Cup assembly having a temperature notification function according to an embodiment of the present invention is a flat bottom portion 10, the inner wall 20 is formed to be connected to the bottom portion 10 to contain the contents, and the inner wall ( 20 and the outer wall 30 formed at regular intervals, the thermochromic portion 40 interposed between the inner wall 20 and the outer wall 30 and discolored by a temperature change, and the bottom portion 10 and Located on the upper side of the inner wall 20 and the outer wall 30 to face the upper cover 50 for disconnecting the contents from the outside, one side of the upper cover 50, the upper cover 50 It includes a discharge port 60 through which the contents can be discharged to the outside and the discharge port blocking unit 70 for opening and closing the discharge port 60.

The bottom part 10 is formed in a flat shape so that the cup assembly according to the present embodiment can be supported on the floor, and a part of the bottom part 10 is formed to be inwardly concave so that it does not fall even on an uneven ground. Can be. The shape of the entire cup assembly may be determined according to the shape of the bottom portion 10. That is, when the bottom portion 10 is circular as shown in FIG. 1, the side wall connected to the bottom portion 10 surrounds the outer circumference of the bottom portion 10 in the form of a cylinder or truncated cone, and the bottom portion 10 is In the case of a quadrangle, the side wall connected to the bottom portion 10 may be formed in a square pillar shape. 1 illustrates a case in which the bottom portion 10 is circular, but is not limited thereto.

The inner wall 20 and the outer wall 30 form a double wall structure of the cup assembly of this embodiment. As described above, the side wall is formed to be connected to the bottom portion 10 to contain the contents, and the inner wall 20 and the outer wall 30 are spaced apart from each other by a predetermined interval. The material of the inner wall 20 and the outer wall 30 is not limited, and different materials may be used. That is, since the inner wall 20 directly touches the contents, the inner wall 20 may be formed of a heat insulating material to block the heat transmitted when the hot beverage or the like touches the inner wall 20 so that the user does not get burned when holding the cup assembly. On the other hand, the outer wall 30 may be formed of a material thinner than the inner wall 20 because the outer wall 30 is spaced apart from the inner wall 20 by a predetermined interval so that the heat transferred from the contents to the outer wall 30 is not large.

In particular, the cup assembly having a temperature notification function according to the present embodiment may further include a display unit 80 that is externally interposed in an empty space between the inner wall 20 and the outer wall 30, in which case the outside In addition, the outer wall 30 may be formed of a transparent material so that the contents of the display unit 80 can be recognized. The display unit 80 may include information such as a pattern or a designed character to make the appearance of the cup assembly more beautiful. Alternatively, if the cup assembly is ordered separately, a desired phrase or picture may be included.

Apart from the display unit 80, the thermochromic unit 40 may be interposed between the inner wall 20 and the outer wall 30 or discolored by a temperature change formed in a portion of the display unit 80. That is, a portion of the display portion 80 inserted to improve the appearance of the cup assembly may be formed as the thermochromic portion 40. In addition, the thermochromic portion 40 may be formed in the entire space between the inner wall 20 and the outer wall 30, and may be formed only in a part of the space. Since the thermochromic portion 40 is changed in color by receiving the temperature of the contents contained inside the inner wall 20, the thermochromic portion 40 is preferably an inner wall between the inner wall 20 and the outer wall 30. It can be in close contact with (20) to facilitate the color change.

The thermochromic portion 40 includes a thermochromic ink in which a color different from the existing color is received by receiving heat, and a specific color is expressed according to an external temperature or a specific color disappears. Therefore, at room temperature, the cup assembly according to the present embodiment is kept colorless, for example, and when hot beverage is contained in the cup assembly, the cup assembly is colored, for example, red due to heat transferred from the hot beverage to the thermochromic portion 40. Can be expressed. A specific configuration of the thermochromic portion 40 will be described later in detail with reference to FIGS. 5 to 9.

The thermochromic portion 40 may be interposed between the inner wall 20 and the outer wall 30 in the form of sprayed, printed or coated with a thermochromic dye on a paper material, in addition to the thermochromic on the thin film substrate as described below The dye may be in sprayed, printed or coated form. However, the present invention is not limited thereto and may be implemented in various other forms.

