Description

Closure for a fluid-filled container

description

The invention relates to a closure with a sealing element for a container filled with fluid according to the preamble of claim 1. From the prior art closure systems are known, which are used by means of sealing film or tamper evident for anti-counterfeiting of, for example, drugs or drinks to the originality state after the display manufacturer's filling process. Films can also serve as protective barriers to extend the shelf life of sensitive contents by providing greater leak tightness than do simple caps or caps with prior art dosing inserts.

Closure systems are also known from the prior art, which include dosing elements applied in the container opening. Such closure systems have not been simultaneously protected by barrier films, especially not when the container openings are relatively small.

In known closure systems of the prior art sealing films are opened by the initial opening screwing or must be removed later. Tamper evident strips tear off visibly when first screwed on. Sieve films arranged under screw caps do not represent a reliable tamper-evidence because they are not visible, but the closure itself must be secured against opening.

CONFIRMATION COPY The document DE 43 23 666 A1 describes a self-pierceable closure device for vials. A seal seal is provided on the outside of the closure device which must be torn off to gain access to the contents of the vial. The warranty seal can thus fulfill the function of a tamper evidence. However, installing the warranty seal on the outside of the machine may damage or manipulate it in production or transportation.

Object of the present invention is to provide a particularly tamper-proof as well as simple design and inexpensive to produce, easy to handle closure.

This object is solved by the subject matter of claim 1. Further advantageous embodiments are the subject of the dependent claims.

According to the invention, a closure with a sealing element for a container filled with fluid having at least one securing mechanism which is designed to be visibly irreversibly changed when the closure is first opened is provided. The irreversible change can be demonstrated, for example, by the fact that an element of the closure is torn off by opening, broken off, permanently deformed and / or changed in color. Such a securing mechanism undoubtedly makes it clear to the consumer whether the closure is still originally sealed. As a result, the consumer can recognize whether the contents of the container is still in its original state or has been impaired by, for example, its durability, or possibly manipulated and / or contaminated by previously opening the closure.

The securing mechanism may comprise at least one visible securing element, which is visibly irreversibly changed upon application of the closure to the container with a force having at least one force component along an axis normal to an opening plane of an opening of the container closed by the closure. The said force is greater than the force that a user would normally apply to open the closure and, in particular, significantly greater than forces normally encountered during shipment of the closure and container. By its direction, the force causes the closure to move toward or away from the mouth of the container path. A visible irreversible change thus occurs in particular when an attempt is made to remove the closure from the container or to press against the container, for example, to gain access to the opening and thus to the contents of the container. The solution according to the invention also indicates an unintended intervention, for example due to improper handling or improper transport, in the closure.

The securing element can be arranged on the side of the closure facing the container and / or designed for spacing the closure from the container. As a result, it can be designed in a structurally simple way so that it is irreversibly changed in the mentioned application of force and / or obstructs opening of the container reliably.

The securing element can be connected to the closure via at least one, for example, zuglabile, in particular radially zuglabile, predetermined tear. By the predetermined breaking point, the securing element can solve under a, in particular selectively radial, force application in a predictable manner and easily visible from the closure. Alternatively, the securing element may comprise a predetermined bending point. The buckling of the security element defined by the predetermined bending point is preferably visible and irreversible. According to a particular embodiment of a securing element with predetermined bending point, the securing element can be pushed completely or only partially under the closure or in particular the first and / or second element by moving the first and second elements into the second position. In addition to the display effect, this pushing can also have a clamping action to additionally secure the closure in the second (use) position.

The securing element can enclose the opening which is closed by the closure, preferably in a substantially annular manner. As a result, the opening and thus the contents of the container is additionally protected against manipulation.

The securing element can be torn off from the closure, wherein the securing element may comprise, for example, a grip element, in particular a lug. By the securing element is torn off, for example, by predetermined breaking points between the securing element and the closure and / or within the Fuse element, it can be removed by the consumer to open the lock unhindered. With the help of a handle element, in particular a tab tearing is particularly easy. By the tab by a tear-off element connects the fuse element circumferentially, even accidental or premature tearing is prevented, for example, during the handling or Verschließprozesses, especially since the circumferentially mounted tear-off is advantageously designed so that it offers little access points for mechanical intervention.

