Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a lid loosener for opening screwed lids of bottles and the like.

(Prior Art) Screw-on lids for bottles and the like are tightly tightened to maintain a sealed state for a long period of time.

In the figure, the person who loosens the lid is usually the bottle body 1.
0 firmly, and move the lid 11 in the direction of arrow A or lid 1.
1 firmly and rotate the bottle body 10 in the direction of arrow B.

(Problems to be Solved by the Invention) Since the lid 11 is tightly screwed onto the bottle body 10, a considerable amount of force is required to loosen the lid 11 for the first time, and it is difficult for an elderly person to open the lid.

(Means for Solving the Problems) The present invention provides a means by which even a weak elderly person or a child can easily loosen a tightly screwed lid, and its structure is as follows. be.

A nut member with a left-handed thread is fixed to the tip of an arm that protrudes above the holder from a support provided on the side of the holder, and a bolt is provided with a threaded part that is compatible with the threaded part of the nut member. Screw the parts together,
This is a lid loosener in which a bolt rotating means is provided at the base end of the bolt member, a pressing plate is fixed to the tip of the bolt member, and high friction is imparted to the lower surface of the pressing plate and the upper surface of the pedestal.

High friction properties can be provided to the lower surface of the press plate and the upper surface of the pedestal by the rubber material attached to each.

(Operation) A container with a tightly screwed lid is placed on the pedestal, and the bolt member is rotated by the bolt rotation means to lower the pressing plate and come into contact with the lid, and as it is, If torque is applied in the direction of rotation, the direction of rotation of the press plate is in the direction of loosening the lid, so the frictional force between the press plate and the lid overcomes the frictional force between the screwed part of the lid and the container body. The lid moves slightly in the direction of loosening, and the bolt member fills in the backlash of the threaded portion with the nut member.

The high friction properties imparted to the bottom surface of the press plate and the top surface of the pedestal increase the frictional resistance between the press plate and the lid or between the container body and the pedestal. In addition, if the rubber material is used to provide high friction, the slight increase in the height of the container due to the loosening of the lid can be suppressed by the rubber material. The slight compression can compensate for the loosening of the threaded portion between the nut member and the bolt member.

(Example) An example of the lid loosener according to the present invention will be described based on the accompanying drawings.

Reference numeral 1 designates a pedestal, and a high friction material 1a such as a rubber material is adhered to the surface of the pedestal. 2 is a pillar;
Its base is integrally or integrally provided with the cradle 1, and the arm 3 is fixedly or pivotally supported rotatably with a pin 3a at the tip thereof, and the arm 3 is shown in the figure as shown in FIG. A stopper 2a is provided to limit clockwise rotation. A nut member 4 whose core is substantially aligned with the center of the pedestal 1 is fixed to the tip of the arm 3. A bolt member 5, which descends under the action of a left-hand thread 5a, is screwed into the nut member 4 with a slight backlash. A pressing plate 6 having a high friction material 6a such as rubber affixed to the front surface thereof is fixed to the lower end of the bolt member 5, and a handle 7, which is a means for rotating the bolt, is removably attached to the square part of the base end. It is provided.

Next, the effect will be explained.

Turn the handle 7 clockwise when viewed from above in the figure to raise the pressure plate 6, or rotate the arm 3 around the pin 3a in the direction of arrow C to release the container 12.
Place it on the receiving stand 1, then lock the arm 3 on the stopper 2a, position the pressing plate 6 above the lid 11, and use the handle 7 to loosen the pressing plate 6 and the lid 11 in the direction of arrow A. Lower it while rotating it in the direction. By continuing to rotate the handle 7, the high friction material 6a comes into contact with the top surface of the lid 11, and by further applying torque to the handle 7, the frictional force between the high friction material 6a and the top surface of the lid 11 causes the lid 11 and the container body 10 to When the lid 11 overcomes the frictional force of the screwed portion, the lid 11 is pulled in the direction of the arrow A by the press plate 6 and moves slightly, and the lid 11 is loosened.
Although it rises slightly, this rise is due to the bolt member 5
It is absorbed by the backlash between the nut member 4 and the nut member 4.

The high friction material 6a attached to the press plate 6 is
The high friction material 1a that suppresses slipping with the lid 11 and is adhered to the pedestal 1 suppresses slipping with the container 12. Furthermore, by using rubber materials as the high friction materials 1a and 6a, a slight increase in the height of the container 12 due to loosening of the lid 11 can be compensated for by compression of the rubber material.
In combination with the backlash between the bolt member 5 and the bolt member 5, good absorption is achieved.

Once the lid 11 is loosened, the handle 7 is rotated in the opposite direction, the pressing plate 6 is separated from the lid 11, the container 12 is taken out from the cradle 1, and the lid 11 can then be easily removed from the container body 10.

Incidentally, it goes without saying that the rotation of the pressing plate 6 can be achieved by connecting a reversible motor to the bolt member 5 instead of the handle 7.

(Effect of the invention) As can be understood from the above explanation, according to the lid loosener of the present invention, the bolt member descends while rotating in the direction of loosening the lid, and the pressing plate strongly contacts the lid. Since the lid can be loosened, even weak elderly people and children can now easily loosen tightly screwed lids on bottles and the like.
