Abstract
Disclosed is a filter attachment that removably couples with a faucet or other vessel. The attachment includes a flexible cover holding the filter on the vessel and that acts as a pressure relief mechanism if the water pressure of the faucet is above a predetermined threshold. Another flexible cover may be located on the opposite side of the attachment to allow reversible use and cleaning by backwashing. The attachment may further include a removable cap on one side that includes a flexible cover and that couples to the remainder of the attachment in a removable manner so as to allow other fitments to couple to the attachment.
Claims14
A filter attachment having a first end and a second end opposite the first end, the filter attachment comprising:
- a filter that filters liquid and that includes a first flexible cover at the first end, the first flexible cover forming a first aperture extending through the first flexible cover, the first flexible cover having a lower modulus of elasticity as compared to the filter;
- a cap removably coupled to the filter and having a second flexible cover at the second end, the second flexible cover forming a second aperture extending through the second flexible cover, the second flexible cover having a lower modulus of elasticity as compared to the filter;
- and
- a coupling that is one of integral with or coupled to the filter opposite the first flexible cover, the coupling providing a mechanism for coupling the filter to the cap.
A filter attachment having a first attachment end and a second attachment end opposite the first attachment end, the filter attachment comprising:
- a filter that filters liquid and that includes a first flexible cover at a first filter end, the first flexible cover forming a first aperture extending through the first flexible cover, the first flexible cover having a lower modulus of elasticity as compared to the filter;
- a coupling that is one of integral with or coupled to the filter at a second filter end opposite the first filter end;
- and
- a cap removably coupled to the filter and having a second flexible cover at the second end, the second flexible cover forming a second aperture extending through the second flexible cover, the second flexible cover having a lower modulus of elasticity as compared to the filter,
- wherein the first aperture communicates with the second aperture through the filter.
