Lindholm, 8514 W. 119th Place, Palos Park, Ill. 60464, and Donald W. Lindholm, 15929 S. Grove, Oak Forest, Iii. 60452 Filed June 8, 1966, Ser. No. 556,164 12 Claims. (Cl. 232-432) The present invention relates to a bag-lined receptacle of the type that may be used to receive garbage. A baglined garbage receptacle of the type herein disclosed may be used in the kitchen of a household where it will provide support for the side walls of a paper garbage bag to prevent tipping or spilling from such a bag. When the garbage bag so supported is filled, the receptacle may be easily removed to the place of disposal and the garbage containing bag easily deposited there without the user handling the bag itself.
A feature of this invention is the provision of a split rigid container adapted to be lined with a conventional grocery and produce paper bag in which garbage can be packed and pressed tightly to fill the bag without resulting in bursting or tearing of the bag and adapted to be easily opened and expanded to release the packed bag without damage.
It is a general object of the present invention to provide a new and improved bag-lined garbage receptacle which may be used as described above or in similar uses.
It is a more specific object of the invention to provide such a receptacle which is easy and economical to use, assemble and manufacture.
It is one object of the invention to provide a receptacle which can discharge a bag and its contents without the necessity of handling the bag itself.
It is a specific object of the invention to provide such a container which will not jam in discharging its contents even if irregular or oversized items are placed therein.
In accomplishing these and other objects of the invention a receptacle is provided which is adapted to receive a bag and support it in an open upright position to receive material introduced through the top of the receptacle and to discharge the filled bag through the bottom of the receptacle. The receptacle comprises a pivotally connected complementary member defining an open-ended tube in closed position adapted to swing to an open position providing an enlarged space therebetween, and a lid selectively closing the top of the tube and the bottom. Means are further provided for selectively locking the bottom in a closed position, whereby a bag introduced through the top of the closed lockedtogether members may rest in the bottom completely enveloped by the members in a supporting upright position lining the tube defined thereby to receive material through the top thereof and may easily be discharged through the bottom by unlocking the members and by swinging the members to an open position.

As shown on the drawings:
Referring now to FIG. 1 there is depicted a receptacle adapted to receive and support a bag containing garbage or the like. The receptacle, which is generally indicated by the numeral 10, comprises pivotally connected complementary members 11 and 12 defining an open-ended tube when in a closed position, as shown. The member 11 comprises a rectangular front wall 11a and rectangular side walls 11b formed at the longitudinal end edges thereof as part of a unitary structure for enclosing three sides of a rectangular tube. The member 12 completes the tube with a rectangular back side wall 12a, best shown in FIG. 2. In addition to the back side wall 12a, the member 12 includes a pair of oppositely disposed triangular-shaped wall segments 12b which overlap for a portion on the outer surface of the walls 11b of the member 11 and include a pivot mounting 13 defined ,therebetween. The side walls 121; are in the shape of a right triangle with the base along the edge of the back wall 12a and the altitude adjacent to the top edge of the wall 11b. Selectively closing the top of the tube formed by the members 11 and 12 is a lid 14 of a generally rectangular configuration sized to fit over the generally rectangular cross-sectional end of the tube and pivotally mounted at 14a to the member 12 along the upper edge of the back wall 12a. The members 11 and 12 are of such a size and configuration as to receive therein a conventionally sized paper bag or sack of the type commonly used in super markets for the packaging of groceries and thus are commonly available to the housewife. Such bags are often used independently of a receptacle for holding garbage in the kitchen. When so used, they are easily upset and garbage placed therein often soaks through the paper and spills or causes the bag to tear and thus spill the contents at an inconvenient location. The receptacle 10 is sized so as to support such a bag and maintain it until the transportation of the bag and the garbage contained therein to a suitable disposal area may be achieved. The lid 14 includes an outstanding lifting handle 15 placed on the front edge 14b and similar handles 15 formed on the transverse edges of the lid.
A carrying handle 30 is provided for the receptacle 10 of a generally squared C-shape for fiitting about the outer surfaces of the sections of the receptacle. The handle is attached at the point 30a on each side wall 111; to the exterior plate 31 formed for receiving it. The receiving metal plates or hinge fittings 31 are preferably welded to and depend downward from a wire 22 at the transverse center point of the walls 11b. The fittings 31 extend through a cutout portion of the plastic encasement of the wire 22 and are positioned outside of the walls 11b to prevent any contact between the metal fitting 21 and interior of the receptacle ll).
The receptacle 10 is further provided with a base 16 of generally rectangular conforming configuration for closing the bottom of the tube formed by the members 11 and 12. The base 16 includes means 17 for selectively locking the base to the members 11 and 12. The locking means 17 is affixed at the front longitudinal edge of the base 16 between that edge and the portion of the front wall 114; of the member 11. The base 16 is pivotally mounted to the rear wall 12a of the member 12 along its bottom edge 12a, as shown in FIG. 2, by means of a pair of spaced hinges 16a and 16b. The members 11 and 12, the lid 14, the base 16 and the locking means 17 are preferably formed of a flexible plastic material such as polyethylene or stiff rubber and reinforced by a plurality of wire or rod sections. Although other construction materials may be used such as wood or light metal, the more flexible materials are preferred. The receptacle formed from the preferred material is not only light in weight and easy to assemble but is also easily cleaned. It should be no d at y P a tic p ts a e xp e to the s i the present embodiment and that any leakage may be easily wiped or hosed off at the time of discharging the bag from the receptacle. The member 12 is reinforced by a thin rod or stiff wire 18 of circular cross section. The wire 18 generally encircles the periphery of the member 12 extending along the hypotenuse and altitude sides of the triangular walls 12b and across the top and bottom of the wall 121;. The wire 18 is encased in and surrounded 'by the flexible material of the walls for most of its extent bu is n so n ased a ong the lower e o wall 12 Th ab s i to rece e he ex n i p s 164 and 16b of the base 16 which cooperate with the wire 18 to form the pivotal connection between the base 16 and the member 12.

