Abstract

The fillable closure is used to meter a specific substance into the container equipped with this closure. It can be triggered by means of a push button, so that a substance accommodated directly in the closure or a separately filled receptacle (13) accommodated inside the closure can be emptied into the container equipped with this closure. The closure comprises an associated threaded socket (9) with a flange (11) at its lower end and can be glued or welded to a hole or in a hole of a separate container with this flange (11) in a sealing manner. In an alternative, it comprises a threaded socket (9) of a container connected to it in one piece and a closure cap (1) which can be screwed onto this threaded socket (9) and which, when the closure cap (1) is in the inverted position, either has a fillable cup with a sealing disc (15). a foil for closing the cup, or in which closure cap an associated separately fillable receiving cup (13) can be inserted. The contents of the cup or this receiving cup (13) can be hermetically sealed in the closure cap (1) with the sealing disc (15). Inside the closure cap (1), a tube section (19) protrudes axially downwards. Formed from its inner upper end is an upwardly and outwardly directed deformable dome with a central push button. By pressing down the dome with at least one piercing and cutting element (17) molded or inserted on its underside or formed on the lower edge of its insertable receiving cup (13), the sealing disc (15) flanged onto the lower end of the tube section (19) in the assembled state can be pierced , can be cut open and folded down. The contents of the receiving cup (13) fall into the container.

Description

This invention relates to a fillable closure which can be released by means of a push button, so that a substance housed directly in the closure or a separately filled receptacle housed inside the closure is thereby emptied into the large container with which the closure is equipped. Many drinks are already made today by mixing a concentrate with water. Instead of distributing the finished mixture, it would be much more efficient if the bottlers could only bottle water on site and the concentrate was only added to the water in the bottle and then mixed with it when the consumer opened the bottle for the first time.

A known solution for dosing a separate liquid is a plastic dosing cap with associated container neck for a container. It consists of a threaded cap, a capsule inside that can be filled separately and closed with a film or closed after filling, and an associated container neck. The capsule is oriented with its closure foil down and held within the container finish. When the cap is placed on the container neck, it protrudes into the interior of the container neck, and there is a piercing and cutting device on the lower edge of the container neck, by means of which the closing foil at the lower end of the capsule can be opened when the plastic dosage closure is opened for the first time, so that the substance contained in the capsule falls into the container. When turning counterclockwise - i.e. in the loosening direction - on the container neck, the threaded cap is initially pushed downwards due to an opposing thread, whereby the film of the capsule inside the container neck is pressed over a piercing and cutting device and thus cut open, while the threaded cap is on the Container neck finally finds a stop. When the threaded cap is turned further in the loosening direction, it takes the container neck with it, which in turn sits on the container socket with a thread, but this requires a greater torque to unscrew it. If the threaded cap is turned further, it takes the container neck and the now empty capsule lying therein with it, and the entire closure is screwed off the container neck. The disadvantage of this solution, however, is that it is complex in terms of construction and execution, since left-hand and right-hand threads are required, and the assembly of the closure is also not without problems.

The object of the present invention is to create a fillable closure which itself forms a water vapor and oxygen-tight, fillable cup or can accommodate a water vapor and oxygen-tight receiving cup to be filled separately, and which is simpler to manufacture and to use assembly, consists of a minimum number of parts and is operable by a single action - a single action - to safely and completely empty the contents of the filled cup or receiving cup into the container fitted with the closure.

