NL1017397C1 - Production of sachets for powder materials, comprises folding one edge and sealing other edges tight after filling the sachet with material - Google Patents

Abstract

A strip of material is folded to form a folded edge (2), then at least two opposing edges (3, 4) are sealed tight, and then after adding the contents, the remaining open edge (5) is also sealed tight. The closed sachet (1) is then cut to the desired dimensions. The production of sachet-type holders, preferably for small quantities of powder materials, comprises forming a rectangular sachet from a strip of sealable material. The strip comprises at least one layer and is folded in a specially designed machine so that one edge of the sachet is folded, and then at least two opposing sides or edges are sealed tight. The sachet is filled via the open side, which is then sealed tight, and the closed sachet is cut to the desired dimensions. A means (7) for hanging the sachet can optionally be provided. An Independent claim is also included for a sachet made by this method, comprising a multi-layer sealable material optionally containing an aluminum barrier layer and optionally containing a paper or plastic layer for printing on.

IMPROVED SACHET

The invention relates to a method for manufacturing improved sachet-shaped containers and the improved sachet itself for usually receiving powdered substances and usually in small quantities, said sachet-shaped container or sachet usually being manufactured in rectangular form from a strip of material, wherein the material is sealable or sealable to each other for finally forming said sachet.

It is known that herbs are added to all kinds of vegetables, whereby a whole range of pots with the desired herbs are available for the cook or cook.

The problem arises that the cook or cook in question must himself determine the quantities and the mutual ratio as well as the choice of the herbs or ingredients. This is an extremely difficult matter for most dish preparers, as a result of which too much or too little of certain herbs or even wrong herbs are added, or appropriate herbs are omitted. In short, the cooking art of very many people who stick to cooking object to the later users of the meals.

If herbal bags or sachets are available, for example, one does not have a suitable quantity and composition supplied for a certain quantity of vegetables, which quantity is associated with said quantity of vegetables. In short, the known method and the provision of herbs in bags or sachets have a number of drawbacks for the consumer, in this case the cook or cook.

To this end, the method for manufacturing the sachet and the sachet has been further developed in a very inventive manner such that as starting material a strip of said sealable material is built up from at least one layer, wherein said strip of sealable material is used in a suitable machine. is folded and thus forms an edge and is subsequently sealed at at least two opposite sides or edges, then filling of the rectangular sachet takes place with the substances to be taken up in said suitable machine, after which the last side or edge is sealed and the shaped sachet is then cut off gracefully, user-friendly and conveniently attachable with the dimensions L x W for use, wherein a suspension element may be provided for fixing.

The advantage is a very user-friendly sachet that is directly linked to the relevant vegetable, fruit or plant.

Furthermore, the sachet according to the invention has been further developed in such a way that the sealable material is built up in layers, whereby for reasons of impermeability an aluminum layer may have been added, and a paper or plastic layer may have been added for external printing, wherein the layer structure of the sealable material can be as follows:

- Paper / PE / Alu / PE

- Paper / PE

- PET / PE / Alu / PE

- Polyester / PE / Alu / PE

30 - LDPE

- PET / LDPE or PE

- PP or OPP whether or not laminated with PE

- PET / LDPE

- PVdC coated PET / LDPE

35 - Polyester / PE

- PA / PE

- PET / PE / EVOH / PE

- PVC / PE

The advantages are excellent sachets, in which the herbs, powdered mixtures and the like remain fresh and are readily available.

Furthermore, the sachet according to the invention has been further developed to such an extent that one of the corners is provided with a molded-on suspension element in the form of a hook consisting of a centrally punched hole with circular sealing edges all around, a cut line may be intersected, wherein said sachet can thus be hooked on stems of vegetables, fruit and plants.

The advantages are that the strongly improved sachet cannot damage the vegetable or fruit and that it can be easily connected to the product.

The invention is explained in more detail below with reference to a preferred embodiment shown in the drawing. Hereby shows:

FIG. 1 is an elevated view of the improved sachet in accordance with a preferred embodiment of the present invention.

Figure 1 shows a preferred embodiment of the improved sachet 1 in view. The jacket or the improved sachet 1 is folded at the edge 2 and sealed at the edges 3, 4 and 5. The sealing is indicated by the dashed lines 6. During the filling process, the sachet 1 is filled via the open edge 5, which is sealed immediately afterwards. A suspension hole 7 is provided on the edge 2, which is connected to the edge 2 with a cut line 8. Circular dashed lines 9 are provided around the suspension hole 7 for sealing. Furthermore, in order not to damage the vegetables or fruit, for example, the corners 10 are rounded. In addition, texts are placed on the sachet for advertising and on the reverse side (not shown) the weight and the ingredients intended for a specific weight of vegetables or fruit and the like with an expiry date and the like are stated.

As stated in the claims, the material for the sachet is made up of layers to guarantee the quality and printability of the sachet. An example of layer structure (claim 3) is Paper / PE / Alu / PE, wherein the Aluminum layer guarantees the density of the improved sachet, so that no diffusion of vapors can take place. The dimensions of the improved sachet, namely L x W, are approximately 50 to 60 mm.

Finally, it should be explicitly stated that a preferred embodiment for a sachet for herbs has been described above and that further modifications are possible without departing from the scope of protection of this patent.
