DD154687A1 - WIDE THRESHOLD FOR FAESSER - Google Patents

Abstract

The invention "Wide-necked closure for Faesser" refers to wide-mouth container made of plastic material with molded on the neck neck outer cam and the opening cross-lids, which is segmented in the outer area. In this case, a sealing element is arranged between the upper edge of the barrel and a ring-shaped lid groove. The lid segments are locked in the closed position below the neck lugs by a clamping device. The aim is to create a fluid-tight and high mechanical loads resistant closure. Essential features of the invention are the assignment of a respective neck cam to a lid segment which receives the neck cam in a breakthrough and the straight-line connection of the lid segments to the upper lid level. The clamping device holder is formed by a lower rib-shaped breakthrough boundary and by outer, facing segment tongues. The application of the invention is limited to the field of transport packaging made of plastic with a large opening cross-section.

Description

Wide neck closure for barrels

field of use

The invention relates to the closure of w'eithalsgebinden plastic material j 'for transport and storage of different Püllgüter be completed with a plastic lid. Such packaging materials, which are also referred to as lidded drums, must meet high requirements for tightness and mechanical strength »

Known solutions

It is known to lock the edge segments of a plastic cover which overlaps the fitting opening by means of a tensioning band below fitting projections. The cover segments are in each case positioned between the projections on the fitting neck. The cover comprises an annular collar dipping into the fitting and a hat receiving the fitting opening edge with a sealing element on (DE-GM 6937508) · A variant has become known to continue (DE 2258096) provides for integrally molded Paßhalsnocken before a dimensionally stable cover design. As clamping means, a Peder steel wire with a circular cross-section alternately arrives at the outer segment surfaces and the lower sides of the cams. It thus stresses the fitting body in this region. Puristically characterizing this design is also the relatively strong retracted lid base, which is in the closed position in a plane

is located with an inwardly curved circumferential Paßhalssicke. This entails the danger that, in the case of closure application, ZoB. by Pail or push the lid can be easily pushed out of its tense position.

Object of the invention

It is to be created a wide-neck closure, which meets the requirements for leaktightness and high mechanical strength of plastic barrels. The barrels should retain these functional properties for multiple use over a long period of time and. to make it possible to close without increasing the expenditure of living and objectified work. "

Essence of the invention

The technical problem to be solved is the combination of the advantageous Zusammenwikens Deekelsegmenten and Paßhai svorSprüngen with new features. In this case, the cover construction with respect to an elastic lock to change and to allow the use of other than wire-shaped clamping means.

This object is achieved according to the invention, that each a squatting of the Paßhalses a lid segment is assigned. The segments have a straight-line connection to the upper lid level and form a polygon in the axial plan view. An essential feature of the segments is also their preferably etv / a rectangular breakthrough for receiving the neck cam in the closed position. This breakthrough is bounded laterally and down by a rib reinforcement. At its edge open the lid segments in externally molded, upwardly facing tongues, which form together with the lower rib of the opening the Spanmnittelhalterung. Pur the inclusion of the Mebelverschlußteiles on the clamping means are formed in individual lid segments, the tongues only in the approach. ,

Embodiment ι

The invention will be explained below with reference to a polyethylene 1001 wide neck drum. In the drawing show

Fig. 1 shows a cut in the plane of a neck cam fitting head in the closed position

Pig. 2 is a half-cut view of the fitting head Pig. 3 the top view of the lid ·.

The fitting body has an adjacent to the spherical portion of the container cylindrical Paßhals, which serves with specially shaped neck cam 2 locking the Paßdeckels 4 * The Paßdeckel 4 extends about one third of the total cover height into the Paßinnere inside, being pulled by the hine-r Cover part is provided a storage area for a further stacked passport.

To achieve a secure stacking and to compensate for internal surge forces that occur in a Pail-, or Sto.ßbeanspruchung the container, the retracted lid surface is slightly curved and provided at the edge with a circumferential Stapelringnut «

The over the opening edge. 3 of the pass overall edge of the lid is executed dodecagonal.

At each of the twelve flat side surfaces is followed by an elastic intermediate piece 15 with a reduced wall thickness down to a provided with a rectangular opening 10 cover element 9 at.

The in the lower and lateral edge region, reinforced by ribs 11,12 apertures 10 of the de-crème segments 9, corresponding neck cam 2 on Paßhals'' assigned. The lid segments 9 v / earth in their lower corner area bounded by tongues 13, the down and. form the outside of the recording for a clamping means 14. In this case, the lower tongue part is reinforced by ribs, while, the outer tongue end is designed to facilitate the replacement of the clamping means elastic, to receive the Hebelverschlu.ßelementes of

Clamping means I4 are two Deckelgeginente 9 executed without outer tongue ends and the remaining tongue parts offset downwards.

The lid segments 9 are inclined with open clamping means at a certain angle to the lid axis, so that the neck cam 2 dive only slightly into the openings 10 and the removal and placement of the passport cover 4 is not hindered on the passport ..

When closing the clamping means 14, the individual cover segments 9 move in the direction of the fitting axis with the lower rib 12 slides along the inclined ünterkante of the neck cam and thereby pulls the Paßdeckel 4 on the fitting body. The seal of the pass is made by a circular sealing element 6 which is inserted in a circumferential lid groove 5 and. the closed passport rests on the opening edge 3 of the passport.

The lid groove 5 is formed by the wall of the inner lid edge and a rib extending parallel thereto, which partially binds to the flat side surfaces of the outer Paßaußenrandes.
