Description

Description: TECHNICAL FIELD The present invention relates to a container of a photosensitive strip material such as a rolled photographic paper or a photographic film, and more specifically, under sunlight and indoors. The present invention relates to a photosensitive strip material container provided with a teremp cloth at the outlet for loading the photosensitive strip material under the certification light.

[Conventional technology]

There are various types of light-shielding containers for strip-shaped photographic light-sensitive materials. For example, Japanese Utility Model Publication No. 53-20934 and Japanese Utility Model Publication 55-88980.
JP, JP-B-55-113543, JP-B-43-7575, JP-B-59-36736, U.S. Pat.No. 4148395, U.S. Pat.No. 4,179,028, U.S. Pat.No. 4272035. It is disclosed in a book or the like. 551-1135
Japanese Patent Laid-Open No. 43-43 proposes a container for belt-shaped photographic light-sensitive material, in which the belt-shaped photographic light-sensitive material wound in a roll shape is protected from light and can be easily loaded into the apparatus under room light.

That is, in this container, a slit-shaped outlet for drawing out the belt-shaped photographic photosensitive material is formed in a magazine formed in a light-shielding manner, and a foam pad or a felt pad is provided at this outlet for ensuring light-shielding property. . Then, the strip-shaped photographic light-sensitive material wound in a roll shape is housed inside.

As described above, in a portion of the light-shielding container for belt-shaped photographic light-sensitive material where the belt-shaped photographic light-sensitive material is drawn out, a light-shielding member is generally used for the purpose of preventing light from entering the light-shielding container and exposing the belt-shaped photographic light-sensitive material inside the container. Is provided. Although there are various types of light-shielding members, the one mainly made of cloth is called a "temperp cloth". Although this telemp cloth is expensive, it is widely used because it has the advantage that scratches are unlikely to occur on the surface of the strip-shaped photographic light-sensitive material, unlike the foam pads.

Conventionally, as such a telemp cloth, there is one in which a schematic view of a side section is shown in FIG. 9 (Jitsuko Sho-46-20539).
Issue). This telemp cloth is formed by weaving a pile yarn 4 into a base cloth 1 having a woven structure. Cloth 1 is the 10th
As shown in the schematic plan view of the drawing, the warp yarns 2 and the weft yarns are woven, and the pile yarns 4 are coreless obtained by crimping a flexible original yarn such as viscose or acetate. Pile thread is used. Then, the base cloth 1 is impregnated with a pile thread 4 and a sealing adhesive 5 for fixing the base cloth 1. In order to produce such a teremp cloth, the weft yarns 2 and 3 are woven on a flat ground, and at the same time, the pile warp yarns 4 are woven into a double velvet and cut into a substantially uniform pile length. Is common.

Further, as another conventional telemp cloth, there is a cloth as shown in FIG. 11 which is a schematic view of a side section (Japanese Patent Laid-Open No. 54-36).
No. 924 publication). This telem cloth has an electrostatic flocking structure and is formed by electrostatically flocking short fibers 7 by providing an adhesive layer 5 on a container base 6 made of metal or the like.

Further, there is also a technique of directly bristling the thermoplastic resin forming the outlet of the container to secure the light shielding property of the outlet (JP-A-57-190948).

And, these telemp cloths are formed to have a substantially uniform thickness, that is, the piles located on the outer surface are formed to have substantially the same length, and the piles on the outer surface are in contact with each other so that the light shielding property can be secured. It was provided on the tongue and lower tongue.

[Problems to be solved by the invention]

By the way, the telem cloth has not only a light-shielding function to secure the light-shielding property in the light-shielding container but also a flexibility so as not to damage the strip-shaped photosensitive material when the strip-shaped photosensitive material is pulled out or rewound. , It is necessary to prevent yarn scraps from adhering to the surface of the strip-shaped photosensitive material and to prevent failure, that is, to prevent hair loss (pile loss) and to have a pile orientation so that the strip-shaped photosensitive material does not meander. is there.

However, in the case of a so-called woven structure light-shielding telem cloth, which is also called a velvet weave or a velvet weave, which is obtained by weaving the pile threads shown in FIG. (Pile missing)
In addition, the production process is complicated and the production cost is high, and even when the strip-shaped photosensitive material is pulled out or rolled into the light-shielding container for the strip-shaped photosensitive material, friction or peeling (pile) occurs due to friction with the surface of the strip-shaped photosensitive material. There was a case where the scraps adhered to the photosensitive film of the strip-shaped photosensitive material and caused a trouble. Especially when it is used as the outlet of a light-shielding container for indoor light-loading roll color photographic paper, the photosensitive film using gelatin swells under high temperature and high humidity and the adhesiveness increases, so piles adhere to the photosensitive film, There was a problem in practice.

