Definitions

  • the present invention relates to a two-part, child-resistant closure, in particular for containers, with a hollow body-like inner cap, which has a first closable with a lid, cylindrical, upwardly open shell portion and a second lower, downwardly open shell portion, and one at least partially the outer cap surrounding outer cap, wherein the outer cap has a central upwardly open recess through which at least a portion of the inner cap is at least partially feasible and which is deflected by application of force from a starting position in the direction of the central axis of the closure and after-termination of the application of force by at least a suspension is traceable back to the starting position.
  • hinged lid closures are known from the prior art, which find their use almost without exception in the food industry. Due to the easy and simple opening of such hinged lid, the contents, such as ketchup, mayonnaise or honey, can be quickly removed from the container. These closures, which can only be opened with a small amount of force, can thus be used only in areas in which the contents are edible or are not harmful to health when ingested or in contact with the skin. As soon as non-consumable or even harmful substances are used, for example, the Hazardous Substances Ordinance or EU directives, such as Directive 1999/45 eG, require a child-resistant closure which prevents children from being in unintentional contact with the contents and serious injuries, such as chemical burns, are the result. Conventional hinged lid closures are not suitable for this purpose due to the lack of parental control.
  • it is an object of the present invention after overcoming the child safety to ensure a simple, safe and fast opening of the closure and removal of the contents.
  • the present invention provides a closure which need not be removed from the container during product removal.
  • a further object of the present invention is to provide a closure which can be opened with one hand.
  • the present invention is based on the object cost and technically easy to manufacture and suitable for mass production.
  • the idea of the present invention consists in a two-part, child-resistant closure, consisting of an inner cap and an outer cap at least partially surrounding the inner cap, wherein the closure is easy to open after overcoming the child safety device.
  • the suspension comprises at least two band-like spring elements, which are arranged on the inside of the outer cap and each having an obliquely downwardly directed end. This is advantageous because the spring strength is adjustable by the obliquely downward arrangement of the spring elements. In addition, upon application of force to the spring elements, the acting force is better distributed and dissipated, so that the spring elements according to the invention are more stable and unbreakable than purely vertically arranged spring elements.
  • the spring elements according to the invention due to the formed slope with a higher force, preferred Compressive force to be acted upon and have a greater travel than is the case with purely vertically arranged spring elements. This requires according to the invention a longer life of the closure, since the bending stress is reduced to a minimum.
  • the band-like spring elements are rectilinear and require an inclined plane.
  • the band-like spring elements are at least partially helically wound. This is advantageous since, upon application of force to the outer cap, larger forces are thus absorbed by the spring elements along the central axis.
  • the spring travel is advantageously increased in comparison to known horizontally arranged ribbon-like spring elements, so that cracks and breaks of the spring elements are avoided due to overuse.
  • the at least partially helical curvature of the band-like spring elements according to the invention causes a quick return of the outer cap with the end of the application of force in its initial position.
  • the spring elements can be guided against the inner cap.
  • the band-like spring elements are preferably designed as compression spring elements. These are advantageous when pressurizing the outer cap along the central axis against a region of the inner cap, preferably against an arranged between upper and lower shell portion edge region, feasible, so that this area of the inner cap acts as a limiting means and the application of force to the spring elements itself is conditional. If the outer cap is acted upon by a pressure along the central axis, the free ends of the spring elements are guided free of force until they have a first contact area with the edge region of the inner cap.
  • the free ends of the spring elements are guided further against the edge region of the inner cap until a surface-like contact region between the free ends and the edge region of the inner cap is caused.
  • the spring elements are deformed and tensioned during further, sustained application of force.
  • the spring elements are deflected out of their starting position and guided in the direction of the inner wall of the upper cover surface of the outer cap. This requires a predeterminable force to clamp the spring elements according to the invention accordingly, which by material selection, material thickness and material flexibility the spring elements is adjustable. So short, thick spring elements require a greater amount of force to the voltage, as long, thin spring elements.
  • the free ends of the spring elements are designed such that in a closure according to the invention, consisting of an inner cap and an outer cap, each edge of a spring element with the underlying edge region of the inner cap a contact surface formed.
  • the respective free end has an end face, which is arranged in the force-free state parallel to an edge region of the inner cap.
  • the end face when force is applied, has a common contact surface with the edge region of the inner cap, which is preferably rectangular.
