Abstract
A container blank including a paperboard shell layer and a core layer. The container blank has a predetermined removable portion the provides for a separable cap portion after the container blank is erected. The container blank can include a lobe for tightly fitting the cap portion to the body portion of the erected container and or provide for a core rim that is located at a rim distance that is a function of position about the longitudinal axis of the container and or include at least one dosing indicia.
Claims15
A container blank comprising:
- a paperboard shell layer comprising two transverse edges on opposing sides of a central axis, a shell bottom edge extending between said transverse edges orthogonal to said central axis, and a shell top edge opposite said shell bottom edge and extending between said transverse edges;
- wherein said shell layer comprises:
- a body portion extending from said shell bottom edge to a lower line of limitation;
- a predetermined removeable portion extending from said lower line of limitation to an upper line of limitation;
- and
- a cap portion extending from said upper line of limitation to said shell top edge;
- and
- a paperboard core layer, wherein when said core layer is in facing relationship with said shell layer said core layer extends from below said lower line of limitation to a core rim above said upper line of limitation;
- wherein when said core layer is in facing relationship with said shell layer said core rim is located at a rim distance from said shell bottom edge as measured parallel to said central axis and said rim distance is a function of distance from said central axis;
- wherein when said core layer is in facing relationship with said shell layer said core rim has a rim distance global maxima and a rim distance global minima relative to said shell bottom edge;
- and
- wherein said core rim is sinusoidal.
A container blank comprising:
- a paperboard shell layer comprising two transverse edges on opposing sides of a central axis, a shell bottom edge extending between said transverse edges orthogonal to said central axis, and a shell top edge opposite said shell bottom edge and extending between said transverse edges;
- wherein said shell layer comprises:
- a body portion extending from said shell bottom edge to a lower line of limitation;
- a predetermined removeable portion extending from said lower line of limitation to an upper line of limitation;
- and
- a cap portion extending from said upper line of limitation to said shell top edge;
- and
- a paperboard core layer, wherein when said core layer is in facing relationship with said shell layer said core layer extends from below said lower line of limitation to a core rim above said upper line of limitation;
- wherein said body portion comprises a lobe immediately below said lower line of limitation and has a body portion length between said transverse edges orthogonal to said central axis immediately below said lobe;
- wherein said lobe has a lobe length orthogonal to said central axis and said lobe length is more than 5% of said body portion length;
- wherein said lobe has a lobe exterior height parallel to said central axis and said lobe has a lobe length to lobe height ratio greater than 1.
