Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pudding packaging container having an inverted trapezoidal cross section.

[0002]

[Prior art]

 As a paper container for accommodating a plurality of inverted frustoconical containers such as puddings, those having an inverted trapezoidal cross section are preferred according to the outer shape of the pudding container. However, the flat mount P shown in FIG. 1 (a) is folded in four in the longitudinal direction and glued on both ends to assemble into a container (see FIG. 1 (d)), but the widths of the top side and the bottom side are different. Therefore, as shown in FIG. 1 (b), when the sheet is folded in two, both ends do not reach as shown in the figure, and automatic bonding is difficult. Therefore, it is necessary to carry out gluing by hand in a vertical folded state similar to that shown in FIG. 1 (d), which increases the production cost and cannot be stored in two folds after bonding, which is disadvantageous in that it is bulky.

[0003]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a paper packaging container having an inverted trapezoidal cross section that can be laminated by an automatic machine.

[0004]

[Means for Solving the Problems]

 In order to allow the present inventor to fold a four-fold inverted trapezoidal cross-section container having different top widths and bottom widths into an automatic machine so that the container can be folded in two, the side surface adjacent to the bottom surface is separated from the assembly folding line. It was made paying attention to the fact that it is important to form a new folding line at the lower end that can form a fold corresponding to the difference between the width of the top surface and the width of the bottom surface. A container which is assembled by folding a bottom surface 2 and a left and right side surfaces 3 and 4 of a height h from a mount P into an inverted trapezoidal cross section and connecting both ends by gluing. A fold line E is formed along the fold line C with the side face 4 to form a folded portion 41 having a width corresponding to half the width difference between the top face 1 and the bottom face 2 on the side face 4, and the fold line E is folded in two. It features a pudding packaging container with both ends stuck together in a state of For ease of description, when the folded-back portion 41 can be torn in the longitudinal direction and the container is a cylindrical container having an inverted trapezoidal shape with both ends open, the upper surface 4 is provided to prevent the container from coming off after storage. It is preferable that the corners can be folded inward and the protrusions 11, 12, 13, 14 are formed so as to prevent the corners from coming off.

[0005]

[Action]

 According to the present invention, when attaching both ends of the mount, the above-mentioned folded portion is folded back to eliminate the difference between the top width and the bottom width, and two folds are possible, so that automatic gluing is possible. is there. Also, when assembling, the container having an inverted trapezoidal cross section is assembled by folding the folding part upward.

[0006]

【Example】

 Hereinafter, the present invention will be described in detail based on specific examples shown in the accompanying drawings. In FIG. 1 (a), a left side surface 3 with a height h, a top surface side 1 with a width L1, a right side surface 4 with a height h, a bottom surface side 2 with a width L2, and an adhesive margin portion 5 are continuous, and at each boundary. Indicates a mount P on which folding lines A, B, C and D are formed, and when folded along the folding lines A, B, C and D, a cylindrical container having an inverted trapezoidal cross section can be assembled.

In the present invention, since the new folding line E is formed at the lower end of the right side face 4 along the boundary folding line C between the bottom face side 2 and the right side face 4, the folded portion 41 having the width ΔL / 2 is formed. It is tearable. This width ΔL / 2 corresponds to half of the width difference L1-L2 between the top surface side and the bottom surface side. Therefore, when folded downward at the folding line E at the upper end of the folded portion as shown in FIG. The width is increased / decreased, and as shown in FIG. 1 (c), the length L1 of the upper surface side 1 and the length h-ΔL / 2 of the side surface 4 to the upper end of the folded portion, and the length of the folded portion ΔL / 2 and the bottom side 2 The length h of L2 is equal to the length h of the other side surface, and L1 + h−ΔL / 2 = L2 + ΔL / 2 + h The adhesive margin portion 5 can be bonded in a two-fold state. Therefore, both sides are stuck together by an automatic machine, folded in two, stacked and transported.

When the above-mentioned two-fold paper container is folded at each folding line A, B, C, D at a store, a cylindrical container having an inverted trapezoidal cross section is assembled as shown in FIG. 1 (d). Be released. Therefore, in the drawing, two puddings are stored, and the four corners are pushed inward to form inward protrusions 11, 12, 13, and 14 to prevent the pudding from coming off, and the pudding is taken out by the customer. The customer can open the packaging container by tearing the folded portion 41 in the direction of the arrow in FIG. 1 (d) as needed.

[0009]

[Effect of device]

 According to the present invention, a paper trapezoidal container having a trapezoidal cross section can be folded in two, and can be pasted by an automatic machine to be folded in two and stacked, which is suitable for storing an inverted truncated cone-shaped pudding container. Packaging containers can be manufactured at low cost and can be transported without bulk.
