Description

Technical Field

[0001] The present invention relates to a medical container having a port and a sheet detachably fixed to the port, and storing a medical liquid therein.

Background Art

[0002] Medical containers such as chemical solution containers and infusion containers are provided with ports for discharging the stored liquid, mixing drugs into the container, and the like. The port houses a plug made of an elastic material (rubber material, elastomer material) that can be punctured by a medical instrument (for example, a connecting needle of an infusion set, an injection needle). In addition, it is common for the port to be provided with a cap for holding the plug inside. Further, some ports have a protective sheet detachably fixed so as to cover the upper surface of the plug. This protective sheet functions to prevent contamination of the plug before use and as an indicator for confirming whether it has been used. As those having such a detachable sheet, Japanese Patent No. 5122878 (Patent Document 1) and Japanese Utility Model Publication No. 3-24186 (Patent Document 2) have been proposed. In addition, the applicant of the present application has proposed Japanese Patent Application Laid-Open No. 2018-134315 (Patent Document 3) and Japanese Patent Application Laid-Open No. 2018-138083 (Patent Document 4). Further, Japanese Patent No. 2582134 (Patent Document 5) and Japanese Patent Application Laid-Open No. 2011-78810 (Patent Document 6) have proposed those in which a laminate film of a non-detachable plastic film is closely bonded.

[0004] Recently, damage caused by foreign matter mixed into infusion solutions that occurred in multiple hospitals has been reported in the media. This is considered to be a crime in which a needle is inserted through a protective sheet and foreign matter is mixed into a medical container. In the case of an infusion solution with a protective sheet attached, medical staff consider it to be unused when the protective sheet of the infusion solution has not been peeled off. For this reason, at the time of administration, confirmation of whether the protective sheet has been punctured with a needle and confirmation of whether the stopper has been punctured with a needle after the protective sheet has been peeled off are not performed. Also, it is not easy to confirm whether the protective sheet has been punctured. It is difficult for medical staff to notice the fact of admixture at the time of administration. In this regard, the inventions of Patent Document 3 and Patent Document 4 are effective in that it is easy for medical staff to notice the fact of admixture. However, there are also infusion solutions without a protective sheet attached, and infusion solutions without a protective sheet attached require careful confirmation. Also, in the case of Patent Document 4, the laminated film of the plastic film is adhesively bonded and cannot be peeled off. However, in the case of Patent Document 4, visual recognition of the possibility of foreign matter mixing was not always easy. Also, in an infusion container, an operation of injecting another drug may be performed before administration to a patient. For this reason, the discharge port of the infusion container may be punctured multiple times. When punctured multiple times, puncturing the same site multiple times may cause liquid leakage. An object of the present invention is to provide a medical container that makes it easy to confirm when a medical instrument is punctured through a sheet fixedly adhered inseparably to the upper surface of an elastic member of a port, and surely recognizes the possibility of admixture, and can avoid puncturing the medical instrument at the same site in the case of regular admixture. [Means for Solving the Problems]

[0005] Those for achieving the above object are as follows. (1) A medical container having a container body, a medical liquid accommodated in the container body, and a port portion provided on the container body and pierceable by a medical instrument, wherein the port portion includes an elastically deformable seal member having an upper surface with a first color, and a plastically deformable sheet inseparably fixed to the upper surface of the elastically deformable seal member, the plastically deformable sheet has a second color different in hue or color tone from the first color of the elastically deformable seal member, and the plastically deformable sheet forms a puncture mark by being pierced by the medical instrument, and at the puncture mark, the first color of the upper surface of the elastically deformable seal member is directly visible, furthermore, the port portion includes a tubular opening provided in the container body, and a cap that houses the elastically deformable seal member and is fixed to the tubular opening, the plastically deformable sheet is not in contact with the cap, and at the outside of the outer edge of the plastically deformable sheet, the elastically deformable seal member is annularly exposed, and the color of the elastically deformable seal member is visible at the exposed portion. A medical container.

[0006] (2) The medical container according to the above (1), wherein the plastic deformable sheet has transparency, and the upper surface of the elastic deformable seal member is visible through the plastic deformable sheet. (3) The medical container according to the above (1) or (2), wherein the plastic deformable sheet has transparency, and the first color of the elastic deformable seal member is different from the hue or color tone of the third color in a state where the plastic deformable sheet is laminated on the upper surface of the elastic deformable seal member.

