Description

The invention relates to a container with an opening on the lid, one stuck over the opening Band, the end near the lid not one glued tab to pull off the tape forms. Derarti ge container, e.g. B. cans are for taking under Pressurized liquids, e.g. B. of carbon dioxide suitable drinks.

From US-PS 39 90 603 a container with a Opening on the lid, pointing to the outer surface of the lid around the opening and cover it a tape is glued on. On the inside surface of the Lid is around and around the opening fend a sheet applied through the opening by sticking to the tape. This container is as Pressure vessel z. B. for lemonade or beer bar. The tape and the sheet sticking to it can be pulled off the opening by hand so that you get to the contents of the container. With this container the user pulls the tape completely off the lid and often throws it out in an uncontrolled manner.

From an environmental point of view, is a Prevent users from getting the tape completely pulls it off the lid and it just goes somewhere throws. It has been shown to be necessary between egg a stronger one at the end of the band and the cover Use glue than for the rest of the tape. The Applying this stronger glue, however, will throw agreed on technical production problems and he increases the cost of the container.

Secondly, the band of the container must be elastic be enough to pull it off the opening does not protrude too far from the lid of the container and a user does not drink the contents of the container impaired.

The invention has for its object a Be to design containers of the type mentioned in such a way that the stated requirements are met.

According to the invention, this object is achieved by that the lid be made of a flexible sheet material stands in the opening a protruding towards the tab Genetic part remains on the lid, which is attached to the band kIbt is, and when removing the tape the Scherhaf tion between the tape and the bent over Genigen part a separation of the tape from the lid restricted.

Advantageous further developments of the invention ß container result from the claims 2 to 7.

The tape pulled off the lid becomes advantageous ternarily held close to the lid, so that there is a loading users are not bothered when drinking the contents of the container. The container according to the invention is also environmentally friendly fairer. That on the outer surface of the container around the Opening around and completely glued over this Ribbon, the end of which is un sticks and has a flap is easy of Hand graspable. The tape is pulled off the opening by pulling the tab over the band by hand becomes. The tongue-like part attached to the belt can be Bending back with the tape deforms permanently when pulling the tape from the opening and will held close to the lid, the shear adhesion between the band and the bent tongue-like Part of a separation of the tape from the lid.

In addition, the tongue-like part presumably supports Lich resistance to buckling of the tape over the opening due to the internal pressure in the loading container on which the lid is attached, and allows the Use an elongated opening, the one has a generally uniform width so that a liquid  gently drunk through the opening can be. Preferably the tongue-like sticks Part in bending to yourself, as a result its relatively large widened end part at the free end, which for a great adhesive force between the end part and the band. Furthermore is a part of a leaf initially over the opening inside the Lid stuck and sticks to the opposite Area of the tape through the opening. This Part separates along the incision of the opening and sticks to the tape so that the tongue-like part slipped in between them when the tape was removed remains. In addition, the between the end part free end and the part at the fixed end of the tongue-like part is preferably less Spread out as the end part at the free end, so that it extends can be easily bent with the tape.

Alternatively, however, the entire tongue-like Part must be sufficiently narrow so that it is easy to handle allows the band to bend, the end part at the free end of the tongue-like part on the belt over a stiff inlet ge between the sheet and the end part at the free end of the tongue-like part is attached. The tongue-like Part can also have a relatively large end part free end with uniform width over its length have, with parts of the tongue-like part between the end part at the free end and the fixed end are carried out with reduced thickness to the Umbie to facilitate gene.

Furthermore, the lid can preferably be one in the Have central ventilation opening that the Tape also covers and that when pulling the ban which is first opened to release gases from the liquid to let it escape without splashing it out.

Fig. 18 is a partial plan view of another embodiment of the lid of the container.

Figs. 1 to 7 show an embodiment of an end 10 of the container 15 having a lid 12 (Fig. 3) of flexible sheet material or metal which is easily reduced at high folding permanently deformed (as example 0.33 mm) tin free Stole). A circular flange 14 is attached to the end 10 of the cylindrical container 15 in a conventional manner. The Dek kel 12 has a generally U-shaped opening 16 and a constricted tongue-like part 18 which has a widened end part 22 at the free end and a part 20 of reduced width between this and its fixed end. The tongue-like portion 18 projects generally radially from the lid 12 between the sides of the opening 16 . A tape 24 is glued to the outer surface of the lid 12 around the opening 16 and fully covering it, whereby the end of the tape 24 is not glued and forms a tab 26 for pulling off the tape 24 .

