Definitions

  • the pens structure includes a reservoir, a pump system and an applicator all having a common central axis.
  • An actuating button causes the pump to eject a small globule of liquid thru a normally closed orifice at the center of the applicator, which is located at the bottom of the pen, for easy application to the subject error.
  • FIG. 1 A first figure.
  • This invention appertains to a hand-held type of applicator, equipped with means of metering a minute amount of opaque corrective liquid thru the center of its extremity from where it is applied for such purposes as masking typing and drafting errors.
  • the opaque material being of a fast drying nature, then forms a new fresh surface upon which to make corrections.
  • the applicator of this invention consists, essentially, of the following major component assemblies: the body, which is held in the hand of the user; the applicator tip, being attached to the lower end of the body; a-
  • a pump system also contained within the body and functionable with the reservoir, and by means of which the liquid is forced, in the form of a minute predetermined globule, thru a normally closed axial orifice, or valve, at the extremity of the applicator tip.
  • Aetuation of the pump is accomplished by pressing a button at the opposite end of the central axis of the body from that of the applicator tip.
  • Test samples of the subject invention have been manufactured and demonstrated to numerous secretaries, who normally use corrective fluid applied by a small brush.
  • FIG. 1 is an external view of the pen of this invention.
  • FIG. 2 is the Section 1 1 of FIG. 1'.
  • FIG. 3 is a view of a partial section of the pen of FIG. 2, but showing a different type of check-valve-pump arrangement.
  • FIG. 4 is a view similar to that of FIG. 3 but showing still another type of check-valve-pump design.
  • FIG. 5 shows still another variation of the details of FIG. 1.
  • FIG. 6 shows the piston, per se, of FIG. 1, but with a modification.v I
  • FIG. 7 shows the structure of FIG. 5, but with modified piston of FIG. 6.
  • FIG. 8 shows a modification of the structure of FIG. 6 applied to a modification of the structure of FIG. 2.
  • FIG. 9 is a partially sectioned view showing the pen in FIG. 1, but with a tapered body structure accommodating an inverted conically shaped liquid containing bag.
  • FIG. 10 is the section I 1 through the structure of FIG. 1, as is FIG. 2, except with a modified liquid reservoir and with certain internal components added.
  • FIG. 11 is also the section 1 1 thru the basic structure of FIG. 1, but with additional modifications over that of FIG. 10.
  • FIG. 12 is an end view of the piston-needle assembly of FIG. 11.
  • FIG. 1 the instrument, referred to in this description as the pen, is shown with the applicator tip 1 and the actuating button 2 at the opposite ends of its central axis. It is noted that the lower end of the pen tapers to a narrow dimension to conform to that of the applicator tip which should not exceed 0.125 of an inch in diameter when circular or across its narrow dimension.
  • FIG. 2 The Section 1 1 of FIG. 1 is shown in FIG. 2 and reveals the more important details of the invention.
  • the body element 3 is affixed to the nose member 4, at the lower end, and to the cap member 5, at the upper end of the common central axis.
  • This nozzle 6 engages in the nose portion 4 with a series of mating dimensional steps, as at 9 and 10, which prevent its miss-location when under pressure from action of the piston tip 11.
  • the reversed directional step 12 prevents the nozzle from being forced into the nose member when pressed down upon a surface. A further vital function of this step in dimension will be discussed in the course of this description.
  • the element 13 serves as both a guide bushing for the prismatic piston rod 14 and as a retainer for the resilient nozzle element 6 in order to prevent distortion of the cylinder diameter at 7 when under pressure from engages the actuating rod at 17 and is secured to the nozzle body at 19, is such that, in conjunction with the normally closed orifice at 8, a structure is provided which is capable of being fully charged with the correction fluid as well as being efficiently sealed against the entry of air as the liquid is ejected. Such feature is of paramount importance to" prevent air-locking of the pump system.
  • the collapsible container 16 does just that. It collapses slightly. It is important, however, that the container 16 have a certain amount of wall resistance to collapsing in order that the resulting force of reduced pressure will assist in the rapid and complete closure of the orifice, therefore allowing for the rapid refilling of the cylinder cavity.
  • the reversed step at 12 which was mentioned previously, is designed into the structure.
