Description

  The present invention is a disposable finger sack capable of preventing bacteria attached to a fingertip from adhering to food when grabbing food with a fingertip of a hand and preventing the fingertip from being soiled by food or the like. About.

Traditionally, various confections including snacks such as biscuits, donuts, potato chips, fast foods such as hamburgers and fried chicken, pizzas, etc. Foods that are difficult to eat with chopsticks and forks are eaten by grabbing them directly with your hands.
If you grab food directly with your hand (fingertips) and eat it, the bacteria attached to your hand or fingertip will adhere to the food, and the fingertips may become dirty with the food. It has been conventionally done by washing the fingertips with water or soap, wiping them with a wet towel, etc., or grabbing and eating the food using a paper napkin etc. so that fingers and hands do not touch the food directly Yes.
However, it is not always possible to completely remove the bacteria on the fingers even after washing or wiping with a towel, that it is necessary to wash hands and fingers again after a meal, There are problems such as being touched and unsanitary. Further, since the paper napkin is not formed to fit the fingers, there is a problem that the food cannot be grasped well when eating various shapes of food.

In order to solve such a problem, there has been proposed a finger cover in which two pieces of vinyl shaped like one finger are overlapped and bound in a bag shape (Patent Document 1).
In addition, as a fingertip sack that can pinch snack foods of various shapes, two large and small finger sacks (large: forefinger and middle finger, small: thumb) are joined together using a band-shaped member with a hinge function and integrated with the palm. A fingertip sack that is easy to attach and detach has been proposed (Patent Document 2).
Furthermore, a finger sack for a knob having a male formed of an elastomer such as silicone rubber has also been proposed (Patent Document 3).

However, the finger cover shown in the above-mentioned Patent Document 1 requires a bag-shaped finger cover to be widened and attached to the fingertip, and the finger cover is troublesome to install, and the back surface of the finger cover (the surface in contact with the finger) ) Is a smooth surface, there was a problem that when you grabbed the food, it slipped out of the finger in some cases and could not be grasped well.
Moreover, since the fingertip sac shown in Patent Document 2 uses a material having an appropriate tension as a material to be used, a member having a hinge function is placed on a table or the like in a state where the member having a hinge function is stretched when not in use. In addition, the insertion port of the finger sack faces and the insertion port of the finger sack is positioned parallel to the surface of the table, so that there is a problem that it is difficult to insert a finger and it cannot be mounted instantaneously with one hand.
Furthermore, since the finger sac for a knob shown in Patent Document 3 is not disposable, it needs to be cleaned after use. Since the shape of the finger sack is complicated, it takes time to clean, and the manufacturing cost increases.

  The present invention has been made in view of the above circumstances, and the problem to be solved is a finger sack for protecting food from bacteria and the like adhering to the finger and eating hygienically without contaminating the finger. In addition, it is easy to put on and take off even when the finger size (thickness) is different between men and women, providing a disposable finger sack that can hold food firmly without falling out of the fingers and can be mass-produced at low cost. There is to do.

As a result of intensive studies in order to solve the above problems, the present inventors have determined that the finger sack as a whole is a finger sack provided with a thumb pocket and an index finger pocket as pockets into which fingers can be inserted at both ends of the belt-like base. It was found that when the finger sack is attached to a finger, the food can be firmly grasped without soiling the finger even when the food is rich in oil.
Further, the present inventors embossed both the inner surface of the pocket, i.e., the surface in contact with the fingertip of the band-shaped base and the surface in contact with the fingertip of the pocket portion, so that when the finger sack is attached to the finger, Appropriate friction occurs between the surface of the belt-shaped base that contacts the fingertips and between the finger and the surface of the pocket that contacts the fingertips. I found out that I can do it.
In particular, the present inventors attach the finger sack by providing a finger thickness adjusting means formed by heat-welding the thumb pocket and the index finger pocket to an appropriate portion of the belt-like base in the form of dots. When the finger is thick, the heat-welded part can be peeled off to widen the pocket, and it is found that a finger sack can be worn even with various finger thicknesses such as adults / children, men / women It was.
Furthermore, the present inventors can easily attach to other fingers such as the thumb and forefinger when using the finger sac, and have a shape that does not hinder the movement of the finger with the finger sack when picking food or the like. As a result of the study, the band-shaped base (finger sack) can be formed so that the straight line connecting the center point of the finger sack (band-shaped base) and the respective ends of both ends intersect at an angle of 160 ° to 170 °. It was found that it was most suitable, and the present invention was completed.

That is, the present invention is a disposable finger sack that is used by putting it on a finger when eating with food in hand.
It is composed of a band-shaped base, a thumb pocket provided on one end thereof, and an index finger pocket provided on the other end so that the opening faces the opening of the thumb pocket,
The band-shaped base has a knob part on one end side and a knob part on the other end side for gripping food with the thumb and index finger, and a connecting part connecting these two knob parts,
The band-shaped base is made of a polyolefin sheet, of which at least the knob portion is embossed on one side,
Each sheet of the thumb pocket part and the index finger pocket part is composed of a polyolefin sheet embossed on one side, and
Both the inner surface of the thumb pocket and the surface of the knob facing the embossed surface are both embossed surfaces, and the inner surface of the index finger pocket and the surface of the knob facing the embossed surface are both embossed surfaces. The pocket portion and the band-shaped base knob portion, and the index finger pocket portion and the band-shaped base tab portion are each provided with a finger thickness adjusting means that is formed in a severable manner and is separable. ,
It relates to disposable finger sack.
In the finger sack, an angle formed by a straight line extending from the center point of the connecting portion of the band-shaped base to the tip of the knob on one end side and a straight line extending from the center point to the tip of the knob on the other end side is 160 ° to It is preferable that the band-like base is formed in a shape having an angle of 170 °.

The finger sack of the present invention can be easily attached to the finger with one hand (simply opening the thumb and forefinger) when eating food such as confectionery or fast food with a hand. Even if there is, it is possible to grab food firmly with the power of a child without soiling the finger and slipping with oil.
In addition, the finger sack of the present invention is embossed on the inside of the pocket, that is, the surface in contact with the finger, so that moderate friction is generated between the finger and the finger sack, preventing it from slipping off the fingertip during use. Can grasp the food firmly.
In particular, the finger sac of the present invention can be easily worn even by fingers of various thicknesses for both young and old by the finger thickness adjusting means provided on the finger sack. When a person with a thick finger uses, the finger thickness adjusting means is peeled off and separated to prevent a situation where the finger can be widened and the finger cannot be inserted. On the other hand, when a person with a thin finger uses the finger without removing it, the part into which the finger is put can be used as it is thin, and the situation where the finger sack comes off the finger due to being too thick can be prevented.
Furthermore, the finger sack according to the present invention does not require the pocket of the finger sack to be greatly expanded when the finger sack is used, and it is not necessary to greatly bend the finger to be fitted to the finger insertion part of the finger sack. It is easy to attach to these fingers only by opening the index finger, and it does not hinder the movement of the finger wearing the finger sack when picking food or the like.
And since the finger sack of this invention is disposable, it is hygienic.

In addition, since the finger sack of the present invention has a thin and flat shape when not in use, it can be stored in layers, and a plurality (several dozens) of finger sacks are stacked and packed in a box or bag.・ Can be stored. If a box or the like in which these finger sacks are packed together is placed on a table for eating in a restaurant or at home, it can be used easily during meals, and it is customary to eat food hygienically even with a hand grip.
And since the bag etc. which wrapped the finger sack can be carried, a finger sack can also be used in the case of the meal in the outdoors or a restaurant.
