JP2002059959A - Cup noodle container having time passing display body which discolors in steps - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate such problems that while for the cooking method for a cup needle, hot water is injected, and after l to 5 minutes, which is an optical cooking period of time indicated by the maker, the cut needle can be eaten in the set period of time, it is troublesome to measure the time by a timer, and the noodle is eaten after an approximate period of time, and therefore, the needle is too soft or too hard, and is not eaten under the best and tastiest state desired by the maker at the present time, and also, by any of conventionally suggested display methods for a time passing display body, which point is the color for the completion, processes from the initial stage to the completion of a discoloration, or a remaining period of time are hard to visually measure because the whole surface of the display body gradually discolors in the discoloration processes. SOLUTION: For this cup noodle container, on the surface of an upper lid 2 or a side surface of a cup needle container 1, the time passing display body 3 which discolors in steps is printed or pasted. In this case, the time passing display body 3 which discolors in steps is made to discolor in steps by using a temperature indicating material or a temperature sensing material, and the time passing until the completion time or the remaining period of time can be visually measured and judged.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for printing or affixing a stage-changing time-lapse indicator on the upper lid or side of a cup noodle container to measure the cooking time of instant cup noodles.

[0002]

2. Description of the Related Art (1) Cup noodles (dried noodles / raw noodles) are produced at about 3 billion meals per year, and the conventional method for cooking cup noodles is that if the cooking time indicated by the manufacturer is 1 to 5 minutes and there is boiling water, The cooking time, which can be easily eaten anywhere indoors and outdoors and can be eaten in the most delicious state desired by the manufacturer, can be measured only with a clock or timer. However, such a measurement is troublesome to measure with a clock or a timer every time, so it is roughly estimated and eaten because it is too stretched or too hard and it is not eaten in the most delicious state originally desired by the manufacturer Is the current situation. (3) For this reason, it has already been proposed to attach a time lapse display to a cup noodle container. As such a time lapse display body, the following one has been proposed, but is disclosed in Japanese Unexamined Utility Model Publication No. Heisei 2-69880, a container for snack noodles. Instant kabu noodles with indication

[0003]

The above-mentioned conventional time lapse display bodies have a display method from the initial stage (FIG. 4-MN-a) to the completion of the final discoloration (FIG. 4-M-N-b). Because the process gradually changes the color of the entire display,
(MNc) is a complete color (Fig. 4-MNd) it is difficult to determine whether it is a complete color, and it is difficult to measure the process from the initial stage of discoloration to completion and the remaining time. is there.

[0004]

According to the present invention, the display method of the above-mentioned conventional time lapse display body is stepwise changed in color by using a temperature indicating material or a temperature sensing material, and the elapsed time until the final time or the remaining time is measured and judged. A stage discoloration time lapse display that can be used.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (FIG. 1-A-B-C) is a cup noodle container in which a step-colored time-lapse indicator 3 is printed or stuck on a surface of an upper lid 2 or a side surface of the cup noodle container 1.

The indicator shown in FIG. 2 (D) senses the temperature of the hot water poured into the cup noodle container 1, and the temperature indicating material / thermosensitive material is abc.
The color changes stepwise to -d, and the progress to the final completion time d and the remaining time can be measured. In the case where the color is changed stepwise, by changing the pitch of the color change, it is possible to display a colorless time lapse display that is almost stepless.

In FIG. 2E, F, and G, a print layer 6 of characters and figures is provided on the display of FIG. 2D, characters and figures are displayed first, and disappear when the color change progresses stepwise. The display may be performed such that characters or graphics emerge from the display or vice versa.

The display shown in FIG. 2H is circular and abc-
The color is changed stepwise from the center toward the outer circle concentrically with d. Conversely, the color can be changed from the outer circle toward the center.

(FIG. 2-I) (FIG. 2-H) A print layer 6 of characters and figures is provided on the display body, and the characters and figures are displayed at first, and disappear when the color change progresses stepwise. Conversely, characters and graphics may be displayed so as to appear.

The characters and figures in FIG. DI are merely examples, and various types of characters and figures are conceivable.

The principle of the stepwise color change time lapse display is a temperature indicating material.
Material (temperature, reaction, thickness, etc.) of thermal material such as thermal decomposition method, sublimation phenomenon method, chemical reaction method, dissolution method, electron transfer method, crystal transfer method, liquid crystal phenomenon method, etc. This is a display body that displays the elapse of the stage discoloration time by changing the length or the like.

The structure 1 (FIG. 3-J) of the stepwise color change time display is a structure in which a temperature indicator (5) is sandwiched between a transparent protective layer (4) and a transparent support layer (6). 2 (FIG. 3-K) has a transparent layer (4) provided on a temperature indicator (5), and a printed layer (7) for characters and figures and a transparent support layer (6) provided below. 3 (FIG. 3-L) is provided with a heat insulating layer (8) having a changed thickness under (FIG. 3-J) (FIG. 3-K).

The present invention has a structure as described above, in which the cooking time such as 1 minute to 5 minutes is displayed by changing the color of the step discoloration time lapse display body printed or affixed to the upper lid or the side surface of the cup noodle container after pouring hot water. It is.

According to the first aspect of the present invention, the food can be eaten in the most delicious state originally set by the manufacturer without a clock or a timer.

According to the first and second aspects of the present invention, the cooking time set by the maker can be checked stepwise by estimating the elapsed time and the remaining time by the stepwise color change, and the user can eat in the most delicious state.
