Pull-out expandable contractible pour spout cartridge insert for liquid container openings

Abstract

An expandable contractible pour spout cap insert adapted to secure to openings of fluid containers for motor oils, transmission fluids, cooking oils, liquors, etc. with an extendable corrugated hose in communication with the interior of the container and an open pouring end, which extends in a pour position, and collapses back into the pour spout cap insert in a storage position.

Claims

1. A screw-on expandable contractible pour spout cap cartridge insert adapted to removably secure to a threaded pour opening of a fluid container, comprising: a. a pull cap with a top and a finger pull ring affixed to the top, and a threaded pull cap base, wherein the pull cap finger pull ring extends beyond the top of the pull cap when pulled, b. a flexible telescoping accordion pour spout defining an interior channel with first and second open ends having a collapsed condition in a storage mode and an extended condition in a pouring mode with the first open end threaded to removably secure to the threaded pull cap base, and the second open end mounted in communication with the threaded pour opening of the fluid container, the threaded pull cap base removably secured to the threaded first open end of the flexible telescoping accordion pour spout to close its channel in the storage mode, and removed from the threaded pull cap base for the flexible telescoping accordion pour spout to pour in the pouring mode; c. a flexible extension/eversion plastic diaphragm with a top affixed to the second open end of the flexible telescoping accordion pour spout and a bottom sized and structured, when secured, to seal about the threaded pour opening of the fluid container; said plastic diaphragm structured to extend beyond the threaded pour opening of the fluid container to release and allow extension of the flexible telescoping accordion pour spout for pouring in the pouring mode, and everted to store the flexible telescoping accordion pour spout in a collapsed condition within the threaded pour opening of the fluid container in a storage mode, and d. a pour spout threaded base structured as a threaded nut fitting with a base opening, which surrounds and secures the bottom of the extension/eversion plastic diaphragm to removably seal to the threaded pour opening of the fluid container to align the interior channel and second open end of the flexible telescoping accordion pour spout in communication with the fluid container pour opening of the fluid container; the pour spout threaded base having a notched top structured to accommodate the finger pull ring extension when collapsed against the pour spout threaded base.

2. The pour spout cap cartridge insert according to claim 1, wherein the bottom of the flexible extension/eversion plastic diaphragm is structured as a flanged gasket with a gasket opening sized to secure about and seal the gasket opening in communication with the pour opening of the fluid container.

3. The pour spout cap cartridge insert according to claim 1, wherein the pour spout threaded base has internal threads within its base opening structured to secure to corresponding external threads of the neck pour opening of the fluid container.

4. The pour spout cap cartridge insert according to claim 1, including a storage cap with sidewalls sized and structured to encase the telescoping accordion pour spout in collapsed condition within the extension/eversion plastic diaphragm with edges having structure to removably secure to the pour spout threaded base exterior.

5. The pour spout cap cartridge insert according to claim 4, wherein the storage cap with sidewalls includes structure which removably secures to corresponding structure on the pour spout threaded base exterior.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

(10) FIG. 1 illustrates a perspective view of the extended pour spout cap insert 8 affixed to the neck opening of a fluid container. The pour spout cap 10 has a pull ring 12. The pour spout cap 10 is attached to a threaded end 14 of a flexible extendable/collapsible accordion hose 16 to extend the same for pouring. The other end 18 of the flexible accordion hose 16 is affixed to the top 20 of a flexible extension/inversion plastic diaphragm 22 forming a continuous channel in communication with the interior of the container, when mounted to the neck opening of a fluid container by the pour spout cap base 26. The bottom 24 of the flexible extension/inversion plastic diaphragm 22 is flanged, and secured by the pour spout cap base 26 to the neck opening of the fluid container forming a gasket type fluid tight seal.

(11) The pour spout cap 10 is unscrewed from the threaded end 14 of the flexible accordion hose 16 for pouring fluids from the container. After pouring, the pour spout cap 10 is screwed back on to store remaining fluids in the container.

(12) FIG. 2 illustrates a perspective view of the pour spout cap insert 8 of FIG. 1 contracted to store within the neck opening of the container the compressed flexible accordion hose 16 supported by the inverted flexible extension/inversion plastic diaphragm 24, which is then secured within the neck opening of the fluid container by the pour spout cap base 26. A protective storage cap 28 shown in FIG. 3 with internal structure may be employed to secure the contracted assembly to the pour spout cap base 26. The pour spout cap base 26 has internal threads 30 adapted to secure to external threads 32 of the neck opening of a fluid container.

(13) FIG. 2a illustrates the embodiment of FIG. 2 extended for pouring.

(14) FIG. 3 illustrates the separate components of the pour spout cap insert 8 disassembled showing a storage screw cap 28 structured with a snap fitting base, which removably secures to the bottom 24 of the flexible extension/inversion plastic diaphragm 22. A removable tamper resistant seal 29 is located beneath the bottom of the storage screw cap 28.

(15) FIG. 4 illustrates a cross-sectional view of the pour spout cap insert 8 interior where its components define an internal channel when mounted in communication with the interior of a fluid container.

(16) FIG. 5 illustrates a perspective exterior view of the pour spout cap insert 8 of FIG. 4. An optional removable seal 34 is shown on top of the threaded end 14 of the flexible accordion hose 16 to prevent product tampering.

(17) FIG. 6 illustrates a top view of the pour spout cap 10 showing the pull ring tab 12.

(18) FIG. 7 illustrates a perspective bottom view of the pour spout cap 10 of FIG. 6. The pour spout cap 10 has internal threads 32, which removably secure to external threads 30 of a neck opening of a fluid container as shown in FIGS. 2 and 2a.

(19) FIG. 8 illustrates a top view of another variation of a pour spout cap 10 with finger pulls 12.

(20) The present invention may be embodied in other specific forms without departing from its structures, methods, or other essential characteristics as broadly described herein and claimed hereinafter. The described embodiments are to be considered in all respects only as illustrative, and not restrictive.

(21) The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
