Abstract
Description
- The present invention relates to a receptacle with a pour spout and a screw cap of plastic, with a guarantee strip which is arranged at the lower edge of the peripheral lateral wall of the screw cap, which is held secured at least in the axial direction on the pour spout of a receptacle in a direct or indirect manner.
- Receptacles with a pour spout and a screw cap of plastic, which may be placed thereon, are known in many design forms. Thereby, the receptacles may be glass or plastic bottles, or soft packages of laminates or of plastic films. If the receptacles are glass or plastic bottles, then the bottle neck typically forms the pour spout. If the receptacle is a tube, then the tube opening of the tube head often forms the pour spout. In any case however, the pour spout comprises an outer thread, on which correspondingly a screw cap with an inner thread integrally formed on its lateral wall may be screwed.
- Nowadays, screw caps are usually provided with a guarantee strip. For ecological reasons, the guarantee strip is designed such that after separation from the pour spout or from the screw cap, it respectively either remains on the pour spout or on the screw cap. In one case, the guarantee strip is held on the pour spout with a positive fit, by way of the guarantee strip forming a retaining ring, which by way of a suitable positive-fit means between the retaining ring and the pour spout, is held on the latter. This guarantee strip, or retaining ring as the case may be, may be rotated relative to the pour spout, or the positive-fit means may be designed such that a rotational securing is simultaneously realized. On opening for the first time, the break-away tabs between the retaining ring, or the guarantee strip, and the screw cap are broken. If the strip can co-rotate, then the break-away tabs are loaded in tension in the axial direction, so that the break-away tabs have a greater tear resistance. If the guarantee strip or the securing ring is also secured in the radial movement direction, then the break-away tabs are loaded in shearing on opening for the first time, and accordingly may be severed with a low force effort.
- The guarantee strip is usually arranged on the lower edge flush against the lateral wall, or in another known embodiment, is formed of different part sections which are connected to one another via radially running break-away tabs. On opening for the first time, a widening of the guarantee strip is effected, wherein the break-away tabs sever, and the sections of the guarantee strip remain on the cap.
- It is more often than not that the screw caps are relatively small, and the danger exists that such screw caps get lost or fall on the ground and become contaminated. Since in many cases, these screw caps are then reattached to receptacles in which foodstuffs are accommodated, accordingly the danger exists that the contents are contaminated.
- It is therefore the object of the present invention, to provide a receptacle with a pour spout and a screw cap of plastic, with which a guarantee strip visibly displays the integrity guarantee, and simultaneously the screwed-off screw cap remains captively connected to the receptacle, or its pour spout.
- It is a further object of the invention to specify alternative connection possibilities between the retaining ring and the pour spout, which are suitable for different receptacles. A preferred embodiment of the subject-matter of the invention is represented in the drawing, and is explained in detail by way of the subsequent description.
- Other features and advantages of the invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, the features of the invention.
- A preferred embodiment of the subject-matter of the invention is represented in the drawing, and is explained in detail by way of the subsequent description. There are shown in:

FIG. 8 is an enlarged cross sectional view of the screw cap ofFIG. 1 in its sealed position on a bottle-like receptacle; and -
FIG. 9 is a cross sectional view of the screw cap in the non-assembled condition, in the integrity position. -
FIG. 7 illustrates a first preferred embodiment of the present invention configured to a receptacle 1 having apour spout 2 and ascrew cap 3 that may be screwed thereon and is captively connected to thepour spout 5 via asafety tether 4 which here also serves as a securing strip, by way of aretaining ring 5. - The invention may be realized independently of the type and design of the receptacle 1. Thus the receptacle 1, as shown here, consists of a soft packaging of plastic film or of a combined plastic-cardboard laminate, or may also be realized as a glass bottle or plastic bottle. In any case however, the receptacle 1 is provided with a
pour spout 2. Thispour spout 2 may be also realized as part of the bottle neck with glass or plastic bottles. - With soft packages such as represented here in
