ORIGINAL

COMPLETE SPECIFICATION STANDARD PATENT Invention Title: Waste receptacle The following statement is a full description of this invention including the best method of performing it known to us:- FIELD AND BACKGROUND OF THE INVENTION The present invention relates to a waste receptacle. More particularly, the invention is concerned with providing a waste receptacle wherein a fresh plastic 5 garbage bag appears therein automatically upon the removal for disposal of a full bag.

9 o• In developed countries where there is concern for keeping a clean, tidy and healthy home and environment, no more ubiquitous article than the waste receptacle exists. No home, office, factory or public building; no public garden, recreation area or nature reserve will be kept clean without a number of receptacles wherein people can dispose of the innumerable waste items which are generated as a result of eating, drinking, smoking and other day-to-day activities. Waste receptacles are therefore manufactured and distributed to suit all conceivable needs, ranging in size from about one liter for use in cars and taxis, up to the 56-gallon (215 liter) size found in factories and large public kitchens.

The need for a waste receptacle is particularly felt where the waste generated is of a moist nature, such as in kitchens, or when the waste is contaminating or hazardous, such as waste from hospitals. It is, therefore, a

common practice to line the inner faces of a waste bin with a plastic bag. Such bags are often made of low-density polyethylene or linear low-density polyethylene, and are manufactured and sold in packages of individually-cut bags, or in the form of rolls. Preferably, a convenient way to store such a role of bags 5 would be in a roll of bags which is formed by a long, cylindrical, usually folded, flexible extrusion or sheet of bags. The length of the extrusion or sheet of bags is preferably partially subdivided by a pair of adjacent transverse lines every 50 to 100 centimeters, a first solid line serving to seal the base of one bag and a second, adjacent perforated line providing a convenient tear line for separating and opening 10 the next bag.

It is common experience that changing a full garbage bag involves the following steps; removal of the full bag from the waste bin, and disposal thereof; going to the location where new garbage bags are stored, separating and taking a single bag; going back to the location of the waste bin; if necessary, removing garbage which has meanwhile been deposited in the unlined receptacle; 0 opening the new bag, which is often surprisingly difficult, as it is frequently difficult to identify which side of the bag has to be opened; and fitting the new bag in the waste bin and folding the upper edge of the new bag over the rim of the waste bin.

In general, the overall tediousness of the above list, renders it understandable why individuals are not overly eager to perform such tasks.

5 If the tasks were rendered easier, individuals would more readily agree to carry them out. It may also be noted that, in particular circumstances, the time expended in servicing waste receptacles is neither trivial nor unpaid.

For example, cleaning personnel in a large public park or zoo may spend the major part of their time on servicing waste receptacles.

10 Dispensers for rolls of plastic bags are known, but the dispensers do e little to alleviate the task of changing a full bag of waste, placing the new bag in the waste bin and the like, as described hereinabove.

It is therefore one of the objects of the present invention to obviate the disadvantages of the prior art waste receptacles, and to provide a waste receptacle which is easily and conveniently provided with a fresh plastic bag immediately upon the removal of a bag that the user wishes to replace. Such a decision may be prompted by a bag becoming heavy or having a significant quantity of refuse therein. Alternatively such a decision may be prompted by a failure of the bag being defective or any other reason due to which the user elects to replace the bag presently used.

4~r DESCRIPTION OF THE PREFERRED

EMBODIMENTS

The present invention is of a waste receptacle for the disposal of waste by providing a waste receptacle wherein a fresh plastic garbage bag appears therein automatically upon the removal for disposal of a bag which has become heavy or has a significant quantity of refuse therein or any other reason deemed sufficient by the user.

The principles and operation of a waste receptacle according to the present invention may be better understood with reference to the drawings and the accompanying description.

With specific reference to the figures in detail, it is stressed that the particulars shown herein are by way of example only and for purposes of illustrative discussion of the preferred embodiments of the present invention, and are only presented in the course of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to an ordinary artisan skilled in the art how several forms of the invention may be embodied in 10 practice.

