- hermetically sealed containers such as hermetically sealed containers, vacuum-sealed containers, or pressurized containers.
- these types of containers are pressure-sealed vessels that may be useful for preserving certain properties of a product sealed inside. For instance, tennis balls are stored in pressurized containers to preserve the air pressure within the balls.
- Tennis balls are composed of a hollow rubber core with an outer felt material. They are pressurized with nitrogen or another gas, usually to about 14 psi, to obtain the proper bounce. Tennis balls are commonly contained in cylindrical plastic or metal pressurized containers having a top-end closure made of aluminum or tin sheet metal, which is provided with a tab for easy opening. The top-end closure with the tab may provide a removable pressure seal disposed over the top of the container.
- the flip-top tab When opening a tennis ball pressurized container, the flip-top tab is flipped forward to break the pressure seal and then the tab is used to pull off the pressure seal. When removed, the exposed outer edge around the perimeter of the pressure seal can be very sharp and creates a hazard to the user's fingers. Therefore, there is a need for an improved opening mechanism that preserves the sealing function of a sealed container and does not damage the removable lid while minimizing the risk of injury to a user of the container.

- the opening mechanism 102 can be reattached to the open top 126 of the vessel 124 without creating any substantial air gaps between the overhang 108 and the sides of the vessel 124 due to the cover 106 having a larger area than the open top 126 .
- the overhang 108 may have some curvature so that the overhang 108 curves toward the top edge and/or sides of the vessel 124 when the opening mechanism 102 is positioned over the top of the vessel.

Abstract
An improved and safer opening mechanism for a container, such as a pressurized container, is provided that includes a synchronous relationship between a safety cap and a sealable plate, such that the safety cap covers the sealable plate when it is removed from the container.
Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 16/874,775 entitled “Opening Mechanism for a Container,” filed May 15, 2020, which in turn claims the benefit of priority to U.S. Provisional Application No. 62/848,862, entitled “Opening Mechanism for a Pressurized Container,” filed May 16, 2019, both of which are hereby incorporated by reference in their entireties as if fully set forth herein.
- Embodiments of the present disclosure relate to sealed containers, and more specifically, to improved opening mechanisms for sealed containers, which may be safer and easier to open.
- There are various types of sealed containers, such as hermetically sealed containers, vacuum-sealed containers, or pressurized containers. Taking as an example the pressurized container, these types of containers are pressure-sealed vessels that may be useful for preserving certain properties of a product sealed inside. For instance, tennis balls are stored in pressurized containers to preserve the air pressure within the balls.
- Tennis balls are composed of a hollow rubber core with an outer felt material. They are pressurized with nitrogen or another gas, usually to about 14 psi, to obtain the proper bounce. Tennis balls are commonly contained in cylindrical plastic or metal pressurized containers having a top-end closure made of aluminum or tin sheet metal, which is provided with a tab for easy opening. The top-end closure with the tab may provide a removable pressure seal disposed over the top of the container.
- When opening a tennis ball pressurized container, the flip-top tab is flipped forward to break the pressure seal and then the tab is used to pull off the pressure seal. When removed, the exposed outer edge around the perimeter of the pressure seal can be very sharp and creates a hazard to the user's fingers. Therefore, there is a need for an improved opening mechanism that preserves the sealing function of a sealed container and does not damage the removable lid while minimizing the risk of injury to a user of the container.
- The presently disclosed opening mechanism for containers is directed to these and other objectives.
- Embodiments of the presently disclosed technology include a container comprising a vessel further comprising a top edge defining an open top of the vessel and a removable lid couplable about the top edge of the vessel. The removable lid can comprise a safety cover configured to conceal the open top of the container and comprising: (i) an overhang configured to receive the top edge of the vessel when the removable lid is coupled to the vessel; and (ii) an opening. The removable lid can also comprise a sealable plate disposed below the safety cover including a tab, and an adhesive bonding the sealable plate to the safety cover. The tab can extend through the opening of the safety cover, such that the tab is accessible from outside the safety cover.
- In some embodiments, when the container is unopened, the sealable plate can be joined to the vessel to preserve the pressure within the pressurized container and be separable from the vessel via a pressing seam disposed about the perimeter of the sealable plate.
- In some embodiments, when the tab is pulled with sufficient force to separate the sealable plate from the vessel about the pressing seam, the overhang of the safety cover can cover an exposed edge of the sealable plate.
