[Selection] FIG.

Description

  The present invention relates to a container sealing cap. In particular, the present sealing cap is suitable for sealing beverage bottles, and is particularly suitable for plastic and glass bottles.

  In devices commonly used to seal beverage bottles, around the bottom of the plastic or metal cap, through at least a portion of the connection cage (web) that breaks / ruptures when the bottle is opened. It is known to provide a ring or a plurality of separating elements connected to the cap. If the bottle has already been opened, the consumer can recognize this condition. However, in such a sealing cap, if the connection cage (web) is stretched from the beginning and damaged, the cap is slightly opened, gas or liquid leaks, and foreign substances and other liquids enter the container. There is a drawback that it can penetrate. In the case of the carbonized pop soda drink or water containing carbon dioxide, when such a state is reached, for example, at least a part of carbon dioxide leaks and the quality of the drink deteriorates. Furthermore, since the sealing cap may be slightly open, there is a risk that the contents of the container will be contaminated and foreign objects may enter the container.

  In order to avoid such drawbacks, it is known from WO 02/057141 to provide a sealing housing with two sealing caps, namely an outer sealing cap and an inner sealing cap surrounded by it. . A screw is provided on the inner surface of the inner sealing cap and is configured to be screwed into the bottle neck. An inner cap that serves as a sealing element for sealing the outlet opening of a container such as a beverage bottle has a closure on the upper surface for closing the pressure compensating opening in the inner cap. In addition, a drawing element and a catch element are provided on this upper surface. The outer cap surrounding the inner cap rotates by a predetermined angular range with respect to the inner cap. On the inner surface of the outer cap facing the upper surface of the inner cap, an arm composed of a cutting edge is provided. By rotating the outer cap, the cutting edge of the arm cuts the closed portion of the inner cap, i.e. the pressure compensation opening. When the outer cap is further rotated, the arm of the outer cap abuts against the holding element of the inner cap, and the inner cap is also rotated together. As a result, the bottle can be opened. In addition, catch elements are provided on the opposing surfaces of the two caps to prevent the outer caps from being rotated back against the inner caps. As soon as the sealing cap is opened, the blocking portion of the inner cap is removed. Since the outer cap is transparent, this is recognized by the consumer.

  However, for this purpose it is absolutely necessary that the outer cap be transparent. Further, this sealing cap has a problem that the consumer may easily overlook that the blocking portion has already been removed.

  An object of the present invention is to make it possible to reliably confirm that a cap has not been opened by a third party in a sealing cap having an unauthorized opening prevention function.

  This object according to the invention is achieved by the features of claim 1 of the claims.

  The sealing cap according to the invention comprises a sealing element for sealing the outlet opening of a container, in particular a bottle, particularly preferably with or without carbon dioxide, whether or not it contains a beverage plastic or glass bottle. The sealing element preferably comprises a cap-shaped configuration. Furthermore, the sealing cap according to the invention comprises a safety element which is incorporated in the sealing element so as to be displaced from the closed position to the open position. Prior to opening, the safety element is in the closed position and rotates to the opening position by being displaced, i.e. by being twisted once (only once) with respect to the sealing element. According to the invention, once the safety element is moved to the closed position, the safety element is no longer displaced or untwisted to the opening position. The safety element may be an annular or cap-shaped element. In particular, the safety element may be disposed within the sealing element or without the sealing element, and may in particular partially enclose the sealing element, and more preferably completely enclose the sealing element. good. In a first embodiment, in order to prevent the safety element from being twisted or returned from the open position to the closed position, the release means can be connected between the two elements so that it can be connected to the sealing element and the safety element. Arranged. The release means serves to allow or release the twisting of the sealing element to fully open the element. For example, for this purpose, a latch that engages a well in the bottle may be pulled back by the release means. Preferably, however, the release means consists of a catch element, with which the safety element is connected to the sealing element and rotates with the sealing element. As described below, a retention mechanism may be provided between the sealing or safety element and the bottle neck or other container opening wall.

  Indicating means (means for showing evidence of tampering) are coupled to the sealing element and / or safety element to indicate to the consumer that the beverage bottle or other container has already been opened. The display means displays whether the sealing cap has been in the opening position so far. For this purpose, an actuating means is connected to the safety element and / or the sealing element, the actuating means serving to actuate the display element. In this case, the actuating means is displaced with respect to the display means and actuates the display means. The actuating means may be provided on either the sealing element or the safety element, preferably the indicating means is provided on the other element.

