Beiersdorf & Co., A.G., Hamburg, Germany Filed Sept. 14, 196i), Ser. No. 55,910 Claims priority, application Germany Sept. 21, 1959 5 Ciaims. (Cl. Z22-L81) The object of this invention is a suspendable tube, the interior of which is intended for use with paste or salvelike substance.
It has been proved useful to keep tubes intended for the care and protection of the skin, and for similar purposes as closely as possible to the place of their use. It is therefore advantageous to use tubes that can be stored in a suspended manner.
There are already known tubes whose lower bent part-s are provided with suspension means, thus enabling the tubes to be hung on a hook or the like. Special means for suspension have to be provided, i.e., a hook, to suspend the tubes in this determined manner.
The present invention dispenses with this disadvantage and enables the user to suspend the tubes at any given place without the need of other means and without darnaging the place of suspension. According to the invention, this is achieved by providing the closure of the tube with a suction device and with means for suspending such closure at the opposite end of the outlet opening.
There are also already known tubes provided with suction devices, intended to hold in combination with its closure the whole tube or its detached opening respectively. Thus the tubes can be stored either in an upward position with their `closed outlet openings directed downwardly, or in a suspended manner, with their closed outlet openings directed upwardly. No means have heretofore been provided to suspend tubes in an open condition with outlet opening downward, by means of a suction device.
According to the present invention, a detached tube closure is provided with a suction device and can be pressed against a smooth surface, thu-s keeping the closure attached due to the -suction effect of the suction device, and the tube can be suspended with its opposite end on the tube closure, thus disposing the tube in a hanging position with its opening extremity downward.
In a preferred embodiment of the invention the inner wall of the tube case is provided at the end opposite to its outlet opening with a looplike perforation thus providing for the engagement of a hook provided at the tube closure. This perforation can be located at the closing -strip of the tube case, for instance in a tube groove or else along the welding line of the tube wall. It is advisable to provide the perforation with a rivet, to be used as an eye -for the reception of a hook secured to the tube closure.
Various possibilities of a design of the tube closure exist. The tube capsule can be provided interiorly with an elastic, unneLshaped, increasing edge attachment forming at its inner side a suction cup and provided at its outer side with a suspension hook. It is likewise possible to place a suction device in inverted position over the tube capsule consisting of an elastic synthetic material bulging inwardly over the capsule and being outwardly likewise provided with a suspension hook. In al-l instances the suction device, rather the rim, has to be proportionally adjusted to the tube shoulder so that the rim wiil be rmly connected with the tube shoulder when the tube is closed and thus protect it against damage.
3,078,017 retreated Feb. 1s, Vnass Y 2 Y The tube according to the invention has the advantage that the tube, being lled for example with a protective skin salve, can be "suspended inthe immediate vicinity of a water faucet. When utilizing synthetic tubes,the tube contents can be easily extracted from the tube while the latter is in a suspended position, without being taken off the hook or without the necessity of closing its opening outlet after usage.
A preferred embodiment of the invention is illustrated in the accompanying drawing, wherein FIG. 1 is a side view, in elevation, of the device;
FIG. 2 is a front elevation of the device;
FIG- 3 is a View of another embodiment;
FiG. 4 is an enlarged section of the device.
The device accord-ing to the invention will now be more fully described with reference to the accompanying drawing, but it should be understood that this is given by way of illustration and not of limitation and that many changes may be made in the details without departing from the spirit of the invention.
FIG. 1 shows a tube l with a tube -groove (notch) 2, which in the case of synthetic tubes can be replaced by a longitudinal wel-d of the tube walls and perforated at 3. The tube closure consists of a cap 5 made of synthetic material provided with a soft cap 6 of resilient synthetic material. Cap 6 has a funnel-like elongation 7 abutting against tube shoulder 9. At its opposite end the cap is provided with a hook-like extension 8, adapted to -ft into perforation 3.
FIG. 2 is a side View of the -tube as shown in FIG. 1 with the tube cap detached and serving as a suspension means for tube 1.
FlG. 3 shows the perforation 3 by using a rivet 4 below the seam weld. This is especially of advantage when using synthetic tubes in order not to overtake or reinforce the welding seam.
FIG. 4 is a cross-section of a tube weld end with a hollow-type rivet.
We claim as our invention:
l. A suspendable tube for salve-like substances, comprising, in combination, a cylindrical container body, having an open neck portion and a closed flat end seam having an aperture therethrough, a detachable closure for said open neck portion, said closure including a resilient conical cap adapted to be secured to a ilat surface by suction, and a suspension hook element integral with said closure, adapted to be received in said aperture for suspending the tube.
2. The tube according to claim l, further provided with a hollow rivet extending Ithrough said aperture toV reinforce the latter.
3. A suspendable tube for -salve-like substances, comprising, in combination, a cylindrical container body, having an open neck portion and a closed at end seam, a reinforced section formed with an aperture therethrough, adjacent said flat end seam, a detachable closure for said open neck portion, said closure including a resilient conical cap adapted to be secured to a flat surface by suction, and a suspension hook element integral with said closure, adapted to be received in said aperture for suspending the tube.
4. The tube according to claim l, wherein said neck portion is formed with a truste-conical shoulder, extending from said neck portion to said cylindrical container body, said resilient conical cap having the configuration of said frusto-conical portion.
5. A suspendable tube for salve-like substances, comprising, in combination, a cylindrical container body having an open neck portion and a closed fiat end seam, said seam having an aperture therethrough, said neck portion including a non-resilient mouth part, a detachable non-resilient closure adapted to t over said mouth part, a resilient frusto-conical cap integral with said closure, said cap being adapted to be held by suction against a dat surface when said closure is detached from said neck portion, and a hook elemen.` extending from said closure, adapted to be receivedin said aperture for suspending said tube.
