Description

Sealed container with opening / closing control for cover

[0001] The present invention relates to a sealed container having an opening / closing control unit for a cover, and more particularly, to a sealed container having an opening / closing control unit for a cover whose structure has been improved to enable the cover to be opened / closed more stably and effectively by taking into account even the case where a vacuum is created inside the container body during the process of opening / closing the cover from the container body.

[0002] An airtight container includes a container body for storing or containing food and a cover for opening and closing and sealing the upper part of the container body, and is often used to store coffee beans, ingredients, vegetables, meat, etc.

[0003] These sealed containers generally have two structures that separate the container body and the cover.

[0004] One structure includes a wing-shaped tab extending from the cover and not connected to the container body, allowing the cover to be separated from the container body. In this structure, a user can separate the cover from the container body by holding the container body with one hand and pulling the tab with the other. This pulling of the tab is necessary to overcome the frictional force of the seal that maintains an airtight seal between the container body and the cover, thereby separating the cover from the container body.

[0005] Another structure, a conventional one, features a clamp extending from the cover and connected to the container body, allowing the clamp to be opened and closed. While this structure maintains a firm connection between the container body and the cover, the clamp protrudes and is more complex than the tab structure.

[0006] Here, the structures of conventional sealed containers have a structure that protrudes from the container body or cover, so there is a risk of opening due to external force such as contact with other objects when placed in a bag or refrigerator, and there is a problem in that the appearance is not attractive.

[0007] To solve these problems, a structure has recently been proposed that allows the cover to be opened and closed on the plate surface of the cover without the tab structure or clamp structure described above.

[0008] However, recently proposed technologies also have the problem of having a protruding shape in order to heat the food inside the container using microwaves, etc., and there is a concern that the container may not close firmly in some cases during the closing process.

[0022] Additionally, it is preferable that external air enters and exits the container body in the area where the air passage member is coupled to the air hole.

[0023] In addition, it is preferable that the air hole is combined with the plug and the air passage member moves downwards from the air hole area, thereby blocking the entry and exit of external air into the container body.

[0024] In addition, it is preferable that when the user presses the opening / closing control unit in the closed position so that it is at the same height as the plate surface of the cover, the opening / closing control unit closes the air hole, thereby restricting the entry / exit of external air into the container body.

[0025] In addition, it is preferable to include a stopper extending downward to the plate surface of the control body of the opening / closing control unit so that the height of the opening / closing control unit in the closed position is the same as the height of the plate surface of the cover.

[0041] And, in order to facilitate explanation or understanding, the sealed container (1000) according to the present invention is defined as the 'Y' axis in the up-down direction with reference to Fig. 1, the left-right direction in the longitudinal direction is defined as the 'X' axis, and the direction perpendicular to the XY plane, which is the front-back direction, is defined as the 'Z' axis.

[0042] A sealed container (1000) according to one embodiment of the present invention, as illustrated in FIGS. 1 to 3, comprises a container body (1100) having an opening (1110) formed therein, a space formed inside the opening (1110), an upper end (1130) on the upper side, and a container wall (1150) extending downward from the upper end (1130); A cover (1300) detachably coupled to the opening (1110) so as to be movable between a closed position (see FIGS. 4a and 4g) where the opening (1110) is closed and sealed by a sealing portion (1200) described below and an air hole (1333) is blocked, and an open position (see FIGS. 4c and 4d) where the opening (1110) is opened and the cover (1300) is separated from the container body (1100); a sealing portion (1200) coupled to the cover (1300) so as to maintain airtightness between the container body (1100) and the cover (1300); It is preferable to include an opening / closing control unit (1700) that is provided so as to be able to open / close the cover (1300) with respect to the container body (1100) by being connected to a recessed portion (1330) that is recessed into the plate surface of the cover (1300) so as to be rotatable with respect to the cover (1300) on one side and contacting the upper portion (1130) on the other side; and a vacuum valve unit (1700) that is connected to the opening / closing control unit (1700) so as to be able to lift / lower to open / close an air hole (1333) formed through the recessed portion (1330) so as to allow external air to enter / exit the container body (1100).

