Abstract
Description
- The present invention deals with an apparatus for dispensing determined quantities of pasty products, in particular in the form of gel, especially usable as handwashing paste.
- Devices for dispensing liquid soap are known, which are installed in lavatories of public premises and communities of whichever type. Among these latter there are cases in which it is convenient to supply special products for washing the hands, and particularly in mechanic workshops and certain industrial plants where operations are made which cause the personnel to touch dyestuffs, oils, greases, powders, etc. resulting in a heavy soiling, it is preferable to use the so-called "hand-washing pastes". However these pastes, often available in the form of gel, cannot be dispensed without problems by the usual dispensers of liquid soap due to their higher density. Difficulties in determining the single quantities are met, since the dispensed batches should be greater and the density itself of the product prohibits to have a constant supply. There is also the need of frequent maintenance interventions to ensure a continuous flow of the product which may stop easily, still due to its high density.
- It is an object of the invention to provide a dispensing apparatus particularly adapted to supply determined quantities, possibly adjustable, of products having density equal to or higher than a usual liquid soap, in particular being in the form of gel.
- Another object of the invention is that of providing an apparatus of the above-mentioned type, having a satisfactory autonomy of operation, as it can be used with containers of large capacity, both of the disposable cartridge-type, and such as to be refilled each time, and being solid and of simple operation so as to require only a minimum servicing, if any.
- These and further objects of the present invention will be obtained with an apparatus comprising a support body for partially housing a container of a pasty product like a gel, to be anchored to a wall with its rear side, having pivotedly mounted at the front side thereof a handle to be gripped for being pushed inwardly of the apparatus, thus pressing with a shaped profile integral thereto against a cylindrical wall of a metering valve for unidirectional supply housed within said body and coupled to the downwardly directed outlet opening of said container, there being also provided means for fastening the container to the apparatus body which are unlockable from the outside by a properly designed key, adapted to rotate a rod-shaped member which is housed within said body and provided with means engaging the latter and said container, the return to the locking position being ensured by spring means integrally formed with said rod-shaped member.
- According to a particular feature of the invention the operating handle, which is by the way easily graspable by the users, must be pushed against the supporting wall, thus being possible to exert a stronger force as required by the high density of the product to be supplied, while avoiding that the apparatus is pulled away as it could occur if such a force were exerted to the opposite direction like usually happens in the known dispensers of liquid soap.
- According to another peculiarity of the invention, the thrust of the operating handle through the suitably shaped profile is directed upwards as a consequence of the rotation movement of the handle itself about a pivoting axis at its upper end, thus rendering more efficient the valve action. The valve can also be adjustable according to the various products used, depending upon their density and quantity to be dispensed at each operation.
- According to a further characteristic of the invention, when the container of the product to be supplied is of the disposable type, i.e. a cartridge without filling holes, to be wasted upon use, the dispensing is made easier and the cartridge is prevented from crushing by piercing the latter on the upwardly directed bottom, by means of an element being also a part of the present invention which at the same time acts both as a protection of the pierced holes and as a cartridge cover, possibly having additional own functions, both aesthetically finishing the apparatus at its upper zone, and of utility e.g. by assuming the shape of an ashtray.
- Additional objects, advantages and characteristics of the dispensing apparatus according to the invention will clearly result from the following detailed description of a preferred embodiment thereof, given by way of a non-limiting example with reference to the annexed drawings in which:
- FIGURE 1 shows a longitudinal section view of the apparatus according to the invention along a plane parallel to one of the side walls of the apparatus;
- FIGURE 2 shows a top plan view of the device for locking the container to the apparatus body; and
- FIGURES 3 and 3a show a side view of the bottom portion of the container, being directed upwards in the position of use in the apparatus of the invention, coupled with a piercing, protecting and covering element also having the function of an ashtray, and respectively a top plan view of this element.
