Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging material for a photographic filter.

[Prior art]

Traditionally, photography filters have come in various forms made of materials such as glass plates, gelatin membranes, and plastic films.For example, a glass plate filter is a filter in which a glass plate is assembled into a ring-shaped metal frame. When in use, this frame is attached and placed at the front of the lens barrel of a camera, etc. Since this glass plate filter is usually incorporated into a "frame", it can be supported by this frame and stored in a packaging container, and the filter can be placed in a predetermined position by attaching the frame to the mounting part of the imaging equipment. be able to.

On the other hand, photographic filters such as gelatin membranes and plastic films are generally not placed in the above-mentioned "frame", and therefore inevitably require a "holder" to hold the filter. After supporting it in the camera, it is attached to the lens shade and placed in front of the camera lens.

[Problem that the invention attempts to solve]

As described above, photographic filters such as gelatin membranes and plastic films require a filter holder, which poses a problem in that the user must purchase the holder separately along with the filter. Also, as a holder, the thickness and size (aperture) of the filters vary, so you have to select and purchase the one that matches the filter, and there is a problem in that it costs money to purchase the holder separately from the filter. It was hot.

[Means and actions for solving problems]

The present invention was devised to solve the problems in the prior art as described above, and by forming a holder for the filter from a part of the filter packaging material, it is possible to use and handle this type of filter. The purpose of the present invention is to provide a novel packaging material for a photographic filter that can simplify the process and improve cost savings. That is, the present invention provides a packaging material for a photographic filter that includes at least an exterior packaging bag and a bifold filter protection material that is housed in the packaging bag and that encloses and protects a film-like filter. A notch that can be cut into a predetermined shape is provided approximately at the center of each fold, and the filter protective material becomes a filter holder that holds the filter after the notch is cut out. This is a packaging material for a photographic filter, and is characterized in that an adhesive layer is provided on the inner surface of the filter protective material, and the outer surface of the filter protective material is black.

The present invention will be explained in detail below.

The packaging material for a photographic filter according to the present invention basically consists of an outer wrapping bag and a filter protection material. The filter protection material is housed in the former outer wrapping bag, and is a sheet-like body folded in two that encloses and protects the filter, and is made of cardboard, plastic sheet, or the like having a certain degree of bending strength. Therefore, the filter enclosed in the protective material is protected by the protective material from external forces such as folding or bending. What is unique about this invention is that the central part of each side of the filter protective material folded in half has a predetermined shape, and preferably, when the protective material is folded in half, the openings on both sides match. The shape has a cutout that allows it to be cut out.
FIGS. 1a and 1b are perspective views showing an example of a filter protection material of the present invention. In the example shown in figure a, each side 1-1 of the protective material 1 folded in half,
1-2 is a square, and cuts 2-1 and 2-2 are made in the center of each surface so that it can be cut into a circle. After the cuts 2-1 and 2-2 are cut out, the remaining parts can form a holder for holding the filter 3, as shown in Figure b. The filter protection material can be folded in half as shown above, and each side can be square or rectangular.
It may also be a polygon such as a pentagon or a hexagon,
Furthermore, as shown in FIGS. 2a and 2b, the shape may be circular (Figure A), elliptical (Figure B), or the like. However, the outer shape of the filter protector is determined depending on the shape of the loading tool used to place it in front of the camera lens, and is usually folded in half so that each side is square or rectangular. A protruding handle portion may be provided as desired. Further, an adhesive layer may be applied to the inner surface of the filter protective material in advance, and a release paper may be placed on the inner surface during packaging to cover and protect the filter. In particular, it is desirable that the outer surface of the filter protective material be black so as not to reflect light when used as a filter holder. The cuts made in the filter protection material may be dotted lines (perforations) as shown in FIG. It may be a cut made all around the circumference. However, the latter is preferable to the former because the cut portion is minute, easy to cut, and the cut end is clean. The shape of the notch may be circular with a diameter matching the aperture of the camera used, or may be of various shapes to obtain different photographic effects.

The outer wrapping bag of the packaging material of the present invention has the form of, for example, a box or a bag, and can house a filter and its protective material. These outer wrapping bags are made of various thick and thin papers, plastic films,
It is made from various film and sheet materials such as paper/plastic laminated film, aluminum foil/paper laminated film, aluminum foil/plastic laminated film, aluminum foil/paper/plastic laminated film, etc. The trademark, product number, performance, manufacturer's name, etc. of the filter to be accommodated may be printed on the front surface of the bag, or a label containing these information may be affixed.

The filter housed in the packaging material of the present invention is a film-like filter made of plastic film or gelatin film, and its shape, thickness, filter characteristics, etc. are standardized in the industry, but usually its size is 10cm x 10cm, 7.5cm x 7.5
cm. However, the packaging material according to the invention is not limited to packaging specifically adapted to these standards, but can also accommodate any other type of film filter.

A desired filter is housed in the packaging material of the present invention,
To package, first apply the specified filter film.
In order to protect the surface from damage, prevent it from sticking to the filter protective material, or maintain the surface cleanliness during handling, it may be covered with two sheets of paraffin paper, or sandwiched between two folded paraffin papers. It is also sandwiched between the filter protection materials that are characteristic of this invention, which is also folded in two. Then, the sandwiched and stacked items are stored in an exterior packaging bag and sealed. At this time, if desired, the filter may be sandwiched between protective materials to prevent moisture, etc., and placed in an inner bag made of polyethylene, for example, and this may be stored in the outer wrapping bag. Thereafter, the user of this filter opens the outer packaging, takes out the filter and its protective material, and applies adhesive to all or part of the inner surface of the unfolded filter protective material, or If it is, the user can peel off the release paper, sandwich the filter inside and apply pressure to stick and fix it, and the user has a film-like filter with a frame in their hands.

[Effect of idea]

According to the present invention, the packaging material for a photography filter can also be used as a holder for this filter, so there is no need to separately purchase or prepare a polder.
A useful effect of high convenience can be achieved.