This object is achieved by a fillable closure for metering a specific substance into the container equipped with this closure, and which can be triggered by means of a push button, so that a substance accommodated directly in the closure or a separately filled receptacle accommodated inside the closure (13) thereby dischargeable into the equipped container with which the closure is equipped, the closure comprising an associated threaded neck with a flange at its lower end, with which flange the threaded neck sealingly sticks onto a hole or into a hole of a separate container - or is weldable, or comprises the threaded socket of a container connected to it in one piece, as well as with a closure cap which can be screwed onto this threaded socket, which, when the closure cap is in the inverted position, forms either a fillable cup with a sealing disk made of a foil for closing the cup det, or in which closure cap an associated separately fillable receptacle can be inserted, whereby the contents of the receptacle or receptacle with the sealing disc can be hermetically sealed in the closure cap, and which is characterized in that inside the closure cap a tube section protrudes axially downwards and from its inner upper end, an upward and outward-pointing deformable dome with a central push button is formed, and by pressing down the dome with at least one lancing and cutting element formed or inserted on its underside or formed on the lower edge of its insertable receiving cup, the im mounted state at the lower end of the pipe section flanged sealing disc from a film pierceable, cut open and foldable.

In the figures, two embodiments of this fillable closure are shown with a push button in several views. These closure variants are described in detail on the basis of these figures and their function is explained.

[0006] It shows: FIG. 1 The closure cap of the closure with a protective edge and a central push-button shown obliquely from above; FIG. 2 shows the closure with the closure cap, protective rim and central push button seen obliquely from above, with the associated threaded connector; FIG. 3 shows the closure cap according to FIG. 1 viewed obliquely from below; FIG. 4 shows the closure cap according to FIGS. 1 to 3 seen from below, with a view of the inside; FIG. 5 shows this closure cap in a diametrical section; FIG. 6 shows the closure with closure cap and associated threaded connector in a second variant in a perspective view obliquely from above; FIG. 7 shows the closure according to FIG. 6 with all components, namely from above with closure cap, receiving cup, sealing disc and threaded connector, in a perspective view obliquely from above; FIG. 8 shows the closure according to FIGS. 6 and 7 with all components, namely shown from above with closure cap, receiving cup, sealing disc and threaded connector, in a perspective view obliquely from below; FIG. 9 shows the closure with the receiving cup in the constellation for its insertion into the closure cap, and with the sealing disc for later sealing of the substance previously filled into the receiving cup in the upside-down position of the closure; FIG. 10 shows the closure in a diametrical section in order to understand the effect of the receiving cup on the sealing disc, with the crown edge of the piercing teeth running at an acute angle to the flanged sealing disc on the lower edge of the receiving cup; FIG. 11 shows the closure in a perspective, diametrical section to understand the effect of the receiving cup on the sealing disk, with a spot in the crown edge which has no teeth and is intended to act as a hinge for folding down the sealing disk; FIG. 12 shows the cutting out of a circular disk from the sealing disk by a circumference of approximately 340° outside the closure cap—in a theoretical representation; Figure 13 The continuation of the sealing disk opening from the situation in Figure 12, by folding it around the hinge area at the edge of the crown.

In Figure 1 only the cap 1 of the closure is initially shown. As a special feature, it forms an outward-facing, deformable dome 5, which is surrounded by a protective edge of the same height, i.e. by an inner ring wall 3, which merges at the top into a bridge 4 leading radially outwards, and then into the outer one, which is directed downwards again Ring wall 2, which is equipped with gripping ribs 27. The dome 5 has very thin walls so that it can be deformed at the zenith when it is pressed axially on its pusher surface 6 . The inner ring wall 3 and the outer ring wall 2 reach up to the zenith of the dome 5 so that they form a protective ring running around the outside of the dome, which protects the push button surface 6 from being actuated unintentionally. The pusher surface 6 can be pushed down in the axial direction. This causes the filling to be emptied as will be described below. A guarantee film 8 can be glued onto the surrounding protective ring, as indicated in FIG. 1, which covers the depressible dome 5 as a tamper-proof guarantee. You can then see the pusher surface 6 only after removing this guarantee film 8, or the guarantee film 8 must be pushed through in order to press the dome 5 down. At the lower end of the closure cap 1 one can still see the lower end of the inner tube section 19, which is used for filling with a separate substance. However, the closure can also be designed without these annular walls 2, 3, in that an annular wall with an internal thread is formed below the dome, although this embodiment is not shown here in a figure. In this case, the dome can be covered with an associated protective cap to prevent the dome 5 from being depressed unintentionally. This protective cap can be connected in one piece to the closure via a film hinge and then be injection molded together with it, and the protective cap can then be pivoted onto the dome and clicked onto it with its edge. In a variant, the protective cap can also be designed as a separate part, which can then be slipped over the dome and clicked onto the closure.

