Description

ALL-LOCKABLE LOCKING ELEMENT FOR HOLLOW BODIES LIKE BOWLS, CAN, BOTTLES AND THE LIKE WITH A LID PROFILE THROUGH THE HOLLOW BODY PROFILE.

field of use

The closure element is to be used for all containers which are open on one side, but are closed after being filled with a liquid, a granulate or a pasty mass and, if necessary, are opened again non-destructively and then closed again. Such closure elements serve to prevent the filling material from uncontrolled exiting from the packaging, to take over an opening and reclosing function and to protect against transport influences and moisture, temperature changes and the like. to ensure. The type of closure is dependent on the contents, its consistency and the requirements that the contents place on the quality of the closure.

State of the art

In the case of reclosable closure elements, it is known to provide a profiled cover lip all around on the edge of the actual closure element base, which lip can be pressed over the profiled edge of the hollow body. If the closure element is to be removed again, it is necessary to press the cover lip again over the profiled edge of the hollow body. This is regularly associated with considerable difficulties, since there is no sufficient force application area Specifically high forces must be applied to the exposed edge of the lid lip. If this is done directly by means of the fingers, there is a risk that they will be injured. When using tools, on the other hand, there is a risk of damage to the hollow body or the closure element due to the localized force peaks.

Task, solution, advantages

The object of the invention is to provide a closure element of the generic type which avoids the disadvantages of known closure elements and is easy and safe to handle both by hand and by means of tools.

According to the invention, the object is achieved in that a handle, which protrudes beyond the lid lip, is formed on a closure lid with a profiled lid lip arranged at the edge, which can be brought into operative connection with a profiled bead arranged in the region of the opening of the hollow body an abutment can be positively brought into operative connection.

According to the invention, it is possible to produce, in terms of production technology, • simple closure elements for different hollow bodies, which are easy to handle, without the risk of injury to the operator or damage to the hollow body or the closure element.

Embodiments of the invention

In a development of the invention according to claim 2 the handle is flat with high inherent rigidity.

According to a development of the invention according to claim 3, the cover is connected at a distance to a clamping plate which can be pushed onto the hollow body to be closed and clamped thereon.

The clamping plate of the closure element is further in a development of the invention according to claim 4 as a round or flat plate-shaped blank made of hard rubber, plastic or the like. and has a central opening corresponding to the cross section of the hollow body to be closed, the side wall of which is conical in such a way that the opening section facing the cover is somewhat smaller than the cross section of the hollow body to be closed and the opening section facing away from the cover is the same size or larger than the cross section of the hollow body to be closed.

According to claim 5, the clamping plate ^is' by means of a side edge of the clamping plate and the cover plate integrally formed with the lid, respectively.

According to claim 6 as a further development of the invention, an eyelet is formed on the clamping plate and the lid, on which an or the like as a band, wire, chain. trained connecting element is attached.

In a further embodiment of the invention, according to claim 7, tongue-shaped grip sections of great inherent rigidity projecting from the lid lip at a distance from one another are formed on the lid as a handle.

According to claim 8, the cover lip is used as a cover plate

1TUR £ 4 the circumferential, obliquely arranged, straight flange is formed with a thickened area located at the free end section, the lower surface section of which is arranged parallel to the upper surface section d of the edge bead and whose surface section adjoining the lower surface on the inside is arranged at such an angle to the locking surface section of the edge bead, that when the lid is closed, the lid lip is supported all around on three spaced-apart edge bead-side surface sections of the hollow body.

In one embodiment of the invention, the clamping plate is designed as a molded part.

According to a further development of the invention, according to Claim 10, the clamping plate is designed as an annular blank sealingly fitting against the opening edge of the hollow body, on the outer circumference of which other stiffening segments are molded at intervals from one another. On the sealing cover, segment-like handles are formed on the circumference at a distance from one another such that the handles are arranged between the stiffening segments when the edge bead is pressed into the circular blank.

In a further embodiment according to claim 11, the stiffening segments corresponding to the thickness of the handles are vertically offset relative to the plane of the blank

Best way to carry out the invention

1 is designed as a cover 1, which is a known per se

Has cover surface 4, on the edge of which a circumferential cover lip 2 is arranged. This cover lip 2 can be pushed over the bead, which is formed in the region of the opening of a hollow body to be covered. A handle 3, which projects beyond the cover lip 2 and is arranged in the plane of the cover surface 4, is formed on the side of the cover 1. This closure element is particularly advantageous to use in the case of hollow bodies which have an external extension underneath the opening. If the closure element is to be removed from such a hollow body, this extension serves as an abutment, since individual fingers of the operator are supported on this extension, so that the lid 1 can be easily lifted by pressing the handle 3 with the remaining fingers. It is also possible to support a suitable tool on the extension of the hollow body and to bring it against the handle 3. Due to the resulting leverage the lid 1 is also lifted off the hollow body.

