  The present invention has been made in order to solve the above-mentioned problems, and its purpose is to improve the appearance by adopting a convex portion having a function of preventing damage to the packaging container surface, a function of preventing deflection, and a function of improving design. Another object of the present invention is to provide a packaging container which is not easily damaged and is not easily bent.

  In order to achieve the above object, the present invention provides a plastic packaging container for storing an article therein, the packaging container having a projecting pattern on its surface, and the projecting pattern The height of is in the range of more than 1 mm to 30 mm or less.

  In the present invention, the convex portion of the picture pattern may be provided at a corner portion on the same surface of the packaging container.

  Moreover, in the said invention, you may employ | adopt what consists of the shape of the picture pattern which followed the surface edge part of the said packaging container as the convex part of the said pattern. The convex part of the continuous picture pattern along the packaging container surface edge causes an effect of making the packaging container difficult to bend (a function of preventing the deflection of the packaging container surface by the convex part). In particular, when the thickness of the packaging container is within a range of 0.2 mm to 0.5 mm and the height of the convex part is more than 1 mm to 30 mm or less, the function of preventing the deflection of the packaging container surface by the convex part is effectively exhibited. The Accordingly, the ratio of the thickness of the packaging container to the height of the convex portion (= {height of the convex portion 2} / {thickness of the packaging container 1}) is a minimum of 2 (= 1 mm over / 0.5 mm) and a maximum of In the range of 150 (30 mm / 0.2 mm), this function is effectively exhibited.

  In the present invention and the embodiment thereof, the “height of the convex portion” H is the surface of the packaging container 1 on which the convex portion 2 is provided as shown in FIGS. 2 (d) (e) and 4 (d). To the apex (the highest place) of the convex portion 2. In addition, in the definition of the height H of this convex part, in the example of FIG.2 (d) and the example of FIG.4 (d), the front 1A or back surface 1B of the packaging container 1 is made into the measurement standard of the height of the convex part 2, In the example of FIG. 2 (e), the side surface 1 </ b> C of the packaging container 1 is used as a measurement standard for the height of the convex portion 2.

  According to the present invention, as a specific configuration of the convex portion on the surface of the packaging container, a configuration is adopted in which the height of the convex portion is greater than 1 mm to 30 mm. For this reason, for example, when this type of packaging container is stacked, the direct contact between the packaging container surfaces is avoided by the convex portions having the height interposed between the packaging containers. It is possible to achieve an effect (a function of preventing damage to the surface of the packaging container due to the convex portion) that the scratches on the surface of the packaging container due to rubbing of the surfaces are greatly reduced. In addition, such a convex portion reinforces the surface of the packaging container around the convex portion, so that the effect of preventing the packaging container from being bent (a function of preventing the deflection of the packaging container surface by the convex portion) is also obtained.

  Furthermore, in the present invention, since the convex portion of the picture pattern is adopted as the specific configuration of the convex portion on the surface of the packaging container, the convex portion itself has a design value, and the design property of the convex portion is improved. The function can provide a good-looking packaging container.