In addition, it is important to control the relationship between the slit opening width of the outlet and the length of the pile of the telemp cloth provided on the upper tongue and the lower tongue within a predetermined range in order to exert the function of the light-shielding container for the photosensitive strip. Is. However, conventionally, it has been very difficult to accurately control these lengths, and various problems have occurred.

That is, even if a container having a constant slit opening width is manufactured, if the length of the pile of the light-shielding telem cloth changes significantly, the pulling-out and unwinding resistance of the photosensitive strip material largely changes, and the length of the pile becomes long. In JIS135 type photographic film cartridge, the winding torque of the camera becomes large, and the perforations perforated on both sides of the photographic film are broken or the photographic film is cut and it becomes impossible to shoot. In addition, like a recent camera, a camera having a self-winding and unwinding mechanism has a large motor load and cannot be driven. Other roll film for phototypesetting, roll-shaped photographic paper, thermal paper,
Photosensitive roll film and roll paper for industrial materials,
Similar results are obtained in a light-shielding container for loading a strip-shaped photosensitive material such as a photosensitive resin roll film under sunlight and indoor light.

On the contrary, when the pile length is shortened, the above problem is solved, but it becomes impossible to secure the most important light shielding property as the light shielding container for the photosensitive material.

Even if the pile length of the light-shielding telem cloth can be always made uniform, it is very difficult to form the slit opening width of the outlet uniformly, and the slit opening width changes. For this reason, there is a problem in the light-shielding property, the winding property, and the unwinding property of the photosensitive strip material container. Generally, the slit opening width of the drawer of the photosensitive strip material container also varies depending on the length of the pile of light-shielding telem cloth applied to the upper tongue and the lower tongue of this slit opening, that is, the thickness of the telem cloth. It was impossible to keep the pullout resistance constant.

Also, in the case of the light-shielding telempe cloth with the electrostatic flocking structure shown in FIG. 11, the production process is slightly simplified, but since the tricot etc. is coated with an adhesive and then electric flocking is performed to fix the pile, the fixation The piles that are not adhered and the piles that are weakly adhered are too loose to be put into practical use.

The present invention has improved these problems of the prior art, and can completely maintain the light-shielding property even when the slit opening width of the drawing port is wide or the thickness of the telemp cloth is short, and it is possible to draw out the photosensitive strip and An object of the present invention is to provide a photosensitive strip material container which has a small rewinding resistance and is free from meandering and scratches.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention is to form a teremp cloth with a knitting structure, and to form a concave ridge portion and a convex ridge portion to be fitted in each of the teremp cloths.

That is, the photosensitive strip material container of the present invention is provided with a core on which the strip-shaped photosensitive material is wound in a roll shape, a drawer for drawing out the strip-shaped photosensitive material, and upper and lower tongues of the drawer and In a light-shielding container having a colored light-shielding telempic cloth, the light-shielding telempe cloth is formed by a knitting structure, and one of which has a concave line portion and the other of which has a convex shape that substantially fits into the concave line portion. A strip portion is formed, and the strip-shaped photosensitive material is characterized in that it is drawn out to the outside while bending between the recessed strip portion and the projected strip portion.

The light-shielding Telempu cloth provided on the upper tongue and the lower tongue of the outlet of the photosensitive strip material container of the present invention has the concave streak portion on one side and the convex streak portion on the other side. The concave streak and the convex streak are for substantially fitting state and preventing light from passing through the inside of the container when the telem cloth is provided on the upper tongue and the lower tongue. Therefore, if the light-shielding property can be ensured, the concave streak portion and the convex streak portion can be formed in various linear or curved shapes such as a rectangular shape, a triangular shape, and an arc shape. Further, the mating may be performed in a state in which they are in contact with each other or in a state in which the ridges are in the ridges with a gap.

It is sufficient that at least one set of the concave line portion and the convex line portion be formed, or they may be formed over several lines, or both may be formed on the same light-shielding telem cloth. Further, the concave stripes and the convex stripes need not be linear in the plan view, and may be formed in a V shape, for example.

