Description

DESCRIPTION

Closure for a container and container with such a closure

The present invention relates to a closure or closure device for a container and to a container provided with such a closure.

Said closure or dispensing device is especially used to dispense products contained in a container to which said closure or dispensing device is attached.

Usually, the products to be dispensed are fluid products, such as, for example, liquids or powdered or granulated products, for example, in the food or beverage area, but also in other applications, for example, for cleaning substances, detergents or other products.

The present invention relates especially to a closure having a hinged lid that is attached to a base element by means of a hinge, whereas said hinged lid can be moved between a fully open position and a fully closed position, while usually being rotated. essentially around a hinge between its open position and its closed position.

Such a product is known, for example, from US 7,051,888 B2.

An object of the present invention is to provide an improved closure or dispensing device with a base member and a hinged lid attached to said base member.

This object is achieved by a closure for a container according to claim 1 and a container with such a closure according to claim 14. Claims 2 to 13 refer to especially advantageous embodiments of the closure according to claim 1, claim 15 is a particularly advantageous embodiment of a container with such a closure according to claim 14.

According to the present invention, the closure for a container comprises a base element and a hinged lid which, directly or indirectly, are attached to said base element by means of a hinge. The connection of the hinged lid to the base element is made in such a way that the hinged lid can be moved between a fully open position and a fully closed position, the hinged lid being rotated, usually, between these two positions.

According to the invention, the base element has a skirt with joining means for joining the closure to the container, in which said skirt has an upper zone and a lower zone, the upper zone being closer to the hinged lid than said lower zone when said hinged lid is in its fully closed position.

The attachment means are suitable for attaching the closure element to a container, preferably to the neck of a container, for example a bottle, so that a product, usually a fluid product, for example a liquid or a powder product or granulate, may be dispensed from said container through said neck and through the closure, provided, of course, said flip-top lid is in its open position.

The closure has an orientation, with the bottom or side part attached to a container, especially the neck of a container, the upper part being defined by the opposite part of the closure, where the hinged lid is placed when in its closed position. Therefore, a vertical x-axis can be defined, extending, in a vertical direction, from top to bottom, through the closure.

Usually such closures have an essentially circular shape, as also the usual necks of containers are essentially circular, so that also the skirt of such a closure has an essentially cylindrical shape, the cylinder having an essentially circular cross section and being the vertical x-axis the longitudinal axis of said cylinder or of said essentially cylindrical shape.

Therefore, a direction normal or perpendicular to the vertical direction or the x-axis is defined as an inward or outward direction, also called a radial direction, even if the shape of the closure is not strictly circular. Therefore, an outward direction would be a direction normal to the vertical x-axis direction, from the inside of the closure to the outside of the closure, for example, starting from the x-axis, and normal or perpendicular to it.

In accordance with the present invention, the skirt of the base member has a tongue member that extends from the upper zone or an upper edge of said skirt in an upward direction or a vertically upward direction, that is, in an essentially parallel direction. to said vertical x axis.

In this regard, it should be noted that an extension of said tongue member in an ascending or vertically ascending direction occurs when said extension of said tongue member has at least one component extending in an ascending or vertically ascending direction. Therefore, it is also possible that the member tongue, in addition to extending in a vertically upward direction, it also extends in an inward or outward or radial direction.

The hinged lid in one disclosure of the present invention has a protrusion that extends outwardly or radially outward from said hinged lid in a direction that is normal or essentially normal to said ascending or vertically ascending direction or the direction of the x-axis, in which extends said tongue member. Also in this sense, it should be noted that the extension of the projection provides at least one component that is directed outwardly or radially outward, although it would be possible that the extension of that projection also partly had other components, for example, in a direction vertical, so that the protrusion did not necessarily have to extend only in a radially outward or outward direction, but could also partially extend in an upward or downward direction, so that the extension comprised components in both an outward and outward direction. in a vertical or x-axis direction.

In accordance with the present invention, said tab member and said protrusion are positioned and arranged in such a way that, during a movement of said hinged lid between its fully closed position and its fully open position, said protrusion and said tongue member are, in a first predetermined angular interval of the position of the hinged lid with respect to the base element during its movement between its fully closed position and its fully open position, in contact with each other in such a way that the projection exerts a force on said locking member. tongue in an inward or radially inward direction, while said tongue member exerts a counter force on said protrusion.

