Description




FIELD OF THE INVENTION




The present invention relates generally to container lids, and more particularly relates to doors provided in container lids.




BACKGROUND OF THE INVENTION




Containers are used for a plethora of goods, including organic or perishable items such as food or spices. The conventional lid for a spice container contains an array of small holes for dispensing the small sized contents, typically in the form of powders or small particles, while a door is operable to cover and reveal the array of dispensing holes. It is desirable to have an easy-to-open door, and one such door commonly used with spice containers is a double-hinged door. This type of door generally comprises two different sections hinged together, one of those sections being hinged to the lid. The structure of the lid beneath the door is designed such that pressing downwardly on the door section hinged to the lid causes the other door section to flip upwardly revealing the array of dispensing holes.




While the door should be easy opening, the contents need to be properly sealed to preserve the integrity of the contents since they are organic. Thus, it is common for the underside of a door portion to include pegs which are sized and spaced to engage the array of holes and individually seal each hole. These peg and hole pairs do hinder the opening of the door to a certain degree, but are not prohibitive. More particularly, as the flip section rotates, the peg and hole pairs closest to the hinged connection of the door sections are the last to become unsealed, and hence the flip section is at a substantial angle as are its pegs. Thus, the pegs are usually bent while at least partially within the hole, requiring increased force to open and close the door.




Unfortunately, these lids are unable to dispense products that are not intended to be shaken out of the container. A person must turn the container upside down or at least sideways to dispense product, which is not suitable for all types of products. Similarly, one cannot reach into the container to remove items, whether or not they are capable of being shaken out of the container. Moreover, these containers and lids are generally in a very controlled environment, such as a shelf or cupboard, where inadvertent opening of the door is unlikely. Even so, clean up is usually not a problem. It will be recognized that there are numerous other environments in which small containers are used that are not as hospitable, and are less controlled such that inadvertent opening of the container is more likely. For example, inadvertent opening is more likely in a person's pocket or their bag where the environment is more volatile, and is not a place where spills are easily cleaned or otherwise dealt with. Therefore, there exists a need for a container lid that can dispense the contents without shaking or turning the container upside down, and which also protects from inadvertent opening in a more hostile and less controlled environment.




BRIEF SUMMARY OF THE INVENTION




In light of the above, it is a general aim of the present invention to provide a container lid having a double hinged door covering a large dispensing hole, the door being operable to reliably seal the hole and protect the contents of the container.




In that regard, it is an object of the present invention to provide such a lid having a dispensing hole that allows a person to retrieve items from the container by directly grasping or pinching the items rather than shaking them.




It is a further object of the present invention to prevent inadvertent opening the door and breaking of the seal.




In accordance with these objects, the present invention provides a lid for a container comprising a main body having a recess. The recess includes a first portion and a second portion separated by a pivot wall. A door is sized to be received within the recess, the door comprising a flip section pivotally connected to a push section, the push section pivotally connected to the main body. The flip section is positioned to engage the pivot wall and rotate towards the push section in response to downward pressure on the push section. The first portion of the recess has a dispensing hole for dispensing product, the dispensing hole preferably covering an area at least 0.9 square inches. Finally, an underside of the flip section of the door includes a sealing ring projecting downwardly, the sealing ring sized to correspond with the dispensing hole to provide a seal. This construction uniquely preserves the contents of the container while providing a larger hole suitable for other methods of retrieving the contents of the container.




According to more detailed aspects of the present embodiment, the dispensing hole more preferably covers an area at least 1.25 square inches and is sized to accommodate at least two human fingers. Most preferably, the dispensing hole covers at least 2.0 square inches. The sealing ring extends around the outer periphery of the flip section, while the dispensing hole covers a majority of the first portion of the recess.




