Definitions

  • the present invention relates to a sealed container lid having a vacuum valve.
  • a packing is engaged at a container lid, and the packing keeps a close contact with a rim of the container body.
  • a sealed container may be provided with a locking wing so as to obtain a sealed engagement force of a lid.
  • a sealing force is disadvantageously weak.
  • a sealing force of the lid is good, but opening and closing the locking wing causes many inconveniences when in use.
  • a vacuum valve 22 is engaged at a center of the container lid 21 .
  • a silicon packing 23 is engaged near an outer side of the container body.
  • the silicon packing 23 is closely contacted with an inner wall surface 25 of the container body 24 .
  • the air of the container body 24 is discharged to the outside through the vacuum valve 22 by pressing the container lid 21 .
  • a valve seat 26 is closed by softly pressing the vacuum valve 22 .
  • a negative force is formed in the container body 24 for thereby preventing the container lid 21 from being opened and obtaining a strong sealing force, so that the foods stored in the interior of the container is safely stored.
  • the container lid 21 is made of a plastic material based on an injection method, whereas the packing is made of a silicon rubber material. Namely, the materials are different from each other.
  • a vertically opened circular groove 27 is formed at the container lid 21 .
  • a ring-shaped fixing member 29 having a plurality of insertion protrusions 28 formed at regular intervals is provided so as to obtain a certain fixing force.
  • the insertion protrusions 28 pass through the packing 23 .
  • the fixing member 29 is inserted into the circular groove 27 for thereby finishing an engagement of the packing 23 .
  • a certain member fixing member
  • a certain member is additionally needed so as to engage the packing 23 . Since an assembling process is further needed, the mold and manufacture costs increase, and the productivity decreases.
  • a circular groove 30 provided for fixing the packing 23 may be formed and opened in a horizontal direction.
  • a silicon packing 23 having a relatively large elastic force is extended so that the diameter increases, and is inserted into the circular groove 30 , the packing 23 is not easily escaped from the circular groove 30 by a force as allowing the diameter to decrease for thereby obtaining a relatively strong engaging force.
  • a process for engaging or disengaging a lid to a container body may be performed based one-touch method.
  • a sealed container lid of a vacuum valve operation type which includes a vacuum valve as operating with a certain pressure by communicating an interior of a container body and the outside or disconnecting the same, and a silicon packing for sealing the interior of the container body in close contact with an inner wall surface of the container body
  • a sealed contained lid of a vacuum valve operation type which comprises a body which is injection-molded and has a circular groove formed in a horizontally and outwardly opened shape for an engagement of the silicon packing; and a downwardly bent peripheral part which is formed at an outer peripheral part of the body based on a double injection method while surrounding the same.
  • FIG. 1 is a view illustrating a sealed container lid of a vacuum valve operation type according to the present invention
  • FIG. 2 is a view illustrating a dual injection structure of a sealed container lid of a vacuum valve operation type according to an embodiment of the present invention
  • FIG. 3 is a view of a conventional art
  • FIG. 4 is a view illustrating a container lid which may be manufactured based on an injection method.
  • FIG. 1 is a view illustrating a sealed container lid of a vacuum valve operation type according to the present invention
  • FIG. 2 is a view illustrating a dual injection structure of a sealed container lid of a vacuum valve operation type according to an embodiment of the present invention.
  • reference numeral 1 represents a container lid
  • 2 represents a container body in which the container lid 1 is opened and closed.
  • a vacuum valve 4 for an opening and closing operation of a lid is engaged at a body 3 of the container lid 2 .
  • a valve seat 5 of the vacuum valve 4 is lifted off the valve seat 6 , the interior 8 of the container body 2 is opened through a valve hole 7 with respect to the outside.
  • the valve hole 7 is closed, and the interior 8 of the container body 2 is disconnected with the outside.
  • a circular groove 9 is formed at the body 3 in a horizontal direction and is open in the outward direction.
  • a silicon packing 10 having a smaller diameter and a high elastic force is formed at the circular groove 9 . When it is engaged, it is needed to enlarge the diameter by pulling the same.
  • a downwardly bent peripheral part 12 is engaged at an outer peripheral part 11 of the body 3 while surrounding a peripheral part 2 a of the body 2 .
  • the body 3 is first manufactured based on the injection method and is provided with an opened circular groove 9 as being horizontally formed in an outward direction.
  • the downwardly bent peripheral part 12 is formed at the body 3 based on a double injection method.
  • the silicon packing 10 is inserted into the circular groove 9 for thereby finishing the manufacture of the lid 1 .
  • the downwardly bent peripheral part 12 may be separately manufactured and assembled at the body 3 as compared to the earlier described method in which the downwardly bent peripheral part 12 is formed on the body 3 based on the double injection method.
  • the silicon packing 10 is closely contacted with the inner wall surface 15 of the container body 2 .
  • the body 3 of the container lid 1 is softly pressed, the air of the interior of the container body 2 is discharged to the outside through the valve hole 7 .
  • the valve seat 5 is closely contacted with the valve seat 6 by softly pressing the vacuum valve 4 , the interior 8 of the container body 2 is disconnected from the outside.
  • the pressed body 3 returns to its original position by the elastic force, since a certain vacuum pressure is formed in the interior, it is possible to prevent the lid 1 from being opened based on a generation of negative pressure in the container. So, it is possible to obtain a strong sealing force.
  • the vacuum valve 4 When it is needed to separate the container lid 1 from the container body 2 , the vacuum valve 4 is lifted upward, so that a valve assembly 5 is separated from the valve seat 6 .
  • the vacuum of the interior 8 of the container body 2 disappears, so that the inner and outer spaces communicate.
  • the container lid 1 can be easily opened.
  • the silicon packing 10 is not easily escaped even if a certain fixing member is not used in the present invention. Namely, the silicon packing 10 is elastically extended and inserted into the circular groove 9 , so that it is not easily escaped due to a strong inward contraction force.
  • a downwardly bent peripheral part as surrounding an outer peripheral part of the container body may be formed on a lid body based on a double injection method or may be separately manufactured and assembled.
  • a circular groove for an engagement of a silicon packing is formed at the lid body in a horizontally and outwardly opened shape, not in a vertical direction. So, it is possible to obtain a stable engagement without using an additional fixing member of the silicon packing.
  • the assembling process decreases, and the productivity is enhanced.
  • the manufacture cost advantageously decreases.