The amount of force and counterforce exerted can be set by the specific geometric structure and dimensions of, especially, the barb member, for example the thickness of the barb member, and can also be influenced and determined by the selection of the material used to the closure and especially the tongue member and its mechanical properties, eg, its stiffness and elasticity.

Said tongue member and said projection are positioned and arranged in such a way that, when said hinged lid is within a second predetermined angular range with respect to said base element, said counterforce supports a movement of said hinged lid in a direction towards its fully open position.

In a preferred embodiment, the first predetermined angular range, wherein said protrusion and said tab member are in contact with each other, extends in a range of about 70 ° to 190 °, preferably about 80 ° to 140 °.

The second predetermined angular range preferably extends from about 30 ° to 90 °, preferably from about 40 ° to 60 °.

In this regard, it should also be noted that in a case when said hinged lid is within a third predetermined angular interval with respect to said base element, which, essentially, is directly adjacent to the second predetermined angular interval, while both the second and the third predetermined angular interval are within the first predetermined angular interval, said counterforce can support a movement of said hinged lid in a direction towards its fully closed position.

In a preferred embodiment, there is a "neutral position" between said second and said third predetermined angular range, whereas, when the hinged lid is moved slightly towards the second predetermined angular range or the third predetermined angular range, the movement of said hinged lid in the range of its fully open position or in its fully closed position.

According to the present invention, said tab element or at least one outer surface thereof extends, in an upper part thereof, at least partially in an inward or radially inward direction.

A closure for a container according to the present invention has the advantage that the hinged lid, when in its open or fully open position, is efficiently held in this position, such that the hinged lid does not inadvertently move to its position. closed position or an intermediate position during use or during dispensing of a product contained in a corresponding container.

In addition, the device is especially easy to use, since, due to the force and counterforce created by said tongue member and said protrusion, there is direct feedback for the user, who automatically feels the force or counterforce when operating the lid. hinged so that the user receives automatic feedback as to when the hinged lid is in its fully open position.

An important advantage is obtained by the specific shape and geometric arrangement of said tab element or at least one outer surface thereof, preferably extending in an upper part thereof, at least partially in an inward direction or radially outward. inside, as this provides a uniform development of the force and counterforce created between said tab member and said protrusion, in such a way so that these forces do not change abruptly or with too high a gradient, thus ensuring that a smooth movement of the hinged lid is made from its closed position to its fully open position and vice versa, which especially avoids splashing or spilling of the product contained in a corresponding container, especially in those cases, where the product is a liquid product and especially for a first opening of the closure, when the corresponding container is still completely filled with a product, especially a liquid, to be dispensed.

Such controlled development of a force and a counterforce between the tongue member and the protrusion cannot be realized with a tongue member that essentially extends only in a vertical direction.

The exact development of force and counterforce between said tongue member and said protrusion can be precisely adjusted, also depending on the materials used for the manufacture of the closure, but always requires that the tongue member or at least an outer surface thereof extends at least partially in an inward or radially inward direction with respect to the initial position of said tongue member at the top or at the top edge of said skirt, or with respect to the outer surface of the skirt.

The extension in an inward or radially inward direction can begin already prior to a vertical extension of said tongue, for example, already at about 10% or 20% of the total vertical extension of the tongue element calculated from the upper part or upper edge of said skirt.

In one embodiment it is also possible that the tongue, extending from an upper portion or upper part or upper edge of said skirt, directly begins to flex or partially bend inward until said tongue element or an outer surface thereof has reached its maximum inwardly directed position, relative to the radial or inward / outward position of said skirt or the outer surface of said skirt.

The outer surface of said tab element has, in a preferred embodiment, a continuously developing shape or a continuously differentiable shape, that is, a shape without any edge, and may comprise convex and concave shapes, essentially showing the outer surface, in a specific embodiment, an S-shape or a partial S-shape. However, it should also be noted that in another embodiment it is also possible that the outer surface of the tab element comprises one or more edges.

In a preferred embodiment, the closure is arranged in such a way that an opening angle of said hinged lid between its fully closed position and its fully open position is at least equal to 180 °, being preferably greater than 180 °. This large opening angle especially ensures that the hinged lid does not interfere at all with the dispensing of any product when it is being dispensed, even if the user does not manipulate the device during dispensing perfectly, for example by tilting the container to which it is being dispensed. attached a closure in accordance with the present invention.

