Description j Closure for cylindrical containers made of plastic film

Bel the production of containers from plastic film or when "spanking such containers, the task often occurs on, a cylindrical container part with a flat bottom or cover to connect. Original use of the sweat and The sealability of the plastics is often followed by the cylindrical container part with a flat one provide a protruding edge see below and place a flat cover (Fig. 1) or an impression cover with a flat edge against it The two cursing edges are then removed in the locking device swei annular halves of a tool W captured and under Application of pressure and heat iait linked, if necessary with the help of one of two container parts attached heat-sticking subetans.

The advantages of this way of spilling are:

simple form of the sealing device, in which only «white Halves of a tool are moved against each other

easy insertion and removal of the container from the Locking device

The Hachtdile are s

high space requirements for stacking and packing such containers the protruding edge can lead to damage

the junction is a flat seam and as such claimed for division

A supply mode would be better in which the two container parts not on a flat circular trellis, but on an annular strip of the cylindrical container parts are connected to each other, Fig. 2 · When such a closure is needed the child's back cover is only secured against sliding, see below its »where a light tacking can be enough« The space required by finished containers «with the lake closure is less than when using the flat protruding closure edge

However, in order to produce such a closure, the parts of the tool Ib closure device had to exert a pressure in the radial direction (Fig. 2), which made the construction of the device considerably more complicated and required a very careful and cumbersome insertion of the container parts into the closure device would force. This type of closure has therefore not yet been used in practice for containers ηas plastic film.

The present invention relates to a learning circuit, feel dem the connection point of the two container parts lies on an almost cylindrical ring strip, so that all the advantages of this Fora come into their own without losing the benefit of the simple Spoillessens would have to be disclosed "

What is essential here is the consideration that sum connect del both container parts pressure and '"tirae applied" earth out, uud duaa nan can also use these means at the same time, slightly deform the plastic film.

According to the invention, the cylindrical part Z (Fig. 3) of the container is only slightly widened at the end and, if necessary, beaded about to the outside. Hr is then inserted or hooked into a loosely fitting support ring R together with the push-in cover E, which can also be unthreaded a bit like nuts. The support ring forms aen. a part of the Verachlusewerkzeugs against which the other part moves in Fora a · slightly conical punch S.

To generate the required high tea temperature at the The connection point can be heated by the Stiltsri ng or the oteiapel be, or it can uochfrequena-ünergie for the application icoataen, or a combination of these possibilities can be used.

When leasing, the stamp breaks the impression cover «Uuacaat something in front of you and expand beyond what he was Edge of the Jehaltera as long as it is full of aa 3tataring. Afterwards, every further force exerted on the oteapel acts as a radial pressure on the connection point and presses both container parts toaaaaen over the entire circumference, whereby the contact surface of the two parts is an almost cylindrical one annular strips swisehen support ring and stamp forms.

Not only the widening, but also the initial slight difference in the impression decoration "" and later the slight: ii; ie, the gap between the support and the stamp is desirable and important because the plastic has become soft during the period -Material is kneaded and rubbed and veiled over the good contact surface, which has a very beneficial effect on the strength of the seam.

Deia retracting the ϋΐβώρβίβ you need nothing easy to lift the container to loosen uj »iiia in 5tdtxring again and küruaeü comfortable heraasziehaen 2α.

This closure combines the advantages of the flat protruding Versonschlussrand sit those of the radial attachment of a pressing cover aa cylindrical container part, and is free from the divisions of both versions.

Claims (2)

Schutan claims 1. Closure door cylindrical container made of plastic film using a binding press deekele, characterized in that both container parts are connected to each other when closing, wiping a stub ring which loosely encompasses the cylindrical container part, and a weakly conical stamp moved against it using sound pressure and ffärae «If necessary with the help of an adhesive substance attached in between. 2. Closure according to claim 1, characterized in that the slightly conical stamp the heated I: and the cylindrical Container parts at the beginning of the sales process initially until it rests against a »3tut« ring eatt »whereupon the} £ iudruckdeckol by dun Steapyl naliesu radial aa ganssen Perimeter is pressed against the cylindrical Beiialtarteil. 3 »Proposal according to claim 1 , characterized in that the hot adhesive substance is applied in the form of a coating or a layer on the pressure-sensitive lid or on the cylindrical container part or on both where the two container parts touch when closed. 4 · Yerachluee according to claim 1, characterized in that the container parts at »close against each other and move slightly against the support ring and move it, whereby the softened plastic material at the connection point in see kneaded and over the whole contact surface of the container parts - is rubbed and smeared.