Referring now to the drawings, there is shown in Figure 1 a first embodiment of a waste receptacle 27 for collecting a quantity of waste material 41.

Waste receptacle 27 includes a hollow container 42 having a length and a width featuring a substantially elongated aperture 50, having an outer edge 137, formed in a lower surface 74 of container 42 and aperture 50 communicating with a cavity 138 in hollow container 42, container 42 having an entry facing vertically.

Waste receptacle 27 also includes a base unit 31 situated beneath container 42 and having a recess 28 formed in base unit 31 for situating a plurality of interconnected bags 46. A convenient form of dispensing and storing bags 46 is by placing bags 46 in recess 28 is when bags 46 are arranged in the shape of a roll 45. When bags 46 are in the shape of roll 45, recess 28 revolvably retains roll 45 of connected plastic garbage disposal bags 46 with ease.

In another embodiment (not shown), recess 28 is arranged to accommodate a number of rolls 45 in addition to roll 45 in use.

Bags 46 are typically made of low density polyethylene or linear lowdensity polyethylene. Roll 45 includes a long, cylindrical, folded, flexible 5 extrusion, its length partially subdivided by a pair of adjacent transverse lines 48 every 50 to 100 centimeters. The first line (not shown) is a solid, heat-sealed seam serving to seal the base of each bag. The second line (not shown) is a perforated line adjacent to the first line and provides a convenient tear line for separating and opening the next bag thereafter.

10 Aperture 50 formed in container 42 allows passage of a line of connected bags 46 from roll 45 to the inner volume of container 42. After withdrawing and :i then separating a full bag 46f from an adjacent bag 46a, the user need only fold an open edge 52 of bag 46a over a rim 29 of container 42, thereby rendering new bag 46a ready for use.

Base unit 31 preferably includes a gripping surface 71 attached thereto, or integrally formed therewith. Gripping surface 71 is accommodated by aperture fonned in holder 28 and grips sheet of bags 46 when the user displaces container 42 by applying pressure, preferably with his foot, on a pedal 73. Container 42 is properly aligned in relation to base unit 31 using a guide Receptacle 27 may be molded of polyethylene, polypropylene, or a similar material. For larger sizes, a structural plastic foam is preferable. Preferably, those receptacles 27 used outdoors, are substantially made of metal, or plastic containing an ultraviolet stabilizer thereby protecting the plastic against sunlight degradation, wherein the word substantially, in this context, implies most elements of the receptacle 27 are made of metal or the aforementioned plastic variants.

A second embodiment of the invention is shown in Figure 2, wherein a 5 second receptacle 30 is provided with a bag locking mechanism 32. Bag locking mechanism 32 is operated by the user in order to grip bag 46 adjacent to bag 46u in use. Bag locking mechanism 32 shown in Figure 2 is designed to be operated by the user's foot, thereby leaving his hands free to grip, tension and separate bag 46u, from roll 45 once bag 46u is replete with refuse.

10 As shown in Figure 2, bag locking mechanism 32 includes a foot-operable lever 34, pivotally attached to receptacle 30 at 47 and including a gripping element .i 36. Foot pressure on lever 34 results in element 36 pressing bag 46 against a securing surface 38 of receptacle 30, thereby enabling the easy separation of bag 46 from adjacent bag 46u.

Roll 45 is situated in a roll holder 40 which holder 40 is provided with an upper opening 53, for the convenient replacement of a new roll 45 (not shown) once the user wishes to replace roll 45 which may occur upon the partial and/or total depletion of roll 45 being used.

