Definitions
- the invention relates to a plastic container with a stackable, can-shaped container body and a stackable lid, which connects tightly against the container body when the container is first closed and which can be removed from the body for opening the container and repeatedly placed tightly on the body for reclosing, with one on the edge of the container Molded-on guarantee ring which engages under a circumferential projection on the outside of the container body and which can be detached from the cover at a pull tab.
- Plastic containers of this type are generally known and have also proven themselves as packaging for paints. Because these containers are manufactured in very large numbers it would be essential for economic and ecological reasons that it can be manufactured from as little plastic as possible. Despite the most economical use of plastic, however, the tightness should be ensured, especially when the container is to serve as a dye container and is exposed to reduced external pressure for a longer period of time, for example, when transported in an aircraft.
- the invention has for its object to provide a container of the type mentioned, which can be produced from less plastic, in particular by injection molding, and which can also be used as a dye container.
- the object is achieved in a plastic container of the type mentioned in that the guarantee ring has a plurality of openings which are arranged at a distance from one another in the circumferential direction of the cover and that comparatively narrow webs, each delimiting an opening below, are formed on the guarantee ring, each on the inside have a tooth-shaped extension which engages under the projection on the outside of the container body.
- the teeth that engage under the projection of the container body are formed on comparatively narrow webs.
- the guarantee ring has a breakthrough above each web, which can extend to the upper edge of the guarantee ring.
- the above-mentioned webs form a kind of snap connection with the teeth, which are tensioned on the mentioned projection when the cover is first put on and engage on the underside of this projection.
- the webs are preferably distributed approximately uniformly over the circumference of the cover. The lid is then anchored to the container body at several points solely by the engagement of the webs or the teeth formed thereon.
- the container 1 shown in partial section in FIG. 7 is made entirely of plastic, for example polypropylene, and has a can-shaped container body 1b and a lid 1a.
- the preferably circular container body 1b consists of a flat bottom 6 and a conical wall 7 which ends in a likewise circular edge 8.
- the edge 8 has a circumferential bead 20 projecting outwards and a projection 4 likewise projecting outwards.
- the projection 4 is interrupted at a gap 11, as indicated by broken lines in FIG. 3.
- the L-shaped projection 4 according to FIG. 4 is stiffened on the underside by a plurality of radially extending webs 21.
- the edge 2 of the cover 1a has an annular groove 22 which is open to the inside 23 of the cover 1a.
- a circumferential rib 12 projects into the channel 22 and has an oblique sealing surface 12 a which, when the container is closed, also inclines on one Shoulder 9 of the bead 20 abuts.
- FIG. 7 shows the engagement of the bead 20 in the groove 22 and the contact of the sealing surface 12a on the shoulder 9.
- a ring-shaped and circumferential, closed guarantee ring 3 is also formed on the underside.
- the guarantee ring 3 is formed with a plurality of punctiform webs 14 on the projection 13.
- a connection in the form of a thin film hinge is also conceivable.
- a tear-off tab 5 is formed on the outside of the guarantee ring 3, on which the guarantee ring 3 is cut by hand at a weak point (not shown here) and can be separated from the cover by breaking off the punctiform connecting webs 14.
- the guarantee ring 3 has a plurality of rectangular openings 16 and between them also rectangular plate-shaped wall parts 15. Adjacent wall parts 15 are each connected by a comparatively narrow and flexible web 17.
- Each wall part 15 is in each case attached to the cover 1a by at least two connecting webs 14.
- the wall parts 15 are thus movably attached to the cover 1a in a manner similar to a hinge. When the cover is attached, however, these parts 15 rest against the outside of the projection 4 under elastic tension.
- the Teeth 18 anchor the lid 1a to the container body 1b in such a way that the lid 1a can only be lifted off after the guarantee ring 3 has been removed.
- the number of webs 17 depends, of course, on the circumference of the cover 1a. In the case of a container 1 with a content of one to about two liters, at least ten, preferably thirteen to twenty, webs 17 are provided. The length of the webs 17 is then preferably about 1 to 2 cm.
- the lid When the lid is closed for the first time, it is placed on the edge 8 of the container body 1b from above.
- the respective inclined inner sides 18a of the teeth 18 slide downward on a conical outer side 4a of the projection 4, the guarantee ring 3 being tensioned at its lower edge.
- the guarantee ring 3 When the cover 1a is fully attached, the guarantee ring 3 is tensioned in the area of the webs 17, so that the teeth 18 are held securely in their engaged position.
- the webs 17 and the wall parts 15 thus form a closed ring 3, which is formed on the cover 1a via a plurality of punctiform webs 14 and which preferably rests under elastic tension on the container body 1b.
- the openings 16 and also the wall parts 15 can be shaped differently, and it is also conceivable that the wall parts 15 are integrally formed on the cover 1a via more than two webs 17 or with a film hinge.
