DMarch 26, 1946.V F. B. BAKER A APPLICA-TOR FOR ADHESIVES Fii'ed March 19, 1943 spects `over my prior applicator. proved form of applicator `I use a rigid wooden Patented Mar. 26, 1946 yUNITED STATES PATENT, office APPLIoA'roR Fon Annnslvns PFranklinTB.lBakerfUhicagoJll. Application March .19, 1943,seriaifNauva7o-7 (Cifra-#14013) 2'Clams.
This invention relates to improvements in `adhesive applicators.
Various distinctly dilferenttypes of applicators `are required for many different conditions` of use.
.Among them are applicators which can be kept immersed in a pasteor mucilagejar between ,pe-
.riods of use,andit is this type with-which .this
invention is concerned. In the applicator which .Ihave .heretofore devised, a rigid wooden stem is securedby a tack to the inner surface ofabottle cap and a thinsheet of iiexible rubber isfsecured to the-lower'end of the wooden stem to` serve as the aspreaderffor the adhesive.
vIhave'now .devised a new form of applicator which Ico-nsider an improvement in certain re- .In this imstem firmly secured to the bottle `capyas in my iprior invention, but the adhesive spreader is supported on the wooden stem by means of a rubber Vboot having the spreader formed integrally'therewithor attached thereto. The boot not only actingwith the adhesivetofgive it an ,undesirable odor or color, orwhich might causel objectionable reactions on the wood itself.
In accordance with this invention, I employ a wooden xste'm.A having a squared upper end attached to the inside surface of the cap by an ordinary flat-headed tack, and over this stem I draw a moulded rubber boot having a flexible spreader at its lower end. The boot extends upwardly above the level of the adhesive to the inner surface of the cap and hence no contact between the wooden stem and adhesive can take place. The stem of this applicator is rigid and only the flexible spreader at the lower end is deiiected when the user is holding the applicator by means of the cap. At the same time, the simple, inexpensive and wholly satisfactory method of attaching the stem to the lcap is made possible by the use of a wooden stem inside of the rubber boot. The visible portion of the applicator member being entirely of rubberythe appearance of the device is also enhanced thereby.
In this form of applicator the bottle cap may be used as the handle of the device and a rigid wooden stem enables the user to direct the movements of the applicator very accurately in the area in which the adhesive is to be applied.
The attainment4 of these advantages in this new -form cof applicator, as well as .i other advantages,
comprise therobiects .of .this invention.
:Another Afaidvantagr-z of `:this 4new applicatorz reesides .-.in the .fact 'that I :am able .to :produce ua .competely r'satisfactory l; applicator at extremely low cost .and thus make 'its` advantages available tor-the public 4at-:aapricelwithingthe reach of even thcse with whom f thrift :is a .matter of necessity :instead .of choice.
.Thezaccompanyingdrawing .shows a ,preferred zforin .of .the dnventionwhich :will .serve :to illustrate :the: manner .inzwhichthe invention maybe constructed and used.
Referring nowtothedrawing: Fig. .1. is aLcentralaverticahsectional view` show- ,fingrthe applicator attached toa cap/and posi- .tioned mits-normal relation ,to an adhesive bottle.
Fig.. 211s .an4 elevation4 Vof the cap and applicantorrfrom;appositionatA right angles to the position :of :E ig.;1.
:Fig .-3 ris an elevation showing `the applicator infuse.
iReferrng .further topthe drawing, the applica- `tor consists .of1arrigidwoodenstem l Vhaving its rupper end=cut=.off :squarezand held :snugly against -therusualipaperliner 2.of.the cap 3 by means cfa Afiat-headeditackf-llk driven v through the cap. `The rubber portion of the device consists of the-boot -15snuglysurroundingthestem and held thereon :byifagsnugrt `the dowerziend :of the device being .f moulded ato i form :a i fin f6 which merges into the .moulded-boetes' shown inthe drawing.