In a preferred embodiment, the hinge comprises two or at least two separate parts, which are arranged, in a circumferential direction of said closure, at a certain distance. These two parts of the hinge could be realized, for example, by means of two elastic blades connecting the hinged lid and the base element. Such a hinge is easy to manufacture, especially by injection molding, and provides reliable operation, closing and / or opening of the hinged lid. Preferably, the closure is arranged in such a way that it is also possible to mold the closure with the lid in a closed position.

In a preferred embodiment, the tongue member and said protrusion are positioned between such two parts of the hinge, for example between the two elastic sheets. Especially due to the fact that the tongue member and the protrusion exert a force and a counter force against each other, the specific embodiment leads to a stable and reliable operation of the closure, especially a stable and reliable movement of the hinged lid between its open position and its closed position.

According to another preferred embodiment, the tab member has a lower portion, which extends both in an upward direction and in an inward direction of the closure, preferably in a radially inward direction of the closure, since the closure is preferably a closure having an essentially circular shape with an essentially cylindrical or partially cylindrical skirt.

Preferably, the outer surface of said tab element is curved, preferably convex curved, which allows a smooth development of force and counterforce during the opening and closing of said hinged lid.

In a preferred embodiment, the upper part of the tongue member extends only in the vertical or upward direction.

In a preferred embodiment, the tab element and protrusion are arranged such that, during movement of the hinged lid from its fully closed position to its fully open position, the protrusion first abuts in an angular position. against an outer surface of said tab element, preferably in an area having the most outward or radially outward position, such that, when the hinged lid continues to move, especially rotating, in its fully open position, the tab member remains in contact with the outer surface of said tab member and moves along the length of the tab member such that it then comes into contact with a part of said tab member or an outer surface thereof that extends at least partially in a direction more inward.

In a preferred embodiment, an outer surface of said tab member has, in a lower portion thereof, a cross-section formed at least partially convexly, which preferably rotates, in a more upward direction, in a cross-section formed of concave manner, while, more preferably, at the uppermost part of the tongue member, the cross section of the outer surface of said tongue member is essentially linearly formed. This specific arrangement realizes a specifically smooth and preferred development of force and counterforce between the tab member and the projection during operation of the hinged lid and movement of the hinged lid between its open position and its closed position.

Preferably, the projection of the hinged lid is positioned on a top of the hinged lid and extends outwardly, preferably radially outward, while the expression "radially outward" is also used in cases where the hinged lid has a shape that deviates at least partially from a circular or cylindrical shape, for example when the closure has an oval or other shape.

According to a preferred embodiment, the angular extension of said protrusion and / or said tab member, in a circumferential direction of the closure, is in the area of about 10 ° to 40 °, more preferably 15 ° to 30 °, by For example, approximately 25 °, which, on the one hand, allows safe operation of the device and a safe and reliable interaction between the protrusion and the tongue member, while, on the other hand, keeps the elements small enough to use the less material is required and therefore also reduce the overall weight of the closure, which is a major cost factor for the manufacture of the closures.

In a preferred embodiment, the angular extensions of said projection and said tab member in a circumferential direction are essentially identical and overlap, in another preferred embodiment, however, the angular extension of said projection is less than the angular extension of said member. tab in a circumferential direction of the closure.

According to another preferred embodiment, the height of the skirt of said base element is different in its circumferential extension, the height of the skirt being, preferably, the greatest in a circumferential area where said tongue member and / or said projection are placed. This has the advantage that the protrusion and the tongue member are positioned in direct proximity to each other, which makes it possible to minimize the size of the protrusion and / or the tongue member, while maintaining high stability and therefore , a reliable interaction between these two elements during the closing operation. Preferably, the skirt has, on an opposite side thereof, the lowest height, which increases the overall size of the opening provided by the closure when said hinged lid is in its fully open position.

Preferably, the upper edge of the skirt extends continuously, that is, without any edge, which increases stability, while maintaining the advantages mentioned above, also providing an exceptional optical appearance of the closure, in addition to the functional advantages described. previously.

The present invention also relates to a container with a closure as described above, whereas the closure is preferably attached to said container, for example by screwing it to the neck of a container or by pressing the closure onto the neck of a container. Both the closure and the container, especially the neck of a container, therefore provide a fixing means that interacts with each other, these fixing means being able to be threads, for example an internal thread in a skirt of the base element of the closure and corresponding external threads on the neck of a container, although corresponding projections are also possible to make a so-called snap closure. It is also possible that the closure and the container or the closure and the neck of a container form an integral unit, being at least partially manufactured together or, alternatively, being connected to each other by other means, for example by gluing or welding.

