Description

The invention relates to a container system for holding and metering liquid consumables such as cosmetic items. For this purpose, the container system consists of a main container, which can be connected to a pump device used to meter the consumables and can be combined with replacement containers made of material-saving, weight-optimizing and/or reprocessable materials, in particular renewable raw materials.

Cosmetic items offered on the market, such as soap, bath additives or shower gel, are predominantly stored in containers made of plastic or glass. In addition to the very attractive shape, these containers often also have a pump device that is used for dosing and can be easily operated by the consumer using a finger pressure. After use, these plastic containers, along with other plastic waste, also end up in the environment in a significant uncontrolled manner and represent an ever-increasing global problem.

Like in the DE 10 2008 030 076 A1 Among other things, beverage cartons represent an advantageous alternative to conventional containers made of plastic or glass. The beverage cartons, also known as composite packaging, are used for liquid or viscous filling goods. In particular, they serve as packaging for food, such as milk or fruit juice. Such packaging is on the market under the well-known name Tetra Pak. An opening with a cylindrical part protruding outwards is often made on the top of the packaging. On the surface of the cylindrical outwardly projecting part there is a thread which can be screwed to a closure which also has a thread. These packagings are suitable for “pouring” the contents. In contrast to containers made of plastic or glass, these packaging take up less space when folded. Due to their standardized size, these Tetra Pak containers are also easy to stack and therefore offer efficient logistical advantages. Furthermore, the empty packaging can advantageously be delivered to the filling plant in the form of a roll before filling. Established disposal companies ensure material recycling of the emptied packaging. The beverage cartons are currently also disposable packaging. However, the well-known Tetra Pak containers and stand-up pouches are the most ecologically sensible solutions. However, the main possible “pouring function” stands in the way of using these beverage cartons for cosmetic items.

It is known after the US 6,412,663 B1 a box holder for replaceable replacement containers made of semi-rigid materials such as cardboard that are inserted into the box holder. The box holder is used to prevent deformation of commercial boxes and its design offers the possibility of safe storage on a storage shelf, worktop or similar. The insertion takes place in the two opposite open sides of the box holder that have been recessed for this purpose and therefore provides attack surfaces for damage to the replacement containers. Furthermore, these open areas allow liquid substances to penetrate into the interior of the cardboard holder. This container system cannot be used as a waterproof container for use in shower cubicles, for example.

It is also known after the DE 600 34 190 T2 a tear-resistant bag that is used to hold a liquid or powdered cleaning agent or the like. The tear-resistant bag designed as a standing bottom bag is inserted into a container by squeezing the bag. The use of replacement containers with predominantly rigid or semi-rigid materials cannot be used in the main containers designed for this purpose. An advantageous replica of the main container as the original container for the liquid or powdered cleaning agents is also not provided.

With the US 2017 0 165 694 A1 A refillable container is described, which is formed from an outer container made of plastic, in which an inner container made of paper and containing liquids is inserted. A pump is arranged in the outer container and serves to pump up the liquid content in the inner container housed in the outer container and to pump the liquid content to an outside of the refillable container. The use of replaceable replacement containers of fixed shapes, such as in the form of a tetra pack container, is not provided for in the configuration of the container device. On the other hand, the inner container has material points that can be pressed in the middle of the upper surface, into which a tubular cylinder penetrates while the lid is closed. A sealing of the cover assembly and the connection points between the pump and the container against ingress of liquid substances from the outside is not provided for this container. There is also no advantageous replica of the liquid for the formation of this container The original container originally contained therein is provided.

The object of the invention is therefore to create a container system with exchangeable containers, which enables easy-to-use dosing of the liquid consumables and whose containers containing the liquid consumables are made from material-saving, weight-optimizing materials, in particular renewable raw materials, and / or after their use can be reprocessed.

This task is solved by the container system according to the invention according to the descriptive features of patent claim 1. Advantageous developments of the container system are described with the features of patent claims 2 to 9.

For the container system created, replaceable replacement containers are used to hold consumables such as cosmetic items, which are made from recyclable materials or other material-saving and/or weight-optimizing renewable raw materials. In contrast to conventional containers made of plastic or glass, these replacement containers represent an environmentally friendly alternative that also reduces costs in logistics and the production price. The containers, which are preferably made of cardboard, are advantageously connected to dosing pumps. This efficiently combines the advantages of easy operation when removing cosmetic items with an environmentally friendly and cost-effective design of the containers. In order to maintain the attractive design and color of the conventional containers for cosmetic items, the replaceable containers are alternatively accommodated in stationary receptacles. The containers serve as so-called refill packs. It proves to be beneficial if the conventional containers are separated into two parts that can be joined together in their traditional design. The upper part is connected to the dosing pump in a conventional manner. In a further embodiment, the lid is placed on the base container and the dosing pump is then screwed on. The replaceable container is placed in the interior of the assembled parts. When assembling the parts, the dosing pump is inserted into the opening of the container. Stand-up pouches or containers known under the name Tetra Pak are preferably used as commercial containers.

