Abstract
Abstract A device for extracting a liquid or pasty substance from a tube (19) comprises a key (10) having a hollow shaft (11) which is provided with a widening longitudinal slot (13) open at one end, and a handle (12). The end of the tube (19) is gripped by insertion into the longitudinal slot (13) from the open end.
The hollow shaft (11) of the key (10) gripping the end of the tube is pushed from one side into an elongated horizontal recess (8) which is formed by a depression (9) in a baseplate (2) of a holder (1) and by a clamping plate (3) of elastic material projecting over said depression. On the bottom side it is bounded by a shoulder (5) which together with a curved portion (7) of the clamping plate (3) forms a clamp slot (9) through which the tube (19) is passed. Through the turning of the key (10) the tube (19) is pulled through the slot (91 into the recess (8) and rolled up. Thereby, or when pressure is applied to the tube (14), substance is extracted from an outlet slot (16) in a closure cap (15) made of rubber.

Description
2 ~ 5 2 Device for extracti~g a substance from a tube 5 The invention relates to a device for extracting a substance from a tube, according to the preamble of claim 1.
Devices of this kind are known which merely comprise a key gripping the end of the tube. Turning the key while at the same -~
time firmly holding the tube enables the latter to be wound up 10 on the key and its contents to be squeezed out. A solid or pasty substance contained in a conventional aluminum tube can ~`
be satisfactorily extracted with such devices, although the fact that two hands are needed is often a nuisance.
The situation is different wlth tubes of plastic material, 15 which are being increasingly widely used and which tend to unwind and resume their original shape as soon as the force applied is relaxed, so that the contents of the tube are usually distributed over the length of the latter. The extraction of a substance from a tube which has already been 20 largely emptied is thus rather awkward with such a device, ~because each time the tube must be almost completely wound up from its original shape.
The invention seeks to provide a remedy in this respect. The invention, as characterized in the claims, provides a device 25 for extracting a substance from a tube, with which the unwinding of a partly emptied tube from the key is reliably prevented.
Other advantages achieved through the invention are to be seen in the fact that the substance can be extracted from the tube 30 with one hand, and that in particular tubes made of plastic ~6~5%
material, which are problematic in this respect, can be emptied more completely than hitherto, as is desirable with a view to avoiding unnecessary waste and achieving better utilization and therefore economization of resources.
5 The device according to the invention forms at the same time a means of storing the tube, on which the latter can easily be suspended in an accessible manner.
The invention will be explained more fully below with the aid of drawings, which illustrate merely an embodiment of the 10 invention and in which:
Figure 1 is a side view of a device according to the invention, with a tube clamped in place;
F~gure 2 is a front view of the holder of the device shown in Figure 1;
5 Figure 3 is a plan view of the key of the device shown in Figure 1, and Figure 4 is a section through the mouth of the tube, with a closure cap of the device shown in Figure 1.
The device comprises a holder 1 having a baseplate 2, for 20 example of metal or plastic materiall and a clamping plate 3 of elastic material, for example stainless steel, fastened on said baseplate. The baseplate 2 is provided with a depression 9 which extends o~er its entire width and has a uniform, substantially semicircular cross section, and which is bounded 25 at its bottom side by a shoulder 5 merging into a return 6 lying beneath it. The baseplate 2 is fastened to a wall, for example by adhesion or doweling.
The clamping plate 3 is fastened to the baseplate 2 above the depression 9 and extends downwards, with the same width as the 30 baseplate, to a point slightly beyond the shoulder 5. ~pposite the shoulder 5 it has a curved portion 7, whose convex side , .
2 ~ 5 2 ~aces said shoulder. It covers the depression 9, in conjunction with which it forms an elongated horizontal recess 8, which is open at both ends and at its bottom side has a clamp slot 9 formed between the shoulder 5 and the curved portion 7.
5 The recess 8 serves to receive a key 10, or more precisely a hollow shaft 11, carrying a handle 12, of said key. The hollow shaft has a longitudinal slot 13, which is open at the end opposite the handle 12 and widens in the direction of this opening.
10 For the purpose of clamping a tube 1~ containing a liquid or pasty substance, for example toothpaste, the usually thickened end of said tube is pushed from the open end into the longitudinal slot 13, this being facilitated by the widening of the latter, and is clamped fast there. The key 10 is then 15 pushed from the left, the right or the bottom into the recess 8, so that the end part of the tube 14 is inser~ed into the clamp slot 9 and the latter is slightly widened, with slight elastic deformation of the clamping plate 3, and thus a certain pressure is exerted on the tube 14 by the shoulder 5 and the 20 curved portion 7.
The original rotatable closure is replaced by a closure cap 15 of elastic material, preferably rubber or plastic, pushed onto the screwthread ~o close the tube 14. In the forward direction said cap tapers off semispherically to conically and at its 25 front end has an outlet slot 16.
If the key 10 is then turned by means of the handle 12 projecting sideways out of the recess 8, which can easily be done with one hand, so that the end part of the tube 14 guided through the clamp slot 9 into the recess 8 is wound onto the 30 hollow shaft 11, a portion of the part of the tube 14 lying outside the recess 8 will be pulled through the clamp slot 9 and clamped between the shoulder 5 and the curved portion 7, so that said portion, on passing into the recess 8, is practically completely emptied. In the interior of the part of the tube 14 , ., . ~ :
4 ~
lying outside the recess 8 a overpressure is produced, which has the effect that the outlet slot 16 in the closure cap 15 will open and some of the contents of the tube will be discharged. When the pull on the tube 14 and thus also the 5 overpressure end, the closure cap 15 is automatically closed again.
If the part of the tube 1~ lying outside the recess 8 is tightly filled, hand pressure will also suffice to produce overpressure inside the tube and to discharge the substance.
10 After a few extractions in this way it will be necessary to wind up the tube 14 again, so that the part lying outside the recess 8 will once again be adequately filled.
When the handle 12 is released, the part of the tube 14 wound onto the hollow shaft 11 can scarcely unwind, because the 15 recess 8 does not offer sufficient room to allow this. Its dimensions are such that it provides sufficient space for the key 10 and a tube almost completely wound onto the latter, but does not permit the unwinding of the tube.
On the turning of the key 10 there is therefore at most a very 20 slight idle movement.
The device described permits the use of tubes 14 of different widths. The tubes can be almost completely emptied.
The device is not only convenient to install and operate, but is also sim~le and inexpensive to manufacture.
