Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a fixed-quantity container.

"Prior Art" For example, a fixed-quantity shaking container shown in Japanese Utility Model Publication No. Sho 42-20606 is known, and the container has an opening at the upper end of the container body fitted with a peripheral wall of a tapered member having an upper small diameter and an upper end opening. In addition, a peripheral wall is hung from the peripheral edge of the top wall, a plurality of through holes are bored in the outer peripheral portion of the top wall, and a cylindrical member that hangs a partition wall cylinder of the lower surface opening from the back wall portion of the inside of each of the through holes is formed. It is known that the lower part of the peripheral wall of the tapered member is fitted to the outer surface of the peripheral wall of the tapered member so that the mouth of the upper end of the tapered member is located at the central portion of the lower end opening of the partition wall.

"Problems to be solved by the invention" In the above-mentioned conventional fixed-quantity shake-out container, the contents stored in the container are passed through the mouth of the upper end of the tapered member and put into the partition wall of the cylindrical member to be weighed. Then, the container is returned to the upright position to transfer the measured stored items to the storage chamber between the outer surface of the tapered member and the inner surface of the cylindrical member, and the container is inverted to move the stored items. , The container is provided so as to be shaken from a shake hole formed in the outer peripheral portion of the top wall that closes the upper end surface of the peripheral wall, but since the measuring chamber formed by the partition tube is located above the upper end opening of the tapered member, the container When the container is returned to the upright state, a part of the contents stored in the weighing chamber will return to the inside of the container through the opening at the upper end of the tapered member, and the contents transferred to the storage chamber will be shaken out by inverting the container. At that time, part of it is returned to the weighing chamber again. Therefore, there is a drawback that the weighing and the starting are inaccurate.

The idea is that the items weighed are not returned to the container body, and the items stored in the storage chamber are not returned to the weighing chamber.
It is provided so that the weighing and shaking can be accurately performed.

"Means for Solving the Problem" The container body 1 that erects the mouth and neck, and the large bottomed and top opening that hangs into the container body 1 by fitting the upper end tube portion onto the inner surface of the upper end of the mouth and neck portion. The large-diameter tubular portion 5 is composed of a large-diameter tubular portion 5 and a small-diameter tubular portion 15 having upper and lower end surface openings fitted to the inner surface of the upper portion of the large-diameter tubular portion. A plurality of suitable first window holes 10 are formed at substantially equal intervals, and a protruding projection portion 11 projecting inwardly of the cylindrical portion is vertically provided on the inner surface of the lower cylindrical wall portion vertically below the first window hole. The upper end surface of the portion is formed as an inclined surface 12 that descends inward, and the small-diameter cylindrical portion 15 has a cylindrical wall portion facing the first window hole 10 that is closed at the upper end so that the outer surface is concave and the inner surface is convex. And the left and right side wall portions 16a, 16a of the groove wall 16 are extended downward to form the groove wall 16 of the lower surface opening.
The outer side surfaces of the left and right sides of 1 are brought into contact with each other, and the second window hole 18 is formed by the extended portions of the both side wall portions, the lower end of the inclined surface 12 and the lower end edge of the groove wall intermediate plate portion 16a. To first window 10
Through the first passage 4 into the groove wall 16 and the second passage extending from the inside of the groove wall through the second window hole 18 to the bottom of the large-diameter cylindrical portion 5.
19 and the projecting protrusions 11 and 11 from the bottom of the large-diameter cylindrical portion.
The third passage 20 is formed so as to pass through between the outer surfaces of the groove walls 16 and 16 and between the outer surfaces of the groove walls 16 and 16, and reach the opening of the upper end surface of the large-diameter cylindrical portion.

[Operation] When the container body is inverted from the state shown in FIG. 1, the contents inside the container are inside the measuring chamber A formed by the inside of the groove wall 16 of the small-diameter cylindrical portion 15 from the first window hole 10 as shown in FIG. Enter and be weighed. When the inverted state is returned to the upright state, the stored items in the groove walls 16 pass through the second window holes 18 and enter the storage chamber B formed by the bottom of the large-diameter cylindrical portion 5. When the container is turned upside down again, the contents stored in the storage chamber B are shaken out from the upper end opening of the large-diameter cylindrical portion through the protruding protrusions 11 and 11 and the groove walls 16 and 16, and at the same time. As described above, the contents are put into each groove wall 16 and weighed.