With the in 1 In the replacement container 2 shown schematically, a well-known Tetrapack container or stand-up pouch is used, which can be reprocessed or disposed of in an environmentally friendly manner after it has been emptied. The external visual design of the Tetrapack container in this variant is identical to that of the original container. In this way, the visually pleasing design of the original container is retained. The ones in the 2 Dosing pump 3 shown schematically is connected to the cover 7 in a physically fixed manner or can be screwed on. The 3 shows the assembled container system on a flat surface. The lid 7, which is made of solid material, is placed on the upper area of the Tetrapack container. With this measure, the pressure forces that occur when the metering pump 3 is actuated are distributed over the entire end face of the Tetrapack container. This avoids deformation of the Tetrapack container functioning as a replacement container 2. When the lid 7 is put on, the supply line becomes the metering device Pump 3 is pushed through the opening of the Tetrapack container into its interior.

At the one in the 4 In the main container 1 shown schematically, struts 9 are connected to form a frame structure which is used to hold the replacement container 2. As can be seen from the representation of the 5 As can be seen, the frame construction serving as the main container 1 together with the lid 7 forms a mechanically robust container system. This variant is particularly suitable for refill packs that have thin, easily bendable material walls. The thin-walled replacement container 2 inserted into the frame construction can, like the original container, withstand the pressure forces that occur when the metering pump 3 is actuated.

In the 6 the schematic structure of a receiving device 6 is shown, which is used to hold the main container 1. The receiving device 6 itself is for attachment to walls such as shower cubicle walls, sinks, etc. intended. The assembled container system with the wall-mounted receiving device 6 shows 7 . The main container 1, designed as a frame construction, with the replacement container 2 is inserted into the receiving device 6. The lid 7 with the connected metering pump 3 is placed on the upper part of the replacement container 2. The side surfaces of the replacement container 2, which are designed to resemble the original container, can be visually perceived through the open side surfaces of the frame construction.

With the 8th A variant of the container system according to the invention is shown, in which the main container 1 is designed to be closed. The respective replacement container 2 is inserted into the interior of the main container 1. The main container 1 consists of a base part 8 and a lid 7 that can be pushed onto the base part 8. The base part 8, the lid 7 and the metering pump 3 form a container that is waterproof to the outside when they are assembled. The bottom of the main container 1 consisting of the base part 8 and lid 7 is sealed watertight from the outside. When, for example, the container system is used in conjunction with a wall mount of a shower cubicle, the assembled container can also be removed from the receiving device 6 to remove the consumables.

In the 9 Dosing pump 3 shown is detachably connected to the lid 7 by means of the screw cap 11. However, a plug connection, a bayonet lock or similar types of connection can also be considered as detachable connecting means. In the embodiment shown, the metering pump 3 is designed as a spray device with an integrated lever system. The dosing pump 3, also commonly known as a cosmetic pump, has fixed strokes and therefore delivers fixed delivery quantities per stroke. And to increase the application range of the container system, the cosmetic pumps are designed to be adjustable. The desired stroke and thus the desired delivery rate are set using a mechanical lock or a variable adjustment wheel. The application would therefore be equally suitable for normal dishwashing liquids as well as for concentrated gaming liquids. Overdosing of consumables is thus avoided and this design counteracts waste of consumables. Furthermore, the cosmetic pumps can be equipped with a fill indicator for the replacement containers 2. Known float display devices are used for this purpose.

As in 10 reproduced, the surface of the main container 1 is designed so that it corresponds to the design appearance of the original container. There is therefore no need to place any special requirements on the design of the surface of the replacement container 2.

The schematic representation in the 11 shows the connection of the dosing pump 3 with a replacement container 2 designed as a stand-up pouch or TetraPack container. This type of connection can also be used to connect the dosing pump 3 to the lid 7. A screw cap with double thread 14 is used as the connecting assembly. The double threaded connection consists of an inner threaded connection 15 and an outer threaded connection 16. This variant of making the connection ensures a high degree of tightness.

The schematic illustration of the 12 shows the metering pump 3 with an adjustable telescopic tube 13. This embodiment enables the supply of consumables to otherwise difficult to access places. With the possibility of variable, continuous adjustment of the length of the telescopic tube 13, the range of applications is increased accordingly. The metering pump 3 is connected to the replacement container 2 or the lid 7 by means of the screw cap 11.