For hollow bodies without an extension formed below the opening, the use of the closure element 10 shown in FIG. 2 is advantageous. This closure element 10 consists of a cover la on which one

Handle 3 and a lid lip 2, as described in Fig. 1 ben, is formed and a clamping plate 5, which was in the Ab from the lid la is arranged. The clamping plate 5 is designed as a plate-shaped blank and has a central opening 6. The side walls 7 of the

Opening 6 are conical. It is advantageous to form the lower opening section 9 of the same size or slightly larger than the cross section of the hollow body to be closed, while the upper opening section 8 should be somewhat smaller than the cross section of the hollow body to be closed. As a result, it is easily possible to slide the clamping plate 5 onto the hollow body to be sent, the clamping plate 5 being deformed in the area of the upper opening portion 8 so that it clamps on the hollow body to be closed. The ceiling 1a is expediently connected to the clamping plate 5. This connection can be made in one piece by means of a tab which is formed on the De kel la and the clamping plate 5 or by means of a detachable connection. For this purpose, an eyelet 11, 12 is formed on the cover 1a and the clamping plate 5, on which a band, wire, chain or the like. is fastened as a connecting element 13. In this closure element 10, the outer edge portion of the clamping plate 5 serves as a derlager when the lid la is to be opened.

The closure element 20 consists of a cover 1b, de as the cover 1, la is formed. As a handle, the lid lip 2 is at a distance from one another, projecting toward the gen-shaped handle sections 14, 15, 16, 17 of large inherent rock

_O. Ability arranged in the plane formed by the cover Ib (Fig. 3). With this closure element 20, the opening of a hollow body closed with the closure element 20 takes place in that one of the tongue-shaped grip sections 14, 15, 16, 17 is arched. Here, the section of the lid 1b which is pressed particularly firmly onto the hollow body serves as an abutment, while on the opposite side of the handle section 14, 15, 16, 17 in question the lid lip 2 is lifted up. By pulling the handle section accordingly, the lid 1b can then be lifted off as a whole.

4a to 4c show an advantageous embodiment of the cover lip 2 of one of the closure elements according to the invention. The cover lip 2 is designed as a circumferential, obliquely arranged, flat flange 21 which runs around the cover base 2a and has a thickened area 23 which is limited in area. The lower surface section 24 of the thickening 23 is arranged parallel to the upper surface section 25 of the edge bead 18, which is triangular in cross section. The surface section 26 of the thickening 23 adjoining the lower surface section 24 on the cover lip side is arranged at an angle to the locking surface section 19 of the edge bead 18 such that when the cover 1, la, lb is closed, the cover lip 2 runs circumferentially on three edge bead side surface sections 27, which are spaced apart from one another. 28, 29 of the hollow body 30 are supported (FIG. 4c). This design of the cover profile 2 in conjunction with the edge bead 18 considerably simplifies the handling of the closure element, since the closure and the opening are simplified by the conicity of the surface section 25 and the locking surface section 19. Due to the three-point bearing of the fullest rim 18 on the cover lip 2 in the area of the surface sections 27, 28, 29, the hollow body 30 to be closed is also sealed well guaranteed.

So it can be advantageous to form 2 webs on the cover lip in order to achieve a special clamping effect against the hollow body to be closed. It is also possible to form the side walls 7 of the openings 6 in a cylindrical manner if the clamping plate 5 rests on outer elevations of the hollow body or can engage in recesses in the hollow body on the outer walls.

For externally smooth-walled hollow bodies 30, it is also possible to form tongue-shaped tabs on the clamping plate 5 by means of radially arranged slots which, when the clamping plate 5 is pushed onto the hollow body 30, can be brought elastically into contact with the outer wall of the hollow body 30 so that the clamping plate 5 can serve as an abutment.

5a and b show a further closure cover 1 which is functionally connected to a clamping plate 5a which can be pushed onto the hollow body 30. The clamping plate 5a has an annular blank 31 which can be pushed onto or inserted into the opening edge 34 of the hollow body 30, the cut 31 in each case sealingly resting against the hollow body 30. Stiffening segments 33 are preferably formed on the outer circumference of the blank 31 at equal distances from one another. On the sealing cover lc u are segment-like handles 32 on the catch side in such a manner that the bulges 18 are pressed into the recess 37 of the blank 31 when the Ran is pressed into the recess 37 of the blank 31 between the stiffening segments 33. This ensures simple one-hand operation for opening the closure lid 1c, since the operator's thumb 38 must be supported on a stiffening segment 33 serving as an abutment while the index finger 39 presses from below against a handle 32 which is adjacent to the aforementioned stiffening segment 33.

It is advantageous to crank the stiffening segments 33 vertically corresponding to the thickness 32a of the handles 32 with respect to the plane 35 of the blank 31. Thereby be¬ found in a closed hollow body 30 of the ^"stiffening segments 33 and handle 32 in a plane 36, wo¬ by the stackability of the sealed hollow body 30 is facilitated. It is also possible for the handle 32 and the stiffened ngssegment 33 respectively as to form a circular plate section in order to enable simple two-hand operation, particularly in the case of containers with large closable openings.
