DISPENSING DEVICE Filed Oct. 18. 1961 2 Sheets-Sheet 2 United States Patent 3,181,738 DISPENSING DEVICE Leif Hartvig-Johansen, Elisenbergvein 35A, Oslo 2, Norway Filed Oct. 18, 1961, Ser. No. 145,869 Claims priority, application Norway, Nov. 4, 1960, 137,880; July 5, 1961, 140,798 7 Claims. (Cl. 222-156) This invention relates to dispensing devices of the type which comprises a container for powdered or similar material, which container can be connected with an underlying dispensing device containing a dispensing or feed plunger with an operation arm or the like, whereby suitable portions of the material in the container can be pushed out through a feed aperture.
Dispensing devices are known, wherein for instance, soap powder is charged into a container, the lower part of which is connected to a suitable dispensing device. This dispensing device can for instance be of plunger type and such that each plunger stroke feeds out a certain suitable portion of the soap powder.
The purpose of the invention is to provide such a dispensing device which is very simplified in its construction and use. This is obtained by arranging a dispensing mechanism known per se, forming a partof a housing which is adapted to tightly enclose one end of a substantially parallellepiped machine-filled standard carton or the like, one corner of which is provided with weakening lines or the like, so that the corner may be removed before the carton is mounted in the housing.
In the use of a dispensing device according to the invention it is not necessary to transfer the powder material from the carton to a separate container which is a part of the apparatus, but the carton itself constitutes the container. Thereby the work necessary in transferring the powder to a separate container is eliminated, at the same time as the general inconvenience of dust and so forth is avoided. The carton according to the invention is preferably devised with the one end closure flap made very short. and connected to the side wall of the carton by a folding, wherein a weakening line is contained so that the whole of this flap can be removed as the corner is torn open by aid of the other weakening lines. The material in the carton will thus run down into the dispensing mechanism without being stopped by remaining flaps.
A special housing known per se can be used with advantage for securing the carton to for instance a wall. This housing is then preferably provided with a window for reading the instructions on the standard carton. Further the housing can with advantage be lockable.
The above-mentioned as well as further characterizing features of the invention will appear more clearly from the following detailed description of some embodiments shown in the accompanying drawings in which:
FIG. 1 shows in perspective exploded view the lower part of a standard carton with the associated dispensing mechanism according to one embodiment of the invention;
FIG. 2 shows a somewhat modified version of the embodiment shown in FIG. 1, the modification being seen in cross-section;
FIG. 3 shows a carton according to the invention as seen from the securing end with side flaps swung out so that the form of the end flaps as well as the weakening lines are seen;
FIG. 4 shows the tearing-off corner of a carton according to the invention;
FIG. 5 shows in top plan view the foremost part of the dispensing plunger according to the modification shown in FIG. 2;
FIG. 6 is a perspective view on a smaller scale of a housing wherein the dispensing device is arranged according to the invention; and
FIGS. 7 and 8 respectively show the housing open and ready'to receive a carton and the housing closed.
The arrangement according to FIG. 1 consists of a parallelepiped carton 1 or the like containing for instance soap powder. Dispensing means of a type known per se, having a plunger 3, which moves in a short tray-shaped casing 2, is arranged to be secured to the lower part of the carton 1, the casing 2 tightly surrounding it with the bottom of the carton 1 in contact with the top surface of the plunger 3. Plunger 3 can be moved by a handle 4, whereby the front edge 23 of the plunger pushes the powder which has run down from the carton 1 out through the dispensing aperture 5.
The carton 1 is so devised that a corner thereof can be removed before it is placed in the casing 2. In the example shown, the corner is made with a curved weakening line 7 and transverse lines 8, 8 in the side closure flaps 12, 13 at the bottom. The end closure flap 11 is of usual length, whereas the end closure flap 9 which lies under the tearing-off part-s outside the weakening lines 8, 8' is very short, preferably of the same length as said tearing-off parts. This short flap 9 is connected to the side of the carton with a folding, containing a weakening line 10.
The device of the tearing-off corner for the finished carton is seen in perspective view in FIG. 4. By a pressing for instance of the thumb against the curved part under the line 7, this part may be pressed in and when thereafter torn outwards, the end flap 9 as well as the parts outside the lines 8, 8' will'follow. Thus, the whole corner can be removed Without leaving any parts that might obstruct the path of the powder from the carton 1 to the space in front of the pushing edge 23 of the plunger 3.
When thus the dispensing device by aid of the casing 2 is fastened to the end of the carton 1 after the corner has been removed as described, a working dispensing device is obtained. If the casing 2 is dimensioned .for tight enclosure of the end part of the carton 1 it is not necessary to have special means to secure these two parts together. Such means may of course be embodied in the device if it should'be convenient.