The securing element and / or the first and / or second element may have latching means such as at least one latching lug, wherein the container may, for example, have at least one latching pin complementary to the latching latch. Alternatively, the at least one latching pin can also be used e.g. be arranged on the securing element and / or at least one complementary locking lug on the container. The latching lug and the latching pin can cooperate with a movement of the securing element along the axis of the container away form-fitting manner and on the container to non-positively. The terms "locking lugs" and "locking pin" are not restrictive to understand the shape of these locking elements, but are merely intended to illustrate their functional interaction. Locking means between the first and second elements secure according to the invention preferably in two latching stages two positions before engagement, namely in particular the production side set first position (eg "delivery position") of the first and second element and a second position generated by the user of the container (eg "use position" ). On the other hand, the securing element can be designed according to the invention with only one latching step in a user-induced position, with the first element, second element and / or the container as latching partner. Advantageously, the securing element does not interact or at least only weakly frictionally with the first element, so that the first element is at least largely decoupled from the force effects of the securing element.

By locking lugs and / or locking pin securing element can be reliably held in position on the container. By a non-positive connection of locking lugs and locking pin in a movement of the fuse element on the container to the closure with the fuse element can be mounted by overcoming the resistance caused by the adhesion in the filling process on the container. The positive connection in the opposite direction prevents the securing element, and in particular the closure with the securing element can be removed from the container. Advantageously, the resistance caused by the positive connection can be chosen to be greater, for example by a suitable choice of material and / or shape, than the force required for the irreversible change of the securing element. This ensures that the closure can not be removed from the container without visibly irreversibly altering the security element.

The securing element may consist of at least one elastically deformable material, preferably of a plastic. By an elastic material ensures that the fuse element is not irreversibly changed, for example, during filling or during transport, especially only in an opening attempt of the container.

The closure may comprise a second element and a first element for receiving the second element. Here, the first element and the second element are mutually displaceable from a first position to a second position, wherein in the first position, the sealing element is intact and wherein in the second position, the sealing element is pierced by the second element. The first element and second element are preferably connected together in all positions. For example, the second element may be an insert for the first element. The sealing element can be attached by means of a sealing ring in the first element and in particular be tensioned by the sealing ring. A sealing ring is also advantageous in order to obtain a reliable seal and to be able to wrestle the sealing element more easily in the first element. The sealing ring is adapted in size to the circumference of the first element, so that a reliable seal is ensured. The fluid may be, for example, a drinkable liquid, such as water, or a drinkable or inhalable, especially gaseous, or evaporating or sublimating, drug at ambient conditions.

For example, on the second element at least one control element is mounted as part of the securing mechanism, by which it can be seen whether the second element is still in the starting position. This should be obvious and easy to see whether an opening process has already been carried out to indicate the originality state for consumers. Furthermore, the at least one control element is irreversibly changed by displacement of the second element against the first element. The irreversible change of the at least one control element ensures that, if the second element is brought back into the starting position after the first opening, it can be seen that the container has already been opened. As control elements in this case, for example, so-called flaps are particularly suitable which buckle visibly and irreversibly when the second element is pressed in. In particular, the previous opening of the container can be read off from deformations or material discolorations, for example due to material fatigue on the control elements. It is also conceivable to connect the first element and the second element in an unopened initial state of the container with each other, wherein the compound can be separated by moving from the first position to the second position with little effort for a user of the container. Such a connection may, for example, be an at least partial welding of the first element to the second element. But there are also other configurations such as a mounted between the first and second element sealing strip conceivable, which breaks off when pressed and thus indicates a first opening.

