[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The packaging material for sterilization of the present invention is a long packaging material for sterilization in which a peelable adhesive portion is formed near both side edges of a pair of front and back sheets, and at least one of the pair of front and back sheets includes It is characterized in that display units arranged at equal intervals are provided. The display portions arranged at equal intervals are a pattern formed by printing, a concave portion and / or a convex portion in a stacking direction of two sheets formed by embossing, and a side formed by notching a side edge. A concave portion at the end, a convex portion, and the like,
One of these may be used, or two or more thereof may be combined.

There are no particular restrictions on the shape of the pattern formed by printing, and examples include dots, lines, lattice patterns, pictures such as animals and marks, numbers, characters, shades of color, changes in hue, and the like. One of these may be selected and used, or two or more thereof may be combined. Here, as the ink used for printing, by using an ink having an indicating function, which changes color irreversibly when sterilization is performed,
This is preferable because mistakes in sterilization work can be prevented. As such an ink, as a coloring material that senses a temperature that becomes an indicator of steam sterilization, it is encapsulated in a dye or a thermosensitive microcapsule used for a thermosensitive recording material such as a diazonium salt compound, and when a predetermined temperature is reached. A coloring material that develops color by impairing the hermeticity of the microcapsules is exemplified. Commercially available products include, for example, Nescos IC (S-25B, high-pressure steam sterilization) manufactured by ICCS Center (Sakura Crepas). Inks used for thermolabels and steam integrator cards manufactured by NOF Engineering Co., Ltd. As a substance that senses EOG, for example, a composition having a dispersible dye having an (AN = NB) structure described in JP-A-5-1252 can be mentioned.・ CS Center (Sakura Crepas)
Nescos IC (EO-36, for EO gas sterilization) manufactured by Nippon Giken Kogyo Co., Ltd.
L and the like. In addition, examples of those that sense plasma include triphenylmethane-based dyes and cyanine-based dyes described in JP-A-11-178904.

In the case where the display section is formed of ink having such an indicator function, it is preferable from the viewpoint of visibility that at least one sheet is transparent, and that printing is performed on one of the sheets. When performing the printing, printing on the outer surface is preferable from the viewpoint of the sensitivity of the indicating function. This display unit is formed at a predetermined interval,
The interval may be appropriately selected depending on the display accuracy of the target length. In general, the display portions are formed at equal intervals in the side edge direction. In addition, the display portions are formed at equal intervals in the width direction, or are formed at equal intervals in the side edge direction. In addition, forming oblique equal-spaced lines having a predetermined angle from the side end is also a preferable mode for securing linearity in the width direction.

[0010] In addition, the display portion by the above-mentioned embossing can be easily formed by using a predetermined embossing pattern at the time of laminating two sheets or by post-processing after lamination. The shape and interval of the concavo-convex pattern formed in the laminating direction of the two sheets formed by embossing may be selected and formed from the same viewpoint as the formation by printing.

[0011] In a third aspect, a concave portion at a side edge end,
In the method in which the convex portion is provided by cutting, the concave portion and the convex portion may be formed on both side ends, or may be formed only on one side end. The shape of the concave portion or the convex portion is also arbitrary, for example, I-shaped, V-shaped,
A notch such as a U-shape or a base may be provided at regular intervals as a mark. Since the concave portion or convex portion formed by these notches also has a function as an opening start notch, this also has an advantage that opening the opening is easy when tearing open.

A concave notch (recess) provided at a side edge of only one of the sheets, which is a fourth mode of the display unit, is a modification of the third mode. The tabs are formed in such a manner that the tabs are stacked with the sheet having no notch. That is, by providing such concave notches at regular intervals, it becomes a measure of the length, and since such a packaging bag is generally formed such that the side edge adhesive portion is peelable. In the case of peeling and opening, it has a function as a knob to facilitate opening start. In this case, by providing the adhesive portions on both side edges inside the sheet end portion and leaving the unadhered portions on the side edges, the knob portions are formed on both sheets, which further facilitates opening. Becomes

The shape of such a concave cutout is arbitrary as long as it is suitable for handling with a finger, and may be triangular or square. However, the presence of the arc-shaped portion makes it easier to grip the sheet. In addition, there are advantages that the smaller the number of corners, the easier the formation of the concave portion, that is, the easier the punch for forming the concave portion is. In addition, if the shape is acute, stress concentration occurs at the time of peeling, and there is a concern that only the sheet having the cutout portion is torn and the opening cannot be performed properly. Therefore, it is preferable that the shape has a smooth shape including an arc. In particular, the concave portion is formed by a U having a combination of an arc and a straight portion.
When the packaging material for sterilization of the present invention is manufactured in a multi-cavity form from a wide raw material by forming the shape into a letter shape, even if the position of the slit is slightly shifted, the angle of the concave portion does not become an acute angle, so the deviation is conspicuous. It is also preferable because the corners are less likely to accidentally be opened by touching other articles or injure a finger.

The set of front and back sheets constituting the sterilizing packaging bag of the present invention is not particularly limited, as long as it has a region capable of being sterilized and has a necessary strength, a known sheet-like material. Anything can be used. Here, the region that can be sterilized is usually sterilized by using high-temperature steam, ethylene oxide gas (EOG), plasma, or the like. It refers to a region made of a material that does not allow bacteria to permeate, and it is necessary to have such a region at least in part. The use of such a sheet may be either one or both, but the visibility of the contents is ensured by using one of a sheet made of gas-permeable paper or nonwoven fabric and the other as a transparent synthetic resin sheet. This is preferred.

Among the above sterilization treatments, the sterilization apparatus is simple in consideration of sterilization in a hospital, and EOG sterilization is suitable because it is inexpensive. Paper or nonwoven fabric having a permeability in a range that does not allow bacteria to pass through is preferred. All of the packaging bags can be made of such a sterilizable material,
From a viewpoint of cost, strength, and visibility of the contents, it is also a preferable embodiment that one uses a gas permeable material such as paper or nonwoven fabric and the other uses a transparent synthetic resin sheet.

[0016] In the packaging bag which is releasably adhered, the materials of the front and back sheets may be the same or different. Adhesion between two sheets is achieved by using an easy-peel (easy peeling) adhesive, or when one of the sheets is a nonwoven fabric of a thermoplastic resin, the other sheet exhibits a suitable adhesive strength as a thermoplastic sheet. A known method such as directly laminating a synthetic resin sheet or laminating it with another sheet via a sealing layer made of a thermoplastic material, followed by heat sealing and bonding can be employed.

The packaging material for long sterilization according to the present invention comprises two sheets, the front and back sheets being laminated, and peelable adhesive portions provided near both side edges, and at least one of the sheets is provided with a display portion at regular intervals. Is supplied in the form of a roll. In a hospital or the like, one end of the bag can be adhered by heat sealing or the like, cut into a size corresponding to the contents with reference to the display portion, and the opening end can be sealed to easily create a sterilization bag. .

[0018]

According to the sterilizing packaging material of the present invention, a long sterilizing packaging material is cut into a predetermined length without using a measuring means such as a measure or a measuring device to produce a sterilizing bag. This has the effect of being excellent in handleability.
