The present invention relates to portable storage containers with separate compartments, and more particularly, to portable food storage containers for storing, separating, and mixing food items.
Breakfast cereal is typically prepared by placing cereal into a bowl and adding milk. A young child who prepares breakfast cereal at home or school may inadvertently spill the milk and/or cereal, which requires cleanup time and may ruin the child's breakfast. Additionally, adults who are in a rush to get to work may spill milk or cereal when preparing it for themselves or their children. Similarly, an adult who prepares and packs a lunch for his or her child may desire that his or her child eat a nutritious salad, and may wish to provide a dressing with the salad, such as an oil/vinegar mixture. Salad dressing, which is typically stored in a separate container, can similarly create spillage issues when dispensed by a child.
Cereal-milk and salad-dressing mixtures cannot be prepared too far in advance without sacrificing quality. For example, if milk is added to cereal the night before and left in the refrigerator, the cereal becomes soggy and undesirable. Similarly, if dressing is added to a salad too far in advance, the salad also becomes soggy and undesirable.
It would be advantageous if the preparations for and the creation of cereal-milk, salad-dressing, and other food mixtures could be set up in advance in a refrigerated portable container which separates these food items. It would also be advantageous if such a portable container were easily accessible, transportable, and operable by a child to create the food mixture from the components thereof at an appropriate time while preventing spillage.
This summary is not intended to identify or point to essential features or limit the scope of the subject matter claimed herein. The present invention relates to a portable storage container and method which utilizes a rotatable lid and a sealing/release mechanism to fluidly isolate and selectively fluidly couple food items stored within the container, with at least the following objectives:
To store food items associated with a food mixture in a single container with separate compartments, and enable easy mixing thereof without spillage;
To provide a sealing mechanism which fluidly isolates an internal insulated compartment storing a perishable food item from a second compartment storing an additional food item, and to facilitate mixing of the food items within a container without accessing an interior region of the container;
To enable a young child to operate a portable food storage container by gripping a top portion of the container and rotating the top portion to operate a sealing/dispensing mechanism that fluidly couples two food items within the container to facilitate mixing thereof;
To enable an adult to set up food mixture preparations in advance in a portable container configured to fluidly isolate the food items associated with the food mixture, and to fluidly couple the food items upon a particular operation to an exterior portion of the portable container without removing or ripping any portion of the container; and
To provide an internal reservoir within the container for storing one of the perishable food items, and a sealing and release mechanism operatively associated with the reservoir, to allow for storage of larger quantities of the perishable food item, and faster release of the contents thereof during operation of the container;
In accordance with one embodiment of the invention, a container comprises a top portion defining a first hollow region configured to store a first product, a bottom portion rotatably coupled to the top portion and defining a second hollow region configured to store a second product, and a sealing and release mechanism configured to fluidly isolate the first and second hollow regions when the top and bottom portions are at rest relative to one another, and to selectively fluidly couple the first and second hollow regions during relative rotation of the top and bottom portions.
In certain embodiments, the sealing and release mechanism is movable between a closed position in which the first hollow region of the top portion is fluidly isolated from the second hollow region of the bottom portion, and an open position in which the first hollow region is fluidly coupled with the second hollow region. Relative rotation of the top and bottom portions causes the sealing and release mechanism to move from the closed position to the open position. The sealing and release mechanism is preferably biased toward the closed position.
In accordance with other embodiments, a method is provided for combining first and second products within a portable container having a top portion and a bottom portion. The method includes pouring a first product into a first hollow region of the top portion via an inlet, adding a second product into a second hollow region defined by the bottom portion, detachably coupling the top and bottom portions with the top and bottom portions completely covering the first and second hollow regions and the first and second hollow regions fluidly isolated from one another, and rotating the top portion relative to the bottom portion to fluidly couple the first and second hollow regions with the top and bottom portions completely covering the first and second hollow regions.
Various other objects, advantages, features, and characteristics of the present invention, as well as the methods of operation and functions of related structural elements, and the combination of parts and economies of development and manufacture, will become readily apparent to those of ordinary skill in the art upon consideration of the detailed description below with reference to the accompanying drawings, all of which form a part of this specification.
A further understanding of the present invention can be obtained by reference to preferred embodiments set forth in the illustrations of the accompanying drawings. The drawings are not intended to limit the scope of this invention, which is set forth with particularity in the claims as appended or as subsequently amended, but merely to clarify and exemplify the invention. Accordingly, a more complete appreciation of the present invention and many of the attendant aspects thereof may be readily obtained as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings, where:
The present disclosure is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents which operate in a similar manner. Specific embodiments that may be practiced are shown by way of illustration and explanation. The embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments, and it is to be understood that logical, mechanical, and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense. In describing exemplary embodiments of the present invention illustrated in the drawings, specific terminology is employed for sake of clarity.
