Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing soap with a cross-sectional pattern, in which the same pattern appears on the cut surface no matter which part is cut.

(Prior Art) Traditionally, soaps have had a manufacturer's name, mark, or other pattern printed on their surface in order to provide an advertising effect.

However, most of these are stamps on the surface of the soap, and the current situation is that the stamps disappear as the soap is consumed. In order to overcome this reduction in advertising effectiveness, several methods have been proposed to date to produce soap with cross-sectional patterns that remain even after the soap is consumed.

For example, methods for manufacturing soap with a marble pattern have been well known, but these methods simply mix two different colors of soap in an extruder and a die attached to the tip of the extruder to create a marble pattern. Since this method extrudes soap that has a certain pattern on its cross section, it cannot be applied to soap that has a certain pattern on its cross section.

In addition, as another method, Japanese Patent Publication No. 64-44007 discloses a method for manufacturing soap in which a pattern is applied to the core by forming a large number of pore groups and then infiltrating dye into an arbitrary pattern. ing. However, in this manufacturing method, a pattern is formed by forming a large number of pore groups as described above, so in order to form a complex pattern, it is necessary to arrange a very large number of pore groups. In addition, due to the design, voids are created between the pore groups, so it is very difficult to express even the minute points of the pattern.

In addition, Japanese Patent Application Laid-Open No. 51-67700 discloses that in the extrusion molding process, a device consisting of a die with a double tube structure inside which a die for forming a pattern is placed is used to produce soap having a pattern on its cross section. A manufacturing method is disclosed. That is, as shown in Fig. 6, two extrusion molding machines (1) and (4) each having a soap component supply port (1a) are installed together, and the discharge of the die (2) of one extrusion molding machine (1) is Exit part (3)
Extend the discharge port (6) of the die (5) of the other extrusion molding machine (4), and open the discharge port (6) @ (7a
) terminates slightly inside the circumferential end (7b) of the discharge port C), and its opening (7a) is formed in a 7-shape as shown in FIG. Further, the discharge port portion (6) is formed by gradually reducing its outer diameter, and at the same time, the discharge port portion (3) is formed by gradually reducing its outer diameter.
The inner diameter of the discharge port 6) is also formed by decreasing from the contraction start position of the discharge port 6) with a taper between the passages. (1b) is a motor. Then, one extrusion molding machine (1) extrudes the soap member into the discharge port (5) of the die (2), and at the same time, the other extrusion molding machine (4) extrudes soap of a different color from the soap member. A bar-shaped soap is continuously manufactured by extruding and molding a member into the discharge port side of a die (5). However, in this manufacturing method, as shown in FIGS. 8(a) to (c), the 7-shaped soap is discharged from the discharge port (6) of the die (6) of the other extrusion molding machine (4). , the elliptical soap dispensed from the outlet (3) of the die (2) of one extrusion molding machine (1) did not fit properly inside the soap, and was deformed as shown in Figure 8 (c). It will fit in the same state. this is,
Of the two extrusion molding machines (1) and (4) installed above, one extrusion molding machine (1) and the other extrusion molding machine n (4)
) This is thought to be due to the fact that the amount of extrusion of the soap member varies over time. In other words, the soap components supplied to the one and other extrusion molding machines (1) and (4) are prepared by saponifying fats and oils with alkali as a pre-process (7), and cooling and solidifying the resulting product into flakes or powder. After drying, fragrances, pigments, and other additives are added, and the mixture is thoroughly mixed and stirred in a mixer so that it is evenly distributed.The manufacturing process is to turn it into pellets. The degree of mixing is not uniform among all soap components and varies, resulting in variations in physical properties such as viscosity, hardness, and melting point of the soap components. The physical properties of the above soap member are as follows: extrusion molding machine (1), (4) and die (2).

It greatly affects the fluidity of the soap material in (F+) and affects the extrusion rate, and it is extremely difficult to properly control the extrusion rate of such Nl soap components at all times. Therefore, the resulting soap with a cross-sectional pattern is
As a result, it was virtually impossible to produce soap with a cross-sectional pattern that contained a clear 7-character pattern.

As described above, with the conventionally known techniques, it has not been possible to produce soap having a complex and fine pattern on its cross section.

In addition, because the soap with a cross-sectional pattern manufactured by the above manufacturing method has insufficient adhesion between the pattern periphery and its outer periphery, the pattern periphery tends to peel off with repeated use, causing product equipment to deteriorate. The drawback was that it was severely damaged.

(Problems to be Solved by the Invention) This invention was made in view of the above circumstances, and its purpose is to make patterns such as letters and figures always appear in a proper state on the cut surface, To provide a method for producing soap with a cross-sectional pattern, which has a high advertising effect, does not peel off even after repeated use, and has a clear pattern.

