Abstract
Mold apparatus for molding a weighing funnel that has a large diameter central segment, and a hole at each end that is smaller than the central segment. A 2-part core is used, the two parts together forming the size and shape of the article to be molded, and to remove the core from the molded article, the parts are withdrawn individually through a hole at the end of the article.
Claims5
A weighing funnel comprising
- a single, integral, one-piece, molded, tubular member having a central longitudinal axis,
- the tubular member having a main segment and first and second end openings each smaller than the main segment,
- the tubular member having a resting element on its outer surface of such shape relative to the remainder of the outer surface as to be capable of maintaining the tubular member in a stable position on a supporting surface with said axis parallel to the supporting surface, and
- the tubular member having segments forming lower edges of the openings at levels above the supporting surface when the tubular member is resting on the supporting surface, whereby to confine in the tubular member a quantity of loose material introduced therein,
- the main segment is nearly cylindrical in shape, but has a flat side forming said resting element,
- the main segment is the largest part of the tubular member in diametric direction,
- the second end opening lies in a plane cutting through the cylindrical part of the tubular member and extending obliquely endwise away from the first opening beyond the main segment, thereby forming an end surface extending diametrically inwardly from the flat side and forming said lower edge of the second opening.
