Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a non-provisional application of Applicant&#39;s Provisional Application Ser. No. 60/906,138 filed on 9 Mar. 2007. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a draw tape bag with an adhesive strip on at least a portion of the periphery of the draw tape hem, the draw tape bag conventionally used as a waste can liner. 
     2. Prior Art Statement 
     It is known to provide a trash can liner an adhesive patch disposed on the exterior surface of the draw tapes in the area of a cutout in the hem. After inserting the liner into the can and folding the closure end of the bag over the rim of the can, an end of the tape is drawn tight and secured to the adhesive patch to retain the liner in the can. The adhesive patch is initially covered with a strippable cover. For instance, see the U.S. Pat. No. 7,137,737 B2 issued on Nov. 21, 2006 to Jakob Schneider. The adhesive portion is provided only on an end of the draw tape for securing the draw tape tightly around the exterior of the can below the rim. Also, the liner is a conventional type liner that is folded over the rim of the can which covers the rim of the can thus detracting from the aesthetics of a decorative waste can. Furthermore, the liner is of conventional opaque material further hiding any decorative features of the can. Additionally, since the liner extends over the rim, material is wasted in manufacture and that added material contributes to landfill waste. Thus there is a need for a waste can liner that comprises a first wall, a second wall, a closed bottom and an open top, where the open top contains a draw tape within a hem and where the hem further has an adhesive strip applied to an exterior surface thereof for adhering the liner to an inside surface of a waste container. 
     It is also known to provide a trash can liner that has an adhesive strip at the top edge for adhering the liner to the inside of the trash can and/or to other surfaces inside the receptacle. For instance, see the U.S. Patent Publication 2005/0129335A1 published on Jun. 16, 2005 by Samuel Louis Paul. Only a small area is provided with means to adhere the bag to the can which leads to gaps between the edges of the can and the liner. Additionally, no draw tape is provided thus making the liner difficult to remove from the can. Another liner has an adhesive strip on the exterior of a waste bag for adhering a portion of the waste bag to a stationary object such as a wall or tree. A tab is provided on the end of the adhesive strip for facilitating closure of the bag when full. For instance, see the U.S. Pat. No. 5,913,606 issued on Jun. 22, 1999 to Jerome Nicholson. The adhesive on the bag of Nicholson is disposed well below the top edge of the bag and thus also results in wasted material and additional landfill material. A similar liner is described in Campbell, et al., U.S. Pat. No. 4,904,092 issued on Feb. 27, 1990 which provides an adhesive strip across the top of the bag to facilitate opening the bag when withdrawing a bag from a stack or roll. The adhesive is said to be useful in retaining the bag closed by twisting the bag at the location of the adhesive. The liner of Campbell, et al., cannot be fitted with a draw tape in a hem and maintain the liners in a roll and the liners of Paul and Nicholson do include a draw tape disposed within a hem with the adhesive on the exterior of the hem. Therefore, there is a need for a waste can liner that comprises a first wall, a second wall, a closed bottom and an open top with a draw tape within a hem in the top thereof wherein the hem further has an adhesive strip applied to an exterior surface thereof, the hem provided with a cutout in a portion thereof for access to the draw tape, the adhesive strip comprising a high tack surface and a low tack surface where the high tack surface applied to the external surface of the hem and the low tack surface is covered with the removable protective strip. 
     It is further known to provide a trash bag that has an adhesive strip at the top of the bag on both the inside and outside of the bag. The outside adhesive layer is used to secure the bag to the inside of the waste container and the inside adhesive is used to close the bag. The adhesive layers have peelable protective strips covering the adhesive. For instance, see U.S. Pat. No. 6,837,394 B2 issued on Jan. 4, 2005 to Patricia Ann Nnamani. There is no means to reduce the size of the bag for different sized cans, no draw tape is provided nor is there a fold in the bottom of the bag. Accordingly, there is still a great need for a liner for a waste receptacle that comprises a first wall, a second wall, at least one draw tape hem, at least one draw tape and at least one adhesive strip where the first wall and the second wall are joined together along terminal side edges thereof and wherein the adhesive strip is applied to an exterior surface of the draw tape hem, a fold is provided in the bottom of the bag and an additional adhesive strip is provided reduce the size of the bag. 
