Food storage containers

Abstract

This product is a food storage container. As shown in [Reference Figure 1 showing the state of use] and [Reference Figure 2 showing the state of use], the food storage container of this product consists of a lid and a container. The food storage container is equipped with a vacuum pump (not shown) built into the lid, a battery, and a pressure sensor. The food storage container is used by operating the vacuum pump with the lid and container assembled to expel air from inside the food storage container and create a vacuum inside. The food storage container can maintain a vacuum inside by detecting the internal pressure with the pressure sensor and automatically operating the vacuum pump when the vacuum level decreases. As shown in [Reference Figure 3 showing the state of use], in the food storage container, the lid is equipped with a substantially cylindrical lid body and a substantially cylindrical handle located in the center of the top surface of the lid body. The lid is equipped with a power switch and indicator located on the top surface of the lid body, and a charging port and ventilation hole formed on the rear side of the lid body. The food storage container allows the user to activate a vacuum pump by operating a power switch (e.g., pressing it once), which allows the internal air to be exhausted to the outside through a vent. This increases the vacuum level inside the food storage container, creating a vacuum state. The food storage container also allows the user to draw air into the container by operating the power switch (e.g., pressing and holding it), thereby releasing the vacuum state. The power switch also serves as an indicator of the vacuum level inside the food storage container; when the user presses the power switch once, the power switch lights up green if the inside is in a vacuum state, and white if the inside is not in a vacuum state. The food storage container is further equipped with a cover that opens and closes the charging port. The cover is made of elastic resin, and the user can peel off the cover to expose the charging port to the outside. The food storage container can be charged by plugging a charging cable into the charging port, which allows the battery built into the lid to be charged. The indicator consists of three lights. One light illuminates when the battery level is below 30%, two lights illuminate when it is between 30% and 60%, and all three lights illuminate when it is 60% or higher, indicating the battery's charge status.As shown in [Reference Figure 3 illustrating the usage state], the food storage container is equipped with a hook formed on its outer surface. A measuring spoon used for taking out and measuring food (e.g., coffee beans, etc.) from the food storage container can be hung on the hook. An arc-shaped recess is formed on the upper edge of the hook, conforming to the shape of the measuring spoon.
