Abstract

<P>PROBLEM TO BE SOLVED: To make it possible to open an opening by pinching and pulling an opening tongue 5 and to use cream-like contents which remains inside a shoulder section up to the last when used to the last. <P>SOLUTION: A cutting-off strip 6 making carbon fiber and nylon or the like as a core material 7 and having a cutting-in section 8 and the opening knob 5 are juxtaposed near the boundary between the drum section 1 of a synthetic resin-made tube container filled up with the cream-like contents and the shoulder section 3. Moreover, there is provided a cutting-off residual section 9 for preventing the spilling of the contents by being torn off when opened. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to a synthetic resin tube container that is intended to reduce volume during disposal.

In a conventional plastic tube container filled with creamy contents such as cosmetics, the shoulder part has high strength due to restrictions in the design and other manufacturing methods, and it is difficult to squeeze to the end with the power of a woman in use, and the creamy contents are used up completely It was difficult.

Cutting the torso with scissors, etc. can be used up to the end, and the satisfaction of consumers is obtained, but the cutting tool is cumbersome to remove to remove the creamy contents attached at the time of cutting, and also under care The current situation is that few consumers run with risk.

Containers having an opening mechanism at the top (Japanese Patent Laid-Open No. 2001-122111, Japanese Patent Laid-Open No. 2001-12212) are also seen, but the opening is concentric with the top plate, so if the top plate diameter does not have a certain size, It seems that it is difficult to get ugly without entering.

For consumers who have purchased expensive cosmetics, not leaving any leftovers is consistent with the “mottle” spirit, a feeling that Japanese people have nurtured for a long time, and reducing the volume of garbage when discarding containers It also contributes to reducing the burden of processing.

Using up the cream-like contents to the end in a synthetic resin tube container such as cosmetics eliminates consumer dissatisfaction, and also leads to a reduction in the volume and weight of garbage when discarded.

In the vicinity of the boundary between the body portion 1 and the shoulder portion 3 of a synthetic resin tube container such as toothpaste and cosmetics, a cut band 6 having a cut portion 8 having a core 7 made of carbon fiber, nylon thread or the like strong against tensile force is provided. A synthetic resin tube container having a structure that can be opened by pinching and pulling the opening knob 5 is proposed.

It can be easily opened by elderly people, women, and children who could not be squeezed to the end.

Alternatively, the body can be used up to the end by cutting the body with scissors, etc., but the cutting tool is troublesome to remove the cream-like contents attached at the time of cutting, and it is also necessary to carry out it with danger during cleaning. It is welcomed by users who have been troublesome.

At the time of manufacturing a tube container made of synthetic resin such as toothpaste and cosmetics, a cut band 6 having a cut portion 8 with a nylon thread as a core material 7 is provided in the vicinity of the boundary between the trunk portion 1 and the shoulder portion 3.

An unsealing knob 5 is provided for easy opening, and a notch 8 is also provided at the knob base.

By cutting off at the time of opening, the remaining portion 9 is left about 1/5 of the circumference of the trunk so that the contents are not scattered.

The range of use of tube containers made of synthetic resin is a wide range of packaging forms such as daily items such as toothpaste, cosmetics, household medicine, spread foods.

The reduction of the contents remaining in the containers that are discarded after use leads to a reduction in the volume and weight of the garbage, thereby contributing to a reduction in the processing burden on the treatment plant.

Promoting product development that eliminates consumer dissatisfaction leads to an improvement in the corporate image of manufacturing and sales.

It is a container main body figure which shows a present Example. It is a cutting band and an opening knob part plane enlarged view which show a present Example. It is a cut strip part horizontal direction sectional view which shows a present Example. It is a cut | disconnecting band part perpendicular | vertical sectional view which shows Claim 1 in a present Example. FIG. 3 is a cross-sectional view in the direction perpendicular to a cut-off strip portion showing claim 2 in the present embodiment. It is a main body figure at the time of opening which shows a present Example.
