Description

Patent Descriptive Report for "DECHAPA COVER WITH GUIDE COLUMNS FOR A CONTAINER".

The present invention relates to a container lid having a sealing edge region - preferably watertight and permanent - with the container body consisting of hull wall and bottom. Such containers exist for multiple purposes, for example for filling with food or beverages. The closure lids may therefore have detachable regions provided with gripping details for the irreversible release of a withdrawal opening, as is known above all from beverage cans. Therefore, the invention also relates to plate closures for the closure of beverage can bodies.

It is an object of the invention to develop a lid for a container body which, in the manufacture of the lid, is provided with the means for arranging one or more additional elements in the lid that can be moved linearly relative to the lid in a predetermined direction perpendicular to the axis of the container. cover. These additional elements are not themselves objects of the invention. Only as an element will an element be mentioned for securing the reclosing of a free lid opening.

This objective is achieved in accordance with claim 1. Its manufacture presents the cap according to the invention in the essentially flat region (such as central flat area, panel or lid surface), which is encircled by the edge region - serving for union with the recipient body - at least one or several guiding elements. These are pin or column type guide elements aligned essentially with their axis approximately parallel to the lid axis extending perpendicular to the lid surface (claim 2).

As already emphasized, in such guide elements a device such as a sealing member may be guided linearly with respect to the surface of the lid and approximately in the direction of the shaft (lid axis) (claim 28). The guide element as a member emphasizes such a height and execution that it is suitable for guide, so allow a course or a displacement towards the height pointing away from the surface region. They are not pre-stamped rivets of the die plate or protrusions, in which for example a SOT splint is permanently mounted and possibly rotatable. These mounting rivets have no guide property and no such geometric execution.

In an opening cap limited by an opening edge, the at least one element is disposed outside the opening (claim 2).

The guide elements, depending on the purpose of use, may extend from the upper side of the lid and / or the lower side of the lid, preferably into the container body.

Other advantageous configurations of the new cap will be understood from dependent claims.

The edge region (or also body) surrounds the central surface region. It is suitable to be fixed to the container body by a folding joint. This body can be made in one piece, therefore with a bottom arranged directly without bending in the body wall, which is called "body". The body itself, however, is not the object of independent claims (claim 1, 2, 23 as well as 28). The watertight and permanent joint corresponds to the bend seam, whether resulting from an edge or folding of the datamp edge region at the correspondingly adjusted body edge, therefore at the upper end of the body as the body edge. Both edges are so adjusted to each other that the folding seam reaches the watertight and permanent union of the lid for closing the container body.

An occasional closing function and an opening function by re-closing an additional element can be carried out in a controlled and guided manner by means of the guide elements which are associated with the lid plate.

As for the position of the guide elements, it must be said that they cannot lie or be in the free opening and are provided outside this relatively large opening. To this end, there is an intermediate region that lies between the edge region, as just described as the fold edge, and the outer edge of the free opening. In this intermediate region is provided at least one guide element of the type pin or column. It projects to one side or the other, preferably into the body of the container and thereby to that side which defines the edge region of the lid in detail which can be joined with the body edge by means of they rest on the edge of the body. Due to the execution of the edge region, it is generally a channel-type curvature region. In this way the bend region can the technician identify which side of the lid is assigned to the container and the same side points outwards.

The guide member preferably has an essentially constant thickness. This thickness extends over the length of the guide element (claim 3). A preferred height is above 5mm (claim 4). Throughout this height the transverse section of at least one guide element may remain constant.

The arrangement of at least one guide element near the opening edge should be understood in such a way that it is near the opening (claim 5). The guide element is thus clearly closer to the opening edge than to the joining edge region. In other words, the guide elements in the intermediate region are essentially shifted more inward than outward. They stand on the edge of the "open" (claim 21).

By employing several guide elements, for example two mutually opposite, extending to the same side (claim 6, claim 28), an especially precise parallel guide can be obtained. The element guided for secure re-closure cannot then be swung but is held in its essentially parallel position and guided reliably in a direction perpendicular to the plane of the central surface region by a lifting and settling motion.

A slight inclination of the guide elements should not be excluded (claim 7). This inclination is oriented closer to 90 ° so above 75 ° and below 90 ° with the latter being the parallelel alignment to an axis perpendicular to the central region (claim 2). The execution of the at least one guide element may be of sheet metal or plastic (claims 8, 9 and 10).

The lid may be produced together with the guide elements (claim 11). This joint production as a unit is preferably done in the injection molding technique. Such injection molding technique is representative for a pressure molding, with which the guide elements may be shaped (claim 23) or may be shaped (claim 12).

