Description

The invention relates to a packaging material-saving, reclosable, bag-like Container or sealed-edge pouch, which is also used for the targeted distribution of its contents can be, as well as a process for its manufacture, filling, sealing and Reseal after an application.

In particular for packaging food, but also other consumer goods, is known, packaging in the form of bags or sealed edge bags made of composite material, To use film, paper or the like.

Here, for example, a first cut is used as a base to which this is directed packaging product is applied in doses. After that, a second cut is made the first, lower cut, including the product on it placed on top and permanently connected to each other along the sealing edges, e.g. B. means Ultrasound, welding or previously appropriately applied adhesive. There If the product is positioned exactly on the bottom blank, it will be in shape e.g. B. a cone attached to it. The cone resulting from the dosing quantity base area and the spreading radius of the Product requires a relatively large area of the blank to be joined Arrange marginal zones with certainty outside the dosing product to be able to, for. B. the product particles located in the glue or the sealing zone Capping process would be sensitive and negatively affected. The same applies Dimensions also for other closing methods.

So are relatively packaging materials used packaging for mostly low content to explain quantities that entail a considerable amount of waste. Also mean the large-area containers caused by the filling process described also include one large energy consumption when the edge zones (sealing edges) are welded, such as this is known from the most used sealed edge bags. With appropriately large As a result, the bag area increases the edge distance to be sealed (seal edge length).

It is also possible to remove the remains of a donation from the edge of the seal often not possible because it is stuck there. Also a safe reclosure of one such a sealed edge bag, after a partial consumption of its content, is without aids hardly possible.  

The present invention has for its object a container, one on it adapted filling and closing process and its reclosing process propose with which the disadvantages described from the prior art be eliminated.

This task is done by a bag-like container according to the proposed Claims 1 and 2 solved.

A method for filling and closing the container is in the claim 11 reproduced.

A procedure for reclosing the container after partial removal its content is given in claim 12.

Appropriate refinements and advantageous developments are in the Subclaims marked.

It becomes a bag-like container, consisting of a square, in particular rectangular or polygonal cut proposed, the cut by at least partially merging and joining two of its edges, which consist of one go out common point, formed into a closed, bag-like container is, and wherein the blank is in one piece and by merging these two adjacent edge sides formed a first common contact zone and to one Apex is permanently connected, and two other adjacent to each other Edge sides delimit a free section and with their common border point are fed to the apex of the first contact zone, the edge sides in each case with their parallel side halves, two further contact zones that follow the filling of the container are also permanently closed.

Up to 60% of packaging material is Savings achieved, and when using the sealing edge closure with ultrasound or welding can save up to 50% energy. The size of the necessary packaging material is optimized by optimizing the volume reduced. The protection of the content is also improved since it is far apart horizontal arrangement of the walls of the container according to the invention. At the same time with an improved handling an optionally lockable again lockability enabled.  

The container according to the invention provides better protection of the contents against Won crumbs.

The container according to the invention is suitable both for holding powdery, granular or poured goods as well as pasty, liquid or gelled donated goods.

The products packaged in this way can be made from the same container according to the invention can be removed once or in portions and thus an inexpensive Disposable spreader form what in particular z. B. in the care of passengers or the like can improve current handling. A loss of quality is through the, if desired, lockable reclosability without tools, in comparison to the state of the art, almost impossible.

With the invention, it is not only possible to use the conventional sealed edge bags (sealed edge bags), but also folding boxes, because with the invention The container also has sufficient soil stability and thus stability and stackability is gained. Due to the reclosability with locking, the advantage is also achieved that larger quantities of product are filled into the container can, especially since the shape of the container is greater stability than that Most folding box offers by the consumer even after opening the container nisses can be stored for a longer period of time without an unwanted Distribution or loss of quality would be feared.

In an expedient embodiment of the invention it is provided that the contact zones (connection zones), which later form sealing edges, are glued.

The application of the adhesive is free of the product, as this is in the first step before the Product filling is attached and used and in the second step after such Product filling that the contact zones (adhesive zones) no contact with the filling product to have.

In other expedient embodiments of the invention, the contact zones (Connection zones) are welded by means of ultrasound, heating, etc.; esp special sealing edges can be formed here.  

Through a funnel-shaped design of the container and without the spreading radius can cut to the same content, much smaller than in the prior art be chosen and still a precise distribution of the content and a multiple Can be reclosed with a lock on the container. Also a quick removal of all of its contents is guaranteed by opening the bottom.

