The present invention relates generally to bird feeders. More particularly, the present invention relates to a bottle cap and a bottle for use as a hummingbird feeder.
Millions of people around the world enjoy watching and feeding wild birds. These people love to feed the wild birds in their backyards or on their balconies so that they can enjoy watching the birds. While there are many types of wild birds that people like to watch and feed, the hummingbird is a favorite for many people. Hummingbirds are attracted to sweet nectar produced by flowers. As a substitute for the sweet nectar, people use water sweetened by sugar in hummingbird feeders to attract and feed the hummingbirds.
A typical hummingbird feeder is comprised of a fluid reservoir for holding the sugar water which is conveyed to a plurality of simulated flowers. The hummingbirds insert their long thin beak into holes in the simulated flowers to drink the sugar water. While the sugar water is an effective substitute for natural flower nectar, the use of sweetened water has several drawbacks.
In warm climates, the sweetened water has a tendency to ferment which can quickly lead to the production of bacteria, mold and mildew. The bacteria, mold and mildew will discolor the sweetened water and may begin to grow inside the fluid reservoir. As a result, the hummingbird feeder can quickly turn into an unsightly mess. In addition, the bacteria, mold and mildew can also be harmful and fatal to the hummingbirds. As a result, hummingbird feeders must be cleaned on a regular basis, for example, every three or four days. The constant hassle of cleaning the hummingbird feeder has caused many people to stop using their hummingbird feeders.
Thus, there is a need for a new hummingbird feeder which overcomes the problems cited above.
It is therefore a feature and advantage of the present invention to provide a hummingbird feeder which requires minimal or no cleaning at all.
According to one aspect of the invention, a bottle cap is provided with at least one feeding port, wherein the bottle cap can be screwed onto a plastic bottle thereby turning most plastic bottles into a hummingbird feeder.
According to another aspect of the invention, a disposable plastic bottle with a cap with at least one feeding port is disclosed which is pre-filled with a nectar to create a hummingbird feeder.
In accordance with one embodiment of the present invention, a bottle cap for fitting on a mouth of a bottle is disclosed. The bottle cap comprises: a first chamber with a opening for receiving the mouth of the bottle, wherein the bottle cap snaps onto the mouth of the bottle; a second chamber with a closed bottom; a sealing ring located between the first and second chambers so as to provide a seal between the bottle cap and the mouth of the bottle when the bottle cap is snapped onto the mouth of the bottle, wherein liquid is free to move between the first and second chambers; and at least one feeding port in a side wall of the second chamber.
In accordance with one embodiment of the present invention, a bird feeder is disclosed. The bird feeder comprises: a fluid reservoir and a mouth; a cap which is attached to the mouth of the fluid reservoir, the cap comprising: a first chamber with a opening for receiving the mouth, wherein the cap snaps onto the mouth of the fluid reservoir; a second chamber with a closed bottom; a sealing ring located between the first and second chambers so as to provide a seal between the cap and the mouth when the cap is snapped onto the mouth, wherein liquid is free to move between the first and second chambers; and at least one feeding port in the wall of the second chamber.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described below and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein, as well as the abstract, are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
The invention will now be described, by way of example, with reference to the accompanying drawings, wherein:
a)-1(b) illustrate side views of a bottle cap according to two embodiments of the invention;
According to one embodiment of the invention, a bottle cap is provided with at least one feeding port, wherein the bottle cap can be snapped or screwed onto a plastic or glass bottle thereby turning most bottles into a hummingbird feeder. In this embodiment, when the feeder needs to be cleaned, the bottle is simply thrown away and a new bottle is used. Thus, only the bottle cap needs to be cleaned if not thrown away as well. According to another embodiment of the invention, a disposable plastic bottle with a cap with at least one feeding port is disclosed which is pre-filled with a nectar, such as water mixed with a pure white sugar solution to create a hummingbird feeder. In this embodiment, the entire feeder is disposable and is thrown away when the nectar is gone or the feeder needs to be cleaned. Thus, the hassle of cleaning the feeder is completely eliminated.
a) illustrates a side view of a bottle cap 10 according to one embodiment of the invention. The bottle cap 10 comprises an opening 11 and a side wall 13 with threads 14 so as to allow the bottle cap 10 to be screwed onto the mouth of a bottle (not illustrated). In the alternative, the cap 10 may snap onto a threadless mouth of a bottle by forcing the cap 10 onto the mouth of the bottle. To further facilitate the attachment of the cap to a treadles bottle, the cap 10 may have a snap on lip seal 90 for accommodating the protruding lip which is common on the mouth of threadless bottles. Furthermore, the side wall 13 of the cap 10 may be threadless as illustrated in
Returning to
According to one embodiment of the invention, the hollow stem 17 projects outward from the bottle cap 10 and is substantially parallel to the bottom 12 of the bottle cap 10 as is illustrated in
According to another embodiment of the invention, a perch 80 may be connected to the outside of the bottom of the bottle cap 10 as illustrated in
The bottle cap 10 and all of its components are preferably made of plastic or rubber but the invention is not limited thereto. The bottle cap 10 and all of its components may be a single piece of plastic, formed through, for example, an injection and/or blow molding process, or be formed of multiple pieces which are connected together and the invention is not limited thereto.
In use as part of a hummingbird feeder 30, the bottle cap 10 is attached to a bottle 31 which is filled with a nectar 35 as illustrated in
As mentioned above, the bottle cap 10 may comprise first and second fluid chambers 15, 16 which have different shapes. For example, as illustrated in
According to another embodiment of the invention, the feeder 30 with the bottle 31 and the bottle cap 10 can be sold to the user pre-filled with nectar. In this embodiment where the feeder 30 is completely disposable, the feeding ports 21 are sealed by a sealant film or plug 40 to prevent the feeder 30 from leaking prior to use. In use, the feeder 30 may have a hook or loop 33 to which a rope, string or a chain can be attached to allow the feeder 30 to be hung. Alternatively, the feeder 30 may be hung using some other hanging device. In this embodiment, when the feeder 30 needs to be cleaned, the entire feeder 30 is thrown away and a new feeder 30 is then used. Thus, the hassle of cleaning the feeder 30 is completely eliminated.
According to another embodiment of the invention, the bottle cap 110 may have a top section 120 which is shaped and sized like a plug as illustrated in
According to another embodiment of the invention, the top section 220 of the bottle cap 210 may be surrounded by a plug 230 made of rubber, cork, flexible plastic or some other flexible material as illustrated in