  • the end faces have a rectangular cross section, so that a rectangular, common contact surface between the respective end faces and the inner cap is required. This is particularly advantageous since thus the deformation of the spring elements is controlled and uniform and breakage or cracks in the spring elements is avoided.
  • the cross-section in any shape, such as round, oval or polygonal.
  • the outer cap at least partially with the suspension, which is preferably fixedly disposed on the inner cap, a common contact surface, preferably on the inner wall of the outer cap on.
  • the outer cap is thus held by the suspension in an output length, in which advantageously the closure is not open. If the outer cap experiences a force application along the central axis of the closure, in particular a pressurization, then the outer cap is deflected from its initial position and the inner wall of the outer cap is guided against the suspension.
  • the suspension which is not part of the invention, as a band-like spring elements, which also have a convex upward curvature, the force acting on the spring elements by the application of force is absorbed by the spring elements, and in particular led away laterally from the force application surface , so that cracks and fractures are avoided even with overuse of the spring elements.
  • the spring elements Depending on the configuration of the curvature, the spring elements have a more or less large spring travel.
  • the spring elements are connected at their ends to an edge region of the outer cap fixed thereto, for example as a fixed bearing. It is conceivable that the ends of the spring elements are arranged differently spaced from each other depending on the design at the edge region. This fixation requires the travel of the spring elements. If the spring elements are, for example, arc-shaped with an upwardly directed convex curvature and, in addition, the two ends of the arcuate spring element are arranged at a distance from one another at the edge region, then the spring travel of the spring element is greater under force application than at ends arranged directly adjacent to one another.
  • the outer cap By acting in the direction of the central axis of force application, the outer cap is deflected from its initial position, whereas the inner cap advantageously remains at rest. During this Kraftbeauschlagung thus the inner cap is at least partially carried out by an upward, centric opening of the outer cap, so that the lid of the inner cap can be preferably opened with one hand and the contents can be removed.
  • the spring elements are returned by the restoring force back to its original shape and position, whereby the outer cap is returned to its original position, so that the lid of the inner cap is no longer open.
  • the outer cap is advantageously free of resistance in its initial position, that is freely rotatable about the central axis of the closure, so that the closure for example, can not be opened by a screwing.
  • the spring elements are formed diamond-shaped with two upper diamond legs and two lower diamond legs, so that these spring elements advantageously have a convexly upwardly formed and two opposite, convexly formed to the side curvatures.
  • the lower diamond legs with their respective free end fixed to the inner cap, preferably spaced from each other, arranged.
  • a lower diamond leg and an upper diamond leg have a common contact surface.
  • the two upper diamond legs are firmly connected to each other via the convex upward curvature.
  • the diamond shape is particularly advantageous because the lower diamond legs of each spring element limit the deformation of the spring element when force is applied and determine the spring travel.
  • the lower diamond legs are thus advantageously less strongly deformed when force applied as the upper diamond legs, under deformation, the deflection of the diamond legs or the spring elements from their initial position, in which no force acts on them, is to be understood by applying force.
  • the upper diamond legs are deformed more than the lower diamond legs upon application of force at the point or area of greatest vertical extent toward the central axis of the closure.
  • the acting force is advantageously dissipated in the upper diamond legs.
  • After completion of the application of force causes the restoring force of the spring elements whose return to the starting position, whereby also on the spring elements at least partially resting outer cap is also returned to its original position.
  • the deformation can be controlled and targeted initiated.
  • the diamond-shaped configuration is advantageous, since thus no predetermined breaking point is caused by frequent application of force.
  • the spring elements are distorted diamond-shaped, so that the lower diamond legs are formed along its longitudinal direction shorter than the upper diamond legs along its longitudinal direction. This is advantageous if a high spring restoring force is desired, so that even after frequent application of force the spring elements automatically return to their original position and hardly any wear is caused.
  • the spring elements are arranged diametrically opposite each other on the inner cap. This is advantageous since the outer cap is thus uniformly absorbable in the direction of the center axis of the closure by force application and tilting or tilting of the outer cap is thus avoided.
  • the spring elements have an increasing cross section for their fixation on the inner cap. This is advantageous to adjust the travel and limit this.
  • the increasing cross-section which also causes an increasing wall thickness of the spring elements, in the lower region of the spring elements gives them an additional stability during the application of force and compression, so that breakage and crack formation are avoided.
  • these reinforced fixing areas also cause the advantageous provision of the field elements after termination of the application of force.
  • the spring elements are arranged at points of their greatest vertical extent above a plane which is spanned by an upper edge of the opening of the first cylindrical shell portion of the inner cap.
