Description

Method of using a drainage bag, drainage bag and use of such drainage bag

The present invention relates to a method for using a drainage bag comprising at least one product chamber and at least one liquid chamber, wherein the product chamber and the liquid chamber are connected to each other by drainage holes formed in a partition separating the two chambers. The invention further relates to a drainage bag for use in a method of storing products which are desired to be stored under liquid. Furthermore, the invention relates to the use of the drainage bag.

Prior art

Packaging, such as bags, glasses and buckets for storing food products, is widely known and is both a convenient, easy and hygienic way of storing, transporting and selling food.

In addition to food, there may also be a liquid in the package, such as a layer, which is a solution comprising water or vinegar with salt or sugar, wherein the layer can both preserve and / or give flavor to the food in question.

A combination of food and cooking is known from hermetically sealed bags, for example with mozzarella, where the disadvantage is that the opening of such a bag puts the user in a dilemma, namely whether the entire contents of the bag should be used, and if not how remaining food then stored.

Foods and dishes are also known from small plastic buckets with salad cheese, cheese teas or salad toppings, where a wire basket in the bucket allows the food to be pulled out of the packaging. Thus, the user has the opportunity to drain the product as the layer remains under the wire basket, and the user can thereby take the part of the product that the user wishes to use and place the wire basket in the packaging again with the remaining foods submerged in the layer. The disadvantage here is that the packaging fills the same regardless of the amount of food contained in the packaging.

It is known from EP 3,184,455 A1 and from EP 0,275,350 A2 a drainage bag comprising a product chamber and a liquid chamber, which product chamber and liquid chamber are connected via drain holes formed in a partition separating the two chambers. Such bags are suitable for storing products which are desired to be stored under liquid.

There are no instructions in the aforementioned writings on how the drainage bags can be filled. Also, no explanation is given as to how these drainage bags are suitable for a user to take out a desired amount of products without getting an unwanted liquid and then continue to use the drainage bag to safely store a remaining quantity of liquid products.

The object of the invention

SUMMARY OF THE INVENTION It is an object of the invention to provide a bag for products which are desired to be stored under liquid and in which the bag makes it possible to separate products and liquid. It is in one aspect of the invention to provide a bag for products in the form of food, wherein the foods, for example cheese, are stored together with a liquid, for example, layers, where the bag makes it possible to separate food and liquid by simply positioning the bag, so that the liquid runs away from the food and thus allows the user to extract the desired amount of food without getting the unwanted liquid with and without having to handle other packaging, such as an inserted wire basket.

It is also an object of the invention that the bag can be resealed and can remain close during the reseal and thus can also be safely stored in any position, standing as lying down.

It is also an object of the invention that the bag can be positioned by means of a stand-up part so that both products and liquid remain in the bag, even if the user no longer positions the bag himself.

In addition, it is an object of the invention to ensure that the bag fills less the smaller amount of products contained in the bag.

Finally, it is an object of the invention to provide the bag with fuses indicating whether the bag has previously been opened or whether the bag is in the form with which it left the manufacturer.

Although the bag according to the invention can be used for all products which are desired to be stored under liquid and where it is desired to be able to separate the product and the liquid in order to be able to withdraw an amount of the product without getting unwanted liquid, the invention will primarily be aimed at food .

Description of the Invention

According to a first aspect of the invention, the above-mentioned object is achieved by a method for using a drainage bag comprising at least one product chamber and at least one liquid chamber, the product chamber and the liquid chamber being connected to each other by means of drain holes formed in a partition separating the two chambers, the method comprising the following steps:

- the drain bag is supplied with liquid and a number of products,

- position the drain bag with the product chamber above the level of the liquid chamber,

- the liquid passes through the drainage holes into the lowest-lying liquid chamber so that the product chamber does not contain liquid,

- the drain bag is opened,

- a quantity of products is taken out and / or a quantity of products is placed in the product bag of the drainage bag,

- the drain bag is closed,

- the drain bag is closed, and

- the liquid flows through the drain holes into the product chamber so that the products are enclosed by the liquid.

The drain bag for use in a method according to the invention for storing products which are desired to be stored under liquid is characterized in that the drain bag comprises at least one product chamber and at least one liquid chamber where the product chamber and the liquid chamber are connected by means of drain holes. which is formed in a partition separating the two chambers and that in the area at the opening of the drainage bag there is a bagglucan arrangement as well as orifice edges comprising edge strip areas prepared with a number of holes or corresponding star perforations.

The use of the drainage bag for storing products in the form of food is done by the fact that the food is food products, preferably dairy products, which are stored in a liquid.

This allows the drain bag to be filled while it is securely and accurately held in a filling station. This occurs while the bag mouth edges are used to drive the drain bag or a series of drain bags through a filling station.

