JPH1095475A - Constant volume-discharging inversion cap for powdery material - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a cap which is easily handled on using it and which lessens the contents finally left in a container and relatively simplifies the assembling of the constiting members, by attaching the bottom member to the lower end of the cap body so that an opening/closing member and a measuring cup can be rotated to both right and left. SOLUTION: A container equipped with a constant volume-discharging inversion cap 10 is not required to invert the container erected normally, on using it, but only required to tilt it. After discharge of the contents, when the container is returned to the inverted condition, the contents 30 flow naturally in a measuring cup 300 from the container body 20 by a specified volume, and hence, the handling thereof is extremely easy on using it. When a lug 301 for rotation of the measuring cup 300 is reversely rotated, while it is not used, the opening 111 of the top plate 110 of the cap body 100 is closed by the top plate 210 of the opening/closing member 200, and the notch 132 of the peripheral wall 131 of the cap body is closed by the peripheral wall 310 of the measuring cup 300.

[0008]

According to the present invention, an inverted cap for quantitatively discharging powder according to the present invention (10).
As shown in FIG. 1 (a), the container body (2
0) is used while attached to the mouth and neck (21). When not used, the top plate (1) of the cap body (100) is used.
Since the opening (111) of (10) is closed by the top plate (210) of the opening / closing member (200), no contents are contained in the measuring cup (300). As shown in FIG. 1B, the cap body (10
0) Notch (13) of measuring cup housing (130)
When the rotation knob (301) of the measuring cup (300) projecting from 2) is rotated, the measuring cup and the opening / closing member (200) engaged with the measuring cup rotate, and the top plate (110) of the cap body is rotated. Opening (111) of the opening and closing member and the opening (211) of the opening / closing member overlap, and the contents (30) in the container body (20) are shifted from the tip of the inclined plate (230) provided below the opening of the opening / closing member. From the inflow port (240) into the measuring cup. The inflowing content is measured and quantified by the volume of the measuring cup. Further, the notch (132) of the peripheral wall (131) of the cap body and the notch (311) of the measuring cup match. Then, the container is inserted into the cap body and the cutout portions (132 and 31) of the measuring cup.
When tilted to the side 1), as shown in FIG. 1 (c), the quantified contents (30) are discharged, and at the same time, the contents in the container main body flow through the opening / closing member (200) due to the inclination of the container. It stagnates near the entrance (240). As described above, the container equipped with the powder quantitative discharge inverted cap of the present invention is different from the conventional powder quantitative discharge container, and it is necessary to use the container by inverting the container from the upright state when using. When the container is returned to an inverted state after being discharged, the contents (30) from the container body (20) naturally flow into the measuring cup (300) as shown in FIG. And is quantified, so that handling during use is extremely easy. When not in use, when the rotating knob of the measuring cup is rotated in the opposite direction, as shown in FIG. 1A, the opening (111) of the top plate (110) of the cap body (100).
Is closed by the top plate (210) of the opening / closing member (200),
Notch (132) of peripheral wall (131) of cap body
Is closed by the peripheral wall (310) of the measuring cup.

Further, since the fixed amount discharge cap for powder according to the present invention is used by being attached to the mouth and neck of the container body in an inverted state in which the contents are stored, the cap is not discharged to the end inside the container body. The remaining amount of the remaining contents is extremely small.

The inverted cap for quantitatively discharging powder according to the present invention comprises four components: a cap body, an opening / closing member, a measuring cup, and a bottom member. With the rotating knob of the measuring cup protrudingly inserted into the measuring cup receiving portion of the cap body, and then the measuring cup with the opening / closing member is attached to the bottom member so that it can rotate to the left and right. Yes, the assembly of the components is simple.

The fixed-capacity powder inverted cap of the present invention, in which the opening of the opening / closing member is divided by a partition wall and the measuring cup is divided by the partition wall from the notch to the inside, is opened and closed by a rotary knob. Depending on the degree of rotation of the member and the measuring cup, the fixed amount of discharge can be selectively changed.

[0020]

According to the present invention, when the container is used in an inverted state by attaching the fixed amount discharge cap for powder of the present invention to the mouth and neck of the container body containing the powdery contents, the conventional fixed amount discharge for powder is performed. Compared to opening the cap lid when using the container and then inverting the container from the upright state and discharging the quantified contents, simply opening the cap with the rotary knob and tilting the container The quantified contents can be discharged simply by performing the above operation. Further, when the container is again turned upside down, the contents naturally flow into the measuring cup and are quantified. Then, the cap can be easily sealed by rotating the rotary knob. As described above, the fixed-quantity discharge inverted cap for powder of the present invention is a cap that is easy to handle at the time of use.

Further, since the container main body for accommodating the contents is always in an inverted state, the remaining amount that remains without being completely discharged into the container main body is extremely small. Easy.

By dividing the interior of the opening / closing member and the measuring cup by a partition wall, the constant discharge amount can be selectively changed at the time of use.
