Description

The present invention relates to the field of packaging, in particular to bags with dispensers intended for placing bulk materials in them, with the possibility of pouring out the contents of the bag through the lower part. The inventive package can be used for the sale of bulk and granular materials, for example, plant seeds, fertilizers, de-icing reagents, etc.

Currently, packaging in the form of various types of bags, bags, and boxes is widely used for carrying bulk materials. In such packaging, thanks to the pouring hole, it is easier, in particular, to pour out part of the contents. To carry out the pouring, it is necessary to lift the filled package and tilt it so that the contents can pour out through the pouring hole, which is usually located in the upper corner of the package. In particular, with bag-shaped packages, the heaviness of the contents makes it difficult to pour out, especially the desired small quantities of product.

To make it easier to pour the product out of the boxes, it is suggested to use “spouts” of various designs.

Packaging is known (1 - patent RU 2196090 “Packaging for bulk products”, published on January 10, 2003 Bulletin No. 1), made in the form of a box with side and end walls, as well as a bottom and a lid. An opening outlet hole is formed on one of the walls, behind which, on the inside of the package, is attached, for example, using a circular adhesive joint, a strip of packaging material, which is also opened, if necessary, partially along a perforated or similar weakened line, and pulled out of the hole in a narrow side wall to obtain a “spout” type pouring device.

The disadvantage of this solution is the complexity of the design of the “spout” intended for pouring out the contents of the package, the difficulty of opening and closing it, and also the fact that packaging in the form of a box is less convenient to use than a bag or bag, which allows you to reduce the volume they occupy to almost the volume of the product stored in them, despite the fact that they can be given almost any shape.

Numerous bags are well known, made of polymer, often laminated, film, the two walls of which are connected by heat sealing. One-time closure of the package (that is, without the possibility of re-closure after opening) can be accomplished by stitching, taping or other means, soldering or ultrasonic welding after filling the container with the product.

The design of a bag is known (2 - application US 20080240626 A1 “Bag construction with side gussets”) with side folds for filling with bulk material. The bag has panel sections and side gusset sections, as well as a bottom panel section. The different sections of the panel are fastened together to form an overall rectangular shape with a flat bottom. The bottom section of the corner panel has one or more distribution holes. A removable panel layer is provided to cover one or more holes. When the release panel layer is removed, the bag can be held so that the material disperses through the holes.

A disadvantage of the bag design [2] is the inconvenience of storing the remainder of the bulk material after use.

A bag is known (3 - patent US 8277121 B2 “Bag construction with flat bottom having removable layer”), designed for filling with bulk materials, while the bag has a flat bottom with holes and a removable layer that covers the holes before use.

The disadvantage of the bag [3] is the inconvenience of using a removable layer for reusing the remainder of the bulk material, as well as insufficient reliability during repeated opening and closing.

Packaging is known (4 - patent US 9782946 B2 “Laminate structure with access openings”, published 10/10/2017), which refers to the configuration of a laminated structure that allows layers to be peeled off to expose access openings using a more uniform peel force. The package may contain a granular product, and may be configured to facilitate dispensing of the contents of the package.

The disadvantage of packaging [4] is the complexity of the layered structure, which is reflected in the price, and the inconvenience of using the packaging.

There is a known package (5 - patent RU 117139 “Packaging with a dispenser”, published on June 20, 2012 Bulletin No. 17), containing a package equipped with a dispenser with calibrated holes, manufactured integrally with the package and built into the inside of the package on the side intended for opening along the separation line.

The disadvantage of such a package [5] is its low functionality, limited possibilities for transportation and storage of the unused remainder of the product.

Recently, manufacturers have made attempts to use bags that have elements that make them re-closeable. The means of resealing the bag prevents the product remaining in the package from spontaneously spilling out.

The bag material and its closing element are, as a rule, selected for reasons of maximum economic efficiency, namely the optimal combination of the properties and cost of the bag material, the properties and cost of its closing element. Some manufacturers have tried to solve the problem of pouches tearing at the reusable closure element by using a reusable closure element with twice the thickness of the material. However, as additional elements are introduced into the design of the package, its cost may increase to an unacceptable level.

