DE102013002004A1 - Container assembly for storing and dispensing carbonated drink in beverage industry, has outer container and inner container which is equipped with dispensing device for holding, storage and controlled dispensing of liquid - Google Patents

Abstract

The container assembly has an outer container and a fixed, flexible, compressible or collapsible inner container. The inner container is equipped with an integrated or separate dispensing device, for holding, storage and controlled dispensing of liquid e.g. carbon-dioxide liquid. The outer container is made of plastic, corrugated cardboard, metal, glass, or timber. The inner container is made of metal or plastic such as polyethylene and polyethylene terephthalate.

Description

The invention, the CO2 liquid packaging, extends previous liquid packaging systems based on the principle of an outer shell and a second inner, liquid / gas-tight container, possibly with a filling / removal option in addition to the ability to absorb CO2-containing liquids to store and remove.

This type of containers is called in the art, for example, bag in box, if a flexible bag is used as inner container. The outer container is predominantly made of solid cardboard or corrugated cardboard. So far, this container combination can only be used meaningfully with CO2-free filling material.

Conventional containers for CO2-containing beverages are so far glass bottles, plastic bottles, barrels made of plastics or metals and plastic pressure vessels containing an inner container made of plastic films, in different sizes with different possibilities of liquid extraction. These are, if not just intended for direct pouring, taps or dispensers.

However, the principle of the outer protective cover and the contents carrying inner container is very useful for many economic, practical and environmentally friendly aspects.

In order to be able to use these advantages in the future for CO2-containing liquids, a way has to be found to change the "weak" system so as to handle the resulting internal pressure by filling CO2-containing products such that neither these themselves, nor the contents or storage life be adversely affected.

This now solves the invention, the CO2 liquid packaging, now either by using an intended pressure-resistant container as an inner container, the outer container is thus reinforced to withstand the load or a combination of these two solutions.

The following descriptions contain references to the sketch section starting on page 8.

According to the invention, an apparatus is now claimed which in its basic form can consist of a dimensionally stable outer container made of a suitable material, a solid, flexible, compressible or foldable inner container, for example a bag or a bottle, with a removal option, such as a tap.

The outer container is designed so that the removal of the inner bag, can be performed from the inside out to get to the contents. This breakthrough or weak point may be formed on the outer container so that it is not visible before use, or not at first glance, from the outside, for example, a perforation. In this case, the weak point can be formed so that the use of the whole unit, the weak point is pressed to get to the tap of the inner container. This breakthrough can be advantageously designed with the removal possibility of the inner container that they fit together and / or engage in order to be able to be brought into the intended position.

If, instead of a beverage bag which coincides with the removal of liquid, a more dimensionally stable material such as standard (PE / PET) bottles or metal is used as the inner container, the outer container does not serve as a pressure body. This task then has The inner container.

Particularly advantageous here is that now in particular "ordinary" 3 and 5 liter PE / PET bottles can be used industrially for carbonated drinks, which previously reserved only drinks with screw cap or were not filled at all in these container sizes, combined with the special added benefit one " Even Zapf Party Fasses ".

The sketches 1 and the following describe the principle and various characteristics by way of example

1 , and the following, refer specifically to the drawings with the examples shown in perspective. The numbers in brackets () refer to similar parts in all sketches. The sketches describe the principle as an example of a beverage container for beer.

1 (a) Outer container - (b) Inner container, here as a beverage tube / bag, with the possibility of withdrawal: Tap (c).

Here, the pressure body (a) one or more layers of particularly structurally strong corrugated and / or honeycomb cardboard is made. When using a cylindrical shape pay particular attention to the durability of the connections between the bottom and the lid.

The forces arising in (b) are absorbed by the sufficiently strong construction of (a). Thus, the internal pressure in (b) is physically guided by the force conservation set without self-loading of the sheath of (b) into the sheath (a). (c) is a so far optimized variant of a bag in box tap, in order to counteract the pressure conditions, up to 3 bar, and reduce the foaming tendency when tapping foam-forming liquids.

In the case of a professional bottling, (b) is filled in the usual way, like ordinary beverage bags, at the suitable bottling plants. The product must be cooled down to a temperature close to 0 ° Celsius at which the CO2 dissolved in the liquid does not bubble out in the product. In the second step, (g) is attached in the next process and packaged directly in (a). It is important to keep this relatively timely, so that the contents are not heated by the change of state of aggregation and the bag is pressurized before it is spent in the pressure vessel (a). After closure of (a) the container is ready to use.

2 (a) outer container made of printed or offset-laminated corrugated cardboard, designed as a decorative cover and transport protection but not for pressure absorption (b) inner container, here as a standard PET bottle which is sufficiently designed for filling with CO2-containing liquids, with the possibility of removal: dispensing system (g).

(g) is a combined component, which is connected to a matching to PET bottle lid screw cap (i) to (b), via the conduit (f) with the tap (c). The system is designed to counteract the pressure conditions, up to 3 bar, and reduce foaming tendency when scooping foam-forming liquids. It can through 3 be supplemented. In a professional beverage bottling (b) is filled in the usual way, such as ordinary PET bottles or 5 L metal party beer kegs at the appropriate bottling plants, in the second step in the next process (g) and the container is cleaned and possibly dried. In the final step, the filled unit is then packaged in (a) and ready for use.

3 Dispensing system (g)
Modular filling and pressure compensation system (d) and / or (e) connection option for external CO2 supply (h)
