Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper container that can store foods and the like, and more particularly to a paper container having a curved surface with a lid cover formed in a curved shape.

[0002]

[Prior Art]

 Conventionally, food containers that store hamburgers and the like have generally been constructed using foamed resin materials such as foamed polyethylene. At this point, the plastics container made of foamed resin has excellent heat insulation and has a curved outer shape, so the appearance is good, but pollution problems occur when it is thrown away. In addition, the use of plastic containers has recently become regulated.

Therefore, recently, a paper container 1 as shown in FIG. 4 has been used instead of the conventional plastic container. The paper container 1 is configured by connecting a body box 2 and a lid cover 3 in series, and covering the body box 2 with a lid cover-3.

[0004]

[Problems to be solved by the device]

 However, since the above-mentioned conventional paper container 1 is entirely made of cardboard, it can be easily discarded, and the pollution problem is not corrected. Since the folding curve 4 is clearly exposed on the outer surface of the side, there is a problem that the whole is angular and the appearance is bad.

The paper container according to the present invention is a completely new technology developed in view of the above-mentioned problems of the related art, and particularly, the front side end plate of the body box and the lid cover and the bottom plate or the lid plate continuous with the front side end plate. Both of them are continued as they are without providing a folding curve at the boundary of the box, and the tip of the gable plate of the body box or lid cover is gradually expanded outward, and sticking pieces are provided at both ends of the box. In addition, a technique is provided in which the edges of the side plates that are in contact with the front side gable plates are each formed in an arc shape, and the front outer shapes of the body box and the lid cover are curved. Is.

[0006]

[Means for Solving the Problems]

 The paper container having a curved surface according to the present invention is a technology that has fundamentally improved the above-mentioned conventional problems, and its gist is to center the bottom plate around both side plates, the front side end plate, the back side end plate, and the back side end plate. A body box part provided with a sticking piece for connecting these gable plates and side plates to the gable plate, and around the lid plate, both side plates, front gable plates, back gable plates, and these gable plates and side plates are connected. In a paper container in which the adhesive cover pieces provided on the gable plate are connected to both back gable plates, the bottom plate or the lid plate and the front side of the body box part and the lid cover part, respectively. They were formed by forming a curved line at the boundary with the gable plate, making them continuous with each other, gradually enlarging both sides of the front end of these gable plates, and further curving the front corner part of the side plate. Is a paper container having a curved surface.

[0007]

[Action]

 The paper container having a curved surface according to the present invention does not have a folding curve at the boundary between the body plate provided on the front side of the body box and the lid cover and the bottom plate or the lid plate continuous to the body plate and the lid cover. Since they are continuously constructed as they are, when the body box or the lid cover is assembled and constructed, the front bottom surface or the front upper surface thereof can be curved in an arc shape to form a curved surface.

Since the tip of the end plate of the body box or the lid cover is gradually expanded outward, the openings of the body box and the lid cover are formed to have a large diameter, and the side plates adjacent to the end plate are inclined. It can be done. Since the end edges of the side plates adjacent to the front side end plate are each formed in an arc shape, the corner portion of the side plate can be formed in a curved shape in a good appearance.

【Example】

 1 is a perspective view showing the overall appearance, FIG. 2 is a plan view of a blank plate of the paper container, and FIG. 3 is an assembly. It is a perspective view in the middle.

Referring to FIG. 2, the blank plate 11 of the paper container of the present invention will be described as follows. The blank plate 11 has a body box portion 12 and a lid cover portion 13 which are symmetrically formed. The body box portion 12 has side plates 15 connected to each other above and below the bottom plate 14 as a center, and a back side gable plate 16a and a front side grate plate 16b are connected to the left and right sides thereof, and the bottom plate 14 and the front gable plate 16b are connected to each other. The boundary part is formed continuously without a folding curve. The front end portions of the back-side end plate 16a and the front-side end plate 16b are gradually enlarged in the vertical direction, and sticking pieces 17 and 18 are projectingly provided at both ends thereof. A tongue piece 19 is continuously provided at the front end of the front side end plate 16b, and a cut groove 20 is provided at the central boundary between the two.

Further, the lid cover portion 13 is provided with side plates 22 which are continuously provided above and below the lid plate 21 as a center, a front side end plate 23a and a rear side end plate 23b are connected at left and right sides thereof, and the cover plate The boundary between 21 and the front end plate 23a is continuously formed without a folding curve. The front end portions of the front side end plate 23a and the back side end plate 23b are gradually enlarged in the vertical direction, and sticking pieces 24, 25 are provided at both ends thereof so as to project. The corner portion of the side plate 22 is formed in an arc shape.

Further, a tongue piece 26 is continuously provided at the tip of the front side end plate 23a, and a locking piece 27 which can be fitted into the cut groove 20 is formed at the center of the root of the tongue piece 26 by surrounding cut grooves. Has been formed. The body box portion 12 and the lid cover portion 13 are connected to each other by back side gable plates 16a and 23b, respectively. In assembling the paper container according to the present invention, as shown in FIGS. 3 and 1, first, the bottom plate 14 is centered, and the side plate 15, the back side end plate 16a, and the front side end plate 16b are respectively erected around them, and the adhesive strip is attached. The body box 12 is formed by attaching 17 and 18 to the inner surface of the side plate 15, respectively.

Subsequently, with the lid plate 21 as the center, the side plate 22, the front side gable plate 23 a, and the back side gable plate 23 b are erected around them, and the sticking pieces 24 and 25 are stuck to the inner surface of the side plate 22.

[Effect of the device]

 Since the paper container having a curved surface according to the present invention has the structure and operation as described above, the curved surface portion can be formed without causing a folding curve to appear particularly on the body box portion and the lid cover portion of the entire surface of the container. It can be formed, which allows it to be extremely clean and to reveal the image of a conventionally used plastics container. Further, it is characterized in that it is possible to form a gently sloping surface and curved corner portions on both right and left sides of the body box portion and the lid cover portion.
