Definitions
- the invention relates to a closure cap with an outlet connection piece, which can be opened and closed by displacing a telescopic part along a central axis of the closure and has a mouth portion, the telescopic part being displaceable on the connection piece while guided on the outside thereof, the closed position being latched and a closure stopper being provided, molded onto the telescopic part by means of cross-pieces leaving throughflow openings.

- the throughflow openings are also effectively closed by the end face of the connection piece extending under them. It could even be provided that the end face protrudes into the throughflow openings by corresponding elevations.

- the end face of the telescopic part is substantially closed, in particular when a drink is taken directly from the closure cap.
- the mouth portion has a mouth funnel.
- the mouth funnel serves for receiving and introducing the closure stopper during the movement from the open position into the closed position.
- This mouth funnel may be configured in such a way that it is made to taper toward the container. It correspondingly tapers from the outside inward.

Abstract
Description
- The invention relates to a closure cap with an outlet connection piece, which can be opened and closed by displacing a telescopic part along a central axis of the closure and has a mouth portion, the telescopic part being displaceable on the connection piece while guided on the outside thereof, the closed position being latched and a closure stopper being provided, molded onto the telescopic part by means of cross-pieces leaving throughflow openings.
- Closure caps of this kind, which may be screwed or press-fitted onto an associated container or connected to the container in some other way, are known in various embodiments. Reference is made for example to
EP 1 065 150 A1. - Even if such closure caps have proven successful in principle and are widely encountered, there is still a need to configure such a closure cap in a way enhancing its functional features but not requiring any significant additional expenditure, for instance with regard to a molding tool required.
- This object is achieved in the case of the subject matter of
Claim 1 of the present application first and foremost by providing that the closure stopper latching in the mouth portion is molded on by means of cross-pieces that run in superposed alignment with an end face of the connection piece. - It is important that the latching in the mouthpiece portion of the connection piece is realized by the closure stopper. The fact that the connection of the closure stopper is provided by cross-pieces that reach over the end face of the connection piece, or at least run in superposed alignment with it, means that the telescopic part is formed substantially as a cup with throughflow openings formed in the base. As a result, a relatively large opening area can be realized overall. Depending on the configuration, in the closed state the throughflow openings are also effectively closed by the end face of the connection piece extending under them. It could even be provided that the end face protrudes into the throughflow openings by corresponding elevations. With regard to the comparison mentioned, the cup is slipped over the connection piece from above with the cup opening facing downward. Emptying in the opened state is also advantageous. The liquid leaving the container through the mouth can flow around the closure stopper and come out through the throughflow openings. Some of the throughflow openings may also be used at the same time for allowing air to enter. On the other hand, the end face of the telescopic part is substantially closed, in particular when a drink is taken directly from the closure cap.
- The further claims represent advantageous configurations of the teaching presented in
Claim 1, but may also respectively be of importance in their independent formulation. - Firstly, it is preferred that the mouth portion has a mouth funnel. The mouth funnel serves for receiving and introducing the closure stopper during the movement from the open position into the closed position. However, it is also advantageous with respect to running-out characteristics. This mouth funnel may be configured in such a way that it is made to taper toward the container. It correspondingly tapers from the outside inward. To this extent it is preferred that the mouth funnel is formed on the outer edge of the mouth, said outer edge forming the said end face, by means of its region of larger diameter. The mouth funnel is correspondingly provided in such a way that it is rotationally symmetrical in relation to a central axis of the closure cap.
- It is also preferred that the said mouth portion has a latching portion, which in the closed state engages behind a corresponding latching formation of the closure stopper. For this purpose, it is further preferred that the closure stopper is formed with a corresponding configuration. In the closed state, a lower edge of the closure stopper protrudes beyond the lower edge of the mouth portion or of the funnel.
