First use flow-delay membrane for pourable containerized motor oils and other viscous fluids

Abstract

The present invention is a flexible disc-like membrane that is burstable on demand. The membrane is adapted to accommodate an accommodating container (approximately 32 fl. oz.) for automotive type motor oils and other viscous fluids. The membrane serves to contain a fluid content within a container at first use, while the container (with cap removed) is being positioned for pouring and until the consumer manually initiates the membrane to burst so as to release the contained fluid into an engine or other equipment. The present invention improves container content pour-ability by allowing the consumer to manually initiate the release of a fluid content to a free-flowing action at the proper time as to avoid fluid content spillage without the need for the use of a funnel or other pouring assistance.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of Invention

[0002] The present invention relates to common containers (approximately 1 U.S. quart—32 fl. oz.) for automotive type motor oils and other viscous fluids where a burstable membrane is adapted to accommodate an accommodating container to postpone the first use free-flowing action of a containerized fluid in a manner that avoids fluid content spillage when pouring the fluid content into an engine or other equipment.

[0003] 2. Description of Prior Art

[0004] The current use of high density polyethylene (plastic) rectangularly shaped containers (approximately 32 fl. oz.) for motor oil and like fluids with an offset or centrally located tubular spout and a circular spout opening has improved ease of pour-ability for consumer usage to some degree over former use of cylindrical composite fiber containers that had no spout or spout opening. The invention of (Doering, U.S. Pat. No. 4,877,142) discloses a polyethylene rectangular container (approximately 32 fl. oz.) for motor oil with an offset tubular spout, as does the design of (Kearse et al., U.S. Pat. No. D352,904) and the design of (Bridger et al., U.S. Pat. No. D337,946). The disclosure of (Frazer, U.S. Pat. No. D314,509) includes a substantially rectangular container with a centrally oriented tubular spout. These containers all have provided some improvement to containerized fluid pour-ability but there is still a need for further improvement, especially at first use when the container is at maximum fullness of content. The prior art rectangular containers mentioned and others still lend themselves to content spillage at the beginning of pouring action because when rotating a container (with the usual cap removed) from the normal position (spout opening upward) to the inverted position for pouring (spout opening downward) there is an uncontrolled outward surge of the container content before the opening end of the container spout can be placed fully within the oil fill or other fluid fill opening of an engine or other equipment. Some of the prior art containers are particularly designed with offset and/or angular spouts to allow pouring to begin by rotating a container from the normal position (spout opening upward) to the horizontal position for pouring (spout horizontal) to align the opening end of the container spout with the engine oil or other fluid fill opening, thereby allowing a slower emptying of the container content to reduce uncontrolled content surge and reduce content spillage. These containers remain vulnerable to first use content spillage at the beginning of pouring, partially because of the containers' fullness of content and partially because of obstructions encountered on the engine or other equipment (hoses, belts, brackets, etc.). Most engines have fluid fill intake openings that are less than accessible to positioning a container fully in a pouring position (inverted or horizontal) to begin pouring before content spillage can occur. In most cases only after a portion of the container contents have been emptied can the container be handled with relative ease, as when the contents of a container are only partially emptied at the first use application, i.e. the pouring action of a container content is stopped before emptying all of the content at the first use application, at some later time the pouring action is re-started with the unused content of the container for a second application with minimal chance of content spillage for the second application. Therefore it is still the first use of the individual container that is most likely to cause content spillage without the use of a funnel or other pouring assistance.

[0005] The invention of (Maguire, et al., U.S. Pat. No. 5,419,467) discloses a two-piece on/off pouring spout able to be coupled to some types of common containers for motor oil or like fluids. This prior art is relatively inexpensive and improves container content pour-ability by allowing the container to be inverted before the content flow is released, but this invention has to be continually coupled and un-coupled from one container to another, i.e. the average automotive engine oil change usually requires 3 to 5 separate (32 fl. oz.) oil containers. In addition, this invention as with funnels or other pouring assistance devices will retain an oily film which has to be continually cleaned of product oil or like fluid and further has to be continually cleaned of dust, and foreign particles that tend to settle an oily surfaces.

