Other objects of the invention wil1 in part beobvious and will in part appear hereinafter.
The invention accordiri gly comprises the several steps and the relation and order of one or more of such steps with respect to each of the others, and the article possessing the features, properties, and the relation of elements, which are exemplified in the following detailed disclosure, and the scope of the application of which will be indicated in the claims.
For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:
Fig. 1 is a perspective view, partly sectional, of a face powder box with its cover and mustrating an embodiment of the invention;
Fig. 2 is a vertical section through the box of Fig. 1;
Fig. 3 is an enlarged vertical section of a portion of the box, the dotted fines illustrating the drum before being seated in position in the base of the box;

Fig. 5 is a plan view illustrating a ring made of a coiled strip of paper and which may be utilized either in the base or in the drum, the paper strip being thicker than that which may be employedr and Fig. 6 is a detailed sectiona1 view through one side of the box, somewhat enlarged over Fig. 2.
Referring now more specifically to the drawing, the' base of the box is indicated at A; the
2. Similarly, the cover B has a head 3, and a depending flange or ring t and the head 3 may be domed as illustrated. The drum provides et con tainer for reception of face p'owder and has a flange or ring 5 and an overlying head 6. In the present invention the head 6 is preferably made of a readilyirangible sheet material such as tissue paper or any of the well known thin, translucent sheet materials. A sufficiently large sheet is selected and its margin or edge is folded onto the outside face of the drum-ring or flange 5, the fold being secured by an overlying strip of thin cover pape! i extending continuousiy around the drum ring 5 and pasted to saidring. The cover strip not only secures the fold of the drum head 6; it also covers any sma1l wrinkles in the fold and provides. a relatively smooth, unwrinkled outer side face of the drum flange or ring 5. For convenience of the powder maker, the base A, cover B and drum C are provided as separate units. The drum C Cil is open at its end opposite or remote from the head 6, and the powder maker places it with its open end up so it may easily befilled With the powde'r. Thereupon after filling, the drum may be inserted in the base A, the flange or ring 2 becoming an outer ring and the danse or ring 5 becoming an inner ring. In this manner the base A not only forms a closure for the filling opening of the powder containing drum C, but it also forms a. receptacle and housing in which the drum is received. For finishing the base flange 2, and securing it to the'head l, a thin strip of ornamental paper or other material 8 may be wound onto the flange 2 and will be folded over the open edge of this flange and around onto the head I, and adhesively sec11red inside and outside the base A. In like manner a finishing strip 9 ma be aflixed to the cover B, and entirely over the head 3;
The present invention is of advantage in hand made boxes inasmuch as among other factors, it promotes quick assembly of the parts and the making ci a non-sifting face powder box, but it possesses very important advantages when utilized in paper boxes the parts 01. which are made by automatic machinery operating at high speed. One of the most important objects sought for in a face powder box is that it shall not siit; that it shall be siftless", meaning that the powdered contents shall be retaihed in the box and not sift out through its joints. to avoid sifting, the diameters of the drum flange 5 and the base fiange 2 have heretofore been et relative siz to obtain as tight a. fit as possible consistent with the requirement that one must be inserted in the other in telescopic relation. The result has been that in many cases the insertion may not be eiected at all or only with the greatest care, thus leading to great loss of time and waste of materials, and increasing production'costs and slowing down output. The high speed machines are thus not effective to produce merchantable boxes in the qnantities for which they are designed. They may run at high speed, but much of the product has to be rejected. Also, various supplemental operations at substantial cost have been resor'ted. to, none 01 which has been satisfacto'ry, especially in making a satisfactory face powder box capable of being marketed at low cost, as for instance required in the ten-cent stores.
Dependence upon the fit of the drum flange and the base flange for tightness has been entirely unsatisiactory. 'supplemental operations of the past have been equally unsatisfactory in preventing or minimizing sifting and have but added to operations and to cost.
An important aspect of the present invention concerns the relative diameters of the inner and outer rings or w.lls provided for the base and drum respectively.
