Abstract

A collapsible container includes a plurality of collapsible walls, each pair of adjacent walls connected by a latch. Each latch can be selectively actuated from contact with the latch both from inside and the outside of the container, and further by inwardly directed forced to the outside of the wall first to collapse. Preferably, the latch includes a recess into which the adjacent wall is disposed when the latch is in the latched position. Preferably, the latch is unlatched by flexing the latch away from the adjacent wall by application of force on an inner release surface, inward of the recess or by actuation of an outer release surface, outward of the recess, or by the application of an inwardly directed forced to the walls that are first to collapse.

Description

COLLAPSIBLE CONTAINER
BACKGROUND OF THE INVENTION
The present invention relates generally to a collapsible container for storing and transporting goods.
Portable storage devices that collapse are well known. Four walls each connected by a hinge to a base are selectively movable about the hinge between a use position, in which the wall is generally perpendicular to the base, and a collapsed position. Various mechanisms have been provided to connect adjacent walls at each corner to selectively lock the container in the use position.
Many such storage devices unlatch from outside the container, which is sometimes more efficient for a user, but not usable with automated equipment. Other such storage devices unlatch from the inside, which is often desired for use with automated equipment, but less convenient for human users. Further, some containers do not require unlatching at all, but instead are of the knock-down variety which collapsible under suitable force to the wall to sufficient overcome the latch. Moreover, such storage devices may have hinge mechanisms that are difficult or inefficient to manufacture or clean.
Some collapsible containers have walls that may be inwardly folded in order to stack the containers in an efficient and space-conserving manner when not in use.
This efficient means of storage is most easily achieved when the container has walls that do not overlap. However, many collapsible containers have relatively tall walls which when assembled, provide a large container volume and depth. Accordingly, when folded, at least one of the pairs of opposed walls will overlap.
Unfortunately, the overlapping walls typically result in less efficient stacking of the collapsed containers, because the overlapping second wall will be forced to sit high upon the first wall. Accordingly, the package height and the resulting stacking height of the collapsed unit will be relatively high. Containers that attempt to resolve the overlapping issue have been restricted, often requiring that the walls be folded in a particular sequence, or by having an unsymmetrical design or walls of varied heights. While some of these solutions may be adequate, they may not provide the desired level of strength and rigidity.

Some containers also have a drag rail on their bottom surface that allows a container to be stacked with a like container when assembled, whereby the drag rail of an upper container will sit within the opening defined by the assembled walls of the lower container. While this provides some stability to stacked containers, this design may not be appropriate in every situation. It may also not allow for stable stacking of collapsed containers.
Accordingly, a collapsible container is desired that has versatility in the latch, that is able to accommodate overlapping opposed walls such that they are able to be collapsed and stacked efficiently and comparable or better than those containers not having overlapping opposed walls. It would also be desired for the container to provide the desired level of strength and rigidity. Further it is desired to provide means by which to stack assembled or collapsed containers with some stability.
SUMMARY OF THE INVENTION
It is an object according to the present invention to provide a collapsible container that has a versatile latch suitable for various scenarios by a user.
It is another object according to the present invention to provide a collapsible container having a system of interlocking containers in an assembled stack and a collapsed stack.
It is an object according to the present invention to provide a collapsible container that provides for the walls to be collapsed in an efficient manner and a relatively low package height for purposes of stacking and storing.
It is another object according to the present invention to provide a collapsible container having at least one pair of opposed overlapping side walls which are able to be folded in an efficient manner to provide a relatively low package height.
The present invention provides an improved portable storage device with latch mechanisms selectively connecting adjacent walls at the corners wherein the latches can be actuated from both the inside and from the outside of the crate, and the latch can also be operable in order to define a knock-down style device.
Thus, this collapsible container can be used with automated equipment while still being efficient for a human user.

The present invention is also directed to a portable storage device having at least one interlocking member adjacent the latch. The interlocking member is inwardly offset from the outer surface of the wall so that when the walls are collapsed onto the base, the interlocking members will not interfere with the upstanding flange of the base nor will the base modification due to the interlocks be necessary, thus providing for a more rigid and sturdy base.
The collapsible container according to the present invention generally comprises a base wall and generally perpendicular first and second walls. A
latch mechanism is integrally molded with the first wall and connects the first wall to the second wall. The latch mechanism includes a recess into which a portion of the second wall is received, thereby latching the first wall to the second wall.
