you have the bottle fitted around it
They place the bottle over the immature fruit and wait for it to mature.
In the spring when the buds of the pears start to break, these bottles are placed over the buds so the pears grow in the bottle
First ..the bottle has a short neck ... then you put the bottle over the "young" pear, lash the bottle down to the tree and wait for the pear to grow
Bottles are suspended over the pear buds (upside down) before they get too big (the buds not the bottle), and the pear grows in the bottle. I have been very successful in doing that for the last ten...
