Two-panel bag with a tie handle

Abstract

A two-panel bag constructed from first and second panels that each has the same shape and size. The panels are connected together and a top edge is open for accessing the interior space. The top edge of the panels form handles that can be tied together to close the interior space. The two panels have a laterally inverted shape relative to a centerline. The top edge of each panel further includes two identical sections that each has a vertically-and-rotationally inverted shape. The shape of the panels facilitates manufacturing as the panels can be cut from a flat sheet with limited or no wasted material.

DETAILED DESCRIPTION

(11) The present application is directed to a bag that is constructed from first and second panels. Each of the two panels has the same shape and size. The panels are connected together along a section of outer edges to form an interior space. A top edge of the bag is open for accessing the interior space. The top edge of the panels include handles that can be tied together to close the interior space. The two panels further have a laterally inverted shape relative to a centerline. The top edge of each panel further includes two identical segments that each has a vertically-and-rotationally inverted shape. The shape of the panels facilitates manufacturing as the panels are formed from a flat sheet with limited or no wasted material.

(12) In one example, the bag 10 is used for washing laundry. Laundry items are inserted through the opening 11 and into the interior space 12. The handle sections 21 are tied together to maintain the items in the interior space 12. The tied bag 10 is then placed into a washing machine for washing and subsequently into a drier for drying the objects. Once complete, the handle sections 21 are untied and the clean clothes are removed from the interior space 12.

(13) FIG. 1 illustrates a bag 10 that is formed by two panels 20. Each of the panels 20 includes a handle section 21 and a body section 22. The panels 20 have the same shape and size. The two panels 20 are positioned in an overlapping configuration and are connected together with seams 13 that extend along edges of the body sections 22. An opening 11 is formed between the handle sections 21 and leads into an interior space 12 formed between the body sections 22.

(14) FIG. 2 illustrates a panel 20 that includes the handle section 21 and the body section 22. The panel 20 includes a top edge 30 along the handle section 21. The panel 20 also includes lateral edges 31, 32 and bottom edge 33 that extend along the body section 22. The panel 20 includes a centerline C/L that extends through the top edge 30 and the bottom edge 33. Each of the lateral edges 31, 32 and bottom edge 33 are straight. The lateral edges 31, 32 are perpendicular to the bottom edge 33. The lateral edges 31, 32 are perpendicular to the section of the top edges 30 at the corners 50.

(15) The body section 22 includes a width W. This width W is constant along the body section 22 between the upper and lower corners 50, 51. The handle section 21 extends outward from the body section 22 away from the bottom edge 33. The handle section 21 includes a length L1 measured between the top edge 30 at the centerline C/L and a straight line Q that extends between the upper corners 50. The body section 22 includes a length L2 that extends between the line Q and the bottom edge 33. The total length L of the bag 10 is the combination of the lengths L1, L2 of the two sections 21, 22. The length L1 is sized to tie the handle sections 21 together to close the interior space 12. In one example, the length L1 is about 20% of the entire length L of the bag 10. This percentage provides adequate length to tie the handle sections 21 together and provides for the interior space 12 to have an adequate size to hold objects.

(16) As illustrated in FIG. 3, the shape of the panel 20 is mirrored along the centerline C/L. A first lateral section 41 positioned on a first edge of the centerline C/L has the same shape and size as a second lateral section 42 positioned on a second edge of the centerline C/L. That is, the two lateral sections 41, 42 are laterally inverted about the centerline C/L. Common points along each lateral section 41, 42 are positioned an equal distance away from the centerline C/L. A first point A on the top edge 30 of the first lateral section 41 is positioned an equal distance from the centerline C/L as a corresponding first point A′ on the top edge 30 of the second lateral section 42. A second point B is likewise positioned an equal distance b from the centerline C/L as corresponding point B′. A third point C is positioned an equal distance c from the centerline C/L as corresponding point C′.

(17) The top edge 30 is divided by the centerline C/L into edge sections 30a, 30b. The two edge sections 30a, 30b are mirror images as they are laterally-inverted about the centerline C/L as each includes the same shape and size.

