2 Claims.

My invention relates to an interchangeable combined cap and dispenser for jars and the like, adapted to be attachable to an empty jar having viscous contents therein, particularly to cosmetic cold cream jars having an inner tapering Wall portion.

One of the important objects of my invention is in the embodiment of a double cap arrangement, in which the outer plastic member is provided with an inner metallic threaded member that is secured to the top open portion of the jar, after which the outer plastic member may be rotated as desired, to force downwardly a pusher or disk piston member and its paper-like washer contacting the viscous contents Within the jar, for expelling same through a hollow screw stem member onto the top of the outer plastic cap. Single cap members made of plastics generally are affected by changes of temperatures, in which they may crack or split open when secured tightly to the jar, hence the use of an inner metal cap member secured within a rotatable outer plastic cap member.

Another object of my invention is the advantage of my inner metal member, that is adapted to be secured to any type of jar having locking means, because of the low cost of changing the inner cap member to correspond to the particular locking means of any jar as plastic caps would require expensive moulds to make plastic caps to fit onto different types of jars, and therefore, it is believed that my inner low cost metal cap would .be more preferable.

A further object of my invention is that a single cap arrangement may be adopted as a much preferred form, in Which event, this cap would be of plastic or metal, and the tubular stem and the piston member and its paper-like washer, are operated by a knob-like portion fully rotatable on or in the crown portion of the cap secured to the jar.

For further understanding of my cap attach- :ment unit, it is applied to the outside of a container or jar having within suitable viscous contents, such as cold cream for example, having aflixed to it the usual cover, which is removed and discarded, and in place thereof, the inner metal cap member of my double cap attachment unit is then secured to the jar which has a downward tapering bore. Now, by simply turning the outer rotatable cap member associated with my unit, the cold cream will be expelled through an inner tube normally sealed by a cap-stopper. Such expressing is achieved by having a threaded tubular stem member secured as an integral part of the outer or top cap member. The threaded tubular stem member carries a pusher member onto which is placed a paper washer having a yieldable periphery rim portion, so when the latter contacts the inner tapered wall portion of the jar during rotation of the top cap and extended threaded stem which forces the pusher member and paper washer onto the cold cream, the periphery rim portion of the paper Washer is also forced down into the increasingly constricted bore of the jar, and a wiping contact is obtained onto the inner face of the tapered wall portion. In other words, the periphery rim edge of the paper washer will yield under pressure thereby curling or be compressed onto the tapered wall portion, so that all of the cold cream within the jar will be projected and expelled upwardly through the tubular threaded stem member to a desired height above a mound portion of the outer cap member, whereat it is readily scooped off by the ngers of the user, and when jar becomes empty the paper washer will remain in its wedged position at the bottom of the empty jar, and then the combined cap and depressing device is reattached to another full jar of cold cream, previous to which a clean and newly fresh paper-like washer has been attached to the underside of the disk portion of the pusher member, the previous used paperwasher being wedged into the extreme bottom portion of the discarded jar.

Other objects of this invention will appear as the description proceeds in the following speciiication, accompanied by the annexed drawings in which Figure 1 is an exterior elevational View of the interchangeable combined cap and dispenser device of my invention.

Referring .to the `dra-wings, lan outer plastic .cap .member I :is provided `with a top crown portion 2 that may or :may not have .a ibossor mound -portion lil having a ,counterbore portion Il :into which .is .tted tightly .a threaded screw-like Vstem or tubular member 5 provided with .a hollow passage V4i, yall `of which are made of .any suitable plastic, metallic, transparent vor translucent material. tubular member 5 with its stem portion may be formed integral with the outer cap member I, .but is :considered ynot practical.

