ATTORNEYS RECEPTACLE FOR WASTE MATERIAL This application is a continuation-in-part of US. patent application, Ser. No. 813,477, now abandoned, filed Apr. 4, 1969.

BACKGROUND OF THE INVENTION In todays times, trash disposal is already a world-wide problem and threatens to become more so. Part of this problem is in the space occupied by empty containers such as cardboard boxes, tin cans and bottles. The space so occupied by the average household creates problems in the home itself, particularly crowded apartment houses and residential areas, as well as in the carting of such waste to municipal dumps and in the burying of the waste.

Easy-to-use, convenient, relatively low cost, and fool-proof means are therefore greatly needed to answer these problems.

At many municipal dumps, heavy industrial type compactors are in use. Obviously, these are not suitable for home use. Many towns and cities have trash collecting trucks which attempt to compact the trash as it is collected. These trucks are expensive and the labor associated with their use is also expensive to say nothing of the cost of maintenance.

With the rapid decrease of available free land for public dumps, due to the need for land for dwellings and industry, the burial of uncompacted trash is an inefficient use of the land available. Burning is not an answer, because of air pollution.

Therefore, trash which is fully compacted at the home will answer many of the above problems, provided the means for compaction, and storage pending pick-up by dump trucks, are easy to use, long lasting, and relatively efficient. Operation of the dump trucks will be facilitated, with lessened costs, and more efficient use of land for burial will be obtained.

OBJECTS OF THE INVENTION It is the general purpose and object of this invention, therefore, to provide a composite means for holding trash during compaction, a disposable part of this means being a container removable for holding the compacted trash while awaiting pickup and during transport to the dump.

Another object of the invention is the provision of holder of the above class in which cover means are provided for the insertion of compacting means, the cover being provided with means to prevent the escape of flying glass, etc.

Still another object of the invention is the provision of an inner shield means for preventing the disruption of the disposable container during trash compaction, the shield being readily removable.

A further object of the invention is the provision of a disposable container for trash, or for other articles or materials, which is made from one piece of flexible material in such manner as to provide reinforced handholes at the top, and reinforced sides and bottoms.

Yet another object of the invention is the provision of a container of the above class which is made from a blank by folding and gluing operations, the gluing being done by self-sticking adhesives already present on predetermined surfaces of the blank.

Other objects, purposes and advantages of the invention will be in part obvious from the description which follows, and in part pointed out specifically. I

Throughout the drawings, similar reference characters indicate corresponding parts. Also, throughout the drawings, dimensions of certain of the parts as shown in the drawings may have been modified and/or exaggerated for the purpose of clarity of illustration.

Referring now to FIGS. 1, 2, and 3, there are shown several views of a first embodiment of this invention. It comprises an outer holder indicated generally by numeral 2 having a rectangular cross-section, a bottom 4, front and end walls 6, 8, l0, and 12 and a turned-over lip 14 around the top perimeter. For convenience, although not necessary, the holder 2 should be tapered from top to bottom, as shown, to facilitate nesting holders in storage in warehouses, stores, etc. prior to sale. Holder 2 is made of a strong durable material such as plastic or metal, high density polyethylene being an example of a moldable synthetic resin that is preferable to use, or the holder can be of aluminum or sheet steel.

Fitted over the top of the holder is a cover 16, shaped as a truncated hollow tetrahedron, having the slanting sides 18, 20, 22 and 24. Dependent the inside of each of the'four corners formed between the sides 18-24 is a short L-shaped section 26 of four sections 26 being so positioned as to nest within the comers formed by the walls 6-12, thus assisting in retaining cover 16 in place. Cover 16 may be made of high density polyethylene, the same as holder 2, in which case the sections 26 will be molded as integral parts thereof. If cover 16 is metal, then sections 26 may be fastened thereto by welding or riveting in conventional manner.

