Abstract
Insect blocking devices having floats and flappers to prevent insect access to standing water in traps. A device for insertion into a trap having a float that seals the trap from insects, when in-flow water is not present, and opens as a result of in-flow water, to permit in-flow water to pass and enter the trap.
Claims15
A device for retrofitting a pipe to block insect access to standing water in the pipe, the device comprising:
- a. a stopper capable of moving from a first position to a second position;
- b. a sealing member, wherein the stopper engages the sealing member in the first position and thereby forms an insect blocking seal;
- c. the stopper capable of moving to the second position by the action of in-flow water, wherein the movement of the stopper opens a channel for the flow of the in-flow water past the stopper and the sealing member;
- and
- d. wherein the stopper is capable of returning to the first position up the sensation of the in-flow water.
2 more elements
A method of blocking insect access to standing water in a trap, the method comprising:
- providing a float device in engagement with a sealing member in a pipe above standing water in a trap in the pipe, and between the trap and an opening of a pipe in fluid communication with the trap, the float device engaging with the sealing member and thereby preventing insects from traveling past the sealing member, wherein the insects cannot reach standing water in the trap;
- upon the in-flow of water into the opening the float floats way from the sealing member, whereby a flow passage is opened;
- flowing the in-flow water through the pipe into the trap and out of the trap;
- wherein when the in-flow water subsides the trap remains filled with standing water, sealing the trap, and wherein the float re-engages with the sealing member, thereby blocking insect access to the standing water in the trap.
1 more element
A device for blocking insect access to standing water in a trap, the device comprising:
- a. a grating;
- b. a first annular member;
- c. a housing;
- the housing having an upper end and a lower end and comprising a first post, a second post, a first window, and a second window;
- d. the first annular member connecting the grating to the upper end of the housing, whereby the grating is in fluid communication with the housing;
- e. the housing having an upper and a lower external selling ring, the sealing rings positioned adjacent an outer surface of the housing, and capable of engaging the inner surface of a pipe;
- f. a stopper located in the housing, and movable from a first position within the housing to a second position within the housing;
- and,
- g. a sealing member located within the housing and positioned near the lower end of the housing, wherein the stopper engages the sealing member in the first position and thereby forms an insect blocking seal.
