Technical field

The invention relates to a packaging bag. It also relates to a method of applying a consumer product to a food product or body, as well as the use of such a packaging bag for distribution or for offering the consumer product for sale.

Prior art

Consumer goods, which are used in relatively small quantities, are usually packaged, for example, in the form of unit doses. Packaging used for this purpose may be, for example, a bag or box. Batch packaging, in particular, but not exclusively, is used when consumer goods are intended for the professional use market. Examples of portions of consumer goods are bags with sauce, such as mayonnaise, ketchup or soy sauce, bags of salad dressing, bags of personal hygiene products such as skin cream or shampoo. In the case of food products, such products may be served by the restaurateur after the ordered food. Personal care products, for example, can be provided by a hotel or a company that packs a typical format or road format packaging.

As for packaged food products, in this context it is obvious that consumers have different preferences when combining the contents of a portion of the package with their food. One group of consumers prefers to dip pieces of food, such as french fries, separately into sauce, for example, in ketchup or mayonnaise before eating these pieces of food. For such consumers, the most preferred packaging option is a box, often conveniently closed with an airtight lid. Examples of portion boxes are butter or margarine containing boxes, or fruit jams. Other consumers, not wanting to use the sauce several times, prefer to dress the food or dish with the sauce and then consume the dish. In the latter case, the contents of a portion package are often completely poured or squeezed out of the package. For such consumers, the most preferred is a packing bag in the form of a tube. A packing bag in the form of a tube is a tube of flexible material, such as foil or paper, which is usually hermetically sealed at both ends.

As for the packaged personal care products, in this context, consumers also prefer to use portion packs. Some people prefer to pour part of the contents of the package or the entire contents of the package on any part of the body or on the arm, and then distribute it throughout the body. Others prefer to dose a personal care product, such as a cream, based on the amount on the finger when they touch the product. These preferences may obviously depend on the type of product.

To meet these differing consumer preferences, it is desirable to have a packing bag that can be used in situations where emptying by extrusion is preferred ("extrusion format"), and in situations in which packaging should provide access to relatively large quantities of food or for fingers, which must apply to the product contained in the packaging bag (“dipping format”).

The problem with the ordinary bag in the form of a tube is that it does not allow dipping. In addition, the sachets in the form of a tube contaminate the table after use. To effectively empty the bag in the form of a tube, you need to use two hands: with one hand hold the bag in the form of a tube, and the other squeezes its contents from one end to the open end. In a situation where only one hand is free, while the other holds, for example, a fork, this can be inconvenient. And, finally, a relatively large amount of packaging material is used in a tube in the form of a tube compared with the amount of product it contains.

The problem with portion packs is that it is not so easy to empty the package and distribute its contents to the food or body. Content sticks to packaging. Packaging in the form of a box is usually made of rigid material, which does not allow it to be emptied by squeezing. Another disadvantage is the use of different materials for the box and airtight lid, which can lead to additional costs, additional process steps and / or increased environmental impact.

From the prior art several packages of various shapes are known. Such packagings are not used as portion packs for consumer goods, but, for example, used as reusable containers or in any other manner different from the packaging bag of the invention. Such packages do not have the advantages characteristic of the packaging bag according to the invention, i.e. does not provide the possibility of both "extrusion format" and "dipping format".

JP 08318971 describes a fluid packaging container in the shape of a tetrahedron with two opposite ribbed edges made by heat sealing. At one end of one of the edges, an unsealed fluid discharge opening is provided.

pyramids. The upper part of the pyramid can be cut off along the slot and the tear line.

WO 03064265 discloses a package container having an upper side part and a lower part bounding the body of a tetrahedron. The top side and bottom are sealed with a vertical welded joint.

In the document US 6409386 disclosed container for liquids or flowing products. Two mutually opposite quadrangular surfaces are sealed along successive sides, while the third side of each of the two surfaces is connected by an accordion section, which forms the essentially triangular base of the container, and the fourth side has an additional section in the form of an accordion, which forms the closing wall. The container has a filling hole on one of the two first sides or at the corners where they converge.

