This invention relates to improvements in car
tons and packages.
~ It is the primary object of the invention to pro
vide a satisfactory carton and package for the
opening of the carton in a manner which will not
break the foil wrapper. Other objects of the in
vention will be more apparent from the follow
ing disclosure thereof.
