Abstract: A two part plastic container for food products is provided having a main body and a base for being attached to the bottom of the body. The body has a frustoconical sidewall with a radial bottom rim and the base has a shorter frustoconical sidewall with a radial bottom rim. The rims are advantageous in that they allow stacks of the container bodies and bases to be processed with container feeding equipment presently in use as the rims provide distinct structure for being fed by the mechanical devices of the equipment. An energy director area is provided between the rims for ultrasonically attaching the container body and base. The container body has a smooth sidewall over substantially its entire extent without indentations or bumps for maximizing the printing area thereon.

Abstract: An improved container assembly for the storage and dispensing of pre-moistened towelettes is provided. The assembly includes a container and a multi-function cap. The cap matably engages the upper end of the container and further provides an additional storage area for the storage and retention of partially used towelettes. The cap also provides a relatively airtight seal to keep the towelettes moist and prevent them from prematurely drying out. A flexibly web in the cap enables the towelettes, connected to one another by perforations, to be pulled through the web of the cap. An individual towelette is separated from the roll with a sharp jerk or tub which tears the towelette along the perforation and leaves the remaining towelette extending partially through the web. An area underneath the top closure member of the cap and the web provides a sealed area for the storage of partially used towelettes.

Abstract: Disclosed is a mold and a method for injection molding plastic components in which the conventional horizontal parting line is replaced with an angled parting line to allow for utilization of increased packing pressure without the formation of flashing. By positioning at least the portion of the parting line extending immediately outward of the mold cavity at an acute angle with respect to the separating direction of two adjacent mold sections, the separation distance between adjacent mold sections can be increased above a critical flashing distance while maintaining the span at the angled parting line below the critical flashing distance to preclude flash formation. Specifically, the span at the angled parting line increases in proportion to the sine of the angle between the angled parting line and the separating direction. Accordingly, higher pressures can be employed to allow for increased production rates with angled parting line molds of the present invention in comparison with conventional molds.
