Abstract

In a packaging container in which a funnel-shaped spout is attached to a container body, positioning of a portion to which the funnel-shaped spout is attached is facilitated, and manufacturing costs are reduced. The packaging container includes: a container body having a body portion in which an engaging wall is provided, and a bottom portion provided at a first end of the body portion; a funnel part having a funnel shape within the body portion, and an wide opening end thereof is restricted from moving toward at least the first end by the engaging wall; and a sealing lid sealed to an opening portion which serves as the second end of the body portion while being in contact with a narrow opening end of the funnel part to seal the container body.

First claim

What is claimed is:

1. A packaging container comprising:
(A) a container body comprising a body portion, a bottom portion at a first end of the body portion and an opening at a second end of portion, the body portion has a tapered shape, in which a diameter is gradually increasing from the first end to the second end of the body portion, the body portion comprises an engaging groove extending outwards from an inner volume of the container body;
(B) a funnel part having a funnel shape, the funnel part has an narrow opening end and a wide opening end, the funnel part is inserted into the inner volume of the container body, and the wide opening end of the funnel part is restricted from moving toward the first end of the body portion by the engaging groove; and
(C) a sealing lid sealed to the opening portion of the container body while being in contact with the narrow opening end of the funnel part to seal the container body, wherein the funnel part comprises an engaging portion at the wide opening end thereof, the engaging portion comprises a projection extending outwards from an inner volume of the funnel part, the projection of the engaging portion is engaged with the engaging groove to further restrict the wide opening end of the funnel part from moving toward the second end of the body portion.

2. The packaging container of claim 1 , wherein the engaging portion comprises a tapered portion, which is surface contact with the tapered shape of the body portion when the projection of the engaging portion is engaged with the engaging groove of the body portion.

3. The packaging container of claim 1 , wherein at least a part of the engaging portion is welded to an inner surface of the body portion.

4. A method of manufacturing the packaging container of claim 3 , the method comprising:
a step of heating the engaging groove and the engaging portion in advance;
a step of inserting the funnel part from the wide opening side thereof into the inner volume of the container body through the opening portion of the body portion; and
a step of engaging and adhering the projection of the engaging portion to the engaging groove for fixing.

5. A method of manufacturing the packaging container of claim 3 , the method comprising:
a step of inserting the funnel part from the wide opening side thereof into the body container through the opening portion of the body portion;
a step of engaging the projection of the engaging portion with the engaging groove; and
a step of heating and adhering the engaging portion in a state of being engaged with the engaging groove for fixing.

6. The packaging container of claim 1 , wherein the sealing lid includes an easy peel film on an inner surface of the packaging container.
