TECHNICAL FIELD OF THE INVENTION
The present invention relates to a powder container capable of measuring and extracting a desired amount of powder.
[0002]
[Prior art]
In order to take out a desired amount of powder in the form of powder or granules such as salt, pepper, chemical seasoning, instant coffee, detergent, etc. from the container, tilt the container and weigh out the desired amount of powder. There is a powder container as described above. This type of powder container is usually provided with a mouthpiece portion communicating with the inside of the container at the upper part of the container, and provided with a measuring tube portion surrounding the mouthpiece portion, and the container body is tilted to After taking out the powder from the mouthpiece into the measuring cylinder, the container body is erected and the measured powder is held in the powder holder, and the container is inclined from this state to tilt the container. Only the weighed powder is taken out of the container.
[0003]
[Problems to be solved by the invention]
In the conventional powder container as described above, the powder taken out from the measuring cylinder by inverting the container body as described above is used when returning the container body to the upright position. Part of the powder returns from the mouthpiece into the container body, and the amount of powder returning varies depending on the properties of the powder, so that accurate measurement of the powder is difficult.
[0004]
The present invention has been made in view of such a problem, and it is possible to accurately measure powder and to take out powder by preventing the powder from returning into the container body. A first object is to provide a simple powder container. It is a second object of the present invention to provide a powder container capable of easily changing a measured value.
[0005]
The present invention adopts the following means in order to solve the above-mentioned problems.
<Summary of the Present Invention> The present invention includes a container main body for accommodating powder, a powder holder for holding the powder taken out from the container main body, and a weighing body for measuring the amount of powder taken out. , The powder holding body is formed at the top of the container body, and has a mouthpiece portion for removing powder, a bottom portion extending around the mouthpiece portion, and surrounding the mouthpiece portion following the bottom portion. An outer cylinder portion; the weighing body has a bottomed weighing cylinder portion surrounding the mouthpiece portion, and an opening communicating with the inside of the powder holder; A predetermined amount of the powder contained in the container body is returned to the upright state after being taken out and measured by the measuring body, and the container body is tilted to take out the measured powder from the opening of the container body. a powder container, the space between these pillar portions are supported by a plurality of pillar portions on top of the mouth tube portion Provided baffle plate forming a powder container to prevent reversion to the container body of the powder after weighing.
[0006]
The outline of the components of the present invention and the points thereof will be briefly summarized below.
(Container body)
In the present invention, the container main body is, for example, a bottle container for storing powder in a powder state or a granule state such as salt, pepper, chemical seasoning, instant coffee, detergent, etc., and may have a wide-open opening at the top. preferable. However, it may be a bottle container provided with a normal mouthpiece. And it can be made of synthetic resin such as PET or glass, but it is preferably made of synthetic resin.
[0007]
(Powder holder)
In the present invention, the powder holding body is for holding the measured powder at the upright position of the container body, and a bottom provided around the mouthpiece of the container body; It is formed from an outer cylinder surrounding the mouth cylinder. It is preferable that the powder holding body is integrally formed, and the powder holding body is incorporated into an opening provided in the container body. However, it is also possible to form a powder holding body by fitting the shoulder around the mouth portion of a normal bottle container to the bottom and fitting an outer tube portion separate from the bottle container to the bottle container. Further, it is preferable that the mouth portion is formed in a cylindrical shape. However, the cross-sectional shape of the mouthpiece may be a polygon such as a quadrangle, a hexagon, or an octagon.
[0008]
(Baffle plate) The baffle plate is provided at the top of the mouthpiece portion constituting the powder holding body and is provided by a plurality of pillar portions so as to form a space between these pillar portions, and the container is inverted. It is intended to prevent the powder from returning to the container body when the container is returned to the upright state after the powder is taken out and measured. However, it is not possible to completely prevent the powder from returning to the container body.Therefore, in order to minimize the amount of powder returning to the container body and to keep the amount constant, the diameter of the baffle plate must be reduced. It is desirable that the disk be substantially the same diameter as the inner diameter of the mouth section. Therefore, it is desirable to set a weighing value in advance in anticipation of the amount of return. Further, the shape of the baffle plate is not limited to a circular shape, and a polygonal shape such as a square, hexagon, or octagon can be selected according to the cross-sectional shape of the mouthpiece.
[0009]
(Measurement body)
The weighing body sets the amount of powder to be taken out of the container body, and has a bottomed measuring cylinder surrounding the mouthpiece provided in the powder holder. The measurement value is determined by the distance between the bottom of the measuring cylinder and the top of the mouthpiece and the internal method of the measuring cylinder. The bottom of the measuring cylinder may be provided on a plate having a larger diameter than the outer diameter of the measuring cylinder, and an opening may be provided near an outer peripheral edge of the plate to communicate with the inside of the powder holding body. preferable.
