l Claims.

This inventionrelateslto applicators; andmore particularly tol applicators such as are; used for dispensing medicaments, jellies, pastes and other substances tolbody'oriices, and the. like.

The structure of;` the instant' invention may be readily disassembled' and reassembled for cleaning and other purposes.

The inventionl is selfcontained, the applicator parts hav-ing interengaging meansto enable them to be assembled and disassembled at the will of the user, in alfacile -andrapid manner.

The foregoing, and other advantageous ob.- j'ects, which will later appear, are accomplished by thestructure' of my invention, of which certain embodiments arel illustrated inr the accompanying drawings. Modificationsand other fo'rmsfy of. thel inventionk will; become readily apparent from` a: consideration of: saidA drawings and the description hereinafter; all. other forms comingwithinthe scopeof the appendedV claims shall be deemedv to be Within the. scope and purviewf of `the invention.

Fig:` 15i a. fragmentary, vertical;l sectional Afr-enr oser-ca (Cl. 12S-261) 2. View thereof, showing t-lre interenga'gingv means of' the plunger head-"andi ringl engaged.

The tubev andi-other partsof the applicator may be madev of' anyr suitable or convenient' material, as, forexample, a transparent or translucent thermoplastic or ther-mosettingf material, preferably of such'design as toprovide for view ing the passage'of material-l through the. applicator tube.

Pursuant to theA invention'. herein` described, the applicator tube-isprovide'd with a collar fixed to the upper end'thereofandy having an aperture in which the plunger.' may' be fully reci1: 'rocat'ed,v saidfaperture"beingc ofy suflic'ient diameter' tol permit withdrawal theretl'irfo'ugh of the. plunger and thel enlarged. piston-1 end thereof; for cleaning and other purposes. The upper end of the collar is closed by an open ring, the: openingof the ring being suiilcientf` tof provide for` free' reciprocation of the plunger thereinibutbeing'of lessdiameter than the piston4 soasto normallypreclude complete Withdrawal' `of' the. plunger. The' closure ring and collarare'y provided. with complementary means to normally seat thering in the collar.

As shown inlig.A l, the.' applicator. tube Ill is provided withanfinternallythreaded cap I I iixed to the lower endv thereof, whereby the same may be secured t0'thescollapsibletube I2 (Fig. 9) to initially'll thei. tube Iuwith the material to be dispensed.

The assembledy applicator of my invention comprises the'partslshownin Figs. 1 and 2, the plunger I3 being positioned in. the tube' I0 and being' adapted to" betreciprocated" therein. The closure'ring I6' and collar I5have complementary means (such asthreadedr portions. as shown.) to seat the ring in: the'. collar. The ring I (i` constitutes a guide' for the plunger I3; The opening d' of the ringv i6 is (Fig 7)A` greater than the diameter of theplunger I3. butl less than the diameterD of thevpiston.: I'4 onv the lower end of plunger I 3, the piston` Iffbeing. of slightly smaller diameter than thefinternal diameter d of tube I0. The plunger I3 is provided at its upper endiwith a key head. member.: Iz-T. Thevlatter'is provided withy a depen'dingxiiange or circumferential rim 2U. The key headzmemberA I1 and closure ring. I6 areprovidedv with:` any desired or convenient interengaging complementary means'. I8I9 for rotary movement-1 of the head and ringk simultaneously, such .as key members or vanes I8 on the. head member: receivedv within slots or key- Ways I9` of theclosurering I6', orviceversa. By virtue of said complementary keyingy means, it will be apparentl (see-'Fig '1)V that by registering the. complementary..l keying. means` I8--I'9 `and i rov clockwise direction, indicated by arrow B in Fig.

8, said closure ring IB may be disengaged from the collar I5, so that the plunger I3 and its associated parts (see Fig. 2) may be withdrawn from the tube I0, to provide for complete cleaning, etc., of said parts. Thereafter, the applicator may be reassembled as above described.

In Figs. 10-15, there are illustrated other forms of the invention.

In the form shown in Fig. 10, the collar 25 secured to the upper end of the applicator tube 26 is externally threaded as at 2l, to be threadedly engaged by the complementarily threaded portion 28 of the closure ring 29. The opening 39 of the ring 29 is of greater` diameter than the plunger 3| but is of less diameter than that of the piston secured to the lower end thereof.

It will be understood that the piston I4 of Fig. 2 is secured to the lower end of the plunger I3. In the various forms illustrated in Figs. 10-15; a showing thereof has been omitted in the last mentioned gures to avoid needless duplication in the drawings.

The plunger 3I has secured to the upper end thereof a head 32, said head and ring being provided with complementary interengaging keying means 33--34 which are adapted to seat the ring 29 on the collar 25 when the head 32 is rotated in one direction, and to provide for disengagement thereof when the head is rotated in an opposite direction.

In form shown in Fig. 1l, the applicator tube 35 has a collar 36 secured to the upper end thereof, said collar having an aperture 36a and an internally stepped portion 3l'. The ring 39 is provided with a complementarily stepped portion 3B adapted to frictionally nt within the stepped recess 3l of the collar 35 to normally frictionally seat said ring in the collar. The ring is provided with rim :lil projecting beyond the circumference of the collar 3G. The rim i0 may thus be readily grasped to forcefully remove the ring from its seat in the collar, when so desired, to provide for complete withdrawal of the plunger from the tube. The plunger 4I is provided with a head 42 for facility of operation of the plunger.

In the form shown in Figs. 12 and 13, the tube 43 has a collar 44 secured to the upper end thereof, said collar` having a stepped, recessed, portion in which the complementary portion 46 .of the ring I? may be frictionally seated. The jplunger 23 has secured to the upper end thereof :the head 43. The ring 47 and head 48 are provided with complementary interengaging means A.to permit the withdrawal of the ring Elphysically from the seat of the collar. Said keying means may comprise a bayonet-'slot arrangement 49-50.

In the form shown in Figs. 14 and 15, the ring YI is seated in the collar 52, and the head 53 is secured to the upper end of the plunger 54, the ring and collar being provided with complementary interengaging means comprising bayonet-slot members 55-56; in the form shown in Figs. 14 and l5, the pins 56 are secured to the ring 5I and the slots 55 are disposed in the head member, whereas, in Fig. 12, the reverse arrangement is shown.

The drawings show (Figs. 1-9) the cap II and collar I5 as separate units secured to tube I0, but

they may be molded with the tube I 0 so as to dene therewith a single article of the combined general outline of the three separate parts (tube I0, cap II and collar I5). Similarly, the plunger I3, key head I'1 and piston I4 may be molded as a single article, if so desired, or may be formed as shown in the drawings of the three separate parts secured together in any desired or convenient manner. The corresponding parts, shown in Figs. 10-l5, may be similarly formed.

It is noted that the collar I5 is xed to the tube Ill permanently. Likewise the collars 25, 36, 44 and 52 are permanently fixed to the tubes 26, 35, 43 and 51, respectively. All of the rings I6, 29, 38, 45 and 5I are detachable from their associated collars.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
