A central portion of the top of such tube is provided with suitable product receiving openings which may open into a receptacle or which receive drink cups. At one or more ends of the tray, there is a compartment which is defined by an end of the initial tube which is pivoted from a longitudinal position to an upstanding position. The tray may have one or more internal stiffeners to prevent the collapse thereof when in tube form and stacked. Numerous embodiments are envisioned although only a limited number of alternatives is specifically disclosed.

Abstract: A basket carrier of the type including a base having a plurality of handles projecting upwardly therefrom, the handles also functioning as partitions so as to divide the base into a plurality of individual spaces for receiving cups, bottles and the like. The same basic basket carrier can be formed from two different blanks. It has been found that by providing two different blanks, a full nesting of the blanks may be obtained so that the blanks may be formed from a web with substantially no loss, thereby reducing the amount of paperboard required to form the blanks. The resultant carriers differ primarily in that one carrier includes one double handle and two single handle arrangements and the other carrier has two double handle arrangements. The carriers differ also in the manner in which the various portions are connected together by way of different arrangements of glue flaps.

Abstract: An applicator for applying elongated strip members to a moving member. The applicator is particularly adapted to apply handle assemblies to moving closure panels of containers such as cartons. Hot melt adhesive stripes are applied to the moving closure panel and thereafter a handle assembly is applied over the hot melt adhesive. The apparatus includes, in addition for moving containers at a uniform rate and spacing, a hopper overlying the path of movement, a picker device for periodically withdrawing a lowermost handle assembly from the hopper, and a combined guide and presser member for first receiving in guided relation an end of a withdrawn handle member remote from the picker device, and thereafter pressing the handle member against the adhesive strip beginning at the right end of the withdrawn handle assembly.

Abstract: This relates to a multicell carrier which is advantageously formed from two separate generally rectangular blanks as opposed to a single generally L-shaped blank. By forming the carrier from two separate blanks, each of which is generally rectangular, a maximum board usage may be obtained and at the same time board is available, without waste, for forming handle reinforcing flaps. In addition, by providing two separate blanks and effecting the simultaneous folding of the two blanks, although the two blanks must be joined in the forming of a carrier, greater glue and folding speed is obtainable as compared to the forming of a like carrier from a single L-shaped blank.

Abstract: A method of treating chemical process water which contains dissolved solids, usually of a biodegradable organic nature. According to the invention, the dissolved organic solids, which are objectionable because they cause process equipment corrosion, undesirable product and process odors and pollution, are treated with ultraviolet light. The light treatment causes dissolved materials of relatively simple chemical structure to react and create more complex, less soluble materials which can easily be removed from the system as they become less soluble. The method is applicable to papermaking and numerous other industrial processes using large quantities of process water.

Abstract: This relates to cartons or packages which are sealed in a manner wherein they cannot be opened no matter how careful one is without giving an indication of tampering. In one form of the invention, an outermost closure panel is provided with a tuck flap which extends down between inner and outer panels of a double wall carton body wall and the inner surface of the tuck flap is bonded to the exterior surface of an inner panel to provide an inaccessible bond. Panels of cartons which are bonded together and have an accessible seam may be provided with an arrangement of weakening lines so that if one attempts to destroy the bond using a knife or razor blade, the exposed outer panel will give evidence of rupturing and thus indicate tampering even though the two panels are later resealed.

In addition, each secondary flap carries remote from the associated secondary locking tab a separator tab which projects into the interior of the carton and is disposed between items of two adjacent rows to separate such items.

Abstract: An improved mounting system for stripper pins used in separating pre-cut areas from folding carton blanks. A system of rails, tracks, holders and brackets is provided which facilitates easy adjustment of the stripper pin location and reduces preparation time. An important feature is that the horizontal surfaces of the pin mounting brackets are of minimal area so as to prevent accumulation of scrap pieces separated from paperboard blanks from accumulating on the pin brackets and tracks. This minimizes manual clean-up work and press downtime.

Abstract: A method of treating papermaking white water which contains dissolved solids, usually of a biodegradable organic nature. According to the invention, the dissolved organic solids, which are objectionable because they cause process equipment corosion, undesirable product and process odors and water pollution, are treated with ultraviolet light so as to lower their concentration and eliminate these problems. The light treatment causes material of relatively simple chemical structure to polymerize into more complex, less soluble materials which can easily be removed from the system as they become less soluble. The method is applicable to papermaking and other industries process using large quantities of process water. The treatment cell, which preferably operates on clarified white water, may be placed in series with the process while water flow or in parallel therewith, and can be operated as a continuing treatment process or as a intermittent treatment process.
