Description
- The present invention pertains to a cooking state and completion indicator of instant foods such as instant noodles, which indicates a cooking state of the instant foods to allow consumers to easily identify the cooking state quickly, thereby allowing the consumers to ingest the cooked instant foods and to approximate a cooking completion time of the instant foods to prevent the consumers from wasting time while waiting for the instant foods to be cooked. The cooking state and completion indicator of the present invention is characterized in that pattern layers with various heights are installed in a cover of a disposable vessel for containing the instant foods, a temperature-sensitive material is packed in the pattern layers, and a message member is positioned under the pattern layers. When the cover of the disposable vessel is closed after hot water is placed into the disposable vessel, the pattern layers become transparent in such a way that a pattern layer with a lowest height becomes firstly transparent and a pattern layer with a highest height becomes transparent last of all, thereby letters or drawings marked on the message member positioned under the pattern layers are gradually revealed through the transparent pattern layers to allow the consumers to easily confirm the cooking state of the instant foods. When the letters or drawings on the message member are completely revealed because the pattern layers become completely transparent, the cooking of the instant foods is completed.
- Generally, instant foods, for example instant noodles popular among many consumers such as children and women are contained in a disposable vessel without a separate cooking device. In this regard, a sealing member such as a polyester film, first melts and then is attached to a top part of a main body of the disposable vessel. In order to cook the instant foods, the consumers separate a portion of the sealing member from the main body of the disposable vessel, inject hot water into the disposable vessel containing the instant foods, and wait until the instant foods cook sufficiently to consume them.
- However, the instant foods such as the instant noodles contained in a conventional disposable vessel are disadvantageous in that because the consumers cannot confirm whether the instant foods are well cooked or not unless they open a portion of the sealing membrane to check a cooking state or ingest the instant foods, the instant foods may be undesirably swollen or gelatinized for a long or short time. In detail, when the instant foods are swollen or gelatinized using hot water for a long time, a taste of the instant foods is poor. Furthermore, when the sealing member is removed prior to a set time from the disposable vessel, heat of the hot water quickly dissipates, thus the instant foods must be swollen for a prolonged time, or they are insufficiently swollen or gelatinized, thus the taste of the instant foods becomes poor. Accordingly, the instant foods must be swollen or gelatinized for an optimum time, but it is difficult to appropriately swell or gelatinize the instant foods through a predetermined method because of various factors, such as temperature changes of water.
- Efforts have been made to avoid the above disadvantages. For example, reference may be made to the utility model which has been made by the applicant of the present invention, Korean Utility Model Laid-Open Publication No. 2002-27638, which discloses a cover applied to a disposable vessel for containing instant foods. At this time, a shortening oil as a temperature-sensitive material is put on the cover and the shortening oil on the cover is coated with a transparent material. When heat emitted from hot water poured into the instant foods in the disposable vessel is transferred to the shortening oil, the opaque shortening oil becomes transparent in time. The shortening oil is completely transparent after a predetermined time at which the instant foods are appropriately swollen, thereby consumers easily confirm the completion of cooking of the instant foods.
- However, the above utility model is disadvantageous in that the consumers can confirm only the completion of cooking of the instant foods, but a cooking state of the instant foods is not indicated. Accordingly, how long do the consumers must wait until the instant foods are sufficiently cooked is unknown.
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an aspect of the present invention is to provide a cooking state and completion indicator of instant foods, which indicates a cooking state of the instant foods to allow consumers to easily identify the cooking state quickly, thereby allowing the consumers to consume the cooked instant foods and to approximate a cooking completion time of the instant foods to prevent the consumers from wasting time while waiting for the instant foods to be cooked.
- Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
- The above and/or other aspects are achieved by providing a cooking state and completion indicator of instant foods characterized in that pattern layers with various heights are installed in a cover of a disposable vessel for containing the instant foods, a temperature-sensitive material is packed in the pattern layers, and a message member is positioned under the pattern layers. When the cover of the disposable vessel is closed after hot water is poured into the disposable vessel, the pattern layers become transparent in such a way that a pattern layer with a lowest height becomes firstly transparent and a pattern layer with a highest height becomes transparent last of all, thereby letters or drawings marked on the message member positioned under the pattern layers are gradually revealed through the transparent pattern layers to allow the consumers to easily identify the cooking state of the instant foods. When the letters or drawings on the message member are completely revealed because the pattern layers become completely transparent, the consumers confirm that a cooking of the instant foods is completed.
- Therefore, the present invention is advantageous in that the cooking state and completion indicator indicates a cooking state of the instant foods to allow consumers to easily identify the cooking state quickly, thereby allowing the consumers to ingest the cooked instant foods and to approximate a cooking completion time of the instant foods to prevent the consumers from wasting time while waiting for the instant foods to be cooked.
- The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 illustrates a perspective view of a disposable vessel for containing instant noodles, to which an indicating unit of the present invention is applied; -
