Patent number: 5597022Abstract: A flexible bag is loaded in at least two stages utilizing a loading ring of rigid plastic material having a height less than its diameter and having a height less than approximately one-half the height of the trash bag. The bag is inserted into the loading ring presenting an upper bag section surrounded by the ring section, and is filled with refuse, the lower section of the bag being in a collapsed condition beneath the ring. The ring an upper bag section are then manually shifted upwardly causing the refuse to drop by gravity into the bag lower section, after which the upper bag section is again filled with refuse material, and the loading ring is either removed depending on the bag size, or the loading ring together with the upper bag section is again shifted upwardly to present another unloaded upper bag section which is again filled with refuse. A two-stage or a three-stage loading operation is effected.Type: GrantFiled: September 19, 1995Date of Patent: January 28, 1997Inventor: Richard F. Reifers

Patent number: 5292017Abstract: A child resistant package includes a snap-on closure of rigid and stiff material on a container having a neck finish with an annular locking rib having at least one notch. The closure has a locking lug extending radially inwardly from its skirt in alignment in a fire position with the notch upon rotation of the closure to permit removal of the closure when in the fire position. A finger tab extends radially outwardly from the skirt in alignment with the locking lug, and the skirt has rib structure extending radially inwardly from the skirt circumferentially spaced from the locking lug. The locking rib and rib structure having coacting cams for resiliently expanding the skirt upon snap locking the closure to the neck finish and upon removal of the closure. The locking lug and the rib structure are interengaged with the locking rib upon snap locking and the rib structure becomes disengaged from the locking rib upon removal of the closure.Type: GrantFiled: January 26, 1993Date of Patent: March 8, 1994Assignee: Calmar Inc.Inventor: Richard F.

Patent number: 4448344Abstract: An egg cell base is provided to create softened areas of egg contact. The base has a center area which creates a softened cushion for egg contact and also creates a gap to shield the eggs from contact with the surface upon which the egg carton rests. Internally, the bottom is provided with a crater construction which helps distribute contact over a larger shell area, and also helps locate and hold the egg tip in place. Surrounding the central area are foot areas of greater thickness which provide strength for stacking. The ring cushion also is capable of providing an accordian motion upward to accommodate high eggs that may bulge the cover of the carton stacked therebelow during shipment.Type: GrantFiled: September 1, 1982Date of Patent: May 15, 1984Assignee: Diamond International CorporationInventors: Henry A.
