TECHNICAL FIELD The present invention relates to a multi-stackable tube container having an inclined spouting portion, thereby improving the squeezing out contents and saving the delivery costs.

BACKGROUND ART A conventional tube container has a drawback in that it is impossible to fully squeeze out the contents due to its structure having a horizontal spouting portion.

To solve the drawback, in recent years, a metal tube container provided with a folding line near the spouting portion so that the contents can be completely squeezed out by folding the container along the folding line when a little content is remained has been proposed.

However, such a technology is limited to the metal tube container.

That is, tube containers made of resin through a blow molding process

or an injection molding process cannot employ such a technology.

Furthermore, since the conventional tube containers are designed having upper and lower diameters similar to each other, it is difficult to stack them one another when they are empted.

SUMMARY OF THE INVENTION Therefore, the present invention has made in an effort to solve the above-described drawback of the conventional spout assembly.

It is an object of the present invention to provide a tube container that can easily eject contents by providing an inclined spouting portion.

It is another object of the present invention to provide a tube container that is designed to be stackable, thereby saving the delivery costs.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view of a tube container provided with an inclined spouting portion according to a first embodiment of the present invention; FIG. 2 is a sectional view of a tube container provided with an inclined spouting portion according to a second embodiment of the

present invention; FIG. 3 is a sectional view of a tube container provided with an inclined spouting portion according to a third embodiment of the present invention; FIG. 4 is a perspective view illustrating a stacked state of the tube containers according to the present invention; and FIG. 5 is a view illustrating a tube container sealed.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described more in detail hereinafter in conjunction with the accompanying drawings.

FIG. 1 is a sectional view of a tube container provided with an inclined spouting portion according to a first embodiment of the present invention.

As shown in the drawing, the tube container 1 that is designed to squeeze out contents comprises a tube body 100 defining a cavity 101 and a spouting portion formed on one end of the tube body 100, the spouting portion 200 being inclined.

That is, when squeezing the tube body 100 to eject the content,

the inclined spouting portion allows a user to easily depress a portion where the tube body 100 meets the spouting portion 200 such that the contents can be fully squeezed out.

The spouting portion 200 includes a spouting member 201 defining a spouting hole 202. The spouting member 201 may be closed by a one-touch opening cap 210 or a screw cap.

The other end of the tube body 100 is remained as an unsealed portion 102 through which the content is filled in the tube body 100.

After filling the content in the tub body 100, the unsealed portion 102 is sealed.

As described above, the tube body 100 can be formed through an extruding process, an injection process, or a blow vacuum process.

The operation effect of the present invention will be described hereinafter.

The content is first filled in the cavity 101 and the unsealed portion 102 is sealed.

In this state, after the opening the cap 201, the tube body 100 is squeezed so that the content in the cavity 101 is exhausted through the spouting hole 202.

When a little content is remained in the container 1, the tube body

100 is depressed along the inclined portion of the spouting portion 200, completely ejecting the content in the cavity 101.

As shown in Figs. 2 and 3, the spouting portion 200 can be formed in a variety of designs as far as the spouting portion 200 is inclined.

Fig. 4 and 5 shows an example that the tubes are stacked one another.

As shown in the drawings, the container 1 has a tube body 3 with an opened end 5. A diameter of the tube body 3 is designed to be reduced as it goes from an upper end 4 where the spouting member 2 is formed to the opened end 5. A container 1 is inserted in a cavity of the container 1. That is, the containers 1 can be stacked one another.

The stacked container 1 are separated one by one by a series of machine and are filled with the contents. Then the lower end 5 is sealed through a thermal sealing process to define seal portion 7.

It is preferable that the cap is closed on the spouting member 2 before the lower end 5 is sealed. The spouting member 2 is opened by a one-touch method or a separated cap is used to close the spouting member.

To prevent vacuum from being generated when stacking and separating the containers, a vacuum-preventing step can be formed on

an inner or outer wall of the tube body. Preferably, since the spouting member has a predetermine length, the front end of the spouting member contacts the rear end of another spouting member to provide a gap between the containers, thereby preventing vacuum from generating between the containers.

INDUSTRIAL APPLICABILITY As described above, since the spouting portion is inclined, it is possible to fully squeeze out the content out of the container.

Furthermore, since the container is tapered, the containers can be stacked in multiple steps, thereby saving the deliver costs.
