Said dispenser closure comprises: a closing body (100) with a cover (120) from whose outer rim a jacket (110) extends downward that can be fastened via an opening of the container on the same, an outlet opening (126) in an upper face of the closing body (100), which communicates with the opening of the container, and a closure element (200) for opening or closing the outlet opening (126) of the closing body (100), and a dome-shaped raised section (124) of the closing body (100), which is disposed around the outlet opening (126) of the closing body (100). The closing body (100) is provided with a covering element (150) that covers at least partially an outer area of the dome-shaped raised section (124), the material of the covering element (150) being softer than the material of the dome-shaped raised section (124) and/or the cover (120) and/or the material of the closing body (100). The invention allows for an increased tightness of the dispenser closure and a pleasant feel when the user comes into direct contact with the dispenser closure.
Description
- J_ -~OIi:. v'.'",.,O_r! _ =io'v,i.ng Trie invention relates to a dispensir,g closure Tor containers which cori tain free-flowing substances, in particular for drinks coritair,ers.
Numerous designs of dispensirig closures of this type are l:.nown from the prior art, and the closures are used for drinks containers made from various materials, in particular from glass and plastic.
In particular in recent years, increased demands have been imposed on drinks containers of this type and associated dispensing closures for various intended uses and applications, in which context on the one hand reliable sealing of the dispensing closure even under high levels of loads, as occur for example when the drinks containers are carried along duri.ng sporting activity, causes problems, and on the other hand it is desirable for the user of the containers to have as pleasant an experience as possible during removal of the substances, in particular when drinking, when the user's mouth generally comes into direct contact with the dispensing closure.
Therefore, it is an object of some embodiments of the present invention to provide an improved dispensing closure for containers which contain free-flowing substances, in particular for the abovementioned drinks containers, which on the one hand ensures an improved sealing of the dispensing closure and on the othex hand allows a pleasant sensation to be felt in the event of direct contact with the dispensing closure.
This object is achieved in some embodiments by a dispensing closure for containers which contain Tree-flowing substances, in particular for drinks containers, the dispensing closure comprising: a closure body having a cover, from the outer edge of which projects a casing which can be secured to the container over an opening in the container, an outlet opening in a top side of the closure body, which is in communication with the opening in the container, and a closure element for opening and closing the outlet opening of the closure body, a dome-like elevation of the closure body, which is arranged around the outlet opening in the closure body, which is provided with a sleeve element which at least partially covers an outer region of the dome-like elevation, the material of the sleeve element being softer than the material of the dome-like elevation and/or of the cover and/or of the material of the closure body.
According to one aspect of the present invention, there is provided a dispensing closure made from plastic for containers which contain free-flowing substances, in particular for drinks containers, the dispensing closure comprising: a closure body having a cover, from an outer edge of which projects a casing which can be secured to the container over an opening in the container, a substantially horizontal annular shoulder of the cover, from a radially inner region, with respect to the longitudinal center axis, of which a dome-like elevation extends outward, with an outlet opening, which is in communication with the opening in the container, at its outer end, a sleeve element, which at least partially covers an outer region of the dome-like elevation and the material of which is softer than the material of the dome-like elevation, a closure element for the outlet opening, wherein the dome-like elevation forms a drinking stub, the outlet opening of which has a termination edge which is bent off radially inward and in its top region runs substantially horizontally, the sleeve element being made - 2a -of thermoplastic polyester, dimensioris of the sleeve element and of the drinking stub, and also of a cylinctrical pinch member provided on an inner side of a head plate of the closure element, being matched to one another in such a way that, in the closed position of the closure element, the pinch member engages over the dririkinq stub with the sleeve elemerit arranged thereon with substantially no noise.
