2. Description of the Prior Art Such containers having a gabled closure on the head are known. For example, Tetra Pak International AB
U.S. Pat. No. 2,146,624, to U.S. Pat. No. 4,096,697, discloses such a container having one or more pressure equalizing openings located in the upper portion of the container. In patent 286,313 of Minnesota Mining Company, the cured chamfer is fixed to a gable type rib panel or roof rib panel,
A gable sealable thermoplastic coated container is disclosed that facilitates tear-free and peel-free opening. Tetra Pak International AB European Patent 185,325 discloses a package made from a support material such as cardboard coated with a thermoplastic material for liquids or the like, The packaging is
It has a cylindrical main body, which has a base and a cover with a spout that is folded in the shape of a ridge and that can be opened by opening the sealing seam, the sealing area of the spout being A sealing portion having a strong adhesive force and an abutting portion having a weak adhesive portion for peeling the sealing portion, the sealing portion having a weak adhesive force being formed by upper surfaces spaced apart from each other, and a lower level adjacent portion. Alternating,
Areas with low adhesion are 3 on the ridges and on the sides of the ridges.
It extends to the square part. The area with weak adhesion is the so-called adhesive pad.

Containers such as those described above are manufactured from prefabricated blank paper, which is a folding line that facilitates folding and container formation by folding the panels or regions forming the upper and bottom portions into defined positions. It has an appropriate configuration. The majority of the container is coated with a thermoplastic material, such as polyethylene, which makes the container liquid tight and can be folded correctly in the upright position,
Used to seal containers using heat and pressure to be sealed. The upper portion or cover of the known container is adapted to be opened by pulling the sealing seam peeled off to form a spout that satisfactorily pour out the contents of the container.

Some seams have at least some weak adhesion, while other seams in the vicinity have considerable adhesion to keep the container liquid tight during transport and before opening.

Various methods are known for making sealing seams with a weak level of adhesion. For example, areas that must have low adhesion may be coated with certain thermoplastic materials that have higher sealing temperatures than other thermoplastic materials. When performing the sealing action at the next lower temperature, areas with weaker adhesion are produced as desired in areas with the particular plastic material having a higher sealing temperature. Also, there are various shapes for the spout formed by the sealed area having weak adhesion properties. Said sealing area is formed by the pattern of raised surfaces, which are interleaved with lower level areas located on its sides. There are a number of drawbacks to using current gable containers that are difficult to open due to incorrect positioning of the adhesive pad. Another drawback of the known container is that the cardboard of the container pleats, which weakens the rigidity of the container.

[0006] Further, the consumer has at least one on the cover.
It is known that sealing seams can be easily opened at points. Unfortunately, current containers have sealing seams, which have problems opening them. Current containers must be opened in two consecutive movements. That is, (1) the wing portion of the upper panel is moved completely outward to break the upper seam. (2) Push the ends of the wings to form the spout. In particular, the second movement is not easily understood by the consumer and cannot successfully form the spout. As a result of improper operation of the second action, such as the use of tools, the fingers used are dirty, the packaging is damaged, an incorrect spout spills the contents, or the amount cannot be controlled. Happens. The present invention eliminates the second action for opening the container and requires only the first action.

[0007]

A solution to the above mentioned problem is provided by the present invention in which the lower part of the surface as described above has a central prefolded spout.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. The characteristic new structure is preferably 6
Formed by two layers, said layers comprising six adjacent regions (1,2,3,3) extending from the container as shown in Figure 2b.
4, 5, 6).

In another embodiment, the spout is a pulling device which, when fully opened, forms a larger second spout shape.
In another embodiment, the pulling device is formed from a carrier having a self-adhesive layer. The carrier can be made of paper, carton, cotton, plastic, metal, al foil and similar materials.

A carton having a gable roof has an upper panel which is sealed together to form a liquid tight seal. Opposing side panels have front and back panels folded and sealed between them. The second spout is part of the outer area of the pre-folded spout and is sealed or glued to the outer area of the pre-folded spout, i.e. the spout forms a package panel. In the closed carton position, the second spout is folded between the gable panels. When the wings are broken, the pre-broken spout is clearly visible. Until now, you had to press the end of the unbroken wing, but you can open the spout with a simple action. The consumer will soon understand how to open the container.

The spout is located at a height that allows the container to be opened with minimal tensile strength. Usually this position is
It should be as high as possible, but it depends on the height of the roof. This spout is smaller than ever. This has the advantage of simplifying the refill operation. When refilling, it is best to pour from a small orifice into a large opening. Because the pour spout is pre-folded, the tip of the opening is very sharp, making the pour more controllable when the product is used out of the pack. This is important because the product is more concentrated, the use of smaller containers is encouraged and pouring accuracy is required.

As a variant thereof, the spout can be used as a pulling device if a large opening is required. This leads to the same opening as a normal laminated carton, but the second (pulling) movement is more clearly understandable and more natural than the pushing movement. Further, the advantage that the opening is sharp remains.

The implementation of this pre-folded spout is made with cardboard of the same dimensions and requires no special material. All that is needed are additional scorelines and folds. By forming a groove in the center of the side panel adjacent to the spout, a large spout can be smoothly formed. When using a small spout, it can be reclosed better than usual. This is done by pushing the pre-folded spout back onto the gable roof. When the wings are pulled back, the spout pops out due to the memory of the material. Closing is easy. because,
This is because the area where the gable roof is open is even smaller than usual.

As a variant, the pre-folded spout helps to open the pack in a regular manner. A large spout can be easily formed by pushing the wings. Because the small spout is already in the right angle. This allows consumers to open in a legitimate way without having to change their habits. The spout is formed by pre-bending the cardboard inside the opening of the regular laminate carton to the front side. As shown in the plan view of the accompanying drawings, the key member is the upper region of the laminate where the spout is formed by 6 layers of cardboard (see Figure 2b). The drawing also shows one possible solution as to how to fold the base of the spout.

Furthermore, the base of the spout can be formed in a number of ways. The spout may be of any size and may project from the closed laminate. The spout according to the present invention can be implemented in a plastic refill pack such as a pouch. In another embodiment, two spouts can be provided in one package for maximum benefit and comfort of using the package. The container according to the invention can be used for filling all liquids of the kind which must be poured without spilling the contents of the container.

The liquid to be packed is, for example, milk, beverages, clothing softeners, household detergents, dish detergents and the like.
