Abstract

The present invention provides a squeeze container capable of reducing remaining contents without greatly compressing and deforming the vicinity of a shoulder portion thereof. The present invention relates to a squeeze container for discharging contents by compressing a body portion back and forth from the outside, wherein the body portion has a shape of a polygon or an oval tapered in a left-right direction in plan view, the body portion includes a pair of front-and-back pressing portions that is disposed to face each other so as to flatten the polygonal or the oval in the left-right direction by being compressed back and forth so as to be brought into close contact with each other, and a pair of left-and-right tapered portions connecting the pressing portions to each other, and a pair of front-and-back V-shaped grooves are provided between each of the pressing portions of the body portion and the shoulder portion so as to face each other while being recessed in a central axis direction of the body portion and having a groove bottom formed by an upper bending line extending substantially horizontally.

First claim

The invention claimed is:

1. A squeeze container comprising:
an open cylindrical neck portion;
a shoulder portion extending substantially horizontally from a base end of the neck portion;
a body portion provided below the shoulder portion; and
a bottom portion provided below the body portion,
wherein the body portion is compressed back and forth from outside to discharge contents,
the body portion has a shape of a polygon or an oval tapered in a left-right direction in plan view,
the body portion includes a pair of front-and-back pressing portions that are disposed to face each other so as to flatten the polygon or the oval in the left-right direction by being compressed back and forth, and a pair of left-and-right tapered portions connecting the pressing portions to each other, and
a pair of front-and-back V-shaped grooves are provided between each of the pressing portions of the body portion and the shoulder portion so as to face each other while being recessed in a central axis direction of the body portion and having a groove bottom formed by an upper bending line extending substantially horizontally.

2. The squeeze container according to claim 1 , wherein
the shoulder portion includes a pair of front-and-back main shoulder edges facing a corresponding pair of front-and-back pressing portions and a pair of left-and-right side shoulder edges connecting a corresponding opposite ends of the front-and-back main shoulder edges to each other,
the V-shaped grooves are provided symmetrically front and back between the main shoulder edges of the shoulder portion and a corresponding pressing portions of the body portion,
inclined portions each in a shape tapered downward outside are provided symmetrically left and right between the side shoulder edges of the shoulder portion and a corresponding tapered portions of the body portion,
the inclined portion has a shape tapered from the side shoulder edge toward the end portion of the tapered portion, and
the upper bending line extends to a tapered apex of the inclined portion or to a lower vicinity of the tapered apex.

3. The squeeze container according to claim 1 , wherein
the bottom portion extends substantially horizontally, and
a pair of front-and-back second V-shaped grooves are provided so as to face each other between each of the pressing portions of the body portion and the bottom portion while being recessed in the central axis direction of the body portion and having a groove bottom formed by a lower bending line extending substantially horizontally.

4. The squeeze container according to claim 3 , wherein
the bottom portion includes a pair of front-and-back main bottom edges facing a corresponding pair of front-and-back pressing portions and a pair of left-and-right side bottom edges connecting a corresponding opposite ends of the front-and-back main bottom edges to each other,
the second V-shaped grooves are provided symmetrically front and back between the main bottom edges of the bottom portion and a corresponding pressing portions of the body portion,
second inclined portions each in a shape tapered upward outside are provided symmetrically left and right between the side bottom edges of the bottom portion and a corresponding tapered portions of the body portion,
the second inclined portion has a shape tapered from the side bottom edge toward the end portion of the tapered portion, and
the lower bending line extends to a tapered apex of the second inclined portion or to an upper vicinity of the tapered apex.

5. The squeeze container according to claim 1 , wherein
a leg portion extending downward is provided in the bottom portion.

6. The squeeze container according to claim 1 , wherein
a droplet nozzle is provided in the neck portion.

7. The squeeze container according to claim 1 , wherein
the body portion is configured so as not to be restored after being compressed.

8. The squeeze container according to claim 7 , wherein
the neck portion is provided with a check valve for allowing a flow from inside to outside and blocking a flow from outside to inside.

9. The squeeze container according to claim 7 , wherein
the squeeze container is made of a plastic deformable material.

10. The squeeze container according to claim 1 , wherein
the neck portion includes a cylindrical neck portion main body and a narrowed portion reduced in diameter below the neck portion main body.

11. The squeeze container according to claim 1 , wherein
an internal space is filled with medicine by 15 to 85% of a full volume.