The second element can substantially completely encase the first element at least on the side facing away from the container. As a result, the first element hidden and thus additionally protected against manipulation. This is particularly useful when the first element serves to fix a sealing element on the container. By hiding the first element, manipulations on the sealing element which is essential for protecting the contents of the container are thus prevented as well. In an advantageous embodiment, at least one cutting surface for at least partially or partially severing the sealing element is arranged on the second element. Such a cutting surface is advantageous to ensure reliable severing and to provide a sufficient opening through which the fluid can escape. It is conceivable to separate a section from the sealing element or to produce an opening in the sealing element which is left continuous by a preferably non-straight cut. In addition, it is advantageous that the cutting surface is a part of the second element and is located on the part of the second element, which is located in the direction of displacement closest to the sealing element. However, it would also be possible, the cutting surface via an essay or the like on the second Element to install. Furthermore, it is also possible to provide a plurality of cutting surfaces on the second element in order to cut through the sealing element at several points at the same time. The cutting surfaces are designed so that the opening formed by them can carry a fluid flow and ensures this, at least equal to that of a spout of the closure.

In a particular embodiment, the closure comprises a holding element for holding a movable section produced by cutting through the sealing element. By holding such a movable portion of the movable portion is secured in a defined holding position, so that a constant flow of fluid is ensured by the pierced sealing element. Thus, for example, prevents a flap-shaped movable portion of the sealing element is movable or fluttering in the fluid flow. The holding element may be configured, for example, spit-shaped for skewering a portion of the sealing element and is preferably movable in the penetration direction against the sealing element and more preferably provided with barbs for holding the portion of the sealing element in the penetration direction.

The closure may have an internal thread complementary to an external thread of the container. Alternatively, the closure may also have an external thread complementary to an internal thread of the container. As a result, the closure can be securely fastened to the container by screwing on. In this case, the closure may for example have a ratchet, which is designed to allow screwing the closure to the container and to prevent unscrewing of the closure of the container. Although the closure can be easily screwed on in the filling process by means of the catch, it can no longer be loosened afterwards, so that no unnoticed access to the contents of the container is possible. In particular, a possible fixation of the sealing element on the container by the closure can not be affected.

The lock may comprise a number of, for example three, driver ribs and / or a, in particular equal or integer divisible or multiple, number of, for example three, snap ribs. In this case, in particular the driving ribs can be arranged on a first part of the closure accessible from an outside of the closure and / or the snap ribs on a second part of the closure connected to the internal thread. The first and second parts of the closure may in particular be the first and second elements of the closure. Alternatively, nen driver ribs and snap ribs in their arrangement also be reversed. The driving ribs and snap ribs cooperate positively when screwing the closure, so that a rotational movement of the first part of the closure is transmitted to the internal thread, so that the closure can be screwed tight. In a Abschraubversuch the driver ribs and snap ribs cooperate only non-positively, the locking is preferably designed so that the maximum through the power fit transferable torque is lower than that for unscrewing the closure of the container minimum torque required. As a result, only the first part of the closure rotates during a screwing test, while the second part of the closure, which carries the thread, remains firmly attached to the container and, in particular, maintains the sealing effect of the sealing element.

The sealing element may be in the form of a film, preferably as a multilayer sealing film, in order to ensure a good sealing of the container interior against the environment of the container.

It is possible that the sealing element is connected cohesively neither with the closure nor with the container. The sealing element can in particular only be inserted into the closure and / or placed on the container and clamped by the attachment of the closure on the container between the closure and the container. This eliminates the need for an additional attachment step for the sealing element, for example, by welding in production and / or during filling. Advantageously, the sealing element can be clamped in the closure movable, but captive. Furthermore, it is advantageous that the sealing element is designed as a circumferential sealing element, which is made of an elastic material. It is particularly preferred that the sealing element consists of a flat closed-cell foam. This is especially suitable for PE foam, in particular because of its elasticity and its low production costs. The use of a foam offers the advantage, with regard to the sealing of the various elements, that it has a uniform contact pressure on the various elements. This also makes it possible to ensure a reliable sealing effect even with larger manufacturing tolerances in the first and the second element. In particular, the areal ausgestaltet closed-cell

