Description

Field of the Invention

[0001] The present invention relates to a drinking bottle closure with a double sealing function for a drinking bottle, in particular an insulated drinking bottle, having the features of the preamble of claim 1. Background Art

[0002] Such a drinking bottle closure is known from DE 102019128302 B3. This includes a body base member in which a closure unit is arranged. An upper and a lower sealing level are formed by the closure unit, and the lower sealing level represents the main seal against the interior of the drinking bottle, and the upper sealing level prevents liquid residues from dripping out of the cavity of the closure unit even when the drinking bottle equipped with the drinking bottle closure is transported lying flat or inverted.

[0003] Such a closure device has proven itself to be functional and can be manufactured with a small diameter. However, after the user has pre-pressed the button once, a relatively long spring-loaded tongue is provided to independently hold the closed and open positions by means of a ballpoint pen drive unit, resulting in a large overall height. Although the closure unit can be partially positioned within the bottleneck and lowered into the drinking bottle, this results in a loss of the available volume for storing the beverage. However, the long spring tongue has the advantage of firmly holding its position once adopted.

[0004] Other drinking bottle closures are known in which the closure unit provides a rotating star member in a familiar "ballpoint pen drive" manner. However, it has been shown that in the case of impacts and other external influences, an unintentional backward rotation of the star member occurs, i.e., when the user drinks from the bottle, the star member inadvertently returns from the open position to the closed position.

[0005] Furthermore, for insulated stainless steel drinking bottles with an internal thread, there is the problem that when hot beverages are poured in, the bottleneck becomes hot and then, when it cools, the bottleneck shrinks onto the subsequently inserted drinking bottle closure, making it sometimes difficult to disconnect the connection between the drinking bottle and the drinking bottle closure. Summary of the Invention

[0006] Therefore, the object of the present invention is to improve a drinking bottle closure of the above type such that the overall height is reduced, the open and closed positions are firmly held, and the connection to the drinking bottle can be easily released.

[0007] These objects are solved by a drinking bottle closure with a double sealing function for a drinking bottle having the features of claim 1.

[0008] The drinking bottle closure of the present invention includes a body base member in which a closure unit is provided, and a releasable connection is preferably provided by means of a thread or a bayonet fit to facilitate cleaning of the drinking bottle closure.

[0009] As is known per se, upper and lower sealing levels are formed by the closure unit, so that even when the drinking bottle equipped with the drinking bottle closure is transported lying down or inverted, liquid residues can be prevented from dripping out of the cavity of the closure unit. The ballpoint pen drive unit ensures that firmly defined open and closed positions are adopted and maintained.

[0010] The main advantage of the present invention is that, since only the intended rotational direction of the central star member that controls the stroke movement of the sealing plate in the button unit is possible, and in each case rotation can be achieved only by the firm pressure of the user on the button and not accidentally by external influences, the safety in the closed position is increased.

[0011] For this purpose, the present invention provides that the circumferential region on the star member outside the tooth profile required for the lifting and lowering movement has a special cross-sectional profile. The cross-section includes at least one check profile having a stop edge that jumps suddenly inwards, before which the spring-mounted pin slides along a region that widens radially outwards along the circumference in a manner similar to a rising ramp and gradually deflects outwards as the star member rotates, and then the spring-mounted pin rebounds again behind the contact edge and abuts against the stop edge.

[0012] The spring-mounted pin that scans the locking profile additionally provided on the star member can be the same as that required for scanning the tooth profile.

[0013] In addition to the fixed pins that only scan the tooth profile, at least one spring-mounted pin can be provided that is only used for interacting with the circumferential locking profile.

[0014] Preferably, the spring-mounted pin is also suitable for scanning the tooth profile and the locking profile around the circumference.

[0015] Preferably, two sets of pins are provided that project radially inwards into the receiving recess and scan the tooth profile of the star member, the first set including fixed pins and the second set including radially spring-mounted pins. In particular, the fixed pins that only scan the raised tooth profile of the star member do not project as far radially into the receiving recess as the spring-mounted pins that scan the axially extending raised tooth profile and the circumferential locking profile.

[0016] In the case of multiple sets, all the pins should be arranged at equal intervals along the circumference of the receiving recess, with the fixed pins and the movable pins arranged in an alternating order. In the case where each of the two sets has two pins, this results in similar pins being diametrically opposite. Even with different numbers of pins, it is also advantageous if at least two movable pins are arranged radially opposite each other.

[0017] Regarding an arrangement with a uniform spacing of preferred diameters relative to each other, it is preferred to form a corresponding number of uniformly spaced stop profile portions on the star member. In this way, at least two movable pins are always fixed to the stop profile simultaneously.