     Finally, it is known to provide nested bag liners that have an adhesive provided on tabs extending from the upper edge of the bag to keep the bags together in a nest. The bags also of conventional structure and are intended to be rolled over the edge of the waste can. The adhesive on the tabs may additionally be used to close the bag in a half knot adhering the tabs to the outside of the bag. For instance, see the U.S. Pat. No. 6,808,073 B2 issued on Oct. 26, 2004 to Jarret P. Cuisinier. The function of the adhesive is to keep the liners together in a nest over the edge of the can. Yet another liner is shown in Ling, et al., U.S. Pat. No. 4,978,231 issued on Dec. 18, 1990 wherein an adhesive strip is located on an outside surface of the bag for adhering the bag to the outside of the receptacle. The liners are also heat melted together into a nest. Additional material is needed to extend either liner over the edge of the can as in Ling, et al., and to provide for the tab of Cuisinier at the extreme end of the liner. This results in greater production costs and contributes to additional landfill waste. Furthermore, the liner is not adhered to the inside of the receptacle. Hence, there is still a need for liner for a waste receptacle that has at least one draw tape hem disposed on an open end of the liner, at least one draw tape disposed in the hem and at least one adhesive strip applied to the exterior surface of the draw tape hem, the hem further provided with a cutout in a portion thereof for access to the draw tape peel the liner from the container.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     While the various features of this invention are hereinafter described and illustrated as a waste can liner provided with a draw strip enclosed in a hem at a top end thereof and a gusset fold in a bottom end thereof wherein the hem is further provided with at least two adhesive strips on an outside surface for adhering the liner to an inside surface of a rigid container thus keeping the liner in an open posture within the container, it is to be understood that the various features of this invention can be used singly or in various combinations thereof to provide for a waste can liner with an adhesive attachment, a light transmissible skin, a draw tape and size reduction means as can hereinafter be appreciated from a reading of the following description. 
     Referring now to  FIG. 1 , a liner for a waste receptacle, generally shown by the  FIG. 10 , comprises a first wall  18 , a second wall  20 , at least one draw tape hem  30 ,  32 , at least one draw tape  38 ,  48  and at least one adhesive strip  15 ,  15 .′ Second wall  20  is an extension of first wall  18 , first wall  18  and second wall  20  created by slitting lengthwise an elongated tube  101  as shown in  FIG. 2 . Second wall  20  is laid adjacent first wall  18  by flattening tube  101  by suitable means such as a flattening mechanism  102 . As best observed in  FIG. 3 , draw tape hem  30  comprises an extension of at least a portion  21  of a free end  24  of first wall  18  and draw tape hem  32  comprises at least a portion  23  of a free end  26  of second wall  20 . A portion of draw tape  38  is laid adjacent a terminal end  25  of free end  24  of first wall  18  and a portion of draw tape  48  is laid adjacent a terminal end  27  of free end  26  of second wall  20  wherein terminal end  25  of free end  24  of first wall  18  is folded over draw tape  38  and preferably joined to an interior surface  28  of first wall  18  and terminal end  27  of free end  26  of second wall  20  is folded over draw tape  48  and joined to an interior surface  29  of second wall  20 . First wall  18  and second wall  20  are ultimately joined together at sealing/severing joint  17  of  FIG. 2  thus creating terminal side edges  11 ,  12  thereof after an adhesive strip  15  is applied to an exterior surface  31  of draw tape hem  30  and preferably, an adhesive strip  15 ′ is applied to an exterior surface  33  of draw tape hem  32 , adhesive strips  15 ,  15 ′ covered by a removable cover  16 ,  16 ′ respectively, prior to joining terminal side edges  11 ,  12 . 
