Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a container, and more particularly, to an insulated container having a lid prop and/or a latch for the lid.
2. Discussion of Related Art
It is known in the art to provide insulated containers for shipping goods in a controlled thermal environment. Such a container is frequently a substantially parallelepiped structure made from rotationally molded, insulated walls. In one such structure, each of the dimensions is approximately between three and four feet, thus providing a structure having a cubic volume of between about twenty-seven cubic feet and sixty-four cubic feet. In such a container, the bottom, four legs, and four walls are typically either formed in one piece or permanently connected to form a unitary structure. The lid or top of the container is a separate piece and either fits securely against the top of the walls, or is hingeably connected to the walls. See, e.g., U.S. patent application Ser. No. 10/778,210, the entire contents of which is incorporated herein by reference.
One known use for such a described container is the shipping and/or storage of a variety of temperature controlled products. When using such a container, particularly a container having a dimension of at least four feet in height, it is not difficult to remove products from the container when the container is full and the products are near the top of the container. However, as the container is emptied, the user must lean over into the container to remove the products from the bottom of the container. Having to lean over to remove products from the bottom of the container places the user in an awkward position. As the user's hands are generally used to grasp the item being placed into or removed from the container, should the lid accidentally close, the user will be unable to use his or her hands to defend against a closing lid without releasing or dropping and possibly damaging the products. The alternative to releasing and dropping the gripped products is to accept the force from the lid on the upper part of the user's torso or head area.

OBJECTS AND SUMMARY

Accordingly, it is an object of one aspect of the present invention to provide an insulated container which includes a lid prop which is convenient to use and cheap to install and manufacture and lessens the chances of accidental closure of the lid.
It is another object of another aspect of the present invention to provide an insulated container with a latch for securing the lid in a closed position.
According to one embodiment of the invention, a container includes a body defining a storage space having an opening; a lid that is pivotally mounted to the body, the lid having a closed position wherein the lid prevents access to the storage space, and the lid having an open position wherein the lid provides access to the storage space; a recess arranged in a wall of the body; a plate partially covering the recess, the plate including a slot extending longitudinally through the plate; a lid prop comprising a longitudinally extending member, the lid prop being arranged so that a first end of the lid prop is pivotally engaged to the lid and a second end of the lid prop is engaged in the slot in the plate; wherein when the lid is in the open position the prop may be positioned against an end of the slot thereby preventing the lid from opening beyond a certain limit.
According to another embodiment of the invention, a container includes a base having a bottom and four walls connected to the bottom defining a storage space having an opening at the top to provide a user access to the storage space, the opening being defined by a rim. A first recess having a first depth is formed in the rim and a second recess having a second depth less than the first depth is formed in the rim adjacent the first recess, the first and second recesses define a step between the two recesses. A lid is pivotally mounted to one of the walls and is adapted to fit onto the rim to close at least a portion of the opening. A prop has a first end and a second end and is arranged so that the first end is pivotally secured to the lid and the second end is capable of fitting slidably in the first recess and the second recess and to abut against the step between the first and the second recesses when the lid is in the open position, thereby preventing the lid from closing. The prop is adapted to fit substantially within the second recess when the lid is in the closed position.
According to another embodiment of the invention, a container comprises a body defining a storage space having an opening, a lid that is pivotally mounted to the body and has a closed position wherein the lid prevents access to the storage space and an open position wherein the lid provides access to the storage space, a recess, and a stopper. A lid prop comprises a longitudinally extending member and is arranged so that when the lid is in the closed position the lid prop may be positioned substantially within the recessed area, and when the lid is in the open position the lid prop may be positioned against the stopper thereby discouraging the lid from closing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1-16 illustrate preferred embodiments of containers according to the present invention. In the illustrated preferred embodiments, the container is insulated and made from rotationally molded polyethylene plastic, with foamed urethane in the center of the walls to enhance the insulation thereof. However, the present invention is not limited to such construction, and insulated containers according to the present invention could be made from any suitable construction.