  • This arrangement is advantageous, since thus in the merged state of the closure, the outer cap at least partially rests in a region of its inner wall on the points or surfaces of the vertical largest extent of the spring elements, so that the upward, upper top surface of the outer cap and the upward Due to the at least partial support of the outer cap on the spring elements, the outer cap is held in accordance with their initial position and can not be deflected by children, which have a lower force, from its initial position, upper deck surface of the lid of the inner cap.
  • the closure of the invention is not open to children.
  • the upwardly directed top surface of the outer cap and the upwardly directed top surface of the lid are arranged radially spaced from each other, wherein the gap dimension is to be seen as a distance measure, which the radial distance between the top surface the outer cap and the top surface of the lid of the inner cap determined.
  • the gap dimension is selected such that when the closure is closed without force of the outer cap in the direction of the central axis of the closure, the lid of the inner cap is not open, not even for small children's fingers.
  • the second, lower shell portion of the inner cap on a sawtooth-like projection is preferably circumferentially arranged continuously on the lower shell portion.
  • the outwardly beveled projection is formed such that a complementarily trained, extending on the inner wall of the outer cap, further guide projection engages behind this. Outer cap and inner cap are thus fixed to each other, for example by means of a snap mechanism.
  • This sawtooth projection can thus serve to secure the outer cap against accidental detachment during the application of force or against unintentional release of the outer cap of the inner cap by children's hands.
  • the sawtooth projection of the inner cap and the latter engaging behind the guide projection of the outer cap can be designed such that when a Switzerlandbeetzung both caps are detachable from each other and thus also interchangeable. It is conceivable that different inner caps always form a two-part, child-resistant closure by means of one and the same type of outer caps. Under differently designed inner caps, for example, inner caps are to be understood, which have different tamper-evident elements, or which are formed differently from each other in the form of the cylindrical shell portion.
  • the releasability speed of the inner cap of the outer cap is formed such that the force of a child is not sufficient to overcome the sawtooth projection of the inner cap and separate the two caps from each other.
  • the child safety is guaranteed.
  • the inner cap has at least two diametrically opposed recesses in the lower shell portion.
  • these recesses are part of a locking mechanism, by means of which, with simultaneous opening possibility of the closure of the inner cap, the outer cap can be fixed in kraftbeaufschlagter position.
  • several such recesses are conceivable, such as two to ten, preferably two to six.
  • at least two such, diametrically opposed recesses are provided, since thus also a uniform fixation of the outer cap can take place while the spring elements are taut. If only one recess were provided, then the restoring force of the spring elements would cause an oblique return of the outer cap and the closure would not be open.
  • the recesses arbitrarily circumferentially in the lower shell portion, so that preferably two to ten such recesses are provided, wherein the distances of successive recesses may have the same and / or different distances from each other.
  • the recesses also advantageously serve to screw the closure according to the invention.

According to the invention, the cam-like projections also serve to screw the closure according to the invention.

  • the tubular element 58 is not limited to the described embodiment, but can also be used changeable in its geometric shape and, for example, have a polygonal cross-section.
  • both outer and inner diameter are to be chosen depending on the application and also not limited to the described exemplary embodiment.
  • the container is subdivided into a plurality of chambers, in order thus to provide a plurality of contents, and thus to cause a mixing of the individual, differing contents only upon removal.
  • the adapter-like element 24 is advantageously designed such that the lower portion 62 is subdivided into further separate regions, each of which can be equipped, for example, with a standpipe, from the individual chambers of the container, the corresponding contents, for example by the attachment of a syringe can be removed so that the different contents mix only in the hollow body of the syringe.
  • Barrier element (not shown) is advantageously provided in the third section 64, which prevents contents from leaking out of the container into the inner cap 2.
  • Such barrier elements can be designed, for example, as a valve or membrane, advantageously made of plastic.
  • Fig. 5 shows a conical outer cap 3, which is not part of the invention, having a peripheral outer surface 68, an upper top surface 70 and a circumferentially arranged end member 72.
  • the outer surface 68 may at least partially, more preferably entirely, gripping grooves 74 or not. These are preferably formed vertically in the direction of the central axis M. Further, it is conceivable to make the shape and the arrangement of the gripping grooves arbitrarily, for example, the particular determined by the arrangement of the gripping grooves 74 surfaces of the outer cap 3 are gripped by the user, so as to facilitate the opening of the closure.
