Claims16
A cartridge for being received and retained in a hollow closure housing suitable for engagement with a container around an opening to the container interior, said cartridge comprising:
- a body defining a dispensing passage for communicating with the container exterior and interior when said cartridge is received in said housing on said container;
- a valve seated in said body for shifting between a closed configuration occluding said passage and an open configuration accommodating the dispensing of the container contents through said passage;
- and
- a retainer engaged with said body to hold said retainer and body in a clamping relationship retaining said valve in said body, said retainer and body cooperating to maintain said engagement independently of said housing.
A closure for an opening to a container interior, said closure comprising:
- a body for being positioned on said container at said opening, said body defining a dispensing passage for communicating between the container exterior and interior;
- a valve seated in said body for shifting between a closed configuration occluding said passage and an open configuration accommodating the dispensing of the container contents through said passage;
- and
- a hinge and retainer extending from said hinge molded unitary with said body to permit said retainer to be swung by said hinge into engagement with said body, said retainer being engaged with said body at least one location separate from said hinge to hold said retainer and body in a clamping relationship retaining said valve in said body.
A closure for an opening to a container interior, said closure comprising:
- a hollow housing for engaging said container around said opening and defining an interior receiving structure;
- and
- a cartridge which is separate from, and disposed, in said housing receiving structure, said cartridge including
- (a) a body defining a dispensing passage for communicating with the container exterior and interior when said cartridge is received in said housing on said container;
- (b) a valve seated in said body for shifting between a closed configuration occluding said passage and an open configuration accommodating the dispensing of the container contents through said passage;
- and
- (c) a retainer engaged with said body to hold said retainer and body in a clamping relationship retaining said valve in said body, said retainer and body cooperating to maintain said engagement independently of said housing.
A cartridge for being received and retained in a hollow closure housing suitable for engagement with a container around an opening to the container interior, said cartridge comprising:
- a body defining a dispensing passage for communicating with the container exterior and interior when said cartridge is received inside said housing on said container;
- a valve seated in said body for shifting between a closed configuration occluding said passage and an open configuration accommodating the dispensing of the container contents through said passage;
- and
- a retainer engaged with said body inside said body to hold said retainer and body in a clamping relationship retaining said valve in said body, said retainer and body cooperating to maintain said engagement independently of said housing.
A cartridge for being received and retained in a hollow closure housing suitable for engagement with a container around an opening to the container interior, said cartridge comprising:
- a body defining a dispensing passage for communicating with the container exterior and interior when said cartridge is received in said housing on said container, said body adapted to be mounted to the inside of said housing from the bottom of said housing;
- a valve seated in said body for shifting between a closed configuration occluding said passage and an open configuration accommodating the dispensing of the container contents through said passage;
- and
- a retainer engaged with said body to hold said retainer and body in a clamping relationship retaining said valve in said body, said retainer and body cooperating to maintain said engagement independently of said housing.
A closure for an opening to a container interior, said closure comprising:
- a hollow housing for engaging said container around said opening and defining an interior receiving structure;
- and
- a cartridge which is separate from, and disposed inside, said housing interior receiving structure, said cartridge including
- (a) a body defining a dispensing passage for communicating with the container exterior and interior when said cartridge is received in said housing on said container;
- (b) a valve seated in said body for shifting between a closed configuration occluding said passage and an open configuration accommodating the dispensing of the container contents through said passage;
- and
- (c) a retainer engaged with said body inside said body to hold said retainer and body in a clamping relationship retaining said valve in said body, said retainer and body cooperating to maintain said engagement independently of said housing.
A closure for an opening to a container interior, said closure comprising:
- a hollow housing for engaging said container around said opening and defining an interior receiving structure;
- and
- a cartridge which is separate from, and disposed in, said housing interior receiving structure, said cartridge including
- (a) a body defining a dispensing passage for communicating with the container exterior and interior when said cartridge is received in said housing on said container, said body adapted to be mounted to the inside of said housing interior receiving structure from the bottom of said housing;
- (b) a valve seated in said body for shifting between a closed configuration occluding said passage and an open configuration accommodating the dispensing of the container contents through said passage;
- and
- (c) a retainer engaged with said body to hold said retainer and body in a clamping relationship retaining said valve in said body, said retainer and body cooperating to maintain said engagement independently of said housing.