A first preferred embodiment is illustrated in FIGS. 1-7.
The container 100 includes a bottom 120 and four walls 114, 115, 116, 118 having a substantially continuous rim 130. The rim includes a flange 131 extending upward therefrom designed to accommodate a lid 123. The lid 123 fits against the rim 130 and flange 131 defined by the four walls 114, 115, 116, 118.
Preferably, the container 100 has four legs secured to the bottom 120 thereof, three of which (134, 136, 137) are visible in FIG. 1. The lid 123 includes four recesses 150 which are designed and arranged to accommodate the pads 134, 136, 137 of a similar container so that the similar container can be stacked on top of the container 100.
The lid 123 includes a flange 132 extending downwardly therefrom which is designed to accommodate the rim 130 and the flange 131. Preferably, the lid flange 132 fits around the outside of the wall flange 131 when the lid is in the closed position, but alternatively, wall flange 131 can be on the outer edge of the rim 130 and the lid flange 132 can fit within the inside of the wall flange 131. The walls 114, 115, 116, 118 and the lid 123 are designed such that the rim 130 and the lid flange 132 fit together in a matting configuration to enhance the insulation and stability of the container 100.
As best seen in FIGS. 3A and 3B, a recessed portion 121 is formed in the wall 114, behind a plate 111, in order to provide an operating space for the a lid prop 160.
A first end 162 of the lid prop 160 is preferably located through a hole 125 in the lid 123 and is secured within the hole 125 with a push cap that is attached to the first end 162 of the lid prop 160. Preferably, the hole 125 is located in the lid flange 132 which extends from the peripheral edge of the lid 123.
A second end 166 of the lid prop 160 is slidably secured within the slot 112 of the plate 111 to enable movement of the second end 166 from one end of the slot 112 to the other end.
The plate 111 includes a slot extension 115. Depending upon the particular desires of a customer, the plate 111 can be mounted in the position shown in FIG. 3A, wherein the extension 115 is not utilized, or it can be mounted in the position shown in FIG. 3B, wherein the extension 115 is at the rear end of the container. When the extension 115 is in the forward position, the second end 166 of the lid prop does not reach the extension 115. See FIG. 4. However, when the extension 115 is mounted in the position illustrated in FIG. 3B, the extension 1 1 5 can engage the second end 166 of the prop 160 thus locking the lid 123 in the open position. The lid 123 can be easily unlocked merely by lifting the lid prop 160 with one's hand prior to closing the container 100. In either arrangement, the lid prop 160 can slide freely through the slot 112
FIG. 5 illustrates the preferred embodiment in the process of opening the lid 123, wherein the second end 166 of the lid prop is moving through the slot 112.
As can be seen in FIG. 6, when the lid 123 is in the closed position, the lid prop 160 is substantially hidden from view, except for the ends 162, 166.
Another feature of the present invention illustrated in FIG. 7 is that the lid 123 can have a primary step 134 which engages with and seals on the top of the walls of the container 100. In addition, the lid includes a recessed area 135, wherein a gasket can be inserted for improving the seal of the lid 123 against the walls of the container 100.
A second preferred embodiment of the container is illustrated in FIGS. 8-16. The second embodiment is substantially the same as the first embodiment, except as described herein and in the drawings. The second embodiment includes a container 10 with a lid prop 60. A first end 62 of the lid prop 60 is preferably located through a hole 25 in the lid 23 and is secured within the hole 25 with a washer 64 and a cotter pin 63 that is attached to the first end 62 of the lid prop 60. Preferably, the hole 25 is located in the lid flange 32 which extends from the peripheral edge of the lid 23.
