Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a microwave oven cup intended to prevent spilling when food is cooked (boiled and stewed) with a microwave oven or the like.
[0002]
[Prior art]
Conventionally, paper cups have been widely used for cold drinks and hot drinks. Plastic cups are also widely used for frozen desserts and foods. In recent years, any cup has been used for the purpose of heating and cooking in a microwave oven with contents such as instant foods inside.
[0003]
[Problems to be solved by the invention]
However, the conventional cup has a problem in that when the contents are put up to the inset line indicating the upper end where the contents are put and cooked with a microwave oven or the like, the heated contents are blown out of the cup. .
[0004]
In order to solve this problem, there is a method of using a relatively deep cup and making the cup capacity sufficiently large compared to the amount of the contents. The state in which the contents are contained is not preferable in terms of bulkiness and product sensation, and also increases in cost. There is a demand for a cup for a microwave oven that prevents these contents from being blown out during heating.
[0005]
An object of this invention is to provide the cup for microwave ovens which prevented the blowing of the content by heating, when cooking with a microwave oven etc.
[0006]
[Means for Solving the Problems]
The present invention for solving the above problems, cooked in a microwave oven, comprising a body portion and a bottom portion, an inverted frusto-conical plastic cup which upper that is vacuum formed is open, the body portion at least when cooking features on the instruction line, to form a longitudinal groove of the plurality of at predetermined intervals on the inner surface, that the outer surface of the barrel and a smooth surface showing the upper end of the contents of the case to put the contents A microwave cup.
[0007]
According to the present invention, by providing a vertical groove on the inner surface of the body of the cup, when the contents are cooked in a microwave oven, a microwave cup that can prevent the contents from being blown out by heating is obtained. be able to.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below in detail with reference to the drawings.
[0019]
Figure 1 is a perspective view showing an actual施例microwave cup of the present invention. The microwave oven cup B is a plastic cup, and the body 1 and the bottom 2 are integrally formed.
[0020]
In addition, an indication line P indicating the upper end of the contents when the contents are put is provided in the upper part of the body part 1 in the shape of a convex part on the inner surface side around the entire circumference. The indication line P may be a concave shape on the inner surface side.
[0021]
Furthermore, in the microwave oven cup B of the present invention, as shown in the Y-Y cross-sectional view of FIG. 2 , a vertical groove Q is provided on the inner surface of the body 1 of the plastic cup.
[0022]
The vertical groove Q is provided on the inner surface of the body 1 of the plastic cup from near the bottom 2 to near the upper end of the body 1. In particular, the upper end of the vertical groove Q is provided above at least an indication line indicating the upper end of the contents when the contents of the body portion are put in at the time of cooking . More desirably, the upper end of the vertical groove Q is preferably close to the upper end of the body 1. Moreover, you may set the lower end of the vertical groove | channel Q in the position of the range of 10-20 mm from the bottom part 2. FIG.
[0023]
The number of longitudinal grooves Q are provided a plurality of, more preferably be provided four or more. The intervals of the vertical grooves Q are provided at regular intervals .

[0024]
The shape of the vertical groove Q is semicircular in cross section, but it can be a quadrilateral shape, a trapezoidal shape, a triangular shape, or the like, and is not particularly limited. The width of the vertical groove Q is preferably 1 mm or more and the depth is preferably 0.5 mm or more.
[0025]
Further, the processing method for providing a Tatejomizo Q on the inner surface of the plastic cup, electrostatic the microwave oven cup B, and it is a plastic cup, molding and also perform processing of the longitudinal groove Q at the same time the cup molding Can do. That is, in the molding process, the vertical groove Q can be processed simultaneously with the molding of the cup by using a mold in which a vertical groove can be provided in advance.
[0026]
Next, materials used for the microwave oven cup B of the present invention will be described. When the microwave oven cup B is manufactured from a plastic sheet by vacuum molding, examples of the plastic sheet material include polypropylene resin, polyethylene resin, polyethylene terephthalate resin, polystyrene resin, and polyvinyl chloride resin. Further, an inorganic filler can be mixed into these resins, or a foamable resin can be used.
[0027]
When the microwave oven cup B is manufactured by injection molding, plastic materials include polypropylene resin, polyethylene resin, polyethylene terephthalate resin, polystyrene resin, polycarbonate resin, acrylonitrile copolymer, polyvinyl chloride resin and the like. can give. Alternatively, an inorganic filler can be mixed into these resins.
[0028]
【Example】
Hereinafter, the microwave oven cup of the present invention will be specifically described with reference to practical examples.
[0032]
<Example> A plastic having a height of 110 mm, an inner diameter of an opening of 10 mm, an outer diameter of a bottom of 65 mm, and a wall thickness of 1 mm, using polypropylene resin as a material. A cup was molded. Simultaneously with this molding, eight vertical grooves Q having a width of 2 mm, a depth of 0.5 mm, and a semicircular cross section were provided at equal intervals. The position where the vertical groove Q was provided was from the bottom 20 mm from the bottom 2 and the top 5 mm from the upper end of the body 1. In this manner, a microwave oven cup B was produced.
[0033]
The instant instant noodle noodles, ingredients, seasonings, and water are poured to the indicator line P and cooked in the microwave oven in the microwave oven paper cup B of this embodiment, and the contents are heated without spilling. I was able to cook.
[0034]
【Effect of the invention】
However, in the microwave oven cup of the present invention, by providing a vertical groove on the inner surface of the cup body, when the contents are cooked in the microwave oven, it is possible to prevent spilling. That is, the heated contents rise from the bottom of the cup along the inner wall of the barrel and blow up upward. By having the vertical groove on the inner surface, the boiled bubbles escape along the vertical groove and can be prevented from rising, and can be prevented from being blown. Therefore, there is an effect that it is possible to prevent spilling when cooking with a microwave oven or the like even when the cup is relatively shallow, without enlarging the size of the cup.
