Description

Technology Field

[0001] The present invention relates to a food storage container, and more specifically, to a sealed food storage container configured to safely store food for a long time by sealing a container containing contents such as food through the connection of a lid, while simultaneously releasing the sealed pressure formed inside the container when the lid is separated from the container, allowing the lid of the sealed container to open more easily, and making it suitable for stacking and storing multiple containers. Background Technology

[0002] Generally, airtight food storage containers allow various foods to be placed in the container's receiving portion and sealed by closing the lid, thereby ensuring that the food can be stored and eaten without spoiling even when placed in the container for a long time.

[0003] Currently, airtight containers made of glass, stainless steel, plastic, or silicone are sealed by covering the container holding food with a lid that has a packing formed on the top of the container to ensure a tight seal, thereby creating a sealing pressure inside the container. At this time, to facilitate the separation of the lid from the container, a separate stopper is pivotally connected to the upper surface of the lid to release the sealed sealing pressure with a single touch.

[0004] However, when separating or attaching such conventional airtight container lids, the stopper formed on the lid is opened to release the sealing pressure generated by the sealing inside the container. Typically, one hand is held in the container and the other hand is held in the lid to separate or attach it. Since most of these methods require gripping the entire surface of the lid with the hand spread wide to open or close it, there is considerable inconvenience when gripping the lid. Furthermore, when the lid is large and the entire surface cannot be gripped, the lid is usually separated from the container by gripping the upper and lower surfaces in a clamp-like manner. This presents a problem in that the lid does not open easily due to the characteristics of the airtight container. Additionally, the sealing pressure release stopper provided separately on the upper surface of the lid protrudes, which is aesthetically unpleasing and inconvenient when stacking multiple containers for storage. Prior art literature

[0005] Republic of Korea Published Utility Model Publication No. 20-2011-0007691 (August 3, 2011) The problem to be solved

[0006] The present invention aims to solve the aforementioned conventional problems, and its purpose is to provide a food storage (sealed) container configured to be advantageous for stacking multiple containers for storage, while simultaneously releasing the sealed pressure formed inside the container and allowing the lid to be opened more easily when the lid is separated from the container by sealing the container containing contents such as food through the coupling of a lid, and also resolving structural disadvantages caused by conventional sealing pressure release plugs (e.g., structural disadvantages due to the protruding structure of the sealing pressure release plug structure or misalignment with the lid). means of solving the problem

[0007] To achieve the aforementioned objective, a food storage container according to one aspect of the present invention may comprise: a container for storing contents; and a lid formed to seal the container. A first recessed portion having a shape and size corresponding to the lower portion of the container is formed on the upper surface of the lid, and a second recessed portion having one side open is formed on the bottom surface of the first recessed portion, and a ventilation hole penetrating the bottom surface of the second recessed portion is formed. An open lever having a shape corresponding to the second recessed portion is seated on the second recessed portion, wherein the open lever is formed to block the ventilation hole of the second recessed portion, and one end in the direction of the long axis is spaced apart from the corresponding end of the second recessed portion, and the other end passes through the opening of the second recessed portion and is positioned below one end of the lid. A coupling member for axially coupling the open lever in the direction of the short axis is formed on the second recessed portion, so that both ends in the direction of the long axis of the open lever can move in a seesaw motion by means of the coupling member.

[0008] According to another aspect of the present invention, the open lever may have a projection formed on its upper surface that extends in the direction of the shortest length and protrudes upward, and one side of the projection may be formed as a curved surface that corresponds to and matches the curved surface extending from the bottom surface of the first recess to the side.