[0006] In the case of small engines such as lawn mowers or other equipment where the oil fill intake opening is smaller than the average 32 fl. oz. container spout opening and where such equipment requires only one or less than one 32 fl. oz. container of oil to fill the equipment, the present inventions' primary use (first use delay of fluid content free-flow) may be by-passed if desired. Puncturing (popping-open) the flow delay membrane (of an accommodating container) inwardly with thumb or forefinger after the container cap removal and before positioning the container for pouring will allow the container to be used in the conventional manner, using a funnel or some form of pouring assistance to guide the uncontrolled content surge when pouring the fluid content. Even when the primary use of the flow delay membrane is occasionally by-passed, the present invention serves a secondary function by replacing and serving as the usual seal for the container when the container is originally filled, sealed and capped. However most oil and related fluid container manufacturers now produce container sizes specifically for small engines such as a 20 fl. oz. container for lawn mowers and like equipment.

[0007] The intended consumer usage of the present invention is automotive and industrial by improving containerized oil and related fluid pour-ability, but other uses may apply. The present invention can be manufactured and applied inexpensively enough to be used once and then discarded with the accommodating container when emptied. Most motor oil and like fluid containers are emptied at first use, i.e. the average automotive engine crankcase capacity for oil fill is from 3 to 5 U.S. quarts (96 fl. oz. to 160 fl. oz.), thus in the case of a 4½ U.S. quart (144 fl. oz.) capacity engine oil fill, 4 individual 1 U.S. quart (32 fl. oz.) accommodating containers would be emptied at first use and a 5th 1 U.S. quart (32 fl. oz.) accommodating container is only partially emptied at the first use. In this case the consumer temporarily recaps the partially emptied 5th container until the next use. The 5th partially emptied container can later be un-capped and then completely emptied with far less chance of content spillage during a second use because of the previously removed quantity of oil at the first use of the 5th container even though the flow delay membrane of the 5th container was ruptured at the first use of the 5th container.

SUMMARY OF THE INVENTION

[0008] The present invention is a first use flow delay membrane to postpone the first use free-flowing action of a pourable viscous fluid (motor oil and other fluids) from an accommodating container (approximately 1 U.S. quart—32 fl. oz.), until such container can be properly positioned for pouring as to avoid fluid content spillage without the need for the use of a funnel or other pouring assistance device. The flow delay membrane serves as a temporary diaphragm by blocking the container content free-flow while the consumer inverts the container (positions the container spout opening end downward) and until the consumer can place the container spout opening end fully within the oil fill or other fluid fill intake opening of an engine or other equipment, allowing the consumer to initiate, on demand, the rupture of the membrane, thereby allowing the free-flow action of the fluid content to begin after the accommodating container is properly positioned for pouring.

[0009] The flow delay membrane is a flexible, circular, disc-like membrane that includes radial grooves and diametric grooves and further includes separation seams along the diametric grooves for the membrane to be ruptureable (burstable) on demand. The present invention is diametrically dimensioned to accommodate the variant spout opening diameters of random variable types of containers (usually but not limited to 32 fl. oz.). A fluid filled and cap sealed accommodating container having the flow delay membrane in place is opened (container cap removed), thereby exposing the top side of the flow delay membrane intact, the container is then properly positioned for pouring. The consumer can, at this point, manually compress (squeeze) the container to pressurize the fluid content within the accommodating container, which in turn pressurizes the inside (bottom side) of the flow delay membrane causing the membrane to yield (rupture) radially outward from the diametric center of the membrane along the separation seams, thus releasing the gravity free-flow of the previously restricted container fluid content directly into the fluid fill opening of an engine or other equipment, thereby avoiding undesired content spillage and eliminating the need for the use of a funnel or other pouring assistance device.

[0010] The present invention is sufficiently inexpensive to be used once and then disposed of along with the accommodating container when emptied; can replace the usual seal (leak seal) of the accommodating container; and further does not interfere with the usual capping (cap closure) material or process of the accommodating container. Accordingly several objects and advantages of the present invention are to provide:

[0011] (a) A flow delay membrane that is adapted to the usual spout opening end rim of a motor oil or other viscous fluid common container.

