The spout includes a base, a chute, a closure, and a tear line. The base is adapted to be joined to a wall of a container, and defines an opening. The chute communicates with the opening. The chute has a first end at least partially surrounding the opening and a second end spaced from the first end. The closure is positioned to close the chute. The tear line defines a seal of the closure. The tear line is adapted to be broken readily, without relative rotation between the closure and the chute of the spout about an axis generally perpendicular to the base, to open the spout. The base, spout, closure, and tear line can be injection molded as one integrally formed piece. ## Claims ### Claim 1 A spout for a container, comprising: A. a base adapted to be joined to a wall of a container, the base defining an opening; B. a chute communicating with the opening, the chute having a first end at least partially surrounding the opening and a second end spaced from the first end; C. a closure positioned to close the chute; and D. a tear line defining a seal of the closure, the tear line being adapted to be broken readily at least in part by deforming the chute and without relative rotation between the closure and the chute of the spout about an axis perpendicular to the base, to open the spout; E. wherein the base, spout, closure, and tear line are injection molded as one integrally formed piece. ### Claim 2 (depends on 1) The spout of claim 1, further comprising a pull tab secured to the closure. ### Claim 3 (depends on 1) The spout of claim 1, wherein the base has an annular shape. ### Claim 4 (depends on 1) The spout of claim 1, wherein the closure is located at and closes the second end of the chute. ### Claim 5 (depends on 1) The spout of claim 1, wherein the second end of the chute projects outward from the base. ### Claim 6 (depends on 1) The spout of claim 1, wherein breaking the tear line to open the spout generates a sound providing audible feedback that the tear line was intact until the spout was opened. ### Claim 7 (depends on 1) The spout of claim 1, further comprising a vent to allow air to be introduced into the base opening after the spout is opened. ### Claim 8 (depends on 1) The spout of claim 1, wherein the tear line is between 0.05 and 0.2 mm thick, and the wall in which the tear line is formed is 0.4 to 0.8 mm thick. ### Claim 9 (depends on 1) The spout of claim 1, wherein the closure is dome-shaped. ### Claim 10 (depends on 1) The spout of claim 1, further comprising a boundary between the closure and at least one of the base and the chute, wherein a portion of the boundary defines an integral hinge. ### Claim 11 (depends on 10) The spout of claim 10, wherein a portion of the boundary between the closure and the chute defines an integral hinge. ### Claim 12 (depends on 10) The spout of claim 10, wherein a portion of the boundary between the closure and the base defines an integral hinge. ### Claim 13 (depends on 10) The spout of claim 10, wherein the integral hinge is inelastically deformable when the spout is opened, thereby causing the closure to normally remain open after the spout is opened. ### Claim 14 (depends on 1) The spout of claim 1, wherein the tear line provides a boundary between the closure and at least one of the base and the chute, allowing the closure to be removed from the spout. ### Claim 15 (depends on 14) The spout of claim 14, wherein the boundary between the closure and the chute is the tear line. ### Claim 16 (depends on 14) The spout of claim 14, wherein the boundary between the closure and the base is the tear line. ### Claim 17 (depends on 1) The spout of claim 1, wherein the chute has a closed cross-section. ### Claim 18 (depends on 1) The spout of claim 1, wherein the chute has an open cross section. ### Claim 19 A spout for a container, comprising: A. a base adapted to be joined to a wall of a container, the base defining an opening; B. a chute communicating with the opening, the chute having a first end at least partially surrounding the opening and a second end spaced from the first end; C. a closure positioned to close the chute; D. a tear line defining a seal of the closure, the tear line being adapted to be broken readily, without relative rotation between the closure and the chute of the spout about an axis perpendicular to the base, to open the spout; and E. first and second fold lines disposed on opposite sides of the chute; F. wherein the base, spout, closure, and tear line are injection molded as one integrally formed piece. ### Claim 20 A spout for a container, comprising: A. a base adapted to be joined to a wall of a container, the base defining an opening; B. a chute communicating with the opening, the chute having a first end at least partially surrounding the opening and a second end spaced from the first end; C. a closure positioned to close the chute; D. a tear line defining a seal of the closure, the tear line being adapted to be broken readily, without the tear line being broken in a sequential, rotational direction about the tear line about an axis perpendicular to the base, to open the spout; and E. a projection configured to puncture the tear line to break the tear line; F. wherein the base, spout, closure, projection, and tear line are injection molded as one integrally formed piece.