Under the .outer or .upper .plastic cap meber :I is another or second cap member 1, preferably Vmade of metal, which has a centra-1 opening 28 adapted lto 'be snapped `into a vcircular` groove l.portion :9 of an inner boss portion I 0 A4of the 'outer cap member I, thereby for-ming a combined double -cap arrangement. The li-nner boss por- `tion 4.0 may or may not be provided with -a `recessed or counterbor-ed por-tion -I 5I to receive the collar-'boss portion I2 of a, pusher Vor piston pressure Vdisk member -I3 having pointed projections 13a on the bottom thereof, onto which is mounted and secured a flexible or yielding washer-like ring member I4, for example, made of paper, which may be treated with chemicals to Vmake same liquid proof, or may be untreated, in which event, thin waxed paper washers I4a 'may be added to prevent the -cream soaking into 'the paper-like washer I4.

It is to be noted that the 'periphery edge por- -ftion I5 is crimped -or `formed at I6, see Figures 4 and 9, to allow same to yield in the downward movement in the constricted bore and against the inner taper-ing wall portion IW of `a 'ja-r J, which may have reduced top rim portion, onto which is secured the inner metal cap :member 'l by screw-.like threads, projections or as otherwise desired, .after Athe :cover C, shown in Adotdash lines in Figure 2, has been removed. Y

the illustrative view .of Figure '.2, itis obvious that when .my `cap attachment unit `is being attacked to the jar J, the viscous contents 'VC within the jar, fen-ter the hollow :passage *.6v of the screw-like stem member 25, in which the 4 Viscous contents may rise until it contacts the washerI4, whereby the friction therewith will prevent the washer and pusher member from turning when the outer plastic cap member is slightly turned which rotates the screw-like stem member 5, thereby forcing the pusher member 1.3 and washer Id downwardly against the viscous .contents VC, `which is forced upwardly through the passage 6 and outwardly onto the mound 3, clearly shown in Figure 3.

In event the viscous contents VC within the (j ar .does not i'ill the jar completely, thereby leaving a space under the washer I4 when in its uppermost and normal position as shown in Figure 10, means may be adopted to move the pusher member I3 down until it contacts the viscous contents VC, such as for example, by a projecting tab or lub I6, on the pusher member I3.

When the cap attachment unit AU is not in use .onto jar J, "a sealing cap 20 is placed onto the top boss or mound portion 3 which is slightly tapered, (or may be screw-threaded, if so `-desired) and a plug-like or stopper portion 2I seals the mouth opening 3 of the .discharge passage 6 vwithin the screw stern 5.

The .cap attachment unit AU when attached and secured firmly to the reduced open end portion lvl of the jar J, provides aseal thereat, thereby providing three Vdistinct .sealing means for the jar and the cap attachment unit, the other two sealing means being the yielding periphery rim portion of the washer-disk member I3 under forced pressure .onto the inner tapering wall portion IW of the jar, and the discharge opening cap member 2li with its Aplug or stopper portion 2l into the cream discharge vopening 3 lof vthe cap attachment unit AU.

In Figure 5, an inner metal ferrule screw member 25 may be used in place of the inner metal cap member l, which also allows the outer cap vmember I to freely rotate, similar to the arrangement shown in Figure 3, and by the beaded rim portion BR. of the cap l.

In Figure 6, a single cap member .Ia of any desired material, is shown with a threaded rim TH and a reduced mound portion 3a., onto which is .secured ,a knob 3b of the extended `member sim- Vilar to the threaded stem portion `5 .of Figure 5, which vis locked and secured for example, by a lock washer of vsplit halves .secured in the counterbore portion of the cap member Ia or by a key :pin 5c.

An agitator 2'! may be or may not be attach- :able to and removable from the end portion of Vthe hollow screw-stem 5, thereby Vpreventing .clogging or jamming of the cream in the entrance space ES, `see Figure 3, and assist in keeping this .space passable for the forced cream or viscous contents therethrough. However, other means may be adopted, just so it is .as .effective for the 4same purpose, The washer I4 may or may not be cut as at v21a to allow .same to t onto agi- 'tating member 2t', as the agitator must operate in rotation beneath the washer i4 which is held 'stationary against cream under pressure by the .disk pusher member I3, which is held station- -ary simultaneously .by the pointed .proections 13a, or any other .suitable .means as may be `desired, or they underside of the disk vI 3 may be perfectly smooth .as shown in Figure 4a, or may 4have ya'iile or rough nis'h to grip washer. 'The paper-like washer I4 may not contact the -full underside portion of .the pusher member I3, lmay t like a, ring in the shoulder portion I3c and i3d as shown in Figures 10 and 10a.

