Description

[Detailed description of the invention]

[0001]

[Industrial application] The present invention is intended to keep food at an appropriate temperature in places where time is required from cooking to serving meals in group lunches at schools and hospitals, and where the places are far away. The present invention relates to an insulated food can.

[0002]

2. Description of the Related Art Conventionally, a heat insulating food can has a structure in which a heat insulating material is provided in a metal outer shell. However, this type is heavy and difficult to clean, and has a poor heat retention because it uses a metal material having high thermal conductivity.

On the other hand, there has been provided an insulated food can having an outer shell formed of a synthetic resin, provided with a heat insulating material therein, and directly containing food, but has a drawback that when heat sterilized during washing, it expands due to thermal expansion. .

[0004] A tablet (so-called snap-in tablet) is provided on the side surface.
Insulated food cans that fix the main body and lid by providing a `` rattling sound '' due to vibration when not in use, and also have the drawback that the tablet moves during cleaning and gets caught in the washing machine. It is.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has an excellent heat retaining property, a good cleaning property, and prevents a tablet body and a handle from generating a rattling sound. It is intended to provide cans.

[0006]

SUMMARY OF THE INVENTION A heat-insulating food can according to the present invention has a main body and a main body lid filled with a heat insulating material inside a shell made of synthetic resin, and is housed inside the main body and the main body lid. A metal can and a lid for a food can, a lock provided on the main body for locking the lid for the main body, and a handle provided on the main body, the main body having the lock when not in use. Protrusions for locking the body and the handle are formed. Further, it is preferable that a concave portion for drawing out is formed in an upper portion of the inner surface of the container.

[0007]

In the heat retaining food can configured as described above, the main body and the lid for the main body are made of a synthetic resin and are filled with a heat insulating material, so that the heat retaining property is very excellent.

In addition, since the food can and the food can lid are made of metal, there is no danger of deformation when heated to 100 to 150 ° C. when drying after washing. In addition, since a concave portion is provided in the upper portion of the inner surface of the food can and the concave portion is easily pulled out by putting a finger on the concave portion, the separating operation from the main body at the time of washing can be performed quickly and easily.

In addition, since the lock body and the handle can be locked to the projection of the main body when not in use, no rattling sound is generated by vibration. In addition, the tablet and the handle do not move during the washing and are not caught by the washing machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 to 4, a heat-insulating food can of the present invention includes a main body 1 and a main body lid 10, a food can 20 and a food can lid 22, and a tablet provided on the main body 1, a so-called snap-in lock 3.
0 and a handle 35.

The main body 1 is made of a synthetic resin and has an outer shell 2 in the form of a cylindrical container having a large diameter at the upper part, an inner shell 3 in the shape of a cone having an upwardly expanding diameter, and both shells 2, 3. It is formed from a heat insulating material 4 such as styrene foam filled in the space.

As shown in FIG. 4, the outer shell 2 and the inner shell 3 may be independent shell materials, in which a heat insulating material is inserted into a space formed when the two are overlapped, or may be constituted by an outer shell and an inner shell. After the heat insulating material is inserted into the space, the edges of the outer shell and the inner shell may be integrated by a known technique such as high-frequency induction heating welding, ultrasonic welding, vibration welding, spin welding, and solvent bonding. Of course, it can also be manufactured by a method of injecting a heat insulating agent after joining the outer shell and the inner shell.

A cover 10 for the main body, an outer shell 11 and an inner shell 13 made of the same synthetic resin as the main body 1, and a heat insulating material 15 such as styrene foam filled in the space formed by the two shells 11, 13. Is formed. Like the main body, the main body lid can be assembled from an independent outer shell and inner shell material, but from the viewpoint of workability during use, it is more convenient to form an integrally molded product. The protruding portion 14 of the inner shell 13 projects from the outer shell 11.
An undercut portion 12a is formed on the knob 12 in contact with.

The food can 20 is formed in the shape of a cone-shaped container which is made of metal (for example, aluminum) and whose diameter is increased upward. In the upper part of the food can 20, an annular concave groove 21 protruding outward from the inner shell 3 of the main body 1 is formed.

The lid 21 for a food can is made of the same metal as the food can 20 and is formed so as to be fitted to the food can 20.

In FIG. 5, the first arm 31 of the snap-in lock 30 has a plurality (four in the illustrated example) of lock projections 5 projecting circumferentially on the upper outer periphery of the outer shell of the main body 1. Is pivoted to. In the middle of the first arm 31, the second arm 3
The upper end of the arm 32 is pivotally connected to the lower end of the arm 32.
When the snap lock 30 is locked (the state on the left side in FIG. 2), a hook 33 is provided to hook the flange 10a of the cover 10 for the main body. The outer shell 2 of the main body 1 has a snap lock 30
At the time of unlocking (the state on the right side in FIG. 2), the lower edge 32a of the second arm 32 is locked, and the second arm 32 swings due to vibration to generate a "patter", Locking rib 6 for preventing the lock body and handle from moving and being pinched by the washing machine
Is protruding.

In FIGS. 6 and 7, the handle 35 is
The handle 35 is pivotally attached to a handle projection 7 protruding from the upper outer periphery of the outer shell 2 of the main body 1. The handle 35 is formed with a grip portion 36 of a coil lock whose both ends are reduced in diameter. I have. A handle 25 (not shown) is locked on both outer sides of the projection 7, and the grip 26 is pressed against the outer shell 2, and the handle 35 swings due to vibration to “patter sound”. Occurs,
A locking projection 8 is provided to prevent the lock body and handle from moving during cleaning and being pinched by the cleaning machine.

Next, the operation will be described.

The main body 1 and the main body lid 10 are formed of a synthetic resin, and are filled with heat insulating materials 4 and 15 so that the heat retaining property is very excellent.

The food can 20 and the food can lid 22 are made of metal, and can be easily taken out by putting a finger on the annular groove 21, so that the food can be easily cleaned.

The knob 12 of the cover 11 for the main body has an undercut portion 12a, so that the cover 12 can be easily opened.

When the snap lock 30 and the handle 35 are not used, they are locked by the locking ribs 6 and the locking projections 8, respectively. Also, it is possible to prevent the lock body and the handle from moving and being caught in the washing machine during washing.

[0024]

[Effects of the Invention] The present invention is configured as described above, so that the heat retention and cleaning properties are improved, and the tablet body and the handle generate a rattling sound and move during the cleaning. It is possible to prevent the washing machine from being caught.