Advantages of the Invention

[0007] The medical container of the present invention has a container body, a medical liquid accommodated in the container body, and a port portion provided on the container body and pierceable by a medical instrument. The port portion includes an elastically deformable seal member having a first color on its upper surface, and a plastically deformable sheet fixedly adhered to the upper surface of the elastically deformable seal member in a non-peelable manner. The plastically deformable sheet has a second color different in hue or color tone from the first color of the elastically deformable seal member, and when the medical instrument pierces the plastically deformable sheet, a puncture mark is formed, and at the puncture mark, the first color on the upper surface of the elastically deformable seal member can be directly visually recognized.

[0008] Therefore, due to the color on the upper surface of the elastically deformable seal member being exposed at the puncture mark, and further due to the difference between the color of the exposed upper surface of the elastically deformable seal member and the color of the plastically deformable sheet portion at its peripheral edge, the puncture mark in the plastically deformable sheet can be reliably visually recognized, enabling recognition of the possibility of mis-infusion. Also, in the case of proper infusion, it is possible to avoid piercing the medical instrument at the same site.

DETAILED DESCRIPTION OF THE INVENTION

[0010] The medical container of the present invention will be described using the embodiments shown in the drawings. The medical container 1 of the present invention includes a container body 2, a medical liquid accommodated in the container body 2, and a port portion 3 provided on the container body 2 and pierceable by a medical instrument. The port portion 3 includes an elastically deformable seal member 6 having a first color on its upper surface, and a plastically deformable sheet 8 inseparably fixed to the upper surface of the elastically deformable seal member 6. The plastically deformable sheet 8 has a second color different in hue or color tone from the first color of the elastically deformable seal member 6, and when the plastically deformable sheet 8 is pierced by a medical instrument, a puncture mark 83 is formed, and at the puncture mark 83, the first color on the upper surface of the elastically deformable seal member 6 can be directly visually recognized.

[0011] The medical container 1 of this embodiment includes a container body 2 integrally having a main body portion 20 and a tubular opening portion 21, the port portion 3 is a discharge port portion 3 pierceable by a piercing member, and further, the medical container 1 includes a drug 7 filled in the container body 2. As shown in FIGS. 1 to 4, the container body 2 includes a substantially cylindrical tubular opening portion 21 having an opening at the upper end, a flat cylindrical upper portion 22 continuous with the tubular opening portion 21 and extending downward, a flat cylindrical body portion 23 continuous with the cylindrical upper portion 22 and extending downward, and a flat cylindrical lower portion 24 continuous with the cylindrical body portion 23 and extending downward.

[0012] The tubular opening portion 21 is a cylindrical portion extending a predetermined length with substantially the same inner diameter. In this embodiment, the tubular opening portion 21, in cooperation with a sealing member described later, constitutes the port portion 3. Further, the container body 2 has a closed lower surface portion 28, and a protruding portion 29 protruding downward is formed on the lower surface portion 28. The protruding portion 29 functions as a mounting and holding portion for the suspending member 4. In the suspending member 4 of this embodiment, the medical container can be suspended by bending.

[0013] And the container body 2 of this embodiment includes two upper side portions 27a and 27b provided at both ends on the major axis side of the flat cylindrical upper portion 22. The two upper side portions 27a and 27b are configured to rapidly approach toward the tubular opening 21. Further, the upper side portions 27a and 27b are curved portions that protrude outward in a substantially arc shape. Furthermore, the container body 2 includes upper central portions 22a and 22b respectively provided on the front and back surfaces of the major axis side (opposite across the major axis) of the cylindrical upper portion 22, and the thickness of the upper central portions gradually decreases from the upper end to the lower end.

[0014] Also, the container body 2 includes a flat cylindrical body portion 23 that is continuous with the lower end of the flat cylindrical upper portion 22 and extends downward. The flat cylindrical body portion 23 includes two body side portions 26a and 26b that are continuous with the lower ends of the upper side portions 27a and 27b and extend downward. The body side portions 26a and 26b are curved portions that protrude outward in a substantially arc shape.

