"Closed container"

The invention relates to a closed container, the egg »e has a hygienically clean peripheral lip or edge area when the cap is removed for drinking or serving,

Containers that form a hygienically clean drinking lip, simd known. Often in such containers, the closure and

the outer, downward part of the land is sealed, for example by welding plastics to the container either by welding the downward one Edge of the wall of the container or by welding the lid to the upper edge of the container wall. In such Containers are also used plastic closures or plastic lids made of film, which have a downward-facing Have edge portion that is welded to the wall of the container. In these containers, the welded joint is in one Tear-open design provided so that when the edge portion is lifted, the welded connection is released to the closure to remove and expose the hygienically clean edge of the container. Other containers have a plastic cover provided for the edge of the container wall, in which an inner lid section is provided, with a removal of the lid section and then a removal of the plastic edge covering is required.

According to the invention, the drinking rim of the container is hygienic in one kept in a clean condition during shipping and storage or installation by a Layer that can be sprayed on or applied in any other way before closing takes place »A lid or a closure, preferably made of flexible plastic film, is applied to the top portion of the coating on top of the lip of the container adhered to seal the filled container.

The cover sheet may have a shape in which one or more Corner parts arise that protrude beyond the container to serve as a handle, with the help of which the closure of the container can be removed.

The invention aims to provide a container of the aforesaid Type in which the coating of the container lip is in the form of a strippable pad attached to the closure adheres so that a decrease in the closure leads to a simultaneous stripping of the coating to one Expose hygienic clean lip around the end of the container.

The invention also provides for the creation of a container of the type mentioned, in which the closure part with periphery Extensions are provided beyond the coated lip, which can serve as handles, with the help of which the lid and the coating film can be removed from the container.

The invention also provides for the creation of a container of the type mentioned which has an outwardly beaded drinking rim whose exposed part under the lid is completely covered with the strippable coating during transport and storage is covered.

The invention also aims to provide a container,

which is suitable for an inexpensive production with a simple coating for the drinking rim of the container and one alike simple adhesion of the lid to the applied hand coating is suitable for sealing the contents of the container.

The invention is described below on the basis of an exemplary embodiment explained in more detail with reference to the drawings. In the drawings are:

Fig. 1 is a diagram of the sealed container;

Figure 2 is a detail in half section showing the sealed container;

3 shows a detail in section showing the beaded edge of the container to which the strippable Coating has been applied before the closure has been applied;

FIG. 4 shows a representation similar to FIG. 3, but in which the closure is fitted, and

Figure 5 is a diagram showing the partial removal of the closure and strippable coating from the container shows.

The container has a wall 10 of round shape which tapers downwards and inwards towards the closed bottom. The top of the Wall 10 is provided with an outwardly, downwardly and inwardly curled peripheral lip 12 which is initially coated will be used to maintain their hygienically clean condition, as will be pointed out. A non-round foil lid or closure 14 made of suitable film material is by adhesion, by heat sealing or the like. on the coated Lip attached. The shutter 14 is provided as shown in a square or rectangular shape, so that its corner parts 14a, b, c, d protrude beyond the lip and form handles that are lifted up and over the open The end of the container can be brought to open it so that you can get to the contents, what to point out will be.

As shown in FIGS. 2 to 4, the upper one is peripheral The edge portion of the wall 10 is crimped outwards, downwards and inwards to form a crimped lip 12. A thin one Coating 16 is applied to the outer surface of lip 12. This coating extends from the inner edge 16a around the remaining area of the lip up to the free, inwardly directed edge 12a. After the container is filled, will the closure made of plastic film is put on and covered with the coating film 12 sealed or welded, as shown in Figure 3 at 18, so as to seal the contents of the container. From the sealed area 18 to the edge 12a of the lip

the coating film 16 protects the underlying lip surface from contamination, and when it is removed, the exposed surface is in a hygienically clean one Condition for lip contact so that one can drink from the container or otherwise remove the contents of the container can. The removal of the closure 14 and the coating layer 16 is in Pig. 5 shown where that flexibility can be seen the closure film facilitates its rolling back in order to allow the coating layer 16 to be stripped off the container lip 12 support so that the hygienically clean surface of the container lip is exposed for drinking or for other distribution of the contents of the container.

The material of the closure 14 and the coating layer 16 are made of a suitable plastic, for example polyethylene-based materials, and the container can be made of Plastic, paper or another suitable material. The coating material can be applied to the container lip be applied in any suitable manner, for example by spraying, by curtain coating and the like The coating layer is relatively thin in order to facilitate its removal from the container lip when the closure is removed. When stripping from the container lip, the insulation layer for this purpose extend or tear », depending on the material used; but it essentially consists No area liability between the coating layer and the

Area of the container lip resulting from the coating. Me closure film 14 can with the upper surface portion of the Coating layer 16 may be connected in any suitable manner, for example by adhesion, in the case of plastics it is but more expedient to make a connection therebetween by means of heat and pressure, whereby the sealing area 18 according to FIG the illustration in Fig. 4 is flattened somewhat. The seal at 18 between the closure and the coating layer is sufficiently tough to hold together for the purpose of stripping off the coating layer when the closure is removed to maintain even if a certain adhesion between the coating layer and the container lip in the area 18 than The result of heat sealing can occur if the container material is made of an appropriate plastic.