  The indication means are provided outside the sealing element or safety element, i.e. outside the sealing cap so that the consumer can recognize as easily as possible whether the sealing cap has been moved to the opening position. To do. The indicating means may be provided on the sealing element or the safety element, and according to the invention the indicating means are provided on the outside, i.e. on the element side not covered by each other element. In this case, it must be taken into account, for example, that the safety elements may be configured as rings, so that these elements do not have to be completely covered with one another. According to the present invention, the position of the display means changes at the time of opening, that is, when the safety element is moved from the closed position to the opened position. For example, such a state occurs when the display means is at least partially pushed out. Such a change in position occurs outside the sealing element or safety element and is therefore easily perceived by the consumer. In particular, since the change in the position of the display means can also be perceived, it is recognized by blind consumers. In this case, it is particularly preferable to provide the display means on the upper surface, not the outer surface of the sealing cap, so that the display means can be seen and felt. The display means may be configured with a color different from the color of the sealing cap, in particular, a signal color.

  The purpose of the present invention is also to prevent foreign objects and liquids from entering the container between the bottling factory and the actual purchase place without the knowledge of the consumer. Objective.

  After the cap has ruptured even a little, when the container is closed by an undercap (which contacts the liquid in the container), it is according to the present invention to show all the sealing properties seen before the cap is opened. The mechanism works.

  In a particularly preferred embodiment, the actuating means of the tamper evident mechanism is configured as an inclined part. In the present invention, when the safety element and the sealing element are displaced or twisted with respect to each other, the display means is pushed out. Preferably, the state is generated by displacing the display means perpendicularly to the displacement direction along the inclined portion to displace the display means, or twisting and pushing the display means to the outside. The change in the position of the display means generated thereby is directed to the outside. That is, the display means protrudes outside the sealing cap. Preferably, the display means is connected to the sealing element or the safety element via a thin plate. When the display means changes its position, preferably the cutting of the sheet should be avoided. Preferably, the state can be reliably generated by providing a thin plate on the side facing the front end of the inclined portion at the opening position.

  It is also possible for the connecting element and the indicating means to be arranged between each of the sealing element and the safety element so that the indicating means protrudes outward in the lateral direction of the upright container in the open position. Preferably, however, the connecting element and the indicating means are arranged between two horizontal end faces when the container is in an upright position. In a preferred embodiment, the sealing element and the safety element are configured as a cap, preferably the safety element surrounds the sealing element.

  Preferably, the sealing cap according to the present invention further comprises pressure compensating means which serve to reduce the pressure in the container when the container is opened. Preferably, the pressure compensation means is activated before the safety element reaches the opening position. Preferably, the pressure compensation means includes a cutting element. By displacing the safety element, the cutting element can take and cut off the closure that closes the pressure-compensating opening of the sealing element. In the case of beverages other than carbon dioxide or effervescent liquid, gas is not generated so much, so this concept is not necessary, and a cutting mechanism and a corresponding blocking portion may be selectively provided.

  Preferably, pressure compensation means are arranged in the storage chamber so that the isolated blockage does not interfere with or enter between the sealing element and the safety element so as not to impede the operation of the sealing cap.

  Preferably, a sealing ring is disposed in the groove of the sealing element to prevent a small amount of gas from escaping from the container. For this purpose, preferably with the sealing cap screwed in, a sealing ring is arranged between the inner wall of the outlet opening of the container and the wall of the groove and contacts both surfaces. The wall of the groove is disposed in the outlet opening.

  When the closure is cut so that excess gas exits the bottle, a mechanism is optionally provided to generate a specific sound, such as a pop (such as a champagne cork) or a whistle (for a children's party).

  Furthermore, an RFD (Radio Frequency Device), which is a dormant chip (transponder) that can be operated by an external radio source, may be included in the cap. This technique may be used for many applications such as code bar substitution, inventory management, prize award (raffle), research, and the like.