The closest technical solution to the claimed invention in terms of the totality of essential features is a utility model (6 - patent RU 187877 “Packaging with a zip-lock fastener”, published 03.21.2019 Bulletin No. 9), adopted as a prototype, in which a zip-lock fastener , is made integral with the bag and a built-in dispenser at the top of the bag. The bag has upper and lower tear-off parts along the tear line with notches and a zip-lock fastener built above the dispenser.

The disadvantage of the prototype [6] is the lack of reliability during operation, the likelihood of the package breaking and its contents spilling out, and there is no provision for a holding device that forms a handle, which places increased demands on the strength of the shell material and limits the mass of the loaded bulk material.

The disadvantages of the known technical solutions are the difficulty of uniformly dosed pouring out products of a heterogeneous fraction, in particular, de-icing reagents, plant seeds and fertilizers.

The technical problem to be solved by the proposed technical solution is the creation of a package that simplifies the uniform dosed pouring of bulk materials of a heterogeneous fraction on the target area and its repeated use, as well as expanding the arsenal of technical means.

To solve this technical problem, a package with a dispenser for bulk materials is proposed, containing a lower tear-off part along the tear line with notches, a built-in dispenser with perforated holes, and a zip-lock fastener built into its inner part.

According to the invention, the dispenser is built into the lower part of the bag and is made in the form of a perforated partition with alternating holes with a diameter of 3 mm, 5 mm, 7 mm and their quantitative ratio, %: 50, 25, 25, respectively, with the ability to produce uniform dosed pouring of the contents of the bag, Below the dispenser there is a built-in zip-lock fastener, under which there is a tear line with notches, and a carrying handle is built into the upper part of the bag.

And also, in a private version, the package can be made multilayer. The handle can be made in the shape of a rectangle with rounded edges. Inside the rectangle of the handle there is a hole for fingers in the shape of, for example, a horizontal letter "C" with a wavy top edge. The handle can be made in the shape of a circle, oval, crescent, a slot located horizontally in the shape of a D, the dispenser can be made in the shape of a rectangle, or a circle, or an oval, etc., that is, have any shape depending on the cross-section of the bag. A bag with a dispenser for bulk materials can be used for sowing seeds in the soil or for fertilizing the soil with bulk fertilizers, or for treating surfaces with de-icing reagents.

The proposed technical solution is aimed at obtaining a technical result expressed in expanding the arsenal, increasing functionality, simplifying the uniform dosed pouring of bulk materials of a heterogeneous fraction on the target area, creating a package that is easy to use and carry, while preserving the unused remainder of its contents.

In fig. 1 shows a general view of the package.

In fig. Figure 2 shows an example of a package diagram with a dispenser for bulk materials.

In fig. Figure 3 shows an example of a built-in dispenser with perforated holes.

The following notations are used in the figures:

1 - package;

2 - handle;

3 - dispenser;

4 - zip-lock fastener;

5 - tear line with notches;

6 - perforated holes.

Shown in FIG. 2, the preferred design of package 1 with dispenser 3 for bulk materials consists of a front and rear wall with side seams connected by any of the known methods, for example, by gluing or soldering along the side edges of the walls.

A handle 2 is built into the upper part of the package 1. The handle 2 can be made, for example, in the shape of a rectangle with rounded edges, inside of which there can be a hole for fingers, for example, in the shape of a horizontal letter “C” with a wavy upper edge.

Thanks to the presence of the hole, the bag 1 can be held with one hand, which makes it easy to carry its contents. Handle 2 can have different shapes, for example, a circle, an oval, a crescent, a slot, a horizontal letter D.

The handle 2 can be made with a reinforcing strip, for example, of a thermoplastic material, adjacent to the inner surface of the walls of the bag 1, where the handle 2 and sections of the reinforcing strip are hermetically connected to each other at the hole, for example, by heat sealing or a layer of adhesive. Such a handle 2 with a reinforcing strip has sufficient strength to prevent rupture of the material of the bag 1.

A dispenser 3 with perforated holes 6 is built into the inner lower part of the bag 1 (Fig. 3). The dispenser 3 can be manufactured, for example, integrally with the package 1 or be, for example, soldered or glued into it. The dispenser 3 can have any shape depending on the cross-section of the package 1, for example, rectangular, round, oval, etc.

