Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to thermochromic plush toys. More specifically, the present invention relates to a thermochromic stuffed animal in which a light source is arranged inside the filling and a reversible thermochromic layer is provided on the surface of the skin material, which satisfies the nuances of light emission and thermochromism.

[0002]

2. Description of the Related Art Conventionally, there has been disclosed a stuffed animal which has an internal light source and emits light from the body surface, clothes, etc. when the light source is in a light-emitting state (Japanese Utility Model Publication No. 61-139282 and Japanese Utility Model Publication No. 4-11113923). No.

[0003]

The conventional plush toy has a monotonous light emitting effect, even if it is surprising, due to the light emitted from the light source provided inside. The present invention intends to provide a stuffed toy that exhibits a variety of aspects in which the effect of light emission and the effect of thermal discoloration are combined to satisfy both the lightness and darkness of the stuffed toy skin and the nuances of color change.

[0004]

According to the present invention, a filling material in which a light source is arranged is surrounded by a light-transmitting or semi-transmitting skin material having a reversible thermochromic layer on at least a part of its surface. The requirement is a thermochromic stuffed animal. Furthermore, the skin material is made of cloth or a flexible plastic material, and the surface of the skin material is formed with a reversible thermochromic layer in which the color tone at the time of coloring has a complementary color relationship with the color tone of the light source, or The non-color-changing layer and the reversible thermochromic layer are laminated, and the color tone of the reversible thermochromic layer at the time of coloring is in a complementary color relationship with the color tone of the non-color-changing layer, and the filling is a cotton-like aggregate of short fibers. It is a requirement.

The thermochromic stuffed animals are celestial bodies such as the moon, stars and the sun, people, animals and plants, fruits, vehicles, structures, food and drink,
Examples include stuffed animals that imitate various forms such as indoor equipment, play equipment, and sports equipment. As the base material that serves as the skin material of the plush toy, a knitted or woven fabric or cloth formed of natural fibers, synthetic fibers, or the like is preferably used, but a material such as plastic that transmits even a small amount of light can be used.

As the filling material to be filled in the thermochromic plush toy, those having elasticity and transmitting light such as cotton, cloth, feathers, sponge, etc. are preferably used, but especially soft hand and soft A cotton-like material of a short fiber having good transparency is preferably used so that a sufficient amount of light reaches the stuffed animal surface when the texture and the light source emit light. Alternatively, a granular resin molded product, styrofoam, or the like may be filled so that light leaks from the gap.

The light source built into the thermochromic stuffed animal is preferably a light bulb, a fluorescent lamp or the like which has been generally used in the past, but any light emitting device can be used. The power source for energizing and turning on the light source may be externally supplied from a household outlet, a battery, a dry cell or the like through a connection line, or may be a battery or a dry cell built in the inside directly. The position where the light source is arranged varies depending on the shape of the stuffed animal,
In the case of a doll, one or more dolls are installed at positions where light sources can be installed, such as the head, torso, and limbs. Further, the shape and size of the light source are arbitrarily selected depending on the size of the stuffed animal and the location of the light source. Further, the color tone of the light source may be various colors other than white, and a light source having a color tone having a complementary color relationship with the color tone of the reversible thermochromic layer in the colored state is preferably used.

The thermochromic layer is composed of a known thermochromic material, and includes, for example, an electron-donating color-developing organic compound, a developer of the compound, and a compound serving as a medium for causing a color reaction between the both. A thermochromic material containing three components or a thermochromic material exhibiting a color change in the form of fine particles of a resin solid solution of the components (for example, JP-B-51-35414, JP-B-51-44706, and JP-B-52- 7764, Japanese Patent Publication No. 1-29398, etc.). The above-mentioned color changes before and after a predetermined temperature (color change point) as a boundary, and only one specific state can exist in the normal temperature region of both states before and after the change. That is, the other state is
It is maintained while the heat or cold required to develop that state is applied, but returns to the state exhibited in the normal temperature range when the heat or cold is not applied, so-called, temperature-color density It is a type that exhibits a small hysteresis width and changes color.

In addition, Japanese Patent Publication No. 4-1 proposed by the applicant of the present invention.
The system described in Japanese Patent No. 7154, which is colored with a thermochromic material containing a color memory memorizing thermochromic dye that exhibits large hysteresis characteristics and is discolored, is also effective. The dye exhibits a large hysteresis width and changes color. That is, the shape of the curve plotting the change in the color density due to the temperature change is the case where the temperature is increased from the lower temperature side than the color change temperature range and the other is the temperature is decreased from the higher temperature side than the color change temperature range. It is a type that changes color by following a significantly different route. Further, as the thermochromic material, a microcapsule pigment encapsulated in microcapsules is preferably used in order to improve the sensitivity and sensitivity of color change.

The thermochromic material is applied as a color material such as ink or paint by dispersing a single or a plurality of thermochromic materials having different color changing temperatures in a medium containing a binder which is a film forming material. It can be applied to the surface of the skin material by a printing means such as screen printing, offset printing, gravure printing, coater, tampo printing, transfer, etc., brush coating, spray coating, flow coating, roller coating, dip coating and the like. Here, the surface of the skin material refers to the visible portion of the stuffed animal, and also means, for example, the mouth, the hole of the ear, the bag of the marsupial animal, or the inside of the stuffed animal that can be separated or opened. It is also possible to form a film sheet and attach it via an adhesive. Furthermore, JP-A-60-17
A thermochromic cloth woven of thermochromic fibers described in JP-A-9371 and JP-A-60-225369 may be used as the skin material.

A non-color-changing layer may be provided between the skin material and the reversible thermochromic layer. In this case, if the color tone of the non-color-changing layer is a color tone having a complementary color relationship with the color tone of the reversible thermochromic layer, the same decorative effect as when the light source is colored can be obtained.

The thermochromic stuffed animal obtained as described above is further colored by using a heating / cooling discoloring tool in addition to discoloring by touch in order to develop and decolor the reversible thermochromic layer. You can deepen your sex.

The heating / cooling discoloring tool will be exemplified below. The heating or cooling discoloring tools include those having a tapered tip and a writing form, or those having a stamp form in which an image of a character, a pattern, a pattern, etc. is formed at the tip, and a resistance heating element is provided. Electric heating color change tool (Shokaisho 62-13
The applicant of the present invention has previously proposed as a cooling discoloring tool 5, such as a heating pen filled with hot water or the like (disclosed in Japanese Utility Model Publication No. 2-106299). A cooling discoloring tool utilizing a Peltier element (Japanese Patent Laid-Open No. 5-318915), a cooling pen filled with a coolant such as cold water or ice pieces, and the like can be applied.

[0014]

The light emitted from the light source is transmitted through the filling material and is transmitted as uniform scattered light from the skin material to bring about a peculiar lighting effect that emphasizes the shape and color tone of the stuffed animal. Furthermore, when a cotton-like aggregate having short fibers as the filling material is used, more uniform scattered light can be obtained, and the electric decoration effect is improved. Light from the light source when the color tone and density of the reversible thermochromic layer are complementary to the color of the light source, or when the color tone and density of the reversible thermochromic layer are complementary to the color and density of the non-color-changing layer. It brings about the effect of blocking light, and by combining these, a stuffed animal with various appearances due to light and color changes is configured.
