Description

Medical supplies storage container

The present invention relates to a medical supplies storage container to which a label in which a nonwoven sheet and an adhesive layer are laminated is attached and subjected to high-pressure steam sterilization.

医薬品 Medicines such as prefilled syringes and infusions, and medical supplies such as blood bags and catheters must be kept clean and sterile until use. Therefore, these medical supplies are stored in a resin container and sterilized in advance such as high-pressure steam sterilization in an autoclave. The storage container is affixed with a resin label via an adhesive layer informing the user of information such as the name of the medical supplies stored, the name of the manufacturer, and precautions.

During high-pressure steam sterilization, high-pressure steam causes shrinkage of resin labels and expansion of resin containers. Upon subsequent cooling, the container will shrink. At that time, the label becomes unable to follow the expansion and contraction of the storage container, and a wrinkle is generated, making it impossible to read the information on the label, and high-pressure steam enters from there and peels off.

In order to reduce the thermal shrinkage of the label, in Patent Document 1, medical device information is displayed on the surface of the sheet-like label body, and means for dispersing the stretching force applied to the label body that expands and contracts due to thermal deformation, for example, a slit is a label. A medical device label is disclosed in which a back surface of a label main body is attached to a sterilizable medical device provided on the main body. In this label, the width of the slit changes according to the contraction of the label, thereby preventing wrinkles on the label and peeling of the label from the medical device. It is troublesome to provide a slit in the label, resulting in an increase in manufacturing cost, and information such as characters and barcodes attached to the label is divided by the slit and is difficult to read. In addition, if the area of the label is increased, the influence of expansion and contraction increases, so that a large number of slits must be provided in accordance with the area, and the manufacturing cost increases further, and the number of divided parts such as letters increases. The attached information becomes more difficult to read.

JP 2004-8341 A

The present invention has been made to solve the above-described problems, and even when a label attached to a medical supplies storage container is exposed to a high-pressure steam atmosphere of high-pressure steam sterilization treatment, wrinkles or medical supplies are produced. It is an object of the present invention to provide a medical supplies storage container that can accurately read information described on a label without peeling from the storage container.

The medical supplies storage container of the present invention made to achieve the above object is surrounded by a bottom portion at a lower end, a peripheral wall portion continuous around the bottom portion and extending toward the upper end, and an upper end of the peripheral wall portion. A container body having medical openings selected from medical devices and pharmaceuticals, and a container body that has a flange extending from a peripheral edge of the opening, covers the opening, and is attached to the flange. A medical supplies storage container that has a protective film or protective lid that seals the main body and is subjected to high-pressure steam sterilization, and is composed of a continuous nonwoven sheet and an adhesive layer that are made of pulp as the main component. It is possible to maintain a state in which the label is attached to the outer wall surface of the peripheral wall portion following the deformation of the container via the adhesive layer.

It is preferable that the medical supplies storage container can maintain the state where the label is attached to the container body by allowing the nonwoven sheet to follow the deformation of the container that occurs during the high-pressure steam sterilization treatment.

In the medical supplies storage container, the pulp may be wood pulp, non-wood pulp, and / or waste paper pulp.

In the medical supplies storage container, the label preferably covers the nonwoven sheet with a hydrophilic resin protective film or contains a hydrophilic resin in the nonwoven sheet.

In the medical supplies storage container, the nonwoven sheet may be high-quality paper, medium-quality paper, kraft paper, kent paper, imitation paper, crepe paper, or Japanese paper.

In the medical supplies storage container, the nonwoven sheet preferably has a basis weight of 50 to 300 g / m ² .

In the medical supplies storage container, the nonwoven sheet preferably has a thickness of 20 to 200 μm.

In the medical supplies storage container, the adhesive layer may be made of an adhesive component containing acrylic resin, rubber, silicone resin, polyvinyl alcohol resin and / or starch paste.

The medical supplies storage container is a prefillable syringe in which the medical supplies have an injection needle having a syringe needle at a distal end portion and a flange at a proximal end portion, and a cap for sealing the distal end portion and the injection needle. The container body has a shelf on the inner wall of the peripheral wall portion, the shelf mounts a nesting plate, and the nesting plate engages with the flange to allow the prefillable syringe to be inserted and removed. It is preferable to have a plurality of receiving tubes suspended so as to be insertable into each other.

