[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-insulating gripper suitable for use in a cup for an instant food or a drinking cup of a beverage vending machine (hereinafter referred to as "vending machine").

[0002]

2. Description of the Related Art Conventionally, as a cup having this kind of gripping tool, for example, there is a cup described in Japanese Utility Model Laid-Open Publication No. 52-105585. According to this conventional technique, a concave portion having an arbitrary shape is formed on an outer surface of a cup body made of paper, a thin synthetic resin, or the like, and an upright handle is located in the concave portion, and the handle is formed upright. As shown in FIG.

The handle of this cup easily protrudes from the peripheral surface of the cup, and is unstable. Therefore, when a large number of cups stacked in the vending machine are automatically moved one by one by a robot arm in the vending machine, Adjacent cups are separated and difficult to adopt. For this reason, as a heat-insulating gripping tool used by a user in addition to a paper cup suitable for vending machines, there is a conventional one described in, for example, Japanese Utility Model Registration No. 3044075.

According to this conventional technique, a frame body including a locking portion, a grip portion, and an abutting portion is formed by plastic injection molding, and the grip portion has a substantially U shape which is laterally viewed in a side view. The index finger of the user is hung on the hollow portion, the upper outer wall is pressed with the thumb, the lower outer wall is supported by the middle finger, and can be lifted, and the upper end of the grip portion is connected to the locking portion,
The lower end of the grip portion is connected to the contact portion, the contact portion contacts the outer wall of the cup, and has a curved portion of an appropriate length above the outer wall, and the inner surface of the curved portion is locked. A holding space is formed at an appropriate distance from the outer wall of the cup, and the upper side wall of the cup inserted from below into the holding space is held between the outer wall of the locking portion and the upper end of the curved portion. The upper end portion of the curved portion is locked to the upper end portion of the cup by sandwiching the inside of a flange formed by bending outward, and the upper end portion of the curved portion has an appropriate distance from the stopper block of the locking portion above it. The locking portion has a substantially inverted U-shape. The upper portion of the outer wall and the curved portion of the contact portion maintain an appropriate distance from each other, and a relatively large-area arc is formed at the lower end of the outer wall. A stop block is formed inside the upper wall of the locking portion, and the stop block is fitted to the upper end of the curved portion of the contact portion. The cup is clamped in the clamping space between the curved portion of the contact portion and the outer wall of the locking portion, and the inside of the flange at the upper end of the cup is locked at the upper end of the curved portion of the contact portion. , By holding the outside of the cup flange with the stop block of the locking part, it can be held without swinging the cup,
It is said that the outer wall of the locking portion provides the action of tightening the cup due to the gravity of the beverage in the cup, so that the cup can be held stably and can be used for gripping the user and preventing burns. is there.

[0005]

The above-mentioned prior art is difficult to additionally provide with a vending machine as an accessory of a drinking cup due to a thick three-dimensional object formed by plastic molding, and furthermore, the opening edge of the cup is rounded outward. Since it is a gripping tool for curled curl flanges, it can not be used for cups without flanges, of course, and it can not be applied to cups with flanges that just protrude horizontally and protrude the cup flange, many essential and serious There is a problem.

In addition, the portion referred to as the locking portion for the curl flange clamp in this conventional example needs to be made precisely with a precise dimensional accuracy corresponding to the above-mentioned curl flange. The second problem is that various types of grippers having different locking part shapes are required, and management, maintenance and inspection in all systems, such as production, storage, distribution, sales, purchase and use, are complicated and uneconomical. There is also.

Further, in this conventional example, since the plastic handle does not rot, the used handle is incinerated. The high heat at the time of incineration shortens the life of the furnace and causes pollution due to generation of harmful gas. There is also a problem in that so-called “environmental hormones” such as bisphenol A and dioxin are caused by fillers and softeners mixed in the molding plastic.

According to the present invention, in order to eliminate the above-mentioned problems, the cup gripper to be additionally used for the cup is made of strip-shaped cardboard obtained from natural resources, thereby eliminating the need for plastic molding of the gripper. Eliminate garbage pollution, eliminate paper waste by cutting sheets from long paper, make it easy to add and provide as an accessory to the cup, and support the lower thin cup by inserting it into the gripper cylinder Therefore, it is an object of the present invention to enable interchangeable use with a cup slightly different in size and a cup having a different flange shape.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide a gripping tool provided in a lower thin cup, in the lengthwise direction of a sheet made of thick western paper into a square or a flat V-shaped strip. A gripping piece is connected to each other via a diagonal fold line extending upward on both sides to form a deployment structure of a gripping tool, and the sheet is bent in the length direction against the rigidity of the sheet, and the gripping pieces are bent obliquely. By joining together at the joint from the wire, a lower thin cylinder is formed and the gripping pieces are joined together, and the lower diameter of the cylindrical body is smaller than that of the upper inner method. And the lower thin outer peripheral surface of the cup is received almost vertically by the lower inner peripheral surface of the cylindrical body, and the cup can be gripped by the gripping piece.

