[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deformed spout plug which is attached to the neck of an extrusion container and pushes out viscous contents into a predetermined shape, and more specifically, to improve the hermeticity of the container when the cap is attached after use. The present invention relates to a modified outlet spout for an extrusion container that is improved.

[0002]

[Prior art]

 Conventionally, extruded containers are filled with foods such as mustard paste, mayonnaise, cream, and chocolate, which have a certain degree of viscosity, and toothpaste, hairdressing treatments, and other treatments. Due to the trend, there is a growing demand for pushing the contents into not only a circular cross-sectional shape but also an odd shape such as an ellipse or a polygon when used. For this reason, many devices have been devised regarding the special-purpose pouring to push out into a predetermined shape by devising the pouring port of the extruding container, such as Japanese Utility Model Laid-Open No. 62-22942 and Japanese Utility Model Laid-Open No. 1-126948. There is.

[0003]

[Problems to be solved by the device]

 However, in many of the inventions that have been filed in the past, even if the cap is mounted after use, even if the cap is attached after use, the cap has a predetermined cross-sectional shape up to the tip of the spout of the extrusion container. Since it was not possible to fit the inner ring of (1) to the inner surface of the spout closely, it was difficult to obtain a sufficiently sealed state of the container. According to the present invention, when a cap is attached to the spout of the extruding container after use, the inner surface of the spout of the extruding container and the inner ring of the cap are closely fitted to each other so that a sufficient sealed state of the extruding container can be obtained. A modified outlet spout for a container is provided.

[0004]

[Means for Solving the Problems]

 As shown in FIG. 1 and FIG. 2, the present invention is a modified spout plug that is attached to the neck portion (311) of an extruding container (300) and pushes out viscous contents into a different shape. ) Has a circular horizontal cross-section at the tip of the spout (111), and a fitting portion (113) that fits with the inner ring (122) of the cap (120) on the inner surface of the spout tip. A deformed spout plug for an extrusion container characterized in that a deformed shape forming portion (112) having a predetermined horizontal cross-sectional shape smaller than a circular horizontal cross-section at the tip of the spout is provided below the fitting portion. It is (100).

The above-mentioned extrusion container is a laminated tube made of a laminated material in which paper, aluminum foil, plastic film, etc. are laminated, a single-layer or multi-layer plastic tube or bottle produced by an extrusion molding method, a blow molding method, or the like. It has a flexible body.

The fitting portion between the inner surface of the spout body tip and the inner ring of the cap may be line contact or surface contact.

The deformed shape forming portion is preferably formed at a position as close as possible to the tip of the spout of the spout. Further, the horizontal cross-sectional shape of the irregular shape forming portion can be selected from various arbitrary irregular shapes such as an elliptical shape, a rectangular shape, a triangular shape, a star shape, and a Y shape.

[0008] A method for attaching the irregular shape outlet plug to the neck of the extrusion container is generally performed by screwing or biting.

[0009]

[Action]

 The extrusion container of the present invention, which has a modified outlet plug for an extrusion container attached to the neck, has a cap attached to the outlet after use, as shown in FIG. The outer peripheral surface of the formed annular inner ring (122) is line-contacted or surface-contacted with the circular inner surface of the spout (111) tip provided above the irregular shape forming portion (112) of the spout. Contact and mate to completely seal the container. Therefore, the viscous contents filled in the container do not leak.

The size of the horizontal cross-sectional shape of the irregular shape forming portion is smaller than the circular horizontal cross-sectional shape of the tip of the spout of the spout, and the tip of the spout is extremely close to the tip of the irregular shape forming portion. The viscous contents formed in the irregular shape forming portion do not lose their shape before being poured from the tip of the spout.

A stopper body (110) having a joint portion (116) and an inner ring (122) fitted to the tip of the outlet of the stopper body on the lower surface of the top plate (121) are connected by a snap hinge (130). A modified outlet plug (100) for an extrusion container of the present example, which is composed of a cap (120), was manufactured by injection molding using polypropylene.

As shown in FIG. 3B, the spout body (110) of the spout body (110) according to the present invention has a circular horizontal cross-section at the tip of the spout and a cap on the inner surface. It has a fitting part (113) that fits with the inner ring, and below this fitting part, the horizontal cross-sectional shape is smaller than the horizontal cross-sectional shape of the tip of the spout, and the wound-shaped variant shown in Fig. 3 (a). It has a shape forming part (112).

Next, the neck portion is made of an inorganic material and polyethylene, and the laminated material of the body portion is a laminated material of polyethylene layer / paper layer / ethylene methacrylic acid copolymer layer / aluminum foil layer / ethylene methacrylic acid copolymer layer / polyethylene layer structure. A laminated tube consisting of the above was prepared, and the deformed spout plug for extrusion container of the present example was fitted to the neck part and fitted, and a toothpaste was filled from the open bottom part, and the bottom part was heat-sealed. And sealed.

Next, in order to evaluate the irregular-shaped outlet / outlet plug for the extrusion container of the present example, the cap of the produced plug of the laminated tube containing toothpaste was removed and pushed out onto a toothbrush. As shown in Fig. 6 (a), toothpaste is discharged in a wound shape, and therefore has better adhesion to the toothbrush than the conventional cylindrical discharge shown in Fig. 6 (b). there were. After use, a cap was attached to the variant outlet spout for an extrusion container of the present example, the body was pressurized and left standing upside down for 24 hours. However, the contents of the tip of the outlet did not leak. Did not occur.
