adhesive backing 30 on the other side for initial engagement with the container when the label is applied label 20 is depicted as rectangular in configuration and naturally it may assume other configurations as long as it is of sufficient size to extend both above and below the joint line 28 and be applied to both container half 24 and container half 26 it is not necessary that the label 20 extend around the entire circumference of the container it may cover only a portion of the container surface as depicted in the drawings label 20 is provided with a plurality of cuts such as die cuts or prescores 32 on its surface with the cuts 32 being divided into two groups one group is positioned on the label so that when the label is applied to a container they will be on one side of joint line 28 and the other group positioned so that they will be on the other side of joint line 28 thereby providing cuts 32 in alignment with each container half 24 and container half 26 while the cuts may take any reasonable configuration it has been found acceptable to use diagonal cuts as depicted in use container 22 is filled with the desired object such as a medical instrument and the two halves 24 and 26 are brought into engagement to form joint line 28 label 20 with cuts 32 therein and adhesive 30 on one side thereof is then applied to the container with the adhesive 30 engaging with the surface of container 22 so as to initially hold label 20 in position label 20 is positioned so that a portion including one group of cuts 32 is.
