Description

The present invention relates to a pallet-shaped base frame for transporting and storing liquids, and to a transport and storage container equipped with the base frame. The base frame has a base, corner legs, and intermediate legs that support an internal container housed in a metal outer jacket, preferably a cage. A pallet-shaped base frame for transport and storage containers is known from Patent Document 1. This base frame has a base that supports the internal container of the transport and storage container, and the base is connected to the base frame that forms the contact surface of the transport and storage container via corner legs and intermediate legs. Because all components of this known pallet-shaped base frame are made of metal, the base frame is characterized by outstanding stability. Furthermore, this known pallet-like base frame functions as a base frame for transport and storage containers, which have inner containers housed in outer jackets on the base of the base frame and can be stacked on top of each other in a laminated configuration. The tubular base frame allows for easy access to the space formed between the stacked transport and storage containers. However, while the particularly excellent durability of known base frames is especially effective in extending the lifespan of known pallet-type base frames, it can lead to increased wear when in contact with conveying equipment, which often takes the form of conveying rollers or conveying belts. To reduce this wear, there has been a shift towards using base frames made entirely of plastic, or base frames that have both plastic and metal components. This type of composite pallet is known from Patent Document 2, which features a metal base connected to a plastic base frame or runner via plastic corner and intermediate legs. The use of plastic allows for low-friction contact between the pallet-like base frame and the conveying system. However, known pallet-like base frames suffer from low strength due to the plastic material used. Furthermore, contact between the plastic material and the conveying device leads to wear due to friction, resulting in progressive wear when the pallet-like base frame is used in a conveying device. Additionally, the removed plastic material can undesirably contaminate the environment of the conveying device in forms such as microplastics.

Figures 1 through 14 together show a transport and storage container 10 for liquids equipped with a pallet-shaped base frame 11. The transport and storage container 10 comprises a plastic inner container 12 having four side walls 13, 14, 15, 16, a lower bottom surface 17, and an upper bottom surface 18; a closable filling neck 19 formed on the upper bottom surface 18; a dispensing port 20 formed at the lower part of the side wall 13 and having a tap fitting (plug fitting) 21; a metal outer jacket 23 which is a cage 22 configured to house the inner container 12; and the pallet-shaped base frame 11. The outer jacket 23 has an upper frame formwork (upper frame profile) 24 and a lower frame formwork (lower frame profile) 25 which is screwed to the pallet-shaped base frame 11. Figure 3 shows a bottom view of the base frame 11. The base frame 11 consists of a base 26 that supports the internal container 12 housed in the outer jacket 23, corner legs 27, intermediate legs 28, 29, 30, a central leg 31, two outer runners 32, an intermediate runner 33, and a base crossbeam 34. In this example, the entire base frame 11 is made of metal. Figure 2 shows an assembly module 35 without the base 26.
