Abstract

PURPOSE: A screw cap opening/closing device is provided to rotate a screw cap together when the screw cap opening/closing device rotates around the screw cap when the screw cap is fixed by a holder and an adjustment holder. CONSTITUTION: A screw cap opening/closing device comprises a lever(11), a link(14), a holder(16), and an adjustment holder(17). One end of the lever is fixed to an upper case(20) and the other end is connected to a pin A(12). The lever rotates using the pin A(12) as a shaft. The link is connected between the connection part of the upper case and the pin A by a pin B(13). The holder is connected to the line by a pin C(15). The adjustment holder holds the screw cap with the holder.

Description

Screw Cap Opener {Screw Cap Opener}

The present invention relates to an opening and closing device that allows the user to open and close the screw cap even weak or handicaps.

In general, the screw cap is opened and closed with bare hands, in the case of the elderly or disabled, especially in the case of the first opening PET bottle, there is a problem that can not easily open the lid.

The opening and closing device of the screw cap, which has been proposed so far, has a problem that it is bulky and requires a separate power source or a battery.

Another proposed type of opening and closing device is to wrap around the screw cap with an elastic body or a toothed ring and turn by hand, which does not sufficiently compensate for the limited strength and movement of the elderly and the disabled.

Pliers or spanner-type opening and closing device has a problem that the hand turning the screw cap is not located on the axis of rotation of the screw cap is off the axis of rotation so that the act of turning the screw cap is unnatural.

The problem to be solved by the present invention is to provide an opening and closing device that can easily open and close the screw cap by a weak or disabled user without using a separate power source such as an electric motor.

In order to achieve the above object, the present invention has one end functioning as a handle and the other end connected to a pin, the lever rotating around the pin; A link having one end connected to another pin between a portion serving as a handle in the lever and a pin that is a shaft; A holder connected to a pin at the other end of the link and performing a linear movement according to the rotation of the lever; It is provided with a screw cap opening and closing device which is located opposite the holder and including an adjustment holder for tightening and fixing the screw cap with the holder.

The screw cap is positioned between the holder and the adjustment holder.

When the user pushes the handle of the lever to rotate the lever about the axis, the pin which becomes the axis of the lever; A pin connecting the lever and the link; The pin connecting the link and the holder is gradually positioned in a straight line, so that the holder makes a linear motion to tighten the screw cap located between the adjusting holder and the holder.

Preferably, the pin is the axis of the lever; A pin connecting the lever and the link; The pin connecting the link and the holder is gradually positioned in a straight line according to the rotation of the lever, and when the lever is fully rotated, the pin connecting the lever and the link is positioned slightly beyond the straight line.

Through this configuration, the holder and the adjustment holder are still tightening the screw cap even if the lever is completely pressed and then the lever is removed.

Preferably, it is preferable that the adjustment holder can be moved and fixed in a linear direction to adjust the distance between the adjustment holder and the holder.

Through this configuration, it is possible to use the opening and closing device according to the invention in the screw cap of various diameter sizes.

Preferably, a material having a large coefficient of friction or a material having a large elasticity is preferably used in the holder and the adjusting holder in contact with the screw cap.

According to the present invention, it is easy to open and close the screw cap by a user with weak hand strength or impaired movement, such as the elderly and the disabled, without using a separate power source.

As shown in FIG. 1, the screw cap opening and closing device 10 according to the present invention has one end fixed to the upper case 20 and the other end connected to the pin A 12 to connect the pin A 12. A lever 11 rotatable axially; A link 14 connected to the upper case 20 of the lever 11 by a pin B 13 at a position between the connecting portion of the lever 11 and the pin A 12; A holder 16 connected to the link 14 by a pin C 15 to perform a linear movement according to the rotational movement of the lever 11; Located on the opposite side of the holder 16 includes an adjustment holder 17 for holding the screw cap with the holder 16.

2 shows the lever 11 in a state before the lever 11 is pressed; Link 14; Holder 16; The connection of the adjustment holder 17 is shown with the bottle and the screw cap.

Pin A 12 is the axis of rotation of the lever 11, pin B 13 is connected to the lever 11 and the link 14 in a rotatable state, pin C 15 is the link 14 and The holder 16 is connected to each other in a rotatable state.

The holder 16 is restricted in the linear direction by the lower case 19, so that the linear movement is performed in accordance with the rotational movement of the lever (11).

3 shows the lever 11 in a state after the lever 11 is pressed; Link 14; Holder 16; The connection of the adjustment holder 17 is shown with the bottle and the screw cap.

The pin A 12 is fixed in position, the pin B 13 is in a circular motion around the pin A 12 as the lever 11 rotates, and the pin C 15 performs a linear motion. Done.

As a result, the holder 16 moves to tighten the screw cap with the adjustment holder 17.

Preferably, pin A 12; Pin B 13; Pin C 15 is gradually positioned in a straight line as the lever 11 rotates, and when lever 11 is fully rotated, pin B 13 slightly passes over the straight line, whereby pin A 12 and pin C It is preferable to position it slightly below the straight line which connected (15).

Through this configuration, even after the lever 11 is fully pressed, the holder 16 and the adjustment holder 17 are tightening the screw cap as they are even when the force of pressing the lever 11 is removed.

Preferably, the adjustment holder 17 is preferably movable and fixed in a linear direction to adjust the distance between the adjustment holder 17 and the holder 16.

This configuration makes it possible to use the device according to the invention in screw caps of various diameter sizes.

More specifically, the adjusting dial 18 and the adjusting holder 17 are configured like nuts and bolts so that the adjusting holder 17 moves in a straight line as the adjusting dial 18 is rotated.

Preferably, a material having a large coefficient of friction or a material having a large elasticity is preferably used at the portion of the holder 16 and the adjustment holder 17 that contacts the screw cap.

Hereinafter will be described in more detail the operation of the present invention configured as described above.

As shown in FIG. 2, the screw cap is positioned between the holder 16 and the adjustment holder 17.

Thereafter, when the upper case 20 is pressed, the lever 11 rotates the pin A 12 about its axis.

As shown in FIG. 3, as the lever 11 is rotated, the holder 16 is linearly fixed to tighten the screw cap together with the adjustment holder 17.

When the screw cap is rotated about the screw cap while the screw cap is fixed by the holder 16 and the adjusting holder 17, the screw cap rotates together.

1 is a perspective view showing an overall exploded view of a screw cap opening and closing apparatus according to the present invention.

Figure 2 is a front view showing a part of the internal structure and the PET bottle and the screw cap before operation of the screw cap opening and closing device according to the present invention.