[0012] (b) A flow delay membrane that can replace some types of usual seals (plastic or composite fiber) that are sometimes placed snuggly within and flush to the inside top of the usual cap of the container, and a flow delay membrane that can replace other types of usual seals (plastic, composite fiber, or metallic foil) that are sometimes affixed to the container usual spout opening end rim (for sealing only) at the time of the container filling and capping process.

[0013] (c) A flow delay membrane that can be incorporated into a common container for motor oil or other viscous fluids at the time of the container filling without changing the usual filling, sealing and capping process that the fluid filling manufacture uses to originally fill, seal and cap the container.

[0014] (d) A flow delay membrane that serves to avoid content spillage when pouring a fluid content, and a flow delay membrane that eliminates the need for the use of a funneling (flow guiding) device or other supplementary pouring assistance when pouring a fluid content.

[0015] (e) A flow delay membrane that improves pour-ability of a contained viscous fluid from an accommodating container at first use by delaying the natural free-flowing action of the contained fluid until, (with the usual cap removed) the container can be rotatively inverted (spout opening end positioned downward) and until the container can be maneuvered to having the container spout opening end being placed fully within the fluid fill opening of an engine or other equipment.

[0016] (f) A flow delay membrane whereby the consumer can manually initiate the free-flowing action of the contained fluid from an accommodating container, at the consumer's readiness, directly into the fluid fill opening of an engine or other equipment.

[0017] (g) A flow delay membrane that can be manufactured and applied cheaply enough to be discarded along with the accommodating container once the container contents have been emptied.

[0018] (h) A flow delay membrane that allows the normal air flow into an accommodating container where the normal airflow helps to facilitate a container content free-flow normally from a common container, hence normal air flow being allowed into the accommodating container by way of the open flow delay membrane once the accommodating container has been positioned for pouring and the flow delay membrane has been ruptured, and a flow delay membrane that can be by-passed (if occasionally desired) by punching through the membrane with thumb or forefinger before positioning the accommodating container for pouring to enable the use of the accommodating container in the conventional manner by employing a supplementary pouring assistance device.

[0019] A further object and advantage of the present invention is to provide a flow delay membrane that becomes secured against the inside top of the usual cap of an accommodating container by the usual capping of the accommodating container when the fluid filling manufacturer factory seals (caps) the container, whereby the flow delay membrane cannot be accidentally or intentionally ruptured before the factory emplaced cap is removed by the consumer. These and other objects and advantages will become apparent from the detailed description and drawings, which follow.

DETAILED DESCRIPTION OF THE INVENTION

[0030] As illustrated and described by the drawings and other reference the present invention is a substantially flat disc-like diaphragmatic membrane 10. Membrane 10 is flexible and is adapted to accommodate an accommodating container 12. Container 12 having an approximate capacity of one U.S. quart (32 fl. oz.) for containing motor oil or other fluids. Membrane 10 is accommodated at the end of a threaded tubular spout 14 of container 12 (FIGS. 1 and 3). More specifically, membrane 10 is permeated to a circular rim 16 of spout 14 where rim 16 defines and surrounds a circular opening 18 which is the fill or discharge opening at spout 14 of container 12 (FIGS. 1 and 3). Container 12 is normally positioned for filling, transport and storage with opening 18 of spout 14 facing upward and where opening 18 is normally regarded as the top of the container. Container 12 is normally comprised of plastic (polyethylene) and is usually rectangular in shape. Membrane 10 is comprised of a synthetic latex rubber or rubber-like material that is compatible with common automotive fluids such as motor oil and related fluids and is compatible with container 12 (the accommodating container) to which membrane 10 is to be accommodated. An average size for a preferred embodiment of the present invention is approximately {fraction (15/16)} inches in diameter and approximately {fraction (3/64)} inches in thickness (major portion thickness), but not limited to these dimensions. The true diameter, thickness and relative shape of the present invention is dictated by the variable spout opening end sizes and spout opening end shapes of the many diverse types of containers (approximately 32 fl. oz.) to which the present invention is to be adapted.