FIGS. 6 and 7 , the pour spout is a separate component, consisting of a cylindrical tube section on which aperipheral flange 22 is integrally formed at the lower end. Here, the screw cap according to the invention is represented in the opened condition. Theflange 22, depending on whether it is welded onto the soft packaging 1 from the inside of the packaging or from the outside, may be provided withwelding ribs 23 on the upper side or on the lower side as is shown inFIG. 6 . Of course, thecylindrical tube section 21 of thepour spout 2 is provided with anouter thread 24. Thescrew cap 3 is completely unscrewed from thepour spout 2, but is connected to thepour spout 2 via thesafety tether 4, which in this case only continues to have the function as a securing strip. Aretaining ring 5 is provided for this connection. The type of the connection of theretaining ring 5 to thepour spout 2 may be realized in various manners, but this is not evident inFIG. 6 . These connection possibilities are dealt with later in a more detailed manner. - In
FIG. 1 , thescrew cap 3 is placed onto a spout in the integrity position. Thescrew cap 3 has alateral wall 31 and is closed at the top by acover surface 32. Thescrew cap 3 is provided on the outer side of thelateral wall 31 with a ribbing 33 increasing the grip. An inner thread is incorporated on the inner side of the lateral wall 31 (not shown). On the lower side, aperipheral collar 34 is integrally formed on thelateral wall 31. Theretaining ring 5 is connected to thepour spout 2 in a rotatable but axial secured manner, and lies directly above theflange 22. Thesecurity tether 4 is arranged between theretaining ring 5 and thecollar 34 if present. Thesecurity tether 4 in this position only has the function of an integrity guarantee, i.e., demonstrates that the contents of the reservoir has not been tampered with through this opening since it was placed on by the manufacturer. The outer surface 41 of thesecurity tether 4 is flush with theouter surface 51 of theretaining ring 5, and likewise lies flush below the outer surface of theperipheral collar 34. In this guarantee position, all break-away tabs are intact. The break-away tabs in this position are barely evident. For this reason, the detail ofFIG. 5 is referred to, with which a cut-out is represented in a larger scale, wherein the break-away tabs here however are already shown in the destroyed condition. With the screw cap according to the invention, first break-away tabs 35 are present, which in the intact condition form the connection between theretaining ring 5 and thesecurity tether 4. Two break-away tabs form the connection between twoadjacent windings 42 of thesecurity tether 4. Finally, only the third break-away tabs 37 continue to be present, which form the connection between anuppermost winding 42 and thecollar 34, or the lower edge of thelateral wall 31 of the screw cap. In the position, as shown inFIG. 1 , which represents the guarantee position before opening for the first time, all break-away tabs FIGS. 2 , 3 and 4 are then effected. With a first screwing off movement, the break-awaytabs 35 are severed. Aconnection location 38 between thesecurity tether 4 and the retainingring 5 however remains intact. - With a continued unscrewing of the screw cap, as is shown in
FIG. 3 , the break-awaytabs 36 which are arranged between twoadjacent windings 42, are severed. Finally, as shown in theFIGS. 4 and 5 , also the break-awaytabs 37 between the uppermost winding 42 of thesecurity tether 4 and thecollar 34 or the lower edge of thelateral wall 31 are broken. Thescrew cap 3 may now be completely released, and removed from the pour spout. With this, the connection of thescrew cap 3 to the retainingring 5 however remains. Accordingly, asection connection location 39 is present, which represents the indestructible connection of thesecurity tether 4 to thescrew cap 3. - It is not significant with regard to the sequence in which the break-away
tabs security tether 4 first acts as an integrity guarantee element and thereafter as a securing means, is not changed by the sequence of the destruction of the break-away tabs. Although the sequence of the rupture of the first to third break off tabs is not significant, as has been explained above, this sequence may be influenced by certain measures. Thus the break-away tabs in the most obvious version may be designed differently in their cross section at the thinnest location, wherein for example the first break-awaytabs 35 would have the smallest cross section, whilst the second break-away tabs would have a slightly larger cross section, and the third break-away tabs could again have a larger cross section. This solution may be realized most simply with regard to manufacturing technology. - A second, somewhat more complex solution, lies in designing the first break-away tabs running inclined relative to the rotation axis of the
