Definitions

  • the present invention refers to a closure. More specifically, the present invention refers to a closure for a container holding liquid, such as food items and concentrated cleaning products, and/or powdered products, such as condiments and powdered milk, wherein the closure has a flow control member being an opening-closing flap.
  • Containers for fluent substances are usually provided with closures in order to avoid the spilling of their contents.
  • closures present an opening for the release of the contents of the container.
  • closures present a closing means, such as an overcap or movable lid, which can be freely opened and closed, avoiding, thus, the accidental release of the container contents.
  • Concentrated liquid substances are dense liquids such as cleaning products and food sauces or condiments.
  • liquid hand soaps, shampoos, oils, tomato sauces, and food condiments like ketchup and mustard. Due to the dense nature of these concentrated substances, the accidental spilling thereof should be prevented, especially in areas that may be stained or cause likewise problems. Thereby, it is required that containers storing these kinds of substances have a flow-control closure, preventing the liquid inside from dripping or leaking therefrom in an uncontrolled manner.
  • a way for controlling such container flow is with a closure on the vessel containing the stored substance and which only releases the contained substance through squeezing of the container body by the user.
  • this type of container is used to store a concentrated liquid, at least two problems may occur: first, if the container closure does not have good liquid flow control, undesirable splashes may occur whenever the container is squeezed, and the concentrated liquid flow falls over inappropriate areas. Then, the released substance may stain surrounding areas, as well as the users’ clothes and skin.
  • the level of concentrated liquid left in the container may be reduced during repeated uses. In this case, the amount of concentrated liquid dispensed through the same compression force may change significantly and disadvantageously as the level of liquid concentrate changes within the container.
  • Liquid substances in particular food products, may also be susceptible to deterioration due to their exposure to a variety of microbial agents, which makes a permanently open closure not a good solution.
  • microbial agents which makes a permanently open closure not a good solution.
  • the state of the art discloses a number of solutions concerning opening/closing closures that also present some kind of flow control, in some way.
  • these solutions fail to present an efficient control of flow, as well as they need a closing element that may be opened and closed, consisting of an efficient construction..
  • the closure is fixed to a container having an opening through which the product can be dispensed therein, such closure comprises a main body and a flap for controlling the product flow from a round opening.
  • the closure includes a main body which includes a front side and side walls extending upwardly beyond the front side.
  • the front side further includes an opening to dispense the fluent product from the interior of the container.
  • the closure further includes a flap for selectively opening and closing the opening to control the fluent product flow from the opening.
  • the side walls of the main body include a recess and the flap is pivotally connected to the main body on the front side at a location spaced from the side walls and is movable between i) a closed position occluding the opening and extending into the recess, and ii) an open position exposing the opening and moved away from the recess.
  • the front side of the main body includes two curved gaps positioned opposite each other.
  • the front side of the main body further includes a hole for retaining the flap in the open position.
  • the flap has a curved, laminar shape with rounded corners and is secured on the front side of the main body within a circular notch by a pivot on the flap.
  • the flap includes an indicium for indicating a location of a cylindrical closing member extending from a posterior portion of the flap for occluding the opening in the closed position of the flap.
  • the flap includes an aperture that is configured to align with the recess in the closed position of the flap.
  • the flap has a different color than the main body of the closure to improve usability, enhancing the visibility of the flap position within the main body of the closure.
  • the flap is located laterally inwardly from the side walls in the open position and the closed position.
  • the closure is in combination with a container of a fluent substance.
  • the container is configured for use in an inverted or upside-down position.
  • a method of opening a closure includes the step of obtaining a closure.
  • the closure includes a main body which includes a front side and side walls extending upwardly beyond the front side.