[0010]

Embodiments of the present invention will be described with reference to the drawings. First, in the basic embodiment of the present invention, as shown in FIG. 1, when a grip is provided in a lower thin cup, a thick rectangular paper such as a thick kraft paper is used to make a rectangular strip as shown in FIG. 1 (a). Outwardly oblique fold lines 2 and 2 are formed symmetrically on both sides in the longitudinal direction of the sheet piece 1 having rigidity, and elongated gripping pieces as shown in FIG. The unfolded structure of the cup gripping tool according to the present invention is constituted by connecting 3 and 3 in series.

Next, the sheet 1 is folded in two in the longitudinal direction against its rigidity as shown in FIG. As shown in FIG. 3C, the lower thin cylindrical body 5 is formed in a three-dimensional manner in which the gripping piece 3 side is slightly inclined upward when viewed from the side as shown in FIG. Then, a lower thin cup 6 having a smaller diameter and a larger upper diameter than the upper inner method is inserted into the cylindrical body 5 as shown in FIG.
The lower part of the inner peripheral surface of the cup 6 is received on the lower inner peripheral surface of the cylindrical body 5 in a state where the cylindrical body 5 is inclined as shown in FIG. 6 is a heat insulation gripping device for a cup according to the present invention, which can grip the gripping pieces 3 and 3 in the palm-fixed state with fingers a substantially vertically as shown in FIG.

The heat-insulating gripper for a paper or plastic molding cup according to the present invention thus manufactured can be flattened by folding and folding the three-dimensional object shown in FIG. , Easy to provide as a cup accessory. Then, the purchaser simply spreads the flat thing as shown in FIG. 1 (c) to make it three-dimensional, and places the lower thin cup 6 in the cylindrical portion 5 in a good fit state as shown in FIG. 1 (d). Even if the cylindrical body 5 is obliquely inserted into the cup 6 as shown in each of these figures, it can be fitted and supported.
As shown in (d), the gripping piece 3 can be stably gripped with the finger a, and the hot beverage or food in the cup 6 can be consumed or eaten without heating the finger a.

The joining portion 4 of the gripping piece 3 may be glue-bonded, but may be made of a heat-adhesive resin such as a polyethylene coat layer applied to the surface of the sheet 1 or the joining surface of the two sheets. Heat-sealing adhesion of a coat layer or a laminate layer may be used, and each of these joints 4 may be formed into a M-shaped fold or “Gazette” fold and joined to form a gripping piece 3 of four sheets of polymerized sheets. By folding the joint part projecting and protruding about twice as much as the previous example to form a gripping piece 3 of four sheets, the gripping pieces 3 of these two members are more tough than the double one of the previous example. Become.

Further, since the cylindrical body 5 is flexible so as to be deformable in the circumferential direction, the cylindrical body 5 can be covered well with, for example, a square cup or a square deep dish container in addition to the circular cup of the previous example. An outer flange 6a is formed by curling the opening edge of the outer surface of the cup 6 outward as shown in FIG. 2, and the cylindrical body 5 may be covered on the cup 6 up to the outer flange. The body 5 may be partially spotted and adhered, and the gripping piece 3 may be formed in a rectangular shape according to the outer shape of the cup 6 as shown by a chain line in FIG.

Since the heat-insulating gripper according to the present invention thus produced is widened upward, the gripping pieces 3 can be bent along the outer peripheral surface of the cup, so that a large number of heat-insulating containers can be polymerized and accumulated without being bulky. The food maker puts the cooked dried food and other items (not shown) into the cup 6 and then airtightly attaches a lid plate to the upper edge of the cup 6 before shipping.

