摘要： A plastic container, particularly suited for returnable and refillable PET carbonated beverage bottles, having an enhanced level of crystallinity in the sidewall but maintaining a very low level of crystallinity in the base. The container can withstand higher caustic wash temperatures and exhibits reduced flavor carryover from one product to another. The container is formed from a preform, wherein a sidewall-forming section of the preform is initially expanded and then heated to contract and crystallize the same before being reexpanded, and a base-forming portion of the preform is shielded from the heat treatment and expanded either before or after the heat treatment.

摘要： Pressurized plastic container having the appearance of ribs but with substantially reduced creep and without delamination, i.e., having an enhanced shelf life compared to prior art ribbed containers. In multilayer containers, the scribe lines reduce delamination of the layer structure so as to avoid loss of transparency and/or barrier properties. The reduction in creep is particularly useful for smaller volume containers having a greater surface area to volume ratio.

摘要： A hot-fillable plastic container having a panel section of a size suitable for gripping the container in one hand. The panel section includes two opposing vertically-elongated and radially-indented vacuum panels, and two opposing horizontally-disposed and radially-indented finger grips. Each vacuum panel preferably has an invertible central wall portion movable from a convex first position prior to hot-filling of the container, to a concave second position under vacuum pressure following hot-filling and sealing of the container.

摘要： A method and apparatus for forming a plastic container having an enhanced level of crystallinity for improved thermal stability. A substantially amorphous and transparent preform in the molecular orientation temperature range is expanded by a pulse-blow process one or more times to form an intermediate article, prior to a final expansion step to the full container dimensions. The pulse-blow step is conducted at a relatively high-strain rate to maximize the formation of crystal nucleation sites, followed by deflation to relax the amorphous orientation, and the final expansion step is conducted at a low-strain rate to minimize the amorphous orientation. The resulting container has a higher thermal deformation temperature and reduced thermal shrinkage and is particularly adapted for use as a refillable or hot-fill beverage container. A blow-mold and fluid supply apparatus is provided, including a metering chamber and piston, for alternatively supplying the high and low-strain rate inflations.

摘要： A squeezable container for dispensing a product out the open end of the container, including a collapsible inner layer and a resilient outer layer. The container is an integral body formed by expansion from a multi-layer preform, and preferably consists of one or more layers of polyethylene terephthalate (PET) separated by an adjacent boundary layer, such as a barrier layer of ethylene vinyl alcohol (EVOH). A one-way check valve is provided at the outer layer to restrict the flow of air into a chamber which is formed between the inner and outer layers as the inner layer collapses, and preferably a second check valve is provided in the open dispensing end of the container to prevent air from being drawn into the container when the outer layer is released. The container is economical to manufacture, light in weight, easy to handle, can be made of recycled materials, and is "product efficient" in that substantially all of the product can be dispensed from the container during use.

摘要： A squeezable container with a paneled side wall which resists permanent deformation or denting when squeezed, and which preferably can be hot-filled. The container can be made substantially thinner than known hot-fill containers and includes a stepped vacuum panel profile for greater flexibility and resilience (bounce back). A circumferential ring is provided in the side wall to prevent ovalizing. The post walls (surrounding the vacuum panels) are stiffened to prevent vacuum collapse, by providing a substantially perpendicular junction between the vacuum panel and post wall, sufficient post wall depth, and/or reinforcing ribs in the post walls.
