Description

{A Container having a removalbe Knob}

The present invention relates to a container having a removable handle, and to a container to which a handle gripped by a person can be attached or detached as needed.

Cooking containers such as pots, rice cookers, frying pans, or coppels used for accommodating and heating foodstuffs, or containers for transporting items, etc., are equipped with handles for gripping while cooking or moving.

For example, in the handle, the cooker's hand is protected from the flame or heat of a fire that heats the cooking container, or oil splashing from the cooking container, and mainly from the side of the body of the cooking container for the convenience of cooking or movement. There are long extensions.

Such a handle not only occupies a large storage space during storage, but also becomes an element that prevents the containers from being stacked up and down with each other.

In order to solve the problem of the container having such a structure, various containers having a configuration in which the handle is detachably configured to attach the handle when in use or when moving and detach the handle when stored have been proposed.

As a container having such a removable handle, there is an invention entitled 'a removable cooking container handle and a cooking container having the same' disclosed in Korean Patent Publication No. 10-1217604 (Document 1).

In the present invention, a support member having a receiving groove is attached to the outer surface of the cooking vessel, and a 'U'-shaped insertion part to be fitted into the receiving groove is formed on the handle, and the insertion part of the handle is inserted into or separated from the receiving groove of the supporting member. By making it possible, it has a configuration for coupling or separating the handle to the cooking container.

Although the cooking container of Document 1 has a simple configuration of the handle and the cooking container and easy detachment operation, it can be used when the cooking container is a pot or rice cooker that only puts ingredients and heats, but the handle is removed in the process of cooking. In the case of a cooking vessel, such as a frying pan, which is gripped and operated such as shaking the cooking vessel, an accident in which the cooking vessel is detached from the handle is high.

As another example of a container having a removable handle, there is an invention named 'frying pan' disclosed in Korean Patent Publication No. 10-1152882 (Document 2).

In the invention of Document 2, a groove penetrating through the rim of the frying pan is formed, the handle is formed with a coupling port surrounding the rim, and a slider penetrating the groove is provided in the coupling port, and the coupling hole of the handle is connected to the rim of the frying pan with the through groove formed. The handle and the frying pan are combined as the slider passes through the through hole while inserting it into the pan.

The frying pan according to the invention of Document 2 provides a slider inside the handle, and has a rotation knob that moves the slider forward and backward from the handle to the through groove of the frying pan, and a cam structure that transmits the rotation of the knob, so the structure of the handle becomes very complicated. In addition, the operation for separating and combining the handle is very complicated, so it is inconvenient to use.

Furthermore, since the tip of the handle with the coupling groove extends over the rim of the frying pan, a part of the handle protrudes into the inside of the frying pan during the cooking process and the food cooked in the frying pan comes into contact with the handle, so the handle must be washed after removing the handle. In addition, there is a problem that the handle is heated during cooking.

In addition, Korean Patent Publication No. 10-1626753 (Document 3) discloses an invention called 'a removable handle for a frying pan'.

In the invention of this document 3, a coupling member having a coupling hole into which the tip of the handle is inserted is attached to the outside of the rim of the frying pan, and the tip of the handle is configured to be inserted into the coupling hole, but a protrusion that expands and contracts at the tip of the handle is provided And the coupling hole of the coupling member is formed with a fixing groove in which the projection is engaged.

The handle is provided with two buttons: a button for engaging the protrusion in the fixing groove by expanding it and a button for releasing the protrusion from the fixing groove by contracting the protrusion.

The frying pan and its handle according to the invention of Document 3 have a very complicated structure because they guide the slide operation of the ball for contraction and expansion of the projections, and provide a structure and several springs and buttons.

In particular, since the handle and the frying pan are coupled and separated by buttons provided on the handle, there is a problem in that an accident occurs when the release button of the handle is accidentally pressed during cooking.