There is a need for a packaged portion bag for liquid or pasty consumer goods, which allows emptying it by squeezing and opening it in such a way that it is possible to dip large objects in the contents of the package. Such a package is placed as naturally as possible in the hand in order to ensure efficient emptying by squeezing the contents out of the package. The package should preferably be able to stand freely on the surface and remain open after opening. Thus, it is best suited for dipping, not tipping over and thus not polluting the table.

DISCLOSURE OF INVENTION

Surprisingly, these problems were solved by means of a bag containing the bottom surface (1), the front surface (2) and two side surfaces (3), each of the bottom and front surfaces having the shape of a triangle, these triangles have a common base (4 ), and the sealing edge (5) connects the edges of the side surfaces that are not adjacent to the front or bottom surface, has a curved region (6a) and / or an angle (6b). Preferably, the angle between the front surface and the bottom surface, preferably between the front surface and the projection of the bottom surface, is obtuse.

Embodiments of the invention

A packaging bag according to the invention contains a bottom surface (1). The bottom surface is easily recognized by a person skilled in the art. It is a surface facing the surface on which the packing bag is in its natural position. The bottom surface has a triangular shape. The surface has the shape of an acute triangle, most preferably an isosceles triangle. The angle at the apex of this preferably isosceles triangle is preferably from 30 to 60 °, more preferably from 40 to 50 °. The triangular shape of the bottom surface provides a number of advantages: in the “dipping format”, the triangular base provides a stable base for the sachet, which allows the consumer to dip the components of the food product in the sachet without tilting the sachet, thereby not spoiling the table. In addition, it allows the bag to be opened when the upper part of the sealing lip is removed to provide a “dipping format” with a reduced risk of the side surfaces of the bag sticking together. Regarding the "extrusion format", the triangular shape of the bottom surface provides a natural placement in the hand. In addition, the triangular shape facilitates the effective emptying of the bag during extrusion. The bottom surface is preferably a plane. A plane is a surface that extends in two dimensions. Structurally, it is preferably not curved, forming a volumetric shape. It preferably has no fold or crease. The bottom surface may be parallel to the surface on which the packaging bag stands, but it is preferable that the bottom surface makes an angle of, for example, from 1 to 45 °, more preferably from 10 to 30 °, with the surface on which the bag stands. In a situation in which the bottom surface forms an angle with the surface on which the bag stands, the bag preferably rests on the base of the triangular bottom surface (which is the base of the bottom).

coal front surface) and sealing edges (9) adjacent to two sides of the bottom surface, directed toward the top of the triangular bottom surface. In this regard, it is preferable that the bottom surface is located between two sealing edges located on two respective sides of the triangular bottom surface, which are directed towards the top of the triangular bottom surface, and extending from the two side surfaces.

The front surface has a triangular shape. Preferably, the front surface is an acute triangle, most preferably an isosceles acute triangle or an equilateral acute triangle. The triangular shape is important for keeping the packaging bag open when the bag is used in the “dipping format” and has a cup shape after removing the top seal, which reduces the risk that the side surfaces will stick together. When a sachet is used in an “extrusion format”, the triangular shape of the front surface makes it possible to create a sufficiently wide opening that is not easy to close again and from which the contents of the packaging bag can be easily squeezed out. The latter advantage is even more noticeable when the viscosity of the bag content is relatively low, for example, as with relatively fluid products. The front surface is preferably a plane. Structurally, it is preferably not curved. Preferably it has no fold or crease. Preferably it corresponds to a two-dimensional flat surface.

