Description

Technical Field

[0001] The present invention relates to a closure made of plastic having wings that project radially outward from the side of the closure and are fastened to the closure on opposite diametrically opposed sides, wherein each wing transitions from a fastening area located near the closure to an actuation area further adjacent to the outside and for manual actuation. Background Technology

[0002] WO 2007 / 002292 discloses a screw-on closure cap on which two wings, serving as gripping surfaces, project radially outward on opposite sides of the cap's diameter. In cases of hard threads, jamming, or to damage tamper-evident seals, it is often necessary to manually apply a large rotational force to the closure cap, which may cause the gripping surfaces to bend or break. Summary of the Invention

[0003] One object of this invention is to improve the type of closure described in the introduction, giving it high strength and rigidity while maintaining a simple structure. Here, the closure should provide a good and comfortable grip.

[0004] According to the invention, the objective is achieved by having the fastening areas of the two wings arranged rotationally symmetrically on both sides of a central plane passing through the axis of rotation of the cover.

[0005] This lateral arrangement of the fastening area relative to the center plane achieves high strength of the wing on the closure, allowing high rotational forces to be manually applied to the closure without significant deformation or breakage of the wing. It also enables comfortable operation.

[0006] These advantages are further enhanced if, in a view perpendicular to the lid's axis of rotation pointing toward the lid's lateral outer surface, the fastening area of ​​each wing transitions from a recessed curved area relatively far from the lid to a convex curved area relatively close to the lid, wherein the convex curved area closely abuts the lid's convex lateral outer surface and / or transitions to the lid's convex lateral outer surface in a continuous manner.

[0007] If at least one support or tongue protrudes from the side of the cover outwards, the strength of the wing on the closure cover is further increased, with the outer end of the support or tongue integrally formed on the outer surface of the wing. It is proposed that the support or tongue be formed in a hollow shape, with its cavity opening to the rear side of the wing. This hollow shape reduces weight and the cost of the closure cover material, and provides a comfortable grip as a finger recess. Furthermore, it is suggested that the rib, support, or tongue, in its embodiments, be confined to the concave wing fastening area, or extend beyond that area into the vertical actuation area.

[0008] Regarding the two actuation regions of the wing, as a possible embodiment...

[0009] Both actuation zones are located within the central plane of the cover's rotation axis.

[0010] - The actuation region is arched, such that the cross-section that transversely passes through the actuation region relative to its longitudinal extent forms an arch.

[0011] -The actuation region is arched in its longitudinal direction.

[0012] - The actuation area is arranged parallel to the central plane and has a lateral gap from the central plane.

[0013] Furthermore, the present invention proposes that the sealing cap is threadedly fastened to the pouring spout of the container, and that the sealing cap is connected to the pouring spout of the container via a tamper-evident seal. Attached Figure Description

[0017] Figure 3 shows a perspective view of a second exemplary embodiment, which has a straight section passing through the wing in the actuation region.

[0018] Figure 4 shows a side view of the actuation region with a fan-shaped cross-section.

[0019] Figure 5 shows a side view of the actuation region with a tortuous cross section.

[0020] Figure 6 shows a perspective view of the third embodiment. Detailed Implementation

[0021] The sealing cap 1 according to the invention is made of plastic by injection molding and has a cylindrical shell surrounding an internal space that is closed on its top side, allowing the sealing cap to be screwed onto the external thread of the container's pouring spout via its internal thread. Here, between the lower end of the sealing cap 1 and the sealing cap seat of the pouring spout, there is a tamper-evident seal 11 that breaks when the sealing cap 1 is first unscrewed, thereby indicating whether the seal has been opened.

[0022] In the embodiment according to FIG3, the boat-shaped welded portion 12 is integrally formed at the lower end of the pouring opening, and the welded portion is welded between the two side walls of the bag-shaped container.

[0023] Two integrally formed wings 2 protrude radially from the outer surface 10 of the cover 1 on opposite radial sides. In the embodiment according to Figures 1 and 2, these wings are located in a vertical plane 5, in which the vertical axis of rotation 6 of the cover 1 is also located. Here, the two wings protrude to such an extent that the cover 1 has such a large overall width that the cover cannot be swallowed by a child.

[0024] Each of the two wings 2 is integrally formed on the raised lateral outer surface 10 of the cover via a wing fastening region 3, wherein, in a view perpendicular to the axis of rotation 6 of the cover and pointing towards the lateral outer surface 10 of the cover, the fastening region 3 of each wing transitions from a recessed curved region a relatively far from the cover to a protruding curved region b relatively close to the cover, wherein the protruding curved region b is adjacent to the protruding lateral outer surface 10 of the cover 1 and / or transitions continuously to the protruding lateral outer surface 10 of the cover. Therefore, the fastening region 3 and its two curved regions a and b can be referred to as S-shaped in the top view.

[0025] In the case of two wings 2, the fastening region 10 is adjacent to the outside by a particularly radial, layered, vertical actuation region 4, which, in the embodiment according to Figures 1 and 2, is located in the vertical plane 5. However, the actuation region 4 may also be parallel to and offset relative to the plane 5, and may also be curved or arched in its lateral direction and / or its longitudinal range. Figures 4 and 5 show two lateral arches, denoted by S1 and S2, respectively.

[0026] Ribs, struts, or tongues 7 may be confined to the concave wing fastening region 3, or may extend beyond that region into the vertical actuation region 4, depending on their embodiments. Ribs, struts, or tongues 7 may also be combined in their embodiments.

[0027] To increase the strength and rigidity of securing the two wings 2 to the cover 1, at least one support, tongue, or rib 7 protrudes from the outer lateral surface 10 of the cover, extending outwards, and the outer end 8 of the support, tongue, or rib is integrally formed on the outer surface of the wing. The support, tongue, or rib 7 bridges the gap or void 13 existing between the securing area 3 and the outer lateral surface 10.

[0028] In the embodiment according to FIG3, the strut or tongue 7 is formed in a hollow shape, with its cavity 9 opening to the rear side of the wing 2. Furthermore, each of the two wings can be fastened to the lateral outer surface 10 of the cover by two or more struts, tongues or ribs.