“Example” 1 is a container body in which a mouth / neck portion 2 is erected. The small-diameter cylindrical portion 3 is further erected from the upper end of the mouth-neck portion. This is to provide a gap as the first passage 4 between the later-described first window hole and the inner surface of the mouth-neck portion. It is possible to increase the diameter of the cylindrical wall portion of the large-diameter cylindrical portion above the first window instead of forming it.

The large-diameter tubular portion 5 is fitted into the inner surface of the upper end portion of the mouth / neck portion, and hangs down into the container body 1. The large-diameter cylindrical portion has a bottom and is open at the upper end surface, and has an outward flange 6 that is engaged with the top surface of the container body mouth at the upper end of the cylindrical portion. The upper cylindrical wall portion has a large diameter portion 7, and the lower portion thereof has a small diameter portion 9 via a taper portion 8. The large diameter portion 7 has a plurality of suitable first window holes 10 formed at substantially equal intervals. Further, a protruding projection 11 projecting inward of the cylindrical portion is vertically provided on the inner surface of the lower cylindrical wall portion vertically below the first window hole 10, and the upper end surface of the protruding portion is made an inclined surface 12 descending inward. .
The overhanging protrusion may be formed with a concave portion 11a on the outer surface side as shown in the figure.

The small-diameter cylindrical portion 15 is fitted into the upper portion of the cylindrical wall of the large-diameter cylindrical portion 5. The small-diameter cylindrical portion has upper and lower end surface openings, and a cylindrical wall portion facing the first window hole 10 has a concave outer surface and a convex inner surface.
The upper end face is closed to form the groove wall 16 having the lower face opening. The left and right side wall portions 16a, 16a of the groove wall extend downward so that their lower end portions are in contact with the outer surfaces of the left and right side portions of the overhanging protrusion 11. In the illustrated example, a lateral plate 17 is attached between the lower ends of the left and right side wall portions, and the upper surface of the lateral wall is a second inclined surface continuous with the inclined surface 12 on the upper surface of the protruding portion. The lower end edge of the middle portion 16b of the groove wall 16 may be located below the lower edge of the first window hole 10 described above, and the lower end edge and the left and right side walls 16a, 16a extended portions and the lower end edge of the inclined surface 12 may be located. A second window hole 18 is formed between

With the above configuration, the second passage 19 extending from the inside of the groove wall 16 to the inside of the bottom portion of the large-diameter tubular portion 5 through the second window hole 18, and between the protruding portions 11 and 11 and the groove wall extending from the bottom portion of the large-diameter tubular portion. A second passage 20 is formed through 16 and 16 and above the upper end opening of the large-diameter cylindrical portion 5.

[Advantage of the Invention] The present invention is configured as described above, and the first window hole 10 formed in the groove wall 16 as the inlet of the measuring chamber is formed in the upper cylindrical wall portion of the large diameter cylindrical portion 5 that hangs down inside the container body. Since it is installed, that is, as shown in FIG.
Since the container is not opened to the lower side of the measuring chamber as in the conventional case, when the container is erected from the state shown in FIG. 2, the items stored in the measuring chamber can be moved into the storage chamber B almost accurately, and The second window hole 18 serving as an outlet is provided vertically on the lower edge portion of the groove wall intermediate plate portion 16b, the extended portions of both side portions of the groove wall, and the inner surface of the lower cylindrical wall portion vertically below the first window hole. The third passage 20 is formed by the lower end of the inclined surface 12 formed by the upper end surface of the overhanging protrusion 11, and the third passage 20 for overhanging the stored items from the storage chamber B is provided between the overhanging protrusions 11 and outside the groove wall 16. Since it is formed in the space, it is less likely that the stored item shaken out through the third passage will return to the measuring chamber through the second window hole 18, and thus the amount of measurement and the amount of shakeout can be compared with the conventional case. Can be done accurately.