The latch mechanism further includes an outer release surface outward of the second wall and an inner release surface inward of the second wall, thus permitting the latch mechanism to be selectively disconnected from the second wall when the walls are assembled upon application of force to the outer release surface or the inner release surface, or to the outer wall surface due to the knock-down characteristics of this type of latch.
According to one aspect of the present invention there is provided a container comprising a base having a floor; a first wall generally perpendicular to the floor when in an assembled orientation; a second wall generally perpendicular to the floor and the first wall when in the assembled orientation; and a latch integrally molded with the first wall for selectively connecting the first wall to the second wall, the latch including an outer release surface disposed outwardly of the second wall, an inner release surface disposed inwardly of the second wall, and a second inner release surface disposed inwardly and adjacent the second wall, where the latch is configured to selectively disconnect the first wall from the second wall upon actuation of the outer release surface, and where the latch is configured to selectively disconnect the first wall from the second wall upon an application of force to the inner release surface, and where the latch is configured to selectively disconnect the first wall from the second wall upon force inwardly-directed upon the second wall sufficient to flex the latch away from the second wall by engagement of the second wall against the second inner release surface to release the second wall.

According to a further aspect of the present invention there is provided a collapsible container comprising a floor; a first wall movable about a first hinge between a collapsed position generally parallel to the floor and a use position generally perpendicular to the floor; a second wall movable about a second hinge between a collapsed position generally parallel to the floor and a use position generally perpendicular to the floor; and a latch integrally molded with the first wall for selectively connecting the first wall to the second wall while the first and second walls are in the use position, the latch configured to be selectively disconnected upon the application of force from outside the collapsible container by actuation of a latch member and wherein the latch is configured to be selectively disconnected by an application of an inwardly directed force on the second wall.
According to another aspect of the present invention there is provided a collapsible container comprising a floor; a first wall movable about a first hinge between a collapsed position generally parallel to the floor and a use position generally perpendicular to the floor; a second wall movable about a second hinge between a collapsed position generally parallel to the floor and a use position generally perpendicular to the floor; and a latch integrally molded with the first wall for selectively connecting the first wall to the second wall while the first and second walls are in the use position, the latch configured to be selectively disconnected upon the application of force from inside the collapsible container by actuation of a latch member and wherein the latch is configured to be selectively disconnected by an application of an inwardly directed force on the second wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A collapsible container 10 according to the present invention is illustrated in Figure 1. Container 10 is rectangular in shape and is generally symmetrical about each center line. Container 10 includes a base 12 and upstanding perpendicular opposing side walls 14 and opposing end walls 16. Base 12 includes a floor 18, a pair of first opposed base side portions 20 defining base side upper edges 22 along the sides of container 10, and a pair of second opposed base end Portions 24 defining base end upper edges 26 along the ends of container 10. Side walls 14 are connected to base 12 by hinges 28, while the end walls 16 are connected to base 12 via hinges 30. As is shown, the side walls 14and end walls 16 are collapsible by pivoting at hinges 28, 30 onto base 12. As shown in Figures 2 and 11, the crate can be collapsed inwardly for shipping or storage and can be quickly set up by pivoting walls 14, 16 about their respective hinges to the use position, generally perpendicular to floor 18. Side walls 14 include tabs 19 extending above the upper edge 21 of side walls 14 for providing an inter-engaging feature between stacked containers 10, as discussed further herein. Side walls 14 each include three areas 23 which are bowed outwardly, while end walls 16 each include one such relatively larger area 25. End walls 16 include a handle opening 31. In the present embodiments, the end walls 16 are first to collapse against floor 18 and by way of reference but not limitation may generally be referred to as end walls or second walls. Of course, the teachings of the latched herein may be application to either set of walls. Side walls 14 may be referred to as first walls.
Container 10 also includes latches 34 for attaching adjacent side and end walls at the corners 32. Because the operation of each of latch 34 is similar, the operation of latch 34 will be described with reference to Figures 3a, 3b, 4a, 4b, 5a, and 5b. Figure 2 illustrates container 10 with end walls 18 in the collapsed position for better illustration of latch 34. Figure 3a is an enlarged perspective view of the interior of corner 32, with the top of the container 10 cut away. Latch 34 is integrally molded with side walls 14, which is preferably molded of polypropylene via an injection molding process but of course can be formed of any type of plastic applicable for the desired use. As can be seen in Figures 3a and 3b, latch 34 includes a recess 36 within which a narrow, outboard portion 38 of the lateral edge of end wall 16 is received to attach end wall 16 to latch 34 and thus side wall 14.
