In principle, it is not allowed. Registered trademarks can only be used on the approved goods or services. Your trademark is still unregistered on the goods. If you use a registered trademark on the box lunch, it is suspected of impersonating a registered trademark, which may also infringe on the trademark rights of others. However, you can use it as an ordinary trademark for the time being, and don't use the R mark of the registered trademark on the box lunch. If you want to use it on your own goods for a long time, it is recommended to register this commodity category.
