Application March 19, 1934, serial 10,716,259

y l 'sclaims (c1. 22e-si) This iinvention relates to a closure for the open end of a tubular blank or bag, as well as to the method of producing said closure.

An object of the invention is to provide a clo-4 sure for the open end of tubular blanks orfbags, or envelopes by means'of which the merchandise contained within the blank, bag, or envelope,

will be prevented from escaping therefrom, as

well as prevent the ingress of outside air into the 1o blank bag, or envelope, todeteriorate in whole or in part, the merchandise contained therein.

A further object of .the invention is to provide a. closure for the open end of a tubular blank bag or envelope, formed out of thematerial adjacent the opene end of the blank bag, or envelope, by a succession 'of diagonal and lateral folds, all of which are secured to the blank bag, or envelope,

and to each other. f A

- A still further object of the invention is to provide a closurefor either one or' both ends of a .tubular blank, out of which a bag or envelope is to be formed, which will be superior in point of simplicity, inexpensiveness o'f construction,l posi-A tiveness of operation, and facility and conven- 25 ience in use and general emciency.

In this specication and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in othery forms; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

In the annexed drawing:

Fig. 1 represents a plan View of a bag blank, or of a length oi tube material having the cre^ase lines indicated thereon, indicated to make a elosure for an end thereof.

Fig. 2 is a view illustrating the state of the which the nal step of folding the end closure is modined ircrn that shown in Figs. 4 and 5.

lFig. 7 is an enlarged section taken through Fig.

6 on theline "lii. r e is a vieta of a length ci tube or of a bag blank, having the crease lines at one `end`thereof to form a closure in accordance with my invention. i

, Fig. 9 is a viewjllustrating the state of the blank shown in Fig. 8 after the completion of the 5 folding operation. u

Fig. 10 is a cross section taken through Fig. 9 on the line lli-l0.

In detail the construction illustrated in the drawing comprises a.. length of tubed material, .10 which in the process of manufacture Ais formed from a single width of 'material .in accordance with conventional practices The kopposite longi tudinal side edges of the tube may be of the straight type as shown, or said opposite side 15 edges may be folded inwardly. It is a conventional and well-known practice in the industry, to make the side edges of the blank tubes with either the straight or folded side edges heretofore referred to; 1ikewise, it is a conventional 20 practice' in the industry to close one end of the v tube blank by aconventional system of folds. thereby to form a bag or envelope. The closed end of the bag thus becomes, in practice; the bottom end of the bag. The standardized method 25 of closing the bottom end of a bag or envelope provides a closure which does not hermetically seal the parts together, and as a result merchandise within the bag may work its way out, or atmospheric air may pass into the bag to 'deteriorate 30 the freshness of the contents of the bag.

Bags or envelopes which are formed in the usual way out of any of the well-known bag materials, such as pulp stock, rag stock, waxed paper, glassine, transparent regenerated cellulose, or the 35 like, usually have the bottom end thereof sealed -or closed by the standardized type of fold. Where the bag or envelope is made ci moisture-proof material such as treated paper, or treated regenerated. cellulose, to lprevent moisture attacking 40..

vof making bags or envelopes. This tubed material may be of any material out of which it is possible to form bags, envelopes, or the like. In 50 Fig.v 1, I have shown e. length 'or blank of material indicated by the numeral i. at either one or the other or both of the open ends of the blank i, I fold the opposite corners 2 and incn massaal crease lim ente ci or face of the blank, so that an edge of the folded I co'rner 3 will overlap and lie on top of the folded corner 2.- At the point where the folded corners overlap, the same would be preferably secured to each other by an adhesive, either externally applied, or contained within the bag material.

Likewise, thegfolded corners Zand 3 would be joined to the face -of the bag over which they lie,l by some conventional securing means or adhesive.