The narrow portion 38 of side wall 14 helps define a recess 36 on the outside of end wall 16. Latch 34 includes an inner release surface 40 extending into the container that is generally an inclined plane on a portion 42 tapering inwardly into container 10. In the assembled position, inner release surface 40 is positioned inwardly of recess 36 and end wall 16. Surface 40 may be used to actuate the latch 34 and collapse the container, whether by user or automation.
Latch 34 further includes an outer release surface 44, which is the outer portion of latch arm 45. Surface 44 is positioned outwardly of recess 36 and outwardly of narrow portion 38 of side wall 14. The outer release surface 44 is generally positioned within recess 37 of the end wall 16, such that the outer release surface 44 can be accessed through the recess 37. An inner end of the latch 34 includes a slightly narrowed portion 46, which increases the flexibility of latch 34 and permits it to pivot and flex at narrowed portion 46. Figures 4a, 4b, 5a, and 5b illustrate the latch at various positions from fully latched to unlatched. In Figures 3a-3b, the end wall 16 is latched to side wall 14 by latch 34. The portion 38 of end wall 16 is securely received in the recess 36 of latch 34. In this manner, the side wall 14 and end wall 16 are maintained in a generally perpendicular assembled position. In the embodiment shown, the outer release surface 44 is completely contained and enveloped within the recess 37 and does not protrude out from the plane of end wall 16. Thus a user may collapse the container by actuating release surface 44.
Opposite inner release surface 40 and adjacent wall portion 38, is a surface 48 of latch 34 that is shown as slightly angled in order to promote an additional feature of latch 34 as a knock-down style latch. Thus, should a user desire to use the knock-down features of container 10, the user may provide a slight force to the outer surface (in the direction of the arrow of Figure 4a), thereby causing wall 16, and more particularly wall portion 38, to contact outer latch surface 48, and thereby causing wall 16 to slide along angled surface 48, allowing latch 34 to deflect out of the way in order for wall 16 to bypass the latch and collapse onto base 12.
These steps are shown in Figure 4a (end wall 16 contacts surface 48), Figure 4b (wall 16 deflects latch as it moves into collapsed position) and Figure 5a-5b (wall 16 clears latch 34 and approaches collapsed position.) The force necessary to operate the knock-down feature may vary based on the desired latch resistance. Note that while surface 48 be disposed at various angles, surface 48 is only slightly angled sufficient to allow it to be knocked down with the desired force.
As shown in Figures 1, 2 and 3a, side walls 14 include an integrally molded section 50 positioned outwardly of latch 34 for preventing excessive outward deflection of the latch 34. Side walls 14 and end walls 16 also include at least one set of interlocking tab members 52, 53 (see Figure 2), respectively, to increase the stability of the connection between side walls 14 and end walls 16 at corner 32 as well as enhance alignment therebetween. Three sets of interlocking members are illustrated herein: interlocking tab members 52, 54, 56 on side wall 14 interlock with corresponding interlocking tab members 53, 55, 57 on end wall 16. Note that such interlock members are inwardly offset from the outer surface of the adjacent walls 14, 16 as disclosed further herein.
When it is desired to return container 10 to the collapsed position, latch 34 is biased and flexed outwardly in the direction of post 50 by the application of force on either the outer release surface 44, the inner release surface 40, or the inwardly directed force on the end wall 16 via the knock-down feature. This causes latch 14 to flex and pivot at the narrowed portion 46 and releases the portion 38 of end wall 16 from the recess 36 of the latch. The provision of the outer release surface permits the actuation of the latch 34 from outside container 10, which is easier for a user. The inner release surface 40 facilitates operation by automated equipment.
The knock-down feature promoted by surface 48 allows for a quick means to collapse without manual contact with latch 34 itself. End wall 16 is then able to pivot downward to the collapsed position (after similarly actuating the latch at the opposite end of end wall 16). The opposing end wall is unlatched in a similar fashion and pivoted to the collapsed position, followed by the side walls 14.