In the medical supplies storage container of the present invention, the label affixed to the container is a laminate of pulp, a nonwoven sheet and an adhesive layer as main components. And the medical supplies storage container is not peeled off, so that the described information can be read accurately. Moreover, since wrinkles are not generated, the area of the label can be increased.

It is a disassembled perspective view which shows an example of the medical supplies storage container to which this invention is applied. It is a model partial expanded sectional view which shows the state by which the label was stuck to the medical supplies storage container to which this invention is applied. It is a perspective view which shows another example of the medical supplies storage container to which this invention is applied.

Hereinafter, modes for carrying out the present invention will be described in detail, but the scope of the present invention is not limited to these modes.

1 is a perspective view of one embodiment of the medical supplies storage container 10 of the present invention. The medical supplies storage container 10 includes a resin container main body 30 having an upper surface opened, a resin nesting plate 40 having an outer dimension somewhat smaller than the inner dimension of the opening 33, and protection of the nonwoven fabric covering the opening 33. The film 60 and the label 20 attached to the container body 30 are included.

The container body 30 is a substantially rectangular parallelepiped having a bottom 31 at the lower end and a continuous peripheral wall 32 extending toward the upper end around the bottom 31 and surrounded by the upper end of the peripheral wall 32 to form an opening 33. The area of the bottom 31 is narrower than the area of the opening 33 because the peripheral wall 32 is narrowed. The outer wall surface of the peripheral wall portion 32 is smooth so that the label 20 can be adhered and attached easily. The flange 34 extends from the periphery of the opening 33 and surrounds it. The protective film 60 is affixed to the collar 34 to cover the opening 33 and seal the container body 30.

The nesting plate 40 has a substantially rectangular outer shape, and a plurality of receiving tubes 41 penetrating therethrough are arranged. The receiving tube 41 holds the flange 51 at its upper end and suspends and suspends the prefillable syringe 50. The syringe barrel 52 is fitted with a cap 53 for protecting the injection needle fixed to the tip thereof.

The nesting plate 40 is placed on a shelf 35 that protrudes from the inner wall surface of the peripheral wall portion 32 when the container body 30 is narrowed in the middle.

A substantially rectangular label 20 having a circular arc is attached to at least one of the outer wall surfaces of the peripheral wall portion 32. In FIG. 1, an example is shown in which labels 20 are respectively attached to two opposing outer wall surfaces so that they can be identified from multiple directions. FIG. 2 is a schematic partial enlarged cross-sectional view showing a state where the label 20 is attached to the outer wall surface of the peripheral wall portion 32. The label 20 displays information about the medical supplies storage container 10 and the medical supplies stored therein by displaying information about the medical supplies storage container 10 and the medical supplies stored therein. is there. The label 20 is configured by laminating a non-woven sheet 21 and an adhesive layer 22 formed on the lower surface thereof by application of an adhesive.

The nonwoven sheet 21 is a high-quality paper mainly composed of pulp made of cellulose fibers. The cellulose fibers constituting the fine paper are entangled with each other while having a gap on the order of micrometers, and form a fine porous material having non-woven and random fine porosity. Since the upper surface of the non-woven sheet 21 is not laminated or coated with a pigment or the like, the cellulose fibers are exposed. The adhesive layer 22 is formed by applying an adhesive to the lower surface of the nonwoven sheet 21. This pressure-sensitive adhesive penetrates and adheres to the fine pores formed on the surface of the non-woven sheet 21, so that no interfacial peeling occurs at the interface between the non-woven sheet 21 and the pressure-sensitive adhesive layer 22.