Referring to FIGS. 3, 4, and 5, cover 16 is provided with a rectangular aperture defined by edges 30, 32, 34, and 36. A skirt 38 depends from the top of cover 16, and two of the upper edges of the skirt sides are fastened to the cover adjacent the edges 32 and 36, while the other two upper edges of the skirt are attached to the cover back from the opposed edges and 34, thus leaving short lips and 42 as shown. (See FIGS. 1 and 2) The skirt may conveniently be molded as an integral part of cover 16 if the latter is molded, or may be metal (if cover 16 is metal) and attached thereto by riveting or welding. Skirt 38 is long enough so that when the cover 16 is in place on holder 2, the lower rim of the skirt extends below the lip 14.

Each of lips 40 and 42 has notches 44 and 46 therein, respectively, whose purpose is to aid in holding protective cover fingers in place, as will now be described. These notches are shaped with mouths narrower than their interiors.

Referring to FIGS. 6, 7, and 8 (and to FIG. 3 for assembly) with cover 16), there is shown one of a pair of finger guards. Guard 50 as shown is a single piece fabricated construction, made from translucent polyurethane. It has an edge rib 52 provided with a lengthwise channel 54. Channel 54 is interrupted by filled in portions or dividers 56 at two places, these filled-in portions or dividers being shaped with their facing edges 58 slanted toward each other as shown. Dividers 56 are spaced apart slightly less than the separation of notches 44 on the one lip 40 and notches 46 on the other lip 42. When the edge rib 52 (i.e., the channel 54) is slid over the lip 40 or 42, the guard 50 is stretched slightly to align the respective notches and dividers. The dividers will then enter the notches, and the slanting sides of the dividers will retain them in the shaped notches.

' Each of the guards tapers, as shown in FIG. 7, from edge rib 52 to the other edge 60. The guards are slit to provide a plurality of adjacent pairs of fingers 62, each pair being separated by long slits 64 extending from rib 52 to edge 60, and each pair being divided into its two fingers by shorter slits 66. In this manner, a predetermined curvature of the fingers is obtained with the fingers being most flexible toward edge 60 of the guard, and stiffening quickly but continuously and flexibly toward rib 52. (See FIG. 2)

It will be noted that the guards are duplicates, two being used, and that when in lace on cover 16, the fingers overlap. When, therefore, a ram is inserted into the holder and container to crush cans, boxes, and bottles placed therein, the ram can be moved freely in and around the aperture in the cover 16, with the fingers 62 folding flexibly around the ram and overlapping at other places, to prevent any flying glass or other particles from escaping through the cover.

Referring now to FIGS. 9-13, there is first shown the box blank for making the folded box or container 72 of FIG. 10. Blank 70 is formed of corrugated board and comprises the two end walls 74 and 76 joined integrally to the front and back walls 78 and 80, the board being creased or scored at the joints to provide fold lines 82, 84, and 86. At the upper edges of the front and back walls 78 and 80 are respectively attached the flaps 88 and 90, each of these integral with their respectively attached walls. Fold creases or scorings 92 and 94 are provided as shown. lntegrally joined to the flaps 88 and are the end portions 96 and 98, portion 96 being connected integrally with end wall 74 and portion 98 being connected to end wall 76. Fold lines (creases or scorings) 100, 102, 104, 106, and 108 are provided. lntegrally attached to front wall 78 is inner bottom 112, via fold crease or score 114. lntegrally attached to back wall 80 is outer bottom 116, a fold crease or score 118 being provided. Attached integrally to one edge of outer bottom 116 is an end wall reinforcing flap 120, a suitable fold crease or score 122 being provided. The reinforcing end is cut loose from inner bottom 112 and end wall 74 by means of slits 124. Integrally attached to the outer edge of outer bottom 116 is another end wall reinforcing flap 126. Fold crease or score 128 is provided where shown, and end piece 126 is cut loose from end wall 76 by slit 130.

A gluing flap 132 is integrally attached to end portion 98 and end wall 76. A fold crease or score 134 is provided where shown.

Flap 88 is provided with a slot to act as a hand or finger hole, and the upper edge is provided with slots 142. A central notch 144 is provided, and two fold creases or scores 146 are provided extending diagonally across the portion 88 from its lower corners to meet notch 144.

In similar manner, upper portion 90 is provided with handhole slot 150, edge slots 152, central notch 154 and fold creases or scores 156 from the lower comers to the central notch.

