Closure having improved tamper evident features
View Patent ↗A flip-top type tamper evident closure for dispensing material from a container includes a body portion having a dispensing opening, a lid portion hingedly connected to the body portion and a tamper evident band that is frangibly connected to the body portion. The tamper evident band is constructed and arranged to engage structure on the lid portion in an interlock arrangement in order to retain the lid portion in a closed position prior to the closure first being opened by a consumer. Advantageously, as an additional security measure the tamper evident band is further lightly spot-welded to the lid portion, which prevents or makes evident any attempt to overcome the interlock arrangement. A method of making the closure is also disclosed.
1. A closure for dispensing material from a container, comprising:
a body portion that is adapted to be mounted onto a container, said body portion having a dispensing opening defined therein;
a lid portion hingedly connected to said body portion so as to be movable between a first, closed position and a second, open position;
a tamper evident band frangibly connected to said body portion, said tamper evident band being shaped, sized and positioned to engage structure on said lid portion in order to preclude movement of said lid portion away from said first, closed position, said structure on said lid portion comprising a projection extending radially outwardly from said lid portion, said projection being shaped, sized and positioned to engage an underside of said tamper evident band; and
temporary securement means for temporarily securing said tamper evident band to said lid portion, whereby security of said closure prior to opening by a consumer is enhanced.
2. A closure for dispensing material from a container according to claim 1 , wherein said temporary securement means comprises at least one spot weld frangibly connecting said tamper evident band to said lid portion.
3. A closure for dispensing material from a container according to claim 2 , wherein said temporary securement means comprises a plurality of spot welds frangibly connecting said tamper evident band to said lid portion.
4. A closure for dispensing material from a container according to claim 3 , wherein said temporary securement means is further configured so that said spot welds are spaced substantially regularly along an area of interface between said tamper evident band and said lid portion.