The portable container of the present invention can be used to set up the ingredients of food mixtures, such as milk-cereal or salad-dressing mixtures, in advance. The container fluidly isolates the food component ingredients in separate compartments, and may be locked and transported in this configuration. During a mixing operation, the top portion of the container is rapidly rotated relative to the bottom portion of the container to actuate a sealing and release mechanism. Once actuated, the sealing and release mechanism uncovers an aperture in a compartment or reservoir in the top portion of the container to release one of the food components stored therein into the other food component stored in the bottom portion of the container. As the food components mix, the top and bottom portions of the container fully encapsulate the food mixture, and prevent spillage thereof. The release mechanism is biased toward a sealing configuration, and returns to this sealing configuration upon cessation of rapid relative rotation of the top and bottom portions. The container is reusable, washable, accessible, transportable, and operable by a child or adult to create desired food mixtures from food components at appropriate times while preventing spillage.

Top portion 12 is preferably bowl shaped, semi-spherical, and sized to completely cover hollow region 18 of bottom portion 16 when placed on and attached to bottom portion 16. Top portion 12 thus functions as a lid during storage and/or mixing of food items within container 10. In certain embodiments, top portion 12 may have a convex outer surface 13 extending to a circumferential edge 17, and a rubber seal 22 applied to circumferential edge 17. Top portion 12 also includes a threaded inlet 24 at an apex 26 thereof for receiving a first food item (e.g., milk 15). Inlet 24 defines an opening 28 in fluid communication with internal compartment 14, whereby milk 15 poured into inlet 24 via opening 28 flows into internal compartment 14. A removable cap 30 is preferably provided which detachably couples to inlet 24. When removable cap 30 is detached from inlet 24, opening 28 is uncovered or exposed.
Removable cap 30 may be provided with female threads 32 which engage with male threads 34 on inlet 24 to threadably engage and tightly fit removable cap 30 to inlet 24 as shown in
Internal compartment 14 is preferably lined with rubber and/or other insulators to help maintain the temperature of a food item placed therein and to delay spoilage of the food item. Internal compartment 14 may be constructed as a small internal section of top portion 12 with sidewalls defining a compartment in communication with inlet 24, or may simply be a hollowed region of substantially the entire internal region of top portion 12. By way of example, as shown in
Continuing with reference to
Below circular plate 38, circumferential wall 42 defines female threads 50 configured to receive male threads 52 (
Bottom portion 16 of container 10 is also preferably bowl shaped, semi-spherical, and sized to hold one or more servings of cereal. Bottom portion also preferably has a convex outer surface 54 extending to a circumferential edge 55, and a rubber seal 56 applied to thereto. It will be appreciated that when top portion 12 is fully screwed onto bottom portion 16, rubber seal 56 of bottom portion 16 will contact rubber seal 22 of top portion 12. Rubber seals 22, 56 may compress one another in the assembled configuration of

The forced acceleration of top portion 12 combined with the degree of freedom provided by recess 60 biases weight 66 radially outward against second arm 72 of bracket 62, and against the bias of spring 64. Bracket 62 thus also translates radially outward, and sealing arm 68 of bracket 62 uncovers or exposes bottom opening 70, allowing milk 15 to flow from internal compartment 14 into hollow region 18 of bottom portion 16. It will be appreciated that in certain embodiments, if bracket 62 contains enough mass, it may function as a weight itself, and will be biased radially outward against spring 64. In such embodiments, no weight 66 is needed.
It will be appreciated that the force applied by spring 64 corresponds to the equation F=kx, where ‘F’ is the force applied by the spring, k is a constant spring coefficient, and ‘x’ is the displacement of spring 64 (e.g., displacement of a section of spring mounted to second arm 72 of bracket 62). It will also be appreciated that a spring may be utilized which, absent relative rotation of top and bottom portions 12, 16 (or with minor or slow/steady rotation used to screw/unscrew top portion 12 to/from bottom portion 16), maintains sealing mechanism 20 in the closed position. However, spring 64 may also be sufficiently weak to enable a child to provide sufficient angular acceleration to top portion 12 to move sealing mechanism 20 from the closed position to the open position. Finally, it will be appreciated that either direction of rotation (e.g., clockwise or counterclockwise) will cause sealing mechanism 20 to move from the closed position to the open position. Sealing mechanism 20 is preferably mounted off-center to circular plate 38 (e.g., so that weight 66 is not disposed in the exact center of circular plate 38) to create the effects described above.