This dispensing closure of embodiments of the invention has a very positive influence on the contact sensation of the user who, for example during drinking, comes into contact substantially or exclusively with the sleeve element, which consists of the softer material. Furthermore, the sealing of the dispensing closure is improved by the softer material used for the sleeve element, since the closure element which closes off the outlet opening preferably seals off the outlet opening by direct contact with the sleeve element. Furthermore, the fact that the softer material is highly compressible means that it is possible to select the dimensions of the components in such a way that while a reliable seal is obtained, it is not necessary to impose excessively high demands on the accuracy of the manufacturing tolerances. If necessary, it is additionally possible to provide a tamperproofing means in the form of a closure for the outlet opening of the closure body. In this way, in order to maintain the quality of the contents of the pouch, any possibility of air or oxygen reaching the interior of the container is ruled out until the container is opened for the first time. This - { -amper~roo=_r,g mear:s m.ay cons_sL of _ame a.= L_r!e '! e _v e ! emenL ai,d / ri= Of Lh e ?iiar -_a.~ oi L:"!e closure boCly. ! ri additlon to 1;1 thls UJay ac!'._av'-?1g a high level cf quality Gssurance for the cont.ents o: the contair,er, it is thereby possi}le to significantly s i mpl i fy and reduce the costs of mass productior, of the dispensing closure. Therefore, sorne embodimerits of the present invention are based on the surprising discovery that the provision of the sleeve element consisting of softer material makes it possible to achieve or solve both the abovementioned objects or problems.
A further advantage of the dispensing closure having the sleeve element consisting of soft material is the noise insulation, since there is no disruptive noise produced when a lid, in particular a hinged lid, is opened and closed. This is advantageous in particular if, for example, a corresponding container is to be opened as unobtrusively as possible in a quiet atmosphere, for example in a library or during a lecture.
In some embodiments suitable materials for the sleeve element are in particular thermoplastic polymers, in particular thermoplastic polyester (TPE), high-pressure polymers (low-density polyethylene, LDPE), but also other soft plastics, rubber and/or silicone. These materials can be set to the desired softness of the sleeve element but are also stable enough to ensure a long service life of the sleeve element and therefore of the dispensing closure.
Of course, it is possible for the sleeve element to be made from a combination of two or rnore of the abovementioned materials without departing from the subject matter of the present invention.
It is in some embodiments possible for the closure body to be formed integrally with a dome-like elevation which projects -ihe 7:op ~_de or edge o= _losure bDzly and can ~:,e u: ed. as a dr_ni:i ng s--_ub -or the user. Fu= the_mc_e, it is in some embodiments possible for the diameter of the dom=-l=ike e,levati on --.o be stepped over its hei ght, the dom_- ~_ke elevation pr-ferably having a smaller diameter toward its outer region and having the opening at its outer erid .
In some embodiments, the sleeve element is designed in such a way that the dome-like elevation, in its outer region, is covered by the sleeve elemerit substantially completely, i.e. if appropriate including the opening and/or its tamperproof closure made from the material of the closure body. This ensures that the entire area which can come into contact with the mouth of a person who is drinking is covered by the sleeve element, so that the pleasant contact sensation is fully retained. Furthermore, this allows the configuration of the closure element to be made more variable, because a mating element, provided for sealing purposes, of the closure element can engage at various locations of the sleeve element and thereby ensure a seal. For example, if the tamperproof element is designed as a tear-off tab which seals the opening, the user, for example a cyclist, can tear off the tear-off tab using his teeth, without having to use one of his hands, while cycling in order to open the container.
However, the sleeve element may extend only over certain partial regions of the dome-like elevation, in particular over an upper region of the dome-like elevation. This configuration., in particular the size of the dome-like elevation, can be appropriately adapted to the desired use by a person skilled in the art.
By contrast, the sleeve element may extend not only over the dome-like elevation and, if desired, over _ts ~.._n =a :. _r!c_ rCiuy SO C C, _- -' - i:,__ _=g=ons of --he closu'-e body.
In some embodiments, the closure element is a ~ r!;,;gesi lid which is articulatedly mounted in tegrally on the closure body by mearis of a hinge. Therefore, the closure element and the closure body form a single unit which is injection-molded integrally from plastics material and in which the closure element is not lost i0 afte.r it has been fitted to the container.
Of course, it is also possible for separate closure elements to be provided instead of a closure element which is connected to the hinged lid. Furthermore, 15 without departing from the scope of the invention, it is conceivable to use all possible closure options, e.g. a closure element which is secured to the closure body by a snap.-action mechanism or a screw thread.
20 The invention is described in more detail below with reference to a diagrammatic drawing of exemplary embodiments of a dispensing closure. In the drawing:
fig. 1 shows an opened dispensing closure in the form 25 of a center longitudinal section;
fig. 2 shows a second embodiment of a dispensing closure in the form of a center longitudinal section as in fig. 1;
fig. 3 shows a third embodiment of a dispensing closure in the same form of illustration as in figs. 1 and 2;
fig. 4 shows a fourth embodiment of a dispensing closure in the same form of i l 1 ustration as i n figs. 1 - 3; and fig. 5 shows a three-dimensional illustration of the dispensing closure from fig. 4.