The device according to FIGS. 2 and 5 differs from the one shown in FIG. 1 only by the arrangement of the feed plunger 3' with a transverse member 15 attached to the plunger 3 by the side members 16, so that an aperture 22 is formed, constituting the space down into which the powder from the carton can run. The transverse member 15 will in inactive position of the device cover the opening 5 so that the powder cannot run out. When the handle 4 is pressed in, the plunger 3' will move towards the opening 5, and the amount of powder in the space 22 will be discharged. Where the dispensing device is used, for instance in wash-rooms, toilets and so forth,
it is advisable to put a shield 17 or the like over the dispensing aperture, so that wet hands will not touch the plunger or the dispensing device, which might spoil the functioning of the device, as moisture could result in the forming of lumps etc. in the powder.
The plunger 3' is spring-loaded at the lower surface 2 of the housing by a pressure spring 6, acting on the bent branch 4' of the operation handle 4. By every stroke of the plunger 3' towards the left in FIG. 2 a portion of the powder 14 corresponding to the space 22 of the plunger 3 is discharged. 7
For use where vibration is encountered, for instance in railway wagons, the device shown in FIGS. 2 and 5 is preferable, since the vibration will not cause the powder to spill through the opening 5 when the device is inoperative. For home use or the like the device according to FIG. 1 is very serviceable. The powder under ordinary circumstances will not run out through dispensery aperture 5, since the resistance to flow of the powder exceeds the pressure exerted by the powder in a full carton. Therefore, it is understood that it is necessary to push the material out with the plunger.
The described dispensing device of FIG. 1, for example, can with advantage be arranged in connection with a surrounding housing 18 having an aperture 5' in registry with opening 5 of the casing for pernritting the passage of material therethrough under the action of plunger 3. The arrangement preferably includes a plate 26 fastened to the wall, the housing 18 having trunnions 19 rotatably fastened to plate 26 such that the housing is pivotally movable with respect to the plate 26 between a closed and an open position. Locking means 20 is provided to lock the housing in the closed position. The housing 18 preferably has a window 21, through which instructions on the carton can be read.
In FIG. 7, the housing is shown in perspective view in open position for the mounting of a carton 1. The corner 25 of the carton is first removed and the carton is held with the opening up and then pushed into place in the downturned housing 18. In the embodiment shown in FIG. 7, the despensing device is secured in the housing 18. The carton 1 is inserted along the path of arrow P into engagement with the plunger 3 and into the edge of the tray-shaped casing 2 whereupon the housing 18 is pivoted around the axis of the trunnions 19 in the direction indicated by the arrow P FIG. 8 shows a longitudinal central section through the device according to FIG. 7 with the housing 18 in a turnedup or closed position. Therein can be seen plate 26 which by screw-holes 27 and screws 28 is secured for instance to a wall 29. The upper part of the plate 26 is provided with a protrusion 31 provided with an aperture 32, adapted for cooperating with a cross bar 33 which is supported in housing 18 and, which can be pivoted by a key 34. The housing 18 will in a locked position be secured to the plate 26 so that the carton 1 cannot be removed by unauthorized persons.-
In FIGS. 1-4, the device is shown based on one corner being removed by the aid of weakening lines for provision of a necessary feed out aperture for the carton 1. In
1G. 3 there are shown weakening lines 24 which may be arranged in the middle part of the carton, if desired. Usually the end fiap does not extend as far as weakening lines 24 and to break through the carton it will be necessary only to break through the side flaps 12, 13.
For dispensing devices according to the invention there may further, according to the invention, be arranged means by the aid of which one can see when a soap powder carton is nearly empty. For this purpose the housing, in which the carton is placed, may be provided with a vertical slit 40 which is relatively narrow, and each powder carton is provided with a window 41 in registry with the slitlike opening. The window 41 in the carton is usually somewhat broader than the slit 40 in the housing. This slit must be so narrow that one cannot cut the transparent material that covers the window of the carton with a fingernail and thus tear it, so that the soap powder runs out.
Experience has proved that the slit-like aperture which constitutes the window in the housing should not be more than 5 mm. broad, and preferably not more than 3 mm. broad. With regard to the window in the carton there is no limit.
The apparatus may be modified so that the housing itself directly serves as a container for the soap powder. In this case the slit in the wall of the housing must of course be covered by a transparent material.
With such a device, one is always aware of when the soap powder in the container is getting low, so that one in time will be aware that the spent carton must be replaced by a new one. The height of the slit or the win- A dow for controlling the level of the soap powder can with advantage cover a fourth or a third of the height of the carton, measured from the bottom.
It will be understood that the invention is not limited to the embodiments shown in the drawings and here described, but can be modified in several ways within the scope of the invention.