In certain embodiments, bottom portion 16 may include a horizontal thread operatively disposed below male threads 52 of bottom portion 16 and above bottom seal 56. For example, once top portion 12 has been fully screwed onto bottom portion 16, it may be configured to fully navigate female threads 52 and then drop onto such horizontal thread and be rotated continuously without being further screwed onto or unscrewed from bottom portion 16. Container 10 may be configured without seals 17, 56 so that when top portion 12 is rapidly rotated on the horizontal thread of bottom portion 16, there are no seals do not resist such rotation. Alternatively, low friction seals may be utilized which do not significantly inhibit rotation of top portion 12 on such horizontal thread.
It will be appreciated that the portable container disclosed herein may be utilized using a number of different methodologies. An exemplary methodology may include, for example, removing cap 30 from top portion 12, pouring milk 15 into internal compartment 14 of top portion 12 via exposed inlet 24, attaching cap 30 back onto inlet, pouring cereal 19 into hollow region 18 of bottom portion 16, placing top portion 12 over bottom portion 16, and slowly rotating top portion 12 relative to bottom portion 16 while bottom portion 16 is on flat surface 11. Such rotation is preferably done slowly and with relatively constant angular speed to ensure that sealing mechanism 20 does not release milk 15 into cereal 19. Once top portion 12 is fully screwed onto bottom portion 16 with seals 22, 56 touching one another, container 10 may be placed in a refrigerator for the night, and taken to school or work the following day.
Upon arrival at school or work, container 10 may be placed in a new refrigerator or operated in one of a number of different modes to create the cereal-milk mixture. A first mode of operation to create the milk-cereal mixture from the assembled container 10 utilizes a twisting motion as follows. With top and bottom portions 12, 16 fully assembled, top portion 12 may be quickly rotated in an unscrewing direction (e.g., counterclockwise) as shown in
In a second mode of operation, top portion 12 may be slowly rotated at relatively constant speed in an unscrewing direction. During such motion, sealing mechanism 20 will not move to the open position because not enough force will be generated to move bracket 72 against the bias of spring 64 (with or without weight 66). Once top portion 12 has partially traversed its threaded engagement with bottom portion 16 in the unscrewing direction, top portion 12 can then be quickly turned in the screwing (e.g., clockwise) direction, causing the sealing mechanism 20 to open and release milk 15. This second mode of operation may also be repeated one or more times to ensure all milk 15 has been emptied into cereal 19 in bottom portion 16.
In a third mode of operation, if bottom portion 16 is configured with a horizontal thread as described above (or with a gap between the threads as further described below), then once top portion 12 can be continuously rotated on a horizontal thread at a relatively high speed in either the clockwise or counterclockwise direction. Top portion 12 can then be pulled upward and turned in an unscrewing (e.g., counterclockwise) direction, whereby it will engage once again with male threads 52 and unscrew from bottom portion 16.
It will be appreciated that during operation of container 10 in any of these three modes, no parts are removed or ripped therefrom. Additionally, no portion of the container's interior is accessed, and milk 15 and cereal 19 are fully shielded at all times by top and bottom portions 12, 15, which remain detachably coupled to one another in threaded engagement. This will prevent spillage of the milk or cereal from the container 10, and enable the milk-cereal mixture to be formed at any convenient time. It will also be appreciated that other food items may be utilized. For example, instead of cereal in bottom portion 16, salad may be utilized. Instead of milk in internal compartment 14 of top portion 12, salad dressing such as an oil/vinegar mixture may be utilized. It will also be appreciated that container 10 may be used for non-food products where it is desired to keep the products separate until an appropriate time. In fact, if an oil/vinegar mixture is utilized in internal compartment 14, then even if such mixture separates overnight, rotation of top portion 12 to operate container 10 to mix the food items will cause the oil and vinegar to swirl inside internal compartment 14 before and while it is transferred through opening 70, thus making for a better salad-dressing mixture.

The container components described herein, including bracket 62, weight 66, and spoon 44 are preferably made of plastic, although other materials may be utilized. In certain embodiments, if container 10 will be operated by a very small child, then weight 66 may be permanently sealed inside sealing mechanism 20 so there is no chance that a small child tinkering with top portion 12 can remove it. As discussed above, sealing the mechanism may be permanently mounted within plate 38. In yet other embodiments, the sealing mechanism may be a removable spherical piece shaped like top portion 12.

