Abstract

Reaction vessel opener, by characterized in that it comprises a rod (3) with a gap (4), in a cover (5) can engage such that he in the essentially fitting encloses, where the gap (4) is formed so that the top of the lid (5) adjacent to the long side (11) of the gap (4) and an overhanging one Edge (7) of the cover (5) in the short side (12) of the gap (4) engages and that the rod (3) to a tripod (1, 2) attached is, so to open a reaction vessel only a hand is needed.

Description

The The invention relates to a reaction vessel opener.

in the Laboratory operation, reaction vessels are used, which are closed with lids. Often these lids are over one Tab connected to the reaction vessel, to open it the reaction vessel is not fall off.

To In the prior art, these reaction vessels are opened by hand by They are taken in one hand and the lid with the thumb behind pressed up becomes. Are larger quantities to process these reaction vessels, becomes common a leather puppy used to protect the thumb. With this handling are However, disadvantages associated with laboratory operation. If no Tom Thumb is used, so the thumb is so much stressed that after a short time Time pain sensations and also injuries occur. Becomes a Tom Thumb used, so this is very impractical, as he has other laboratory work disturbs and also the sensitivity affected by other manipulations, for the you feel more needed such as when pipetting liquids. Either the Tom Thumb constantly put on and taken off or the impairments in the other Laboratory work must be accepted.

The US 4,683,782 as well as the US 4,858,502 disclose reaction vessel openers which are suitable for opening reaction vessels which are located in a solid device. The DE 31 41 780 A1 shows a completely automatic device for removing rubber plugs from container tubes for analyzers.

It is therefore the object of the invention to provide a device with the reaction vessels without the above disadvantages are opened can be.

These Task is characterized by a reaction vessel opener with the characteristics of Patent claim 1 solved.

With this reaction vessel opener is it is now possible especially big numbers of reaction vessels for the Thumb-friendly way and without disturbing interruption of the lab work to open.

advantageous Further developments of the reaction vessel opener are in the subclaims specified.

The Drawings show a representation of a preferred embodiment of the reaction vessel opener.

It shows:

1 : The side layer of the reaction opener.

2a) : inen Reaction vessel opener with a closed reaction vessel.

2 B) A reaction vessel opener with an open reaction vessel.

3 : A top view of the gap to be used for opening from below.

4 : A side view of the pole 3 with the gap 4 in the scale 1: 1.

1 shows a reaction vessel opener comprising a tripod with a bottom 1 and a pole 2 at the bar itself 3 is, wel Ches is provided for the opening of the reaction vessel. At the end of the pole 3 there is a gap 4 in the lid 5 of the reaction vessel 6 with its edge 7 intervenes. The width 8th of the gap 4 is sized to the edge 7 of the lid 5 essentially fit in the gap 4 can intervene. The lid 5 is over a tab 9 connected to the reaction vessel. Reference numeral A denotes one through the center of the lid 5 extending perpendicular to the ground. The angle α ₁ denotes the angle that the surface of the lid 5 encloses with the vertical A upwards. The angle α ₂ denotes the angle passing through the bars 2 and 3 is included. In the 1 is α ₁ = 30 ° and α ₂ = 120 °. The angle α ₃ denotes the angle passing through the lower side 10 of the rod 3 and the long side 11 of the gap 4 is included.

α ₃ is 150 ° in this figure.

In 2 For the same device components, the same reference numerals as in FIG 1 assigned.

3 shows a plan view of the gap to be used for the opening 4 from underneath. reference numeral 11 is the long side of the gap 4 and reference numerals 12 the short side of the gap 4 , The edge 13 the short side 12 of the gap 4 is formed in this illustration essentially as a circle.

In 4 For the same device components, the same reference numerals as in FIG 1 assigned.

In a preferred embodiment, the angle α _{3 is} about 150 °. The span of the angle α ₃ can continue to be 120 ° to 170 °. There are also angles α _3, for example, 90 ° conceivable, in any case, the angle α _{3 is} a good intervention of the reaction vessel opener in the lid 5 enable.

The gap 4 has a width 8th that is sized to fit the lid 5 essentially fit in the gap 4 can intervene. The width may be, for example, 2 or 2.5 mm, but is basically based on the dimensions of the lid 5 which is to be opened.

Preferably, the length should be the long side 11 be so big that the lid 5 essentially at least halfway into the gap 4 can be introduced, since the leverage forces work well in this case. By way of example, the length of the long side may be about 12 mm, but it depends on the size of the lid 5 from. The by the long side 11 trained contact surface with the lid 5 can also contact substantially the entire surface touch.

The short side 12 of the gap 4 reaches under the lid 5 , By pulling down the reaction vessel, the reaction vessel can be opened. Angle α ₃ is preferably chosen so that the reaction vessel is oriented perpendicular to the ground after opening. This is the case when the angle α _{3 is} about 120 ° to 170 ° or particularly preferably substantially 150 °.

The gap 4 is preferably dimensioned so that the lid can be inserted substantially pass-fit.

According to 3 is the one with the lid 5 coming in contact edge 13 the short side 12 of the gap 4 rounded so that it has substantially the radius of curvature of the upper side of the reaction vessel or the lower edge of the lid, which encloses the reaction vessel. This has the advantage that the reaction vessel is optimally positioned.

The reaction vessel opener is as a rod 3 with tripod 12 formed in one piece or at least two parts. This arrangement with a tripod has the advantage that only one hand is needed to open the reaction vessel. For an angle α ₁ = 30 °, the angle α _{2 is} preferably 120 °. The combination of the angular dimensions α ₁ and α ₂ should be such that the opened reaction vessel after opening is oriented substantially perpendicular to the ground, since then the risk is lowest that the filling material runs out of the reaction vessel.

With the reaction vessel opener is it now possible Reaction vessels, in particular in big Quantity, fast and without affecting the Thumb and without unnecessary Open the remaining laboratory work.