Furthermore, a thin transparent sheet 34 made of polymer material is provided at the end of the container 10 , which is glued firmly onto the inner surface of the lid 12 around the opening 16 and completely covers it. Around the tongue-like part 18 , the sheet 34 is glued to the opposite band 24 and is separated when the band 24 is pulled off at the opening 16 . The sheet 34 on the inner surface of the lid 12 can serve to protect the edge of the opening 16 and the edge of the tongue-like part 18 from the contents of the container 15 , which is important if a coating of the lid 12 is interrupted in this area and the contents of the container could chemically react with the uncoated metal of the lid 12 .

Figs. 5 to 7 show the removal of the belt 24 from the position over the opening 16 when opening the can. The tab 26 is gripped and pulled over the glued part of the tape 24 to pull the tape 24 from the lid 12 , starting at the tape end at the base edge of the edge of the U-shaped opening 16 initiate. The sheet 34 is when pulling off the tape 24 at the edge of the opening 16 by separating and the sheet part adhering to the tape 24 and the tongue-like part 18 is removed when the tape 24 is removed. Extends the peeled part of the tape 24 to the widened end part 22 at the free end of the tongue-like part 18 , cause the adhesive glue on the tape 24 to the widened end part 22 of the tongue-like part 18 and the position of the end part 22 between the tape 24th and a part of the sheet 34 that the end portion 22 is adhered to the band 24 is lifted with this, while the part 20 of reduced width of the tongue-like part 18 bends with the band 24 when it is removed ( Fig. 6). The opening process is completed when the band 24 is pulled off to the fixed end of the tongue-like part 18 ( FIGS. 2 and 7). The entire tongue-like part 18 is then in wesent union from the opening 16 in a position in which it is permanently deformed into a position spaced from the cover 12 and holds a larger part of the pulled tape 24 , so that the tape 24 in the vertical direction protrudes only insignificantly to the outer surface of the lid. Since further tension on the tab 26 ensures a shear adhesion between the band 24 and the bent part 18 , the band 24 is not easily removable from the tongue-shaped part 18 and its separation from the cover 12 is thus restricted. In addition, the tab 26 is designed in such a strength that it tears force when pulling the tape before the occurrence of a train with which the tape 24 would be removed from the bent part 18 .

As shown in Fig. 1, the width of the constricted part 20 of the tongue-like part 18 preferably increases towards the fixed end. This makes it difficult to tear off the tongue-like part 18 from the cover 12 by repeated bending back and forth and thus to completely pull the tape 24 off the cover 12 . The opening 16 is preferably carried out at the transition to the tongue-like part 18 in the areas 30 with a sufficient radius such that loading areas of the stress concentration remain low, at which the cover 12 could tear as a result of the internal pressure. Also, the edges of the widened end portion 22 are preferably spaced from the adjacent edge of the opening 16 in order to limit the peeling effect which a lifting of the tongue-like part 18 as a result of the pressure in the can on the adjacent parts of the band 24 may have.

As is known, the opening 16 preferably additionally has a relatively narrow bogenförmi gene part 32 which protrudes toward the flange 14 of the cover 12 . The part 32 of the opening 16 is first exposed when the tape 24 is pulled off. Once this has been done, a small pressure equalization opening is created, which allows safe and relatively quiet pressure equalization from the inside of the container.

The part 45 ver reduced width of the tongue-like part 42 has, in this embodiment of the container, a uniform width between the widened end part 46 at the free end and the fixed end, so that the tongue-like part 42 can be bent more easily while the band 43 is being pulled off becomes.

Fig. 9 shows a further alternative embodiment of a container 49 with a lid 50 which has a general U-shaped opening 51 and a tongue-like part 52 which protrudes between the edges of the opening to the end near the lid edge. A band 53 , only a part of which is shown, is arranged on the outer surface of the cover 50 around the U-shaped opening 51 and covers it completely and can be removed from the cover 50 with its end near the end of the cover. On the inner surface of the lid 50 around the opening 51 and this completely bedek kend a sheet 54 is arranged, which is glued to the adjacent surface of the opening 51 on the adjacent surface of the tape 53 . The tongue-like part 52 has a relatively large widened end part 55 at the free end, which extends across the entire width between the lateral edges of the opening 51 . This supports the attachment of the tongue-like part 52 to the band 53 . The tongue-like part 52 also has between the end part 55 at the free end and its fixed end two narrow rectangular parts 56 along the side edges of the opening 51 . The parts 56 are sufficiently narrow in their overall width than the end part 55 , so that the tongue-like part 52 with the band 53 can bend while the band 53 is being pulled off. If this embodiment of the loading container for pressurized liquids is used, the cover 50 should have relief openings 57 at the ends of the opening 51 in order to avoid stress risings of the cover 50 due to the internal pressure.