Removable cap 130 of container 100 may include rib 134 and finger slots 131A, 131B which allow a user to grasp cap 130 and twist it off in an unscrewing (e.g., counterclockwise) direction, or to twist it in a tightening (e.g., clockwise) direction. Cap 130 includes external threads 133 which engage inner threads 135 of an upper neck portion 136 of top portion 112. Cap 130, once fastened to upper portion 112, can also be used to turn upper portion 112 clockwise or counterclockwise to screw or unscrew upper portion 112 onto or off of lower portion 116. Cap 130 may also be used to grasp and rapidly spin upper portion 112 in clockwise and/or counterclockwise directions in one of the three modes described above with respect to container 10, to continue turning upper portion 112 in a clockwise direction to lock it into bottom threads of lower portion 116, and/or to pull upper portion 112 upward while turning it to reengage threads and remove upper portion 112 (further described below).
Similar to top portion 12, top portion 112 is bowl-shaped and semi-spherical, but also includes upper neck portion 136 for receiving milk 15, screw-on cap 130, and lower neck portion 138 for receiving and securing internal reservoir or funnel 114 (
The threaded engagement of reservoir/funnel 114 and top portion 112 via engagement of lower neck portion 138 and upper neck portion 142, while detachable, is preferably rigid, and requires significant force to unscrew/detach such that reservoir 114 can only be removed by an adult or older child, and does not loosen during operation of container 100. The detachable engagement of reservoir 114 and top portion 112 may additionally or alternatively be accomplished by any suitable latching or interference fit mechanism known in the art which provides a secure engagement during spinning of top and bottom portions 112, 116 relative to one another. Once fixed to top portion 112, reservoir rotates with top portion 112 when top portion 112 is rapidly rotated as described herein.

Mechanism 120 also includes a spring 164 having a first end 164a mounted to a radially inner end 165 of housing 122, and a second end 164b mounted to a radially inner side of a retaining portion 167 of L-shaped bracket 126 as shown. Retaining portion 167 of bracket 126 is movably retained within and encapsulated by hollow housing 122, and allowed to translate radially outward along housing 122 when top portion 112 of container 100 is rotated. Spring 164 is also retained in and fully encapsulated by housing 122. A plug member 168 is provided on top of platform section 125 of L-shaped bracket 126 for forming a seal with aperture 144 when sealing mechanism 120 is in the closed position (with spring 164 retracted).
Plug member 168 may be integrally formed with bracket 126 or provided as a detachable piece. Plug member 168 may also be provided with an O-ring or a rib 169 at the top thereof for providing a seal with the bottom edge of aperture 114 when sealing mechanism 120 is in the closed position. It will be appreciated that rib 169 should be sufficiently large to prevent leakage or seepage of milk 15 from exiting aperture 114, but also small enough to allow plug member 168 to come out of aperture 114, and translate radially outward with bracket 126 to the position shown in
As shown in
As shown in
It will be appreciated that in sealing/release mechanism 120, there is no separate weight component as bracket 126 functions as the weight. In certain embodiments, portions of bracket 126 inside housing 122 may be made of a heavier weight material, whereas rib 169 and/or platform section 125, which will have some contact with the milk, may be formed from plastic. Housing 122 may also be made of plastic.
Container 100 is reusable and allows for easy detachment of reservoir 114 for washing. It will be appreciated that the shape and tilt of reservoir 114 will better bias milk toward aperture 144 during rapid rotation of top portion 112 (with reservoir 114) relative to bottom portion 116. Additionally, by mounting sealing/release mechanism 120 at a radially outer portion of top portion 112 (e.g., at a radially outer portion of reservoir 114 within top portion 112), release mechanism 120 is moved through a greater speed/acceleration for a given rotational speed/acceleration of top portion 112. For example, bracket 126 is moved/accelerated as a function of both the rotational velocity/acceleration applied to top portion 112 and the distance (radius) from the center of top portion 112 to the bracket 126. In this manner, the momentum and inertia of bracket 126 is greater at a radially outer position, being unable to move in a straight direction tangential to the direction of spin, is more easily biased radially outward to release the milk during rapid rotation of top portion 112.
The present invention has been described in the context of a number of embodiments, and multiple variations and examples thereof. It is to be understood, however, that other expedients known to those skilled in the art or disclosed herein may be employed without departing from the spirit of the invention.
Therefore, it is intended that the appended claims be interpreted as including the embodiments described herein, the alternatives mentioned above, and all equivalents thereto.