The top of the triangular front surface is directed upwards. The base of the triangle forming the triangular bottom surface is connected to the base of the triangular front surface, thus the triangular bottom surface and the triangular front surface have a common base. Preferably, the angle between the front surface and the bottom surface, preferably between the front surface and the projection of the bottom surface (vertical projection of the bottom surface onto the horizontal support surface on which the bag stands when the triangular bottom surface faces the said support surface) is obtuse, preferably in range from 90 to 150 °, more preferably from 100 to 140 °, most preferably from 110 to 130 °. Under the angle between the surfaces, the person skilled in the art understands the angle between the respective intersections of the surfaces with the reference plane, which is perpendicular to both surfaces. It is clear that this angle is considered to be the angle located inside the packaging bag. Preferably, the angle (a) between the respective middle lines of the front and bottom surfaces, preferably between the front surface and the projection of the bottom surface (vertical projection of the bottom surface onto the surface on which the bag is in its natural position, that is, the triangular bottom surface facing the said surface) was blunt, preferably ranged from 90 degrees to 150 degrees, more preferably from 100 to 140 °, most preferably from 110 to 130 °. Too wide an angle increases the risk of the bag tipping over, jeopardizing the function of dipping. In addition, the aforementioned angle values provide for the natural placement of the bag in the consumer’s hand. In addition, it provides optimal distribution efficiency. For example, an angle of less than 90 ° easily leads to complications during emptying of the packaging bag by squeezing it, since the contents of the bag will soil the user's fingers. Thus, the function of squeezing the contents of the bag will be broken, which is not desirable.

The bag further comprises two side surfaces (3). Each of these surfaces preferably has more than three angles, preferably four. It may be preferable for each of the surfaces to have more than four corners. Preferably, there is an angle (6b) opposite to the angle jointly formed by the bottom surface and the front surface. The side surfaces are preferably welded to the bottom surface. The welds connecting the side surfaces to the bottom surface preferably extend further than the bottom surface, thus forming two-dimensional edges (9). This preferably V-shaped edge structure, in which the upper part V is located at the junction of two side surfaces, can provide design flexibility to help the bag stand on a flat surface. These edges, extending from the sides, may themselves each have a triangular shape to impart optimum stability to the bag when it is free. The tops of these triangles, as a rule, are located on the front side of the bag, and the bases are located on its back side.

The sealing lip (5) extends along the edges of the side surfaces that are not adjacent to the bottom surface and the front surface. The edges of the side surfaces are preferably connected to each other using this sealing lip (5) and thus limit the upper side (7) and the rear side (8) of the packaging bag. Thus, the sealing edge preferably forms a two-dimensional structure, i.e. the seam is present in one geometric plane. The sealing edge (5) preferably starts from the top of the front surface. It preferably runs from the top of the front surface to the top of the lower side.

surface. The sealing edge is preferably uniformly sealed over its entire length. Any unsealed area is undesirable, as this may entail a risk of leakage. The seam is preferably a weld seam.

The sealing lip comprises a curved, preferably convex region (6a) and / or at least one angle (6b). The angle is preferably a full angle or a blunt angle, more preferably a full angle, most preferably a full blunt angle. Preferably, the upper part (7) and the rear part (8) of the sealing lip are bounded by a curved area or at least one angle. The sealing lip preferably has an upper part (7) and a rear part (8). The back of the sealing lip extends upward from the top of the projection of the lower surface. The back of the sealing lip preferably starts from the top of the bottom surface. Preferably, the rear portion of the sealing lip extends from the top of the bottom surface to the upper right corner of the bag, as viewed from the side of the packaging bag in a horizontal direction, while the front surface is on the left. Preferably, the angle (β) between the rear part of the sealing edge and the top of the projection of the bottom surface is from 70 to 120 °. The shortest line between the top of the front surface and the back of the seam preferably forms an angle with the projection of the bottom surface from -30 to 30 °, preferably from -15 to 15 °. Thus, the upper part of the sealing lip substantially extends parallel to the projection of the lower surface. Such geometry facilitates proper emptying by extrusion. In addition, it contributes to the correct formation of the cup in the case of preference for the "dipping format", in which the consumer is offered the maximum amount of content with a limited amount of losses.

