RU187473U1 - Tea Packaging - Google Patents

Abstract

The utility model relates to disposable containers for immersion in a liquid with contents that are brewed, infused or dissolved in place. The technical result of the proposed utility model is to reduce the likelihood of the product pouring out for brewing through openings. The packaging is used to store and brew brewing products. During use, the packaging is dipped in a glass of water. Water enters the cavity 7 through openings 5. Next, extraction or dissolution of the brewing product takes place with the passage of the corresponding components into water or another liquid. Due to the fact that the holes 5 on the side of the cavity 7 in which the brewing product 6 is placed have a protrusion 11 , the probability of pouring out the product for brewing 6 is reduced. Moreover, the protrusions 11 completely prevent the pouring out of the brewing product 6 when it is stored in the package or limit the intensity of this process due to the retention of the product particles closest to the hole 5 KTA infuser 6 itself from falling into the hole 5. In the case of chipping particles of product for welding are fixed in a fixed position and can not leave the package.

Description

Technical field

The utility model relates to disposable containers for immersion in a liquid with contents that are brewed, infused or dissolved in place.

State of the art

The closest technical solution (prototype) is the packaging of products for tea leaves (RF patent for utility model 158129, published on December 20, 2015). The packaging of the brewing products is made in the form of a water-permeable container, inside which a portion of the brewing product is located. The container is formed by a perforated tube of a three-layer material, the ends of which are sealed by heat sealing. The three-layer material includes two layers made of heat-sealable biaxially oriented polypropylene film with a thickness of 20-48 μm, and a layer located between the layers made of aluminum foil with a thickness of 2-12 μm, the tube height being 100-160 mm and the maximum cross-sectional size the tube is 17.5 mm. The holes in the tank provide the flow of water and the output of the brewing product out.

A disadvantage of the known technical solution is the partial precipitation of the product for welding from this package. The size of the holes allows the particles of the brewed product to fall into the corresponding hole and fall out of the packaging.

The technical result of the proposed utility model is to reduce the likelihood of rash of the product for welding through holes.

The specified technical result is achieved due to the fact that in the packaging of products for welding, made in the form of a tube formed by the wall, the tube having a first end and a second end made closed, a cavity is located inside the tube and holes are made in the wall connecting the cavity with the environment , in the cavity there is a portion of the product for welding, from the cavity side around each hole there is a protrusion surrounding the corresponding hole and provided with an edge from the cavity side, the tube is made and three-layer material including a layer of aluminum, in the particular case of the edge is smooth, in another particular embodiment, the edge is formed with notches.

Brief Description of the Drawings

The utility model is illustrated by a drawing (Figs. 1-5), where Fig. 1 is a front view, Fig. 2 is a section A-A, Fig. 3 is a sectional view of a hole with a smooth edge, and Fig. 4 shows a section through a hole with a serrated edge; FIG. 5 is a rear view.

Utility Model Disclosure

The drawing shows: the first end 1, the shell 2, the second end 3, the transverse seam 4, the hole 5, the welding product 6, the cavity 7, the outer layer 8, the intermediate layer 9, the inner layer 10, the protrusion 11, the edge 12, the inner surface 13, longitudinal seam 14.

The packaging of brewing products is a packaging or container for storing the brewing mixture, or brewing products, as well as a packaging or device with which and partially in which brewing of these products occurs when the packaging is immersed in a container with liquid and the specified liquid circulates between the cavity 7 in the package and the total volume of liquid in the container through the holes 5.

The packaging of the brewing products (hereinafter, for brevity, also the packaging) is made in the form of a shell 2. Shell 2 - a solid deformable body limited by two curved surfaces, the distance between which is small compared to two other sizes (Internet resource: https: / /dic.academic.ru/dic.nsf/enc_physics/ 1782 / SHELL, accessed 02.11.2018). In this case, the shell 2 is formed in the form of a tube with a first end 1 and a second end 3. The tube is formed by a wall. The tube section, in a particular case, has an oval shape. The wall surface facing the center of the tube is the inner surface 13. The first end 1 of the tube and the second end 3 of the tube are closed, i.e. muffled by connecting the inner surface 13, with the formation of the corresponding transverse seam 4, located perpendicular to the length or the imaginary axis of the tube. Thus, a cavity 7 is formed inside the tube.

