Definitions

  • the present disclosure relates in general to containers, and in particular, to containers made from flexible material, wherein the containers are easy to empty.
  • 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 for fluent products can be expensive to make.
  • 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 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.
  • 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.
  • these flexible containers can be less prone to scuffing, denting, and rupture, because flexible materials allow their outer surfaces to deform when contacting surfaces and objects, and then to bounce back.
  • fluent products in these flexible containers can be more readily and carefully dispensed, because the sides of flexible containers can be more easily and controllably squeezed by human hands.
  • 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.
  • these containers can be configured with sufficient structural integrity, such that they can withstand external forces and environmental conditions from handling, without failure.
  • these containers can be configured with structures that allow them to be displayed and put into use, as intended, without failure.
  • the present disclosure provides various containers that include a resiliently deformable product volume and a dispenser configured to dispense fluent product from the product volume.
  • the product volume When no dispensing force is applied to the product volume, the product volume has an undeformed state and a first interior volume.
  • the product volume When a dispensing force is applied to the product volume, the product volume is resiliently deformable to a deformed state in which the product volume is reduced to a second interior volume less than the first interior volume, and the dispenser can dispense at least some of the fluent product from the product volume.
  • the dispensing force is released, the product volume is self restoring to the undeformed state.

  • 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 decorate, because their flexible materials can be easily printed before they are formed into containers.

  • significant delays at least from the user's perspective, may exist between the time at which the dispensing force is applied and the time at which fluent product is dispensed in direct response to the application of the dispensing force.

Abstract

L'invention concerne divers récipients qui incluent un volume de produit déformable élastiquement et un distributeur conçu pour distribuer un produit fluide depuis le volume de produit. Quand aucune force de distribution n'est appliquée au volume de produit, le volume de produit a un état non déformé et un premier volume intérieur. Quand une force de distribution est appliquée au volume de produit, le volume de produit est déformable élastiquement en un état déformé, dans lequel le volume de produit est réduit à un second volume intérieur inférieur au premier volume intérieur et le distributeur peut distribuer au moins une partie du produit fluide depuis le volume de produit. Quand la force de distribution est relâchée, le volume de produit retrouve complètement son état non déformé.
