The innovation concerns a lid for preserving jars, which allows small amounts of To store food without boiling it have to.

It is known to preserve food in glasses by removing most of the air from them with an air pump. For this purpose, a pump the size of a large bicycle pump is used, which can be screwed to a table in an inclined position and at the end of which a flat needle is attached for insertion between two rubber rings of the glass. After a sufficiently high negative pressure has been reached, which can be read on a pressure gauge on the pump, the needle is removed again. The air pumps used for this process can no longer be placed next to the usual kitchen appliances. When preservation of many glasses ¹ AEIE-ses procedure is also perceived as very raühselig and annoying. In addition, if the de-

distance of the needle, in turn, air penetrates the glass and excludes the hoped-for effect without this disadvantage being recognizable from the outside or being read on the pressure gauge of the pump could be.

The innovation is based on the task of keeping the air pump handy and small and arranging it next to the lid that it temporarily forms a part with the lid and, even if the air pump is improperly removed, no air can enter the Glass can penetrate.

The innovation is seen in the fact that the cover contains an outwardly opening check valve and on which the outer end of the valve has an outwardly widening conical opening for attaching a medical syringe is.

To be sure that the connection point of the lid for the handpiece of the syringe does not leak while the air is being sucked out, in a further embodiment of the Innovation ensured that the medical syringe is well guided between two walls on the top of the lid.

The coin 14 of the medical syringe is inserted in a conical opening 15 of a cap 16, which is open at the bottom, and which is part of the lid is and largely against external influences through walls 17, 18 is protected. Additional walls 19 to 22 serve the relatively thin, disc-shaped central part of the To stiffen the lid and at the same time to offer the fingers a good grip while the air is being sucked out of the jar. In the cap 16, a check valve 23 is again inserted, which has the same shape as the check valve 11 of the Has syringe 5.

The oval disc 24 at the rear end of the syringe tube, which serves as a support surface for the fingers, engages in slots 25, 26 of the walls 3 and 4 and presses the The mouthpiece 14 of the syringe firmly into the conical opening 15 of the cap 16 of the lid 1.

Of course, only one medical syringe is needed for any number of lids.