The pressure-sensitive adhesive composing the pressure-sensitive adhesive layer 22 can be quickly and affixed to the adherend by applying a slight pressure at room temperature without using a solvent or the like and without depending on heating. Later, it must not easily peel off from the adherend. Therefore, a pressure-sensitive acrylic pressure-sensitive adhesive is suitable. Acrylic pressure-sensitive adhesive is excellent in water resistance and heat resistance, so it is difficult to deteriorate even in a high-pressure steam atmosphere of high-pressure steam sterilization, and has good wettability with the peripheral wall portion 32, which is a resin. 20 is not easily peeled off. Specific examples of the acrylic pressure-sensitive adhesive include those having poly (meth) acrylic acid ester as a main component. Examples of poly (meth) acrylate esters include methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, methyl methacrylate, ethyl methacrylate, propyl methacrylate, and butyl methacrylate. Examples thereof include a homopolymer obtained by polymerizing a monomer selected from (meth) acrylic acid alkyl esters, and a copolymer obtained by copolymerizing any of them. In addition, at least one of these monomers and 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, 3-hydroxypropyl acrylate, 3-hydroxybutyl acrylate, 4-hydroxy acrylate Hydroxyl-containing (meth) acrylic such as butyl, 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate, 3-hydroxypropyl methacrylate, 3-hydroxybutyl methacrylate, 4-hydroxybutyl methacrylate Acid alkyl esters; (meth) acrylic acids such as acrylic acid and methacrylic acid; vinyl esters such as vinyl acetate and vinyl propionate; cyano group-containing compounds such as acrylonitrile and methacrylonitrile; amide groups such as acrylamide Compound; Ren, mention may be made of at least one copolymer of monomers selected from aromatic compounds such as vinyl pyridine.

During the high-pressure steam sterilization treatment, the high-pressure steam is absorbed in the fine pores formed by the cellulose fibers, enters the gaps between the cellulose fibers, breaks up the entanglement of the cellulose fibers, and the nonwoven sheet 21 is inflated to be stretchable. . The adhesive layer 22 changes from a cured state to a slightly softened state in a high-pressure steam atmosphere. The container body 30 expands in a high-pressure steam atmosphere. The non-woven sheet 21 follows the expansion of the container body 30, and the entanglement between the cellulose fibers becomes sparse, so that the non-woven sheet 21 extends flexibly. High-pressure steam easily enters between the nonwoven sheet 21 and the adhesive layer 22, but is not even partially peeled by the adhesive force of the adhesive layer 22 as the nonwoven sheet 21 softens. Moreover, the adhesion layer 22 buffers the difference between the degree of expansion of the container body 30 and the degree of elongation of the nonwoven sheet 21 by slight softening at high temperatures. As a result, the label 20 does not peel from the container body 30 even under a high-pressure steam atmosphere. Moreover, wrinkles on the surface of the nonwoven sheet 21 are not generated.

When sterilization is completed, the inside of the autoclave is cooled and then dried. Due to this cooling, the container body 30 contracts, and deformation may occur due to a difference in the degree of contraction based on a difference in shape, thickness, etc., at each part of the container body 30. The nonwoven sheet 21 follows the contraction of the container body 30 and contracts so that the cellulose fibers are intertwined closely. The pressure-sensitive adhesive layer 22 is gradually cured and contracts while being in close contact with the nonwoven sheet 21. As a result, the label 20 contracts substantially uniformly as compared with the case where the nonwoven sheet 21 and the adhesive layer 22 are not in close contact with the container body 30. The water vapor that has entered between the non-woven sheet 21 and the adhesive layer 22 is released from the fine pores formed by the cellulose fibers, so that it remains and partially peels off the adhesive layer 22 or softens the non-woven sheet 21. Don't let it go. In addition, the non-woven sheet 21 has a small gap between the cellulose fibers due to cooling and subsequent drying. As a result, the label 20 shrinks in accordance with the deformation while maintaining the state of being in close contact with the container main body 30, so that wrinkles are not generated or peeled off from the container main body 30.

Thus, since the label 20 has a structure that absorbs and releases water vapor, the nonwoven sheet 21 does not wrinkle even when exposed to a high-pressure steam atmosphere following the expansion / contraction of the container body 30. It does not peel from the interface between the nonwoven sheet 21 and the adhesive layer 22 or the container body 30. As a result, there is no problem in reading information such as written characters and bar codes. In particular, the barcode that must be accurately described does not deform, and can be read smoothly by a reading device.

The nonwoven sheet 21 that has absorbed water vapor is temporarily weakened and easily broken in an autoclave under a high-pressure steam atmosphere, but cannot be broken because it does not receive an external force such as a scratch. Since the cellulose sheet is exposed on the upper surface of the non-woven sheet 21, water vapor absorbed during sterilization can be released smoothly during cooling, and the strength is quickly recovered. For this reason, when taking out the medical supplies storage container 10 from the autoclave, it is not easily broken even if a force is applied to the label 20 by gripping it manually or by a conveying jig.

