Application May 28, 1952, Serial No. 290,425
6 Claims. (Cl. 226-59) This invention relates to supports for disposable refuse containers and to combinations of such supports with such containers.
Considerable has been done in the field of providing easily usable, readily accessible garbage and refuse containers for use in the home, restaurants, hospitals, etc. The most common receptacle provides a small can, or pail, to receive the refuse, which can, when full, is removed and the contents thereof are dumped into a larger can. Then, for proper sanitation, the small can must be washed or scrubbed out. Such washing, or scrubbing, after each use is sufiicient of a nuisance that the housewife or other user have come to employ paper bags inside of such cans to receive the refuse. The filled paper bags are removed and dumped, thus obviating the necessity of scrubbing out the can so often.
The next step to this has been merely to eliminate the use of the small can and its receptacle entirely, and to merely employ paper bags kept under the sink, or some other convenient enclosure. This use of paper bags saves considerable work, but is not entirely satisfactory, for, at the outset, there is nothing to keep the sides of the bags from collapsing against each other. Furthermore, the ordinary paper bag is only suitable for accommodating substantially dry refuse, or garbage. Where too much liquid is present in the contents, the bottom of the bag quickly gets wet and is liable to disintegrate and dump the contents of the bag as it is being removed for deposit in a larger container.
Frames for suspending or holding open bags, usually of heavy paper or cloth, are employed, particularly in industry. These are principally exterior to the bag so are hardly suitable for home use, since they take up more room than the bag does. Furthermore, they involve various special provisions for the mounting of the bag. These take time and often some dexterity to operate.
This invention obviates the foregoing, and other drawbacks of the prior art developments, and does so by approaching the problem in a simple, straightforward man ner materially divergent from the prior practices. The invention contemplates a support for disposable bags of paper, or other suitable material, which support is received right within the bag, thus making a novel combination with it. The support is so formed that it will not injure the bag and it will hold it upright in open expanded position at all times. Furthermore, the support is so formed that no refuse will cling to it, whence it may be slid out of a filled bag and introduced into the next empty one without any need to clean it. The filled bag may then be disposed of.
The support of the invention may be made with the elements thereof in fixed relation if that is desired, or may be formed to be collapsible in various manners. Where collapsibility is provided it is such as to enable stowage of the support in a minimum of space when not in use. Regardless of collapsibility for that purpose, the construction of the support is such that when it is opened out to fit within a bag, the cooperation of the bag and Patented Jan. 17, 1956 ice support is such that the support holds the bag open and expanded while the bag maintains the support in set position. Finally, the whole construction of the support of the invention is so simple and economical that it can be made inexpensively, though capable of lasting a life-- time.
It is, accordingly, a principal object of the invention to provide fully effective support and disposable refuse container combinations.
Another object is to provide such combinations which occupy no more space than does the filled container alone. a
Another object is to provide such combinations wherein the container and support mutually cooperate to maintain each other in desired position.
A more particular object is to provide interior supports for disposable refuse containers.
A further object is to provide such supports Which can be removed from a filled container without extracting the refuse therefrom, or having any of the refuse cling onto them.
A still further object is to provide such supports which may be collapsed for stowage in a minimum of space.
A still further object is to provide such supports whose elements cooperate for the performance of multiple functions.
Further and more detailed objects of the invention will in part be obvious and in part be pointed out as the description of the invention, taken in conjunction with the accompanying drawing, proceeds.
In that drawing:
Figure l is a perspective view of a refuse containersupport combination in accordance with the invention.
Figure 2 is an enlarged perspective view of the support of Figure 1.
Figure 3 is a top plan view of a modified form of support.
Figure 4 is a perspective view thereof with portions of the legs broken away to conserve space.
Figure 5 is a detailed sectional view taken on line 5-5 of Figure 3 and illustrating the corner connector pivot arrangement.
Figure 6 is a perspective view of a further modification of the invention.
In the showing of the combination of Figure l, a bag of paper, or other suitable material, is indicated generally at 1. The bag has a bottom 2, sides 3, ends 4, and provides an open mouth 5 at its top. The mouth 5 is here shown as held open by a frame, generally indicated at 6, consisting of sides 7 and ends 8 which lie just within, i..e., just below the top edge of the open mouth 5. The frame 6 is shown as formed of flat strip stock, of substantially greater vertical than horizontal extent. This imparts substantial rigidity to the frame.
Each corner of the frame 6 is shown as receiving the upper end 9 of a leg 10, of which there are four in number, one for each corner of the frame. minate at or below the top border of the frame and are suitably secured within the corners 11 by welding, braz-- ing, or in other simple manner.
The legs 10 as shown extend at right angles with respect to the frame 6 and are parallel to each other. Furthermore, they are tapered throughout their length and should preferably be given a smooth surface finish. The taper and finish assist in enabling the legs to be drawn up out of the garbage or refuse without carrying any of it with them. Preferably, also, the legs should be made of suitable non-corrosive material, or be given a non-corrosive coating, or plating. For hard usage the complete support-legs and frame-should preferably be made of metal, though properly finished wood, or a suitable plastic, would serve the purpose adequately if properly handled.
