ABSTRACT:

TECHNICAL FIELD
The present invention relates to packages, especially relates to packages having simultaneous opening structure of inner and outer wrapping layers of packages comprised of multi-ply wrapping layers.
BACKGROUND OF INVENTION
Cigarettes are generally sold in two types of packs. One type of pack is the so-called “soft pack” in which a group of cigarettes is wrapped in foil wrapper and the foil wrapper is in turn wrapped by a flexible paper wrapper. The second type of pack is a relatively stiff paperboard box having a hinged lid and sometimes referred to as a FLIP TOP ® box.
Both types of packs are typically airtightly circumscribed by a layer of generally transparent, nonporous film of a polymeric material such as polyethylene to maintain cigarette freshness.
By far, when desiring to open said packs of cigarettes, the smoker must manually tear off the upper part of the inner foil wrapper, which has always been unavoidable, tedious and inconvenient task for all the smokers.
DESCRIPTION OF PRIOR ARTS
In the prior arts such as the U.S. Pat. Nos. 1,516,455, 1,785,639, 2,123,262, 2,268,970, 2,330,150, 2,342,240, 2,415,117, 2,522,868, 2,588,996, 2,593,778, 2,675,169, 2,844,298, 4,465,185, 4,589,545, etc., there have been numerous devices, articles, and proposals to conveniently open the inner and outer wrapper and to expose the contents of a package.
However, in use, all these prior arts require the smokers to inevitably go through two steps to open the packs, e.g., first tearing off the tear tape, and second manual removal of some part of the wrappers.
Further, in manufacturing, what is far more important is the possibility to commercialize the invention in light of economy and usefulness.
In this light, as all these prior arts require additional part(s) in manufacturing and two stages in use the articles of the prior arts have serious drawbacks in the inventions themselves and in actuality all these inventions are only devised in vain.
In short, till now, there has been no structure or package which enables the smoker to simultaneously open the inner and outer wrapper of cigarette packs in a single motion of “only pulling the tear tape or lid”.
Further, there has also not been any outer wrappers nor webs of outer wrapper which have above said structures for cigarette packages.
OBJECTS OF THE INVENTION
Thus, it is an object of the invention to provide cigarette packs having structures which enable the smoker to simultaneously open the inner and outer wrapper of cigarette packs in a single motion of pulling the tear tape or opening the lid
A further object is to provide cigarette packs having simultaneous opening structures which, in manufacturing, require no additional parts, changes of processes, machineries or product lines, or rise of cost.
Still a further object is to provide inner and outer wrappers which have means to form opening structure in combination with other components for cigarette packs.
Still a further object is to provide a continuous web of outer wrapping sheet for cigarette packs having means for simultaneous opening structure.
Still a further object is to provide a method for making a continuous web of outer wrapping sheet for cigarette packs.
