Description

DILUTION SYSTEM WITH PRODUCT CLOSURE BACKGROUND OF THE INVENTION Field of the Invention This invention relates generally to a dilution spout and more particularly to a dilution spout having a product seal and also to a dilution spout.

Description of the Previous Technique It has been used for a long time the dilution apparatus using a vacuum cleaner, to dilute a liquid concentrate with a liquid diluent to form a solution of use, the first of such systems were by the way, loose assemblies of pipe, connections, vacuum cleaners, etc. . The typical dilution station of the prior art comprises a large concentrate container, a diluent source, typical service water and a receiving container for the diluted use solution. Such a dilution apparatus is operated by passing the service water or other aqueous stream through the aspirator containing a Venturi tube. A Venturi tube extracts the liquid concentrate from the volume in contact with the aqueous diluent stream, mixes the diluent and concentrates forming a use solution which is then transferred to a container of use solution. The configuration of such dilution apparatus has taken a variety of modalities. A large number of embodiments of the concentrate containers, transfer mechanism, aspirator control means, use solution containers and various combinations of those elements have been tried in the past. In the past, the prior art dilution systems had a hose or conduit at the end of the Venturi tube for the supply of the use solution. This conduit is simply placed inside the bottle or container to receive the use solution. When a plurality of dispensers are used, for a plurality of chemicals, there is no control or mechanism to prevent a first chemical product from being placed in a bottle that was designated and labeled for a second chemical. Even more, when the jet is activated, it is often necessary to place the conduit in the bottle and then, with the other hand, activate the spout. There are prior art dispensers that are activated by backward pressure of the bottle in the same direction as necessary to push the switch that activates the dispenser. However, it is often more convenient from the design point of view to have the activation button to move it in one direction and the movement of the bottle in the other direction. However, in the devices of the prior art, it is not possible to have the movement of the bottle in one direction that activates the switch in another direction.

Accordingly there is a substantial need for a new versatile dilution apparatus and dilution stations having one or more dilution apparatuses. Such stations will ideally allow the supply of a variety of chemical products within corresponding closed bottles to ensure that the correct use solution is supplied within the correct bottle. In addition, there is a substantial need for a dilution apparatus wherein simple movement of the bottle in a first direction within the dilution apparatus will activate a switch, which moves in a second direction to initiate the assortment of the use solution.

DETAILED DESCRIPTION OF A PREFERRED MODALITY The apparatus of the invention for diluting a liquid concentrate for a diluted liquid use solution contains a vacuum cleaner. The aspirators contain a Venturi device driven by water pressure to extract a concentrate. The Venturi device comprises a nozzle opening associated with a concentrated solution body. The speed of the diluent through the nozzle causes a reduction in pressure, extracts the concentrate inside the vacuum cleaner, usually causing a mixing of the concentrate and the diluent typically in a fixed ratio that depends on the pressure, sizes and length of the pipe. Once diluted and mixed, the diluted use solution leaves the vacuum cleaner through an outlet for the diluted use solution. the outlet is in liquid communication with the container of the use solution. The aspirator is typically dimensioned and adapted for the diluent pressure ranging from about 0.703 to about 4,218 kg / cm2 gauge. Preferably, service water is available in most municipalities at a pressure of approximately 1,406 to 2,812 kg / cm2 gauge. The apparatus of this invention works best at such pressure. However, the apparatus can be adapted to a variety of water pressures. The concentrated materials of the invention include general purpose cleaning and sanitizing materials, coating compositions and other institutional or industrial liquid concentrates. Such materials include window washers, hand soap, hard surface cleaners, floor cleaners, sink cleaners, tile cleaners, drain cleaners and drain openers, glass cleaners, cleaners for food preparation units, sanitizers , disinfectants, aqueous coating compositions, water reducible concentrates, water-reducible