A dentifrice closure on a dentifrice tube can emit a signal upon the opening of the closure to dispense some of the dentifrice. The closure is comprised of a base portion to attach the closure to the dentifrice tube and a lid portion that closes the dispensing opening of the dentifrice tube and which contains switch timer and signal generator. The signal generator can be a light, but preferably is a sound generator, and most preferably a music generator. Upon the lid being opened, a switch activates the timer which in turn activates the signal generator. Regardless of the position of the switch after a lid opening (the lid can be quickly closed) the signal will be emitted for a set period of time.

Flip-cap closure

The container of this invention has an increased strength in compression. When filled and with a closure the containers can withstand greater compressive force without a resulting deflection. This permits the use of a lighter weight and less costly shipper carton. The containers have a substantially rigid base, and except for rigidifying recesses, a substantially planar base. Further, the sidewalls of the container are substantially devoid of recesses and projections, and particularly, in the region of the base of the container. In addition, the sidewalls have a slight outward taper from an area at an upper part of the sidewall to the base of the container.

Enhanced strength container

A method of molding a blister for a display package wherein there is provided a plurality of mold units, each mold unit having a base, a first surface extending from the base, a second surface adjacent to the first surface and forming with the first surface an angle less than 90.degree., providing a planar plastic sheet and orienting the mold unit so that the first surface is essentially normal to or forms an angle about equal to or less than 90.degree. to the plane of the plastic sheet, with the proviso that the angle formed by the plane and the second surface is less than 90.degree., providing wire filaments for physically compressing upon the planar sheet and between each of the plurality of mold units and for segregating the plurality into rows of individual mold units, further conforming the plastic sheet to the shape of the mold unit, whereby a shaped plastic sheet is produced, and removing the shaped plastic sheet from the mold unit according to a translation direction substantially identical to the translation direction of the step of conforming the plastic sheet to the shape of the mold unit.

Vacuum forming method for manufacturing self-supporting display package

The invention relates to self-supporting, vertically free-standing display packages for displaying a product. More particularly, the invention relates to a blister pack display package having a preformed product closure attached to a paperboard back and provided with a unitary support structure. Another aspect of the invention concerns its manufacture by molding a plastic sheet into said blister package in such manner as to advantageously strengthen said unitary support structure along the edge of its contact with the surface on which it stands.
