The present invention is described in detail below.

Specific embodiments of the present invention will be described below with reference to the drawings.

First, we will explain the sample collection tubes and labels used in the present invention.

[Sample collection tube]
The specimen collection tube preferably has a tube body, which is a tubular container, and a stopper. Examples of specimens collected in the specimen collection tube include body fluids. Examples of the body fluids include blood, cerebrospinal fluid, and urine. The specimen collection tube is preferably a body fluid collection tube, and more preferably a blood collection tube.

Figure 6 is a front view showing a schematic example of a sample collection tube used in the present invention.

The specimen collection tube 90 shown in FIG. 6 comprises a tube body 91 and a stopper 92. The specimen collection tube 90 is a blood collection tube. The tube body 91 has an opening at one end in the longitudinal direction. The other end in the longitudinal direction of the tube body 91 is closed. The stopper 92 is attached to the opening of the tube body 91.

The pipe body 91 has a gradient angle (θ _A ) that exceeds 0°. The pipe body 91 has a portion whose outer diameter decreases from one end (opening) toward the other end.

The gradient angle (θ _A ) of the tube body used in the present invention may be 0°, may exceed 0°, may be 0.1° or more, may be 0.3° or more, may be 0.5° or more, may be 2.5° or less, may be 1.5° or less, or may be 1.2° or less.

The gradient angle (θ _A ) of the pipe body means the angle at which the outer peripheral surface of the pipe body is inclined with respect to the length direction of the pipe body. In FIG. 6, the length direction of the pipe body 91 is shown by a dotted line. The gradient angle (θ _A ) of the pipe body means the angle between a straight line in the length direction of the pipe body and a straight line parallel to the outer peripheral surface of the pipe body in a front view of the pipe body. When the length of the pipe body is L, the straight line parallel to the outer peripheral surface of the pipe body is preferably a straight line connecting a position of 0.25L from one end (opening) of the pipe body toward the other end and a position of 0.25L from the other end of the pipe body toward the one end (opening) in a front cross-sectional view of the pipe body.

The material of the tube body is not particularly limited, but examples include known materials such as thermoplastic resins such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), polymethyl methacrylate, polyacrylonitrile, polyamide, acrylonitrile-styrene copolymer, and ethylene-vinyl alcohol copolymer; thermosetting resins such as unsaturated polyester resin, epoxy resin, and epoxy-acrylate resin; modified natural resins such as cellulose acetate, cellulose propionate, ethyl cellulose, and ethyl chitin; silicates such as soda-lime glass, phosphosilicate glass, and borosilicate glass; and glass such as quartz glass, as well as combinations of these or materials that contain these as the main components.

A conventionally known plug can be used as the plug.

The specimen collection tube may also have components such as serum or plasma separation composition contained within the tube body.

[label]
The label preferably has an adhesive surface on one surface. Examples of the label include a label with product information or the like printed thereon, and a barrier film. The label may have a transparent portion. The label may be transparent except for the printed portion. In a label having a transparent portion, wrinkles and air bubbles are easily noticeable in the transparent portion. In the present invention, since the occurrence of wrinkles and entrapment of air bubbles can be suppressed when attaching the label to a specimen collection tube, even a label having a transparent portion can be suitably used.

The material of the surface of the label opposite the adhesive surface is not particularly limited as long as the material is capable of holding the label on the label holding member described below. Examples of the material of the surface of the label opposite the adhesive surface include resins. Examples of the resins include polyethylene terephthalate, polyvinyl chloride, and polypropylene.

The thickness of the label is not particularly limited. The thickness of the label may be 5 μm or more, 10 μm or more, 100 μm or less, or 50 μm or less. Labels with a thickness of 50 μm or less are particularly prone to wrinkling. In the present invention, the occurrence of wrinkling and the entrapment of air bubbles can be suppressed when attaching a label to a specimen collection tube, so that even labels with a thickness of 50 μm or less can be suitably used.

2(a) and (b) are diagrams showing an example of the peripheral configuration of the roller used in the present invention. FIG. 2(a) is a plan view showing an example of the peripheral configuration of the roller, and FIG. 2(b) is a diagram taken along line II in FIG. 2(a).

