A plastic, hot-fillable container which has one or more moveable portions each comprised of intersecting perpendicular recesses. Each of the one or more moveable portions is constructed to move outwardly temporarily without permanently deforming responsive to hot-filling the container with a product. The one or more moveable portions also can be constructed to move inwardly to reduce a portion of an internal vacuum within the filled and capped container.

1. A hot-fillable plastic bottle of generally square shape in bottom end view, but with chamfered corners, the plastic bottle being without any hoop rings and comprising: a threaded upper portion defining an opening into the bottle and having a lip at an end thereof opposite the opening, said threaded upper portion being configured to be threadedly mated with a cap;an elongate neck portion arranged adjacent to said threaded upper portion, said elongate neck portion tapering radially outward in a direction away from said threaded upper portion; a body portion having four sidewalls and being arranged adjacent to a widest part of said elongate neck portion, each said sidewall having an outer surface and a recessed moveable panel with a generally rectangular perimeter in a side view of the bottle, each recessed moveable panel being recessed relative to the outer surface of the sidewall with long sides of the recessed moveable panel running vertically in a longitudinal direction of the bottle, and the recessed moveable panel including: a vertically oriented groove centrally aligned within the perimeter of the recessed moveable panel and having a maximum depth thereof at a first depth relative to an outer surface of the recessed moveable panel; andthree horizontally oriented grooves each having a maximum depth thereof relative to the outer surface of the recessed moveable panel at a second depth greater than the first depth, each of said three horizontally oriented grooves interrupting said vertically oriented groove, and said vertically extending groove having a portion arranged above a top one of said horizontally oriented grooves in the longitudinal direction of the bottle and a portion arranged below a bottom one of said horizontally oriented grooves in the longitudinal direction of the bottle;and a base portion arranged adjacent to said body portion and having a lower-most portion thereof defining a standing surface of the bottle,wherein each of said recessed moveable panels is configured (i) to flex outward temporarily without permanently deforming, rolling-out, or inverting in response to an internal pressure within the bottle, and (ii) to flex inward in response to an internal vacuum. 2. The plastic bottle according to claim 1, wherein each of said recessed moveable panels is configured to flex outward temporarily to break a surface plane of a corresponding one of said four sidewalls without permanently deforming, rolling-out, or inverting in response to the internal pressure. 3. The plastic bottle according to claim 1, wherein the flexing inward of each said recessed moveable panel is to a respective position inward of an as-formed position of said recessed moveable panel. 4. The plastic bottle according to claim 1, wherein the flexing inward of said recessed moveable panels is by a same amount or substantially a same amount for each said recessed moveable panel. 5. The plastic bottle according to claim 1, wherein the flexing outward of said recessed moveable panels is by a same amount or substantially a same amount for each said recessed moveable panel. 6. The plastic bottle according to claim 1, wherein the flexing inward of the recessed moveable panels compensates for an entirety of the internal vacuum. 7. The plastic bottle according to claim 6, wherein the flexing inward of the recessed moveable panels compensates for an entirety of the internal vacuum and creates a positive pressure within the bottle. 8. The plastic bottle according to claim 1, further comprising a push-up bottom end portion arranged axially inward of the standing surface of said base portion. 9. The plastic bottle according to claim 8, wherein the flexing inward of the recessed moveable panels compensates for a portion of the internal vacuum, and the push-up bottom end portion is configured to move toward the interior of the bottle to remove a remaining portion of the internal vacuum, and wherein movement toward the interior of the bottle of the push-up bottom end portion creates a positive pressure within the bottle. 10. The plastic bottle according to claim 8, wherein the push-up bottom end portion is configured and operative to always be at or above the standing surface of the bottom portion of the bottle. 11. A plastic container comprising: an upper portion defining an opening into an internal volume of the container;a body portion having a sidewall with an outer surface and a predefined moveable portion recessed relative to the outer surface of the sidewall, said predefined moveable portion including within a perimeter thereof a first recess oriented vertically in a first direction and a second recess oriented in a second direction perpendicular to the first direction, the first recess having a first maximum depth relative to an outer surface of the moveable portion, and the second recess having a second maximum depth relative to the outer surface of the moveable portion, the second maximum depth being greater than the first maximum depth, the second recess physically bisecting the first recess so as to divide the first recess into a first recess portion of the first recess and a second recess portion of the first recess; anda base portion for supporting the plastic container in an upright position. 12. The plastic container according to claim 11, wherein said predefined moveable plastic portion further comprises a third recess oriented in the second direction and a fourth recess oriented in the second direction, the third recess physically crossing the first recess portion of the first recess, and the fourth recess physically crossing the second recess portion of the first recess; wherein the third and fourth recesses each has a maximum depth relative to the outer surface of the moveable portion greater than the first maximum depth of the first recess portion. 13. The plastic container according to claim 12, wherein the third recess oriented in the second direction physically crosses the first recess so as to split the first recess into the first recess portion and a third recess portion, the third recess portion being at one extremity of the first recess,wherein the fourth recess oriented in the second direction physically crosses the first recess so as to split the first recess into the second recess portion and a fourth recess portion, the fourth recess portion being at another extremity of the first recess opposite to the one extremity of the first recess,wherein the third and fourth recesses have the same dimensions,wherein the second recess has a maximum width greater than a maximum width of the third and fourth recesses,wherein the first and second recess portions have the same dimensions, andwherein the third and fourth recess portions have the same dimensions. 14. The plastic container according to claim 11, wherein the container has a plurality of predefined moveable portions of similar configuration as said predefined moveable portion. 15. The plastic container according to claim 11, wherein the sidewall defines a surface plane, the predefined moveable portion being entirely recessed with respect to the surface plane of the sidewall and surrounded by a continuous downward transition from the sidewall. 16. The plastic container according to claim 11, wherein the predefined moveable portion is configured and operative to move from a first, as-formed position outwardly to a second position, and to move inwardly to a third position after movement thereof to the second position.
