Sept. 22, 1964 c. c. PEARL AIR SICKNESS BAG Filed Oct. 9, 1962 INVENTOR BY W W QM ATTORNEYS.

fFOLD FIRST ON THIS LINE 54 56 THEN FOLD ON THIS LINE I AFTER CLOSING TOP or BAG United States Patent 3,149,771 AIR SICKNESS BAG Curt Charles Pearl, Forest Hills, N.Y., assignor to Equitable Paper Bag Co. Inc., Long Island Qity, N.Y., a corporation of New York Filed ()ct. 9, 1962, Ser. No. 229,315 2 Claims. (Cl. 229-55) This invention relates to bags and more especially to bags which are suitable for holding liquids and which can be conveniently sealed at their upper ends after filling. More especially the invention relates to bags which are suitable as air sickness bags, for use by passengers of air lines.

It is an object of the invention to provide an air sickness bag which can be sealed more convenientlyafter being used; and the invention provides pressure-sealing adhesive and makes provision for folding the upper end of the bag with a double fold that results in a strong and leakproof seal.

Another object of the invention is to provide an air sickness bag of more economical construction and made from a flattened tube but with inward folds that produce a gusset-type bag. The preferred construction has the confronting faces of the bottom portion of the tube sealed to one another and with a reinforcing strip folded over the lower end of the bag and extending for a limited distance up the front and back of the bag.

Another object is to provide an air sickness bag in which the top of the bag is flattened and folded along a transverse line with confronting faces of the folded front of the bag sealed together by adhesive; and with a second fold, in the same direction as the first fold, and along a line parallel to that of the first fold, bringing the folded portion of the back of the bag into confronting relation with the front of the bag, and with adhesive sealing the confronting back and front surfaces. 7

Other objects, features and advantages of the invention will appear or be pointed out as the description proceeds.

In the drawing, forming a part hereof, in which like reference characters indicate corresponding parts in all the views:

FIGURE 1 is a perspective view, partly broken away, of a bag made in accordance with this invention and showing the bag opened on one side and still folded on the other;

FIGURE 2 is a greatly enlarged sectional view on the line 22 of FIGURE 1;

FIGURE 3 is a fragmentary view showing a portion of the back of the bag;

FIGURE 4 is a greatly enlarged sectional view taken on the line 44 of FIGURE 1; but with the protecting strip peeled back farther than shown in FIGURE 1;

FIGURE 5 is a sectional view, at the same plane of section as FIGURE 4, but with the top of the bag folded along one fold line; and

FIGURE 6 is a view similar to FIGURE 5 but showing the top of the bag folded along a second fold line to obtain a double fold.

FIGURE 1 shows a bag 10 formed of a tube of sheet material and having a longitudinal lap seam 12. The tube is flattened by an inward fold 14'along both sides of the tube. In FIGURE 1, the fold 14 is shown flat on one side of the bag, but the other side of the bag is expanded to show the way in which it opens up as a gussettype bag.

taken FIGURE 2 shows the way in .which the bottom of the bag is sealed. The confronting faces of the bag at the 7 fold 14 are secured together by adhesive 16. In the pre'- tube at the lower part of the bag and only at the lower part, the upward extent of the adhesive 16 being shown in FIGURE 1.

The sheet material used for the bag 10 is preferably kraft paper with its inside surface coated with a plastic to make the paper waterproof. Forty-pound kraft paper coated with five-pounds of polyethylene has been found to. be satisfactory in practice and economical in cost. The plastic coating should be a heat-sealing plastic for best results; and in the construction shown in FIGURE 2, the confronting faces of the inside of the tube are heatsealed to one another at the bottom of the bag; the plastic coating providing a convenient means for heat-sealing. The polyethylene coating on the inside confronting faces of the tube is indicated in FIGURE 2 by the reference character 16'.

A reinforcing sheet or strip 29 is folded over the bottom of the bag 10 and extends for a limited distance upwardly across the front and back surfaces of the bag. This reinforcing strip 20 is secured to the outside surface of the bag by adhesive 16. The reinforcing strip 20 extends upwardly for a distance somewhat greater than the upward extent of the adhesive 16 on the folded portion of the bag.

Although the adhesive 16' ordinarily extends over the entire inside area of the reinforcing strip 20, the heat is applied to only a portion of the height of the strip'20 and the heat seal, therefore, does not extend to the top of the reinforcing strip 20. Although the strip 20. can be applied to the bag in other ways, this heat-sealing for a limited height has advantages in the manufacture of the bag. One advantage is that manufacturing tolerances can be wider, and the heat is applied to areas of substantial thickness. 7

A stronger reinforcement is obtained by having the strip 20 extend some distance beyond both sides of the bag, and these extending portions are sealed together, as shown in FIGURE 2. It will be understood that the thicknesses of the sheet material are greatly exaggerated. in FIGURE 2 for greater clearness of the illustration, and that the actual variations in the distances across the bag are much less in actual practice.