This moulded product does not require the `use of stock made wholly of new rubber. Hence,
. through the use of some scrap, the cost of the rubber portion of the device is kept low. Yet, because of the rigid wooden stem, its rigid attachment to the cap, and the moulded relationship between the n and the boot, the user is able to maintain accurate control over the manipulation of the iin. This may be contrasted with the difficulties which would be encountered through the use of a solid moulded stem and applicator, it being obvious that if the wooden stem were supplanted by a wholly moulded rubber stem the whole device would have a exibility and snap which would render it too diflicult for one to use accurately. Thus, by providing an applicator capable of accurate control the user will be able to apply a uniform downward pressure and will be able to apply accurately a lm of desired thickness.
In order to attain the flrmest control over the n at the lower end of the rubber boot I so mould the interior of the boot and shape the exterior of the stem that they t together snugly at the lower end of the stem. As shown, the lower end of the stem may be provided with an inwardly tapered surface 'I and a squared lower end 8, both of which snugly t the bottom recess in the boot. The ribs 9 and Il extend upwardly from the n and, merging into the body of the boot, cooperate with the stem in assuring firm control over the spreading n. Hence, the user may accurately control both the direction and uniformity of the spreading of the film of adhesive. 1
In view of the fact that when the device is in use it will often be rested temporarily bottom side draw the boot snugly up against the liner 2 in orfder that the adhesive may not contact the wooden stem, even to a limited extent. Should the applil cator be left out of the bottle inadvertently and adhesive accumulate and dry thereon, the continuous rubber boot makes it easy for the dried adhesive Ato be scraped or washed oli.
Of course, in using the term rubber I mean to include not only the rubber of nature, but also the synthetic rubber substitutes which have recently' become commercially available.
It-will be further noted that not only does this present invention make available the advantages of the rigid wooden stem which can be cheaply secured to the bottle cap, but no special treatment or selection of the wood is required, which I find is of substantial advantage in these days when imperfectly dried or weathered Wood stock is the most commonly available supply,
While my applicator is especially adapted to the spreading of semi-uid and liquid adhesive, it may be employed for the spreading of paste adhesives, and if desired, for the spreading of other materials. Also the shape of the applicator at the bottom oi the stem may be modied and sive.
.In my prior applicationV Serial No. 271,054, illed May 1, 1939 now Patent 2,291,676 dated Aug. 4, 1942, I have shown an applicator which includes the bottle cap with wooden stem attached thereto. i
It should be understood, therefore, that this invention is susceptible of considerable variation without departing from the spirit of the invention as defined in the following claims.
Having shown and described my invention, I claim:
1. In combination, an. adhesive container, a flat-topped cover member therefor, cooperating means on the container and cover for sealing the container by means of the'cover, a rigid wooden stem having its upper endsquared and extending perpendicularly from the underside of the cover member into proximity with the bottom of the container, a flat-headed nail piercing the cover member Yand the squared end of said stem to secure the latter rmly against the cover, and a rub- V,ber boot snugly surrounding the entire length of Yflat-toppto'l cover member therefor, cooperating means on the container and cover for sealing the container by means of the cover, a relatively thick rigid wooden stem having 'its upper end squared Yand extending perpendicularly from the underside of the -cover member into proximity withv the bottom of the container, a flat-headed nail piercing the cover member and the squared end of said stem to secure the latter firmly against the cover, and a moulded rubber element having a relatively thin-walled hollow boot portion snugly surrounding the stem from the underside of the cover toits lower end and having a portion taper- -ing abruptly immediately below the lower end of the stem tov form a thin flexible iin extending to the bottom of the container for spreading adhesive, the lowermostrportion of the stem being reduced Yin Vdiameter to extend snugly into the tapered portion of the rubber element, the cover when removed serving as the gripping means for the adhesive spreader, and when inverted to stand on its top, serving to hold the spreader in a substantially erect balanced position.
