    Container having an injection moulded lid with drain holes covered bv a peelable cover element
    The current invention relates to a container comprising a container body and a lid mountable on said container body, said container body comprising a bottom, side walls and an opening delimited by a rim portion and said lid comprising an injection moulded rim portion which is arranged to be mountable on the rim portion of the container body in a manner which allows the lid to be detached from the container body and then later re-attached on the container body and a central lid portion which is fastened to the rim portion of the lid and which covers the opening of the container body when the lid is mounted on the container body.
    Some food products are stored in a liquid to preserve the food product during storage. Some examples of this are pickled herring, picked onions, pickles, olives in oil, feta cheese in salt water, etc... When accessing these food products, it is always troublesome to get the food product out of the liquid.
    Typically, the user is forced to dip into the liquid with a fork or other utensil and fish the food product out of the liquid. Or, the user opens the lid partially and attempts to pour the liquid out of the container via the half open lid. In this case, depending on the user's skill and luck, there is a risk that food products escape out together with the liquid or that the liquid ends up all over the place or some of the liquid remains in the container.
    Furthermore, some products are stored dry, but then liquid is added and then removed again prior to eating. Some examples of these types of products are rice which needs to be cooked, noodles which need to be cooked, etc... In these cases, the liquid can be very hot, whereby it is required that the liquid can be removed in a simple manner without risking that the user gets scalded by the hot liquid.
    Description of related art
    Different solutions have been proposed to this problem in the prior art. One solution to this problem is to place a sieve element in the container underneath the lid. When the lid is opened, the user can lift the sieve element out of the container with the food product being captured in the sieve. The liquid can then be poured out of the container. An example of this type of product is shown in W014085934.
    Another solution is to provide a two ply foil lid welded onto the container where a portion of the foil is peelable to expose openings in a lower layer of the foil. The liquid can be poured out through the openings of the lid and once all the liquid is removed, the foil lid can be completely peeled off the container body. An example of this type of container is shown in EP1162156. Another similar container in the form of a metal can is shown in W014059452 A1. Other examples are JP2013189244 A2, US2011272417 AA and EP2367733 B1.
    However, other alternative embodiments are sought which provide different benefits.
    It should be noted that other containers are available in the prior art which share some technical features with the current invention, but which seek to solve a different technical problem. In many cases, these patent documents are related to providing openings in the container to allow the product to be taken out of the container. These prior art containers are not provided to first pour liquid out and then remove the food product. Some examples are FR2903041, FR2927314, FR2859457, JP3098845, FR2281282, FR2841817, JP1029176 U1 and JP60139790 U1.
    Still others are provided whereby a utensil is stored in a compartment in the container. These containers also share technical features, but are again related to an unrelated technical problem. Examples of these are provided in EP1038790 A1, EP1092644 B and EP2241515 B1.
    Summary of the invention
    Accordingly in a first aspect of the current invention, it is desired to provide a container according to the introductory paragraph, where the lid is faster and cheaper to manufacture.
    In a second aspect of the current invention, it is desired to provide a container according to the introductory paragraph, which allows easy removal of the liquid in the container.
    In a third aspect of the current invention, it is desired to provide a container according to the introductory paragraph which is at least partially reclosable after first opening.
    The current invention provides solutions to at least some of these aspects via the features disclosed in the characterizing portion of claim 1. Additional beneficial features are disclosed in dependent claims 2-10.
    In the claims, it is stated that the central lid portion comprises at least two drain openings. In another embodiment, the central lid portion can comprise at least three, at least four or at least five drain openings.
    It should be noted that according to the current specification the term "peelable" should be understood to mean an interface which establishes a good firm connection between two elements, but where the interface can be broken in an easy manner without damaging the two elements. The term peelable is well understood in the prior art and different materials are known which are suitable. In general, it can be noted that two main classes of peelable compounds are known in the art. A first class comprises plastic materials which establish poorer adhesion to other plastic materials. A second class comprises adhesives which provide poorer adhesion between two different plastic materials.
    In one claim, it is stated that the drain openings cover at least 20% of the surface area of the central lid portion. In another embodiment, the drain openings could cover at least 30%, at least 40% or at least 50% of the central lid portion. Likewise, there is a claim which states that the drain openings cover less than 80% of the surface area of the central lid portion. In another embodiment, the drain openings could cover less than 70%, less than 60% or less than 50% of the central lid portion. Different combinations of the limits could be imagined.
    It should be noted that the claims define a container with a container body and a lid. In another embodiment, claims could be formed which are directed at a container according to any one of claims 1-10, where the container is filled with a combination of liquid and food products, where the dimension of the food products is greater than the dimension of the drain openings. A claim could also be formed directed at a lid suitable for a container as defined in claims 1-10.
    It should be emphasized that the term "comprises/comprising/comprised of' when used in this specification is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.