[0015] In addition, the container body 2 includes a flat cylindrical lower portion 24 that is continuous with the lower end of the flat cylindrical body portion 23 and extends downward. The flat cylindrical lower portion 24 is continuous with two lower side portions 25a and 25b provided at both ends of the major axis of the flat cylindrical lower portion 24, and the lower side portions 25a and 25b are continuous with the lower ends of the body side portions 26a and 26b and extend to the closed lower surface portion 28. As shown in FIG. 4, the flat cylindrical lower portion 24 is formed such that its width decreases downward (toward the lower surface portion 28) and its thickness also gradually decreases.

[0016] The container body 2 is formed of a thermoplastic resin. Examples of the thermoplastic resin that is the forming material of the container body 2 include polyolefins (polyethylene, polypropylene, ethylene - propylene copolymer, a mixture of polypropylene and polyethylene or polybutene), polyesters (polyethylene terephthalate, polybutylene terephthalate), polyamides, polyvinylidene chloride, polyvinylidene fluoride, etc. Among these, polypropylene - based resins with excellent heat resistance are most preferred.

[0017] As the internal volume of the container body 2, 50 to 1600 ml is preferable, and the diameter of the protruding portion 29 is preferably about 2 to 5 mm. Further, the thickness of the main body portion 20 of the container body 2 is preferably 0.1 to 0.5 mm, the width of the main body portion 20 of the container body 2 is 60 to 150 mm, and the length of the main body portion 20 of the container body 2 is preferably 110 to 250 mm.

[0018] Next, the port portion 3 will be described. In the medical container 1 of this embodiment, the port portion 3 is a discharge port portion. The port portion 3 is composed of the tubular opening 21 of the container body 2 described above and a sealing member fixed thereto. As shown in FIGS. 4 to 6, the sealing member includes a thermoplastic resin cap (annular cap) 5 fixed to the sealing member fixing portion (annular flat portion) 75 of the tubular opening 21, and an elastic deformable seal member 6 attached to the cap (annular cap) 5 and capable of being punctured by a puncturing member.

[0019] The elastic deformable seal member 6 is one that can be punctured by a puncturing member (for example, a syringe for discharging a chemical solution), and further, the punctured portion is sealed after the puncturing member is removed. The elastic deformable seal member 6 is formed of an elastic material. As the forming material of the elastic deformable seal member 6, various rubbers such as silicone rubber, isoprene rubber, butyl rubber, and natural rubber, and various resins such as polyurethane, polyamide elastomer, polybutadiene, and soft vinyl chloride are used.

[0020] And, as shown in FIGS. 5 to 8, a plastically deformable sheet 8 that is inseparably fixed is provided on the upper surface of the elastically deformable seal member 6. The plastically deformable sheet 8 does not have elastic deformability. When a medical device (such as an infusion connecting needle or an injection needle) is punctured, as shown in FIG. 8, a through hole is formed. When the punctured medical device is removed, the through hole does not recover and becomes a puncture mark 83. And, at the puncture mark 83, since a part of the upper surface of the elastically deformable seal member 6 is exposed, the first color of the elastically deformable seal member 6 can be directly visually recognized at the puncture mark 83 portion. And, when the puncture mark is not at a normal puncture site, it can be recognized that there is a possibility of foreign matter mixing. Also, in the case of regular admixture, puncture of the medical device to the same site can be avoided.

[0021] And the plastically deformable sheet 8 is inseparably fixed to the upper surface of the elastically deformable seal member 6. For this reason, even when the punctured medical device is removed, the plastically deformable sheet 8 does not separate from the upper surface of the elastically deformable seal member 6 together with the medical device. Therefore, the puncture mark 83 surely remains on the upper surface of the elastically deformable seal member 6.

[0022] Examples of the forming material of the plastically deformable sheet 8 include polyolefins (polyethylene, polypropylene, ethylene-propylene copolymer, a mixture of polypropylene and polyethylene or polybutene), polyesters (polyethylene terephthalate, polybutylene terephthalate), polyamides, polyvinylidene chloride, polyvinylidene fluoride, polyamides, polybutadiene, vinyl chloride, etc. Preferably, those having thermo-bonding properties with the forming material of the elastically deformable seal member 6 are preferred. Also, the plastically deformable sheet 8 may be formed by laminating it on the upper surface of the elastically deformable seal member 6. As the plastic deformable sheet 8, it is preferable that the puncture mark becomes large. For example, in the case of a laminate formed by compressing a rubber stopper from the circumferential direction, tension is applied to the plastic deformable sheet 8 due to the repulsive force of the rubber, so the puncture mark is likely to spread after piercing. The thickness of the plastic deformable sheet 8 is preferably 20 to 150 μm, and particularly preferably 30 to 100 μm. The flexural elasticity of the plastic deformable sheet 8 is preferably 100 to 500 MPa.

