Toothpaste container

Abstract

A toothpaste container includes a flexible tube and a cap on the front end thereof. The toothpaste is filled into the toothpaste container through an opening on rear end thereof. By squeezing the flexible tube, toothpaste is out through a tube hole on front end thereof. The invention is characterized in that the tube hole of the flexible tube is rectangular and is at an angle of 20-70 degrees to the horizontal in lateral view. Threads are arranged on the outer wall of the tube hole for combing with the cap.

Description

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention provides a toothpaste container, especially to a kind of toothpaste container with improved tube hole so that toothpaste being squeezed has larger contact area with the brush and attaches on the brush more firmly. Moreover, the amount of toothpaste being used is also reduced.

(b) Description of the Prior Art

Generally, most of toothpaste containers are made of two kind of material-metal or rubber. Recently, rubber replaces metal due to the requirements of low cost and light weight. Refer to FIG. 1, the toothpaste packaging is a flat tube (a) with a round tube hole (a1). Threads (a2) are arranged on the outer wall of the hole (a1). Toothpaste is filled into the tube (a) through the opening (a3) on the rear end of the tube (a). Then the opening (a3) is closed by welding or high frequency welding and a cap (c) is threaded into the front end of the tube (a). While being used, press the tube (a) to squeeze the toothpaste (b), through the round tube (a1) on the brush (d). The toothpaste (b) is cylindrical so that the contact area between it and the brush (d) is quite limited and the toothpaste (b) is easy to come off. Moreover, it's often for users to squeeze too much amount of toothpaste (b) on the brush (d) and cause some kind of waste. There is a space for improvement of the toothpaste container.

SUMMARY OF THE INVENTION

Therefore, it is a primary object for the present invention to provide a toothpaste container that makes the toothpaste attach on the brush directly with larger contact area so as to avoid the problem of easily falling off. Also the amount of the toothpaste being squeezed is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Refer to FIG. 2 & FIG. 3, a toothpaste container according to the present invention includes a flexible tube 10 and a cap 20 on the front end thereof. A tube hole 11 of the flexible tube 10 is in rectangular shape. In lateral view, the tube hole 11 has a slope inclined at 20 to 70 degrees to the horizontal. And threads 12 on the outer wall of the tube hole 11 for connecting with the cap 20.

Refer from FIG. 4A to FIG. 5B, the toothpaste being squeezed from the round hole 3 of the conventional toothpaste container 1 is different in shape from that squeezed from the rectangular tube hole 11 of the present invention. The cross section of the toothpaste 2 from the present invention is rectangular while the cross section of the toothpaste 2 from conventional containers is round. The contact area between the tubular-shaped toothpaste 2 and the brush 4a of the toothbrush 4 is less than that between the rectangular toothpaste 2 and the brush 4a of the toothbrush 4 thus the later has larger adhesion and won't come off from the brush 4a. Moreover, the cross sectional area of the rectangular toothpaste 2 is less than that of the round-shaped toothpaste 2 so that while both are squeezed in a certain length, the amount of the rectangular toothpaste 2 is less than that of the round-shaped toothpaste 2. Through the increasing of the usage times, the amount of the toothpaste 2 is effectively saved.

Refer to FIG. 6, people always hold the holding the toothpaste container 1 at an angle ranged from 20 to 70 degrees while squeezing the toothpaste 2. In lateral view of the present invention, the tube hole 11 already inclines 20 to 70 degrees so as to make the toothpaste 2 firmly attached on the brush 4a of the toothbrush 4.

It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.

Claims