floor finishes, aqueous wax dispersions, air coolants, odor neutralizers and other similar concentrates that can be formed as an aqueous solution, an aqueous alcohol solution, a aqueous dispersion, a reducible aqueous solution or dispersion, etc. The liquid concentrate materials useful for dilution for a diluted use solution include aqueous solutions, aqueous suspensions, aqueous reducible concentrates, aqueous alcohol concentrates, etc., of. chemical cleaning or sanitizing products. The concentrate may contain about 20 to 90% active cleaning materials. The typical viscosity of liquid concentrates typically ranges from about 1 to 400 cP. Chemical systems may comprise a based cleaner, an antimicrobial, a floor finish, etc. The cleaner can be a generally neutral system, an acid-based system containing a compatible surfactant, cosolvents and other additives or alkaline systems containing a source of alkalinity, compatible surfactants, co-solvents, etc. The apparatus is typically adapted and configured to dilute a variety of liquid concentrates for useful concentrated use solutions. Cross contamination should be avoided. Acid cleaners can make basic cleansers inoperable. In addition, the addition of a chlorine source to an acid can release toxic fumes. A variety of other inappropriate interactions can occur resulting ultimately in a use solution that is not adequate for its intended purpose. An apparatus for diluting a liquid concentrate with a liquid diluent to form a dilute use solution for assortment within a bottle is generally described at 10. The assortment apparatus 10 includes a housing 20 which includes a cover 21 and a base 31. The cover 21 and the base 31 can be formed from any suitable material such as a suitable molded plastic. The cover 21 is secured to the base 31 by suitable means such as screws 22. The cover has two access openings 23 on its side portion. As shown in Figure 1, only one access opening 23 is shown. However, as will be more fully described hereafter, a similar access opening is placed on the opposite side of the cover 21 to allow access for the diluent. Formed at the bottom of the cover 21 is an opening 24. The opening 24 is best seen in Figure 8. The bottom of the housing 20 has a first surface 25 which, when mounted, it is at a slight inclination towards the horizontal. A second surface 26, in which the hole 24 is formed, is generally horizontal when the spout 10 is mounted. A flange 27 is formed between the two surfaces 25 and 26. The flange 27 has a rectangular groove 27a formed therein. A screw opening 26a is formed in the second surface 26. This structure forms the base for mounting of several closure members. Several modalities of the closing member are shown. Figure 5 is the closure member 100, Figure 6 is the closure member 200, Figure 7 is the closure member 300. Closing member 300 will be described in more detail with reference to Figures 7, 8 and 10. The closure member 300 has a generally planar surface 301 in which an opening 302 is formed. The surface 301 has a tongue 303 and a screw opening 304. The tongue 303 is inserted into the slot 27a and the screw 305 is inserted through the screw opening 34 and fastened within the screw opening 26a to secure the closure member 300 in the housing 20. The closure member 300 has a collar 306. The collar 306 extends into the cavity of the housing 20. The collar 306 is positioned proximate the member 80d of the sliding actuator 80. As best seen in Figure 7, the opening 302 has a geometric cross-section of a hexagon. The closure member 300 is designated for use with a bottle 40, as shown in Figure 1. The bottle 40 is a bottle in which the use solution will be supplied. The bottle 40 has a generally cylindrical bottom portion to receive the use solution. The bottle 40 has a neck 41 that is smaller in diameter than the cylindrical portion. The neck 41 has a geometrical cross-sectional configuration of a hexagon engaging that of the closure member 300. Therefore, the neck 41 is capable of passing through the opening 302 as it has a configurable cross-sectional shape. At the top of the neck 41 is a threaded opening 42 for receiving a lid (not shown). Figure 5 shows a closure member 100, which, similar to the closure member 300, has a flat surface 101, the opening 102, the tongue 103, the screw opening 104. The cross-sectional configuration of the opening 102 is circular with four tabs at 90 ° that project inwards. A collar 106 extends inwardly and has the same cross-sectional configuration as the opening 102. Figure 6 shows another example of a closure member 200 having a flat surface 201, opening 202, tongue 203 and aperture 202. screw 204. The cross-sectional configuration of opening 202 is generally circular