AI Technical Summary

Benefits of technology

The interlocking layer design enhances corner strength and resistance to external impacts by evenly distributing forces across both layers, reducing the likelihood of deformation and improving overall structural integrity.

Problems solved by technology

However, since fluid pressure is introduced to force the molten tube against the walls to create predetermined spacing between the walls, problems will be encountered for corner portions of the article where its surface geometry experiences sudden changes in orientation and / or plane of extension.
However, with the increased spacing between the walls, the corner portion is more vulnerable to external impact that easily results in deformation or dent of the corner portion.

Embodiment Construction

[0065]In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word “comprise” or variations such as “comprises” or “comprising” is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.

[0066]Referring now to FIG. 1, the first embodiment of the present invention is a blow molded container for storing various tools and accessories, in particular a portable electrical drill with various drill bits. The blow molded container includes a main member 20 forming a tool cavity. As illustrated in FIG. 1 the main member 20 is consisted of a base member 22, and a lid member 24 hingedly connected to the based member 22 by two hinges 28. Preferably, for each hinge 28 one piece is integrally formed with the base member 22 and the other piece is integr...

Abstract

A blow molded container includes a main member comprising a top, a first side orthogonal to the top, a second side orthogonal to the top, an external wall, and an internal wall defining a tool cavity. A corner portion is defined as a portion of the main member and includes least a first layer and a second layer. The first layer forming at least a part of the external wall and the second layer forming at least a part of the internal wall. The first layer and the second layer are adhered together to along a predetermined pattern to form at least a first line segment and a second line segment on one of the internal wall or the external wall of the corner portion.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of U.S. patent application Ser. No. 15 / 316,446 filed on Dec. 5, 2016, which is a national stage filing under 35 U.S.C. 371 of International Application No. PCT / CN2014 / 083772 filed on Aug. 6, 2014, which is a continuation of International Application No. PCT / CN2014 / 079415 filed on Jun. 6, 2014, which are all hereby incorporated by reference herein in their entireties.FIELD OF THE INVENTION[0002]This invention relates generally to the field of blow molded plastic containers, and more specifically to corner design of a generally rectangular blow molded plastic container that such corners have improved resistance to deformation.BACKGROUND OF THE INVENTION[0003]Many types of articles, such as toolboxes for a portable power tool, are manufactured by using blow-molding techniques to produce a double wall body. By producing an article in this manner, one is able to easily create an article that has two, hard plas...
