Definitions
- the invention relates to a closing unit, consisting of a container shoulder, a container head for applying the ingredients and a closure cap, the closure cap being operated using the twist-lock function.
- Such a closure also known as a fractal closure, is provided for a container of any dimension and design to be closed by means of a cap, which has an integrated container head with an opening for the removal of meterable media.
- Closures of the generic type are known from DE 43 42 251 Cl and GB 2203 729. In these solutions, thread sections are distributed over the circumference of the container neck or container head, which correspond to analog thread sections of the closure cap.
- Each thread section additionally has a web or other clamping elements, via which or after a short rotational movement the clamping effect of the closure cap on the container head is achieved.
- the object of the invention is to simplify the locking mechanism and to limit the thread area to a narrow, unobtrusive zone on the container head. Furthermore, it is an object of the invention to arrange the first consumer protection, that is to say the freshness seal, in the closure unit in such a way that it is visible to the user from the outside.
- the thread segments are located in a narrow, possibly cylindrical foot area of the container head, which directly adjoins the container shoulder.
- the application cone then follows this foot area of the container head, which contains the thread zone.
- the thread segments designed as a simple rising thread can be linear, point-shaped or peg-shaped.
- the thread segments should be executed without edges and the like, but only with curves.
- the container head has a frustoconical shape in the area of the application zone, the threaded segments being arranged in the lower region on the container shoulder in such a way that, when the closure cap is screwed on, they engage in the thread present in the inner end region of the inner cylinder of the closure cap. With a small opening and closing angle, the closure cap that sits on the container shoulder in the closed position ensures good clamping properties for reliably fixing the closure.
- the cover plate of the closure cap has openings or windows in the region of the inner cylinder of the closure cap and a closure cover held over webs.
- This cap is arranged as a sealing and sealing surface concentrically within the cover plate and its diameter corresponds at least to the diameter of the container opening, so that the cap reliably seals the application opening when the cap is screwed on.
- the inventive arrangement of the fresh seal in conjunction with the described design of the cover plate of the closure cap enables the customer to convince himself of the presence of the fresh seal and thus the integrity of the product packaging even before first use.
- annular bead or the like can be provided to improve the closure properties of the closure unit, the outer diameter of which corresponds approximately to the inner diameter of the container opening.
- the shape and number of windows in the lock can be any. Any recesses that go beyond making the freshness seal visible serve to save material and / or a more advantageous design.
- the closure is removed by a maximum of 90 ° rotation and the fresh seal by pulling it off. Reliable tightness of the closure is guaranteed by the pitch, the material thickness of the thread segment and the clamping on the container shoulder. The breakaway torque during the opening process is low.
- the container head with the pronounced application cone and the edgeless structured thread is easier to clean; due to the container shoulder being kept as flat as possible, good residual emptying is ensured for non-dimensionally stable containers.
- the properties of the fastener to be emphasized are still the great ones Footprint, the minimized use of materials, the dimensionally stable inner cylinder with threaded segment counterpart and the ring bead, also for pressing and sealing the freshness seal; furthermore, there are no material hammer cuts, which ensures simple manufacture.
- 1 is a side view of the closing unit as a sectional view
- Fig. 3 is a top view of the sealing unit with the largest possible material cutouts in the cover plate of the sealing cap.
- 1.1 and 1.2 show the elements of the closing unit, namely the container head with a cylindrical foot region 2 and the adjoining application cone 3, the container shoulder 4 and the closure cap 5 from different angles.
- Container head 2, 3 and cap 5 are made of plastic, for example polyethylene.
- Two thread segments 1, designed as a simple rising thread, are located in the cylindrical foot region 2 of the container head.
- the cap 5, consisting of the inner cylinder 6, outer cylinder 13 and cover plate 7 is screwed onto the container head. 1.1 are in engagement with the corresponding thread in the end region of the inner cylinder 6 of the closure cap 5.
- the windows 8, 12 introduced into the cover plate 7 of the closure cap 5 are shown in plan views of the closure unit according to FIGS. 2 and 3. In the embodiment according to FIG. 2, only windows 8 for making the fresh seal 14 visible are introduced into the cover plate 7.
- These windows 8 are located in the diameter range of the inner cylinder 6 of the closure cap 5 and delimit the closure cover 10, which is connected to the remaining part of the cover plate 7 via webs 9.
- the diameter of the closure lid 10 is selected so that it covers the application opening 11 as a sealing and sealing surface.
- the fresh seal 14 is fastened on the end face of the application cone 3, sealing the application opening 11.
- FIG 3 shows an embodiment variant of the closure cap 5 with additional material cutouts and thus windows 12 in the cover plate of the closure cap 5. These windows 12 are introduced in the ring zone of the cover plate 7 between the inner cylinder 6 and the outer cylinder 13 and give a view of the container shoulder 4.
- the webs 9 here connect the closure cap 10 radially to the inner cylinder 6 and further to the outer cylinder 13 of the closure cap 5.