[0023] And the elastic deformable seal member 6 has at least an upper surface having a first color. Further, the plastic deformable sheet 8 has a second color different in hue or color tone from the first color of the elastic deformable seal member 6. Furthermore, when the medical device is punctured, a puncture mark 83 is formed in the plastic deformable sheet 8, and the first color of the upper surface of the elastic deformable seal member 6 can be directly visually recognized at the puncture mark. The different hues mentioned here refer to color differences, and different color tones refer to differences in lightness or / and chroma, that is, differences in the color tones.

[0024] In the medical container 1 of this embodiment, the plastic deformable sheet 8 has transparency, and the upper surface (the form of the upper surface) of the elastic deformable seal member 6 can be visually recognized through the plastic deformable sheet 8. Furthermore, in the medical container 1 of this embodiment, the plastic deformable sheet 8 has transparency, and the first color of the elastic deformable seal member is different from the hue or color tone of the third color (mixed color) in the state where the plastic deformable sheet is laminated on the upper surface of the elastic deformable seal member. Therefore, it is easy to distinguish from the first color at the puncture mark, and the puncture mark can be surely recognized. The transparency of the plastic deformable sheet 8 is not completely transparent, and the haze value is preferably 20 to 80%, and particularly preferably 30 to 60%.

[0025] As the combination of the first color of the elastically deformable seal member 6 and the second color of the plastically deformable sheet 8 (a combination with different hues or color tones), it is preferable that the first color is an expanding color with respect to the second color. In particular, it is preferable that the first color is an expanding color and the second color is a contracting color. Note that an expanding color generally refers to a color that appears larger than the actual state, and a contracting color, conversely, refers to a color that appears smaller than the actual state. Also, as the combination of the first color of the elastically deformable seal member 6 and the second color of the plastically deformable sheet 8 (a combination with different hues or color tones), it is preferable that the first color of the elastically deformable seal member is a dark color (dark color system), and the second color of the plastically deformable sheet is a light color (light color system). In this case, the puncture mark will be such that a dark color (dark color system) such as red appears on a light background color (light color system) such as white or light gray, making it easy to grasp the change and easy to visually recognize the puncture mark. Also, as the combination of the above-described first color and the above third color (mixed color), a pattern in which one is a white system or a blue system and the other is a red system or a yellow system is also preferable. Further, the first color of the elastically deformable seal member is preferably white or gray of lightness 3 or more and chroma 1 or less, and the second color of the plastically deformable sheet is preferably any of a red system, a blue system, a green system, and a yellow system. In any case, it is preferable that neither the first color of the elastically deformable seal member 6 nor the second color of the plastically deformable sheet 8 is black.

[0026] And in the medical container 1 of this embodiment, as shown in FIGS. 4 and 5, the elastically deformable seal member 6 includes a substantially cylindrical seal member body 61, a side portion (annular side portion) 62 provided so as to cover the side surface of the seal member body 61, and a connecting portion (annular connecting portion) 64 that connects the central portions of the seal member body 61 and the side portion (annular side portion) 62. Therefore, the elastically deformable seal member 6 has a recess (annular recess) formed by the upper surface of the connecting portion (annular connecting portion) 64, the upper portion 62a of the side portion (annular side portion) 62, and the upper portion of the seal member body 61. Further, as shown in FIG. 5, the elastically deformable seal member 6 has a recess (annular recess) formed by the lower surface of the connecting portion (annular connecting portion) 64, the lower portion 62b of the side portion (annular side portion) 62, and the lower portion of the seal member body 61.