  According to a particularly preferred embodiment, the safety element or sealing element of the sealing cap according to the invention comprises at least one holding element. Preferably, a plurality of the above-mentioned presser elements, especially three presser elements, are provided at positions distributed around the periphery. Initially, when the container or bottle is opened, the at least one holding element ensures that the safety element is displaced relative to the sealing element. The indicator means is actuated by the actuating means, in particular in the case of a torsion of a safety element whose displacement is a twisting movement of the two elements relative to each other. In this regard, preferably the at least one presser element has at least one presser element such that, for example, when the sealing element is twisted to open the container, the safety element is initially held in place. Composed. For example, the safety element is held by rotating the sealing element by 1/4 or 1/2 turn. In this process, the display means is actuated via the actuating means. After this, the safety element can be rotated together with the sealing element.

  Preferably, at least one hold-down element is arranged to cooperate with at least one holding element arranged on the container, in particular the bottle neck. Preferably, at least one holding element is arranged on the outer part of the container or bottle neck. Preferably, several holding elements correspond to several holding elements.

  According to a particularly preferred variant of this embodiment, when the presser element is provided on the safety element, at least one presser element extends through an opening formed in the sealing element. If the hold-down element is provided on the sealing element, the opening is likewise provided on the safety element. Preferably, the opening is formed as a section of the annular ring. Preferably, a plurality of said openings are provided, preferably one corresponding opening is provided for each presser element. According to a particularly preferred embodiment, the safety element, which is preferably disc-shaped, acts as a holding element, preferably a protrusion extending inwardly, i.e. towards the container, through an opening in the connecting element. A part. In the closed state, at least one pressing element is arranged between the wall area of the container opening such as the bottle neck and the sealing element. Preferably, the safety element is disk-shaped and is arranged in the depth of the sealing element. Accordingly, the cap-shaped sealing element preferably has an upper end side on which a circular depth corresponding to the disk-shaped safety element is formed. An opening extending through a plurality of openings and preferably comprising a pressing element is provided in this depth, in particular along the outer edge of the depth.

  After the first rotation, the connecting element is configured to connect the safety element and the sealing element. During this first rotation, the sealing element is rotated with respect to the safety element held in place by the holding element. During this first rotation, the position of the display means changes to indicate that the bottle or container has been partially opened. With this initial rotation, the bottle or container is not yet fully opened. A connecting element is provided to hold the safety element in place with respect to the sealing element so that the position of the indicating means does not change any further. Preferably, the connecting element consists of a snap-in lock or similar device.

Hereinafter, the present invention will be described in detail with respect to preferred embodiments with reference to the accompanying drawings.
In the preferred embodiment shown (FIGS. 1-15), the sealing element 10 (FIGS. 1-5) is configured as a cap with a threaded portion 12 therein. Thus, the sealing element 10 comprises a substantially cylindrical outer peripheral surface 14 with a plurality of protrusions and shoulders. A retaining ring 16 (FIG. 4) is provided on the outer peripheral surface 14. The retaining ring 16 serves to hold the safety element 18 (FIGS. 6-9) in the illustrated embodiment, and when the safety element 18 is configured as a cap and assembled into a sealing cap (FIG. 14), Encloses the sealing element 10 completely. Here, the retaining ring 16 engages in a circumferential groove 20 (FIG. 9) provided in the inner surface 22 of the safety element 18 (FIG. 14).

  Furthermore, the outer peripheral surface 14 of the sealing element 10 is provided with a release means comprising two stops 24, 26 and a catch element 28. The release means serves to securely connect the sealing element 10 to the safety element 18 (see below). Furthermore, the release means 24, 26, 28 are also provided on the opposite side of the outer peripheral surface 14 of the sealing element 10 (FIG. 5).

  The end face 30 of the sealing element 10 is provided with actuating means 32 configured in the illustrated embodiment as two ramps. The actuating means 32 serves to actuate display means 34 provided in the safety element 18 (FIGS. 6-9). Furthermore, a protruding portion may be arranged between the two caps, that is, between the sealing element 10 and the safety element 18.

  Furthermore, an annular protrusion 36 is provided on the end face 30 of the sealing element 10 so that a storage chamber 38 is formed in the annular protrusion 36. In the storage chamber 38 provided on the end face 30, a cylindrical closing portion 40 constituting pressure compensation means is provided together with a cutting element 44 (FIG. 8) provided on the inner surface 42 of the safety element 18 (FIG. 8). 9).