[0031] Molded into and defining the topside of membrane 10 is a plurality of diametric grooves 20 (preferred embodiment) along a plurality of axes of membrane 10 where grooves 20 intersect each other at the diametric center of membrane 10. For illustration purposes, grooves 20 are shown along the X-axis and the Y-axis of the preferred embodiment of membrane 10 (FIGS. 5 and 6) with grooves 20 continuing the major portion diameter of membrane 10 (FIGS. 1, 3, 5, 6, 8A, 8B and 9). From the diametric center of membrane 10, grooves 20 are in a radiate form extending outwardly and are V-shaped in cross section in the preferred embodiment but not limited to this form or shape. The depth of grooves 20 is through the major portion thickness of membrane 10 forming a plurality of separation seams 22 along and relative to grooves 20, with seams 22 being the remaining portion thickness of membrane 10 along grooves 20. The preferred V-shape (in cross section) of grooves 20 serves to create a clean straight debris free separation along the longitudinal centers of grooves 20 at seams 22 when membrane 10 is ruptured (popped-open). Grooves 20 and seams 22 shown in (FIGS. 1, 2, 5, 6, 7, 8A, 8B and 9). Seams 22 shown intact (FIGS. 1, 2, 5, 6, 7, and 8A) and shown separated (FIGS. 4, 8B and 9). In combination with grooves 20 there is molded into membrane 10 a plurality of radial grooves 24 (U-shape in cross section) in communication with grooves 20 (FIGS. 1, 2, 5, 6, 8A, 8B and 9) which forms and defines a plurality of symmetrically radiate and substantially triangular pop-open flaps 26 (flaps 26 shown in all FIGS.). The preferred U-shape of grooves 24 serves to define and facilitate of plurality of bending bases 28, one base 28 at each flap 26 of membrane 10. Bases 28 at flaps 26 of membrane 10 where membrane 10 is shown ruptured (popped-open), shown in (FIGS. 8B and 9). Bases 28 at flaps 26 of membrane 10 where membrane 10 is shown intact, shown in (FIGS. 1 and 8A). Grooves 20 communicating with grooves 24, in addition to defining flaps 26, serve to form and define a circumference ring edge 30 including and encircling membrane 10 (ring edge 30 shown in all FIGS.). The depth of grooves 24 is shallow leaving the major portion thickness of membrane 10 at base 28 (FIGS. 8A and 8B) to insure that flaps 26 do not separate from ring edge 30 at base 28 when membrane 10 is ruptured, membrane 10 shown ruptured (FIGS. 8B and 9).

[0032] Membrane 10 is adapted to accommodate an accommodating container, (after the container has been normally filled with a fluid) by permeating ring edge 30 of membrane 10 flush to rim 16 at spout 14 of container 12 thereby sealing opening 18 of the container spout and allowing the normal capping (process and material) of container 12 (filling and capping not shown). Membrane 10 (FIGS. 1 and 3) is shown in the projected attaching position to container 12, the attached position of membrane 10 to container 12 is shown in (FIG. 4) with membrane 10 ruptured. A threaded usual cap 32 (FIG. 3), when threadedly mated to spout 14 there provides compression to the accommodated membrane (membrane 10) at a top-side 42 of membrane 10 (top-side 42 shown all FIGS.) further sealing container 12 and thereby preventing membrane 10 from being ruptured before cap 32 is removed by the consumer, (cap 32, not shown mated to spout 14). Membrane 10 can serve as and replace a thin wafer-like usual seal 34 (FIG. 3). Seal 34 in some applications is a plastic or composite fiber material that is placed snuggly inside cap 32 before container 12 is capped. In other applications seal 34 is a plastic, composite fiber, or metallic foil material that is affixed to rim 16 at spout 14 of container 12 before container 12 is capped. Both applications of seal 34 are for sealing only, (applications of seal 34 not shown).

[0033] Upon removing cap 32 from the accommodating container, membrane 10 serves to delay the gravity free-flow of the container fluid content (content not shown) while the accommodating container is being inverted and maneuvered to having the opening end (opening 18) of spout 14 fully within a fluid fill usual opening 36 of an engine or other equipment, which is the proper pouring position for the pouring action of the container fluid content to begin conveniently (FIG. 4 opening 36 in phantom outline). Once the container is maneuvered fully into a proper pouring position, the consumer can then manually initiate membrane 10 to rupture thereby releasing the free-flow of the container content (FIG. 4 shows membrane 10 as ruptured, free-flow of container content not shown). Content spillage from a common container (without membrane 10) occurs mostly at first use when the container is at peak fullness and while the container is being maneuvered and is usually encountering obstacles on the engine or other equipment, i.e. hoses, belts, brackets etc. (content spillage and obstacles not shown).