Notches 142 and 152 are so dimensionsed as to be the same size as the hand holes 140 and 150. They are positioned on their respective edges so that when the end portions 96 and 98 are bent inwardly and downwardly along fold lines 100, 102, 106, and 104, 134 and 108 to close the container, (see FIG. 13) notches 142 align with slot 140 to form a three-layered hand-hole slot; and similarly notches 152 align with slot 150. At this point, the triangular portions 158 of portion 88 will be flush with the remainder portion 160, and triangular portions 162 will be flush with remainder portion 164. This construction gives greatly added strength to the portions 158-160 and 162-164 for lifting a filled container.

For gluing purposes, it is preferred that the requisite sur faces be coated either with a pressure sensitive adhesive, covered with a sti'ippable protective paper which can be pulled off at the time of assembly. Or, and this is the more suitable structure, the so-called self-sealing adhesives can be used, (often called cohesives) which dry to a non-tacky condition so as to be dry to the touch, and yet two surfaces each coated with such an adhesive will bond to each other. The particular surface adhesive is not a part of this invention, and selection of the proper kind is within the skill of the art.

If the cohesive type is used, then the following surfaces of the blank of FIG. 9 will be coated. (Assume that as viewed in FIG. 9 the viewed surface of the drawing is hereinafter called the front surface of any portion, and the back of the drawing sheet is called the back surface.)

The following front surfaces will be coated: 120, 116, 126, flap 132, portions 88 and 90, and the top edge portion of cover portion 96, (where it overlaps cover portion 98 to seal the container).

The back surfaces which will be coated are: 76, 74, 112, I

(those edge parts of wall 78 and portion 88 which the flap 132 will overlie) and the top edge of cover portion 98 which will underlie the edge of cover 96.

Thus, the following advantages will be noted with respect to the container 72: For strength, it has a double bottom and double end walls. When used, it is first in its fully opened position shown in FIG. 10, but when filled to the level of fold lines 92, 94, 106, and 108, the cover portions 96 and 98 can be folded inwardly and downwardly, their edges overlapping for sealing; while at the same time the triangular portions 158 and 162 join, respectively portions and 164 to provide added strength to these portions and reinforce the hand holes. Furthermore, individual sealed containers can be stacked one on top of each other merely by bending the portions 160 and 164 outwardly, or inwardly to lie one on top of each other.

Referring now to FIGS. 14, 15, and 16, a removable and reusable shield, or liner is shown. This comprises a rectangular, hollow tube molded of a strong, tough synthetic plastic such as Noryl, the trade name of a polyphenylene oxide, or Lexan, the trade name of a polycarbonate, both of these materials being available from General Electric Company. It has a shape similar to that of the container 72, but it is smaller so that it will fit therein. The liner 170 comprises the four walls 172, 174, 176, and 178 and is open at both ends. It has a hand hold 180 at the top. It is to be noted that the liner or shield tapers from top to bottom, being larger at the bottom than the top. The taper found suitable is about l-3 to the vertical to facilitate nesting liners in storage warehouses, stores, etc.

A flange 182 projects outwardly from the bottom edge of the liner, the outside dimensions of this flange being such as to fit nicely within container 72. The flange thus spaces the bottom of the liner in the container. An inwardly extending lip 184 is provided at the top edge of the liner, so dimensioned that the skirt 38 will fit nicely down past the lip edges (see FIG. 1 Thus, the lip serves (together with skirt 38 and cover 16) to space the liner centrally at the top of the open contamer.

Instead of the liner 170, a second embodiment 190 thereof (and therefore a second embodiment of the invention) is shown. Again, it is a tapered, rectangularly shaped, molded tube, having the walls 192, 194, 196, and 198. The tube is tapered, as shown, being larger at the bottom than at the top. A lip 200 extends outwardly to facilitate lifting the liner and/or withdrawing it from a filled container. It also reinforces the top of the liner. (See FIGS. 17, 18 and 19.)