An important related feature of the present invention resides in providing an inner drum ring or fiange of appreciably smaller enter diameter than the internal diameter' of the outer base-ring, thus allowing a loose fit between the rings notwithstanding variation of moisture coritent or thickness of stock material, so that free entry of one ring into the other is readily' permitted under al] conditions, a space beingthus always provided between the two rings in their telescopic relation to each other. The importance of this will become mainifest from the following considerationst In modem. high' speed, automatic box ma,-
As tending chines these rings are formed by coilingor wind ing relatively stifl, thin paper stock on rotating mandrels having fixed diameters. It has been the common practice to depend upon the closeness or tightness of the fit of the outer diameter of the drum ring, or flange, against the inner diameter of the base ring, or flange, to hold the powder in the box and to prevent sifting, i. e., escape of the finely divided particles out of the drum, and accumulation of substantial amounts in loose condition, on the top of the drum head and beneath the cover, especiallv before the cover is removed. It is a diflerence in diameter of but a few thousandths of an inch between the fit of the rings or fianges on each other that may result in suiflcient looseness to sift powder or one that is so tight that these rings"cannot be made to telescope. Drum rings or fianges are commonly made of tWo, three or more ply light weight paper, and while on the whole they are relatively stifl, they may have some flexibility, dependent on the paper; stock and the number of plies employed. As has been before explained, the margin of the head 6 is folded down and a cover strip 1 may be applied. Accordingly any predetermined outside diameter of the drum ring is dependent on several factors including the thickness of the paper stock and of the glue which may be employed to hold the plies together and to secure the cover strip. Assuming it to be the practice to purchase nine and on-half point card-middling stock from which to coil a four-ply drum ring but such stock averages ten and one-half points in thickness instead of nine and one-half points, eight thousandths 01. an inch 'will be added to the outer diameter of the drum. -And it is not uncommon to flnd even more variation, eight point to eleven point, aflecting the outer diameter of the drum ring in paper stock of this small caliper. Not only is there this 1mavoidable variation in thickness or caliper of the paper stock which will result in a non-telescoping drum-ring. There are also variations in thickness due to moisture content of the stock, its thickness being one caliper when made and a diflernt thickness when assembled drum to base. By providing the drum-ring of appreciably smaller outer diameter thari the internal diameter of the base ring and having the loose fit as hereinbeiore stated, the objections dependent on variations et stock-thickness are very substantially avoided and the production of siftless boxes at high speed on automatic machinery is greatly promoted, and this'is especially so when taken in conjunction with the feature of the invention which arrests the escape of powder notwithstanding the rings are of appreciably difierent'diameter as aforesaid. As illustrated in the drawing, the drum .ring 5 is formed 'of relatively stifl thin paper stock coiled in a plurality of plies into ring formation as shown in Fig. 5. Also it is to be undel5t00d that the ring or flange of the base niay be constructed of a simflarly coiled paper strip.
Another important aspect of the invention relates to adjusting or compensating for the loosewhether due'to moisture or to unavoidable variation in original stock material) and nvertheless to promote the anti-sift features of the powder box. To this end a means is provided 75 a tight fit in the joint between the base and drum. Initially this means may be mounted either on the. base or on the drum, but it is preferably initially mounted on the drum, It includes plastic, jbint-packing or caulking material l0 which is cooperable to join the fianges or rings of the base and the drum together and, in the embodimentfllustrated lies between said rings and is in the.form of a continuous circumferential bead or ring around the drum ring 5. It is of narrow width relative to that of the box rings and is spaced apart from the end 2 of the drum. It is preferably located close to the head 6 of,the drum and overlies the fold thereof. It adds to thestiffness of the drum space between said rings when the rings a1;e'
loosely to interfit.
and hence tends to hold the head 6 tant. When initially on the outer face of the separate drum flange or the inner face of the seprate base fiange, it protrudes thereirom and its protruding portion 15 curved or convexed outwardly in cross-section, as clearly seen in Figs. 3 and 4, and forms a relatively narfow strip pr bead projecting laterally of the fiange.