An upper cover 50 formed on the inner wall 20 and the outer wall 30 constituting the side wall of the cup assembly facing the bottom is formed to disconnect the space inside the inner wall 20 from the outside. Therefore, the contents contained in the inner wall 20 are not allowed to leak to the outside even when the cup assembly is moved while holding the cup assembly, and foreign matters such as external dust are not introduced into the contents. The material of the upper cover 50 is not limited, but there is no limitation as long as the material can withstand the heat because high temperature vapor is generated by the upper cover 50 while the contents of the high temperature evaporate. The upper cover 50 is coupled to be in close contact with the inner wall 20 and the outer wall 30, it may be provided detachably from the cup assembly. For example, the upper cover 50 may be opened by rotating the upper cover 50 counterclockwise.

One side of the upper cover 50 is formed with a discharge port 60 through which the contents can be discharged to the outside through the upper cover 50. Since the discharge port 60 is provided, the user holding the cup assembly may drink the beverage contained therein through the discharge hole 60 without opening the upper cover 50.

When the discharge port 60 is always open, foreign matter may enter the contents contained therein, and a high temperature content may be quickly cooled, so that the discharge port 60 may be selectively shut off. The unit 70 may further include. Discharge port blocking unit 70 may be in the form of a plug so that one end thereof is connected to the upper cover 50 and seal the discharge port 60, but is not limited thereto.

As such, the cup assembly having the temperature notification function according to the present embodiment includes a thermochromic part 40 which is discolored by a temperature change between the inner wall and the outer wall, so that when the cup assembly contains high temperature contents, Discolored by the heat transferred from the contents, the user of the cup assembly can intuitively know that the contents are high enough to cool down before drinking them.When the contents are cooled down to the proper temperature, they are discolored to the original color and drinkable to the user. Indicate that it is a suitable temperature.

In the present embodiment, it is assumed that the cup assembly contains a high temperature content. However, the present invention is not limited thereto, and even when the low temperature content is contained, the temperature of the thermochromic portion 40 decreases due to the low temperature inside. It may also be configured to. That is, it may be provided with a thermochromic portion 40 using a thermochromic dye that is discolored when a predetermined temperature or less.

That is, when a beverage close to 0 ° C. is filled in the cup assembly, it may be configured to recognize that the cold beverage is filled in the cup assembly from the outside.

As will be described later, the thermochromic portion 40 is coated on a substrate using a thermochromic dye that is discolored in various colors at different temperatures, or is provided in a form of coloring a thermochromic dye directly on a portion of the display portion 80. As a result, the entire side of the cup assembly may be discolored, and a part of the photo, pattern, etc. of the display unit 80 may be discolored. For example, when a predetermined pattern is displayed along with a caution statement to be careful of high temperature on the display unit 80, the caution statement is displayed using a thermochromic dye that is colorless at 50 ° C. or lower and turns red at 50 ° C. or higher. If the cup assembly is filled with a beverage at 80 ° C, the caution statement will turn red. Therefore, it is possible to draw attention of the user, especially infants or children, so as not to drink hot drinks immediately.

Next, with reference to FIGS. 5 to 9, the thermochromic portion constituting the cup assembly having a temperature notification function according to an embodiment of the present invention will be described. 5 is a cross-sectional view showing a laminated structure of the thermochromic portion constituting the cup assembly having a temperature notification function according to an embodiment of the present invention, Figure 6 is a cup assembly having a temperature notification function according to an embodiment of the present invention FIG. 7 is a cross-sectional view illustrating another stacking structure of the thermochromic unit constituting the thermochromic part, and FIG. 7 is a view illustrating a principle of color change according to the configuration of FIG. 6, and FIG. FIG. 9 is a cross-sectional view illustrating another laminated structure of the thermochromic portion constituting the assembly, and FIG. 9 is a view illustrating a principle of color change according to the configuration of FIG. 8.

The thermochromic portion 40 of the cup assembly having a temperature notification function according to the present embodiment is formed on the substrate 41 and at least one surface of the substrate and has a first color but is discolored at a first temperature. (42), and may further include a second thermochromic layer 43 having a second color and discolored at a second temperature. That is, when the thermochromic layer 40 is composed of one or more thermochromic layers, various colors are expressed according to respective expression temperatures, thereby providing more accurate temperature information to the user.

