Description

  The present invention relates to a lid opening / closing structure of a pressure cooking container.

  As is well known, the pressure cooking container is a seal that is provided on the outer peripheral back surface of the lid body and is attached to the container body by overlapping the flange of the container body to ensure the sealing of the container body during cooking. Various types of lid opening / closing structures for hermetically mounting the lid are known. In the present invention, in particular, an arc-shaped locking piece that clamps the upper surface of the outer periphery of the lid body and the flange of the container body up and down is connected to an operation arm arranged in the radial direction of the upper surface of the cover body, and the operation arm is operated in the radial direction. The operation unit is provided, and the operation unit is moved to attach / detach (lock / unlock) the lid.

  As an operation part of the lid opening / closing mechanism of the pressure cooking container of the above-mentioned type, the operation unit is operated on the same plane (parallel plane) as the lid body surface (operation arm operation surface), and is operated in the vertical direction with respect to the lid body surface. A configuration is known.

  As the former configuration, an instrument provided such that the operation part moves in the radial direction (Patent Document 1: Japanese Patent Laid-Open No. 8-98766), an instrument having a structure for horizontally rotating the operation part (Patent Document 2: Japanese Patent Application Laid-Open No. H8-298706). 2007-190168) is known, and as the latter configuration, an instrument having an up-and-down rotating lever structure (Patent Document 3: Registered Utility Model No. 3125615), and an operation section having a push-down operation structure. An instrument (Patent Document 4: Registered Utility Model No. 3161839) is known.

JP-A-8-98766. Japanese Patent Application Laid-Open No. 2007-190168. Registered utility model No. 3125615. Registered utility model No. 3161839.

  As a matter of course, the operation of opening and closing the lid of the pressure cooking container is performed when the lid is mounted, and the lid is crowned and the lid is sealed (operation part operation). When the lid is removed, the lid is unsealed. (Operation of the operation unit) Two operations of lifting the lid are required.

  However, an instrument having a configuration in which the operation of the operation unit is operated on the same surface as the lid body has a problem in operability because the opening / closing operation and the crown / lifting operation are different directions.

  In addition, the instrument disclosed in the above-mentioned Patent Document 3 is different in the operation part (operation lever) and the holding part (pick body) of the lid, and the opening / closing operation is smooth in the instrument adopting the rotation operation lever. It is not performed in a series of operations, and a gear mechanism is adopted, so that it is easy to cause a failure.

  Further, as disclosed in Patent Document 4, it is possible to cover the lid with the lid held in a state where the lid is held and to seal the lid by pushing down the operation unit as it is. Is a circular pick, and it is difficult to hold the lid to perform a series of operations, and the structure is not simple because a link mechanism is adopted as an operation transmission mechanism.

Therefore, the present invention proposes a novel lid opening / closing structure for a pressure cooking container that has a simple structure and the handle of the lid functions as it is as an operation section.

  The lid opening / closing structure of the pressure cooking container according to the present invention is a pressure cooking container that ensures sealing by overlapping a packing provided on the outer peripheral back surface of the lid body on the flange of the container body when the lid is mounted. An arc-shaped locking piece that clamps the upper surface of the outer periphery of the container and the flange of the container body up and down is connected to an operating arm arranged in the radial direction on the upper surface of the lid body, and has an operating section that operates the operating arm in the radial direction. In the lid opening / closing structure of the pressure cooking container that moves and removes the lid, a cover body that is fixed to the lid body and covers the operating arm is provided, and the operating direction of the operating arm is set in the axial direction at the center of the cover body A rotary body is provided, and a fishing handle-like rotary handle that is connected to both ends of the shaft portion of the rotary body and exposed to the outside of the cover body is provided as an operating portion, and a connecting projection is provided on each central side of the operating arm. And projecting to the rotating body In addition to forming a guide groove that fits up and down, the guide protrusion is close to the connecting projection fitting position when the rotating handle is overlaid, and the locking piece is positioned below the flange of the container body, so that the rotating handle stands up. Corresponding to this transition, the connecting projection fitting position gradually moves away, and the locking piece is located outside the flange of the container body when the rotating handle is erected.

  Thus, when attaching the lid, if the lid is covered with the container while holding the upright pivoting handle, and the pivoting handle is laid down in this state, the guide groove is moved along with the pivoting of the pivoting body. At the same time, the engaging protrusion is moved in the center direction, and the upper surface of the outer periphery of the lid body and the flange of the container body are clamped up and down to obtain a locked state (sealed mounting state of the lid body).

  The removal of the lid is the reverse of the above operation, and when the tilted rotating handle is raised, the locking piece is detached from the outer periphery of the lid and becomes unlocked, and the lid is held while holding the rotating handle. It lifts the body.

  The configuration of the present invention is as described above, and there is no risk of failure with a simple structure. In particular, the attachment to and removal from the lid can be performed in a series while holding the rotating handle. The opening and closing operability is improved.

Explanatory drawing of the state at the time of the unlocking of the said action body, (a) is a rear view (b) is a rear perspective view. The perspective view of the cover body (perspective view from the safety valve side).

  Next, an embodiment of the present invention will be described. The pressure cooking container shown in the embodiment is basically composed of a container body A and a lid body B as before. The container body A has a top edge as a flange and a handle (both hands) a provided on the peripheral surface.

  The lid body B includes a lid body 1, a safety valve mechanism 2 attached to the lid body 1, and a lock mechanism (opening / closing structure) 3. The lid body 1 is basically the same as before, and the outer periphery is suspended. As shown in FIG. 1, a packing (not shown) is provided on the outer peripheral back surface, and a mounting hole 11 for the safety valve mechanism 2 is formed on the surface other than the location where the lock mechanism 3 is disposed. A predetermined safety valve device 2 is incorporated. Further, the lid main body 1 is provided with a mounting bolt hole 12 for a cover body 33 of the lock mechanism 3 to be described later.

