FIELD OF THE INVENTION
This invention relates to containers such as tote boxes made from foldable box blanks and having self-locking top rails. More particularly, this invention relates to label holders for use with such tote boxes.
BACKGROUND OF THE INVENTION
Containers which are returnable/reusable are useful for the transportation, storage, and display of goods in commerce. Such containers, commonly called tote boxes, must be of sufficiently rigid construction to enable safe and damage free transport and storage of goods contained therein. These tote boxes are frequently designed so as to be stacked or mounted in a nesting relation for convenient transportation or storage of the tote boxes. In order to be stackable, the upper edge of the container or tote box is typically reinforced with a top rail or rim member which is adapted to receive another tote box stacked thereupon. For example, applicant's U.S. Pat. No. 6,305,601, which is fully incorporated herein, discloses a unitary top rail adapted to fit over the tops of the box walls. In addition, applicant's U.S. Pat. Nos. 6,349,877, 6,460,724; and 6,547,127, each of which is fully incorporated herein, each disclose a top rail made up of several pieces including four corner pieces.
It is conventional to use a variety of materials for the construction of such tote boxes. Such materials typically consist of corrugated paperboard, corrugated plastic sheet, sheet metal and other such materials.
Typically, in order to identify the contents of a container such a tote box, a plastic label holder is taped, glued or otherwise secured to the outer surface of the container or box. The label holder has a thickness so that it projects outwardly from the generally planar outer surface of the tote box wall. When the tote box is moving down an assembly line or being transported, the label holder may catch or snag on items in an undesirable manner. For example, one tote box may catch on the label holder of an adjacent tote box and cause the label holder to tear off. Another possibility is that the tote box may turn over spilling the contents of the tote box when the projecting label holder attached to the tote box catches on something. In addition, the assembly line may have to be shut down, thereby reducing productivity and wasting time. Consequently, the present practice of attaching label holders directly to the container wall may add cost and manufacturing time to the manufacturing process in which the container is used thereby reducing efficiencies in the manufacturing process.
Accordingly, it is a primary objective of the present invention to provide a label holder insert for use with a container which does not project beyond the outer surface of the container walls.
Another objective of this invention has been to provide such an injection molded label recess holder for use with a box or container which may be quickly and easily inserted into existing boxes or containers.
SUMMARY OF THE INVENTION
The present invention is directed to an injection molded, recessed plastic insert adapted to be secured in an opening in a wall of a box or container. The insert is adapted to be located in the opening in a snap fit manner quickly and easily. The insert may be further secured in the opening with at least one rivot, double sided tape, or at least one sonic weld. The insert has a recess which is adapted to receive and hold a label holder or a label in order to identify the contents of the box or container.
The injection molded plastic label holder insert has a generally rectangular recess adapted to receive a label holder. The rectangular recess is defined by a rear portion and a wall extending forwardly from the rear portion around the perimeter of the rear portion. The wall includes a lower wall portion, an upper wall portion and a pair of side wall portions.
Extending downwardly from the front of the lower wall portion of the recess are a pair of spaced front tabs. The front surface of these tabs may contain the manufacturer's trademark or other identifying symbols, words or letters. Between the front tabs and spaced rearwardly from the front tabs a distance equal to the thickness of the tote box wall is a rear tab. The rear tab extends downwardly from the lower wall portion of the recess like the front tab. In one preferred embodiment of the present invention, the front and rear tabs are similarly sized. However, they may be different sizes without departing from the spirit of the present invention.
A pair of side tabs extend outwardly from the front edges of the side wall portions of said recess. These tabs are designed to abut the front surface of the box wall and help secure the label holder insert in place.
A top flange extends upwardly from the rear portion of the recess. The top flange may have a hole centrally located therethrough adapted to receive a fastener such as a rivet. The top flange provides a stop which abuts the inside surface of the box wall when the insert is seated or secured in place. The top flange of the insert may be rivoted, taped, or sonic welded to the box wall. Alternatively, the top flange of the insert may be pinched or trapped between the box wall and the top rail of the box in order to further secure the insert in the opening of the box wall.
In front of the top flange are a pair of spaced catches extending upwardly from the front of the upper wall portion of the recess. These catches are adapted to abut the front surface of the box wall after the insert is snap-locked in the opening of the box wall.
In practice, the box wall below the opening in the box wall is received between the front and rear tabs of the insert. The insert is then pushed forwardly from the inside of the box, causing the catches to push past the tote box wall and snap in place in front of the tote box wall above the wall opening. When the insertion is done, the box wall rests between the top flange of the insert which abuts the inside surface of the box wall and the catches which abut the outside surface of the box wall.