- Together with the cross-pieces and a peripheral edge portion, which preferably also runs out into a projecting gripping edge, the upper or outer surface of the closure stopper forms a virtually planar end face. This is technically advantageous with respect to cleaning and at the same time also pleasant when it is used as a drinking closure. The openings between the cross-pieces are preferably of such a size that it is virtually impossible for the tongue to penetrate.
- It is also preferred that, in the closed state, a cavity remains between an inner surface of the cross-pieces, or regions adjoining them, or at least adjoining or further regions of the telescopic part, and the associated end face of the connection piece. This is so because it has been found that, when this closure is used as a drinking closure on a bottle, which is the entirely customary way in which it is used, residues of liquid are deposited on the shoulder of the connection piece, for instance in the form of drops, in the open state. If the telescopic part is then pressed downward, to close the bottle, these residues of liquid are displaced and may even be squirted out. The said cavity, which is adapted to the quantity of the residues of liquid collecting there, prevents such occurrences. On account of the openings between the cross-pieces, which also remain in the closed state, such residues of liquid can then readily dry out however. On account of the surface tension, it is even unlikely for them to drip out if such a bottle happens to fall over.
- With regard to the telescopic part, a special configuration is also obtained by the cross-pieces extending obliquely downward, as seen from the outer edge. In other words, in the case of this configuration the cross-pieces have an obliquely upward and outward extent, with respect to a horizontal line, starting from their radially inner region of attachment to the closure stopper. Therefore, the openings do not lie directly freely in the end face but are as it were formed in a funnel area. The angle with respect to the horizontal may vary. It is preferably an acute angle in the range from 5 to 85°. In principle, however, a right angle is also possible, whereby the openings then extend virtually in a cylindrical area.
- A special measure also provides that lugs are formed in the end face of the connection piece in such a way that they are distributed and spaced apart from one another and are associated with a radially outer edge of the end face. These lugs may even be formed as spring elements, for instance by means of a certain undercut. This produces a punctiform support for the telescopic part on the connection piece in the closed state and possibly a certain pretensioning in the latching, which can contribute to even better sealing of the latching.
- The invention is further explained below on the basis of the accompanying drawing, which however merely represents one exemplary embodiment. In the drawing:

FIG. 14 shows a plan view of the subject matter according toFIG. 12 ; -
FIG. 15 shows a further modified embodiment in a representation according toFIG. 1 orFIG. 9 : -
FIG. 16 shows the subject matter according toFIG. 15 , after removal of the overcap, in the open state; -
FIG. 17 shows a perspective representation of the telescopic part in the case of a subject matter according toFIG. 15 orFIG. 16 . - Represented and described, first with reference to
FIG. 1 , is aclosure 1 produced by the plastics injection-molding process, which, for attachment to a container, is formed in the lower region with ascrew portion 2, on which atamperproof strip 3 is formed further down. - The
screw portion 2 goes over in a step-shaped manner, with step-shaped inward narrowing, into aconnection piece 4 with amouth portion 5. - A
telescopic part 6 is guided on the outside of theconnection piece 4. Formed on thetelescopic part 6 arecross-pieces 8, which leavethroughflow openings 7, cf.FIGS. 5 and 6 , and go over into acentral closure stopper 9. - The end face of the
telescopic part 6 is made up of anouter edge portion 21, running around the periphery as a closed ring, and an innerclosed end face 22, formed by the closure stopper, as well as thecross-pieces 8 extending in between. Theedge portion 21 is extended into anoverhanging gripping portion 23. As illustrated in further detail inFIG. 2 , for instance, it is preferred that, up to atransition 24 formed in the region of theclosure stopper 9, the end face rises to aconcave area 25, and then goes over into the centralconcave area 25 of the closure stopper. The angle of the rising area with respect to a horizontal line is small. It is an acute angle of a few degrees, for instance in the range from 1 to 15°. - The