The liquid and the products do not necessarily need to be filled in the bag by filling liquid before products. This can be done simultaneously or the products can be introduced into the bag before the liquid.

The invention has been developed in connection with food; but the benefits obtained with the drainage bag will also be obtained in connection with other products.

After a bag has been filled, it is possible to separate the products and the liquid by simply positioning, holding or positioning the bag so that the liquid runs away from the products. In practice, the bag is held or positioned so that the liquid flows through the drainage holes and down into the lower chamber, called the liquid chamber, after which the products remaining in the product chamber will be provided in a drained state and can thus be easily removed from the bag. without any liquid.

The drainage holes may be provided in the form of the openings in a mesh which constitutes a partition separating the two chambers.

Alternatively, the drain holes may be provided as openings in a foil forming a partition between the two chambers.

If the bag is only partially emptied, the bag - after the user has taken out the quantity of products desired - can be re-closed. Thereafter, the bag can be placed lying down so that the liquid flows back from the liquid chamber to the product chamber, whereby the product is covered by the liquid. Thus, the remaining part of the product can be stored under liquid. By re-closing the bag, it can be "vented" so that the re-sealing bag is largely or completely free of air, thereby ensuring that the remaining part of the product does not come in contact with air and consequently the risk of deterioration.

In a further aspect, the present invention relates to a process which is characterized in that the method comprises the following steps:

- the drain bag is provided in the form of a bag web which is connected via border strip areas, and

- after filling the drain bag with liquid and a number of products and closing the drain bag, the edge strip areas are cut so that individual drain bags appear, which cut optionally occurs before or after the drain bags have been laid.

In a further aspect, the present invention relates to a method for using a drainage bag as defined in claim 1 which is filled by a method according to claim 1 or 2, and which is characterized in that the method comprises the following steps:

- the drainage bag containing a quantity of liquid and a quantity of products is positioned with the product chamber above the level of the liquid chamber,

- the liquid passes through the drainage holes into the lowest-lying liquid chamber,

- the drain bag is opened,

- a quantity of products is taken out and / or a quantity of products is placed in the product bag of the drainage bag,

- the drain bag is closed,

- the drain bag is closed, and

- the liquid flows through the drain holes into the product chamber.

Hereby, the present invention provides a possibility for a full or partial emptying and full or partial refilling of the drain bag. Thus, this is not a drainage bag which is to be used solely to drain and remove the liquid from the products in the drainage bag. In contrast, the liquid must simply be removed from the product chamber so that the liquid stays in the liquid chamber while introducing or removing products from the drain bag. Before closing the drain bag, the liquid can flow back to the product chamber through drain holes so that the products are enclosed by the liquid.

The present invention also relates to a drainage bag, in which in the area at the opening of the drainage bag there is a bagglucan device which according to a further aspect is, for example, a zipper.

This allows the bag to be closed and ensured that the bag can remain close during the closure and thus can also be safely stored in any position, standing or lying. As mentioned, this also ensures against air access to the product.

The present invention also relates, in a further aspect, to a drain bag where, on the side of the bag glucan device closest to the opening, there is a bag disposable fuse indicating whether the bag has been opened.

This allows the user to feel safe knowing whether the bag containing the products has been opened by others before or whether the user is the first to open the bag since leaving the manufacturer. For example, there may be a full weld, partial weld or a perforation line to be torn or cut to access the bag gluing device. For example, the bag gluing device may comprise a zipper closure.

The present invention also relates in a further aspect to a drainage bag, the drainage bag comprising a stand-up part.

This allows the bag to be positioned without the user having to hold it in his hand or line it up with anything, but where the user can simply position the bag on its stand-up part.

In a further aspect, the present invention also relates to a drain bag in which the stand portion is collapsible.

This allows the bag to be transported without the stand-up part being folded out, and it also allows the bag to be kept lying down with the folded-up part, whereby the bag will thus fill slightly smaller or at least easier to fit in a refrigerator when the stand-up part is not folded out.

In a further aspect, the present invention also relates to a drainage bag in which, on the side of the stand-up portion opposite the product chamber and the liquid chamber, there is a bag disposable fuse indicating that the stand-up portion has been folded out.

This allows the stand-up part to be collapsed from the manufacturer and until the bag comes home to the customer or perhaps until the time when the user wants to use all or part of the bag's contents.

In contrast to the bag locking device by the bag-closing device, this bag locking device in the stand-up section does not give the user any assurance as to whether the bag has been opened by others before or whether the user is the first to open the bag since leaving the manufacturer. Here, the fuse may be a full weld, partial weld, or a perforation line that must be torn or cut open to access the stand-up section.