The base 41 is a configuration forming the center of the thermochromic portion 40 and functions to protect and support the thermochromic layers 42 and 43. The base 41 may be in the form of an optical sheet made of synthetic resin, in addition, may be a transparent plastic-based, or may be an opaque material. Substrate 41 is a tough and light material in the form of a film is preferably made of PVC or PET excellent in the protective action. However, the present invention is not limited thereto and may be made of various other materials.

The first thermochromic layer 42 serves to change the color of the thermochromic portion 40 of the cup assembly having the temperature notification function according to the present embodiment according to the actual temperature. The first thermochromic layer 42 may refer to a form in which a thermochromic dye is coated on a transparent ultra-thin sheet or a layer itself on which a thermochromic dye is formed, which is also configured in the second thermochromic layer 43 to be described later. Can have Thermochromic ink refers to a special dye in which a specific color is expressed or disappears depending on the external temperature. Depending on the manufacturing method, various colors may be expressed or disappeared by various reaction temperatures. Thermochromic dye particles have a size in micro units, and the form can be made in the form of capsules or slurries. In addition, when the temperature rises or falls, the color is changed into a reversible pigment that is changed and then returned, and once the temperature is changed, the color is permanently changed into an irreversible dye that does not return to its original state.

Thermochromic dyes maintain a constant chemical bonding structure above the induction temperature, but below the induction temperature, the chemical bonding structure is deformed to reflect light of a specific wavelength and exhibit a color. If the temperature is maintained above the induction temperature, the chemical bond structure is deformed to reflect the light of a specific wavelength, thereby producing a color. That is, it is divided into a high temperature thermochromic dye and a low temperature thermochromic dye, and thus a cup assembly having a temperature notification function according to the present invention may also be manufactured as a high temperature sensing film and a low temperature sensing film. In addition, each structure has a type that is colorless in the temperature range outside the induction temperature but colored in the temperature range within the induction range. On the contrary, it may be manufactured in a type that changes colorless in the temperature range within the induction temperature range. It may be produced in a type that changes from colored to other colors. Various types as described above may be combined to display a desired color above or below a specific temperature according to a required condition.

The thermochromic layers 42 and 43 coated with the thermochromic ink may be formed on one surface of the substrate 41, but as described above, the thermochromic portion 40 is directly formed on a portion of the display portion 80. In this case, the thermochromic layers 42 and 43 may be directly formed on the surface of the display unit 80 without a separate substrate 41.

The first thermochromic layer 42 of the present embodiment includes the thermochromic dye, and the color changes when the temperature becomes higher than a certain high temperature, or the color changes when the temperature becomes lower than a predetermined low temperature so that the user can detect it. Hot beverages, for example coffee, are provided to the cup assembly at a temperature of 80 ° C. to 90 ° C. If the coffee at that temperature is consumed immediately, there is a risk of burns. Therefore, the first thermochromic layer 42 employing a thermochromic dye that discolors when heat is transferred from the hot coffee to the first thermochromic layer 42 according to the present embodiment for a predetermined time, for example, 1 minute. In this case, the user may sense that the user has reached the appropriate drinking temperature by discoloring such as discoloration, for example, changing from red to transparent color when the drinking temperature is reached.

The second thermochromic layer 43 to which the thermochromic dye of the same principle as the first thermochromic layer 42 is applied may be further added, and the first thermochromic layer 42 and the second thermochromic layer 43 are The response temperature or the expression color may be different from each other. That is, the color of the first thermochromic layer 42 is expressed at 60 ° C. or lower, and the color of the second thermochromic layer 43 is expressed at 80 ° C. or higher, so that the user can detect the temperature rise step by step. That is, when the hot beverage is provided to the cup assembly and exposed at a temperature of 80 ° C. or more for a predetermined time, the chemical structure of the second thermochromic layer 43 is modified so that the second thermochromic layer 43 For example, a color of red may be expressed, and as time passes, when heat is transferred for a predetermined time at 60 ° C. or more and 80 ° C. or less, the color of the first thermochromic layer 42 is changed. When the temperature is lowered to 60 ° C. or lower, the chemical structure of the first thermochromic layer 42 is deformed so that the color of the first thermochromic layer 42 becomes colorless, so that a warning message for high temperature disappears. can do. Therefore, the user can visually confirm that the warning phrase has disappeared and can grasp that the contents have reached the appropriate drinking temperature.

