Abstract

A bag may include opposing first and second sidewalls of a pliable thermoplastic material that may be joined to each other along first and second side seals and a closed bottom. The sidewalls may remain un-joined along their top edges to form an opening into which trash and other items may be deposited. When the bag is placed in a trash receptacle, the un-joined top edges may be folded over the rim of the receptacle to secure the liner to the receptacle. To assist with securing the bag to the receptacle, the side seals may be directed to converge partially toward each other thereby forming a throat in the interior volume proximate the opening. When the top edges are folded over the receptacle rim, the throat may grip the receptacle. The bag may include a pattern between the converging portions. The bag may include a retention strip between the converging portions.

The specific embodiment

With reference to figure 1, show pliable and tough themoplasticity sack 100, sack 100 can be used as the lining that is used for waste canister and sewage disposer.Sack 100 can be made by the first side wall 102 and the second relative sidewall 104, and second sidewall 104 can be stacked with the first side wall and can be connected with the first side wall so that be defined for the internal capacity 106 of maintenance refuse.First and second sidewalls can connect together with closing bottom 114 along first side seals 110, second side seals 112; Said first side seals 110 is corresponding to first edge of sidewall; Said second side seals 112 can be parallel and spaced apart with the first side edge, and said closing bottom 114 extends between first and second side seals.Sidewall 102,104 can be through connecting such as the edge of thermosealed any suitable connection technology along them, and thermoplastic material combines or is fused to together in heat seal.Perhaps connecting technology can comprise ultrasonic method and adhesives in other sealing.

First and second sidewalls 102,104 can be level and smooth by forming or pulling into, the flexible or pliable and tough thermoplastic material of thin-wall net or sheet makes.The instance of suitable thermoplastic material can comprise poly-vinyl (such as high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene, VLDPE), polypropylene, ethylene-vinyl acetate copolymer, nylon, polyester, ethylene-vinyl alcohol copolymer or ethylene-methyl acrylate copolymer, and can form with the mode that combines and form with the form of single or multiple lift.When being used as the sewage disposer lining, thermoplastic material can be opaque usually, but also can be transparent, semi-translucent or colored.In addition, the material that is used for sidewall can be sir-tight material and can comprise other characteristics, such as handling with deodorizer, perfume and/or disinfectant, when producing the pail for used dressings lining, expecting in the time of as some.

In order to get into internal capacity 106, keep not being connected so that opening 124 to be provided with the top 120,122 of first and second sidewalls of bottom 114 relative positionings.With reference to figure 2, the width 126 of opening 124 extends between first side seals 110 and second side seals 112 when first and second sidewalls, 102,104 quilts of sack are set level.Width 126 can have the scope of from about 10 inches (25.4cm) to about 60 inches (152.4cm).When being placed on sack 100 in the waste canister, on said edge, turn back usually corresponding to the top 120,122 of opening 124, in container, remain in the position of vertical extension to help sack.Sack 100 can have height 128.This highly can have the scope of from about 10 inches (25.4cm) to about 60 inches (152cm).

In order to help that sack 100 is remained on the bucket, sack can be formed with some the maintenance characteristic around the peripheral clamping of bucket.In the example embodiment shown in Fig. 1 and 2, keep characteristic can form the part of first and second side seals 110,112.First and second side seals 110,112 (can be straight basically) comprise that first and second contractors, 130,132, the first and second contractors 130,132 are separately partly restrained or extension toward each other sealing the margin.Contractor 130,132 can be the extendible portion of straight side seals 110,112, and the material of wherein relative sidewall physically connects together.In example embodiment, comprise that the side seals 110,112 of relative contractor 130,132 can be a substantial symmetry.

Contractor can be formed on crooked toward each other, the part away from each other afterwards of side seals, and can be positioned to the top 120,122 of opening wide of contiguous sack 100 basically and rightly under it.For example, contractor 130,132 can be positioned at a distance 137 places under the top 120,122 of opening wide as shown in Figure 2.Distance 137 can have first scope of from about 0.5 inch (1.27cm) to about 12 inches (30.48cm); The 3rd scope of second scope of from about 1 inch (2.54cm) to about 6 inches (15.24cm) and from about 2.5 inches (6.35cm) to about 5 inches (12.7cm).In one embodiment, distance 137 can be about 2.75 inches (7cm).Contractor 130,132 can extend and leave side seals 110,112 1 distances 139 toward each other.Distance 139 can have first scope of from about 0.25 inch (0.64cm) to about 6 inches (15.24cm); The 3rd scope of second scope of from about 0.5 inch (1.27cm) to about 4 inches (10.16cm) and from about 1 inch (2.54cm) to about 3 inches (7.62cm).In one embodiment, distance 139 can be about 2 inches (5.08cm).Distance 139 can be a percentum of width 126.This percentum can have from about 1% to about 25% first scope, from about 2% to about 16% second scope and from about 4% to about 12% the 3rd scope.In one embodiment, this percentum can be about 8%.Contractor can have the distance of measuring about side seals 110,112 138.Distance 138 can have first scope of from about 0.5 inch (1.27cm) to about 10 inches (25.4cm); The 3rd scope of second scope of from about 1 inch (2.54cm) to about 6 inches (15.24cm) and from about 2 inches (5.08cm) to about 4 inches (10.16cm).In one embodiment, distance 138 can be about 3 inches (7.62cm).Distance 138 can be a percentum of sack height 128.This percentum can have from about 1% to about 30% first scope, from about 2% to about 20% second scope and from about 4% to about 15% the 3rd scope.In one embodiment, this percentum can be about 7%.In example embodiment, contractor is arc or crooked shape basically, but contractor can have other shapes in other embodiments.That other shape instance that are used for contractor comprise is square, the combination of rectangle, triangle, chevron or these shapes.Figure 21-26 illustrates other shapes that are used for contractor and has described these shapes in this article.

