  • the present disclosure relates in general to containers, and in particular, to containers made from flexible material.
  • Fluent products include liquid products and/or pourable solid products.
  • a container can be used to receive, contain, and dispense one or more fluent products.
  • a container can be used to receive, contain, and/or dispense individual articles or separately packaged portions of a product.
  • a container can include one or more product volumes.
  • a product volume can be configured to be filled with one or more fluent products.
  • a container receives a fluent product when its product volume is filled. Once filled to a desired volume, a container can be configured to contain the fluent product in its product volume, until the fluent product is dispensed.
  • a container contains a fluent product by providing a barrier around the fluent product. The barrier prevents the fluent product from escaping the product volume.
  • the barrier can also protect the fluent product from the environment outside of the container.
  • a filled product volume is typically closed off by a cap or a seal.
  • a container can be configured to dispense one or more fluent products contained in its product volume(s). Once dispensed, an end user can consume, apply, or otherwise use the fluent product(s), as appropriate.
  • a container may be configured to be refilled and reused or a container may be configured to be disposed of after a single fill or even after a single use.
  • a container should be configured with sufficient structural integrity, such that it can receive, contain, and dispense its fluent product(s), as intended, without failure.
  • a container for fluent product(s) can be handled, displayed for sale, and put into use.
  • a container can be handled in many different ways as it is made, filled, decorated, packaged, shipped, and unpacked.
  • a container can experience a wide range of external forces and environmental conditions as it is handled by machines and people, moved by equipment and vehicles, and contacted by other containers and various packaging materials.
  • a container for fluent product(s) should be configured with sufficient structural integrity, such that it can be handled in any of these ways, or in any other way known in the art, as intended, without failure.
  • a container can also be displayed for sale in many different ways as it is offered for purchase.
  • a container can be offered for sale as an individual article of commerce or packaged with one or more other containers or products, which together form an article of commerce.
  • a container can be offered for sale as a primary package with or without a secondary package.
  • a container can be decorated to display characters, graphics, branding, and/or other visual elements when the container is displayed for sale.
  • a container can be configured to be displayed for sale while laying down or standing up on a store shelf, while presented in a merchandising display, while hanging on a display hanger, or while loaded into a display rack or a vending machine.
  • a container for fluent product(s) should be configured with a structure that allows it to be displayed in any of these ways, or in any other way known in the art, as intended, without failure.
  • a container can also be put into use in many different ways, by its end user.
  • a container can be configured to be held and/or gripped by an end user, so a container should be appropriately sized and shaped for human hands; and for this purpose, a container can include useful structural features such as a handle and/or a gripping surface.
  • a container can be stored while laying down or standing up on a support surface, while hanging on or from a projection such as a hook or a clip, or while supported by a product holder, or (for refillable or rechargeable containers) positioned in a refilling or recharging station.
  • a container can be configured to dispense fluent product(s) while in any of these storage positions or while being held by the user.
  • a container can be configured to dispense fluent product(s) through the use of gravity, and/or pressure, and/or a dispensing mechanism, such as a pump, or a straw, or through the use of other kinds of dispensers known in the art.
  • Some containers can be configured to be filled and/or refilled by a seller (e.g. a merchant or retailer) or by an end user.
  • a container for fluent product(s) should be configured with a structure that allows it to be put to use in any of these ways, or in any other way known in the art, as intended, without failure.
  • a container can also be configured to be disposed of by the end user, as waste and/or recyclable material, in various ways.
  • One conventional type of container for fluent products is a rigid container made from solid material(s).
  • Examples of conventional rigid containers include molded plastic bottles, glass jars, metal cans, cardboard boxes, etc. These conventional rigid containers are well-known and generally useful; however their designs do present several notable difficulties.
  • Some rigid containers are made by a process shaping one or more solid materials.
  • Other rigid containers are made with a phase change process, where container materials are heated (to soften/melt), then shaped, then cooled (to harden/solidify). Both kinds of making are energy intensive processes, which can require complex equipment.
  • some conventional rigid containers for fluent products can be difficult to decorate.
  • the sizes, shapes, (e.g. curved surfaces) and/or materials of some rigid containers make it difficult to print directly on their outside surfaces.
  • Labeling requires additional materials and processing, and limits the size and shape of the decoration.
  • Overwrapping provides larger decoration areas, but also requires additional materials and processing, often at significant expense.
  • some conventional rigid containers for fluent products can be prone to certain kinds of damage. If a rigid container is pushed against a rough surface, then the container can become scuffed, which may obscure printing on the container. If a rigid container is pressed against a hard object, then the container can become dented, which may look unsightly. And if a rigid container is dropped, then the container can rupture, which may cause its fluent product to be lost.
  • some fluent products in conventional rigid containers can be difficult to dispense.
  • the end user squeezes a rigid container to dispense its fluent product, the end user must overcome the resistance of the rigid sides, to deform the container.
  • Some users may lack the hand strength to easily overcome that resistance; these users may dispense less than their desired amount of fluent product.
  • Other users may need to apply so much of their hand strength, that they cannot easily control how much they deform the container; these users may dispense more than their desired amount of fluent product.
  • the present disclosure describes various embodiments of containers made from flexible material. Because these containers are made from flexible material, these containers can be less expensive to make, can use less material, and can be easier to decorate, when compared with conventional rigid containers. First, these containers can be less expensive to make, because the conversion of flexible materials (from sheet form to finished goods) generally requires less energy and complexity, than formation of rigid materials (from bulk form to finished goods). Second, these containers can use less material, because they are configured with novel support structures that do not require the use of the thick solid walls used in conventional rigid containers. Third, these flexible containers can be easier to print and/or decorate, because they are made from flexible materials, and flexible materials can be printed and/or decorated as conformable webs, before they are formed into containers.
  • the containers of the present disclosure are made from flexible material, they can be configured with sufficient structural integrity, such that they can receive, contain, and dispense fluent product(s), as intended, without failure. Also, these containers can be configured with sufficient structural integrity, such that they can withstand external forces and environmental conditions from handling, without failure. Further, these containers can be configured with structures that allow them to be displayed and put into use, as intended, without failure.
