Description

The technical solution relates to devices for opening cardboard packages and extracting liquid products (fruit juice, milk, etc.) from them by punching the top wall of the package.

Known mounted in one of the walls of the packaging device for opening cardboard packaging by removing (unscrewing) the cover of the release (for example, a device [6] by Tetra Laval, combined packaging [7], a plastic shutter and cork by Berikap GMBH [8] as well as by opening (folding) a special hinged valve cover (for example, a device [4] of the Swiss company Tetra Laval Holdings ", packaging with a hinged lid of the German company" Foke und Co. "[9]. Such devices require a special design with a single of hermetic factory casting of the wall with the release, which complicates the production and increases the cost of the packaged product.

Existing packages with lashing ears (for example [5] from Isikatron, UK) that allow opening the package by tearing part of the walls, which facilitates manual tearing of the package, but also requires special production.

For packages that do not have devices for opening them associated with them, devices have become widespread (for example, [2, 3, 10])

opening cardboard packages by punching a wall (for example, punching a specially designed hole with a weakened membrane for small containers with juices with a tube) or by squeezing a drain hole at the wall with weakened perforation [3, 4].

To open packages with wines, combined packages are used (for example [3]), which have a built-in outlet valve-valve on the inner polyethylene container and are designed to extrude perforation on the outer cardboard package.

However, the known device for opening packages with manual punching by cutting off their ends or forcing perforations is inconvenient to use for mass use (in bars, cafes, etc. establishments), and packages with special devices (screw caps, stoppers, opening closures, etc. .) are relatively expensive and are not intended for mass use.

A device [2] for extracting liquid from a package contains a chamber with a neck in which a pointed nozzle for piercing a container is installed. The device [2] relates to paired (built-in) packaging devices for opening it.

The disadvantage of the device [2], as well as other analogues, is the need for special production for casting a sealed packaging blank along with the release (screw cap or valve cover). The device [2], taking into account the one-time use of packages, is not rational and economical enough for mass use in public catering facilities with an unjustified increase in the cost of the product removed from the package.

The known nozzle [1] for opening a cardboard package and extracting liquid products from it, adopted as a prototype, relates

to devices for opening packages that are not equipped with units for opening them associated with them (integrated in packages).

The nozzle [1] contains a body and a cover for discharging the contents of the package, the body includes a drain chamber, pointed pins for punching the upper rectangular base of the package, connected to the drain chamber, a cover for release is installed in the upper part of the drain chamber and made relatively movable, the pins for The punchings have internal channels for draining the liquid from the package into the drain chamber through the outlet openings and are made in the form of knife pointed hollow rods.

At the same time, the nozzle body [1] is equipped with guide plates (in the form of corners) for installing the nozzle diagonally on the upper rectangular base and drain chamber stops made of strictly defined sizes.

Thus, the nozzle [1] is intended only for opening rectangular packages of strictly defined dimensions (for example, only with a capacity of 1 l) and cannot be used for opening packages of other sizes and shapes other than rectangular (for example, cylindrical), i.e. the nozzle [1] is not universal.

The essence of the proposed utility model is to create a universal nozzle for opening cardboard packaging having various sizes and shapes.

The main technical result of the proposed technical solution is the expansion, unlike the prototype [1], of the functional purpose and capabilities by implementing a universal nozzle that provides the possibility of opening cardboard packages of any size (or one package from different sides), as well as the possibility of opening packages with a different rectangular shape (for example, cylindrical, in the form of a tetrahedron, etc.). Also worth

the proposed nozzle in comparison with the device [1] is to simplify the design (the absence of guide plates, limiters of the drain chamber) and, as a result, increase operational reliability.

The technical result is achieved as follows.

A universal nozzle for opening a cardboard package and extracting liquid products from it contains a housing and a cover for discharging the contents of the package, the housing includes a discharge chamber, pointed pins for punching the top base of the package connected to the discharge chamber, the release cover is installed in the upper part of the discharge chamber and is made relative to her moving. Moreover, the punching pins have internal channels for draining the liquid from the package into the drain chamber through the outlet openings and are made in the form of knife pointed hollow rods.

A distinctive feature of the nozzle is that the drain chamber is made of two sections, each of which is equipped with a piercing pin at the bottom, and has a shoulder in the upper part, the lid is movable relative to the sections of the drain chamber by means of a recess for interacting with the shoulders of these sections. In this case, the sections of the drain chamber and the ends of the lid are rounded outwardly.

In addition, the upper surface of the lid may be provided with a transverse notch.

Figure 1 shows the General structural diagram of the nozzle for opening the cardboard packaging and extracting liquid products from it (top view and side view), figure 2 presents a view along section AA.

The nozzle contains a housing 1, a cover 2 with recesses 3, sections 4 of the drain chamber with flanges 5 and pointed pins 6, in which internal channels 7 are made with outlet openings

8. Number 9 indicates the base of the package pierced by the pins of the nozzle.

The opening of the cardboard packaging and the extraction of liquid products from it through the proposed nozzle is as follows.

The cover 2 of the nozzle made of plastic, with recesses 3, is mounted (latched) onto the shoulders of 5 sections 4 of the chamber drain chamber 1. By moving sections 4 along the cover 2 (shoulders 5 move in the recesses 3 of cover 2), the distance between the pointed pins 6 is set in accordance with the dimensions punched base 9 packaging. The nozzle thus assembled from the housing 1 and the cover 2 is ready for operation and is mounted on the packaging base 9 in the place of least resistance (outside the sealing area of the base 9, formed, for example, by bending and / or fastening the packaging). In this case, the pins 6 are placed perpendicular to the base 9. By pressing (or lightly impacting) the palm of the cover 2, the nozzle moves down to the stop of the sections 4 of the drain chamber into the base 9. In this case, the pins 6 pierce the base 9 of the package, and when it is tilted, the liquid flows through the internal channels 7 pins 6 through the outlet 8 enters the drain chamber. The movement of the cover 2 for the release of fluid is provided by the action of a finger (or palm) on the cover 2, on the upper surface of which, for greater efficiency of the interaction of the hand with the cover 2, a transverse notch can be applied. The optimal flow of liquid discharged along the rounded end of the section 4 of the liquid discharge chamber is controlled by moving the cover 2 relative to sections 4 along the shoulders 5. If there is no need to discharge liquid from the package (when storing the package that has already been opened), the cover 2 moves to a position in which sections 4 are completely closed from above.

Thus, a special constructive implementation implements a universal nozzle for opening cardboard packages having various sizes (for example, packages with a capacity of 0.5; 1; 2 l) and shape, thereby expanding functionality, as well as increasing operational reliability by simplifying the design by compared with the prototype [1].
