Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is based on paperboard, and comprises a resin layer on the base,
The present invention relates to a composite container made of a web made of a laminated aluminum foil layer, etc., which is formed by cutting a blank from the web and folding and heat-sealing the blank.

BACKGROUND OF THE INVENTION A conventional gauge pull-top composite container 30 has a shape as shown in FIG. It is separated from the web 33 of the material in such a way that there is no waste.

At this time, the composite container 3 shown by the double arrow A in FIGS. 14 and 15
The vertical direction of 0 is the flow direction of the paperboard fibers of the web 33 (
When the blank 31 is cut in a direction perpendicular to the direction of the double arrow B), as shown in FIG. 34 are arranged side by side, and unnecessary cutting waste 35.35 is inevitably generated on the blank 31, resulting in a decrease in the production efficiency of the blank 31 from the web 33.

Further, as shown in FIG. 14, since the blank 31 is formed into a composite container 30 having a gable top 36, when the composite containers 30 after filling and molding are stacked, the gable top 3
6, which inevitably involves an air space in the shape of an upper triangular roof, which requires a wasted space compared to the amount of liquid filled. There was also a problem that loading and storage efficiency was poor when storing the products in pendas (vending machines).

In addition, in the conventional rectangular parallelepiped (ridge tile type) composite container, the first
As shown in Figure 6, the blank 3T is separated from the web 33 that is being wound 32 and is not shaped properly, but the fiber flow direction (direction of double arrow B) is shown in the container shown by double arrow A. There was a drawback that it was separated in a direction that corresponded to the vertical direction of the.

Problems to be Solved by the Invention The present invention solves the above-mentioned drawbacks of the conventional method when separating the blank 31 from the web 33 which is the winding 32.
In order to minimize the generation of cutting waste 35, the relationship between the vertical direction A of the container and the fiber flow direction B of the raw material web 33 is at right angles to each other, which is generally considered desirable. A further object of the present invention is to provide a container having a ridge-tile shape that is preferable in terms of transportation efficiency and vendor storage efficiency.

Means for Solving the Problems The present invention provides a liquid container made of a web made of paperboard as a base, on which a heat-adhesive synthetic resin layer, a barrier synthetic resin layer, an aluminum foil, etc. are laminated, The blank formed by cutting the web has a rectangular outer shape, is bent along the crease line, and is formed by heat sealing at the side and bottom seal panel portions that are continuously formed, and the upper edge periphery is formed by heat sealing. A body part which is a top seal panel part, and a flat lid body which is separate from the body part and has a heat-adhesive synthetic resin layer formed on the adhesive surface of at least the peripheral part, and All of the above-mentioned problems can be solved by forming a structure in which the peripheral edge of the lid body and the top seal panel part on the upper edge of the body part are adhesively sealed by heat sealing. .

Function: Since the liquid container of the present invention has a body portion and a lid body formed separately, when the blank forming the body portion is separated from the winding web, the fibers of the web are HaL
It is possible to cut the blank by arranging it so that it is aligned with the 2-right side, which helps improve the strength of the liquid container, and because the blank has a rectangular outer shape, it is easy to cut the blank from the raw material web. No more chips are generated during separation, and the only loss of chips is the loss from the part where the blank cannot be separated between the end of the winding web and the start of winding on the core. It is also possible to simultaneously produce the lid from the same web, which improves production efficiency from the winding of the liquid container.Furthermore, the liquid container can be made into a ridge-tile type, and the container after filling with liquid can be manufactured at the same time. This improved transportation and storage efficiency.

Depending on the application, the opening of the container can be made by drilling a straw hole in the plate-like lid member and covering the hole with an easy-peel piece, or by pasting a pull tab piece on one side of the lid member and pinching the piece. It is also possible to apply the currently commonly used opening means, such as tearing off the lid member.
