Abstract

An applicator for applying a fluid to a surface comprises an applicator tip element (5) connected to the end of a substantially rigid stem (1) by a part (3) capable of flexing resiliently as the applicator tip element is stroked across a surface. The application element is conveniently formed as a pad or a moulded member of porous material e.g. foam, which can be attached in various ways, e.g. by means of adhesive, heat welding or mechanical fixing, to the resiliently flexible connection part.

Description

CA 0224017~ 1998-06-10 ~' Fr~UID ~PPLICATORS
This invention relates to applicators used to apply a fluid substance onto a surface. The invention i8 principally concerned with, and is specially described herein in relation to applicators for applying a correction fluid to a paper sur$ace to facilitate the correction of typing or writing ~istakes. It is known to ~upply correction fluid in a bottle provided with a cap which incorporates an applicator having a rigid stem ext~n~;ng from the underside of the cap, and an application element, most often a brush, carried at the free end of the stem. By holding the cap, the brush can be dipped into the fluid cont~;ne~ in the bottle to pick up a small portion of the fluid, and by applying the brush to the surface of a sheet of paper a fairly broad band or stripe of correction ~luid can be deposited onto the paper. When not in use, the cap is secured to the bottle, e.g. by a screw-threaded conn~ction, and the applicator is conveniently stored within the bottle. On the whole the known applicators of this kind work well. However, it can be difficult to lay down a stripe of fluid with uniform thickness and width over more than a short distance along the paper, e.g. when attempting to cover over complete words or more than one word, at least with a single stroke of the brush. As a consequence it is frequently necessary to stroke the brush along the paper several times, which is inconvenient.
In accordance with the present invention CA 0224017~ 1998-06-10 WO97/21554 PCT~S96/19885 there is provided an applicator for applying a fluid to a ~urface, compri~ing an applicator tip element connected to the end of a substantially rigid stem by a part capable of flexing resiliently a~ the applicator tip element iR stroked acroRs a surface.
The application element 8hould be capable of ab~orbing a portion of fluid when dipped into a body of the fluid, e.g. contained in a bottle, and of holding thi~ fluid portion until the application element is applied to a surface. ~he application element i~
conveniently formed as a pad or a moulded member of porous material e.g. foam, which can be attached in various ways, e.g. by means of adhesive, heat welding or m~Ch~i cal fixing, to the resiliently flexible connection part. It is also possible for the application element to be made of porous material and to be formed integrally with the resiliently flexible part.
The resiliently flexible part can be integral with the ~tem or it can be a separate part fixedly ~ecured to the stem, e.g. by a root portion thereof being insertQd into a bore provided in the end of the 3tem.
The resiliently flexible part may be capable of flexing in any directionr or it can be adapted e.g.
tn the manner of a living hinge, to define a predet~r~;~e~ axi~ about which the application element can pivot relative to the stem while being restrained against deflection in other directionR.
The resiliently flexible connection pa~t preferably allows the application element to deflect ~rom a position substantially aligned with the Rtem to a po~ition substantially at 90~ thereto. When the application element is applied to a ~urface with a natural stroking action, which varies the ansle at which the stem is inclined to the surface, there is a tendency to increase the force with which the CA 0224017~ 1998-06-10 WO 97/21554 PCT/US96~I98~5 application element presses against the surface.
However with an applicator according to the invention, the application element can deflect due to the resiliency o~ the connection part, and the force against the paper does not vary greatly throughout the 3troke. As a conse~uence the rate at which fluid is delivered onto the surface at the end of the stroke is not substantially different from that at the beginn;ng of the stroke and a uniform stripe of fluid is 10 obt~;neA.
A full underst~nA;ng of the invention will be gained from the following detailed description of some ~hoA; ts, reference being made to the accompanying drawings, in which:
Figure 1 shows a first applicator embodying the invention;
Figure 2 illustrates the flexing capability of the applicator tip of the Figure 1 applicator;
Figure 3 is similar to Figure 2 but Rhows a modified construction;
Figure 4 shows another applicator embodying the invention;
Figure 5 is a side view of the connection component of the applicator in Figure 4;
Figure 6 is a front view of the connection c _~nent of Figures 4 and 5;
Figure 7 illustrates the flexing capability of the Figure 4 embodiment;
Figure 8 shows in axial section another applicator construction;
Figures 9a and 9b illustrate the flexing capability of the Figure 8 emboA;~nt;
Figures 10 and 11 show the applicator o~
Figure 8 with respective forms of applicator tip element mounted to the flexible connection part;
Figure 12 is an axial section showing yet another applicator ~mhodying the invention; and CA 0224017~ 1998-06-10 W097/21554 PCT~S96119885 Figures 13a and 13(b) illustrate the flexing capa~ility of the application of Figure 12.
