    description
    The invention relates to a device for receiving or removing liquid, for example by drinking, with a pot-shaped, oval in cross-section mouthpiece made of plastic, which has a shell and a bottom, wherein in the bottom along the short oval axis a parting line extends, in which in Schließsteliung two sealing surfaces abut each other. According to the invention, the two sealing surfaces are moved away from each other by compressing the mouthpiece along the short oval axis and the parting line widens to an opening. Liquid flows from the interior of the cup-like part through the opening in the bottom to the outside.
    Devices of this type are shown in US 2002092877 A1, EP 1 017 618 B1, US Pat. No. 6,279,772 B1, WO 2010/028413 A2 and, in batches, also GB 2 279 130 A.
    According to US 20020092877 A1, the bottom of the pot-like part is curved inwards. Along the sealing surfaces, the wall thickness of the floor is reinforced by a projecting on the outside of the floor web. The shell of the pot-like part is formed at the peripheral regions between which the largest width of the cup-shaped part is formed over its entire length with greater wall thickness than the bottom and he is also formed with greater wall thickness than at the peripheral regions between which the smallest width is included ,
    According to EP 1 017 618 B1, the bottom of the pot-like part is arched to the outside. The shell of the pot-like part is formed at the areas of greatest width of the pot-like part over its entire length with greater wall thickness than the bottom. In regions lying away from the ground, the wall thickness of these jacket regions is increased again in relation to the jacket regions closer to the bottom. In a construction variant, along the sealing surfaces, the wall thickness of the floor is reinforced by a web projecting on the inside of the floor. In another construction variant, the inside of the floor surface is curved inward, although the outside of the floor is curved outward.
    According to GB 2 279 130 A, the lateral surface of the pot-like part is circular symmetrical and not oval. The bottom surface has consistently constant thickness and is curved inwards. The lateral surface and the bottom surface have approximately the same wall thickness. Only in areas of the lateral surface, which are far away from the bottom surface, the wall thickness is increased.
    In the US 6,279,772 B1, the bottom part is flat on the inside and convex on the outside. On the inside of the bottom run parallel to the parting line groove-like depressions. * W947
    In the device according to WO 2010/028413 A2, the wall thickness of the jacket is greater at the longitudinal area adjacent to the floor than at the longitudinal area spaced from the floor. At the transition region to the bottom of the cup-like part in the peripheral region at the two ends of the short oval axis each have a radially outwardly directed thickening. Except for these thickenings, the wall thickness of the shell in the longitudinal region adjoining the bottom at the end regions of the long oval axis is greater than that of the short oval axis. The bottom of the pot-like part is curved inwards and reinforced by a protruding on the inside of the bottom, along the short oval axis extending web, in which the parting line runs, so that it is divided into two lips. Compared to the above-mentioned constructions, the combination of these features, despite the use of simpler material for the device equal good or better tightness can be achieved.
    The object underlying the invention is to further improve the known from WO 2010/028413 A2 device for receiving or removing liquid, so that it is reliably tight at even higher internal pressures, yet comfortable to open according to its intended purpose and yet off may be formed thermoplastic elastomer.
    To solve the problem is assumed by a device as mentioned above, which has a mouthpiece, which is formed as a pot-like, in cross-section oval part made of plastic, which has a jacket and a bottom, wherein in the bottom along the short oval axis, a parting line, at which two sealing surfaces abut each other in the closed position. The bottom of the pot-like part is curved inward and reinforced on its inside by a running in the short oval axis web, which is divided into two parts in its longitudinal direction by the parting line. According to the invention, the two lateral lateral surface sides of the web can be transitioned into in each case one side surface of in each case one groove, which runs parallel to the web on the inside of the bottom.
    In a preferred embodiment, the upper lateral surface side of the web is provided with two ribs protruding therefrom, which enclose the parting line between them.
    In a further preferred embodiment, the distance between the two ribs decreases with the distance to the longitudinal center of the web.
    The invention will be illustrated with reference to five drawings to two preferred embodiments:
    Fig. 1: shows an exemplary device according to the invention in a perspective sectional view. The cutting plane is the plane of symmetry normal to the plane of the parting line through the device.

    Fig. 2: shows the device of Fig. 1 as viewed normal to the ground in the pot-like part inside.
    3 shows a further sectional view of the device of FIGS. 1 and 2, wherein the sectional plane is the plane of the parting line.
    Fig. 4: shows a variant of the device of Fig. 1 as viewed normal to the ground in the pot-like part inside.
    Fig. 5: shows a detail of the device of Fig. 3 in a perspective sectional view.
    In the example shown, the cup-like part 1 of the device according to the invention consisting of bottom 1.1 and jacket 1.2, 1.3 has a ring-like extension 3 on the side of the jacket facing away from the bottom, by means of which it protrudes at the edge of an opening in a surface 10 (FIG ), which is typically part of a larger container such as a beverage bottle or part of the top surface of a screw cap.