[0027] The seal member body 61 is formed in a substantially cylindrical shape and has recesses 66a, 66b, 66c serving as puncture indicators on the upper surface as shown in FIGS. 4 and 5. And in the medical container 1 of this embodiment, the plastically deformable sheet 8 has transparency, and the recesses 66a, 66b, 66c formed on the upper surface of the elastically deformable seal member can be visually recognized through the plastically deformable sheet 8. Therefore, the plastically deformable sheet 8 does not inhibit the puncture of medical instruments into the recesses 66a, 66b, 66c. Further, in the medical container 1 of this embodiment, as shown in FIG. 7, the plastically deformable sheet 8 is in close contact with the upper surface of the elastically deformable seal member 6 without any gaps. Therefore, as shown in FIGS. 6 and 7, the plastically deformable sheet 8 has recesses 82a, 82b, 82c corresponding to the recesses 66a, 66b, 66c.

[0028] Also, on the lower surface of the elastically deformable seal member 6, a skirt-shaped protruding portion 65 is provided, which is formed at the peripheral edge of the lower surface and becomes thinner toward the end. As shown in FIG. 5, this skirt-shaped protruding portion 65 penetrates into the tubular opening 21 (inside the small-diameter tip portion 74 of the cylindrical portion 73). Further, as shown in FIG. 5, the skirt-shaped protruding portion 65 becomes thinner toward the lower end and has an inner diameter that expands. Therefore, the inner surface of the skirt-shaped protruding portion 65 is an inclined surface that expands toward the lower end (specifically, a curved inclined surface that expands toward the lower end).

[0029] The port part 3 (sealing member) includes a cap (annular cap) 5 made of a thermoplastic resin fixed to a sealing member fixing part (annular flat part) 75 of the tubular opening 21. The cap (annular cap) 5 includes a cylindrical main body part 51 having an elastically deformable seal member mounting part, a protruding part (annular protruding part) 52 protruding outward from the lower end side part of the cylindrical main body part 51, and a fusion protruding part 55 protruding downward from the lower surface of the protruding part (annular protruding part) 52.

[0030] As shown in FIG. 5, the cap (annular cap) 5 has the lower surfaces of the cylindrical main body part 51 and the protruding part (annular protruding part) 52 facing the upper surface annular flat part of the sealing member fixing part 75 of the flange part 71, and the fusion protruding part 55 is melted and fixed to the upper surface annular flat part (sealing member fixing part) 75 of the flange part 71. As shown in FIGS. 5 to 8, the cap (annular cap) 5 has an opening and houses the elastically deformable seal member 6 in a state where the upper surface of the main body 61 of the elastically deformable seal member 6 is exposed at the opening.

[0031]

[0032] The protruding part (annular protruding part) 52 includes a fusion protruding part 55 extending downward from a position slightly inside its outer edge. The fusion protruding part 55 is an annular rib in this embodiment and has a reduced inner diameter and outer diameter toward the lower end. Further, in this embodiment, as shown in FIG. 5, the lower end of the fusion protruding part 55 is an annular flat surface in this embodiment. The cylindrical main body part 51 extends in a predetermined long axis direction and is substantially cylindrical.

[0033] The cap (annular cap) is formed of a thermoplastic resin. Examples of the thermoplastic resin that is the forming material of the cap (annular cap) include polyolefins (polyethylene, polypropylene, ethylene-propylene copolymer, a mixture of polypropylene and polyethylene or polybutene), polyesters (polyethylene terephthalate, polybutylene terephthalate), polyamides, polyvinylidene chloride, polyvinylidene fluoride, and the like. Further, the cap (annular cap) is preferably made of a material that is highly compatible with the forming material of the tubular opening 21 (in this embodiment, the container body 2), and particularly preferably, the same or the same type of resin is used. Furthermore, the forming material of the cap (annular cap) preferably has a lower melting point than the forming material of the forming material of the cylindrical opening 21 (in this embodiment, the container body 2).

[0034] And in this elastically deformable seal member 6, the upper part of the substantially columnar seal member body 61 has an outer diameter that is substantially the same as the diameter of the opening of the above-described cap (annular cap) 5 (the inner diameter of the inner cylindrical portion 53). And as shown in FIG. 5, the upper part of the seal member body 61 enters into the opening of the cap (annular cap) 5. Further, in the elastically deformable seal member 6 of this embodiment, as shown in FIG. 5, the upper part (annular upper part) 62a of the side part (annular side part) 62 is housed in the concave part (annular concave part) of the cap (annular cap) 5.

