Abstract
A structure is provided in a container having a fluent material, such as a liquid or powder, to be selectively dispensed therefrom, and a simple, quick opening means for the container which may be effected without the need for special tooling such as a can opener. In one form, an opening is provided in the wall of a metal, plastic or paperboard container through which the contents thereof may be dispensed. Simple closure means is provided in the form of a short plastic or metal strip which is sealed to the container around the opening to close off same. The strip contains an unsealed tab portion at one end thereof which normally lies flat against the container wall and may be easily lifted by hand and pulled to break the seal with the wall of the container and to expose the opening.
Claims6
A container assembly comprising:
- a container defining a housing with a thin wall enclosing and containing fluent contents to be selectively dispensed therefrom,
- an opening formed in a portion of said container wall, and
- a closure disposed across and extending beyond said opening,
- said closure comprising an elongated flat strip of relatively thin flexible sheet material,
- a first portion of said elongated flat strip sheet material being welded against and sealed to the outside surface of said container along a weld line formed between said flat strip and said container wall which weld line completely surrounds said opening in said container wall,
- a second portion of said flat strip of thin sheet material defining said closure and comprising one end thereof, said second portion of flat strip material being unattached to said container wall and being of sufficient length to permit it to be grasped betweed the thumb and forefinger of the hand and to be pulled thereby outwardly from said container wall to permit the welding defined by the circumscribing weld line between said first portion and the outside surface of said container wall to be destroyed whereby the entire strip closure may be removed from said container wall and the opening in said container wall may be uncovered to permit the contents of said container to be dispensed through said opening.
