[Problems to be solved by the invention]
  Such a sealed pack device is often used for the purpose of sealing food or the like in a bag. However, if the container of food or the like contains a liquid material or is in a powder form, the concave portion 42 is used. A part of the contents may spill out from the opening of the bag inserted into the bag. The spilled material accumulates at the bottom of the recess 42, contaminates the suction chamber 44, and lowers the hygiene condition. Alternatively, there is a problem that the air enters the suction pump in the body 41 through the deaeration port 47, impedes the function of the pump, and deteriorates the degree of decompression.
[0007]
  Further, since the suction chamber 44 is fixed by using the concave portion 42 on the upper surface of the container body 41, it is difficult to clean the interior of the container body 41 because operations such as washing and removal are directly performed on the container body 41. In addition, since the upper pad member on the upper lid 43 side is also attached to the back surface thereof, it is similarly contaminated and it is not easy to clean the portion. Therefore, such a conventional sealed pack device is required to have a function of easily cleaning and removing the convection and contamination of the contents that have entered the suction chamber 44.
[0008]
  Therefore, the present invention aims to provide a sealed pack device that satisfies such requirements and can easily clean and remove the contaminants that have entered the suction chamber during the sealing operation to keep the suction chamber clean. To do.
