Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a tool for opening and closing a lid screwed to a container.

[0002]

[Prior art]

 As an opening / closing tool to be used when the lid that is screwed into a container such as a bottle is tight and difficult to open, a pair of semi-circular holding parts made of metal that hold the outer peripheral surface of the lid is provided with handles. It is well known that a lid opening tool such as a plier attached to a lid, or a simple belt-like rubber ring that fits tightly on the outer peripheral surface of the lid to prevent slipping.

[0003]

[Problems to be solved by the device]

 The lid opening tool can open the lid securely, but it is expensive, heavy, has a large storage space, and is inconvenient to carry around for opening and closing the lid of bottled food such as camping and hiking. .

The band-shaped rubber ring is easy to carry, but in the case of a rubber ring smaller than the diameter of the lid, it is dealt with by the elongation of the rubber. They cannot be in close contact and cannot open all lids of various sizes.

Further, the band-shaped rubber ring is fitted to the outer peripheral surface of the lid and grips by hand to apply a rotational force to prevent slipping between the lid and the hand. The rotational force that is transmitted to the is a localized concentrated stress that acts on the gripped part of the hand, and the rotational force does not act evenly over the entire circumference of the lid, so it is considerably stronger to open a tightly closed lid. It requires a turning force and cannot be easily opened with a light force.

In view of the above-mentioned conventional problems, an object of the present invention is to provide a container lid opening / closing tool which is lightweight, convenient to carry, and capable of easily opening and closing the lid with a light force.

[0007]

[Means for Solving the Problems]

 A feature of the present invention to achieve the above object is to open and close the lid by tightening it around the lid screwed to the container. The lid is made of woven fabric, leather, synthetic resin or the like. A ring through which the band is inserted is attached to one end in the longitudinal direction of a band made of a tough material that is flexible and has low stretchability, and a roller is attached to this ring in an axial direction parallel to the width direction of the band. The structure is characterized in that a large friction material such as soft rubber is provided on one or both sides of the strip.

Further, the lid is opened and closed by being wound around the lid screwed to the container, and is made of a flexible and tough material such as woven cloth, leather, synthetic resin, and the like with little stretchability. A ring through which the band is inserted is attached to one end of the band in the longitudinal direction, a roller is mounted on the ring in an axial direction parallel to the width direction of the band, and the roller is opened at the other end of the band in the longitudinal direction. The structure is characterized in that a mouth hole is provided and a large friction material such as soft rubber is provided on one or both sides of the strip.

[0009]

[Embodiment of device]

 Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 is a strip made of a tough material such as woven cloth (twill weave cloth), leather, synthetic resin or the like which is flexible and has little stretchability.

A ring 2 made of metal or synthetic resin, through which the strip 1 is inserted, is attached to one end of the strip 1 in the longitudinal direction, and a roller 3 is attached to the ring 2 in the width direction of the strip 1. It is mounted in parallel axis directions. The roller 3 may be rotatably attached to the ring 2, or may be attached to the ring 2 made of a material having a good slip such as Teflon.

Further, a large friction material 4 such as soft rubber is provided on one or both sides of the strip 1. The large friction material 4 is formed by applying a plurality of small pieces in parallel on one side or both sides of the strip 1 in parallel at regular intervals, or by applying a layer on one side or both sides of the strip 1 in the longitudinal direction. May be.

Further, an opening hole 5 is provided at the other end portion (tip portion) on the opposite side of the one end of the strip 1 to which the ring 2 and the roller 3 are attached.

As for the container lid opening / closing tool having the above-mentioned structure, for example, as shown in FIGS. 3 and 4, the large friction material 4 applied to both sides of the band 1 may have either side. However, in the case of one side, the surface on which the large friction material 4 is applied is wound around the entire outer peripheral surface of the lid 7 screwed into the container 6, and the other end (tip) of the band 1 is covered with the lid 6. From the outer peripheral surface side, it is inserted into the ring 2 and hooked on the roller 3 to reverse the direction of rotation in which the screw of the lid 7 loosens, and then pull in that state.

As a result, the belt 1 is smoothly pulled by the roller 3 and tightened over the entire outer peripheral surface of the lid 7, and the large friction material 4 is brought into close contact with the entire outer peripheral surface of the lid 7. Then, the pulling force at the other end of the strip 1 acts evenly on the entire outer peripheral surface of the lid 7, and is distributed over the entire outer peripheral surface of the lid 7 as a rotational force in the direction in which the screw of the lid 7 loosens. It is possible to easily loosen the lid 7 that has been acted on and tightened with a small pulling force.

When the lid 7 is firmly tightened and the screw of the lid 7 is not loosened by the pulling force by the hand, insert a rod, a screwdriver or the like into the opening hole 5 at the other end (tip portion) of the band 1 and then A large pulling force can be applied with a small force and can be easily loosened by bringing the end into contact with the container 6 and causing a lever or the like to leverage.

The above is the case of loosening the screw of the lid 7. However, when the lid 7 is tightened again after the contents are taken in and out of the container 6, the lid 7 screwed to the container 6 is stripped as described above. 1 is wound around the entire outer peripheral surface of the lid 7, the other end (tip) of the band 1 is inserted from the outer peripheral surface side of the lid 6 into the ring 2, hooked on the roller 3, and the screw of the lid 7 is tightened. Turn over and pull in that state.

As a result, the lid 7 can be firmly tightened so that the lid 7 is prevented from leaking due to the rotational force acting in the tightening direction opposite to the loosening direction. At this time as well, by inserting a rod or a screwdriver into the opening hole 5 at the other end (tip portion) of the strip 1 and bringing the tip end into contact with the container 6 to cause the rod or screwdriver to leverage. A large pulling force can be applied with a small force, and it can be easily and firmly tightened.

If the band 1 is set to have a length corresponding to the diameter of various lids, there is no problem unless the lid has an excessively large diameter. In the case of a lid that cannot be accommodated by the length, another strip for connection can be prepared and passed through the opening hole 5 to connect.

This container lid opening / closing tool can be applied to other applications. For example, in furniture, it can be used to tighten and loosen the legs of a table, the legs of a kotatsu, etc. when screwing things in and out. Further, even in a case where a tent is screwed to a tent by camping or the like, it can be used for tightening and loosening the screw connecting portion.

Moreover, the band 1 is flexible, tough, lightweight and compact, and can be stored in a small space, so that it can be used not only at home but also for camping, hiking, and other carrying purposes. Is also convenient.

[0021]

[Effect of device]

 As described above, the present invention has the following special effects. Wrap a strip with a large friction material around the entire circumference of the lid that is screwed into the container, and insert the other end (tip) of the strip from the outer circumference of the lid into the ring. By hooking on the roller and reversing the direction in which the lid screw loosens or tightens, and pulling in that state, this pulling force acts evenly on the entire outer peripheral surface of the lid, and the lid screw The lid can be easily loosened and tightened with a small pulling force because it is used as a rotating force in a loosening direction or a rotating force for tightening, which is distributed over the entire outer peripheral surface of the lid. Insert a rod or screwdriver into the opening hole at the other end (tip) of the strip, and bring the tip of the rod into contact with the container so that the rod or screwdriver can leverage it to pull it with a small force. A force can be applied, the lid can be easily loosened and tightened, and when the length of the band is insufficient, another band can be connected to the opening hole to extend the length. The band is flexible, tough, lightweight and compact, and can be stored in a small space. It is convenient and inexpensive not only for use at home but also for camping and hiking. Can be provided.
