Definitions

  • the present invention is concerned with various forms of cartons, containers and enclosures formed of panels, particularly where the panels are adapted for repeated reuse and the invention is concerned with systems and devices for assembling and interconnecting the panels at a corner of a container in a manner providing simple and sturdy panel interconnection and simplicity in panel separation.
  • One of the important objectives of the invention is to provide a novel interrelationship of panel parts and of interconnecting or fastening devices which greatly increases the strength and rigidity of the containers formed while at the same time providing for ready separation and reassembly of the container components.
  • components such as the panels employed are arranged and proportioned to provide a modular system in which various of the panels may be employed in various combinations providing containers of various different sizes and shapes.
  • a system for interconnecting panels, particularly panels of a carton or container where the panels are arranged in edge-to-edge relation either in the same plane or in planes at angles to each other where such angle lies between the same plane (180 degree relationship) and the typical 90 degree relationship at the corners of conventional cartons.
  • Panel interconnecting systems are well known, especially for the interconnection of panels along the corners or edges of a rectangular container where the panels extend from each other usually at angles of 90 degrees.
  • Such known fastened systems customarily include connector plates which are fastened to the panels near the 90 degree corner, together with a spring clip extended around the corner and engaging the connector plates.
  • US-A-4024977 discloses a knock-down container in which spring clip fastening devices are used at the corners thereof to link wall panels of the container.
  • the disclosure of this patent is particularly concerned with the shaping of spring clips to avoid inadvertent injury during their removal.
  • corner plates which are a feature of this invention provide for convenient and simple application and ready separation of a corner joint, thereby contributing to the ease of assembly of shipping cartons and ready separation of the parts for reuse in subsequent packaging.
  • corner plates which are a feature of this invention provide a system for interconnection of panel pieces of various different sizes and shapes, so that the fastening devices can be employed in the assembly of containers of various sizes and shapes in some of which different numbers of panel pieces are used.
  • the invention is of particular advantage in the interconnection of panels lying in planes at 90 degrees to one another, nevertheless the invention provides connectors which can also be used for interconnection of panels lying in planes in a range from 180 degrees to 90 degrees or even at angles sharper than the 90 degree relationship.
  • fastening devices featured in the following claim 1 are applicable not only to cartons but also to a wide variety of enclosures or the like, such as boxes, containers, vessels, structural partitioning or enclosures, used, for example, for human occupancy, and the use of the term container(s) herein is not to be understood in a limited sense.
  • Figures 1 to 9 correspond to the Figures disclosed in my prior United States Patent No. 4,584,806, and are particularly concerned with the use of panel interconnecting or fastening devices employing bridge plates extended across panel joints where the panels lie in a common plane or in planes extended at angles greater than the 90° relationship of rectangular containers, as follows:
  • Figures 10 to 30 are views illustrating various features and aspects of the present invention, many of which are adapted for use in combination with features illustrated in Figures 1 to 9, Figures 10 to 30 being further identified as follows:
  • the invention contemplates employment of spring clip fastening devices which, are adapted for the interconnection of panels adjoining each other at the upright corners of a container defining a generally rectangular container volume.
  • corner fastening devices of the kind just referred to, at the upright corners of a rectangular container, increases the strength of the container and, at the same time, provides facility for incorporation of various panels in a variety of interrelationships and thereby provides a modular system adapted to the formation of various containers of different sizes and shapes while employing components, such as the panels and also the fastening devices, of the same or similar construction.
  • the fastening devices are preferably formed of sheet metal and, in general, the components of the fastening devices are relatively thin as compared with the panels of which the containers are made.
  • the panels 10-10 lie in a common plane and meet at a joint 11, the fastening device being associated with the edges of the panels near the joint.
  • Each of the devices for interconnecting the two adjoining panels includes four components comprising a pair of connector plates, one mounted near the edge of each panel, a bridge plate spanning the joint between the panels and a spring clip for holding the parts in assembled relation.
  • Each connector plate is generally indicated by the reference numeral 13.
  • Each connector plate includes a metal channel 14 having flanges 15 with marginal strips 16 apertured to pass the fastening screws 17 by which the connector plates are secured to the panels.
  • each connector plate is mounted on the panel in a position so as to define cavities lying along the panel and having openings presented toward each other across the panel joint.
  • Each connector plate also has apertures 18 formed therein and adapted to cooperate with the fastening means provided at the ends of the spring clip 19 which comprises the fastening component of the joint.
  • the spring clip 19 is provided with a bent hook 20 at one end and also with a detent 21 at the other end.
  • the hook 20 is first engaged in one of the apertures 18 in one of the connector plates, and the detent 21 is then inserted into the aperture 18 of the other connector plate.
