This invention relates to a soap bar package where a primary package supports a secondary package. This invention more particularly relates to a package where the primary package fully envelops the soap bar and provides the support for the secondary package that facilitates orientation on a display shelf.
Soap bars are packaged in various ways. These include the use of paperboard cartons, plastic boxes, and paper and plastic wrapping. The objective is to protect the soap bar from contamination, maintain a given moisture content in the soap bar and to provide an acceptable appearance at the point of sale. In addition, the package also may provide for stability on the sales shelf so that the soap bars can be stacked several bars high and several bars deep on the shelf.
The present soap bar package is comprised of a primary package and a secondary package. The soap bar can be of any shape. The primary package surrounds and encloses the soap bar. The secondary package holds and contains one or more of the primary packages and holds these primary packages in an orientation so that along with the secondary package they can be self supporting on a store display shelf and also can be stacked on the store shelf. In addition, they can move readily be fitted into a shipping carton.
The primary package in one embodiment is comprised of a relatively stiff, self supporting material. This primary package material encloses the soap bar and has an outwardly extending peripheral edge. The peripheral edge extends outwardly so as to contact the inner surface of the secondary package. It can be in essentially any orientation with respect to the soap bar. However, in one embodiment this edge can be an extension of a plane through the longitudinal axis of the soap bar at an angle of 0 degrees to about 45 degrees to the lateral axis of the soap bar. In this orientation, the edges will be in a plane through the longitudinal axis to being in a plane about diagonally through the soap bar. The orientation, shape and dimension of this edge will be determined by the secondary package, the number of soap bars to be contained within the secondary package, and the end product rigidity of the secondary package.
The secondary package is comprised of a semi-rigid, to rigid material that when reinforced by the primary package can retain its shape as a package. This primary package can be anchored within the secondary package in various ways. In a preferred technique part of each contained primary package can protrude through a surface of the secondary package. This stabilizes the primary package within the secondary package and the primary package further reinforces the secondary package.
When the secondary package has such apertures the primary package need not have a peripheral edge adapted to reinforce the secondary package. Thus this peripheral edge can be of a reduced dimension so as not to contact the secondary package, or can be of a flexible material that would not substantially reinforce the secondary package.
The primary package and the secondary package can be constructed of various materials. These include paperboard, foils and plastics. Plastics are preferred for the primary package and paperboards for the secondary package. The plastics can be monolayers or laminates.
The present invention will be described in the preferred embodiments with reference to the drawings. Other embodiments which utilize the concept of a primary package and a secondary package, and in the instance where the primary package provides support for the secondary package in a similar manner are within the present concept.
As an alternative the portions 36 and 38 can be sealed together and then through an injection opening a soap bar composition in a liquid state added to the hollow cavity and the liquid soap bar composition set to a hardened soap bar. In this latter embodiment, the portions 36 and 38 sealed together will have an opening at either end for the injection of the liquid soap composition. This opening is sealed after the injection of the liquid soap composition.
The edges 32 and 34 can be an extension of a plane through the longitudinal axis of the soap bar and package. This plane also can be through the lateral axis of the soap bar or at an angle of up to 90 degrees to the lateral axis, and preferably up to about 45 degrees to the lateral axis. The positioning of the edges would be to optimize the reinforcing of the secondary package.
An optional embodiment is where the primary package does not have a peripheral edge or has a flexible peripheral edge. In this instance the contact of the two soap bars with each other and with the interior wall of the secondary package, and the projecting through the walls of the secondary package will stabilize the primary packaged soap bars in the secondary package. A key feature in this embodiment is each primary packaged soap protruding through the walls of the secondary package.
The primary and secondary package can be constructed of a variety of materials. These include plastics, foils and paperboards. The secondary package preferably is a paperboard and the primary package, a plastic, and preferably a thermoformable plastic. The plastics can be monolayers or multi-layered laminates. The plastics can be transparent, translucent or opaque. They preferably are thermoplastics such as polyethylenes, polypropylenes or polyesters such as polyethylene terephthalate. They also can be copolymers of ethylene, propylene, butylene vinyl and vinylidene monomers such as vinyl alcohol, vinyl acetate, vinyl chloride, vinylidene chloride and copolymers of these polymers.
The primary package can be of a flexible to a semi-rigid to rigid material. Where it will reinforce the secondary package it will be a semi-rigid to rigid material. The secondary package will be of a semi-rigid material to a rigid material. A semi-rigid material is sufficient and will be a cost savings.
