Description

The present invention relates to a gable-top packaging box with a gable roof, and more particularly to a gable-top packaging box for accommodating foods such as powders and solids individually wrapped or individually wrapped and then collectively wrapped.

BACKGROUND ART Conventionally, gable-top paper containers have been widely known as liquid paper containers for storing milk, juice, soft drinks, etc., and are often used as a packaging form in place of bottles and cans. Such a packaging form is so well known that when a customer sees it at a food counter in a supermarket or the like, it is determined that the contents contained therein are food-grade liquids (for example, see Patent Document 1).

Utility model registration No. 2589886

The gable-top paper container typified by Patent Document 1 is opened through a rib panel, and the rib panel is provided with a temporary attachment part to make it easier to open. However, the parts other than the temporarily attached parts are strongly bonded to prevent the liquid contents from leaking. Therefore, when the container is opened, the paper of the paper container causes delamination, and the rib panels tend to be folded and wrinkled, resulting in poor appearance. Furthermore, when it is desired to show the goods to the customer, a packaging box equipped with a window is used. Although a packaging box with a window allows the product to be viewed and appeals to customers, the packaging box is rectangular, making it difficult to differentiate the product from other products when displayed in a store. It is.

Further, since conventional packaging boxes are mainly rectangular parallelepipeds, there is a problem in that all products look the same and it is difficult to differentiate them from other products. On the other hand, users of packaging boxes are demanding the development of new packaging formats that are highly displayable when displayed in stores.

The present invention has been made to solve the above problems, and its purpose is to provide a gable-top packaging box with a new packaging form that is highly displayable in stores.

In order to achieve the above-mentioned object, the present invention according to claim 1 includes: a cylindrical trunk section in which four side panels are connected; a bottom section connected to the lower end of the side panel; a gable roof connected to the upper end of the body, the gable roof having roof gable panels facing each other in one direction, and facing each other in two directions intersecting the first direction, and A gable-top packaging box comprising a roof panel into which the roof gable panel is folded in while facing each other, and a ridge portion projecting upward at a portion where the upper portions of the roof panel touch or are close to each other, The ridge is connected to the upper end of one of the roof panels facing each other in the two directions, and the insertion piece is extended to the upper end of the other roof panel, and The gable top packaging box is characterized in that the insertion piece is bent in the two directions and inserted between the panel and the folded roof gable panel.

Further, the present invention according to claim 2 provides the gable top type packaging box according to claim 1, in which the ridge portion is formed of a first ridge portion forming piece in order via a fold line at the upper end of the one roof panel. The second ridge forming piece and the folding piece are connected, the inner surfaces of the first ridge forming piece and the second ridge forming piece are overlapped, and the folding piece is bent toward the one roof panel side. It is characterized by this.

The present invention can provide a gable-top packaging box with a new packaging form that is highly displayable at stores. In addition, the insert piece that extends to the other roof panel can be inserted freely between one roof panel and the folded roof gable panel, so that after opening the package, you can take out the contents as needed and reseal them. be.
