Description

  The present invention relates to a thermal insulation cover for a cooler box.

  The conventional cooler box is known as a well-known heat insulation container, and is used for fishing, the outdoors, etc.

Unexamined-Japanese-Patent No. 2005-329962

  Conventional cooler boxes are required to improve their heat insulation.

  The present invention is to provide a thermal insulation cover for a cooler box that can improve the thermal insulation of the cooler box.

  In order to solve the said subject, the heat insulation cover of 1 aspect of this invention is equipped with the cylindrical main body cover which has the flexibility which can cover the outer peripheral surface of the main-body part of a cooler box. The main body cover has at least one heat insulating portion capable of covering at least a part of the outer peripheral surface of the main body portion.

  In the case of the heat insulating cover of such an aspect, at least a part of the outer peripheral surface of the main body portion of the cooler box is covered with the heat insulating portion, so that the heat insulating property of the cooler box can be improved.

  When the main body portion of the cooler box is a rectangular box and the outer peripheral surface of the main body portion has the first surface, the second surface, the third surface and the fourth surface, the main body cover is The first panel and the second panel disposed opposite to each other in one direction and the third panel and the fourth panel disposed opposite to each other in a second direction orthogonal to the first direction can be provided. . At least one of the first panel, the second panel, the third panel and the fourth panel may have a heat insulating part. The first panel can be in close contact with the first surface of the main body and can have a first end in the second direction and a second end opposite to the first end. The second panel can be in close contact with the second surface of the main body, and can have a first end in the second direction and a second end opposite to the first end. The third panel can be in close contact with the third surface of the main body, and can have a first end in the first direction and a second end opposite to the first end. The fourth panel can be in close contact with the fourth surface of the main body, and can have a first end in the first direction and a second end opposite to the first end.

It is possible to further include a pair of second connection portions that respectively connect the first and second ends of the four panels.

  When the first panel, the second panel, the third panel and the fourth panel have a heat insulating part, the first panel, the second panel, the third panel and the fourth panel are decorative panels superimposed on the heat insulating part It is possible to have the composition which further has In the case of the heat insulating cover of such an aspect, since the decorative panel is provided separately from the heat insulating portion, the decorative panel can be freely designed without being restricted by the material of the heat insulating portion.

  The main body cover may further include an engagement portion engageable with the projection provided on the outer peripheral surface of the main body portion. In the case of the heat insulating cover of such an aspect, the main body cover is engaged with the projection of the main body portion by the engagement portion, so that the main body cover is prevented from slipping off.

  The engaging portion may be configured to have a recess in which the protrusion can be inserted and removed in the protrusion direction of the protrusion, and a connecting portion connecting the upper edges of the recess and being hooked on the protrusion. is there. In the case of the heat insulating cover of such an aspect, the engaging portion can be hooked to the projection only by inserting the projection of the main body portion into the recess of the engaging portion and hooking the connecting portion to the projection.

  The heat insulation cover of any of the above-described aspects can be configured to include a flexible cover that can cover the cover of the cooler box. The lid cover can be configured to have a panel capable of covering the outer surface of the lid. It is possible that this panel has a heat insulation part. According to the heat insulation cover of such an aspect, since the outer surface of the lid of the cooler box is covered by the heat insulation portion of the cover, the heat insulation of the cooler box can be improved.

  The panel of the lid cover may be configured to further have a decorative panel superimposed on the heat insulating portion. In the case of the heat insulating cover of such an aspect, since the decorative panel is provided separately from the heat insulating portion, the decorative panel can be freely designed without being restricted by the material of the heat insulating portion.

  The lid cover may be configured to further include an engaging portion provided on the panel and engageable with the lid.

  The engaging portion may be configured to have a pair of bag bodies or locking belts that can be hooked on both ends of the lid. According to the heat insulating cover of such an aspect, the lid cover can be easily hooked and attached to both ends of the lid by the engaging portion.

  The pair of bag bodies can be configured to have holes through which the protrusions at both ends of the lid can project. In the case of the heat insulating cover of such an aspect, the projections on both ends of the lid project from the holes of the pair of bags to prevent the bags from being inadvertently detached from the both ends of the lid. it can.