In this embodiment, the liner is also reinforced laterally and longitudinally by a plurality of circumferential ribs 202 and 204, and a plurality of vertical ribs 206 and 208, ribs 206 being on the end walls, and ribs 208 being on the front and back walls. These several ribs also serve to space the liner inside the container. The dimensions of the top of the liner are such that skirt 38 fits nicely down inside its top. As in the other liner, approximately at l-3 taper to the vertical has been found to work satisfactorily.

Referring to FIG. 20, another form or embodiment of the guard 50 is shown. In this instance the guard comprises a main sheet portion 212 which is slit to provide fingers just the same as the fingers 62 are provided in FIG. 6. The back edge portion of sheet 212 is solid, and to the top and bottom surfaces of it are fastened, by means of a suitable adhesive, the top and bottom reinforcing layers 210. Layers 210 extend beyond the rear edge of sheet 212 in order to provide a channel similar to the channel 54 of FIG. 6 and for the same purpose. Two dividers 214, similar to dividers 56, are provided on the back edge of sheet 212 to enter notches 44, as in the case of the FIG. 6 form of guard.

To use the system, a container 72 is placed in the holder 2, the liner 170 is placed in the container, and then the cover 16 is placed over both, sections 26 fitting down into the holder to guide and centralize the cover in position, and skirt 38 fitting into the liner as described above. As thus assembled, it will be noted that the upright portions 88, 90, 96, and 98 of the container extend well up into the cover, so that the aperture of the cover overlies the open top of the container. Also, the skirt 38 fits down into the top of the container.

When thus assembled, a can or bottle to be crushed is put into the container, passing readily through the flexible fingers 62. A ram is then thrust into the enclosure and the can or bottle is crushed by repeated blows. Successively, other waste cans, tins, bottles, boxes, etc. may be crushed or compacted.

As this continues, it will be noted that the lateral resultant of forces occurred in compaction are exerted against the liner 170 and not against the sides of the container 72. This prevents these forces from rupturing the walls of the container, and thus is able to resist compacting forces.

When the container is filled with compacted trash up to the above specified horizontal fold lines, or even some distance above, the liner 170 is withdrawn. The negative draft given to the walls facilitate this withdrawal. Upon withdrawal, the compacted trash can now spread sideways, thus lowering the level of the top of the trash down to, at least, the fold lines of the top closure portions.

The container is withdrawn, and the top is sealed as shown in FIG. 13. The sealed container is now stored to await collection by a dump truck.

Referring now to FIGS. 21-28, there is shown yet another embodiment of the invention.

As before, a holder comprising a base 220, and a cover 222 are provided each of which will now be described. The base 220 is made, preferably, of high density polyethylene or other strong, tough, synthetic plastic, but it could be made of a metal such as steel or stainless steel. The base has at its top the outwardly turned lip or flange 224 which, as will be described below, serves the function of providing a seat for an inside liner as well as strengthening the top portion of the base. As before, the base has a bottom 226. Preferably, the base has a slight taper as shown.

The lid 222 is, as before, a four-sided, open-ended shell having the downwardly tapering sides 228 from which depend a skirt 230 adapted, as shown and as will be described below, to fit over (full lines in FIG. 23) or within (dotted lines 229 in FIG. 23) a skirt upturned at the end of an inner liner. The cover is provided at the top with an opening 232 from which depend the two interior shields 234, one at each end of the opening. Mounted across the upper lips forming the opening 232 are the pair of flexible finger structures 236 each of which is constructed the same, and as shown in FIGS. 26-28, comprises a comb-like structure having a back 238 anda plurality of closely adjacent but separate fingers 240. The material of the finger structures 236 is flexible, tough, elastomerlike material such as Neoprene or the equivalent, or can be made of a flexible plasticized synthetic resin if desired. The cuts in structure are, as in the previous embodiments, so made that one cut 242 is shorter than its adjacent cut 244 so that both a sufficient degree of flexibility of the fingers will be provided and also to reduce the tendency of adjacent fingers to cross over each other. The finger structures are attached to the rim conventionally, by providing a metal clamp strip 246 lying over the back portions of each finger assembly, and then through suitable holes in the strips 246, the back portions of the finger structures and the lip 235 of the cover, rivets are inserted and headed over to fasten the finger elements so that the fingers thereof overlap. As before, by this means and in conjunction with the shields 234, entrance into the inside of the outer holder is provided through the flexible fingers 240, and these fingers are sufficiently flexible to close around the shaft of the instrument used to compact rubbish within the interior of the holder. At the same time, chips are prevented from flying outside of the container.

