BACKGROUND OF THE INVENTION
[0001] This invention relates to a package of a photographic photosensitive material, and a packaging apparatus and method therefore.
[0002] A photographic photosensitive material is packed into a light-shielding moistureproof bag to form an inner package of the photographic photosensitive material, and a stack of several inner packages are packed into a corrugated board box to complete a package of the photographic photosensitive material.
[0003] In the above package of the photographic photosensitive material, since a stack of the several inner packages was packed in the corrugated board box, it is necessary to produce corrugated board boxes having a variety of sizes according to the photographic photosensitive material to be packaged. Therefore, the packaging apparatus must be arranged so as to fit each corrugated board box having a different size, and the arrangement is very troublesome. In the past, several packaging techniques which can easily change the size of a box were proposed in Japanese Patent KOKAI No. 60-77809, Japanese Patent KOKAI No. 61-164903 and the like.
[0004] Besides, printing on a corrugated board box is usually printed on a corrugated board sheet prior to assembling the corrugated board box.
[0005] However, in the above-mentioned packaging art to be able to easily change size, a piece of board sheet is cut and bended to be formed in box-shape, so that works for changing size is troublesome and the packaging apparatus is complex, and it is difficult to provide a full automatic apparatus. Moreover, since the box is made of a piece of sheet, a space remains between an article to be packaged and the box opposed by the rectangular faces of the box. As a result the article can not packaged in a state fitted to the box.
[0006] Besides, since a printing is provided on the sheet, the sheet can not be used for the articles in various sizes and shapes in common. Therefore, there is no versatility in the sheet.
SUMMARY OF THE INVENTION
[0007] An object of the invention is to provide a package of a photographic photosensitive material which is easily changed in size and which can package an article in contact with a corrugated board box.

DETAILED DESCRIPTION OF THE INVENTION
[0015] The first paper board and the second paper board cover three faces of the articles to be packaged respectively, the articles are package in a box composed of the first paper board and the second paper board. The simplest package is composed of two paper board in "V"-shape. Both ends of the second paper board preferably projects from each end of the first paper board. Because, in the case that the both ends of the second paper board is in accord with the ends of the first paper board, when the second paper board curls to the outside, the article is exposed. However, in the case that both ends of the second paper board project from the ends of the first paper board, even if the second paper board curls to the outside, the article is not exposed.
[0016] When the second paper board overlaps with the first paper board, the overlapping part of the paper boards is joined by adhesive. While, when the second paper board does not overlap with the first paper board, the paper boards are joined by adhesive tape.
[0017] When the paper boards are simply joined at one or two points, the box composed of the paper boards is collapsed to be easily flat, therefore disposability is very excellent.
[0019] The article to be packaged includes an inner package of a roll of a photographic photosensitive material, sheets of a photographic photosensitive material and the like, and a stack of two or more thereof.
[0021] In the package of a photographic photosensitive material of the invention, the first paper board and the second paper board respectively cover at least three faces of the article to be packaged to protect the article from the outside pressure, and the form in box-shape is kept by joining of the first paper board and the paper board.
[0022] In the packaging apparatus of the invention the furst creasing cutting means makes the first paper board of a paper board sheet, and the wrapping means makes the furst paper board to wrap the article. The second creasing cutting means makes the second paper board of a paper board sheet, and the second wrapping means makes the second paper board to wrap the article wrapped with the first paper board. The joining means joins the first paper board to the second paper boards wrapping the article.
[0023] In the packaging process of the invention, the printing is conducted after wrapping the article to be packaged with two pieces of paper board and therefore, the paper board sheet is used freely.
[0024] In the present invention, an article to be packaged is packaged by two pieces of paper board and therefore, articles having arious sizes and shapes are easily packaged by changing the size and shape of the paper boards. Moreover, since the article is in contact with the paper boards, the protection of the article is increased. Besides, in the present invention, printing is conducted on the face of, at least, one paper board after joining both paper boards together. Therefore, it is not necessary that printing is conducted on the paper board prior to wrapping the article with the paper board, and the same paper board can be used for articles having various sizes and shapes. As a result, the paper board has generality.