- In some embodiments, the overhang can be disposed about the entire perimeter of the cover, such that the overhang covers the entire exposed edge of the sealable plate.
- In some embodiments, the area of the safety cover is greater than the area of the top of the vessel, e.g., bounded by a perimeter edge around the top of the vessel. For example, the safety cover may be generally circular shaped and have a diameter that is greater than a diameter (or longest diagonal) across the top of the vessel. For instance, if the vessel is a cylindrical tennis ball container having a diameter of around 2.7 inches defined by its top perimeter edge, the safety cover in some disclosed embodiments may comprise a circular area having a diameter of 3 inches, 3.25 inches, 3.5 inches, or greater, which is longer than the top diameter of the tennis ball container.
- In some embodiments where the area of the safety cover is greater than the area of the top of the vessel, the overhang of the safety cover may be angled inward toward the top edge of the vessel and/or sides of the vessel. For example, the overhang may be angled inward toward the top edge and/or sides of the vessel by, for example, around 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, or a greater angle relative to a normal direction extending perpendicularly from the area of the top of the vessel. As used herein, the “sides” of the vessel may comprise one or more sides defining the outer side surface(s) of the vessel. For example, the sides of a cylindrical vessel may correspond to an outer surface encircling the perimeter of the cylinder. In contrast, a vessel having a square-shaped cross-sectional area may have four distinct sides.
- In some embodiments, the overhang of the safety cover may have some curvature so that the overhang curves toward the top edge and/or sides of the vessel when the removable lid is positioned over the top of the vessel.
- In some embodiments, the overhang of the safety cover may contact the sides of the vessel when the removable lid is positioned over the top of the vessel. For example, the overhang of the safety cover may physically contact one or more sides of the vessel before the removable lid has been removed to open the vessel, and the overhang also may contact one or more the sides of the vessel after the removable lid has been removed and then replaced over the open top of the vessel.
- In some embodiments, the opening can be located proximate an outer edge of the top surface of the safety cover.
- In some embodiments, the tab can be affixed proximate an outer edge of the top surface of the sealable plate.
- In some embodiments, the safety cap can be made of at least one of a plastic or a rubber material.
- In some embodiments, the adhesive can be an epoxy resin.
- In some embodiments, the opening can be a key-hole shaped cut-out disposed within the cover.
- In some embodiments, the sealable plate can be composed of a metal.
- Another embodiment of the presently disclosed technology includes a removable lid system for a container. The removable lid system can comprise a safety cap comprising a cover, and an overhang disposed about a perimeter of the safety cap, the overhang configured to couple with a top edge of the container. The removal lid system can further comprise an opening disposed within the cover of the safety cap and comprise a sealable plate bonded, such as using an adhesive, below the cover and within the overhang of the safety cap, the sealable plate further comprising a tab member affixed to a top side of the sealable plate such that the tab extends through the opening of the safety cap and is accessible from above the safety cap. In some embodiments, when the container is unopened, the sealable plate may be joined to the container to preserve the pressure within the pressurized container, and when the tab is pulled with sufficient force to separate the sealable plate from the internal side wall of the container, the overhang of the safety cap can cover an exposed edge of the sealable plate.
- In some embodiments, the area of the cover may be greater than the area of the top of the container. In such embodiments, the overhang may be angled inwardly toward a top edge and/or sides of the container. In addition, the overhang may be configured to physically contact the top edge and/or sides of the container when the removable lid system is positioned over the top of the container. In some embodiments, the overhang may be configured to curve toward the top edge of the container and/or sides of the container when the removable lid system is positioned over the top of the container.