In FIG. 2, the first roller 21, the second roller 22, the first shaft portion 31, the second shaft portion 32, and the roller support base 41 of the label application device are shown. The first shaft portion 31 penetrates the first roller 21. The second shaft portion 32 penetrates the second roller 22. The first roller 21 and the second roller 22 are arranged in parallel. The length direction of the first roller 21 and the length direction of the second roller 22 are the same direction. Note that the length direction of the first and second rollers 21 and 22 is the up-down direction in FIG. 2(a) and the front-to-back direction in FIG. 2(b).

The outer shape of the first roller 21 is a truncated cone shape. The outer shape of the second roller 22 is a truncated cone shape. The first roller 21 and the second roller 22 have the same shape. The direction from the large diameter side to the small diameter side of the first roller 21 is the same as the direction from the large diameter side to the small diameter side of the second roller 22 (the direction from top to bottom in FIG. 2(a)).

The first roller 21 is a first tapered roller having a gradient angle (θ ₁ ) exceeding 0°. The second roller 22 is a second tapered roller having a gradient angle (θ ₂ ) exceeding 0°. When the gradient angle is 0°, the outer shapes of the first roller and the second roller are each cylindrical and straight rollers.

The gradient angles (θ ₁ , θ ₂ ) of the rollers refer to the angles at which the outer peripheral surface of the roller is inclined with respect to the length direction of the roller. More specifically, the gradient angle of the roller refers to the angle between a straight line in the length direction of the roller and a straight line parallel to the outer shape of the outer peripheral surface of the roller in a plan view of the roller. In Fig. 2(a) , the length direction of the first roller 21 and the length direction of the second roller 22 are each indicated by a dotted line.

The gradient angle (θ ₁ ) of the first roller 21 and the gradient angle (θ ₂ ) of the second roller 22 are appropriately changed depending on the shape of the specimen collection tube used.

The gradient angle (θ ₁ ) of the first roller 21 is preferably 0.3° or more, more preferably 0.5° or more, and preferably 1.5° or less, more preferably 1.2° or less. However, the gradient angle (θ ₁ ) of the first roller may be 0°. In other words, the first roller may be a straight roller.

The gradient angle (θ ₂ ) of the second roller 22 is preferably 0.3° or more, more preferably 0.5° or more, and preferably 1.5° or less, more preferably 1.2° or less. However, the gradient angle (θ ₂ ) of the second roller may be 0°. In other words, the second roller may be a straight roller.

In other words, it is most preferable that the gradient angle (θ ₁ ) of the first roller 21 and the gradient angle (θ ₂ ) of the second roller 22 are the same.

The absolute value of the difference between the gradient angle (θ ₁ ) of the first roller 21 and the gradient angle (θ _A ) of the tube body, and the absolute value of the difference between the gradient angle (θ ₂ ) of the second roller 22 and the gradient angle (θ _A ) of the tube body are each preferably 0.5° or less, more preferably 0.3° or less, and most preferably 0°. When the absolute value of the difference is equal to or less than the upper limit, the effect of the present invention can be more effectively exerted. Furthermore, when the absolute value of the difference is equal to or less than the upper limit, even when a specimen collection tube having a tube body with a gradient angle (θ _A ) exceeding 0° is used, the label can be attached to the specimen collection tube without tilting in the attachment process.

The manufacturing method for the labeled sample collection tube according to the present invention will be described below.

The method for manufacturing the labeled specimen collection tube includes a holding step of holding the label on an insulating portion of a label holding member having an insulating portion on its surface. The method for manufacturing the labeled specimen collection tube includes a pasting step of bringing the label held by the label holding member into contact with the outer peripheral surface of the specimen collection tube and pasting the label on the outer peripheral surface of the specimen collection tube.

Figure 3(a) is a diagram illustrating the holding step in the method for manufacturing a labeled sample collection tube according to one embodiment of the present invention.

In FIG. 3(a), a gripping member 60 is attached to the surface of the plate-like member 12 side of the label holding member 10. The gripping member 60 has a rod-shaped portion 61 and a spherical portion 62. The gripping member 60 is held to bring the first surface 11a of the insulating portion 11 of the label holding member 10 into contact with the label L. One surface of the label L is an adhesive surface. The area of the first surface 11a of the insulating portion 11 is larger than the area of the surface of the label L opposite the adhesive surface. The first surface 11a of the insulating portion 11 is brought into contact with the surface of the label L opposite the adhesive surface. As a result, the label L is held on the first surface 11a of the insulating portion 11 by the electrical interaction (static electricity) acting between the insulating portion 11 and the label L. It is preferable to bring the first surface 11a of the insulating portion 11 into contact with the surface of the label L opposite the adhesive surface so that the entire surface of the label L opposite the adhesive surface comes into contact with the first surface 11a of the insulating portion 11.

