Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container such as a teacup, a mug, and a cup. More specifically, the present invention relates to a container with a pattern whose appearance is changed by heat of hot water, tea, coffee or the like.

[0002]

[Prior art]

 Conventionally, a device with a thermochromic pattern of this type has been devised, as described in Japanese Utility Model Laid-Open No. 62-50999, Japanese Utility Model Laid-Open No. 1-4272, etc. The thermochromic layer is provided so as to cover the entire surface or a part of the surface.

[0003]

[Problems to be solved by the device]

 The container with a thermochromic pattern according to the above-mentioned conventional technique is not interesting because it only repeats the concealment of the underlying pattern by the addition of heat. The present invention is intended to provide a container with a thermochromic pattern that not only hides the pattern of the background due to heat but also changes the overall appearance of the pattern and strongly appeals to the user. .

[0004]

[Means for Solving the Problems]

 The present invention is provided with a pattern showing that a plurality of partial pieces are missing from the completed drawing of the puzzle, and the missing partial pieces are scattered outside the drawing, and the completed drawing of the puzzle is not discolored. It is printed with a color ink, and the part corresponding to the missing part on the completed drawing is covered with a layer of reversible thermochromic ink that changes color from colored to colorless by heat, and the scattered part at room temperature A container with a thermochromic pattern that has a shape and color tone that matches the corresponding part of the completed drawing and is printed with a reversible thermochromic ink so that it becomes colorless and transparent by heat is required.

The reversible thermochromic ink is selected from an acid-coloring type leuco dye, a phenol compound, an organic acid, etc., and an organic acid substance serving as a developer of the leuco dye, and higher alcohols, fatty acid esters, etc. The reversible thermochromic pigments of the microcapsules that are selected and contain the compatible solution of the three kinds of organic solvent compounds that determine the occurrence temperature of the color development reaction of the two are made of thermosetting resin such as epoxy resin and urethane resin. An ink dispersed in a vehicle is used (JP-B-51-44706, JP-B-51-44708, JP-B-52-7764, JP-B-1-29398, etc.). As the thermochromic pigment, a pigment whose color change point is set to a temperature of about 40 ° C. to 60 ° C. by selecting a medium organic compound is preferably used.

The reversible thermochromic ink that hides the portion corresponding to the missing portion needs to be a dark color such as black, navy blue, or brown in order to sufficiently hide the pattern of the non-color-changing ink of the base. .

The non-color-changing ink used for the completed drawing of the puzzle is prepared by dispersing a general colored pigment in the vehicle, and is printed on the container surface by a method such as direct printing or transfer printing. Further, the completed drawing of the printed puzzle can have various shapes such as a square shape, a round shape, a triangle shape, and the like, and the pieces can also have various shapes. The design of the completed drawing may be variously applied, such as a colorful painting style, a series of numbers, symbols, alphabets, and the like.

[0008]

[Action]

 In the thermochromic printed matter of the present invention, a plurality of partial pieces are missing from the completed drawing of the puzzle at room temperature, and the patterns in which the missing partial pieces are scattered on the outside of the figure are visually recognized and heated. In this state, the color of the missing parts in the drawing disappears and the background pattern is revealed, and at the same time, the scattered missing parts disappear and the completed drawing of the puzzle is visually recognized.

【Example】

 Example 1 (see FIGS. 1 and 2) A completed jigsaw puzzle composed of 12 pieces divided into 3 vertical and 4 horizontal partitions on the outer surface of a white ceramic mug 1 with a non-color-changing ink. Printed (triangular pattern printed), black on the top surface of it at room temperature, and reversible thermochromic ink that changes color to colorless at 45 ° C. The upper surface corresponding to is overprinted. Further, around the completed drawing of the jigsaw puzzle, a reversible thermochromic ink that is colored at room temperature and colorless at 45 ° C. is used to randomly arrange pieces 4 of the same shape and tone as the four missing portions 3. Printed to do.

The unfinished jigsaw puzzle appears on the surface of the mug 1 obtained as described above at room temperature, but when hot water of 45 ° C. or higher is poured, the irreversible heat of the missing portion 3 and the partial piece 4 is increased. The completed jigsaw puzzle appears when the color-changing ink disappears. When the temperature falls below 45 ° C again, it returns to its original state and can be used repeatedly.

Example 2 A complete drawing of a round puzzle composed of 16 pieces divided into 4 sections in each of the vertical and horizontal directions by a non-color-changing ink on the outer surface of a stainless steel mug (the alphabet of "CUP" is (Printed) is printed, and the upper surface corresponding to 6 missing portions of 16 pieces is overlapped with a reversible thermochromic ink that turns white at room temperature and changes color to colorless at 60 ° C. Printed. Furthermore, around the completed drawing of the jigsaw puzzle, pieces of the same shape and color tone as those of the six missing portions are randomly arranged with a reversible thermochromic ink that is colored at room temperature and colorless at 50 ° C. Printed.

In the mug obtained as described above, an unfinished puzzle appears on the surface of the cup at room temperature. However, when hot water at 50 ° C. or higher is poured, the reversible thermochromic ink of the missing part and the piece becomes unclear. The completed puzzle appears by erasing. Also, when the temperature falls below 50 ° C again, it returns to the original state and can be used repeatedly.

[0013]

[Effect of device]

 Before heating, the container with a thermochromic pattern of the present invention has a fun of imagining a completed pattern by thinking about which of the scattered pieces fits into the missing part. Also, when hot water, tea, coffee, etc. are poured and heated, the appearance of the design changes completely, and the puzzle pieces were fitted into the corresponding parts as if the puzzle pieces were completed. Unexpectedness is given.