     Referring again to  FIG. 1  and also to  FIG. 3 , adhesive strip  15  preferably is about one quarter inch in width and extends the entire length of hem  30  between terminal side edges  11 ,  12  and likewise, adhesive strip  15 ′ extends the entire length of hem  32  between terminal side edges  11 ,  12 . As covers  16 ,  16 ′ are applied prior to joining walls  18 ,  20  together at sealing/severing joints  17 , covers  16 ,  16 ′ are severed at sealing/severing joints  17  by the thermal action of edge sealer/cutter  109 . Covers  16 ,  16 ′ are preferably printed with “TO EXPOSE ADHESIVE, REMOVE COVER,” this legend  42  represented in  FIGS. 1 and 4  by Greeking  19 . Hems  30 ,  32  are provided with cutouts  36  in a portion thereof for access to draw tapes  38 ,  48  respectively. Preferably, cutouts  36  are about one and one half inches in width as measured along hem  30 ,  32  and are about one half inch in depth extending into reformed top edge  50 . Cutouts  36  are typically shaped as an arch and are centrally disposed in hems  30 ,  32  to assist in peeling liner  10  from a container, not shown, as a centrally disposed pull on draw tapes  38 ,  48  provides for equal separation of adhesive  15 ,  15 ′ from opposite sides of the container and from portions of the container adjacent each cutout  36 . Additionally, as is well established in the art, liner  10  also allows for equal gathering of hems  30 ,  32  about draw tapes  38 ,  48  while closing liner  10  about the contents captured therein. 
     In the preferred embodiment of liner  10 , first wall  18  and second wall  20  are provided with an inwardly directed fold  14  disposed therebetween opposite free ends  24 ,  26  thereof. Inwardly directed fold  14  is formed into bottom  13  by forcing walls  18  and  20  to double inwardly whereafter the newly formed folded bottom  39  is pressed to ensure that inwardly directed fold  14  is retained in liner  10  prior to sealing terminal side edges  11 ,  12 . Accordingly, when terminal side edges  11 ,  12  are joined at sealing/severing joints  17 , ends  35 ,  37  of inwardly directed fold  14  are simultaneously joined to terminal side edges  11 ,  12 . Inwardly directed fold  14  allows for expansion of liner  10  into various shaped waste receptacles without producing a specific liner  10  for each specific waste receptacle. The depth of inwardly directed fold  14  from into folded bottom  39  may be up to about one-third of a width  51  between terminal side edges  11 ,  12  but is preferably about two inches (2″) for liner  10  in a generally rectangular form of fourteen inches (14″) in width  51  and eleven and one quarter inches (11¼″) in length from reformed top edge  50  to new base  49  of folded bottom  39 . Preferably, folded bottom  39  is a “C” fold having equal lengths of walls  18 ,  20  folded inwardly into bottom  13 . As several different sized liners  10  are contemplated, it follows that folded bottom  39  is proportional to width  51  of liner  10  between terminal side edges  11 ,  12  in order for liner  10  to essentially stand up in a waste can when folded bottom  39  is opened. 