Constitute first and second sidewalls 102 of contractor, the width of actual sealing between 104 can be identical with the width of the sealing that constitutes side seals 110,112.For example, side seals 110,112 can have width 116.Width 116 can have first scope of from about 0.031 inch (0.08cm) to about 0.5 inch (1.27cm); The 3rd scope of second scope of from about 0.063 inch (0.16cm) to about 0.375 inch (0.95cm) and from about 0.094 inch (0.238cm) to about 0.25 inch (0.64cm).In one embodiment, width 116 can be about 0.16 inch (0.41cm).Sealing can have width 134 corresponding to the part of contractor.Width 134 can have first scope of from about 0.031 inch (0.08cm) to about 0.5 inch (1.27cm); The 3rd scope of second scope of from about 0.063 inch (0.16cm) to about 0.375 inch (0.95cm) and from about 0.094 inch (0.238cm) to about 0.25 inch (0.64cm).In one embodiment, width 134 can be about 0.16 inch (0.41cm).In addition, sack 100 can comprise first and second recesses 136 that are arranged in the sack with corresponding to the position of first and second contractors 130,132 in certain embodiments.Recess 136 is inwardly outstanding from side seals 110,112, and can be limited perhaps the sealing that forms contractor 130,132 and depict profile, and can have the arc or crooked shape that is similar to perhaps corresponding to the shape of contractor.Because recess 136 can be not and the sealing interference that forms side seals 110,112 and contractor 130,132, so first and second sidewalls 102,104 of sack 100 keep sealing and sack can keep leakproof along periphery.Recess can provide the vision indication for the position of sack opening to the user, and can help to reduce the amount of making the necessary thermoplastic material of sack.

With reference to figure 2, produce throat 140 in the internal capacity that exists in sack 100 106 of contractor.Set level when measuring when sack 100, the width 142 of throat is less than the width 126 of opening 124.When first and second sidewalls 102,104 are separated when opening sack 100 and internal capacity 106 is opened, the diameter or the upperlimit that stride across internal capacity are littler than the position under the throat in internal capacity in the zone corresponding to throat 140.

With reference to figure 3, in sack 100 is inserted into tube 150 and top 120,122 152 last times of upper edge of being folded in tin, sack is outwards routed up from the inboard on the edge corresponding to the part of throat 140.In example embodiment, tube 150 is formed the vertical rectangular configuration that has square cross section, but sack is used to be used as the lining of the refuse tube with Any shape.The size of throat 140 can equal or be slightly less than the outer perimeter of measuring around the opening of tube 150 154 roughly.Throat can have interior girth 156, and interior girth 156 can be the twice of width 142.In first instance, the girth 154 of tube can be that the girth 156 of about 44 inches (112cm) and throat can be about 41 inches (104cm).In second instance, the girth 154 of tube can be that the girth 156 of about 58 inches (147cm) and throat can be about 55 inches (140cm).In the 3rd instance, the girth 154 of tube can be that the girth 156 of about 85 inches (216cm) and throat can be about 82 inches (208cm).Therefore, the throat 140 that is formed by contractor can closely cooperate and clamping around the periphery of tube 150.This helps prevent sack to fall into tube, in the time of especially in refuse and Other Waste article are placed into and accumulate in lined tube.

Sack can comprise that other characteristics are fixed on the rubbish shoot helping.For example, with reference to Fig. 1 and 2, sack 100 can be formed with pattern 170, and pattern 170 forms or be applied to basically in first and second contractors 130, first and second sidewalls 102,104 that extend between 132.Pattern 170 can partially or fully extend between contractor.Pattern 170 can provide the extensible characteristic that maybe can surrender to sack in throat region.The instance of this pattern and similar characteristics is in United States Patent(USP) No. 6,139,185; The open No.2004/0134923 of U.S.'s publication; United States Patent(USP) No. 6,394,651; United States Patent(USP) No. 6,394,652; United States Patent(USP) No. 6,150,647; United States Patent(USP) No. 6,513,975; With US Pat 6,695, be disclosed in 476, the full content of each of these applications is all incorporated this paper by reference into.

With reference to Figure 4 and 5; Pattern 170 can form a plurality of extensible or securable net structures (networks), and the thermoplastic material that is generally plane, sheet of first and second sidewalls can be pleating together according to the mode of the wrinkle of series of parallel or folding line in net structure.These comprise can be corresponding to a plurality of first areas 172 and a plurality of second areas 174 that form rib-shaped piece of the plane sheets of sidewall, and rib shape unit piece can be from the plane of first area outstanding and look it is to become pleat perhaps to collapse upon together when being in not tensioning state shown in Figure 4 the time together.When applying pulling force, shown in arrow among Fig. 5 176, thereby the second area of rib shape can be stretching or the geometry deformation first and second zones roughly coplane that can become each other.The whole zone that pattern is increased to sidewall thus can stretched or elongate to this action of tearing pleat open.

The thermoplastic material that pattern 170 puts on wherein can present shape memory, and shape memory makes first and second zones turn back to the geometric configuration of not tensioning state shown in Figure 4 when removing any power that applies.Therefore sack 100 can present the interior resilience or the DE in zone of throat 140.Get back to Fig. 3 and carry out reference, when using, pattern 170 can stretch or open throat 140 so that sack can be folded on the antelabium or edge of rubbish shoot 150.The resilience relevant with pattern can make throat 140 thus sack 100 is fixed and held in the tube around the outer perimeter contraction or the shrinkage of tube 150.Though in example embodiment, pattern 170 is shown as only is applied as contractor 130, stripes between 132, pattern can be arranged in other zones of bag sidewalls 102,104 in other embodiments.
