Definitions

• the invention relates to a container, consisting of a container body and a lid connected to it.
• the state of the art describes a wide variety of containers of various forms, such as bottles, tubes, tubular containers, etc., in which the dispensing aperture is closed with a lid, especially a snap-fit lid.
• a fundamental distinction is made here between containers in which the container body and lid are separate from one another in the non-closed state, i.e. the lid no longer has any connection with the container body after opening, and those containers, in which there is still a comiection between the lid and the container body in the opened state.
• this connection can be made in a variety of ways.
• One preferred possibility, especially in the case of tubular containers, is to form the container body and lid integrally. These integral embodiments are usually manufactured by injection moulding. In this case, it is inevitable that the container body and lid are made from the same material.
• the object of the invention is therefore to create a container of the generic type in which the connection between the container body and lid is more stable and reliable than what was l ⁇ iown in the state of the art.
• a container of the generic type comprising a container body and a lid connected to it, wherein the container body and lid are manufactured separately, the container body having a recess or projection in or on its outer wall adjacent to its dispensing aperture, and the lid having a connecting land extending outwards from its peripheral rim, with a projection or recess provided at the end of the land distal from the lid, which can be brought into engagement with the recess or the projection on the container body.
• the end of the connecting land distal from the lid is designed such that, in the assembled state, said end lies substantially flat against the outer wall of the container body.
• the container body is formed substantially cylindrical and the lid substantially round.
• the invention further provides that a hinged connection is provided in the region of the connecting land of the lid.
• the container body and/or the lid consist substantially completely of plastics material, the container body preferably consisting of a different plastics material from the lid.
• the container body and/or lid are preferably produced by injection moulding in this case.
• the container of the invention unites the advantages of the known two-part container type with those of the known one-part type.
• the invention provides a container with a stably hinged lid, which remains firmly connected to the container body even when the container is in the opened state.
• the plastics material for the lid it is only necessary, for example, for the plastics material for the lid to contain additives which make it possible to achieve enhanced flexibility in the region of the hinged connection, e.g. a film hinge, such as certain plasticisers, whereas these additives are not necessary for the container body, which reduces the costs significantly.
• Fig. 1 shows a perspective view of an embodiment of a container body for the container of the invention
• Fig. 2 shows a lid suitable for the contamer body of Fig. 1;
• Fig. 3 is a cross-section though the lid of Fig. 2.
• Fig. 1 shows a container body 10 with a substantially cylindrical basic shape. At one end, the container body 10 has a dispensing aperture 12, whereas the other end 13 of the container body 10 is closed. Adjacent to the dispensing aperture 12, a peripheral flange 15 is formed on the outer wall 14 of the container body 10, which has a recess 16 in one portion.
• Fig. 2 and Fig. 3 show a lid 20 suitable for connecting with the container body according to Fig. 1.
• the lid 20 is designed substantially round and has an internal diameter which corresponds approximately to the external diameter of the container body 10, so that it is possible to seal the dispensing aperture 12 of the container body 10 simply by pressing on the lid 20.
• the lid 20 has a tab 22 (which can be of any design), which serves in particular to open the container.
• a connecting land 24 extending outwards from said rim, the land having the material with a thinner portion (in a position substantially central and transverse to its radial extent), said thinner portion having the function of a film hinge 25.
• a projection 27 which runs substantially perpendicularly to the connecting land 24.
• the end 26, or the projection 27, are slightly curved in the transverse direction, namely corresponding to the curvature of the outer wall 14 of the container body 10.
• engaging lugs 28 can preferably be provided.
• the container body 10 and lid 20 After the container body 10 and lid 20 have been manufactured separately, they can be assembled into the complete container at any suitable time by inserting the projection 27 into the recess 16 and anchoring it there by means of the engaging lugs 28. In this way, a firm connection is created between the container body and the lid.
• the lid 20 can be swivelled about the film hinge 25 in such a way that a secure closure of the dispensing aperture 12 in the container body 10 is achieved.
• the peripheral flange 15 can serve as a stop for the lid 20.
• the material used both for the container body and for the lid is polypropylene, which can be processed in the range from 200 to 300° C.
• the polypropylene for the lid can also have a conventional commercially available plasticiser added to it.
• the container body which is cylindrical in the case of this example, and the rounded lid, the dimensions of which have been adapted to the body shape, are produced in two separate moulds, with a plurality of each part being contained in a mould.
• a conventional injection moulding process is used for production.
• the parts are ejected mechanically onto a belt by means of a scraper.
• the two parts are delivered separately to an assembly station, where they are aligned and subjected to a handling process in which the two parts are brought together. After that, the closure is performed mechanically.
• the injection moulding step and subsequent processing can be carried out completely independently of one another.