Fig. 1 shows a dispensing closure 10 for containers which contain free-flowing substances, having a closure body 100 and a closure element 200 designed as a lid.
The closure body 100 and the closure element 200 are connected to one another on one side by means of a hinge 290, which is designed as an integral hinge, so that the closure element 200 can be pivoted through 180 , about an axis formed by the integral hinge 290, from the position in which it opens up the closure body as shown in fig. 1 into the position in which it closes the closure body.
On its top side, the closure body 100 has a cover 120, from the radially outer edge of which a casing 110 extends laterally. The casing 110 is of substantially cylindrical design and has an internal screw thread 112, by means of which it can be screwed onto a container (not shown) having a corresponding mating screw thread and can thereby be secured in place.
As an alternative to the screw connection, it is also possible to provide other ways of securing the closure body on a container, e.g. snap-action connections. It is also possible for the dispensing closure to be formed directly integrally with a corresponding container.
In the embodiment shown in fig. 1, in the upper region of the casing 110 of the closure body 100, in the vicinity of the outer edge of the cover 120 of the closure body 100, there is a sealing lip 114 which is designed in the form of a ring which slopes downward slightly with respect to the horizontal, so that this sealing lip 114, when the closure element 100 is being screwed onto the container, presses onto and seals a top side of the container opening.
In the embodiment shown here, the sealing lip 114 is formed integrally with the closure body but consists of a soft material, in this case silicone, unlike the hard plastic from which the closure body 100 and also the closure element 200 of the dispensing closure 10 are made. However, at this point it should be noted that in another embodiment the sealing lip 114 may be made from the same material as the closure body 100, which simplifies the production process.
The cover of the closure body 100 has a substantially horizontal annular shoulder 122, from which a radially inner region, with respect to the longitudinal center axis, extends outward beyond the annular shoulder in the style of a dome and in stepped form, the diameter of the dome-like elevation 124 being stepped over its height, and the dome-like elevation 124 having an outlet opening 126 at its outer end.
The dome-like elevation substantially comprises a first (or upper) step 128, which, with respect to the cover 120, lies above a second (or lower) step 134. Each of the steps 128, 134 is substantially cylindrical in form, with the two steps 128, 134 having similar heights, but the first step 128 having a smaller diameter. The transitions between the first step 128 and the second step 134 and between the second step 134 and the annular shoulder 122 on the outer side are rounded, so that there are no sharp edges. Above the first step 128 there is a termination rim 136 of the outlet opening 126 which is bent off radially inward and in its top region runs virtually horizontally.
The inner region of the dome-like elevation 124 of the cover 120 is also stepped: beneath the smallest internal diameter of the outlet opening 126 within the dome-like elevation, the internal diameter of the dome-like elevation widens out in the downward or inward direction. After a first widening of the internal diameter directly beneath the termination rim 136, the inner region extends substantially cylindrically over the entire axial extent (in the direction of the height) of the first step and widens out further approximately at the height of the transition region between the first step 128 and the second step 134.
The lower end of the first step 128 of the flexible tube holder 180, in the inner region, forms an annular stop face 130, which at the same time delimits an annular groove 132 in the upper region within the second step 134. The inner region of the second step 134 below the annular groove 132 has a frustoconical profile and widens out downward, merging at its bottom end into the lower side of the horizontally positioned annular shoulder 122 of the cover 120.
The closure element 200 is substantially designed in the form of a lid and comprises a head plate 210 and a side region 220 which extends from the head plate, the side region 220 substantially being designed in such a way that, in a closed position of the closure element 200, it is substantially flush with the casing 110 of the closure body 100.
Furthermore, on its opposite side from the hinge 290, the closure element 200 has a groove 260 for receiving a quality assurance element 160, the groove 260 (in the lower region in the position of the closure element 200 shown in Figure 1, and therefore in the upper region in the closed position) being recessed inward, so that the quality assurance element 160 can be pressed into this recessed region in order to break the seal. The groove 260 for the quality assurance element 160 is delimited by a lug 262 and a protuberance 264 in its upper and lower regions.
The embodiment shown in fig. 1 has a sleeve element 150 which consists of thermoplastic polyester (TPE), extends substantially over the entire outer region of the dome-like elevation 124 of the cover 120 and follows the contour of the dome-like elevation 124.