The bag has a front side 32 and a back side 34. The sides that fold inwardly to make the fold 14 are indicated by the reference characters 36 and 38. The front 32 has an area, extending downwardly from its top edge, coated with a pressure-sealing adhesive 40. This area of adhesive 40 extends across the full width of the front 32. In the construction illustrated, the adhesive 40 is applied to the front 32 by having the adhesive 4% coated on a top reinforcing strip 42 which is fastened to the front of the bag by other adhesive 44. This adhesive 44- may be any kind of glue such as is used for making bags. The strip 42 preferably extends somewhat beyond the sides of the front 32.

A protecting strip 46 covers the pressure adhesive 44. This protecting strip 46 extends for the full width of the strip 42 and extends downward some distance. beyond the strip 42, or at least beyond the adhesive 40, to facilitate gripping an edge of the protecting strip in order to peel it off when the bag is to be closed. It is advantageous to have the-adhesive 44) extend all the way to the top of the bag; and in the preferred construction the top edges of all sides of the bag are at the same distance from the bottom of the bag. I 7

FIGURE 3 shows the back of the bag, with the strip 42 extending beyond the side edges. There is a line 5% on the back 34 and extending transversely and substantially parallel to the top edge 52 of the bag. When the bag is to be closed, it is first folded forward-at the line 50; that is, it is folded away from the surface of the 7 back 34 on which the line 50 is printed. Indicia 54 are printed on the back of the bag, giving directions for folding the top after the bag has been closed.

There is another line 56 extending parallel to the line 50 and located some distance below the line 50 with indicia 58, indicating that a second fold should be made along the line 56.

FIGURE 5 shows the top of the bag closed and folded forward along the line 50. This fold brings the upper portion of the outside of the front 32 into a position confronting another area of the front 32 below the fold. The adhesive 40 on these confronting surfaces seals the bag closed across the full width of the folded top, as shown in FIGURE 5.

When the bag is next folded along the line 56, it comes into the condition shown in FIGURE 6. This second fold brings the upper portion of the back 34 into a position confronting an area of the front 32 and the adhesive 40 on this area of the front secures the confronting face of the back 34 to the corresponding area of the front 32. With this double fold and the corresponding seals, the bag is closed at the top in a manner which makes it not only leakproof for liquids, but also leakproof against the escape of malodorous fumes. The seals are strong enough so that the bags can be handled for disposal Without coming open.

From FIGURE 6 it will be evident that the extent of the adhesive 40, downward from the top edge of the bag, must extend below the line 56 for a distance equal to the height of the first fold; that is, for a distance equal to the spacing of the first fold line 50 from the top edge 52. The preferred embodiment of the invention has been illustrated and described, but changes and modifications can be made and some features may be used in different combinations without departing from the invention as defined in the claims.

What is claimed is:

1. An air sickness bag comprising a tube folded flat and with the lower end of the bag closed and sealed against leakage and with opposite sides of the tube folded inwardly to form a bag with gusset sides, the upper end of the bag having a top edge which is at substantially the same distance from the bottom of the bag around the entire length of the top edge, a reinforcing strip extending along the top edge of the front of the bag on the outside thereof and secured thereto, and forming a part of the front of the bag across the full width of the bag, a pressure-sealing adhesive covering an area of the outside of the front of the reinforcing strip across the full width of the bag, and downward from the top of the strip for a vertical distance that accommodates two lines of fold extending parallel to each other and to the top edge of the bag, and spaced from one another, the top of the bag being adapted to have its front and back sides closed against one another after the bag is filled and to have its front and back sides folded over along the upper line of fold to bring the upper part of the front of the bag into contact with an area of the adhesive'above the lower line of fold, and the front and back sides being adapted to fold also forwardly along the lower line of fold to bring the outside surface of the folded-over back of the bag into contact with the adhesive below the lower line of fold to seal the bag against the escape of malodorous fumes.

2. The bag described in claim 1 and in which the bag is made of paper coated over its entire inside area by polyethylene and coated with polyethylene on its outside surface only over the lower part of areas of the inwardly-folded confronting gusset surfaces near the bottom of the bag and for some distance upwardly from the bottom along both sides of the bag, the confronting coated outside surfaces of the inward folds of the gussets being fused together, and the confronting surfaces of the inside of the bag at the bottom thereof being also fused together to seal the bottom of the bag closed.