The wall is made of a three-layer material. The three-layer material includes an outer layer 8 and an inner layer 10 made of biaxially oriented polypropylene film, and an intermediate layer 9 located between the above layers and made of aluminum foil (the use of this type of film is widely known - see, for example, the RF patent for useful Model 158129, European Patent Application EP 1 946 652 A1).

Holes are made in the wall 5. Holes 5 are made connecting the cavity 7 with the environment. The holes 5 are arranged in rows located in the direction of the length of the tube. Shell 2 can be divided into three areas. Of these, openings 5 contain only two regions. The region without holes 5 is located on the side of the first end 1. The two remaining regions differ from each other in that the number of rows in one of the regions is greater than the number of rows in the other region and the distance between the rows is less. An area with a large number of rows is located on the side of the second end 3. An area with fewer holes 5 is located between the aforementioned area and the area without holes 5. In a particular case, in the area with fewer holes 5, the distance between the nearest holes 5 in the same row is the distance between in rows. The corresponding holes 5 in the adjacent rows of this region are located at the same distance from the second end 3. The holes 5 of each row of the region located on the side of the second end 3 are offset from the holes 5 of the adjacent row.

There is a ledge 11 around each hole 5. The ledge 11 is a local elevation above the smooth surface of the body of the structure (Internet resource: https://dic.academic.ru/dic.nsf/stroitel/1425, accessed 11/16/2018). The protrusion 11 is located on the side of the cavity 7 around each hole 5, i.e. along its perimeter. The protrusion 11 on the opposite side from the inner surface 13 ends with an edge 12. In the first particular case, the edge 12 is smooth. In the second particular case, the edge 12 is provided with notches.

A portion of the brewing product 6 is located in the cavity 7 (in figure 2, for simplicity, one particle of the indicated product is conventionally shown, it should be understood that much more is located in their cavity).

Utility Model Implementation

In the case of using the above elements and means, the utility model is implemented as follows (the presented description of the object illustrates a particular case of its execution, other implementations using the features of this technical solution are possible).

A long tape is preliminarily made of three layers: a biaxially oriented polypropylene film, aluminum foil and a biaxially oriented polypropylene film, connected in series to each other in the indicated order. Then, holes are made in the three-layer material using needles 5. The location of the holes 5 is set in accordance with the above-described order of their location in each part of the sheath 7. The opposite edges of the tape (or blanks cut from it) are overlapped to form a longitudinal seam 14. As a result get the shell 7 in the form of a tube with a first end 1 and a second end 3. The first end 1 and the second end 3 are compressed in the direction perpendicular to the axis of the tube and closed or connected due to thermal or ultrasonic action. As a result, transverse seams 4 are formed, perpendicular to the longitudinal seam 14 and located respectively from the side of the first end 1 and the second end 3.

The protrusions 11 around the holes 5 on the inner surface 13 of the shell 7 are formed, for example, by piercing with heated needles, which leads to the formation of an “influx” of material around the perimeter of the hole 5 and the formation on the inner surface 13 of the perimeter of the holes 5 of the protrusions 11 with a smooth edge 12, or as a result of quick piercing with cold needles, which leads to tearing of the material around the perimeter of the hole 5 and the formation on the inner surface 13 of the perimeter of the holes 5 of the protrusions 11 with a serrated edge 12.

Before forming the last of the transverse seams 4, a portion of the brewing product 6 is poured into the cavity 7, for example, tea, instant coffee, other powdered or similar materials.

Packaging is used for storing and brewing brewing products. During use, the packaging is dipped in a glass of water. Water enters the cavity 7 through openings 5. Next, extraction or dissolution of the brewing product takes place with the passage of the corresponding components into water or another liquid.

Due to the fact that the openings 5 on the side of the cavity 7, where the brewing product 6 is placed, have a protrusion 11, the probability of pouring out the brewing product 6 is reduced. Moreover, the protrusions 11 prevent the brewing product 6 from spilling out completely when stored in the package or limit it the intensity of this process due to the retention of the particles of the brewing product nearest to the hole 5 from getting into the hole 5. In the case of nicks, the particles of the brewing product are fixed by them in a fixed position and cannot leave the package.

Thus, the implementation of the device in the manner described above reduces the likelihood of a rash of the product for welding 6 through the holes 5 during storage or during use.
