No. 64167 is disclosed.

[0003] These containers are provided with a container body used for accommodating the granular material, and a measuring instrument body provided at an upper portion of the container main body, and a lower portion of the measuring instrument body is defined as a powder material storing space. I have. The measuring instrument body has an outlet for the granules, the granules in the storage space can flow into the measuring instrument body and can be temporarily stored, and the temporarily stored granules are The container body can be swung from the swing outlet in a state where the container body is turned left and right in the lateral direction.

For example, as shown in FIG. 4A, a weighing instrument body 101 in a conventional container has a container body 102 as a bottom surface 101a moves from the front to the rear of the container body 102.
And an inflow port 101b is provided on the rear side of the container body 102. This is because when the remaining amount of the granular material becomes small, the granular material is slid down without being deposited on the bottom surface 101a of the measuring instrument body 101 at the time of shaking, and flows into the measuring instrument body 101.

[0005]

However, in the conventional container described above, until the remaining amount of the granular material is reduced, the granular material is ejected even if the amount of rotation of the container body around the left and right sides is small. Would. In the case where the turning amount of the container main body in the left and right direction is small, as shown in FIG. 4B, the bottom surface 101a of the measuring instrument body 101 at the time of the turning goes from the front to the rear of the container main body 102. In the vertical direction. Therefore, the bottom surface 10 of the measuring instrument body 101
Even if the inclination is provided in 1a as described above, instead of allowing the powders S deposited thereon to flow into the measuring instrument body 101, on the contrary, the sufficiently remaining powders S flows into the measuring instrument body 101. Will hinder you.

Further, when the remaining amount of the granular material in the above-mentioned conventional container is reduced, the user intentionally increases the amount of rotation of the container body around the left and right sides, so that the bottom surface of the measuring instrument body is provided. The accumulated powder can be shaken out. But,
The amount of rotation of the container body around the horizontal direction in the horizontal direction, which is necessary for swinging out the granular material from the swing-out opening, is small as long as the remaining amount is sufficient. For this reason, the user becomes accustomed to swinging with a small amount of turning, and when the amount of the granular material becomes small, without increasing the amount of turning, the container can be used without noticing that the granular material remains. May be discarded. On the other hand, if the user intentionally increases the amount of rotation of the container body in the left-right direction, the powder and granules can flow into the measuring device from the bottom surface of the measuring device. It is necessary to greatly increase the amount of rotation of the container body as compared with the case where the amount is sufficient. In such a case, it is necessary to change the way of holding the container body depending on whether the remaining amount is sufficient or small, and there is a problem that the usability is reduced.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a powdery / granular material container with a weighing device which can accurately shake out a granular material by a predetermined amount without waste.

[0008]

According to the present invention, there is provided a container body used for accommodating powder and granules, and a measuring device provided on an upper portion of the container body, and a lower portion of the measuring device is provided with the powder and granules. A powder container with a measuring device, which is a storage space, wherein the measuring device has a powder particle outlet, and the powder material in the storage space can flow into the measuring device and can be temporarily stored therein. Holdable, and the temporarily held powder and granules can be shaken out of the shaker in a state where the container body is turned left and right in the horizontal direction, and the container is placed inside the measuring instrument body. A powdery material discharge path is provided from the front to the rear of the container body as it goes to the upper outlet of the main body, and the bottom surface of the measuring instrument body is directed upward from the front of the container body toward the rear. It is characterized by being inclined.

[0009] According to the container of the present invention, since the powdery material discharge path is provided inside the measuring instrument body from the front to the rear of the container body as it goes toward the outlet above the container body. Even if there is a large amount of body left, the granular material cannot be swung out of the outlet unless the amount of rotation of the container body around the left and right sides is increased. Thereby, the minimum turning amount of the container body when the remaining amount of the powder and granules is sufficient can be equal to the minimum turning amount of the container body when the remaining amount is small, and the powder and granules remain. It is possible to prevent the container from being discarded without noticing that the container is being used. In addition, the bottom surface of the measuring instrument body is inclined so as to go upward from the front of the container body toward the rear of the container body. In addition, it is possible to prevent the difference in the amount of turning of the container main body necessary for flowing the powder and granules from the bottom of the container into the measuring instrument body from increasing. Accordingly, it is not necessary to change the manner of holding the container body when there is a sufficient amount of the granular material and when the amount of the granular material is small, so that the usability does not decrease.

