  As described above, the lid body of the container with lid employs the packing body with the packing attached to the packing base to the plug part (the other member) by means such as valve member interposition mounting, screwing mounting, and peripheral wall fitting mounting. Has been. Therefore, there is a problem of an increase in manufacturing cost due to a complicated structure and a need for manufacturing accuracy. Further, there is a problem that the operation of attaching and detaching the member is troublesome when cleaning the packing body. In addition, when the screwing of the packing body is adopted, there is a structural problem that must be attached with the lid mounting screw and the reverse screw in consideration of the container body attaching / detaching operation (screwing rotation operation) of the lid body. Since the packing body and the lid are integrated, the friction between the inner surface of the container body and the packing becomes a rotational resistance during the rotation operation when the lid is mounted, thereby reducing the operability when the lid is mounted. ing.

  Therefore, the present invention proposes a novel container with a lid that has a simple packing body attachment / detachment structure and facilitates attachment / detachment.

  A container with a lid according to the present invention includes: a container body; a lid body that includes a plug portion that is inserted into the upper opening of the container body; and a packing body that is detachably provided on the plug portion. A container with a lid, wherein the stopper lower end portion of the lid body is formed to have an appropriate small diameter, and a locking collar portion is provided so that the small diameter portion becomes a concave peripheral surface, A packing body that is in contact with the surface and exhibits a water sealing function is a flat container shape that can be crowned from below on the locking collar, and has an appropriate elasticity that protrudes on the locking collar on the peripheral wall. A stop protrusion is provided.

  Thus, when the packing body is pushed upward from below the lid portion of the lid body, the peripheral wall portion reaches a position above the locking collar portion, and at the same time, the locking protrusion protruding in the center direction from the peripheral wall portion. Then, the packing body is mounted on the lower portion of the lid portion of the lid. Therefore, the packing body is attached and detached by bending due to the elasticity of the locking projection of the packing.

  When the lid is screwed and attached to the container body in the attached state, the packing body is in a freely rotating state with the lid body, so when the packing comes into contact with the inner surface of the opening of the container body, friction with the packing causes The packing body is brought into a non-rotating state, and the packing is pressed against the inner surface of the opening of the container body by further screwing rotation of the lid body, thereby realizing water sealing of the container body. Therefore, when the cover body is mounted on the container body by the rotation operation, the packing that contacts the inner surface of the container body does not become a resistance.

  The configuration of the present invention is as described above, and the packing body can be easily attached to and detached from the plug portion of the lid body, which is convenient for cleaning and the like, and the lid body adopts screwing mounting. In this case, the packing does not serve as a resistance when the lid is mounted, and the lid is smoothly mounted.

  Next, an embodiment of the present invention will be described. The container with a lid shown in the embodiment includes a container body 1, a lid body 2, and a packing body 3.

The container body 1 is a heat insulating container having a vacuum double structure composed of an outer container 11 and an inner container 12 made of stainless steel. A receiving convex portion 14 is formed at a lower portion of the upper opening 13 and a screw is formed on the upper inner peripheral surface thereof. A strip 15 is formed. Further, the outer peripheral surface of the upper opening 13 is formed on the outer peripheral surface 16 having a small diameter through a step.

  The screw 15 may be formed on the outer peripheral surface 16 of the mouth, and in that case, a mounting screw 23 is formed on the inner surface of the outer peripheral covering portion 22 of the lid, which will be described later.

  The lid 2 includes a plug portion 21 inserted into the upper opening portion 13 and an outer peripheral covering portion 22 that covers the outer peripheral surface 16 of the mouth portion. The plug portion 21 has a mounting screw 23 corresponding to the screw portion 15. Further, the lower end side of the plug portion 21 is formed to have an appropriate small diameter, the lower end surface reaching the small diameter portion is a pressing surface portion 24, the small diameter portion is a concave peripheral surface 25, and a locking rod is formed on the lower end portion. The part 26 is provided around. Further, a recess 28 is formed in the center of the lower end surface 27 of the plug portion 21.

  The packing body 3 includes a packing plate 31 and a ring packing 32. The packing plate 31 has a flat container shape formed by a bottom surface portion 311 and a peripheral wall portion 312. A laterally long through hole 313 is appropriately formed in the peripheral wall portion 312. The inner peripheral wall 314 that fits into the concave portion 28 is provided at the center of the bottom surface portion 311, and the inner peripheral wall 314 has a small size. A pressure reducing / opening valve mechanism comprising an on-off valve 316 formed of a flexible material that closes the through-hole 315 and the small through-hole 315 is provided.

  The ring packing 32 includes a ring main body 321 having an inverted U-shaped cross section made of a material having appropriate flexibility, and a locking protrusion 322 protruding from the ring main body 321 toward the center. The locking projection 322 has a shape corresponding to the through hole 313 and has a tip corresponding to the outer diameter of the concave peripheral surface 25. The ring packing 32 is configured such that the ring main body 321 is fitted and attached to the outer periphery of the peripheral wall portion 312 of the packing plate 31, and at the same time, the locking protrusion 322 is inserted into the through hole 313 and protruded from the peripheral wall portion 312 toward the center.
