Description

  The present invention relates to an opener for easily opening a lid by rotating a lid of a container such as a can or a bowl.

  Some cans and bowls containing food, daily necessities, etc. can be opened and closed by rotating screws. These lids are firmly screwed together to improve the storage stability of the contents, and it is often difficult to open the lids. In addition, in the course of use, the lid often becomes hard due to solidification of contents or changes in internal pressure, even if the intention is not tight. In particular, women, children, the elderly and the disabled are often in trouble because the lid cannot be opened.

  For this reason, for example, as disclosed in Patent Document 1 (Japanese Utility Model Laid-Open No. 57-126393), there is one in which a rubber sheet is placed on a lid and the lid is rotated. However, this type increases the coefficient of friction and makes it difficult to slip, but there is a limit rather than increasing the rotational force (torque) itself.

For this reason, Japanese Patent Application Laid-Open No. 2000-281185 proposes a technique for winding a belt around a lid and rotating the lid.
In this technique, as shown in FIG. 15, the opener 1 winds a belt 3 around a lid and rotates the handle 2. In this technique, it is necessary to adjust the belt 3 so that the belt 3 is tightly wound around the lid by grasping the handle 2 with one hand and pinching the end portion 34 of the belt 3 with the other hand. Thereafter, the hand holding the end 34 is released, and the handle 2 is rotated by grasping the body of the container 5 with the hand.

However, this technique requires both hands for the operation of the opener 1 itself, and there is a problem that the hands are not rotated to hold the container, and it is unstable and poor in operability. Further, even if the belt 3 is adjusted, there is a problem that the belt 3 is loosened as soon as the end portion 34 is separated. Also, there is a problem that the operation method is complicated and difficult to use unless used.