Further , according to the present invention, the inclination of the bottom surface of the measuring instrument body is such that the container body is turned by a minimum amount necessary for swinging the granular material from the front side of the container body at the outlet. sometimes, the bottom surface of the measuring instrument body that is configured to be directed vertically downward toward the rear from the front of the container body. Thereby, the bottom surface can be prevented from obstructing the flow of the granular material into the measuring instrument body.

[0011] The degree of inclination of the bottom surface of the measuring instrument body is preferably set so that when the container body is turned by the above-mentioned minimum amount, the granular material slides down from the bottom surface to the rear side of the container body. Thus, the powdery material can be slid down without being deposited on the bottom surface and flow into the measuring instrument body.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a powdery and granular container with a measuring instrument according to the present invention will be described below.

1 and 2, a container A for a granular material with a measuring device is shown.
Comprises a container body 1 for accommodating powder and granules, and a weighing instrument body 2 attached to an upper opening 13 of the container body 1. The container body 1 is obtained by blow molding, for example, high density polyethylene (HDPE). The measuring instrument body 2 functions as a stopper for the container body 1 when the container is not used.

The container main body 1 has a body 12 surrounding the powder and granular material storage space located below the measuring instrument body 2, and a neck 14 forming the opening 13. On the outer periphery of the neck portion 14, a male screw 14a for screwing and attaching the measuring instrument body 2 is provided.

The body 12 has a bottom wall 11 and front, rear, left and right extending upward from the periphery of the bottom wall 11 (in FIG. 2, the lower side is the left side of the container body 1 and the upper side is the right side of the container body 1). The left side is the front of the container body 1 and the right side is the rear of the container body 1). The upper portion of the rear wall portion 12d is inclined so as to be directed upward and toward the front wall portion 12c, and the opening 13 is arranged to be biased toward the front wall portion 12c.
Each of the left and right side walls 12a and 12b is held by the user's finger as shown by a chain line in FIG. Note that the left and right side walls 12a,
It is preferable to provide a portion depressed inward of the container from the surrounding portion in each of the 12b.

The measuring instrument body 2 is, for example, 2
An outer cylinder 21 having a function of measuring a granular detergent of 0 g or less and being screwed to the outer periphery of the neck portion 14 of the container body 1.
And an inner cylinder 22 integrated with the outer cylinder 21.
The inner cylinder 22 is fitted into the opening 13 of the container main body 1 to prevent the powder and particles in the container main body 1 from flowing out of the opening 13.

The container body 1 between the upper and lower parts of the inner cylinder 22
An inflow port 22a is provided in a half peripheral portion on the rear side of. In this way, the container A is turned around in the left and right direction, so that the powder and granules in the container body 1 can flow into the measuring instrument body 2 from the inflow port 22 a on the rear side of the container body 1.

A partition 24 is provided in the inner cylinder 22. The partition 24 has an upper end reaching the upper end of the outer cylinder 21, and a lower end extending below the inflow port 22 a and above the lower end of the inner cylinder 22. Thereby, the upper part of the inside of the measuring instrument body 2 is moved to the rear inflow space 25 for allowing the powder and granules to flow into the measuring instrument body 2 for measurement, and from the inflow space 25 to the measuring instrument body 2. It is divided into a discharge space 26 on the front side for discharging the inflowed and temporarily stored powders. The volume of the inflow space 25 is set larger than the volume of the granular material S temporarily stored in the measuring instrument body 2.

The outer cylinder 2 corresponding to the upper end of the discharge space 26
At one location, an outlet 27 for ejecting the granular material S is provided, and a hinge-type lid 28 for opening and closing the outlet 27 is provided on the outer cylinder 21. The hinge axis of the lid 28 is on the rear side of the container body 1 and extends in the left-right direction.
In addition, the lid 28 is provided with an annular convex portion 28a that fits into the swing outlet 27 when closed, thereby increasing the airtightness of the container A when not in use. This is particularly effective in the case where the granular material S has hygroscopicity or dislikes moisture from the viewpoint of maintaining the fluidity of the granular material S which affects the measurement accuracy.