  • the gripping grooves 74 may be formed, for example, in the direction of the center axis M, radially perpendicular to the central axis M or in preferably concentric circles or ellipses. In addition, it is conceivable that the gripping grooves 74 are arranged at variable distances from each other. It is also conceivable that the entire outer surface of the outer cap 3 has gripping grooves 74, other recesses or no depressions.
  • Fig. 6 is a partial sectional view of the outer cap 3 is shown.
  • the upper cover surface 70 is not continuous, but has a concentric, upwardly directed opening 76.
  • the inner diameter of this concentric opening 76 is formed such that the inner cap 2 described above (not shown) at least partially through this opening in the direction of the central axis M is feasible.
  • the inner wall 78 of the outer cap 3 has at the level of the end element 72 at least one, preferably a plurality of cam-like elements 80, which are advantageously arranged diametrically opposite one another. These cam-like elements 80 are formed complementary to the recesses 44 of the inner cap 2 and thus in this, for example by rotation, insertable. Furthermore, the inner wall 78 of the outer cap 3 has an at least partially radially encircling guide projection 82. This is preferably formed continuously radially, but may also be radially interrupted in the direction of the central axis M. Advantageously, the guide projection 82 is arranged on the inner wall 78 of the outer cap 3 at a height at which the outer shell surface 68 merges into a cylindrical shape from a conical shape widening downwardly in the direction of the central axis M.
  • Fig. 7 a schematic cross section of the outer cap 3 is shown, in which the guide projection 82 and its arrangement is shown. Identical components have the same reference numerals and will not be explained again here.
  • Fig. 8 is another embodiment of a closed, child-resistant closure 1 according to the invention with an inner cap 2 and an outer cap 3 arranged at least partially above it
  • Fig. 1 described closure example here the inner cap 2 in the assembled state in the direction of the central axis M is formed longer than the outer cap 3, so that the ring 48 protrudes at least partially below the closing element 72 in the direction of the central axis.
  • this described supernatant is formed so low that no margin is given, not even for small children's fingers, the outer cap 3 of the inner cap 2 to separate.
  • Such a closure design is advantageous if the container to be secured only has a short neck and thus the force application in the direction of the central axis M downwards in the direction of the container shoulder (not shown) is only partially possible.
  • a shortened in the direction of the central axis outer cap 3 is a convenient and extremely practical solution.
  • Fig. 9 is a spatial view of a closure, which is not part of the invention, shown, in which the outer cap 3 has been acted upon in the direction of arrow P on the upper deck surface 70 with an axial force.
  • the spring elements 30 a, 3 b undergo a deformation, so that the upper jacket section 4 projects at least partially from the concentric opening 76.
  • the spring elements 30a, 30b cause the return of the outer cap 3 in its initial position, so that the lid 10 can not be opened and is child-resistant closed.
  • the outer cap 3 is initially applied in the direction of arrow P down with a force.
  • the outer cap is deflected in the direction of arrow P until the cam-like elements 80 arranged on the inner wall 78 of the outer cap 3 come to rest on the upper peripheral edge 50 of the ring 48.
  • the outer cap is preferably rotated in a clockwise direction about the central axis M, so that the cam-like elements 80 can be introduced via a bevel into the recesses 44 and detachably fixed there.
  • this fixation of the outer cap 3 is formed on the inner cap 2 as a bayonet closure.
  • any type of closure can be used.
  • the outer cap After the product removal, the outer cap is rotated in the opposite direction, ie preferably counterclockwise about the central axis M and released from the recesses 44. Due to the restoring force of the spring elements 30a, 30b, the outer cap 3 is returned to its original position and the closure is closed childproof.
  • Fig. 10 shows a schematic cross-sectional view of an opened closure, which is not part of the invention. Same components as in the previous ones Fig. 1 to 9 have the same reference numerals and will not be explained again.
  • the lid 10 of the inner cap 2 is open.
  • the cam-like elements 80 which are arranged on the inner wall 78 of the outer cap 3, are releasably fixed in the complementary formed recesses 44 of the inner cap 2, so that the outer cap 3 is held in its deflected position.
  • the spring elements 30a, 30b are compressed and are thus under tension.
  • Fig. 11 shows a further embodiment of an inner cap 84, which is not part of the invention, which with the in Fig. 2 described inner cap 2 except for the formation of the suspension 30, which are shown here by the spring elements 86a, 86b, is identical.