2 shows this closure cap 1 with the associated threaded connector 9 with an external thread 10 shown underneath, with a flange 11 at its lower end and a radially projecting ring 12 running all around. FIG. 3 shows the closure cap 1 in an illustration , which allows a view from below into its interior. A tube section 19 projects downwards, which continues downwards with the diameter of the dome and is suitable for receiving a separate liquid or free-flowing substance. A stepped shoulder 20 is formed near the lower edge, onto which a sealing disc made of a film can be placed after filling and the protruding edge region 14 can be flanged onto this shoulder 20 . This is done by heating and folding the protruding edge area 14 of the pipe section 19 onto this shoulder 20. Inside the pipe section 19 you can see the piercing and cutting elements, here in the form of piercing and cutting teeth 22.

The figure 4 shows the cap seen from below. As can be seen, the three piercing and cutting teeth 22 here are formed on the inside of the dome 5 . Each piercing and cutting tooth 22 terminates in a piercing tip 23 at its outer end. From this lancing tip 23 lead away on both sides at an oblique angle to the axial direction of the pipe section 19 cutting edges 25. The lancing and cutting elements 22 on the inside of the dome form a group of three of lancing and cutting teeth 22 pointing axially downwards, the lancing - And cutting teeth 22 are curved along a common peripheral line 29, on which peripheral line 29 they are formed. Two of the pricking and cutting teeth 22 are diametrically opposed to each other and a third is between these two diametrically opposed pricking and cutting teeth 22 on the same circumferential line 29. In the center between these pricking and cutting teeth 22 is on the underside of the pusher surface 6 at least an axially extending profile 26 is formed. If the dome 5 is pressed downwards by pressing a finger on the pusher surface 6, the three piercing and incising teeth 22 first pierce the sealing disk flanged onto the shoulder 20 at three points with their tips 23, and then cut the cutting edges 25 continue on both sides of the punctures until a circular disk has been cut out of the sealing disk 15 by approximately 270° along the peripheral line 29 . The T-profile 26 in the center acts as a ram and pushes the circular disc further down and breaks the material bridges between the piercing and cutting teeth, which have not yet been cut open by them, and in the free space on the peripheral line 29, where no piercing and Incisor 22 is, there is another cross-section T-shaped profile 24, which also acts as a ram. When the deformable dome 5 is pushed further downwards, due to the geometric arrangement of the piercing and cutting teeth 22 on the inner wall of the dome, the same are pivoted outwards in the radial direction. The central T-profile 26 acts as a pusher and breaks the material bridges that have remained on the sealing disc 15 between the piercing and cutting teeth 22. If the dome 5 is pressed down further, the outer T-profile 24 on the peripheral line 29 comes into action. It acts as a ram and pivots the circular disc, which is now almost completely cut out of the sealing disc 15, downwards by approximately 90°. The passage is thus opened up to the maximum, so that the substance inside the pipe section 19 reliably falls down into a container which is equipped with this closure. In a special embodiment, these piercing and cutting teeth 22 and ram profiles 24, 26 can be formed in one piece on a separate base plate. This base plate then has a hump on its outside, with which it can be clicked into a corresponding recess formed on the underside of the dome 5 . A container is equipped with this closure in such a way that the threaded socket 9 of the closure with its flange 11 is either glued or welded onto the edge of the hole, or is pushed into such a hole from below until its flange 11 rests on the inside of the edge of the hole and there is glued or welded to it. This is possible if it is a composite pack which, after installing the threaded connector 9, is filled in the upside-down position and then sealed tightly at the part of the composite pack that ultimately forms the underbody. It is clear that the threaded connector 9 can also belong in one piece to a plastic or PET bottle.

