Definitions
- ABSTRACT Lid for a container holding fluid contents, having an opening for pouring and an opening for admitting air. These openings are sealed on the side of the lid facing out from the container, with a strip of foil joined to the lid. The strip of foil exhibits a feature of originality to show that the container has not been opened in any way at these openings.
- TAMPER PROOF SEAL FOR A CONTAINER The inventionconcems a lid for a container which holds fluid contents, the said lid having an opening for pouring out the contents and an opening for admitting air, whereby the said openings are sealed with a strip of foil attached to the side of the lid facing outwards from the container.
- lid designs For containers for such fluid contents as drinks or oil for example there are basically two well known lid designs. They differ in that one type has incorporated in the design a device to form an opening for both admitting air and for pouring whilst in the other design the openings are already provided in the lid and are subsequently sealed with a covering.
- the first kind is preferred for contents which are constantly under pressure whilst the latter is used for contents under normal ambient pressure.
- the device for producing a combined opening in the lid for admitting air and for pouring consists of a lever device by which means an opening is produced automatically in the lid at the opposite end of the lever from the part which is raised.
- an opening is made on tearing away a part of the lid by means of a suitably designed lever device.
- the aim of the invention presented here is to produce a suitable covering for a lid for example in the form of a strip of foil which permits the junction between the covering and the container to be checked easily for damageand the object is fulfilled by way of the invention in that the strip of foil exhibits a feature of originality.
- a feature of originality is to be understood every measure which allows a manipulation of the strip of foil leading to exposing the opening by loosening the junction of the strip of foil to the lid to be recognized without particularly close inspection being necessary.
- the invention is advantageously so designed that the feature of originality consists of a line of weakness which divides the strip of foil into sections.
- Clearly visible lines of weakness arranged on the strips of foil present subconsciously to the user focal points for handling the seal, sothat a check on the seal can be limited to the region at and around the lines of weakness.
- at least two flap-shaped sections are formed which, on peeling away from the container, expose the opening for admitting air and for pouring.
- the lines of weakness consist of a series of perforations spaced apart and passing through the strip of foil. This way the sections are joined together and, by reducing the cross section, the tearing-off is 2 made easier. Since there are bridging pieces between the perforations these bridging pieces are broken when the strips of foil are manipulated, allowing the user to conclude that the contents may be impaired and he can then either decline purchase of the container or make use of the contents.
- the invention is further improved in that the line of weakness is arranged to connect the long edges of the strip of foil. This way a shorter cutting path is achieved by making use of a natural division of a strip.
- the division is to advantage made easier in another design in which the line of weakness runs at an angle to the long edges.
- the line of weakness and therefore the path along which the tearing takes place is longer by an amount depending on the angle but it has been shown that the tearing then takes place without any problem.
- a further improvement of the invention is characterised in that the line of weakness runs on both sides into open recesses. Because of these recesses, manipulations of the strips of foil are concentrated even more on the line of weakness.
- FIG. 1 a lid provided with a strip of foil in accordance with the invention
- FIG. 2 a sectioned side-view of the lid shown in FIG. 1
- FIG. 1 shows by way of example a lid, designed in accordance with the invention, for a round container.
- the lid can be adapted however for containers of different shape.
- the lid 10 For the purpose of emptying the contents out of the container the lid 10 possesses an opening 11 for pouring and an opening 12 for admitting air.
- the pouring opening 11 and the opening 12 for air are sealed by means of a strip of foil 13 which is torn away from the lid 10 to allow the contents to be used.
- the lid and the strip of foil and the container too can be made of various non-metallic or metallic materials. Furthermore various combinations of materials can be used for lid and foil strip. It is however preferred to manufacture the lid and foil strip out of a metallic material, in particular aluminium or an aluminium alloy.
- the joining of the foil strip and the lid can among other things take place by applying an adhesive.
- an adhesive In the case of a metallic lid and foil strip, before sticking the parts together there is a pre-treatment to allow better bonding between the two metallic faces.
- the pre-treatment includes the application of an adhesive, or in the case of aluminium a special chemical treatment of the surfaces is carried out.
- plastics polyvinylchloride, polyolefine, polyester, polyurethane, epoxyresins, polymers of ethylene grafted with acrylic acid and polyamides of dimeric fatty acids have been shown to be suitable meltible plastic layers for the purposes of the invention. If the contents of the container have to be subjected to sterilization it is preferred to use as meltible plastic a polymer of ethylene grafted with acrylic acid or a polyamide.
- plastic layer 0.01 to 0.1 mm thick is applied to the strip of foil, whereby the thickness of the strip of foil can amount to 0.02 to 0.35 mm.
- the thickness of plastic layer and foil strip are determined by the strength of junction required between lid and strip and depends on the contents of the container.
- a flanged edge 19 with which a suitable ledge at the free peripheral edge of a container (not shown) engages and the two parts are then rolled together to join the lid 10 to the container.
- the strip of foil 13 is provided with a line of weakness 15 which runs between the long edges of the foil strip 13.
- the line of weakness consists of a series of perforations side by side, passing through the strip of foil 13, and having between them bridging pieces of foil.
- the line of weakness 15 runs at an angle of 45 to the long edge of the strip of foil 13.
- the line of-weakness 15 runs on both sides into recesses 18 provided at the long edges of the strip 13.
- a region 20 which is not joined to the lid In these regions no junction between the strip 13 and the outside of the lid 10 is made.
- the region not joined to the lid are those between the broken lines 20, through which the line of weakness runs diagonally.
- Each of the areas is provided with folds 21, which allow better gripping of the sections 16 and 17 which are in the form of flaps after tearing along the line of weakness l5, and allow the opening 11 for pouring and the opening 12 for admitting air to be exposed.
- a lid for a container holding fluid contents including a body having an opening for pouring and an opening for admitting air, and a strip of foil connected to said body and disposed for sealing said openings on the side of said body facing out from said container,
- said strip of foil consisting of sections divided by a line of weakness to exhibit a feature of originality to show that said container has not been opened in any way at said openings.
