Claim 3

A dispensing closure for use with a container having a wall provided with an opening, said dispensing closure comprising: a. a body member; b. a flexible wall member extending between portions of said body member and being integral therewith; c. a spout member having a through dispensing opening and being integral with said flexible wall and moveable between first and second positions wherein said wall flexes to permit movement of said spout member; d. biasing means cooperating with said spout member for biasing same to said first position and urging movement of said spout member from said second position to said first position; e. retaining means cooperating with said spout member adjacent a free end thereof and releasably retaining said spout member in said second position; f. means on said body member adapted for securing same to a container body to close an opening therein; g. seal means on said retaining means and engaging said spout member for closing said dispensing opening when said spout member is in said second position; h. said flexible wall being on opposite sides of said spout member with said biasing means including an increased thickness portion integral with said flexible wall and extending from opposite sides of said spout member to said body member; i. said spout member being molded in a generally upstanding position with said upstanding position being said first position whereby movement of same from said first position to said second position induces a torque in said increased thickness portion and release of said spout member allows the torque to be released and return said spout member to said first position; and j. said body member, flexible wall, spout member and retaining means being integral and molded from a resilient plastic resin.

Claim 4

A dispensing closure for use with a container having a wall provided with an opening, said dispensing closure comprising: a. a body member; b. a flexible wall member extending between portions of said body member and being integral therewith; c. a spout member having a through dispensing opening and being integral with said flexible wall and moveable between first and second positions wherein said wall flexes to permit movement of said spout member; d. biasing means cooperating with said spout member for biasing same to said first position and urging movement of said spout member from said second position to said first position; e. retaining means cooperating with said spout member adjacent a free end thereof and releasably retaining said spout member in said second position; f. means on said body member adapted for securing same to a container body to close an opening therein; g. seal means on said retaining means and engaging said spout member for closing said dispensing opening when said spout member is in said second position; h. said flexible wall being on opposite sides of said spout member with said biasing means including an increased thickness portion integral with said flexible wall and extending from opposite sides of said spout member to said body member; i. said spout member being molded in a generally upstanding position with said upstanding position being said first position whereby movement of same from said first position to said second position induces a torque in said increased thickness portion and release of said spout member allows the torque to be released and return said spout member to said first position; and j. said body member, flexible wall, spout member and retaining means being integral and molded from a resilient plastic resin.

Claim 5

The dispensing closure as set forth in claim 2 wherein: a. said retaining means includes a catch member having portions thereof engageable with portions of said spout member adjacent the free end thereof, said spout member being releasable by application of a predetermined amount of force to one of said catch member and said spout member.

Claim 6

A dispensing container comprising: a. a hollow container body having bottom, side and top walls, said top wall being flexible; b. a spout member having a through dispensing passage and being integral with said flexible wall, said spout member and flexible wall being molded with the spout member in upright discharging position, said spout member being spaced from said side walls; c. said flexible top wall having elongate torque member portions of increased thickness extending in opposed relation from the spout member to said side walls defining an axis of pivotal movement of said spout member from said discharge position to a second position substantially overlying a portion of said flexible wall, said flexible top wall being divided into two portions which are positioned on opposite sides of the spout member, said torque member portions being integral with and positioned between said two top wall portions and connected to the spout member and side walls and having resilient biasing action urging said spout from said second position to said discharge position, said pivotal movement of said spout being in a plane normal to the torque member portions, said spout member overlying a portion of one of said two wall portions when in said second position, and a retaining member selectively cooperating with said spout member adjacent a free end thereof when in said second position for releasAbly retaining said spout member in said second position.

Claim 7

A dispensing container comprising: a. a hollow container body having bottom, side and top walls, said top wall being flexible; b. a spout member having a through dispensing passage and being integral with said flexible wall, said spout member and flexible wall being molded with the spout member in upright discharging position, said spout member being spaced from said side walls; c. said flexible top wall having elongate torque member portions of increased thickness extending in opposed relation from the spout member to said side walls defining an axis of pivotal movement of said spout member from said discharge position to a second position substantially overlying a portion of said flexible wall, said flexible top wall being divided into two portions which are positioned on opposite sides of the spout member, said torque member portions being integral with and positioned between said two top wall portions and connected to the spout member and side walls and having resilient biasing action urging said spout from said second position to said discharge position, said pivotal movement of said spout being in a plane normal to the torque member portions, said spout member overlying a portion of one of said two wall portions when in said second position, and a retaining member selectively cooperating with said spout member adjacent a free end thereof when in said second position for releasAbly retaining said spout member in said second position.

Claim 8

The dispensing container as set forth in claim 4 including: a. seal means on said retaining member and engaging said free end of said spout member when same is in said second position for sealing said dispensing passage; b. said spout member having a length such that engagement of said seal means with said spout free end stresses said torque member positions to hold the spout member and retaining member engaged in said second position.

Claim 9

The dispensing container as set forth in claim 4 wherein: a. said flexible top wall being separate from the remaining container defining walls with said flexible top wall overlying and closing a container opening defined by an edge of at least one of the remaining container walls; b. means on said flexible top wall and cooperating with said container wall defining said container opening for securing said flexible top wall in closing relation to said container opening; and c. said flexible top wall having an undulating contour.
