Description

DESCRIPTION

Closing of container

Field of invention

The invention relates to a container closure for closing a container, according to the preamble of claim 1, as well as to a container with such a container closure, according to the preamble of claim 14.

State of the art

In the field of plastic closure caps with a sealing ring, closure caps are known from the prior art, which remain on the container without getting lost and close its pouring opening. Closure caps of this type are also known, which have two retaining bands, which connect a threaded part of the closure cap with a sealing ring of the closure cap. The two retaining bands can function as a hinge, around which the threaded part of the sealing ring or the container to be closed is folded outwards.

Such a closure cap is known from EP 2308772 A1. The retaining strips are C-shaped and have a weakening at their centre of curvature in each case, at which the retaining strip can bend. As a result, the retaining strips interact as a hinge for the screw part. A protruding part is formed at the open edge of the screw part, which projects downwards. In the open position of the screw part, the protruding part comes into contact with the retaining ring of the container neck, which retaining ring holds the securing ring on the container neck. The protruding part holds the screw part in an open position and prevents the screw part from being disturbed when shaking a product contained in the container. However, when drinking from the bottle on which the closure cap is attached, the screw part is an obstacle, as it hinders the user.

In US 2018/0370701 A1 a closure cap is disclosed which also has two retaining strips. However, the ends of the retaining strips are alternately connected to the sealing ring and the open edge of the threaded part, i.e. the ends of the retaining strips which are connected to the open edge of the threaded part and to the sealing ring alternate. This gives the threaded part a certain stability when it is held in the open position on the bottle neck. The upper part or the cylindrical side wall of the threaded part can rest against the bottle neck. With this solution of a non-losing closure cap, there are a plurality of open positions for the threaded part. Therefore, without instructions, the user does not recognize which of the possible open positions he should move the threaded part to in order to be able to pour the filling product from the bottle through the threaded part with the least possible hindrance.

In JP 2012 076771 A a container with a screw cap according to the preamble of claim 1 is described, which is held in place by two retaining bands on a securing ring and thus indirectly also on the container after unscrewing. A tab is formed on the open edge of the screw cap between the two retaining bands. The tab enables the screw cap to be held in a defined open position on the container. In this way, the pouring of liquid from the container through the screw cap is not disturbed.

In WO 2022/077162 A1 a screw cap similar to that in JP 2012 076771 A is disclosed. In this prior art, too, a tab is formed between the two retaining bands. However, the position of the ends of the retaining bands is different.

Object of the invention

It is therefore the object of the present invention to propose a container closure which does not present the above disadvantages, i.e. which allows the user to intuitively select an opening position, in which the screw portion does not interfere with the use of the bottle and in which any residue of filling product present on the screw portion does not contaminate the shoulder of the bottle.

Description

The solution of the presented objective is achieved with a container closure for closing a container thanks to the characteristics mentioned in the distinctive paragraph of claim 1. Advantageous improvements and/or variants of the invention are the subject of the dependent claims.

The invention is characterized in that the first, second, third and fourth ends are arranged consecutively in the circumferential direction on the free edge or on the sealing ring and that the length of the first or second retaining band corresponds to between 27% and 32% and preferably between 29% and 30% of the outer diameter of the screw cap. The consecutive arrangement of the first, second, third and fourth ends and the precisely matched length of the retaining bands surprisingly allow the screw cap to automatically rotate with its inner side upwards and to spring back towards the support ring when it is unscrewed and pushed away from the bottle neck. With its free edge, the screw cap can be secured under the support ring at the corner formed by the bottle neck and the support ring. The engagement under the support ring is intuitive for the user of the container closure. In addition, the inner side of the cap is oriented upwards in the open position. As a result, any adhering filling product residue remains on the screw cap and cannot contaminate the outside of the container.

It is therefore preferred if the lengths of the first and second retaining bands allow the screw cap to be hooked with its free edge in the open position to the underside of a support ring formed below the container neck. In addition, the retaining bands have a hinge function, by which the screw cap is oriented with the inner side upwards after unscrewing and is positioned below the support ring. The open position therefore occurs automatically and no instructions are required for the correct use of the container closure. Preferably, the first and second retaining bands have the same length.

In a preferred embodiment of the invention, a first or second fold is provided on the first or second retaining band at the second and fourth ends. These folds allow the retaining bands to rotate outwards, which improves their articulation function.

Advantageously, a first and second recess is provided on the edge of the retaining ring facing the first and second retaining strips for receiving the first and second retaining strips. In this way, the first and second retaining strips are small in size and can be plied without additional material consumption of the retaining ring. For example, the first and second retaining strips can be cut from the retaining ring or shaped during the production process of the closure cap. In addition, the height of the retaining ring is not increased by the provision of the retaining strips and no additional material expenditure is required.