According to a specifically preferred embodiment, the container, or especially the neck of the container, provides at least one projection, which extends at least partially around the circumference of, for example, the neck of a container, at a predetermined height of the container. neck, while said projection is arranged such that when said closure is attached to the container, the tab member extends in an inward or radially inward direction at a position (vertically) above said projection of said neck of said container. This specific embodiment has the advantage that also the projection of the neck supports and controls the development of the force and counterforce developed between the tongue and the projection, especially the counterforce of the tongue member.

These and other features and advantages of a closure or a container with a closure will also be described in relation to with the following description of an embodiment of a closure device according to the present invention: Figure 1 shows a perspective view of an embodiment of a closure of the present invention in its fully closed position;

Figure 2 shows a perspective view of the embodiment of Figure 1, in which the hinged lid is in its fully open position;

Figure 3 shows a cross section of the embodiment according to the present invention with the hinged lid in its fully closed position;

Figure 4 shows a cross section of the embodiment shown in Figure 3 with the hinged lid in a partially open position;

Figure 5 shows the embodiment shown in Figure 3 with the hinged lid in its fully open position; Figure 6 is an enlarged view of the embodiment shown in Figure 3 with the hinged lid in its fully closed position.

Figure 1 shows a perspective view of one embodiment of a closure 10 for a container in accordance with the present invention. The closure 10 comprises a base member 100 and a hinged lid 200, while the hinged lid 200, in Figure 1, is shown in its fully closed position.

The base element 100 comprises an essentially cylindrical skirt 110, which has, on its inner surface, a connecting means for joining the closure to a neck of the container, see especially Figure 3 described below.

The closure 10 also comprises a hinged lid 200, which is shown in its fully closed position, while the hinged lid 200 is attached to said base member 100 by means of a hinge 150.

The hinge 150 in this embodiment comprises two elastic blades 152, which are arranged at a distance from each other along the circumferential direction of the closure 10.

The base member 100 further comprises a tab member 120, which extends from an upper edge 160 of said skirt 110 in an upward direction, that is, in a direction parallel to a vertical, central or longitudinal axis, the x-axis which shown in figure 1.

Furthermore, the tab member 120 and its outer surface extend, in a part thereof, in an inward direction, which is shown and explained in more detail with respect to Fig. 3 below.

Flip-top 200 comprises a protrusion 220, extending outwardly from said flip-top 200 in a direction that is normal to said upward or vertical direction or x-axis direction, in which said tab member 120 extends.

Figure 2 shows another perspective view of the embodiment of the closure according to the invention shown in Figure 1, with the hinged lid in its fully open position.

As can be seen well in Figure 2, the opening angle of said hinged lid, for example, the angle around which the hinged lid 200 is rotated from its fully closed position to its fully open position, is notably greater than 180 ° , in the present invention, the opening angle being about 250 °, see, for example, also Figure 5 below.

The hinged lid 200 also comprises an inner ring 260, which is suitable for sealing the closure against the neck of a container, see especially Figure 3 below.

As can also be seen well in FIG. 2, the protrusion 220 of the flip top 100 and the tab member 120 of the base member 100 interact with each other such that the flip top 200 remains and is held in its fully open position. If the user wants to move or rotate the flip cover 200 out of its fully open position, as shown in Figure 2, in the direction of the closed position, the projection 220 is pressed against the outer surface of the tab member 120, such that a force is exerted on the tab member 120, thereby creating a counterforce, so that the user has to exert a greater force in order to move the flip top 200 out of its fully open position as would be the case. case if no tongue member or protrusion is present.

As mentioned above, the exact force can be set and adjusted, for example, by selecting a specific thickness of the elements, especially the tongue member, and selecting the material of the tongue member with respect to its mechanical properties.

As can also be seen well in Figure 2, the skirt 110 of the base element 100 comprises, on an inner surface of the skirt 110, a joining means 132 and 134, which are suitable for joining the closure to the neck of a container, as will be described below in connection with figure 3.

Figure 3 shows a cross section of the embodiment shown in Figures 1 and 2, the hinged lid 200 being in its fully closed position and the closure 10 being attached to a neck 300 of a container.

As can be seen well in Figure 3, the neck 300 of a container comprises an annular projection 330, which extends in an outward direction on the outer surface of the neck 300.

