Abstract
The system disclosed herein is directed to a plunger adapted for use with a protective sleeve for shielding contaminants from the plunger. In one example, a plunger has a handle having a first end and a second end. A flexible cup is coupled to the first end of the handle. The flexible cup has an interior surface and an exterior surface. An inlet is disposed on the exterior surface of the flexible cup. A through-hole is located in the flexible cup offset from the inlet. A connector is coupled to the inlet between the flexible cup and the handle. The connector is configured to join the first end of the handle to the flexible cup.
Claims20
A plunger comprising:
- a handle having a first end and a second end;
- a flexible cup coupled to the first end of the handle, the flexible cup having an interior surface facing an opening of the flexible cup, and an exterior surface opposite the interior surface, the flexible cup having an inlet disposed on the exterior surface, the flexible cup contains a single through-hole located in the flexible cup offset from the inlet, wherein the single through-hole extends from the exterior surface to the interior surface, the single through-hole is configured to receive a body of a protective sleeve therethrough;
- and
- a connector coupled to the inlet between the flexible cup and the handle, the connector configured to join the first end of the handle to the flexible cup, the through-hole is open to atmosphere when the plunger is not in use.
A plunger comprising:
- a handle having a first end and a second end, and a hollow cavity extending from the first end towards the second end;
- a flexible cup coupled to the first end of the handle, the flexible cup having an interior surface and an exterior surface, the flexible cup having an inlet disposed on the exterior surface, and a through-hole located in an external surface of the handle or in a top portion of the handle, wherein the through-hole is configured to receive a body of a protective sleeve therethrough and fluidically communicates with the hollow cavity;
- a connector having a hollow section, the connector disposed within the inlet, the connector configured to couple the first end of the handle to the flexible cup, the hollow section configured to enable the protective sleeve to pass from the inlet into the hollow section and through the hollow cavity from first end of the handle toward the second end of the handle and out the through-hole.
A plunger comprising:
- a handle having a first end and a second end, and a hollow cavity extending from the first end towards the second end;
- and
- a flexible cup coupled to the first end of the handle, the flexible cup having an interior surface and an exterior surface;
- a valve disposed between the first end and the second end of the handle, the valve comprising a biasing member configured to misalign through-holes in the valve;
- a connector disposed between the first end of the handle and the flexible cup, the connector having a hollow section;
- an inlet disposed on the exterior surface of the flexible cup, the connector disposed within the inlet, the connector coupling the flexible cup to the first end of the handle, wherein the connector is disposed within the inlet, and the connector is configured to couple the first end of the handle to the flexible cup, wherein the hollow cavity communicates with the hollow section of the connector, and the hollow section is configured to enable a protective sleeve to pass through the first end of the handle toward the second end of the handle.