with six tabs projecting inwardly. A collar 206 has a cross-sectional configuration as the opening 202. Figure 2 illustrates a bottle 40 'for use with the closure 100. The bottle 40' has a generally cylindrical bottom portion for receiving the use solution and a portion of neck 41 'having a geometric cross-sectional configuration which engages the closure 100. It is understood that the different configurations can be used. An important factor is to designate a cross section configuration that only accepts the geometric configuration that is similar to the closure member opening and does not allow other geometric configurations of similar size to pass through it. That is, the bottle 40 'would not pass through the closure member 300 or 200. Similarly, the bottle 40 would not pass through the closure members 100 or 200. This is important, as will be more fully described below. successively, to prevent the filling of a specific bottle with the wrong chemical use solution. A plate The drip tray 38 is inserted under the housing 20. The base 31 has a rectangular slot 31a under which a lip of the drip tray 38 is inserted. This intertrabado holds the drip tray 38 under the housing 20. The drip tray 38 has a base member 38b on which the bottom of a bottle to be filled can rest. The distance between the upper part of the base member 38b and the bottom of the housing 20 is greater than the height of the bottle in which the use solution will be placed. The base 31 has two wedge slots 31b that can be used to mount the spout 10 to a suitable mounting surface such as a wall 99. A controller or valve 50 is mounted to the base 31 by means of screws 51. The controller or valve 50 can be any valve such as the model 633 B-EL valve assembly, made by Dema Engineering of St. Louis, Missouri. The controller 50 has a valve body 52 and side mounting plates 53. The screws 51 are positioned between the side mounting plates 53 and the valve body 52. The pipe plug 54 is operatively connected to the valve body 52. The valve 50 has an inlet 55 to which a connector 56 is mounted. Inlet 55 and connector 56 extend out of housing 20 through an aperture sized and shaped as access opening 23. Connector 56 is adapted to receive the diluent inlet hose 57. Mounted to the valve body 52 is an activation sh 58. The activation sh 58 includes a body 58a on which a press-fit button 58b is mounted. The button 58b is mounted on the body a spring that biases the button away from the valve body to a deactivated position. The valve body 52 has a threaded outlet 59. A vacuum cleaner 61 is in fluid communication the outlet 59. The vacuum cleaner-60 can be any suitable model such as the Air Gap Proportioner 4GPM number 10070400 made by Hydro Sytems Company of Cmcinatti, Ohio In the embodiment shown, the aspirator 60 is an air gap aspirator. The aspirator 60 has an inlet 61 that is in fluid communication the outlet 69. The aspirator 60 includes a ventup tube having an inlet that is in fluid communication. a shoulder 69 One end of the shoulder 69 is connected to the inlet of the Ventup tube and the other end has a tongue connection to connect to a conduit (not shown) which in turn is placed in a liquid concentrate container (not shown). shown) previously described The aspirator has an outlet 62 that is in fluid communication an outlet conduit 63 In this particular model of the aspirator, the outlet conduit 63 is a double conduit The inner conduit supplies the diluted use solution and the other conduit conducts any diluent spilled into the bottle 40 A bracket 70, as best seen in Figures 2 and 4, is secured by means of screws 72 to through a hole 71 The screws connect the bracket 70 to the controller 50 The bracket has a first sliding member 73 connected to a second sliding member 74 by an intermediate member 75 The first sliding member 73 has a rectangular groove 73a and the second rectangular member 74a has a rectangular groove 74a The intermediate member 75 has an opening 75a through which the ^ ßferfaotrteV'éet jre-u'oi? (Eud s_cte * 9teóo: e5aaay pweió ^ eíé? ras ^ icádogißar) is inserted. 