One advantage of the present invention is that a label holder may be quickly and easily put on a container such as a tote box without worrying about whether the label holder will catch on nearby exterior surfaces. The insert of the present invention provides a recessed area within a container where a customer may place labels or label holders that are recessed from the outside surface of the container, preventing the label or label holder from being removed or ripped off from surface-to-surface contact with containers, conveyors, etc. Another advantage of the present invention is that label holders may be changed more quickly and less expensively than is presently possible in competitive type tote boxes.
An alternative preferred embodiment of the present invention has a cover hinged to the insert to protect a label resting in the recess from the elements. The cover may be locked in place via a locking mechanism to prevent the cover from opening. The cover is preferably hinged to the lower wall portion of the recess, but may be hinged in alternative locations. In other embodiments, the cover may be removably secured to the insert rather than hinged.

DETAILED DESCRIPTION OF THE DRAWINGS
Referring to FIG. 1, there is illustrated an assembled tote box 10 according to the present invention. The tote box 10 is assembled from a uniform thickness box blank (not shown) which is die cut or otherwise pre-cut from, preferably, corrugated plastic sheet. However, the box blank and resulting box may be made from any other suitable material. In one preferred embodiment, the box blank is 5 millimeters thick and made from extruded corrugated plastic material. Depending upon the application, the box blank may be other thicknesses or materials as well.
As best illustrated in FIG. 1, the tote box 10 comprises a box 12 formed from the foldable box blank (not shown), a top rail 14 having an upwardly extending outer lip 16 which facilitates stacking multiple tote boxes, and four corner enhancers 18a-18d. The top rail 14 may be a unitary piece as shown or made of multiple pieces.
Referring to FIG. 1, the box 12 has a bottom 20, two end walls 22a and 22b, and two side walls 26a,26b. The end walls 22a, 22b each have an outside surface 24 and an inside surface 23. Similarly, each of the side walls 26a, 26b have an outside surface 28 and an inside surface 30. The end walls 22a, 22b may be the same length as the side walls 26a, 26b, resulting in a square box. Alternatively, the length of the end walls 22a, 22b may be different than the length of the side walls 26a, 26b, resulting in a rectangular box.
Oval shaped holes 32 are cut through the end walls 22a, 22b and may accommodate hand holds (not shown) which preferably are fabricated from plastic or aluminum but may be constructed of any material. Although the holes 32 are illustrated as being formed in the end walls 22a, 22b, they may alternatively be placed in the side walls 26a, 26b. 
As shown in FIG. 1, at least one of the tote box walls has injection molded label holder insert 34 of the present invention secured therein. Although FIG. 1 illustrates the injection molded label holder insert 34 located in end wall 26b, it may be located in any one or multiple tote box walls. Similarly, the injection molded label holder insert 34 may be used in any type or configuration of container other than tote boxes.
Referring to FIG. 2, the injection molded label holder insert 34 is preferably made of one piece of plastic material; however, it may be made of multiple pieces and may be made of any material. The label holder insert 34 comprises a generally rectangular recess 36 adapted to receive a label holder 38 or label. If a label holder is used, the label holder 38 is adapted to receive a label 40 in order to identify the contents of the tote box. The label holder 38 and label 40 are not intended to be a part of the present invention. The injection molded label holder insert 34 of the present invention may be used with any type of label holder. The recess 36 is defined by a generally planar rear portion 42, a lower wall portion 44, an upper wall portion 46 and a pair of side wall portions 48. Each of the wall portions 44, 46 and 48 extend forwardly from the rear portion 42 of the recess 36 around the periphery thereof. Each of the lower, upper and side wall portions 44, 46 and 48 have coplanar forward edges which define the front plane P1 of the insert. See FIG. 3.
As seen in FIG. 2, the insert 34 has a width W which is defined as the distance between the outer surfaces 49 of the side wall portions 48 of the recess 36. The insert 34 also has a height H which is defined as the distance between the outer surface 51 of the upper wall portion 46 and the outer surface 53 of the lower wall portion 44 of the recess 36.
Generally in the front plane P1 of the insert, a pair of spaced front tabs 50 extend downwardly from the lower wall portion 44 of the recess 36. Each of the front tabs 50 have an inside surface 52 adapted to abut the outer surface 28 of the tote box wall 26b and an outer surface 54 upon which indicia (not shown) may be printed or otherwise located.
As best seen in FIGS. 3 and 4, a pair of outer rear tabs 57 and a middle rear tab 56 therebetween extend downwardly from the rear portion 42 of the recess 36. Each rear tab 56, 57 has an inside surface 58 adapted to abut the inner surface 30 of the tote box wall 26b and an outer surface 60. Each outer surface 60 extends downwardly from the lower wall portion 44 of the recess 36. The outer rear tabs 57 and middle rear tab 56 each is spaced rearwardly of the front tabs 50 a distance equal to the thickness T of the tote box wall 26b, i.e. the linear distance between the inner and outer surfaces 30, 28 of the tote box wall 26b. 
