Application led March 10, 1927. Serial No. 174,2554
Theinventi'on relates to improvements in boxes whose primary use is for packaging face powder, and such invention deals with a known type of box, which embodies an inner container which is filled with they owder and is then housed within co-opera le top and bottom sections of the box. Inner vcontainers -of this character are commonly formed with a bottom of paper and cardboard and are provided with a top having a4 comparatively large opening through which the container 4may b-e filled with powder. Aftery this filling operation, the bottomsection of the box is inverted and applied Vto what is then the upper portion of the lled container, the two being I, glued together.
p Then, when the article as so far completed is inverted, the 'top section of the box is applied. In this condition, the box of powder is marketed, and upon removing the top section of lthe box,lthe paper and cardboard which previously formed the bottom of the inner container, areaccessible, so that they, can be removed to give .access to thepowder. Boxes of the type above defined, have a very extensive use and are very desirable, but they are rather expensive/to manufacture and quite an amount o f material yis necessarily cut out and wasted. Moreover, dierent purchasers of these boxes from the factory, require them in dierent sizes and with different sized openings in the tops of the inner containers and hence, a number of expensive dies must bekept on hand, to form these openings and toI otherwise cu't the blanks fromwhichthe. inner container is constructed.
Then too, in forming the side and end walls and the top of the inner container,it is customary to make use of a single cardboard blank, with the above mentioned opening cut from its central portion and with right angular notches cut in'its corner portions, the parts of the blank between the notches being bent to form the side and end 'walls of the container. Thismanner of construction wastes the material cut from the corners of the blank and that cut from its central por. tion to form the opening. Moreover, when the container embodies these `details of construction, it is prone to leak at the corners, I permitting the powder to sift out.
Itis theprinoipal object of the present inventionto providea new andimpro-ved construction for therinner container, 'which is such as to minimize loss pf material'bv cutting, does not require special dies in order to Aform the filling opening in the top of the container, readily permits of assemblage by machine operations, and will be proof against leakage. i
Vith the foregoing in view, the invention resides in t-he novel subject matter hereinafter described andclaimed, the description being supplemented by the accompanying drawing.
Fig. 1 is a disassembled perspective view of the several parts from which the inner containeris constructed.
Fig. 2 is a perspective view of the inner container completely assembled.
Fig. 3 is a vertical sectional View on line 3-3 of Fig. 2.
Fig. 4 is a vertical sectional view through a complete box embodying my improvements.
Fig. 5 is an elevation of the strip from which the outer frame of the inner container and top-forming flaps for said container, are formed.
In the drawing above briefly described, the numeral 6 designates an inner rectangular frame preferably bent from a'single strip of cardboard to form o posed side and end walls 7 and 8, the ends of the strip being secured together by thinning one of them and gluing litto the other strip vend, as indicated at 9.
By forming the frame 6in this manner, there is no danger of powder leakage at the corners thereof and its construction will also be simple, easy and inexpensive.
Preferably, a piece of cardboard 10 rests against the lower edge of the frame 6 to assist in forming a strong bottomtherefor, and a Y sheet of paper 11 extends under this cardboard 10, being cut so as toprovide it with four integral flaps 12. These flaps extend upwardly against the outer faces of the side and end walls 7 and 8 and have their upper portions bent inwardly as at 13, over the uph `per edges of said walls. l
d An outer rectangular frame 14 snugly surrounds the frame 6 and th'e flaps 12, said frame comprising opposed side and end walls 15 and 16 connected at the corners of the frame and provided at their upper edges with integral iaps 17, these flaps being turned inwardly and lying upon the inturned portions 13 of the iaps 12. These fiaps jointly form `a top for the inner container and they vare preferably of such width astoleave a central opening 18 of desired size, through which the container may be filled with powder, said opening being usuall of a size to Excellent results have been obtained from accommodate an outlet nozz e of a well known form of box-filling machine "In constructing the outer frame 14, I make use of a single cardboard vstrip such as that shown in Fig. 5. At spaced points, this strip has notches 19 formed in one of its edges,` to define the ends of the flaps 17, and these'I notches may be formed by arl-ordinary corner-cutting machine, instead of requiring that specially constructed dies be formed, to cut the strip in the desired shape. The strip is transversely scored at the notches 19, as indicated at 20, defining the ends of the side and end walls 15 and 16, and said stripI is longitudinally scored at 21, from each notch 19 to the next notch, thereby defining the upper y edges of said walls. vBy bending the strip upon the scored lines 2 0, and suitably connecting its ends, the outer frame 14 is formed with the flapsv 17 then projecting upwardly. Preferably, a thin strip of paper 22 is glued around the frame 14 to hold the strip ends together and to give a more finished appearance to this portion of the frame, which later is exposed when the complete box is opened.
With the frame 14 standing as seen in Fig. 1, the lpaper sheet 11, the'piece of cardboard 10, and the inner frame 6, may be forced into it from above, by machine operations, said inner frame 6 serving to downwardly move the cardboard 10 and the paper l1 into the frame 14. During this operation, the iaps 12 will obviously beI upwardly folded between the walls of the inner and outer frames and they w 1ll projectl above these frames at the inner sides of the fiaps 17. Thus, when these 4flaps are folded over to jointly form a top for the inner receptacle, the projecting portions of the flaps 12 will be similarly folded/ as indicated at 13 in Fig. 3, so that'there is no danger of the iiaps 12 pull'inof out from engagement with the innerandb outer frames, although not glued thereto.
The inner container as above described, is filled through the opening 18, while it stands as seen in Figs. 2 and 3. After filling, the bot-V tom section B of an outside box is inverted and slipped onto jthe upper portion of the filled receptacle, as indicated by dotted lines in Fig. 8, said bottom section .being glued either to the flaps 17 orto theside and end -walls of the outer frame A14. Now, the entire filled assemblage is inverted and the top rsecf tion T of the outside box is slipped over the l portion of the frame 14 projecting beyond the bottom section B. Inlthis condition, the package is marketed.
. When a purchaser of a box of the powder, l
wishes to open the saine, she-removes the top T, tears or cuts the paper 11 andI removes the cardboard 10, thus gilving access `to the powder. l
Leest/itatl is invited to the fact that-while the flaps 17 are preferably of such proportions as to leave the opening 18, they might in some instances bewider so as to form a complete top for the inner receptacle, provided with nol opening. With this construct-ion, it' would of course 4be necessary to ll the containerwith the pow/der while the flaps stood upright, folding said flaps inwardly, into co-operative relation, after filling.`