FIGS. 1-4 show an exemplary embodiment of acontainer 100 andopening mechanism 102, in accordance with the presently disclosed technology. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects. - The
opening mechanism 102 may be incorporated on any type of sealed container now known or later discovered. While explicit mention is made to tennis ball containers, this is meant to be as an example and is not in any way limiting on the scope of the disclosure, unless explicitly claimed. In some embodiments, these types of pressurized containers may be tennis ball containers, food or beverage containers, or other types of containers for which pressure is used to preserve the contents of the container. Additionally, in some embodiments, the container may be hermetically sealed or vacuum-sealed containers, such as traditional aluminum cans used in canning foods. The container contents may be liquids, solids, or gasses, and it is understood that the described opening mechanism may be used with any container regardless of its intended contents, or combinations thereof. -
FIGS. 1-4 illustrate an exemplary embodiment of acontainer 100 including an improved, easy-to-open, andsafer opening mechanism 102. Theopening mechanism 102 may comprise asafety cap 104, asealable plate 114, atab member 116, and an adhesive 120 which work synchronously to provide a safer opening mechanism. This synchronistic relationship between thesafety cap 104 andsealable plate 114 has not been appreciated prior to the presently disclosed technology. - The
container 100 comprises avessel 124 with anopen top 126 for receiving and storing contents within thecontainer 100. Thecontainer 100 may be any shape or size. In an exemplary embodiment, as illustrated inFIGS. 2A and 2B , thecontainer 100 may be cylindrical. Such a cylindrical container may be used to hold tennis balls, for instance. - The
safety cap 104 can comprise acover 106, anoverhang 108, and anopening 110. Thecover 106 may be located at a top-most portion of thesafety cap 104. When thesafety cap 104 is coupled to avessel 124, as illustrated inFIGS. 2A and 2B , thecover 106 is disposed above and covers theopen top 126 of thevessel 124 and the underlyingsealable plate 114. In some embodiments, thesafety cap 104 can be composed of a flexible material, such as a plastic or rubber. - In some embodiments, such as illustrated in
FIG. 1 , thecover 106 may be flat such that when theopening mechanism 102 is coupled to thecontainer 100, thecover 106 is disposed perpendicular to thecontainer 100. In other embodiments, thecover 106 may comprise a ridge (not shown) disposed about an outer portion of thecover 106. In some embodiments, the ridge may be disposed about the entire perimeter of thecover 106. - The
cover 106 can also comprise anopening 110. In some embodiments, theopening 110 is disposed within thecover 106, such that all boundaries of theopening 110 are within thecover 106. In other embodiments, less than all boundaries of theopening 110 are within thecover 106. In some embodiments, theopening 110 can be positioned offset from the center of thecover 106, as illustrated for instance inFIG. 1 , such that theopening 100 is proximate anouter edge 112 of thecover 106. - The
opening 110 may be any shape so as to accommodate thetab 116 being accessible from outside thecover 106 and through theopening 110. In an exemplary embodiment, theopening 110 can be key-hole shaped, such as that illustrated inFIGS. 3A and 3B . In other embodiments, theopening 110 can be approximately the same shape as thetab 116. - The
safety cap 104 can also comprise anoverhang 108. Theoverhang 108 can be an extension of thecover 106 that extends downwardly from thecover 106 such that theoverhang 108 may receive and couple to atop edge 128 of thevessel 124. In an exemplary embodiment, theoverhang 108 can be disposed about the entire perimeter of thesafety cap 104 and/orcover 106. This allows theoverhang 108 to protect the entire sharp portion of a removedsealable plate 114. - The
opening mechanism 102 also comprises asealable plate 114. Thesealable plate 114 can allow for sealing thecontainer 100 when it is unopened. In some embodiments, thesealable plate 114 can be a thin plate of a pliant metal material, such as tin or aluminum, that is ductile enough to allow the plate to flex when the seal is broken. - The
sealable plate 114 can also comprise atab 116 affixed to atop side 122 of thesealable plate 114. In some embodiments, thetab 116 can be positioned offset from a center of thesealable plate 114 such that thetab 116 can be affixed proximate an outer edge 118 of thesealable plate 114. Thus, thetab 116 can line up with theopening 110 of thesafety cap 104 such that thetab 116 is accessible from outside thesafety cap 104. Thetab 116 can be any type of structure (e.g., a ring) that can be pulled or manipulated by a human hand to remove thesealable plate 114 from thecontainer 100 and open thecontainer 100. In some embodiments, thetab 116 can be composed of the same material as thesealable plate 114. - When the
