. Packaging for long, cylindrical glassware.

I The invention relates to packaging for long, cylindrical

I drical glass utensils, especially for thermometers, areome-

I fabric tube that is closed on one side with a plug,

I to which the glass device rests on a foam insert.

ί For the packaging of thermometers and areometers,

f going cylindrical sliding sleeves made of sheet metal, cardboard or the like,

i used. As far as these devices are produced in large series

J, there are only relatively short length

tolerances, so that they can be

l location »z. B. equalized in the form of a foam plug

Can be used to ensure a tight fit in the glass appliance to lend the packaging.

In the case of larger glass devices, such as thermometers or areometers, which are manufactured in smaller series, there are larger dimensional tolerances ,, Avis for this reason has already been proposed for such devices, transparent extruded Use plastic pipes that are specified by the device manufacturer Cut to length and sealed on one side with a stopper. At the other end is the plastic pipe closed with a sliding sleeve as usual. In addition to the manufacturing advantages, this packaging has the advantage that the packaged device can be seen from the outside, with the result that storage is simplified and the visual appearance Presentation in sales is improved. However, this packaging also has the disadvantage that it has length tolerances only compensates within limits, since even if a foam plug is used, it is often not from the outside you can see whether the device is still resilient or practically absolutely tight in the packaging. This is because the glass device, especially if it has very narrow cylindrical sections, penetrates the foam plug, without being able to see from the outside how far the tip of the glass device has penetrated into the foam plug is. If the sliding sleeve is pushed on too tightly or pushed open during storage or transport, this leads to long devices inevitably break.

The invention is based on the object of compensating for even greater length tolerances and of the device in an axial direction In the direction of resilience, but in the radial direction to create packaging that holds it out.

According to the invention, this object is achieved in a packaging of the type mentioned at the outset in that the one-sided plastic tube closed by a stopper with a hissing connection of a foam insert on his the other end is closed with a stopper to which a

is arranged in the tube protruding cylindrical spring part made of plastic.

The invention thus moves away from the previously known sliding sleeves and instead uses simple pipe sections each with attached plastic stopper · The axial suspension and radial guidance is provided by the cylindrical Reached the spring part at the one stopper.

This spring part can have a hole for guiding the glass appliance on its free end face. In this hole can For example, the blowing tip of the glass device can be introduced so that the glass device is fixed radially. Also at Overlengths cannot break because both stoppers are tight against the edge of the opening and no longer - as with the sliding sleeves - can be moved.

In a preferred embodiment of the invention, the spring part is a bellows made of an expediently likewise transparent plastic. The bellows pushes together more or less depending on the length tolerance. The scope the compression can be seen from the outside, so that there is no risk of the glass device in the packaging is tightly braced, so to speak.

In the drawing, a preferred embodiment is shown Invention shown in longitudinal section. An areometer 1 with a density scale 2 is an example of a glass device and a temperature comparison scale 3 is shown. As known, the areometer has a comparatively large diameter in the area of the temperature scale, in the area of the density scale In contrast, it has a much smaller diameter.

The glass device 1 sits in a package designated as a whole with 4, which consists of a cylindrical, cut to length.

ten tube 5 made of transparent plastic and two plugs 6, 7 closing the ends. Between the Stopper 6 and part 2 of glass device 1 has a foam insert in the form of a cylindrical stopper 8. The plug 6 is hollow for this purpose, so that the foam plug 8 is pressed into it can be. The stopper 7 at the opposite end of the tube 5, on the other hand, has an axially resilient pedestal 9 also made of plastic. In the exemplary embodiment shown, this spring part is designed as a bellows 10 which has an opening 11 for receiving the one pointed one Has the end of the glass device 1 and this thus leads in the radial direction. Of course, the spring part 9 can also be a have other three-dimensional shape, the only condition being that this part has both sufficient resilience as also has the longest possible spring travel.
