Containers for liquid products

 

(57) Abstract:

Usage: as a package for storing flowable liquid products. The inventive packaging includes two placed one in another package. Inner package has a flap valve formed welded joints bent to the inside of the container upper parts of the walls of the package, between which is formed extending to the outside of the input channel. Flap valve has a narrow portion of a constant width, the length of which is equal to at least twice its width. A narrow portion of the valve is separated from the two sides from the rest of the design package rents. Tara has a straw that is located between packages. 6 Il.

The invention relates to packaging, and in particular to a container for storing a flowable liquid products, and may find application in the food industry.

Known containers for liquid products, made of thermoplastic film in the form of a flexible package having a receiving tube and flap valve [1]

The disadvantage of this design is its complexity caused by the presence of the receiving socket.

Known containers for liquids, made of thermoplastic films containing radar clap]

The disadvantage of this packaging is a bad leak, caused by the rigid connection of the output (input) channel valve with the whole design of the package, so when lateral compression of the container, the compressing force through the upper parts of the walls is transmitted to the input channel and he spontaneously opened, as the high pressure compression of the narrowest part of the entrance channel moves the liquid in the widest part where the pressure is less. Furthermore, the design of the package allows you to easily extract the contents through the valve, that does not preclude theft of the Packed product.

The purpose of the invention improve the integrity and reliability.

The objective is achieved by the fact that the packaging, containing a bag located inside the top flap valve comprising expanding outwards inlet valve, and a straw for drinking, further provided with a service located outside and having a height greater than the height of the existing package, the flap valve is directed to the inside portion of a constant width, the length of which is at least equal to twice its width, while the narrow part of the flap valve is separated from the rest of the structure rents, and the straw is located between vnutrennie; in Fig. 3 schematic illustration of the valve portion of the container of Fig. 4 section a-a in Fig. 3; Fig. 5 schematic representation of the valve parts containers (increased), deformed lateral compression in the location of slots; Fig. 6 is the same, the section a-a in Fig. 5.

Containers for liquid products includes the package, containing within it the upper part of the flap valve 2 and a straw 3 for drinking. Additional package 4 is located on the outside of the package 1 and has a height greater than the height inner pack 1.

Flap valve 2 is formed welded seams 5 of bent inside the container upper parts of the walls of the package 1 and is fixed in the upper part of its side seams 6, which are common to 4 external and 1 internal packages and valve 2. Flap valve 2 includes expanding outwards input channel 7 and directed into the container narrow part 8 of constant width "b", the length "l" equal to twice its width. In its widest part 7 input channel flap valve 2 made in one piece with the top of the package 1 or affixed to it. The narrow lower part 8 of the valve 2 is separated from the package 1 rents 9.

The straw 3 is located between packets 1 and 4 and serves to receive fluid through radar cleanedout brewing bottom seam 10 or through the top of the bag and the valve 2 with the subsequent brewing seam 11, it helps to achieve complete sealing of the packaging.

When using the container is opened by breaking out of the package 4 and the notch 12. The straw 3 is extracted from the space between packets 1 and 4 and is inserted into the flap valve 2 and through her by fluid intake.

Upon receiving the liquid and removing the straws 3 petals 13 of the valve 2 in its narrow 8 parts interlock and again seal the container, excluding the spilling of liquid through the valve.

The increasing tightness of the container is achieved by the features of the construct, flap valve, a narrow lower portion 8 which is separated from the package 1 by the slots 9 so that when the application's efforts "P" on the container, the width "B" it decreases, and the width "b" of the narrow part of the valve 8 remains constant and is not deformed. Therefore, the stronger the pressure on the container, the more closed the petals of the valve 13 2.

In order to make it possible to re-extract the liquid from the container, insert a straw 3 in the input channel flap valve 2.

It is obvious that the present invention proposed a new efficient design of packaging suitable for filling fluid liquid product, such as juice, beer is minki from the inlet flap valve.

Industrial production of packaging, the proposed design is planned for JSC "Crystal", Kaluga.

Containers for liquid products containing package having located inside the upper part of the flap valve, which is formed extending to the outside of the input channel, and a straw for drinking, characterized in that the container is provided with an additional package having a height greater than the height of the existing package, and located outside the latter, flap valve is directed inside the narrow part of the constant width, the length of which is equal to at least twice its width, while the narrow part of the flap valve is separated from the two sides from the rest of the designs is available package rents, and the straw is located between the inner and outer packages.

FIELD: food industry; packing of food slices.

SUBSTANCE: food slice consists of two or more products, for instance, nut paste and jelly. Proposed method provides simultaneous and separate transfer of each of two or more products to place of extrusion, control of water activity of two or more products either before and after separate transfer of products, simultaneous and separate extrusion of each of food products and injection of food products into tubular film web which is sealed in longitudinal direction. Food products are combined into preset portion of food using method of portion control which changes speed of extrusion basing on amount of available portion of food product. Food products inside packed portion preserve their identity. Then portion of food products is sealed inside flexible film. Invention provides slice in form of cohesion mass containing two or more different food products with possibility of simultaneous complete release of food products from wrap by hand which is sufficient for holding, handling, eating or using food products in other places as need be.

SUBSTANCE: invention relates to the field of manufacturing package for preserved food and is aimed to prevention of customer misinformation on package contents. The method stipulates can labeling with labels made of composite material with temperature resistance that is higher than sterilisation temperature, with label placement on can surface including seaming zone, filling cans with product, can sealing and sterilisation.

EFFECT: when a label is removed cutting tool leaves a trace on can surface and label material comes out of seam; this prevents traceless replacement of labels on cans and excludes customer misinformation on can contents.