An extension of the securing ring is conveniently formed between the second end and the second recess. The extension keeps the securing ring sufficiently stable, even though the first and second recesses are provided in it.

In another preferred embodiment of the invention, a third recess is provided in the securing ring between the second end and the second recess. The third recess is preferably V-shaped and improves the hinge function of the first retaining band.

In another preferred embodiment of the invention, the second and fourth ends include an opening angle of at least 60 degrees and at most 90 degrees and preferably at least 70 and at most 80 degrees relative to the central point of the screw cap as apex. As a result, the first and second retaining bands have a distance from each other, which enables the functions described above in conjunction with the retaining band lengths.

It is preferable that the predetermined breaking ribs are arranged at regular intervals along the free edge. This way, the sealing ring remains sufficiently stable on the screw cap so that the container closure can be snapped onto the container neck. The screw cap can be unscrewed at the regular intervals of the predetermined breaking ribs and with a constant force.

It is advisable that the closure disc be fitted with an inwardly projecting inner cone, e.g. in the form of a sealing cylinder or a sealing ring, which is designed to cooperate hermetically with the inner wall of the neck of the container in the closed position. The closure cap can thus act as a so-called “sealing cone” and effectively seal the neck of the bottle. The sealing can also be achieved by means of a “jacket”.

In another preferred embodiment of the invention, the first and second retaining bands have a width of between 1.5 mm and 2.5 mm, and preferably a width of between 1.8 mm and 2.2 mm. This dimensioning ensures that the retaining band does not tear accidentally, in particular when the predetermined breaking ribs are torn. In addition, the securing ring is not very high and can be tightly coupled to standard container necks with external thread. It is preferable for the retaining bands to have a cross-sectional area of 1 mm2.

The invention is characterised in that the closure cap is designed to cooperate with a standard container neck with external thread and retaining ring. The closure cap can therefore be placed on standard container necks, in particular PET beverage bottles. For this reason, containers which are coupled with the closure cap according to the invention do not have to be specially adapted to the closure cap.

The closing cap is conveniently made of a plastic material, preferably HDPE (high-density polyethylene) or PP (polypropylene). The closing cap can therefore be made of standard plastic materials, from which well-known sealing caps with sealing rings are also produced.

In another preferred embodiment of the invention, the screw cap, the sealing ring, the retaining bands and the predetermined breaking ribs are produced in one piece. In this way, the container closure can be produced in an injection mould without any additional processing steps being necessary to mould the first and second retaining bands. Preferably, the inner cone is also produced in one piece together with the other parts of the container closure.

Machining steps would be necessary to form the first and second retaining bands. Preferably, the inner cone is also produced in one piece together with the other parts of the container closure.

In a particularly preferred embodiment of the invention, the retaining ring has grooves arranged around the circumference with an upper edge and a lower edge, the upper edge being formed by a circumferential retaining ring section in the form of a circular arc and the lower edge being formed by a wall section inclined in a radially inward direction, and the lower edge of each groove forming the projections with which coupling means for a form-fitting coupling with the retaining ring are formed. Since the coupling means in the form of the inwardly inclined wall sections are not present in their entirety in the retaining ring and, in addition, grooves are present, the molding of which further reduces the use of material, the need for plastic material can be significantly reduced by up to 5%. In addition, the wall section is immovable in a radially inward direction, so that the retaining ring is held in the retaining ring and can only be pulled over it once the retaining ring has extended along its circumference. The retaining ring is held so firmly in the retaining ring by the wall sections that the predetermined fracture ribs are sure to tear off before the retention of the wall sections is defeated. However, the wall sections are flexible and movable in a radially outward direction. In this way, the wall sections can be removed from the injection mould or injection moulding tool with little effort. For this reason, the force required to snap the closure cap into place is considerably reduced compared to the prior art. An extension of the retaining ring that could lead to permanent damage to the container closure is largely avoided by snapping it in.

In another preferred embodiment, a projection is formed below the first and second recesses. This ensures that the sealing ring is securely attached to the retaining ring in the area of the retaining strips and the tabs. This is particularly important when the screw cap is unscrewed and turned into the open position.

Another aspect of the invention relates to a container having a container body, a container neck connecting to the container body, an external thread formed on the container neck and a support ring formed at the transition from the container neck to the container body, wherein the first, second, third and fourth ends are arranged consecutively in the circumferential direction at the free edge or at the securing ring and the length of the first or second retaining band corresponds to between 28% and 32%, and preferably between 29% and 31% of the outer diameter of the supporting ring. This length dimensioning of the first and second retaining bands allows the free end of the screw cap to be hooked to the underside of the supporting ring.