Similarly a slight pressure uponthe flexible material of the member 17 will replace and relock the members to,- gether. It has been found'that this simple lock is suff cient and provides adequate security to hold the base to the members 11 and to hold together the members 11 and 12.
This lock 17 actually holds more securely with the increasing load as the receptacle is filled. The base 16 is preferably hinged by the hinges 16a and 16b and is made with a conformin-gly shapedsnap-on provision of a C.- opening 16b similar to that described above in conjunction with the lid 14 and hinges 14a, with the hinges being flexible and easily placedon'thc wire 18 during assembly. The base 16 is formed in the shape of a shallow dish, opening upward so as to be able to entrap any liquid seep.- age therein to lessen the chance of spillage or leakage from the receptacle 10. The forward part, as indicated at 162 is sloped to facilitate the discharge of the bag 22.
from the receptacle 10. The junction between the base 16 and the members 11 and 12 may be made tight fitting and substantially leak-proof. The rim of the base 1.6, as indicated at 16), encases the bottom edge of the member .11 to prevent bulging of this member when the bag is ll W h arbage or the like;
In F G- the coope ation be ween th as 2 the bag holder 20 is shown. One of the side wall holders is shown in its open position as in preparation for the insertion of the bag 23. When open,'the bag holder 20 has s upp r Po t est n a a ns h h suppo t 8 a t side wall 12b so as to be clear of the opening formed by the uppe o s s o he m mber 1 an 2- T ssb 10, with the lid 14 upraised and resting against the wire portion 131:, is in position to receive garbage placed here n- Th h s 2.

The pivots 13 between the members 11 and 12 are formed in a unique manner so as to facilitate assembly;
A-s best shown in FIG. .8, the walls 12b are each formed with a continuous projection in the shape ,of a cone-section tapering outwardly with an expanding diameter from the wall 12b. The section 13a of the wall 12b is formed with a hole 13b of conforming shape and size, i.e., of
increasing diameter from without through the interior of the wall 12b. As the members 11 and 12 are, as men tioned above, preferably made of flexible material such --"as polyethylene, the assembly of the portions is made easily and quickly as the walls may simply be pressed together to allow the outstanding portion 13a to enter the hole 13b, and be captivated therein.
As depicted in FIG. 9, the members 11 and 12 are so constructed as to open upon release of the locking means 17 so that the base 16 may swing away, and any bag such as the bag 23, indicated in dashed outline in FIG. 9, may fall clear therefrom. With the receptacle 10 supported by the handle 30:: at approximately its center of gravity, at the release of the locking means 17 the downward pull of gravity causes the base 16 to pivot about the pivots 16a and 16b and swing downward. Also the member 12 is caused to pivot about the pivots 13 and swing away from the member 11. This also causes the member 11 to move slightly outward pivoting about the handle supports 30a thus moving the forward wall 11a from the bag 23. The bag 23 drops quickly out of contact with the bag holders 20 since there is but frictional support of the bags between the members 20 and the bag 22. In some uses, it is desirable to remove the holders 20 from the bag 23 and to close the bag within the receptacle prior to the release operation depicted in FIGS. 9 and 10. In which case, of course, a closed bag would be discharged from the bottom of the garbage receptacle 10.
As best shown in FIG. 10, the wall 12a at the bottom of the base member has an outstanding lip portion 12k for the prevention of leakage from the bag and for aid in release of the bag from the member 12. The bottom and top rear edge corners of the side walls 11b are cut off at 11k to accommodate the lip portion 12k and the top, as shown in FIG. at 11b, to allow the member 12 to pivot freely.
It should be noted that with the base 16 released and swung away, the bag 23 is surrounded on three sides by the un-reinforced walls 11a and 11b of the member 11. These walls being preferably constructed of flexible material offer little resistance to the discharge of the bag and its contents even if the contents be of irregular shapes such as would normally resist discharge. The unreinforced side walls 11b being of flexible material allow behavior, at least in part, as if they were free, to expand outwardly from the bag 23. Thus, the bag 23 is effectively freed of all the supporting walls of the members 11 and 12 during the discharge operation.
It should further be noted that, in returning the receptacle to its closed position, the side walls 12a of the member 12 function to automatically align the walls 11b of the member 11 and to reinforce them.
As will now be apparent a receptacle for garbage and the like has been provided which is both economical to manufacture and easy to use. The receptacle It) by providing a splitting or opening between its members prevents the jamming of the bag-receiving tube by large or irregularly shaped items and facilitates the easy ejection of the bag and its contents without the necessity of handling the garbage bag itself.
