DETAILED DESCRIPTION
With reference now to the drawings, and in particular to FIGS. 1 through 8 thereof, a new reclosable container closure for a container embodying the principles and concepts of the disclosed subject matter will be described.
One aspect of the disclosure relates to a reclosable container system 10 that broadly includes a container 12 and a closure assembly 14 for the container. The disclosure also relates to aspects of the closure assembly 14 apart from the container.
In greater detail, the container 12 of the system 10 may include a container body 16 that has an interior 18 for receiving a fluid, such as a medicinal solution, although the container may be used to hold other types of liquids. The container body 16 has an opening 20 into the interior, and may include a mouth portion 22 that forms the opening 20. An outer surface 24 of the mouth portion 22 may have a plurality of exterior threads formed thereon for removable attachment of the closure assembly 14, although other removable and non-removable types of attachment may be utilized for attaching the closure system to the container. One optional configuration will be described below.
The closure assembly 14 may thus be removably mounted on the container 12 in the manner that permits separation of the closure assembly and container without damage or destruction to the closure assembly or container, may be more permanently mounted on the container 12 such that separation requires damage or destruction to the container or closure assembly. The closure assembly 14 may define an aperture 30 through which contents of the interior 18 of the container body is accessible.
The closure assembly 14 may comprise a base 32 that is mounted (either removably or more permanently) on the container 12. The base 32 may include a perimeter 34 with a top 36 and a bottom 38. The perimeter 34 may also have an outer surface 40 and an inner surface 42. A portion of the inner surface 42 of the perimeter may have a plurality of interior threads 44 formed thereon for engaging the exterior threads of the mouth portion 22 of the container. In the illustrative embodiments in the drawings, the perimeter 34 comprises a perimeter wall 46 having an upper edge 48 and a lower edge 49.
The base 32 may further comprise a separator 50 which may have the aperture 30 formed therein. The separator 50 may have an inner face 52 that is directed toward the interior 18 of the container body 16, and an outer face 54 that is directed outwardly from the interior 18, and the aperture may extend from the inner face to the outer face. The aperture 30 may thus be formed by a channel with some degree of length. The inner face 52 may be substantially concave in shape, although that is not critical. The aperture 30 may be positioned at the peak 56 of the concave inner face 52. The outer face 54 may be substantially planar in shape, although again the shape is not critical to the function. In the illustrative embodiments, the separator 50 may comprise a first separator wall 58 that extends across the perimeter 34, and may be joined to the perimeter along a perimeter region 60 of the first separator wall, and may form the concave inner face 52 of the separator 50. The illustrative separator 50 may further comprise a second separator wall 62 that extends across the perimeter 34. The second separator wall 62 may be joined to the perimeter 34 along a perimeter region 64 of the second separator wall, and may form the outer face 54 of the separator 50.
The base 32 may also include a valve 66 that is positioned on the separator 50 and may extend across the aperture 30 in the separator. In some preferred embodiment, the valve 66 may be opened by the application of pressure on the surface of the valve 66, such as by the pressing or pushing of a pointed object, such as the end of an oral syringe utilized for the oral administration of medicines. The valve 66 may be self-closable upon removal of the pressure from the valve, so that, for example, when the tip of the syringe is withdrawn from the valve, the opening closes and the contents of the container is resisted from passing through the valve. The valve 66 may have any suitable construction for this purpose, and illustratively comprises one, and optionally two, flexible and resilient membranes 68, 69 with small slits 67 formed therein that may be opened by the application of a narrow object to the membrane adjacent to the slit. In some embodiments, a pair of membranes 68, 69 overlap with the respective slits oriented so that the slits cross each other but do not align with each other except at the intersection. In some embodiments, the slit in each membrane has an “X-shaped” configuration, and these X-shaped slits may also be out of alignment so that they do not register with each other (although may intersect), but the sections of the membrane formed by the slits are able to be deflected away from each other to create an opening when force is applied to the sections of flexible membrane. This configuration of the valve is illustrative, and variations of this configuration, as well as other configurations, may be employed.
The closure assembly 14 may further have a cover 70 for selectively covering the aperture 30. The cover 70 may be mounted on the base 32, and may be movable with respect to the base between a closed position in which the aperture is not accessible and an open position in which the aperture is accessible. The cover may have many different but suitable configuration for serving the purpose of covering the aperture, and the covers described herein are to be considered illustrative but not limiting of the types of covers that may be devised for use. The cover 70 may be mounted on the perimeter 34 of the base, and may be pivotable with respect to the perimeter through a pivotable mounting on the perimeter. The cover 70 has a perimeter region 72, and a portion of the perimeter region may be mounted to the perimeter wall. The pivotable mounting may be provided in any suitable manner, such as by a hinge, and in the illustrative embodiments the connection is provided by a living hinge 78 formed of a flexible web of material connecting the cover 70 to the perimeter 34. The cover 70 may also be characterized by having a top side 74 and a bottom side 75.