  Furthermore, the sealing element 10 is provided with an annular groove 48 (FIG. 4) inside the cap. A sealing ring 50 is disposed in the groove 48 (FIGS. 14 and 15). When the sealing element 10 is screwed (FIG. 14), the upper end 52 of the container bottle neck 54 is pushed into the groove 48. This compresses the seal ring 50 so that the seal ring 50 is substantially perpendicular so that a portion of the seal ring 50 is disposed between the inner wall 56 of the container neck 54 and the wall 58 of the groove 48. Cross section. This ensures that the container outlet opening 60 is sealed by using the sealing element 10 according to the present invention. The sealing ring 50 is illustrated in both FIGS.

  In order to attach the sealing cap, for example, the sealing element 10 configured as a cap is first screwed into the bottle neck 54 of the container, i.e. the threaded portion 62 provided on the bottle neck. Let In this case, the upper end 52 of the bottle neck 54 is introduced into the groove 48 inside the sealing element 10. The container is now securely sealed. Furthermore, the lower edge 64 of the sealing element 10 contacts the circumferential support ring 66 of the container and is more securely sealed.

  In the next step, the safety element 18 (FIGS. 6-9), configured as a cap in the illustrated embodiment, is pressed from above onto the sealing element 10 in place. A position is selected such that the cutting edge 68 (FIG. 8) of the cutting element 44 is disposed in front of the cylindrical closure 40 in the counterclockwise direction of rotation. Here, the two opposing catch elements 70 provided on the inner wall 22 of the safety element 18 (FIG. 8) are connected to the inclined catch elements 28 arranged on the surface of the sealing element 10 in opposition thereto. Arranged forward in the counterclockwise rotation direction (FIGS. 2 and 3). Furthermore, the cylindrical display means 34 provided on the end surface 72 (FIG. 6) of the safety element 18 is also disposed in front of the two inclined portions acting as the actuating means 32 in the counterclockwise rotation direction.

  As long as each element described above is in front of the corresponding element in the counterclockwise direction of rotation, the sealing cap is in a closed position where the container is not opened. To open the container for the first time, ie to open the sealing cap, the safety element 18 is rotated counterclockwise. Due to the friction between the sealing element 10 and the bottle neck 54, the sealing element 10 initially does not rotate with the safety element 18. When the safety element 18 is rotated in the counterclockwise direction, the display means 34 is moved toward the actuating means 32 configured as two inclined portions and is further pushed outward by the actuating means 32 to display the display. The means 34 changes its position and protrudes to the exterior 74 (FIG. 7). Since the position of the display means 34 changes in this way, it can be clearly recognized that the container has already been opened, and can also be perceived by touch. In order to avoid disappearance of the display of the display means 34 by a strong touch, the display means 34 is fixed to the safety element 18 by the thin plate 88 (FIG. 6).

  During this rotation, the catch element 70 (FIG. 6) slides on an inclined catch element 28 which is arranged opposite to the outer peripheral surface 14 of the sealing element 10. At this time, the safety element 18 is slightly elastically deformed at this portion. After the catch element 70 passes over the inclined catch element 28, the catch element 70 enters the space 76 (FIGS. 2 and 3) between the catch element 28 and the stop 26. When the catch element 70 enters the space 76, the safety element 18 cannot be rotated back in the clockwise direction unless it is together with the sealing element 10. Similarly, the safety element 18 cannot be continuously rotated in the counterclockwise direction unless together with the sealing element 10. Thus, since the sealing element 10 is rotated with the safety element 18, the container is completely opened by continuously rotating the safety element 18 in the counterclockwise direction.

  The pressure compensation means 40, 44 are simultaneously activated by the two steps described above, ie, the actuation of the display means 34 by the actuating means 32 and the fitting of the catch element 70 into the space 76. For this purpose, a cylindrical projection 78 (FIG. 2) is provided in the center of the storage chamber 38 of the sealing element 10 and engages the cylindrical recess 80 (FIGS. 6-9) of the safety element 18. Furthermore, a protrusion 82 (FIG. 9) is provided on the interior 72 of the safety element 18 that engages the guide groove 84 (FIG. 2) of the sealing element 10. When the safety element 18 is first rotated counterclockwise, the cutting edge 68 of the cutting element 44 cuts the closure 40 as soon as the indicator means 34 is pushed outward and the catch element 70 enters the space 76. To do. By cutting off the closing portion 40, the pressure compensation opening 86 (FIG. 1) provided under the closing portion 40 is opened. Thereby, since a small amount of gas escapes through the pressure compensation opening 86, there is an advantage that the first opening process is easily performed. Due to the storage chamber 38 defined by the annular projection 36 and the end face 30 and the interior of the end face 72 of the safety element 18, the cut closure 40 is securely held in the storage chamber 38.