The presence of a curved area and / or at least one corner in the sealing edge allows the packaging bag to fit well in the hand of the consumer. If the sealing lip were straight and connected the corresponding vertices of a triangular front surface and a triangular bottom surface in a straight line, the bag would be much more difficult to empty in the “extrusion format”. Without being tied to the theory, this is because the pressure applied by the consumer’s hand to the bag during the extrusion of its contents is at least partially applied to the back side of the bag. In the case of a bag in the “dipping format”, a straight seam connecting the tops could easily lead to a tipping bag in the direction of the front of the bag. But more importantly, the "dipping format" will be broken, since it will not be possible to form a proper bowl containing an acceptable amount of the contents of the bag and allowing you to dip the particles of the product or dip your finger in the packing bag. The contents of the bag will flow out of the bag on the table or into the hands of the consumer. Obviously, this is undesirable. A curved sealing edge or an edge containing an angle also provides a convex shape of the side surfaces, thereby increasing the packaging volume at least optically. As can be seen from the above, the packing bag does not have the shape of a tetrahedron or pyramid. Side surfaces preferably curved. This should be understood so that the side surfaces are not two-dimensional flat surfaces, but three-dimensional surfaces.

The bag according to the invention typically needs to be opened in order to allow the consumer access to the consumer product that wants to immerse the food component in the bag, or to allow the consumer to squeeze the contents out of the bag. The opening can be carried out, for example, by cutting off or tearing off the packaging bag. This is preferably carried out in the front upper part of the bag in order to create a small opening through which the contents of the bag can be extruded or poured. On the other hand, the consumer can cut or tear the top of the bag, preferably along the sealing edge. Thus, a "dipping format" is created. To facilitate the opening of the bag, there are preferably one or two on the sealing lip, most preferably two places (10) of the beginning of the tear. This place of tear usually has a notch, preferably a notch, passing through a part of the width of the sealing lip. In a preferred embodiment of the invention, the site of the beginning of the tear is located on the sealing edge, usually in its rear part, at a distance (d1) from the projection of the lower surface, which is from 50 to 100% of the length of the perpendicular line from the triangular front surface (see Fig. 7) . As shown in FIG. 7, the perpendicular line from the triangular front surface is the shortest distance from the top of the front surface to the support surface on which the bag stands. This line is usually perpendicular to the surface on which the bag stands, and therefore is called a perpendicular line. The person skilled in the art will understand that this is true for the case when the bag with its bottom surface faces the surface on which it stands. By breaking the bag, starting from this point of tearing, the upper part of the bag is removed in the direction of the front surface of the bag, as a result of which the bag is opened and its contents become accessible to the consumer. In this way, the "dipping format" is realized.

It may be preferable that the place of tearing is located in the upper part of the seal.

a dividing edge at a distance (d2) of 0.5 to 2.5 cm, preferably 1 to 2 cm from the front edge of the sealing edge. In a preferred embodiment of the invention, the tearing spot is located on the sealing edge, usually in its upper part, at a distance (d2) from the top of the front surface, which is convenient to measure along the outer edge of the sealing edge, which is from 10 to 30% of the distance determined by the projection of the top front surface on the projection of the lower surface and the top of the projection of the lower surface (see Fig. 8).

Most preferably, the bag according to the invention contains two sites for the start of tearing. They are preferably defined as the two sites of the beginning of the strain described above. After the start of the tear, there is preferably a line of weakness, especially after the start of the tear at the back of the sealing lip. The tearing point at the back of the sealing lip usually guides the break along the top of the sealing lip. It may be preferable to have lines of weakness after both sites of the beginning of the tear.

