The storage container for storing the storage (for example, food) and the container lid that opens and closes the opening of the storage container are kept tightly coupled to each other so that the storage inside the storage container can be maintained. Try to store or maintain freshness for a long time.

  Recently, various techniques have been introduced and applied to improve the airtightness between the container lid and the storage container when they are joined.

  For example, as in LOCK & LOCK (trade name), a technique for storing a stored item is applied by tightly coupling a container lid and a storage container to maintain an airtight state.

  In the case of such LOCK & LOCK and similar products, a locking means for coupling the storage container and the container lid is prepared.

  The lock means is configured to be foldable on the side surface of the container lid and to be coupled / released with a coupling protrusion formed on the outer peripheral surface of the storage container.

  However, the storage container and the container lid that are coupled / released by the locking means may be opened / closed by the operation of the storage container and the locking means (e.g. The container lid must be opened and closed with one hand, or after one side of the container lid coupled with the storage container is coupled / released, the same operation must be repeated multiple times at each other coupling site. ) Is very troublesome and inconvenient to use.

  In addition, the locking means that is formed integrally with the container lid is broken by a folding operation that is repeated multiple times, or the storage container and the container lid are loosened when used for a long period of time, and the airtight state becomes the initial airtight state. There was a problem that it was significantly reduced compared to the state.

  In addition, the container lid made of a flexible rubber or synthetic resin material has a problem that it is generally thin and easily deforms its original shape and is distorted well.

  In addition, the conventional storage container lid has a problem that heat sterilization for disinfection is impossible because it is weak against heat during heat disinfection (for example, deformation of the shape occurs when heat of 50 ° C. or more is applied). It was.

  The storage container 200 is provided with an opening 210 for storing or taking out stored items on one side.

  As shown in FIG. 15, the side wall 214 of the storage container 200 is provided with an airtight protrusion accommodating portion 212 for coupling the container lid 100.

  FIG. 2 is a cross-sectional view illustrating a container lid 100 provided with a hard material cover 110 according to an embodiment of the present invention.

  Referring to the drawing, a container lid 100 is formed on one side of a storage container 200 to open and close an opening 210 through which stored items are put in and out.

  The container lid 100 may include a cover part 110 that covers an upper part of the opening part 210, and a flexible frame 140 that opens at the top / bottom part of the cover part 110 to open and close the opening part 210.

  Here, the cover portion 110 can be formed in various shapes. For example, when the storage container 200 is formed in a square box shape or a cylindrical shape, the cover portion 110 has a quadrangular or circular shape corresponding to the opening 210 of the storage container 200. It is formed.

  The cover part 110 can be formed of various materials. For example, the cover part 110 is entirely formed of a hard material separately from the flexible frame 140 or is made of the same flexible material as the flexible frame (for example, silicone material). It can also be formed.

  When the cover part 110 is formed of a hard material, the cover part 110 can be formed with a thickness of 1 mm to 3 mm, and preferably has a grip feeling suitable for maintaining the original shape or when the user takes it by hand. It can be formed to have a thickness of about 2 mm.

  As shown in FIG. 2, the cover part 110 projects toward the storage container 200, and the cover part 110 is seated at the normal position of the opening 210 when the container lid 100 is coupled to the storage container 200. A seating protrusion 111 is provided to guide the guide.

  The seating protrusion 111 may be spaced apart from the flexible frame 140 by more than the thickness of the side wall of the storage container 200 (see 't1' in FIG. 2) so that the side wall 214 of the storage container 200 can be easily coupled. preferable.

  The seating protrusion 111 can be formed in various shapes, for example, a quadrangular protrusion or a cylindrical protrusion.

  The seating protrusions 111 are interconnected and formed in a ring shape, or are formed in a plurality so as to be divided and arranged.

  The seating protrusion 111 may be formed integrally with the cover portion 110 made of a hard material, or may be formed separately and attached to the cover portion 110.

  As shown in FIG. 5, the seating protrusion 111 is formed with one or more airtight protrusions 142 a that protrude toward the side wall 214 of the storage container 200 and come into contact with the side wall 214 to increase the sealing performance. The

  The airtight protrusion 142a can be formed in various shapes. For example, the airtight protrusion 142b can be formed as a pleated airtight protrusion 142b as shown in FIG. 6, and the pleated airtight protrusion 142b and the protrusion-shaped airtight protrusion 142c as shown in FIG. The protrusion-shaped airtight protrusion 142d may be formed separately as shown in FIG.

  When the airtight protrusion 142b is formed in a pleat shape, the elasticity is improved while the pleat portion extends in contact with the outer edge of the side wall 214 of the storage container 200, and the sealing force can be increased.

  When the airtight protrusion 142c is formed in a protrusion shape, it can be formed in a shape corresponding to the airtight protrusion accommodating portion 212 formed on the side wall of the storage container 200 as shown in FIG.

  In this case, in the process in which the storage container 200 and the container lid 100 are coupled, the airtight protrusion 142c is sandwiched between the airtight protrusion accommodating portions 212 to prevent the storage container 200 from being detached from the container lid 110 when the opening 210 is sealed. Have a role to play.

  The airtight protrusions 142a, 142b, 142c, 142d are in airtight contact with the inner and outer edges of the side wall 214 of the storage container 200, and when the storage container 200 is tilted, vibrated or externally impacted, the storage container 200 The stored product can be prevented from flowing into a gap that can be generated between the container lids 100 to be joined.