The pair of outer rear tabs 57 extend downwardly from the lower wall portion 44 of the recess 36 outside of the middle rear tab 56. Like the middle rear tab 56, the outer rear tabs 57 are spaced rearwardly of the front tabs 50 a distance equal to the thickness T of the tote box wall 26b, i.e. the linear distance between the inner and outer surfaces 30, 28 of the tote box wall 26b. 
Another portion of the injection molded label holder insert 34 comprises a top flange 62 extending upwardly from the rear portion 42 of the recess 36. The top flange 62 extends the full width W of the insert 34, the distance between the outer surfaces 49 of the side wall portions 48 of the recess 36. As shown in FIG. 3, the top flange 62 has an inner surface 64 which is adapted to abut the inner surface 30 of the tote box wall 26b and an outer surface 66. The top flange 62 is generally coplanar with the rear tabs 56, 57 in a rear plane P2 of the insert 34. A rivet hole 68 is centrally located and passes through the top flange 62.
Spaced a distance equal to the thickness T of the tote box wall 26b in front of the top flange 62 are a pair of spaced catches 70. The catches 70 are located generally in the front plane P1 of the insert 34 and are adapted to abut the outer surface 28 of the tote box wall 26b when the insert 34 is snapped into place.
Lastly a pair of side tabs 72 extend outwardly from the front edge of the side walls 48 of the recess 36. These side tabs 72 are located generally in the front plane P1 of the insert 34 and are adapted to abut the outer surface 28 of the tote box wall 26b when the insert 34 is snapped into place.
The method of inserting the injection molded label holder insert 34 of the present invention into the opening of the tote box wall is best illustrated in FIG. 3. As shown in FIG. 3, the insert 34 is located on the inside of the tote box 10 and passed through an opening 75 in the tote box wall 26b. More particularly, the pair of spaced front tabs 50 extending downwardly from the lower wall portion 44 of the recess 36 are located in front of the tote box wall 26b such that said tote box wall is trapped between the rear tabs 56, 57 extending downwardly from the lower wall portion 44 of the recess 36 and the front tabs 50. In this position, the lower edge 77 of the opening 75 abuts the outer surface of the lower wall portion 44 of the recess 36. The side tabs 72 are then passed through the opening 75 in the tote box wall 26b. 
Once the insert 34 is properly seated, the side tabs 72 abut the outer surface 28 of the tote box wall 26b. The spaced catches 70 extending upwardly from the upper wall portion 46 of the recess 36 are then passed or snapped through the opening 75 in the tote box wall 26b such that the tote box wall 26b is trapped between the top flange 62 and the catches 70.
The last step in the process is securing the top flange 62 to the tote box wall 26b with double sided adhesive tape 78 as shown in FIG. 2, a rivet (not shown) or a sonic weld (not shown). As an alternative to any of these method the top flange 62 of the insert 34 may be trapped underneath the top rail 14 of the tote box in the manner illustrated in FIG. 4.
When the insert 34 is secured in place, the recess 36 is located generally inside the wall 26b of the tote box 10. As shown in FIG. 3, a label or label holder located in the recess 36 is prevented from being caught on passing objects using the insert 34 of this invention.
FIG. 5 illustrates an alternative preferred embodiment of the present invention. For the sake of simplicity, where possible, like numbers will be used for like parts, but the letter designation “a” will be used to describe this preferred embodiment.
In this preferred embodiment a cover 80 is hingedly secured to the recess 36a along a living hinge 81. More particularly, the cover 80 is hinged to the lower wall portion 44a of the recess 36a. The cover 80 is movable between an open position shown in FIG. 5 and a closed position (not shown). The cover 80 has a outer surface 82, an inner surface 84, an upper edge 86, a lower edge 88 and a pair of side edges 90. The cover 80 has a finger hole 92 which helps the operator open the cover 80 when the cover 80 is locked in a closed position covering a front opening 5 of the recess 36a. The finger hole 92 has an arcuate edge 94 which extends inwardly from the upper edge 86 of the cover 80. The finger hole 92 in the cover allows an operator to open the cover 80 when desired by inserting a finger therein and pulling the cover 80 outwardly with sufficient force to overcome a locking mechanism 100 which will be described in detail below.
