[Detailed description of the invention] Container for filling substances in film bags The invention starts from box blanks Items in film bags, especially those with a volume of 31 or more, housed in a folding box formed Containers for filling quality.

This type of bag-in-box type container can be used to contain various amounts of liquid. used. i.e. for food, especially beverages, and dishwashing detergents, lubricants, etc. Such containers are known. These containers contain a bag containing the substance to be filled. Only the container needs to be manufactured from high-quality plastic material; the rest of the container, especially The part that absorbs mechanical stress can be made from inexpensive cartons such as corrugated paper. It has the advantage of being able to In this regard, the stopper should not be covered during transport of such containers. can be left inside the container, or the stopper can be provided to the consumer as a separate element. and the consumer can attach it to the container.

These types of containers have relatively large volumes, such as those used to hold wine. For example, when used as a volume of 5 to 101, the container carton has a fairly large stable It is usually made of double pleated corrugated paper to make the container. more achieved. This kind of corrugated board has high quality, for example offset printing. It is not suitable for printing and, as a result, relatively high quality is placed on such less decorative containers. Even if you store quality products, they will not be accepted by consumers. However, such a If consumers' attention is focused on containers that are desirable for their It must be easy to maintain and satisfy stability requirements.

Therefore, it is an object of the present invention to be able to print with high quality printing, and also to have sufficient Relatively large bag-in-box that maintains stability and is easy to handle Our goal is to provide molded containers.

According to the invention, this purpose is such that the box blank forms at least a two-layer bottom. In addition to the bottom flap to form a similar at least two layer top region. has a top flap to accept the injection element on the film bag An opening is punched in the top flap, and the side mold of the folding box in use is another. This is achieved by reinforcing the inner reinforcing case of two carton blanks. will be accomplished.

This aspect of the invention allows the outside of the folding box blank to be printed in a typically high quality Can be formed from relatively thin cartons or thin cardboard that can be By making the bottom and top regions have at least two layers, for example, quality can be improved. by a separate inner reinforced case which can be made from low carton or corrugated material. Adequate stability is provided as well.

Another aspect of the invention is that the first top flap section is inwardly in the assembled condition. Minutes, for injection on the folding bag or insertion of the closure element, the parenchymal from the front free end A U-shaped opening is punched out to allow passage of the closure element in the state of use. Please make sure that there is an opening punched in the upper top flap part when in use. Features.

Such a structure allows the closure element on the film bag to be opened at the factory with a U-shaped opening. and can be placed under other top flap parts during transportation and storage. and the consumer may also remove any other top flap portions that cover this top flap portion. After opening, the closure or injection element is inserted and housed inside the container, and then folded into the box the top so that it can be closed again and the injection and closure elements can penetrate. A flap portion is folded over the top of the element.

In another aspect of the invention, a small (With one other top flap part, folds back into place when assembled) the front free end of which substantially closes off the U-shaped opening. A locking flap is provided to prevent the injection element from being pulled out after insertion. It is being

That is, by using simple means, the closure and injection elements are fitted with a correspondingly shaped fixation flap. It can be kept firmly in place by a wrap.

Yet another aspect of the invention provides that, in the assembled state, the closure and injection elements The openings in the top flaps (12, 13 and 14) that accommodate the (18) characterized in that they are at least partially arranged with respect to each other so as to form a region (FIG. 5). There is.

This aspect allows the injection or faucet element to be fixed in use with relatively little stress. Over large areas, multilayer walls of precise thickness can be obtained.

In another embodiment, a chamfer is inserted into the opening of at least the lowermost flap portion. The insertion of this element is facilitated by the provision of a groove.

A further aspect of the invention provides that the insertion chamfer requires injection or closure in the state of use. It is characterized by the provision of a retaining lip which at least partially retains the element. Sunawa This top flap portion touches the underside of the injection or closure element, which means that It is particularly suitable if the fixing operation is carried out in a factory. Users can use containers that are easy to use. If necessary, tear open the corresponding part of the container and then open the other top flap. Remove the filling and closing element from the container through the corresponding opening in the wrapper and remove as required. Then it is only necessary to fix it in place with the fixing flap.

In another embodiment of the invention, the handling of the screw tap or faucet tap is capacity by providing a qualitatively U-shaped opening with side ends extending substantially at right angles to each other. becomes easier. That is, the aperture may be square or rectangular. of the corresponding shape The wall area of the injection and closure element can correspond to these three sides and This prevents the closure element from moving axially during twisting and prevents rotation of the top flap part. It resists rolling and is held firmly.

Yet another aspect of the present invention is to reduce the number of box blanks forming one side of the folding box. also has at least one double fold for providing a handle on one side; The feature is that a U-shaped opening is provided in the inner case. Due to the reinforcement provided, there is also a corresponding opening on the corresponding side of the inner case. It is distinctive in that the opening is punched out.