In a preferred embodiment of the invention, the free edge of the screw cap is hooked to the underside of the support ring in the open position. The length of the retaining bands and their hinge function allow the screw cap to pivot itself towards the support ring when it is pushed away from the neck of the bottle and to be held therein by tightening.

In another particularly preferred embodiment of the invention, the screw cap is oriented in the open position with its free edge in the direction of the pouring opening. Any remaining filling product, e.g. sweetened lemonade, remains in the open position in the screw cap and therefore cannot contaminate or adhere to the neck of the container.

Further advantages and features become apparent from the following description of three exemplary embodiments of the invention with reference to the schematic drawings. They show, in a schematic representation, not to scale:

Figure 8: A sectional view of the retaining ring of Figure 7 with the angle of inclination shown.

A container closure, indicated in its entirety with the reference numeral 11, is shown in Figures 1 to 6. The closure cap 11 is held in place on the container 13, in particular on a bottle 13. The container 13 is outlined in Figures 1 to 5. The closure cap 11 comprises a screw cap 15, a sealing ring 17 and a first and a second retaining band 19a, 19b.

The closure cap 15 comprises a stopper disk 21 and a first cylindrical cover 23 with a free edge 25. An internal thread 27 is formed on the inside of the cover 23. The container 13 comprises a container body 28 and a container neck 29 which connects to the container body 28. The container neck 29 is formed as a second cylindrical cover. An external thread 31 is formed on the container neck 29, which cooperates with the internal thread 27. In this way, the screw cap 15 can be screwed onto and off the container neck 29. The closure cap 11 closes the pouring opening 33, which is provided inside the container neck 29. The closure cap 11 is shaped to cooperate with a standard container neck 29 with external thread 31 and retaining ring 35.

The retaining ring 17 is held in place by a positive-locking connection on the container neck 13. For this purpose, a retaining ring 35 is formed on the outside of the container neck 29, beneath which the projections 37 formed on the inside of the retaining ring 17 can engage (Figures 7 and 8). The retaining ring 17 is twisted relative to the container neck 29.

The first arm 19a has a first end 39 and a second end 41. The first end 39 is fixedly connected to the free edge 25. The second end 41 is fixedly connected to the securing ring 17. In this way, the container closure 11 is held in the container 13 without being lost.

The second arm 19b has a third end 51 and a fourth end 53. The third end 51 is fixedly connected to the free edge 25. The fourth end 53 is fixedly connected to the securing ring 17. In this way, the closing lid 11 is additionally held on the container 13 without being lost.

The sealing ring 17 is held in place by a plurality of predetermined breaking ribs 63 at the free edge 25, which break when the screw cap 15 is unscrewed from the container neck 29. Preferably, the predetermined breaking ribs 63 are arranged at regular intervals on the sealing ring 17.

It is preferable that the first and second arms 19a, 19b have a width between 1.8 mm and 2.2 mm, or a width corresponding to at least 15% of the height of the securing ring, in order to be sufficiently stable. It is preferable that the retaining bands 19a, 19b have a cross-sectional area of 1 mm2.

The screw cap 15 is, according to Figure 1, in a closed position in which it is snapped or screwed onto the container neck 29. When it is unscrewed from the container neck 29, the first and second retaining bands 19a, 19b are pulled upwards in the axial direction (Figure 2). The retaining bands are also elastically extendable, so that the screw cap 15 can be unscrewed from the container neck 29 and folded outwards.

A first and second receptacle 65, 67 are provided on the retaining ring 17. The first and second receptacle 65, 67 accommodate the first and second retaining bands 19a, 19b. In this way, it is possible to process the first and second retaining bands 19a, 19b directly from the retaining ring 17, for example by cutting them out of the retaining ring 17.

The first, second, third and fourth ends 39, 41, 51, 53 are arranged one after the other in the circumferential direction on the free edge 25 or on the retaining ring 17. Between the second end 41 of the first retaining band 19a and the third end 51 of the second retaining band 19b, an extension 43 is formed, which is part of the retaining ring 17 between the two retaining bands 19a, 19b. A third recess 57 is provided in the retaining ring 17, by means of which a hinge function is provided at the second end 41 of the first retaining band 19a. The third recess 57 thus enables the first retaining band 19a to be folded outwards without material resistance from the retaining ring 17.

