Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) In the present invention, for example, in a thermometer, a capillary for a liquid column and a scale plate having a coating layer coated with a resin member on the surface of a substrate are bonded. The present invention relates to a thermometer which is bonded by using an agent.

(Prior Art) Conventionally, a thermometer such as a thermometer (1) has a glass tube (2) having a capillary structure as shown in FIGS. 5 (a) and 5 (b), and a substrate (4) made of, for example, cardboard. Scale plate with temperature scale printed in black on (3)
And the adhesive (6) (for example, starch paste which is excellent in preventing discoloration and deterioration).

By the way, in recent years, in order to improve the design of the thermometer, a colored area (as shown in FIGS. 6 (a) and 6 (b)) is formed at the center in the longitudinal direction of the scale plate (3) on which the temperature scale (5) is printed. 7) (shown by the shaded area) is provided, and the colored area (7) is commercially available with a pink resin member, for example.

However, the colored area (7) is solid-coated with a castor oil-modified algin resin member (8), and the scale plate (3) is attached to the glass tube with an adhesive (6) such as starch paste.
When it is adhered to (2), the algit resin member (8) having a solid oil-printed property and the adhesive (6) such as starch paste are not compatible, and the adhesive (6) is repelled, so the scale plate ( 3)
It had a problem of peeling.

(Problems to be solved by the invention) Conventionally, a glass tube having a capillary structure as described above, and a colored area provided in the central portion in the longitudinal direction of the substrate are oil-coated, for example, a pink algit resin member is solid-coated. When the scale plate formed by printing the temperature scale on the colored area is bonded with starch paste, the colored area where the Algit resin member is solid-coated has water repellency,
Even if an attempt was made to adhere the hydrophilic starch paste, the starch paste was repelled, and the scale plate came off.

The present invention has been made to solve the above problems. For example, in a thermometer, when a glass tube having a capillary structure and a scale plate colored with a water-repellent algit resin member are bonded using a conventional adhesive. However, it is an object of the present invention to provide a thermometer capable of preventing the scale plate from peeling off from the glass tube and reliably bonding the thermometer.

[Constitution of device]

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a scale plate having a coating layer on the surface of which a resin member is coated, which has good adhesiveness to the substrate, A layer is a thermometer that adheres to a capillary for a liquid column using an adhesive having poor adhesion, and a coating layer that covers the surface of the substrate is characterized in that the resin member is formed of meshes or discontinuous particles. To do.

(Effect) That is, with the present invention having the above-mentioned configuration, even if the resin member coated on the surface of the substrate is adhered with an adhesive having poor adhesiveness, the mesh or defects of the resin member coated on the scale plate can be obtained. Since the adhesive enters the part of the substrate exposed from the continuous particles, the liquid column capillary tube and the scale plate can be reliably bonded.

(Embodiment) The present invention will be described below based on an embodiment shown in FIGS. 1 to 3. FIG. 1 is a plan view of a colored scale plate adhered to a glass tube of a thermometer shown in FIGS. 4 (a) and 4 (b), for example, a thermometer. The colored scale plate (11) shown in FIG. 1 is a strip-shaped substrate (4) made of cardboard, and a central portion in the longitudinal direction of this substrate (4), for example, a pink modified with castor oil as shown in FIG. A colored area (12) formed by coating a colored algit resin member (8) in a mesh (13) shape, and this colored area
(12) It is composed of a temperature scale (5) printed in black on the same material as the Algit resin. FIG. 3 is a detailed view showing an example of the mesh (13) applied to the colored area (12). The mesh (1) has a size of a = 0.1 to 0.2 mm and b = 0.05 to 0.1 mm.
3) is formed.

Thus, the thermometer (10) of the present invention is constructed such that the glass tube (2) and the colored area (12) of the scale plate (11) are bonded with the starch glue adhesive (6) as in the conventional case. It was done.

Next, the operation of the present invention based on the above configuration will be described. In FIG. 2, for example, a pink color Argit resin member modified with castor oil on the colored area (12) of the strip-shaped substrate (4).
(8) is covered with a mesh (13) (see FIG. 3).

After that, the temperature scale (5) is printed in black with an Argit resin of the same material applied to the colored area (12) as shown in FIG. 2 to form a colored scale plate (11). Therefore, by applying a hydrophilic adhesive (6) (for example, starch paste) to the adhesive portion between the scale plate (11) and the glass tube (2) as in the conventional case and adhering the adhesive, the adhesive ( 6) will enter the substrate (4) (b × b ...) Exposed in a lattice form from the mesh (13) and be attached.

Therefore, the colored scale plate (11) can be reliably bonded to the glass tube (2) via the hydrophilic adhesive (6) such as starch paste.

In the above example, in the colored area, for example, a pink algit resin member modified with castor oil was formed in a mesh-like manner, but the particles of the algit resin member may be coated in a discontinuous state. The effect of is obtained. Further, although the thermometer for the capillary tube for mercury column has been described in the above embodiment, it goes without saying that a thermometer for the capillary tube for liquid column may be used.

As described above, according to the present invention, the glass tube having the capillary structure and the scale plate formed by coating the substrate with the water-repellent resin member are bonded with the hydrophilic adhesive. In the thermometer, by making the water-repellent resin member coated on the surface of the substrate into mesh-like or discontinuous particles, since the adhesive enters the substrate not covered with the resin member, the glass tube and The scale plate has an effect that it can be reliably bonded with a hydrophilic adhesive.