Shown in Figure 3 is a third embodiment of the present invention, wherein a waste receptacle 44 is shown with a user-operable securing mechanism 49, for temporarily preventing roll 45 revolving. As explained hereinabove, the securing of roll 45 facilitates handling a full garbage bag 46 which then may be conveniently gripped, tensioned and separated fiom adjacent bag 46u. Waste receptacle 44 further includes a gripping element 130 attached to, or integrally formed with a foot pedal 51. Pedal 51 is also attached to, or integrally formed with, a lever 55, pivoted at 59. Applying an appropriate degree of pressure on pedal 51 renders roll momentarily unrevolvable for as long as the pressure on roll 45 persists.

SSuspending receptacle 44 is best achieved, according to this embodiment, by using a bracket 132 placed in a vertical surface such as a wall 54 and designed to accept a catch 134 attached to, or integrally formed with receptacle 44. Receptacle 44 as shown in Figure 3, is adapted enabling suspension of receptacle 44 from vertical 10 surface 54.

Figure 4 shows a fourth embodiment of a waste receptacle 56. In this embodiment a roll holder 58 retaining roll 45 is positioned withm a waste-receiving container 60. Loading of a new roll 45 is achieved by placing roll 45 axially through an aperture 62 formed in container 60. This construction is less likely to attract thieves, tamperers or vandals, and thus is well-suited to use in public areas.

Figure 5 depicts a fifth, especially preferred, embodiment of the present invention. A receptacle 64, similar to receptacle 27 as described hereinabove, is provided with a base unit 66, which supports a waste container 68 which container 68 is similar to container 42 described hereinabove and shown in Figure 1. Base unit 66 is equipped with a bag holder 69 for holding roll 45 in place. Base unit 66 includes a projection 71, which projection 71 is designed to be accommodated by aperture 72 fonned in bottom surface 74. When projection 71 is accepted by aperture 72, projection 71 then engages bottom surface 74 allowing ready detachment of bag 46a from bag 46u. Projection 71 is designed to create a sufficient margin between itself and aperture 72 formed in bottom surface 74 to 5 allow passage of bag 46a pursuant to the user pulling bag 46u, thereby allowing bag 46a to enter container 68. Aperture 72 formed in bottom surface 74 is further preferably formed with at least one, and preferably two as shown, upraised lip 67, such that any leakage from refuse in bag 46u is contained in container 68 and does not soil base unit 66 and/or recession 69. Container 68 is guided at a guide 75 to 10 rest on top of base unit 66, and may be readily displaced for the purposes of cleaning and/or loading of a new roll A sixth embodiment is shown in Figure 6, wherein a waste container 80 is provided with a hinge 82 proximal to a base unit 78 situated beneath container Container 80 further includes a receptacle 76 similar to receptacle 64 shown in Figure 5 and described hereinabove as well as a recession 88 situated between bottom surface 74 of container 68 and a lower surface 70 of base unit 78. Due to the partial acceptance of roll 45 in recession 88 and the lower half of roll 45 resting in base unit 78, base unit 78 may be rendered lower than base unit 66 in Figure thus economizing on the overall size and space used for container 80. In order to successfully reload bag holder 88 with a new roll 45, container 80 is displaced sufficiently, by pivoting container 80 about hinge 82 until roll 45 may be readily accepted in holder 88. Alternatively, an urging mechanism or bias (not shown) can be provided for displacing container 80 back towards base unit 86 about hinge 82, and even to provide the force needed for gripping the sheet of bags 46 and enabling easy detachment of bag 46a from bag 4 6 u, eliminating the need for foot pedal 73 shown in Figure 1.

Figures 7 and 8 show a seventh preferred embodiment including a container 80. Similarly to previously shown embodiments, container 80 rests on base unit 31, which base unit 31 includes a holder 28 similar to holder 28 in Figure 1. Likewise, contaier 80 may be displaced from base unit 31 for the purpose of loading and/or 10 replacing roll 45 (not shown). Also similarly, container 80 includes aperture 72 formed therein as well as gripping surface 71. Container 80, further includes at least one, and preferably two as shown, resilient grippers 77 attached to, or integrally formed with, outer edge 137 of aperture 72 formed in container Grippers 77 act to seal aperture 72 preventing any refuse or fluids from seeping and/or entering into base unit 31 or holder 28.

