It is a primary object of the present invention to afford a novel collapsible, disposable bag.

Another object of the present invention is to afford a novel, collapsible, disposable bag which is particularly well adapted for use in sick-rooms, hospital rooms, airplanes, and the like.

Collapsible, disposable bags for receiving and storing materials, such as, for example, bags of the type shown in US. Pat. Nos. 2,966,294, issued to George G. Pelfred on Dec. 27, 1960; 3,l44,l97, issued to Richard H. Milner on Aug. Il, 1964; 3,189,252, issued to Theodore A. Miller on June 15, 1965; 3,263,903, issued to Robert J. Waller on Aug. 2, 1966; and 3,282,412 and 3,297,152. issued to Arthur P. Corella on Nov. 1, 1966 and Jan. 10. I967, respectively, have been heretofore known in the art. However, collapsible, disposable bags of the type heretofore known in the art commonly have had several inherent disadvantages, such as, for example, being complicated in construction and operation; being difficult to feed material thereinto; being unreliable in the sealing of material therein so that they do not effectively protect against spillage or discharge therefrom; being difficult to open; or being complicated and expensive to manufacture, and the like. It is an important object of the present invention to overcome such disadvantages.

Another object of the present invention is to afford a novel, collapsible, disposable bag which is particularly well adapted for use by persons who are sick to their stomach.

An object ancillary to the foregoing is to afford a novel bag of the aforementioned type which may be readily used by such persons, even when they are unskilled in the use thereof.

Yet another object of the present invention is to afford a novel, collapsible, disposable bag which is particularly well adapted for use in receiving and storing vomit, and the like.

A further object of the present invention is to afford a novel, collapsible, disposable bag wherein the parts thereof are constituted and arranged in a novel and expeditious manner which enables the bags to be quickly and easily opened to a wide-open position, when they are to be used for receiving vomit from a person who is sick to his or her stomach, while permitting the bag to initially, automatically, but effectively seal itself against accidental reverse flow of the vomit therefrom, and permitting the bag to thereafter readily be more permanently and effectively sealed against such reverse flow and spillage therefrom.

Another object of the present invention is to afford a novel, collapsible, disposable bag which is practical and efficient in operation and which may be readily and economically produced commercially.

Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawings which, by way of illustration, show a preferred embodiment of the present invention and the principles thereof and what we now consider to be the best mode in which we have contemplated applying these principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

DESCRIPTION OF THE EMBODIMENT SHOWN HEREIN A collapsible, disposable bag 1, embodying the principles of the present invention is shown in the drawings to illustrate the presently preferred embodiment of the present invention. The bag 1 embodies, in general, an outer body portion 2, an inner body portion 3, an upper end portion 4 and a pocket assembly 5, FIG. 1, as will be discussed in greater detail presently.

The outer body portion 2 of the bag 1 embodies two opposed, elongated, flexible outer side walls 6 and 7, FIGS. 2 and 3, which may be made of any suitable material, such as, for example, a suitable thermoplastic polymer sheet material, such as polyurethane. The walls 6 and 7 are secured together, in liquid-tight relation to each other along their bottom end edges 8 and their longitudinally extending,

opposite side edges

9 and 10, to thereby completely close the outer periphery of the outer body portion 2 below the upper edge 11 thereof. The upper edges of the side walls 6 and 7 are left unsecured to each other to thereby afford an entrance opening into the outer body portion 2, for a purpose which will be discussed in greater detail presently.

The inner body portion 3 also embodies two opposed, elongated,

flexible side walls

12 and 13, FIGS. 2 and 5, which may be made of any suitable material, such as, for example, a suitable thermoplastic polymer sheet material, such as, the aforementioned polyurethane. The

walls

12 and 13 are secured together in liquid-tight relation to each other along their opposite longitudinal edges 14 and 15, the upper and lower edges of the

side walls

12 and 13 being unsecured to each other so that the inner body portion 3 is tubular, in form, for a purpose which will be discussed in greater detail presently. In the preferred form of the invention shown herein, the upper end portions of the side edges 14 and 15 of the

sheets

12 and 13 are disposed between and secured to the corresponding portions of the

side edges

9 and 10 of the sheets 6 and 7, and the portions of the side edges 14 and 15 disposed therebelow taper downwardly and inwardly toward each other to afford a substantially cone-shaped passageway, which is smaller at its lower end than at its upper end, and which is disposed in upwardly spaced relation to the lower end of the outer body portion 2.

The upper end portion 4 of the bag 1 also embodies two opposed, elongated,

flexible side walls

16 and 17, FIG. 2. While the

side walls

16 and 17 are flexible, they preferably are substantially more rigid, and of greater thickness than the

side walls

6, 7, 12 and 13, and preferably are made of paperboard.

When the bag 1 is disposed in flat position, the longitudinal edges 18 and 19 of the

walls

16 and 17 thereof extend transversely to the length of the outer and

inner body portions

2 and 3, with the upper longitudinal edges 18 being convex outwardly, or upwardly, as viewed in FIG. 1. The lower edges 19 of the

walls

16 and 17 are shorter in length than the upper edges 18 thereof, and the

opposite side edges

20 and 21 of the upper end portion 4 slope downwardly and inwardly toward each other from their junction with respective ends of the upper edges 18 to their junction with respective ends of the lower edges 19, FIG. 1.

