The embodiments of the present invention are described by way of specific embodiments, and those skilled in the art can understand the other advantages and functions of the present invention from the disclosure of the present disclosure. The present invention can also be implemented or applied by various other specific embodiments. The details of the present specification can also be modified and changed without departing from the spirit of the present invention.

As shown in FIGS. 1 and 2, the temperature sensing cup cover 1 of the present invention includes a lid body 10 and a temperature sensing member 11. The cover 10 has a first surface 101 and a second surface 102 opposite to each other and an air hole 104 communicating with the first surface 101 and the second surface 102. The temperature sensing member 11 is disposed on the first surface 101 at a distance from the air hole 104, and includes at least one thermochromic material. The temperature sensing cup cover 1 further comprises an openable outlet portion 103 and a curling edge 12, wherein the air hole 104 and the outlet portion 103 communicate with the first surface 101 and the second surface 102, respectively. In use, air can flow through the air hole 104. / in the cup 2, for the user to drink the beverage or soup in the cup 2 from the outlet portion 103; the curling edge 12 is disposed on the periphery of the cover 10, and the inner diameter of the curling edge 12 corresponds to the various cups 2 The size of the cup mouth is used to cover the temperature sensing cup cover 1 on the cup body 2; the structure of the remaining temperature sensing cup cover 1 can be designed as known commercially available cup lids, and the present invention does not impose any restrictions thereon.

Further, the thermochromic material is a material that changes or disappears with the original color as the temperature changes, and the main principle is to coat various heat sensitive substances with microcapsules (for example, liquid crystal materials or color changing materials (such as Leuco dyes)) , Among them, various thermosensitive substances may exhibit different colors in a chemical or physical change at a specific temperature (for example, eliminating discoloration or changing the alignment of liquid crystal molecules). By formulating the composition of various thermosensitive substances, the color change mode of the thermochromic material can be divided into reversible achromatic, reversible color development, reversible color, interval color development, irreversible color reduction, irreversible color development, irreversible color, etc.; The color change temperature of the color changing material may be, but not limited to, a single or a plurality of specific temperature values such as -5 ° C, 0 ° C, 5 ° C, 10 ° C, 30 ° C, 45 ° C, 60 ° C, 70 ° C; color of the thermochromic material; Contains red, orange, yellow, green, blue, black and other colors.

The temperature sensing member 11 of the present invention is disposed on the first surface 101 at a distance from the air hole 104 to prevent the heat vapor in the cup 2 from being directly transmitted to the temperature sensing member 11 via the air hole 104. The temperature sensing member 11 includes at least one thermochromic material, and the heat of the cup 2 containing the high temperature drink or the soup 3 is transmitted to the first surface 101 through the second surface 102 to a temperature above a first temperature value (for example, 45 ° C). At 60 ° C or 70 ° C), the thermochromic material causes the temperature sensing member 11 to display a first color (for example, but not limited to: red) as the temperature changes, to remind the user to pay attention to the drink or soup in the cup 2. The temperature is too high to avoid scalding accident; when the temperature of the cup 2 containing the high-temperature drink or the soup falls below the first temperature value, the thermochromic material will display the temperature sensing member 11 as the temperature changes. The second color (such as but not limited to: blue) allows the user to indirectly know if the temperature of the beverage or soup in the cup 2 is suitable for drinking.

It is worth noting that, via the simulation test results, the temperature difference between the first surface 101 and the high temperature liquid contained in the cup 2 is about 10 to 15 ° C (but not limited thereto). Therefore, in order to correctly prompt the temperature to effectively avoid accidents, The temperature member 11 indicates that the first temperature value of the first color is preferably between 45 ° C and 70 ° C, more preferably between 45 ° C and 60 ° C. In addition, the first temperature value of the first color of the temperature sensing member 11 can also be adjusted according to actual needs, and the present invention is not limited thereto. The temperature sensing cup cover of the present invention can display different colors according to the normal temperature interval and the high temperature interval, and can also adjust the composition of the thermochromic material according to actual needs, so that the temperature sensing member 11 further distinguishes the low temperature interval and displays other colors. For example, when the temperature of the first surface 101 reaches a first temperature value (for example, 45 ° C), the temperature sensing member 11 displays a first color; when the temperature of the first surface 101 reaches the first temperature value and reaches When the second temperature value is above (for example, 5 ° C), the temperature sensing member 11 displays the second color; when the temperature of the first surface 101 reaches the second temperature value, the temperature sensing member 11 displays the third color. Therefore, the temperature sensing member 11 can display different colors according to different specific temperature value ranges, so that the temperature sensing cup cover of the present invention can be adapted to sense the temperature of the hot and cold drinks.

In detail, in the temperature sensing cup cover of the present invention, the temperature sensing member may be selectively disposed on the first surface by being embedded or attached. 3 and 4 are schematic cross-sectional views showing the AA' segment in Fig. 1.

As shown in FIG. 3, in this embodiment, the thermochromic material of a specific temperature is preliminarily coated on a plastic sheet (for example, an Oriented Polypropylene film (OPP film)), and then an automated machine. The device (for example, the robot arm) adsorbs the plastic sheet to a specific position in the mold by means of a mold insert, and then ejects the plastic particles (such as polypropylene PP) through the plastic injection machine to form a temperature-sensitive cup lid. 1. The temperature sensing member 11 is embedded in the first surface 101 of the cover 10.

As shown in FIG. 4, in another embodiment, the thermochromic material is pre-coated on a plastic sheet (for example, OPP film), and a temperature-resistant adhesive is applied to the plastic sheet for subsequent use. Attaching a plurality of plastic sheets to a predetermined position on a bundle of plastic sheets (for example, a polypropylene sheet having a width of 100 cm and a length of 100 meters) by an automatic labeling device, and vacuum forming The machine forms a plurality of temperature sensing cup lids 1' on the mold by heating, vacuum forming, punching the plastic sheet, and attaching the temperature sensing member 11' to the first surface 101' of the lid body 10'. .

The above-mentioned injection molding, vacuum pressure forming or printing of the temperature sensing members 11 and 11' on the lids 10, 10' can all achieve the effect of correct temperature sensing and instant discoloration.

In summary, the temperature sensing cup cover of the present invention comprises a temperature sensing member disposed on the first surface of the cover body, and the temperature of the first surface is brought to a specific temperature value when the cup body contains a high temperature of the beverage or the soup product (such as When the temperature value is above, the temperature sensing component displays the first color in real time, and the user only needs to look at the temperature sensing component on the surface of the temperature sensing cup cover, and can indirectly know whether the temperature of the beverage or soup in the cup body is suitable for drinking. Prevent accidents from happening.

The above embodiment merely exemplifies the temperature sensing cup cover of the present invention, and is not intended to limit the creation. Any person skilled in the art can modify and change the above embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this creation shall be as set forth in the scope of the patent application attached to this case.