[0043] The container body (1100) has an opening (1110) formed at the top to accommodate food, etc. in a typical sealed container (1000), and has a container wall (1150) extending upward from the bottom of the opening (1110), and an upper portion (1130) that contacts the edge of a cover (1300) on the upper side of the container wall (1150).

[0044] In this embodiment, the shape of the container body (1100) is depicted as a square, but it can be transformed into various shapes, including a circle.

[0045] The material of the container body (1100) may include a glass material that can be heated by microwaves and is impact-resistant, but may also be a ceramic material or a corrosion-resistant plastic material.

[0046] The cover (1300) has a cover body (1310) that has a plate shape and a border (not shown) located on the upper side of the upper part (1130) so that the opening (1110) can be opened and closed, and forms an exterior having a plate shape in the center, a cover skirt (not shown) that extends downward near the border area of ​​the cover body (1310), a sealing joining member (1350) to which a sealing part (1200) is joined to the outer border portion of the cover skirt, and a recessed part (1330) to which an opening / closing control part (1700) is joined and supported.

[0047] The material of the cover (1300) or the opening / closing control part (1700) includes plastic and can be transformed into various known materials.

[0048] The lower part of the edge of the cover body (1310) which is shaped like a plate and has an edge extending upwards has a container contact member (1370) formed corresponding to the shape of the upper part (1130) that comes into contact with the upper part (1130).

[0049] A pair of opposing rotating protrusions (1331) protrude from the side wall of the recessed portion (1330), and an air hole (1333) is formed through the bottom to allow air to enter and exit the container body (1100), and the air hole (1333) is opened and closed by a vacuum valve portion (1700).

[0050] The vacuum valve part (1700) includes a valve body (1510), a catch member (1337), a plug coupling member (1520), and a plug (1530).

[0051] The valve body (1510) is provided in a roughly rectangular shape and is coupled to a valve receiving member (1720). The valve body (1510) has a large upper side and a small lower side, and a plug coupling member (1520) having a large stepped structure at the lower end to which a plug (1530) is coupled so that the plug (1530) can be maintained in position. The plug coupling member (1520) is coupled to a coupling member fastening hole (1531) formed in a recessed manner corresponding to the shape of the plug coupling member (1520) at the upper side of the plug body (1533).

[0052] The plug (1530) is coupled to the plug coupling member (1520) and has a plug body (1533) whose upper side has an outer diameter larger than that of the valve penetration hole (1730). The plug body (1533) has an upper side having a larger outer diameter and a lower side having an outer diameter smaller than the larger outer diameter, so that the upper and lower sides have a step. In addition, a plurality of air passage members (1535) are formed on the outer surface at a set height and depth at the lower end.

[0053] And it is preferable that the air hole (1333) be round or chamfered on the entrance side to facilitate the plug (1530) attachment.

[0054] By this structure, when the user opens or closes the cover (1300) by separating or combining it from the main body (1100), air can enter and exit the inside of the main body (1100), thereby allowing the cover (1300) to be opened and closed stably and with little force.

[0055] And, the vacuum valve unit (1700) is coupled to the opening / closing control unit (1700), so that the vacuum valve unit (1700) can freely rise and fall with respect to the opening / closing control unit (1700).

[0056] Limiting the upper plate surface of the vacuum valve portion (1700) from descending further (coming down) than the upper plate surface of the opening / closing control portion (1700) can be achieved by a valve body (1510) coupled to a valve receiving member (1720) that is sunken into the control body (1710) and has a jaw formed therein.

[0057] Limiting the vacuum valve unit (1700) from rising higher than a set height (rising upward, see 'H3' in FIG. 4F) from the opening / closing control unit (1700) can be achieved by a plug body (1533) having an outer diameter larger than the valve penetration hole (1730).

[0058] And the height or stroke at which the upper plate surface of the vacuum valve part (1700) protrudes from the upper plate surface of the opening / closing control part (1700) is the height difference between the lower part of the lowest part of the valve body (1510) and the upper plate surface of the plug body (1533) (see 'GAP' in FIG. 3, see 'H3' in FIG. 4f).

