Abstract

An insulated packaging assembly can include a box having a plurality of sides and a bottom; a liner having a plurality of sides defined by a plurality of end panels; and at least one separation feature connected to the side of the liner between the side of the liner and the corresponding side of the box; wherein each end of each end panel defines a protrusion tab, and a first separation feature of the at least one separation feature can include a protrusion tab of one of the end panels extending beyond an outer surface of an adjacent end panel.

First claim

That which is claimed is:

1 . An insulated packaging assembly comprising:
a box, the box having a plurality of sides and a bottom, the box defining an opening at a top end; and a liner, the liner comprising
a plurality of sides, each side of the liner being defined by an end panel having a pair of ends and corresponding to one side of the box such that the box and the liner comprise the same number of sides;
a bottom; and
at least one separation feature connected to each side of the liner, wherein each separation feature is arranged between the side of the liner and the corresponding side of the box;
wherein
each end of each end panel defines a protrusion tab, and
a first separation feature of the at least one separation feature connected to each side of the liner comprises the protrusion tab of one of the end panels extending beyond an outer surface of an adjacent end panel.

2 . The insulated packaging assembly of claim 1 , wherein each end of each end panel further defines a recession, and the first separation feature of the at least one separation feature further comprises the protrusion tab of the one of the end panels being arranged in the recession of the adjacent end panel.

3 . The insulated packaging assembly of claim 1 , further comprising a liner top, the liner top being in contact with each of the sides of the liner.

4 . The insulated packaging assembly of claim 1 , wherein each side of the liner is arranged an insulation distance from the corresponding side of the body.

5 . A liner blank comprising:
a first central panel connected to a second central panel by a line; a third central panel connected to the second central panel by a line; a fourth central panel connected to the third central panel by a line; a first end panel connected to the first central panel by a line, the first end panel defining
a first end, the first end defining a protrusion tab;
a second end defining a recession; and
a panel end;
a second end panel connected to the second central panel by a line, the second end panel defining
a first end of the second end panel, the first end of the second end panel being coincident with the second end of the first end panel, the first end of the second end panel defining a protrusion tab;
a second end of the second end panel defining a recession; and
a panel end of the second end panel;
a third end panel connected to the third central panel by a line, the third end panel defining
a first end of the third end panel, the first end of the third end panel being coincident with the second end of the second end panel, the first end of the third end panel defining a protrusion tab;
a second end of the third end panel defining a recession; and
a panel end of the third end panel;
a fourth end panel connected to the fourth central panel by a line, the fourth end panel defining
a first end of the fourth end panel, the first end of the fourth end panel being coincident with the second end of the third end panel, the first end of the fourth end panel defining a protrusion tab;
a second end of the fourth end panel defining a recession; and
a panel end of the fourth end panel.

6 . The liner blank of claim 5 , wherein each protrusion tab is filleted.

7 . The liner blank of claim 6 , wherein the protrusion tab laterally extends each first end and wherein the recession laterally contracts each second end.

8 . The liner blank of claim 6 , wherein each recession is filleted.

9 . The liner blank of claim 6 , wherein at least one surface of the liner blank is covered in temperature-preserving film.

10 . The liner blank of claim 5 further comprising:
a first fold panel connected to the first central panel by a line;
a bottom panel connected to the second central panel by a line;
a second fold panel connected to the third central panel by a line; and
an intermediary panel connected to the fourth central panel by a line.

11 . The liner blank of claim 10 further comprising a connection panel connected to the fourth central panel by a line.

12 . The liner blank of claim 11 further comprising a connection protrusion extending from the second end of the fourth end panel proximate the panel end of the fourth end panel.

13 . The liner blank of claim 11 , wherein each panel end is aligned.

14 . The liner blank of claim 11 , wherein each fold panel comprises:
a main base panel; and a connection panel connected to the main base panel by a line.

15 . The liner blank of claim 5 , wherein:
the first end of the first end panel further defines a recess; the second end of the first end panel further defines a protrusion tab; the first end of the second end panel further defines a recess; the second end of the second end panel further defines a protrusion tab; the first end of the third end panel further defines a recess; the second end of the third end panel further defines a protrusion tab; the first end of the fourth end panel further defines a recess; the second end of the fourth end panel further defines a protrusion tab.

16 . An insulated packaging assembly comprising:
a box, the box comprising
a first side having an inner surface;
a second side connected to an end of the first side, the second side having an inner surface;
a third side connected to an end of the second side, the third side having an inner surface;
a fourth side connected to an end of the third side and another end of the first side, the fourth side having an inner surface; and
a bottom connected to an end of each side, the bottom having an inner surface;
a liner formed from a blank, the liner comprising:
a first central panel connected to a second central panel by a line;
a third central panel connected to the second central panel by a line;
a fourth central panel connected to the third central panel by a line;
a first end panel connected to the first central panel by a line, the first end panel defining
a first end, the first end defining a protrusion tab;
a second end defining a recession; and
a panel end;

a second end panel connected to the second central panel by a line, the second end panel defining
a first end of the second end panel, the first end of the second end panel being coincident with the second end of the first end panel, the first end of the second end panel defining a protrusion tab;
a second end of the second end panel defining a recession; and
a panel end of the second end panel;

a third end panel connected to the third central panel by a line, the third end panel defining
a first end of the third end panel, the first end of the third end panel being coincident with the second end of the second end panel, the first end of the third end panel defining a protrusion tab;
