for example as face creams, and in-particular to -adevice in the natureof a compactv which'may be readily and safely carried -in pocketboo-ks,

handbags, toilet kits, and -the like.

A general object of the invention is to provide an attractive article of the nature described comprising a cap section vhaving a dispensing open-r ing and a base-'section Vboth sections lincluding cooperating elements for expelling avcreamy substance through the dispensingopening when one While devices of this general nature have-been heretofore proposed;nevertheless, they have not-come into general use because they 'frequently leak or the parts accidentally become separated to spill or expose vthe contents.

Accordingly, one of the objects' of -theinvention is -to provide a container construction which lends itself to convenient manufacturing practices, and includes mating sections having cooperating means for-being interlocked by mere assembly and partial rotation,'as well aseffective vmeans-for sealing the sections after they areonce assembled and relativelyV rotated-to compress and expel the' contents. y

Another'object is to provide simple and reliable means-for locking-thesections against being returned to their voriginal point of assembly so that they cannotcome apartor be separated'for reuing.

A further object is 'to provide a construction which includes a 'minimum `numberA of parts thereby-making a dispenser which is' economical to' manufacture and Vreliable in use.

vWith the above and other objects in view which will more readily appear as the nature of theinvention is better understood, the same consists in the novel construction, combination, and arrangement of parts, hereinafter more fully described, illustrated and claimed.

A preferred and practical `vnenribodiment of the invention is shown in the accompanying `drawings, in which: Y

' Similar reference characters designate-corresponding parts throughout the several figures of the drawing.

Referring rst tothe embodiment-of the invention shown in Figures 1 to 6,'inclusive, itwill be observed that the same vessentially includes in its organization a cap section A anda base-section B, respectively including sidewalls I and 2 adapted to be interiitted in telescopic relation,

and each being provided externally with 'indexing

ribs

3 and 4 or theirequivalent to facilitate initial assembly and subsequently serve as a signal to indicate the lcontents remaining in the containerafteruse-has once been started. The said indexing elements are alined-to eiiectinitial assembly and after partial rotation of the sections never returnvto this relation because of locking means hereinafter described.

VThe cap'section A is provided'with a dispensing opening or hole 5 radially alined with the indexing element 3 and located in a finger-receiving depression or well 6. 'I he under face of the cover A'isalsofprovided with a downwardly projecting pin 'I which is angularly off-set vwith respect'to the hole E as shown in Figures 2 and 3 and intended to engage with the hook portion '8 of a radially disposed piston vane 9v which is formed at its inner end with an eye lil for fitting over` a post I l axially carried bythe interioriace of the base 2. The vane`-9 therefore,lcan rotate relative to the base. Said base B is'also provided with anvintegral radiallydisposed abutment l2 in the form' of a wall which, like thevpiston vane 9, is coextensive in height with-the space. between the inner surfaces of vthe Ncap and base. It will also be noted that the length of the vanev Qiand the abutment I2 are 'substantially the same so that when considered'in connection with the post Il, completely span the radial distance between the p-ost and interior face of the side walls l and 2 of the cap and base. When the pin 1 is engaged with the hook 8 ofthe'vane it will be apparent that relative rotation ofthe cap Ayto the base B will'cause movement of the vane "9 with're'spect to theabutment I2 so that 'the 'material M (Figures 4 kand 6) will be expelled through the discharge opening or hole 5 into the well 6 of the cap as indicated at M' in Figure 1. The hole 5 and pin l being in angular relationship, and the hole 5 being disposed relativelyin advance of the pin when the pin 'I is engaged with the vane 9, the latter will, of course, when moved by the pin, cause the material in front thereof to pass through the opening 5 since the material M is trapped in the space between the cap and base against the abutment wall I2.

Referring now more particularly to the means of holding the sections A and B together for rotary movement as well as against separation, it may be first noted that the vane 9 preferably carries a locking element I3 in the form of a light leaf spring which is secured at one end to the related face of the vane 9 while its opposite yielding endengages the inner face of the side wall 2 of the container. This spring 1.?, is intended to cooperate with a locking element Ill in the inner face of the side wall 2, and which, in the example shown, is in the form of a notch formed in the side wall to provide a locking shoulder I5. Obviously, however, instead of making the locking element in the form of a notch depressed into the side wall of the base, it may be in the form of a raised tooth with the same general locking effect.

The inner face of the side wall I of the cap A is provided with the diametrically disposed pairs of ribs I6 and II. These ribs are intended to pass through corresponding pairs of notches Ilia and I'Ia in the upper flange portion I8 of the base, said flange portion I8 havingits outer face provided with an annular recess or channel I9 whose upper side wall constitutes an abutment or track against which the pairs of ribs I6 and I'I bear when the sections A and B are rotated relative to i each other.

