Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an extrusion container that is frequently used to store toothpaste, toothpaste, cosmetic cream, and other viscous substances.

[Prior Art] Conventionally, as this type of extrusion container, a tube container formed by multi-layer blow molding of plastic, or a sheet in which plastic, paper, aluminum foil, etc. are appropriately laminated is formed into a tubular shape,
There is one in which a lid body made of a plastic molded product and having an outlet is welded to this opening.

[Problems to be solved by the invention] In the above-mentioned conventional extrusion container, it is not easy to push out the contents properly until the end, and the tube container is rolled up from the bottom or rolled up, or the container body is pinched with fingers. It is common practice to squeeze the ironed contents.

An extruding container improved in view of such a conventional situation is disclosed in, for example, Japanese Utility Model Publication No. 56-54190, which finally extrudes the contents almost completely by folding the container body properly. However, since the bottom part is folded toward the outlet side, the contents may remain in the folded part, but in order to prevent it from remaining there, work to expel the contents near the bottom beforehand. Is troublesome.

[Means for Solving the Problem] The present invention has been made to solve the technical problem of such a conventional extrusion container, and as a means for solving the problem, a lid having a rectangular tube-shaped container body having an outlet is provided. A body is attached, and the bottom portion of the container body is formed in a roof shape, and the opposite side surface of the roof runs from the sealing portion at its tip in a direction perpendicular to the sealing portion, and further, the container body continues. The gist of the present invention is to provide a fold line that passes through the side surfaces of the fold line and reaches the lid body.

[Operation] Since the present invention is configured as described above, if the bottom of the container body is properly folded along the fold line, the contents near the bottom can be almost completely and easily ejected forward. Can be done, and the work is extremely easy.

Embodiment Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiment.

In FIG. 1, reference numeral 1 denotes a container body having a rectangular cross section, which is formed from a sheet-like blank mainly made of paper, and a lid 2 having an outlet 2a formed of plastic is welded to the upper part thereof, The bottom is shaped like a milk carton roof (Gobel top).

As shown in FIG. 2, the container body 1 has four side plates 11 to 14 arranged side by side and four bottom plates 15 to 18 connected to the lower edges of these side plates. Sealing piece 15 on the bottom edge of the bottom plate
a to 18a are respectively provided in series, the attachment pieces 14a are provided in series at the side edges of the side plate 14, and the attachment pieces 1a for attaching the lid body 2 are provided at the upper edge of the container body 1. There is.

In addition, the container body 1 includes the sealing piece from the upper edge of the side plate 12.
A center fold line P reaching the lower edge of 16a is provided, and this side plate 12
Also on the side plate 14 side that is in a facing relationship with the above-mentioned sealing piece from its upper edge.
A center fold line Q reaching the lower edge of 18 is provided, and a horizontal fold line R connecting the center fold lines P and Q in a perpendicular direction is provided on the upper side of the container body 1. Further, the side plate 12 is provided with a mountain fold line S having an apex at the intersection of the central fold line P and the horizontal fold line R, and similarly, a mountain fold line T is also provided on the side plate 14 side.

On the other hand, the bottom plate 16 is also provided with a chevron fold line U having an apex at the intersection of the lower edge of the bottom plate 16 and the central fold line P in the same direction as the chevron fold line S.
The chevron fold line V is also provided in 18 in the same direction as the chevron fold line Q.

The container body 1 configured in this manner is formed into a rectangular tube shape as shown in FIG. 1, and the peripheral portion of the lid body 2 is welded to the upper opening side of the container body 1 from the opening side of the bottom portion. After filling with an object (not shown), the extrusion container 3 can be formed by sealing the bottom of the product with a roof mold such as a Gobel top. At this time, the central folding lines P and Q run from the sealing portion 3a at the bottom of the container to the opposite side surfaces 16 and 18 of the roof,
Following this, the positions that reach the lid body 2 through the opposite side surfaces 12 and 14 of the container body 1 are respectively occupied.

The extrusion container 3 according to the present invention is configured as described above,
When the contents decrease due to use, as shown in FIG. 3, the center fold lines P and Q are pushed inward to crush the bottom portion of the container body 1, and the bottom portion can be squeezed by pinching with fingers. Can be properly folded into a flat state, which allows almost all of the contents near the bottom to be pushed forward, without the contents remaining near the bottom.

After this, when the contents approach the end, the container body 1 is properly folded while sequentially squeezing from the bottom using the central fold lines P and Q, and when the final stage is finally reached, the chevron fold line S, When the lid body 2 is properly folded over the container body 1 by using T and the lateral folding line R so that the outlet 2a thereof faces upward, as shown in FIG. The contents can be pushed out from the outlet 2a without leaving any residue.

When the lid 2 is welded, a mounting groove 2b is provided around the lid 2 as shown in FIG. 5, and if the mounting piece 1a of the container body 1 is fitted into the mounting groove, the cut surface is cut. 1b is not exposed, which protects the contents (not shown) and
The attachment portion of the lid 2 is also protected, which is convenient. If such a mounting groove is not used, a notch is formed at the tip of the mounting piece 1a of the container body 1 as shown in FIG. Cutting surface 1b at the tip
Is not exposed, and the contents and the lid mounting portion are protected as described above.

Also, when the mounting piece 14a of the side plate 14 is welded to the inner surface of the side edge portion of the side plate 11, as shown in FIG.
If the tip of a is rolled in and attached, the notch surface and the cut surface can be prevented from being exposed.

[Effects of the Invention] As described above, according to the present invention, the bottom of the extruding container is formed in a so-called Gobel top type, and continuous fold lines from the sealing portion to the lid at the tip of the container are formed on both sides. Since it is provided on the bottom, it can be folded properly without folding back the bottom, it prevents contents from remaining on the bottom, and it has excellent practicality such as pushing out the contents easily. .
