A product display apparatus for displaying a plurality of bottles (3, 101) each having a respective neck with a first width at a first height of the bottle and a wider portion thereabove, said apparatus comprising: a sliding bottle support structure including left and right slide structures (47, 49, 129, 131, 199, 205) spaced from each other so as to define a slot therebetween of substantially uniform width over a sliding bottle travel path of the bottle support structure formed by the slide structures; wherein said uniform width is such that the bottles are slidingly supported with the necks of the bottles (3, 101) extending upwardly through the slot and the widened portion thereof resting slidingly on the slide structures; wherein the bottle travel path includes a first substantially straight inclined portion wherein the slide structures (47, 49, 129, 131) extend linearly and slopingly rearwardly and upwardly at a first angle; a second substantially straight inclined portion wherein the slide structures (47, 49, 129, 131) extend linearly and slopingly rearwardly and upwardly at a second angle that is less steep than the first angle; and an intermediate curved portion connecting a rearward end of the first substantially straight portion and a rearward end of the second substantially straight portion such that the bottles may move slidingly on the slide structures rearward so as to travel through the first substantially straight portion, through the intermediate curved portion, and through the second substantially straight portion so as to be removed from a front end of the second substantially straight portion; the slide structures (199, 205) in the intermediate curved portion sloping downwardly from the rearward end of the first substantially straight portion to the rearward end of the second substantially straight portion at a third angle; wherein the first, second and third angles, and a level of friction between the bottles and the slide structures is such that bottles may be pushed slidingly rearward up the first substantially straight portion to an apex in the bottle travel path at a beginning of the intermediate curved portion, and when pushed beyond said apex, said bottles slide by force of gravity through the intermediate curved portion and through the second substantially straight portion to the front end of the second substantially straight portion. a sliding bottle support structure including left and right slide structures (47, 49, 129, 131, 199, 205) spaced from each other so as to define a slot therebetween of substantially uniform width over a sliding bottle travel path of the bottle support structure formed by the slide structures; wherein said uniform width is such that the bottles are slidingly supported with the necks of the bottles (3, 101) extending upwardly through the slot and the widened portion thereof resting slidingly on the slide structures; wherein the bottle travel path includes a first substantially straight inclined portion wherein the slide structures (47, 49, 129, 131) extend linearly and slopingly rearwardly and upwardly at a first angle; a second substantially straight inclined portion wherein the slide structures (47, 49, 129, 131) extend linearly and slopingly rearwardly and upwardly at a second angle that is less steep than the first angle; and an intermediate curved portion connecting a rearward end of the first substantially straight portion and a rearward end of the second substantially straight portion such that the bottles may move slidingly on the slide structures rearward so as to travel through the first substantially straight portion, through the intermediate curved portion, and through the second substantially straight portion so as to be removed from a front end of the second substantially straight portion; the slide structures (199, 205) in the intermediate curved portion sloping downwardly from the rearward end of the first substantially straight portion to the rearward end of the second substantially straight portion at a third angle; wherein the first, second and third angles, and a level of friction between the bottles and the slide structures is such that bottles may be pushed slidingly rearward up the first substantially straight portion to an apex in the bottle travel path at a beginning of the intermediate curved portion, and when pushed beyond said apex, said bottles slide by force of gravity through the intermediate curved portion and through the second substantially straight portion to the front end of the second substantially straight portion.