Further, the pile length of the light-shielding telem cloth is appropriately determined by the shapes of the concave and convex portions.For example, in the case of a rectangular shape, the long pile is 0.8 mm or more and the short pile is 0.7 mm or more.
It is preferable that the length is at least 0.1 mm, that is, the length obtained by subtracting the length of the short pile from the length of the long pile is 0.1 mm or more.

The reason for this is that when these long piles and short piles are installed on the upper tongue and lower tongue, they will mesh with each other at a portion of 0.1 mm or more, so the light shielding property is secured even if there are variations in pile length and slit opening width. Because you can.

The light-shielding telemp cloth is formed of a loop pile, a fluff pile, or a pile in which these two are combined. The loop-shaped pile is a pile formed in a loop (wanna) shape, and the fluffy pile is a pile formed by opening the loop-shaped pile to form a fluff. These piles are colored to ensure photosensitivity. This coloring may be done with any dye or pigment as long as the light-shielding property can be secured, and the color thereof is not particularly limited, but black is preferable in order to more fully secure the light-shielding property.

From the viewpoint of preventing fraying of the cut surface, hair loss (pile loss), and pile thread goose that occurs during fiber opening (shearing), it is preferable to use loop-shaped piles for all, but the flexibility of the surface of the telem cloth , It is inferior to the opened fluffy pile in terms of light-shielding property, and the direction of the loop-shaped pile's teremp cloth is generated, so that when the strip-shaped photosensitive material is pulled out from or unwound from the slit opening, there are meandering and scratches. It tends to occur.

Therefore, loop pile 90 ~ 20% and fluff pile 10 ~
It is preferred that 80% of both piles be mixed and used in various ratios within the above range depending on the kind of the band-shaped photosensitive material. The arrangement of the loop pile and the fluffy pile on the light-shielding telem cloth is preferably performed so as to be in a uniform state according to the mixing ratio. In addition, the fluffy pile is formed taller than the looped pile, and the fluffy pile is located on the surface portion of the telem cloth, and the semi-cut pile in which there is both the fluffy pile and the looped pile in the middle and lower parts. This is preferable from the viewpoint of preventing hair loss (pile loss), improving flexibility, light-shielding property, and the like.

There are various methods for producing the light-shielding telempu cloth having such a structure, but in any of the methods, a loop-shaped pile is formed on the surface of a knitted fabric. Velvet made by weaving pile yarns into the woven fabric of Japanese Utility Model Publication No. 46-20539
In terms of quality such as hair loss, it is inferior to the light-shielding telempu cloth having a knitted structure, and is not suitable for the present invention.

As a first method for making a telem cloth having a loop-shaped pile, so-called horizontal knitting knitting such as circular knitting or flat knitting is raised into a loop-shaped pile.
g) There is a method of making a light-shielding Telempu cloth by raising a loop-shaped pile of the above-mentioned light-shielding Telempu cloth or so-called vertical knitting knitting such as tricot knitting, Russell knitting, and Milanese knitting.

Further, as a method for directly producing a knitted fabric having a loop-shaped pile without raising, there are a method using a circular knitting pile knitting machine, a method using a circular sock pile knitting machine, and the like. A sinker pile is a typical circular knit pile. (For details, see Textile Engineering Society, Journal of Textile Engineering vol.33, No.7 (1980) P390-3
97). Particularly preferred is a sinker pile type light-shielding telem cloth and tricot vertical knitted fabric, which is a knitted fabric having loop piles in a circular knitting machine, using fibers containing 50% or more of black-colored polyester fibers, acrylic fibers, and nylon fibers. This is a French pile type light-shielding telem cloth which is produced by using a machine to fabricate a knitted fabric and then hooking a thread running laterally with a needle and pulling it out into a loop to make a looped pile. For use as a light-shielding telempe cloth, a light-shielding telempe cloth in which 10 to 80% of the loop-shaped pile thus formed is cut and opened (shearing) and 90 to 20% is left as the loop-shaped pile is preferable. In addition, heat setting to prevent deformation of the shape of the light blocking telem cloth,
It is also possible to impregnate the base cloth with a sealing adhesive.

