Description

  The present invention is an improvement of tableware, and more specifically, a transparent soft silicone that can be easily attached and detached, can carry heated and heated tableware, and prevents water droplets from entering foods. The present invention relates to a resin cover.

  In recent years, an aging society has progressed, and in welfare facilities such as nursing homes for the elderly, the number of residents has increased and the burden on care workers has increased, so to reduce the burden on care workers In addition, meal delivery services are becoming popular.

  By the way, the conventional meal delivery service has delivered cooked food materials to welfare facilities and reheated them in the cooking room of the facility. The delivery service using the cook chill method, in which food materials are delivered in a rapidly refrigerated state and then reheated after serving, has been the focus.

  In this cook chill method, food materials are generally housed in tableware, covered and heated with a cover lid. When cooking food materials, it is heated with cooking heat of about 200 ° C. Heat resistance is required. In addition, residents of welfare facilities that receive meal delivery services are likely to be elderly and have difficulty in handling their hands, so a silicone resin with high tack and heat resistance is used for the cover. The

However, silicone resin has good tackiness, but when used as a cover for tableware, when the heated food material cools, the pressure inside the tableware decreases and the cover is absorbed by the tableware due to negative pressure. There was a problem that it was difficult to remove. Conventionally, in order to make it easier to remove the covered lid made of an adsorbed silicone resin, there has been disclosed a cover provided with a turning piece (see Patent Document 1), but the lid is removed for elderly people who are handicapped. There is dissatisfaction that it is difficult.
As another conventional technique, food in a container is heated, and when the internal pressure rises and the lid is displaced upward, the inside and outside of the container ventilate to balance the pressure to facilitate the removal of the lid. There are structures (see Patent Document 2) and structures (see Patent Document 3) that facilitate the removal by balancing the pressure by opening a vent hole on the top of the cover lid and discharging the steam. There is a risk of water droplets entering from the through hole.