According to another embodiment of the present invention, a container lid is provided generally comprising a main body having a recess. The recess includes a first portion and a second portion separated by a pivot wall, the first and second portions each having a floor. A door is sized to be received within the recess, the door comprising a flip section pivotally connected to a push section, the push section pivotally connected to the main body. The flip section is positioned to engage the pivot wall and rotate towards the push section in response to downward pressure on the push section. The first portion of the recess includes a dispensing hole for dispensing product, the dispensing hole covering at least 75% of the first portion of the recess. An underside of the flip section of the door has a sealing ring projecting downwardly, the sealing ring sized to correspond with the dispensing hole to provide a seal. More preferably, the dispensing hole covers at least 85% and most preferably 95% of the first recess portion.




According to more detailed aspects of the present embodiment, the main body is divided into a first body portion and a second body portion, the first body portion containing the first recess portion and the second body portion containing the second recess portion. Preferably, dispensing hole covers at least 70% of the first body portion, and more preferably covers at least 75% and most preferably at least 80% of the first body portion. In terms of the entire closure, the dispensing hole preferably covers at least 20% of the total area of the closure, more preferably 30% and most preferably 40%.




According to a further embodiment of the present invention, a lid for a container having organic goods is provided generally comprising a main body having a recess. The recess includes a first portion and a second portion separated by a pivot wall, the first and second portions each having side walls and a floor. A door is sized to be received within the recess, the door comprising a flip section pivotally connected to a push section, the push section pivotally connected to the main body. The flip section is positioned to engage the pivot wall and rotate from a closed position to an open position in response to downward pressure on the push section. The first portion of the recess has a dispensing hole for dispensing product, and an underside of the flip section of the door has a sealing ring projecting downwardly. The sealing ring is sized to correspond with the dispensing hole to provide a seal when the flip section of the door is in a closed position. Further, a detent is located in the push section to positively position the push section in its closed position and prevent inadvertent opening of the flip section. Preferably, the detent comprises a at least one tab and at least one notch, the tab formed in one of the push section and the side wall of the second recess portion, and the notch formed in the other one of the push section and the side wall of the second recess portion. Alternately the detent may comprise a pin and socket or a tongue and groove. Most preferably, the lid includes an additional notch vertically spaced from the first notch, so that the tab positioned to sequentially engage the two notches. The sealing ring of the flip section frictionally engages the main body in the closed position to securely position the flip section, while the detent securely positions the push section in the closed position.











Other objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




Referring now to the drawings,

FIGS. 1-8

illustrate one embodiment of the present invention. The general structure and operation of the present invention will be described in reference to these figures. Then, a few of the many alternate embodiments of the present invention will be described with reference to

FIGS. 9-15

. All of the figures depict a container and lid assembly, although the present invention is directed primarily towards the lid portion of the assembly.




With reference to

FIGS. 1 and 4

, a container and lid assembly


20


is depicted and generally comprises a cylindrical container


25


and a round and generally planar lid


30


. The lid


30


of the present invention generally comprises a main body


31


and a door


60


. The main body


31


includes a radiused outer peripheral edge


32


and a downwardly depending skirt


33


which engages the upper edge of the container


25


. The door


60


generally comprises a push section


61


pivotally connected to a flip section


62


by a hinge


63


. The hinge


63


is preferably a living hinge integrally formed with each of the push and flip sections


61


,


62


. The push section


61


is pivotally connected to the main body


31


via another living hinge


64


integrally formed with the outer peripheral edge


32


. Hinge


64


is also a living hinge and comprises a thin strip of flexible material and maintains the radius of the outer peripheral edge


32


, i.e., the hinge


64


is generally flush with the outer peripheral edge


32


, both vertically and horizontally. It will also be recognized that the hinge


64


may also project, typically horizontally, from the outer periphery of the edge


32


and container


25


, as is known in the art.




As illustrated in

FIGS. 2

,


5


and

FIGS. 3

,


6


, the double hinged lid


30


is structured such that the door


60


is easily and positively actuated.

