Collapsible Barrel

Description

BACKGROUND OF THE INVENTION

Traditional barrels utilized for storage and transportation are typically rigid and occupy significant space, even when empty. These conventional barrels, often constructed from materials such as metal or rigid plastic, do not permit compact storage when not in use. This results in inefficient use of storage space and increased transportation costs, as empty barrels occupy the same volume as filled ones.

There is an escalating need for a more efficient solution to these limitations. A collapsible barrel, which can be conveniently stored and transported when not in use, would substantially reduce storage space requirements and transportation costs. Additionally, such a barrel must be durable, lightweight, and easy to handle to meet the demands of various industries, including agriculture, manufacturing, retail, and logistics.

The present invention addresses these needs by introducing a collapsible corrugated plastic barrel. This barrel is engineered to collapse inwardly towards its base, thereby facilitating compact storage and easy transportation. Fabricated from high-density polyethylene (HDPE), the barrel is both durable and lightweight. The corrugated design of the barrel provides additional rigidity when in use, while the flexible nature of the material allows for easy collapsing. The barrel also includes a detachable lid and locking mechanisms to secure the contents during storage and transport.

TECHNICAL FIELD OF INVENTION

The present invention pertains to the field of collapsible containers, and more specifically, to a collapsible corrugated plastic barrel designed for the efficient storage, packing, and transportation of various goods.

Prior Art

Collapsible containers made from various materials, including corrugated plastic, are well-known in the industry. Traditional collapsible corrugated boxes and cartons, typically made of paperboard, feature vertical side walls and top and bottom flaps for forming closures. These containers often incorporate score lines or hinge lines to facilitate folding and unfolding.

Several patents disclose collapsible containers made from corrugated plastic. For instance, U.S. Pat. No. 6,102,279, describes a collapsible corrugated plastic box with improved hinge line configurations and handholds. This invention provides a plastic box that can be easily collapsed for return shipment and reuse. Another example, U.S. Pat. No. 6,257,484, discloses a collapsible corrugated plastic box with tear-resistant handholds, enhancing the durability and usability of the container.

While these prior art references offer valuable insights into the design and functionality of collapsible corrugated plastic containers, they do not address the specific needs and features of a collapsible corrugated plastic barrel as described in the present invention. The current invention offers a unique combination of features, including a cylindrical body with a corrugated structure for enhanced rigidity, a base portion, a top portion, and a detachable lid.

The design allows the barrel to collapse inward.

BRIEF SUMMARY OF THE INVENTION

The present invention pertains to a collapsible corrugated plastic barrel designed for the efficient storage, packing, and transportation of various goods. This barrel comprises a cylindrical body constructed from corrugated plastic, a base portion, a top portion, and a detachable lid. The corrugated structure allows the barrel to collapse inwardly towards the base for compact storage when not in use, significantly reducing storage space and transportation costs. Fabricated from high-density polyethylene (HDPE), the barrel provides durability, impact resistance, and chemical resistance. The design includes features such as stackability, forklift entry points, and ergonomic corrugation for easy handling. The barrel is also recyclable and exempt from ISPM 15 regulations, making it an environmentally friendly solution for various industries.

DETAILED DESCRIPTION INVENTION

The present invention pertains to a collapsible corrugated plastic barrel designed for the efficient storage, packing, and transportation of various goods. The barrel is constructed from high-density polyethylene (HDPE), providing durability, impact resistance, and chemical resistance. It features a cylindrical body with a corrugated structure, a base portion, a top portion, and a detachable lid.

Construction/Manufacturing the Barrel:

1. Base Portion:

• • The base portion is molded from HDPE using structural foam molding techniques to ensure strength and durability. It serves as the foundation of the barrel and includes forklift entry points for easy handling and transport.

2. Cylindrical Body:

• • The cylindrical body is formed with a corrugated structure to provide enhanced rigidity and flexibility. The corrugation allows the body to collapse inwardly towards the base, significantly reducing storage space when not in use. The cylindrical body is connected to the base portion and the top portion via hinge mechanisms.

3. Top Portion:

• • The top portion is also molded from HDPE and is designed to engage securely with the upper edges of the cylindrical body. It provides structural integrity to the barrel when in the expanded position.

4. Locking Mechanisms:

• • Locking mechanisms are incorporated to secure the barrel in its expanded position during use. These mechanisms ensure stability and maintain the barrel's shape during the storage and transportation of goods.

5. Detachable Lid:

• • The detachable lid is designed to fit securely over the top portion, protecting the contents within the barrel. The lid can be easily removed and reattached, providing convenient access to the stored goods.

Operation:

1. Expanding the Barrel:

• • To use the barrel, expand the cylindrical body from its collapsed state by pulling the top portion upward until the hinge mechanisms lock into place. This action transforms the barrel into its full height, ready for filling.

2. Filling the Barrel:

• • The expanded barrel can be filled with various goods to the desired height, ensuring even distribution to maintain stability. The corrugated structure provides the necessary rigidity to support the contents.

3. Securing the Lid:

• • Once filled, the detachable lid is placed over the top portion and secured using the locking mechanisms in the form of a circular ring. This ensures that the contents are protected during storage and transportation.

4. Collapsing the Barret:

• • When the barrel is empty, remove the lid and disengage the locking mechanisms. Push the top portion downward, allowing the cylindrical body to collapse inwardly towards the base. This compact configuration significantly reduces the storage space required for the empty barrel.

Additional Features:

1. Stackability:

• • The design allows multiple barrels to be stacked securely, optimizing storage and transportation efficiency.

2. Ergonomic Corrugation:

• • The corrugated design provides a comfortable grip for manual handling, making it easier to move and transport the barrel.

2. Environmental and Safety Considerations:

• • The barrel is made from 100% recyclable HDPE polymers, contributing to environmental sustainability. It is also exempt from ISPM 15 regulations, ensuring it is hygienic and easily sanitized.

By following these construction and operational steps, the collapsible corrugated plastic barrel provides a practical and efficient solution for the storage and transportation of goods across various industries. The innovative design enhances both operational efficiency and environmental sustainability.