These legs ter-,
Preferably the bottom ends 12 of the legs should be somewhat rounded as a protection against perforating the bag. Furthermore, the frame 6 and the points of junction of the same with the legs should be as free of obstruction as possible, so as to avoid the catching and retaining of any of the refuse, or garbage, thereon. Normally such bags will not be completely filled with refuse all the way up to the top, for when that is done they become difficult to handle. Hence, the frame 6 rather than being immersed in the refuse, principally serves to maintain the mouth of the bag fully open and provides a rigid base on which small receptacles can be tapped to enable their contents to be discharged into the bag. Thus, the frame 6, rather than extending principally in the var tical direction, as seen in Figures 1 and 2, may well extend principally horizontally as illustrated in Figure 3.
Though the ordinary paper bags which are used for the carrying of groceries and the like can be used in com.- bination with the support of the invention, for they are now being widely used without supports, it it preferable that refuse and garbage bags be of somewhat higher quality. The principal additional feature. to incorporate in the bags is moisture resistance. That can be done either by a treatment of the single shell itself or by providing a lining for the bag. Bags so formed would have inherent in them the toughness required to resist perforation, or tearing, during the application of the support thereto, yet they are obtainable at a low enough price to make them universally acceptable.
In these instances where the support for the bag would normally be in continuous use, the fact that it is rigid and takes up the space required to maintain the bag in fully open position creates no problem from a storage standpoint. In other instances, however, such as when space is at. a minimum and the use of the combination of the invention would be periodic, rather than continuous, collapsibility of the support in a manner to facilitate storage would be desirable. One manner of accomplishing this is shown in Figures 35.
There the frame, shown generally at 15, has its sides minimum when the pivot pin, as indicated at 19, is merely a reduced upward extension of the leg 26. Where the extension 19 commences, the leg 2% is shouldered at 21 providing a seat for the lower of the elements 16 and R7. in the construction here shown, it is the end element 17 which seats on the shoulder.
The maintaining of the pivotal relationship and the securing of the frame elements and legs together is effected by riveting over the end of the extension 19, as shown at 22. Alternatively, that extension can be engaged by some suitable fastening means. Each comer of the support is identical and the legs, save for the pivotal provision at the upper ends thereof, are the same as the legs 10 of Figure 1 and 2. Obviously, the pivotal arrangement shown assures that the legs are maintained in a right angled relationship with respect to the frame 15 while remaining parallel to each other.
From the Figure 4 showing, it will be apparent that in this form of the invention the support need not be maintained as a rectangle, but can be collapsed as a parallelogram. This collapse can be effected to the point where the opposite sides 16 engage each other, thus enabling the stowage of the support in any available long narrow space.
Where, however, the support of Figures 3 and 4 is to be employed in combination with a bag, as shown in Fig 4 ure 1, it would preferably be extended into rectangular formation, since that provides the largest mouth opening for receipt of the refuse. Once placed in desired formation within a suitable bag, the support will be maintained there for the coaction of it with the bag body engaging it will keep it in the position in which it is set while, conversely, the support keeps the bag in expanded position.
Obviously, the support can be removed from the bag in the same manner as that shown in Figure 1 and inserted in the next bag.
A further modification of support is shown at 25 in Figure 6. Here the frame, instead of being made up of four elements, as in the previous forms, is made up of six elements consisting of two long sides 26 and two short end members 27 and 28 at each end. The end members 27 and 28 are pivoted together, as shown at 29, in the middle of each side, while the main corners 30 of the frame are pivoted to the upper ends of the legs 31 in the same manner as shown in Figures 3-5. The end members 27 and 28 are, however, designed to extend outwardly with respect to the corners 30, as the sides 26 are collapsed together for stowage purposes. When, however, the frame is set in position to support a bag, as shown in Figure 1, it is desirable that the members 27 and 23 will not swing inward beyond a straight line po sition. Swinging outward will be precluded by the presence of the bag surrounding the frame, while inward swinging beyond a straight line is precluded in some simple manner, such as by the provision of a suitable wing or extension on one or the other of the arms 27 and 28.
Here again, the legs 31 are of the same formation as those previously described and provide securing or other means at their upper ends. This form of support, when out of the bag can be readily collapsed for storage by extending the pivots 29 outwardly and bringing the sides 26 together.
Though particular formations of legs and frames have been described in the foregoing, it is, of course, to be understood that variations therein can be introduced without departing from the spirit or scope of the invention. The frame has been described as being rectangular, or as having the form of a parallelogram, but it is, of course, contemplated that any shape of open frame in the form of a closed geometric figure, capable of keeping the bag mouth properly open, can be employed. It is further to be noted that though particular provision has been indicated for the securing of the legs to the frames and the providing of pivot pins thereat, such provisions are also subject to modification without departing from the spirit and scope of the invention. Not only these, but other characteristics of the invention may be modified and different embodiments of the invention can be made without departing from the spirit and scope thereof. It is thus intended that all matter contained in the above description, or shown in the accompanying drawing, shall be intended in an illustrative and not in a limiting sense.