Preferably, grippers 77 are made of rubber, silicon or a different material having the same properties.

Yet another configuration is shown in Figure 9, wherein a similar container 80 including gripping surface 71 attached to base unit 31, which base unit 31 further includes at least one, two are shown, transverse bands 79 such that when container 80 is pivoted about hinge 82 thereby making aperture 72 accept surface 71 with bands 79 resulting in the application of a degree of pressure between bands 79 and aperture 72 sufficient to secure container 80 to base unit 31.

Bands 79 are used for preventing the inadvertent displacement of bags 46 as well as bands 79 potentially also serving to provide the force needed for 5 gripping the sheet of bags 46 (not shown) to allow the ready detachment of bag S. 46a (not shown) from bag 46u (not shown), thereby eliminating the need for foot pedal 73 (not shown).

Preferably, bands 79 are made of a resilient material such as rubber.

More preferably, container 80 further includes a rim 94 for easier securing of bag 46a (not shown) being used.

Turning to Figure 10, there is shown a cross-sectional side elevation of a preferred embodiment similar to the fifth embodiment described hereiabove and shown in Figure 5. Figure 10 depicts an especially preferred embodiment of the present invention wherein receptacle 64, similar to receptacle 64 in Figure 5, is provided with a base unit 31, which base unit 31 supports a waste container 68a which container 68a is similar to another container 68b. Base unit 31 is similarly equipped with a bag holder 69 for holding roll 45 in place. Base unit 31, as above, includes projection 71 designed to be acconunodated by aperture 72 formed in bottom surface 74 of container 68a. When projection 71 is accepted by aperture 72, projection 71 engages bottom surface 74 allowing the similar ready detachment of bag 46a (not shown) from bag 46u (not shown). Projection 71 is in a similar fashion, designed to create a sufficient margin between itself and aperture 72 formed in bottom surface 74 to allow passage of bag 46a (not shown) pursuant to the user pulling bag 46 (not shown) in a similar manner, thereby allowing bag 46a (not shown) to enter container 68. Aperture 72 formed in bottom surface 74 is similarly formed with two upraised lips 67, such that any leakage is contained in 5 container 68 and does not soil base unit 31 and/or recession 69. Container 68a is displaceable about a hinge 83 to rest on top of base unit 31, container 68a may also be readily displaced the purposes of cleaning and/or loading of a new roll Base unit 31 is dimensioned to enable nesting of a plurality of containers 68. Specifically, base unit 31 is dimensioned to be accommodated by container 68 10 thereby rendering base unit 31 nestable in container 68 for easier storage and transportation. One of the advantages of containers 68 having a nesting capability is the ability of convenient storage in warehouses while economizing in space until containers 68 are used and/or sold.

The nesting is achieved by raising container 68a above similar container 68b and then accommodating container 68a in container 68b as shown by the arrow designated thus economizing the space taken up by containers 68a and 68b. The procedure described hereinabove is repeated as necessary according to the number of containers 68a and 68b to be nested.

Another nestable configuration is shown in Figures 11 and 12, wherein a container 90 includes a rim 94 similar to rin 29 shown in Figure 1, and described hereinabove in relation to the first embodiment. Container 90 also includes a bottom surface 96 having a nesting ridge 92. Furthermore, a base 100 (Figures 13 and 14) is detached and stored separately thereby enabling storage of spare parts without having recourse to storing containers 90 and bases 100 attached one to each other. Base 100 includes a hollow cavity 102 formed therein as well as a roll holder 106 protruding into cavity 102. Base 100 further includes a gripping surface 5 108 including a cavity 109 formed therein. Cavity 109 is sized to accept the upper end of gripping surface 108 when another base 108 is placed therebeneath. Due to base 100 having cavity 102 formed therein and holder 106 protruding into cavity S 102 as well as gripping surface 108 having cavity 109, bases 100 are nestable in the manner shown in Figure 13.