screw cap 3, or to the longitudinal axis of the pour-spout 2. By way of this design of the first break-awaytabs 35, a shear-off force occurs with the forces running in the axial direction, which realizes an easy destruction of the first break-awaytabs 35. With the second break-awaytabs 36, one may then form the inclination of these break-away tabs with regard to the deviation from the axial direction to a lesser extent, so that here the shear forces are not so large and thus tear later than the first break-awaytabs 35. Finally, the third break-awaytabs 37 may be arranged running exactly in the axial direction, so that the shear-off forces practically do not exist by way of this, and thus these break-awaytabs 37 tear last of all. With the sequence of destruction of the first to third break-away tabs described here, the first opening of the screw cap is effected in an aesthetically satisfactory manner, and it is ensured than no kinking of the guarantee strip occurs on opening for the first time. Such a kinking not only leads to the possible compromise of thesecurity tether 4, but may also render the screwing away of screw cap briefly more difficult. - The screw cap may again be returned onto the
spout 2 without any problem after the opening for the first time. With this, it is however impossible to wind on thesecurity tether 4 around the pourspout 2 such that the security tether again assumes the position according toFIG. 1 . This is prevented alone on account of the restoring force of the security tether being low, and secondly because the tensile forces occurring on opening for the first time effect a certain plastic deformation, so that the security tether tends to unwind. Even if one firmly holds the retainingring 5 during the rescrewing-operation until thescrew cap 3 is completely screwed on and thesecurity tether 4 has assumed practically the same position as inFIG. 4 , then thetether 4 again tends to relax and accordingly the retainingring 5 and the security tether always evidently rotates away from the pourspout 2, so that its destruction is obvious. - With a solution with which the pour
spout 2 is provided with aflange 22, it is also possible to screw the retainingring 5 to theflange 22. In this case, the plastic deformation forces which occur on the security tether on opening for the first time, are significantly larger and accordingly thesecurity tether 4 may also not be brought back into the shape as is shown inFIG. 1 . - In
FIG. 8 , a part of abottle neck 2′ is represented in a larger scale, which for example may be manufactured of glass. Thebottle neck 2′ which thus forms the pourspout 2 comprises a peripheral retainingbead 25 which has a saw-tooth-shaped cross section, and forms a positive-fit connection means which cooperates with a connection means on the securingring 5. In the example shown here, the retainingring 5 on its surface directed towards the pour spout, is provided with a peripheralannular groove 51. Thisannular groove 51 may have a rectangular cross section or roughly an equal and opposite shape to the retainingbead 25. In the shown example, the retainingbead 25 has a saw-tooth-shaped cross-sectional shape. This permits the screw cap to be placed on with a low force effort. The occurring tensile forces are however accommodated fully by the part surfaces running perpendicular to the tensile direction. - Finally, a
screw cap 3 according to the invention is shown in an axial longitudinal section inFIG. 9 . Thelateral wall 31 is terminated by acover surface 32. Thecollar 34 is formed at the lower edge of thelateral wall 31. Theinner thread 38 mates with an external thread on the spout to secure thecap 3. This thread is preferably designed relatively steep, in order to achieve a rapid and secure severing of the break-awaytabs 35 to 37. The position represented here again corresponds to the integrity position in which thesecurity tether 4 is connected to itswindings 42 amongst one another, and to thecollar 34 as well as the retainingring 5 via the break-away tabs. The retainingring 5 here, on its inner side, comprises retainingbead sections 52 as positive fit means, which in the assembled condition are engaged in a corresponding annular retaining groove on the pourspout 2. These retainingbead sections 52 provide for a greater flexibility of the retainingring 5 than a peripheral continuous retaining bead, with which in turn it is ensured that no destruction occurs on placing on the screw cap. - In order to ensure that the break-away tabs are not destroyed when placing on the screw cap,
support elements 43 may be integrally formed on thesecurity tether 4, which ensure that with the compression experienced during tightening of the cap, the break-away tabs are not completely compressed together which could result in inadvertent destruction of the break-away tabs. Thesupport elements 43 can be arranged about the periphery, and in each case arranged offset with respect to the break-awaytabs 35 to 37.