[0018] Preferably, the star member has an upper and a lower raised tooth profile, wherein the stop profile is formed between the tooth profiles on the periphery of the star member. The fact that the pins are guided axially between the two tooth profiles means that both the open position and the closed position can be defined more precisely compared to a ballpoint pen drive unit having only one tooth profile. The desired open and closed positions are determined by one tooth profile, and during rotation of the star member, the pins are guided by the other tooth profile and brought to a position near the desired position on the corresponding other tooth profile.

[0019] Preferably, the star member is divided into a lower and an upper part, whereby these parts can in particular be latched together. This facilitates assembly, especially when the star member has two tooth profiles: when assembling the star member, the lower and upper parts are guided into the recesses in the control base member from different sides such that the pins are positioned between them in the area of the stop profile. Then these parts are joined together.

[0020] At least in the case where a detachable connection is provided between the body base member and the closure unit by means of a thread, the diameter of the button must be smaller than the diameter of the pouring opening. In this case, the button must be reduced in diameter to such an extent that it can pass through the thread provided for the connection. On the other hand, the button together with the intermediate housing member connected to it is only held against the control base member by means of a compression spring. Thus, there is no lateral guidance, such that the button can be tilted. Therefore, it is particularly advantageous to construct at least three guide tabs on the inner wall of the pouring opening to guide the button. By means of at least three axially extending tabs, good lateral guidance can be achieved in a simple manner and tilting can be significantly reduced. The thickness or radial extension dimension of the additional guide tabs relative to the inner wall of the pouring opening should be at least equivalent to the thickness of the thread tabs for connection to the detachable closure unit. Since the closure unit is inserted into the body base member from below, the guide plate can also have a greater thickness than the thread; during use, only wear - resistant contact of the guide tabs with the outer edge of the button should be avoided.

[0036] Figure 1A perspective view of a drinking bottle 101 with an attached drinking bottle closure 100 is shown. The drinking bottle closure 100 includes a body base member 50 having a protruding pouring edge 51 around a pouring opening 52. The protruding pouring edge 51 can rest on the lips for drinking directly from the drinking bottle 101. A closure unit 1 is inserted into the pouring opening 52, where only the button 10 is visible, and the button simultaneously represents an upper sealing element that, in the closed state, rests on a resilient body sealing lip 53 around the pouring opening 52, and the resilient body sealing lip forms an upper sealing plane together with the button 10 as the upper sealing element.

[0037] In Figure 2 a perspective cutaway view shows the drinking bottle closure 100 with the closure unit 1 removed from the body base member 50. At the upper edge, the sealing lip 53 extends into the pouring opening 52.

[0038] The body base member 50 is designed as a multi-component plastic injection molding. The cylindrical pouring opening 52 is defined by the wall of an insert 54.

[0039] On the insert 54, a receiving area for a neck thread 56 as an internal thread is formed to receive a neck with an external thread and tightly connect it to the drinking bottle closure 100. To seal this connection, a resilient washer 59 is overmolded at the upper end of the receiving area.

[0040] A thread 55 is formed on the inner circumference of the wall through which the closure unit 1 is received with an external thread 39. To connect the closure unit 1 to or disassemble it from the body base member 50, two wings 62 are formed on the lower sealing element 60 of the closure unit 1. The closure unit 1 can be rotated thereon. Since all components are exposed, the removed closure unit 1 can be easily cleaned.

[0041] While the button 10 also serves as the upper sealing element that abuts the upper sealing lip 53 from below in the closed state, the lower edge of the cylindrical wall of the insert 54 forms an abutment edge 57 that interacts with the lower sealing element 60 of the closure unit 1 and forms a lower sealing surface.

[0042] The closure unit 1 further includes a circular control base member 30 with an external thread 39 through which a detachable connection to the body base member 50 is established. Thus, when the drinking bottle closure 100 is in use, the control base member 30 is fixed to the body base member 50 and forms the fixed part of the closure unit 1.

[0043] The movable and detachable parts of the closure unit 1 include:

[0044] - the button 10;

[0045] - An intermediate housing member 11, which is connected to the button 10;

[0046] - A compression spring 13, which is supported on the inner ring 33 of the control base member 30 and on the intermediate housing member 11;

[0047] - A star member 20, which in the illustrated embodiment includes a lower part 21 and an upper part 22;

[0048] - A sealing element 60, which has a peripheral gasket 63 with a U-shaped profile cross-section;

[0049] - A pre-venting air valve 40, which is connected by a shaft 42 to a projection 14 formed at the top of the intermediate housing member 11, and which is inserted through a sealing piston 41 into a central venting opening 61 of the sealing element 60.

[0050] The upper part 22 of the star member 20 is guided in the projection 14, and its lower part 21 is supported on the sealing element 60.

