Abstract
A container for providing a waterproof interior includes a container body and a lid. The container body has an interior, an interior perimeter that defines an opening, and a top exterior surface. The lid is made up of an interior plate and an overmold of material that surrounds the interior plate. The overmold has a seal ring and an overhang for engaging the container body and forming a water tight seal therewith. The lid is removeably from the container body, but when the lid is engaged to the container body, the lid covers the opening such that the overhang is engaged to the top exterior surface and the seal ring is engaged to the interior perimeter.

FIG. 7 is a sectional view of an embodiment of the waterproof container and the internal and external pressure effects that act on the container. - As illustrated in
FIG. 1-7 , the subject of the present disclosure is acontainer 10 for providing a sealed waterproofinterior space 12 into which any of a variety of objects, such as for example an electronic device may be deposited therein and protected from environmental conditions outside 14 of thecontainer 10. - Though the
container 10 may be of any size or shape, in the embodiments shown herein, thecontainer 10 is a simple two-piece, rectangular box comprising acontainer body 16, and a lid orcover 20 that in the closed state (as shown inFIGS. 1-2 ) has aseal ring 22 which engages aninterior perimeter 18 of thecontainer body 16. Atop portion 24 of thelid 20 includes anoverhang 26 which also engages the top exterior surface oredge 28 of thecontainer body 16. -
Container body 16 may be constructed from any suitable material for providing a waterproof environment. Suitable materials include, but are not limited to: plastic(s), resin(s), metal(s) or any combination thereof. In some embodiments, thecontainer body 16 is constructed of a material suitable for also providing impact protection (in addition to a waterproof interior environment), and thus the material from which thecontainer body 16 is constructed must have sufficient material strength to protect not only thecontainer body 16 from breakage but also any object contained therein. - Depending on the intended environment of use and/or the nature of the object(s) that the
container 10 is intended to protect within theinterior 12, the size and shape of thecontainer body 16 may be varied as well. The container may be of a size and shape sufficient to contain and protect relatively small objects such as a smart phone or other personal electronic devices, or may be configured to contain larger objects such as a lap top computer, important documents or files, or any other objects or substances that it may be desirous to contain in a waterproof environment. - As best illustrated in
FIG. 3 , thelid 20 has a size and shape which corresponds to the size and shape of the container body opening 30 as defined by theperimeter 18 and theedge 28 of thecontainer body 16; whereby theseal ring 22 of the lid engages theperimeter 18 and theoverhang 26 engages theedge 28 to completely cover and seal the opening 30 regardless of its size and shape. - As illustrated in
FIGS. 4 and 5 , thelid 20 has a two-piece construction consisting of aninternal plate 32 of metal or other compressionresistant material 34; and an overmold 36 of a relativelysoft material 38 that surrounds theplate 32 and which includes and forms theseal ring 22 and overhang 26. - When the
lid 20 is placed fitted on and into thecontainer body 16 in the manner shown inFIGS. 1-2, and 6-7 , theseal ring 22 frictionally engages theinside perimeter 18 of thecontainer body 16 to form a first component of the water tight seal between thecontainer body 16 and thelid 20. - To form the seal the overmold 36 is provided with a uniform thickness of
soft material 38. In some embodiments, an example of which is shown inFIG. 6 , thematerial 38 forms atop portion 24, asidewall portion 25 and abottom portion 27 of which each has a thickness ofsoft material 38 that is substantially equal as measured from the nearest surface of theplate 32. - In the embodiment shown for example, the
thickness 24′ of thetop portion 24 is between about 1.0 mm to about 3.0 mm, thethickness 25′ of thesidewall portion 25 is also between about 1.0 mm to about 3.0 mm, and thethickness 27′ of thebottom portion 27 is similarly between about 1.0 mm to about 3.0 mm. Theseal ring 22 extends outwardly from thesidewall portion 25 and has athickness 22′ of about 0.3 to about 0.5 mm. - When the
lid 20 is engaged to thecontainer body 16 theseal ring 22 is biased between theplate 32 and theperimeter 18 of thecontainer body 16. The uniform thickness of thesidewall portion 25 and theseal ring 22 allows the seal ring to be compressed by about 10% to about 30% from its unengaged state (open) to its engaged state (closed) effectively sandwiched between theplate 32 andperimeter 18 to form a water tight seal between the lid and container body without the need for an additional compressive force such as might be supplied by the use of fasteners or threading the lid against the container body. - To provide for the desired degree of compression necessary to form the water tight seal, the overmold
material 38 is selected from any type of flexible material suitable for forming a water tight barrier. In at least on embodiment thematerial 38 is made up at least partially of silicone or silicone rubber. In at least one embodiment the overmoldmaterial 38 is at least partially manufactured from a thermoplastic elastomer (TPE), a thermoplastic polyurethane (TPU), natural rubber, Nitrile, and/or any combination thereof. In at least one embodiment the overmoldmaterial 38 has a durometer hardness within the range of about 30 shore A to 80 shore A. - As is shown in
FIG. 7 , the interaction of thelid 20 with thecontainer body 16 involves some small volume of displaced air within thecontainer interior 12 as thelid 20 is pushed downward to engage thecontainer body 16. In order for the water tight seal to be achieved therebetween, it is required to overcome a small amount of resistance represented by the difference in pressure between thecontainer interior 12 and the outside 14. As the interior pressure (represented by arrows 40) of the air inside thecontainer body 16 naturally pushes against thelid 20 as it is being pushed into place, theseal ring 22 is forced to compress or otherwise displace to release a small amount of air from theinside 12 of thecontainer 10 to equalize theinterior pressure 40 with that of the outside pressure (represented by arrows 42). This equalized pressure, along with the frictional engagement of theseal ring 22 between the plate and 32 andperimeter 18, ensures the maintenance of the water tight seal between thelid 20 andcontainer body 16. - To remove the
lid 20 from the container, body the reverse process must occur. In order to aid in removal of thelid 20 from thecontainer body 16, the overmold 36 includes angrasping structure 44 such as a tab of protruding overmoldmaterial 38 that extends from theoverhang 26 and which may be of any size or shape suitable to allow a user to grasp or grip theengagement structure 44 when removing thelid 20 from thecontainer body 16. - In some embodiments, the
container 10, and more specifically thelid 20 may include direction or alignment features to ensure that the lid is properly aligned with thecontainer body 16 and more importantly with objects that the container may be custom built to contain and engage. In the embodiment shown for example one to threedirection cavities 46 are provided in thelid 20. Thesecavities 46 extend at least through thebottom thickness 27 of the overmold 36 and may extend at least partially through theplate 32. Nocavity 46 may extend through the entire thickness of thelid 20 for the sake of the water tight seal. - Even in embodiments where the
lid 20 and container body have no deed for alignment or engagement functionality as provided by the cavity orcavities 46, such features may be present as an artifact of fixing theplate 32 during the application of the overmold 36 - The many features and advantages of the invention are apparent from the above description. Numerous modifications and variations will readily occur to those skilled in the art. Since such modifications are possible, the invention is not to be limited to the exact construction and operation illustrated and described. Rather, the present invention should be limited only by the following claims.
