United States Patent 3,209,994 POSITIVE-PRESF'URE (I@NTROLLEB-ATMO- PHERE LIQUID DISPENSER Benjamin L. Levinson, Miami, and Edward E. Brush,
Coral Gables, Fla., assignors, by mesne assignments, of one-half to Evelyn Levinson, Miami, Fla, and onehalf to said Brush Fiied Apr. 16, 1963, er. No. 273,495 16 Ciairns. (Cl. 222-82) This invention relates to liquid dispensers, and more particularly to such a dispenser for handling a liquid which is sensitive to exposure to air.
The general object of the present invention is to improve bulk liquid dispensers. A more particular object is to provide a dispenser in which the liquid is exposed to a desired or controlled atmosphere, usually an inert gas.
A further object is to provide a dispenser in which the liquid and gas are under positive pressure so that any leakage is outward, thereby further guardin against contamination of the liquid in the dispenser.
The liquid is supplied in a bottle having a threaded neck receiving a threaded cap, and the end of the neck is additionally sealed by means of an easily penetrable membrane. The threaded cap serves primarily for physical protection of the membrane until the bottle is ready for use. In accordance with a feature and object of the invention, the bottle is provided with a long neck, and the bottle and a bottle holder receiving the same are each provided with a slip seal part and a pressure seal part,
the slip seal taking effect before penetration of the membrane, and long before the pressure seal would be able to take effect.
The invention is here shown applied to a dispenser for hair dyes for use in beauty parlors, although the invention is also useful in medical, chemical, or other industries dealing with a liquid which must not be exposed to oxygen or air. The usual hair dye is such a liquid, and it istherefore packaged in small one-ounce or two-ounce packages, because once opened the dye deteriorates. This is particularly wasteful when seeking to mix different colors, because only a small part of each package is used, and the rest must be discarded.
One specific object of the present invention is to overcome this ,difliculty, and to provide a dispenser for hair dyes. The dispenser preferably includes an array or bank of bottles containing dyes of different shades or .colors, each bottle having its own dispensing spout and valve, but all of the bottles preferably being supplied with an inert gas from a single tank.
To accomplish the forgoing objects, and other more specific objects which will hereinafter appear, our invention resides in the liquid dispenser elements and their relation one to another, as are hereinfater more particularly described in the following specification. The specification is accompanied by drawings in which:
FIG. 1 is a fragmentary perspective view showing a single dispensing unit;
FIG. 2 is a vertical section drawn to larger scale;
FIG. 3 is a transverse section taken approximately in the plane of the stepped line 3-3 of FIG. 2;
FIG. 4 is a fragmentary section corresponding to the right end of FIG. 2, but showing a different type of con- ,trol valve;
FIG. 5 is a section corresponding to the middle or :socket portion of FIG. 2, and shows the relation of the parts after a bottle has been screwed allrthe way into the socket;
FIG. 6 shows a capped bottle, drawn to small scale; FIG. 7 is a perspective view explanatory of how a bank or row of dispensers may be mounted on a panel over a gas tank;
FIG. 8 is a perspective view showing a different form of holder and bottle neck;
FIG. 9 is a perspective view showing a different type of cabinet, equipped with a bank of dispensers of the type shown in FIG. 8;
FIG. 10 is a perspective view looking toward the rear of the cabinet with its back open;
FIG. 11 is a vertical section through a holder generally like that shown in FIG. 8;
FIG. 12 is a section taken approximately in the plane of the line 12-12 of FIG. 11; and
FIGS. 13, 14 and 15 show successive stages in the application of a bottle to the holder of FIGS. 11 and 12.
Referring to the drawing, and more particularly to FIG. 1, the dispenser comprises a bottle 12 having a relatively long neck which is received in a holder 14 having a socket 16. The liquid is dispensed from a spout 18 under the control of a handle or knob 29. There is provision for a gas connection 22 inside a panel 24, through which panel the holder passes and on which it is mounted.
Referring now to FIG. 5, the bottle 12 has a long neck 26, with a threaded portion 28 at the end, and with a slip seal portion 30 which is larger in diameter than the thread and which is located between the threaded portion and the body of the bottle. Referring to FIG. 6, the bottle 12 and neck26 are initially capped by means of a conventional protective screw cap 32. When this cap is removed the bottle remains sealed because the end of the neck is initially provided with a thin, easily penetrable membrane shown at 34 in FIG. 2, and a remnant of which is shown in FIG. 5.
The socket 16 (FIGS. 2 and 5) has a threaded part 36, and a slip seal part 38. The base of the socket has a gasket 40 which receives the end of the neck with a pressure seal. The parts are so proportioned in axial direction that the slip seal parts 30 and 38 provide a seal as the bottle is being put into the socket, and well before the neck end reaches the gasket 40. The slip seal should and does come into effect before the membrane 34 is penetrated.