The figure 5 shows the closure in a diametrical section. It can be seen here how the piercing and cutting teeth 22 and the profiles 24, 26 are formed on the inside of the dome 5. The piercing and cutting teeth 22 protrude furthest down. The central profile 26 protrudes somewhat less downwards, and the profile 24 formed on the peripheral line 29 protrudes the least downwards. When pressing down the pusher surface 6 and deforming the dome 5, the piercing and cutting teeth 22 first become effective and each cut a circle segment from the sealing disk 15, which rests on the shoulder 20 and previously onto this by heating and folding the edge areas 14 of the pipe section 19, as indicated by arrows, was flared. Then the central profile 26 becomes effective and presses the sealing disk 15 downwards and thus tears open the material bridges between the three piercing and cutting teeth 22 that have remained on it. Depressing the dome still further will pivot the piercing and cutting teeth 22 radially outward and then the profile 24 will come into action. It pivots the circular disk, which is now cut out of the sealing disk by about 340°, downwards into the threaded connector, which is not shown here.

Figure 6 and the following show an alternative embodiment, in which the closure cap 1 is suitable with its tube section for receiving a separately filled with a substance and closed capsule in the form of a receiving cup, which can also be opened by depressing the dome 5. FIG. 6 shows this closure with the closure cap and the associated threaded connector 9 in a perspective view obliquely from above. The closure cap 1 again consists of an outer annular wall 2 and an inner annular wall 3 which are connected to one another via a bridge 4 . At the lower end of the inner annular wall 3, this transitions in the radial direction into a base, on the underside of which a tube section extending downward is formed, while a dome 5 is formed on its upper side. At the zenith, this forms an outwardly protruding pusher surface 6. At the lower end of the closure cap 1, a guarantee ring 7 can be seen, which is held in a known manner by a number of material bridges acting as predetermined breaking points at the lower edge of the closure cap 1. The associated threaded connector 9 can be seen below the closure cap 1. This forms a thread 10 on its outside. The threaded connector 9 terminates in a radially projecting flange 11 at its lower end. You can also see an all-round, radially protruding ring 12. The guarantee band 7 on the closure cap 1 can click into this when screwing onto the threaded socket 9 and from then on the closure cap 1 can only be unscrewed from the threaded socket 9 by breaking the material bridges. With the flange 11, the threaded connector 9 can be welded or glued into a hole in a container. The flange 11 can come to rest on the outside of the edge of the hole or inside along the edge of the hole if, for example, a container made of composite material is still open on its underside and is only closed after the container has been filled upside down. In addition, the threaded connector 9 can also belong in one piece to a plastic container, for example to a PET bottle.

Figure 7 shows the closure of Figure 6 with all components, namely from above with the closure cap 1, including the receiving cup 13, the sealing disc 15 and the threaded connector 9, shown in a perspective view of all components diagonally from above. In the position shown, the receiving cup 13 fits into the closure cap 1 and is pushed into it from below in the axial direction until its hump 16 on its upper side clicks into the depression on the underside of the pusher surface 6 at the zenith of the dome 5 of the closure cap 1 is formed. At the lower edge of the receiving cup 13 one can see continuous piercing teeth 17 here, except for a point 18 where no teeth are formed. The lower edge of the receiving cup therefore forms a crown edge of piercing teeth 17 around approximately 340° of its circumference. Below the receiving cup 13 the sealing disk 15 is shown. This can either be made from a material that is impermeable to water vapor and oxygen, for example from an aluminum foil or a laminate that contains an aluminum foil, or from another suitable laminate that has these properties. The threaded connector 9 is shown at the bottom.