cross-pieces 8 run in superposed alignment with anend face 11′ of theconnection piece 4. The end face 11′ is made up specifically of the area component of theouter edge 11 and the area component of thefunnel portion 10. In the case of the exemplary embodiment, thecross-pieces 8 respectively reach over both area components—even if not completely (in cross section). - As
FIG. 2 also illustrates in greater detail, in the closed state theclosure stopper 9 is latched in themouth 5. - To be specific, the
mouth portion 5 forms afunnel portion 10, which goes over integrally with its region of larger diameter into anouter edge 11 on the end face of the mouth or theconnection piece 4. Thefunnel part 10, which tapers approximately at an angle of 45° in relation to its perpendicular central axis and correspondingly tapers toward the container, goes over in its portion of smallest diameter into avertical portion 12. Thisvertical portion 12 is at the same time used for the latching with theclosure stopper 9. This is so because theclosure stopper 9 has avertical portion 13 of corresponding diameter and shape, which is exceeded in terms of diameter on the underside by anedge bead 14. On the upper side, the latchingregion 13 goes over via a wideningportion 15 into atop stopper face 16. - Therefore, in the closed state the
telescopic part 6 is latched by means of the latching portions of themouth portion 5 and of theclosure stopper 9. - If desired, a means of latching in the open state may also be formed on the outer surface of the
connection piece 4, in the region where thetelescopic part 6 interacts with themouth portion 5. However, this is not the case in the exemplary embodiment. - The
overcap 17, which can be seen inFIG. 1 and engages over the unit comprising theconnection piece 4 and thetelescopic part 6 in the closed state and, before being used for the first time, with a tamperproof seal provided by means of atamperproof ring 18, is for its part also secured by latching on theconnection piece 4. This is accomplished by interacting projections and recesses 19, 20 in the first step portion of theconnection piece 4. - The
overcap 17 only fits in a latching manner onto theconnection piece 4 when theclosure stopper 9 is in the closed position according toFIG. 2 . - It is evident from the representations of
FIGS. 3 and 4 that theclosure stopper 9 is formed with such an extent into the interior with respect to thetelescopic part 6, and thefunnel portion 10 with such an extent toward the container, that, in the open state, as it is represented inFIGS. 3 and 4 , a lower edge of theclosure stopper 9 finishes approximately in line with the outer edge of the mouth. Theclosure stopper 9 itself is formed as a cup, with a cup base curved toward the interior of the container and, at the bottom of the cup, leg regions formed from thicker material and curving radially outward. These leg regions, or the wall of the cup, at the same time form the sealing and latching portion of theclosure stopper 9. - As
FIGS. 5 and 6 show in detail with respect to thetelescopic part 6, a multiplicity ofthroughflow openings 7 are formed, to be specific in the case of the exemplary embodiment eightthroughflow openings 7. This makes smooth emptying or drinking possible, one or more of the openings also being able to be used at the same time to allow air to enter. - In the case of the embodiment of
FIGS. 7 and 8 , the lower fitting region of theclosure cap 1 is, as already mentioned, formed in a narrowed manner. This correspondingly produces only a configuration of slightly smaller diameter of the lower edge of theovercap 17, and consequently also of thetamperproof ring 18 formed on theovercap 17, with respect to the edge formed on the underside of the cap or thetamperproof ring 18 formed on it. - A modified embodiment is represented with reference to FIGS. 9 to 13 of the drawing.
- The modifications primarily concern the associated regions, at the end face, of the
telescopic part 6 and of theconnection piece 4. - As illustrated by
FIG. 9 , but in particular also by the enlargement according toFIG. 10 , between aninner surface 26 of thecross-pieces 8, of theedge portion 21 and of theclosure stopper 9 there is a distance a from theend face 11′ of theconnection piece 4, which results in acavity 28 which is also present specifically in the closed state. It is evident that the distance a is formed such that it changes in the radial direction, to be specific in the case of the exemplary embodiment increasing radially inward. However, there is also an initially constant smaller radial distance a in the region of theshoulder 29 of theconnection piece 4 and the associatedface 26 of thetelescopic part 6. - Any residues of liquid that may be deposited in this region in the open state consequently also find sufficient space in the closed state, so that they are not for instance squeezed out in the course of closing.
