Description

The invention relates to an output device for liquid media in a container and a seal for such containers for positioning in the output device.

In the catering trade as well as in private households, it is advantageous for cost savings if larger containers, for example, with contained therein olive oil, bought and then, if necessary, the olive oil is removed from such containers. Usually, five liter containers are sold, for example, with olive oil. However, in order to allow easy dispensing of the liquid medium from such large containers, these five-liter containers are transferred to half-liter or one-liter units to be subsequently filled with these small containers to work. This is disadvantageous especially in the catering industry, since an additional expenditure of time is required to fill such large containers into small-volume units.

The invention has for its object to provide an output device for stored in containers liquid media, which allows a simple and metered output of the medium from the container and a simple insertion and removal of the container in and out of the output device. Furthermore, the invention has for its object to provide a seal for such a container, which is insertable into the output device.

The object for the metered dispensing of liquid media in a container as required is achieved in that the dispensing device has a container receiving space in which the container can be used and fixed in a simple manner. In this case, the container is fed in the insertion direction of the container receiving space, wherein a bearing surface of the bottom of the dispensing device and at least two opposing side walls are each arranged with a lower retaining edge to the support surface of the bottom of the dispenser, that the outer peripheral edge of the container lid between the support surface of the bottom and at least partially guided and positioned in the lower retaining edge of the side walls. As a result, the dispensing device on the one hand can be designed very simply and, on the other hand, a secure positioning of the container by the fixation on the peripheral edge of the container lid can be made possible. Furthermore, there is the advantage that, for example, two and a half, three, four, five or six-liter containers, which have the same container lid base and the same peripheral edge on the container lid, can be used, so that in this output device also different sizes Containers are used and usable. Via an outlet which can be arranged on the container lid, the liquid can be dispensed downwards, for example, via a hose and a clamping valve or the like arranged thereon.

A preferred embodiment of the dispensing device provides that the retaining edge of the side wall is adjacent within or on an outer edge of the support surface and positioned at a distance above the support surface of the bottom, wherein the distance corresponds to the thickness of the edge of the container lid. The retaining edge is preferably formed by a narrow end face, which is determined by the wall thickness of the side wall. In this case, the lower retaining edge of the side wall and the bearing surface of the bottom at least partially and / or partially congruent to each other. Likewise, the support surface and / or the lower retaining edge of the side wall may each be formed in sections, and the respective sections may always be offset relative to one another in a gap.

A further preferred embodiment of the invention provides that at the bottom forming the support surface each side a fastening tab is arranged, which carry the opposite side walls. For example, this output device can be formed in a simple manner as a sheet-metal stamped part, wherein the bottom and the fastening tabs form a component and the side walls form a separate component. By a folded edge of the attachment tabs on the bottom, the side walls can be supported, whereby on the one hand a simple and constructive design and positioning of the side walls to the support surface and on the other hand lateral guidance of the edge are made possible on the container lid.

A further preferred embodiment of the dispensing device provides a third side wall as a rear wall, the lower retaining edge or support surface facing the support surface attacks at least in sections above the edge of the container lid of the container inserted into the receiving space. As a result, the edge of the container lid is at least partially encompassed on three sides of the container and thus enables improved fixation of the container.

The third side wall is preferably formed integrally with the other two opposite side walls. Thus, in the training as a sheet metal bending stamped part by a simple Umbantung be given a U-shaped encirclement of the container. Preferably, the third side wall is provided or formed for attachment to a wall or a device. For this purpose, fastening openings may be provided for the introduction of fastening means or as suspension openings or the like.

A further preferred embodiment of the invention provides on the container bottom a recessed support surface for an insertable outlet, which consists of an outlet pipe with a Aufstechdorn and a holding plate. This outlet is mounted prior to insertion of the container into the dispensing device on a container lid, wherein a piercing spike a seal in the container lid is pierced, so that the outlet pipe projects with a portion in the container and with the other portion free to the outside. Subsequently, the container is transferred with the outlet used in an overhead position and inserted into the container receiving space of the output device. By the recessed support, whose recess preferably corresponds to the thickness of the retaining plate of the outlet, the outlet is also positioned and held in the correct position in cooperation with the container lid in an inserted position in the dispensing device.

A further preferred embodiment of the dispensing device provides in the recessed support a U-shaped recess, which is open in the insertion direction of the container. This U-shaped recess allows for easy insertion of the outlet from the front, so that the free downwardly projecting portion of the outlet pipe can escape via this recess down.

The seal preferably has a central opening with a smallest diameter, which is formed by a circumferential bead. As a result, after the insertion of the outlet pipe into the central opening, an annular seal can be formed to the outlet pipe, whereby a permanent tightness during the overhead arrangement of the container for the portioned dispensing of the liquid medium is ensured. Preferably, the smallest diameter of the central opening is smaller as the outer diameter of the spout. As a result, the circumferential bead is under low bias on the outer circumference of the spout.

Furthermore, the sealing body preferably has a peripheral shoulder on the outer circumference and, adjacent thereto, to form a groove-shaped depression, a peripheral latching nose with preferably an insertion bevel. This arrangement allows the seal to be easily plugged onto an outlet opening in the container lid. This is supported in particular by the insertion bevel. By forming the circumferential locking lug, a simple snap-in and fixation of the seal in the container opening or outlet opening can be ensured.

Furthermore, it is preferably provided that the sealing body has on an inner end face an annular collar delimiting the inner end face, which has at least one recess whose depth preferably extends to or close to the inner end face. This makes it possible for the liquid medium still remaining on the container bottom to collect in this receiving space and also to be dispensed, for example, via the transverse bore in the outlet pipe. This can increase the degree of emptying.

Furthermore, the sealing body is preferably formed of an acid-resistant or plasticizer-free or food-resistant or vegetable oil-resistant plastic. Depending on the stored liquid media, the plastic material can be selected accordingly.
