sum 2 or 2 IN v m 'r (m 7 JOSEPH GEORGE FERRARO CONTAINER BACKGROUND OF THE INVENTION This invention relates to a container construction and, more particularly, it relates to a container which is constructed for selective nesting, stacking and gripping.
Broadly stated, the present invention relates to a container adapted for nesting and stacking with other similarly shaped containers, said container comprising a front face and a rear face, each of said front and rear faces having a substantially flat surface, the periphery of each of said front and rear faces forming a polygon, a plurality of integral substantially flat wall portions connectively engaging said front and rear faces, the number of said wall portions being equal to the number of sides in said polygon, at least two wall portions extending beyond the surface of said front face, oblique surface panels connecting said two wall portions with the surface of said front face, all other wall portions being attached to said front face at a common line of juncture, and said plurality of wall portions being similarly attached to said rear face.
In accordance with the present invention, the container is constructed so that at least two nonadjacent sides of a container having a polygonal configuration are laterally extended beyond the remaining side in order to provide a suitable gripping structure as well as a structure whereby a plurality of similarly constructed containers can be stacked and/or nested. Preferably, the container will be in the form of a polygon having an even number of sides with every other side being constructed with extensions. Accordingly, the alternating extensions of the sides are constructed so that they are of a size and shape to form a joint-type fitment with similarly constructed containers. A plurality of containers can be nested by intermittent fitting of containers. The container walls are of sufficient width to provide stability for stacking.
The present container construction is useful in that the features of the individual containers enable stable nesting or stacking in either vertical or horizontal positions for display purposes, storage purposes and shipping purposes. Since a plurality of containers can be nested horizontally in a stable alignment there is no need for partitions between each container in shipping cases. The homemaker is provided with space economy when several containers are purchased and each container is constructed so that the homemaker also is provided with a special gripping feature for controlled pouring of contents.
BRIEF DESCRIPTION OF THE INVENTION The structural features and advantages of the invention will be better understood from the following detailed description of a typical embodiment of the invention, as now contemplated, taken in conjunction with the accompanying drawings in which:
FIG. 1 is a front elevational view of a nestable container constructed in accordance with the present invention;
FIG. 2 is a side elevational view of the container shown in FIG. 1 in a nesting relationship with a similarly constructed container;
FIG. 3 is a top view of the container shown in FIG. 1;
FIG. 4 is a bottom plan view of the container shown in FIG.
FIG. 5 is a fragmentary cross-sectional view drawn to a larger scale and taken along the line 5-5 of FIG. 1;
FIG. 6 is a broken perspective view showing the nestable container with a hand gripping one side of the container;
FIG. 7 is a perspective view showing a plurality of containers in aligned, nested and stacked relationships.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, wherein like reference numerals designate similar parts throughout the various views, and primed reference numerals refer to opposite identical structures, the figures illustrate nestable container 10 of substantially octagonal configuration. Container 10 of the instant invention has a substantially flat front face 11 and a similar rear face 12 (FIG. 6). Connecting the front and rear faces of the container is a plurality of substantially flat wall sections disposed in planes perpendicular to the front and rear faces and arranged to provide the octagonal configuration as shown in FIGS. 1 and 7. These interconnecting wall sections include top wall 13, bottom wall 14, and sidewalls l5, l6, I7, 18, 19 and 20. Top wall 13 is provided with material outlet 21 which may be conventionally externally threaded (FIG. 6) and having a conventionally threaded cap 22 provided for the outlet 21 (FIGS. 1 and 2 As principally shown in FIGS. 1--4, top wall 13, bottom wall 14 and sidewalls l6 and 19 connectively engage front face 11 and backface 12 by a common line of juncture or edge. Sidewalls 15, 17, 18 and 20 have continuous lateral extensions which connect with front face 11 and backface 12 by intermediate oblique surface panels.
In the embodiment shown, sidewall 15 is formed with lateral extensions 30, 30 terminating at edges 31, 31 which are connected to downwardly and inwardly directed panels 32, 32' (FIG. 6) and end panels or chamfer portions 33, 34 and 33', 34' (FIG. 6).
The extended sidewalls 17, 18 and 20 have structural features similar to sidewall 15. Sidewall I7 is formed with lateral extensions 35, 35' terminating at edges 36, 36' which are connected to downwardly and inwardly directed panels 37, 37' and end panels or chamfer portions 38, 39 and 38, 39. Sidewall 18 has lateral extensions 40, 40 terminating at edges 41, 41 which are connected to downwardly and inwardly directed panels 42, 42 and end panels or chamfer portions 43, 44 and 43, 44. Sidewall 20 has lateral extension 45, 45 terminating at edges 46, 46' which are connected to downwardly and inwardly directed panels 47, 47 and end panels or chamfer portions 48, 49 and 48', 49.