The entire cover 222 is made of a strong material such as Lexan previously described, or its equivalent. At least a portion of the cover 222 needs to be at least translucent, and preferably transparent, in order to see the interior of the receptacle to facilitate compacting rubbish and trash therein.

As in the previous embodiments, an inner container 72 is provided, made and put together as is the inner container 72 shown in FIGS. 10-13 from the blank shown in FIG. 9. Since the container for this embodiment is the same as that previously shown, no further description will be given at this point.

However, the liner of this embodiment is different from the liner previously shown. The liner of this embodiment (FIGS. 21 and 22), indicated generally by numeral 250, is a two-piece assembly having an upper piece 252 and a lower piece 254. While a mold could be made for molding this two-piece assembly as a one-piece unit, nevertheless, such a mold would be relatively expensive and for this reason the preferred embodiment shown and described is presented.

The draft of the top portion 252 is positive (as used in this application to mean that the liner is slightly smaller in crosssection at its bottom portion 256 than it is at the upper end 258 of the upper liner). Contrary-wise, the portion 254 has a negative draft as shown. That is, the bottom end 260 of this bottom portion is larger in cross-section than the cross-section of the upper end 262.

In this embodiment, as previously, the liner is rectangular in cross-section and the bottom end 256 and upper end 262 of the respective pieces are so sized that end 256 fits snugly down into the end 262. When once in place, these end portions are held together securely by means of the bolts 264. In view of the nature of the drafts, a reference to FIG. 23 will indicate that the corner portions of the upper end 262 of the bottom portion 254 of the liner are preferably relieved to make it easier to fit the respective ends together.

Referring now to FIGS. 21 and 23, the uppermost end portion of the top piece 252 of the liner flares outwardly to form a funnel portion 268, and the upper edge of the funnel portion first extends outwardly to form the flat flange portion 270 and then turns upwardly to form the skirt 272. The flare of the funnel portion 268 is sufficient to permit the assembled liner to drop down into the container 72 to come to rest approximately on the bottom thereof, at which point the flange 270 will lie against the outwardly extending flange 224 on the top of the holder base 220. On each of opposite sides of the flange 270 is mounted a post 274 of conventional nature, the post being' riveted as shown in FIG. 24 to the flange 270. See FIGS. 23 and 24. A reinforcing plate of steel or tough plastic 276 is preferably provided on the top of flange 270 in each instance, this plate being fastened to flange 270 by means of the rivets 278. Post 274 is provided with a suitable shouldered structure as illustrated in FIG. 24, so that when the end of the post is riveted over as at 280, the post will be securely fastened to the flange 270.

The post 274 is provided with the peripheral groove 282 and a head 284. Provided in the flange 224 of holder base 220 is a hole 286 sized to receive the post 274 and the head 284. A reinforcing plate 288 is fastened to the underside of the flange 224 by means of the rivets 290 in conventional manner. Pivoted to the plate 288 is the finger-latch 292, pivoting being done by a properly shouldered stud 294. A suitable spring retaining finger 296 projects downwardly from the plate 288 as shown, and one end of a spring 298 is held in the finger 296. The spring takes a turn around the shank of the pivot stud or post 294, and the other end is retained in a suitable finger 300 on the latch plate 292. As viewed in FIG. 25, the spring 298 biases the latch plate 292 counterclockwise about its mounting post 294. A recess 302 is provided extending inwardly of latch 292, this recess being sized to permit the latch to enter the groove 282 to lock the post 274 in the hole 286. A conventional stop pin 304 is mounted to the plate 288 in order to maintain the latch plate 292 in proper position, when the latter is not engaging the post 274.

