Abstract
A drip irrigation device for distributing a portion of the water flowing in an irrigation pipe to a plant, the device comprising: a housing formed from a relatively soft plastic; and a connector for coupling the housing to the irrigation pipe comprising a bayonet for puncturing the irrigation pipe formed from a relatively hard material over-molded onto a feature of the housing made from the soft plastic.
Claims19
A drip irrigation device for distributing a portion of the water flowing in an irrigation pipe to a plant, the device comprising:
- a housing formed from a relatively soft plastic;
- and
- a connector for coupling the housing to the irrigation pipe comprising a bayonet for puncturing the irrigation pipe formed from a relatively hard material over-molded onto a feature of the housing made from the soft plastic.
A press-fit pipe coupler for connecting at least one first pipe to a second pipe or apparatus, the coupler comprising:
- at least one tube formed from a relatively soft plastic;
- and
- at least one protrusion injection over-molded on each of the at least one tube from a relatively hard plastic for gripping an inside surface of the first pipe.
A method of producing a drip irrigation device for distributing a portion of the water flowing in an irrigation pipe to a plant, the method comprising:
- injection molding a housing from a relatively soft plastic;
- and
- injection molding a relatively hard material to form a bayonet for puncturing the irrigation pipe so that the bayonet couples to a feature of the housing.
A method of producing a press-fit pipe coupler for connecting at least one first pipe to a second pipe or apparatus, the method comprising:
- injection molding a relatively soft plastic to form at least one tube;
- and
- injection molding a relatively hard material to form at least one protrusion on each of the at least one tube for gripping an inside surface of the first pipe.