(18) Each of the edge sections 30a, 30b includes a shape that is vertically-and-rotationally-inverted about a midline M. This aspect is illustrated in FIG. 4 that illustrates the edge section 30b that extends between point 35 (which is the intersection of the top edge 30 and the centerline C/L) and the corner 50 (the intersection of the top edge 30 and lateral edge 32). The edge section 30b is divided by a midline M that is positioned along the edge 30b half-way between point 35 and point 50. A first segment 38 is positioned between the point 35 and the midline M. The second segment 39 is positioned between the midline M and the point 50. The first and second segments 38, 39 are inverted and rotated 180° relative to each other about the midline M. The first segment 38 has a concave shape and the second segment 39 has a convex shape as illustrated in the orientation shown in FIG. 4.

(19) FIG. 5 illustrates the edge section 30a with the vertically-and-rotationally inverted shape about the midline M. The first segment 38 extends between the point 35 and the midline M and the second segment 39 extends between the midline M and the point 50. Segment 38 has a concave shape and segment 39 has a convex shape as illustrated in the orientation of FIG. 5.

(20) The shape of the panel 20 facilitates manufacturing by reducing wasted material when the panels 20 are formed from an enlarged sheet 100. FIG. 6 illustrates an enlarged sheet 100 from which the panels 20 are formed. The sheet 100 includes a substantially rectangular shape with a leading edge 101, trailing edge 102, and outer edges 103, 104. The leading and trailing edges 101, 102 are parallel, the outer edges 103, 104 are parallel, and the leading and trailing edges 101, 102 are both perpendicular to the outer edges 103, 104. A width X of the sheet 100 is measured between the outer edges 103, 104. A length Y is measured between the leading and trailing edges 101, 102.

(21) The width X of the sheet 100 is sized to form two rows 105, 106 of panels 20. The panels 20 are aligned on the sheet 100 with the bottom edges 33 formed by the outer edges 103, 104. The handle sections 21 are positioned towards the center of the sheet 100. The panels 20 are offset along the length Y with the handle sections 21 on one row 105 of the sheet 100 interleaved with the handle sections 21 of the panels 20 on the second row 106 of the sheet 100. The shape of the top edge 30 of the panels 20 provides for the opposing panels 20 to nest together. The edge sections 30a, 30b of panels 20 in each of the rows 105, 106 is shared with edge sections 30a, 30b of opposing panels 20 in rows 105, 106.

(22) The nested positioning and the complementary shapes of the panels 20 prevent wasted material between the panels 20. In the example of FIG. 6, just two sections of wasted material are located on the sheet 100. A first section 109a is positioned at the leading edge 101 along row 106. A second section 109b is positioned at the trailing edge 102 along row 105. In one example, each of the sections 109a, 109b is substantially one-half of a panel 20.

(23) FIG. 7 illustrates a method of manufacturing a two-panel bag 10. The locations of the panels 20 are initially laid-out on the sheet 100 (block 200). The lay-out minimizes the amount of wasted material. The bottom edges 33 of the panels 20 are aligned on the outer edges 103, 104 of the sheet 100. The handle sections 21 are aligned towards a middle of the sheet 100.

(24) After the panels 20 are aligned on the sheet 100, the panels 20 are removed from the sheet 100 (block 202). In one example, this includes cutting the panels 20 from the sheet 100. The shape of the top edge 30 of the handle sections 21 complement each other and can be simultaneously formed with a single cut. Likewise, the lateral edges 31, 32 are shared between adjacent panels 20 and formed with a single cut. The layout of the panels 20 on the sheet 100 thus reduces the amount of wasted material that does not form part of a panel 20. The layout also minimizes the number of cuts as one or more of the edges 30, 31, 32 are shared with one or more other panels 20.

(25) After the panels 20 are removed from the sheet 100, two of the panels 20 are aligned together (block 204). The panels 20 include the same shape and size and are positioned in an overlapping orientation. This positioning aligns together each of the top edges 30, the lateral edges 31, 32, and the bottom edges 33.

(26) The two panels 20 are then connected together (block 206). The connection can be formed by one or more of sewing and adhesive. In one example as illustrated in FIG. 1, one or more seams 13 connect the panels 20 together. The connection can extend along two or more of the edges 31, 32, 33. In one example as illustrated in FIG. 1, the lateral edges 31, 32 and bottom sides 33 are connected together. The panels 20 can be connected at the edges 31, 32, 33, or can be connected together inward from the edges 31, 32, 33.

