Abstract: A method is described for reducing the amount of aldehyde liberated from aldehyde-containing resins during the production and subsequent use of products prepared with the resin by admixing bisulfite salt scavengers therewith. A method is also described for reducing airborne aldehydes from the environment by placing aqueous solutions of bisulfite salts in the aldehyde-containing environment.

Abstract: A closure for a cylindrically shaped ice cream carton or the like includes a unitary circular shaped plastic lid provided with a depending skirt portion. The top surface of the lid includes an upwardly and inwardly extending concentric bead inwardly tapered on its outer surface to enhance retaining a plurality of similar lids in stacked relation. The bead rigidifies the lid, enhances nested stacking of lid-carton assemblies and provides a locking and protective recess for labels containing printed indicia. The skirt of the lid includes a lower outwardly tapered inner surface portion for mating with the outer surface of the bead to enhance nested stacking of the lids and to enable the lid to be grasped and readily removed from tight fitting engagement with an ice cream carton. An upper, inner annular recessed portion of the lid skirt accommodates expansion of the ice cream carton without the lid popping off the carton.

Abstract: An improved counter display of the type having a back panel, a base support and a face panel for holding pencil-like objects, the improvement comprising means for hingedly coupling the base support to the lower end of both the face panel and the back panel, and means for hingedly attaching at least a portion of the face panel to an upper portion of the back panel in an overlapping relationship such that when the base support is pivoted about the coupling hinges to form a base, the face panel is hingedly moved perpendicularly away from the back panel to enable pencil-like objects to be mounted thereon.

Abstract: A carton for suspending an article within the carton and a blank for forming same has a collapsible arrangement for automatically forming the suspension support. This arrangement includes two parallel bridge panels, each of which is hingedly coupled at its opposite side edges to the front and back panels at locations spaced from the side panels of the carton. The upper edges of the bridge panels form a support surface which is substantially perpendicular and between the carton panels for supporting an edge of a cap of an article to suspend the article between the bridge panels and within the carton. Front flaps pivotedly mounted at the opposite side edges of the front panel may be formed in the front panel and located behind the cap of the article to create a shadow effect.

Abstract: An article carrier and a blank for forming the same is provided having an integral carrying handle which is configured to relieve local stress in the area of the handle which would otherwise tend to tear or deform the paperboard material from which the carrier is formed. More particularly, a cut line is provided in a top panel of the carrier which defines a handle tab that pivots about a hinge line. In addition, the cut line includes two straight portions which extend beyond the top panel into the opposed side panels of the carrier and are contiguous with a pair of stress relieving apertures also disposed in the opposed side panels.

Abstract: A paint applicator for direct roll coating of textured panels or sheet-like members comprises a core, a layer of fibrous web material disposed over the core, a protective plastic tube member disposed around the layer of fibrous web material, and a layer of woven material disposed over the protective tube member. The fibrous web allows for uniform application of the paint film due to its softness and ability to follow contoured surfaces. The protective tube member prevents paint from penetrating the fiber web. The woven material carries the paint on the roll applicator.

Abstract: A printing plate for printing a linear bar symbol code includes a body portion which is adhesively bonded to a mylar mounting sheet that is secured to a typical printing cylinder core. Integral with the body portion of the printing plate is a substantially rectangular frame member having opposed side members and end members which enclose a central channel. Disposed within the channel and integral with and connecting the opposed side members are a plurality of spaced bar members which define the linear bars of a symbol code. One of the side members includes a plurality of recesses having the configuration of numbers disposed in relief. The machine-readable linear bars correspond to the human-readable numbers of a symbol code. The frame member which constitutes a majority of the printing contact surface of the plate is raised the same distance from the body portion as the linear bar members such that the contact surface of the frame is flush with the contact surfaces of the bar members.

Abstract: A two part paperboard container having adjustable vents is described and is intended for use with a sublimable composition. The container consists of an inner tubular member and an outer tubular sleeve member, both of a truncated, conical configuration. The inner tubular member, which is adapted to receive the sublimable composition, is disposed within the outer sleeve member. The outer surface of the inner member is in frictional engagement with the inner surface of the outer sleeve member which functions to seal the carton. The inner member may be rotated relative to the outer sleeve member to at least partially align apertures provided in the upper cover portions of the tubular members, thereby exposing the composition to the air enabling it to sublime. Continued relative rotation of the tubular members will reset the apertures in the upper cover portions in a nonaligned position, thereby resealing the container.

Abstract: In the bleaching of wood pulp using the conventional CEH sequence with subsequent oxidation stages, the third stage (H) is replaced by peroxide oxidation (P) to a brightness level of 35-50 GE. Final brightness levels of 70-88 GE are attained using no greater amounts of chemicals in the subsequent stages than are required in the conventional CEHDH process. The temperature in the P stage is between 120.degree. and 170.degree. F.

Abstract: A corner post made of folded corrugated paperboard is inserted into the corner areas of cartons containing, for example, large appliances, such as stoves, refrigerators, washing machines, or the like. The corner post is a multi ply device which ensures that there will be adequate space between the appliance and the carton wall, and which provides strength for the carton so that multiple filled cartons can be stacked on top of each other. The post is provided with fold lines which are made up of alternating cuts and scores to provide for easy folding of the post. The post is machine folded and glued to a flattened form which is suitable for bulk shipment. The post is easily transformed from the flattened to the erected form and inserted into the corner areas of the cartons.