The upper part of the discharge space 26 provided inside the measuring instrument body 2 is a powder discharge passage 26a.
The shape of the partition 24 and the outer cylinder 21 is set such that the powder / particle discharge passage 26a goes from the front to the rear of the container body 1 as it goes to the outlet 27 above the container body 1.

The inner cylinder 22 constituting the bottom surface of the measuring instrument body 2
Of the container body 1 is inclined upward from the front of the container body 1 to the rear.
Due to the inclination, as shown in FIG. 3, when the container body 1 is turned by a minimum amount necessary to swing out the granular material S from the front side of the container body 1 in the outlet 27, the bottom surface 22 b of the container body 1 It goes vertically downward as it goes from the front to the back of the container body 1. Further, the degree of inclination of the bottom surface 22b is set such that when the container body 1 is turned by the above-described minimum amount, the granular material S slides down from the bottom surface 22b to the rear side of the container body 1. That is, in the upright state where the container A is placed on the horizontal surface via the bottom wall portion 11 as shown in FIG. 1, the angle α formed by the bottom surface 22b of the measuring instrument body 2 with respect to the horizontal surface is shown in FIG. In this manner, in such a state that the container body 1 is turned by the minimum amount, the bottom surface 22b is set so as to secure an angle β to be formed with respect to the horizontal plane in order to slide down the granular material S. The angle β is determined according to the minimum turning amount of the container body 1 and the frictional resistance between the bottom surface 22b and the granular material S, and can be obtained by an experiment.

According to the container A having the above structure, as shown in FIG. 3, when the container A is rotated left and right and laterally and tilted so that the outlet 27 and the front wall portion 12c face downward, the container body 1 The granular material S inside flows into the inflow space 25 from the inflow port 22a. Here, since the volume of the inflow space 25 is set to be larger than the volume of the granular material S temporarily stored in the measuring instrument body 2 as described above, the container A is erected as shown in FIG. When returned to the state, the granular material S exceeding the amount temporarily stored in the measuring instrument body 2 flows out of the inlet 22a into the body 12, and a certain amount of the granular material S remaining below the inlet 22a. It is temporarily stored in the inner cylinder 22. Next, when the container A is rotated again in the left-right direction, a predetermined amount of the granular material S that has reached the discharge space 26 out of the granular material S temporarily stored in the inner cylinder 22 by the previous operation is shaken. At the same time, the granular material S in the body 12 is swung out from the outlet 27 and the powder S
From the inlet space 25.

In the measuring instrument body 2, there is provided a powdery material discharge passage 26a extending from the front to the rear of the container body 1 as it goes to the outlet 27 above the container body 1.
Even when the amount of the granular material S is large, the granular material S cannot be spouted from the outlet 27 unless the amount of rotation of the container body 1 around the left and right sides is increased. Thereby, the minimum turning amount of the container main body 1 while the remaining amount of the granular material S is sufficient,
The minimum turning amount of the container main body 1 when the remaining amount is reduced can be made equal, and the container A can be prevented from being discarded without noticing that the granular material S remains. Further, the container body 1 depends on whether the remaining amount of the granular material S is sufficient or small.
It is easy to use because there is no need to respond by changing the holding style. Also, the bottom surface 22b of the measuring instrument body 2
When the container body 1 is turned by the minimum amount, the container body 1 moves vertically downward from the front to the rear of the container body 1, so that the bottom surface 22 b hinders the inflow of the granular material S into the measuring instrument body 2. Can be prevented. Further, by sliding the powder S down to the rear side of the container main body 1 without being deposited on the bottom surface 22b, the powder S can flow into the measuring instrument body 2 from the inflow port 22a.

The present invention is not limited to the above embodiment. For example, the present invention may be applied to a weighing instrument that is capable of swinging out a temporarily suspended powdery material from a swing outlet by turning the container body around the left and right sides and allowing the powdery material to flow in from the rear side of the container body. The structure of the container main body is not particularly limited as long as the measuring instrument body can be provided on the upper portion. For example, the container main body may have a handle. Further, the inflow ports of the measuring instrument body may be provided at left and right side positions.
