Description

Easy-to-open carton pack

The present invention relates to a carton pack for storing liquids such as milk, and to a carton pack having a hole (U hole) that can be easily drilled on the inclined surface of the top panel so that the contents can be easily poured.

To explain in more detail, a "U"-shaped half-cut line with a hole (U hole) on the slope of the top panel, with an open top on the outside, and a "U"-shaped half-cutting line with a closed top on the inside The half-cut line provided on the inside is positioned so as to be completely included in the half-cut line provided on the outside, and the lower end of the half-cut line is located adjacent to or adjacent to the upper horizontal folding line, so that opening is easy. It is easy and relates to an easy-to-open carton pack that can stably maintain the opened state.

Carton Pack is a kind of liquid beverage packaging container that can contain milk or juice. It is made from a fabric made by coating sterile polyethylene on both sides of a cardboard made of natural pulp as a raw material. Manufactured in a shaped container.

There are two types of carton packs, the Gable Top Type, which has a triangular roof shape, and the Brick Type, which has a brick shape. More than 95% of containers use gable top type carton packs.

1 shows an exploded view of a gable top type carton pack according to the prior art, and FIG. 2 shows a perspective view of a gable top type carton pack according to the prior art. By folding, it can be made into a box-shaped three-dimensional structure.

The material is made of a triple structure, and it is composed of a paper 22 and a polyethylene resin coating layer 23 that is thinly coated on the upper and lower portions, and the upper portion of the carton is bonded to form a triangular roof shape.

In particular, the upper ends face each other so that their faces coincide, and the polyethylene resin coating layer 23 inside the paper 22 is fused to each other when passing through the heating roller in that state, so that the upper part of the carton is sealed.

However, if the upper end of the carton is joined only by the bonding force between the polyethylene resin coating layer 23 in this way, the bonding state of the carton after packaging can be maintained well, but the spout (front) 24 and the spout (side) ) (25) and (25') between the bonding state is too strong, there is a problem that it is difficult to open the spout when the user wants to drink the contents.

Accordingly, in the carton according to the prior art, as shown in FIGS. 1 and 2, the spout part (front) 24 at the time of bonding the carton by forming the silicone coating part 27 on the inner surface of the spout part (front) at the top of the carton. ) and the spout (side) 25 and 25 ' are bonded with the silicone coating part 27 interposed therebetween, and the bonding force of the silicone coating part 27 is weaker than that of the polyethylene resin coating part 23, so the packaging Later, when the user wants to open the spout to drink the contents, there is an advantage that it can be opened more easily.

However, in the carton of the above structure, since there is a problem that the bonding force of the silicone coating unit 27 is too weak, it became a cause of poor oil leakage of the product in transportation or product display stand.

Meanwhile, in the prior art, in order to solve this problem, there was a structure in which a plastic cap was mounted (spout cap) by drilling a hole in the inclined surface of the top part and opened by turning the cap lid. There was also a structure equipped with a small hole in the slope of the top part so that the contents could be drunk using a (straw).

When the spout cap is mounted on the top part, the convenience of opening and storage is increased, but there are problems of cost increase and environmental pollution due to the use of plastic caps, and there is a problem of having to separate and dispose of the carton packs when recycling them.
