Definitions
- the present invention relates to a lid opening device that opens a lid of an object to be opened such as a can or a bottle, and in particular, covers such as a screw lid type can or bottle that can be closed by screwing a lid into a screw groove.
- the present invention relates to a lid opening device having a rotating lid opening function for rotating and opening a lid of a lid, a can lid that is sealed by tightening and sealing, and a can opening function for opening the lid.
- Screw cap type cans and bottles that are often used as containers for a wide range of products such as food, beverages, and cosmetics that are screwed open and close are presumed to be opened manually. It is common to hold the part and pick the lid with the other hand and twist it in the opposite direction to open the lid. Most of these products are produced at the factory, and cans and bottles are closed with a machine, so they can be opened at the beginning, even if they are opened or unsealed. It is usually hard and difficult to open. However, since the lid part is relatively thin and small compared to the container part, even if the picking range is narrow, it is not possible to fully utilize the weak gripping force, making the opening more difficult.
- Patent Document 1 a lot of assistive tools during manual work have been proposed as shown in Patent Document 1, but in the case of a tightly closed lid, it is ergonomic to try to apply more force. It is difficult to hold the container vertically because the bottle or can is held in a tilted state, and it is difficult to hold the container vertically, especially when the contents are liquid or powdery products. There was also a bug.