container 100 is unopened, thesealable plate 114 can be joined to thevessel 124. For instance, in some embodiments, thesealable plate 114 can be affixed to an internal side edge of thevessel 124. Thesealable plate 114 can be removable from thevessel 124 by pulling thetab 116 forward to break thesealable plate 114 along a pressing seam such that thesealable plate 114 can be removed upon pulling thetab 116 away from thesealable plate 114. - The
top surface 132 of thesealable plate 114 can be fused to abottom side 122 of thesafety cap 104 and/orcover 106. In some embodiments, thesealable plate 114 can be fused via an adhesive 120, such as an epoxy resin or hot-melt adhesive. Thebottom side 122 of thesafety cap 104 and/or cover 106 may be attached to top surface of thesealable plate 114 at one or more locations using any adhesives, bonding, fusing, welding, etc. or other suitable attachment means. - When a user goes to open the
container 100, the user can access thetab 116 from outside thesafety cap 104. Thesealable plate 114 can be separable from thevessel 124 via a pressing seal. Upon flipping thetab 116 forward, the pressing seal will break and theentire opening mechanism 102 can be removed. When theopening mechanism 102 is removed, theoverhang 108 of thesafety cap 104 will cover an exposed edge of thesealable plate 114 thereby decreasing risk of exposure to injury to a user. -
FIGS. 5A and 5B andFIG. 6 illustrate exemplary embodiments in which the surface area of thecover 106 is greater than the cross-sectional area at the top of thevessel 124. In these examples, the top surface of thecover 106 is generally circular. Similarly, the cross-sectional area at the top of thevessel 124 in these examples is also generally circular, e.g., having a circular open top 126. In these exemplary embodiments, the diameter ofcover 106 is greater than the diameter of the cross-sectional area at the top of thevessel 124. In other embodiments (not shown) where thevessel 124 may comprise a polygon or other non-circular cross-sectional area, the diameter of thecover 106 may be greater than the longest diagonal across the top of thevessel 124. - In the embodiments of
FIGS. 5A and 5B andFIG. 6 , because the diameter of thecover 106 is greater than the diameter of the top of thevessel 124, thecover 106 is therefore also wider than thesealable plate 114 that is joined to the top of thevessel 124 before theopening mechanism 102 is removed from thecontainer 100. Further, when a user removes theopening mechanism 102 using thetab 116, and thesealable plate 114 is removed with thecover 106 because it is attached (e.g., fused, bonded, etc.) to the bottom surface of thecover 106, the fact that the diameter of thecover 106 is greater than that of thesealable plate 114 provides additional spacing between theoverhang 108 being handled by the user and the sharp outer edge of thesealable plate 114 after it has been removed from thevessel 124. This added spacing provides further protection against the user contacting the sharp outer edge of thesealable plate 114 and decreases the risk of user injury. - In
FIGS. 5A and 5B andFIG. 6 , where thecover 106 is larger in area than the top of thevessel 124, theoverhang 108 may extend downwardly and inwardly toward thetop edge 128 of thevessel 124 and/or the sides of thevessel 124. For example, in some embodiments theoverhang 108 may extend downwardly from theouter edge 112 of thecover 106 and may be angled inwardly toward the top edge and/or sides of thevessel 124 by around 20 to 45 degrees or greater relative to a normal direction extending perpendicularly from the top of thevessel 124. By angling theoverhang 108 inwardly in this manner, theopening mechanism 102 can be reattached to theopen top 126 of thevessel 124 without creating any substantial air gaps between theoverhang 108 and the sides of thevessel 124 due to thecover 106 having a larger area than theopen top 126. - As shown in
FIGS. 5A and 5B , theoverhang 108 may have some curvature so that theoverhang 108 curves toward the top edge and/or sides of thevessel 124 when theopening mechanism 102 is positioned over the top of the vessel. In contrast,FIG. 6 illustrates an alternative embodiment in which theoverhang 108 comprises substantially straight sides. In either case, theoverhang 108 in the exemplary embodiments ofFIGS. 5A and 5B andFIG. 6 may make physical contact with the outer surface of thevessel 124 and/ortop edge 128 of thevessel 124 when theopening mechanism 102 is positioned over the top of the vessel, e.g., before theopening mechanism 102 has been removed to open thecontainer 100 and after theopening mechanism 102 has been replaced over theopen top 126 of thevessel 124. Such physical contact between theangled overhang 108 and thevessel 124 may provide a more secure attachment of theopening mechanism 102 to thecontainer 100, particularly when the opening mechanism is reused after having been removed by a user. - Numerous alterations of the structure herein disclosed will suggest themselves to those skilled in the art. However, it is to be understood that the present disclosure relates to an example embodiment of the presently disclosed technology which is for purposes of illustration only and not to be construed as a limitation of the presently disclosed technology. All such modifications which do not depart from the spirit of the presently disclosed technology are intended to be included within the scope of the appended claims.
