Abstract
A pouring spout for a container of from one pint to one gallon in size, having a discharge opening therein. The pouring spout comprises a tapered plug, such as a stopper, to fit in the opening and has a hole with which one end of an elongated tube is connected for discharge of the contents. The exterior of the plug or stopper is provided with an elongated groove through which air is admitted into the container as liquid is discharged therefrom. The tapered plug or stopper has stepped periphery provided by a series of ribs to cause tight fit engagement with the opening in the container of varying sizes.
Claims4
A pouring spout for a container having a discharge opening for pouring liquid contents therefrom, said spout comprising:
- a plug having inner and outer ends and an opening therethrough extending from the inner end to the outer end for discharging contents from the container through said plug opening;
- said plug having an outer periphery including an air-admitting external groove formed therein to admit air to the interior of the container during discharge of the contents therefrom through said plug opening;
- an elongated discharge tube connected at one end with the plug opening to conduct contents from said plug opening;
- said plug being formed of yieldable material and having an outer periphery formed by a plurality of circumferentially disposed resilient ribs, said ribs being spaced in a direction from said outer end to said inner end of said plug and being of gradually decreasing size from said outer end to said inner end to define a ribbed periphery which tapers toward said inner end to allow said plug to fit container discharge openings of various sizes, each rib including:
- an outer surface extending away from the longitudinal axis of said plug opening in a direction toward said inner end and forming an acute angle relative to the longitudinal axis of said plug opening so as to be compressed by, and in firm engagement with, said container discharge opening when said plug is installed therein;
- and
- a lateral side extending at an angle relative to said outer surface for engaging a lip of said container discharge opening to limit the insertion of said plug into said container discharge opening.
A pouring spout for a container having a discharge opening for pouring liquid contents therefrom, said spout comprising:
- a plug having inner and outer ends and an opening therethrough extending from the inner end to the outer end for discharging contents from the container through said plug opening;
- said plug having an outer periphery including air-admitting external groove formed therein to admit air to the interior of the container during discharge of the contents therefrom through said plug opening;
- an elongated discharge tube connected at one end with the plug opening to conduct contents from said plug opening;
- an elongated discharge tube connected at one end with the plug opening to conduct contents from said plug opening;
- said plug being formed of yieldable material, with said outer periphery being formed by a plurality of circumferentially extending resilient ribs, said ribs being spaced in a direction from said outer end to said inner end of said plug and being of gradually decreasing diameter from said outer end to said inner end to define a ribbed periphery which tapers toward said inner end to allow said plug to fit container discharge openings of various diameters, each rib including:
- an outer surface for gripping an inner portion of the container discharge opening, said outer surface extending away from the longitudinal axis of said plug opening in a direction toward said inner end and forming an acute angle relative to the axis of said plug opening so as to be compressed by, and in firm engagement with, said container opening when said plug is installed therein, and
- a lateral surface extending at an angle relative to said outer surface for engaging a lip of said container discharge opening;
- said tube extending through said plug and including a shoulder engaging a projection of said plug to retain said tube in said plug.