- Referring to the drawings, and in particular to Fig. 1, the apparatus of the invention is outerly characterized by a body 1 for supporting and partially housing a
container 2 of the product to be dispensed, preferably moulded in a durable plastic material and securable to a wall with itsrear side 11 in any known manner. Thecontainer 2 may have whichever outer shape, provided that it can be adapted to the body 1 within which the container is housed at the bottom, with the portion corresponding to the outlet opening 21 directed downwards. It could be in particular of the disposable type, i.e. formed of a cartridge to be wasted upon use, or an actual tank to be re-filled with a feed hole at its top. - Near the
front wall 12 of body 1 there is pivotedly mounted on the side walls thereof (not shown in the drawing) an operating lever 3 which is therefore rotatable about a horizontal axis X. The lever 3, which is resistant and of such a size to present a wide contact area, as it may be large almost like thefront wall 12, is advantageously shaped with a handle 3a at its lower portion in order to render easier the gripping by the users during the pull action. The thrust is transmitted through a properly shapedprofile 5, integrally formed with the rear side of lever 3, to a metering valve for unidirectional supply 7. - The valve 7 is of the generally known type, formed of a cylindrical portion of rubber or the like, housed in a suitably
shaped seat 17 which is integral with the body 1 and provided with a lower delivery hole orslot 7a. According to the present invention the metering means of the valve has been modified, as it is formed of a rigid disc 8 sealingly inserted in an upper seat of the valve 7 and provided with openings such ascircular holes 8a for passing therethrough the product from thecontainer 2. A second disc 9 without holes is coaxially mounted under the disc 8 by means of a central pin with riveted head 9a. The disc 9 is movable with respect to the disc 8, as it is generally known, in consequence of the deformation by crushing of the cylindrical wall of valve 7. When disc 9 at its upraised position is pressed against disc 8, theholes 8a are completely closed and therefore the passage of gel into the inner space of valve 7 is stopped, this passage being on the contrary helped through pumping action by the downward movement of disc 9 from the previous position of closure which gives rise to a vacuum zone under the outlet opening 21 of the container. The quantity of product supplied at each operation of the control lever 3 is determined by the total cross-section area ofholes 8a and by the stroke of the shutter disc 9 with respect to the disc 8, being however also function of the density of the product. Therefore, being constant the quantity of the product to be dispensed, possible variations of density of the product will be balanced through a simple operation on the valve 7 without the need of replacing the same. In fact it will be possible to replace the disc 8 only by another having holes of different cross-section, and/or to adjust the stroke of disc 9 by taking an action at the point where the pin head 9a is riveted, which is formed e.g. of thermo-plastic material. - It should be also appreciated that the lever 3 and thereby also the pushing
profile 5 during the operation covers a path shaped as an arc of circle having its centre on axis X, such as to cause a crushing of the cylindrical wall of valve 7 which is not only radial, but has an upwardly directed component being adapted to enhance the maximum delivery of product, thus rendering more efficient the valve action as far as possible. It will also be understood that the outlet opening 7a may be simply formed as a nozzle slot, but preferably also a ball valve could be provided, embedded within the hollow end portion 7b in order to improve both the supply and the sealing, thus avoiding dripping when the apparatus is at rest. This can be simply obtained through insertion of a spherical body, slightly forced, within the hollow space 7b, by keeping the said body upraised from theoutlet 7a not to obstruct the same, such as by means of radial ribs extending from the inner wall of the cavity 7b itself. - As to the safety, in order to prevent a possible removal of the
