Abstract
A top-fill hummingbird feeder has a liquid container with a lower bottom opening which can be screw-threaded into a central collar of a feeding basin. An insert is received within the central collar and is configured to be vertically movable between a first position in which fluid is allowed to flow from the liquid container to the basin, and a second position in which fluid flow from the container to the basin is prevented.
Claims20
A hummingbird feeder comprising:
- a liquid container having a top end opening and a bottom end opening;
- a removable cap for sealing the top end opening;
- a sealing mechanism operatively connected to the bottom end opening, said sealing mechanism including a movable component coupled to a lower end of said liquid container and linearly movable with said liquid container, and a seal element positioned below said movable component;
- a feeding basin having a base with an upwardly projecting connecting element configured to be movably coupled with said movable component, said connecting element having an outer wall with mouth openings therein adjacent said fluid basin base, said feeding basin further having at least one feeding port in liquid flow communication with a fluid holding area inside said basin;
- said sealing mechanism being activated by vertical movement of said liquid container and movable component so that, when said liquid container is pulled upwardly away from said basin, said movable component is moved to a first position with respect to said connecting element in which fluid flow from the liquid container into said fluid holding area through the mouth openings is enabled and, when said liquid container and movable component are pushed downwardly toward said basin, said movable component is moved to a second position relative to said connecting element in which said seal element blocks said mouth openings and prevents fluid flow from the liquid container into said fluid holding area.

A hummingbird feeder comprising:
- a liquid container having a top end opening and a threaded bottleneck forming a bottom end opening;
- a removable cap for sealing the top end opening;
- a movable sealing member having a threaded inner bore by which said sealing member is operatively connected to the threaded bottleneck so as to be movable with said liquid container, said movable sealing member also having at least a first engaging structure on an outer surface thereof;
- a feeding basin having a centrally located and upwardly extending mounting part for receiving said movable sealing member and at least one feeding port in liquid flow communication with a fluid holding area inside said basin;
- said mounting part including at least a second engaging structure operative to be flexibly engaged with said first engaging structure to define a first movable sealing member position in which fluid is able to flow from the liquid container into the fluid holding area, and a second movable sealing member position in which fluid flow from the liquid container into the fluid holding area is prevented, entry into said first and second positions being determined by vertical movement of said container and said movable sealing member toward and away from said feeding basin.