Foam covered on at least one side with a film element. An additional attachment The advantage of providing a film is that the foam, in particular, for example, also for alcoholic solutions, becomes impermeable in order to ensure a reliable seal. The material used for the film is preferably aluminum. In particular, the sealing element can be provided with weak points impermeable to the fluid, which act as predetermined breaking points for a defined opening of the sealing element. The defined opening occurs, for example, in that the sealing element is torn by sliding the second element into the second position only on one side and / or is pressed to one side such that the sealing element does not substantially reduce the cross-sectional area of the opening of the container closed by the closure. As a result, in particular the combination with a metering element, which is dependent on the most unhindered flow of fluid out of the container, is made easier. >

Furthermore, advantageously in the closure, in particular in the second element, at least one, preferably exactly one, reflux channel is provided, via which air can enter the container. For this purpose, the closure, in particular the second element, be equipped with at least one ventilation hole. In a further advantageous embodiment, a channel for fluid in the closure, in particular in the second element, in particular eccentrically arranged. An eccentric arrangement and also the largest possible cross section of the fluid channel are each particularly advantageous in order to optimize the maximum flow through the return channel for a given design of the closure. Thus, a possible capillary action can be greatly reduced or completely prevented. It would also be conceivable to have a central arrangement of the fluid channel, which would result in an annular return channel. However, this is not advantageous because in a circular return channel with a small space a stronger capillary action occurs. Furthermore, a plurality of return channels are possible by a central arrangement of the fluid channel. Several return channels offer the possibility of ensuring greater structural stability through more walls between the return channels. A circumferential return passage is advantageous to a. Remaining medium in the closure element better to be able to return to the bottle. Furthermore, it is possible for the first and the second element to be sealed against one another via sealing surfaces, at least in the second position. Particularly advantageous is such a seal in the second position, since in this the sealing element is severed and the previously given by the sealing element seal is no longer completely present. For this purpose, the size of the two elements is adapted to one another in such a way that outer surfaces of the second element at least partially cooperate sealingly with complementary inner surfaces of the first element in a certain area, but at the same time displacement of the two elements relative to one another is possible. In this case, at least the first element is made of an at least partially elastic material, such as polyethylene (PE), in order to facilitate a displacement. When polyethylene is used, it can be HD (high density PE-HD) or LD (low density PE-LD) type. PP and PE are preferred as these materials have available types that are certified and approved for food or medicine. Alternatively, it is possible that the second element sealingly cooperates with the sealing element and / or the sealing ring in the second position. Such interaction of these elements is advantageous since a more reliable sealing after the first opening can be ensured.

Particularly preferably, the first element and / or second element is equipped with at least one latching lug and / or with at least one locking pin complementary to the latching lug. An equipment with locking lugs and complementary locking pin to hold the second element reliably in both the first and in the second position.

In a further preferred embodiment, the at least one latching nose acts positively only against a displacement direction positively and / or along the displacement direction frictionally. A positive connection against the direction of displacement is advantageous because such an unwanted withdrawal of the second element from the first element is reliably prevented. Furthermore, it is also prevented that the second element slides independently during transport from the first element. A non-positive connection along the direction of displacement is advantageous because a certain force must be expended to carry out the initial opening process, which prevents accidental and independent impressions or slippage of the second element during transport. Furthermore, the second element is also advantageous after being displaced on the first element by a number of latching lugs and complementary latching pins in the second position. Position - eg the position of use - secured against pushing back to maintain the tightness between the first and second element reliable. The sealing effect can be generated either between the first and second element, first element and container and / or second element and container, preferably by pressing the sealing element between the respective sealing partners.

