Tamper-evident, initially unitary, fitment and closure

An initially unitary fitment and closure combination, said fitment having a spout having an interior and an exterior and attachment means for attaching said fitment to an apertured container, said closure having a top and cylindrical skirt having an interior and an exterior depending from said top dimensioned to fit within said spout, cooperating seal means on said spout and said skirt to seal said spout and skirt to each other in assembled condition and frangible means joining said skirt to the upper end of said spout, a first tamper-evidencing means on said attachment means and second tamper-evidencing means on said closure engageable with said first tamper-evidencing means, said first and second tamper-evidencing means having first and second inter-engaging means, respectively, which interengage so that said fitment and said closure cannot be separated after assembly without rupturing one of said tamper-evidencing means to provide visual evidence of tampering, said attachment means comprising an annular attachment flange around said spoilt, said attachment means having an upper surface, said first inter-engaging means comprising at least two upstanding walls on said upper surface of said attachment means and a first lip on one of said walls, and said second inter-engaging means comprising a depending leg having a lower end outside said skirt depending from said top and a second lip on said lower end of said leg, said leg being positioned and dimensioned to fit between said walls, said lips inter-engaging.

In combination, a fitment and a closure,

• said fitment comprising a spout, a peripheral attachment means extending outward from vicinal a lower end of said spout, said attachment means comprising an annular flange for attaching said fitment to a container surrounding an aperture in said container,
• said closure having a top, a cylindrical skirt having an exterior wall depending from said top dimensioned to fit within said spout,
• cooperating seal means on said spout and said skirt to seal said fitment to said closure in assembled condition,
• first tamper-evidencing means on said attachment means, second tamper evidencing means on said closure, at least one of said tamper-evidencing means being frangible, said first and second tamper-evidencing means being inter-engaged in the assembled condition of said fitment and said closure with said skirt seated within said spout to restrain removal of said closure from said spout so long as both said tamper-evidencing means are intact.

An intermediate product comprising an initially unitary fitment and closure combination,

• said fitment having a spout having a spout interior and a spout exterior and peripheral attachment means extending outward from said spout exterior vicinal a lower end of said spout, said attachment means comprising an annular flange for attaching said fitment to a container surrounding an aperture in said container,
• said closure having a top, a cylindrical skirt depending from said top having a skin exterior dimensioned to fit within said spout,
• a first seal portion on said skin exterior, a second seal portion on said spout interior, said second seal portion being smaller in circumference than said first seal portion,
• said first and second seal portions comprising seal means to seal said skirt to said spout when said skirt has been inserted inside said spout,
• said first seal portion comprising an elongated cylindrical surface.
