DETAILED DESCRIPTION

[0083] The present invention provides a canister or bottle or container, hereinafter called canister, with an integral child-resistant cap for dispensing liquid and a button to force a prescribed amount of liquid each time the button is pushed. As described in the present invention, all components except the O-rings, the button and the spring are injection molded plastic. The container may also be made of metal, glass or any material suitable for contact with food, whereby all components are a permanent part of the sealed assembly and not intended for reuse.

[0084] FIG. 1 shows the unitized assembly of the invention consisting of a Canister (14), on top of which a Top Cap Assembly (10) is affixed and below which a Bottom Cap Assembly (16) is affixed.

[0085] As shown in FIG. 2a, the Top Cap Assembly (21) consists of a Nozzle (22), a Logo/Color Badge (23), a Seal Disk (24), and a single Small O-ring (29). The Logo/Color Badge (23) snaps into the Top Cap (21) and through the use of various colors is used to identify the canister's contents. Below the Logo/Color Badge (23), the Seal Disk (24) sits in a recessed cutout and is held in place by the Logo/Color Badge (23).

[0086] On the underside of the Top Cap (21), the Nozzle (22) is permanently snapped into place. A single Small O-ring (29) is inserted in the cutout on the bottom of the Nozzle (22) and used to provide a leak tight seal between the Top Cap Assembly (21) to the Canister (14).

[0087] As shown in FIG. 2b, the Bottom Cap Assembly (21) consists of a Bottom Cap (25), a Button (26), a Spring (27), and a Button Retainer (28) and two Large O-rings (30). The Button (26) and Spring (27) are placed in the Bottom Cap (25) as shown. The Button Retainer (28) is placed over the Button (26) and Spring (27), thereby compressing the Spring (27), and is snapped into the Bottom Cap (25). Two Large O-rings (30) seal the Bottom Cap (25) to the Canister (14) when the Bottom Cap (25) is snapped into the bottom of the Canister (14). The Spring (27) is used to assist the Button (26) in returning to its original shape, allowing it to be pressed again and squirt a known volume of liquid each time.

[0088] The Canister (14) is shown in FIG. 3. It is made of FDA approved injection molded plastic and shows in detail a hub on top of the Canister (14) where the connection is made to the Top Cap (21). The Side (31) of the cylindrical shaped Canister (14) is clear to allow placement of graphics and labels. The hub has a Small O-ring Grove (33) to seal the connection, and a Non-Spin Rib (35) to keep the Top Cap (21) aligned with the graphics and labels. The Hole (37) in the top of the hub allows liquid to flow from the Canister (14) to the Nozzle (22) located in the Top Cap (21).

[0089] The Top Cap (21) is shown in FIG. 4 in both a closed view and an open view. It is made of FDA approved injection molded plastic. Shown are the Living Hinge (41) and the push to release, adjustable Child-Resistant Latch (43). The Seal Cutout (45) is shown on the underside of the lid and receives the Seal Disk (24) and the Logo/Color Badge Cutout (47) is shown on the top side of the lid and receives the Logo/Color Badge (23).

[0090] FIG. 5 details the Bottom Cap (25) showing the two Large O-ring Groves (51) that seal the Bottom Cap (25) to the Canister (14), and the Locking Tabs (53) that lock the Bottom Cap (25) into the Canister (14) and prevent it from turning. It is made of FDA approved injection molded plastic. The Bottom Cap (25) snaps into the bottom of the Canister (14) and is not removable, The Button (26) slips into the center of the Bottom Cap (25).

[0091] The Button Retainer (28), FIG. 6, snaps into the Bottom Cap (25) and holds the Button (26) in place. It is made of FDA approved injection molded plastic. The Button (26) creates a seal between the retainer and the Bottom Cap (25) when both are snapped into the Canister (14), The Spring (27) is placed inside the Button (26) before the Bottom Cap Assembly (16) is snapped into the bottom cap and is not meant to be disassembled.

[0092] FIG. 7 shows the Button (26) made of FDA approved elastomeric material such as rubber.

[0093] When pressed, the Button (26) forces an amount of liquid through the tip. The Spring (27) helps the button to return to its original shape when released.

[0094] The Nozzle (22) is shown in FIG. 8. The Nozzle (22) is made of FDA approved injection molded plastic and is snapped into the Top Cap (21) and directs the liquid out of the Canister (14) and into the receiving device. The Nozzle (22) and Top Cap (21) assembly are not meant to be disassembled.

[0095] The Logo/Color Badge (23) is shown in FIG. 9. The Logo/Color Badge (23) is made of FDA approved injection molded plastic and snaps into the Top Cap (21) and may be used to identify the product, date, lot, expiration, manufacturer, contents, etc. The Logo/Color Badge (23) is used to hold the Seal Disk (24) in place. The Logo/Color Badge (23) is not meant to be disassembled.

[0096] FIG. 10a shows the Large O-rings (30) which are made of FDA approved elastomeric material such as rubber and are used to seal the Bottom Cap (25) to the Canister (14).

[0097] FIG. 10b shows the Small O-ring (29) which is made of FDA approved elastomeric material such as rubber and is used to seal the Top Cap (21) to the Canister (14).

[0098] FIG. 10c shows the Seal Disk (24) which is made of FDA approved elastomeric material such as rubber and is used to seal the Nozzle (22) and prevent spillage when the Top Cap (21) is closed.

[0099] FIG. 11 shows the Spring (27) which is made of FDA approved stainless steel and is used to return the Button (26) to its normal position after being pressed.