Referring now to FIG. 7, there is a tank 42 of a gas which is inert and/or compatible with the liquid being dispensed. In this case the gas is nitrogen. The gas inlet tube is indicated at 44 (FIG. 2) and 46, and provides connection from the gas tank into the base of the socket 16. A check valve 48 is located in the inlet tube 46. There is also a liquid discharge tube 59 leading from the base of the socket 16 to the spout Iii. A dispensing valve 52 is disposed between the discharge tube and the spout 18. The valve shown inFIG. 2 is a pull valve, and is operated by pulling the knob Zilagainst a compression spring 54.
Considering the arrangement in greater detail, the present dispenser is intended for use with hair dyes. The bottle 12 is made of glass, and in the particular case shown is about 2 /2 inches in diameter and ten inches long and holds sixteen ounces. The membrane 34 is made of metal foil. The holder is made of stainless steel.
The neck of the bottle is made cylindrical at the slip seal portion 30 (FIG. 5), and the socket part 38 is grooved to receive and hold two spaced 0 rings 60. One slip seal part is cylindrical, and the other has annular rings or beads for slidably engaging the cylindrical part. The beads have the same diameter and in that sense both of the slip seal parts are effectively of uniform diameter to provide a slip seal in axial direction. The bottom gasket .0 also may be an O ring, but in such case it is of smaller diameter than the 0, rings 64). The 0 rings are preferably made of a product called Vit-on, commercially available from E. I. du Pont de Nemours Company. However, the 0 rings also may be made of Teflon,
but in such case are preferably cored with rubber to make the same more resilient. When Viton is employed it preferably has 70 durometer hardness. Both Viton and Teflon resist attack by the hair dye.
Referring to FIG. 2, the holder in this case comprises a horizontal member 14, the rear end of which has means for mounting the same on the upright panel 24. In this case the rear end is necked and externally threaded at 62, and receives a nut 64. Metal washers 66 may be employed for appearance and strength. The rear end may be internally threaded to receive a nipple 68 having a slender tubular extension 70, which is surrounded by an expansible tube 48 which acts as a check valve to prevent fiow of liquid back through a nipple 68. The outer end of the nipple receives a tube or pipe 44 which extends to the gas tank.
The spout 18 depends from the forward portion of the horizontal member 14, and the socket 16 is mounted on the top center of part 14, the parts preferably being made of stainless steel, and being welded or brazed together. The valve has a horizontal valve stem 72, the inner end of which carries a plug 74 which is made of a plastics material which resists attack by the liquid. In the present case the plug is made of Teflon. It has a frusto conical end which bears against a mating valve seat 76. The valve stem passes through a bushing 78 which is threaded into the forward end of member 14, and is sealed by a gasket 80. The valve stem is itself sealed by an O ring or other packing 82, compressed by the main compressing spring 54, a suitable washer 84 being interposed between the spring and the packing.
The horizontal gas inlet passage 46 is continued vertically by means of a passage and a pipe 86, the upper end of which serves to rupture the membrane. For this purpose it may be sloped as shown at 88. The vertical passage is preferably extended downward for ease in manufacture and for cleaning purposes, and in such case the lower end is closed by a suitable plug 90.
The check valve tube 48 is made of a yieldable material appropriate for the liquid being handled, and in the present case may be made of Viton. When a new bottle is being loaded into the dispenser, it is started down until the slip seal takes effect but the membrane is not broken.
Gas is then supplied. The knob 20 is pulled to permit a nitrogen flow which purges the space in the socket and valve, etc. The knob is released and the bottle then screwed all the way into the socket.
A modified form of valve is shown in FIG. 4 which figure corresponds to the right end of FIG. 2. In FIG. 4 the forward end of the horizontal part 14 again has a spout 18 and a horizontal valve stem 92, but in this case the valve is a screw valve instead of a pull valve. More specifically, the valve stem 92 is threaded at 94 and is received in a bushing 96 which is internally as Well as externally threaded. The inner end of the valve stem again has a valve plug 98, which is preferably made of Teflon, and which engages a valve seat 100. The valve stem is sealed within bushing 96 by means of an O ring 102, and the bushing is itself sealed by a gasket 104. The knob or handle 166 may be like that previously shown, but it is manipulated by rotation instead of being pulled. The pull valve of FIG. 2 has the advantage that it cannot be left on. The screw valve of FIG. 4 has the advantage of more gradual and precise flow control.
