1. Pressure  Cookers for  Home Use  1 (1) The lid is able to be attached or removed from the cooker  smoothly.  (2) The cooker has a structure which leaks out steam when the  lid is not completely fitted to the cooker, and when the cooker is  heated under such conditions, the internal gauge pressure  (hereinafter referred to as the "Internal Pressure") does not  exceed 5.0 kilopascals.  (3) The cooker does not have a structure that directly applies  steam to the user to cause a burn due to a release of steam by  operation or activation of the depressurizing device and  pressure-adjusting device or leakage of steam when used  normally.  2 The cooker has a depressurizing device which releases steam  through manipulating a valve, etc. and has a structure which  does not let the lid open until after the Internal Pressure falls  below 5.0 kilopascals through such manipulation; provided,  however, that this does not apply in the following cases:  (1) In the case of a cooker whose lid is fitted to the cooker in the  form of a slide lid, the cooker has a structure whereby the lid  cannot be removed from the cooker when trying to slide the lid  by applying a force of 107.9 newtons to the tip of the handle,  where the Internal Pressure is 5.0 kilopascals and oil is applied  to the fitted part between the cooker and the lid.  (2) In the case of a cooker whose lid is fitted to the cooker in the  form of a drop lid, an over lid, or any other type of lid, the  cooker has a structure whereby the lid cannot be removed from  the cooker or the lid cannot be opened when trying to open the  lid by applying a force of 107.9 newtons, where the Internal  Pressure is 5.0 kilopascals.  3 (1) The handles are easy to hold, and they are joined to the  cooker or to the lid securely, or they can be easily and securely  joined to the cooker or to the lid.  (2) If the cooker is a single-handled cooker, it also has an  auxiliary handle.  4 The cooker is stable.  5 The cooker has no burr that could hurt the wearer's hand.  6 (1) The cooker has a pressure-adjusting device and a safety  device, and their nozzles are hard to clog and easy to clean.  (2) The weight of the pressure-adjusting device has a structure  that is hard to detach.  (3) The safety device has a structure that does not directly pop  out of the cooker when activated.  7 (1) The pressure-adjusting device is activated smoothly.  (2) Where the pressure-adjusting device has been activated, the  maximum Internal Pressure (hereinafter referred to as the  "Maximum Working Pressure") of the pressure cooker is no  more than 147.1 kilopascals.  29
