SUSTAINABLE TUBULAR CONTAINER FOR CONSUMER PRODUCTS
A sustainable tubular container that is fully recyclable by curbside recycling, repulpable and home compostable and is easy to use, prevents undesired leakage of the consumer product material, can withstand repetitive usage, and overcomes deficiencies of existing all paper consumer product container systems. The tubular container is primarily paper based that may be recycled easily in the existing paper recycling stream with minimal non-paper parts that also are easily biodegradable, recyclable curbside or home compostable. Such a consumer product container preferably is made of paper-based materials with an inner liner or a coating and otherwise, it is made of PHA, PHB and/or other compostable moldable materials.
This application claims the benefit of priority to U.S. provisional application no. 63/700,273 filed Sep. 27, 2024; and U.S. provisional application No. 63/685,165 filed Aug. 20, 2024, both of which are incorporated herein by reference in their entirety.
BACKGROUNDThe present invention relates to a sustainable tubular container for storing various types of contents, including consumer products such as toothpaste, lotions, balms, and sunscreen, and, more specifically, a tubular container for consumer products manufactured from primarily paper fiber material and in part from Polyhydroxyalkanoates (PHA), Polyhydroxybutyrate (PHB), or other similar biocompostable materials that can be injection molded or otherwise moldable and home compostable. The weight of the paper fiber material component is such that it is repulpable and recyclable. The PHA parts are fully compostable and comprise a smaller percentage by weight of the tubular container. This combination of paper parts and smaller percentage by weight of PHA parts gives the container of the present invention a unique sustainability profile. It means that the container can be both recyclable and home compostable, and far simpler to manufacture than existing containers intended to be sustainable. If the entire container was made entirely of PHA then it would be compostable, but it would be too expensive to be commercially practical.
Polyhydroxyalkanoates or PHAs are polyesters produced in nature by numerous microorganisms, including through bacterial fermentation of sugars or lipids. When produced by bacteria they serve as both a source of energy and as a carbon store. More than 150 different monomers can be combined within this family to give materials with extremely different properties. These materials are biodegradable.
Previous designs of all paper tubular containers for consumer products proved to be less than optimally for their intended use, too expensive, and difficult to manufacture. The new design of the tubular container in accordance with an embodiment of the present invention has some parts that are made of PHA, PHB, or other biocompostable material that can be injection molded and some parts that are made of paper. The weight of the paper fiber material is such that it is considered repulpable and recyclable.
It is appreciated that PHA is technically not a plastic or a bioplastic; although some might call it that because of its moldability properties. PHA is created by microbes so it is a moldable bio-based material that can be molded like plastic, but it is microbial in origin. PHA is desirable not only for its sustainability, but also for its durability for repeated use. It is intended to be within the scope of the present invention, that the small parts of the container be made of PHA, PHB, or other similar moldable material that is biocompostable.
The packaging of common consumer products such as toothpaste, lotions, balms, and sunscreen is primarily composed of plastic materials, which are challenging to recycle. Previous attempts at creating tubular containers for consumer products out of recyclable materials have faced issues, including properly avoiding leakage of the product material from the container and being airtight to preserve freshness of contents.
A key aspect of recycling fiber materials is the requirement to pass repulpability standards, such as those set by Western Michigan University (WMU) or the Fibre Box Association. These repulpability standards ensure that paper-based products can be efficiently broken down into their original fibers during the recycling process. The repulpability standards assess whether a material can disintegrate into a pulp without leaving behind any large, unrecyclable fragments or contaminants that could hinder the recycling process. To be recyclable in the paper recycling stream, at least 80% by weight of the entire package must be recoverable fibers through the repulping process. This means that the PHA parts must be less than 20% of the total package weight.
There is a need for a tubular container that is fully recyclable by curbside recycling, repulpable and home compostable. There is also a need for a tubular container that is easy to use, prevents undesired leakage of the consumer product material, can withstand repetitive usage, and overcomes deficiencies of existing all paper consumer product container systems. More specifically, there is a need for a tubular container that is primarily paper based that may be recycled easily in the existing paper recycling stream with minimal non-paper parts that also are easily biodegradable, recyclable curbside or home compostable. Such a consumer product container preferably is made of paper fiber material with an inner liner or a coating. But otherwise, it is made of PHA, PHB and/or other compostable moldable materials.
While the present invention in one embodiment relates to a tubular container for consumer products manufactured from primarily paper fiber material and in part from PHA, PHB, or other compostable moldable materials, it is appreciated that other embodiments of the present invention are being contemplated. For example, in another embodiment of the present invention, a tubular container for consumer products is made entirely of paper fiber material that is fully recyclable, easy to use, prevents leakage of the consumer product material, can withstand repetitive usage, and overcomes deficiencies of existing consumer container systems. More specifically, there is a need for a container that is a paper-based tube that may be recycled easily in the existing paper recycling stream. Such a tubular container preferably is made of paper fiber material with an inner liner or a coating. But otherwise, it is entirely made of paper fiber material including all aspects of the cap assembly.
For each embodiment described herein, the configuration of the tubular container could be scaled to any size suitable for the intended purpose. The cap structure could be of various shapes and sizes such as circular, square or rectangular for example.
SUMMARYThe present invention is directed to a tubular container for consumer products manufactured from sustainable materials that can be both recyclable and home compostable. In one embodiment, the container has a tubular body portion with a dispensing top end and an opposite sealed bottom end. The top end includes an opening and provides access to a hollow interior for storing the consumer product material. The top end can be closed with a removable cap to protect the contents of the hollow interior, prevent content leakage from the container, and preserve freshness of contents. The hollow interior of the container is fillable with the consumer product. The consumer product is dispensed towards the opening at the top end of the container with the cap removed by the application of pressure to the exterior of the container such as would be applied when squeezing a tube of toothpaste or a tube containing a lotion such as sunscreen.
In an embodiment, the materials of the tubular container can be both recyclable and home compostable, and are not required to be separated from one another to be recycled in the mainstream. Materials are manufactured from primarily paper fiber and in part from PHA, PHB, or other similar biocompostable materials that can be injection molded or otherwise moldable. The weight of the paper fiber material component is such that it is repulpable and recyclable. The PHA parts are fully compostable and comprise a smaller percentage by weight of the tubular container. PHA is desirable not only for its sustainability, but also for its durability for repeated use. This combination of paper fiber material parts and smaller percentage by weight of PHA parts gives the tubular container of the present invention a unique sustainability profile. It means that the tubular container can be both recyclable and home compostable, and far simpler to manufacture than existing containers intended to be sustainable. If the entire container was made all out of PHA then it would be compostable but would be too expensive to be commercially practical.
In another embodiment, the materials of the tubular container, including all aspects of the cap assembly, are made entirely from paper fiber material that is recyclable and repulpable. Materials used include, for example wound paper fiber, cardboard, corrugated cardboard, and cellulose with at least a portion of the materials preferably being made from postconsumer paper. The paper materials may include a lining or coating to prevent absorption by the components and/or leakage of the consumer product material from the container.
This embodiment of the present invention was specifically designed to ensure the repulpability of the packaging. The weight of the cap assembly and the selection of materials are carefully balanced to ensure that the entire package is repulpable, regardless of the type of liner used. By meeting these stringent standards, the tubular container enhances the efficiency and effectiveness of fiber recycling, supporting a more sustainable and recyclable packaging solution for consumer products.