  • a slight pressure is applied so that the resulting squeezing action closes the orifice completely and forces out all residual liquid.
  • the correction is then rendered smooth by a light gentle circular stroke. Or, if preferable, after the correction is completed, the pen is pressed on another sheet of paper. This secondary operation will serve to clean the pen, as well as, to close the orifice.
  • FIG. 2 presents a complete workable rendition of this invention. However, it is felt that there are variations of the details which could be substituted to produce the same product. Thus, FIGS. 3, 4 and are considered examples of the orifice-valve design.
  • the cylinder cavity 7 is contained within the secondary piston 20.
  • An extension of the piston is the needle valve stem 21 which engages the small open orifice at 22 providing a closure therefore.
  • the compression spring 18 is interposed between the piston 20 and the prismatic piston body cap 23.
  • the normal position of the needle 21 is that of closing the orifice 22 under pressure of the spring 18.
  • the cylinder cavity 7 is communicated with the nozzle channel by the port 25 in the piston head 20.
  • the needle 21 is also lifted rendering the orifice 22 open for the passage of the liquid.
  • the piston 20 is lowered and the orifice is reclosed by the needle 21. This closure occurs when the piston 11 has entered its full length into the cavity 7 and the prisleased the piston 11 withdraws from the cavity 7, the force of the spring 18 retaining the needle in its closed position. Additional liquid then flows past the faces of the prismatic piston body cap 23 and into the vicinity of the cylinder 7 and piston 11.
  • FIG. 4 The structure of FIG. 4 is a variation of that of FIG.
  • FIG. 5 The structure of FIG. 5 is similar to that of FIG. 2, except that the applicator nozzle and nose member are combined as one unit. This is allowed for by the channel 31 being of sufficient diameter so that the section between its bottom extremity and the external applicatorsurface at 32 is relatively thin.
  • the section 32 in which the closed orifice is rendered, then acts as a diaphragm when under pressure from the pump 11. It is also noted that the wall 33 of the nose is relatively thick, and so being, although the material of which the applicator-nose unit is made is semi-flexible, when under pressure effective flexing is limited to the diaphragm resulting in opening of the orifice.
  • closure of the orifice is here assisted by a slight pressure on the applicator end, but in this case, by virtue of the fact that the end 32 is slightly convex. Thus any force against the end will serve to close the expanded orifice.
  • the piston body 14, of FIG. 2 is equipped with a projecting needle 34 as an extension of its axis from the lower end of the piston.
  • a projecting needle 34 as an extension of its axis from the lower end of the piston.
  • FIG. 7 where this piston, with the needle extension, is installed on the nozzle applicator of FIG. 5. It is evident that when the actuating knob is depressed the needle will be caused to pierce the ori fice forcing it open just as the pressure is initiated by the piston 11 entering the cylinder cavity 7. This pilot action of the needle breaks the bond of the hardened residual liquid and the flexibility of the diaphram 32 will allow the passage of the liquid around the needle. This can be further facilitated by making the crosssectional shape of the needle prismatic, or splined, in order that the walls of the orifice will not completely conform to it as the needle enters. This same application can be made to the structure of FIG. 2.
  • FIG. 8 the piston-needle structure of FIG. 6 is shown installed in an applicator nozzle somewhat modified from that of FIG. 2.
  • the bushing 35 serves primarily as a guide for the piston shaft 14.
  • the cylinder cavity is located at the lower end of the nozzle 37, and the tip end of the needle is a straight section comprising the piston at 36.
  • FIG. 9 the pen of FIG. 1 is shown with a tapered shape in order to accommodate a conically shaped liquid containing bag 38.
  • this conical shape is intended to serve a very vital function.
  • the reservoir bag collapses under the resulting vacuum effect and the atmospheric pressure. Such collapsing will first occur at the section of least resistance. Unless the wall thickness is modified, which can be done to predetermine such location, the mid-section between top and bottom will be the normal area of initial and complete collapse. When the latter occurs the liquid remaining in the upper half will be choked off from the pump half of the pen.
  • the top end of the conical structure at 39 being of a longer periphery, will be less resistant to the atmospheric pressure, when under vacuum, and, consequently, will be the first area to experience complete collapsing as the liquid is displaced. Further collapsing will then be progressive toward the pump end. In this manner a more complete use of the liquid, contained in the bag, is attained.
