Description:

My invention consists in a collapsible shopping bag of novel construction.

The invention has as its principal object to provide a bag sufficiently capacious to receive a copious quantity of articles and yet capable of being collapsed and rolled into a package small enough to be carried in a lady's handbag or pocketbook.

A further object of my invention is to provide a bag so constructed that it will remain upright 1, when filled and will nevertheless be collapsible, when empty, into a small compact package.

An important feature of the invention comprises the combination of foldable members disposed at the mouth of the bag and tending nor- 1' mally to keep it open, and a stiff insert disposed in the bottom of the bag and normally cooperating with the members at the mouth to keep the bag open and in a condition permitting articles to be easily introduced therein. 2 A shopper may carry the rolled bag in a pocket or handbag until it comes time to carry articles in it; then the bag may instantly be shaken out ready for use.

These and other objects and features of the 2I invention will be more readily understood and appreciated from the following detailed description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawing, in which: ;30 Fig. 1 is a plan view of a bag constructed according to my invention and shown in open position, Fig. 2 is a view in cross-section along the line 2-2 of Fig. 1, Fig. 3 is a view in side elevation showing the first steps in folding the bag, Fig. 4 is a view in cross-section along the line 4-4 of Fig. 3, and Fig. 5 is a view in side elevation showing the bag almost completely rolled.

As shown in the drawing the bag body may conveniently be made of cloth, although any flexible, collapsible sheet material may be used. The body includes a pair of side walls or panels 10 stitched together with their edges turned in as shown at 15 in Fig. 1. To the lower edges of the side walls 10 I stitch a bottom wall or panel 12.

Conventional looped handles 14 are secured to the mouth of the bag. Around the mouth of the bag is stitched an external cloth binding strip 17 in which are enclosed four reinforcing strips 16 of cardboard, two of such strips 16 being distributed along the upper margin of each side wall 10. Preferably 65 the cardboard strips 16 are cemented to one inside surface of the binding strip 17. The strips 16 stiffen the bag mouth but permit its sides to be folded about longitudinal or vertical fold lines into four sections, there being a hinge action at the four points 18 where the separate cardboard strips 16 meet. The result is a collapsible stiffener disposed at the mouth of the bag.

In the bottom of the bag two stiff pieces 20 of 0 cardboard are cemented on one suirface to a sheet of cloth 22 and on the other surface to the inside of the cloth bag bottom 12. The pieces 20 and the cloth 21 are shaped to fit the bottom 12 and each piece constitutes one half of the bot5 tom. Between them is provided a hinge or central fold line which permits the bottom to be folded in half so that the bag may be rolled into a compact package half as long as the bottom of the open bag.

When the bag is unfolded, the strips 16 naturally tend to open the mouth of the bag and hold it open in quadrilateral or approximately square shape, particularly since the inturned edges 15 of the panels 10 are disposed at the apices 18 of the angles formed by the strips 16. The stiffener in the bottom of the bag urges the side walls apart and also provides a flat base. The result is that the bag may easily be filled, since it is not necessary to hold the mouth open with one hand and fill the bag with the other. Furthermore, when the bag is full, the flat base provides a support making it possible to set the full bag down without having it tip over.

When it is desired to collapse the bag, the bottom 12, with the stiffeners 20, is folded over into the position shown in Fig. 3. Then the bag is folded in half along the fold line 24 (as shown in Fig. 3), the fold line coinciding with the junction of the pieces 20 in the bag bottom and with the junctions of the four cardboard strips 16 in its upper edge. Finally the folded bag is rolled up from the bottom to make a small compact package. Fig. 5 shows the bag almost completely rolled. For example, a bag 151/2 inches high and having side walls about 13 inches wide may be rolled into a flat rectangular package approximately seven inches long, four inches wide and one inch thick. These dimensions are not critical, but merely illustrative.

A bag constructed according to my invention may be manufactured simply and at low cost.

There are of course, many minor variations which can be made in the construction shown in the drawings without departing from the scope of the appended claims.

Having thus described and illustrated my invention, I claim as new and desire to secure by Letters Patent of the United States: 1. A shopping bag comprising two side panels foldable about longitudinal fold lines into four overlapping sections of substantially equal width, a stiffening insert coextensive with the upper edge of each panel section and movable to form a quadrilateral to hold the mouth of the bag open, and a bottom having two flat stiffening members arranged to be folded together with the bottom into half the width of one panel, the fold line of the stiffening members in the bottom being in alignment with an opposed pair of longitudinal fold lines of the panels, whereby the collapsed bag may be rolled into a compact package.

2. A shopping bag comprising side panels foldable about longitudinal fold lines into four overlapping sections of substantially equal width, a stiffening insert coextensive with the upper edge of each panel section and movable to form a quadrilateral to hold the mouth of the bag open, said inserts being located in the panels to provide a hinge at the edge of each side section, and a bottom having a pair of hinged rigid inserts arranged to be folded transversely on a fold line in alignment with a pair of opposed hinges between the inserts at the upper edges of the panel sections, whereby the collapsed bag may be rolled into a compact package half the width of one panel.