[0009] According to another aspect of the present invention, the coupling member may include a pair of shaft protrusions (or shaft grooves) formed on both sides in the short axis direction of the second recess, and a pair of shaft grooves (or shaft protrusions) formed on both sides in the short axis direction of the open lever so that the pair of shaft protrusions (or shaft grooves) can be fitted and rotated. Effects of the invention

[0010] As described above, according to various aspects of the present invention, when a user separates the lid from the container, the sealed pressure formed inside the container is released with only a simple one-touch motion, and the lid of the sealed container is opened easily. In particular, it eliminates structural disadvantages caused by conventional sealing pressure release plugs (e.g., structural disadvantages caused by the sealing pressure release plug structure protruding from the lid or misalignment with the lid), and creates the effect of improving safety during use, storage, and transportation by enabling the safe stacking and support of multiple containers.

In assigning reference numerals to the components of each drawing, identical components are assigned the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, when describing embodiments of the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the present invention, such detailed description is omitted.

[0014] As illustrated in FIGS. 1 to 4, a food storage container according to an embodiment of the present invention may include a container (1), a lid (3), an open lever (5), and a packing (7).

[0015] Referring to the drawings, a food storage container according to an embodiment of the present invention is basically configured to include a container (1) for storing contents and a lid (3) for sealing the container (1), and may include an open lever (5) that allows the lid (3) to be easily opened from the container (1) in a one-touch manner, and may also include a gasket (7) interposed between the container (1) and the lid (3) to seal the space between them (1, 3).

[0016] The lid (3) may include a first indentation (31) and a second indentation (33) formed on the upper surface.

[0017] The first recess (31) is formed with a shape and size corresponding to the lower surface of the recessed container (1), and the lower surface of the container (1) is recessed tightly into the first recess (31) formed on the upper surface of the lid (3) to be supported, thereby making it advantageous for stacking and storing the container, and accordingly, the convenience and safety of use can be improved during use, storage, transportation, etc. of the container.

[0018] The second recess (33) is formed to mount the open lever (5) so as not to protrude from the upper surface of the lid (3), and is formed by being recessed downward from the bottom surface of the first recess (31), and can be formed with a size and shape corresponding to the open lever (5).

[0019] The second recess (33) may include an opening (33a) that is closed around the circumference while penetrating one side in the direction of the long axis, and a ventilation hole (35) penetrating the bottom surface of the second recess (33) is formed.

[0020] The open lever (5) is formed in a shape corresponding to the second recess (33) and is seated on the second recess (33). The first end (5a) in the direction of the long axis is spaced apart from the corresponding first end of the second recess (33) by a certain distance, and the other end (5b) in the direction of the long axis is extended in the direction of length so as to penetrate one side of the second recess (33) through the opening (33a) formed in the second recess (33) and be aligned and positioned immediately below the end including one end of the lid (3), so that both sides of the other end (5b) are positioned and contact between the upper edge surface of the container (1) and the lower edge surface of the lid (3). That is, the open lever (5) is formed to be seated in the second recess (33), with the leading edge in the long axis direction spaced apart from the leading edge in the long axis direction of the second recess (33), and the short axis length formed to fit exactly the short axis length of the second recess (33).

[0021] On the upper surface of the open lever (5), a matching protrusion (51) is formed to match the upper surface of the open lever (5) with the shape and form of the upper surface of the lid (3). The protrusion (51) protrudes upward and is formed to extend by the length of the short axis in the direction of the short axis of the open lever (5). One side of the protrusion (51) is formed as a curved surface (511) with a shape that corresponds to and matches the curved surface (311) extending from the bottom surface of the first recess (31) of the lid (3) to the side. Therefore, when the open lever (5) is seated in the second recess (33) of the lid (3), the upper surface of the open lever (5) is aligned with the bottom surface and side surface of the second recess (33) to form a continuous surface, thereby resolving structural disadvantages caused by conventional sealing pressure release plugs (e.g., structural disadvantages caused by the sealing pressure release plug structure protruding from the lid or misalignment with the lid), and allowing multiple containers to be safely stacked and supported.

[0022] A plug (55) is formed protruding downward from the lower part of the open lever (5) to block the ventilation hole (35) formed on the bottom surface of the second recess (33).