  • the spring clip 19, as best seen in Figures 2, 3 and 6 has a curvature facilitating the insertion of the detent when the parts are being assembled, and this curvature will vary according to the angle of the panels being connected.
  • each connector or spring clip 19 is shown as having a hook at one end and a detent at the other end, but it is to be understood that the interengaging means at the ends of the connector or spring clip may take the form of a detent at both ends.
  • the connector plates and the spring clip comprise the components which hold the panels together at opposite sides of the joint 11, the spring clip preferably being configured so that the edges of the panels are brought together into snug engagement without clearance.
  • the connector plates and the spring clip will provide an effective connection between the two panels, as above described, the panels, being extended in a common plane or in edge-to-edge relation in somewhat inclined planes (as described hereinafter with reference to the embodiment shown in Figures 7, 8 and 9), would still remain free for relative shifting movement of the panels either angularly or transversely with respect to each other in the absence of some fastening means in addition to the spring clip.
  • a bridge plate is provided. In the arrangement of Figures 1 to 6, this bridge plate is indicated by the reference numeral 22. It will be seen that the bridge plate comprises a channel-shaped component extended across the panel joint and into the cavities provided within the connector plates.
  • the bridge plate also has apertures 23 formed therein and, as seen in Figure 6, those apertures are in registry with the apertures 18 in the connector plates when the parts are assembled at the panel joint.
  • the apertures 23 are larger than the apertures 18 in a direction transverse to the joint between the panels, the apertures 23 being positioned and proportioned so that they will not restrict or interfere with the action of the spring clip 19 in its cooperation with the apertures 18 when the spring clip is applied to complete the panel joint.
  • the presence of the apertures 23 and the projection of the fastening elements 20 and 21 of the spring clip not only into the apertures 18 at the connector plates but also into the apertures 23 of the bridge plate serves the purpose of preventing the bridge plate from escaping by unintentional displacement out of the openings provided within the connector plates 13.
  • the bridge plate is desirably dimensioned in a direction perpendicular to the panels and to the connector plates so that only very small clearance is provided between the top of the bridge plate and the under side of the connector plates. Providing only small clearance is of importance in preventing the panels from shifting in relation to each other in a direction perpendicular to the plane of the panels or in angularly tilting with respect to each other.
  • the wall of the container there shown is made up of a panel 10a, having an area equal to one-half of the total side-wall of the carton, together with two panels 10b, each of which represents about one-quarter of the total area of the wall.
  • the spring clips and connector plates of the joints serve to interconnect the three panel pieces 10a, 10b and 10b, but as will be realized from inspection of Figure 1, the same parts mounted on other panel pieces lying in the same plane may alternatively be used in order to interconnect panel pieces in different arrangements.
  • panel pieces each representing one-quarter of the area of the wall
  • a wall such as indicated in Figure 1 could be formed by means of two panel pieces such as shown at 10a, each comprising one-half of the wall, instead of employing the one-quarter size pieces indicated at 10b.
  • Various combinations may thus be employed in a container in accordance with the invention.
  • the panels 10'-10' are positioned in planes at an angle to each other and may have bevelled edges providing a joint 11'. It will thus be seen that the arrangement shown is readily adapted to the interconnection of panels lying either in the same plane or in somewhat angled planes. Although the angle of the panels in the embodiment of Figures 7, 8 and 9 provides a convex configuration when viewed, as in Figure 9, it will be understood that some angularity in the concave sense may also be accommodated by joint parts.
  • a spring clip fastening device of the kind described above including a bridge plate such as shown at 22 in Figures 2 to 6 and 22' in Figures 7 to 9 is preferred for joints where the panels lie in a common plane or at a somewhat inclined plane as in Figures 7 to 9, where the joint between the panels to be connected comprises a 90° or right angle joint, as in typical rectangular containers
  • a spring clip fastening device of a different form not including a bridge plate.
  • Such fastening devices are somewhat diagrammatically illustrated at 24 in Figure 1. While certain known right-angle fastening devices may be used for certain purposes, according to the present invention it is preferred to use 90° fastening devices of the kind fully described and explained in connection with various of the embodiments of containers as described hereinafter.
  • FIG 1 there is also shown at 24 a number of corner joint fastening devices, and while these may comprise corner clip fastening devices of certain known types, it is preferred to employ the type of spring clip fastening devices which are a feature of this invention hereinafter particularly described in connection with Figures 10 to 30 (see especially Figure 11 and Figures 16 to 24 inclusive).

  • This container is rectangular in cross-section and each of the sides of the container are formed by employment of two superimposed panels 26, all of which are preferably of the same construction and dimensions.