The purchaser partially peels off the lid plate from the cup 6, pours hot water into the instant food in the cup, closes the lid, waits for about 3 minutes, and holds the gripping piece 3 by hand as shown in FIG. In this case, even if the user grips the gripping piece 3 by hand and eats it, the tubular body 5 is positioned so as to be obliquely and firmly fitted into the cup 6, so that it may slip off. Not
Moreover, the heat emitted from the cup 6 can be cut off by the gripping pieces 3,
The food in the cup 6 can be eaten while holding the cup 6 by hand with confidence.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to apply the present invention to a flat, large, and heavy cup such as a large instant noodle, as shown in FIG.
A predetermined range portion is upwardly spread and attached to the palm through a diagonal folding line 2 to form a gripping piece 3, and also on the opposite side of the location where the gripping piece 3 is formed, similarly to the example shown in FIG. The gripping piece 3 is formed from the fold line 2 of FIG. 3, and a cylindrical body 5 having oblique fold lines 2 and 2 extending upward and downward in the left and right directions as shown in FIG. As shown in FIG. 4, a flat large-sized ramen cup 6 is fitted into the body, the lower thin outer peripheral surface of the cup is received by the lower thin inner peripheral surface of the cylindrical body 5, and the two gripping pieces 3, 3 are held with both hands. It may be a heat-insulating gripper for a cup that can be gripped.

[0018] In this case, even a flat large and heavy cup can be stably and reliably carried in the manner of holding both hands.
In this example, the cylindrical body 5 can be inserted into the cup 6 substantially orthogonally, and the cylindrical body 5 in this example is formed by folding both ends of the two arc-shaped strip-shaped sheets 1 upward. , It is possible to obtain a two-handed heat-insulating gripper comprising a lower thin cylindrical body 5 having two gripping pieces 3 and 3.

Further, the strip-shaped sheet piece 1 in the present invention is formed in a flat inverted V-shape as shown in FIG. 5, and extends upward on both sides in the longitudinal direction of the sheet piece 1 through oblique folding lines 2 and 2, respectively. The gripping pieces 3 and 3 are connected in series to form a deployment structure of the gripping tool as shown in FIG. 5, and the sheet 1 is bent in the length direction against its rigidity so that the gripping pieces 3 and 3 are inclined with each other. As shown in FIG. 6, the joints 4 are joined from the fold line 2 to form the lower thin cylindrical body 5, the holding pieces 3, 3 are joined together, and the cylindrical body 5 is separated from the upper inner side by the inner method. As shown in FIG. 7, the lower thin outer peripheral surface of the cup 6 is substantially vertically received by the lower thin inner peripheral surface of the cylindrical body 5 and the cup 6 is fitted into the lower thin cup 6. May be used as a heat-insulating gripper for a cup that can be gripped by the gripping piece 3.

Further, as shown in FIG. 1 (c), a "hit" mark m is printed on a surface of the sheet 1, which is an inner surface of the cylindrical body 5, by characters or symbols at a ratio of about one sheet per 1,000 sheets. By doing so, the final user, such as an instant cooked food, can use an award such as “XX Hot Spring Invitation” for the work of separating the folded two-fold sheet 1 attached to the food from the joint surface with his / her finger or the like. , It is possible to give a kind of joyful thrill, and to give the end user an opposition to the work of making the tubular body 5 from the two sheets, thereby improving the willingness to purchase. You can also.

Furthermore, the aspect ratio of the insulated gripper according to the present invention can be arbitrarily selected according to the cup, but it can also be used as a gripper for a flatter or longer vertically long insulated container as compared with the previous example. Further, when the cylinder 5 is fixed to the cup 6 by spot attachment or the like so as to be inseparable, for example, a polyethylene laminate layer (a so-called poly-laminate layer) is formed on the inner surface of the cylinder 5 or on the outer surface of the cup 6. If a paper having a heat-adhesive synthetic resin layer adhered thereto as in (1) is used, the two can be spotted and bonded only by partially heating and pressing the cylindrical body 5 against the cup 6.

Incidentally, a polyethylene coat layer or a poly-laminate layer may be applied to the inner surface of the cup 6, and the lower portion of the cylindrical body 5 may be stopped at a position substantially higher than the bottom of the cup 6. In addition, the lower part of the cylindrical body 5 can be reinforced by extending below the bottom of the cup and curling the periphery of the lower edge of the cylindrical body 5, and the outer flange 6a of the cup 6 is not always required. In forming the outer flange 6a, the opening edge of a well-known paper cup may be curled by a curling machine, or may be a flat flange slightly extended in the lateral direction without curling. 6a and the cylinder 5
It is possible to further prevent the cup from slipping out of the cup.