  The safety valve mechanism 2 is a conventionally known one, and is provided with a pressure adjusting knob 21 for maintaining a predetermined pressure in the container body A during pressure cooking, an internal steam discharge port 22 and the like.

  The lock mechanism (opening / closing structure) 3 is exposed to the two locking pieces 31 a and 31 b and the operating arms 32 a and 32 b, the cover body 33, the rotating body 34 provided in the cover body 33, and the cover body 33. And a pressure action body 36 constituting a safety mechanism for opening and closing the lid.

  The locking pieces 31a and 31b are formed in a U-shaped cross-section and in a plane arc shape so that the upper surface of the outer peripheral edge of the lid body 1 and the flange of the container body 1 can be clamped up and down, and symmetrical to the outer edge of the lid body 1 Is to be placed.

  The operating arms 32a and 32b are connected to the respective locking pieces 31a and 31b and are arranged in the radial direction on the upper surface of the lid main body 1. The operating arms 32a and 32b are connected to the projections 321a and 321b at the tip portion (near the center of the lid main body 1). And a predetermined large diameter corresponding to the shape of the pressure operating body 36 at the place where the pressure operating body 36 is installed and the insertion long holes 322a and 322b of the fixing screws 331a and 331b of the cover body 33 to be described later. A dharma-type through-hole 323 having a small diameter portion continuous to the portion and the center side is provided.

  The cover body 33 has a shape that covers the entire operation arms 32a and 32b, and has fixed screws 331a and 331b protruding at predetermined positions on the back surface. The long holes 321a and 321b are passed through, and a nut is screwed and tightened on the back surface of the lid main body 1 to be fixed to the lid main body 1. A confirmation hole 332 is provided at a position corresponding to the Dalma-type through hole 322. .

  The rotating body 34 is provided with a shaft portion 341 having the operating directions of the operating arms 32a and 32b as axial directions at both ends, and is provided at the center position of the cover body 33. Guide grooves 342a and 342b into which the connecting protrusions 321a and 321b of 32a and 32b are respectively fitted are provided. The guide grooves 342a and 342b are formed in a square shape in which the distance between the left and right grooves changes while the rotating body 34 is rotated 90 degrees, and each of the couplings fitted when the distance between the grooves is closest. In the vicinity of the protrusions 321a and 321b, the locking pieces 31a and 31b are positioned below the flange of the container body A, and when the distance between the grooves is large and the connecting protrusions 321a and 321b are separated, the locking pieces 31a and 31b are It is formed so as to be located outside the outer periphery of the flange of the body A.

  The rotary handle 35 has a fishing hook shape that is exposed to the outside of the cover body 33, and is connected to the shaft portion 341 of the rotary body 34 so as to make upright and fall rotation. The connecting angle between the rotating body 34 and the rotating body 34 is such that the distance between the guide grooves 342a and 342b is close when the rotating handle 35 is lying down, and the distance between the grooves is increased corresponding to the transition of the rotating handle 35 to the standing state. It is what I did.

  The pressure operating body 36 has a shape in which the upper portion is a small diameter portion and the lower portion is a large diameter portion, and is provided at a predetermined position of the lid main body 1 so as to be movable up and down. When the value is equal to or less than the value, it is lowered and the small diameter portion is positioned at the height of the operating arm 32a, and the large diameter portion is positioned at the height of the operating arm 32a at high pressure.

  Thus, in order to perform pressure cooking with the appliance, the lid body B is attached to the container body A as in the past to keep the container body A in a sealed state. Is standing. When the rotating handle 35 stands up, the rotating angle of the rotating body 34 interlocked with the rotating handle 35 is determined, the distance between the guide grooves 342a and 342b is also increased, and the connecting protrusions 321a and 342a are connected to the guide grooves 342a and 342b. Since 321b is fitted, the locking pieces 31a and 31b are positioned outside the flange of the container body A (unlocked state). Accordingly, the lid body B is put on the container body A with the rotating handle 35 standing.

  After the cover body B is covered with the container body A, when the rotation handle 35 is laid down as it is, the rotation body 34 rotates, the distance between the guide grooves 342a and 342b becomes close, and the operation arms 32a and 32b The locking pieces 31a and 31b are moved to the center side along the radial direction using the fixing screws 331a and 331b as a guide, and the upper surface of the outer peripheral edge of the lid body 1 and the flange of the container body A are vertically clamped to lock the lid (lid Body hermetically attached state).

  In the locked state, the large-diameter portion of the Dalma-type through hole 323 serves as the position of the pressure operating body 36. Therefore, when the internal pressure (the internal pressure of the container body A) is high during cooking and after cooking, the pressure operating body 36 is It rises and advances into the large diameter portion of the Dharma type through hole 323. Therefore, in a state where the internal pressure is high, even if the rotary handle 35 is to be operated, the operation of the operating arm 32a is blocked by the pressure operating body 36 and cannot be shifted to the unlocked state.

  When the internal pressure decreases, the pressure operating body 36 descends and the operation arm 32a can move in the radial direction, and the locking pieces 31a and 31b move to the outer peripheral side by the rising operation of the rotary handle 35, and the lid B is removed. Is possible.

  As described above, according to the present invention, the lid B is locked / unlocked by standing upside down of the rotating handle (operating unit) 35. Therefore, the lid B is covered with the rotating handle 35 held. The lid B is attached and detached in a series of operations so that the lid B is removed when the lid B is locked down to lock the lid, or when it is gripped and lifted while causing the rotating handle 35 of the locked lid B. The operability is greatly improved.