[0034] The present invention prevents the gravity free-flow of the container fluid content while container 12 is being inverted and maneuvered fully into a proper pouring position until, at the consumers' readiness, container 12 is manually compressed (squeezed) by a consumer hand 38 (FIG. 4) to initiate the rupture of membrane 10 thereby allowing the container fluid content free-flow to begin (container content free-flow not shown). Manually compressing (squeezing) container 12 pressurizes the container fluid content (content not shown) thereby transferring pressure to a bottom-side 46 of membrane 10 (bottom-side 46 shown all FIGS.) causing the membrane to rupture at and along seams 22, whereby flaps 26 of membrane 10 pop-open radially outward from the diametric center of membrane 10, membrane 10 shown popped-open (FIGS. 4, 8B and 9). The outward pop-open action of flaps 26 causes grooves 24 to close, in cross section (FIG. 8B), and in turn assists in the radial bending action of flaps 26 at bases 28 further allowing the outward swing travel of flaps 26 within membrane 10 when the membrane is ruptured (FIG. 8B). Once container 12 is properly positioned for pouring and membrane 10 is ruptured (popped-open), membrane 10 then releases the fluid content of container 12 to a gravity free-flowing action (content free-flow not shown) for complete or partial emptying of container 12 at the first use of the accommodating container. In the case of partial emptying of the accommodating container at the first use, container 12 can be inversely positioned from the pouring position (the spout opening end downward) back to the normal position (the spout opening end upward) to end the first use before complete emptying of container 12 with far less chance of content spillage because of reduced content at the end of the first use, and container 12 can be later re-used at a second or further use with less chance of content spillage at the second use because of reduced content within container 12 at the start of the second use even though membrane 10 was previously ruptured at the start of the first use of container 12 (emptying of container 12 not shown).

[0035] Membrane 10 of the accommodating container can be manually by-passed, (after the usual cap removal of the accommodating container) where the consumer manually and inwardly punches-open membrane 10 of container 12, using thumb, forefinger or other object to enable the use of the accommodating container conventionally without membrane 10 intact at the first use of container 12, if occasionally desired, (punching-open membrane 10 of container 12 not shown). Membrane 10 cannot be prematurely ruptured through inadvertently or intentionally compressing the accommodating container (manually or otherwise) as long as the factory emplaced cap 32 remains threadedly mated to spout 14 of container 12, since an inside top area 40 (FIG. 3) of cap 32 normally compresses against a top-side 42 (FIG. 3) of membrane 10 when cap 32 is threadedly mated to spout 14 of the accommodating container thereby preventing the untimely rupture of membrane 10 (cap 32 not shown mated to spout 14 of the accommodating container).

[0036] The normal airflow into the spout opening of any of the common containers mentioned and others assist in allowing the outward natural free-flow of the fluid content from a common container when the container usual cap is removed and the container is inverted (inward air flow and outward content free-flow not shown). When container 12 with membrane 10 in place and intact is inverted; properly positioned for pouring; and membrane 10 is manually initiated to rupture, membrane 10 then allows the normal air flow into container 12 through a plurality of vertexial areas 44 formed by flaps 26 of membrane 10 when ruptured (FIGS. 4, 8B and 9) to assist in the outward natural free-flow action of the accommodating container fluid content when pouring (air flow and fluid content free-flow not shown).

[0037] Now having described a preferred embodiment of the present invention this description should not be construed as limiting the scope of the invention but as illustrations of the preferred embodiment, for example, the V-shaped grooves and the U-shaped grooves (in cross section) of the flow delay membrane may be of different shapes or depths; the flow delay membrane may be composed of other material; the pop-open flaps of the flow delay membrane may be of other or uncommon shapes without departing from the intended purpose and scope of the present invention. Therefore the spirit and scope of the invention should be limited only by the appended claims and their legal limitations rather than by the illustrations and descriptions given.