(Means for Solving the Problems) The above object is to create a state in which the shaping cylinder, in which the opening is formed in the desired shape, has its axis approximately parallel to the axis of the discharge opening of the die. Using a die device installed in the above-mentioned cylindrical body, a soap member for pattern formation is supplied into the cylindrical body through a cylindrical channel having an enlarged portion in the middle, and The soap material is fed into the outlet on the outer periphery through a cylindrical flow path with an enlarged part in the middle, and the bar-shaped soap that always shows the same pattern on the cut surface perpendicular to the longitudinal direction is continuously fed from the outlet of the die. This is achieved by a method of manufacturing soap with cross-sectional patterns, which is extruded into a mold.

That is, through a cylindrical flow path having an enlarged portion in the middle,
By supplying each soap member to the die, the soap member for pattern formation and a different soap member are always automatically controlled and supplied in an appropriate ratio. Therefore, it becomes possible to continuously manufacture bar-shaped soap that shows an appropriate pattern on the cut surface no matter which part is cut.

Furthermore, by providing a heating or cooling means for the cylindrical flow path having an enlarged portion in the middle in the above-mentioned shaping cylinder, the peripheral line portion of the pattern portion can be melted or solidified, and contact with the outer peripheral portion thereof. The surfaces can be firmly bonded.

(Examples) Next, the present invention will be described in detail based on examples.

FIG. 1 and FIG. 2 are explanatory diagrams of a manufacturing apparatus used in the present invention. In these figures, (8) is a die, and (10) is a cylinder for type 2, the opening of which is formed in the shape of a spade. This shaping cylinder (10) is inserted into the discharge port (9) of the die (8) with its axis inserted into the die (8).
It is placed parallel to the axis of (11) is a wall formed deep inside the discharge port (9) of the die (8), and (12) is a wall formed on the surface of the wall (11) in the circumferential direction as shown in FIG. It is an opening formed along ζ,
In this case, four are formed. (11a) is a wall formed deep inside the shaping cylinder (10);

It is connected to the. Cl8) is a first extrusion molding machine, and its discharge nozzle (19 mm) is fitted into the flow path (2B) extending from the large-diameter cylindrical first enlarged part (17). , an opening at the innermost part of the shaping cylinder (1o) (
13), a cylindrical flow path (2o) extends rearward,
A large diameter cylindrical enlarged part (21) is formed in the middle part,
Further, a small-diameter cylindrical flow path (22) extends from the cylindrical enlarged portion (21) and is bent at a right angle in the middle. (2B) is the second extrusion molding machine, and its nozzle (2B) is the second extrusion molding machine.
4) and the cylindrical flow path (22) are in communication with each other. That is, the first and second extrusion molding machines (18)
, (2i$) are arranged with their axes perpendicular to each other.

Each of the extrusion molding machines (1g) and (2J) is individually provided with a driving motor (not shown). Reference numeral (25) is a base on which the above-mentioned flow path is formed, and is made of a groove made of iron or the like.

Using such an apparatus, soap with cross-sectional grooves is manufactured in the following manner. That is, the first extrusion molding machine (1
A white soap material is discharged from the nozzle (19) of 8) into the cylindrical channel (26). This discharged soap member passes through the first enlarged portion (17) and further passes through the small diameter cylindrical channel (
16), through the second enlarged portion (15), further through the narrow channel (14), and is discharged from the circular opening (12) in the discharge port (8) of the die (8). In addition, from the nozzle (24) of the second extrusion molding machine (23), soap members of other colors pass through the cylindrical flow path (22), via the intermediate enlarged part (21), and then into the small diameter cylindrical flow path. (20) and is discharged into a spade-shaped shaping cylinder (10) into the body.

In this case, the first and second extrusion molding machines (18),
The soap material discharged from the nozzles (19) and (24) of (25) is directly transferred to the discharge port (11) of the die (8).
The enlarged part (i5), (1
7), (21), the expanded portions (15), (17),
In (21), -d is accumulated.

Therefore, the first and second extrusion molding machines (18)
, (25) the physical properties of the soap components supplied from the previous process (
(viscosity, hardness, magnetic point, etc.) are different, and the nozzle (4s) of the first and second extruder (1g), (23).

Even if variations occur in the amount of soap components supplied from (24), the variations will be reflected in the enlarged portion (15).

(17) and (21), from the opening (12) formed deep inside the discharge port (9) of the die (8).
At the same time, a constant amount of soap components is always discharged, and at the same time, a constant amount of soap components of other colors are also discharged from the opening (13) deep inside the shaping cylinder (10). become. Therefore, it has a rod-like rectangular shape. That is, no matter which part of the bar-shaped soap is cut, a spade-shaped pattern will appear properly on the cut surface.