  • the spring elements 86a, 86b are arc-shaped in this example and have a convex curvature upwards. Further, the spring elements 86a, 86b are also curved in their radial course convexly outwardly, so that both are arranged at the respective points of their highest vertical configuration furthest apart. This arcuate geometry of the spring elements 86a, 86b requires a favorable force absorption under application of force.
  • FIG. 12a Figure 3 is a perspective view of a closure 1, not part of the invention, which is open and in which a syringe 88 is inserted.
  • a syringe 88 In the lower area a arranged on the inner cap 2 riser 90 is shown.
  • Fig. 12b is a cross section of in Fig. 12a shown arrangement, wherein the inner cap 2 has a fixedly arranged adapter-like element 24. This represents either the male or the female tapered connection.
  • a closure 1 according to the invention with a female adapter-like element 24 is required, so that the first section 60 as inner cone trained and inserted into the male section of the spray nozzle or vice versa. Due to this interaction of the two precisely fitting areas, a reversible closure is required, so that the contents are controlled and can be removed from the container with almost no loss.
  • the closure 1 of the invention allows a simplified mounting of the syringe 88 and a safe overhead application, as can not escape through the one-piece inner cap 2 filling next to the designated opening and the risk of tilting is no longer present in overhead applications of large volume bottles.
  • the syringe nozzle 92 is releasably disposed within the first portion 60 of the tubular member 58.
  • the riser 90 is fixed, so that by loading the syringe plunger 94, the contents of the container (not shown) via the adapter-like element 24 can be removed without a difficult overhead application is required. Due to the advantageous embodiment of the closure contents can be removed easily and without loss.
  • Fig. 13 shows a spatial cross-sectional view of another outer cap 96, which is not part of the invention.
  • This has, in addition to the already described components such as guide projection 80, a plurality of cam-like elements 82 and the upwardly directed central opening 78, a suspension 98.
  • the suspension 98 is advantageously made of plastic, but could be formed of metal.
  • the suspension on the inside of the outer cap 3 is arranged such that it has a free, obliquely downwardly directed end and has a rectangular cross-section.
  • the cross section of the suspension 98 is designed to be decreasing toward its free end.
  • several such suspensions 98 are provided, more preferably two or four diametrically opposite each other.
  • 96 Upon application of force in the direction of the central axis M, the free ends of the suspension 98 are at least partially guided against the inner cap 2, whereby the suspension 98 experiences a tension. After the end of the application of force the spring restoring force returns the spring 98 and the outer cap 96 back to the starting position and the lid 10 of the inner cap 2 (not shown) is child-resistant closed.
  • 96 also modaliano elements may be arranged, for example in the arrow shape as in Fig. 13 shown, which indicate the user the direction of movement of the outer cap 3, 96.
  • Fig. 14 shows a schematic cross section of in Fig. 13 illustrated outer cap 96, which is not part of the invention, wherein like components have the same reference numerals and will not be explained again.
  • the outer cap 96 comprises, in addition to the cam-like projections 80 and the guide projection 82, further spring elements 98 which are fixedly arranged on the inner wall of the upper cover surface 70.
  • the spring elements 98 are band-like and each have an obliquely downwardly directed free end 100.
  • the free end 100 has an end face 102, which is here, but not in the context of the invention, as an edge.
  • the spring elements 98 are formed at least partially helically twisted and have along the central axis M a directed towards the inner wall 78 curvature K on. This is advantageous, since thus the pressure force introduced into the spring elements 98 can be distributed better.
  • the spring elements 98 are designed in such a way that they are arranged so as to be contact-free with respect to a plane spanned by the guide projection 82, thus having no common contact surface or sectional surface with this plane.
  • Fig. 15 shows an embodiment of an outer cap 96 according to the invention similar to that in FIG. 1, wherein like reference numerals correspond to like components and will not be explained again here.
  • the free ends 100 of the spring elements 98 each have an end face 102, which is aligned substantially horizontally in the force-free state.
  • This is advantageous because the common contact area between the end surface 102 and the edge region 28 of the inner cap (not shown) is thus enlarged, as if the end surface 102 were formed merely as an edge, as in FIG Fig. 14 is provided.
  • the end faces 102 of the spring elements 98 are guided under force against the edge region 28 and describe with further application of force an at least partially curved, preferably at least partially circular, web on the edge region 28 of the inner cap (not shown).
  • the free ends 100 of the spring elements 98 thus perform by the application of force on the edge region 28 a sliding movement and are thus deflected laterally from its original starting position.