  • three of the walls of the container are shown as completed by the incorporation of a pair of superimposed panels 26, and the fourth side of the rectangle is shown as having the lower panel already installed, and the upper panel shown separate from the container prior to assembly.

Panels may be molded or extruded of plastic comprising both the boards 26 and the battens 27.
  • Figure 10 represents one form of a container which may be constructed using corner spring fastening devices contemplated by the present invention.
  • One of the important aspects of the present invention providing for a highly flexible modular system relates to the manner of joining or connecting the panels at the, four 90° upright corners occurring at the junction of the side walls defining a rectangular volume.
  • the invention contemplates certain distinctive features employed in combination at each one of these upright corners, and the features in question are explained herebelow with particular reference to Figure 11.
  • Figure 11 is a fragmentary enlarged view of the panel and joint parts at one of the upright corners of the container.
  • the panel boards 26 and the reinforcement strips 27 are differently configured at the opposite ends of the panel.
  • one end, shown at the left side of Figure 11, of the panel board 26 and the reinforcement strip 27 are both terminated or cut-off in a plane perpendicular to the panel.
  • These end surfaces are indicated at 26a and 27a, and these surfaces are adapted to abut against the inside surface of the panel 26 at the other side of the corner, as is indicated by the dot and dash lines between the two panels shown in Figure 11.
  • the panel board 26 of the right-hand component shown in Figure 11 may also be notched as indicated at 26b in a configuration conforming with the adjacent parts of the left-hand panel when the two panels are brought together to complete the joint. This notching will accommodate a reinforcement strip extended downwardly of the edge of a lid or cover for the container described hereinafter with particular reference to Figure 18.
  • a spring clip fastening device as described hereinafter is provided at the joint shown in Figure 11, but before explaining the preferred structure of the fastening parts, it is here pointed out that the two end configurations of the panels shown in Figure 11 are provided on each panel, one configuration being provided at one end of the panel and the other configuration at the other end of the panel.
  • the panels overlap each other at the corners of the container in a series extended in one direction around the four upright corners of the container.
  • This serial overlap is preferably employed in combination with certain features now to be described with reference to the fastening devices which, as will be explained, involves a serial overlap of parts extended around the container in the direction opposite to the overlap series of the panels themselves.
  • Each 90° fastening device is made up of three components, i.e., a pair of fastening plates and an interconnecting spring clip generally indicated at 30 in Figures 11 and 23.
  • the two fastening plates 28 and 29 are basically of the same configuration, comprising a stamped sheet metal piece having an aperture 31 and if desired, certain reinforcing ribs or the like such as indicated at 32, as well as holes 33 (see Figures 20 - 22) provided for attachment screws for securing the fastening plates to the panel pieces to be interconnected.
  • these two fastening plates 28 and 29 are identical in configuration, except for the bending or flexing of an end portion 29a on one of them adapted to overlie the end surface at one end of each panel as seen toward the right of Figure 11.
  • this overlapping of the fastening plate 28 of the left-hand panel shown in Figure 11 with respect to the end surfaces of the right-hand panel shown in Figure 11, provides an overlapping interrelationship which occurs in a series extended around the upright corners of the container in a series the direction of which around the container is opposite to the overlapping series of the panels themselves as above described.
  • the arrangement of these two overlapping series to extend in opposite directions around the container provides rigidity and integrity of the panel assemblies making up the containers, and this desirable characteristic is present in all embodiments of containers which may be produced in accordance with this invention.
  • the joint is also sturdily secured by the application of the spring clip such as indicated at 30 having detents 34 at both ends which are adapted to engage in the apertures 31 and thus retain the adjoining ends of the panels at the upright corners in the desired 90° relationship.
  • the bent edge portion 29a not only serves to facilitate positioning and mounting of the plate 29 at the end of the batten 27, but this bent edge 29a provides protection for the covered underlying corner or edge of the batten 27.
  • This covered edge of the end of the batten is a prominently exposed portion of the panel which otherwise would be subject to abrasion in the handling and shipment of the container. From Figure 11, it will be seen that the end portion of the panel 26 and batten 27 at the left side of the joint shown in Figure 11 are not subject to such abrasion, because of the overlap of the portions of the panel and batten at the right hand side of Figure 11.
  • fastening plates for the connecting devices be arranged and connected with the opposite ends of each panel in order to provide the overlapping arrangement fully described above and illustrated in Figure 11 in a manner providing the overlapping series extended around the container in a direction opposite to the overlapping of the end portions of the panels themselves.

Notwithstanding that only two different panel sizes are employed, the sides of three different container configurations may readily be formed. The same interrelationships between the panels and the containers themselves are also present in the three containers identified by the letters d, e and f in the lower portion of Figure 15.