In addition, in the above-mentioned example, a different color soap member is used as the pattern forming material extruded from the second extrusion molding machine (23), but the pattern forming material is not limited to this. For example, a soap member containing microcapsules or gold foil may be used, or a soap member in the form of a sol or gel may be used.

Also, soap components having different formulations and physical properties may be used. In that case, the outer periphery of the patterned portion may peel off due to external pressure during use, so as shown in FIG. A heating means such as a W heat heater or a hot water jacket (
, 50a) or cooling means such as a cold water jacket (30
b) is desirable.

That is, the peripheral edge of the pattern forming material is heated by heating means (30a).

Alternatively, by using the cooling means (30b) and setting the temperature slightly higher or lower than the supply temperature of the forming material, the forming material discharged from the discharge port (9) can be firmly melted or solidified and bonded to the external member. This makes it possible to prevent the outer peripheral member from peeling off even when external pressure is applied.

Alternatively, the heating means (30a) and the cooling means (30b) may be used together; for example, the cooling means (301)) is provided around the discharge port (9), and the flow path (22), C20) and the enlarged part ( 21) is provided with a heating means (30a), the pattern forming material is cooled only at the discharge port portion while maintaining a suitable flow temperature. For this reason, the pattern forming material is suitable for shape retention at the discharge port portion and hardens, making it possible to further stabilize the pattern.

Further, the cooling or heating means (30) is provided not only in the cylindrical flow path in the shaping cylinder (10) but also in a flow path (26) provided in the outer periphery discharge port of the shaping cylinder. .

(16), (14) and the enlarged portion (151 (17)) may be provided in part or all.

That is, by providing the cooling means or heating means in at least one of the flow path of the pattern forming material or the flow path of the outer peripheral member, the temperature difference between the pattern forming material and the outer peripheral member can be adjusted, and the temperature difference between the pattern forming material and the outer peripheral member can be adjusted. The outer peripheral member can be firmly bonded.

Furthermore, although the spade-shaped pattern is formed in the above embodiment, several types of shaping cylinders (1a) are arranged in the discharge port (8) of the die (8), and extrusion molding is carried out there. By supplying several types of soap parts of different colors from the machine, it is also possible to manufacture soap with a cross-sectional pattern that has a multicolored and complex pattern inside.

Furthermore, in the above embodiments, one and the other extrusion molding machines are provided with their nozzle axes orthogonal to each other, but they may be provided in parallel.

Furthermore, as shown in FIG. 4, the present invention provides a flow path (14),
You may make it use the manufacturing apparatus which provided flow regulating valves (27) and (28) in (20). That is, by providing the flow rate adjustment valves (27) and (28), the extrusion amount of each channel can be further finely adjusted, which is suitable for manufacturing soap with even more accurate and complicated patterns. Furthermore, the flow rate regulating valves (27) and (2g) may be located at any position within the cylindrical channel regardless of the actual position, and the number thereof is not limited. In addition, as shown in FIG. 5, a hot water jacket (29
) may be used. That is, by attaching the hot water jacket (29), the temperature inside the base (25) and the die (8) can be maintained at a desired constant temperature, which also makes it possible to create more accurate and complex patterns. It is suitable for producing soap having Furthermore, flow regulating valves (27) and (215) are provided,
At the same time, a manufacturing apparatus equipped with a hot water jacket (29) may be used.

(Effects of the Invention) The method for manufacturing soap with a cross-sectional pattern of the present invention uses a cylindrical channel having an enlarged portion in the middle, and by combining these channels, a pattern is formed on the cut surface. Even if the physical properties of the supplied soap parts vary and the amount of soap parts etc. discharged from the nozzle of the extrusion molding machine changes, the change will be absorbed by the enlarged part in the middle of the cylindrical channel. . Therefore, the horizontal pattern is always formed in a stable state. As a result, it becomes possible to continuously manufacture bar-shaped soaps that always properly display the same pattern in a cross section perpendicular to the longitudinal direction. That is, the manufacturing method of the present invention can produce soap with a cross-sectional pattern that has excellent advertising effects or is rich in interest and cuteness.

In addition, by providing a cooling or heating means in the flow path inside the cylinder, even if the physical properties of the soap material in the pattern part and its outer periphery are different, the pattern part and its outer periphery can be firmly melted or solidified. Since the outer part can be bonded with soap, the outer part will not peel off even if soap is used repeatedly.

Further, since the heat retaining means locally heats only the peripheral edge of the patterned portion, there is no deterioration of physical properties or deterioration of the appearance of the soap member, and it is possible to manufacture soap with stable quality.
