Description

The present invention relates to an instrument for moistening a fingertip in order to facilitate operations such as opening a plastic bag and rolling documents and bills.

Polyolefin plastic bags (commonly called “plastic shopping bags”) that store purchased items in supermarkets, etc. and ultra-thin plastic bags that store wet items separately are difficult to open with dry hands. A sponge containing water is placed and used by customers. However, many consumers are uncomfortable with wet cloths and sponges that an unspecified number of consumers touch with their fingers, and the store side also needs careful management in terms of preventing dryness and hygiene.

In addition, when turning documents or counting banknotes in offices, etc., it is often a detour because it is necessary to put a finger on a sponge for office work moistened with water or put a rubber sack on the finger. ..

Based on the above-mentioned problems, in the following patent document, the applicant supplies only the water necessary for opening the above-mentioned shopping bag etc. to the fingertip, and does not use a wet cloth etc. Proposed.

Utility model registration No. 3199616

The "device for moisturizing fingertips" proposed by the applicant is, as shown in FIG. 3, a water supply unit 1 including a water storage tank 11 and a water supply cap 12 detachably attached to the water storage tank, and a water supply unit 1. A small cap 13 having a water supply hole 131 having a diameter of 3 mm is detachably attached to the bottom of the water supply cap 12, and a fingertip is brought into contact with the water supply hole 131. By doing so, the water in the water storage tank 11 passes through the water supply hole 131 to moisten the fingertip.

However, with the structure of the water supply hole, the amount of water for moistening the fingertips during opening work of a plastic bag or the like and turning up of documents, banknotes, etc. is a little too large and the usability is poor. On the other hand, if the diameter of the water supply hole is reduced in order to reduce the amount of water, the surface of the fingertip may not touch the water even if it touches the water supply hole with the fingertip.In this case, the principle of the capillary phenomenon does not work, and the water is completely absent. There was a problem that it did not come out.

In view of the above problem, in the device for moisturizing the fingertip according to the present invention, by changing the structure and material of the water supply hole of the device proposed in Patent Document 1 and its vicinity, regardless of the amount of water in the tank, a plastic bag It is an object of the present invention to provide an instrument capable of reliably supplying an appropriate amount of water for moistening a fingertip when opening an opening or the like and turning a document or a bill.

In order to solve the above problems, an apparatus according to the present invention has a water supply unit including a water storage tank and a water supply cap detachably attached to the water storage tank, and a main body unit that supports the water supply unit. A thin metal plate having a water supply hole is attached to the bottom of the water supply cap, and a ventilation hole is formed in the vicinity of the bottom of the water supply cap. The water storage hole is formed by bringing a fingertip into contact with the water supply hole. The water in the tank passes through the water supply hole and moistens the fingertip.

The difference from the device of the prior art document, that is, the specific technique of the present invention is: (1) The water supply from the water supply hole of the metal small cap adopted in the device is abolished, and the device is attached to the lower end of the water supply cap. There are two points: water is supplied from a water supply hole provided in an extremely thin metal plate, and (2) a ventilation hole is formed near the bottom of the water supply cap. With this configuration, since the water supply hole portion can be made thin, even if the diameter of the water supply hole is reduced so that the water does not come out too much, the fingertip can surely touch the water. In addition, it is possible to prevent the pressure inside the tank from becoming negative due to the entry of air from the ventilation hole, and the water supply function is stable.

According to the present invention, regardless of the amount of water in the tank, by touching the water supply hole with a fingertip, it is possible to reliably obtain a sufficient amount of water for opening a plastic bag or turning up documents or bills. became.

It is a perspective view of the instrument concerning this embodiment. It is a perspective view which shows the component structure of the instrument which concerns on this embodiment. It is a longitudinal cross-sectional view of a device according to a prior art document (utility model registration No. 3199616). It is (A) longitudinal cross-sectional view, (B) bottom view, (C) partial enlarged view of a metal plate (antibacterial stainless steel plate) of the water supply cap of the appliance of this embodiment.

Regarding the instrument for moisturizing the fingertip of the present embodiment, the difference from the prior art document (utility model registration No. 3199616, hereinafter simply referred to as “previous invention”) will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the device of the present embodiment uses the water supply part 1 and the main body part 2 as basic parts, like the device of the previous invention. Of these, the structure of the main body 2 is the same as in the previous invention. On the other hand, the structure of the water supply unit 1 was as shown in FIG. 3 in the previous invention. That is, a small cap 13 made of metal is detachably attached to the water supply cap 12, and a water supply hole 131 having a diameter of 3 mm is arranged at the bottom of the small cap 13. In this configuration, the water supply amount may be too large depending on the amount of water in the tank, and it was necessary to reduce the diameter of the water supply hole. Conversely, if the water supply hole is too small, the metal thickness of the water supply hole part Due to the pressure inside the tank, the surface of the fingertips could not come into contact with the water, and the water supply itself sometimes became impossible.

On the other hand, in the present invention, the small cap 13 is omitted and the antibacterial stainless plate 5 is attached to the bottom of the water supply cap 12, as shown in FIG. A water supply hole 51 having a diameter of 1 mm is formed at the center of the stainless steel plate 5. The stainless steel plate 5 has a thickness of 0.1 mm, so that the fingertip can easily come into contact with water.

Further, due to the construction method of inserting the stainless steel plate 5 into the resin, the water guiding wall 121 reaching the contacting portion of the antibacterial stainless steel plate 5 is provided with a gradient of about 30 degrees, and the water guiding wall has a diameter of 1 mm penetrating in the vertical direction. The ventilation hole 123 was installed. With this configuration, it is possible to prevent air from entering the water storage tank each time water is supplied into the water storage tank, and even if the diameter of the water supply hole 51 is reduced, the pressure in the tank becomes a negative pressure and water does not come out. I was able to.