(27) One or more of the edges 30, 31, 32, 33 can be treated to prevent unraveling or otherwise fraying during use. This can occur prior to or after the panels 20 are connected together. In one example as illustrated in FIG. 1, the top edges 30 are treated and include seams 14.

(28) An opening 11 is formed along the top edge 30 to provide access to the interior space 12. In one example, the opening 11 extends the entire distance between the corners 50 with the opening 11 extending the entire width W (see FIG. 1).

(29) In another example as illustrated in FIG. 8, the top edges 30 are connected together along sections 62 at the corners 50. The length of the sections 62 can vary. In one example, the sections 62 are the portions of the top edge 30 that are straight and extend inward from the corners 50. The sections 62 result in the opening 11 into the interior space 12 being smaller than the width W of the panels 20. In one example in which the bag 10 is used for cleaning laundry, the sections 62 prevent items within the interior space 12 from escaping through gaps formed along the top edges 30 at the corners 50 when the handle sections 21 are tied together.

(30) The bag 10 can be constructed from a variety of different materials. Examples include but are not limited to mesh, knitted or woven fabric and plastic. In one example, each of the two panels 20 is made from the same material. In another example, the two panels 20 are made from different materials.

(31) In the example described above, the opening 11 is positioned at the top edge of the bag 10. In other examples, the opening 11 is positioned along other edges of the bag 10, such as one of the lateral edges or a bottom edge. In another example, the bag 10 includes two or more openings 11. Handles 21 are positioned at each of the openings 11 to close the opening 11 and secure objects that are positioned within the interior space 12.

(32) One method of using the bag 10 includes separating the handle sections 21 to expose the opening 11. Objects are inserted through the opening 11 and into the interior space 12. After the objects are in the interior space 12, the handle sections 21 are tied together. This closes the opening 11 and prevents the objects from escaping from the interior space 12. The handle sections 21 can be untied to re-open the opening 11 and provide for removal of the objects from the interior space 12 through the opening 11.

(33) In one specific example, the bag 10 is used for laundering objects. With the handle sections 21 untied, the handle sections 21 are separated to expose the opening 11. The objects to be washed are then inserted through the opening 11 and into the interior space 12. The handle sections 21 are then tied together to prevent the objects from escaping from the interior space 12. The bag 10 and the objects are then placed into a washing machine to wash the objects and then a dryer to dry the objects. The bag 10 and objects are removed from the dryer, the handle sections 21 are untied, and the cleaned and dried objects are removed from the interior space 12 through the opening 11. In this example, the bag 10 is constructed from a material that provides for washing and drying.

(34) FIG. 9 illustrates another example that includes a pair of connectors 63 positioned along the top edges 30. The lateral edges 31, 32 and bottom edge 32 are connected together. Gaps 64 are formed along the tops edges 30 between the connectors 63 and the corners 50. The gaps 64 are sized for inserting one of the handle sections 21 to close the top edge 30 without creating any openings that could result in escape of one or more objects. The connectors 63 can extend various lengths along the top edges 30, and can be formed in a variety of manners, including but not limited to stitching, adhesive, and mechanical fasteners such as rivets. In one example, the connectors 63 are bar tacks. During use, after the objects are inserting into the interior space 12, a first one of the handle sections 21 is inserted into one of the gaps 64 and a second one of the handle sections 21 is inserted into the other gap 64. Portions of each of the handle sections 21 extend above the gap 64 and these portions are tied together to close the opening 11. The insertion of the handle sections 21 through the gaps 64 prevents any openings from forming along the top edges 30 adjacent to the corners 50 when the handle sections 21 are tied together.

(35) FIG. 10 illustrates an example in which the bag 10 is formed by a single piece. A fold 29 separates the first and second panels 20a, 20b. Each of the panels 20a, 20b includes a body sections 22a, 22b and a handle section 21a, 21b respectively. During construction, the single piece is folded together with the first and second panels 20a, 20b in an overlapping arrangement. The lateral sides 31, 32 can be connected together to form the enclosed interior space 12. An opening 11 is formed between the handle sections 21a, 21b that leads into the interior space 12.
