Kind Code:
B2
Abstract:
PURPOSE: To provide an excellent pump container in which a pump is attached to a laminated bottle having a peelable internal layer, when a liquid is discharged, the internal layer peels off so as to reduce the capacity, formation by a satisfactory yield method is ensured, and the internal layer is prevented from peeling off.
CONSTITUTION: A recess is formed in a part of the neck 7 of the mouth of a bottle, thereby making a ringlike projection 8 sticking in the neck of the mouth, and the internal surface of the projection 8 is pressed firmly and fixed to the external surface of the sucking part of an attached pump 2, which is inside the bottle, so as to seal in a liquid tightly. In addition to the structure, a downward level-difference part 21 is made in the specific position of the external surface of the sucking part of the pump inside the bottle, and the lower surface of the level-difference part 21 is pressed firmly and fixed to the upper surface of the ringlike projection 8.
