DEFINITION

Classification: 229/200

Having means to facilitate opening the box by severing (e.g., tearing, cutting, piercing, etc.) box material or outer wrapper:

(under subclass 100) Box which includes means that expedite or enable parting of box material or flaccid exterior covering to gain access to the box interior to insert or remove content.

(1) Note. The "means to facilitate opening" may include one or more of the following: (a) an inherent characteristic of the box material (e.g., grain direction), or (b) a weakening of the box material (e.g., a score line), or (c) an additional element (e.g., a tear string).

(2) Note. Tearing is defined as failure of the box material by tension at a line of separation.