In the present invention, the fabric and pile of the light-shielding telem cloth are synthetic fibers made of a thermoplastic resin (nylon fiber, acrylic fiber, polyester fiber, vinylon fiber, vinyl chloride fiber, vinylidene copolymer fiber, polypropylene fiber,
Polyethylene fiber, polycarbonate fiber, etc.) can be used for melting and cutting so that the cut surface does not fray like the heat slit method or ultrasonic slit method. It is preferable because it has a good heat setting property afterward and is superior to natural fibers in various points such as a large Young's modulus and a large physical strength.

However, synthetic fibers, individual fibers such as rayon, acetate, cotton, silk and the like, specially processed fibers, fibers obtained by mixing and spinning two or more kinds, and the like can be selectively used depending on the required characteristics.

The above-mentioned light-shielding telem cloth is provided on the upper tongue and the lower tongue of the outlet of the light-shielding container of the strip-shaped photosensitive material. The belt-shaped photosensitive material includes all kinds of belt-shaped photosensitive materials such as color photographic paper, computer typesetting film, computer typesetting paper, JIS135 type photographic film (Leica film), thermal paper, photosensitive resin film and microfilm. The light-shielding container includes all containers having a structure in which a strip-shaped photosensitive material wound in a roll shape is housed in a core and the strip-shaped photosensitive material is drawn out from an outlet. For example, a light-shielding container for color photographic paper, a film cartridge, a light-shielding container for phototypesetting, a light-shielding container for microfilm, and the like.

In the present invention, there are various methods for providing the light-shielding telemp cloth on the container body, and any known method can also be used. For example, a method of applying various adhesives to the place where the telemp cloth is attached on the container body and then applying a light-shielding telempe cloth cut to a predetermined size, or a method of applying a sealing agent to the light-shielding telempe cloth and further applying a hot melt adhesive. There is a method in which it is cut to a predetermined size, placed at a sticking place, melted and reactivated by heat, ultrasonic waves, high frequency, or the like, and stuck. Further, there are methods such as a method of using a sealing adhesive that also serves as a sealing agent and an adhesive, a method of using a double-sided adhesive tape, and the like, and all known bonding methods are possible. The method of using the double-sided adhesive tape is often applied to the case where the container body is made of a material such as paperboard or corrugated board which is easily deformed and has low rigidity.

A preferred mode is one in which the foam sheet, the foam coating layer, or the elastic layer described in JP-A-59-201848 is provided between the container body and the light-shielding telem cloth. Particularly preferred is a method using a double-sided adhesive tape in which an adhesive is applied to both sides of the foamed sheet.

[Action]

In the photosensitive strip material container according to the present invention, since the light-shielding telem cloth is formed in a knitting structure, the pile has a structure in which the warp yarn of the base cloth is wound. Therefore, the strip-shaped photosensitive material will not be damaged without the pile thread coming off.

The light is blocked by the convex portion and does not enter the inside even if the light-blocking cloth is not contacted or strongly contacted. Further, the strip-shaped photosensitive material is not pressed by the light-shielding telem cloth, so that the pulling-out and rewinding work becomes smooth.

〔The invention's effect〕

Since the light-shielding telem cloth of the photosensitive strip material container of the present invention is formed with the concave portion and the convex portion that are fitted to each other, even if the tip ends of the piles of the upper and lower telem cloth are not in contact with each other at a predetermined density. The light is blocked on the way, and the light blocking property can be secured. Therefore, even if the width of the slit opening of the draw-out port is wide or the pile length of the telem cloth is short, the light-shielding property can always be ensured. Further, since it is possible to weaken or not to contact the upper and lower teletemp cloths in the range where the light-shielding property can be secured, it is possible to greatly reduce the pulling-out and rewinding resistance of the belt-shaped photosensitive material, and the The manufacturability is improved and the number of defective products is greatly reduced.

Also, since the light-shielding telem cloth is configured as a net,
The pile is formed integrally with the base fabric, and there is almost no pile cutting waste in the manufacturing process and processing process.
Further, even under high temperature and high humidity, there is almost no fraying, pile loss, or adhesion of pile cutting film on the surface of the photosensitive film of the belt-shaped photosensitive material which is in contact with the light-shielding cloth. Further, the pile can be removed without being impregnated with the sealing adhesive, and it can be attached to the light shielding container using only the double-sided adhesive data.

Furthermore, it is cheaper than the conventional velvet weave light-shielding cloth and the knitting speed is several times faster than the weaving speed, so that it can be efficiently manufactured.
