Is there any video about how to make a paper cup as shown in the picture?(Chloroform inhalation in partial hanging)

Case report
A 31 year old man used chloroform inhalation in partial hanging.He used an apparatus shown in the picture.

I am thinking about doing the same way. I will inhale chloroform vapours until I pass out when my head in the noose. My body will put pressure in my neck when I go unconscious

Is there any video shown how to make a cup shown as in the picture? Or can you describe it somehow?

Any idea is appreciated.

Thanks