75c access The holes 75c allow access in order to hold the screws 51 that connect the controller 50 to the base 31. The rectangular slot 73a is separated closer to the intermediate member 75 than the rectangular slot 74a. A sliding actuator 80 has a first portion 80a that connects a second section 80b by an angled (or inclined) intermediate portion 80c. At the end of the first portion 80a is a downward hanging member 80d. As shown in Figure 9, this member 80d has a groove 80e through which the outlet conduit 63 can be inserted. The first portion 80a is inserted through the rectangular groove 73a and the second portion 80b is inserted into the groove 80a. the slot 74a. The bracket 70 is typically made of plastic and is therefore deformable to allow the second portion 80b to be inserted into this rectangular groove 74a. Motion limiting detents 81 are positioned through the entry holes in the first portion 80a. These detents 81 limit the linear movement of the sliding actuator, as will be discussed more fully hereinafter. Referring to Figure 2, in use, a bottle 40 'having a correspondingly coined collar 41' for the appropriate closure 100 ', it is placed on the base member 38b of the drip tray 38. In this position, the upper part of the bottle is separated away from the bottom of the housing 20. The duct 63 is placed inside the bottle 40 '. Typically, since the conduit 63 extends into the bottle when it is placed on the base 38a, it is usually advisable to insert the conduit into the bottle as it is placed under the housing 20 and on the drip tray. Then, the bottle 40 'is moved upward, as shown by the shaded lines in Figure 2. This is generally parallel to a longitudinal axis of the duct. It is necessary to orient the neck 41 'of the bottle 40' to allow it to pass through the opening 102 and make contact with the member 80d of the sliding actuator 80. Afterwards, it forms the continuous bottle by moving upwards the sliding actuator 80 moves towards above, as shown by shaded lines in Figure 2. When the sliding actuator is in a first (unused) position, the button 58b extends fully and is under the second portion 80b. Then, as the sliding actuator moves to the second position (use), the inclined portion 80c contacts the button 80b and presses it downward as the sliding bracket moves in a direction substantially parallel to the longitudinal axis of the conduit 63. movement of the button 80b is in a direction substantially perpendicular to that of the movement of the bottle 40 '. However, it is understood that other angled relationships with the present invention can also be used. The angle of the slope is approximately 30 °. It is preferable that approximately 1,905 cm of displacement of the sliding actuator causes approximately 1.27 cm of movement of the button. With this movement of 1.27 cm, the button is pressed afterwards and the spout is activated. That is, the controller 50 then allows a use solution to enter the valve body 52 through its inlet 55. The water then exits through the outlet 59 through a nozzle and is sprayed through the venturi tube of the vacuum cleaner 60. This in turn causes the liquid concentrate to be collected through its inlet 61 from the liquid concentrate (not shown). It is well known in the art how a conduit is connected to the tab end of the shoulder 69 and is placed inside a liquid concentrate container. Then, the diluted use solution leaves the outlet 62 inside the outlet conduit 63 and finally inside the bottle 40 '. The detents prevent excessive movement of the sliding actuator and properly position the sliding actuator. The closures 100, 200 and 300 are color-coded to their respective bottles. That is, the bottle that has the same geometrical cross section configuration since the closure will have a color label of the same color as the closure. This will help the operator to ensure that he fills the bottle with the correct use solution. Figure 3 shows a dispenser system including a plurality of dispensers 10, 10 'and 10. The dispensers 10' and 10"are identical to the dispenser 10, except that they use a different closure member. When used in a system such as that shown in Figure 3, three different liquid concentrates can be dispensed. Each of the dispensers 10, 10 'and 10"have a different closure member associated with them. Therefore, the three bottles, each having a corresponding cross section configuration such as the opening of the closures, would be used with each spout. The bottle that is in use in the spout 10 ', will not be able to enter the spout opening 10 or 10". , the bottle would not be able to activate the wrong assortment since it would not be able to move the sliding actuator 80 since it would not be able to pass through the opening of the closure. Another feature of the present invention is that the closures are replaceable. is, of course, it is desirable that the correct bottle is used, there may be certain circumstances where an operator would run out of a bottle type. In such a case, the closure can easily be removed by simply removing the screw and lifting the tab out of the opening. , the complete opening 24a is available for a bottle that is inserted to drive the sliding actuator 80 The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention Since many embodiments of the invention can be made without departing from the spirit and scope thereof The invention resides in the appended claims to the present
