Abstract

A product packaging for a solid product comprises 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.

Description

  The present invention relates to product packaging for solid products.

  Solid products offer many advantages over using non-solid products. For example, solid products are usually prepared as concentrates and are usually less expensive to transport because they are designed to be diluted before use. Solid products can be prepared with aggressive chemicals that provide better cleaning, including strong acids and bases. Because solid products do not spill like non-solid or liquid products, solid products containing such aggressive chemicals are usually safer than comparable non-solid or liquid products. It is thought that there is.

  The solid product is dispensed into a solid product distributor to create a concentrated use solution or use solution. Some solid products are caustic or corrosive and should not be handled in direct contact with the solid product. This is especially true in industrial laundry, dishwashing, and floor care products.

  Thermoformed blister packs and lidded containers are commonly used to package solid products. However, these types of packaging usually require the user to remove the backing or lid from the container and drop the solid product into the dispenser. This method exposes the user to direct contact with the solid product, which is undesirable.

  Another type of packaging in which solid products are packaged is shrink wrap film. Small holes in the film allow for the exhaustion of air that would otherwise be trapped when the film shrinks and conforms to the shape of the solid product. These small pores allow moisture to enter the package from the atmosphere, which can cause the solid product to swell and at least partially dissolve. In addition, the user may be in direct contact with the solid product leaking from these small holes. Thus, it is interesting to charge the solid product into the distributor without touching the solid product.

  One challenge with respect to the manufacture, storage and use of solid products, including extruded acidic and alkaline solid products, is the stability of the solid product. When exposed to environmental conditions such as moisture, the solid product may absorb moisture and cause softening or dissolution of at least a portion of the solid product. Moisture absorption can result in a softened layer of solid product, making it difficult to handle and properly distribute the solid product. In addition, at higher humidity or higher alkali concentration conditions, moisture absorption can lead to the formation of a liquid product that can sink or flow out of the surface of the solid product, creating a puddle of highly caustic material. There is. Moisture and solid product stability are not the only issues in the manufacture and handling of the product, but unstable properties can also cause problems in the distribution of the product. A softened surface or liquid material can flow out of the surface, causing the material to fluctuate during distribution, which can result in distribution at non-uniform concentrations. When dispensed using a spray-type dispenser, the water spray is directed onto the surface of the solid product. When properly operated, this spray removes a small portion of the solid product in the form of an aqueous concentrate of the working solution. If the solid product is at least partially softened or liquefied, the aqueous concentrate of the use solution becomes too concentrated.

  It would be desirable to have a solid product packaging that contributes to charging the solid product without direct contact with the solid product, and that contributes to keeping the solid product stable during storage of the solid product.

  One aspect of the present invention provides a product packaging for a solid product that includes a base, a lid and a seal. The base has a top surface, side surfaces, and a bottom that form a cavity configured and arranged to receive a solid product, and the base has an outer surface. The texture on the outer surface of the base increases the user's ability to grip the base when the base is inverted. The seal interconnects the top surface of the base and the lid and allows the lid to peel from the top surface of the base.

  Another aspect of the invention provides a method for dispensing a solid product from a product package into a solid product dispenser. A product package having a base, a lid and a seal is obtained. The base has a top surface, side surfaces, and a bottom that form a cavity configured and arranged to receive a solid product. The seal interconnects the top surface of the base and the lid and also allows the lid to be grasped and peeled so that the lid can be separated from the top surface of the base. A portion of the peelable lid is gripped and the peelable lid is peeled from the base. The base is held and turned upside down so that the bottom of the base is in the up direction and the top surface of the base is in the down direction. The solid product can slide out of the cavity into the solid product distributor.

  Another aspect of the invention provides a method for dispensing a solid product from a product package into a solid product dispenser. The product packaging has a base, a lid and a seal. The base has a top surface, side surfaces, and a bottom that form a cavity configured and arranged to receive a solid product, and the base has a textured outer surface on at least a portion of the outer surface. . The seal interconnects the top surface of the base and the lid and also allows the lid to be grasped and peeled so that the lid can be separated from the top surface of the base. Product packaging is obtained. A portion of the peelable lid is gripped and the peelable lid is peeled from the base. The base is gripped near the texture, which provides a surface that can be gripped near the outer surface of the base. The base is squeezed in the vicinity of the texture, and the base is distorted inward to give friction between the base and the solid product before the base is turned upside down. Do not fall from. The base is turned upside down and the bottom of the base is in the up direction, and the top surface of the base is in the down direction, and texture enhances the user's ability to grip the base when the base is turned upside down. The friction is then released and the solid product can be slid out of the cavity into the solid product distributor.

  The present invention contributes to charging a solid product without touching the solid product directly, and also contributing to keeping the solid product stable during storage of the solid product, and the solid product from the product packaging to the solid Gives a way to dispense into the product distributor.