     It is preferred that liner  10  be constructed of a transparent or translucent material selected from the group comprising polyethylene, low density polyethylene, ultra low density polyethylene, polypropylene, ethylene vinyl acetate, ethylene-methyl acrylate, ethylene-ethyl acrylate, and mixtures thereof and preferably are oriented films having a greater resistive strength in one direction. Though an oriented film is preferred, it is within the scope of this invention to produce liner  10  of sheet material having equal strength in both the length of liner  10  from free ends  24 ,  26  to bottom  13  and width  51  of liner  10  between terminal side edges  11 ,  12 . Removable cover  16 ,  16 ′ is preferably constructed of a thermoplastic film selected from the group comprising polyethylene, polypropylene, isophthalic polyester, terephthalic polyester, orthophthalic polyester, acetals, vinyls, tetrafluoroethylenes, propylenes, styrenes, amides, amide-imides, parabenzamides, vinylchlorides, carbonates, ABS, acrylates, or combinations thereof. Most preferably, removable cover  16 ,  16 ′ has one surface that will temporarily cling to adhesive  15 ,  15 ′ yet readily release therefrom when peeled at an angle from adhesive  15 ,  15 ′. Removable cover  16 ,  16 ′ is provided with the aforementioned legend  42  to guide the user of liner  10  toward the proper usage thereof. Draw tapes  38 ,  48  are typically formed from thermoplastic material selected from the group comprising polyethylene, low density polyethylene, ultra low density polyethylene, polypropylene, ethylene vinyl acetate, ethylene-methyl acrylate, ethylene-ethyl acrylate, and mixtures thereof and preferably are oriented films having a greater resistive strength in a length of draw tape  38 ,  48 . Draw tapes  38 ,  48  of thermoplastic material are preferably about one inch in width, however, it is within the scope of this invention to provide for wider or narrower draw tapes  38 ,  48  as well as produce draw tapes  38 ,  48  of other materials such as natural or synthetic fibers or combinations thereof. 
     As liner  10  is constructed of a transparent or translucent material, liner  10  may alternately be provided with at least one decorative applique  40  on at least one of an interior surface  28 ,  29  of first wall  18  and/or second wall  20 . Additionally, or alternately liner  10  may be provided with at least one decorative applique  40  on at least one of an exterior surface  31 ,  33  of first wall  18  and/or second wall  20 . Decorative applique  40  may be of any art work, whether real or abstract, depicting still life, wildlife, heavenly bodies, shapes, patterns or objects and thus is shown in  FIG. 4  only as parallel wavy lines  41 . Selected designs for decorative applique  40  are shown in  FIG. 5   a - c  though other designs are within the scope of this invention. Additionally, it is within the scope of this invention to produce material for liner  10  that is colored though still translucent or transparent. 
     Adhesive strip  15 ,  15 ′ comprises a high tack surface  43  and a low tack surface  44 , high tack surface  43  applied to exterior surface  31 ,  33  of hem  30 ,  32  and low tack surface  44  covered with removable protective cover  16 ,  16 ′. High tack surface  43  ensures that adhesive  15 ,  15 ′ is retained on liner  10  and no residual is left on the waste container when liner  10  is removed therefrom. Adhesive strip  15 ,  15 ′ is preferably continuous across hem  30 ,  32  but it is within the scope of this invention to provide for closely and regularly spaced applications of adhesive thus effectively producing a continuous strip. Though adhesive strip  15 ,  15 ′ is typically one quarter inch (¼″) in width and protective cover is one half inch (½″) in width, it is fully within the scope of this invention to provide a narrower or wider strip. An adhesive for adhesive strip  15 ,  15 ′ may be selected from the group comprising acrylic, styrene, isoprene, synthetic polyisoprene, butadiene-styrene (SBR) polymers, thermoplastic rubbers, blocked polymers thereof or combinations thereof and preferably is finger lift tape #7040 available from Bisco International, Inc., 543 Granville Ave., Hillside, Ill. 60162. Finger lift tape #7040 is a one quarter inch rubber based adhesive deposited on an one half inch wide polyethylene carrier and covered with a one half inch wide polyethylene protective cover  16 ,  16 ′. An alternative high tack/low tack tape, F9415PC-high-tack/low tack removable adhesive double coated film is available from Minnesota Mining Company, Building 21-1W-10, 900 Bush Avenue, St. Paul, Minn. 55144-1000. 