FIGS. 2 and 5

illustrate the door


60


in an open position. In response to downward pressure or force on the push section


61


, the flip section


62


rotates upwardly and towards the push section


61


about hinge


63


. Stated another way, the flip section


62


has rotated away from the main body


31


. Preferably, the push section


61


includes an indication of where to press on the lid


30


and its door


60


, such as the bullseye


69


shown in the figures. In the closed position depicted in

FIGS. 1 and 4

, the push section


61


and flip section


62


were generally parallel to one another. In the state depicted in

FIGS. 2 and 5

, the lid has rotated to an open position, that position preferably being less than or equal to 90 degrees rotated relative to the main body


31


. Most preferably, the flip section


62


rotates in the range of 45 to 90 degrees from the main body in the open position. The position of hinge


63


relative to pivot wall


40


, as well as the depth of the recess


34


(best seen in

FIGS. 3 and 6

and further described below) are controlled to regulate the rotation of the flip section


62


as described above.





FIGS. 3 and 6

depict the lid


30


having its door


60


in an as-molded state. In this condition, the push section


61


has rotated relative to the main body about hinge


64


. The main body


31


includes a recess


34


generally comprising a first portion


35


and a second portion


36


. The first portion


35


is sized to receive the push portion


61


of the door


60


. The first portion


35


of the recess


34


is defined by a pivot wall


40


and a rear wall


43


connecting a pair of opposing side walls


41


,


42


. The push section


61


is hingedly connected to the main body


30


adjacent the rear wall


33


. The flip section


62


includes a nub


66


that allows the flip portion


62


of the door


60


to frictionally and securely engage the main body


31


of the lid


30


in the closed position. The main body


31


may include a corresponding groove (not shown) to receive and engage the nub


66


.




The second portion


36


of the recess


34


is sized to correspond with the flip section


62


of the door


60


. In the floor of the second portion


36


of the recess


34


, there is defined a large dispensing hole


37


for gaining access to the contents of the container. In fact, the hole is large enough to accommodate at least two fingers of a person retrieving contents of the container. Thus the hole is preferably sized to have an area of at least 0.9 in


2


, more preferably at least 1.25 in


2


, and most preferably at least 2.0 in


2


. The second portion


36


of the recess


34


and the dispensing hole


37


define a ledge


38


for supporting the outer periphery of the flip section


62


. Additionally, the flip section


62


preferably contains a sealing ring


65


projecting downwardly from an underside of the flip section


62


. The sealing ring


65


has a smooth unbarbed periphery which is sized to correspond with the dispensing hole


37


and frictionally engages the inner periphery of the hole


37


to effectively seal the contents of the container


25


. Therefore, the lid


20


not only allows a person to grasp product in the container with their fingers, but also effectively seals the dispensing hole


37


to protect products such as organics or perishable items.




As best seen in

FIGS. 7 and 7



a


, the inner periphery of the dispensing holes


37


preferably includes a seal flange


39


which extends around the entire periphery of the hole. The seal flange


39


is located at a downward edge of the inner periphery of the dispensing hole


37


. The seal flange


39


is used to provide an extremely reliable and effective hermetic seal to protect the contents of the container. The seal flange


39


is small enough (about 0.01 inches wide and tapering from 0.002 inches to 0.005 inches tall) and is of a material such as plastic which will deflect. More specifically, the flange


39


is resiliently deflectable so that when the door


60


is placed in its closed position, specifically the flip section


62


of the door, the sealing ring


65


which is sized to correspond with the dispensing hole


37


will engage the top tapered surface of the seal flange


39


and force it to deflect it generally downwardly against the sealing ring


65


. Accordingly, the sealing ring


65


engages not only the inner periphery of the dispensing hole


37


, but also the sealing flange


39


which will deflect slightly to ensure a secure engagement, thereby providing a reliable hermetic seal.