In the second stepmf; forming my closure, I

fold the end of the bag or blank on a transverse Yso line 1, within the area of the folded corners, and

suitably secure the same onto the theretofore .folded corners 2 and 3, by means of adhesives or lthelike. The fold line 1` is arranged laterally or transversely, relative to the longitudinal axis of the bag or blank, and when the said end of the bag is folded on the line 1, as heretofore described, a seal isl provided which prevents the ingress of air into the bag. 'I'he tijanglilarend portion 8 of the bag,` in order to further close off the possibility of the bag contents escaping, may be folded inwardly on the transverse line 9 between the face of the bag and the overlapping folded corners, as shown in Fig. 4, or, folded inwardly on the line 9 to lie against the outer face of the folded corners 2 and 3 as shown in Fig. 5, or folded outwardly and downwardly, as shown in Fig. 6. Either of the positions into which the triangular portion 8 may be folded, as shown in Figs. 4, 5, and 6, are optional and each is clearly within the purview of the invention. Irrespective of the positon into which the triangular portion 8 is folded, it is suitably secured onto that portion of the ,bag against which it lies, either by means of adhesive', or the like.

Itis to b e understood that the rst and second ,steps of forming the end closure as shown in Figs. 2 and A3, as well as the final step shown in Figs. 4, 5, and 6, are eeoted mechanically and automatically. Where the open end of a bag is folded and closed in the manner heretofore described and illustrated in Figs. 4, 5, and 6,*it'is impossible for the bag contents to escape, and where the bag is made' out of moisture-proof material, such as waxed paper, or treated regenerated cellulose, the end closure itselfforms a hermetic seal, which prevents outside air from entering the bag and deteriorating the contents.`

It is to be understood that the illustrations shown in Figs. 4, 5, and 6, are not intended to depict solely the idea of forming a closure for what might be indicated as the bottom of a bag, but that the identical closure might be formed on theupper end of the bag.

In Figs. 8, 9, and 10, I have shown a tubular blank or bag Ill, which has the opposite corners Il and l2 of one end 'thereof folded on diagonal lines into overlapped relationship, the same as il-y4 lustrated and described in connection with Fig. 2. In the modified form shown in Fig.' 9, the trian' gular apex n of the blank is folded on a lateral line, back onto the face of the overlapping folded corners, and secured thereto Within the area of said folded corners by suitable securing means,

such as adhesive, or the like.

No matter what the material is out of which the bag may be formed, my particular type of enclosure is one which I have found to be absolutely 5 air tight. I have found that if a. bag which is made out of water-proof material, has an open end thereof closed by a closure folded in accordance with my invention, that the said bag will hold water and none of it will leak through the closure, and that the limit of time within which the bag will hold water, is dependent upon its resistance to decomposing attack by the water. Obviously, a closure which is substantially water tight, to hold water within a bag formed of waterproof material, will likewise prevent air from entering such a bag to deteriorate whatever merchandisel such a bag may contain.

Having' thus described this invention', what I claim and desire to secure by Letters Patent is: 1. In a tubular blank having square ends, a

permanent/closure for an end of said blank comprising corners at one end of said blank folded inward on one face o f the blank, whereby one corner fold overlaps the other so as to position the adjacent edges thereof parallel, and having the end of the blank and the folded corners folded upon the face of the folded corners and secured thereto.

2. In a tubular blank having square ends, a

permanent closure for an end of said blank comprising corners at one end of said blank folded 'inward on one face of the blank, whereby one corner fold overlaps the other so as to position the adjacent vedges thereof parallel, and having a portion of the end of the blank and the folded corners folded upon the face of the folded corners and secured thereto, and the remaining portion of the end of the blank and the folded corners refolded over upon itself and secured 40 thereto. 3. In altubular blank having square ends, a permanent Aclosure for. an end of said blank comprising cornersat one end of said blank folded inward on one face of the blank so that the ad- 15 jacent edges overlap and are parallel to each other, and having the end of the blank and, the

' folded corners folded laterally and secured to the portion of the end of the blank and the folded corners folded upon the face of the folded corners and secured thereto, and the remaining portion of the end of the blank and the folded corners refolded over upon itself and secured thereto.

5. The method of permanently closing the square open end of a bag or blank, comprising,

ners to the face of the bag or blank, and folding y the end of the bag or blank on a transverse line 0 within the area ef the folded corners and securing the same thfereto.
