Definitions

  • the present invention relates to a handwash­ing paste dispenser for wall installation, capable of dispensing quantities of a particularly thick paste upon each manual operation of a control lever handle hinged to the apparatus.
  • Object of the present invention is therefore that of providing a dispensing apparatus for pasty products having high density such as the hand-washing paste, which can be applied to walls and is enclosed in a housing such as to render the same absolutely similar, as to the outer aspect, to the known dispensers of liquid soap or gel giving the certainty to each user that he comes in contact with a portion of product never touched by other users and thus clean, all that with a simple manual operation of a lever handle and the least waste of product.
  • such an apparatus is designed to be used with containers of the disposable cartridge type, the cover of which has an outer edge acting as a sealing gasket and being removable by tear­ing off from the remaining disk-shaped portion which is adapted to slide along the inner wall of the cartrid­ge under the push of a disk plate that is caused to move downward by a prefixed length upon each operation of the control handle of the apparatus, so as to force the product, without leaving residue, to flow out through an opening previously formed on the cartridge bottom, through corresponding slits provided on the bottom of housing and the control handle itself.
  • the dispensing apparatus comprises structural parts consisting of a back portion adapted to be anchored to a wall, having mounted thereon the dispensing mechanism and hinged the operating handle thereof, of a box adapted to be fastened to said back portion and a cover hingedly mounted to said box for covering the front side of access to the inside mechanisms by means on a snap shutting at the top, and is characterized in that said mechanisms comprise a pair of side links, the lower end of which is connected to said handle and the upper end to the sides of a control bracket being hinged to said back portion and usually kept inclined upward by a compression spring on the front side of a horizontal separating shelf, fixed to said back portion under the pivoting axis of said bracket, on the latter there being also mounted the pivoting axis of a rod pushing plate which is also kept usually inclined upward by a second compression spring between the plate itself and said separating shelf, there being further provided a second plate also hinged at an end to said back portion above said first plate, and being usually kept inclined upward by a third compression spring
  • the links upon a handle operation, accomplishing a limited rotation thereof downward about the hinge pivot on the back portion of the device, the links cause a respective lowering of the control bracket with contemporary com­pression of the associate spring which has loaded for the subsequent return of bracket and handle to the start position.
  • a pivoting point of the rod pushing plate is dragged downward, while said plate is still inclined upward due to the thrust exerted by its associate spring, so as to engage, by the edges of the through hole, the disk-carrying rod by which it is crossed, thus dragging downward the latter by frict­ion, whereas the upper plate is also slightly lowered with a small contemporary compression of its spring.
  • both the plates have a substantially horizontal orientation, thereby leaving the greatest clearance to the rod passing therethrough, which is then free to be shifted at will.
  • the disposable cartridge used as container of the hand-washing paste to be dispensed is provided with a cover the outer edge of which is easily removable such as through an oblique cut, while the remaining portion of equal diameter or only slightly smaller than the inner diameter of the cartridge is slidable, under the push exerted by the disk in its downward strokes, when scraping with its edge the inner wall of cartridge, whereby it is ensured that all the product is used.
  • numeral 1 designates the box which forms the housing of the device and acts as a support for the front cover 2 being hinged to the lower side of box 1, e.g. by means of a pivot 26 passing through mutually aligned bushes 27, 27a integrally formed by molding with cover 2 and box 1 respectively.
  • the cover has a closing tongue 20 suitable to snap fit into a corresponding seat of the upper end of box 1.
  • Through holes (not shown) formed in the wall of the latter allow introduction of tools for lowering the tongue 20 and opening the cover 2.
  • the box 1 is adapted to house at the inside a back portion 9 with all the mechanisms mounted thereon as will be better described in the following.
  • Box 1 and back portion 9, this having holes 29 for the instal­ltion to a wall, are assembled together preferably by means of only two side screws 21 with washer, provided in association with a horizontal shelf 3, which could be called “separating” the purpose of which will be better explained in the following.
  • a handle 4 rotatably mounted about a pair of pivots 18 which are fixed to the device frame by passing through associate holes 18a, 18b, respectively of the box 1 and of back portion 9.
  • the handle 4 is so shaped at its front side, as to aid its grasping by the user.
