Description

[Detailed description of the invention] <Industrial application field> The invention is based on the invention that when boiling water is poured into the container body containing instant food and the lid is closed, a colored image that was not visible until then appears on the container body after a while. The present invention relates to a latent image coloring type instant food container that appears on the surface of the lid body to indicate when it is ready to eat, and to indicate hits and misses.

<Conventional technology and its problems> Instant foods such as cutlet ramen and yakisoba, which are ready to eat 3 to 5 minutes after pouring boiling water, often have warnings or various colored patterns printed on the container body or lid surface. There are many of them, and they have a decorative effect and look good, but since the operation is simple, just pour hot water and leave them for a certain period of time, there is a problem that there is little variety in handling and it lacks interest.

<Means for Solving the Problems> The present invention was developed in view of the conventional circumstances; that is, colored images such as letters and designs are printed at appropriate places on the surface of the main body or a lid placed on the main body; An opaque coating made of a heat-soluble substance such as wax, resin acid metal salt, or soluble polymer dispersed in resin is applied to the top surface, and a colored image appears when the opaque coating is melted by the hot water injected into the main body. In particular, it is intended to provide a latent image coloring type instant food container which solves the above-mentioned problems.

<Function> When hot water is poured into the main body and the lid is closed, the noodle bundles etc. gradually loosen and become ready to eat after a predetermined period of time. At this time, the hot water spreads throughout the container and sufficiently penetrates into the lid, and the heat melts the heat-soluble opaque film on the surface and makes it transparent, and the colored image that was latent becomes visible at the position of the opaque film. be exposed.

<Example> To describe an example in which the invention was applied to cutlet ramen, the lid body 2 placed over the top opening of the container body 1 indicates the presence or absence of a bonus along with explanatory notes, notes, and designs on the surface. A clear colored image 3 of red, blue, etc. is printed, and an opaque coating 4 made of a heat-soluble substance is applied to the upper surface of the colored image, and the colored image 3 is hidden by the opaque coating and becomes a latent image. ing. The above-mentioned thermosoluble substances include organic soluble fine particles at a temperature of 70°C or higher, such as wax, resin acid metal salts, soluble polymer powders, etc. dispersed in resin, or those formed by brushing a discontinuous film of thermoplastic resin, etc. At the same time, a harmless ingredient that becomes transparent is used, so that the lid body 2 is heated to 70 to 80 degrees Celsius by the boiling water of 80 to 100 degrees Celsius poured into the noodles in the main body.
When heated, the opaque film 4 melts and becomes transparent, and the colored image 3 on the lower surface suddenly appears, giving the appearance as if a latent image had automatically developed color. Therefore, in this case, it is preferable to color-code the colored images into "hits" and "misses" and to add a simple explanation near them.

Also, if the opaque film 3 is made to become transparent according to the time when the noodles are ready to eat, and the colored image 3, which is a latent image, is colored after pouring boiling water (for example, 3 minutes later), you can tell the time by watching the clock. The ready-to-eat state of noodles can be determined without checking.

It should be noted that the purpose of use of the colored image 3 is not limited to the above-mentioned embodiments, and it goes without saying that the format of the image such as letters, symbols, and designs does not matter. It may also be applied to the stickers used to instruct the applicant, but these also fall within the scope of the free implementation of this proposal.

<Effect of invention> The present invention exhibits the following unique effects.

(1) Colored image 3 is normally not visible, but
Pour boiling water into the container and wait for a while to form an opaque film 4.
As it becomes transparent, it automatically develops a color as if it were being exposed to heat, and the instant food can therefore be handled with unprecedented interest.

(2) If the colored image 3 has a meaning such as "hit" or "miss", it will be easier to indicate the presence or absence of extras, which was difficult to do with this type of instant food, and it will be easier to satisfy the expectations of the purchaser. can.

(3) By setting the colored image 3 to develop in accordance with the ripeness of the noodles, etc., the user can see at a glance when the noodles are ready to eat, so there is no need to worry about the time.