The same components are shown again in FIG. 8, but now shown in a perspective view of all components seen obliquely from below. In this view one can see the axially running pipe section 19, which is formed inside the closure cap 1 and which protrudes downwards and is open at the bottom. On its inside, in the area of its lower edge, it shows a stepped shoulder 20 along the circumference. This is used for placing the sealing disc 15 from the outside after inserting and filling the receiving cup 13 in the upside down position, as will be described in more detail below. On the inside of the outer ring wall 2 of the closure cap 1 one can still see a small section of the thread turn 21 of the internal thread formed on this wall 2 .

Below the closure cap 1, the receiving cup 13 is shown. In this representation one can see the crown edge with the closed row of spikes 17 and the section 18 where such spikes 17 are missing. The sealing disc 15 is shown below the receiving cup 13, and at the bottom the threaded socket 9 with its clearly visible flange 11 and the circumferential ring 12. The receiving cup 13 can be inserted into the pipe section 19 and into the dome 5 adjoining it. And a substance can be filled almost to the shoulder 20 of the receiving cup 13, be it a liquid or free-flowing substance, into this receiving cup 13 clicked into the dome from below when it is in the upturned position together with the closure cap 1. Finally, the receiving cup 13 is hermetically sealed by placing the sealing disc 15 on its shoulder 20 and crimping the sealing disc 15 onto this shoulder 20 .

9 shows the components closure cap 1, receiving cup 13 and sealing disk 15, as they are arranged in sequence. The receiving cup 13 is clicked into the pipe section 19 and the dome 5 from below in an empty form. Then the closure cap 1 is turned 180° and in this position the receiving cup 13 is filled with a special substance that can later be added to the contents of the container equipped with the closure. Then the sealing disc 15 is placed on the internal shoulder 20 on the pipe section 19 and the edge area of the pipe section 19 is folded down hot onto the sealing disc 15 and pressed so that it is flanged hermetically onto the shoulder 20 at the end.

The figure 10 shows the closure in a diametrical section and this view explains why the opening of the sealing disk 15 works reliably. The crown edge with the piercing teeth 17 on the lower edge of the receiving cup 13 is advantageously arranged at a slight incline to the sealing disc 15 so that it encloses a very acute angle with it. This is indicated with the dashed line A. If one presses on the pusher surface 6 and thereby presses the receiving cup 13 down inside the tube section 19 , the piercing teeth 17 located at the lowest point first pierce the sealing disk 15 . The piercing force is concentrated on a few teeth. After that, the other piercing teeth 17 gradually come into effect, so that the cutting of the sealing disc into two almost complete semicircles starts from one point and the piercing force is therefore only ever concentrated in small areas. FIG. 11 shows the same diametrical section, but seen here in a perspective view obliquely from above. Here you can see point 18 on the edge of the crown where no teeth are formed. This point 18 comes into effect when the receiving cup 13 is depressed at the end. It presses the circular disk cut out of the sealing disk 15 at this point around the shoulder 20 downwards, so that radially outside the point 18 the circular disk folds down in a hinged manner by approximately 90° and is pivoted into the threaded socket. This allows the substance in the receiving cup 13 to fall reliably and completely through the threaded connector into the container equipped with the closure.

12 shows the opening process, ie the cutting out of a circular disc from the sealing disc 15 in a virtual view, so to speak, because this opening process takes place with the receiving cup 13 inserted, which is shown here outside the closure cap. However, the outer edge of the sealing disc 15 is firmly connected to the shoulder 20 in the closure cap or flanged onto it. The depressed receiving cup 13 with its lower crown edge of teeth 17 pierces the sealing disk 15 along a peripheral line and thus cuts a circular disk out of it around a circumference of approximately 340°. FIG. 13 shows the subsequent process when the receiving container 13 is pressed further down. Then the cut-out circular disk is folded down around the point 18 on the edge of the crown that has no teeth, around the shoulder 20, by approximately 90°, and it then protrudes into the threaded socket 9 and releases the flow, so that the contents of the Receiver cup 13 falls safely and completely into the container equipped with the closure.
