ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method of preparing a carton, such as a gift box. More particularly, the present invention relates to a method of preparing a carton, such as a gift box, with a prefolded interior paper lining, such as prefolded tissue paper.
2. Description of the Related Art
High end retail stores typically provide their customers with gift boxes. Typically, these boxes are in the form of partially folded carton blanks, which either the store clerk can assemble, or which can be provided to the customer for later assembly at home.
Customers frequently desire an interior paper lining, such as tissue paper, in order to improve the appearance of the gift box. For the sake of efficiency, attempts have been made to prepare carton blanks with prefolded tissue paper already inside, so that once the box is assembled, the tissue paper is already inserted and neatly folded.
These related attempts to prepare boxes with prefolded paper lining have been generally unsuccessful. The tissue paper frequently is torn or crumpled during the preparation process. Another problem is that the creases of the tissue paper generally correspond to the creases of the box blank, which typically results in the paper being crumpled upon assembly of the box. Finally, fixing the paper to the carton blanks creates problems for customers who do not desire tissue paper inside the box, because removal of the paper is difficult and leaves unsightly bits of paper and glue in the box.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to a method of preparing a carton with a prefolded interior paper lining, that substantially overcomes one or more of the problems caused by the limitations and disadvantages of related methods. The method of the present invention will provide cartons with a prefolded interior paper lining which, when assembled, will have a neater appearance, a much lower incidence of unusable cartons due to torn and crumpled paper, and consequently a lower overall cost.
Additional advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The advantages of the invention will be realized and attained by the process and apparatus particularly pointed out in the written description and claims, as well as the enclosed drawings.
To achieve these and other advantages, and in accordance with the purposes of the invention, as embodied and broadly described, the invention relates to a method and apparatus of preparing a carton with a prefolded interior paper lining. A box feeder feeds a carton blank in a first direction, the carton blank having a base surface, the base surface having leading and trailing end edges, and first and second side edges, the carton blank base surface further having a first length between the leading and trailing end edges, and a first width between the first and second side edges. Simultaneously, a paper feeding apparatus feeds a paper web under tension. The paper web is folded by a folding apparatus to have at least a base portion, and a first side flap, the first side flap joining the base portion at a first crease, and an opposite edge, the base portion of the paper having a second width between the first crease and opposite edge that is less than the first width of the carton blank base surface. A paper section is cut off of the paper web by a cutting apparatus, the paper section thereby having, in addition to the base portion, the first side flap, and the first crease, leading and trailing edges and a second length between the leading and trailing edges. The paper section is inserted with the carton blank such that the first crease and opposite edge of the base portion of the paper section are spaced a preselected distance inward from the first and second side edges of the carton blank.
Preferably a line of adhesive, preferably a non-permanent, release-type adhesive, is applied to a selected position on the surface of the carton blank. However, in certain cases, the adhesive may be omitted.
When adhesive is used, the paper section is affixed to the carton blank by pressing the base portion of the paper section against the line of adhesive on the carton blank.
In another embodiment, the paper folding apparatus performs an additional step of folding the side flap of the paper into first and second subflaps, joined together by a crease.
The apparatus and method of the invention further may include a step of folding flaps of the carton blank inward over the inserted prefolded paper section.
Variations to the invention are possible. These variations may include varying the dimensions of the carton blank, utilizing a paper web with different dimensions, utilizing multiple paper webs, varying box or carton styles, varying a rate of paper feed, increasing a number of cutting blades in the cutting step, varying types of adhesive application, wetting the paper web, and so on. The paper also may be provided with additional folds, flaps, and subflaps as desired.