[0059] The sealing member (1200) is connected to the sealing joint member (1350) of the cover (1300) to maintain an airtight seal between the cover (1300) and the container body (1100), thereby preventing food, etc. contained in the container body (1100) from leaking out. The sealing member (1200) pressurizes the container wall (1150) to generate a frictional force that prevents the cover (1300) from being separated from the container body (1100) when the cover (1300) is separated from the container body (1100).

[0060] One of the functions that enables the user to overcome this frictional force in the process of opening the cover (1300) from the closed position to the open position is the opening / closing control unit (1700) according to the present invention.

[0061] A user can pull up the opening / closing control unit (1700) by pressing the grip member (1760) area of ​​the opening / closing control unit (1700) with his / her hand. When the user presses, the rotating projection (1331) of the recessed portion (1330) and the rotating projection (1331) are engaged with the projection engaging hole (1743) of the opening / closing control unit (1700), and the upper contact member (1750) in contact with the upper portion (1130) overcomes the frictional force of the sealing portion (1200) through a seesaw motion to push up the cover (1300), so that the cover (1300) can be separated from the container body (1100).

[0062] It is preferable that the opening / closing control unit (1700) include a control body (1710) that forms the exterior and supports the configuration, a grip member (1760) formed so that a user can hold it, an upper contact member (1750) provided on the lower side of the edge of the cover body (1310) with a shape corresponding to the shape of the upper part (1130) so as to come into contact with the upper part (1130), a valve receiving member (1720), a valve penetration hole (1730), a protrusion coupling rib (1740) in which a protrusion coupling hole (1743) is formed, and a stopper (1780).

[0063] The control body (1710) is depicted as a square shape, but can be transformed into various shapes such as a circle or an oval.

[0064] The valve receiving member (1720) is a region that receives the upper side of the valve body (1510) of the vacuum valve part (1700) and is recessed from the plate surface of the valve body (1510). In addition, a valve penetration hole (1730) is formed through the bottom of the valve receiving member (1720) so that a plug coupling member (1520) to which a plug (1530) is coupled passes through.

[0065] The protrusion coupling rib (1740) is formed in a plate shape extending from the lower plate surface of the adjusting body (1710) so that a protrusion coupling hole (1743) can be formed in which a pair of rotating protrusions (1331) protrudingly formed on both side wall plates of the recessed portion (1330) are coupled.

[0066] Here, the rotary projection (1331) is provided as an example in which the rotary projection (1331) is protruded and the rotary projection engaging hole (1743) is formed to engage with the rotary projection (1331). However, the rotary projection may be sunken (not shown) and the rotary projection engaging hole may be protruded (not shown) to engage with the sunken rotary projection.

[0067] The biting member (1513) has a function of maintaining the state of engagement with the engaging member (1337) of the side wall of the valve receiving member (1720) so that the valve body (1510) is coupled to the valve receiving member (1720) and the height of the upper plate surface of the control body (1710) and the upper plate surface of the valve body (1510) are maintained the same.

[0068] The stopper (1780) is provided in the shape of a plate extending from the lower plate surface of the control body (1710) close to the grip member (1760) so that the upper plate surface of the cover (1300) and the upper plate surface of the control body (1700) can maintain the same height during the process of the opening / closing control unit (1700) being received in the recessed portion (1330) and the rotational movement of the control unit (1700). In addition, the width of the stopper (1780) is formed narrower than the width of the control body so that it functions as a passage so that external or internal air can enter and exit toward the air hole (1333) (see the partially enlarged 'air path' in FIG. 3).

[0069] And it is preferable that the outer diameter of the lower side of the plug body (1533) coupled with the plug (1530) (see 'D2' of FIG. 4f) is larger than the inner diameter of the air hole (1333) (see 'D1' of FIG. 4f). And it is preferable that the plug (1530) includes an elastically deformable and hygienic material including silicone or the like.

[0070] By this structure, when the user presses the plate surface on the cover (1300) side in the process of combining the cover (1300) with the container body (1100), the cover (1300) is combined with the container body (1100), and even if the upper part (1130), the upper part contact member (1750) and the container contact member (1370) come into surface contact, the plug body (1533) is not combined with the air hole (1333) because the outer diameter of the plug body (1533) is larger than the outer diameter of the air hole (1333). That is, the vacuum valve part (1700) can be protruded with respect to the opening / closing control part (1700) or the plug body (1533) is partially coupled to the air hole (1333) (in this case, air can enter and exit through the air passage member (1535)) (see FIG. 4f) so that the container body (1100) and the cover (1300) can be completely sealed or closed by the sealing part (1200) (outside air can enter and exit the container body (1100) through the recessed part (1330).