Preferably, the

side walls

16 and 17 are made from one piece of paperboard, and are connected to each other at the side edge 20 thereof along a fold line. At the other side edge 21, the

side walls

16 and 17 are secured together in liquid-tight relation to each other by suitable means such as a flap 22 carried by the side wall 17 and adhesively secured to the outer face of the side wall 16, FIG. 1. Each of the

side walls

16 and 17 has a score line 23, which is concave inwardly or downwardly, as viewed in FIG. 1, the score lines being disposed in parallel relation to each other, and extending between the upper ends of the

side edges

20 and 21, when the

side walls

16 and 17 are disposed in the aforementioned flat relation to each other, only the score line 23 on the side wall 16 being shown in FIG. 1.

The lower end portion of the upper end portion 4 of the bag 1 is of such size that it may be inserted downwardly into the common entrance opening afforded by the upper ends of the outer and

inner body portions

2 and 3, in close fitting relation thereto. The upper end edges of the

side walls

6 and 12 are secured to each other and to the outer face of the side wall 16, and the upper end edges of the side walls 7 and 13 are secured to each other and to the outer face of the side wall 17 by suitable means such as, for example, by heat sealing.

Preferably, when the bag 1 is disposed in normal, stored position, it is disposed in flat position, as shown in FIG. 1. When it is desired to open the bag 1, such as. for example. when a person desires to use the bag 1 as a receptacle into which he or she may vomit, the bag 1 may be quickly and easily opened by pressing the

side edges

20 and 21 of the upper end portion 4 thereto inwardly toward each other. Such pressure on the

side edges

20 and 21 may be continued until the upper end portion 4 is disposed in fully open position, wherein it preferably is substantially circular in transverse cross section, and affords a substantially cone-shaped opening for the bag 1, in the form of a funnel which tapers downwardly and inwardly to the common entrance opening between the side walls 6 and 7 of the outer body portion 2 and the

side walls

12 and 13 of the inner body portion 3, FIG. 4.

With the bag 1 thus in open position, when material is fed into the upper end of the upper end portion 4 thereof, the material passes downwardly through the upper end portion 4 into the upper end portion of the inner body portion 3, from which it passes downwardly through the tubular-shaped inner body portion 3 into the lower end portion of the outer body portion 2. While the

side walls

12 and 13 of the inner body portion 3 are normally disposed in juxtaposition to each other, they may open outwardly relative to each other to permit the passage of such material from the upper end edges thereof when the latter have been opened by the funnel 4. However, after the material has passed downwardly through the inner body portion 3, into the outer body portion 2, the natural resilience of the

side walls

12 and 13 causes them to again move into juxtaposition to each other, below the upper end portion 4 of the bag 1, to afford an effective valve member for preventing reverse flow or discharge from the outer body portion 2 upwardly through the inner body portion 3.

After the bag 1 has thus been used to receive material therein, the upper edge portion 24 of the upper end portion 4 of the bag 1, above the score line 23, may be folded inwardly toward the side wall 17, and the upper edge portion 25 of the side wall 17, above the score line therein, not shown, may be folded over the outer face of the upper edge portion 24, as shown in FIG. 7, to thereby afford an effective closure for the upper end of the bag 1. The thus closed bag 1 affords an effective closed container for storing the material in the outer body portion 2, outwardly of the inner body portion 3, as shown in FIG. 5, until the bag 1, with the material therein, is to be disposed of, such as, for example, by depositing the same in a suitable receptacle.

The pocket assembly 5, FIGS. 1, 4 and 5, comprises two opposed, elongated

flexible strips

26 and 27, made of a suitable material such as, for example, a thermoplastic polymer sheet material, such as, polyurethane. The

strips

26 and 27 are secured together at their opposite ends, and to the

opposite side edges

9 and 10 of the outer face of the side wall 6 of the outer body portion 2 by suitable means such as, for example, the aforementioned heat sealing. The lower edges 28 of the

strips

26 and 27 are secured together in liquid-tight relation to each other by suitable means such as the aforementioned heat sealing, and preferably are secured together along a line, such as the line 29, FIG. 1, disposed intermediate the ends thereof to afford two

pockets

30 and 31, FIG. 3, into which material, such as, for example, a stick of gum 32 and a towel or napkin 33 may be disposed, so as to be readily accessible for use by the person using the bag 1, after it has been closed in the aforementioned manner.

With the bag 1 constructed in the aforementioned manner, it will be seen that it affords a compact unit which may be stored, in unused condition, in a relatively small space, and in a location in a room or airplane, or the like, wherein it is relatively readily accessible for emergency use.

Also, it will be seen that it affords a bag which may be quickly and easily opened for use, and which is effective to automatically afford a temporary seal against reverse flow therefrom, and the top of which may be quickly and easily manually closed, after the bag has been used.

Also, it will be seen that the bag 1 disclosed herein affords a compact, relatively complete kit, which not only affords a receptacle into which a person, who is sick, may vomit, but also embodies a construction which enables material to be afforded in a readily accessible manner, which may be used for freshening up, and the like.

Also, it will be seen that the present invention affords a novel bag of the aforementioned type which is practical and efficient in operation, and which may be readily and economically produced commercially.

Thus, while we have illustrated and described the preferred embodiment of our invention, it is to be understood that this is capable of variation and modification, and we therefore do not wish to be limited to the precise details set forth, but desire to avail ourselves of such changes and alterations as fall within the purview of the following claims.