The correction fluid applicator shown in Figures l and Z comprises a substantially rigid stem 1 att~ch~ to and projecting axially from the underside of a correction fluid bottle cap 2. At the lower end of the stem i8 a connection part 3 which is formed integrally with the stem.
The connection part includes a waisted section 4 of reduced diameter defining a flexing point about which a lower portion of this part is able to deflect resiliently between a ~o ~1 position axially aligned with the stem (condition (a) in Fig. 2) to a position substantially at 90~ to the stem (condition (c) in Fig.2). Fixed onto the connection part 3 is an application element in the $orm of a moulded tip member 5 of open cell foam which can be any reguired shape, e.g. with a pointed tip or with a flat blade-like edge.
The foam tip member can be secured in any convenient -n"~r, such as by adhesive.
In use, the tip member is dipped into a body of correction fluid and absorbs some of the fluid.
When the tip is applied to and moved across a surface with a natural stroking action, as the stroke progresses the connection part 3 flexes causing the tip member to de~lect progres~ively from the nor~l in line position in accordance with the se~uence (a)-(b)~~c) shown in Figure 2. When the applicator is lifted from the surface at the end of the stroke, the connection part 3 and tip member 5 revert to their in-line positions due to the resilience of the material of the connection part. This resilience also en~ures that the tip member is pressed with an even force against the paper thereby, assisting in delivering fluid ~rom the tip member at a constant rate when the tip m~her is ~troked across a paper surfacQ.
The applicator shown in Figure 3 is largely CA 0224017~ 1998-06-10 Wo97/21554 PCT~S96/19885 the same as that of Figures l and 2 and it differs only in that the connection part is formed as a separate component and fastened to the end of the stem l.
Conveniently the connection part includes a root 6 or peg which is fitted into and secured in a blind bore provided at the end of the stem.
Figures 4-7 show another applicator with a separate connection part fixed to the stem l in the ~ame way as described in ~onn~ction with Figure 3. The connection part 3 has a generally flat blade section 8 around the free end edge of which a pad 9 of open cell foam is wrapped to form an application element. The blade section includes a pair of opposed notches lO in its side edges which define a flexing point at which the section will flex resiliently with respect to the ~tem. Due to the flat shape, the flexure occurs about a pivot axis, like a living hinge, the foam pad 9 being supported against v~.E~t relative to the stOEm in directions other than about the pivot axis. The notches lO also serve to locate and retain a collar or monofilament ll tied around the foam pad to secure it to the connection part. Of course other methods of fixing could be used to secure the foam pad.
In use the applicator of Figs. 4-6 functions in essentially the same way as that of Figs. 1-2, although the applicator in this instance needs to be oriented 80 that the pivotal axis about which flexing can occur is transverse to the direction of displacement of the foam pad application element over the paper surface. At the beg;nn;ng of an application stro~e the foam pad is aligned with the stem as indicated in Fig. 7(a), and at the end of a full stroke it will be at about 90~ to the initial position, as shown in Fig.7 (b).
Figures 8-ll illustrate an applicator in which the resiliently flexible connection part consists of a straight rod 12 of rubber-like material, or CA 02240l7~ l998-06-l0 WO97/21554 PCT~S96/19885 suitably resilient plastics, such as sintered ethylene vinyl acetate. The cross-section o~ the rod is not important and it may be conveniently circular, ~quare or rectan~ul~r. One end o$ the rod acts as a root inserted into a bore $ormed in the end of the rigid stem 1, and staked in position by a pin 13 in~erted transversely through the stem and rod. The projecting portion of the rod is capable of flexing resiliently through about 90~ as depicted in Figs. g(a) and 9(b).
Carried on the projecting portion o$ the rod iR the application element which can be of any convenient $orm such a pad 14 or sock of open cell foam secured on the rod by adhesive or by a mechanical fixing means. The foam application element can be of any desirable shape, such as rounded a8 in Fig. 10 or more pointed as in Fig. 11.
The applicator of Fig~. 12 and 13 is of the same general construction as those Figs. 8-11, but di$~ers in that the application element 15 and the resiliently flexible rod 12 which connects to the stem are made in one piece, such as a sintered ethylene vinyl acetate moulding or casting. Figs. 13 (a) and (b) illustrate the flexibility and indicate that the application element can be deflected to a position approximatQly 90~ to the normal position aligned with stem.
The applicators of Figs. 8-13 are u~ed and operate by the application element flexing in the same way as described above in connection with the earlier embodiments.
Although described in connection with correction fluid application, applicator~ according to the invention can be used for other purposes, e.g.
appl~ing cosmetics or make-up. Providing for re~ilient deflection of the application element allows pressure to be applied without causing the application element to splay open, as occurs with the bristles o$ a brush.

WO97/21554 PCT~S96/19885 Applying a uniform film of $1uid ha~ the further advantage that the drying time is substantially constant for all portion~ of the film. Furth~more, the deflection of the application element can im~rove visibility and hence accuracy in use of the applicator.
