Definitions

  • This invention relates to a reclosable flexible package that is designed to contain products such as liquid and granules.
  • Flexible packages are used to contain a wide variety of consumer products including liquid and granules, such as shampoos, hair conditioners, laundry detergents, dish detergents, fabric enhancers, liquid soaps, beverages and the like. Some of these flexible packages are made of polymeric film materials such as polyethylene and/or polypropylene. The perimeters of the packages are typically sealed so as to contain the contents.
  • Some flexible packages i.e., refill flexible packages, are thrown away after the whole contents are transferred to another package such as ajar and a bottle.
  • Such flexible packages are normally provided with no reclosing function because they are neither designed nor intended to be reclosed after initial opening. Therefore, such disposable flexible packages are not suitable for storage, carrying or repeated use after initial opening. If current flexible packages are designed for repeated use, then they need a reclosing function such as a cap and a lid.
  • Some flexible packages are provided with a reclosing function like a screw cap.
  • a separate material like a screw cap is sometimes difficult to use. For example, it is usually not easy to open the package by rotating the screw cap with only one hand. The package typically needs to be held with the other hand. Thus, it would be beneficial if a consumer could open the package with one hand.
  • Another objective of the invention is to create a method which enables packages to be reclosed after initial opening.
  • the present invention may control, reduce and/or minimize the leakage of the remaining package contents.
  • the present invention relates to a flexible package with a reclosing function.
  • the package has a first panel and a second panel sealed to each other along their perimeters to form a sealed perimeter surrounding an interior storage space.
  • the sealed perimeter has an upper seal, a bottom seal, a first side seal, and a second side seal opposite the first side seal.
  • the first side seal and the second side seal both connect to the upper seal and the bottom seal.
  • the package also has a spout formed in the sealed perimeter when the package is open along at least a portion of the upper seal.
  • the package further has a discharge channel leading from the spout through the upper seal to the interior storage space.
  • the package has a first recess along the second side seal and a second recess along the upper seal opposite the discharge channel from the first recess.
  • the first recess can engage the second recess such that a fold line is formed that intersects the discharge channel.
  • the reclosing function provided for the package may be beneficial to the consumers because the consumers can easily reclose/reopen the package with one hand. Further, the consumers can handle the package easily with a wet hand.
  • the package herein can be realized by a simple structure of a flexible material with a combination of recesses. As it does not require other special material than the flexible material, the structure can be manufactured at a very low cost. The package herein serves to control, reduce and/or minimize the leakage and spillage of the remaining contents in the package.
  • FIG. 1 is a front plan view of a package according to the present invention before tearing off the tearing notch;
  • FIG. 2 is a front plan view of the package of FIG. 1 after tearing off the tearing notch;
  • FIG. 3 is a front plan view of the package of FIG. 2 in a configuration where the first recess engages the second recess;

  • the package has a spout formed in an end of the sealed perimeter when the package is open along at least a portion of the upper seal.
  • the package has a discharge channel leading from the spout through the upper seal to the interior storage space.
  • the package has a first recess along the second side seal, and a second recess along the upper seal opposite the discharge channel from the first recess.
  • the first recess can engage the second recess such that a fold line is formed that intersects the discharge channel to close the discharge channel.
  • the package may further have a bottom so as to form a self-standing package.
  • a self-standing package may serve to store the package at home, such as on the shelf and on the floor without further support.
  • the bottom may have a material comprising a fold and the bottom connects the first panel to the second panel.
  • the package may have a reinforced area in a location such as adjacent to the first recess, and/or the second recess.
  • the reinforced area may help the flexible package less deteriorated even if reclosing and reopening are repeated.
