- The present invention relates generally to an airtight container, particularly a container used for storing vegetables and/or salad having an airtight lid, and more particular to a lid for use with an airtight salad bowl container that prevents involuntary opening.
- (2) Description of the Related Art
- In general, salad bowl containers used in cooking mixed or seasoned dishes such as salad, etc. have relatively large volume and a substantially circular shape. Although such salad bowl containers have been used in cooking, they typically have not been used for the purpose of storing food.
- Food is generally stored in separate airtight containers after it is cooked or needs to be stored. Using separate containers brings about several inconveniences such as needing additional and unnecessary containers and increasing the amount of containers to be washed.
- Airtight salad bowl containers as shown in
FIG. 1 orFIG. 4 are distributed in the market. The airtightsalad bowl container 101 is comprised of a semi-sphere shaped main body having an upward opening and alid 120 that forms an airtight seal of the upward opening of the main body of the container. - The main body of the container is structured with
sealing section 111 having upward protrusion in the rim of the top part andwing connection part 112 around the exterior rim section of the upward opening. -
Lid 120 is structured withgasket slit 121 accommodatingsealing gasket 123 in the rim section on the bottom and lockingwing 125 is locked and unlocked to thewing connection part 112 on the edge of the rim in the main body of the container defining small intervals along the circumference. -
Lid 120 defines a structure of circular plane as illustrated inFIG. 1 andFIG. 2 or a plane of circular arc as illustrated inFIG. 3 &FIG. 4 . - The main bodies of such containers without the
lid 120 are used in cooking mixed or seasoned dishes such as salad. Food is stored by blocking the upward opening of the main body of the container withlid 120 without the use of separate containers.Locking wing 125 is maintained to be locked to thewing connection part 112 of the main body of the container and a space between the main body of the container and thelid 120 is sealed airtight with sealinggasket 123. - Since previous airtight salad bowl container have lids in the shape of circular plate or plane of circular arc as shown in
FIG. 2 andFIG. 4 , it is inevitable for the rim of the lid to become unfastened upward when downward pressure is applied to the center of the lid. A problem exists where the lids open with involuntary unlocking of the locking wing fastened to the wing connection part of the main body of the container when a user drops the airtight container or unintentionally applies downward pressure to the lid. - Despite efforts to date, a need remains for an effective lid for use with an airtight container, particularly a container designated for use in cooking and storage of food such as salad which does not break a formed airtight seal when undergoing unintentional and involuntary forces such as being dropped or downward pressure.
- Therefore, it is an object of the present invention to provide a lid of an airtight container that does not open involuntarily during a fall or application of downward pressure to the lid.
- The present disclosure provides for a lid for use in an airtight container comprising: (a) center section; (b) a subsiding center section surrounding the center section and extending outwardly therefrom; (c) a rim reinforcing section surrounding the subsiding section and extending outwardly therefrom; (d) a lid rim surrounding the rim reinforcing section and extending outwardly therefrom, the lid rim being adapted to form a seal with a container rim defined on the airtight container; and (e) at least two locking wings mounted on the lid rim adapted to engage with a wing connection part extending outwardly along an exterior of the container rim such that the lid defines a locked and unlocked configuration with respect to the container. The lid rim and the container rim form a spatial interval sized to allow for upward, downward and circular movement of the lid with respect to the container. The lid protrudes upwardly in a sectional configuration extending from the rim to the center section.
- In an exemplary embodiment, the center section of the container is formed in either a curved surface or plane. In a further embodiment, the subsiding center section is formed in a subsiding circular arc plane. The subsiding center section can be formed to completely surrounding the center section. Further still, the subsiding center section can be formed in separated interval sections surrounding the center section. In a further embodiment, the rim reinforcing section is formed in either a curved surface or a tilted plane. In an exemplary embodiment, the lid further comprises a handle having opposed ends bonded in boundaries between the subsiding center section and the center section for circular movement. The handle is accommodated in the subsiding center section. In an exemplary embodiment, the lid is constructed to make operable distribution of an external force applied to the lid from the lid to the rim reinforcing section and increasing a locking force formed by the locking wings.
- In an exemplary embodiment, the lid further comprises a handle having opposed ends positioned in the center subsiding section. Further still, the handle can be positioned in the center subsiding section operable to allow for circular movement of the handle within the center subsiding section.