     In addition to adhesive strip  15 ,  15 ′ placed on hems  30 ,  32  at least a portion of external surface of first wall  18  and/or second wall  20  may have an additional adhesive strip  45  affixed thereto at installation of liner  10  into a waste receptacle wherein adhesive strip  45  is used to reduce the periphery of liner  10 . Adhesive strip  45  is preferably disposed transverse to adhesive strip  15 ,  15 ′ affixed to hems  30 ,  32  when installing liner  10 . Initially, additional adhesive strip  45  is covered with removable protective strips  46 ,  47  as additional adhesive strip  45  is packaged with, but separate from liner  10 . Adhesive strip  45  is shown separated from liner  10  in  FIG. 4  with dashed lines toward and onto liner  10  to show application of additional adhesive strip  45  to liner  10 . When applying additional adhesive strip  45  to liner  10 , protective cover  47  is removed exposing adhesive  45  whereupon additional adhesive strip  45  is applied to liner  10 . Protective cover  46  is then removed exposing adhesive  45  and a portion of exterior surface  31  is folded over the exposed adhesive previously covered by protective cover  46  and hence, exterior surface  31  then assumes a new width  51 . In the process of folding a portion of exterior surface  31 , hem  30  is likewise folded and adhesive  15  at hem  30  is folded upon itself whereupon hem  30  is similarly reduced in length and held in place by a portion of adhesive  15  against another portion of adhesive  15  and thus liner  10  assumes a new periphery. Of course, more than one additional adhesive strip  45  may be applied to liner  10 , however, it has been found by the inventor hereof that only one additional adhesive strip  45  is usually needed to sufficiently reduce the periphery of liner  10  for the purpose of placing liner  10  into a waste receptacle of a size smaller than the full periphery of liner  10 . Though additional adhesive strip  45  has been hereinbefore described and shown in  FIG. 4  as a separate rectangular strip approximately three quarters of an inch (¾″) square, it is fully within the scope of this invention to provide a different shape, such as round or oval, for additional adhesive strip  45  and it is also within the scope of this invention to apply a surface thereof generally covered by protective cover  47  to each liner  10  leaving protective cover  46  in place. 
     Liner  10  is preferably rectangular in general shape, however, it is within the scope of this invention to provide for tapered terminal side edges  11 ,  12  by providing a “V” shaped edge sealing/cutting blade in edge sealer/cutter  109 . Accordingly, liner  10  of a height of twelve inches (12″) may assume a width  51  at hem  30 ,  32  of fourteen inches (14″) and a width  51  at new base  49  of eleven (11) inches. It is within the scope of this invention to provide for different tapers to side edges  11 ,  12  as dictated by different tapered waste receptacles. Liner  10  has been designed to fit in round, square, rectangular or oval trash containers which may be made of ceramic, plastic, metal, wood or other materials. Primarily, liner  10  is best used in small trash containers typically measuring about thirteen inches (13″) in height, though it is within the scope of this invention to provide liner  10  which can be used in larger containers and therefore this application is not intended to be restricted by the height parameter. Typical round waste receptacles for home bathrooms, bedrooms and/or offices have a circumference of about 28 inches and the perimeter of rectangular waste receptacles is about 30 inches while the perimeter for an oval waste receptacle is about 25 inches. Accordingly, liner  10  is manufactured to a width of fifteen inches (15″) to provide a perimeter of 30 inches when opened and additional adhesive strip  45  is used to reduce the perimeter thereof when using liner  10  for oval or rectangular waste receptacles. For instance, oval or rectangular waste containers generally used in bathrooms and bedrooms are about twelve inches (12″) as measured in the major direction and about eight inches (8″) in the minor direction with a height of thirteen inches (13″) or less. Round waste receptacles also generally used in bathrooms and/or bedrooms may be about ten inches (10″) in diameter while square waste containers are about ten inches (10″) square but still about thirteen inches (13″) in height. Larger kitchen waste containers are usually greater than thirteen inches (13″) in diameter and at least 18 inches in height. 