The structural arrangement of the lateral extensions is such that each extension (e.g., extensions 30, 30) is characterized by an extended area having a substantially trapezoidal configuration. This configuration with its connecting panels (e.g., elongated panels 32, 32' and chamfer portions 33, 34 and 33, 34') enables a snug engagement with a side not having extensions and may form, in effect, a joint-type fitment of a scarf characteristic (FIGS. 2 and 7).
As shown in FIG. 2, the lateral extension arrangement enables containers to be nested, one next to the other. In particular, FIG. 2 shows a side elevational view of container 10 and a broken partially cutaway side elevational view of similarly constructed container 10(a) which has been slightly rotated and nested with container 10. By slight rotation of one of the similarly constructed containers, it is possible to nest two or more containers.
Container 10 nests with container 10(a) when container 10(a) is rotated so that the edge 41(a) of lateral extension 40(a) of side 18(a) is adjacent to the line of juncture between sidewall 19 and the backface of container 10. Similarly panel 44(a) of side 18(a) of container 10(a) is adjacent to panel 48' of side 20 of container 10 and panel 43(a) of side 18(a) of container 10(a) is adjacent to panel 44' of side 18 of container 10. In a corresponding manner the edge of the lateral extension of side 20 of container 10(a) will be adjacent to the line of juncture between the top wall and the backface of container 10. The chamfer portion 48(0) of side 20(a) of container 10(a) is adjacent to the panel or chamfer portion (49') of side 20 of container 10. In a corresponding manner the edges of the lateral extension of container 10(a) will be adjacent to the respective lines of juncture between the nonextended walls and the backface of container '10. The arrangement is such that the two containers are suitably nested for display, storage and transportation. If desired, two or more containers may be packaged in a nested relationship by band wrapping, overwrapping or shrink wrapping.
As readily depicted in FIG. 6, the lateral extension structural arrangement provides a suitable gripping structure for either left-handed gripping (as shown) or right-handed gripping (not shown). A wall (115) with extensions (30, 30') provides adequate breadth for either one or two fingers, the elongated panels (e.g., panel 32) are adequate for thumb fitment and a chamfer portion will conveniently fit a finger. To use the container the operator merely picks up the container with the thumb and fingers sliding into a stable gripping position (as shown in H0. 6) and can tilt the container either face downwardly or side downwardly until the product flows through material outlet 21.
FIG. 7 shows, in perspective, a plurality of containers intermittently fitted in various relationships. It is illustrative of aligned containers, nested containers and stacked containers. It is to be understood that although the containers shown in the drawings utilize a material outlet extending from one wall, it will readily be apparent to those skilled in the art that this container can be modified to have 37 plug" type closures for a material outlet which is within a wall and not upstanding. Various opening and closure systems are well known and this invention is not to be construed as limited to any particular system.
The thickness of the faces and walls of the container should be sufficient to enable the container (whether empty or having contents therein) to substantially maintain its configuration so that no distortions occur in transit, in storage, in stacked or nested positions. As shown in FIG. of the drawings the extended portions are hollow and provide additional space for the contents. However, the area formed by the extensions and oblique surface panels may be solid or the edges of the extensions may be reinforced by an added thickness to facilitate edge-to-edge stacking. Preferably, the extended portions of a latera extension is less than half the width of a sidewall not having any extended portions. ln general the width of any side is sufficient for upright standing support and the extended portions add sufficient areas for nesting.
Material outlet 21 preferably will not extend from top wall 13 or any other wall beyond the area between the intersection of the planes formed by the next adjacent sidewalls l5 and 20.
Container is an integral structure preferably formed by blow molding of a suitable tough resilient plastic material so that the container will substantially retain its shape. The interconnecting portions of the wall sections, i.e., those portions extending from corner to corresponding corner of the octagonal contour, are substantially straight but due to molding techniques may have a slight deviation from the straight. The plastic material should be impervious and inert with respect to its contents. The containers may be formed by other molding practices such as vacuum, compression or injection molding but blow molding is preferred as less expensive and entirely adequate. While plastic materials (such as polypropylene, polyethylene, polyvinyl chloride, or some material having equivalent properties) are preferred, other material (e.g., metal and glass) which are capable of construction for the purpose intended are suitable.
The product packaged in the container may be of any suitable character such as liquids or pulverant materials. Where the product includes more volatile ingredients the interior of the container may be lined or coated. Such liners or coatings must be chemically inactive with respect to the ingredients of the container. Materials such as various vinyl chlorides, vinylidene chloride or epoxy resins may be used for lining or coating the container.
The present preferred embodiment as herein described in conjunction with the drawings shows a container having a substantially octagonal configuration, The length of the walls may be of equal lengths or unequal lengths. While an eight-sided configuration is presently preferred, the container may be in the form of other polygons, e.g., polygons having more than four sides such as six to 12 sides. The polygon must have sufficient sides to provide the container with the desired strength to permit side stacking or nesting as well as upright stacking or nesting.