[0035] Furthermore, the lower part (annular lower part) 62b of the side part (annular side part) 62 of the elastically deformable seal member 6 is housed between the cylindrical main body part 51 of the cap (annular cap) 5 and the small-diameter tip part 74 of the main body part 20. As shown in FIG. 5, the lower end of the inner cylindrical portion 53 of the cap (annular cap) 5 and the upper end of the small-diameter tip part 74 of the main body part 20 face each other, and the connecting part (annular connecting part) 64 of the elastically deformable seal member 6 is clamped by the inner cylindrical portion 53 of the cap (annular cap) 5 and the small-diameter tip part 74 of the main body part 20. Thereby, the space between the tubular opening 21 and the sealing member is liquid-tight.

[0036] And in the medical container 1 of this embodiment, as described above, the port portion 3 includes a tubular opening 21 provided in the container body 2, a cap 5 that houses the elastically deformable seal member 6 and is fixed to the tubular opening 21, and the plastically deformable sheet 8 is not in contact with the cap 5. Therefore, when the elastically deformable seal member 6 is pressed by the cap 5, the plastically deformable sheet 8 does not become an obstacle, and the plastically deformable sheet 8 is not deformed by the cap 5. Also, in the medical container 1 of this embodiment, in the plastically deformable sheet 8, the elastically deformable seal member 6 is annularly exposed outside the outer edge 81 thereof, and the color (first color) of the elastically deformable seal member 6 itself is visible at this portion. By comparing the color at this portion with the color at the puncture mark 83, it is possible to easily recognize that the elastically deformable seal member 6 is exposed at the puncture mark 83.

[0037] As the medical container of the present invention, a soft bag type medical container 100 as shown in FIG. 9 may be used. And as the medical container 100 of this embodiment, as the discharge port 3, one composed of a tubular opening 21 and a sealing member is used. Also, in the medical container 100 of this embodiment, as the admixture port 104, one composed of a tubular opening 21 and a sealing member is used. The discharge port 3 and the admixture port 104 include the above-described elastically deformable seal member 6, and further include a plastically deformable sheet 8 that is inseparably fixed to the upper surface (surface) of the above-described elastically deformable seal member 6.

[0038] The sealing members of the ports 3 and 104 are substantially the same as those of the medical container 1 described above. Note that in the medical container 100 of this embodiment, a soft container 102 is used. The tubular opening 21 is formed by a separate member from the soft container, and is fixed to the soft container 102 by fixing portions 127 and 128.

[0039] In addition, the flexible container (container body) 102 of this embodiment is formed of a sheet-shaped cylindrical body. In the container body 102, a partition portion 109 is formed which partitions an internal storage portion and constitutes a releasable partition portion, and is partitioned into a first chemical solution chamber 121 and a second chemical solution chamber 122. Further, in this medical container 100, a drug discharge port 3 is attached to the first chemical solution chamber 121 of the container body 102. A first chemical solution is stored in the first chemical solution chamber 121, and a second chemical solution is stored in the second chemical solution chamber 122. The container body 102 of this embodiment includes an upper seal portion 105, a lower seal portion 106, and side seal portions 107 and 108.

[0040] The partition portion 109 includes a peelable weak seal portion 109a that crosses the entire lateral direction of the container body 102, and a substantially non-peelable strong seal portion 109b provided in the branch portions at both ends of the weak seal portion 109a. The volume of the medical container 100 varies depending on the type of drug stored inside, etc., but usually, the volume of the first chemical solution chamber is preferably about 50 to 5000 ml, and the volume of the second chemical solution chamber is preferably about 50 to 5000 ml.

[0041] As the drugs stored in each chemical solution chamber, chemical solutions, powders, etc. can be considered. In particular, in the medical container of the present invention, the first chemical solution is preferably a chemical solution. The second chemical solution may be either a chemical solution or a powder. Preferably, it is a chemical solution. Examples of the combination of the first chemical solution and the second chemical solution include combinations such as an amino acid electrolyte solution and a glucose solution, and a glucose solution and a sodium bicarbonate solution.

[0042] In the medical container 100 of this embodiment, a peelable communication inhibiting weak seal portion 110 that inhibits communication between the discharge port 3 and the inside of the container body 102 is provided. For this reason, although the discharge port 3 communicates with the empty chamber 123 inside the container body 102, it does not communicate with the first chemical solution chamber 121. The above-described weak seal portions 109a and 110 are formed by thermally sealing (heat fusion, high-frequency fusion, ultrasonic fusion, etc.) a sheet material in a strip shape.
