Definitions
- This invention relates generally to the field of plastic containers, and more particularly to plastic containers that are designed to accommodate volumetric expansion and contraction such as that inherent to the hot-fill packaging process or to packaging applications where internal pressurization is anticipated.
- PET polyethylene terephthalate
- PET containers are typically manufactured using the stretch blow molding process. This involves the use of a preform that is injection molded into a shape that facilitates distribution of the plastic material within the preform into the desired final shape of the container.
- the preform is first heated and then is longitudinally stretched and subsequently inflated within a mold cavity so that it assumes the desired final shape of the container. As the preform is inflated, it takes on the shape of the mold cavity. The polymer solidifies upon contacting the cooler surface of the mold, and the finished hollow container is subsequently ejected from the mold.
- Hot fill containers are designed to be used with the conventional hot fill process in which a liquid or semi-solid product such as fruit juice, sauce, salsa, jelly or fruit salad is introduced into the container while warm or hot, as appropriate, for sanitary packaging of the product. After filling, such containers undergo significant volumetric shrinkage as a result of the cooling of the product within the sealed container. Hot fill type containers accordingly must be designed to have the capability of accommodating such shrinkage. Typically this has been done by incorporating one or more vacuum panels into the side wall of the container that are designed to flex inwardly as the volume of the product within the container decreases as a result of cooling.
- the vacuum panel regions of conventional hot fill containers are characterized by having surfaces that are designed to deflect inwardly when the product within the sealed container undergoes shrinkage.
- the amount of volumetric contraction, also referred to as vacuum uptake, that can be provided by a conventional vacuum panel is limited by the size of the panel.
- the design of such containers is often influenced by the aesthetic preferences of manufacturers, which in some instances can limit the size of the vacuum panels to the extent that makes it difficult or impossible to achieve the necessary vacuum uptake capacity.
- the container body has a sidewall that is shaped to define at least one flexible panel.
- the flexible panel has a central longitudinal axis, an upper portion, a lower portion and a central portion.
- the central portion of the flexible panel has a width that is greater than a respective width of at least one of the upper and lower portions.
- the flexible panel is substantially flat as viewed in a longitudinal cross-section taken along the central longitudinal axis.
- a plastic container is adapted for adjustment to internal volumetric changes such as those that occur during the hot fill process includes a container body defining an internal space.
- the container body has a sidewall that is shaped to define at least one flexible panel.
- the flexible panel has a central longitudinal axis, an upper portion, a lower portion and a central portion.
- the central portion of the flexible panel has a width that is greater than a respective width of at least one of the upper and lower portions.
- the central portion has a transverse radius of curvature that is greater than a transverse radius of curvature of at least one of the upper portion and said lower portion.

Abstract
Description
- 1.Field of the Invention
- This invention relates generally to the field of plastic containers, and more particularly to plastic containers that are designed to accommodate volumetric expansion and contraction such as that inherent to the hot-fill packaging process or to packaging applications where internal pressurization is anticipated.
- 2. Description of the Related Technology
- Many products that were previously packaged using glass containers are now being supplied in plastic containers, such as containers that are fabricated from polyesters such as polyethylene terephthalate (PET).
- PET containers are typically manufactured using the stretch blow molding process. This involves the use of a preform that is injection molded into a shape that facilitates distribution of the plastic material within the preform into the desired final shape of the container. The preform is first heated and then is longitudinally stretched and subsequently inflated within a mold cavity so that it assumes the desired final shape of the container. As the preform is inflated, it takes on the shape of the mold cavity. The polymer solidifies upon contacting the cooler surface of the mold, and the finished hollow container is subsequently ejected from the mold.
- Hot fill containers are designed to be used with the conventional hot fill process in which a liquid or semi-solid product such as fruit juice, sauce, salsa, jelly or fruit salad is introduced into the container while warm or hot, as appropriate, for sanitary packaging of the product. After filling, such containers undergo significant volumetric shrinkage as a result of the cooling of the product within the sealed container. Hot fill type containers accordingly must be designed to have the capability of accommodating such shrinkage. Typically this has been done by incorporating one or more vacuum panels into the side wall of the container that are designed to flex inwardly as the volume of the product within the container decreases as a result of cooling.
- Typically, the vacuum panel regions of conventional hot fill containers are characterized by having surfaces that are designed to deflect inwardly when the product within the sealed container undergoes shrinkage. The amount of volumetric contraction, also referred to as vacuum uptake, that can be provided by a conventional vacuum panel is limited by the size of the panel. The design of such containers is often influenced by the aesthetic preferences of manufacturers, which in some instances can limit the size of the vacuum panels to the extent that makes it difficult or impossible to achieve the necessary vacuum uptake capacity.
- A need therefore exists for an improved vacuum panel configuration that achieves a maximal amount of vacuum uptake capacity in relation to the size of the vacuum panel.
- Accordingly, it is an object of the invention to provide a plastic container having an improved vacuum panel configuration that achieves a maximal amount of vacuum uptake capacity in relation to the size of the vacuum panel.
- In order to achieve the above and other objects of the invention, a plastic container according to a first aspect of the invention that is adapted for adjustment to internal volumetric changes such as those that occur during the hot fill process includes a container body defining an internal space. The container body has a sidewall that is shaped to define at least one flexible panel. The flexible panel has a central longitudinal axis, an upper portion, a lower portion and a central portion. The central portion of the flexible panel has a width that is greater than a respective width of at least one of the upper and lower portions. The flexible panel is substantially flat as viewed in a longitudinal cross-section taken along the central longitudinal axis.
- A plastic container according to a second aspect of the invention is adapted for adjustment to internal volumetric changes such as those that occur during the hot fill process includes a container body defining an internal space. The container body has a sidewall that is shaped to define at least one flexible panel. The flexible panel has a central longitudinal axis, an upper portion, a lower portion and a central portion. The central portion of the flexible panel has a width that is greater than a respective width of at least one of the upper and lower portions. The central portion has a transverse radius of curvature that is greater than a transverse radius of curvature of at least one of the upper portion and said lower portion.
- These and various other advantages and features of novelty that characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, for a better understanding of the invention, its advantages, and the objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to the accompanying descriptive matter, in which there is illustrated and described a preferred embodiment of the invention.
