When described in detail based on the accompanying drawings of the present invention as follows.

1 to 4 show a first preferred embodiment of the present invention.

In principle, the container 1 of the present invention is made of a synthetic resin and an injection molding method.

This will be described with reference to FIG. 1.

The container 1 is configured such that the main body 100 accommodates the contents, and a stopper 200 for opening and closing the main body 100 above the main body 100 borders the horizontal fold line 201. It will be molded injection molding integrally.

In addition, the upper end of the plug portion 200 has a first adhesive portion 203 extending in all directions on the boundary of the adhesive portion first boundary fold line 202, and faces an arbitrary portion of the first adhesive portion 203. A pair of 2nd bonding part 204 is comprised so that a 2nd boundary fold line 205 may be a boundary.

In addition, between the horizontal folding line 201 and the first bonding portion 203 between the pair of second bonding portion 204 is formed at the center of the first bonding portion 203 at both ends of the horizontal folding line 201. An inward fold line 207 formed to the auxiliary fold line 206 is formed, starting from both ends of the lower end of the inward fold line 207 to the next opening portion of the opening guide auxiliary fold line 208. Opening guide fold line 209 of the mold is to be formed.

On the other hand, in the rectangular container 1, each corner portion is composed of a vertical fold line (VL).

The use state of the present invention as described above is as follows.

In the state as shown in FIG. 1, as a series of mechanical devices, when the auxiliary fold line 206 is turned inward and the first adhesive part 203 is brought into close contact with each other, the stopper 200 as shown in FIG. 2. In the above state, the first and second adhesive parts 203 and 204 are sealed by ultrasonic waves (high frequency or thermal bonding, adhesive coating) or the like.

At this time, the synthetic resin stopper portion 200 can be folded in the shape of each fold (each horizontal fold line 201, the first boundary fold line 202, the adhesive line second boundary fold line 205, 205, auxiliary) This is because the fold line 206 and the inward fold line 207 are formed.

Each of the fold line is to form a fold line to the outside or inside a little hollow shape.

In addition, for easy opening, the inner wall surface of the first adhesive portion 203 or the second adhesive portion 204 can be sealed by applying an adhesive such as a hot melt.

In the opening of the present invention described above, when the vertical folding line (VL) in the direction of the opening guide folding line 209 in the state shown in Figure 2 spread outwards as shown in Figure 3, the outflow hole is formed.

And when re-storage after drinking, when the inward folding line 207 is pushed inward to the original state is folded while maintaining hermeticity.

For reference, an inner wall surface of the second adhesive portion 204 may be formed to protrude more than the first adhesive portion 203 to reinforce the sealing property.

4 shows a state in which the container 1 of the present invention described above is stacked in multiple stages.

As another embodiment, as shown in FIG. 5, the container 1 of the present invention may be formed with an opening and closing stopper C, which may be integrally formed or separately adhered, and the shape thereof may be as shown in FIG. A screw (C) or a stopper (C) having a wide variety of shapes, such as a locking jaw method may be applied as shown in FIG. 6.

Alternatively, as shown in FIG. 7, a one-touch stopper C may be applied or an opening may be formed by adhering an adhesive tape to an upper surface having an outlet hole.

As shown in FIG. 8, a method of forming a cutting line 210 for forming a straw or forming a cutting film, and the cutting film is removed by a pulling ring.

For your reference,

9 shows that the upper end portion "A" is configured to be wider than the lower end portion "B" in order to stack the container 1 of the present invention in multiple stages, and as shown by the dotted line, the inner wall portion of the main body 100 has an arbitrary size. The vacuum barrier 101 is formed.

As another embodiment (Figs. 10 and 11), the container 1 of the present invention described above is the upper end (the stopper 200) is narrow and the lower end (the body 100) to widen the stopper 200 when stacked in multiple stages ) Is to be inserted into the inside, in this case it is preferable to fill the contents through the lower end of the body 100, after filling is to separate the foil or cover 102 by ultrasonic or the like method.

11 is a reference diagram showing a state in which the container 1 is stacked in multiple stages.

As another embodiment (FIGS. 12 to 15), the container 1 may form a fold line L extending long below the auxiliary fold line 206 so that it can be folded and disposed of after use. have.

The pair of fold lines (L) is composed of a fold line (L ₁ ) is connected to the lower side, each side of the fold line (L) in the inward of the divided type started at the bottom of the vertical fold line (VL) Tangent line L ₂ is formed.

In addition, the auxiliary fold line (L ₃ ) is formed at the lower end of the main body 100 for the smooth operation of the fold line (L, L ₁ , L ₂ ).

The container 1 is sealed as shown in FIG. 13, and when used (drinking), the container 1 is discarded as shown in FIG. 14.

FIG. 15 shows an example in which the container 1 is configured to be slightly recessed in the folded portion so that the container 1 can be easily folded.

The present invention as described above can be vacuum molding or vacuum forming.

And the container 1 of the present invention, as well as the rectangular shape, it is possible to apply the idea of the present invention, such as elliptical within the range that the stopper 200 can be folded.

In another embodiment (FIG. 16), the above-described foldable or stacked container 1 of the present invention has a stopper C having a structure capable of sucking or sucking the contents of the container 1 and transferring the contents to another container. ) Is formed.

As an example of the above structure, as shown, the discharge table (C 1) having a predetermined length into the stopper (C) is assembled, the discharge table (C 1) is a predetermined depth inside the container (1) Connected to.

And the discharge zone (C 1) is a side outlet hole (C 2) (side discharge hole) is formed in the downward direction of the stopper (C), the lower side of the side discharge hole (C 2) the ring projection (C) 3) is formed.

In the use of the present invention as described above, when the cover (C 4) is opened, the discharge table (C 1) comes up, and when the ring protrusion (C 3) touches the bottom of the stopper (C), the discharge table (C 1) is It will no longer be upgraded and will stop.

At this time, when the mouth is sucked on the discharge (C 1), the contents are sucked out by the discharge (C 1) formed to the inside of the container (1).

In the above process, the side outlet hole C 2 is in a blocked state, and an air inlet is formed next to the side outlet hole C 2, and the air inlet can be introduced into the container 1. It is.

In addition, if the container 10 is leaned backward after lowering the discharge zone (C 1), the side lead-out hole (C 2) is opened, and the contents are passed through the side outlet hole (C 2).

And the discharge zone (C 1) is a variety of things can be applied.

17 shows another structure of the present invention.

Since the container is made of synthetic resin, there is no fear of breakage, as well as the ability to check the contents can be processed in a transparent material.

In addition, the bottom portion of the container is sealed, there is an advantage that can be easily applied in a small workplace.
