The present invention relates to a combination of a lid member, a handle, and an attachment for use as a frying pan with a handle by flipping the metal lid member of a cooking container upside down and attaching the handle to the lid member via an attachment. It is.

Cooking containers with lids have conventionally existed. In Japan, portable cooking containers used especially for camping and mountain climbing are called ``kochel'' or ``cooker,'' and are designed to be compact and not bulky. As one of these portable cooking containers with a lid, there is a cooking container shaped like a bento box with a lid on the main body. An example of a home page where such a cooking container is disclosed is listed as Non-Patent Document 1. The lid of the container mentioned in this non-patent document 1 can be turned upside down to form a dish-like shape with raised walls around it, and although there is a handle on the main body side, there is no handle on the lid side, and the lid is just that. It only serves as a lid or a plate-like container on which rice, side dishes, etc. are placed.

However, since it is better to carry as little luggage as possible when camping or mountain climbing, a multifunctional cooking container is desired in order to reduce the amount of luggage. Therefore, it is envisaged that by providing the lid of the lunch box-shaped cooking container of this non-patent document 1 with a function as a frying pan, the functionality will be enhanced so that there is no need to prepare a separate frying pan. However, in reality, the lid of a cooking container like the one in Non-Patent Document 1 does not have a handle, so even if it is heated, it will be too hot to handle the lid with bare hands. It could not be used as a cooking utensil.
In view of these problems, the present invention provides a lid member and a handle for use as a frying pan with a handle by inverting the lid of a cooking container without a handle and attaching the handle to the lid member via an attachment. It provides a combination with attachments .

In order to solve the above-mentioned problems, a first means is an attachment for inverting a metal lid member of a cooking container to use it as a frying pan with a handle, the lid member standing up when it is inverted. an engaging part that engages with the upper end of the peripheral wall and the inner surface of the peripheral wall that is continuous from the upper end of the peripheral wall; a support part that supports the top plate part of the lid member that is placed at the bottom position by inverting it from the lower surface; and the engaging part and a connecting part that connects the supporting part, and a handle is attached to the connecting part.
By engaging the engaging portion with the upper end of the peripheral wall and the inner surface of the peripheral wall continuous from the upper end of the peripheral wall, and supporting the top plate portion of the lid member from the bottom surface with the supporting portion, the lid member that is upside down can be supported in a cantilever shape by the attachment. It will be done.
With this, the attachment can be attached to the peripheral wall of the cooking container while the lid is turned upside down, and the user can separate the lid by grasping the handle attached to the connection part of the attachment. Since it can be supported like a beam, the lid member can be used as a frying pan.
The engaging part, the supporting part, and the connecting part of the attachment may be constructed integrally, or may be constructed by combining a plurality of members. The material of the attachment is preferably a light and heat-resistant material. Light metals such as aluminum alloys and titanium alloys are preferable. It may also be made of highly heat-resistant plastic. Examples of plastics include fluororesin and melamine resin. Alternatively, it may be made of ceramic.
The handle to be used must be attached to the connecting part, and must be fixed so that it does not swing up and down with the connecting part as a starting point, at least when lifted. When attaching the handle to the coupling part, the handle may be detachable from the coupling part or may not be detachable from the coupling part.

Further, as a second means, the connecting portion is formed with an abutting portion that abuts the outer surface of the peripheral wall of the lid member during use.
Theoretically, it is possible to support the lid member in a cantilever shape using only the engaging part and the support part due to its own weight, but when using the lid member as a frying pan, it is necessary to move it back and forth, left and right, so it is possible to It is necessary to reduce looseness between the lid member and the attachment. Therefore, by forming the contact part that contacts the outer surface of the peripheral wall of the lid member in this way, the engaging part contacts the inner surface of the peripheral wall, and the contact part of the connecting part contacts the outer surface of the peripheral wall, so that the peripheral wall The lid member supported by the attachment is stabilized by being clamped from the inside and outside.
Further, as a third means, the abutment portion is configured to have a shape that follows the shape of the outer surface of the peripheral wall of the lid member.
If the abutting part has a shape that follows the shape of the outer surface of the peripheral wall of the lid member, the abutting part will come into contact with the peripheral wall of the lid member at a plane rather than a point, and the lid member will be better supported by the attachment. This will increase the stability of

Moreover, as a fourth means, the handle is configured to be attachable to and detachable from the connecting portion.
In this way, 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, becomes more compact.
Further, as a fifth means, the handle used to support the main body of the cooking container is removed and attached to the connecting portion for use.
This eliminates the need to prepare a unique handle for the attachment, reducing the amount of luggage the user has to carry.

In the above invention, the attachment can be attached to the peripheral wall of the cooking container with the lid member upside down, and the user can hold the lid member by grasping the handle attached to the connection part of the attachment. Since it can be supported in a cantilevered manner, the lid member can be used as a frying pan.

Hereinafter, specific embodiments of the present invention will be described based on the drawings.
As shown in FIGS. 1 to 4, the attachment 1 of this embodiment is a solid block made by extrusion molding of an aluminum alloy. In the following description, the left direction of the attachment 1 shown in FIG. 2 will be referred to as the front.
Since the attachment 1 is an extrusion molded product, the cross section in the left and right width direction basically appears in the same shape. The dimension of the attachment 1 in the left-right width direction is 40 mm in this embodiment. The attachment 1 includes an engaging part 2 disposed above in use, a connecting part 3 extending downward from the engaging part 2, and a supporting part 4 protruding forward from a lower position of the connecting part 3. There is. On the back surface (rear surface) of the attachment 1, a grip contact surface 5 is formed in which the 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 configured as one plane as a whole, and is arranged substantially vertically when the attachment 1 is in use.
The engaging part 2 is formed to bend and protrude forward from the upper end of the connecting part 3 in a "dog" shape when viewed from the side, and in the left and right width direction, it has an appearance of an upside-down groove with a length of 40 mm. exhibits. Inside the engaging part 2, there is a vertical surface 2a that is arranged vertically when the attachment 1 is used, a ceiling surface 2b that is arranged downward from the top end of the vertical surface 2a, and a ceiling surface 2b that is arranged diagonally forward and downward from the bottom end of the ceiling surface 2b. Three surfaces of the guide surface 2c are formed to face each other.
The connecting portion 3 is a plate whose front and back sides are parallel to each other, that is, it has a flat plate shape. The boundary between the engaging part 2 and the connecting part 3 is not clear, and although they are adjacent to each other, they are in a relationship that gradually and continuously smoothly transitions from one region to the other. In this embodiment, the connecting portion 3 has a thickness of 4 mm, for example.
As shown in FIG. 3(a), 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 inclined surface 7 extending diagonally forward and upward from the lower end of the grip contact surface 5. Consists of. The shelf surface 6 has a shape obtained by cutting out the inner circumferential surface of a cylinder, which is straight in the left-right width direction and curved upward in a direction perpendicular to the width direction. The slanted surface 7 is configured to be a flat surface. A lid contact portion 8 extending in the width direction is formed at a 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 has a ridged appearance. A flat lid contacting surface 8a is formed on the upper surface of the lid contacting portion 8. In this embodiment, the lid abutting 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 hollow portion 9 cut into a substantially arch shape is formed at the center of the support portion 4 in the left-right width direction in order to reduce weight and prevent deformation. A handle bearing part 10 is formed in the transition region of the handle contact surface 5 from the engaging part 2 to the connecting part 3. The handle bearing portion 10 has an outer shape that bulges rearward from the handle contact surface 5 in a ridge shape, and a tunnel-shaped bearing hole 11 with a circular cross section is formed across the left and right width directions. Since the handle bearing part 10 is an extrusion molded product, the cross-sectional shape of the handle bearing part 10 appears to be the same as that of the attachment 1. The handle bearing portion 10 of the present embodiment has a completed shape by cutting the portions formed on both sides during molding so that they are flush with the handle contact surface 5.