[0023] The plug (55) is formed to fit into the ventilation hole (35), so that when the open lever (5) is seated and assembled in the second recess (33), the plug (55) can open and close the ventilation hole (35).

[0024] The plug (55) may be a plug for releasing the sealing pressure.

[0025] A connecting member is formed in the second recess (33) of the lid (3) to axially connect the open lever (5) in the short axis direction, and by the axial connection of the connecting member, both ends (5a, 5b) of the open lever (5) in the long axis direction can move in a seesaw motion.

[0026] For example, according to the present embodiment, the coupling member may include a (fitting) shaft protrusion (333) formed in the second recess (33) of the lid (3) and a (fitting) shaft groove (533) formed in the open lever (5).

[0027] The shaft protrusions (333) may be a pair of protrusions formed on both sides in the short-axis direction of the second recess (33), and the shaft grooves (533) may be a pair of grooves (533) formed on both sides in the short-axis direction of the open lever (5) so as to be fitted into the pair of shaft protrusions (333) and rotate.

[0028] Therefore, when the shaft groove (533) of the open lever (5) is inserted and coupled into the shaft protrusion (333) of the second recess (33) and the open lever (5) is seated in the second recess (33), the two ends (5a, 5b) of the open lever (5) in the direction of the long axis can move like a seesaw (or lever) with respect to the coupling axis (333+533) in the direction of the short axis.

[0029] The gasket (7) is a ring-shaped padding material that is interposed on the joint surface between the container (1) and the lid (3) to seal the gap between them, thereby preventing leakage.

[0030] FIG. 5 is an illustrative diagram for explaining the operating state of a food storage container according to an embodiment of the present invention, and the operation of the present invention will be explained with reference to the said diagram.

[0031] FIG. 5 is a cross-sectional example diagram showing the lid opening process of a food storage container according to an embodiment of the present invention, where FIG. 5 (a) shows the initial lid opening state, FIG. 5 (b) shows the intermediate lid opening state, and FIG. 5 (c) shows the final lid opening state.

[0032] Figures 4-5 show four states of a food storage container.

[0033] Figure 4 shows the lid (3) in a closed state, that is, a completely sealed state.

[0034] FIG. 5(a) shows the state of slightly lifting the open lever (5) to remove air from inside the container (1). With the lid (3) closed, cooking can be done in a microwave oven by opening only the open lever (5). When the open lever (5) is opened, it can function as a steam vent to release steam and pressure generated when heating food with electromagnetic waves. Therefore, since food can be cooked or heated with the lid (3) closed, the moisture of the food can be fully preserved.

[0035] FIG. 5(b) shows the lid (3) in an open state. Using the lever principle, the open lever (5) is lifted from one end (5a) of the open lever (5) with a finger or the like. The open lever (5) rotates about the lid (3) around the axis (333, 533), and the other end (5b) comes into contact with the top of the side wall of the container (1). At the same time, the other end (5b) comes into contact with the gasket (7) assembled on the bottom of the lid (3), thereby overcoming friction between the gasket (7) and the inner wall of the container (1) so that the lid (3) can be easily opened.

[0036] Figure 5 (c) shows the lid (3) in a fully open state, which is one step further than Figure 5 (b), so the explanation is omitted here.

[0037] According to the present invention, the open lever (5) is slightly lifted to release air, and then the lid (3) is lifted to open. With this simple one-step operation, the air can be released and the lid opened with one hand, making it convenient to use.

[0038] That is, according to the present invention, when separating the lid (3) from the container (1), the sealing pressure formed inside the container (1) is released by a simple one-touch operation of the open lever (5), and at the same time, the lid (3) of the sealed container is easily opened. In particular, as described above, the structural disadvantages caused by conventional sealing pressure release plugs (e.g., structural disadvantages caused by the sealing pressure release plug structure protruding from the lid or misalignment with the lid) are resolved by the alignment configuration of the lid (3) and the open lever (5), and multiple containers can be safely stacked and supported.

[0039] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by these embodiments.
