Definitions

  • This invention relates to container technology, in particular to a sealed container with a detachable lid for storing food and liquid.
  • Containers are not only used to meet the requirement of storing liquid or solid, but also to provide secure closure to prevent spoilage of food and to transport or carry easily and conveniently.
  • Cida patent CN102229371A discloses a food storage container, comprising a base and a lid; said lid is made of plastic, the circumference of said lid having a convex border toward the base; the opening edge of said base features an outward flange mated to the lid border; the sidewall of said lid also has a plurality of integral forming gripping jaws, said gripping jaws engage to the base flange to couple the lid and the base; said lid and said base are sealed with the help of a sealing ring; a securing ring with the shape of the cross section is movably coupled to the exterior of the lid, said securing ring being made of elastic deformative plastic; the length of the sidewall of said securing ring matches to the exterior of the lid and the length of securing claws coupled thereto, a plurality of transversely protruding hooks located near to the bottom of the interior of the sidewall, when the lid and the base tightly binding together, said hooks coupled to the lower
  • U.S. Pat. No. 6,196,404 discloses a triple seal container. Said contain forms three seals upon mating of the base and the lid. Said container is capable of sealing securely but is not easy and convenient to open.
  • the present invention provides a container that can be sealed securely and also easily and readily assembled and disassembled.
  • a container with seal structure comprising a base and a lid, wherein said lid having
  • the exterior region of said lid sealing edge and the exterior region of said base sealing edge are concentric arcs
  • the interior region of said lid sealing edge and the interior region of said base sealing edge are straight lines extended from the end of the arcs with different tilted angles.
  • said lid top features an annular slot and said base bottom features an annular ridge, said annular slot and said annular ridge featuring coincided projective position and being molded to be mateable, said annular ridge fitting into said annular slot when the base is placed on the lid top.
  • said lid sidewall extending substantially vertically or at an outward angle downward from said lid top, facilitating stacking of a plurality of lids.
  • said base sidewall extending substantially vertically or at outwardly extending angle downward from said base bottom, facilitating stacking of a plurality of bases.
  • said base and said lid are substantially rectangular or square configuration
  • said base and said lid are substantially in the shape of a round cylinder.
  • the angle between said lid rim and said base rim is 5-10°.
  • Said base and said lid are made of plastic or rubber material.
  • the present invention improves the seal structure between the base and the lid, featuring attached sealing region between the edges of the lid and the base, which is gradually parting from the sealed region to the inner section to form a gap.
  • Such structure allows better sealing effect with regard to plastic molding products, ensuring outermost sealing as well as easy disassembly.
  • FIG. 1 is a schematic view of a cuboid container
  • FIG. 2 is a schematic view of a cylinder container
  • FIG. 3 is a schematic view of the seal when the lid is put on a base
  • FIG. 4 is an enlarged view of section A of FIG. 3 ;
  • FIG. 5 is a schematic view of a base is put on the lid.
  • FIGS. 1 and 2 show the integral structure diagram of the present invention.
  • Said container may be in a shape of rectangle as in FIG. 1 or a circle as in FIG. 2 .
  • Said container comprises a lid 100 and a base 200 .
  • Lid 100 features lid top 110 , the center of said lid top being a substantially planar surface and the peripheral of the planar surface featuring an annular slot 130 .
  • Lid sidewall 120 is formed by extending downward from the periphery of lid top 110
  • lid rim 103 is formed by extending horizontally outward from the lid sidewall 120 .
  • Lid sealing edge is extending outward from the lid rim 103 , said sealing edge comprising the interior region 102 closed to the lid rim and the exterior region 101 far from the lid rim.
  • Barb 104 is hanging over the lid sealing edge at the end of the exterior region.
  • Base 200 features bottom 210 , the center of the bottom being a substantially planar surface and the peripheral of the planar surface featuring an annular ridge 230 .
  • Base sidewall 220 is extending upward from the periphery of the base, and base rim 203 is extending horizontally outward form the base sidewall 220 .
  • Base sealing edge is extending outward from base rim 203 , said base sealing edge comprising an interior region 202 closed to the base rim and an exterior region 201 far from the base rim.
  • the lid sealing edge and the base sealing edge are molded to be mateable, and upon mating, the exterior region 101 of said lid sealing edge and the exterior region of 201 of said base sealing edge are attached to form a sealed region, the interior region 102 of said lid sealing edge and the interior region 202 gradually parting from the point of attachment, forming a gap between said lid rim 103 and said base rim 203 .
  • the exterior regions of both lid sealing edge and base sealing edge are concentric arcs
  • the interior regions of said lid sealing edge and base sealing edge are straight lines with different tilted angles extending from the end of the arcs
  • the angle a between the lid rim and the base rim is approximately 10°.
  • the annular slot 130 on the lid top and the annular ridge 230 on the base have coincided projective position and are molded into matched shapes, said annular ridge fitting into the annular slot when the base is placed on top of the lid top, as illustrated in FIG. 5 .
  • Such structure allows the lid being placed underneath the base stably when disassembled, reducing storage space.
  • said lid sidewall is extending substantially vertically or at an outward angle downward from said lid top, facilitating stacking of a plurality of lids.
  • Said base sidewall is extending substantially vertically or at outwardly extending angle downward from said base bottom, facilitating stacking of a plurality of bases.
  • Said base and said lid are made of plastic or rubber material, allowing the base and the lid to be plastic.