Referring now to FIG. 7, the complete dispenser in this case has seven bottles, one of which is indicated at 12, and the other six of which are located on the six center lines indicated at 110, 112, 114, etc. The bottles are alike, and are received in like holders, all of which are mounted on a single panel 24. The gas tank 42 is housed beneath the holders, and access is gained by an openable back 116. It will be understood that the tank 42 may be a conventional commercially available nitrogen tank provided with the customary valve 118, which facilitates connection of a new tank to a manifold or distribution pipe which leads to all of the holders 14. The pressure may be regulated by a conventional pressure regulator 119.
As so far described, the slip seal portion of the neck is cylindrical and is received in 0 rings, but this is not essential. Another form of the invention is illustrated in FIGS. 13, 14 and 15 in which the neck 128 of the glass bottle has one or more annular beads 122 which have a rounded exterior configuration. The slip seal portion 124 of the socket 126 is lined with a cylinder 128 of a yieldable non-corrosive material. In the present case the lining 128 is made of Teflon. In FIG. 8 there are two spaced annular beads 134, 136. Again there are mating slip seal parts one of which is cylindrical and the other of which has one or more annular beads, but the beads act like a cylinder of uniform diameter for purposes of axial slip. The bottom gasket 136 is also made of Teflon, and in this case is a fiat gasket. By comparison of the successive stages illustrated in FIGS. 13, 14 and 15 it will be seen that the thread and slip seal are engaged first, and before the membrane 132 is broken as shown in FIG. 14, and the slip seal is maintained until the pressure seal is established at 130, at which time a double seal is provided.
There may be more than one annular bead, and FIG. 8 illustrates the use of two annular beads 134 and 136, received in a cylindrical Teflon lining 138. In such case the final seal is a triple seal.
The holder illustrated in FIGS. 8-15 differs struc turally from that previously described. It includes a U shaped sheet metal housing 140, the rear edges of which are shaped to provide four slotted anchoring lugs 142. The holder is mounted on a metal panel shown at 144 in FIG. 9, the latter having slots mating with the lugs 142 (FIG. 8). The holders are detachably locked in position by a suitable lock 146 (FIG. 8). The gas connection is provided at 148, and liquid is discharged at a spout 150 under control of a valve knob 152.
Referring now to FIGS. 11 and 12, the socket 126 is the upper part of a cylindrical body 154 which is held within the jacket previously mentioned. It may be secured in place by appropriate screws 156. It has two vertical passages, one shown at 158 for liquid discharge, this passage being plugged at the bottom by a screw plug 160. It is somewhat sidewardly displaced from but intersects a horizontal valve passage 162. The stem 164 (FIG. 12) of pull valve 166 passes through the front, while the spout is connected at the rear as shown at 168. In this case the valve seat 170 is made of Teflon, while the valve plug 166 is made of stainless steel, it being sealed by 0 rings made of Teflon or Viton.
There is also an upright gas inlet tube 172 (FIG. 11) and a check valve is provided at 174, which in this case is a ball check valve resting on a Teflon seat 175. The gas connection from the rear leads to the vertical passage at 176 (FIG. 11 and also FIG. 8).
FIGS. 9 and 10 show a modified dispenser'cabinet for an array of bottles. Referring to FIG. 9, the cabinet is open at the front to expose seven bottles and holders, but it will be understood that a lesser or greater number may be provided. Referring next to FIG. 10, the gas tank 180 is upright and is stored behind the dispensers. A pipe 182 leads to a manifold pipe 184, from which seven pipes 186 descend and turn forward to the seven dispensers. The tank has a valve 181, and a pressure regulator 183, followed by pipe 182. The pressure employed need not be great, and the pressure, regulating valve 183 is adjusted to maintain a suitable low pressure,
say, five pounds per square inch. The back 188 of the cabinet may be used for storage of reserve bottles 190.
r If desired, the slip seal portion of the bottle neck may be ground for greater precision. However, it is preferred not to grind the glass, not only to save theexpense of a grinding operation, but also because removal of the original skin of glass greatly weakens the glass structure.
The slip seals here shown will operatewith a tolerance which is obtainable commercially without grinding. For example, the cylindrical part 30 in FIG. 5 may have a dimension ranging from 1.161 to 1.186 inches.
Here again when loading a new bottle it is started; the air then purged by flowing gas through the socket and valve; and the bottle then screwed home.
It is believed that the construction and method of use of our improved positive-pressure controlled-atmosphere liquid dispenser, as well as the advantages thereof, will be apparent from the foregoing detailed description. It will also be apparent that while we have shown and described the invention in several preferred forms, changes may be made without depaitingfrom the scope of the invention, as sought to be defined inthe following claims.