By this means, the liner is detachably lockedto the top of the outer holder. The purpose of this is to prevent the liner from rising upwardly due to the negative draft of the bottom portion 254, when material is being compacted within the liner.

On two sides of the funnel portions of the upper part of the liner 268 are provided, if desired, a pair of handles 310.

The operation of this last embodiment is similar to the previous one, in that to assemble the device, a container 72 is first prepared in accordance with the instructions given above, and is then inserted in the outer holder 220. The liner 250 is assembled by fastening the portions 252, 254 together. The assembled liner is then inserted into the container 72 and comes to rest with the outer flange 270 resting against the flange 224, as shown in F IGS. 21 and 23. In this position, posts 274 will each have extended through its respective hole 286 as described above, and the latch plates 292 will have engaged into the recesses 282 to lock the liner 250 securely to the holder 220. The cover 222 is then placed over the upstanding skirt 272 of the liner. (If desired, the cover 222 may be of such cross-sectional size and shape that the downwardly extending skirt 230 fits easily but not too loosely inside the upstanding skirt 272.) It will be found that the cover is of sufficient weight and should be of a close enough fit so as to retain itself in position on the holder 220. In this assembled position, the fingers 240 and 242 will now overlie the liner 250 and also inner container 72, and when trash is put into the receptacle through the opening 232, it will fall into the container. At that time, the compacting means described above may be used to flatten down and pack together the trash.

When the compacted trash has reached about the level of the reinforcing sides 126, the cover 222 is removed, and the latch plates 292 are swung outwardly to release the latch posts 274. The inner liner can then be withdrawn, the negative draft on the bottom portion 254 facilitating this withdrawal. Thereafter, the container 72 may be removed, carrying with it the compacted trash. The container top may then be folded down for storage first (if desired) and later disposal.

Thereafter, a new container 72 is prepared and placed in the outer holder 220. The liner 250 is placed down within the container as described above, and the catches are snapped in place. The cover 222 is then placed on top of the skirt of the liner and the device is again ready to have trash compacted therein.

As in the previous embodiments, it is the liner that makes the embodiment practical and efiective. Without the liner, the outward force exerted by the trash as it is being compacted would rupture the sidewalls of the container. if the container, in an attempt to prevent this, is made a close fit against the inside walls of the outer holder 220, it will be found that the outward force of compaction will jam the walls of the container against the walls of the holder to the extent that it will be dif ficult to pull the container from the holder. Thus, the liner serves the very definite function of protecting the walls of the container from rupture during compaction of the trash, and to facilitate easy removal of the container. Also, the liner is so shaped that it may be easily withdrawn (due to its negative draft) from the container when the proper level of compacted trash is reached. The instant liner is also advantageous in that because of the two drafts, it will be found possible for the store owner (or the warehouse or distributor) to stack the separate parts to occupy a minimum of space, as compared to a liner which is all one piece. The reliefs 266 at the upper corners of the bottom portion 254 of the liner, will also assist in such stacking. I

It is obvious that from the above, the liner must be of a strong material, and preferably is made of a strong tough plastic such as Noryl (trademark of General Electric Company) which is a synthetic resin of the modified phenylene oxide type. Or, if desired, it could be made of steel or other strong metal. However, it will be found that there are suitable plastics on the market such as that mentioned above, which will be entirely suitable for the purpose. If desired, the top and bottom halves of the liner may be of different materials. For example, the bottom half may be of the above-mentioned Noryl material and the top half may be of a high density polyethylene or other equivalent material. The reason for thus distinguishing the two parts of the liner is that it is the bottom half which takes the force of compaction in a lateral direction, and not the top half.

It has already been mentioned that the fit of the downwardly extending skirt 230 of the top of the device should be preferably a snug fit over or within the upstanding skirt 27 2 of the upper end of the liner. It is pointed out that this fit is not critical.

The end shields 234 are shown as integral molded parts of the top 222. Of course, if desired, these end shields could be made separately and attached to the top by suitable rivets, etc. The integral molded construction is, however, the preferred one.

in view of the above it will be seen that the several objects of the invention are achieved and other advantageous results attained.
