To it may concern:
Be it known that I, EDWIN F. HULBER'r, a citizen of the United States, residing at Milwaukee, in' the county of Milwaukee and State of Wisconsin, have invented certain new. and useful Improvements in Sealed Receptacles, of which the following is a specification, reference being had therein to the accompanying drawings, forming a part thereof.
My'invention relates to an improvement. 'in paper receptacles and more especially those which are adapted to contain fine powdery materials, and the primary object of the invention is to provide a receptacle composed of moisture proof paper and folded in such a manner as to bring all of the free edges either to the mouth thereof in lapped relation or close thereto and folded in the ends thereof and sealed thereby, and to do the same with the use of a minimum amount of paper.
It is a further object of the invention to have a receptacle that may be easily made by automatic machinery, may be made out of a square sheet of paper and one that provides a better closure because the cumbersome top folds reviously in use are avoided. I am also enab ed by my invention to form a better closure and more com letely look all of the openings. I am furt er enabled to produce a bag which is smooth on both sides thereof, all the folds being on the ends thereof, thus giving me not only an article of improved appearance but also a fiat space available for decoration or the printing of either advertisements, directions, or such other matter as it may be desired to place thereon. in making the be with short folds of comparatively few s eets of material, so that the receptacle may be produced by machinery with a greatly increased rapidity o ver methods nowin use and without the tearing of the material when the same is ironed hard to complete the closures. Furthermore, the use of any paste, metallic fastening means, ton es, or punched fasteners in any part of this bag is avoided. I
In the accompanying drawin Figure 1 showsa plan view of the sheet from which the receptacle is folded; Fig. 2 is a perspee tive view of the receptacle in which the pnmary folding has taken place; Fig. 3 1s a A further improvement consists.
perspective view of the same in which the secondary folding has taken place; Fig. 4 shows in pers ective the receptacle completed except t e closure; Fig. 5 shows in perspective the first fold of the closure; Fig. 6 the completed closure; and Fig. 7 an opt onal additional closin means by corrugation of the ends thereo In making the bag the blank of Fig. 1 1s preferablya square of parafiin paper or so-called wax paper and it is folded to form the bottom 1, smooth sides 2, end pieces 3, and wings 4. The end pieces 3 meet the sides 2, the wings 4: being folded outwardly therefrom in the edge 5. These wings 4 are then folded so as to lap over each other and the ends 3 as shown in Fig. 3, and then after the bag has been filled with the mater al it is to carry the upper extension of the sides 2 or flaps 6 are brought together as shown m Fig. 4, the ends 3 and wings 4 are then indented sharply as shown in Fig. 4 and the edges 5 and the topmost portion of the wings 4 are sharply ironed to form a sharp closure which will prevent the drawing up of the powdered contents.
be top sea is effected by bending the flaps 6 back upon the sides 2 in excess of 90 degrees as shown in Fig. 5 and then again Having completely described my invention, I claim:
A smooth sided sealed receptacle formed from a single square sheet of material, the bottom being laid out upon the diagonal thereof, all of the corners of the sheet being brought .to points above the mouth of the receptacle, the receptacle being formed, closed, and sealed by then folding the free edges into sharply acute angles and making sealing corners by the intimate contact thereof.