Advantageously, a cap is also provided for sealing, which preferably seals both the liquid channel and the return flow channel. This cap may in particular be suitable for reversibly closing the container after the first opening. In this case, the cap is advantageously designed such that it is fastened to the closure, in particular to the first or the second element, via a flexible element, for example a film hinge, and can thus easily be folded over the two channels. A closure of the two channels is necessary to ensure that even with not upright storage of the container no fluid can escape from the container. In this case, the cap or at least one coating of the cap and the flexible element, but at least the flexible element of an elastic material, such as polyethylene (PE) or the like can be made. Furthermore, various types of rubber such as styrene-butadiene rubber (SBR) or the like are conceivable, which have sufficient flexibility to allow pivoting of the cap.

The cap can advantageously be designed without its own safety mechanism. By a securing mechanism according to the invention eliminates the need to secure the cap against improper opening. As a result, the cap can be made simpler and less expensive and easier to open by the consumer.

Furthermore, a device for preventing tampering is particularly preferably arranged in the fluid channel and / or in the at least one return channel such that there is no free, essentially straight path from a pour opening or return opening to the sealing element. Particularly advantageously, the device for tamper protection on lateral openings and arranged for sealing element closed bottom and / or an overhang. The underside and / or overhang is, for example, a continuous or partially perforated surface, which is formed puncture-proof for syringes, for example. Through such a manipulation It is intended to reliably prevent the contents of the bottle from being manipulated from the outside, for example by means of a syringe, for which the sealing element is accessible through an opening in the closure. The lateral openings ensure that the fluid reaches the pouring opening after opening through the fluid channel.

Further advantages and embodiments will become apparent from the accompanying drawings.

FIG. 1 shows a three-dimensional view of the closure 1 according to the invention. Here, the first element 300 and the second element 100 are shown. Furthermore, the cap 110 is shown, which seals the second element 100 after the first opening. In addition, an example of a form of the control elements 140 is shown, which bend irreversibly at the first opening.

FIG. 2 shows a cross-sectional view of the closure according to a first embodiment. Here, the second element 100 is in the first position and the sealing element 202 is intact. In this figure, two locking pins 150 are provided, which hold the second element 100 relative to the first element 300 in the first position. Furthermore, a metering element 120 is provided above the fluid channel 160. Due to the fact that a closure according to the invention can have both a sealing element 202 and a metering element 120, a particularly high level of safety is achieved by the sealing element 202 with simultaneous ease of handling by the metering element 120. Adjacent to the fluid channel 160, a return channel 170 is provided in this embodiment. The sealing element 202 can in this case be held and clamped over a sealing ring 201. On the underside 163 and / or an overhang 164 (see FIGS. 6 or 9) of the second element 100, a cutting element 130 designed as a cutting edge can be provided. In addition, 300 locking lugs 180 are provided on the first element, in which, depending on the position, at least one of the locking pin 150 engages. In a preferred embodiment, the latching lugs 180 carry at least one latching bump 181. An inventive latching bump 181 generates a defined resistance in the displacement direction R. Thus, a user of the container also has a tactile and / or acoustic feedback on the first opening of the container.

Figure 3 is also a cross-sectional view of the closure. However, Figure 3 shows an alternative embodiment of the closure and is rotated 90 °. Here, the cutting element 130 may be formed as a mandrel and / or cutting edge, with which the Seal member 202 can be pierced. Furthermore, in this illustration, the control elements 140 can be seen, which bend at the first impressions. In addition, no locking lugs 180 can be seen for the locking pin 150. Also, the cap 110 is not visible in this illustration.

