Jar opener

This innovation simplifies and facilitates the opening of jars with threaded closures.

For durability reasons, the glass lid is pressed tightly by negative pressure and can therefore only be opened with difficulty. It is therefore necessary to lift the lid sideways so that the interior of the glass can be ventilated.

In the known devices according to DE 83 22 598 U and US 4 520 696 A, the actuating force acting obliquely upwards is transmitted to the lower edge of the lid or bottle closure edge by means of a pressure part through a lever effect.

According to the patent documents cited, the required support is provided by glass shoulders under the edge of the lid, which, however, not all types of glass have.

Another known device is supported on the upper side edge of the lid. Here the lid edge lifting part is located between the support part and the handle.

A disadvantage of the jar openers mentioned is the positioning of the pressing part from below to the lower edge of the lid, next to which a ring bridge is sometimes arranged.

Another disadvantage is that the operating handle is located to the side of the glass and the direction of the operating force is diagonally upwards, meaning that the entire glass holding force must be exerted by one hand when opening.

In this innovation, the support part is arranged between the handle and the lid = lifting part.

The flat lid lifting part, which is perpendicular to the connecting rod, has a curve on the underside, towards the connecting rod, which is pushed under a point on the lower edge of the lid during use and encloses it. If a pressure force is now exerted on the handle while the support part is resting on the lid, the lid is lifted locally.

The elongated support part is perpendicular to the connecting rod, which it keeps at the desired distance during use. It presses the lid down, but its elasticity allows the lid area between the support part and the lifting part to be lifted sufficiently even with a relatively small actuating force on the handle.

In comparison with the researched jar openers, the jar opener according to the innovation has significant advantages.

Handling a device from above is considered to be more advantageous than handling it from the side or from below. The actuating force is directed downwards. This significantly reduces the total force with which the glass must be held when opening. In addition, a compressive force can generally be applied more easily than a tensile force.

It is also very easy to use: after placing the support part on the lid, the opener is moved until the lifting part is on the edge of the lid, and this is then slightly raised by briefly pressing the handle. If the lid is also still very tightly screwed on, it can be easily unscrewed with the opener after loosening the lid thread at certain points around the circumference of the lid.

This method can also be used to open jars with flat threads. They can still be found occasionally on the markets.

A simple embodiment is shown in Fig. 1. The connecting rod -10- consists of a threaded part -5- and a handle part -9-. The lid lifting part -3-, which has a rounded part -4- at the bottom, and the angled support part -6- are attached to the threaded part -5- by means of the nuts -1-, -2-, -7-, -8-. The rounded part -4-, which is open at the top, serves to hold the lower edge of the lid.

Two approximate dimensions: the length of -6- approx. 10cm, the distance lid = lifting part - support part approx. 3cm.

An additional clamping device for jars, which can be fixed to a table, enables people who only have one hand, or can only use one, to open jars. It can be very simple in design. The new jar opener is advantageous for this, as it is used above a jar and therefore leaves the space required for the clamping device free at the side. This corresponds to the trend of the times to enable the use of various devices by means of appropriate adaptations.

Claims (4)

1. Jar opener, characterized in that one end of a connecting rod is designed as a handle, and at the opposite end, transversely to the connecting rod, a flat lid lifting part with a lower, inwardly directed curve is arranged, and that, spaced from the lid lifting part, a support part, fixedly or detachably, is attached to the connecting rod. 2. Jar opener according to claim 1, characterized in that the support part is designed as a flat rectangle, in particular with an angled lower part, whereby a larger support surface is formed on the lid, or on its edge, and that the rectangle is arranged symmetrically and perpendicular to the connecting rod. 3. Jar opener according to claims 1 and 2, characterized in that the support part is designed in the form of an obtuse angle, the two legs of which rest on opposite edges of the lid when the jar opener is in use. 4. Jar opener according to claims 1 and 2, characterized in that the lower edge of the support part is shaped so that it is spaced from the central region of the lid surface in the working position of the jar opener.