  • both links 16 are extended upward by passing through slots formed to this purpose in the handle 4 itself, in the box bottom 31, in the bracket 28 and in the separating shelf 3 up to an upper pivoting point 13 where each link is connected to a side of a "control" bracket 10, being hinged in 11 at the sides of back portion 9, slightly above said shelf 3.
  • a conic or cylindrical compression spring 22 On the latter, toward its front side, there is fixed one end of a conic or cylindrical compression spring 22 to the other end of which there is usually resting the front side of bracket 10.
  • a vertical cylindrical rod 19 passes through holes provided in the central zone of shelf 3 and of bracket 10 and its lower end bears a disk plate 5 which is adapted to lower like a plunger within a cartridge 7 (not shown in Fig. 1) so as to push what is contained therein downward by a predetermined stroke for each operation of handle 4, as will be better described in the following, thus causing the product to get out therefrom through an opening formed in the bottom of cartridge 7 before placing the same onto the bracket 28.
  • Corresponding slots or passages 30, 30a, 30b are of course provided in the central zone of bracket 28, of the box bottom 31, and handle 4.
  • a washer 32 for an easier manual holding of the rod 19 for its lifting, with a spacer member 32a thereunder, such as a threaded nut with adjustable positioning, which is suitable to prevent rod 19 and consequently disk 5 from lowering beyond a prefixed limit.
  • a rod pushing plate 14 is mounted on the brack­et 10 as it is hinged to the rear end thereof about a pin 12 which is fixed to bracket 10. Said plate 14 is kept usually inclined, with its free end upward, by a spring 23 capable of exerting its bias between the plate itself and a circular projection 3a integrally formed with the separating shelf 3 and surrounding the hole through which the rod 19 passes through the latter. Also the plate 14 has a hole 34 for the rod 19 passing Atherethrough, the clearance of which is such that, when said plate is normally inclined at rest conditions of the device, the edges of the through hole are in tight engagement with the rod 19, thus "biting" the same at two diametrally opposed points, at different heights spaced by a length corresponding to the plate thickness.
  • an additional plate 15 which could be called of non-return, being hinged at its rear end to the back portion, such as by means of a U-bent tab within a slot formed in a member 36 protrud­ing from the back portion itself.
  • the plate 15 has a through hole 35 co-axial with 34 and the holes provided in the bracket 10 and separating shelf 3 for the passage of a rod 19 and additionally is normally inclined upward like plate 14, as it is fixed at its free end to an end of a third compression spring 24 the other end of which rests, as is better seen in Fig.
  • the clearance between rod 19 and hole 35 will be such as to keep the rod 19 blocked between two opposed edges of the hole when the plate 15 is in the normally inclined rest condition, as shown in the draw­ings.
  • a tooth 15a protru­des by a length sufficient for causing it to come in contact with the underlying plate 14 in case of downward rotation of plate 15 as a consequence of a pressure thereon from the outside by compressing the spring 24.
  • the friction exerted by the downward moving rod 19 against the wall of hole 35 will be such as to reduce the angle of inclination of the plate 15 with contemporary slight compression of the spring 24.
  • the "non-­return" plate 15 will assume a less inclined position thus allowing some clearance between hole 35 and rod 19 for the downward movement of the latter.
  • the downard stroke of the rod 19 and plate 5 for each operation of handle 4 can be controlled in advance through a suitable choice of the lengths and the pivoting points of links 16, of the bracket 10 and the position of the pin 12 on the latter, as well as the bias exerted by the three springs.
  • the lifting will be maximum at the beginning to allow insertion of a new cartridge 7 from which the outer sealing edge will have been already removed while leaving the inner portion 7a of a diameter not less than the disk plate 5, whereas subsequently the rod will be positioned so as to bring the disk into coaxial correspondence with said cover 7a, which has been planned to move downward under the successive thrusts of the disk, still remaining in contact with the inner wall of the cartridge 7, of course upon having formed an opening on the bottom thereof.
  • the apparatus according to the invention is particularly solid and of simple and efficient operation, adequate to the characteristics of the particular product to be dispensed, as it does not comprise parts that may become obstructed or damaged owing to the high density of the product itself.