  • FIG. 10 the flexible bag reservoir, of the previous figures, is eliminated. Instead the piston 40 is rigidly attached to the rod just above the pump assembly and normally displaced from the pump piston body cap by the spring 43. One or more small ports are provided through the piston at 40. A suitable seal is shown as at 41.
  • an upper seal member 44 which prevents the contained liquid from leaking past the actuating button 2. Integral with the seal 44 is the air check valve 45 which allows entrance of air as the liquid is discharged from pump end of the pen.
  • the actuating button 2 is depressed causing the piston 40 to be displaced downward.
  • the piston rod 15 is not normally engaged with the piston cap 23.
  • a small amount of displacement of the piston 40 occurs before the displacement of the pump piston 11 is initiated.
  • some of the liquid beneath the piston 40 is ejected as small jets through the ports 42 and serves to agitate the liquid contained above the piston in the reservoir. In this manner a satisfactory dispersion of the pigment portion of the liquid the i is re-established each time the pen is used.
  • the structure works as has already been described for the previous figures.
  • FIG. 10 Like FIG. 10, the cross-section shown in FIG. 11, reveals still additional important details and variations from those presented in the previous figures.
  • an additional mixing or recirculating piston ' is provided by '48 for the purpose of flushing and mixing that portion of the liquid contained within the nozzle prior to the ejection action of the primary piston 11.
  • the prismatic structure as shown in FIG. 6, here is embodied with two primary modifications.
  • the cylinder cavity 49 is incorporated for the purpose of functioning with the piston 48.
  • the channel 50 is provided to communicate the cylinder 49 with the lower portion of the channel contained central within the nozzle 9. This is done by a small tube member 51 at the lower end of which the needle 34 is inserted and secured in such a manner as to provide the small jet ports 52, as seen more clearly in FIG. 12, which is a lower end view of the assembly 34 51.
  • rod 15 extends to 52 within the cavity of the cylinder 49 where it terminates a suitable distance above the bottom of the cylinder cavity.
  • the piston 48 engages the cylinder 49 and forces fluid thru the channel50 and out of the ports 52, as small jets which flush down into the central channel all the way to the lower extremety at 53, thus, forcing any sedimented pigment particles back up thru the central nozzle channel and through the. return channel located around the peripheral surfaces of the assembly 34-51%23 into the cavity 46 where it passes either thru the jet ports 42 of FIG. 10 or around the flexed periphery of 47.
  • a sufficient replacement and agitation of the fluid within the nozzle is assured prior to that portion of the stroke of the actuating button 2 which results in the ejection of the globule thru the orifice 8.
  • a dispensing applicator in the general shape of a writing pen comprising, a central body portion, an upper portion and a lower portion, said lower portion terminating in an applicator surface which has a normally closed central orifice and is located at the lowermost extremety of the applicator device, a fluid reservoir, an interior channel communicating between the reservoir and the orifice, a dispensing pump means for pumping fluid from the channel through the orifice, said dispensing pump means including a pump piston and a pump cylinder located on the central axis of the body portion, an actuating button and connecting rod means passing through the reservoir for operating the dispensing pump means in response to movement of the actuating button.
  • a dispensing applicator according to claim 3 having a resilient sealing member defining the upper end, of the reservoir, said check valve means being integrally formed in said resilient sealing member.
  • a dispensing applicator according to claim 1 having a recirculating passage leading from the channel portion to the reservoir, and circulating pump means for producing flow through the passage from the channel portion to the reservoir prior to entry of the dis--- pensing pump piston into the cylinder section.
  • a dispensing applicator according to claim I having agitator means for producing high velocity movement of fluid within the reservoir, said agitator means being connected to said connecting rod.
  • a dispensing applicator according to claim 11 having a movable conduit communicating between the reservoir and the channel portion, said movable means being rigidly connected to the movable conduit.
  • a dispensing applicator according to claim I having circulating pump: means (48) for pumping fluid from the reservoir into the channel, and a return passage for returning fluid to said reservoir.
  • a dispensing applicator according to claim 19 having a piston means (20)'for moving the obstruction
