Abstract

A dispensing closure ( 40 ) includes a body ( 54 ) for being located at the opening of a container ( 44 ) defining a central axis ( 30 ) and having a pour spout ( 72 ). The body ( 54 ) including a crushable seal ( 200 ) surrounding the pour spout ( 72 ), and the body ( 54 ) including a lateral projection ( 210 ) extending therefrom. The closure ( 40 ) includes a closing element ( 56 ) for being removably attached to the body ( 54 ) and having a lateral projection ( 220 ) extending therefrom. The closing element ( 56 ) and the body ( 54 ) have a closed condition in which the crushable seal ( 200 ) seals between the closing element ( 56 ) and the body ( 54 ) and the lateral projections ( 210, 220 ) are confronting to inhibit separation of the closing element ( 56 ) away from the body ( 54 ) along the central axis ( 30 ).

First claim

What is claimed is:

1. A closure for use with a container, the container having an opening between an exterior of the container and an interior of the container where a fluent substance may be stored, said closure comprising:
A. a body for being located at the opening of the container, said body defining a central axis and having a pour spout defining an interior surface, said interior surface defining at least a portion of a passage for communicating with the container interior to permit the flow of a fluent substance through said body, said body including a flexible, crushable seal located laterally outwardly of said pour spout, said body including at least one body lateral projection extending laterally from said body;
B. a closing element for being removably attached to said body, said closing element defining
i. an outer wall for being mounted around at least a portion of said pour spout of said body,
ii. a cover that extends laterally inwardly from said outer wall, and
iii. at least one closing element lateral projection extending laterally from said closing element; and
wherein said closing element and said body have a closed condition, wherein in said closed condition (i) said flexible, crushable seal seals between said closing element and said body and (ii) said at least one body lateral projection confronts said at least one closing element lateral projection to inhibit separation of said closing element away from said body along said central axis.

2. The closure in accordance with claim 1 wherein said closure further comprises a metallic liner for being sealed between said body and a container.

3. The closure in accordance with claim 2 wherein said body includes at least one liner retention projection extending laterally outwardly therefrom for retaining said metallic liner with said body prior to said metallic liner being sealed between said body and said container.

4. The dispensing closure in accordance with claim 2 in which a portion of said body is formed from a plastic material and said flexible seal is formed from an elastomeric material that is relatively more resilient and flexible than said plastic material.

5. The closure in accordance with claim 1 wherein said flexible, crushable seal is integrally molded with said body.

6. The closure in accordance with claim 1 wherein said flexible, crushable seal has a frustoconical shape.

7. The closure in accordance with claim 1 wherein said closing element includes an outer flange having an annular sealing surface for sealing against said flexible, crushable seal of said body in said closed condition.

8. The closure in accordance with claim 1 wherein said body includes a top deck from which said flexible, crushable seal extends, said body including a recessed well located between said pour spout and said top deck.

9. The closure in accordance with claim 8 wherein said recessed well includes a drain aperture.

10. The dispensing closure in accordance with claim 1 in combination with a container of a fluent substance having a viscosity between about 40 mPa·s and about 600 mPa·s, said dispensing closure, said container, and said substance together defining a package.

11. The closure in accordance with claim 1 wherein said closure further comprises a ring-shaped metallic liner located axially inwardly of said flexible, crushable seal relative to said central axis.

12. The closure in accordance with claim 1 wherein said flexible, crushable seal has an arcuate shape, extending from a top deck of said body, defining a radially inwardly facing convex surface and a radially outwardly facing concave surface.

13. The closure in accordance with claim 1 wherein closing element includes an annular projection for surrounding said flexible, crushable seal when said closing element is in said closed position.

14. The closure in accordance with claim 1 wherein said flexible, crushable seal has an arcuate shape, extending from a top deck of said body, defining a radially inwardly facing concave surface and a radially outwardly facing convex surface.

15. The closure in accordance with claim 1 wherein body includes an annular rim surrounding said flexible, crushable seal and extending axially outwardly of a sealing surface of said closing element in said closed position.

16. The closure in accordance with claim 1 wherein said at closing element lateral projection includes a circumferentially-extending portion having an open first end and a closed second end including an axially-extending stop portion.

17. The closure in accordance with claim 16 wherein said closing element includes at least one ramp proximate to said open first end of said circumferentially-extending portion for limiting rotation of said closing element relative to said body in said closed condition.
