Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening and closing device for manually opening and closing a circular screw-in lid.

[0002]

2. Description of the Related Art In daily life, when opening a screw-type lid such as a tightly closed bottle, it is usually necessary to press the lid tightly with a damp cloth and turn it tightly. Further, the lid is opened by heating for a short time.

[0003]

However, for a weak person such as a young person or an elderly person, the lid is not easily opened by the above-described method, and it is often difficult to open the lid. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and aims to provide a screw-type circular lid opening / closing device capable of easily opening and closing a tightly closed lid even by a person with weak power.

[0004]

SUMMARY OF THE INVENTION The present invention relates to an opening and closing device for manually opening and closing a circular screw-in lid, a handle for opening and closing operation, a band for winding around the lid, and a tip of the handle. And a stopper for rotatably mounted near the one end of the band, and the stopper has an insertion hole for forming a ring through which the other end of the band is inserted. And a lid opening / closing tool comprising a locking means for removably locking the tip end of the band passing through the insertion hole to the handle.

[0005] The handle is a handle portion which is held and held by a hand to be opened and closed. The band is to be wound around a lid having an arbitrary diameter, and one end of the band is fixed to the stopper. The stopper is rotatably mounted near the tip of the handle, and one end of the band is locked. The stopper has an insertion hole for inserting the other end of the band to form a ring. Further, a locking means for detachably locking the tip end side of the band passing through the insertion hole, that is, a portion ahead of the ring, to the handle is provided.

As a result, the following effects are obtained.
That is, first, the band is inserted into the insertion hole to form a loop of the band, the lid portion is positioned inside the loop, and a portion of the band is pulled beyond the loop of the band to wind the band around the lid. In this state, the distal end side of the band, that is, a portion ahead of the loop is locked to the handle so that the size of the loop does not change even when a force is applied.

Next, while turning the handle with the hand while fixing the main body of the article to which the lid is attached, a force for turning the lid works.
The rotation force acting on the lid is larger than the radius of the lid by the handle because the rotation radius of the operation unit is increased by the principle of leverage, and becomes stronger. As a result, when the band is set to the cover in the direction in which the rotation direction is the direction in which the cover is opened, the cover is easily opened, and when the band is set so that the rotation direction is in the direction to close the cover, The lid can be strongly tightened. In principle, the longer the handle, the greater the degree of amplification of the force.

It is preferable that the portion of the band that is wrapped around the lid is made of a non-slip material.
It is also preferable to use a flexible material so that it can be easily wound around the lid.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. In this example, as shown in FIGS.
A handle 10 for opening and closing the lid 81, a band 20 for winding around the lid 81, and a band 20 rotatably mounted near the tip of the handle 10. And a stopper 30 for fixing one end of the head. The stopper 30 has an insertion hole 31 through which the other end of the band 20 is inserted to form the ring 21, and further, the distal end side of the band 20 into which the insertion hole 31 is inserted is detachably engaged with the handle 10. Coupling portions 11 and 23 as locking means.

The above configuration is further supplemented by a description. The connecting portions 11 and 23 are so-called magic tapes (registered trademark).
, Consisting of a female loop and a male hook. That is, the surfaces are pressed against each other so that they are easily tightly bonded to each other, and after the bonding, the bonding is maintained in a state where the resistance to the separating force applied in the lateral (parallel) direction is extremely large. Further, the two can be relatively easily separated by pulling in the direction perpendicular to the coupling surface. Usually, the connecting portion 11 on the handle 10 side is a female loop material, and the connecting portion 23 on the band 20 side is a male hook material.

The stopper 30 is provided in the small hole 15 of the handle 10.
(FIGS. 3 to 6) A shaft 33 attached to the shaft 33 and a horizontal shaft 3 at a position facing the shaft 33 to which an end of the band 20 is attached.
And 5. Then, the stopper 30 swings freely around the shaft 33. 7 and 8 show examples of the shape of the stopper 30. FIG. On the other hand, the band 20 is formed of a material having a moderate strength, a surface that is hard to slip, and a high flexibility.

This device operates as follows to open and close the lid 81. That is, first, as shown in FIGS. 1 and 2, the band 20 is inserted into the insertion hole 31 to form the loop 21 of the band 20,
The lid 81 is located inside the loop 21. Next, the portion of the band 20 beyond the loop 21 is pulled, and FIG.
As shown in the figure, the band 20 is wound around the lid 81, and in this state, the connecting portion 23 on the distal end side of the band 20 is pressed against the connecting portion 11 of the handle 10 and locked, and this state is maintained. . In the figure, reference numeral 80 denotes a main body of a container to which a lid 81 is attached.

Next, when the main body 80 is held and a force is applied to the handle 10 in a counterclockwise direction as indicated by an arrow in the figure, a force T for rotating the lid 81 counterclockwise as indicated by an arrow is applied. Since the turning radius at the position where the force is applied by hand becomes larger than the radius of the lid 81 by the length of the handle 10, the turning force T is amplified by the principle of leverage and becomes strong. As a result, the lid 81 is easily opened.

On the other hand, when it is desired to strongly tighten the lid 81, as shown in FIGS. 5 and 6, the mounting direction of the lid 81 to the ring 21 is set to the opposite side, and the force is applied in the clockwise direction as shown in FIG. Is added, the lid 81 can be strongly tightened. And Toride 1
As the length of 0 is longer, the degree of amplification of the lid opening force or lid tightening force increases. It should be noted that the lid opening tool of the present invention is not limited to the illustrated example described above, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.
For example, in the present example, the handle 10 is illustrated as a straight rod, but the handle 10 may be partially or entirely curved such that the handle 10 is easy to operate, or may be bent or uneven in thickness. You may do it.

[0015]

As described above, according to the present invention, it is possible to obtain a circular lid opening / closing tool that enables even a weak person to easily open and close a tightly closed lid.