FIG. 4 corresponds to the cross-sectional view of FIG. 2. However, in this figure, the second element 100 is in the second position and the sealing element 202 is severed by the cutting element 130. FIG. 5 shows a three-dimensional view of an embodiment of the closure 1. The closure 1 has an opened cap 110, which is connected to the closure 1 via a flexible element 111, for example in the form of a film hinge. The illustrated closure 1 comprises a second element 100 which completely encloses a first element 300 of the closure 1 except for the side (not visible) facing the container B. A securing element 410 is attached to the second element 100 via a predetermined tear point 412. The illustrated securing element 410 encloses an opening (not visible) of the container B, which is closed by the closure 1, and has a grip element 411 in the form of a tab and a further predetermined tear point 412, whereby the securing element 410 can be torn off the closure 1 by a consumer , The additional predetermined tear point 412 avoids that the securing element 410 is prematurely or unintentionally torn off unnoticed by handling or the production-side closing process. The predetermined breaking points 412 can be formed radially zuglabil with respect to the axis A according to the invention. Figure 6 shows a longitudinal section through the closure 1 shown in Figure 5 in a first position corresponding to the delivery state of the filled container B except for the cap 110 shown opened. In this illustration, the opening O of the container B, which is closed by the shutter 1, visible. About the opening O is a sealing element 202, for example, a multi-layer sealing film, placed and sealed by the screwed with the aid of, for example, an internal thread 500 on an external thread 501 of the container B seal 1, for example, clamped. Likewise, a sealing fixation by cohesive connection, such as by gluing the sealing element 202 on the container B, for example by induction sealing, possible. The second element 100 of the closure 1 comprises a fluid channel 160 for removal a fluid from the container B, wherein the fluid channel 160 is connected via a lateral opening 162 with a spout opening 161. In addition to the spout opening 161, the second element 100 has a return channel opening 170, through which air can flow into the container B during the removal of the fluid. By latching lugs 180, the second element in a first position and latching pin 150 of the first member 300 of the closure 1 is held. The securing element 410 can likewise carry corresponding latching lugs (not shown), so that the closure 1 can not be pulled off the container B in a nondestructive manner, in particular not without tearing off the securing element 410 from the second element 100 at the predetermined tear point 412. An inventive securing element 410 can along the direction of displacement R have a sufficiently large extent, so that the securing element 410 is deformed upon displacement of the second element 100 from the first position to the second position by contact with the container B such that the fuse element 410 is irreversibly and visibly changed. Such a change can be made, in particular, in that the securing element 410 at the predetermined tear point 412 tears off the second element 100 at least in sections. As a result, the second element 100 can not be displaced from the first to the second position without the fuse element 410 being visibly irreversibly changed. The securing element 410 thus indicates to the consumer whether the second element 100 has already been manipulated, for example displaced into the second position, and thus the fluid in the container B has been intervened.

FIG. 7 shows a longitudinal section through the closure 1 shown in FIG. 5 in a second position. After the securing element 410 has been torn off, the second element 100 can be moved along a direction of displacement R against the first element 300 to the container B to from the first position to the second position. The cutting element 130 cuts through the sealing element 202 and pushes it aside, for example, so that a fluid can be removed from the container B through the fluid channel 160. Also in the second position, the second element 100 is held by latching lugs 180 on latching pin 150 of the first element 300. A positive connection between the latching lugs 180 and latching pin 150 prevents the second element 100 from being pushed back into the first position and thus prevents the risk of a leakage occurring inside the closure 1. FIG. 8 shows a cross-section through the closure 1 shown in FIG. 5. The first element 300 and the second element 100 enclosing the first element are connected to one another via a lock 510 which is formed by a number of driver ribs 511 and barrier ribs 512. In the example shown, three driver ribs 511 are arranged on an inner side of the first element 300 and three blocking ribs 512 complementary to the driver ribs 511 are arranged on an outer side of the second element 100. Due to the lock 510, the closure can be screwed to the container B by a torque acting on the second element, but not unscrewed therefrom.

FIG. 9 shows a cross-section through a closure 1 as shown in FIG. 5 with a securing element 410 bent at a predetermined bending point (not shown, position analogous to the predetermined breaking point 412) and displaced below the closure 1. The buckling is preferably visibly irreversible. In the illustrated bent state, the securing element 410 can, for example, interact positively and / or positively with the closure 1 and thereby additionally secure the second (use) position of the closure 1. Advantageously, the securing element 410 is mechanically decoupled from the first element 300, even in the bent state, so as not to transmit forces acting from outside to secure the sealing effect.
