Plastic container has a container body having an outer surface and defining a longitudinal axis, at least one recessed panel defined in the container body having an outer perimeter and recessed relative to the outer surface of the container body, the perimeter including opposing longitudinal sides and transverse ends, a transition region defined along the perimeter of the recessed panel, the transition region extending between the recessed panel and the outer surface, and at least one indentation formed in the transition region proximate at least one transverse end of the outer perimeter, the indentation having a height, a width, and a depth, the height of the indentation extending beyond the transition region. The indentation can prevent or reduce container failure due to external forces, such as side loading during a hot-fill process.

A blow molded synthetic resin bottle has a body and an elongated neck with the body providing a shoulder extending about the base of the neck. The neck has a first collar extending thereabout spaced adjacent the shoulder and at least one additional collar extending thereabout adjacent the upper end of the neck. The resin in the neck is substantially unoriented. To produce the bottle, a synthetic resin preform is injection molded with a generally tubular body and the elongated neck. This preform is placed in a blow mold cavity having a body receiving portion and a neck receiving portion that has a recess extending thereabout seating the first collar therein. The additional collar is disposed outwardly of the mold cavity and is disposed on the upper surface of the mold.

A bottle includes a cylindrical body portion in which a plurality of panel portions, which is recessed toward an inside in a radial direction of the body portion, are provided at intervals in a circumferential direction and pillar portions are each provided between the panel portions adjacent to each other in the circumferential direction. The panel portions each have a panel bottom wall portion located at an inside of the body in the radial direction and have a lateral wall portion extending from an outer circumferential edge of the panel bottom wall portion to an outside in the radial direction. A rib which protrudes toward the outside in the radial direction while having a gap with respect to the panel bottom wall portion is provided at the panel bottom wall portion, and a longitudinal lateral wall portion is at least directed in the circumferential direction.

A synthetic resin container that includes a mouth, a body and a bottom, wherein the body includes: an upper end portion; a lower end portion; and an intermediate portion with a polygonal cross-sectional shape having, at vertices thereof, 6 to 12 inclined ridge lines spirally extending around the axis line with a twist angle of 30 or more and 90 or less, the intermediate portion being disposed between the upper end portion and the lower end portion, and wherein when a width of a portion of the body with a greatest diameter is W, and a height from ground to a boundary between the shoulder and the body is H, the synthetic resin container has a shape that satisfies W/H=0.20 to 0.35.

A cylindrical bottle which collapses along helical groove, ridge and connecting rings along its sidewall. When inward force is applied along the bottle's vertical axis, the helical groove rings and connecting rings fold under the ridge rings and remain substantially locked under the ridge rings, thereby causing the sidewall to collapse and remain collapsed until sufficient outward force is applied. When sufficient outward force is applied along its vertical axis, the bottle extends as the distance between its helical groove rings and ridge rings lengthens. Due to the diamond-shaped cross-section of the connecting rings, in conjunction with the silicone composition of the bottle's body, the collapsing and extension of the bottle occur in sequential segments, creating a unique, playful sound and an amusing worm-like movement.

An intermediate bulk container system includes a molded bottle and a pallet. The molded bottle includes a bottom wall and a top wall opposite the bottom wall. A plurality of support columns extend vertically from the bottom wall and define a column thickness. A plurality of sidewalls extending vertically between the bottom wall and the top wall and horizontally between the support columns. The sidewalls define a sidewall thickness that is less than the column thickness.

A synthetic resin container that effectively absorbs reduced pressure generated inside the container due to hot filling to maintain the appearance and shape. A synthetic resin container includes a mouth as a dispensing spout for a content medium, a trunk, extending contiguous to the mouth via a shoulder, and a bottom, closing a lower end of the trunk. The trunk is provided with reduced pressure absorbing panels, which are formed as ribs extending in the vertical direction while twisting in the circumferential direction about a central axis of the trunk and which are arranged side by side in the circumferential direction of the trunk. Twist angle of a lower end with respect to an upper end of each reduced pressure absorbing panel about the central axis is 50 degrees or more.

Provided is a beverage bottle capable of keeping a carbonated beverage left over therein from going flat. The beverage bottle is provided with a bottle body having a volume-reducing structure capable of reducing the volume of the bottle body, a cap capable of sealing an opening of the bottle body, and a shrunken state-maintaining means provided on the bottle body to cause the bottle body having been reduced in volume to be maintained in the reduced volume state. The volume-reducing structure is configured of helical protrusions and recesses respectively formed on the bottle body, and the shrunken state-maintaining means is provided on a trunk section of the bottle body and is configured with a squeezing means for squeezing and maintaining the trunk section having been narrowed by being squeezed along the helical protrusions and recesses.

A method of producing containers with at least one enhanced property, such as high strength, sturdy, durable, and recyclable are described herein. The container so formed have ribs/patterns at the inner surface, leaving the entire outer surface for decorative or marketing purposes. The ribs/pattern is selected from linear lines, curved lines, honeycombs, hexagons, square, rectangular, circular and combination thereof. The containers so formed may have reduced amount of materials used.