Before or after the holding step, the specimen collection tube 90 is loaded onto the first roller 21 and the second roller 22. As shown in FIG. 3(b), the specimen collection tube 90 is loaded onto the first roller 21 and the second roller 22 so that the outer circumferential surface of the tube body 91 of the specimen collection tube 90 reaches both the first roller 21 and the second roller 22.

The specimen collection tube 90 is mounted on the first roller 21 and the second roller 22 so that the small diameter side of the tube body 91 is located on the large diameter side of the first roller 21 and the second roller 22, and the large diameter side of the tube body 91 is located on the small diameter side of the first roller 21 and the second roller 22. The specimen collection tube 90 is mounted on the first roller 21 and the second roller 22 so that the other end side of the tube body 91 is located on the large diameter side of the first roller 21 and the second roller 22, and one end side of the tube body 91 is located on the small diameter side of the first roller 21 and the second roller 22. By arranging in this way, the specimen collection tube 90 can be held horizontally by the first roller 21 and the second roller 22, and the label can be attached to the specimen collection tube 90 without tilting in the attachment process.

A holder 71 and a lever 72 are attached to the stopper 92. The specimen collection tube 90 can be rotated by manipulating the holder 71 and the lever 72. The holder 71 and the lever 72 form a rotation mechanism for rotating the specimen collection tube in the label attachment device.

Figures 4(a) and (b) are diagrams for explaining the attachment step in the manufacturing method of a labeled sample collection tube according to one embodiment of the present invention. Figure 4(b) is a cross-sectional view taken along line I-I in Figure 4(a).

The label L held by the label holding member 10 is brought into contact with the outer circumferential surface of the specimen collection tube 90 mounted on the first roller 21 and the second roller 22. More specifically, the label L held by the label holding member 10 is brought into contact with the outer circumferential surface of the tube body 91 of the specimen collection tube 90 mounted on the first roller 21 and the second roller 22. In this embodiment, the gripping member 60 is held and the label holding member 10 is brought close from above the specimen collection tube 90, thereby bringing the adhesive surface of the label L held by the label holding member 10 into contact with the outer circumferential surface of the specimen collection tube 90.

For example, instead of using a gripping member, a mechanism such as a piston may be used to bring the label L held by the label holding member 10 and the specimen collection tube 90 mounted on the first roller 21 and the second roller 22 closer together, so that the label L comes into contact with the outer circumferential surface of the specimen collection tube 90. It is preferable that the label attachment device includes a moving mechanism that moves the label holding member or the specimen collection tube mounted on the first roller and the second roller so that the label held by the label holding member comes into contact with the outer circumferential surface of the specimen collection tube.

Then, the holder 71 and lever 72 are operated to rotate the specimen collection tube 90 on the first roller 21 and the second roller 22. The adhesive force between the label L and the insulating part 11 (adhesive force due to electrical interaction) is weaker than the adhesive force between the adhesive surface of the label L and the specimen collection tube 90. Therefore, by rotating the specimen collection tube 90 while contacting the adhesive surface of the label L with the outer circumferential surface of the specimen collection tube 90, the label L can be attached to the outer circumferential surface of the specimen collection tube 90, and the occurrence of wrinkles and entrapment of air bubbles when attaching the label L is effectively suppressed.

In addition, the specimen collection tube 90 may be rotated without using the holder 71 and lever 72, for example, by rotating the first roller 21 itself and the second roller 22 itself connected to a motor or the like.

The specimen collection tube 90 may also be rotated by moving the label holding member 10 while pressing the label L held by the label holding member 10 against the specimen collection tube 90.

In this way, a labeled specimen collection tube 95 can be manufactured in which a label L is attached to the outer peripheral surface of the specimen collection tube 90, as shown in FIG. 5.

In the manufacturing method of the labeled specimen collection tube, the label may be arranged around the outer periphery of the specimen collection tube in a circle that is 0.5 or more times around the circumference, a circle that is 1 or more times around the circumference, a circle that is 1.5 or more times around the circumference, or a circle that is 2 or more times around the circumference.