The dimensions of the sleeve element 150 made from thermoplastic polyester and of the dome-like elevation 124 and a pinch member 280, which is provided on the inner side of the head plate 210 of the closure element 200 and is substantially circular in design, are matched to one another in such a way that, when the closure element 200 is closed virtually without any noise, the pinch member 280 engages over the first step 128 of the dome-like elevation 124 with the sleeve element 150 arranged thereon, and in this way closes off the outlet opening 126 in a sealed manner with respect to the outside.
In the embodiment shown in fig. 1, the external diameter of the sleeve element 150, at the height of the first step 128, in its uncompressed state is slightly larger than the internal diameter of the circular pinch member 280 of the closure element 200, so that as a result of the closure element 200, which is designed as a hinged lid, being closed, with the sleeve element 150 being slightly compressed at the same time, a press fit is produced between the pinch member 280 and sleeve element 150, which leads to reliable sealing at this location, even if minor manufacturing tolerances in the geometry and/or dimensions of the individual elements are present, which is inevitable at least to a small extent, in particular in the case of mass production or else relatively expensive production processes will be required in order to comply with more accurate tolerance requirements.
Purely for the sake of completeness, it should be noted that the embodiment of the dispensing closure shown in fig. 1 is designed in such a way that it is additionally also possible for a flexible dispensing tube to be inserted into the inner region of the closure body 200, which flexible dispensing tube is fixed securely in the inner region of the dome-like elevation 124, with its outer end projecting out of the outlet opening 126, in order if necessary to make it even easier for the free-flowing substances to be removed.
Fig. 2 shows a further embodiment of a dispensing closure, which is substantially identical to the embodiment shown in fig. 1.
Unlike in the embodiment shown in fig. 1, however, the sleeve element 150 is designed in such a way that it covers only an upper region of the dome-like elevation 124, namely the first step 128 and the transition between the first step 128 and the second step 134 of the dome-like elevation 124. Furthermore, in this embodiment the sleeve element 150 is made from a low-density polyethylene (LDPE).
In the embodiment shown in fig. 3, a dispensing closure is designed substantially in the same way as in the embodiment shown in fig. 1. However, the outlet opening 126 in the top side of the closure body 100 is provided with a tamperproof closure 300. This tamperproof closure 300 forms an integral part of the dispensing closure 10 and for this purpose is made from the relatively soft material of the sleeve element 150. A
weakened line 302, which follows the edge of the outlet opening 126 in the dome-like elevation 124, connects the tamperproof closure 300 which seals off the outlet opening 126 to the sleeve element 150. It is advantageous for a tear-off tab 304 to be connected to the tamperproof closure 300 and preferably to be formed integrally therewith. The tear-off tab 304 makes it easy to open the container by tearing off the tear-off tab 304 even if this cannot be done by hand, as is the case, for example, in cycling races or the like.
The tamperproof element 300 therefore ensures that air or oxygen cannot adversely affect the quality of the contents of the container until the container or bottle is opened for the first time. In this case too, the sleeve element 150 together with the tamperproof closure 300 may consist of thermoplastic polyester (TPE) and/or of low-density polyethylene (LDPE), or of rubber, silicone and/or a soft plastic or a combination of these materials.
The embodiment of a dispensing closure 10 shown in fig. 4 differs from that shown in fig. 3 only through the fact that a tamperproof closure 400 is made from the material of the closure body 100 and is produced together with the latter as an integral workpiece using the plastics injection-molding process. This tamperproof closure 400 is exposed at the top or outside and is connected or produced integrally with the closure body 100 by a weakened line 402 which follows the annular edge of the outlet opening 126. A
tear-off tab 404, which as in fig. 3 projects obliquely from the top side of the tamperproof closure 400, consists of the same material as the closure body 100 and is intended to facilitate opening of the container provided with the dispensing closure 10 but to ensure that the quality of the contents of the container is preserved until it is opened by hermetically sealing the outlet opening 126 of the container. The closure body 100 is produced integrally with the tear-off tab 404, preferably from polypropylene (PP) or polyethylene (PE) using the injection-molding process.
Of course, if necessary it is also possible for the tamperproofing means 400, which consists of the material of the closure body 100, and its tear-off tab 404 additionally to be covered with the soft material of the sleeve element 150, in particular if a container equipped therewith is to be used for a purpose in which the container cannot be opened by hand or can only be opened by hand with difficulty, as is the case in certain forms of sport, such as for example cycling etc.