     In use, liner  10  is first opened and folded bottom  39  expanded outwardly and then inserted into a waste container whereupon liner  10  basically sits on an interior bottom surface of the container. Protective cover  16  covering pressure adhesive strip  15  on one hem  30  is removed by gripping a free end  52  thereof and completely removing protective cover  16  thereby exposing adhesive strip  15 . Adhesive strip  15  is then pressed against an inside rim of the container and smoothed against the inside rim along the length thereof. Protective cover  16 ′ on opposite hem  32  is then removed in a like manner and exposed pressure adhesive strip  15 ′ is smoothed against a remainder of the inside rim of the waste container. If liner  10  is greater in circumference than the waste receptacle, additional adhesive strip  45  is placed on interior surface  28 ,  29  of liner  10  and a portion of interior surface  28 ,  29  folded over additional adhesive strip  45  thus reducing liner  10  in circumference. Thereafter, hem  30  or  32  contiguous with the interior surface receiving additional adhesive strip  45  is folded against itself whereupon adhesive  15 ,  15 ′ adheres to itself in the area of the fold. It should be apparent here, that once adhesive strip  15 ,  15 ′ is smoothed against the inside rim of the container and, if necessary, liner  10  reduced in circumference, as folded bottom  39  has been opened and rests against the inside surface of the waste receptacle, liner  10  effectively fills the volume of the waste container. When the interior volume of liner  10  has received sufficient waste to approach its total capacity, a portion of draw tapes  38 ,  48  exposed in cutouts  36  is taken hold of and gently pulled, thus separating liner  10  away from the waste container thus allowing for clean and sanitary removal of liner  10  containing waste. Liner  10  of  FIG. 4  may similarly be inserted and removed from a waste container though liner  10  of  FIG. 4  will not typically stand erect on an inside surface of the bottom of a waste receptacle. 
     In one method of manufacturing waste can liner  10 , a thermoplastic extruder  110  produces a thin wall tube of extrudate which is expanded greatly in diameter by introducing air into, and capturing the air within, the heated extrudate to produce a blown thermoplastic tube  101 . Expanded thermoplastic tube  101  may then flattened into a double walled structure, ultimately becoming walls  18 ,  20  of liner  10 , by passing expanded thermoplastic tube  101  through a flattening mechanism  102  such as a roller disposed at an angle to the direction of travel of expanded thermoplastic tube  101  from extruder  110 . The double walled structure is slit along the length thereof by a tube slitter  104  thus creating walls  18 ,  20  having free ends  24 ,  26  respectively, walls  18 ,  20  joined together along a bottom  13 . A bottom folder  103  produces a gusset, or “C” shaped, inwardly directed fold in bottom  13  of the double walled structure, bottom folder  103  reforming bottom  13  into a folded bottom  39 . Separate free ends  24 ,  26  are folded inwardly and separately pressed by a hem folder  105  thus creating hems  30 ,  32  as fully described in the U.S. Pat. No. 6,602,174 B1 issued on 5 Aug. 2003 to Haverfield, et al., the entire specification thereof incorporated into this application by this reference thereto. As also described in the aforementioned reference to Haverfield, et al., at least one hem  30 ,  32  has a cutout  36  provided therethrough by a cutout punch  106 , cutout  36  provided for access to a draw tape  38 ,  48  when removing liner  10  from a waste receptacle and closing liner  10 , draw tapes  38 ,  48  inserted into hems  30 ,  32  respectively. Draw tapes  38 ,  48  are inserted into previously folded hems  30 ,  32  by introducing draw tapes  38 ,  48  at an angle to the machine direction (MD) of manufacturing of liners  10 , draw tapes  38 ,  48  passing over separate rollers  111 ,  112  disposed in opened hem  30 ,  32  respectively. Rollers  111 ,  112  insert draw tapes  38 ,  48  adjacent an inside bight of portions  21 ,  23  respectively, draw tapes  38 ,  48  maintained in position by tension on draw tapes  38 ,  