[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention protects the operator's safety while preventing the contamination of the measurement liquid due to damage when measuring the alcohol concentration in an aqueous solution containing alcohol and when measuring the specific gravity of a liquid having a lower specific gravity than water. Therefore, it relates to a liquor meter or hydrometer made of a material that is not easily damaged.

[0002]

[Prior art]

 Conventionally, as a method for easily measuring the alcohol concentration in an aqueous solution containing alcohol, a method using a liquor meter and a method using a hydrometer are generally used.However, all of these instruments are made of glass and made of plastic. There is only a hydrometer made of polycarbonate (made by Nalgene) for liquids having a heavier specific gravity than water, and there is no plastic liquor meter and hydrometer.

[0003]

[Problems to be solved by the device]

 When measuring the alcohol concentration in an aqueous solution using a conventional alcohol meter or hydrometer, the alcohol meter and hydrometer may be damaged because they are made of glass, and careful handling is required for safety. Met. In addition, when adjusting the concentration of a large amount of alcohol solution, there was a problem that a glass liquor meter or a hydrometer was damaged and the alcohol solution was contaminated, and a large amount of alcohol solution had to be discarded. It is an object of the present invention to provide a safe and damage-free liquor meter and densitometer that replaces conventional glass products.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present inventors have completed the present invention by making a float by using a plastic material such as polyethylene which is easily worked. That is, the present invention provides (1) a liquor meter including a weight portion, a float portion, and a scale portion or a hydrometer for liquids having a specific gravity of less than 1, wherein the outer shell is made of plastic. The present invention relates to (2) the liquor meter or the hydrometer of (1), wherein the ratio of the weight portion to the floating portion is 1.3-0.8 ml of the floating portion to 1 g of the weight portion.

Next, the present invention will be described with reference to the drawings. Fig. 1 shows the plastic material used in the production of plastic sake meter and hydrometer, and Fig. 2 shows 1 to 3 of Fig. 1a vertically connected with a small lead ball at the bottom and a weight part. It is an example of a liquor meter and a pycnometer prepared by providing. FIG. 3 shows an example of a liquor meter and a pycnometer, which are produced by connecting three a's of FIG. 1 in parallel and putting a small lead ball in the central tube to provide a weight portion. In addition, Fig. 4 shows that e of Fig. 1 is worked by using a gas burner or heat gun, etc., a small lead ball is put in the bottom part to provide a weight part, and cotton is packed in the constricted part above it to move the small lead ball. It is an example of a liquor meter and a pycnometer produced by preventing the above, and the ratio of the weight portion and the floating portion is preferably 1.3 to 0.8 ml per 1 g.

In the present invention, the shape of the liquor meter and the specific gravity meter is not particularly limited, and various shapes such as those shown in FIGS. 2, 3 and 4 can be obtained by using a wooden mold or a mold without using the commercially available material shown in FIG. It is also possible to make a plastic material in a shape to make a liquor meter and a hydrometer. Further, a commercially available plastic container other than that shown in FIG. 1 and plastic pipes or balls having different thicknesses can be appropriately combined to produce a sake meter. As a method of making plastics, it is possible to use heat as well as glass work, but it is also possible to use adhesives. For details, it is recommended to refer to “Polyethylene work in the laboratory” (Kodojin).

[0007] Examples of plastics used for producing the sake meter and the hydrometer include polyethylene, polypropylene, polystyrene, polymethylpentene, polycarbonate, polyvinyl chloride, Teflon, and the like, and combinations thereof are also possible. is there. Also, small iron balls or iron powder can be used instead of small lead balls. Further, the adhesive used for the plastic working is not particularly limited as long as it is a quality that is not easily deteriorated by alcohol, and examples thereof include cyanoacrylate-based adhesive, styrene-butadiene-based adhesive, and epoxy resin-based adhesive. In addition, the adhesives for plastics described in "Adhesives for polymer chemistry" in "Chemical Handbook Application" (edited by the Chemical Society of Japan) can also be used. The scale of alcohol concentration was given to the sake liquor meter on the basis of alcohol solutions of various concentrations adjusted separately, but it is appropriate to give about 3 levels to each liquor meter for every 10% concentration. The scale of the hydrometer was given to the hydrometer based on variously adjusted specific gravity solutions, but one hydrometer had a specific gravity of 0.030 to 0.060 and a scale of 0.001 to 0.002. It is appropriate to give.

【Example】

 The present invention will be described in detail with reference to examples, but the present invention is not limited thereto.

Example 1 A polyethylene spoid was connected at its bottom to another spoid whose tube portion was appropriately cut, and the bulge portion was used as a floating portion and the elongated portion was used as a scale portion. Cut out the bulge of the spoid, fill it with small lead balls, and connect the weighted part with adhesive. Wrap a thin piece of paper around the tube at the tip, cover the outside with a transparent plastic tube, and attach it to the upper part of the bulge of the spoid. At this time, the inner tube can be cut and removed. Use an adhesive to make sure that the liquid does not enter from the connection area. Next, prepare 40%, 50% and 60% alcohol solutions separately in a cylinder, and float the prepared floats in it one by one, and place the surface position in each solution in a tube. After writing on the paper inside, the tip of the tube was sealed or sealed with an adhesive to complete the sake meter.

Example 2 A swelling portion of a polyethylene-made spoid is cut out, small lead balls are packed in the bottom portion, and the weight is prepared by bonding with an adhesive. This weight is re-bonded to the top of the polyethylene drop that was cut off earlier. Next, prepare two floats that are made by cutting the tube portion of the polyethylene spoid and sealing it, and attach one to each side of the float that was made earlier to form the float, and then use the thin tube in the center. Put a paper cylinder in the shaped part and use it as a graduation part to make a float. Next, the sake meter was completed in the same manner as in Example 1 using the separately prepared alcohol solutions having the concentrations of 40%, 50% and 60%.

Example 3 The end of a polyethylene tube was sealed, and the upper part of the tube was constricted to form a shape close to a sphere, and the tube was again held with a volume two to three times that of the sphere. To constrict and stretch it over into a thin tube. Next, fill the ball at the bottom with a small lead ball, and stuff it with cotton up to the constricted part above it so that the small lead ball does not move. Next, a paper cylinder was placed in the upper thin tubular portion to make a float, and a sake meter was completed in the same manner as in Example 1 using separately prepared alcohol solutions having a concentration of 60%, 70% and 80%. It was

Example 4 A hydrometer was prepared in the same manner as in Example 3, and a specific gravity solution of 0.910 to 0.960 prepared separately was used to complete a hydrometer in the same manner as in Example 1.