In order to obtain retention on the lid surface, a cohesive plastic layer is employed, which carries one or more guide elements, respectively made in one piece with these guide elements. Joining the plastic layer with the lid surface (the central region as a panel) provides retention of the guide elements in the metal lid plate. Such retention may be by a rolling strip around the opening (claim 13). It can then be performed unilaterally or bilaterally, and an U-profile can result (claim 23, 24). Application of the profiled layer (claim 25) provides reliable positioning and alignment of the guide elements. The layer and with it the guide elements can then no longer be separated without destroying the lid. It is evident that a layer of plastic with guide elements resulting from injection molding or pressure molding is made in one piece (claim 26).

The opening is performed relatively large (claim 27).

The engagement around the edge and inside is thus made in a comparatively large radius in a circular perforation (claim 27).

The one-piece arrangement may also be expressed as "material locking" (claim 31).

When various terms are used for the guide elements, such as bar, pin, or column, this should respectively express that at least one guide element is appropriate to allow a guided upward movement, which is not just an indication of employment. but rather an expression of the technical function and, thus, a functional definition of such structurally executed guide elements, which allow this displacement in height direction, and such "retaining elements", which do not allow exactly this displacement with respect to to the lid plate (claim 28, 29).

The current state of the art does not, on the contrary, present any indications of the claimed invention. DE-U 202 19 794 (Blechwarenfa-brik Limburg) illustrates a stackable container with an edge region 5 for tight and permanent union with the container body consisting of body 2 and bottom 4 (references are taken from that publication). An essentially flat central region (3a) is provided, wherein an opening is envisaged limited by an opening region for the filling of the filler (the opening is designated 17).

In the region between edge and aperture is arranged at least one element, such as a handle (therein 18 and figure 3) is retained on the lid surface. Such loop elements are only seen therein in Figure 3 and not further described; In any case, loop 18 is explained as present, cf. there on page 10, last paragraph, and this handle is disposed at a considerable distance from the opening there on the surface of the lid (the so-called upper bottom). The essential design of this publication refers to the easier or improved possibility of wall labeling and proposes to restrict the cross section to a short upper region and a short lower region, and to maintain the cross section of the wall unchanged. re-recipient, cf. there page 8, first paragraph. Also deformations on the surface of the lid refer to DE-U 19 34 945, which are shown there in Figure 2 in top view and in sectional view of Figure 1. These are performed as curved or arched grooves extending through the corners. essentially arc-shaped and staggered. The purpose is to reinforce the surface of the lid. CH-C 494 165 refers to similar reinforcements. Elsewhere, outside the surface of the lid according to EP-A 1,361,164 or the corresponding WO-A 03/089 167, a change in the circulating damping channel is provided which is altered by its width or position. Again diverging from the damping groove in US-A 2,822,952, column 1, lines 53 to 70, there is aimed at a better can stacking capability for which a corrugated lid surface configuration is employed, cf. Figure 4. A comparable but extending triangular cross-sectional structure is known from US-A 3,070,257, also for container stacking or for improved stackability. From GB-A 518,778 a metal container has been known since the 1930s, in which the possibility of withdrawal should be improved, cf. there page 1, left column, center paragraph; an opening therein 4 is provided and around a recess in the lid surface a channel is formed which flows into the said opening. A usual handle or handle is designated therewith and also disposed on the lid plate, cf. there page 2, right column, third paragraph.

Advantageous configurations of the claim cover and corresponding processes follow from the descriptions of the examples.

The invention will be described in more detail below with help of schematic drawings by way of examples.

Figure 1 is an axially sealed container, closed with a lid, which is manufactured according to an example of the invention.

Figure 2 - the lid according to figure 1 in larger scale and seen from the top with a free opening in the panel.

Figure 3 - the lid according to figure 2 in cross section.

Figure 4a - Cut-out and top view of a filler and / or withdrawal opening surface prior to deformation of the guide elements.

Figure 4b - in perspective representation, the lid cutout according to figure 4a after deformation of the guide elements.

Figure 5a, Figure 5b, Figure 5c - in perspective view, three guide elements with various examples of their cross-sectional shape. Figure 6 - in clipping and cross section, other ways of performing a cover with guide elements.

Figure 1 shows a typical container body 4 ("body"), as is customary for example from deep drawing plate or drawing, for drinks. It comprises a cylindrical body wall 5 with longitudinal axis 9 and a bottom 6 joined in one piece with the body wall. With the container body 4 is joined a lid made or produced according to various examples of the invention by a sealed and permanent seam made by the body edge or lid edge 2, which is performed as bend 2a. Between the fold 2a and the panel 3 is a flat area an anti-peaking bead.