The thickness of the nonwoven sheet 21 is preferably 20 to 200 μm, more preferably 20 to 100 μm, and even more preferably 50 to 100 μm. If the thickness is less than this range, the strength is insufficient and the film tends to break. On the other hand, if it is thicker than this range, it will be too thick and the strength will be too great to follow the contraction of the container body 30. In addition, the water vapor absorbed when left to cool after sterilization is not released sufficiently and remains in the non-woven sheet 21 and becomes insufficiently dried. Therefore, the medical supplies storage container 10 is grasped together with the non-woven sheet 21 and lifted. When taking out from an autoclave, the nonwoven sheet 21 receives an external force and is rubbed and becomes easy to break or peel off easily. This thickness is calculated | required by the method based on JISP8118.

The volume of water vapor that the paper can absorb depends on the basis weight. Therefore, the non-woven sheet 21 is preferably 50 to 300 g / m ² within the above thickness range. When the basis weight is within this range, water vapor is smoothly absorbed and released, and it is difficult to cause wrinkles. If it is less than this range, the density of the cellulose fibers is lowered, and breakage easily occurs. On the other hand, when this range is exceeded, the cellulose fibers are in close contact with each other, the strength becomes too large, and the container body 30 cannot follow the contraction. This basis weight is calculated | required by the method based on JISP8124.

The label 20 does not generate wrinkles even if it is subjected to high-pressure steam sterilization, so that the area of the label 20 can be increased. Specifically, when one of the outer wall surfaces of the peripheral wall portion 32 shown in FIG. 1 is 5 to 10 cm long and 25 to 30 cm wide, the dimensions of the label 20 may be 4 to 8 cm long and 20 to 25 cm wide. it can. By enlarging the area of the label 20, a large number of large letters can be written or a blank space part can be provided so that it can be recognized even from a place away from the medical supplies storage container 10. You can write.

The label 20 contains information necessary for the medical product storage container 10 operator such as medical product name, manufacturer name, product name, quantity, expiration date, sterilization method, precautions, lot number, barcode, etc. Preprinted by printing. High-quality paper has good ink absorptivity, so it does not easily bleed even when printed or written, and a wide variety of types of writing instruments such as pencils and water-based / oil-based ink pens and inks used for printing can be selected.

In a state where the prefillable syringe 50 is inserted and suspended in all the receiving cylinders 41, a water vapor permeable and fine particle impermeable resin sheet is formed on the periphery of the upper surface of the container body 30 so as to cover the opening 33. A protective film 60 is attached or heat-sealed. The inside of the medical supplies storage container 10 is sealed. The protective film 60 may be a resin-made hard protective lid. The fine particles referred to here refer to bacteria and bacteria.

The medical supplies storage container 10 is manufactured as follows. First, the label 20 is manufactured. A roll-shaped raw material around which the non-woven sheet 21 is wound is set in a coating machine. While pulling the non-woven sheet 21 from this roll, a viscous acrylic resin adhesive is applied to one side thereof. As it is, it is sent to a tunnel-shaped dryer, and the solvent contained in the applied adhesive is evaporated to form the adhesive layer 22. A release material (not shown) is attached to the pressure-sensitive adhesive layer 22 and wound into a roll. Next, the label 20 is set in a printing machine for printing information, and the non-woven sheet 21 is pulled out from the roll, and desired information such as characters and barcodes is printed on the surface where the adhesive layer is not formed. . The label 20 is completed by cutting into a required size.

Next, the container body 30 and the nesting plate 40 are molded by injection molding. Medical thermoplastic resin pellets are put into an injection molding machine, and each is integrally molded. As shown in FIG. 1, the medical supplies storage container 10 is assembled, and the prefillable syringe 50 is suspended from all the receiving tubes 41, and then a protective film 60 is attached to the collar 34 so as to cover the opening 33. Then, the inside is sealed. The release material that covers and protects the adhesive layer 22 is peeled off and the label 20 is affixed to two opposing outer wall surfaces of the peripheral wall portion 32. The medical supplies storage container 10 whose inside is sealed is subjected to high-pressure steam sterilization in an autoclave. After sterilization, it is allowed to cool, taken out of the autoclave and dried. At this time, in the process from the sterilization process to the drying process, the label 20 is firmly attached to the container main body 30 and does not cause wrinkles and does not peel off. The medical supplies storage container 10 is packed and transported to a factory that fills the syringe with the medicine.