The skirt 110 of the base member 100 of the closure 200 comprises, on its inner surface, inwardly projecting fixing means 132 and 134, while the fixing means 132, comprising various projections, is positioned below the projection 330 of the neck 300, when the closure 10 is mounted on the neck 300 of the container, while the projection 134 of the skirt 100 is positioned above, or vertically above, the projection 330 of the neck 300 of the container.

In order to bring the closure 10 into its neck-mounted position, the closure 10 is pressed onto the neck 300 of the container, so that the embodiment shown here is a so-called snap closure.

In this regard, however, it should also be noted that it would also be possible to provide different fixing means. The closure could also be realized, for example, as a closure having internal threads that correspond to the external threads of the neck of a container, so that the closure can be screwed onto the neck of the container.

As can also be seen well in Figure 3, the inner ring 260 extending from a lower interior wall of the flip cap 200 fits into an opening defined by the neck 300 of the container, so that the flip cap 200 seals the opening of the container. neck 300 of the container when in its fully closed position.

Figure 4 shows the embodiment shown in Figure 3, also in cross section, however, with the hinged lid 200 in a partially open position.

As can be seen well in Figure 4, the projection 220 abuts against an outer surface of the tongue member 120, such that said projection 220 exerts a force on said tongue member 120, thereby generating a counter force.

Therefore, the user will have to exert a greater force in order to further move or rotate the flip cover 200 in the direction of its fully open position.

However, due to the fact that, as can also be well seen in Figure 4, the end of a projection 220 moves, with further rotation of the flip cover to its fully open position, in an area of the tab member 120 , which flexes or bends partially in an inward direction, the force and counterforce created between these two elements is gradually reduced from a certain predetermined angle of rotation.

This has the advantage that the hinged lid 200, on the one hand, will be pressed further into its fully open position, starting from a certain predetermined angle of rotation, the force being reduced, however, such that there is no "jolt." "Strong flip lid to its fully open position, preventing splashing or spilling of any liquid from the container.

Figure 5 shows the embodiment according to the present invention as shown in Figure 4, however, with the hinged lid in its fully open position.

As can be seen well in Figure 5, the protrusion 220 now essentially fully engages the area of the tab element 110, which is radially inwardly moving.

The specific shape of the tongue member 120 or the outer surface thereof therefore manages to provide adequate development of the force and counterforce created between the tongue element 120 and the projection 220, depending on the angle of rotation, of so that, on the one hand, the movement of the hinged lid 200 to its fully open position, after having reached a certain angular position, is supported and, especially, the hinged lid is held and retained in its fully open position, while which, on the other hand, prevents too strong a force from developing between these two elements, which would otherwise lead to an undesirably strong shaking of the hinged lid to its fully open position, as this frequently causes splashing or spillage of the contents of the container, especially in case the container comprises a liquid and in case the container is relatively full.

In this regard, it should also be noted that the closure in this embodiment is also performed essentially automatically, in such a way that the movement of the hinged lid 200 back to its closed position is supported when the user moves the hinged lid 200, from its fully open position, back in a certain angular position.

In other words, there is an angular position al, a "neutral position", while a slight movement to an angular position closer to the fully closed position leads to a support of the movement of the hinged lid 200 in the direction of its closed position. , whereas otherwise, as described above, a movement beyond this angular position a1 in the direction of its fully open position, leads to the effect that the movement of the hinged lid 200 to its fully open position is supported. open.

Figure 6 shows a partial enlargement of the embodiment shown in Figure 3, with the hinged lid 200 in its fully closed position.

In figure 6 the embodiment of the tongue member 120 can be seen especially well, which not only extends in an upward direction, but also has a section 122, in which said tongue member 120 also extends in an inward direction. , in this case a radially inward direction, with an end or top section 124, again only extending in an upward direction.

Therefore, the outer surface 126 of the tongue member 120 is curved and has, first, a partially convex shaped surface, which, when moved further up, transitions to a partially formed cross section. concave, before, in an upper zone 124, which extends essentially linearly or vertically. Therefore, the outer surface 126 of the tab member 120 essentially describes an S-shape or part of an S-shape.

In this embodiment, the thickness of the tongue member 120 is essentially constant, however, it would of course also be possible to have a tongue member with different thicknesses along its length.

It is apparent to the skilled person that various modifications can be made to the embodiment, without departing from the scope of the present invention, as defined in the appended claims, and any features described in connection with the embodiments or the general description may be important to realize the invention, either alone or any combination thereof.