Fig. 5 gives a general impression of the described dispensing closure from figs. 3 and 4, with the dispensing closures shown in figs. 1 and 2 also being comparable to the illustration of the dispensing closure provided in fig. 5 if one imagines that the tamperproof closure 400 and the tear-off tab 404 are absent, and instead there is an open outlet opening 126 of the closure body 100.

Numerous designs of dispensirig closures of this type are l:.nown from the prior art, and the closures are used for drinks containers made from various materials, in particular from glass and plastic.

In some embodiments suitable materials for the sleeve element are in particular thermoplastic polymers, in particular thermoplastic polyester (TPE), high-pressure polymers (low-density polyethylene, LDPE), but also other soft plastics, rubber and/or silicone. These materials can be set to the desired softness of the sleeve element but are also stable enough to ensure a long service life of the sleeve element and therefore of the dispensing closure.
Of course, it is possible for the sleeve element to be made from a combination of two or rnore of the abovementioned materials without departing from the subject matter of the present invention.
It is in some embodiments possible for the closure body to be formed integrally with a dome-like elevation which projects -ihe 7:op ~_de or edge o= _losure bDzly and can ~:,e u: ed. as a dr_ni:i ng s--_ub -or the user. Fu= the_mc_e, it is in some embodiments possible for the diameter of the dom=-l=ike e,levati on --.o be stepped over its hei ght, the dom_- ~_ke elevation pr-ferably having a smaller diameter toward its outer region and having the opening at its outer erid .
In some embodiments, the sleeve element is designed in such a way that the dome-like elevation, in its outer region, is covered by the sleeve elemerit substantially completely, i.e. if appropriate including the opening and/or its tamperproof closure made from the material of the closure body. This ensures that the entire area which can come into contact with the mouth of a person who is drinking is covered by the sleeve element, so that the pleasant contact sensation is fully retained. Furthermore, this allows the configuration of the closure element to be made more variable, because a mating element, provided for sealing purposes, of the closure element can engage at various locations of the sleeve element and thereby ensure a seal. For example, if the tamperproof element is designed as a tear-off tab which seals the opening, the user, for example a cyclist, can tear off the tear-off tab using his teeth, without having to use one of his hands, while cycling in order to open the container.
However, the sleeve element may extend only over certain partial regions of the dome-like elevation, in particular over an upper region of the dome-like elevation. This configuration., in particular the size of the dome-like elevation, can be appropriately adapted to the desired use by a person skilled in the art.
By contrast, the sleeve element may extend not only over the dome-like elevation and, if desired, over _ts ~.._n =a :. _r!c_ rCiuy SO C C, _- -' - i:,__ _=g=ons of --he closu'-e body.
In some embodiments, the closure element is a ~ r!;,;gesi lid which is articulatedly mounted in tegrally on the closure body by mearis of a hinge. Therefore, the closure element and the closure body form a single unit which is injection-molded integrally from plastics material and in which the closure element is not lost i0 afte.r it has been fitted to the container.
Of course, it is also possible for separate closure elements to be provided instead of a closure element which is connected to the hinged lid. Furthermore, 15 without departing from the scope of the invention, it is conceivable to use all possible closure options, e.g. a closure element which is secured to the closure body by a snap.-action mechanism or a screw thread.
20 The invention is described in more detail below with reference to a diagrammatic drawing of exemplary embodiments of a dispensing closure. In the drawing:
fig. 1 shows an opened dispensing closure in the form 25 of a center longitudinal section;
fig. 2 shows a second embodiment of a dispensing closure in the form of a center longitudinal section as in fig. 1;
fig. 3 shows a third embodiment of a dispensing closure in the same form of illustration as in figs. 1 and 2;
fig. 4 shows a fourth embodiment of a dispensing closure in the same form of i l 1 ustration as i n figs. 1 - 3; and fig. 5 shows a three-dimensional illustration of the dispensing closure from fig. 4.
Fig. 1 shows a dispensing closure 10 for containers which contain free-flowing substances, having a closure body 100 and a closure element 200 designed as a lid.
The closure body 100 and the closure element 200 are connected to one another on one side by means of a hinge 290, which is designed as an integral hinge, so that the closure element 200 can be pivoted through 180 , about an axis formed by the integral hinge 290, from the position in which it opens up the closure body as shown in fig. 1 into the position in which it closes the closure body.