FIGS. 10 and 11 show another alternative embodiment of the container 59 with a lid 60 having a generally U-shaped opening 61 and a tongue-like portion 62 which protrudes between the edges of the opening 61 to the edge of the lid proximal end. A tape 63 , of which only a part is shown in Fig. 10, is glued to the outer surface of the lid 60 around the opening 61 and completely covering this and can be removed from the lid 60 starting with its end near the edge. A thin sheet 64 is glued to the inner surface of the cover 60 around the opening 61 and completely covering it, parts of the sheet 64 around the tongue-like part 62 being stuck to the adjacent surface of the band 63 in the region of the opening 61 . The tongue-like part 62 has a uniform and sufficiently large width so that the adhesion between the tongue-like part 62 and the band 63 and the layer-like fastening of the tongue-like part 62 between the band 63 and the sheet 64 cause the tongue-like part when pulling the tape 63 is held on this. The thickness of the tongue-like part 62 is reduced in transverse regions 66 , which are spaced along its length, so that the tongue-like part 62 bends with the tape 63 when it is pulled off.

Figs. 12, 13 show another alternative exporting approximate shape of a container 69 with a lid 70 having a generally U-shaped opening 71 and a tongue like portion 72 which protrudes between the lateral edges of the opening 71 to the edge of the lid near-En de . A tape 73 , of which Fig. 12 shows only a part, is glued to the outer surface of the lid 70 around the opening 71 and completely covering it and can be removed from the lid 70 starting at the end of the lid. A sheet 74 is glued to the inner surface of the lid 70 around and completely covering the opening 71 , with parts of the sheet 74 around the tongue-like part 72 being glued to the adjacent surface of the band 73 through the opening 71 . The tongue-like part 72 has a uniform narrow width, which allows the tongue-like part 72 to be bent backwards with the band 73 over its entire length when the band 73 is pulled off. The container 69 has a rigid insert 76 made of polyester material between the edges of the opening 71 and the sheet 74 and the end part at the free end of the tongue-like part 72 , which due to the adhesion of the tape 73 to the insert 76 and the remaining of the insert 76 between the band 73 and the part of the sheet 74 remaining on the band 73 , when the band 73 is pulled off, defines the end part of the tongue-like part 72 on the band 73 , so that the tongue-like part 72 remains on the band 73 when it is removed.

Figs. 14 to 17 show a further alternative embodiment of a container 79 with a lid 80 having a generally U-shaped opening 81 and a constricted tongue-like portion 82 of the interim's lateral edges of the opening 81 in this front stands. A band 83 is on the outer surface of the lid 80 around the U-shaped opening 80 around and this is arranged completely covering and can be deducted from the lid. A sheet 84 is glued to the inner surface of the lid 80 around the opening 81 and fully covering it and glued with parts around the tongue-like part 82 to the adjacent surface of the tape 83 through the opening 81 in the angle 80 through it.

The container 79 has a ventilation hole 85 centered in the cover 80 . The sheet 84 and the tape 83 are adhered to the opposite sides of the vent hole 85 and together through the vent hole 85 through the adhesive layer 86 , the tape 83 being configured to be peeled first from the vent hole 85 and then from the opening 81 . In this way the pressure in the container 79 , e.g. B. a can, relaxed in the middle of the lid 80 so that the gas emerging from the can does not inject liquid through the ventilation hole 85 .

As best seen in FIGS. 16 and 17, the band 83 has an inner part 87 which is glued to the outer surface of the cover 80 around the opening 81 and covers it completely and along an edge 96 on the circumference of the cover 80 is led. Furthermore, an outer part 88 is glued to the inner part 87 along the edge 96 . The outer part 88 lies over the inner part 87 , is glued over the ventilation hole 85 and ends in a tangible tab 97 , by means of which the band 83 can be pulled off.

As is apparent from FIGS. 14, 16, 18, the outer part is first pulled off of the tape 83, 88 vent hole 85, wherein the adhesive on the outer portion 88 of the blade part 84 tear out (Fig. 16). Thereafter, the inner portion 87 of the band 83 with the tongue-like part 82 ( Fig. 17) is withdrawn to open the container 79 and to hold the band 83 on the lid 80 in a position in which it is from the face of the person who drinks the container 79 through the opening 81 , is kept away.