During the transition of the screw cap 15 from its unscrewed position to its open position, the first and second retaining bands 19a, 19b function as a hinge, around which the screw cap 15 can be folded into the open position. The hinge effect is enhanced by the first and second folds 69, 71. The first and second folds 69, 71 are provided at the second or fourth end 41, 53.

A support ring 72 is formed at the transition between the container neck 29 and the container body 28. The first and second retaining bands 19a, 19b are dimensioned in length such that the screw cap 15 can be hooked with its free edge 25 in the open position on the underside of the support ring. In the open position, the first and second retaining bands 19a, 19b are preferably elastically tensioned and pivoted.

The arrangement of the ends of the retaining bands 19a, 19b, i.e. that they follow the first end 39, the second end 41, the third end 51 and the fourth end 53 in the circumferential direction and a certain length of the first and second retaining bands 19a, 19b have the advantage that the screw cap 15 can be intuitively rotated upwards and can be hooked with its free edge 25 to the supporting ring 72.

For this purpose, it is necessary that the length of the first or second retaining band 19,19b corresponds to between 27 % and 32 % and preferably between 29 % and 30 % of the outer diameter of the screw cap. The possible dimensions are with a ratio of the outer diameter of the support ring to the retaining band length = 1 : 3.3 converted to standard support ring outer diameters:

Support ring diameter: 33.0 mm -> Band length: in each case approx. 10 mm

Support ring diameter: 42.5 mm -> Band length: in each case approx. 12.9 mm

Support ring diameter: 42.0 mm -> Band length: in each case approx. 12.7 mm

Support ring diameter: 37.0 mm -> Band length: in each case approx. 11.2 mm

Support ring diameter: 31.5 mm -> Band length: in each case approx. 9.5 mm

Support ring diameter: 31.0 mm -> Band length: in each case approx. 9.4 mm

Support ring diameter: 30.2 mm -> Band length: in each case approx. 9.2 mm

Support ring diameter: 29.25 mm -> Band length: in each case approx. 8.9 mm

Since the closing cap 11 or the sealing ring 17 are rotationally symmetrical, they have a central point 73. The central point 73 is located in the plane formed between the free edge 25 and the sealing ring 17. The second end 41 and the fourth end 53 comprise an opening angle 75 of at least 60 degrees and at most 90 degrees and preferably at least 70 and at most 80 degrees relative to the central point 73 as the apex.

If the closing cap 11 is snapped onto the container neck 29, the closing cap 11 has closed the pouring opening 33 and the closing cap 11 is in a closed position. When the screw cap 15 is unscrewed from the container neck 29, the predetermined breaking ribs 63 are broken. The securing ring 17 is turned with the screw cap 15. During unscrewing, the first and second retaining bands 19a, 19b can be straightened.

As already described above, the screw cap 15 is folded into the open position after it has been unscrewed from the container neck 29 in the sense that the screw cap 15 automatically springs upwards with its free edge and in the direction of the support ring 72. The free edge 25 can then be fixed below the support ring 72. In this case, the length of the first and second retaining bands 19a, 19b must be precisely determined in order to enable a latching function. If the length of the retaining bands 19a, 19b is too long, the free edge 25 is not pulled with sufficient force against the support ring 72. If the length of the retaining bands 19a, 19b is too short, the free edge 25 cannot be pulled under the support ring 72 and prevents the filling product from being poured out from the pouring opening 33.

In the open position, the screw cap 15 remains on the container 13 without getting lost and is fixed on the container neck 29 in such a way that when pouring the liquid from the container 13 it does not project into the pouring opening 33. In the open position, the inner side of the cap faces upwards, which means that any filling product adhering to the screw cap 15 remains there and cannot contaminate the container neck 29. This is a great advantage, especially with sugary drinks, since they cannot adhere to the container body.

The first and second retaining bands 19a, 19b enable the screw cap 15 to be moved into the open position in a force-directed folding movement after it has been unscrewed from the container neck 29. Due to the forced direction and length of the retaining bands 19a, 19b, there is only one open position and not several. The length and cross-section of the first and second retaining bands 19a, 19b are thus dimensioned such that the first and second retaining bands 19a, 19b are elastically stretched in the open position of the screw cap 15. The screw cap 15 is thus pulled into the open position at the corner between the container neck 29 and the support ring 72 and is held in this corner without wobbling. The elastic pre-stretching of the first and second retaining bands 19a, 19b also enables the screw cap to be moved from the open position to the closed position and vice versa. In this way, the container 13 can be opened and closed several times and the screw cap 15 remains stable and unwobbled in the open position each time it is opened.