[0051] The pre-venting air valve 40 has a dual function in the drinking bottle closure 100 according to the invention. On the one hand, it serves as a valve to directly release the potential overpressure inside the container at the beginning of the opening process, which will be explained later. On the other hand, it serves as a central shaft for mechanically connecting the intermediate housing member 11 together with the button 10 to the lower sealing element 60. In its function as a connecting member, the pre-venting air valve 40 is subjected to a tensile force by the compression spring 13.

[0052] Figure 3 is a top view of the control base member 30. On the outer edge, flow openings 34 are provided in an alternating order, which are used to transfer liquid from the inside of the drinking bottle to the pouring edge, and additional recesses 38 guide finger-shaped support members of the intermediate housing member. The central recess 31 is used to accommodate the star member. Four pins 35, 37 extend into the central recess 31, and they are divided into two groups:

[0053] - The fixed pin 37 in the first group of pins extends from a tab 32 surrounding the central recess 31 into the central recess 31.

[0054] - The movable pin 37 in the second group extends from a radially movable bow-shaped support arm 36 to the central recess 31; the movable pin 37 extends radially further into the center of the central recess 31 than the fixed pin 37.

[0055] Figure 4 is a perspective view of a part of the control base member 30, showing the different shapes of the two groups of pins 35, 37. The immovable pin 37 formed on the fixed part of the tab has an optimized shape to interact with the toothed profile of the star member. The rounding on the side located in front in the rotational direction facilitates scanning of the toothed profile.

[0056] The pins formed on the radially movable support arm 36 have the same shape in the region close to the support arm. A crown portion is connected here, and this crown section is arranged to interact with the stop profile between the teeth.

[0057] Figure 5 A perspective view of the two-part star-shaped member 20 is shown. A central recess 29 is provided on the star-shaped member 20, through which the pre-ventilation valve passes. A toothed profile 24 is formed on the upper part 22 of the star-shaped member 20, and a toothed profile 23 is formed on the lower part 22. According to the known principle of the so-called "ballpoint pen drive", the toothed profiles 23, 24 on the rotatable star-shaped member 20 interact with the fixed pins on the control base member, and each axial movement of the star-shaped member causes it to rotate by a certain angular step. The two-part design facilitates assembly. One of the two elements is brought to the control base member from above and one from below, so that the pins are positioned between the toothed profiles, and then the two parts are locked together to form the star-shaped member 20.

[0058] The gist of the present invention is the circumferential region between the toothed profiles 23, 24, which significantly recedes from the region having the teeth 23, 24, so that the edges of the teeth 23, 24 are wide enough to be reliably scanned by the pins of the control element. However, the circumferential region is not cylindrical, but is designed in such a way that, in the intended direction of rotation, the circumference gradually widens outwards in the form of a rising slope at least at one point, and then suddenly recedes radially inwards again.

[0059] The peripheral region forms a locking profile 25 for the pins on the control base member 30. Figure 6 The cross-sectional view of the star-shaped member 20 in clearly shows the profile in the locking profile 25: a total of four triangular profile parts are formed, and each triangular profile part forms a stop profile part 26. One of the movable pins 35 initially slides on the rising slope 26.1 and is thus pressed outwards. After passing the tip of the triangular profile, it bounces back and then is fixed to the stop edge 26.2, so that the star-shaped member 20 cannot rotate back in the opposite direction.

[0060] In Figure 7 a perspective view of the control base member 30 and the star-shaped member 20 assembly is shown, where a part is separated from the control base member 30 to show the pin 35 engaged with the locking profile 25. The pin 35 is formed on the support arm 36, which is a continuation of the tab 32, but the support arm 36 excludes the adjacent part of the inner ring 33, so that the support arm 36 is radially movable and can spring outwards.

[0061] Figure 8 Shows the same view of the control base member 30 and the star-shaped member 20 as in Figure 7 where the support arm 36 springs outwards with the pin 35.

[0062] Figure 9 and 10 each shows a detailed cross - section of a top view of the connection between the control base member 30 and the star member 20: In Figure 9 it, the support arm 36 is spring - loaded. The pin 35 is located behind the locking edge 26.2. As shown by the arrow, reverse rotation of the star member 20 relative to the control base member 30 ( Figure 9 in the counter - clockwise direction in) is not possible. On the other hand, if the star member 20 rotates in the other direction as shown in Figure 10 it, the pin 35 can slide along the rising inclined plane 26.2, causing it to move outward together with the support arm 36.

