Carriage release chip with key ring hole and variable injection molding technology

Abstract

Trolley release chip for unlocking shopping trolleys, characterized in that the chip is equipped with a key ring hole (1) having a diameter of 6.5 mm to enable easy attachment to a key ring or bag and to ensure quick and uncomplicated handling.

Description

[0001] The present invention relates to a trolley release chip intended for use in shopping trolleys. The chip is designed to be equipped with a key ring hole, which allows for easy attachment and handling. The chip can be attached to a key ring or a bag and can be easily removed via the key ring hole.

[0002] An innovative feature of this invention is the interchangeable insert technology in the injection mold used to manufacture the chip. This technology allows for the application of various designs and logos to the chip during the production process. The chip is produced using interchangeable injection molds, which enable designs or logos to be exchanged quickly and cost-effectively without requiring a new mold for each design. This ensures flexible and efficient manufacturing, which is particularly advantageous for personalized products or promotional items. Another noteworthy aspect of the invention is the variety of materials from which the chip can be manufactured. The chip can be produced from various materials, including: • ABS (Acrylonitrile Butadiene Styrene): A resistant and durable material that is well suited for the production of chips that need to be robust and abrasion-resistant. • Bioplastics: An environmentally friendly alternative that is ideal for sustainable products. This option supports environmentally conscious companies that value ecological materials. • Stainless steel (using laser cutting technology): The chip can also be made of high-quality stainless steel, employing precise laser cutting technology to produce the chip with high accuracy and robustness. Stainless steel offers high resistance to abrasion and corrosion and is particularly suitable for durable products.

[0003] The top of the chip offers ample space for the design shown, while the underside features a keyring hole. The keyring hole has a diameter that allows for secure attachment of the chip to a keyring or pocket. At the same time, it is designed so that the chip can be easily removed without accidentally coming loose.

[0004] The chip is made of high-quality, durable material that is both weather-resistant and abrasion-resistant. The material's robust properties ensure a long lifespan for the chip, even with frequent use. The chip's surface is smooth and resistant, so it won't wear down even with frequent use.

[0005] The combination of interchangeable insert technology in the injection mold and the key ring hole makes this trolley release chip particularly flexible and functional. It is suitable for a wide range of applications, especially in advertising and personalization, and offers a cost-effective solution for companies that want to display their brands or logos on shopping trolley chips.

[0006] An embodiment of the invention is described with reference to the Fig. 1 to 2 explained. They show: In Fig. Figure 1 (top view) shows the upper side of the chip (2), which acts as a trolley release and unlocks egg trolleys from all manufacturers. The oval recess (3) saves weight and material while also providing stability. The key ring hole (1) has a diameter of 6.5 mm. Fig. Figure 2 (view from a slant above) shows the rounded edges (5) and the interchangeable insertion area of ​​the injection mold (4).

[0007] The present invention enables the easy release of shopping carts using a universal cart release chip that is compatible with all shopping cart systems. The chip offers a practical and efficient solution for consumers to quickly unlock and freely move shopping carts. The invention thus opens up new possibilities for the use of cart release chips in everyday life and for companies that want to offer a user-friendly solution to simplify the shopping process.

[0008] Furthermore, the trolley release token offers versatility for advertising and personalization, as it can be customized with various designs, logos, and motifs. This adaptability makes the token an ideal promotional gift that is both practical and personalized. Rapid production, achieved through the use of interchangeable insert technology in the injection mold, enables cost-effective and swift manufacturing, allowing companies to quickly offer tailored solutions for their customers and promotional campaigns. Reference symbol list: 1 Keyring hole The hole on the trolley release chip allows for easy attachment to a keyring or pocket and uncomplicated removal of the chip. 2 Top surface of the chip The top surface of the chip on which the design, logo or motif can be printed, which is integrated using the interchangeable insert technique in the injection molding process. 3 Oval cutout The oval cutout inside the chip makes it more stable and lighter at the same time by reducing the amount of material used, but maintaining the required strength. 4 Interchangeable insert technology in the injection mold: The technique in which interchangeable injection molds are used to integrate different designs and logos onto the chip during the production process. 5 Rounded edges The rounded edges all around the chip ensure a pleasant feel.