The material of the ring or bead Il) is relatively soit and readily ,shearable and compressible and it is adapted to be altered in thickness by contacting With the base flange or ring under the force of seating the drum ring in its operable position in the base ring or fiange. In the 'operation of telescoping the flanges 2 and 5, the
will cause said bead tightly to pack en caulk the space between said flanges.
A suitable plastic material for the ring il] is some species of solid wax or wax like substance, as blended wax Preferably the ring li) is. bonded to the drumor base, whichever is the initial carrier, in a melted state. Under mild heat it may be bonded to the other ring after telescopic insertion in the other ring. The ring ll0 forms an exterior layer on the box part.
In some instances it is desirable to utilize for the ring in a species of plastic, as wax, towhich due to its tackiness particles of the face powder will adhere, thus anchoring the powderparticles to the wax substance, and to the paperthese particles tending to block any fine interstices in the wax pacl ing and forming a. packing of po'wdered material.
It is to be understood that either the base or drum having the wax or plastic ring m. mounted thereon is utilizable alone as a. separate article of manufacture for any convenient use. In carrying out the method, the base flanges or rings are formed separately from the drum fianges or rings, and of relative size After the paper rings are made the interfitting face of one ring is provided with a plastic shoulder or conforming ring,
as the packin ring Il) otwax or other plastic material which is thicker than the maximum in intrfittingelation. This-ma be' done by directirig onto the drum while on its mandrel a stream of the melted, plastic material. This also bonds the plastic to the drum. Thereafter one ring, atter 'being filled with powder, is pressed into the other and by the pressing or driving operation the conforming ring or shoul-' der is dfiven into position tightly naclflng the tion et the plastic is to interrupt and forma non-sifting powder-barrier in the joint between the rings. It fills the space between the rings and also will mold itself into all irregularities of the space, as for instance formed by the ends or edges of the cover-paper, the folded margin of the head 6, and other irregularites. The plastic ring l0 is of a substance relatively soit and solid at room temperature, as for instance some species of wax, and the melting point of this substance is considerably lower than the point of infiammability or charring of the paper so that the substance may be bonded to the paper by the application of heat without injur ing the paper. Also the substance may have some degree of viscidity or tackiness in the solid state so that particles of powder may adhere to the=- packing.
It is to be understood that among the sub stances of which the ring I!) may be made are the various waxes, such as parafiine, beeswax, halowax, carnauba, Spermaceti, cerese or combinations of these waxes, or mixture of chlorodiphenyl and sulphur, the former comprising the larger percentage of the mixture. Bitumens or resinous materials might be used, or combination of bitumens and resins.
In bases having non-fiaring open ends, the diameter of the plastic ring I0 on the drum ring should be larger than that of the open end of the base ring so as to either be compressed and slide over the edge of said open end or to have a portion sheared off from the plastic ring in the operation of telscoping the two rings. In either case tight interfitting of the ring I0 in the joint 13 effected.
It is to be understood that the boxes need not be round as illustrated, but may be aval or polygonal or of any shape appiopriate for embodying the invention. Accordingly it is to be understood that the terms ring, flange, etc; herein employed cover and comprehend similar walls for the box parts whether they are circular, oval, square, hexagonal, orother shapes. 4 It is to be understood that the packing or caulking bead l0 may in some instances be applied to the base ange instead of to the drum flange, or each of these parts may have an individual bead. The bead applied to the drum is more practical however and is to be preferred. It is also to be understood that, whereas a Coi1ed or multi-ply flange is illustrated the invenmation. Thin paper stock 13 preferred for the materi.l otthe flanges, but it is to be understood that the invention is available for boxes or box-flanges made of. other materials, a's pasteboard, card,-mid dle stock, and thelile. Also in some instances the conforming ring or bead il) 1s colored-in contrast to the color of the fiange to which it is applied, thus enabling its structure and arrangement to be more readfly observed, and, any defects noted and remedied.
It is-alsO to 'be understood that, in some aspects of the invention, the shapeoi the caulking or packing may vary fr.om continuous ring form, an important feature being to close the joint between the base and drum regardless oi the shape of packing.required to do so.