The medical supplies storage container 10 is used as follows. The medical supplies storage container 10 transported to the factory for filling the syringe with the medicine is subjected to a medicine filling process based on the information on the label 20. The medical supplies storage container 10 is placed in a predetermined position of a medicine filling device (not shown) with the protective film 60 peeled off in a clean room. A desired amount of medicine is filled in each prefillable syringe 50 from the medicine supply nozzle in the medical supplies storage container 10. The medicine is sealed in the syringe barrel 52 by a gasket inserted from the proximal end opening of the syringe barrel 52. The prefillable syringe 50 locked to the upper end of the receiving tube 41 is taken out from the medical supplies storage container 10, and after a pusher is attached to the gasket, it is inserted and sealed in an individually sterilized packaging bag. Stopped. The medical supplies storage container 10 is discarded as non-infectious waste with the label 20 attached.

FIG. 3 shows another example of the medical supplies storage container 10. FIG. 3 shows the medical supplies storage container 10 with the nesting plate 40 and the protective film 60 shown in FIG. 1 removed. Even if the label 20 is exposed to a high-pressure steam atmosphere, no wrinkles are generated and the label 20 is not peeled off from the container body 30, so that the area of the label 20 can be increased. Therefore, as shown in FIG. 3, the label 20 can be formed in a strip shape whose length in the longitudinal direction is substantially equal to the length that goes around all the surfaces of the peripheral wall portion 32. On the upper surface of the non-woven sheet 21, information such as the names of medical supplies to be stored is described in advance at positions corresponding to the respective surfaces of the peripheral wall portion 32. The label 20 is affixed so as to surround the four surfaces of the outer wall surface of the peripheral wall portion 32, so that the described information can be visually recognized from any direction. As a result, the medical supplies storage container 10 to which the protective film 60 is attached can be read without changing the viewpoint when stacked and moved during transport.

The nonwoven sheet 21 may be processed to impart strength with a water-resistant resin as necessary. For example, wet strength agents such as urea formaldehyde resin, melamine formaldehyde resin, polyamide polyamine epichlorohydrin resin, glyoxal modified polyacrylamide, polyamine epichlorohydrin resin or aliphatic dicarboxylic acid / polyalkylene polyamine / 2,3-epoxysulfonate resin It may be added to.

In order to prevent foreign matter from adhering to and mixing into the prefillable syringe 50 and the medicine filled therein, it is preferable that the nonwoven sheet 21 does not generate dust. The dust generation from the non-woven sheet 21 is caused by the dropped fibers and the pigment for coloring. Therefore, the non-woven sheet 21 is preferably composed of long-fiber pulp that does not easily fall off, and does not contain any pigment. The nonwoven sheet 21 may be impregnated with an acrylic resin emulsion or the like to suppress dust generation. In this case, the resin to be impregnated is preferably 1 to 30% by weight of the nonwoven sheet 21 so as not to block all the fine pores formed by the cellulose fibers.

After the protective film 60 covers the opening 33 and the inside of the medical supplies storage container 10 is sealed in order to prevent foreign matter from adhering to and mixing in the medicine stored in the prefillable syringe 50 or the syringe barrel 52, After the label 20 is pasted and subjected to high-pressure steam sterilization, a plastic film covering the label 20 may be pasted. The plastic film does not shrink because it is not exposed to high-pressure steam. Thereby, the dust generation of the non-woven sheet 21 can be suppressed, and the adhesion / mixing of foreign matters to the medicine stored in the prefillable syringe 50 or the syringe barrel 52 can be prevented.

In FIG. 1, the non-woven sheet 21 is a high-quality paper, but other than this, a medium-quality paper, craft paper, Kent paper, imitation paper, crepe paper, Japanese paper, or the like may be used. These raw materials are any one of wood pulp such as pulp made from softwood and pulp made from hardwood, non-wood pulp such as Mitsumata, Walla, Bagasse, Yoshi, Kenaf, Mulberry, and waste paper pulp. Alternatively, a plurality of them may be mixed and formed. In particular, wood pulp made from softwood is preferred because of its long fibers. When the fibers are long, there are many places where one fiber is entangled with other fibers, and the bonds between the fibers are strengthened to improve the strength. In addition, the amount of dust generated when the short fibers fall off is reduced.