The projections 37 can be designed according to the following illustrative description of Figures 7 and 8. This embodiment of the projections 37 is covered by the Swiss patent applications under application numbers 01467/19 and 01695/19, the publications of which hereby form part of the subject matter of the present patent application. Slots 97 are provided in the retaining ring, which are distributed over the circumference of the retaining ring 17. The slots 97 each have an upper edge 99 and a lower edge 101. The upper edge 99 is formed by a circular arc-shaped section of the retaining ring 17. The lower edge 101 corresponds to the free edge of a wall section 103 which is inclined radially inwards. Due to the inward inclination of the wall section 103, the lower edge 101 has a smaller radius than the retaining ring 17 and can thus strike a support (retaining ring 35) of the container neck 29 when the screw cap 15 is unscrewed from the container neck 29. The support is provided by the retaining ring 35, which is formed on the container neck 29 below the outer thread 31. When the screw cap 15 is unscrewed, the lower edge 99 engages in a positive-locking manner with the retaining ring 35, so that the retaining ring 17 is reliably held even in the event of high axial forces on the retaining ring 35.

Each wall section 101 has a first part section 105 and two second part sections 107. The first part section 105 represents an inwardly folded cover section and is preferably designed flat. The second part sections 107 are connected to the inwardly facing sides of the first part section 105 and connect them to the securing ring 17. The second part sections 107 can be designed folded or flat and are oriented diagonally inwardly relative to one another. The lower edge 101 of the groove 97 corresponds to the free edges of the first part section 105 and the second part sections 107 and lies in a plane 109, which is shown in FIG. 10. The plane 109 is preferably oriented perpendicular to the axis of rotation 110 of the container neck 29. The described design features of the wall section 103 have the advantage that the wall section 103 with the entire lower edge 101 can be positioned on the retaining ring 35 and does not yield in the event of an upward axial pulling force in a hook-like manner. In this way, the securing ring 17 is held in the retaining ring 35 without loosening and can only be removed from the retaining ring 35 by breaking it off. By providing the second partial sections 107, a movement of the first partial section 105 in a radially inward direction is prevented. However, a movement of the first partial section 105 in a radially outward direction is possible. This movement is flexible and the wall section 103 returns to its initial, inwardly inclined position after being pressed radially outward. This can have the additional advantage that the securing ring 17 can be easily removed and fitted with little force onto the container neck 29 together with the screw cap 15. The demoulding of an injection mould and the fitting into the neck 29 of the container can be carried out by the flexibility of the wall section 103, without there being any danger of damaging the wall section 103.

It is preferable that the inclined wall sections 103 have a reduced wall thickness compared to the rest of the securing ring 17. Figure 8 shows that the region of the lower edge 101 has the lowest wall thickness. Thus, the above-described flexibility of the radially outward wall section 103 is further improved. The wall thickness of the wall section 103 is reduced, starting from the lower edge 101 linearly downwards.

In Figures 7 and 8, the sealing ring 17 is shown without the screw cap 15. In Figures 9 and 10, it is clearly visible that an annular rim 111 is formed above the grooves 97 in the sealing ring 17, on which the upper edges 99 are located.

In Fig. 8, a first and second angle of inclination 113, 115 are marked. The first angle of inclination 113 indicates the inclination of the first partial section 105 relative to the plane of the lower edge 101. The first angle of inclination 113 has dimensions of between 60 and 80 degrees and preferably between 65 and 75 degrees. The greater the first angle of inclination 113, the better the stability of the wall sections 103 against the application of vertical forces or axial tensile forces caused by unscrewing the screw cap 15. However, the first angle of inclination 113 is not allowed to be very large, since otherwise the engagement under the retaining ring 35 could not occur properly.

The second inclination angle 115 indicates the inclination of the groove 97 relative to the plane of the lower edge 111. The connecting straight line 117, which represents the inclination of the groove 97, is a connection of the upper edge 99 to the lower edge 101 in a plane, which extends through the axis of rotation 110 and the connecting straight line 117. The second inclination angle 115 is included in the connecting straight line 117 and the plane 109. The second inclination angle 115 has dimensions of between 30 and 50 degrees and preferably between 35 and 45 degrees. The larger the second inclination angle 115, the easier it is to remove the sealing ring 17.

An inwardly projecting inner cone 87 (Figures 5 and 6) is preferably formed on the base 21 of the screw cap 15, e.g. in the form of a sealing cylinder or sealing ring. The inner cone 87 is shaped to cooperate hermetically with the inner wall 89 of the container neck 29 in the closed position. The closing cap 11 can therefore act as a so-called “sealing cone” and effectively seals the container neck 29.

The closing cap 11 is made of a plastic. PP and HDPE are among the preferred plastics.