[0063] Figure 11 is a side view of the pin 37 guided between the toothed profiles 23, 24 on the star member 20. A fixed pin is chosen as an example in this illustration; the spring - mounted pins are considered to be of the same type in terms of their interaction with the toothed profiles 23, 24. For the purpose of illustration, in Figure 11 it, the pin 37 is shown twice at different axial positions relative to the central axis of the star member 20 extending from bottom to top, and also appears to move laterally. In fact, the position of the pivot 37 on the control base member 30 is fixed, while the axial position of the star member 20 changes as it moves. Similarly, the circumferential area scanned by the fixed pin 37 changes as the star member 20 rotates.

[0064] The pin 37 is positioned in the lower recess of the lower toothed profile 23 at the position shown in the lower left. This position will be assigned to the closed position of the drinking bottle closure. There, the pin 37 is not firmly against the toothed profile 23, thus avoiding accidental partial opening of the closure unit via the pin 37 and the star member 20. Instead, by allowing the pin 37 to move to a certain extent, geometric tolerances or settlement phenomena on the resilient body element can be compensated, and the sealing plane remains tight by the force of the compression spring.

[0065] At the position shown in the upper right, the pin 37 is in the open position. Here, it is in direct contact with the toothed profile 23 because the two sealing planes of the closure unit must overcome the force of the compression spring and remain open due to positive contact.

[0066] The direction of rotation of the star member 20 is indicated by the block arrow. The pin 37 is rounded in the direction of rotation to slide better along the toothed profile 23. The upper toothed profile 24 is used to first grip the pin 37 during the rotation of the star member 20 so that they do not rise too far upward, and then prepare the pin 37 to move further into the recess on the lower toothed profile 23.

[0067] In Figures 12 to 14The sectional views show the operation of the drinking bottle closure 100 at different stages:

[0068] Figure 12 The closed state is shown. The closure unit 1 is inserted into the body base member 50. The double-walled drinking bottle 101 is connected to the body base member 50 through its neck 102. The seal between them is provided by the gasket 59. The button 10 rests on the sealing lip 53 and closes the upper sealing surface. The sealing element 60 abuts against the lower contact edge 57 with its gasket 63. A direct seal of the interior of the drinking bottle 101 is achieved in this lower sealing surface, while liquid residues located inside the closure unit 1 are retained at the upper sealing surface, so that the drinking bottle 101 together with the drinking bottle closure 100 can also be transported upside down.

[0069] In addition to the known double-sealing function with two sealing levels, the drinking bottle closure 100 according to a preferred embodiment of the present invention also provides additional functions. During Figure 12 the shown closed position, the pre-ventilation valve 40 and its sealing piston 41 are pulled into the ventilation opening 61 of the lower sealing element 60 and seal it.

[0070] If the user presses the button 10 to open the drinking bottle closure 100, as Figure 13 shown, the intermediate housing member 11 first descends slightly without the star member 20 having already moved axially. Only the sealing plunger 41 located on the pre-ventilation valve 40 is pushed out of its sealing seat. If there is overpressure inside the drinking bottle 101, this can be at least partially compensated within the volume of the closure unit 1 between the upper and lower sealing elements. During this stage, the upper and lower sealing planes each remain closed.

[0071] By further pressing the button 10, the movable part of the closure unit 1 drops significantly, such that the button 10 lifts off the sealing lip 53 and the sealing element 60 lifts off the abutment edge 57. At this time, the pouring opening 52 opens. The liquid from the drinking bottle 101 can flow through the flow opening in the control base member 30.

[0072] Since the star member 20 also moves axially with further opening pressure, it rotates due to the engagement of the scanning toothed pins. This first results in holding the sealing element of the closure unit in the Figure 14 shown open position. Subsequently, further pressure creates a position of the pins between the teeth, which again allows the expansion of the compression spring 13, such that the sealing elements 10, 60 are pushed back to their sealing positions.

[0073] Figure 15 An alternative embodiment of the body base member 50' is shown in a perspective view. The shapes of the pouring edge 51, the pouring opening 52, the sealing lip 53, etc. generally correspond to Figure 2The shape of the main body base member 50 shown. Differently, a total of four guiding tabs 58' are formed on the inner wall of the pouring opening 52, offset from each other by 90°, and extend over a part of the height of the pouring opening 52, i.e., over the upper height region. The guiding tabs 58' extend radially inwards from the wall at least until or even beyond the ridge forming the thread 55.

[0074] As Figure 16 shown, in the case where the closing unit with the button 10 is inserted into the main body base member 50', the guiding tabs 58' are formed in the height region in which the button 10 of the pouring opening 52 moves. If the user presses the button 10 in the peripheral region rather than in the center, the button 10 may tilt. Here, the outer edge of the button 10 abuts against at least one guiding tab 58', thereby restricting the degree of tilt. In addition, during all movement phases, the button is centered within the pouring opening 52 by the guiding tabs 58'.