As previously indicated, the ribs I6 and I'I which cooperate with the notches Ia and Ila on the base are so related to the indicator ribs 3 and i that, when said ribs are in vertical alinement as shown by the dotted line and solid line positions of 3 and 4, respectively, in Figure 1, the ribs I5 can readily enter their related notches Ia in the base. Likewise, when the sections A and B are thus assembled the pin I engages the hook 8 of the vane 9. Upon moving the cap A in the direction of the arrow shown in Figure 1, the

said sections A and B not only become interlocked for further rotary movement to performthe operation of expelling the contents with the aid of the elements 9 and I2; but, also, the spring locking element I3 is moved sufficiently so that it passes beyond the locking element I4. Once the sections A and B are initially rotated relative to each other, continued rotary movement between the same is possible until the contents of the dispenser have been exhausted. Of course it is possible to rotate the elements A and B so that the vane 9 may idly move back substantially to its original position. However, due to the spring leaf I3 and locking element I4, it will be impossible to bring the ribs I6 and I'I back into registering relation with notches Ia and I'la. Thus, after the parts have been once assembled and a portion of the expelling movement of the vane has taken place, it will be impossible for the sections to be subsequently separated yfor the purpose of effecting a rell of the material.

Another distinctive feature of the construction shown in Figures 1 to 6 is that the cap A and base B are provided with suitable sealing means to prevent the escape of the paste or cream un- 4 der pressure. In the example shown this sealing means preferably consists of an annular collar 20 on the inner face of the cap and spaced inwardly from the side wall of said cap so as to lit in a complementary recess 2| in the flange I8 of the side wall 2 of the base.

In the construction shown in Figures 1 to 6 inclusive, the sections A and B having the characteristics described are preferably made from plastic material lso that they can both be readily made by a convenient stamping, molding, or-' pressing operation. The parts A and B together with the piston vane 9 constitute all of the movable parts of the device. Thus, the simplicity of the invention from the standpoint of manufacture and use becomes apparent.

Figure 6a illustrates a modification of the invention above described wherein the piston vane 9a is made integral with the cap section A, and the abutment I2a is likewise made integral with the base section B. VIt Will also be observedthat the post I la and abutment I2a may be integrally formed or connected so that the piston vane A9a carried (by the cap section A may exert adequate pushing force against the contents of the container with respect to the abutment and post. In this form of thefinvention all of the means for interlocking the cap and base previously described are adhered to. The difference between the construction shown in Figure 6a and that shown in Figure 6 is that'the movable vane 9 of the latter gure is made integral with the cap section thereby eliminating the metallic vane as a separate element, and likewise, the locking means I3, I4. I5 of Figure-6 is omitted from the construction shown in Figure 6a.

A modication of the invention is shown in Figure 7 wherein the device may be made of transparent plastic material and cap section A and the base section B have their side walls I b and 2b telescopically intertted, while the base section B is interiorly provided with an integral abutment wall I 2b and the cap section A has integrally formed therewith the piston vane element 9b. In this form of the invention the cap section A is formed with a dispensing or discharge hole 5a, and the piston vane 9a as well as the abutment wall |2b terminate at their inner ends at a point short of a central pivot element 22 for pivotally connecting the sections together. This pivot element may assume various forms but preferably consists of a tubular shell having a head portion at one end for engaging the outer face of one of the sections while its hollow interior is threaded to receive a cap screw 23 whose head engages the outer face of the base. Thus, the pivot 22 serves as a fastening for holding the sections Aand B against accidental separation. In this arrangement the base section B would be lled with cream .or paste and the piston vane 9b and abutment wall I2b assembled in juxtaposed relation so that, as relative movement occurs between the sections on the element 22 as an axis, the movement of the -vane relative to the abutment will expel the material through the discharge opening 5a. In this form the inter-engaging means on the cap and base as per Figures.A 1 to 6 linclusive is unnecessary because of the fastening 22. f

From the foregoing it will be apparent that the invention provides a container for creamy or pasty material from which the same may be dispensed inn the form of a cylindrical ribbon through the cap section, as desired, thereby making it possible readily lto obtain Yasmall amount of the material in a convenient way, while at the same time preserving the remaining contents for future use.

Without further description it is thought that the advantages of the invention will be readily understood by those skilled in the art and will, of course, be apparent that changes can be resorted to within the scope of the appended claims.
