Description

SPECIFICATION Bird feeder This invention relates to bird feeders. It is known to provide structures of varying degrees of elaboration for the purpose of feeding wild birds and in particular attracting them to the garden to feed, so that they can be observed.

The object of the present invention is to provide an improved bird feeder which is particularly cheap and economical.

According to the invention a disposable pack is intended for use once only and is at least part-filled with bird food, and forms the bird feeder itself without (or with only a minimum) of associated apparatus, said pack comprising a container containing the food, at least one access port for the beak of the bird, closure means preventing loss of food through the port in storage and transit, means for suspending or supporting the feeder in its place of use, and a perch located or locatable adjacent the port.

Preferably the pack also provides shelter for a bird on the perch.

Various embodiments of the invention will now be more particularly described with reference to the accompanying drawings wherein Figure 1 is a perspective view of a first embodiment; Figure 2 is a fragmentary front elevation of the same in a position different to that shown in Fig. 1; and Figures 3 and 4 are respectively sections taken on the lines 3-3 and 4-4 of Fig. 2; Figure 5 is a perspective view of a second form of the invention; Figure 6 is a front elevation of a third form of the invention and Figure 7 is a section taken on the line 7-7 of Fig. 6.

All of the embodiments herein described use containers which comprise a generally dish-shaped vacuum-formed transparent plastics sheet, commonly known as a "blister pack". Such blister pack is convenient for its transparency, in giving a ready indicatiion of the volume of contents remaining, as well as being cheap to manufacture and weather resistant. However, packaging materials other than blister packs may also be suitable as will be better understood after consideration of the following description.

Referring first to Fig. 1, the disposable bird feeder/bird food pack is shown herein in its position ready for use. It comprises a generally rectangular card or like backing 10 apertures at 12 so that it can be hung with a string from a tree branch, or nailed to a fence.

The blister pack forms a tray which is closed by the card, the pack having side walls 14, top and bottom walls 16, 1 8 and a front wall 20. The wall 20 is inclined at an angle to the card 10 and the wall 1 8 forms a shelter surface for a bird located below it.

The blister pack is formed with an integral projection 22 which is hollow and extends outwardly under the sheltering wall 1 8 with a generally central access port 24. The port can be covered by a strip of adhesive tape in transport and storage, or the port 24 can be punched in the projection when the bird feeder is to be brought into use but the punch location can be indicated for example by a printed line or an attached label prior to that.

It will be seen that when the feeder is hung from the hole 12, food in the blister pack will fall through the projection 22 so as to be accessible through the port 24, but because of the relatively small dimensions-typically the projection 22 has a vertical dimension at the card of about 2 cm, the food will tend to wedge at the base of the container provided by the blister pack so that when it is not being taken by birds it will not tend to spill out at the port 24. Fig. 4 shows the projection in section and the arrow 26 indicates the approximate position of the said port.

The perch is made as an extension of the blister pack and is initially (in storage and transit) located generally in the plane of the peripheral flange 30 of the blister pack which is adhered to the card 10. As best seen in Fig. 2, the flange 30 continues around the entire periphery of the food containing portion of the pack, and the perch comprises a pair of side members or stiles 32 connected by a pair of rungs 34, 36. In practice it is anticipated to be necessary to provide only a cut 38 (Fig.

2) separating the flange 30 from the adjacent portions of the stiles and rungs 32, 34, although this cut is exaggerated in width in Fig. 2 in the interest of clarity.

The stile 32 and the rung 36 are generally of channel section to increase the rigidity of the perch as best seen in Figs. 3 and 4. The rung 34 could be similarly reinforced.

The perch is intended to be folded from the position generally co-planar with the card 10 to a position at right angles thereto as shown in Fig. 1 so that it is below the shelter surface 1 8 and a bird perched on it has easy access to the port 24. To support the perch in that position, the card backing 10 is cut transversely at 38, on each side of the projectiion 22 and is creased along lines 40 extending from the cuts 38 generally lengthwise of the stiles 32, so that wing-like portions of the card 44 can be folded up at right angles with their top edges engaged in the channel section parts of the stiles 32. This also serves the purpose of preventing the cardboard returning to the position wholly co-planar with the portion 10, allowing the perch to fold back to the Fig. 4 position from the Fig. 1 position.

Turning now to Fig. 5, the disposable bird feeder/food package shown herein comprises a generally parallelogram container 50 having a flange projecting outwardly from its open mouth, and that flange is trapped between two layers of card 52, 54 which are stuck together, the portion 52 being unapertured so as to close the mouth of the container, and the portion 54 being apertured so that the part 50 projects therethrough. The layers are further apertured at 56 to provide a suspender eye and also below the container to provide a socket into which a short rod of tube 58 can be pushed to provide a perch. it will be noted that there is a greater width of card flange D2 below the container 50 than there is D1 above the container, so that a bird on the perch 58 can be partially located below the container and thus the container itself provides shelter for the bird.The container is apertured or is to be apertured generally in the position indicated by the broken line 60 as an access port for the bird to reach the food.

In storage and transit, the perch 58 can be located extending generally along the length of the flange D2, and could be for example held in place by tabs of card raised out of the front panel 54 for that purpose.

Turning now to the embodiment shown in Figs. 6 and 7, the feeder is to be suspended from the aperture 60 and the blister pack provides a main storage area for the food 72.

The blister pack provides a perch 74 which is sealed off from the food storage compartment 72 in the area indicated by the reference numeral 76. Between the perch and the food storage area, is an access port 78 which may be a plain hole, an area to be apertured (as explained with reference to Figs. 1 to 4) or may be formed as an integral internally projecting tube with a bevelled end as shown in Fig. 7, intending to be sealed and closed during storage and transit, for example by a patch of adhesive tape shown in broken line with the reference 82 Fig. 6. The inner end of the tube is bevelled as shown in Fig. 7 so that when the feeder is hanging from the eye 70, food falling downwardly in the container, as food is extracted by birds, will not fall through the access port, but will be available for the birds through that port.

The port 78 extends from a recessed area 84 so that a bird standing on the perch 74 will obtain some shelter from the overhanging food storage compartment 72. The vertical dimension of the recessed area 84 may be for example about 6 or 7 cms for this purpose, with the access port at the upper end of the recessed area.

Fig. 7 shows the blister pack with a peripheral flange 88 secured as by adhesive or heat sealing to the card or the like 10, but any convenient construction to provide a closed container can be utilised.
