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.
- One aspect of the present invention provides a product packaging for a solid product comprising a base, a lid, and a seal.
- the base has a top, sides, and a bottom forming a cavity configured and arranged to receive a solid product, and the base has an exterior surface.
- a texture is on the exterior surface of the base, whereby the texture enhances a user's ability to grip the base when the base is inverted.
- the seal interconnects the top of the base and the lid and allows the lid to be peeled away from the top of the base.
- a product packaging having a base, a lid, and a seal is obtained.
- the base has a top, sides, and a bottom forming a cavity configured and arranged to receive the solid product.
- the seal interconnects the top of the base and the lid and allows the lid to be grasped and peeled to separate the lid from the top of the base.
- a portion of the peelable lid is grasped, and the peelable lid is peeled away from the base.
- the base is held and inverted so that the bottom of the base is in an upward orientation and the top of the base is in a downward orientation.
- the solid product is allowed to slide out of the cavity into the solid product dispenser.
- the product packaging has a base, a lid, and a seal.
- the base has a top, sides, and a bottom forming a cavity configured and arranged to receive the solid product, and the base has an exterior surface with a texture on at least a portion of the exterior surface.
- the seal interconnects the top of the base and the lid and allows the lid to be grasped and peeled to separate the lid from the top of the base.
- the product packaging is obtained. A portion of the peelable lid is grasped and the peelable lid is peeled away from the base.
- the base is held proximate the texture, which provides a grippable surface proximate the exterior surface of the base.
- the base is squeezed proximate the texture thus deflecting the base inward to provide friction between the base and the solid product prior to inverting the base so that the solid product does not fall out of the base until the friction is released.
- the base is inverted so that the bottom of the base is in an upward orientation and the top of the base is in a downward orientation, and the texture enhances a user's ability to grip the base when the base is inverted. The friction is released thereby allowing the solid product to slide out of the cavity into the solid product dispenser.

- 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. 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.