  When the cover part 110 is made of a flexible material, the original shape of the cover part 110 can be maintained when the flexible frame 140 is opened by providing the cover part 110 with the reinforcing part 120 as shown in FIG. .

  When the cover part 110 is made of a flexible material, the cover part 110 can be formed to a thickness of 1 mm to 3 mm, preferably to prevent tearing or to have a grip feeling suitable for the user to take it by hand. It is formed to about 2 mm.

  The reinforcing part 120 can also perform a function like the above-described seating protrusion 111, and the reinforcing part 120 is formed from the flexible frame 140 to a thickness greater than the side wall thickness of the storage container 200 (see “t1” in FIG. 3). Then, it is formed so as to protrude toward the storage container 200 beyond a predetermined length.

  When the flexible frame 140 is opened to the upper and lower parts, the reinforcing part 120 blocks the opening of the cover part 110 from the position where the reinforcing ring 121 is provided, and deforms the cover part 110 (for example, the cover part is concave). ).

  The reinforcing portion 120 is formed with one or more airtight protrusions 142a and 142f that protrude and contact the side wall 214 of the storage container 200 to increase the sealing performance.

  The airtight protrusions 142a and 142f are formed in various shapes such as a protrusion shape or a pleat shape.

  The airtight protrusions 142a and 142f have the same role as the airtight protrusions 142b, 142c, 142d, and 142e described above.

The reinforcing part 120 is formed on a reinforcing ring 121 embedded adjacent to the end of the cover part 110 and a protective plate 122 that wraps and protects the reinforcing ring 121.

  Here, the reinforcing ring 121 can be formed in various shapes. For example, as shown in FIG. 6, the cross section can be formed in a tubular shape having a space in the center, and in a rod shape as shown in FIGS. It can also be formed. In this case, the cross section of the reinforcing ring 121 can be formed without being limited to a square shape or a circular shape.

  The reinforcing ring 121 can be formed of various materials, for example, a metal or a synthetic resin material having high hardness.

  Of course, the reinforcing ring 121 can be formed of the same material as the cover 110 and can be made of different materials.

  The flexible frame 140 is formed to extend in the thickness direction of the cover part 110. The flexible frame 140 elastically extends and includes an elastic material, and opens to the upper part of the cover part 110 when the opening part 210 is opened, and covers the cover part 110 when sealed. It is opened at the lower part of the opening 210 so as to wrap around the outer edge of the opening 210 and close it.

  The flexible frame 140 can be formed in various shapes. For example, as shown in FIG. 2, the one side that contacts the outer edge of the side wall 214 is formed in a flat shape (for example, a single character), 3 is formed in the same area (see “t3” in FIG. 3) with a predetermined area or thickened from the cover part 110 side as shown in FIG. Formed).

  The flexible frame 140 may have various thicknesses, and is preferably formed to have a thickness equal to or greater than the thickness of the membrane hinge 130 connected to the cover part 110 (see 't2' in FIG. 3).

  For example, the thickness of the central portion of the flexible frame 140 can be formed to be 3.5 mm to 5 mm so that the bonding force can be optimized when contacting the outer edge of the storage container 200. It is preferable to form in about 2 mm.

  In this case, when the flexible frame 140 is opened up and down, the folds can be concentrated on the membrane hinge 130, and the sealing force in a state where the storage container 200 and the container lid 100 are joined and sealed is increased. .

  The flexible frame 140 is configured to shrink toward the inside depending on the characteristics of the elastic material, so that a diameter smaller than the outer diameter of the cover part 110 can be maintained.

  The flexible frame 140 can be used by being opened to any one side without any upper / lower section around the cover portion 110.

  As shown in FIG. 9, the flexible frame 140 is elastically stretched in the opposite direction of the storage container 200 when the connection is released from the storage container 200 in order to put or remove the stored material in the storage container 200. To keep open.

  As shown in FIG. 10, the flexible frame 140 is elastically stretched when it is combined with the storage container 200 in a state in which the storage container 200 is filled with a stored product or a storage product is taken out from the storage container 200. However, it opens to the storage container 200 side so that the outer edge of the opening 210 is wrapped and closed.

  The flexible frame 140 is formed with one or more airtight protrusions 142a, 142b, 142c, 142d, 142e that are in contact with the outer edge of the side wall 214 of the storage container 200 to increase the sealing performance.

  The airtight protrusions 142a, 142b, 142c, 142d, and 142e have a role like the airtight protrusion described above.

  The membrane hinge 130 is formed so as to be integrated by interconnecting the cover part 110 and the flexible frame 140.

  The membrane hinge 130 is formed on the peripheral surface of the cover part 110, and the outer surface of the membrane hinge 130 is formed on the inclined surface 131.

  The inclined surface 131 of the membrane hinge 130 can be formed to have a downward inclination angle of 40 ° to 50 °. When the angle of the inclined surface 131 is smaller than 40 °, the thickness of the membrane hinge 130 is thin and the service life is shortened. When it is prevented from being shortened or larger than 50 °, the thickness of the membrane hinge 130 is increased, thereby preventing an excessive force from being applied when the flexible frame 140 is opened on the upper part of the cover part 110. Thus, it is preferably formed at about 45 °.

  The thickness of the membrane hinge 130 can be formed to 0.7 mm to 1.5 mm, and is most preferably formed to a thickness of about 1.1 mm so that the upper and lower portions of the flexible frame 140 can be easily opened. .

  Hereinafter, a process of combining the container lid 100 according to the present invention with the storage container 200 will be described.