    In extension 3, a vent valve 4 designed as a check valve can be arranged, through which air can flow into a rigid container when liquid flows through the parting line as intended. For reasons of durability of the liquid, it is better to use a collapsible or otherwise somehow volume reducible container, typically a bag, instead of a rigid container and not provide a vent valve 4 - which is easily possible within the scope of the invention. By then the volume of the container during the liquid core withdrawal can decrease by the volume of the withdrawn liquid, no air needs to get into the container. As a result, no germs are brought into the container and it does not come to oxidation of the liquid.
    Instead of widening the device at its end facing away from the bottom as shown for use at an opening of a wider area 10, one could also rejuvenate it there for connection to a narrower hose or straw.
    As can be clearly seen in FIG. 1 and in FIG. 3, the lateral surface of the cup-shaped part has essentially two longitudinal regions, which differ from one another by different wall thicknesses. From the bottom 1.1 to about half of the length of the shell extends the longitudinal region 1.2, which has substantially greater wall thickness than the side facing away from the bottom 1.1 longitudinal region 1.3. The transition between the two wall thickness ranges is ideally fluid, as illustrated, and not abrupt.
    However, the longitudinal region 1.2 of the lateral surface in itself does not have the same wall thickness throughout. 1 is a sectional view in which the cut surface is parallel to the longitudinal
    Page 3 • * • »W947 oval axis passes through the cup-shaped part 1. The visible wall thickness "a " the lateral surface in the longitudinal region 1.2 at those two peripheral regions of the lateral surface which enclose between them the largest width of the cup-shaped part 1, is greater than the visible in Fig. 3 wall thickness "b" of circumferentially offset by a quarter turn lateral surface parts, which between them the smallest Include width of the cup-shaped part 1. Ideally, the transitions of the wall thicknesses between the values a and b over the circumferential course of the lateral surface parts 1.2 are fluid and not abrupt.
    Ideally, the wall thicknesses shown a and b, which represent extreme values of the wall thickness of the lateral surface in the longitudinal region 1.2, greater than the wall thickness of the bottom surface 1.1 -with the exception of that part of the bottom surface to which this is reinforced by the web 1.5. The total height of web and bottom surface 1.1 should be about the same as the wall thickness a at the bottom part of the lateral surface at the ends of the long oval axis.
    Only at the transition region to the bottom 1.1 of the cup-shaped part, the lateral surface of the cup-shaped part in the region of the two ends of the short oval axis in each case a radially outwardly directed thickening 1.4 (FIG. 3).
    The bottom 1.1 is stiffened on its inside by a web extending along the short oval axis, protruding from the bottom surface web 1.5, wherein the parting line 2 extends in this web 1.5, so the web has a longitudinal slot and is divided by this in two lips, which at undeformed device as two flat contact surfaces lie flat against each other. The two contact surfaces, which in strongly opened parting line are related only to two boundary lines, are further referred to in this document as "sealing surfaces".
    At its two longitudinal ends of the web is 1.5 in the lateral surface 1.2, wherein the transition is preferably rounded.
    The cross-sectional area of the web 1, 5 is preferably approximately rectangular, wherein the dimension of the height is preferably more than the dimension of half the width but less than the dimension of the entire width. Except for the transitions to the lateral surface, the height and width of the web 1.5 can be constant over the web length, so that the web 1.5 as well as the bottom 1.1 is curved toward the interior of the pot-like part (FIG. 3).
    Ideally, the parting line 2 in the closed state is a flat surface which lies in the plane in which lies the short oval axis of the bottom 1.1 of the cup-shaped part 1 and which is parallel to the direction of the height of the pot-like part. In the example according to FIGS. 1 to 3, the cross-sectional areas of the web 1.5 are mirror-symmetrical to this plane.

    According to the purpose of opening the parting line 2 in the bottom 1.1, the two flatter peripheral regions of the lateral surface 1.2 moves towards each other by the wall portions are moved toward each other with the wall thickness "b" shown in Fig. 3 by external pressure force. For use as an opening for a vessel, said external pressure force is applied through the teeth, lips or fingers. The teeth, lips or fingers can do well at the ends of the short oval axis of the pot at the transitions of the thickenings 1.4 to the "normal" longitudinal region 1.2 of the lateral surface and move these two attack surfaces to each other. The sealing surfaces on the parting line 2 fold at the thus caused deformation of the cup-like part to the outside. For the reliable tightness up to high internal pressures, the shape of the bottom 1.1 and the geometry in the region of the parting line 2 is of importance. The bottom 1.1 must be curved inwards at least on its inside. Internal pressure tends to reduce the curvature of the soil. Since due to the high wall thicknesses of the lateral surface in the region of the edge of the soil, the circumference of the soil can not or hardly be increased, the middle part of the soil is placed under compressive stress with the surface of the soil lying parallel stress component, bringing the sealing surfaces on the Parting line 2 are pressed together. Since the material used is relatively soft elastic and is well deformed in the elastic region, this pressing causes a large-area contact of the sealing surfaces of the parting line 2 and thus a good sealing effect. An important function of the web 1.5 is also to stiffen the bottom 1.1 against buckling outward fluid pressure inside the pot-like part. Because the outer surface of the base is concave-that is, inwardly-curved, the opening between the sealing surfaces can become larger than if the outer surface were convexly curved or flat.
