The disclosure relates generally to plastic liners or bags for use in trash receptacles. More particularly, the disclosure relates to an assembly of plural, nested liners for sequential use with a trash receptacle.
Bags or liners made of plastic have found widespread use in facilitating the collection of refuse and trash. A liner is used to line the interior surface of a trash receptacle thereby serving as a cover for the interior surface of the receptacle to keep the receptacle cleaner and facilitate removal of the trash in it. A liner is a bag with an opening. The opening of the liner is either dimensioned to fit over the mouth of a trash receptacle or is resilient-enough to be stretched over the receptacle'"'"'s mouth. When the receptacle needs to be emptied of trash, the liner with the trash inside it is removed from the receptacle, with the liner serving as a convenient interim holder for the trash. After removal, the liner may be tied or bound with a twist tie near its mouth.
Liners facilitate the gathering of trash and they help to keep the inside of a trash receptacles cleaner, and they also protect those gathering trash to collect trash from trash receptacles. The edges of the liner mouth are simply gathered together and used to lift the liner free of the receptacle, so there is usually no need to touch the trash itself or clean the receptacle. A replacement liner is then inserted into the receptacle.
Despite the use of liners, it takes time and effort to gather trash. For example, an office building may have hundreds of trash receptacles that in which the removal of the old liner and its replacement with a new one is done daily. A more efficient and productive way to collect trash from receptacles would be well-received.
A nested liner assembly is a plurality of trash receptacle liners, one liner inside the other, with tabs on the liners to facilitate removal of an innermost liner from the others, leaving the remainder of the liners, including the next innermost liner, ready for use in the receptacle. A feature of the present disclosure is that, unlike the prior art, wherein a new liner has to be inserted into the trash receptacle after the previous one has been removed with its contents of trash, the present nested liner assembly already has a next liner in place. The nested liner assembly is put onto the trash receptacle and then the innermost liner is removed first, leaving the next liner for use, continuing in the same manner until the liners are filled and removed in sequence. The number of liners can be a large number depending on the thickness of the liner.
Liner thickness may be measured in mils, which are thousandths of an inch or in millimeters. A liner is thicker or thinner with respect to another liner depending on its thickness measured in either mils or millimeters.
The nested liner assembly thus reduces the effort to collect trash whenever it is used.
A collar that holds the nested liner assembly to the receptacle is a feature of the disclosure. The collar facilitates assembling the array, holding the array to the trash receptacle, and separating liners. A series of holes is formed in the collar to enable air trapped inside the nested liner assembly between the liners, the inter-liner air, to be vented so that the assembly itself can be packaged more compactly for shipment and storage.
Another feature of the nested liner assembly is the use of a more durable plastic liner, a strong liner in other words, as the outermost liner and which will hold up through the use of a plurality of liners.
Another feature of the nested liner assembly is the use of tabs on the liners to facilitate removal. The tabs are a visible and easily-grasped pair of handles for the user to grip in order to separate the top of the innermost liner from the rest of the nested liners.
Those skilled in the art of trash collection materials and methods will appreciate these and other features and their advantages from a careful review of the Detailed Description accompanied by the following drawings.
Referring now to the drawings,
The disclosure describes a nested liner assembly and method for making it. The nested liner assembly is for use with trash receptacles and is sized for the particular receptacle it is used with.
The set of liners is a nested set of thin plastic liners. The set contains a plurality of liners. The term nested means that one liner is inside the next so that there is an innermost liner and an outermost liner with the remainder of the liners arranged between them, one inside another, running from the innermost liner to the outermost liner.
After installation of the assembly on a trash receptacle, the innermost liner is used to receive trash first. The innermost liner is the liner that is removed first. That liner is removed by pulling on its spaced-apart tabs, which enable the user to separate it from the balance of the liner assembly. After that liner is removed, the next liner immediately presents itself as the new innermost liner, ready for use. As a liner is filled with trash, it is removed, continuing to the removal of the outermost liner is removed. The outermost liner is inside a strong liner that is removed with the outermost liner from the trash receptacle to allow a nested liner assembly to be installed as a replacement on the trash receptacle.

When the last of liners 26 have been filled with trash and removed from nested liner assembly 10, belt 18 is loosened where it overlaps itself (as seen in
Collar 30, as seen in an exploded, pre-assembled view in
Outer band 58, which has a longer long dimension when compared to the long dimension of inner band 66, is shortened so that its shortened long dimension is the same length as that of central band 62 and inner band 66, Shortening outer band 58 is accomplished by the formation of a series of pleats 70 in outer band 58. Pleats 70 also enable outer band 58 to be bent over the rim 32 easily. After outer band 58 is pleated, it is joined to central band 62 and to inner band 66. Outer band 58, central band 62, which is joined to inner band 66. Outer, central and inner bands 58, 62, and 66 may be joined in any convenient way, such as tape, adhesives, sewing, or heat welding, for example.
After collar 30 is assembled from the combination of outer band 58, central band 62, and inner band 66, it is attached to the mouth 78 of strong liner 46 so that edge 38 overlaps mouth 78 of strong liner 46. Mouth 78 of strong liner 46 may overlap inner band 66 and does not cover holes 54 and does not overlap outer band 58. Collar 30 is attached to strong liner 46 using tape 82. Alternatively, an adhesive or heat seal may be used to attach strong liner 46 to collar 30.
At this point in construction, strong liner is inverted, as shown is
To nest a series of liners 26, a first mandrel 90 with a base 94 is provided. First mandrel 90 has a bottom 96 having the same size as mouth 42 of liner 26, a smaller top 98, and a side 102 made of mesh. First mandrel 90 is connected to a vacuum pump 106 to draw air through side 102 from outside first mandrel 90, as shown in
A nested series of liners 26 are tucked into trough 86, and outer band 58 is then folded against the balance of collar 30 and attached, for example, held to liners 26 as a unit by using tape 126 as shown or by using adhesives.
The number of liners 26 may be any convenient number selected with a view to the type of trash, liner thickness, and frequency of trash collection. For example, there may be at least 20 liners nested in one nested liner assembly 10. Twenty-five liners may be a one-month supply for use in an office building trash receptacle. A larger number, such as 50 or 75, may be advantageous because it reduces the number of times in a year a nested liner assembly 10 may be used per receptacle.
The almost-completed nested liner assembly 10 is then rolled or pressed to expel any remaining air from the inter-liner spaces through holes 54. A strip of tape 130 is then applied over holes 54 to prevent air from re-infiltrating nested liner assembly. Nested liner assembly 10 is then ready to be installed on a trash receptacle 14.
To install nested liner assembly 10 onto a trash receptacle14 as seen in
Belt 18 is folded so that release paper 138 is just after the half way part of the fold. Belt 18 may be a continuous loop with a patch 134 of adhesive along one side and a release paper 138 on top of the patch. The release paper 138 may then be removed and the patch 134 pressed against the belt 18 to hold a bite 142, that is, a fold or loop, in belt 18, to reduce the effective circumference of belt 18 to match the circumference of trash receptacle 14. Belt 18 will be sized to be somewhat larger than the trash receptacle for which it is intended.
Those skilled in the art of trash liner collection will appreciate various modification and substitutions may be made to the foregoing description of aspects of the disclosure that fall within the spirit and scope of the claims that follow.