For assembly of container 10 to the use position, side walls 14 are pivoted upward to the use position, generally perpendicular to the floor 18. End wall 16 is then pivoted upward, causing narrowed portion 38 of end wall 16 to contact the inner release surface 40, causing latch 34 to flex outwardly as in Figure 4b.
When the narrowed portion 38 of end wall 16 passes the inner latch release surface 40 and outer latch surface 48, latch 34 returns to its normal position with the narrowed portion 38 received in recess 36 of the latch 34, thus returning the container to the assembled position of Figure 1.
Figure 6a illustrates a side view of container 10, while Figure 6b illustrates an end view of container 10.
Figure 7 illustrates a bottom perspective view of container 10 and Figure 8 shows a bottom plan view thereof. As illustrated, this container does not include an drag rail offset from the periphery as is known in other containers, but instead has a generally parallel set of ribs 60 extending around the periphery of container extending from the lower surface of floor 18, and also includes two sets of parallel ribs 62, 64 extending widthwise across the lower floor surface. The peripheral set of ribs 60 defines therein a series of openings 66 for receiving side wall upper edge tabs 19 when two similar assembled containers 10, 10' are stacked together (as in Figures 9-10), thereby allowing for an inter-engaging feature therebetween. A
perspective view of two assembled containers 10, 10' is shown in Figure 9, while a cross sectional view showing the inter-engagement between tabs 19 and openings 66' of an upper container 10' is shown in Figure 10.
Moreover, as shown in Figure 11, when the walls 14, 16 are collapsed, it is noted that the upper edges 22 of the side base walls 20 have tabs 69 similar tabs 19.
Tabs 69 are preferably similarly sized and in vertical alignment with wall tabs 19, such that when the walls are collapsed and similar collapsed containers 10, 10' are stacked together as shown in Figure 12, tabs 69 are received in corresponding openings 66' of base 12', thereby aiding in interengagement between the two.
As shown in Figure 13, tabs 19 and 69 can also work together to promote interengagement between a stack having both assembled 10 and collapsed containers 10', 10". With reference to Figures 14a-14b, note that tabs 19, 69 are also designed to align with openings 70 between respective rib sets 60, 62, 64 for allowing similar collapsed containers to interengage during cross-stacking. See Figure 14 which illustrates a bottom of container 10 with the tabs 19' and 19" of lower containers 10 and 10' disposed in openings 70.
Figure 15 illustrates the offset feature of interlocking tab 52, 54, and 56 on side wall 14. For illustrative purposes only, tab 52 is used. As shown, tab 52 is offset from the edge of side wall 14. Thus when folded downwardly, the offset tab 52 does not interfere with base wall 24, but instead clears base wall 24 and sits inwardly thereof. In some containers, the tab may be flush with the surface of the wall, such that cutouts or recesses must be formed in the base to accommodate the interlock features. Such cutouts and recesses may tend to not be as rigid as possible.
Figure 16 is a partial inner perspective view of a container similar to Figure 1, but having a tab 103 (similar to tab 19 of Figure 1) on the end wall 116. Such tab 103 may serve to provide additional interengagement when similar containers are stacked together.
Figure 17 is a perspective view of a container similar to v 1, but having a base with a lower floor and pair of undulations 280 formed in the floor for a more efficient package height when collapsed. Figure 18 shows the container in the fully collapsed position. As shown in Figure 19, undulations 280 are actually at a height similar to floor 18 in Figure 1, while floor 218 is on a plane similar to rib sets 60, 62, 64 of Figures 7-8. Thus as shown in Figure 19, floor 218 defines a corresponding recessed area on the top surface of floor 218 on the inside of container 210 adjacent undulations 280, so that when walls 216 are collapsed, they are folded into the recessed areas in order to create a more efficient package height. Moreover, the undersides of undulations define a recess 270 for receiving tabs 219, 269 during cross-stacking similar to that shown in Figures 14a-14b.
While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. The scope of the claims should not be limited by the preferred embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole. There are many different configurations for collapsible containers and many variations in design, many of which would benefit from the present invention. All are considered to be within the scope of the present invention. For example, latches 34 could be on end walls 16 instead of side walls 14.
Modifications to latch 34 for different applications are also possible, while still retaining the benefits of the present invention.