The seal ring


65


, preferably including the seal flange


39


, also operate to protect the door


60


from inadvertent opening. It will be recognized by those skilled in the art that when the door


60


is closed and a seal is formed by the seal ring


65


, that seal also frictionally restricts the opening of the door


60


, and more specifically the flip section


62


of the door. Additionally, the detent mechanism


80


controls the opening of the push section


61


, and hence restricts the opening of the flip portion


62


and inadvertent opening of the door


60


generally. As previously noted, the flip portion


62


also includes a nub


66


(

FIG. 3

) that is structured so that the flip portion


62


of the door


60


frictionally and securely engages the main body


31


in the closed position. All of these features, either alone or in some combination, operate to provide means for keeping the door


60


in its closed position.




At the same time, the lid


20


, and particularly its dispensing hole


37


, is structured and oriented to maximize the size of the hole. The recess


34


includes first and second portions


35


,


36


and also includes a floor


44


. The floor in the area of the second portion


36


has been largely removed to define the dispensing hole


37


. In fact, a very small strip of material is left to define the ledge


38


for supporting the outer periphery of the flip section


62


. Preferably, the dispensing hole


37


covers at least 75% of the second portion


36


of the recess


34


. More preferably the dispensing hole covers 85%, and most preferably 95% of the second recess portion. In the embodiment illustrated, the radius of the curved portion of the dispensing hole


37


is 1.17 inches, while the radius of the curved portion of the second recess portion


36


is about 1.2 inches. The radius of the outer edge of the lid is about 1.35 inches. Thus, in the illustrated embodiment, the dispensing hole


37


covers about 95% of the area corresponding to the second recess portion


36


. It can therefore be seen that the lid


20


provides a large, maximized opening while also reliably protecting the door


60


from inadvertent opening and breaking of the seal.




The provision of a large dispensing hole


37


and the ability to reliably seal and keep the door closed can also be thought of in terms of maximizing the use of the lid


20


. For example, the dispensing hole preferably covers at least 70% of the second body portion, more preferably at least 75% and most preferably 80% of the second body portion. In terms of the entire closure, the dispensing hole covers at least 20% of the total are of the closure, more preferably 30% and most preferably 40%.




The amount of space available within the container for the contents has also been maximized. It can be seen in

FIGS. 7 and 8



d


that the floor


44


of the recess


34


is sloped. Preferably, a first portion of the floor


45


, representing a majority of the floor, is angled to slope downwardly and inwardly from a position adjacent the rear wall


43


and the hinge


64


. The remaining portion of the floor


46


is generally flat or horizontal. Preferably, a substantial portion of the floor of the recess is angled downwardly and inwardly. The angled portion


45


of the floor


44


serves several purposes. First, the structure eliminates unused space to create increased holding capacity in the container


25


. The angled floor portion


45


also limits the flexure of the push section


61


, thereby increasing its life under repeated stresses. It can be seen in

FIG. 7

that the push section


61


is disposed proximate the angled portion


45


of the floor


44


when in the open position, corresponding to a first open position of the flip section


62


. Since the angles of the push section


61


and angled floor portion


45


are somewhat similar, the angled floor portion


45


being angled relative main body


31


slightly more than the push section


61


is angled, the amount of flexure in the push portion


61


is very limited.




With reference to

FIGS. 6

,


7


and


8




a


-


8




d


, the positive acting and controlled opening of the door


30


will be described in more detail. The lid


30


contains a detent mechanism


80


to control the opening of the door


60


. The location of the hinge


63


connecting the push section


61


and flip section


62


is selected such that downward pressure on the push section


61


causes the flip section


62


to engage the pivot wall


40


. As the push section


61


rotated downwardly into the first recessed portion


35


, the flip section


62


rotates upwardly, away from the main body


31


and towards the push section


61


. The detent mechanism


80


controls this opening, and in the preferred embodiment comprises a pair of notches


48


,


49


(

FIGS. 7 and 8



a


) formed in each opposing side wall


41


,


42


of the recess


34


, and more particularly the first portion


35


of the recess


34


. The push section


61


of the door


60


includes a tab


68


(

FIGS. 6 and 8



a


) on each opposing side positioned to correspond with the pair of notches


48


,


49


. Each tab


68


is positioned to sequentially engage the two notches


48


,


49


in the respective side wall


41


,


42


. The detent mechanism may also be reversed with the notches on the door and the tabs on the side walls.