The nonwoven sheet 21 may be covered with a hydrophilic resin protective film or may contain a hydrophilic resin. When it is covered with a hydrophilic resin or contains a hydrophilic resin, dust generation due to the falling off of the cellulose fibers can be suppressed without impairing the property of absorbing and releasing the water vapor of the nonwoven sheet 21. Examples of such hydrophilic resins include polyvinyl alcohol derivatives such as polyvinyl alcohol, carboxy-modified polyvinyl alcohol, and silanol-modified polyvinyl alcohol; cellulose derivatives such as methyl cellulose, hydroxyethyl cellulose, and carboxymethyl cellulose; starch, cationized starch, oxidized starch, Examples include starch derivatives such as grafted starch; resins having an ether bond such as polyethylene oxide, polyethylene glycol, and polyvinyl ether.

In FIG. 1, an acrylic pressure-sensitive adhesive is shown as the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer 22, but a rubber-based pressure-sensitive adhesive, a silicone-based pressure-sensitive adhesive, a polyvinyl alcohol resin, and / or starch glue may also be used. Examples of rubber-based adhesives include natural rubber, nitrile rubber, butadiene rubber, isoprene rubber, styrene-butadiene rubber, and styrene-isoprene rubber. The rubber-based pressure-sensitive adhesive is particularly excellent in adhesion to polyolefin, and can exhibit adhesion even on a rough surface. Therefore, the container body 30 is made of polyolefin, and irregularities and the like are formed on the outer wall surface of the peripheral wall portion 32. Suitable for cases. Examples of the silicone-based pressure-sensitive adhesive include those having organopolysiloxane as a main component, such as dimethylpolysiloxane having a terminal alkenyl group such as a vinyl group or a dimethylsiloxane-methylphenylsiloxane copolymer. And terminal alkenyl group-containing diorganopolysiloxane. Since the silicone-based adhesive can firmly adhere to an adherend with low wettability, a fluororesin, a polyimide resin, or the like can be selected for the container body 30. Since the polyvinyl alcohol resin and starch paste have hydrophilicity, they absorb water vapor when exposed to high-pressure water vapor, soften sufficiently and quickly, and buffer the expansion / contraction difference between the label 20 and the container body 30. For this reason, it is suitable when the label 20 is a large-sized label with a large amount of expansion and contraction.

In FIG. 1, a prefillable syringe is shown as an example of stored medical supplies. However, medical supplies are drugs such as drugs or other drugs that are listed or not listed in the Japanese Pharmacopeia used for medical care and prevention. Mechanical devices such as medical devices used for medical care and prevention, and medical devices such as medical supplies and hygiene products. Specific examples include prefilled syringes, infusion tubes, infusion bags, stents, catheters, forceps, and scalpels.

The materials of the container body 30, the nesting plate 40, and the syringe barrel 52 are selected from the viewpoints of chemical resistance, heat resistance, gas / bacteria barrier properties, safety to living bodies, and the like. For example, polyolefin resin such as polyethylene, polypropylene and cyclic polyolefin; polystyrene; polycarbonate; polyester such as polyethylene terephthalate; In particular, when sterilization is performed by an autoclave, it is preferable to use a highly heat-resistant resin such as polypropylene or polycarbonate as the material of the container body 30. Further, as the material of the syringe barrel 52, a cyclic olefin homopolymer or cyclic olefin copolymer, which is transparent so that the medicine filled inside can be visually confirmed from the outside and has little interaction with the medicine, is used. It is preferable to use it. They are formed by molding. As the molding method, an injection molding method, a blow molding method, a thermoforming method, or the like can be used, and among these, the injection molding method is preferable.

The material of the protective film 60 is a sterilized paper or resin nonwoven fabric having water vapor permeability and fine particle impermeability, or a resin sheet provided with a sterilized paper and resin nonwoven fabric. Here, the fine particles refer to bacteria, bacteria, and the like.

The medical supplies storage container to which the label on which the nonwoven sheet and the adhesive layer according to the present invention are laminated is used for transporting and storing medical supplies.