The perforation is made in the form of through holes of different diameters, applied in rows over the entire area of the dispenser 3. The diameter of the through perforated holes 6 is 3, 5 and 7 mm, which in percentage terms is %: 50, 25, 25, respectively. This makes it possible to produce dosed pouring of a heterogeneous fraction of the contents.

Bag 1 contains a zip-lock fastener 4, which can be made, for example, integrally with bag 1, or be, for example, soldered or glued into the walls of its inner lower part. Zip-lock fastener 4 is a reusable closure element, an airtight lock that closes tightly using a rib inserted into the groove.

Bag 1 has a lower tear-off part along the tear line with notches 5, located below the zip-lock fastener 4, for opening bag 1 from the bottom.

In particular, a preferred embodiment of the present invention concerns a bag with a dispenser for bulk materials of a heterogeneous fraction, for example, plant seeds, fertilizers, which is used as follows.

Bag 1 has two walls - front and back, with side seams, forming an internal volume for containing bulk material.

To empty the contents from bag 1, the user must open bag 1 from the bottom. To do this, it is necessary to tear off the lower tear-off part along the tear line with notches 5. After this, open the zip-lock fastener 4 by disengaging the elements of the zip-lock fastener 4. As a result, the perforated holes 6 (Fig. 3) of the dispenser 3 are exposed, and through them by shaking Some of the contents of package 1 spill out.

Due to the fact that the perforated holes 6 are made of different diameters, a more uniform dosed extraction (scattering) and consumption of bulk material having a non-uniform fraction occurs. This expands the possibility of using the bag for bulk materials with different particle sizes.

After removing the dose of bulk material, close the zip-lock fastener 4 to prevent further spilling of the contents of the package 1 through the perforated holes 6 and its contact with the environment.

Bag 1 can be easily reopened by releasing the zip-lock elements 4. The operations can be repeated several times, pouring out the contents in stages, closing bag 1 and storing the bulk material for later use.

Thanks to the existing handle 2, the package 1 is convenient to carry in your hand.

Another application of the present invention may be for other products, such as de-icing agents.

In the examples, a bag measuring 30x46 cm was used.

Example 1. Using a bag with a dispenser for sowing seeds in the soil.

Seeds taken for sowing:

1. Lawn grass Elite / (Meadow bluegrass 10%, Red fescue 20%, Perennial ryegrass 20%, Meadow fescue 50%). Manufacturer JSC SSPP Sortsemovoshch, St. Petersburg.

This lawn grass is a grass mixture with different seed sizes.

The height, width and depth of the package determine its internal volume, which is at least 20% greater than the volume occupied by the contents, in this case the seeds, of the package, that is, there is free volume above the seeds, that is, the contents of the package do not occupy all of it internal volume. The presence of approximately 20% empty volume allows the bag to be easily and securely sealed after filling. When the dispenser was perforated in the ratio: 3 mm - 50%, 5 mm - 25%, 7 mm - 25%, there were 9-10 shakes (15 grams) per 1 ^m2 . One shake covers an area of 0.1 ^m2 (1.5 grams). Accordingly, a 1.5 kg package is enough for 100 ^m2 of sowing.

A bag with a dispenser made in the form of a perforated partition with alternating holes of different diameters allows for uniform distribution of seeds of different sizes. For example, meadow fescue seeds have a 5-7 mm seed, and meadow bluegrass has a 1-2 mm seed. Accordingly, the small diameters of the perforation will be partially blocked by large seeds, which will prevent the rapid spilling of small bluegrass seeds, thereby allowing for the most even and dosed sowing of seeds of different crops.

It is also possible to mix lawn seed with lawn fertilizer to obtain high quality lawns with a uniform texture.

2. Root celery, Apple variety. Brand "Seeds of Altai".

For planting celery seeds, a method was used that greatly facilitates planting small seeds in open ground - sowing seeds mixed with sand. The sand was taken fine, dry, sifted. Its volume exceeded the total number of seeds in a ratio of 4:1. In order for the seeds to germinate faster, 20 g of wood ash was added to the mixture of sand and seeds. The prepared mixture was packaged in a bag and sown in open ground. The seed consumption during planting was 0.5 g per surface area of 20x20 cm.