An advantageous embodiment of the invention provides that a sole of a container is directed upwards and is used as a resealable dosing and spreading tip. For this purpose, a marking, tear line or built-in can be made on the outside of the blank Vulnerability should be provided along which the sole cut or torn off becomes. Also a sole perforated in the toe area, the holes in its unbe used state by means of z. B. a removable cover are covered, each container converted into a common but very inexpensive disposable spreader, and is like the previously proposed task solutions content of this invention.

A special feature of this invention is that between the edge sides halved free section forms a base of the container. As a result of that the bottom is an integral part of the container blank, can be a relatively rational Folding technology can be used to form containers.

On the one hand, according to the invention, it is expediently provided that:

• - The three contact zones of the molded container have a common exit own point;
• - the common starting point of the contact zone vertices of the first Contact zone is and that
• - The through the mutually parallel edge side halves of the blank Contact zones formed by the apex of the contact zone on one and by means of one of the means enclosing a folded or folded edge points of the margins are limited.

This creates a funnel-shaped container according to the invention, the one reduced length at connection points d. H. to be glued or welded Has contact zones.  

This ensures, among other things, that the container according to the invention consists of one shaped or folded blank of a versatile jacket.

For the purpose of facilitated closing and shaping technology is fiction according to that provided by the edge-side zones of the inner surface of the blank a connecting edge is formed. These are at least partially to a support edge (Contact zones) angled and / or bent.

By closing the contact zones formed from edge side halves, the Bottom of the container with those permanently attached, being in the area in which the meet both bottom seal edges with the apex, straight or crooked runs outside. These inventive configurations of the bottom when closing the container serves the best possible with minimal use of material and energy To achieve connection between the contact zones.

To keep the floor straight after closing the container one contact zone must overlap the other in its contact area (itself with cross her) before the two contact zones of the floor are permanently connected.

According to the invention, the two contact zones forming the apex also run in their area facing the opening, straight and by means of an obliquely inward directed weld seam are permanently connected, the floor must be in its contact with the Vertex adjacent area curvature to the outside to create a tight connection guarantee between the contact zones. The straightening also according to the invention the bottom is reached by at least one kink at the apex, this from the common point from which the two bottom seal edges and the apex originate and meet, must go out.

The container is preferably resealable on its sole in which it is re-closed its previous opening, at least once purposefully rolled up or together is folded and by a sideways fold of the first formed Siegelrandes (crown), can be locked, but this is not a condition.  

It is also provided that at least the inside of the blank from one to the Suitable food intake material is made, the cut as before mentioned, consist of composite material, film, cardboard or paper-like material can. If no food is packed in the containers according to the invention, can the food safety of the packaging material is waived.

In an expedient embodiment of the invention it is provided that the blank at least on its inside with a product that contains diffusion and Absorption protective coating is provided.

Another advantage of this invention is that both the contact zones between the edge side halves separable to form a dispensing opening as well as the sole of the Contact zone to form a metering and scattering opening at least partially removable are. This enables the property of the whole portions mentioned above pointy or scattered removal of the content.

The invention also includes a method for filling and closing the bag-like container, in which an approximately square, rectangular or polygonal Cutting by merging two first neighboring and one common Pointed edge sides formed into a round or square funnel and through Connection of the merged edge sides a closed only on the top Funnel-shaped open coat is formed. The container becomes via this jacket opening filled, and by folding or folding in further adjacent edge sides, by such as halving them, feeding their common limit point to the previous one formed edge sides and cover this with the section forming the bottom and subsequent connection of these, the container base can be formed.

Also a reverse order, which means that after the formation of a round or angular funnel, its edge side halves bent or into two contact zones are bent and only then is the funnel-shaped interior filled and then the connection of the contact zones to firm bottom sealing edges, such as described above is made.  

Through these processes, container formation and filling or dosing become like this made or separated from each other so that they cannot influence each other, as is the case, for example, with the prior art shown, where the cut size depending on the z. B. Scattered cone of the product. One is not through the invention limited to solid, granular and free-flowing products only. Rather, through the bag-shaped containers also contain liquid and flowable substances, because the product in the trough-shaped container with a closed jacket is filled and only the bottom, which is in the uppermost position, to is closed. Of course, the necessary ones are also in this filling process Observe free spaces so that the contact zones are not contaminated with product particles and thus not adversely affect the connection quality of the sealing edges.
