The sidewall 150 comprises a pair of two wide walls 152 and of two narrow walls 162. The wide walls 152 are opposed and parallel to each other (i.e., they defined opposed walls). The narrow walls are 162 are opposed and parallel to each other.
The wide walls 152 each comprises an external face 154 which, about the top 110, extends inwardly in a pair of handles 172 (i.e., two handles), wherein the two handles are inwardly shaped surfaces 174 extending continuously from one of the side walls 152 and providing a place for someone to put at least partially their fingers in the handle 172 to lift the stackable container 100.
The handles 172 are both slanted relative to horizontal (slant angle 190) and with the uppermost portion of the handles 172 being close to the center of the wide walls 152 equidistant from the narrow walls 162, and the lowermost portion of the handles 172 being closer to the narrow walls 162 (slant angle 192).
According to a realization, as depicted on
According to a preferred realization, the handles 172 located on a wide wall 152 are distant from each other, with the inwardly shaped surfaces 174 of the handles 172 extending outwardly when close to each other in a joining face 176 being about or slightly inward relative to the external face 154 about the joining face 176.
The handles 172 are further designed to be located back-to-back on opposed wide walls 152 such that someone may either place right-hand fingers in one of the back-to-back handles 172 and left-hand fingers in the other one of the back-to-back handles 172 or the contrary.
Furthermore, the width of the receiving surfaces 112 and the distance between the handles 172 and the receiving surfaces 112 is selected such that someone is able to lift and hold a stackable container 100 using their thumb inserted in a first handle 172 and their other fingers of the same hand in the handle 172 that is back-to-back with the first handle 172.
According to a realization, the depth and inclination of the top portion of the inwardly shaped surface 174 allows someone to insert their fingers ergonomically in the handles 172 located on the same wide wall 152 and to pull and/or hold the stackable container 100 using their two hands. The shape, angle, and relative location of the sloped surface 116 relative to the handle 172 further provides a hinderance that prevent the side of a hand holding the stackable container 100 to slide and abut the neck 122.
Finally, in a similar fashion, the stackable container 100 allows someone to use both hands to hold a stackable container 100 having their fingers inserted in handles 172 located on one wide wall 152 and the thumbs inserted in the opposed handles 172 with the arms and wrists having an acute angle therebetween that is utmost ergonomic.

For all embodiments, it is worth noting that regardless of relatively sharp edges defining limits between the wide walls 152, and the narrow walls 162, and even the resting surfaces 132 and the clearance surface 136, other embodiments may feature smoother edges, and even continuous curved walls ensuring smooth transitions. Therefore, e.g., the sum of the walls 152, 162 may have a general shape of, e.g., an ellipse without departing from the scope of the previous description.
It is also worth noting that the apexes 114 and 134 are currently defining a central line allowing the stackable containers 100 to vertically align one another since the apexes result in the top stackable container naturally slipping until the apexes 114, 134 are aligned. In embodiments where apexes 114, 134 are not defining a central line, the apexes 114, 134 must be offset of the same value and in opposed direction (frontward and rearward) on the left side and the right side of the stackable container 100.
It is also worth noting that the receiving surfaces and 112 and the resting surfaces 132 may have a variety of shapes comprising a V shape and an inverted U shape.
It is also worth noting that the number of apexes per surface may be greater than one, based on the distance between the walls 152, as long as the number of apex(es) 114 on the receiving surfaces 112 are designed to be aligned with the apex(es) 134 of the resting surfaces 132.
It is also worth noting that regardless of the present description defining, by contrast, the wide walls 152 and the narrow walls 162, the junction between the wide walls 152 and the narrow walls 162 may be ambiguous, such as an edgeless sidewall 150 without departing from the present description, with the limits of the wide walls 152 and the narrow walls 162 being a question of opinion.
Similarly, the characteristics of wide and narrow are for teaching purposes only in accordance with the figures. In realizations, the walls 152, 162 may have a relatively similar width, and may even be opposed in dimension without departing from the teaching of the present description.
It is worth noting that, when pouring fluid from the handles 172 by handling the stackable container 100 by the side, the location of the handles 172 (about the top 110 but distant from the top 110) and the slope of the top portion of the handles 172 define a narrowing conduit for the passage of fluid that is wide enough to allow controlled flow of the fluid. Furthermore, the slope of the clearing surface 132 provides a great surface for someone to put their hand and lift the stackable container 100 to use as a lever relative to the other hand to slant the stackable container 100.
Alternatively, when pouring from the front, the space between the handles 172 and the surface 174 provide a funnel-like structure easing the process of pouring fluid therefrom.
In consequence, the stackable container 100 is well adapted to pour fluid from both sides and alternatively from the front with the shape of the interior wall providing an aid in providing controlled flow when pouring.
While preferred embodiments have been described above and illustrated in the accompanying drawings, it will be evident to those skilled in the art that modifications may be made without departing from this disclosure. Such modifications are considered as possible variants comprised in the scope of the disclosure.
This application claims priority from U.S. provisional patent application 63/154,387 filed Feb. 26, 2021, the specification of which is hereby incorporated herein by reference in its entirety.
