Tubular container made of synthetic resin

Abstract

A tube container which enables to make full use of its contents, and also to reduce the amount of material for forming the container by shortening the length from the upper end of its trunk portion to an opening. Said container comprising, a tube member (1) having a truck portion (3) which is elastically squeezable, and a wide-mouthed neck portion (4) erecting from the trunk portion (3); a top wall (5) closing a top surface of the neck portion (4) and having a discharge port (6), said top wall (5) also having a peripheral portion connected directly or indirectly to a top end of the neck portion (4), from which the peripheral portion is made undetachably: a cover plate (9) which is provided rotationally with respect to the neck portion (4) and having a plug (11) for closing the discharge port (6), said plug depending from an underside of the cover plate (9): wherein the top wall (5) has a first breaking line (12) which is formed within the peripheral portion of the top wall (5), and a knob (13) for tearing the first breaking line (12), said knob (13) is formed on the top wall (5) within the first breaking line (12).

Description

[0001] This application is a divisional application of China No. 00800966.X invention patent application. technical field [0002] The present invention relates to an invention of a tubular container made of synthetic resin. Background technique [0003] This container is composed of a tubular main body and a cap main body. The tubular main body has a neck with a smaller diameter standing on the upper end of the thin-walled cylindrical part through the shoulder. The cap main body is closed and screwed on the top wall with an extrusion hole. A cover plate that can be turned by a thin-walled hinge is provided on the upper surface of the fitting cylinder outside the neck and on the peripheral edge of the top wall. Tubular containers with this structure are widely used. [0004] However, in this container, in order to reliably connect the cap main body to the outside of the neck, it is necessary to form a screw thread with a certain length on the outside of the neck and the insi...

Problems solved by technology

However, this prior art is just the same as the technique of pulling the above-mentioned handle when starting to use the container, removing the plate portion for removal, and opening the container. In the case of taking out the content and removing the bottom plate, will the installation of the top wall removal device on the container cause trouble to the normal operation from the start of use of the container to the removal of the top wall, such as the operation of squeezing liquid from the extrusion hole?
