Abstract
Official abstract text for this publication.
An improvement is made in a package including a protective film enclosing an article and a tack label coupled to an outer surface of the protective film such that a step of forming a slit in the protective film can be omitted and the need to form a dent at a specific area in the article is eliminated. A protective film includes an overlapping portion in which a first edge portion directly opposing the article and a second edge portion opposing the article via the first edge portion are overlapped with each other, and in a coupling surface between a tack label coupled so as to cover the overlapping portion and a protective film, a non-uniform coupling force distribution is provided in which a second region continuously connected to the second edge portion has a higher coupling force than a first region continuously connected to the first edge portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A package comprising a protective film enclosing an article and a tack label coupled to an outer surface of the protective film, wherein the protective film includes an overlapping portion in which a first edge portion directly opposing the article and a second edge portion opposing the article via the first edge portion are overlapped with each other, the tack label is coupled so as to cover the overlapping portion, a coupling surface between the protective film and the tack label is divided into a first region continuously connected to the first edge portion and a second region continuously connected to the second edge portion, a non-uniform coupling force distribution in which the second region has a higher coupling force than the first region is provided on the coupling surface, and an auxiliary adhesive portion having a higher coupling force than the first region is provided extending in the shape of a strip between two portions of the first region. 2. The package according to claim 1 , wherein an extension portion extending radially outwardly from the edge of the article is provided on the first region side of the tack label such that the tack label is longer on the first region than on the second region side. 3. The package according to claim 1 , wherein the second edge portion is coupled to the first edge portion by electrostatic sealing. 4. The package according to claim 1 , wherein a perforated line extending along the first edge portion is provided in the first region of the protective film.
