Description

Telescopic closure for can and canister-like Container

The invention relates to a telescopic closure for can and canister-like containers, in which the part of the closure protruding beyond the top of the container is kept particularly low in order to ensure that the containers can be stacked properly.

Closures are known in which the pouring tube is integrally connected to the lower part of the closure which fixes the closure in the container and in which the pouring tube can be turned into the interior of the container like a bellows. These closures also enable the containers to be staggered, but have the disadvantage that very thin-walled parts must be present in order to enable the closures to be turned inside. For understandable reasons, these thin-walled parts are particularly at risk in the case of aggressive filling goods and often lead to stress corrosion cracking and thus to leaks. There are also known Teleskonverschlüsse in which a threaded Nete piece with the container a \: is connected to f different ^Ti 7eise having a screw cap which can be screwed onto the annannten container neck ur.n which is called a telescopic tube is located in the interior of the threaded stub, then after unscrewing the jug it is

can be pulled to allow pouring. These closures have the disadvantage that the ^ e '-' indestutzen a ² ? have a certain height so that the screw can be screwed on, which has a negative effect on the ability of the container to stand.

The object of the present invention is a telescopic lock for can and canister-like containers, which are inserted in the State of a particularly low construction height of the, part, which is about protrudes the topsoil.

According to the invention, this object is achieved by an on the container undetachable to be attached, provided with internal thread closure lower part and one with a corresponding external thread provided telescopic tube.

This has the advantage of a particularly good star> el ~ availability xind the possibility of the top floors of the containers not to have to pull particularly deep, whereby a reminder of work and .material is achieved.

The '"• thread of the telescopic tube can extend over the whole of the g extend or it can only be a thread on the top and optionally also be attached to the lower end.

A scintillating lid is attached to the telescope tube, expediently by means of a hinge-like connecting band. This Schnanndec ¹ '"! Can be welded in places with the closed lower part, whereby the originality of the container is brought about and at the same time the rchna is secured against unintentional opening during the transport or run. The dissipation takes place of course in such a way that the first in-use near this "'- ⁷ creates ^T - ^T eissunn ·

perforated or torn by hand. To this end, special bracing sheets are attached ^{to the Schnanndec v el.}

To easily slide the telescopic tube into and out of the lower part of the lock To be able to exercise, there are two toggle-like at the upper end Continuations attached, appropriately carved in one piece. These continuations are rigid in a tangential seal and elastically resilient in the axial direction. the Rigidity in the tangential seal ensures good grip when screwing and unscrewing, while the elastic ! Tachgiebigke.it in the axial direction causes bein. Sticks of containers one on top of the other, this continuation is pressed downwards v / earth.

The drawing shows an embodiment of the invention depicted schercatically.

Show it:

FIG. 3 shows a section in the direction B-B of FIG. 2.

^As can be seen in the figures, a lower closure part 1 is provided, which can be permanently inserted into a container. The = · can e.g. P-. By snapping into the unbent edge of the opening, you can reach ' ^T <? rden.

The closure part 1 has an internal thread 2 into which the corresponding external thread 3 of the T ^ les ^l -orirohr ^ s 4 can be screwed. The telescopic tube has the usual channel with the ventilation opening 5.

An upper end of the snap cover 7 is fixed by means of hinge-like acting ^Getting Connected band. 6 The snap cover 7 has welding flaps 8 which can be welded to the upper edge of the lower part 1 of the closure in places. These welding rags can easily be removed by hand before first use.

Above the internal thread 2 of the closure part 1 and the external thread 3 of the telescopic tube 4, there is expediently a sealing cone inserted. The snap-on cover 7 can be fastened in one piece to the telescopic tube via the connecting band 6.

To facilitate screwing in and unscrewing, the toggle-like continuations are located at the upper end of the telescopic tube 9, which are rigid in the tangential direction and in the axial direction are designed to be elastically resilient. When a further container is put on, these continuations 9 are pressed downwards and do not hinder stacking.

When using the telescopic tube is unscrewed, by means of the handle 10 upwards <"retract <" ren up to the stop 11. It is advantageous to attach an external thread to the lower end of the telescopic tube so that the pulled out Telescopic tube can also be safely locked in this state.
