Abstract

(57) [Summary] [Object] To provide a packaging container with a pattern, which can be manufactured at a low cost in a single step, and which can impart a texture or a high-class feeling to the pattern. [Structure] The packaging container 1 with a pattern is formed by expanding an upper part of a peripheral wall 3 rising from a bottom surface 5 and bending it outward, and a pattern 4 is at least an inner wall surface of the expanded peripheral wall. 2 is a convex portion or a concave portion, which is continuously or intermittently provided around, and is formed as a convex portion in order to give a three-dimensional effect. This container can be manufactured inexpensively and easily because the pattern 4 can be formed at the same time when the container is molded. The pattern 4 is provided around the upper peripheral wall so that it can be well-appeared, and it can produce a high-class feeling of stored food and can be easily mixed with other foods. Differentiation can be achieved, and the pattern 4 functions as a reinforcing rib to improve the strength of the container.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a patterned packaging container suitable for storing Chinese food, Japanese style food or any other food and selling it over the counter, and more particularly to a patterned packaging container suitable as a compressed air vacuum forming container.

[0002]

[Prior art]

 Traditionally, this type of container has been printed with a pattern that matches Chinese, Japanese, and other food products.

[0003]

[Problems to be solved by the device]

 However, conventional containers require two steps, a printing process and a container molding process, in order to provide a pattern on the container, and the pattern is also a flat pattern, so there are drawbacks such as texture and high-class feeling. It was

The present invention has been made to solve the above-mentioned drawbacks, and it is an object of the present invention to manufacture at a low cost and in a single process, and to impart a texture or a high-class feeling to a pattern. It is to provide a packaging container with a pattern that can be manufactured.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the patterned packaging container according to the present invention has a pattern in which a slight convex portion or a concave portion is formed on the inner wall surface, and the upper wall portion is expanded and bent outward. In the container, at least the upper inner wall surface is provided with a pattern of slight protrusions or depressions.

[0006]

[Action]

 By making the pattern convex or concave, the pattern can be formed at the same time when the container is molded, and the pattern becomes a three-dimensional pattern, which gives the container a texture or a high-class feeling.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The patterned packaging container 1 of the present invention may have any suitable shape as shown in FIGS. 1 and 2, but the upper portion of the peripheral wall 3 rising from the bottom surface 5 is expanded and bent outward. The pattern 4 is formed on at least the inner wall surface 2 of the expanded upper peripheral wall, which is slightly convex or concave and is continuously or intermittently provided. The above-mentioned pattern 4 can be formed in one step at the same time as the container molding by engraving a pattern corresponding to the container molding die, and it is particularly effective as a container for forming a sheet or a film under pressure and vacuum. Target.

The pattern 4 may be uneven, but it is more preferable that the pattern 4 is formed as a convex portion because it is less likely to be clogged with food residue and the like, has a high cleanliness, and has a more three-dimensional effect.

Further, since the pattern 4 is formed on at least the inner wall surface 2 of the expanded upper peripheral wall, the pattern 4 can be seen from the outside without being hidden even when the food is stored. The effect can be enhanced. Moreover, the pattern has the effect of reinforcing the container, thereby improving the strength of the container. The design of pattern 4 is not limited to the design shown in Fig. 1, but a design suitable for the type of food to be stored can be set. 4 makes it possible to produce a high-class feeling of the food and to distinguish it from other foods. Therefore, selling foods in containers will contribute to the promotion of foods. Become.

Since the patterned packaging container 1 is inexpensive, lightweight, and formed with sufficient strength for use, it is optimal to perform pressure air vacuum forming, and a polypropylene single-piece or a laminated sheet is used. It is preferably used, but other suitable synthetic resin materials may be used.

[0011]

[Effects of the Invention] As described above, in the packaging container with a pattern of the present invention, the pattern can be formed at the same time when the container is molded. Therefore, the sheet in which the pattern is printed at a fixed pitch is molded and the pattern is not displaced. There is no need for complicated molding control to mold the pattern printing sheet and the mold together, and it is possible to manufacture a container with an accurate pattern layout at low cost and simply by molding with the mold. it can.

In addition, since the pattern is formed on at least the widened inner peripheral surface of the upper part, the vertical pattern can be seen well, and the stored food can be rendered high-class and can be distinguished from other foods. Therefore, if the food container is sold as a whole, it will contribute to sales promotion and the strength of the container will be improved because the pattern functions as a reinforcing rib due to unevenness.
