Liquid container

Abstract

A liquid container including a container body with a thermal insulation function for storing a liquid, a lid member detachably attached to an upper end opening of the container body, and a carrying handle rotatably and detachably attached to an upper part of the container body, wherein a handle attaching part of the carrying handle is engageable with a handle mounting part of the container body to prevent the carrying handle from being detached from the container body when the carrying handle is used to hang the liquid container, and the handle attaching part of the carrying handle is releasable from the handle mounting part of the container body to permit the carrying handle to be detached from the container body when the carrying handle is not used to hang the liquid container.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims, under 35 USC 119, priorities of Japanese Patent Applications No. 2004-379504 filed Dec. 28, 2004, No. 2004-379510 filed Dec. 28, 2004 and No. 2004-378474 filed Dec. 28, 2004, disclosures of which, inclusive of the specifications, claims and drawings, are hereby incorporated by reference herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a structure of a liquid container with a thermal insulation function suitable for containing coffee, tea, hot water or the like liquid.

AI Technical Summary

Benefits of technology

The present invention provides a liquid container with a carrying handle that can be easily removed or disassembled for safety and convenience. The carrying handle is attached to the container body in a way that it cannot be detached when in a usable condition but can be easily detached when in an unusable condition. The container body has a valve unit and / or a liquid level pipe which can be easily removed or disassembled for cleaning or replacement. The carrying handle can be detached from the container body when at least one predetermined component part among the component parts has been displaced or detached from its fixed position. The liquid container also has a simple and convenient design that allows for easy handling and carrying.

Problems solved by technology

However, once placed, the liquid container is generally not moved for a while.

Then, the carrying handle is unnecessary during that time.

In the case of the liquid container disclosed in JP-A-2001-48181, however, the valve unit is secured to the bottom of the body case by fastening means such as screws as described above and cannot be removed without a tool such as a screw driver.

That is, the valve unit cannot be removed easily by a user so that the approval of NSF cannot be obtained.

However, when the liquid container is used for a long time, the first and second packing seals of silicone rubber adhere to the glass liquid level pipe.

If the user tries to remove the packing seals from the liquid level pipe for washing, the packing seals will be torn and will not be able to be used anymore.

Therefore, the number of parts and the number of assembly steps are large, and the production cost is high.