*0* A further nestable configuration is shown in Figures 15 and 16, wherein a container 110 includes a nesting ridge 112 and a rim 114. Furthermore, a base 117 similar to base 100 (Figures 13 and 14) is attached to, or integrally formed with, container 110. Base 117 is also dimensioned to have a smaller size than container 110 thereby rendering base 117 nestable in container 110 for easier storage and transportation. Typically, when containers 110 are nested, base 117 will rest on rdge 112.

Figures 17 and 18 depict yet a further configuration which is identical in all aspects to the configuration of Figures 15 and 16 but for the absence of nesting ridge 112 shown in Figures 15 and 16. Container 110 similarly includes rim 114 and base 117 is likewise attached to, or integrally formed with, container 110.

Base 117 is also dimensioned to have a smaller size than container 110 thereby rendering base 117 nestable in container 110 for easier storage and transportation.

Typically, when containers 110 are nested, base 117 will rest on base 117 of contam:r 110 immediately therebeneath. Owing to the absence of any ridges, the present configuration offers an alternative and more compact nesting configuration than the configuration shown in Figures 15 and 16 and described hereinabove for the convenience of the user and/or retailer.

Figures 19-25 show the steps of using a waste container 120, as well as loading and replacing a bag 46u according to the present invention. In Figure 19, container 120 with a lid 57 and base 78 is shown prior to being loaded. The process is achieved by performing the following steps: first, displacing container 120 substantially away from base 78. Second, inserting bags 46 into recess 28. Third, passing bag 46 through aperture 72. Fourth, displacing container 120 towards base 78 and then pulling bag 46 substantially towards opening 138 and over rim 94. Alternatively and preferably it would also be possible to pull bag 46 substantially towards opening 138 and over rim 94 and then to displace container 120 towards base 78.

Once container 120 has been used as described hereinabove, the user will verify bag 46 should be replaced and soon thereafter will displace bag 46u substantially towards opening 138. The user will then proceed by disconnecting bag 4 6u from adjacent bag 46a. The task is then completed by disposing bag 46u.

Occasionally the user is advised to verify that plurality of bags 46 have been depleted whereby he will proceed to perform the following steps: first, displacing container 120 substantially away from base 78. Second, inserting bags 46 into recess 28. Third, passing bag 46 through aperture 72. Fourth, pulling bag 46 substantially towards opening 138 and over rim 94 and then displacing container 120 towards base 78.

In order to further clarify the process of using the device according to the present invention with reference to the accompanying drawings a user may remove lid 57 (Figure 20) wherein shortly thereafter container 120 is displaced about hinge 82. Immediately after container 120 is displaced, roll of bags 45 is inserted into roll holder 28. The next step is performed sheet of bags 46 (Figure 21) being placed over gripping surface 71 in the direction generally indicated by Soon thereafter, container 120 is displaced back towards base 78 in the direction 10 generally indicated by The next step is for sheet of bags 46 to be passed through aperture 72 formed in container 120 and pulled substantially upwards in the direction indicated by (Figure 22). Thereafter, bag 46u (Figure 23) is pulled over rim 94 (not shown) and preferably secured to container 120. Lid 57 (Figure 24) is then promptly placed upon container 120 and once bag 46u becomes full or needs to be replaced, lid 57 is duly removed, bag 46f (Figure 25) is displaced substantially upwardly in the direction indicated by until lines 48 are visible where the user tears bag 46f from the new bag 46u to be used and disposes of now full bag 46f. Accordingly, the user pulls bag 46u over rim 94 and places lid 57 back onto container 120 as shown in Figure 24. Once roll 45 is depleted, the user will repeat the process shown in Figures 19-15 and described hereinabove.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrated embodiments and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention is indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
