The following description is presented to enable any person skilled in the art to make and use the invention. For the purposes of explanation, specific nomenclature is set forth to provide a plural understanding of the present invention. While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.
A container, shown as a box, comprising handles according to a first embodiment of the present disclosure is illustrated in
The top side 11 comprises a first top panel 28 and a second top panel 32. As shown in
The first top panel 28 comprises a first top handle 36. The second top panel 32 comprises a second top handle 38. Since the first handle and the second handle are identical, as shown in
The handle 36 comprises a first base block portion 46, a second base block portion 48, and a handle portion 44. The handle portion extends from each of the first and second base block portions.
The handle comprises two bottom edges 50, 64. The handles are attached to the panel 28 and bendable relative to the rest of the panel 28 at the bottom edges 50, 64. Perpendicular to the bottom edge 50 are a first side edge 46 and a second side edge 54. Perpendicular to bottom edge 64 is a third side edge 66 and a forth side edge 68. Opposite the bottom edge 50 is an optional bend line 51. Opposite bottom edge 64 is an optional bend line 65. The first base block 46 is defined by bottom edge 50, sides 52, 54, and bend line 51. The second base block 48 is defined by the bottom edge 64, sides 66, 68, and bend line 65. The bottom edges 50, 64 may be bend locations without any predetermined or predefined scoring or perforation.
The handle portion comprises a first outer curved side 56, a second outer curved side 70, and an end portion 72 connecting the first outer curved side in the second outer curved side. The handle portion 44 further comprises a first inner side portion 58, a second inner portion 60, third inner side portion 62. The first inner sidewall portion 58 is aligned with and connected to the second side edge 54. The third inner side portion 62 is connected and aligned with the third side edge 66. In some embodiments, the second inner portion 60 is curved as shown in
The handles may be moved to the raised position from the stored position by pressing with a user's hand or fingers the lower area 71a of the panel adjacent portion 60 of the handle. Then sliding one or more fingers, as shown in
When the handles is moved to the raised position, the handle 36 is raised from panel 28 so that a first handle recess 80 is left in the panel 28. The handle 38 is raised from the panel 32 so that a second handle recess 82 is left in the panel 32. The handles 36, 38 are pivoted upwards towards each other by the user. Once they are raised sufficiently high so an open area 84 underneath each is available, a user can place user's hand in the open area 84 and grasp both of the handles together from the bottom of each handle, for example at the second inner portion 60. The box can be carried by a user's hand grasping one or both handles and lifting the handles and therefore the box. The handle 36 pivots at bottom edges 50, 64 relative to the remainder of the panel 28. Handle 38 pivots in the same manner with respect to panel 32.
In some embodiments, the handles 36, 38 can each bend at the bend lines 51, 65 (not labeled for handle 38), so that the handle portion 44 of each handle 36, 38 are aligned next to each other. In some embodiments, the handle portion 44 of each handle 36, 38 are substantially parallel or substantially vertical in the raised position. The base blocks 46, 48 of handle 36 can be angled towards the base blocks of handle 38 as shown in
When the handles are in the deployed position, the box is easily carried in one hand at the adjacent handles 36, 38.
When the handles 36, 38 are no longer needed in the raised position, the user can pivot each handle down so that it is received in the recess 80, 82. When moving from the raised to the stored position, the handles are pivoted about the bottom edge 50, 64.
The top side 111 comprises a first top panel 130 and a second top panel 134. As shown in
The third top panel 128 comprises a first top handle 136 and a second top handle 138. The third top panel 128 comprises a front tab 140. The first top panel 130 comprises a first handle slot 142. The second top panel 134 comprises a second handle slot 143. The fourth top panel 132 comprises a tab slot 139 at or about the fold line 141 between panel 132 and panel 112.
Handle 136 comprises a first base block portion 146, a second base block portion 148, and a handle portion 144. The handle portion 144 extends from each of the first and second base block portions. The handle portion comprises a curved outer edge 156 and a curved inner edge 160 similar to the second inner portion 60. Adjacent a center of the curved outer edge is a finger recess 152 configured to receive a user's finger so that the user can pivot the handle 136 upward and away from the panel 128. Adjacent the handle opposite the finger recess is a bottom side opening 154. The bottom side opening can be used in the same manner as the finger recess to enable the user to grab the handle when it is in the stored position. In some embodiments, there is no bottom side opening 154. Handle 138 is identical to handle 136, but is rotated 180 degrees from handle 136 and is spaced apart from handle 136 as shown in
Next the user lifts each handle 136, 138 into a raised position. The handles pivot at bend locations 150, 164, 151, 165 in the directions C and D, respectively. The user may use the finger recesses 152, 153 to grab each handle and move it from the stored position to the raised position. In the raised position, the handles are transverse to the panel 128. In some embodiments or uses, in the raised position, the handles may be vertical or substantially vertical. In some embodiments or uses, in the raised position, the handles are at a right angle to the panel 128.
Next, panels 130, 134 are folded down in the directions E and F of
When the panels 130, 134 are folded down to the closed position and the handles extend through the slots 130, 134, the handles 136, 138 can have a range of motion toward (in directions C and D, respectively, of
Tape or another adhesive may be applied to join panels 130, 134 at or about the seam 167. Tape or adhesive may be applied over tab 140 and down at least a portion of the panel 112. It may also be applied down at least a portion of the panel 116. In this way, panels 130, 134 are joined together and are joined by the tape or adhesive to panels 112 and 116.