Similarly, the cover 80 has a second finger hole 96 along the bottom of the cover 80. This finger hole 96 has an arcuate edge 98 which extends inwardly from the lower edge 88 of the cover 80. This finger hole 96 is located and sized to mate or correspond with an opening 7 in the lower wall portion 44a of the recess 36a. The opening 96 in the cover in conjunction with the opening 7 allows an operator to open the cover 80 when desired by inserting a finger therein and pulling the cover outwardly with sufficient force to overcome a locking mechanism 100.
The locking mechanism 100 functions to lock the cover 80 in a closed position. The locking mechanism 100 comprises two catches 102, one on each side of the cover 80. Each catch 102 extends outwardly from the inner surface 84 of the cover 80 immediately inside a generally rectangular blocking member 104. In alternate embodiments, the catches may extend outwardly directly from the blocking members 104. Each blocking member 104 is sized to abut the rear portion 42a of the recess 36a immediately inside the side wall portions 48a of the recess 36a when the cover 80 is in its closed position. The blocking members 104 prevent the cover 80 from closing too much, ensuring that the outer surface 82 of the cover 80 is generally co-planar with the side tabs 72a of the recess 34a and generally parallel the front plane P1 (see FIG. 3).
Each catch 102 is adapted to be received inside an opening 106 in the rear portion 42a of the recess 36a. As shown in FIGS. 5 and 6, each catch 102 has a lip 108 adapted to abut the rear portion 42a of the recess 36a and lock the cover 80 in its closed position. When locked in its closed position, the cover 80 may protect a label 40a located in the recess 36a from the elements. To move the cover 80 into its open position, an operator applies sufficient force via one of the finger holes 92, 96 to release the catch 102 from engagement with the rear portion 42a of the recess 36a. The cover 80 may then pivot outwardly along the hinge 81 to provide the operator with access to the recess 36a and any labels 40a positioned therein.
The cover 80 is preferably made of a clear plastic material to enable one to easily read the label 40a located in the recess 36a. However, the cover 80 may be made of any desired material.
FIG. 7 illustrates a further alternative embodiment of the present invention. Because the embodiment shown in FIG. 7 is similar to the embodiment shown in FIG. 5, like numbers will be used to refer to like elements but with a letter “b” designation.
Rather than being hingedly secured to the recess 36b, the cover 80b in the preferred embodiment of FIG. 7 is removably secured to the label holder insert 34b. In other words, the cover 80b is movable between an open position (FIG. 7) in which the cover 80b is disengaged from the label holder insert 34b and a closed position (not shown) in which the cover 80b engages the label holder insert 34b. 
The cover 80b is locked in the closed position by a locking mechanism 200, which includes the catches 102b and operates under the same principles that were discussed with reference to the locking mechanism 100 shown in FIGS. 5 and 6. The locking mechanism 200 in this embodiment, however, further comprises one or more additional catches 202 positioned near the lower edge 88b of the cover 80b. Like the catches 102b, each catch 202 extends outwardly from a generally rectangular blocking member 204 positioned on the inner surface 84b of the cover 80b. Each blocking member 204 is sized to abut the rear portion 42b of the recess 36b immediately inside the lower wall portion 44b of the recess 36b when the cover 80b is in its closed position. The blocking members 104b and 204 prevent the cover 80b from closing too much, ensuring that the outer surface 82b of the cover 80b is generally co-planar with the side tabs 72b and front tabs 50b. Although only one type of locking mechanism 200 is illustrated herein, any other suitable locking mechanism may be used in accordance with the present invention to removably secure a cover over the recess of the label holder insert to protect a label.
As shown in FIG. 7, each catch 202 is adapted to be received inside an opening 206 in the rear portion 42b of the recess 36b when the cover is in the closed position. The catches 202 function in the same manner as the catches 102b that were discussed with reference to FIG. 6. Thus, each catch 202 has a lip 208 adapted to abut the rear portion 42b of the recess 36b to partially lock the cover 80b in its closed position. The cover 80b is fully locked in its closed position when both the catches 102b and 202 are inserted through the respective openings 106b and 206. An operator can remove the cover 80b by applying sufficient force via one or both of the finger holes 92b, 96b to release the catches 102b and 202 from engagement with the rear portion 42b of the recess 36b. 
When locked in its closed position, the cover 80b may protect a label 40b located in the recess 36b from the elements. The cover may also prevent the label 40b from being ripped, torn, or damaged by surface-to-surface contact when the container moved down an assembly line or transported. The removable nature of the cover 80b allows labels to be changed quickly and inexpensively, thereby increasing productivity and facilitating use of the containers for a variety of purposes.
While we have described several preferred embodiments of the present invention, persons skilled in the art will appreciate changes and modifications which may be made without departing from the spirit of the invention. For example, although one configuration of tote box 14 is illustrated and described, the present invention may be used with other configurations of boxes. Therefore, we intend to be limited only by the scope of the following claims and equivalents thereof:
