Description

There is an application for the application of Article 30, Paragraph 2 of the Patent Law ▲1 ▼ Date of publication November 18, 2nd year of Reiwa ▲2 ▼ Place of sale 2-13-16 Higashi Motomachi, Kokubunji City, Tokyo

TECHNICAL FIELD The present invention relates to an attachment or the like used for the lid of a cooking vessel in order to turn the metal lid member of the cooking vessel upside down and use it as a frying pan with a handle.

Conventionally, cooking containers with lids exist. In Japan, portable cooking containers especially used for camping and mountain climbing are called 'kochel' or 'cooker' and are devised to be compact and not bulky. As such a portable cooking container with a lid, there is a cooking container shaped like a lunch box with a lid on the main body. Non-Patent Document 1 is an example of a website disclosing such a cooking container. The lid of the container described in Non-Patent Document 1 is turned upside down to form a plate-like shape with a wall that rises around the periphery. It merely serves as a lid or a container such as a plate on which rice, side dishes, or the like is placed.

However, in camping and mountain climbing, it is better to carry as little luggage as possible, so multifunctional cooking containers are desired in order to reduce luggage. Therefore, by giving the lid of the bento box-shaped cooking container of Non-Patent Document 1 a function as a frying pan, it is assumed that the functionality is enhanced so that a separate frying pan does not have to be prepared. However, in reality, the lid of the cooking container as in Non-Patent Document 1 does not have a handle. It could not be used as a cooking utensil.
In view of these problems, the present invention provides an attachment for a lid of a cooking vessel that can be used as a frying pan with a handle by inverting the lid of the cooking vessel without a handle.

A first means for solving the above problems is an attachment for use as a frying pan with a handle by turning a metal lid member of a cooking container upside down, wherein the lid member stands up by being turned upside down. an engaging portion that engages with the upper end of the peripheral wall and the inner surface of the peripheral wall continuing from the upper end of the peripheral wall; a support portion that supports the top plate portion of the lid member arranged at the bottom position by inverting from the lower surface; and a connection portion for connecting the support portion, and a handle is attached to the connection portion.
By engaging the engaging portion with the upper end of the peripheral wall and the inner surface of the peripheral wall continuing from the upper end of the peripheral wall, and supporting the top plate portion of the lid member from the lower surface with the support portion, the upside-down lid member is supported in a cantilever manner by the attachment. It will be done.
As a result, the attachment can be attached to the peripheral wall position of the lid member with the lid member of the cooking vessel turned upside down, and the lid member can be separated by grasping the handle attached to the connecting portion of the attachment by the user. Since the lid member can be supported like a supporting beam, it becomes possible to use the lid member as a frying pan.
The engagement portion, the support portion, and the connection portion of the attachment may be configured integrally, or may be configured by combining a plurality of members. The material of the attachment should be heat-resistant and light. Light metals such as aluminum alloys and titanium alloys are preferred. Plastic with high heat resistance may be used. As the plastic, for example, fluorine resin or melamine resin is preferable. It may also be made of ceramic.
It is necessary that the handle to be used is attached to the connecting portion and fixed so as not to swing up and down with the connecting portion as a starting point at least when lifted. When attaching the handle to the connecting portion, the handle may or may not be detachable from the connecting portion.

As a second means, the connecting portion is formed with an abutting portion that abuts against the outer surface of the peripheral wall of the lid member during use.
Theoretically, the lid member can be supported in a cantilever manner by the weight of the lid member only with the engaging portion and the support portion. It is necessary to reduce rattling between the lid member and the attachment. Therefore, by forming the abutting portion that contacts the outer surface of the peripheral wall of the cover member in the connecting portion, the engaging portion is in contact with the inner surface of the peripheral wall, and the contact portion of the connecting portion is in contact with the outer surface of the peripheral wall, whereby the peripheral wall is formed. The lid member supported by the attachment is stabilized by being sandwiched from the inside and outside.
Further, as a third means, the contact portion is formed in a shape along the surface shape of the outer surface of the peripheral wall of the lid member.
When the abutting portion has a shape along the surface shape of the outer surface of the peripheral wall of the lid member, the abutting portion contacts the peripheral wall of the lid member not at a point but at a surface, so that the lid member is more supported by the attachment. stability will be increased.

Further, as a fourth means, the handle is detachable from the connecting portion.
Thus, when the handle is separate from the attachment, it is not bulky to store, and the luggage that the user needs to carry, including the cooking container, can be made more compact.
As a fifth means, the handle used for supporting the main body of the cooking vessel is removed and attached to the connecting portion for use.
This eliminates the need to prepare a unique handle for the attachment, thus reducing the amount of luggage that the user must carry.

In the above invention, the attachment can be attached to the peripheral wall position of the lid member in a state in which the lid member of the cooking vessel is turned upside down, and the lid member can be lifted by the user gripping the handle attached to the connecting portion of the attachment. Since it can be supported like a cantilever beam, the lid member can be used as a frying pan.

Specific embodiments of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 to 4, the attachment 1 of this embodiment is a solid block made of aluminum alloy and made by extrusion molding. In the following description, the left direction of the attachment 1 shown in FIG. 2 is defined as the front.
Since the attachment 1 is an extrusion-molded product, the cross section in the horizontal width direction basically appears to have the same shape. The dimension of the attachment 1 in the lateral width direction is 40 mm in this embodiment. The attachment 1 is provided with an engaging portion 2 arranged upwardly in use, a connecting portion 3 extending downward from the engaging portion 2, and a support portion 4 projecting forward from a lower position of the connecting portion 3. there is On the rear surface (rear surface) of the attachment 1, a handle contact surface 5 is formed in which boundaries of the engaging portion 2, the connecting portion 3, and the supporting portion 4 are smoothly continuous and integrated. The handle contact surface 5 is formed as a single plane as a whole, and is arranged substantially vertically when the attachment 1 is in use.
The engaging portion 2 is formed so as to bend forward from the upper end of the connecting portion 3 in a side view and protrude in a "<" shape, and in the left-right width direction, it has a groove-like appearance with a length of 40 mm and an upside down direction. present. Inside the engaging portion 2, a vertical surface 2a is arranged vertically when the attachment 1 is used, a ceiling surface 2b is arranged downward from the upper end of the vertical surface 2a, and an obliquely forward downward direction is arranged from the lower end of the ceiling surface 2b. Three faces of the guide face 2c arranged towards each other are formed.
The connecting portion 3 is formed in a plate body whose front and back sides are parallel planes, that is, in a flat plate shape. The boundary between the engaging portion 2 and the connecting portion 3 is not clear, and although they are adjacent to each other, they gradually and smoothly transition from one area to the other. In this embodiment, the connecting portion 3 is configured with a thickness of 4 mm as an example.
As shown in FIG. 3A, the distance P1 between the vertical surface 2a of the engaging portion 2 and the front surface 3a of the connecting portion 3 matches the thickness of the lid wall 17 of the lid 14, which will be described later.

The protruding shape of the support portion 4 is sandwiched between a shelf surface 6 extending forward from below the front surface 3a of the connecting portion 3 and an oblique surface 7 extending obliquely forward and upward from the lower end of the handle contact surface 5. consists of The shelf surface 6 is formed in a shape obtained by cutting the inner peripheral surface of a cylinder that is straight in the left-right width direction and concave upward in a direction orthogonal to the width direction. The oblique surface 7 is configured as a plane. A lid abutting portion 8 extending in the width direction is formed at the position where the shelf surface 6 and the inclined surface 7 intersect. The lid abutting portion 8 rises shallowly from the shelf surface 6 and presents a ridged appearance. A flat lid contact surface 8 a is formed on the upper surface of the lid contact portion 8 . In the present embodiment, the lid contact surface 8a has a rectangular shape with a front-rear width of 4 mm and a left-right width of 40 mm.
As shown in FIGS. 1, 2, etc., a lightening portion 9 cut in a substantially arch shape is formed in the center of the support portion 4 in the lateral width direction in order to reduce weight and prevent deformation. A handle bearing portion 10 is formed in a transition region from the engaging portion 2 to the connecting portion 3 of the handle contact surface 5 . The handle bearing portion 10 has a ridged outer shape protruding rearward from the handle contact surface 5, and a tunnel-shaped bearing hole 11 having a circular cross section is formed in the lateral width direction. Since the attachment 1 is an extruded product, the handle bearing portion 10 has the same cross-sectional shape. The handle bearing portion 10 of the present embodiment is formed into a completed shape by cutting both side portions formed during molding so as to be flush with the handle contact surface 5 .

Next, the lid 14 of the cooking vessel 13 to which the attachment 1 is attached will be described.
As shown in FIG. 4, the lid 14 is part of a portable aluminum alloy cooking vessel 13 . The cooking container 13 as a whole has a cuboid shape with rounded and chamfered corners, and has a so-called “lunch box” appearance. The basic structure of the cooking container 13 is a lid 14 and a container body 15 on which the lid 14 is covered.
The lid 14 is composed of a substantially rectangular top plate 16 with rounded corners and a shallow lid wall 17 surrounding the entire periphery of the top plate 16 . The lid 14 is used, for example, to cover the container body 15 from above when cooking rice, or is used as a plate for receiving cooked rice and side dishes. The container body 15 is composed of a bottom plate 18 having a shape similar to that of the lid 14 and a body wall 19 rising from the bottom plate 18 and surrounding the entire periphery of the bottom plate 18 and relatively higher than the lid wall 17 . The container main body 15 is used, for example, as a deep plate for putting water and rice in when cooking rice or boiling water.
A handle 21 is attached to the side surface of the container body 15 via a bearing metal fitting 20 . As shown in FIGS. 4 and 5, the handle 21 is constructed by bending one wire, and has a substantially trapezoidal handle portion 21a and an internal angle of about 80 degrees with respect to the handle portion 21a. A pair of bent portions 21b rising from the tip of the handle portion 21a and a pair of rotating shaft portions 21c bent at right angles so as to face each other at the tips of the bent portions 21b. The outer periphery of the handle portion 21a is covered with a cover 23 made of synthetic rubber. The outer space between the pair of bent portions 21b is a little less than 40 mm. By inserting a pair of rotating shaft portions 21c into the bearing holes 22 of the bearing metal fittings 20 of the container body 15, the handle 21 can swing up and down about these shafts. When the handle 21 of the container body 15 is used as the handle 21, as shown by the solid line in FIG. is held by a cantilever, and when the handle 21 is not used, that is, when it is stored, the handle 21 can be turned upside down as shown by the virtual line in FIG. 21a is placed on the upper surface of the lid 14 in a fallen state.

Next, a method of attaching the attachment 1 for using the lid 14 of the cooking container 13 as a frying pan will be described.
The handle 21 of the cooking container 13 can remove the rotating shaft portion 21c from the bearing fitting 20 by moving the two wire portions of the handle portion 21a in a direction away from each other. Therefore, in this embodiment, the removed handle 21 is used as the handle of the attachment 1 as it is.
As shown in FIGS. 2 and 3, opposite to the process of removing the handle 21 from the container body 15, the two wire portions of the handle portion 21a are moved in a direction away from each other, and the pair of rotating shaft portions are moved. 21c is attached from both sides of the bearing hole 11 of the handle bearing portion 10 so that the bent portion 21b hangs down. The bent portion 21b just fits within the width of the attachment 1 when attached. Further, although the length of the bent portion 21b is configured to be about 28 mm, since the distance from the center of the bearing hole 11 to the lower end of the handle abutment surface 5 is about 30 mm in the attachment 1 of the embodiment, the bent portion 21b can also be gripped. It fits just within the region of the handle contact surface 5 without protruding downward from the hand contact surface 5.例文帳に追加In other words, the handle 21 is attached so that the region defined by the pair of rotation shafts 21c and the pair of bent portions 21b of the handle 21 fits within the handle contact surface 5 without protruding. In the state where the handle 21 is attached to the attachment 1, if the handle contact surface 5 is arranged vertically, the handle 21 has the bent portion 21b as a base, and the handle portion 21a is substantially horizontally rearward (actually, in the horizontal direction). 10 degrees upward) (state shown in FIG. 3(b)).
With the handle 21 attached to the attachment 1 in this way, the user holds the handle portion 21a of the handle 21, and as shown in FIG. The engaging portion 2 is engaged so as to be hooked.

More precisely, run:
The height of the lid wall 17 of the lid 14 is longer (higher) than the interval P2 between the lower end of the open end of the engaging portion 2 and the lid contact surface 8a shown in FIG. Even if it approaches the wall 17, the engaging part 2 will interfere with the lid wall 17. - 特許庁Therefore, in order to prevent such interference, the attachment 1 is first approached obliquely from above the upper edge 17a of the lid wall 17, and engaged along the guide surface 2c as shown in FIG. 6(a). The upper edge 17 a is guided in the groove of the joining portion 2 and the upper edge 17 a is brought into contact with the ceiling surface 2 b in the engaging portion 2 .
6A from this state, the handle 21 is rotated in the direction of the arrow in FIG. The top plate 16 is brought into contact with the back surface of the bread (which will be the bottom of the bread). With the upper surface of the lid contact surface 8a in close contact with the top plate 16, the inner surface of the lid wall 17 and the vertical surface 2a of the engaging portion 2 come into contact with each other as shown in FIG. It faces the front surface 3a of the connecting part 3. As shown in FIG. That is, the lid wall 17 is sandwiched between the vertical surface 2a of the engaging portion 2 and the front surface 3a of the connecting portion 3 from the front and rear.
In this state, the attachment 1 is attached to the lid 14 correctly. When the user grips the handle portion 21a of the handle 21, a load is applied in the direction of the arrow in FIG. Can be operated as a frying pan.

By configuring as described above, the attachment 1 of the embodiment has the following effects.
(1) The lid 14 without a handle can be used as a frying pan by attaching a handle 21 to the lid 14 via the attachment 1, and the function of the cooking container can be improved.
(2) Since the handle 21 is originally attached to the cooking container 13, it is possible to give the cooking container 13 the function of using the lid 14 as a frying pan as long as the cooking container 13 and the attachment are provided. No need to prepare a handle.
(3) The attachment 1 supports the upper edge 17a of the lid wall 17 of the lid 14 with the engaging portion 2 on the upper side, and only supports the top plate 16 from the lower side with the lid contact portion 8 at the tip of the support portion 4. The lid 14 can be held in a cantilever manner by the weight of the lid 14 on the outside. This system eliminates the need for fixing parts such as a chuck device and screws for attaching the attachment 1 to the lid 14, and the weight of the attachment 1 is reduced.
In addition, attachment and detachment of the attachment 1 is easy because it is a work of simply hooking it on the lid wall 17 .
(4) The attachment 1 supports the lid 14 with the engagement portion 2 and the support portion 4, and the lid wall 17 is sandwiched from the front and rear by the vertical surface 2a of the engagement portion 2 and the front surface 3a of the connecting portion 3 at the intermediate position. The attachment 1 is stably fixed at this position because the lid wall 17 is sandwiched between the surfaces as well as simply supported.
(5) The handle 21 swings up and down with the rotation shaft 21c of the handle 21 as a base. Because of the contact, the handle portion 21a of the handle 21 is extended and fixed in a substantially horizontal direction that is easy for the user to hold.
