PACKAGE SEALING Filed M y 192 IIquzzz I v J Patented June 24, 1930 UNITED STATES JAMES G. SHAW, OF SAN JOSE, CALIFORNIA PACKAGE SEALING Application filed May 3, 1928. Serial No. 274,875.
This invention relates particularly to a method of sealing the open end of a bag or carton.
It is one object of the invention to provide a simple method of the character indicated that will in the one operation render the package air tight and also reduce the size of the package to closely encompass its contents.
It is another object of the invention to pro vide a method whereby the package may be sealed as indicated without coverin any of the outer surface of the container t at may be advantageously used for advertisements or other printed matter.
It is also an object of the invention to pro vide a method of the character indicated wherein the sealing means is rendered invisible by the forming and sealing of the package.
Finally it is an object of the invention to provide a method of the character indicated whereby a seal may be made that will be strong, urable, and highly efiicient in its practical application, and yet be quickly and easily broken when the package is to be opened.
In the drawings:
Figure 1 is a perspective View of the sealing element embodied in my invention.
Figure 2 is a pers ective view of a portion of a paper sack wit the sealing element in the first position.
Figure 3 is a perspective view of a portion of a paper sack with the sealing element folded into the second position.
Figure 4 is a perspective view of a portion of a paper sack with the sealing element in its final'position.
Figure 5 is a perspective view of a portion of a carton with the sealing element in position thereon.
Referring now more particularly to the drawing I show at 1 a short strip of suitable material such as paper having its two sides as 2 and 3 covered with a suitable gum, mucilage or other adhesive substance.
In carrying out the invention the sack 4 is filled to the desired height as 5, its open end is closed by bringing the side edges together as indicated at 6, and the gummed paper strip is folded down thereover to effectually seal the same throughout its length as shown at 7. The upper portion of the sack is now folded over upon itself as shown at 8, the contacting surface of the strip 1 adhering thereto. Finally the folded upper portion of the sack is again folded over, but this time flat upon the top of the sack as shown at 9 the contacting surface of the seal adhering to the body of the sack and completing the operation.
By means of this method the strip 1 may first be moistened upon side 3 and the bag or sack sealed, then moistened upon the outwardly and oppositely directed portions of side 2 and folded as described thereby forming a positive seal and shaping the sack into a substantially rectangular package. By means of this method the entire exterior of the sack is left unobstructed, and the package is sealed and formed much more quickly and economically than by those methods now commonly in use.
In order to carry out this method to the best advantage it is desirable that the sack be filled to a given level spaced from the top of the sack a distance substantially equal to the full width of the sealing strip, although satisfactory results may be obtained where the distance is greater than the width of the sealing strip.
In Figure 5 the method is applied in a modified form to the sealing of a carton 10. Here the strip 1 is folded over the free outer edge of a flap 11 so that when the flap is pressed down it will be immediately sealed to the underlying flaps 12. When the other large flap 13 is to the strip 1, thereby completing the sealing process.
It is to be understood, of course, that while folded down into position it is sealed I have herein shown and described the preferred embodiments of the invention, changes in the method may be made within the scope of the appended claim.
I claim:
The method of sealing a package which consists in providing both sides: of a strip of foldable material with adhesive, closing the package by bringing the opposing edges of the open end together, folding the said strip over the closed edges to seal the same, folding the sealed end of the package over upon itself twice in succession to bring both sides of the outer surface of the strip into sealing engagement therewith.
JAMES G. SHAW.
