Abstract
The present invention is a directed to a container provided with a liner formed in the mold which changes the properties of the container, when compared to a container not having the liner, and methods of forming same. The liner may exhibit absorption properties, it may release an agent into the surrounding environment, it may undergo some action in response to a condition or thing in the environment, such as the presence of water or a gas. It may provide a barrier, and/or it may exhibit permeability.
Claims64
A container provided with a liner, wherein the container and liner are formed in a mold, the container comprised of a container body formed of a molded polymeric material, the container body defining a storage space in which an item can be stored, and wherein a molded liner is provided on at least a portion of a storage space side of the container body, wherein the liner is a composition comprising an absorption material.
A container provided with a liner, wherein the container and liner are formed in a mold, the container comprised of a container body formed of a molded polymeric material, the container body defining a storage space in which an item can be stored, wherein a liner is provided on at least a portion of a storage space side of the container body, wherein the liner is a composition comprising a releasing material.
A container provided with a liner, wherein the container and liner are formed in a mold, the container comprised of a container body formed of a molded polymeric material, the container body defining a storage space in which an item can be stored, wherein a liner is provided on at least a portion of a storage space side of the container body, wherein the liner is a composition comprising an activation material.
A container provided with a liner, wherein the container and liner are formed in a mold, the container comprised of a container formed of a molded polymeric material, the container body defining a storage space in which an item can be stored, wherein a liner is provided on at least a portion of a storage space side of the container body, wherein the liner comprises a barrier material.
The container of claim wherein the liner exhibits oxygen barrier properties.
The container of claim wherein the liner is comprises ethylene vinyl alcohol.
A container provided with a liner, wherein the container and liner are formed in a mold, the container comprised of a container body formed of a molded polymeric material, the container body defining a storage space in which an item can be stored, wherein a liner is provided on at least a portion of a storage space side of the container body, wherein the liner comprises a permeability-enhancing material.
A method of forming a container having a lining formed in the mold comprised of the steps of:
- inserting a liner composition within a mold for forming a container, the liner composition comprising a material selected from the group consisting of an absorption material, a releasing material, a barrier material, and an activation material;
- subsequently inserting a flowable plastic material into the mold at a position which locates the liner on an interior position of the container;
- and closing the mold.
A method of forming a container having a liner formed in the mold, comprising the steps of:
- in a first position, placing a first liner composition on the core or a mold, the first liner composition comprising a material selected from the group consisting of an absorption material, a releasing material, a barrier material, and an activation material;
- rotating the core to a second position;
- closing the mold;
- injecting a first plastic composition into the mold over the first liner;
- opening the mold;
- rotating the core to a third position;
- placing a second liner over the core containing the injection molded plastic composition and the first liner, the second liner composition comprising a material selected from the group consisting of an absorption material, a releasing material, a barrier material, and an activation material;
- rotating the core to a fourth position;
- closing the mold;
- injecting a second plastic composition into the mold;
- and
- ejecting the container from the mold.
A container provided with a liner, wherein the container and liner are formed in a mold, the container comprised of a container body formed of a molded polymeric material, the body defining a storage space in which an item can be stored, wherein a liner is provided on at least of a portion of an storage space side of the container walls, wherein the liner includes a label layer and a liner composition layer, the liner composition layer comprising a material selected from the group consisting of an absorption material, a releasing material, a barrier material, and an activation material.
A container provided with a liner, wherein the container and liner are formed in a mold, the container comprised of a container body having walls formed of a molded polymeric materials, the walls defining a storage space in which an item can be stored, wherein a liner is provided on at least of a portion of a storage space side of the container walls, wherein the liner is comprised of a skin layer adjacent the storage space side of the container and a liner composition layer adjacent to the container walls comprised of a material selected from the group consisting of an absorption material, a releasing material, a barrier material, and an activation material.
A container provided with a liner, wherein the container and liner are formed in a mold, the container comprised of container body layers and liner layers, comprised of
- a first molded inner liner layer, the first liner layer including a material selected from the group consisting of an absorption material, a releasing material,
- a barrier material, and an activation material;
- a first molded container body layer comprised of a first polymeric composition overlayed over the first liner layer;
- a second molded intermediate liner layer, the second molded intermediate liner layer including a material selected from the group consisting of an absorption material, a releasing material, a barrier material, and an activation material;
- the second molded intermediate liner overlayed over the first molded container body layer;
- and
- a second molded container body layer comprised of a second polymeric composition overlayed over the second molded liner layer.