Lid 1 has a "lid surface" (such as the central flat region panel 3) which is essentially flat and is joined by lid edge 2 via a cushioning groove 2b (with the "chuckwall"). The lid panel has, in the illustrated example, three guide elements 7 ', 7 "and 8. The two guide elements 7 extend parallel upwards, while the guide element 8 extends from the panel 3 to All three guide elements are arranged parallel to each other and parallel to the axis 9 of the lid 1. They are bar, column or pin shaped and may extend for a length of between 5 mm and 15 mm.

One or two of these guide elements, for example the two pins 7 ', 7 ", also directed inwards, I need.

In the example of Figures 1 to 3, the cross section of the guide elements is approximately circular round. As indicated in FIGS. 5 in examples 31, 32 and 33, the cross section may also be completely different. The shape of the cross-section depends on the purpose of employment, thus on the type of device to be guided on the guide elements, which is not itself an object of the invention.

The cross-section is constant by the (guide) length of the two guide elements 7 ', 7 "or T and 8. The axis of each guide element forms the angle of the lid surface with an angle α (alpha) between 75 DEferential 80 0 and 90 being therefore in the limiting case the angle φ = 90 0 (pi is 90 °) essentially parallel to the axis 9 of the lid.

The at least one guide element may also be aligned less than 90 ° with respect to the plane of the lid surface, for example between 75 ° and below 90 ° as indicated symbolically by the angle α in figure 3. Corresponding to this angular alignment, the element 8 or also the guide element 7 "is aligned at an angle below 90. This applies to a parallel alignment of the guide elements T and 7" also to the previously mentioned T element. The guide elements respectively represent longitudinal axes, which no longer extend parallel to the longitudinal axis 9. The longitudinal axis9 was hitherto treated as the container axis, but is also a congruent longitudinal axis with respect to the lid, as shown in figure 2 in the center point of the cover panel 3.

The lid shown in figures 2 and 3 is manufactured with a filling and / or removal opening 11 limited by an opening edge 10, which is disposed off-center on the lid surface 3. The two outer guide members 7 ', 7 " they are arranged close to the opening edge 10 and are diametrically opposed to each other, their distance from the opening edge 10 advantageously matters from 0 to 5 mm, however they are situated between opening 11 and lip 2. The guide element 8 on the lower side is positioned in this case in alignment with the guide element 7 "on the outside. The aperture is relatively large. In an example not shown, the guide elements 7 ', 7 "protrude downwards / inwards, 8 becomes 7" and 7 "diametrically opposed.

The guide elements may be produced or molded in various ways when manufacturing the lid.

Figures 4a and 4b show in the example of a plate cover molding of the guide elements by flexing the datamp plate. For this purpose, in the example shown, when the opening 16 limited by the opening edge 17 in the lid panel 15 is produced, two opposing plate lobes 18 ', 18' are left. 17, 19 ", 19" notches bilaterally, leaving a bridging region 20. There the lobes are bent approximately 90 ° to the lid surface (bending point 20a) and wound to a respective cylinder 18a.

Also the guide elements may be produced or in-depth or similar embedment directly from the lid material.

For the production of the guide elements pressure techniques may also be employed, for example injection molding techniques within the scope of the lid manufacture. Thus, the guide elements may be applied to the lid surface material by employing a mass of plastic by applying pressure and high temperature together with a cohesive plastic layer by "pressure molding." Caps and guide elements may also be molded as a unit of a non-metallic material.

As an example for one of these "pressing" techniques, in Fig. 6 - in section and cut out of a metal lid panel 40 - a cohesive plastic layer 43 along the edge 42 of opening 41 in panel 40 when The fabrication of the lid was applied by pressure molding, which in the example shown also at least partly engages around the opening edge 42 (at 43a) and is arranged in one piece, with at least one guide element, preferably both elements. 43b ', 43b ".

As indicated by the dashed line in Figure 6, there may also be a U-shaped cut-away engagement of the opening edge, so that as the U-shaped layer 43a, 43c a permanent application of the rods is obtained. 43b 'and 43b "on the edge of the opening, which cannot be separated without destroying the lid. This manufacturing process applies pressure and plastic to the U-profile 43a, 43c at the opening edge 42 and thereby the bars, pins or columns 43b ', 43b "as guide elements (for axially guided movement) in the cover plate. The outwardly facing side 43c is indicated only as dashed as an option in Figure 6. The bars / columns preferably protrude into the housing compartment. Correspondingly, also the shapes of figures 5 or pins 7 ', 7 "or 8" are arranged "near the edge" 10 (near that edge).

The entire surface of the lid with the guide members may also be molded of plastic and be securely joined by pressure molding with an annular metal part, with the biasing edge in the manner described above.

The lid can be easily modified with high precision without great expense for any corresponding application purpose. It is preferred for the beverage can closure region, which covers its panel, its size (below a diameter of 60 mm) and its bend 2 suitable for folding. Also the thin plate thickness.