[0071] The operation process of a sealed container (1000) having such a configuration is specifically described below with reference to FIGS. 4a to 4g.

[0072] First, the state shown in Fig. 4a is a closed position, and the air hole (1333) is closed, and the internal space between the container body (1100) and the cover (1300) is blocked from the outside air by the sealing part (1200) and the vacuum valve part (1700) to maintain airtightness.

[0073] As shown in Fig. 4b, the user presses upward on the grip member (1760) with one hand.

[0074] By the pressure of the user, the opening / closing control unit (1700) rotates counterclockwise and rises by the engagement of the rotary projection (1331) and the projection engaging hole (1743) with the area where the upper portion (1130) and the upper portion contact member (1750) are in contact (see 'H' of FIGS. 4b to 4f) as a support point (see 'θ1' of FIG. 4b).

[0075] On the other hand, the cover (1300) gradually rises clockwise by the engagement of the rotating protrusion (1331) and the protrusion engaging hole (1743) with the area where the upper right side (1130) of the container body (1100) and the container contact member (1370) are in contact with each other as a support point (see 'θ2' in Fig. 4b).

[0076] In this process, the plug (1530) blocking the air hole (1333) also rises, allowing outside air to flow in through the air passage member (1535). Therefore, even if the cover (1300) is separated upwards from the container body (1100), the vacuum inside the container body (1100) is released, so that no vacuum is formed inside the sealed container (1000), allowing the cover (1300) to be separated from the container body (1100) with little force.

[0077] Of course, in this process, the sealing part (1200) is in close contact with the inside of the container wall (1150) of the container body (1100), thereby maintaining airtightness between the inside of the container body (1100) and the cover (1300).

[0078] As shown in Fig. 4c, as the user's pressure gradually increases, the rise of the opening / closing control unit (1700) relative to the container body (1100) (see 'θ1-1' in Fig. 4c) and the rise of the cover (1300) (see 'θ2-2' in Fig. 4c) increase according to the counterclockwise rotation of the opening / closing control unit (1700) and the clockwise rotation of the cover (1300), so that the sealing unit (1200) on the opening / closing control unit (1700) side is separated from the container wall (1150) and exposed to the outside.

[0079] By exposing this sealing portion (1200), the cover (1300) can be simply and easily separated from the container body (1100) without much resistance, so that the cover (1300) is separated from the container body (1100) and is in the open position.

[0080] Of course, the user can quickly reach the open position of Fig. 4c from the closed position of Fig. 4a by using a large amount of force instantaneously.

[0081] To summarize what was explained above, the user holds the grip member (1760) in the closed position and presses the opening / closing control member (1700) upward, causing the cover (1300) to move to the open position.

[0082] In this process, the sealing portion (1200) that adheres to the container wall (1150) of the cover (1300) and the container body (1100) to maintain airtightness gradually moves upward toward the upper portion (1130), and the vacuum valve portion (1700) that was blocking the air hole (1333) also moves upward along the opening / closing control portion (1700), opening the air hole (1333).

[0083] The opening / closing control unit (1700) rotates counterclockwise using the area where the upper part (1130) and the protrusion coupling hole (1743) come into contact (see 'H' in FIG. 4b and FIG. 4c) as a support point, and the cover (1300) rotates counterclockwise using the area where the upper part (1130) on the right side and the container contact member (1370) come into contact as a support point.

[0084] And the area where the rotary protrusion (1331) and the protrusion coupling hole (1743) are combined or interlocked moves upward.

[0085] When the sealing portion (1200) on the left side comes off the upper portion (1130), the user can simply and conveniently separate the cover (1300) from the container body (1100) with one hand.

[0086] Meanwhile, the process of the user operating the cover (1300) from the open position to the closed position is described in detail with reference to FIGS. 4d to 4g as follows.