    The sealing effect at the parting line is substantially enhanced by the fact that the height of the web 1.5 is greater than half its width (Fig, 1). By this measure, the two, divided by the parting line 2 halves of the web 1.5 not only pressed by deformation of the bottom 1.1 to each other, but also directly by the ruling in the interior of the cup-shaped part fluid pressure by this parallel to the two parallel to the sealing surfaces Lateral surface sides of web 1.5 presses.
    In Fig. 1 is clearly visible that along each side of the web 1.5 a groove 1.6 extends on the inside of the bottom 1.1. At the bottom of these grooves 1.6, the wall thickness of the bottom 1.1 is only a good half of the wall thickness at more distant from the web 1.5 floor areas. The two lateral lateral surface sides of the web 1.5 go with their lower
    Page 5 »· W947
    Edge seamlessly in each case a flank surface of a groove 1.6 on. Preferably, the width of a groove 1.6 is smaller than half the width of the web 1.5.
    By virtue of the grooves 1.6, the limit of that internal pressure in the cup-shaped part, beyond which the separating gap no longer seals at the top, is markedly increased, namely by approximately 50%, compared to otherwise identical devices without such grooves. Preferably, two spaced apart ribs 1.7 project from the upper lateral surface side of the web 1.5 and extend in the longitudinal direction of the web 1.5. The cross-sectional areas of these ribs 1.7 are significantly narrower and lower than the cross-sectional area of the web 1.5. Preferably, these ribs are not simply parallel to the web 1.5, but so that they have the greatest distance from each other in the longitudinal center of the web and at the transitions to the lateral surface 1.2 the smallest distance. In each case a length half of a ribs 1.7 can be formed as a straight piece of track.
    Preferably take in the longitudinal center of the web 1.5, the two ribs 1.7 and the distance between these two the entire width of the web 1.5 a.
    Preferably, in the vicinity of the ends of the web (1.5), the distance between the two ribs (1.7) including the width of both ribs (1.7) is less than the width of the web (1.5).
    Essentially, the ribs 1.7 cause the parting line, when properly opened, to clear a much larger opening for flow than it would without such ribs.
    In Fig. 4 and Fig. 5 shows a variant of a device according to the invention is shown, wherein the web 1.5 is not equipped as in the previous example with ribs, but is designed asymmetrically. The asymmetry consists in that the two lateral flanks 1.5.1, 1.5.2 of the web 1.5 are formed differently. While the flank 1.5.1 shown on the left runs essentially rectilinearly parallel to the parting line, the flank 1.5.2 shown on the right is slightly concave or bent so that it lies farther away from the parting line 2 at the longitudinal center of the web 1.5 than at the longitudinal areas. which are further away from the longitudinal center of the web 1.5.
    This asymmetry causes the opening on the separator 2 to be asymmetrically formed along the short oval axis as a result of compression of the cup-shaped part. Only the part of the web with the concave flank 1.5.2 is folded outwards. With otherwise identical designs, the opening with asymmetrical web is not as large as symmetrical web. The advantage of the asymmetrical web over the symmetrical web is that reliable sealing is achieved up to higher pressures.

    It has been found that the deformation behavior of the web 1.5 is advantageously influenced during opening and closing of the parting line 2 when the end regions of the flanks of the web 1.5, as shown in FIG. 5, pass over into the wall 1.3 of the pot-like part in such a way as can be seen in FIG the areas closer to the bottom 1.1 have a rounded transition and that the top surface of the web 1.5 is widened so that at the Längsen-the flanks 1,5,1, 1.5,2 of the web are 1.5 corner regions 1.5.3 formed. The formation of such corner regions at the transition from the web to the wall is also advantageous in the case of a symmetrical web, as in the embodiment of FIGS. 1 to 3.
    In an exemplary dimensioning of a device according to the invention which is to be regarded as typical, the diameter of the cup-shaped part is approximately 19 mm in the direction of the longer oval axis and approximately 14 mm in the direction of the shorter oval axis. The further exemplary and typical dimensions can be taken to scale from the drawings Fig. 1 to Fig. 3. As a plastic material for the device, thermoplastic elastomers (TPE) are quite good. They can be well brought by injection molding in the illustrated form. The parting line 2 performing slot can be made by a subsequent cutting process. With the given dimensioning rules and the specified material, the device according to the invention can be manufactured so inexpensively that it can be marketed as a disposable product to be sold together with a beverage. The described geometric specifications for the device, the nonlinear elasticity and deformation properties of the thermoplastic elastomers are intrinsically and make them difficult to unsuitable for many applications, not disturbing.
    However, the device according to the invention can also be produced well from other soft elastic materials than thermoplastic elastomers, in particular from silicone.
    In an advantageous embodiment, the device according to the invention is integrally formed with a screw cap - of which in Fig. 3, the top surface 10 is indicated - and arranged pivotally mounted protective cap. Screw cap and protective cap are ideally made of a stiffer plastic than the device according to the invention. In an advantageous, because simple procedure, to the parts of different material are formed from thermoplastic and joined together by two-component injection molding.
