Definitions
- This invention relates to agitating or mixing devices for aerosol products containing pigments or other materials which tend to settle out during storage.
- Aerosol spray cans containing paints, lacquers, enamels and the like are sold in large quantities. These cans contain the required pigments, a vehicle composed of appropriate resins, oils, solvents and the like in which the pigments are suspended, and a liquefied propellant gas such as dichlorofiuoromethane. Many of them, containing lacquers, enamels, paints and the like formulated to match original factory-applied finishes, are used in refinishing or retouching marred appliances, slightly damaged automobiles and for similar purposes where color matching is of great importance.
- an improved and greatly superior agitating or mixing system for aerosol 3,087,707 Patented Apr. 30, 1963 spray cans having domed bottoms is provided by disposing within the can one or two agitating elements, preferably in the form of balls, that are large enough and of sufficient mass that they can be readily broken loose from the settled pigment when the can is shaken, in combination with several, for example, five to seven, smaller agitating elements, also preferably in the form of balls, that are of such size that they can clean out most of the pigments from the groove between the domed bottom of the can and the side wall thereof.
- FIGURE 1 is a side elevational view, partly in section, showing an aerosol spray can embodying a preferred form of the invention and illustrating somewhat diagrammatically the manner in which pigments or other solids settle to the bottom of the can;
- FIGURE 2 is a fragmentary sectional view showing the manner in which the agitators engage each other in the groove at the base of the can;
- FIGURE 3 is a perspective on the same scale as FIG- URE 1 showing a plurality of agitator balls in the groove at the base of the can.
- the invention is adaptable to a typical aerosol can 10 having a cylindrical side Wall 11 and an upwardly convex or domed bottom 12
- the bottom is domed in order to give it strength to withstand the pressure within the can which may be of the order of 70 psi.
- the bottom 12 is crimped and soldered to the can in a conventional manner as indicated at 13.
- the convex bottom intersects the side wall at an angle of about 60 .to form an annular V-shaped groove 14.
- the upper end of the can 11 is reduced in diameter as shown and has an opening which is closed by a conventional closure cap 15 which supports a valve 16 that may be of any conventional construction.
- the valve has an actuating flap 18. When this is depressed by the user the valve is opened and the pressure of the propellant fluid within the can causes the contents of the can to flow upwardly through a dip tube 19, which is preferably composed of a flexible plastic, to the valve 16 and finally to be discharged from a spray orifice 20.
- the dip tube 19 projects downwardly and is preferably curved toward one side of the can as shown.
- the can when sold is filled to a level near the top of the can with the material 25 to be dispensed.
- the contents of the can consist of a liquefied propellant gas, such as dichlorodifluoromethane, and the paint, enamel or lacquer to be dispensed, which in turn consists of appropriate pigments suspended in a vehicle that includes the usual resins, solvents, oils and the like. Inasmuch as the.
- the liquid portion of the contents of the can is of very low viscosity, and accordingly it is for all practical purposes impossible to prevent settling of the pigments during storage. In fact, for some types of materials settling takes place so rapidly that if it is desired to maintain the desired composition of the material being sprayed, the can should be shaken every few minutes during use.
- the pigments at least in part settle out, as indicated at 26 in FIGURE 1.
- the end 30 of the dip tube is preferably slightly above the level of the settled pigments, as shown.
- mixtures of pigments are employed to obtain desired colors and shades. These pigments generally have different rates of settling. Pigments having a higher rate settle in the groove 14 in greater proportion than the remainder of the pigments and the pigments become somewhat stratified in settling. Therefore, unless most of the settled pigments are scoured out of the groove 14 and mixed with the liquid in the can, the desired color simply will not be sprayed.
- agitation and mixing of the contents of aerosol cans is obtained by employing one or more relatively large agitating elements shown herein as balls 28 in combination with several, preferably five to seven smaller agitating elements shown herein as balls 29.
- one large ball is sufficient, but two or more may be employed if desired.
- the large ball or balls 28 must have sutficient mass to enable it to be broken loose from the settled pigments by shaking the can.
- a diameter steel ball is a satisfactory large agitating element. Balls of this size can be shaken loose from the settled pigment without much difficulty. If substantially smaller balls are employed, however, it may be impossible to shake them loose.
- the smaller balls 29 preferably take the form of conventional lead BB shot. Such shot have a diameter of about 0.18 inch and are readily available at low cost. While BB shot by themselves have insuflicient mass to act as adequate mixers or agitators they work effectively in combination with one or more larger balls or agitators. The reason for the effectiveness of the combination will be evident from a consideration of FIGURE 2 of the drawings. As there shown, the smaller balls or shot 29 go deep enough into the groove so that only a small amount of pigment can remain in the groove if the balls are forced around near the base of the groove. At the same time, the balls are large enough so that they project above the lowest position that can be taken by the larger ball 28.
- the larger ball When the can is shaken the larger ball not only disrupts and breaks loose the solidified pigment but also strikes the smaller balls and moves them around through the pigment, thus securing superior agitation and mixing of the material. It is to be noted that, as shown particularly in FIGURE 3, a lower surface of the larger ball engages an upper surface of a smaller ball and thus tends to force the smaller ball down into the groove where it will do the required job.
- the pigments or other solid materials are suspended in the liquid when the cans are filled and, therefore, the balls simply roll down the domed bottom 12 and remain disposed in the groove in the positions such as shown in the drawings during the time that the goods are in upright position as they normally are on a shelf.
- the pigment or other solid material in the can settles, as shown diagrammatically in the drawing.
- the first few shakes of the can serve to break loose the larger ball or balls from the pigment, and continued shaking causes both the large and small balls to be moved through the pigment and to agitate the contents of the can.
- the engagement of the larger balls with the smaller balls causes the smaller balls effectively to scour out substantially all of the settled-out material from the bottom of the groove.
- one steel ball of about diameter is utilized in conjunction with five to seven lead BB shot.
- the sizes and materials used for the balls may vary within reasonable limits, and the number of balls employed may also be varied.
- the larger ball must be big enough so that it can be broken free from the settled material without too much difiiculty, and the smaller balls should be as small as possible to enable them to penetrate into the groove as far as possible but at the same time they must be large enough so that the large ball and the small balls overlap
- both of the balls are disposed in the groove 14, as shown in FIGURE 2.
- the overlap insures that the small balls can be struck by the larger ball when the smaller balls are as deep in the groove as they can go. Also, they must not be so small that they can become jammed or stuck in the groove and thus made ineffective.