container 2, there is provided a fastening means 10 substantially formed as a rod-shaped member 13 housed in asleeve 14 integral with the body 1, so as to be able to only rotate therein about its own longitudinal axis and to slide vertically. The vertical movement, parallel to the axis ofmember 13 is however usually prevented by the engagement of aprotruding cam 15 thereof, preferably having a half-ring pattern as better seen in Fig. 2, in aslot 15a formed on therear wall 11 of body 1 and upperly defined by a detent 16 extending into the inside of the apparatus. At the upper end of therod 13 the latter is integrally formed with a tooth orpawl 19 directed to a side opposite to thecam 15, that is towards the front portion of the apparatus, as it is arranged to fit into a suitably shaped cavity provided in the lower portion of thecontainer 2 and having a lower shoulder 22. - At the position shown in Fig. 1 the fastening means is located so as to prevent possible non-authorized operations on the container, because the
rod 13 of a plastic material resistant to mechanical pull, renders in practice thecontainer 2 integral with therear wall 11 of the body 1, while whichever longitudinal movement ofrod 13 is forbidden by engagement of thecam 15 with the detent 16. - To allow that the
container 2 is made free of the fastening means 10 it is necessary that the shoulder 22 is no longer engaged by thepawl 19, what is possible only upon rotation of all therod 13. This can occur only by means of asuitable key 20, available to authorized persons, which engages in any known manner the lower end ofrod 13 by entering thesleeve 14 from below. It will be appreciated that preferably said sleeve extends itself for all the length of the rod, to avoid that portions accessible from the outside may be engaged for rotation by whichever tool such as pliers and the like. - With particular reference to Fig. 2, wherein the
key 20 and the helf-ring cam 15 have been shown by a continuous line at the lock position of Fig. 1 and by broken lines at the disengagement position with thecam 15 being no longer abutting against the detent 16, it may be observed that therod 13 is advantageously integral with aresilient tongue 18, preferably L-shaped, ensuring the return of the locking means 10 to the initial position whenkey 20 is released or pulled out. In fact, during rotation ofkey 20 in the direction of arrow F for unlocking, thetongue 18 bends as shown in phantom while it is elastically loaded to return to the initial configuration as soon as the external action ceases, thus causing therod member 13 integral therewith to return to the initial position shown by a continuous line, which corresponds to the engagement betweenelements pawl 19 and shoulder 22. Thetongue 18 can be advantageously formed by integrally moulding withrod 13 andpieces sleeve 14 there is provided afirst catch 24 to preventrod 13 from rotating in a direction opposite to arrow F by abutment with an end of the half-ring cam 15, as well as asecond catch 24a for avoiding an excessive rotation ofkey 20 and consequently ofrod 13, which could bring to permanent buckling oftongue 18, so as not to ensure any longer the return to the initial locking position. - Referring to Figs. 3, 3a an additional member is shown which, although optional, is a part of the invention. It was states above that the
container 2 may be provided not only as a re-fillable tank, but also as a disposable cartridge to be wasted upon use and, as such, does not have holes in its bottom portion which takes the upper position in use. In order to prevent that the vacuum, which is unavoidably generated in thecontainer 2, may prejudice the uniformity of supply and however cause a deformation of said container, holes will have to be formed on the top thereof. Advantageously according to the invention this can be accomplished by anauxiliary member 30 to be applied to the container, e.g. by causing twolateral guide tabs 31 thereof to slide inassociate seats 32 formed at the upper part of thecartridge 2, toward the rear side. Themember 30 will further comprise at least onepointed nail 33 arranged to enter the cartridge back side by piercing the same at the end of forward sliding ofmember 30 guided by thetabs 31 in therespective seats 32. Therefore, upon application of themember 30 from the back forward, once thecontainer 2 has been mounted to the apparatus and fastened as described above, saidmember 30 cannot be removed but when replacing theempty container cartridge 2. Its function is of covering the holes and protecting the same from a possible misuse, such as the introduction of foreign bodies. Such a member may also have advantageously an aesthetic function of finishing and improving the aspect ofcartridge 2, at its upper portion, in addition to some utility related to the particular shape it can take. For example it could be advantageously shaped as an ashtray, with acentral hollow 34 and at least twogrooves - It will be clear that the above-described and illustrated apparatus with reference to a "hand-washing" gel or paste can be obviously employed also with a usual liquid soap, possibly modifying the supply valve as previously indicated, while maintaining yet most of its advantage of simplicity, handiness and safety of use.
