DE102006039405A1 - Screw clamp for opening/closing screw cap, has upper and lower pressure plates, where pressure is exerted on cap with spindle coupled with spring, and cap is detached by rotation of upper pressure plate, if pressure is high - Google Patents

Abstract

The clamp (1) has an upper pressure plate (6) and a lower pressure plate (2), where pressure is exerted on a cap with a spindle coupled with a compression spring (5). The cap is detached by the rotation of the upper pressure plate, if the pressure is high. A lining of arbitrary anti-skid materials such as rubber and plastic, is provided on the upper and lower pressure plates, and a centering aid is provided with a metal ring (8).

Description

The The invention relates to a device according to the preamble of claim 1.

It is known to open it from screw jars There are various pliers. They damage you but the tin lid, which can then close bad again.

These Press pliers with her teeth the sheet metal lid against the glass thread. This makes opening even more difficult. Of the Lid is damaged here, what the resealing difficult. When opening are both hands of need. Although the pliers have a leverage effect at the top, the glass does you have to Hold with the other hand.

Of the screw-top opener The task has a glass with screw cap and with ease to open a hand.

By a screw clamp with an upper and lower pressure plate. On the lid is subjected to pressure. If it is high enough, the lid can be turned by turning the top Pressure plate solved become.

Of the Lid can be opened or closed with just one hand. It does not take much effort, which is just for older or handicapped people is beneficial. The tin lid will not damaged, he let reclose comfortably. The screw cap opener let yourself easy to use.

These Device would let also automate to even more convenient and faster lid open.

each conceivable glass size - be it in diameter and in height - let to open with the device. Even with soda bottles, the system works.

First, take a commercially available screw clamp ( 1 - 1 ) ago. But there are also other basic support possible such. B. multi-arm devices or presses. Also the materials: steel, aluminum, plastic etc.

Here it is described with a screw clamp. On the rigid projection is a metal plate - the lower pressure plate ( 2 - 1 and 2 ) welded.

On the internal thread of the sliding projection was a left-handed nut ( 3 - 1 ) welded. A right-hand thread would also be possible here.

At the Upper end of the thread is an eyelet as a recording of the transverse grip serves.

At the lower end of the thread is a sleeve ( 4 - 1 ) welded. This serves to guide and to hold a compression spring ( 5 - 1 ). Here, the compression spring was welded.

Now, a hole is drilled through the upper pressure plate centric, which is as large as the inner diameter of a ball bearing. With a countersink, the hole is now lowered. Printing plate ( 6 - 1 ), Spacer and ball bearings ( 7 - 1 ) is screwed together with a countersunk screw. The spacer is required in between to avoid distortion. Now fasten the ball bearing and compression spring with a hose clamp.

Then here is a metal ring ( 8th - 1 and 2 ) centrally welded to both printing plates. In these metal rings is finally a correspondingly large rubber ( 9 - 1 and 2 ).

It are also other solutions conceivable, about a step-shaped Rubber - from Outside descending inwards. Other slip resistant materials could be here also find use.

Also the centering could for example about Markings or other adjustment aids take place.

The Pull the upper projection upwards and the screw cap glass on the put lower pressure plate. Put the upper projection down on the lid. Turn the cross handle to the left until a correspondingly high pressure is achieved comes on the lid. The firmer the closure or the higher the vacuum in the glass the higher must the Be pressure on glass and lid.

Now let yourself Loosen the cover by turning the upper pressure plate. Turn spindle back and raise the outreach. Lid is now loose on the glass.

Claims (6)

Device for opening or closing screw caps, characterized in that the device can be constructed arbitrarily. Here in the form of a screw clamp, all other types are possible, such. B. a column, multi-arm versions, etc. to be able to set a glass, for example. Apparatus according to claim 1, characterized in that here the pressure is from above with a spindle paired with a compression spring. There are but also all other techniques that can create pressure from above, below or sideways, such as: B. on leverage, muscle power, screw press, hydraulics, pneumatics, etc. Device according to claim 1 or 2, characterized that the coating on the printing plates with any slip-resistant Materials such as rubber, cork, plastics etc. can be done. Device according to one of the preceding claims characterized in that the centering aid here with a metal ring was equipped. It can also be used with other suitable aids take place such as a stepped pressure plate or with a color mark. Device according to one of the preceding claims in that here the upper pressure plate is rotatably mounted is, it would be also possible, to do the lower pressure plate like this. The rotation itself can be done with all technically-known means, like an extra Handle or be automated. Device according to one of the preceding claims characterized in that jerky or fast-paced and / or Turning - the off known in the art - act on the lid or the container to be included.