As a result, a uniform distribution of seeds was observed over the entire planting area due to the different sizes of the diameters of the dispenser holes.

Example 2. Using a bag with a dispenser to fertilize the soil with bulk fertilizers.

The mineral fertilizer Azofoska, produced by Khimaktiv, was chosen as a fertilizer.

Azofoska is a granular, friable powder of gray-pink color with a particle size of 2 to 4.5 mm. When the dispenser is perforated in the ratio: 3 mm - 50%, 5 mm - 25%, 7 mm - 25%, there are 9-10 shakes (70-80 grams) per 1 ^m2 . One shake covers an area of 0.1 ^m2 (7-8 grams). Fertilizer was applied under potatoes - 25 g (2 tbsp) per 1 ^m2 , which corresponds to 3-4 shakes per 1 ^m2 .

Also, as in example 1, a uniform distribution of fertilizer granules was observed throughout the entire treated area, due to the different sizes of the diameters of the dispenser holes.

Example 3. Using a bag with a dispenser for treating surfaces with de-icing reagents.

To treat the icy surface of the earth, the de-icing reagent IceCare CLASSIC, manufactured by FERTIKA, Russia, was used. The surface treatment was carried out with an ice thickness of 2 mm. The deicing agent was evenly scattered onto the surface to be treated, through the perforated holes of the bag dispenser by shaking. The reagent consumption was about 200 g per 5 ^m2 . We needed 50 shakes per 5 ^m2 . One shake covers an area of 0.1 ^m2 (4 grams). Accordingly, 1 package of 5 kg is enough for 125 ^m2

In this case, package 1 can be made multilayer. Inside, it may contain an additional inner layer (not shown in the figures), intended for direct contact with bulk material, made, for example, of polyethylene film, which provides moisture protection for hygroscopic materials poured into the bag and increases its mechanical strength.

As follows from the experimental studies described in examples 1-3, a bag with a dispenser made in the form of a perforated partition with alternating holes of different diameters allows for uniform dosed pouring of the contents of the bag, as well as uniform distribution of granules/seeds of different sizes.

Also, the shaking method allows you to mix the contents of the bag, which during long-term storage can “cake” and separate by size, that is, separation of mixed volumes of dissimilar particles occurs (small seeds/granules can fall to the very bottom, thereby being separated from large ones).

At the same time, each of examples 1-3 showed stable retention of the dosage and uniform coverage of the target area with the poured contents of the bag, regardless of the intensity of its shaking, which confirms the achievement of the technical result expressed in the simplification of the uniform dosed pouring of bulk materials of a heterogeneous fraction on the target area. The dosage error when shaking the bag with different intensities was no more than 10% of the average values.

Uniform dosing allows you to indicate on the bag the amount of poured contents in grams per shaking for each type of fertilizer or seed, which increases the user’s convenience to navigate when carrying out sowing work for different crops or fertilizing the soil.

Although specific preferred uses of the present invention have been described in connection with non-food products such as deicing agents, plant seeds and fertilizers, the present invention is in no way limited to the use of such products. Applications of other products include, for example, cleaning products, sand, dry construction mixtures or food products - cereals, flour, sugar, salt, etc.

Bag 1 can be made of any material, for example, foil, plastic, polyethylene, polypropylene fabric with high mechanical tensile strength. The thickness and type of material are chosen mainly depending on the expected mass and the purposes for which package 1 is designed.

Bag 1 is convenient to use and allows you to store the remaining bulk material in it for later use.

A significant advantage of Package 1 is its ease of use. This package is convenient to use at home and other household conditions.

In its specific design, the package is designed for the use of bulk materials with a heterogeneous fraction, but it is also applicable to bulk materials with a uniform particle structure. This invention expands the possibilities of using packages.

This ensures the achievement of the above technical result in the form of expanding the arsenal, increasing functionality, simplifying the uniform dosed pouring of bulk materials of a heterogeneous fraction on the target area, creating a package that is easy to use and carry, while preserving the unused remainder of its contents.
