Abstract
A tamper-evident dispensing closure system is provided for a container. The system has a body for extending from the container at the container opening. The body defines a dispensing orifice, a channel, and a retention member projecting over a portion of the channel. The system includes a lid for being moved between a closed position and an open position. An anchor member is provided for being received in the channel and has an engaging portion for engaging the retention member when the anchor member is received in the channel. At least one frangible web initially connects the anchor member with the lid so that the frangible web breaks when the lid is initially lifted from the closed position.
Claims13
A tamper-evident dispensing closure system for a container that has an opening to the container interior, said dispensing closure system comprising:
- a body capable of extending from said container at said opening as either a separate structure or as a unitaxy extension of said container, said body having
- (1) at least one dispensing orifice for communicating with said container opening,
- (2) a channel having a first sidewall and a second sidewall wherein said second sidewall is spaced from said first sidewall and said second sidewall is closer to said at least one dispensing orifice than is said first sidewall;
- and
- (3) a retention member in the form of a bead extending from said first sidewall toward said second sidewall over a portion of said channel;
- a lid hinged to said body for accommodating lifting of said lid relative to said at least one dispensing orifice between (1) a closed position over said at least one dispensing orifice, and (2) an open position away from said at least one dispensing orifice, said lid having a top wall and a skirt;
- an anchor member for being received in said channel and having an engaging portion in the form of a lip for engaging said retention member when said anchor member is received in said channel;
- and
- a plurality of spaced-apart frangible webs projecting outwardly from said skirt for initially connecting said anchor member with said lid for subsequently being broken when said lid is lifted from said closed position.
A tamper-evident dispensing closure system for a container that has an opening to the container interior, said dispensing closure system comprising:
- a body capable of extending from said container at said opening as either a separate structure or as a unitary extension of said container, said body having (1) at least one dispensing orifice for communicating with said container opening, (2) a channel which opens upwardly and extends in an arcuate configuration less than 360° around said at least one dispensing orifice, and (3) a retention member projecting over a portion of said channel;
- a lid for accommodating lifting of said lid relative to said at least one dispensing orifice between (1) a closed position over said at least one dispensing orifice, and (2) an open position away from said at least one dispensing orifice;
- an anchor member for being received in said channel and having an engaging portion for engaging said retention member when said anchor member is received in said channel;
- and
- at least one frangible web that initially connects said anchor member with said lid and that can be broken when said lid is lifted from said closed position.
A tamper-evident dispensing closure system for a container that has an opening to the container interior, said dispensing closure system comprising:
- a body capable of extending from said container at said opening as either a separate structure or as a unitary extension of said container, said body defining (1) at least one dispensing orifice for communicating with said container opening, (2) first and second channels, and (3) first and second retention members projecting over a portion of said first and second channels, respectively;
- a lid for accommodating lifting of said lid relative to said at least one dispensing orifice between (1) a closed position over said at least one dispensing orifice, and (2) an open position away from said at least one dispensing orifice;
- first and second anchor members for being received in said first and second channels, respectively, said first and second anchor members each having an engaging portion for engaging said first and second retention members, respectively, when said first and second anchor members are received in said first and second channels, respectively;
- and
- at least one frangible web that initially connects said anchor member with said lid and that can be broken when said lid is lifted from said closed position.
A tamper-evident dispensing closure system for a container that has an opening to the container interior, said dispensing closure system comprising:

- a lid for accommodating lifting of said lid relative to said at least one dispensing orifice between (1) a closed position over said at least one dispensing orifice, and (2) an open position away from said at least one dispensing orifice;
- an anchor member for being received in said channel and having an engaging portion for engaging said retention member when said anchor member is received in said channel;
- and
- at least one frangible web that initially connects said anchor member with said lid and that can be broken when said lid is lifted from said closed position;
- said channel having a first sidewall and a second sidewall;
- said second sidewall being spaced from said first sidewall and being closer to said at least one dispensing orifice than is said first sidewall;
- and
- said retention member having the form of a bead extending from said first sidewall toward said second sidewall.
