Benefits of technology

[0015] 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. On the other hand, it is possible, by manufacturing the container body and lid separately, to choose different materials for these two components. In this way, it is only necessary, for example, for the plastics material for the lid to contain additives which make it po

Problems solved by technology

If, in order to avoid these disadvantages, one reverts to the two-part design of the container body and lid, there is, on the other hand, the disadvantage that, once the container has been opened, the lid might fall off or be lost.
If, despite having the li

EXAMPLE

[0026] 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. In order to facilitate the formation of the film hinge on the connecting land of the lid, the polypropylene for the lid can also have a conventional commercially available plasticiser added to it.

[0027] 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.

[0028] After the injection process, 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 i...

Abstract

A container, consisting of a container body and a lid connected to it, the container body and lid being manufactured separately. Wherein the container body has a recess or projection in or on its outer wall adjacent to its dispensing aperture, and the lid has 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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a national stage filing of PCT / EP2003 / 010457 filed Sep. 19, 2003 claiming priority to DE 102 46 086.8 filed Oct. 2, 2002. TECHNICAL FIELD [0002] The invention relates to a container, consisting of a container body and a lid connected to it. BACKGROUND OF THE INVENTION [0003] 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 connection between the lid and the container body in the opened state. [0004] In the latter case, this connection can be made in a variety of ways. One preferred poss...