  Here, the sealing cap is in an open position where the safety element 18 and the sealing element 10 are connected to rotate together. In this case, the sealing cap can be repeatedly screwed onto the container and removed again.

  Furthermore, in a preferred embodiment (FIG. 16), the annular safety element 90 is disposed inside a sealing element 92 configured as a cap. In this embodiment, the display means is provided on the outer surface of the sealing element 92 and is actuated by actuating means attached to the outer surface of the safety element 90. The necessary release means, usually made up of catch elements, are also arranged between the outer surface of the sealing element 92 and the safety element 90. If necessary, appropriately designed pressure compensation means may also be provided in this region.

  In another embodiment (FIG. 17), the safety element 94 is configured as an annular ring, and the safety element 94 surrounds a sealing element 96 configured as a bottle cap. In this case, for example, the indicating means are arranged on the inner surface of the safety element 94 and the corresponding actuating means are arranged on the surface of the sealing element 96. Furthermore, the release means, usually consisting of a catch element, is arranged between the safety element 94 and the sealing element. Within this region, pressure compensation means may be provided as necessary.

  In the embodiment illustrated in the two schematic views of FIGS. 16 and 17, one of the sealing element 92 and the safety element 94 is rotated in the initial opening process, and each other element is now together. Does not rotate. The display means is activated by the actuating means that can be configured in the manner described above and, as explained above, each other element only after the two elements are connected by the release means comprising the catch means. Are rotated together, and the container is completely opened.

  Also with reference to FIGS. 18-24, another particularly preferred embodiment of the sealing cap is described below.

  According to this embodiment, the sealing cap consists of a sealing element 100 formed as a cap and a disc-shaped safety element 104 arranged in its circular depth 102 (FIG. 19). An internal side region 106 of the cap-shaped sealing element 100 facing the container or bottle neck 108 is formed in the screw 110. The screw 110 is configured to engage with a screw 111 formed on the outer side surface of the bottle neck 108.

  The sealing element 100 is composed of a disk-shaped member 114 that closes or covers the bottle or container opening 116 and an annular member 112 that is continuous therewith and surrounds the bottle neck 108. Preferably, the disk-shaped member 114 is provided with a circular protrusion 118 extending into the bottle opening 116. The protrusion 118 protrudes toward the inner side 120 of the bottle neck 108 in order to seal the bottle. Further, preferably, a reinforcing rib 122 is formed on the bottom of the disk-shaped member 114.

  In an annular region 124 that is substantially disposed between the outer surface of the bottle neck 108 and the inner surface 106 of the annular member 112 of the sealing element 100, a plurality of openings 126 are provided along the periphery of the region 124. In the illustrated embodiment, three openings are provided, and these openings 126 are formed as partitions of the annular region 124. A holding element 128 (FIG. 21) provided on the safety element 104 is inserted into each opening 126, and the holding element 128 is disposed between the bottle neck 108 and the annular member 112. In the illustrated embodiment, three presser elements 128 are continuous to the safety element 104 (FIG. 21). For clarity, the safety element 104 is not shown in cross section in FIG.

  On the upper surface region 130 (FIG. 19) of the disk-shaped member 114 in which the depth portion 102 is formed, as the operating means having the same function as the operating means 32 having the inclined portion described in relation to the above-described embodiment, Actuating means 132 having a portion is provided. Therefore, the safety element 104 is provided with a display stage 134 having the same function as the function of the display means 34 described above. Here, similarly, the display means 134 is connected to the safety element 104 via the thin plate 136.