[0087] First, as shown in FIG. 4d, the user positions the cover (1300) in the opening (1110) of the container body (1100) and slightly presses the cover (1300) plate surface.

[0088] As illustrated in FIG. 4e, when a user presses the cover (1300) plate downward toward the container body (1100), the sealing portion (1200) moves downward while contacting the inside of the container wall (1150). At the same time, the opening / closing control portion (1700) and the cover (1300) are positioned in a position similar to FIG. 4b due to contact between the upper portion (1130), the upper portion contact member (1750), and the container contact member (1370).

[0089] That is, the contact between the upper part (1130) and the upper part contact member (1750) of the opening / closing control part (1700) (see 'H' in FIG. 4e) and the rotation protrusion (1331) is engaged or engaged with the protrusion engaging hole (1743), so that the opening / closing control part (1700) rotates clockwise and the height protruding from the cover (1300) gradually decreases, and the vacuum valve part (1700) also gradually moves toward the air hole (1333).

[0090] As the user increasingly presses the cover (1300) plate surface, as shown in FIG. 4f, the container contact member (1370), which is the lower edge of the cover (1300), contacts the upper part (1130) of the container body (1100), and the upper part contact member (1750) of the opening / closing control unit (1700) also contacts the upper part (1130), so that the plate surface of the cover (1300) and the plate surface of the opening / closing control unit (1700) become the same height.

[0091] On the other hand, since the lower outer diameter (see 'D2' of FIG. 4f) of the plug (1530) of the vacuum valve part (1700) facing the air hole (1333) is larger than the inner diameter (see 'D1' of FIG. 4f) of the air hole (1333), the plug (1530) pressurizing the air hole (1333) cannot be combined with the air hole (1333). That is, among the downward force trying to be combined with the air hole (1333) and the force of the air hole (1333) pushing the plug (1530) upward, the force of the air hole (1333) pushing the plug (1530) upward is stronger, so the plug (1530) cannot be combined with the air hole (1333), and the opening / closing control part (1700) protrudes upward from the plate surface of the control body (1710) (see 'H3' of FIG. 4f).

[0092] Even though the engaging member (1337) of the cover (1300) and the biting member (1513) of the valve body (1510) are engaged, the force of engagement is overcome, and the vacuum valve part (1700) comes into contact with the air hole (1333) with respect to the control body (1710), and the plug (1530) protrudes upward due to the pushing force.

[0093] That is, it is preferable that the force of engagement between the engaging member (1337) and the biting member (1513) is less than the force exerted by the air hole (1333) of the small inner diameter of the plug (1530) when the large outer diameter of the plug (1530) comes into contact with the air hole (1333) and pushes the plug (1530) upward. That is, the size including the height and depth of the protrusion shape of the engaging member (1337) and the recessed shape that engages with the protrusion shape is appropriately selected.

[0094] And, by the protrusion of this vacuum valve part (1700), air can enter and exit the inside of the container body (1100) through the air passage member (1535), and by the flow of this air, contact between the upper part (1130) of the container body (1100), the container contact member (1370), and the upper part contact member (1750) is completely made, so that the sealing part (1200) can be maintained in a stable and effective manner.

[0095] Next, as illustrated in FIG. 4g, when the user confirms that the upper part (1130) of the container body (1100) and the container contact member (1370) and the upper part contact member (1750) are in complete contact and presses the protruding vacuum valve part (1700), the vacuum valve part (1700) is received in the valve receiving member (1720), so that the heights of the upper plate surface of the vacuum valve part (1700) and the upper plate surface of the opening / closing control part (1700) become the same. The plug (1530) is completely coupled to the air hole (1333), so that the air passage member (1535) is positioned below the air hole (1333).

[0096] That is, the sealing portion (1200) maintains an airtight seal between the inside of the container wall (1150) and the cover (1300), and the air hole (1333) is blocked, so that air does not flow into or out of the container body (1100) and the cover (1300).

[0097] By this structure, the cover (1300) is closed more effectively in the process of moving from the open position to the closed position.

[0098] While various embodiments of the present invention have been illustrated and described herein, those skilled in the art will appreciate that modifications to the embodiments described herein can be made without departing from the principles or spirit of the invention. The scope of the invention is defined by the appended claims and their equivalents.
