Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention Purpose of the Invention (Industrial Field of Application) This invention is particularly aimed at storing mushrooms that normally spread in all directions, such as Enoki mushrooms, in a bag made of resin or the like. This relates to a device for feeding items into bags in a bag filling and packaging machine that seals the opening of the bag.

(Problems to be solved by the prior art and the invention) Since this type of item spreads widely in all directions, it would be easier to put the item in if the opening of the bag was made larger to accommodate this. Since it cannot be made larger than necessary for transportation and storage, there is a limit to the size of the opening when opened.

Therefore, the present invention makes it easier to put items into the bag even when the opening of the bag is small.

Structure of the Invention (Means for Solving Problems) That is, the present invention is particularly applicable to the 22nd embodiment in the drawings of the embodiments described later.
