Abstract
A food storage container for dry or liquid foods and other open air perishable products provides a leak-resistant seal when the lid is in a closed position and easy pouring of contents when in the open position. The container is easy to open, employing rocker points to allow for a rocking acting effective to release the lid from a closed position when a downward force is exerted upon an upper surface of the lid thereby providing an effective opening for pouring. A leak-resistant seal is achieved through the use of a plug section of the lid having a continuous outer peripheral surface which effects a close conforming fit with a similarly positioned surface area on the container body in a continuous and positive manner.
Claims20
An easy-opening, leak-resistant liquid storage container, comprising:
- (a) a container body produced from a styrene-acrylonitrile copolymer, said container body having pour-accommodating means, said container body having substantially upright walls, said walls having an upper rim portion and a bottom portion, said upper rim portion having an inner surface and an outer surface;
- and
- (b) a removable thermoplastic lid, said lid including:
- (i) a cover section having an upper surface and a lower surface;
- (ii) a plug section integral to said lower surface of said cover section, said plug section having an outer peripheral surface adapted to substantially conform to the inner surface of said upper rim portion of said container body walls for providing a close conforming fit when said lid is installed on said container body;
- and
- (iii) a lip integral to said cover section, said lip spaced apart from said outer peripheral surface of said plug section, wherein said lip combine with said lower surface of said cover section and said outer peripheral surface of said plug section to form a track, said track having a pair of rocker points;
- whereby said rocker points are effective to release said lid from a closed position when a downward force is exerted upon the upper surface of said cover section of said lid.
An easy-opening, leak-resistant liquid storage container, comprising:
- (a) a container body produced from a styrene-acrylonitrile copolymer, said container body having substantially upright walls, said walls having an upper rim portion and a bottom portion, said upper rim portion having an inner surface and an outer surface;
- and
- (b) a removable thermoplastic lid having pour-accommodating means, said lid including:
- (i) a cover section having an upper surface and a lower surface;
- (ii) a plug section integral to said lower surface of said cover section, said plug section having an outer peripheral surface adapted to substantially conform to the inner surface of said upper rim portion of said container body walls of providing a close conforming fit when said lid si installed on said container body;
- (iii) a lip integral to said cover section, said lip spaced apart from said outer peripheral surface of said plug section, wherein said lip combines with said lower surface of said cover section and said outer peripheral surface of said plug section to form a track, said track having a pair of rocker points;
- and
- (iv) a pour orifice located in a portion of said plug section of said lid, said pour orifice positioned so as to be exposed when said lid is in a fully open position;
- whereby said rocker point are effective to release said lid from a closed position when a downward force is exerted upon the upper surface of said cover section of said lid.
An easy-opening, leak-resistant food storage container, comprising:
- (a) a thermoplastic container body having substantially upright walls, said walls having an upper rim portion and a bottom portion, said upper rim portion having an inner surface and an outer surface;
- and
- (b) a removable thermoplastic lid, said lid including:
- (i) a cover section having an upper surface and a lower surface;
- (ii) a plug section integral to said lower surface of said cover section, said plug section having an outer peripheral surface adapted to substantially conform to the inner surface of said upper rim portion of said container body walls for providing a close conforming fit when said lid si installed on aid container body;
- and
- (iii) a lip integral to said cover section, said lip spaced apart from said outer peripheral surface of said plug section, wherein said lip combines with said lower surface of said cover section and said outer peripheral surface of sis plug section to form a track, said tack having a pair of rocker points;
- whereby said rocker points are effective to release said lid from a closed position when a downward force is exerted upon the upper surface of said cover section of said lid.