Next, the lid 14 of the cooking container 13 to which the attachment 1 is attached will be explained.
As shown in FIG. 4, the lid 14 is a part of a portable aluminum alloy cooking container 13. The cooking container 13 as a whole has a rectangular parallelepiped shape with rounded corners and 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 placed.
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 as a plate for receiving cooked rice or side dishes. The container body 15 is composed of a bottom plate 18 having a similar shape to the lid 14, and a main body wall 19 that is relatively higher than the lid wall 17 that stands up from the bottom plate 18 and surrounds the entire periphery of the bottom plate 18. The container body 15 is used, for example, as a deep dish for adding water and rice when cooking rice or for boiling water.
A handle 21 is attached to the side surface of the container body 15 via a bearing fitting 20. As shown in FIGS. 4 and 5, the handle 21 is constructed by bending a single wire, and has a substantially trapezoidal handle portion 21a and an internal angle of about 80 degrees with respect to the handle portion 21a. It is composed of a pair of bent portions 21b rising from the tip of the handle portion 21a, and a pair of rotation shaft portions 21c with the tips of the bent portions 21b bent at right angles so as to face each other. The outer periphery of the handle portion 21a is covered with a cover 23 made of synthetic rubber. The outer distance 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 hole 22 of the bearing fitting 20 of the container body 15, the handle 21 can swing vertically about the rotating shaft portions 21c. When using the handle 21 of the container body 15, as shown by the solid line in FIG. When the handle 21 is not used, that is, when it is to be stored, the handle 21 can be held in a cantilevered manner by flipping it upward with the rotation shaft 21c as the rotation base as shown by the virtual line in FIG. 21a is placed on the upper surface of the lid 14 in a lying state.

Next, a method for attaching the attachment 1 for using the lid 14 of the cooking container 13 as a frying pan will be described.
The rotating shaft portion 21c of the handle 21 of the cooking container 13 can be removed 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 it is as the handle of the attachment 1.
As shown in FIGS. 2 and 3, contrary 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 apart from each other. 21c is attached so that the bent portions 21b hang down from both sides of the bearing hole 11 of the handle bearing portion 10. In the attached state, the bent portion 21b fits within the width of the attachment 1. Furthermore, although the length of the bent portion 21b is configured to be approximately 28 mm, since the distance from the center of the bearing hole 11 to the lower end of the grip contact surface 5 is approximately 30 mm in the attachment 1 of the embodiment, the bent portion 21b is also gripped. It does not protrude downward from the hand grip contact surface 5 and fits exactly within the area of the grip contact surface 5. In other words, the handle 21 is attached so that the area defined by the pair of rotating shaft portions 21c and the pair of bending portions 21b of the handle 21 fits within the handle contact surface 5 without protruding from it. When the handle 21 is attached to the attachment 1, assuming that the handle contact surface 5 is arranged vertically, the handle 21 has the bent part 21b as the base and the handle part 21a rearward approximately horizontally (actually, in the horizontal direction). (the state shown in FIG. 3(b)).
With the handle 21 attached to the attachment 1 in this way, the user holds the handle 21a of the handle 21 and presses it against the upper edge 17a of the lid wall 17 of the inverted lid 14 as shown in FIG. 6(b). The engaging portion 2 is engaged so as to be hooked thereto.

For more details, run as follows.
The height of the lid wall 17 of the lid 14 is longer (higher) than the distance P2 between the open end side lower end of the engaging part 2 and the lid abutting surface 8a shown in FIG. Even if it is brought close to the wall 17, the engaging portion 2 will interfere with the lid wall 17. Therefore, in order to avoid such interference, first approach the upper edge 17a of the lid wall 17 relatively obliquely from above, and engage it along the guide surface 2c as shown in FIG. 6(a). The inside of the groove of the joint part 2 is guided toward the upper edge 17a, and the upper edge 17a is brought into contact with the ceiling surface 2b inside the engaging part 2.
Next, 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 side of the pan (which will become the bottom of the bread). With the upper surface of the lid abutting 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 part 2 are in contact with each other as shown in FIG. 6(b), and at the same time, the outer surface of the lid wall 17 is It faces the front surface 3a of the connecting portion 3. In other words, 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 back.
In this state, the attachment 1 is correctly attached to the lid 14. 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 handle 21 can be attached to the handle-less lid 14 via the attachment 1 and used as a frying pan for cooking, thereby improving the functionality of the cooking container.
(2) Since the handle 21 is originally attached to the cooking container 13, as long as the cooking container 13 and the attachment are provided, the cooking container 13 can be given a new function that allows the lid 14 to be used as a frying pan. There is no need to prepare a handle.
(3) The attachment 1 only supports the upper edge 17a of the lid wall 17 of the lid 14 with the upper engagement part 2, and supports the top plate 16 from below with the lid contact part 8 at the tip of the support part 4. The weight of the lid 14 allows the lid 14 to be held in a cantilevered manner on the outside. This method eliminates the need for a chuck device or fixing parts such as screws for attaching the attachment 1 to the lid 14, and the weight of the attachment 1 is reduced.
Further, since the attachment 1 is simply hung on the lid wall 17, it is easy to attach and detach.
(4) The attachment 1 supports the lid 14 with the engaging part 2 and the support part 4, and at an intermediate position, the lid wall 17 is sandwiched between the vertical surface 2a of the engaging part 2 and the front surface 3a of the connecting part 3 from the front and back. Since the cover wall 17 is not only supported but also sandwiched between the surfaces, it contributes to stably fixing the attachment 1 at this position.
(5) The handle 21 swings up and down using the rotation shaft 21c of the handle 21 as a base, but when it swings downward, the pair of bent parts 21b of the handle 21 come into contact with the handle contact surface 5 on the back side of the attachment 1. Therefore, 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.