Since the first and second thermochromic layers 42 and 43 are included, the colors of the first or second thermochromic layers are not individually expressed, and the colors of the first and second thermochromic layers 42 and 43 are It may be expressed by mixing.

That is, FIG. 7 is a diagram illustrating a structure in which a mixed color is expressed. For example, a color (B) expressed by the first thermochromic layer and a color (C) expressed by the second thermochromic layer are mixed. Color A may be expressed. For example, when the first thermochromic layer 42 expresses the color B at 50 ° C., and the second thermochromic layer 43 exhibits the color C at 60 ° C., the temperature gradually increases at room temperature. As it rises, the color may change from B to A.

On the other hand, in the case where a thermochromic ink that dissipates the color above the sensitive temperature is used, the color of the first and the second thermochromic layers 42 and 43 is expressed at 50 ° C. or lower, so that A color is shown, and then 50 ° C. In the above, since the first thermochromic layer reacts and the color disappears, only the C color is expressed. In such a case, thermochromic ink particles having a primary color such as intense red may be preferably used for C so that a warning notification can be surely delivered to the user.

FIG. 8 is a cross-sectional view illustrating another laminated structure of the thermochromic portion constituting the cup assembly having a temperature notification function according to an embodiment of the present invention. The substrate 41 has a first color and is discolored at a first temperature. And a second thermochromic layer 43 having a second color and discoloring at a second temperature, and a colored layer 44 having a constant color and not changing with temperature. .

The colored layer 44 is a layer having a constant color and, unlike the first and second thermochromic layers 42 and 43, does not discolor in response to temperature. Therefore, the color of the colored layer 44 is continuously expressed regardless of the temperature. The principle of color change of a cup assembly having a temperature notification function according to an embodiment of the present invention including a colored layer 44 is shown in FIG. 9.

For example, when a thermochromic dye used in a cup assembly having a temperature notification function according to an embodiment of the present invention is above a temperature of response, a chemical bond is separated and transparently discolored, and the first thermochromic layer 42 The first temperature at which color change (colorlessness) is 50 ° C, and the second temperature at which color change (colorlessness) of the second thermochromic layer 43 is 60 ° C, and all the color layers 42, 43, and 44 are different. Let's assume that. At this time, when the colors of the color layers 42, 43, 44 are H, I, J, respectively, at 50 ° C. or lower, the color D is a mixed color of three colors, and the heat is changed by the contents contained in the cup assembly. When transferred to the unit 40 and rises above 50 ° C., the color H of the first thermochromic layer 42 disappears to indicate G color. When the heat transferred to the thermochromic portion 40 increases, the color I of the second thermochromic layer 43 disappears when the temperature is 60 ° C. or more, so that only J color, which is the color of the colored layer 44, is finally removed. Expressed.

Specifically, the first to third color change layer may be provided, and the first to third color change layers may be formed of three primary colors of red, blue, and yellow, respectively, to express various colors by mixing them. According to this principle, various color combinations can be implemented, and a plurality of thermochromic layers may be used in addition to the first and second thermochromic layers, and as described above, in addition to the type in which the color is dissipated and transparently discolored above the temperature of response. A type may be adopted in which the color is expressed above the response temperature, and a type may be used in which the color is expressed or disappeared below the response temperature. Therefore, the user can detect the color changing in a predetermined form in accordance with the rise in temperature, so that the contents inside the inside of the drinking temperature range by the cup assembly having a temperature notification function according to the present invention without a separate temperature sensor It is easy to check with the naked eye, and it is possible to prevent safety accidents such as burns in advance.

In the above embodiment, the structure having the first and second thermochromic layers 42 and 43 has been described, but it is obvious that the third or more thermochromic layers can be added. Detailed temperature information for each temperature section can be delivered to the user through color.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is to be understood that the present invention is not limited to the above-described embodiments, and various modifications may be made within the scope of the present invention. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
