Abstract
Description
- This invention concerns an improved liquid soap dispenser, of the wall mounted type.
- A number of types of liquid soap dispensers are already known, to be installed mainly in the toilet rooms of public premises, but they are still affected by a number of drawbacks, first among them the fact of requiring, for liquid soap dispensing, that a pulling action be performed in a direction from the wall towards the user, on an actuating lever handle. An action in this direction, besides involving the problem of a possible stripping of the dispenser from the wall, if a large force is applied, necessarily requires the user to insert his fingers on the back side of the handle in order to perform the pulling action. For sanitary reasons, sometimes it would instead be more appropriate to actuate the liquid soap dispensing with a minimum contact against surfaces already touched by others, and preferably by using areas of the body different from the fingers, preferably by means of the forearms, as for instance it is the case for surgeons before entering the operating room.
- Further drawbacks of the liquid soap dispensers are, in addition, a poor accessibility to the internals for supply cartridge replacement, which is in any case by far preferred compared to the use of small tanks or containers refillable from the top, and related insertion of the thin tube or dispensing arrangement, because of the presence of the pushing member actuated through the handle, said pushing member being in turn often subjected to a relatively complicated motion due to the need for accomplishing a double function, i.e. in addition to compressing the side wall of the dispensing tube, also the function of a check valve, i.e. by performing first a complete squashing of the upper region of the tube and then a progressive downwards compression, to assist the liquid in coming out. The above takes place mainly when use is made of disposable supply bags or cartridges, provided with integral dispensing tubes without a check valve.
- Therefore, it is an object of this invention to provide a liquid soap dispensing apparatus which is improved concerning both a simple construction and accessibily to the internals thereof, and especially the provision for an easier, more sanitary and safer actuation concerning the problem of a possible stripping of said apparatus from the point of fastening.
- Said object is met by a substantially box-shaped liquid soap dispenser, whose front wall forms the lid of said apparatus, which can be completely turned over 180°, which lid carries a dispenser actuating lever handle mounted thereon, wich can be actuated by pushing towards the point of fastening of the apparatus, and wherein the pushing member is directly actuated through said handle, being integral or pivoted on the latter around the centerline thereof, in a transverse direction relative to the longitudinal direction of said dispensing tube against which it is preferably constantly bearing, with a slight squashing action, even when the handle is at rest.
- The above and further objects, advantages and features of the dispenser according to this invention vill become more apparent to those skilled in the art from reading the following detailed description of a preferred embodiment thereof, reported herein for exemplary but non limiting purposes, and referring to the attached drawings, wherein:
- Figure 1 is a schematic front view of the dispensing device of this invention, in a closed position;
- Figure 2 is a schematic sectional view, along line II-II of Figure 1;
- Figure 3 shows a partial side elevational view of the device of Figure 1;
- Figure 4 is a front view of the dispenser, completely open, and with the lid in turned over, downwards position.
- Referring now to the attached drawings, the device of this invention comprises a substantially box-like member 1 including a front wall or
lid 2, and aback wall 3 provided with the means for the fastening thereof to a mounting wall.Lid 2 is pivoted relative towall 3, at the lower end thereof, throughopposite pivot pins 5. According to this invention,lid 2 carries a dispenser actuating lever orhandle 4 which can be operated upon by pushing towards the mounting wall, i.e. towards the inside of the apparatus. As it is shown more clearly in Figures 2 and 4, actuatinglever 4 is mounted onlid 2 by being pivoted at 12 around a pair of pivot pins integral with brackets 8 projecting perpendicularly from the lid internal surface, at the end of the handle opposite from the actuating end, and it projects towards the inside of the dispenser by entering anopening 9 provided on the bottom oflid 2. The latter, as it is shown more clearly in Figure 3, is preferably tapered downwards, as it is the case forback wall 3. The portion of actuatinglever handle 4 located inside the dispenser has a pivotedmember 10 adapted to freely oscillate around a pair ofpivot pins 14 defining a transverse pivot axis, parallel to the line connecting thepivoting points 12 of said lever. Stop members (not shown), integral with said handle, limit the oscillating angle ofmember 10 aroundpivot pins 14. Actuatinglever handle 4 is preferably provided, in the portion thereof received within the dispenser, with a raisededge 18, along the whole periphery thereof, projecting in particular from both sides thereof, for the pivot connection at 12 on the pair of brackets 8, and in order to support said oscillatingmember 10, pivoted at 14. - It should be noted that pushing
member 10 may be mounted with a different arrangement onhandle 4, possibly integral therewith, with a certain degree of flexibility to conform in any case to the wall ofdispenser 20. Aresilient member 4a, bearing against the inner surface oflid 2, biases the handle back, towards the rest position thereof, after each actuation. - In particular, as it shown more clearly in Figure 2,
member 4a may comprise a portion integral with said handle, made for instance thinner than the portion to be actuated, in order to give more flexibility. On the side of the lid opposite from the pivoted one at 5, there is provided alock 6, for locking by means of acorresponding stop member 6a provided on the upper side ofback wall 3. - Inside the fastened half-box, comprising
back wall 3 and the side edges thereof, supportingmembers supply cartridge 30 and for dispensingtube 20 respectively. The latter may be any known type and in particular, although not necessarily, like the one provided with the top threaded nut as disclosed and claimed in utility model N.MI91U000498 of the applicant. In this case,support 16 will preferably have a fork-like shape. Provision will as well be made for a wall orshim 17, integral withback wall 3, extending between saidsupport member 16 and the lower region ofwall 3, in order to counteract the action performed bymember 10 againstflexible tube 20, and to cause the latter to be squashed. - It should further be noted that, in order to reduce the stroke of
handle 4,counteracting wall 17 andsupport 16 may be positioned so much ahead as to keeptube 20 in a slightly squashed condition all the time, also at rest. It is emphasized herein that such a condition does not cause any problem in positioning said tube, in that said operation is performed whilelid 2 is completely open, and turned over downwards, then withmember 10 completely out of the way. Only when the lid is closed this may cause the tube to be slightly squashed against the back stopmember comprising portion 17. In this way, liquid can be dispensed with a very short stroke ofhandle 4, which will be completely effective in that there is no play. - As it may be seen on Figure 2, without any meaning of limitation, support
member 15 for a bag orcartridge 30 may be advantageously obtained by molding an undercut onwall 3, whereby material thickness and weight of the apparatus may be reduced, while maintaining a satisfactory mechanical strength. - The bottom of
wall 3 continues, beyond the tapered region mentioned above, in the area of the apparatus center line, wherelid 2 is pivoted at 5, through aregion 19 provided with acentral opening 13 coaxial with dispensingtube 20 and immediately underlying the latter, for liquid soap ejection. Said opening 13 is located at about the same height as the lower side ofhandle 4, in order to be able to collect the dispensed product by the same hand used to operate the handle. It is preferred thatbottom portion 19 is trough-shaped in order to collect liquid soap that while coming out would not pass directly through opening 13, by directing it in any case towards the latter. - It should eventually be noted that the dispensing device of this invention will preferably have the smallest possible size to be able to receive, in the compact box-like shape thereof, the product supply cartridge, in a position as close as possible to vertical, without any need for auxiliary cardboard containers as it is often the case for the liquid soap dispensers known in the art.
- Those skilled in the art will be able to make additions and/or modifications to the above described embodiment of the liquid soap dispenser of this invention without exceeding the scope of the invention. In particular modifications may be made to the outer shape of the body walls and in general to the shape of the parts of the apparatus.