- The distance a is in each case also provided in an encircling manner. In the case of the exemplary embodiment, therefore, the cavity is produced as a corresponding annular space, only interrupted by the
lugs 27 in the region of thestep face 29. - The
lugs 27 are formed in theend face 11′ in the radially outer region, to be specific in the case of the exemplary embodiment in the region of the mentionedstep face 29 of theconnection piece 4. As is to be gathered fromFIG. 10 , in the closed state they maintain a spacing between thetelescopic part 6 and theconnection piece 4 also in this region, in the sense of the distance a in the vertical direction. They may also be resiliently formed, so that they contribute to the sealing closure between the latchingbead 14 of theclosure stopper 9 and the associatedvertical portion 12, or specifically themating face 12′ coming into contact with the latchingbead 14. - The
funnel portion 10 has arib formation 30, which is moreover elevated above theend face 11, of thefunnel 10. Starting from the upper, radially outer region of thefunnel 10, thisrib 30 is formed such that it extends radially inward. In the case of the exemplary embodiment, however, it ends at a distance before thevertical portion 13 of theclosure stopper 9. Preferably, such a rib is only formed once over the circumference. It may be used for instance for orientation during assembly, if required in an individual case. As can also be gathered for instance fromFIG. 14 , the width of the rib corresponds approximately to two to three times the width of across-piece 8 between twothroughflow openings 7. - As further illustrated for instance by the representation of a detail in
FIG. 11 , in the exemplary embodiment described theovercap 17 is formed in the first step portion of theconnection piece 4 with aperipheral latching groove 31, which interacts with acorresponding latching bead 32, formed on the perpendicular face of the first step portion of theconnection piece 4. - Further provided in the
second step portion 33 of theconnection piece 4 aretamperproof formations 34, in which thetamperproof ring 35 correspondingly engages, which leads to shearing off in theregion 36 when theovercap 17 is removed for the first time. - The representations of
FIGS. 12 and 13 also illustrate that the telescopic part is raised in the open state to the extent that a lower edge of theclosure stopper 9 extends approximately at the height of theend face 11, at the outer edge of theconnection piece 4, in the case of the detail ofFIG. 12 at the height of thelugs 27. A corresponding opening displacement is also obtained in the case of the first exemplary embodiment, as described above. - The embodiment of FIGS. 15 to 17 differs from the previously described embodiments in the main in that the
throughflow openings 7 or thecross-pieces 8 forming them are shaped in such a way that a funnel-like extent of the telescopic part, widening radially outward, is obtained in this region. - With respect to a horizontal line H, the
throughflow openings 7 that can be seen inFIGS. 15 and 16 , or thecross-pieces 8 forming them, run upward, in the case of the exemplary embodiment with a relatively small acute angle α of about 10 to 15°. It is not required here that theopenings 7 or thecross-pieces 8 run in a way corresponding to a straight line. They may, for example, also run in a way corresponding to a curved line. In the case of the exemplary embodiment, furthermore, the end face of theclosure stopper 9 is incorporated by continuous continuation into the concave formation thereby achieved overall. As a departure from this, an opposite convex formation may be formed for instance in the region of theclosure stopper 9. - As illustrated by the perspective representation of
FIG. 17 , this also contributes to a reduction in the apparent size of thethroughflow openings 7 in the outer appearance. - The radial width of a
throughflow opening 7 may be provided preferably in the range from 1 to 3 mm, more preferably it may be 2 mm. The peripheral width of athroughflow opening 7, see alsoFIG. 14 for the second embodiment orFIG. 5 for the first embodiment, may be 1.5 to three times its radial extent. - All disclosed features are (in themselves) pertinent to the invention. The disclosure content of the associated/accompanying priority documents (copy of the prior patent application) is also hereby incorporated in full in the disclosure of the application, including for the purpose of incorporating features of these documents in claims of the present application.