The embodiments described above are merely described as specific embodiments for illustrating the principles and concepts of the present invention. That is, the present invention is not limited to the above embodiments. The present invention can also be embodied in the following modified aspects, for example.
- The above attachment 1 is merely an example, and the present invention can be implemented in various forms.
For example, a handle 32 as shown in FIG. 7 may be attached to an attachment 31 as another embodiment. This is different from the handle 21 of the cooking container 13, but since it is similarly made of wire, it is not heavy to carry and can be removed, so the handle 21 of the cooking container 13 can be used as is for the container body 15. , this type of attachment 31 can be used for the lid 14. A bearing portion 34 extending in the vertical direction is integrally formed on the back surface 33 of the attachment 31. The bent tip 32a of the handle 32 is used by inserting it into the bearing hole 34a of the bearing part 34 from below.
Alternatively, it may be implemented as shown in FIG. 8, for example. Similarly, since it is made of wire, it is not heavy to carry and can be removed. FIG. 8 shows a case where the attachment portion for attaching the handle 35 is not a through hole. A pair of L-shaped protrusions 43 are integrally formed on the back surface 42 of the attachment 41 so as to face each other. The protrusion 43 and the back surface 42 form a groove 44 that extends vertically. A handle 45 is accommodated within this groove 44. Since the handle portion 45a of the handle 45 is wider than the interval between the left and right grooves 44, the handle portions 45a are brought close to each other during installation to apply a biasing force, and the biasing force increases the elasticity when the handle portion 45a returns to its original position. The handle 45 is held between the grooves 44 by this. The first bent portion 45b is housed in the groove 44, and is prevented from falling off in the vertical direction by the handle portion 45a and the second bent portion 45c.
Alternatively, it may be implemented as shown in FIG. 9, for example. FIG. 9 shows an example in which the handle 53 is fixed to the back surface 52 of the attachment 51 with screws 54. With this configuration, the handle 53 does not come off the attachment 51, and the operability of the frying pan is improved.

- In the above embodiment, the shapes of the engaging portion 2 and the supporting portion 4 are merely examples.
- In the above embodiment, it is stated that the lid 14 can be used as a frying pan by using an attachment, but this refers to a frying pan as the main usage, and in addition to being used as a frying pan, it can be used as a conventional container such as a plate. This does not exclude the function of
- In the above embodiment, the material is made of aluminum alloy, but other metals, plastics, and ceramics may be used as the material.
- In the above embodiment, the attachment 1 was placed in a non-curved part of the lid wall 17 of the lid 14, but the shape of the engaging part 2 and the connecting part 3 was changed to be curved so that it could be attached at a curved position. It may also be carried out.
- In the above embodiment, the attachment 1 is manufactured by extrusion molding and cutting, but a molding method such as pouring the material into a mold may also be used.
- In the above, the hollowed out part 9 was formed to reduce weight and prevent deformation, but the hollowed out part 9 is not essential. Furthermore, it is also possible to implement it by cutting out the thickness to a larger extent than the attachment 1 described above. Further, the portions other than those mentioned above may be cut out.