The cover 70 may have a plug structure 76 for providing some degree of fluid tightness to the closure assembly in addition to the valve 66 when the cover is in the closed position. The plug structure 76 may be located on the bottom side of the cover 70 to extend outwardly from the bottom side, so that the plug structure may be partially inserted into the aperture 30 in the separator 50 when the cover is closed. The plug structure 76 may be an integral portion of the same part that forms the cover, or may be a part that is attached to the part or parts that forms the cover.
The closure assembly 14 may further include a locking structure 80 that is configured to releasably lock the cover 70 in the closed position. The locking structure may take various suitable, forms, and these forms may or may not be “child-proof”. In the illustrative embodiments, the locking structure 80 includes at least one, and preferably a pair of, tabs 82, 83 that extend from the cover 70 to engage the base 32 when the cover is in the closed position and to resist, but not prevent, movement of the cover from the closed to the open position. The tabs 82, 83 may be positioned on the bottom side 75 of the cover 70 to extend toward the separator 50 when the cover 70 is in the closed position. The tabs 82, 83 may also have a hook 84 located adjacent to a free end of the tab for engaging the separator, as will be described in greater detail below.
The locking structure 80 may also include at least one, and preferably a pair of, openings 86, 87 formed on the separator 50. The openings 86, 87 of the pair may be located on opposite sides of the aperture 30, and each tab of the pair of tabs may be suitably aligned with one of the openings when the cover 70 is in the closed position such that the tabs are inserted into the openings when the cover is in the closed position. The openings 86, 87 may be located on the separator 50 such that the hook 84 on each tab engages an edge of the separator about the respective openings when the tabs 82, 83 are inserted into the openings. In the illustrative embodiments, the opening 86, 87 are formed in the second separator wall 62 of the separator.
In some embodiments, the base 32 of the closure assembly is configured and constructed such that application of a pinching force to the base releases the hooks 84 of the tabs from the edge of the respective openings 86, 87. Application of the pinching force to the outer surface 40 of the perimeter 34 distorts the second separator wall 62 and causes the openings to move with respect to the hooks on the tabs so that the tabs and hooks are able to move out of the respective openings without being blocked by the edge of the openings.
In an optional embodiment of the closure assembly, indicated by the reference number 100, the base 102 has a perimeter 104 that is designed to be inserted into the interior of the mouth portion 22, of the container body 16. The perimeter 104 may have an outer surface 106 that is configured for insertion into an interior of the mouth portion 22 of the container, and in some embodiments the outer surface is substantially smooth and cylindrical, although other configurations may be employed. The perimeter 104 may include a positioning lip 108, and the positioning lip may extend outwardly from the perimeter wall 110 of the perimeter. The positioning lip 108 may be positioned at a top of the perimeter wall 110. The positioning lip 108 may prevent the base from being inserted too far into the mouth portion 22 of the container body 16, so that the base does not move past the interior of the mouth portion and move into the interior of the main portion of the container body 16. A cover 112 may be configured fit over the mouth portion 22 of the container body, and may be configured with interior threads 114 to engage exterior threads located on an outer surface 24 of the mouth portion 22 of the container, although other means for removably mounting the cover 112 on the container may be employed. The cover 112 may be free of any connection to the perimeter 104 such that the cover 112 is freely rotatable with respect to the container 12 and the base 102. In other embodiments, the cover 112 may be connected to the base 102 in the manner described above or using other structures.
The closure assembly 100 may also include any of the elements described in connection with the closure assembly 10, and may thus include a separator 116 that is mounted on and extends across the perimeter 104. An aperture 118 may be formed in the separator 116. A valve 120 may be positioned on the separator 116, and may extend across the aperture 118 in the separator. The valve may be a single valve, or comprise an assembly of two or more valves.
In use, the user of the system 10 is able to access the contents of the container, such as a medicinal fluid to be administered orally to a young child using an oral syringe, by means of the closure assembly 14, while being able to reclose the closure assembly after the access to the fluid so that the contents of the container 12 may be repeatedly accessed and a dose dispensed until the container is empty. The cover 70 of the closure assembly may be opened to expose and gain access to the aperture 30. In some embodiments, opening the cover 70 involves pinching opposite sides of the perimeter 34 of the base 32 toward each other to release the tabs 82, 83 from the edges of the openings 86, 87 in the base. The container system may be inverted to bring the contents of the interior 18 of the container body 16 toward the closure assembly and the aperture 30. The tip or end of a syringe, such as an oral syringe, may be inserted into the valve 66 of the closure assembly so that the tip of the syringe passes through the valve 66 and is surrounded by the contents of the container. Fluid may then be withdrawn from the container into the syringe, and the tip of the syringe is withdrawn from the valve and the aperture when a desired amount is drawn into the syringe. The container system may then be brought right side up, and the cover moved from the open position to the closed position until the next withdrawal of fluid is desired.
It should be appreciated from the foregoing description that, except when mutually exclusive, the features of the various embodiments described herein may be combined with features of other embodiments as desired while remaining within the intended scope of the disclosure.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the disclosed embodiments and implementations, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art in light of the foregoing disclosure, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosed subject matter to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to that fall within the scope of the claims.
