Abstract: A containment and disposal bag for human bodily fluids is disclosed which includes a bag having a hollow interior and a top at least partially open to receive the bodily fluids; preferably a funnel structure within the bag to channel said bodily fluids into the interior and to restrict expulsion of bodily fluids from the interior prior to sequestration; a hydrophilic material within the bag which is rapidly gellable upon contact with the bodily fluids in the bag, the gellation serving to essentially completely sequester the bodily fluids and prevent it from thereafter being expelled from the bag; and a closure to close the top of the bag after introduction of the bodily fluids into the bag. The hydrophilic material is commonly a polymer which is activated upon contact with the water-based bodily fluids and which gels rapidly (normally within thirty seconds or less) to sequester the bodily fluids.

The loop handle is secured to the bag panels and is provided with a frangible region which can be broken to form two separate handle portions. The handle portions are releasably joined by mating slide closure structure. The slide closure joint can be peeled away by pulling the handle portions apart thereby providing access to the folded top end of the bag. The top end of the bag may be provided with perforations which may be broken to gain access to the bag contents. The bag may be resealed by means of the handle slide closure.

Abstract: Large size packagings of napkins, paper rolls, quilts etc. normally appear as tight plastic sheet packings of a block-like shape. As a carrier handle is used a strong strip of sheet material which extends across a side panel of the packing, what is disadvantageous for the visual impression of the packing. A carrier handle cannot be formed direct in the packing sheet, as the packing will then no longer be dust proof. A handle is formed wherein inside the handle area, a barrier layer is provided in order to make the packing dust proof. Preferably a carrier handle strip portion is prepared between easily breakable weakening lines, whereby the handle panel of the packing may show a high quality stamp regardless of the handle.

Pleats defined in each bag wall extend vertically downward from the mouth-forming edges. The pleats, upon expansion by direct finger engagement therewith or the application of outwardly directed opposite forces on the opposed ends of the mouth portion of the bag, cause a lateral separation of the edges for initiating opening of the bag mouth. The bag may be vertically partitioned into lateral compartments with at least one wall of each compartment including a mouth-opening pleat therein.

The sinusoidal rim of the rear wall terminates either above or below the rim of the front wall in the lateral weld seams. A process for the production of the shopping bags by sinusoidal cutting apart of a film ply of a tubular sheet involves a series of sequential operation at successive stages or stations.

Abstract: A carrier bag of heat-sealable plastic film has a front panel joined along side edges by weld lines to a rear panel. The top ends of the panels are joined by an inwardly foldable gusset which is integral in one piece with the panels. The gusset is joined at the ends to the weld lines such that when the bag is in expanded position, the gusset opens to form a top panel of the bag with inner triangular gussets at the ends thereof lying adjacent double-layer triangular film portions joined through the apexes thereof by the weld lines. A cut-out handle for the bag is formed in one of these double-layer triangular portions. The handle may be further reinforced by joining the two film layers of the double-layer portion by means of a V-shaped weld line having the apex on a side edge weld line and extending upwardly on each side of the cut-out handle.

Abstract: A handle web (14) is heat sealed to the gusset end of a bag web (10). The bag is a bottom filled top gusset bag which assumes a carton shape when filled. The handle web (14) has a central portion which extends over the gusset (18). Substantially D-shaped hand openings (16, 18) are formed in the handle web (14). These openings (16, 18) have inwardly-directed arcuate sides (60, 62) and substantially flat outwardly-directed sides (64, 66). Rounded corners (68, 70, 72, 74) are formed where the arcuate sides (60, 62) meet the flat sides (64, 66). This construction results in a four-sided stretching of the handle web when under load, along smoothly curving arcuate paths, providing good stress distribution in the handle web material and the elimination of tear-inducing stress concentrations.

The handle is provided by making a continuous curvilinear slit in the flap, the ends of the slit comprising a pair of inwardly. open arcs. The uppermost ends of the inwardly open arcs are inwardly extended until they transition into a centrally located, upwardly concave arc which connects the two inwardly open arcs to one another.

Abstract: A quick packing, facilitating transport and display in large-scale distribution outlets, for products such as flue-brushes for cleaning square-, rectangular-or circular-section flues, comprises two rigid side elements, made of material such as corrugated cardboard or other synthetic material, of rectangular form of which the width is at least equal to the largest dimension of said products. The bottom of the packing, connected to the two side elements, is provided with two side flaps of sufficient height, automatically cooperating, by adequate folding means, with the two side elements, becoming perpendicular thereto. The assembly thus formed is in the form of a trough adapted to ensure lateral holding of the products. In the top of the packing it comprises means for rapidly assembling the side elements previously brought "edge to edge", as well as a cut-out on each of the side elements to form a handle for transporting purposes.

Abstract: The present invention relates to thermoplastic bags which are characterized by two perforated tabs symetrically attached to the front and back walls at the mouth of the bag. Using a sculptured bag or any of several thermoplastic bag structures currently in use (handled or flush-cut; gussetted or flat), the configuration of the two tabs is such that it enables the user to easily open and load the bag while the mouth remains open and the bag in place. Additionally, the placement of the two tabs permits easy loading of a unitary pack on dispensing holders, including armless stands, resulting in more efficient use of time and space by retail users. The placement and scallop design of the tab perforations create stress transfer tips which distribute stress away from creases and slit-seals at the open mouth, preventing tearing or zippering at the mouth of the bag where stress concentration is most likely and permitting greater use of slit-seals and corresponding reduced costs of manufacture.