In Figure 10 a gasket-ring or resilient pistonring member 30, or this may be the paper-like Washer I3 formed in a ring member, either of which may be tted into the depressed portion 3| of the pusher member I3a, which may be a stamping l3b, such as shown in Figure 10a, the collar portion l2" being threaded to suit.

In Figure 11 an exterior view shows the cap attachment unit AU secured to the jar J when not in use, and Figure 3 shows same in use, with the forced cream projecting above the mound portion 3, whereat the cream is scooped off by the fingers of the user.

In Figure 12 an illustrative view in perspective, clearly shows the cap attachment unit AU being attached to a full jar of cold cream, in which the hollow portion 6 of the screw stem 5 may be thoroughly cleaned as shown, or may still retain cold cream from its previous cold cream jar to which it was attached.

The inner cap member 'l may have a corrugated rim portion 45e, which may be all around as shown, or partially spaced, so in securing the cap to a new full jar, the thin rim portion of the outer cap member I may be squeezed until it contacts the corrugated portions 45o, thereby turning threaded rim of the inner cap member 1 for securing same to the jar J, the cap 'I may or may not be provided with corrugated portions 45d, in full depth or a part thereof.

It is to be understood that similar parts in different views in drawings may have the same numeral primed, and the double threaded tubular stem portion may have standard V-shape threads, and any of the parts hereinbefore de scribed, may be as otherwise desired, and I do not wish to confine myself to the exactness of any part or detail shown in the drawing, and reserve the right to alter and improve same, providing same comes within the scope of the appended claims.

It is to be further understood that the double threaded stem portion 5 in which the square type of threaded and long pitch of threads, en-

ables the user to rotate the free outer cap slightly,

and also provides a neat and safe construction, is easily handled and is safe vin washing and cleaning operations, in which V-pointed threads may cut the ingers or hands. However, the V-pointed threads can be chamfered and smoothed suiiciently to make them safe also. The pitch of the threads is a matter of adoption, but it is believed that much time is saved by the double threads, whereby a slight turn is all that is necessary, especially among theatrical, stage or movie, actors and actresses, this saving of time is of importance.

What I claim as new and desire to secure by Letters Patent of the United States of America, is as follows:

1. A combined cap and dispensing attachment device for jars and the like, and of the character described, comprising an upper cap member provided with a recessed crown portion having a counter-bored portion, a threaded hollow stem member extending therefrom, said recessed crown portion having a hole therethrough, whereat it communicates with the hollow portion of said stem member, a boss portion provided with a circular groove portion, a second cap member provided with a similar recessed crown central opening and a flange rim portion, said central opening of said second cap member secured rotatably in said circular'groove of said boss portion of said outer cap member, a disklike pusher member having a threaded collarboss portion arranged and operative on said threaded hollow stem member, said disk-like pusher member normally positioned within the inner recessed crown portion of said second cap member, with said collar-boss portion extending in said counterbored portion, whereby the ange rim portion of said second cap member is adapted to be attached to a jar having viscous contents therein.

2. A combined cap and dispensing attachment device for jars and the like, and as dened in claim 1, said outer cap member provided with a downwardly lug projection, said disk-like pusher member provided with a upwardly lug projection, when outer cap member is rotated said lug projections are engaged thereby propelling said disk-like pusher member until it contacts said viscous contents, whereat said lug projections become disengaged, whereby said disk-like pusher member is then propelled by said outer cap member and its co-acting threaded hollow stem member.
