After that, as shown in FIG. 2, the container body 1 is tilted so that the spout 6c is oriented downward. At this time, since the air in the container body 1 moves toward the bottom 1a, the bottom-side opening 2a of the pipe 2 is positioned above the liquid surface N1 of the contents. Here, in this embodiment, as shown in FIG. 2, even when the contents stored in the weighing chamber K accumulate on the pouring port 6c side, the introduction port 5c is positioned above the liquid surface N2 of the contents. The volume of the weighing chamber K is set. That is, when the body portion 1b is pressed in this state, the air in the container body 1 is pressurized and enters the pipe 2 from the bottom side opening 2a, and then passes through the tubular portion 5 through the mouth side opening 2b. Then, it is introduced into the weighing chamber K from the introduction port 5c. As a result, the weighing chamber K is pressurized by the introduced air, so that the contents contained in the weighing chamber K can be poured out from the spout 6c. In addition, since the introduction port 5c is located above the liquid surface N2 of the content, the body portion 1b can be filled with the content remaining in the weighing chamber K, as in the case of pouring out the content in small portions. Even if is restored, the contents of the weighing chamber K will not flow back from the introduction port 5c.

In order to position the introduction port 5c above the liquid surface N2 of the contents in the state shown in FIG. Here, the weighing and pouring container of FIG. 7 is shown for comparison with the weighing and pouring container of this embodiment shown in FIGS. , a container body 10, a pipe 20, and a body portion 40 configured in the same manner as the body portion 4. As shown in FIG. On the other hand, the tubular portion 50 is not provided with the bent portion 5b of the tubular portion 5 of the above-described embodiment, and the pouring member 60 is higher than the pouring member 6 .

In the weighing and pouring container shown in FIG. 7, the height of the pouring member 60 is increased to increase the volume of the head space K2 with respect to the volume of the weighing space K1 where the content in the weighing chamber K is weighed. . By increasing the volume of the head space K2 in this manner, the introduction port 50b can be positioned above the liquid surface N2 of the contents when the outlet 60c is oriented downward. However, as the height of the pouring member 60 increases, the overall height of the weighing and pouring container also increases.

On the other hand, in the weighing and pouring container of the present embodiment, since the tubular portion 5 is provided with the bent portion 5b extending in the opposite direction to the side where the pouring port 6c is opened, the container main body as shown in FIG. 1 can be tilted, the introduction port 5c positioned at the tip of the tubular portion 5 can be positioned higher. Therefore, even if the height of the pouring member 6 is not so high, the introduction port 5c can be positioned above the liquid surface N2 of the contents and the contents can be poured out in a fixed amount.

In addition, in the weighing and pouring container of this embodiment, since the concave portion (the holding portion 4a, the lower flange 4b, and the peripheral wall 4c) of the main body portion 4 protrudes toward the inside of the mouth portion 1c, the height of the pouring member 6 is reduced. The volume of the weighing chamber K can be increased without changing the height. Therefore, it is possible to more reliably dispense a fixed amount of the contents while maintaining the overall height.

A dispensing container according to the invention is also embodied in the embodiments shown in FIGS. In this embodiment, a body portion 14 is provided in place of the body portion 4 and the tubular portion 5 described above.

The body portion 14 includes a cylindrical holding portion 14a that fits and holds the pipe 2, a flange 14b that extends radially outward from the upper end of the holding portion 14a, and an outer edge portion of the flange 14b that extends downward. A cylindrical lower outer peripheral wall 14c, an annular wall 14d hanging down from the flange 14b on the radially inner side of the lower outer peripheral wall 14c, a female screw portion 14e provided on the inner peripheral surface of the annular wall 14d, and from directly above the holding portion 14a. It has a bent portion 14f that extends horizontally rearward after extending upward, and an introduction port 14g that opens sideways at the tip of the bent portion 14f.

Also in the embodiment shown in FIGS. 3 and 4, since the curved portion 14f extending in the opposite direction to the opening side of the outlet 6c is provided, the introduction port 14g can be positioned higher. Therefore, it is not necessary to increase the height of the pouring member 6 so much. 1 and 2, when the container body 1 is tilted, the introduction port 14g can be positioned above the liquid surface N2 of the contents to pour out a fixed amount of contents. can.

A dispensing container according to the invention may also be embodied in the embodiment shown in FIG. In this embodiment, a tubular portion 15 is provided in place of the tubular portion 5 in the weighing and pouring container shown in FIGS.

The tubular portion 15 includes a cylindrical connecting portion 15a connected to the holding portion 4a, a bent portion 15b extending upward from the connecting portion 15a and then extending rearward in the horizontal direction, and a distal end of the bent portion 15b. It has a folded portion 15c extending downward from the portion, and an introduction port 15d opened at the tip of the folded portion 15c.

In this embodiment, the introduction port 15d can be positioned higher by the bent portion 15b, and the introduction port 15d can be positioned further higher by the folded portion 15c, so that the contents can be poured out in a fixed amount. The possible effect can be obtained more reliably. In forming the tubular portion 15, for example, the tubular portion 15 may be divided into two parts in the thickness direction and the two parts may be combined, or the folded portion 15c may be detachable from the bent portion 15b.

As a modification of the embodiment shown in FIG. 1, the bent portion 5b of the tubular portion 5 is extended along the central axis O like the bent portion 5b' shown in FIG. It may be constructed so as to extend in the opposite direction to the direction in which it extends, and the introduction port 5c' at the tip thereof may be substantially parallel to the liquid surface N2 of the contents. In this case, the introduction port 5c' is less likely to be submerged under the liquid surface N2 of the contents, so that the effect of pouring out a fixed amount of the contents is more assured.