On its top side, the closure body 100 has a cover 120, from the radially outer edge of which a casing 110 extends laterally. The casing 110 is of substantially cylindrical design and has an internal screw thread 112, by means of which it can be screwed onto a container (not shown) having a corresponding mating screw thread and can thereby be secured in place.
As an alternative to the screw connection, it is also possible to provide other ways of securing the closure body on a container, e.g. snap-action connections. It is also possible for the dispensing closure to be formed directly integrally with a corresponding container.
In the embodiment shown in fig. 1, in the upper region of the casing 110 of the closure body 100, in the vicinity of the outer edge of the cover 120 of the closure body 100, there is a sealing lip 114 which is designed in the form of a ring which slopes downward slightly with respect to the horizontal, so that this sealing lip 114, when the closure element 100 is being screwed onto the container, presses onto and seals a top side of the container opening.
In the embodiment shown here, the sealing lip 114 is formed integrally with the closure body but consists of a soft material, in this case silicone, unlike the hard plastic from which the closure body 100 and also the closure element 200 of the dispensing closure 10 are made. However, at this point it should be noted that in another embodiment the sealing lip 114 may be made from the same material as the closure body 100, which simplifies the production process.
The cover of the closure body 100 has a substantially horizontal annular shoulder 122, from which a radially inner region, with respect to the longitudinal center axis, extends outward beyond the annular shoulder in the style of a dome and in stepped form, the diameter of the dome-like elevation 124 being stepped over its height, and the dome-like elevation 124 having an outlet opening 126 at its outer end.
The dome-like elevation substantially comprises a first (or upper) step 128, which, with respect to the cover 120, lies above a second (or lower) step 134. Each of the steps 128, 134 is substantially cylindrical in form, with the two steps 128, 134 having similar heights, but the first step 128 having a smaller diameter. The transitions between the first step 128 and the second step 134 and between the second step 134 and the annular shoulder 122 on the outer side are rounded, so that there are no sharp edges. Above the first step 128 there is a termination rim 136 of the outlet opening 126 which is bent off radially inward and in its top region runs virtually horizontally.
The inner region of the dome-like elevation 124 of the cover 120 is also stepped: beneath the smallest internal diameter of the outlet opening 126 within the dome-like elevation, the internal diameter of the dome-like elevation widens out in the downward or inward direction. After a first widening of the internal diameter directly beneath the termination rim 136, the inner region extends substantially cylindrically over the entire axial extent (in the direction of the height) of the first step and widens out further approximately at the height of the transition region between the first step 128 and the second step 134.
The lower end of the first step 128 of the flexible tube holder 180, in the inner region, forms an annular stop face 130, which at the same time delimits an annular groove 132 in the upper region within the second step 134. The inner region of the second step 134 below the annular groove 132 has a frustoconical profile and widens out downward, merging at its bottom end into the lower side of the horizontally positioned annular shoulder 122 of the cover 120.
The closure element 200 is substantially designed in the form of a lid and comprises a head plate 210 and a side region 220 which extends from the head plate, the side region 220 substantially being designed in such a way that, in a closed position of the closure element 200, it is substantially flush with the casing 110 of the closure body 100.
Furthermore, on its opposite side from the hinge 290, the closure element 200 has a groove 260 for receiving a quality assurance element 160, the groove 260 (in the lower region in the position of the closure element 200 shown in Figure 1, and therefore in the upper region in the closed position) being recessed inward, so that the quality assurance element 160 can be pressed into this recessed region in order to break the seal. The groove 260 for the quality assurance element 160 is delimited by a lug 262 and a protuberance 264 in its upper and lower regions.
The embodiment shown in fig. 1 has a sleeve element 150 which consists of thermoplastic polyester (TPE), extends substantially over the entire outer region of the dome-like elevation 124 of the cover 120 and follows the contour of the dome-like elevation 124.
The dimensions of the sleeve element 150 made from thermoplastic polyester and of the dome-like elevation 124 and a pinch member 280, which is provided on the inner side of the head plate 210 of the closure element 200 and is substantially circular in design, are matched to one another in such a way that, when the closure element 200 is closed virtually without any noise, the pinch member 280 engages over the first step 128 of the dome-like elevation 124 with the sleeve element 150 arranged thereon, and in this way closes off the outlet opening 126 in a sealed manner with respect to the outside.