A first recess 70 is formed in the wall 14, thereby forming a step 74. See FIGS. 11 and 12. Preferably, a second recess 72 is also formed in the wall 14 and both preferably are located in the rim 30. The first recess 70 has a first depth that is greater than the depth of the second recess 72. Preferably the step 74 extends vertically as shown in FIG. 1. In the open position, the lid 23 and the lid prop 60 can be positioned so that the second end 66 of the prop 60 abuts the vertical step 74, thereby preventing the lid 23 from closing.
As seen in FIGS. 11,12 and 13, in the closed position, the lid 23 fits against the rim 30 thereby covering the opening 17 of the container 10, and the prop 60 is positioned inside the second recess 72. As seen in FIG. 12, the prop 60 fits slidingly within the first recess 72 thereby allowing movement of the lid 23.
It should be appreciated that, in an alternative embodiment, the first recess 70 could be formed in the wall 14 (as illustrated), and the second recess could be formed in the lid flange 32, or that the container could function with only the first recess 70.
In the embodiment illustrated in FIG. 11, a clip 68 is provided to engage the second end 66 of the lid prop 60 when the lid 23 is in the open position. The clip 68 is positioned such that there is sufficient space between the clip 68 and the step 74 to enable the second end 66 of the lid prop 60 to be released from the clip 68 by manually pulling the prop 60 out from under the clip 68. The clip 68 functions so as to limit the extent to which the lid 23 can be opened, i.e., to prevent the lid 23 from being opened any further than illustrated in FIGS. 9 and 11 (about 95 degrees).
As seen in FIGS. 8, 9, 14 and 16, a preferred embodiment of the container includes a latching mechanism. An elastic cord 80 has a first end 86 which is attached to the front wall 12 of the container 10. A clip 81 is used to form a loop 83 at the first end 86 of the cord 80, and the loop is held to the front wall by a permanent clasp 11. The cord 80 may be reinforced in the region held by the clasp 11 to minimize wear. A spherical object 82 is attached to a second end 84 of the elastic 80, as best illustrated in FIG. 16A. To latch the lid 23 in the closed position, the elastic cord 80 is stretched and located inside a groove 13 in the so that the object 82 is retained in a socket 14 at the end of the groove 13 farthest from the clasp 11. As the smallest diameter of the spherical object 82 is larger than the largest diameter of the groove 13, the spherical object 82 cannot fit through the groove 13 and the elastic force produced by the stretched elastic cord 80 maintains the lid 23 in the closed position.
It should be appreciated that in alternate embodiments the groove 13 can be formed in the body of the container and the elastic 80 can be held to the lid by a clasp or other device.
When filling the container 10, the lid 23 is opened. In one embodiment, the container 10 is well suited for storing and shipping a variety of temperature controlled products. After the container 10 is filled, the lid 23 can be closed and latched as described herein and the container is ready for shipment.
When unloading the contents of the container 10, the lid 23 is moved to an open position. In the open position, the second end 66 of the lid prop 60 slides within the second recess 72 and passes the vertical step 74 into the first recess 70. When the lid 23 is in the opened position, the second end of the prop 66 abuts against the vertical step 74 thereby preventing movement of the lid 23 toward the closed position. In a preferred embodiment of the container, hinges 52 are formed so as to prevent the lid 23 from opening more than approximately 95 degrees with respect to a plane defined by the opening 17.
In the illustrated embodiments, the lid prop 60 is pivotally mounted to the lid 23 and the rim 30 has the recesses 70, 72. However, in an alternative embodiment, the lid prop 60 can be pivotally mounted to the rim 30 and recesses can be located in the lid 23.
In both embodiments, the lid prop can be arranged so that it neither protrudes into the interior of the container nor extends outwardly from the container walls. Such a design reduces the likelihood of damage to the lid prop and minimizes the influence of outside temperatures on the inside of the container.
Although only preferred embodiments are specifically illustrated and described herein, it will be appreciated that many modifications and variations of the present invention are possible in light of the above teachings and within the purview of the appended claims without departing from the spirit and intended scope of the invention.
