PARAFFIN BAG Filed Aug. 3, 1934 Patented July 2l,V 1936 PATENT OFFICE PARAFFIN BAG Stanley B. Howard, Milton, assignor to Pneumatic Scale Corporation, Limited, Quincy, Mass., a corporation of Massachusetts Application August 3,
Claims.
This invention relates to a paraffin bag, and more particularly to a parafiin liner for a carton. The invention has for an object to provide a novel construction of bag possessing superior moisture-resisting properties, which may be economically manufactured and is particularly adapted for use as a paraiiin liner for a carton. With this general objectin view and such others as may hereinafter appear, the invention consists in the paraffin bag and in the paraffin liner fora carton hereinafter described and particularly defined in the claims at theA end of this speciilcation.
In the drawing illustrating theinvention as embodied in a paraffin liner for a carton, Fig. 1 is a perspective with portions broken away, `illustrating the liner with the carton; Fig. 2 is a similar view illustrating the liner ready for introduction into the carton; Fig. 3 is a plan of a paraffin coated p aper web from which the present liner may be produced; Fig. 4 is a view in side elevation illustrating the liner in its partially completed condition; Fig. 5 is a plan view of the nner in' the condition shown in Fig. 4; and Fig. 6 is an end elevation of the lower portion of the liner shown in Fig. 4.
Prior to the present invention, many attempts have been made to produce a satisfactory param liner for a carton, but the results of all of these attempts have for one reason or another been commercially unsatisfactory. The general commercial practice has been to produce the paraffin liner from a web of paraiiin paper by folding the web to form a bag rectangular in section and with overlapping side seams and then to apply heat to the side seams to fuse the paraiiin to cause the overlapping portions to adhere together. The eifect of the heat when applied to the overlapping side seams has been to melt the paraflin and cause it to run from the overlapping strip leaving an overlapping side seam at each side of the liner which is deficient in parain, and in most instances the resulting side seams are converted into substantially uncoated strips possessing little or no moisture resistance and destroying most of the effectiveness of the paraffin lin'er as a moisture-resisting agency.. The packaging of certain types of hygroscopic material hasl presented very serious packaging problems, and the use of paraffin liners has been resorted to in the attempt to provide a satisfactory moistureresisting liner and package, in order to prevent access of the moisture-laden air into the interior of the package. When the continuity of the coating of paraffin is substantially destroyed by 1934, serial No. 738,257
the application of heat to the side seam. even though enough parafdn remains upon the side seam to effect the adherence of the overlapping portions of the seam, nevertheless through this deficient strip the moisture-laden air can readily 5 pass,l destroying the effect which is sought to be produced by the use of the paraffin liner.
Other attempts to solve the problem have' included the use of special adhesives, but these materials have all included solvents whose pungent odors have rendered their use prohibitive for the packaging of food products.
In accordance with the present invention the improved bag is produced of a unitary length l0 of paper provided upon both surfaces thereof l5 with coatings l2 of paraiiin or equivalent waterproong material of a substantial thickness sufiicient to effectively resist the passage of moisture through. The paraflin coating upon that surface of the sheet which is to constitute the inner surface of the liner or bag is arranged to terminate at a line I4 spaced from each marginal edge I5 of the sheet a distance corresponding to the desired width of side seam to be produced in the bag when formed. This produces at each marginal edge of one surface of the sheet a strip which is free or substantially free from paraffin.
In producing the present bag, the unitary length I0 of the parafn-coated paper is then 3o folded preferably to form a rectangular shaped bag, and the folds are made so as to bring into contact the two substantially parain-free strips or surfaces, and the latter are adhesively aixed to each other by glue or other adhesive, producing a strong and durable side seam. In addition, the formation of the bag is arranged so that the coating l2 of parain upon the inner. surface of each half of the bag is brought into abutment or contact as at 20, 2i, so that as a result of this construction the ultimate bag is provided with an interior coating of parain which extends entirely around the entire inner surface thereof and forms a complete moisture-resisting barrier of substantial thickness, rendering the paraffin bag thus produced highly eicient as a moisture-resisting container, and particularly as a moisture-resisting liner for a carton or package.
After the side seams have been adhesively aiiixed 'together by glue, producing an exceptionally strong paper to paper contact and seam, the side seams may and preferably will be folded into contact with the end surfaces of the bag in the manner illustrated in Fig. 1, and the projecting lower portion of the sides of the bag folded 55 up into the position shown in Figs. 1 and and as a result the complete paraiiin liner thus formed is ready to be inserted into the package.
The present construction of bag, involving the formation thereof from a single unitary length of coated paraiiin web, produces a most satisfactory moisture-resisting bottom of the bag. Here- `tofore, considerable difficulty has been experiadhesive in the production of side seams.
While the preferred form of the invention has been herein illustrated and described, it will be understood that the invention may be embodied in other forms within the scope of the following claims.
Having thus described theinvention,- what is claimed ls: l
1. A moisture-resisting bag comprising a body portion formed of a unitary length of paper coated on both sides'with a layer of parain of substantial thickness and having the marginal portions of the surface which is to form the interior of the bag substantially free from paran, said paper length being folded in such a manner as -to permit the paraffin-free surfaces to be brought into contact and adhesively secured together to form outwardly projecting side seams and in such a manner that the paraffin layer on the'interior of one half section of the bag will meet with the corresponding parafn layer-of the other section, whereby the bag is provided with a wall of parafiin o'f substantial thickness over the entire inner surface thereof.
2. A moisture-resistingbag comprising a body portion including side portions and formedgof a unitary length of paper coated on both sides with a layer of parafdn of substantial thickness and having the marginal portions of the vsurface which is to form the interior of the bag substanis provided with a wall of parain of substantial thickness vover the entire inner surface thereof,
said outwardly projecting side seams being folded against the side portions of the bag.
3. A parailin coated bag composed of a single parain-coated paper sheet folded to form the body of the bag and to form outwardly projecting side seams extending lengthwise of the bag, the contacting faces of the paper forming said side seams being paramn-free and tightly glued tothe body portion of the bag with a uniform and moisture-resisting paraln coating.
4. A moisture resisting bag of the seamless bottom type comprising a parafiin coated paper sheet having its side edges folded to form side portions with outwardly projecting margins extending lengthwise of the bag, said margins having their contacting faces substantially parafiinfree and adhesively and tightly affixed to one another to form side seams with the parafn layer on the interior ofv one half section of the bag meeting with the corresponding parailin layer on the other half-section of the bag, said side seams being'folded against opposed side portions of the bag. f
5. A moisture-resisting bag comprising a paramn-coated sheet folded to form the body of the bag with outwardly projecting side seams extending lengthwise of the bag, the contacting faces of the paper forming said side seams being substantially paraiiin-free and adhesively and tightly ailixed` to one another whereby to form a bag possessing a high degree of moisture resistance.
