Vacuum Insulated Food Jar MKL-W040/W050/W075 To be released on September 1, 2025

Tiger Corporation (President: Yoshisato Kikuchi, Headquarters: Kadoma City, Osaka) (“Tiger” or “we”), a world leader in thermal control technology, will release the Vacuum Insulated Food Jars MKL-W040/W050/W075 on Monday, September 1, 2025.

The recent high cost of living has increased the need for boxed lunches. The newly released Vacuum Insulated Food Jars MKL-W040/W050/W075 come in three sizes that can be used for a wide range of menus, from classic soups such as minestrone, to side dishes such as mapo tofu and arrabbiata, noodles like udon and fried noodles, and desserts such as yogurt and ice cream. This vacuum insulated food jar is ideal for lunchtime at work or school, as its vacuum-insulated structure keeps food hot or cold for a long time.

This is the first vacuum insulated food jar that uses Stopper with the integrated gasket, the stopper that forms part of the gasket, and is dishwasher-safe. Daily cleaning of this product is easy.

In addition, the rim boasts both the cleanliness and pleasant drinking experience of stainless steel. The upper part of the rim was curled to reproduce the mouth feel of a mug.

We will continue to refine our proprietary technology cultivated in our history of over 100 years to provide high-quality products to the world so that our customers’ daily lives will be further enriched by Tiger Corporation’s vacuum insulation technology.
