Abstract
Abstract A molded plastic closure for a dispensing bottle for liquid or viscous material, which closure includes a body portion and a cap, the cap, being pivotally secured to the body along an integral hinge line, the cap having a button-like portion and the body having an opening, the distance between the hinge and the opening in the body being slightly less than the distance between the hinge and the button on the cap to provide a snap-lock closure which is leakproof when the cap is in place over the body and the button is stressed against the opening.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
A universal, plastic, one-piece, snap-type closure for a variety of containers of the type having a dispensing opening, the closure having a body-portion for mounting on the container adjacent its opening and also having a capportion, the body-portion having an orifice in a wall portion remote from the dispensing opening of the container, the cap portion having a dimple for sealing the orifice of the body portion, a unitary hinge having an axis and forming an integral connection between the body-portion and the cap-portion, the distance from the axis of the hinge to the orifice being greater than the distance from the axis of the hinge to the dimple, the cap-portion being arranged to pivot over the body-portion about the hinge so that the dimple fits over the orifice, the axis of the hinge being off-center and at one side of the body-portion, the wall portion in the body portion being approximately at a right angle to a line drawn between the orifice and the axis, inherent tension between the body-portion and the cap-portion causing a fluid-tight seal of dimple against orifice when the dimple and the orifice are in juxtaposition.
Claim 2
Dependent Claim
191 words
A universal, plastic, one-piece, snap-type closure for a variety of containers of the type having a dispensing opening, the closure having a body-portion for mounting on the container adjacent its opening and also having a capportion, the body-portion having an orifice in a wall portion remote from the dispensing opening of the container, the cap portion having a dimple for sealing the orifice of the body portion, a unitary hinge having an axis and forming an integral connection between the body-portion and the cap-portion, the distance from the axis of the hinge to the orifice being greater than the distance from the axis of the hinge to the dimple, the cap-portion being arranged to pivot over the body-portion about the hinge so that the dimple fits over the orifice, the axis of the hinge being off-center and at one side of the body-portion, the wall portion in the body portion being approximately at a right angle to a line drawn between the orifice and the axis, inherent tension between the body-portion and the cap-portion causing a fluid-tight seal of dimple against orifice when the dimple and the orifice are in juxtaposition.
Claim 3
Dependent Claim
22 words
The snap-type dispensing closure of claim 1 wherein the orifice is a large diameter opening adapted to receive thick viscous paste-type material.
Claim 4
Dependent Claim