48 . Terminal ends  25 ,  27  of walls  18 ,  20  respectively are sealed to interior surfaces  28 ,  29  of walls  18 ,  20 , respectively, at a seam  34  by a hem sealer  107 , hem sealer  107  preferably a thermoplastic sealing mechanism well known in the art for sealing thermoplastic materials. Upon closure of hems  30 ,  32 , hems  30 ,  32  are further provided with adhesive strips  15 ,  15 ′ on exterior surfaces  31 ,  33  thereof, adhesive strips  15 ,  15 ′ of hems  30 ,  32  adapted for adhering liner  10  to an inside surface of a rigid waste container thus keeping liner  10  in an open posture within the waste container. As hereinbefore described, adhesive  15 ,  15 ′ may be applied by an adhesive applicator  108  as a continuous strip approximately one-quarter inch in width, however, a continuous strip of adhesive  15 ,  15 ′ is not limiting within the scope of this invention. Adhesive strips  15 ,  15 ′ preferably have high tack surfaces  43  applied to exterior surfaces  31 ,  33  between seam  34  and a lower cusp  22  of cutout  36  with low tack surfaces  44  initially exposed. Adhesive strips  15 ,  15 ′ may then be covered with removable covers  16 ,  16 ′ by introducing removable covers  16 ,  16 ′ at an angle to machine direction MD, removable covers  16 ,  16 ′ rolled onto, and temporarily adhered to, adhesive strips  15 ,  15 ′ by separate rollers  113 ,  114 . Removable covers  16 ,  16 ′ are shown as being introduced at a right angle to machine direction MD from one side, however it is fully within the scope of this invention to introduce removable covers  16 ,  16 ′ from above and below apparatus  100 . Upon rolling removable covers  16 ,  16 ′ onto adhesive strips  15 ,  15 ′, liners  10  are created by sealing side edges  11 ,  12  at sealing/severing joints  17 . Preferably, however, adhesive strips  15 ,  15 ′ are applied as a tape already disposed on a carrier (not shown) with covers  16 ,  16 ′ removably applied to an opposite side of adhesive strips  15 ,  15 ′. This tape structure is applied to exterior surfaces  31 ,  33  by rollers  113 ,  114  by introducing the tape structure, including adhesive strips  15 ,  15 ′ and covers  16 ,  16 ′, at an angle to machine direction MD while removing the carrier. Side edges  11 ,  12  of adjacent liners  10  may remain joined at sealing/severing joints  17  whereupon liners  10  are disposed upon a roll  115  of apparatus  100  or may be separated at sealing/severing joints  17  and nested in a stack  116  for ultimate placement in a box or bag for consumer use. 
     Though the preferred method of making liner  10  has been described, it is fully within the scope of this invention to produce liner  10  by folding a sheet of suitable thermoplastic material first in half, folding each wall  18 ,  20  again backwardly from a first bottom fold  13 ′ to establish inwardly directed “C” fold  14 , folding a free end  24  of wall  18  inwardly to produce hem  30 , folding free end  26  of wall  20  inwardly producing hem  32 , cutting cutouts  36  in hems  30 ,  32  by suitable means, introducing draw tape  38  into hem  30  and draw tape  48  into hem  32 , sealing hems  30 ,  32  at seam  34  by suitable means thus creating newly formed top edge  50 , laying adhesive strips  15 ,  15 ′ across width  51  of walls  18 ,  20  adjacent seam  34  on portions  21 ,  23  of free ends  24 ,  26  respectively, covering adhesive strips  15 ,  15 ′ with protective covers  16 ,  16 ′ and sealing side edges  11 ,  12  from newly formed top edge  50  to new bottom  49  whilst sealing side edges  35 ,  37  of inwardly directed “C” fold at side edges  11 ,  12 . In either method of forming liner  10 , waste can liner  10  is provided with draw strip  38 ,  48  enclosed in hem  30 ,  32  respectively at top end  50  thereof and a gusset fold  14  is provided in a bottom end  49  thereof. Hem  30 ,  32  is further provided with at least one cutout  36  therethrough for retrieving a portion of draw tape  38 ,  48  when closing liner  10 , hem  30 ,  32  further provided with at least two adhesive strips  15 ,  15 ′ on outside surface of hem  30 ,  32  for adhering liner  10  to an inside surface of a rigid container thus keeping liner  10  in an open posture within the container.