To open the box 100, any tape or adhesive between panels 130, 134, 112, and 116 can be removed, cut, or released. The panels 130 and 134 are raised. In the process of being raised the handles are withdrawn from the slots 142, 143. Then the tab 140 is removed from the tab slot 139 and the panel 128 is raised. The handles can be folded to the stored position before or after panel 128 is raised. In some embodiments, when in the stored position, the handles are embedded in, or co-planar, or substantially co-planer with the panel 128 before or after the panel 128 is raised. Then, panel 132 is raised. Then all the panels 130, 128, 134, 132 are in a vertical or other raised position and the interior cargo area of the box 100 is accessible via an open top.
When the panels 230, 234 are folded down, in some embodiments, the handles 236, 238 need not be in the raised position. This is because the openings 242, 243 are large enough to allow the handles to move between the raised and lowered positions of the handles while the panels 230, 234 are folded down over panel 228.
While the drawings show that the boxes 10, 100, 200 each comprise two handles, in some embodiments, the top of each box has only one handle. In some embodiments, while the top of the box may comprises two handles, the user might only use one of the two handles to lift the box.
The handles may be formed in the top panel(s) of the box by cutting the outline shape of the handles in the corresponding panel(s) and leaving a bottom connecting portion uncut, such as at 50, 64, for a pivoting attachment of the handle(s) to the corresponding panel(s). Therefore, the handles may comprise the same material as the attached panel and/or the remaining portions of the box.
The handles may be cut into the top panel(s) at the same time as the entire container, or a portion of the container is being cut.
The container(s) 10, 100, 200 may be made by taking sheet(s) of material and feeding it into a machine having a roller die cutter. The sheet material is cut where the dies on the roller meet the material. The sheet may leave the roller die cutter having the perimeter, such as shown in
A method of manufacturing a container is provided. A plurality of cutting dies are mounted to a roller. Optionally one or more scoring elements are also mounted to the roller. The cutting dies and scoring elements are mounted to and positioned on the roller so that when the roller rolls over a sheet(s) of material, the dies will cut the sheet(s) and the scoring elements will score the sheets in predefined locations. When corrugated fiberboard is used, a sheet of corrugated fiberboard is feed toward the roller. The sheet is supported by a conveyor or a stationary lower support surface. The roller rolls over the sheet, or the sheet rolls under the roller, and the dies cut the sheet in the locations where the dies meet the sheet. The scoring elements score the sheet in the places where the scoring elements meet the sheet. When the sheet is away from the roller, the sheet will have the perimeter desired and set on the roller, such as the perimeter of the containers shown in
Another method of manufacturing a container using a flatbed die cutter is provided. A plurality of cutting dies are mounted to a die mount. Optionally one or more scoring elements are also mounted to the die mount. The cutting dies and scoring elements are mounted to and positioned on the die mount so that when the die mount is lowered onto a sheet(s) of material, the dies will cut the sheet(s) and the scoring elements will score the sheets in predefined locations. When corrugated fiberboard is used, a sheet of corrugated fiberboard is placed on a support, such as a flat support. The die mount is lowered over the sheet and the dies cut the sheet in the locations where the dies meet the sheet. The scoring elements score the sheet in the places where the scoring elements meet the sheet. Then the die mount is lifted from the sheet or the sheet is lowered from the die mount. Then the resulting sheet will have the perimeter desired and as set on the die mount, such as the perimeter of the containers shown in
A further method of manufacturing a container is provided. A sheet is placed on a cutting table. A milling device, with a rotating milling bit is mounted over the cutting table. The milling device is mounted on a moving mechanism that can move the milling device in at least the lateral and longitudinal directions relative to the sheet on the cutting table. The moving mechanism is controlled by a controller or a computer. The depth of the milling device/milling bit may also be controlled by the controller or computer. A design, such as the design of the container shown herein, may be loaded into the controller or computer. Then the computer causes the moving mechanism to move the milling device relative to the sheet/cutting table. The computer will cause the milling device or milling bit to move downward to engage the sheet, then it will cause the moving mechanism to move the milling device to cause cuts and/or scores to be made in or on the sheet. Then the resulting sheet will have the perimeter desired and set in the controller or computer, such as the perimeter of the containers shown in
While box shapes are shown in the drawings, it will be appreciated that the handles can be implemented in a top side panel or surface of containers of other shapes, such as containers having more or fewer sides than the boxes shown, or containers having angled sides, or on cylindrical containers. The boxes/containers and portions thereof may comprise any desirable dimensions and may be sized to suit a given application. In some embodiments, the boxes/containers comprise a square shape or a rectangle shape.
In some embodiments, the container/box 10, 100, 200 is made out of corrugated fiberboard, containerboard, paperboard, cardboard, chipboard, or plastic. In some applications, corrugated fiberboard comprises a fluted corrugated sheet and one or two flat linerboards. In some applications, the corrugated sheet and the linerboards are made of a containerboard, which may be a paperboard material. In some embodiments the containerboard comprises a thickness of more than 0.01 inches. An exemplary fragmentary cross-section of one type of corrugated fiberboard is shown in