In the embodiment shown in fig. 1, the external diameter of the sleeve element 150, at the height of the first step 128, in its uncompressed state is slightly larger than the internal diameter of the circular pinch member 280 of the closure element 200, so that as a result of the closure element 200, which is designed as a hinged lid, being closed, with the sleeve element 150 being slightly compressed at the same time, a press fit is produced between the pinch member 280 and sleeve element 150, which leads to reliable sealing at this location, even if minor manufacturing tolerances in the geometry and/or dimensions of the individual elements are present, which is inevitable at least to a small extent, in particular in the case of mass production or else relatively expensive production processes will be required in order to comply with more accurate tolerance requirements.
Purely for the sake of completeness, it should be noted that the embodiment of the dispensing closure shown in fig. 1 is designed in such a way that it is additionally also possible for a flexible dispensing tube to be inserted into the inner region of the closure body 200, which flexible dispensing tube is fixed securely in the inner region of the dome-like elevation 124, with its outer end projecting out of the outlet opening 126, in order if necessary to make it even easier for the free-flowing substances to be removed.
Fig. 2 shows a further embodiment of a dispensing closure, which is substantially identical to the embodiment shown in fig. 1.
Unlike in the embodiment shown in fig. 1, however, the sleeve element 150 is designed in such a way that it covers only an upper region of the dome-like elevation 124, namely the first step 128 and the transition between the first step 128 and the second step 134 of the dome-like elevation 124. Furthermore, in this embodiment the sleeve element 150 is made from a low-density polyethylene (LDPE).
In the embodiment shown in fig. 3, a dispensing closure is designed substantially in the same way as in the embodiment shown in fig. 1. However, the outlet opening 126 in the top side of the closure body 100 is provided with a tamperproof closure 300. This tamperproof closure 300 forms an integral part of the dispensing closure 10 and for this purpose is made from the relatively soft material of the sleeve element 150. A
weakened line 302, which follows the edge of the outlet opening 126 in the dome-like elevation 124, connects the tamperproof closure 300 which seals off the outlet opening 126 to the sleeve element 150. It is advantageous for a tear-off tab 304 to be connected to the tamperproof closure 300 and preferably to be formed integrally therewith. The tear-off tab 304 makes it easy to open the container by tearing off the tear-off tab 304 even if this cannot be done by hand, as is the case, for example, in cycling races or the like.
The tamperproof element 300 therefore ensures that air or oxygen cannot adversely affect the quality of the contents of the container until the container or bottle is opened for the first time. In this case too, the sleeve element 150 together with the tamperproof closure 300 may consist of thermoplastic polyester (TPE) and/or of low-density polyethylene (LDPE), or of rubber, silicone and/or a soft plastic or a combination of these materials.
The embodiment of a dispensing closure 10 shown in fig. 4 differs from that shown in fig. 3 only through the fact that a tamperproof closure 400 is made from the material of the closure body 100 and is produced together with the latter as an integral workpiece using the plastics injection-molding process. This tamperproof closure 400 is exposed at the top or outside and is connected or produced integrally with the closure body 100 by a weakened line 402 which follows the annular edge of the outlet opening 126. A
tear-off tab 404, which as in fig. 3 projects obliquely from the top side of the tamperproof closure 400, consists of the same material as the closure body 100 and is intended to facilitate opening of the container provided with the dispensing closure 10 but to ensure that the quality of the contents of the container is preserved until it is opened by hermetically sealing the outlet opening 126 of the container. The closure body 100 is produced integrally with the tear-off tab 404, preferably from polypropylene (PP) or polyethylene (PE) using the injection-molding process.
Of course, if necessary it is also possible for the tamperproofing means 400, which consists of the material of the closure body 100, and its tear-off tab 404 additionally to be covered with the soft material of the sleeve element 150, in particular if a container equipped therewith is to be used for a purpose in which the container cannot be opened by hand or can only be opened by hand with difficulty, as is the case in certain forms of sport, such as for example cycling etc.
Fig. 5 gives a general impression of the described dispensing closure from figs. 3 and 4, with the dispensing closures shown in figs. 1 and 2 also being comparable to the illustration of the dispensing closure provided in fig. 5 if one imagines that the tamperproof closure 400 and the tear-off tab 404 are absent, and instead there is an open outlet opening 126 of the closure body 100.