- With reference to the figures,
FIG. 5 illustrates a lid of an exemplary airtight salad bowl container according to the present invention.Lid 1 comprisescontainer blocking section 10 that opens and closes the upward opening of a main body of an exemplary container 40 (shown inFIG. 6 ). The rim of thecontainer blocking section 10 includes the lockingwing 21 that is locked and unlocked to thewing connection section 31 of the main body of the container and handle 30 is placed on thecontainer blocking section 10 of thelid 1.Container blocking section 10 is sized to cover the upward opening of main body ofcontainer 40 and constructed to define an overall upward protrusion from rim to center in sectional projection.Center section 11, subsidingcenter section 13 andrim reinforcing section 15 each define distinctive shape from the center to the exterior rim. -
Center section 11 can be formed in either a curved surface or plane surface. Preferably, subsidingcenter section 13 is formed around thecenter section 11 in a subsiding circular arc plane. In particular embodiments, thesubsiding center section 11 defines subsiding spaced apart intervals that are relatively smallsurrounding center section 11 as illustrated inFIG. 7 .Subsiding center section 13 may have subsiding structure with various plane shapes in section projection other than the subsiding circular arc. - Rim reinforcing section can be formed surrounding the subsiding center section as a curved surface. In a particular embodiment, the rim reinforcing section may be formed to define a tilted plane along a straight line in sectional projection. The
rim reinforcing section 15 can include a gasket slit 17 on a bottom side that accommodates sealinggasket 19 formed along and underneath the lid rim. -
Lid 1 is constructed and made operable to distribute force when applied to the lid in such a manner to prevent the force to be applied to therim reinforcing section 15 oflid 1. The center section and center subsiding section are constructed to adsorb the external force, such as downward pressure applied from the top of thelid 1, and redirect the direction of the external force. In addition, each of lockingwing 20 is formed in an edge of the rim of thecontainer blocking section 10 to allow for upward, downward, and circular movement. Lockingwing 20 includes lockingmaintenance parts 21 formed along a side toward a wing connection part (31) of the main body ofcontainer 40. The lockingwing 20 includes apressure control panel 23 with outward protrusion so that a user can apply pressure to the panel by holding the panel in an upward and downward direction. Lockingwing 20 maintains the main body ofcontainer 40 airtight withlid 1. A user can apply a downward pressure to pressurecontrol panel 23 thereby locking the lockingmaintenance part 21 to thewing connection part 31 of the main body ofcontainer 40 in a configuration wherelid 1 is covering the upward opening of the main body ofcontainer 40.Lid 1 can be separated from the main body of container (4) when a user applies upward pressure to pressurecontrol panel 23 thus separating the lockingmaintenance part 21 from thewing connection part 31 of the main body ofcontainer 40. Accordingly, upward pressure is applied to the panel when the main body ofcontainer 40 is sealed airtight with lid 1 (i.e., the condition where lockingmaintenance part 21 of the lockingwing 21 is fastened to thewing connection part 31 of the main body of container 40). - In an exemplary embodiment, a lid according to the present invention comprises a
handle 30 formed in a semi-circle such that opposed ends are bonded in boundaries between subsidingcenter section 13 and thecenter section 11.Handle 30 can improve convenience in storage and exterior of theairtight container 40 by accommodating thehandle 30 within subsidingcenter section 13 allowing for circular movement in an embodiment where subsidingcenter section 13 oflid 1 is formed to entirely surroundcenter section 111. In an alternative embodiment, as shown inFIG. 7 , handle 30 defines a structure that is accommodated within thesubsiding center section 13 in thatsubsiding center section 13 is comprised of relatively small spaced apart interval sections each defining a curved surface surroundingcenter section 11.Handle 30 may be formed in various shapes other than a semi-circle in that a user may hold onto it with convenience. - As shown with respect to
FIG. 9 , in an exemplary embodiment, airtightsalad bowl container 50 can be arranged in set where variousairtight containers 30 become gradually smaller in size and are mutually accommodated by one another. In a particular embodiment, the lid associated withcontainer 50 includes ahandle 30 placed onlid 1 of the biggest airtight container and not placed in lid (1′) of remaining airtight containers. - Regarding the
lid 1 as illustrated inFIG. 6 , external force is spread fromcenter section 11 torim reinforcing section 15 of thecontainer blocking section 10 and converted to be slanted toward the external and upward direction A oflid 1 at subsidingcenter section 13 Force is also distributed in this manner when downward pressure is applied to the top oflid 1 as a result of an involuntary fall, for example. Accordingly, these examples relate to application of external force under the condition where upward opening of the main body ofcontainer 40 is blocked, namely the state where lockingwings 21 are fastened to thewing connection part 31 of the main body ofcontainer 40. As a result, internal force B is generated atrim reinforcing section 15 Thusrim reinforcing section 15 and lockingwing 21 are more closely adhered to main body ofcontainer 40. Therefore, locking maintenance of lockingwing 20 becomes more solidified and sealing force oflid 1 is further improved as well. - A lid of an airtight salad bowl container according to the present disclosure improves sealing force when downward pressure is applied by involuntary fall of the airtight container or external force by effectively distributing the external force and converting the direction of the external force in the container blocking section. This is accomplished by having an overall upward protrusion toward the center in sectional projection. The container blocking section is separated as a center section, a subsiding center section and a rim reinforcing section all surrounded by a rim. As a result, a lid of an airtight salad ball container is provided that does not open involuntarily from an involuntary fall or downward pressure is applied.
- Although the present invention was described with reference to circular airtight salad bowl containers, it can be applied to the lids of various airtight containers and shapes of lids may vary as well corresponding to the shape of upward opening of the airtight containers according to the technical idea of the invention.
- While the present invention is described herein with reference to illustrated embodiments, it should be understood that the invention is not limited hereto. Those having ordinary skill in the art and access to the teachings herein will recognize additional modifications and embodiments within the scope thereof. Accordingly, such modifications and/or embodiments are considered to be included within the scope of the present invention.
