Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a measuring tool for weighing objects such as powdery materials and granular materials.

[Prior art]

In order to measure a powder, etc., a measuring spoon with a known capacity of the concave portion at the tip is usually used, and the powder is scooped and measured with this spoon. However, if you simply scoop up the powder with a spoon, the powder will build up on the concave part of the spoon.
Because this amount of swelling is not constant each time it is measured, it is not possible to measure it accurately. This is especially a problem for pharmaceuticals, which require high measurement accuracy.

For this reason, in the past, for example, in addition to a measuring spoon, a slotting rod was prepared, and after scooping up the powder with the spoon, the scraping rod was used to scrape off the raised powder to accurately measure the amount. . According to this method, it is possible to fill the amount of powdered material in the amount of the concave portion at the tip of the spoon, and it is possible to accurately measure the powder. However, since the grating rod is separate from the measuring spoon and the bottle containing the measuring object, there is a problem that it is easy to lose it. Furthermore, there are individual differences in the slicing operation with the slitting rod, and there is a risk that the measurement results may vary depending on the operator.

In addition, in order to prevent the scraping rod from being lost, some containers have the scraping rod fixed to the opening of the container. The measuring recess of the spoon was rubbed against this scraping rod to scrape off the raised powder. However, in order to attach the cutting rod to the container, an opening of a certain size or more is required, and for this reason, it has been difficult to apply this method to small containers such as pharmaceutical or portable containers.

In particular, pharmaceuticals have small containers and only a small number of items need to be measured each time, but more accurate measurements are required, and there has been a lack of suitable measuring tools that can accurately measure powdered materials such as pharmaceuticals.

[Purpose of invention]

This invention was made in consideration of the above circumstances,
It is an object of the present invention to provide a simple measuring tool capable of accurately weighing objects such as powdery materials and granular materials.

First, the slide member 20 is moved back so that the slotted portion 22 is located away from the measuring recess 12, as shown by the solid line in FIG. In this state, the object to be measured is scooped out so that it fills the measuring recess 12. Next, when the slide member 20 is moved forward by pressing the non-slip 26 of the slide member 20 with a finger, the excess weighing object that has risen on the weighing recess 12 is removed by the slotted portion 22 and is removed from the weighing recess 12. be discharged. FIG. 1 shows a state in which the excess weighing object raised by the slotted portion 22 of the slide member 20 is completely discharged by the two-dot chain line. Next, when the slide member 20 is moved back to the state shown by the solid line in FIG. 1, the accurately weighed object remains in the weighing recess 12. Then, pour this weighed object into a designated container. Note that since the object to be weighed has already been accurately weighed after cutting, the object to be measured may be opened without retracting the slide member 20.

As described above, according to this embodiment, by simply sliding the slide member back and forth on the measuring instrument main body, the excess object to be weighed can be scraped off and accurately weighed.
Furthermore, compared to the case of using a conventional slicing rod, there is no individual difference in the slicing operation, and no sloppiness occurs in the weighing results.

Note that during repeated weighing, powders, granules, etc. may become trapped between the measuring tool main body 10 and the slide member 20, making sliding operation difficult, or or particulate matter may fall out when opening the weighing object, resulting in inaccurate measurements. To prevent this, a small spring 28 is provided near the sliding protrusion 24 of the sliding member 20, as shown in FIG. Even when the slide member 20 is slid onto the measuring instrument main body 10, there is always a gap provided by the spring 28, so that powdery materials, granular materials, etc. do not get caught. When scraping, press down the slide member 20 with your fingers while scraping, and accurate measurement can be achieved.