The detent mechanism


80


controls the opening of the door


60


in at least two stages, as represented in

FIGS. 8



a


and


8




b


. In the first stage, the detent mechanism


80


substantially fixes the push section


61


in a closed position. In the second stage, the detent mechanism substantially fixes the push section in an open position. More specifically, in the closed position (depicted in

FIGS. 1 and 4

) the tabs


68


of the push section


61


engage the upper notch


48


as shown in

FIG. 8



a


, thereby positioning the flip section


62


in a position generally parallel with the push section


61


and the main body


31


. The detent mechanism


80


thus prevents inadvertent opening of the door


60


. In response to downward pressure on the push section


61


, the tabs


68


disengage the upper notches


48


and move downwardly until the are positively positioned within the lower notches


49


as shown in

FIG. 8



b


. In this open position of the push section


61


, the flip section


62


has engaged the pivot wall


41


and rotated towards the push section


61


to its open position. With the flip section


62


in the open position, access to the container


25


is possible through the dispensing hole


37


, and the door


60


may be completely moved by merely grasping either section of the door and causing the push section


61


to rotate relative to the main body


31


about its hinge


64


. The push section


61


is thus selectively operable between at least two locked positions corresponding to open and closed positions of the flip section


62


(

FIGS. 1 and 4

, and FIGS.


2


and


5


).




With reference to

FIGS. 8



c


and


8




d


, the detent mechanism


80


may further comprise additional notches corresponding to additional stages or stages of open positions of the door


60


. In

FIGS. 8



c


and


8




d


, a third notch


50


is positioned adjacent the first and second notches


48


,


49


, all of which are vertically spaced. In this embodiment, the door


60


starts in a closed position (

FIG. 8



a


) wherein the push section


61


is generally horizontal having its tabs


68


engaging the upper notch


48


. Upon a downward pressure, the push section


61


disengages the upper notch


48


and then rotates downwardly to engage the middle notch


50


. In this position, namely a partially open position (

FIG. 8



c


), the flip section


62


has rotated a much smaller amount than as depicted in

FIG. 7

, due to the additional detent. Preferably, the partially open position corresponds with an angle of 0 to 45 degrees, as is shown in

FIG. 8



d


. Upon further pressure on the push section


61


, the tabs


68


disengage the middle notch


50


and move to the lower notch


49


. This stage corresponds to a fully open position (FIGS.


2


and


5


), wherein the flip section


62


has rotated more than in the partially open position, as can be seen from the open position shown in FIG.


7


. In this fully open position, the flip section


62


has preferably rotated relative to the main body


31


about 45 to 90 degrees, most preferably less than 90 degrees.




It will be recognized by those skilled in the art that any number of detents, i.e. notches, can be utilized to stage or otherwise effectively control the opening of the double hinged door


60


. It will also be recognized that the multiple staged opening as depicted in the embodiment of

FIGS. 8



c


and


8




d


, can be effectuated with only two notches. To accomplish this, the position of the upper notch


48


must be closely regulated. The flip section


62


of the door frictionally engages the main body


31


, typically via the nub


66


and/or the sealing ring


65


. The amount of downward pressure on the push section


61


to disengage the tabs


68


from the upper notches


48


can be regulated such that the downward pressure causes the flip section


62


to disengage from its frictional engagement with the main body


31


prior to the tabs


68


disengaging the upper notches


48


. In this way, the flip section


62


may be rotated upward slightly, generally corresponding with the closed or partially open position (i.e. 0 to 45 degrees). Furthermore, this allows the entire door


60


to be placed in the as-molded position (as depicted in

FIGS. 3 and 6

) without causing the tabs


68


to disengage the upper notch


48


and move downwardly to engage the lower notch


49


, before the entire door


60


may be placed in the as-molded position. However, in the preferred embodiment, the notches


48