    In the following, the invention will be described in greater detail with reference to embodiments shown by the enclosed figures. It should be emphasized that the embodiments shown are used for example purposes only and should not be used to limit the scope of the invention.
    Detailed description of the embodiments
    The figures show a single embodiment of the invention, however additional embodiments are disclosed in the text of the description below.
    The figures show a container 1, having a container body 2 and a lid 10. The container body 2 has a bottom 4, side walls 5, an opening 6 and a rim portion 7 delimiting the opening. The lid 10 has a rim portion 11 and a central lid portion 12. Drain openings 13 are formed in the central lid portion 12. A peelable cover element 14 in the form of a peelable IML covers the drain openings.
    In the embodiment shown in the figures, the drain openings 13 are shown as elongated slots formed in the central lid portion 12. Elongated openings will be less likely to be plugged with food product during pouring since a larger area is provided. Elongated openings will also be useful in other embodiments of a container according to the invention. However, other forms of drain openings could also be provided. In one example (not shown), drain openings are provided in the form of a grate having a number of openings arranged in a rectangular grid. In another case, a number of circular holes are placed close to the edge of the central lid portion. In another embodiment (not shown), the drain openings are provided as slots arranged parallel to the rim placed at different offsets from the rim.
    The drain openings are in this embodiment arranged along the outer portion of the central lid element. This will also be true for many other embodiments as it will be desired to pour the liquid out of the container through the drain holes by tipping the container so that the drain holes are located below the rest of the container. Hence, placing the drain holes along the outer portion of the central lid portion, close to the rim of the lid is beneficial in many cases.
    In this embodiment, the rim portion and the central lid portion are injection moulded as an integral injection moulded element. In the current embodiment, the cover element is in the form of a peelable In Mould Label which is placed in the injection moulding form prior to the injection moulding of the rim and central lid portion. During the injection moulding operation, the surface of the cover portion which is in contact with the injected plastic material will fuse to the central lid portion. Due to the choice of materials (as is well known in the art), after the lid has cooled, the cover element is firmly attached to the central lid portion. However, again due to the choice of materials, when a user applies force on the cover element, it is possible to "peel" the cover element off the injection moulded central lid element.
    Peelable in mould labels are known in the art and won't be described in detail in this specification.
    In the current embodiment, the cover element 14 is provided with a tab 15 which is folded over onto the cover element. When the user wishes to remove the cover element, the user takes hold of the tab and pulls, thereby pulling the cover element off the lid and thereby exposing the drain openings.
    In figure 3, some additional details of the cover element are shown. A straight dashed line 16 is shown to illustrate two different portions of the cover element. A first portion 14 is made from a peelable IML material where the bond formed between the central lid portion and the IML is peelable. The second portion 16 is not peelable. As such when the user applies force to the tab, the peelable portion 14 is peeled off the central lid portion, but when the peel reaches the dashed line, further peeling is prevented. In this way, the cover element remains on the lid and is not completely removed. Releasing the force on the tab, will let the peeled cover element relax and again cover the drain openings. While a liquid proof seal is not re-established, the cover element again covers the drain openings.
    Figure 3 also shows two dotted circles 17 in the cover element. In this embodiment, the dotted circles denote areas where there are weakened portions of the cover element. When the cover element is peeled off the lid element the weakened elements break, thereby showing evidence of tamper. Other embodiments could also be imagined, for example, the peelable cover element could connected to another portion of a cover label via perforations whereby in order to remove the cover element, the perforations would need to be broken.
    Figures 1 and 2 show a tamper proof element 20 which is arranged between the lid and the container body. In order to open the lid, the tamper proof element has to be broken. In certain embodiments, one could imagine a tamper proof element between the lid and the container body and a second tamper proof element between the cover element and the lid portion.
    In the current embodiment, the lid has been shown with a integrally injection moulded rim portion and central lid portion. The drain openings were thereby provided in the injection moulded central lid portion. In another embodiment (not shown in the figures), one could imagine a lid with an injection moulded rim portion and a multi layer foil central lid portion. The multi layer foil central lid portion could be in the form of an IML placed in the mould during injection moulding of the rim portion. The multi layer foil could be provided with drain openings in the lower layer and a top layer which is peelable from the lower layer. When the top layer is peeled off, the drain openings are exposed.
    In the embodiments disclosed above, the cover element has been a flexible foil like element. However, in certain embodiments, the cover element could be a stiff element which can be peeled off the central lid portion, and then later on refastened to the central lid portion. This could for example be via snap connections on the rim portion of the lid.
    It is to be noted that the figures and the above description have shown the example embodiments in a simple and schematic manner. Many of the specific mechanical details have not been shown since the person skilled in the art should be familiar with these details and they would just unnecessarily complicate this description. For example, the specific materials used and the specific injection moulding procedure have not been described in detail since it is maintained that the person skilled in the art would be able to find suitable materials and suitable processes to manufacture the container according to the current invention.
