BACKGROUND Field of the InventionThe Stackable Container System is in the field of containers, and more specifically, in the field of stackable containers.
SUMMARY OF THE INVENTIONAn embodiment of the modular container system comprises a plurality of container units with side openings; a lid component; wherein the container units are removably attached to each other forming a stack; and wherein the lid component is removably attached to the top container unit in the stack.
In an embodiment of the modular container system the container units each comprise: a bottom surface; a side wall extending upwardly from and adjacent to the edges of the bottom surface defining an interior volume and terminating in an upper edge; and a base wall extending downwardly from the bottom surface; wherein the base wall of a first unit may be removably attached to the side wall of a second unit adjacent to the upper edge thereof.
The side opening in an embodiment of the modular container system may comprise an opening in side wall of each container unit; an opening wall extending outwardly from the side wall adjacent to and around the opening in the side wall and terminating in an outer edge; and a cover removably attached to the opening wall adjacent to the outer edge.
Other embodiments of the modular container system are depicted wherein the inside surface of the base wall is provided with an engagement mechanism for attaching to an engagement mechanism provided on the outside surface of the side wall.
The stackable container system comprises a stackable container unit that may be combined with other similar stackable container units to form a container with multiple separate chambers. Each container unit has its own chamber to hold powders, foods, or other items, and may be individually accessed through an opening in the top when not stacked, and through a dedicated opening in the side thereof when stacked with other container units.
Each unit is open on top with a sealed bottom. The bottom of each unit may be removably attached to the top of another unit, such that the bottom of the unit becomes the lid of the unit below it. Multiple container units may be attached in this way to form a stack of container units.
The top unit of the stack may be provided with a lid to seal the top opening. The lid may be provided with a plurality of compartments for storing items, including vitamins, supplements or other pills.
Each container unit may be provided with a side opening with a removable lid attached thereto, allowing the contents of the unit to be accessed without removing the lid or other unit from the top of the container.

The unit 100 is provided with a base 110 formed by bottom panel 104 and base wall 112 extending downwardly from a bottom surface of bottom panel 104. The inside surface of side wall 112 is provided with an engagement mechanism 114 to engage the engagement mechanism 108 on a second unit 100 to be stacked below the first unit 100. In the embodiment depicted in the figures, engagement mechanism 114 comprises threads on the inside surface of side wall 112 forming a female threaded area. The female threaded area 114 on the base 110 engages the male threaded area 108 on the top of the unit 100 below in the stack and seals the top opening of the lower unit 100. In one embodiment, the mechanism 108 and mechanism 114, when fully engaged, hold the units 100 with the side opening 116 of each unit 100 in line with the side opening 116 of the other units to which it is attached along the longitudinal axis of the containers.
Each unit 100 is provided with a side opening, or aperture, 116 for accessing the interior space 102 without removing the unit from the stack of connected units. The side opening 116 is provided with a removable cover 118 for securing the unit 100 in a sealed configuration. The cover 118 may be provided with an optional retention strap 120 to prevent loss of the cover 118 when it is not affixed over side opening 116.
Cover 118 may be provided with retention band 120 for retaining the cover when it is removed from side opening 116. Retention band 120 may be provided in a variety of designs. The embodiment depicted in the figure incorporates a retention band 120 that is pivotally attached to two fittings 212 which may be attached to or formed as part of each unit 100. The specific design of the retention band 120 and the manner of its attachment to each unit 100, is not limiting of the invention described herein.
The top unit 100 in a stack may be provided with a lid 122 to cover the top opening thereof. The lid in the embodiment shown in the figures is formed from a lid surface 124 and a side wall 126 extending downwardly from the lid surface 124 forming a component similar in configuration to the base 110. In the depicted embodiment, the inside surface of lid 122 is provided with a female threaded area for engaging the male threaded area 108 on the top unit 100 in the stack.

In the depicted embodiment, side opening 116 comprises a hole 206 in side wall 106 of the unit and side wall 208. The hole 206 may be of varying shapes, including rectangular, oval, circular or any other shape suited to access to the interior space 102 of a unit 100. Wall 208 extends in a substantially perpendicular direction from side wall 106 adjacent to and around hole 206, forming a hollow tube-like structure.
Cover 118 is provided to seal the end of wall 208. Cover 118 may be designed in a number of alternative embodiments to seal the end of the tube-like structure formed by wall 208. Any cover design suitable for such purpose and known to those in the field of such covers may be utilized. In the embodiment shown in the figures, cover 118 is provided with flange 210 for accepting the end of wall 208 and sealing the tube-like structure.
Lid 122 is installed on the top unit 200 in the stack of units. In the depicted embodiment it is provided with a top surface 124 that covers the top of unit 200, and a side wall 126 extending downwardly from the top surface 124. The inside surface of side wall 126 is provided with an engagement mechanism for engaging the engagement mechanism 108 on the unit 200. Other types of lids may be provided, for example, a rubber lid that stretches slightly to fit over the top of unit 200 and is maintained there by elastic tension.
