Container with detachable lid

The invention relates to one particularly for recording Container for liquids and viscous substances, which is closed by means of a detachable lid can be"

Plastic containers, preferably cup-shaped, for holding fruit juices, milk, yoghurt and the like usually have a deodorant consisting of a thin aluminum foil, which together forms a more or less airtight connection with the upper edge of the container, which is achieved by a mechanical Deformation of the lid edge or even a sweat "

These containers have the disadvantage that in the container between the surface of the container contents and the lid a relatively large amount of air remains, in particular because of their oxygen hardness adversely affects the contents of the container.

The invention is therefore based on the object of avoiding this disadvantage, which according to the invention thereby what is achieved is that the lid has a trough-shaped recess protruding into the container and the Side wall of this trough with the wall of the container Forms gap narrow width. In this way, the free surface of the inside of the container becomes narrow Ring area in the upper part of the gap is reduced, where * by the risk of adverse effects of the trapped Oxygen on the container contents is largely avoided »"

If such containers have a conically tapering cup shape, they can have a well-known catfish little space can be stacked while building of the lid has the advantage that the container after

partial removal of its contents again or can be closed less airtight.

The container and the lid are advantageously made of plastic, for example polystyrene, the processing of which makes the economical production of the Container and a connection of the container old to the DeIrkel in a known way, for example high-frequency or ultrasonic welding processes

An Eyrotnetrische arrangement of the deodorant is advantageous thereby obtained that on the outer surface of the side wall bssw * the side windings of the trough-shaped Deckele Yorßprüuge are provided, one after all Ensure that the sides of the gap are even in width.

the container has the shape of a kouiocliptt beaker and the gap daait the shape of an evenly tight ring _o

A simple removal of the lid without dcooen Zer « Interference is, according to a further development of the invention according to Eonetrulifcion obtained by the fact that the container on the painful upper edge a shoulder and the lid one Schul + er has overlapping edge, the type, 00985 2 / 1GO 1

that this edge has an outwardly extending, Ton the shoulder of the container a small distance in the axial direction having flange and a has upwardly open groove whose downward white " sender apex rests against the shoulder of the container and with this, for example, by welding is connectable, and furthermore of the type that the outer flank of the upwardly open groove in the flange and the inner flank of the groove merges into the side wall of the lid trough to form an edge.

The drawing shows an exemplary embodiment of the invention depicted in a Scottish manner.

ψ The cup-shaped container 10 has a radially outwardly projecting annular lip or shoulder 11 on its upper pouring edge _o The plastic lid 12 has the shape of a relatively deep trough with a flat bottom and an annular side wall 14. The wall 14 is located in the radial direction at a distance from the inner wall surface of the container and forms with this an annular space 15ο The edge of the lid extends over the shoulder 11 of the

Container and has an annular groove whose downward facing vertex (17) rests against the shoulder and is smoldered with this. You inner plank 18 of this groove merges with the formation of an edge in the side wall 14 of the cover and forms with it a downward widening annular space 19 »

The outer flank 20 of the groove (17) goes into one after outside calibration extending flange 21 over which of the Shoulder 11 of the container has an axial distance and thus forms an annular schiit2 22, which is about 2 na is wide and thus allows the insertion of a coin, and also has a depth corresponding to this coin, the flange 21 from the shoulder 11 of the container to be able to separate by tilting the coin., The The vertex 17 of the groove is so aligned with the shoulder 11 that the welded joint without too large Force and can be separated without hurting the cover au, so that it is easily lifted off and after partial removal of the container contents can be reused.

su can and in this way an annular gap of over « all of the same width are preferably three outwardly protruding on the circumference of the side wall 14 cylindrical bulges 23 are provided, which also have the purpose of reusing the cover to hold it in the container opening after the welded joint has been separated.

The container is filled in the illustrated embodiment, up to such a height with fluid 24 such that, when the ⁰ Deokel is employed, the liquid in the annular gap 15 to below a height 25 in the IAHE of GUeßrandes penetrates the container. In this way, the free surface of the liquid is reduced to a minimum compared to the case of a filling of the container which does not extend to the lower surface of the lid base 13.

The container can also be filled to the point that the liquid level is exactly at the level of the The pouring edge of the container is located. This is achieved in that a quantity of liquid is poured into the container which corresponds approximately to the capacity of the container. Then when the lid is inserted,

becomes a small amount of excess fluid and the Air is displaced, so that in this way all containers of this type are also filled with exactly the same amount of liquid will.

The formation of the trough-shaped cover 12 is the same A level floor area 13 also enables them to be stacked securely on top of one another several filled containers.

laugh if the cover 12 has been lifted off, it can be your side be placed that the Bodenfläohe 13 ieigt upwards. Liquid residue on the bottom of the lid or also adhere to the side wall, are collected in this way in the annular recess 19, so that the tape 21 of the lid, no liquid can get in, and so also, for example, the surface on which the lid is placed was laid «stays clean ·

The container is cufier for liquids also for intake of viscous and pulpy substances as well as eur absorption of such substances, which are filled in liquid state and later solidify or gel. In all cases, the adverse effect on the surface of the container contents as a result of the trapped air by the erfindungsgeaäfie training of the lid in extensive hatred avoided. 009852/1601