Preferably, the invention relates to a package in which one tearing point directs a gap that removes the top of the front surface, and is from the top of the front surface at a distance measured along the edge of the sealing edge of 10 to 30% of the distance determined by the projection of the top of the front surface onto the projection the lower surface and the top of the projection of the lower surface, and in which the second site of the beginning of the tear guides the gap along the upper part of the sealing edge, but it is preferably located at the rear of the sealing lip preferably at a distance from the projection of the lower surface of from 50 to 100% of the length of the perpendicular line from the front surface of the triangle.

Preferably, the line of weakness is made after at least one of the sites of the beginning of the tear, more preferably after all the points of the beginning of the tear. This may be a line of weakening, made by a laser. This loosening facilitates the removal of the part that must be removed to open the bag. In particular, if the area to be removed contains a curved part or includes areas with different texture or hardness, the rupture path may easily deviate from the intended course, as a result of which the contents may leak out of the bag during use or the dose will not be issued properly, or the bag will not be able to stand upright properly. Preferably, the bag contains two points of the beginning of the tear and at least one line of weakening, moreover, said at least one line of weakening is performed after the point of the beginning of the tear and guides the gap along the upper part of the sealing edge.

The packaging bag according to the invention is preferably used for portioning consumer products. As a consequence, the volume of the bag is not too large. In a preferred embodiment of the invention, the volume of the bag is from 15 to 40 ml, more preferably from 17 to 30 ml, most preferably from 17 to 25 ml. If it is too large, it is not practical to hold the bag in your hand for distribution or place it on a plate to dip food into it.

The material of the packaging bag is preferably flexible and not too rigid. This allows you to properly distribute the contents manually when an “extrusion format” is desired, while at the same time maintaining sufficient rigidity to stand upright autonomously when an “dipping format” is desired. It also allows you to remove part of the bag to open it by tearing it.

The material used for the packaging bag according to the invention may depend on the content of the bag. In principle, any closable, preferably heat sealable packaging material, such as a laminate, can be used. As is known to those skilled in the art, the thickness of the foil, the volume and contents of the packaging bag determine the choice of the desired material. A preferred material is an aluminum-polyethylene paper laminate.

The packaging bag according to the invention preferably contains a consumer product. The consumer product is preferably a liquid or paste. Preferably, it is an edible consumer product or personal care product intended for application to the body, for example, on the skin or on the scalp. More preferably, the bag according to the invention contains seasoning, sauce or personal care products. The personal care product can be a shower gel, shampoo or skin care product. Even more preferably, the bag contains mayonnaise, ketchup, mustard, soy sauce or curry sauce. Most preferably, the packaging bag contains mayonnaise or ketchup.

Another object of the invention is a method of applying a consumer product to a food product or body, includes the steps in which:

a) provide a bag according to the invention, and the packaging bag contains a consumer product,

b) open the packaging,

- 5 030678

c) enter the food product or finger into the contents of the bag or put the contents of the bag on the food product or on the body.

Preferably, step b) involves removing a portion of the sealing lip by cutting or peeling. Preferably, this step involves the removal of the top of the sealing lip or the front of the sealing lip, including the removal of the apical region of the front surface. Preferably, in this case, from 1 to 20% of the top surface of the front surface is removed. Stage b) usually includes tearing, starting from the place of the beginning of the tear, made in the form of a notch.

Step c) preferably involves squeezing the contents out of the sachet. Thus, the content is removed from the packaging bag. Alternatively, step c) may preferably include dipping the food product or dipping a finger into the contents of the bag.

Packaging bag can be made by a specialist in the field of packaging. It is preferably prepared starting from a single piece of foil, preferably a blank. Fabrication preferably includes folding, sealing and filling. Sealing preferably includes heat sealing.

Another object of the invention is the use of a packaging bag according to the invention for the distribution of a consumer product, for example, seasoning, sauce, shower gel, shampoo or skin care products. It may additionally relate to the use of a packaging bag according to the invention for offering to the sale of a consumer product, for example, seasoning, sauce, shower gel, shampoo or skin care products.
