DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view of an embodiment of the container according to the present invention,
FIG. 2 is a sectional view showing a method of bonding the bottom 5 to the container body 1.

The container body 1 is, for example, a hollow, substantially cylindrical body made of synthetic resin or the like with a polyvinyl alcohol layer interposed between front and back polyethylene, and has a spout 2 with a narrow mouth at one end and a spout 2 at the other end. The bottom 5 is attached to the wide opening. The container body 1 is obtained by means such as blow molding. Around the outer wall slightly below the container body 1, a stopper 8 having a substantially vertical cross-sectional V-shape and the V-shaped tip of which protrudes slightly downward is formed. The container body 1 gradually increases in diameter toward the opening 3, and further opens in a trumpet shape from the position of the stopper 8, and a flange 4 is formed on the periphery. Bottom 5
Has a substantially conical bottom surface.

The bottom portion 5 is formed of a member different from the container body 1 in this embodiment. It is made of the same material as the container body 1 and has a size corresponding to the bottom opening 3 of the container body 1 and is adhered to the opening 3 of the container body 1 such that the conical top of the bottom 5 is inside. . By forming the bottom 5 in a conical shape, when the container body 1 is pinched and the contents near the bottom are squeezed out, the bottom is bent so that it can be easily squeezed out.

The bonding between the container body 1 and the bottom 5 is performed, for example, as follows (see FIG. 2). First, after the spout 2 of the container body 1 is closed using the cap 11 or the like, the contents are filled through the wide opening 3 with the opening side of the container body 1 facing upward. Since the container body 1 and the bottom 5 are composed of separate members and the contents can be filled not through the narrow spout 2 but through the opening at the bottom of the wide mouth, the filling operation is extremely easy and reliable. It is suitable for filling a paste-like food or the like as a content. After filling the contents, the bottom 5 is bonded to the opening 3 of the container body 1 as shown in FIG. Reference numeral 31 denotes a content.

The cap 11 attached to the spout 2 is
For example, when using a synthetic resin in which the polyvinyl alcohol layer is interposed between the front and back polyethylene as described above, the container body 1 is made of polypropylene,
It is preferable to use a material having a smaller expansion coefficient than the material of the container body 1. If the cap 11 and the container main body 1 are made of a material having the same expansion coefficient, for example, when the contents are filled and the boil sterilization is performed, the contents may ooze from the spout. When the material is formed of a material having a smaller expansion coefficient than the material, the spout 2 of the container body 1 is closed by the cap 11 during sterilization of the boil due to the difference in the coefficient of thermal expansion, so that leakage of the contents is prevented. In addition, it is not necessary to attach a sealing member to the spout 2 before attaching the cap 11, so that the manufacturing process of the product can be simplified. When the cap 11 is applied without attaching the sealing member to the spout 2 as described above, the contents are exposed from the spout as soon as the cap 11 is removed. It is important to prevent the cap from being opened.

As shown in FIG. 2, the cap 11 has a fitting portion 12 which fits inside the tip 2a of the spout 2 and a female screw 13 for attaching to the spout 2 formed on the inner periphery. The connecting portion 14 has a grip portion 15 having a larger diameter. In addition to being screwed to the spout 2 by the connecting portion 14, the fitting portion 12 is fitted to the spout tip 2a,
Hermeticity is assured. Further, the spout tip 2a
The gap between the fitting portion 12 and the connecting portion 14, which is a portion into which the fluid enters, is formed to be slightly smaller than the thickness of the spout tip 2a, and is pressed against the spout tip 2a from outside and / or inside. If it is attached in a state, the sealing performance at the spout can be further enhanced, and leakage of the contents from the portion can be completely prevented.

The bonding between the container body 1 and the bottom 5 can be performed by heat sealing or the like. Since the container body 1 is open in a trumpet shape from the position of the stopper toward the opening 3 and the flange 4 is formed on the peripheral edge, when bonding such as heat sealing, as shown in FIG. Are easy to set without hitting the pedestal 21 and heat sealing is easy. A step portion 6 is provided on the outer periphery of the bottom portion 5 so as to correspond to the flange portion 4, and the step portion 6 and the flange portion 4 are matched with each other and bonded by a hot plate to obtain a product. In addition, since the peripheral wall surface of the container main body 1 is gradually opened toward the bottom thereof, a large number of other container main bodies 1 can be sequentially fitted into the container main body 1 and stacked. Space saving during storage and transportation can be achieved,
It leads to cost reduction. It should be noted that the stopper has an effect that serves as a filling guide when filling the contents.

Finally, a shrink wrap 17 is provided as an exterior and distributed as a final product. As shown in FIG. 1, the shrink wrap 17 is securely locked by the stopper 8 formed in the container body. Because it is fixed, it does not come off. Particularly, in this embodiment, the container main body 1 has a gradually increasing diameter toward the opening 3 and further opens in a trumpet shape from the position of the stopper 8. The effect of preventing disengagement is even greater.

Since the obtained container has a flat bottom, it can be displayed or used in an upright state, and it has an extremely wide shape near the bottom. Can stand in a stable state. Also, the filling amount of the contents can be increased.

[0017]

As described above, according to the container of the present invention, not only can it be displayed and used in an upright state, but also the cap and the container body can be provided on the wall surface of the container body. A protruding stopper for preventing the shrink wrapping, which is integrally formed with the shrink wrapping, is formed continuously or intermittently, so that the shrink wrapping is securely locked and fixed by the stopper.
