Description

INDUSTRIAL APPLICABILITY The present invention touches anywhere when opening the mouth of a thin plastic bag for packing purchased items in shopping at a supermarket, when the cashier staff opens the mouth of the thin plastic bag, or when counting banknotes. The present invention relates to a finger moisturizer used to moisten a human fingertip with a small amount of clean water.

When you try to open the mouth of a thin plastic bag that is used to bag your purchases when shopping at a supermarket, etc., it often happens that your fingertips are dry and you cannot open it well. As a service at supermarkets and the like, wet towels are often placed on the table for packing the purchased items, but it is hygienic because an unspecified number of people use their wet towels with their fingers. It was a problem. In addition, towels that are supposed to be wet are often dry, in which case the fingertips may be moistened by licking their fingertips, which is also unsanitary.
Similarly, when the cashier staff of a store opens the mouth of a thin plastic bag or counts banknotes, the fingertips are often wet with a wet towel or wet sponge, which is also unsanitary. It was
Also, when opening a plastic bag or when wetting a finger to count banknotes, a water droplet with a diameter of 3 mm to 4 mm, that is, about 10 μl of water is sufficient. It is inconvenient because it gets wet and returns.

In order to wet the fingertips, for example, in the fingertip wetting device described in Patent Document 1, an atomizer is attached to the pedestal, and the nozzle is mounted sideways with the nozzle facing upward, with the fingertip held at the position of the nozzle, the atomizer with the palm By pressing the lever of the, the water is atomized from the nozzle of the atomizer by the action of the lever and blows off to wet the fingertips appropriately.

Further, in the fingertip wetting device described in Patent Document 2, a container having an open upper surface is filled with an aqueous solution, the ball-shaped body is floated in the aqueous solution, and a part of the ball-shaped body is projected in an arc shape by a lid. The ball-shaped body is rotated so that the wet portion is touched with a finger, so that the fingertip is appropriately wetted.

Further, in the fingertip wetting device described in Patent Document 3, a container for putting water, a lid that covers the container, and a pressing member that is urged upward through the lid, and the pressing member has a water outlet. A groove narrower than the finger width of the hand is provided in the upper part of the pressing member, and a water discharge port is provided in the groove.By pressing the pressing member, part of the water in the container is discharged from the water discharge port. It is designed to squirt and wet your fingertips.

However, in the finger dampeners disclosed in Patent Document 1, Patent Document 2, and Patent Document 3, all of the fingertips or palms directly touch the finger dampener, so that an unspecified number of people use them. , There was a risk of infection with bacteria and viruses.

In addition to the above conventional hand-wetting device, recently, a device for automatically dropping an appropriate amount of dishwashing liquid detergent by simply holding a dishwashing sponge on the market has been sold. However, the suitable amount of liquid detergent for dishwashing is about 1 to 2 ml, which is about 100 to 200 times more for use for finger wetting, and it is theoretically possible to drop a small amount of water droplets of about 10 μl with the same method. Almost impossible.

On the other hand, commercial dispensers capable of ejecting a very small amount of liquid or viscous fluid are also widely used. Commercial dispensers can discharge various liquids from low-viscosity liquids such as water to high-viscosity liquids such as adhesives from a minimum of several hundred pl (picoliters). Although it is also suitable as a finger wet, the price of the device is remarkably high, and it is impossible to install it on each shopping bag filling table of a supermarket in terms of installation cost.