  Before the sealing cap is opened, first, the sealing cap is placed in the position shown in FIG. In this position, each of the presser elements 128 is disposed in front of the holding element 138 in the counterclockwise rotation direction. Each holding element 138 includes a side surface 140 that faces the presser element 128. Initially upon opening of the sealing cap, the sealing element 100 is first rotated counterclockwise, that is, in the direction marked by the arrow 142. At the beginning of this rotation, the presser element 128 strikes the side 140 of the holding element 138 so that the safety element 104 is fixed in the initial position. As a result, relative movement between the sealing element 100 and the safety element 104 occurs. By this relative movement, the operating means 132 (FIG. 19) having the inclined portion is rotated to a position below the display means 134. Since the display means 134 is provided with the downward projecting portion 135 or the corresponding inclined portion, the display means 134 is pushed upward by the relative movement, and the display means 134 at the reached opening position can be visually recognized. It is also perceived by tactile sense.

  Actuation of the indicator means 134 via the actuating means 132 is effected by rotating the sealing element 100 within a range of 90 ° to 180 °. Due to the thread pitch, the sealing element 100 is moved upward together with the safety element 104, i.e. out of the opening 116 of the bottle in the direction of the arrow 144 (FIG. 21).

  As a result, after the first rotation, the presser element 128 is lifted so that it can be disposed on the holding element 138 and rotated through it. Here, both the sealing element 100 and the safety element 104 are rotated. Therefore, in this case, the sealing cap can be completely opened.

  In order for both the sealing element 100 and the safety element 104 to be reliably rotated, the connecting elements 154, 156 are respectively connected to the safety element 104 and the sealing element 100 or a part of the safety element 104 and the sealing element 100. It becomes. In the illustrated embodiment, a connecting element 154 (FIG. 23) having three ramps is connected to the inner surface 158 of the safety element 104. The inner surface 158 faces the upper surface 130 or the outer end surface 130 of the disk-shaped member 114 of the sealing element 100. Preferably, the connecting element 154 is connected to a circular ring 160 protruding in the direction of the sealing element 100. A corresponding portion of the connecting element 154, ie a connecting element 156 (FIG. 24) consisting of an opening, is also arranged on a circular line on the upper surface 130 of the sealing element 100. On the other hand, the connecting element 156 is disposed with respect to the opening 126 and is preferably not formed as a through opening. Thus, the safety element 104 is fixed and the safety element 104 is connected to the sealing element 100 so that it does not rotate so that the connecting element 154 does not engage the connecting element 156 as a result of the first rotation when the sealing element 100 is rotated. The Even if the bottle or container is opened and closed several times, the safety element 104 and the sealing element 100 are not separated from each other due to the connection of the connecting elements 154, 156. After the connection elements 154, 156 are connected, the safety element 104 cannot be rotated relative to the sealing element 100.

  In order to be able to rotate, the container must first be closed and the sealing means 128 is not damaged and is simply screwed on the sealing cap again, protecting it as soon as the presser element 128 reaches its proper position. When worn, the holding element 138 has an inclined shape and is formed by a rising slope 146 that faces clockwise. Therefore, while the container is first closed, the presser element 128 can slide on the rising slope 140, so that the front position of the fixed side surface 140 is restored in the counterclockwise rotation direction as shown in FIG.

  Preferably, the safety element 104 is held for rotation within the depth 102 (FIG. 19) of the sealing element 100 and is secured from falling. For this purpose, a locking device is provided, in the illustrated embodiment, in which the circular edge 148 (FIG. 19) projects into the depth 102 and is provided on the safety element 104. A pawl 150 is provided so as to be engaged with the rear portion of 152. Both the sealing element 100 and the safety element 104 are preferably made from an elastic material, in particular plastic, and the safety element 104 in FIG. 19 is pushed from the top to the depth 102 and is rotated in the depth 102 by the locking device. To be held.

  Furthermore, in the embodiment described with reference to FIGS. 18-24, the pressure compensation means 40, 44 can be provided in a manner similar to the embodiment in FIGS. 1-17. Preferably, as already described, the pressure compensation means 40, 44 is a closure member arranged to close the pressure compensation opening 86 within the sealing element 100, as seen, for example, in FIGS. It consists of a cutting element 44 for removing 40.

  In all of the above embodiments, the screw portion extends in the transverse direction with respect to the longitudinal direction of the screw portion in addition to or without the pressure compensation means, and the screw portion is interrupted. Since the slit to be provided is provided, pressure compensation becomes possible. Thereby, gas can escape at the time of opening.
