FOUNTAIN APPLICATOR Filed Aug. 4. 1955 a M w 2 W w d N 4.6 l 0 M ,JW/2 w m MMM r l Ccm nausea una ac m a 0/3 w j 4 uw J www United States Patent C FOUNTAIN APPLICATOR Sigmund E. Edelstone and Wirt V. Dunlop, Chicago, Ill., assignors to Dupli-Color Products Company, Inc., Chicago, Ill., a corporation of Illinois Application August 4, 1955, Serial No. 526,530 8 Claims. (Cl. 15-139) This invention relates to fountain applicators or fountam. brushes, and has particular reference to such a device of a type having a retractable applicator unit slidably carried by and within an elongated fluid container.
It is an object of the present invention to provide for such a device a novel means for guiding the applicator unit along a generally central path within the container to thereby prevent any undue cramping of the bristles of the dispenser brush as it slides toward and into its operative position projecting outwardly of the container. Another object is to 'provide applicator-guiding means 1n an economical manner.
Other objects, features, and advantages of our invention will be readily apparent from the following description of a preferred embodiment thereof, taken in conjunction with the accompanying drawing, in which:
Figure 1 is a side elevation of the applicator and closure cap, the parts being shown in closed position;
Figure 2 is a longitudinal cross sectional View of such a device according to our invention, with parts in elevation and with parts broken away;
Figure 3 is a longitudinal cross sectional view similar to that shown in Fig. 2, showing the cap removed and with the dispenser brush assembly being shown in its outwardly extending position; and
Figure 4 is a transverse cross sectional view taken along the line IV-IV of Fig. 3. v
As shown on the drawing:
The applicator includes a container, desirably in the form of`a body 12 having a hollow nozzle 14 projecting therefrom, a dispenser brush assembly 16 carried for sliding movement in the nozzle and including a dispenser or applicator such as a brush 18 adapted to project from the forward end of the nozzle, and a closure cap 20 adapted to be applied to the body 12 to cover the nozzlel 14 and the dispenser brush assembly 16. The closure cap 2t) illustrated is of a type which provides for automatic brush retraction by means yet to be described, but the cap could be of a non-brush-retracting type.
The body 12 is shown as having an elongated tubular shape, and has a closed rear end wall 21, and a cylindrical side wall 21a terminating in an open end 22. The body may be formed of any desired material, such as metal, plastic, glass, rubber, or the like.
The nozzle 14 shown is preferably composed of molded, relatively hard plastic material such as Bakelite, hard rubber, or the like. it is generally cylindrical in shape, having a large diameter inner rear end portion 24 press fitted into the mouth 22 of the body 12, and ending in a smoothly rounded tip 28 at the forward end thereof in which there is provided an orifice 30 through which the liquid is adapted to be dispensed.
The applicator unit or dispenser brush assembly 16 is carried within the hollow bore 32 of the nozzle 14. As shown, it includes an elongated plunger or stem 34 at the rear end thereof, a head 36 at the forward end thereof which is adapted to carry the bristles of the applicator brush 18. A spring 40, the rear end thereof rice bottomed against a retainer ring 41 carried at the rear end of nozzle 14, is disposed about the plunger stem 34 to operatively engage the stem as by bearing against the rear end of head 36 as shown, thus biasing the dispenser brush assembly 16 toward the forward, extended position illustrated in Fig, 3. In that extended position the dispensing brush 18 projects outwardly of the nozzle tip 28 through the orifice 30, and the plunger head 36 seals against the tapered inside wall 2S of the nozzle tip 28 adjacent orifice 30 to seal the orifice.- A retracted position of the dispenser brush assembly 16 may be effected as shown in Fig. 2 by the closure cap 20 which carries a brush-retracting pin means 44 which engages the forward end of plunger head 36 to eifect a brushretraction automatically with the closure of the cap onto the nozzle, as by interengaging thread means 45-46 carried by the cap and nozzle; or, brush assembly retraction may be effected by pressing down on the brush 18 to obtain a further charge of liquid to flow through the orifice onto the brush.
A particular feature of the present invention is the provision of a new and improved means for guiding the plunger 34 along a path generally central of the nozzle 14, and which presents the brush bristles 1S generally centrally of the nozzle tip 28 as the brush assembly slides toward its extended position as shown in Figure 3. To
this end, both the forward portion of the plunger and a rearward portion of the plunger are supported generally centrally within the nozzle 14. As shown, means such as the spaced, radially extending lugs 5ft or the like are provided at spaced intervals around the periphery of the plunger head 36. The lugs 50 may be, and desirably are, integral extensions of the plunger head 36, the head and lugs being molded as from a plastic material. These lugs 50 are adapted to engage the nozzle bore 32 to effectuate the desired guiding of the front end of the plunger. Particularly because a rearward portion of the plunger 34 is also guided centrally within the nozzle 14 as is yet to be described, the lugs 50 need not extend fully to the bore 32, but may stop snort thereof as indicated by the clearance 51, permitting wider manufacturing tolerances and ease of assembly. The material to be dispensed flows between and about the spaced lugs 50.
The spring 40, referred to above in connection with its function of biasing the dispenser brush assembly forwardly toward extended position, has a forward portion 56 the turns of which are of a diameter such that they fairly snugly receive the forward end portion of plunger stem 34. Thereby, the forward spring-portion 56 in effect serves to guide the plunger stem 34 rearwardly of the plunger head 36. The rear portion 5S of the spring is provided with a flared or tapered configuration providing a broad spring base which is seated against the retainer ring 41. The broad base-portion 58 of the spring 4!) tapers so that the largest end coil or :several of these coils seat snugly in the nozzle bore. This centers the spring in the bore and provides a centering effect for the forward spring-portion 56, which in turn provides the desired support of the plunger 34 rearwardly of its head 36. Thus rearward support of plunger 34 is effected through the spring 4t).
Moreover, since the larger turns 58 extend outwardly to the diameter of the nozzle bore, and since 'the forward turns 56 fairly snugly receive the plunger stem 34, all liquid to be dispersed must pass between the turns of the spring, thereby obtaining a filter of the fluid to strain out any solids from being dispersed. Furthermore, since during brush-retraction the larger turns at the rear of the spring collapse before collapse of the forward smaller turns, those rear turns effect a seal of the container contents when the brush is retracted, as during a storage condition in which a brush-retracting cap as illustrated is assembled onto the dispenser.
It will be noted from Figure 3 that the interior of the nozzle and body 12 are in full open communication to accommodate free flow of fluid therebetween. If .the liuid is in the form of a suspension such as pigmented paint or lacquer it is desirable to provide a uniform body of the suspension for dispensing to the brush and shaking the device will agitate and mix the contents of both the nozzle and body. To assist mixing an annular weight W can be provided in the body to bottom on the nozzle and receive the plunger or stem 34 freely in the hole thereof. The weight W will reciprocate in the body when the device is shaken and the entire contents of both the body and nozzle will be stirred up and rendered uniform.
We have found that a fountain applicator constructed according to our invention provides a desirable plungercentering and guiding characteristic by novel means providing economy of manufacture and assembly, providing the desired advantages and characteristics, and accomplishing its intended objects including those hereinbefore pointed out and others which are inherent in the invention as described.
lt will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention.