In a further aspect, the present invention also relates to a drainage bag, wherein the drainage bag is a pillow bag with means for conversion into a stand-up bag.

This makes it possible to distribute the contents of the bag relatively uniformly and evenly in the bag when the bag is lying down and when the contents of the drainage bag are to be used in whole or in part, the weld is separated from the other bag by tearing along the bag disposable fuse, whereby the drainage bag's stand-up part can be used, whereby the bag goes from a pillow bag to a standing bag.

The present invention also relates in a further aspect to a drainage bag, in which in the area of the drainage bag opening there are mouth edges comprising edge strip areas prepared with a number of holes or corresponding star perforations intended to be guided with guide means which are arranged to maintain and fabricate peripheral areas at the opposing bag mouth edges along a conveyor path through a filling station.

This allows the drainage bag to interact with guide means which can hold and drive the bags along a conveying path through a filling station. This also allows safe, simple and quick filling of the drain bag.

In practice, the drain bag in this embodiment will typically be formed as a continuous web of bag items. This bag blanket is continuous through the edge strip areas. After filling the drain bag, a closure will be established below the edge strip area, preferably by welding the opposite sides of the drain bag, and the edge strip areas will be cut off to provide individual drain bags.

The invention is also directed to a method of using a drainage bag, as well as the use of a drainage bag for storing food, the foods being preferably dairy products.

Alternatively, the drain bag can be used for other food products stored in a liquid, such as olives.

The drain bag can also be used for other products that are desired to be stored under liquid and where you want to be able to drain the liquid away from the products before the products are removed from the drain bag.

Detailed description of the invention

A drain bag for storing foodstuff products according to the invention is shown in Figures 1-7. The bag can also be used for storage of other products.

Figure 1 shows a front view of a drainage bag 1 in which the drainage bag 1 comprises a product chamber 2 and a liquid chamber 3 which are connected to each other by drainage holes 4 formed in a partition 12 separating the two chambers 2.3 , which is formed in the interior of the bag. The drain holes are shown in Figure 1 as three large holes, but in practice can be very small holes.

The partition 12 may alternatively be a mesh.

The figure also shows that in the area at the opening of the drain bag 5 there is a bag hatch device 6 and that on the side of the bag hatch device 6 which is closest to the opening 5, there is a bag closure 7 which indicates whether the bag has been opened.

The bag gluing device 6 is preferably a zipper.

The bag disposable fuse 7 is preferably a weld.

It can also be seen from the figure that the drain bag 1 comprises a stand-up part 8 which is collapsible and that on the stand-up part 8 opposite product chamber 2 and liquid chamber 3 there is a bag disposable fuse 9 which indicates whether stand-up part 8 has been folded out. The idea is that under the bag disposable fuse 9, which is preferably a perforation, there is an additional weld 13 which ensures that the bag retains the cushion shape, thus the bottom fold cannot be "knocked out" and form a chamber. In the figure, bag locking device 9 is unbroken and therefore the stand-up part 8 has not previously been folded out / knocked out.

Figure 2 shows a side bag drainage bag 1, indicating that the drainage bag 1 is a pillow bag 10.

Figure 3 shows a front view of a transparent drainage bag 1, in which it is further shown that the drainage bag 1 contains food 11. The bag is shown here as being transparent to also show the foods 11 in the bag, but the bag will often be opaque, partly due to advertisements and content descriptions and partly because the food 11 is not wanted to be exposed to unnecessary light.

Figure 4 is a front view of a drainage bag 1 in a standing bag form where the bag disposable fuse 9 for the stand-up part 8 is broken. The weld 13 is thus torn off in the perforation 9, and the bag can thereby be unfolded thereby forming a flat bottom (the bottom fold unfolds) and thereby increasing the volume of the liquid.

Figure 5 shows a side bag drainage bag 1 in which the bag disposable lock 9 for the stand-up part 8 is broken and where the stand-up part 8 is folded out and where the drain bag 1 can stand up.

Figure 6 shows a drainage bag 1 in the standing bag form as in Figure 4, but where the drainage bag 1, seen from the front, is transparent and containing food 11.

Figure 7 shows a drainage bag 1 having in the area at the opening of the drainage bag 5 orifice edges 14 comprising edge strip areas 15 which are prepared with a series of holes 16 in guide communication with guide means 17 arranged to hold and guide edge areas 15 at the opposing bag mouth edges 14 along a conveying path through a filling station.

In Figure 7, only one drain bag 1 is shown, but in practice a bag web will be provided which is continuous through the edge strip regions 15.

After filling the drain bags, a closure / welding of each drain bag 1 will be established under the edge strip area 15. The edge strip areas 15 are then cut so that individual drain bags 1 appear.
