Definitions

  • the present invention relates to product packaging for solid products.
  • Solid products provide many advantages over using non-solid products. For example, solid products are typically less expensive to ship because they are usually formulated as concentrates that are then diluted prior to use. Solid products can be formulated using aggressive chemistry that provides better cleaning including strong acids and strong bases. Solid products with such aggressive chemistry are generally considered safer than comparable non-solid or liquid products because solid products cannot spill like non-solid or liquid products.
  • Solid products are dispensed in solid product dispensers to create a concentrated use solution or a use solution. Some solid products are caustic or corrosive and should not be handled by coming into direct contact with the solid products. This is particularly true in industrial laundry, warewashing, and floor care products.
  • Thermoformed blister packs and packages with lids are commonly used to package solid products.
  • these types of packages typically require the user to remove the backs or the lids from the packages and drop the solid products into the dispensers. This technique exposes the user to contact the solid products directly, which is not desirable.
  • Another type of packaging in which solid products are packaged is shrink wrapped films. Small holes in the film allow the evacuation of otherwise trapped air as the film shrinks to conform to the shape of the solid product. These small holes allow moisture from the atmosphere to enter the package, which may cause the solid product to swell and at least partially dissolve. Further, the user may directly contact the solid product that has escaped through these small holes. Thus, it is challenging to load solid products into dispensers without touching the solid products.
  • One problem related to the manufacture, storage, and use of solid products including extruded acidic and alkaline solid products is the stability of the solid products.
  • the solid products Upon exposure to environmental conditions such as humidity, the solid products can absorb humidity resulting in a softening or dissolution of at least a portion of the solid products.
  • the absorption of humidity can result in softened layers of the solid products rendering the solid products difficult to handle and properly dispense.
  • the absorption of humidity can result in the creation of a liquid product that can slump or flow from the surface of the solid product creating a pool of highly caustic material.
  • the instability can also cause problems in dispensing of the products.
  • the softened surface or liquid material that can flow from the surface can cause spikes of material during dispensing resulting in uneven concentrations being dispensed.
  • a spray of water is directed onto a surface of the solid product.
  • the spray removes a small portion of the solid product in the form of an aqueous concentrate use solution. If the solid product is at least partially softened or liquefied, the aqueous concentrate use solution will be too concentrated.
  • JP 2003 182716A describes a vessel for bite-sized food having a base including a top, sides and a bottom, thus forming a cavity to receive the foodstuff. Also a lid and a seal interconnecting the top of the base and the lid may be included.
  • the vessel according D1 further comprises a groove in the vessel body.
  • US2,920,417 is related to a detergent-solution dispensing container without a lid and a seal to cover the top of the base.
  • US Re 32,763 discloses a solid cast detergent used in automatic washing machines. It is surrounded on all but its upper surface by a mold. A texture on the exterior surface or a seal are not disclosed.
  • One aspect of the present invention provides a product packaging containing a solid product block comprising

  • shrink wrapped blocks For the shrink wrapped blocks, no significant changes were noticeable under ambient conditions. The blocks retained a lot of moisture, were soft, and changed in color in areas where moisture was absorbed under the accelerated conditions. The shrink wrapped blocks did not provide an acceptable moisture barrier.
  • the nature of shrink films requires that there be a process for the evacuation of air as the film shrinks around the product being encased.
  • the two options for air evacuation typically used are punched holes or pin perforations in the film. Both options leave an exposed area of product to atmospheric conditions, specifically moisture uptake, the rate of which can be controlled by the size of the evacuation holes or perforations, but not less than 0.02 g (100 sq. in) 654.2 cm 2 as provided by the base portion of the tray packages referenced earlier.
  • the base portion of the tray packages reduces the amount of moisture uptake by the product.
  • tray packages For the tray packages, no significant changes were noticeable under ambient conditions. The blocks retained their firmness under the accelerated conditions. The tray packages provided an acceptable moisture barrier.
