- a container body blow-molded into a laminated bottomed cylindrical shape, and having a bottom seal portion, which is a parison cutout portion, on the lower surface of the bottom plate wall; a cylindrical wall; and a container wall formed continuously with the cylindrical wall.
- a base cap attached to the bottom of the container body, wherein the container body includes a first engagement portion on a bottom side surface, and the base cup includes a cylinder.
- a second engaging portion engaged with the first engaging portion is provided on the inner surface of the wall, and an air flow opening for introducing air and a pressing means abutting against the bottom of the container body are provided.
- the pressing means comes into contact with the bottom, and the slit is opened in the outer layer of the bottom seal portion.
- the pressing means comes into contact with the bottom and opens the slit in the outer layer of the bottom seal.
- a slit can be easily and reliably formed as an air inlet.
- the pressing means is provided on the inner surface of the bottom wall of the base cup so as to stand upright toward the lower surface of the bottom plate wall.
- the protrusion pushes up the bottom plate wall to open a slit in the outer layer of the bottom seal, so that the base cup is engaged and the bottom plate of the container body is engaged.
- the projecting piece presses the lower surface of the wall
- the base cup can be securely fixed to the container body by engagement, and the pressing force by the projecting piece acts on the lower surface of the bottom plate wall, which is thicker than the body. Therefore, the pressing force acts without being dispersed, and the slit for deforming and curving the bottom seal portion by the projection and introducing the outside air between the outer layer and the inner layer at the bottom of the container body can be reliably and easily opened.
- the projecting piece in the pouring container according to the second aspect, is erected at a position deviated from the center of the bottom wall. When this is done, the projecting piece will make the bottom plate wall surface
- the slit can be reliably opened by moving and pressing in a circular shape.
- the protruding piece since the protruding piece is erected at the center of the bottom wall of the base cup, the protruding piece directly presses the center of the cutout portion, thereby ensuring the The slit can be opened.
- the air circulation port is provided at the center of the bottom wall of the base forcep, so that the outside air is smoothly interposed between the inner and outer layers.
- the pressing means is a pressing portion provided inside the base cup and pressing the bottom plate wall from the side, When the cup was attached to the bottom of the container body, the slit was opened in the outer layer of the bottom seal by the pressure of the pinching part. Therefore, according to the invention as set forth in claim 6, since the pressing portion presses the bottom plate wall from the side with the engagement of the base cup, the bottom plate wall is gradually pressed while rotating the base cup.
- the holding portion protrudes from the inner surface of the cylindrical wall, and has a distance smaller than an outer diameter of the bottom plate wall, at least a pair of protrusions. Since the bottom plate wall is sandwiched between the protrusions and pressed from the side, a slit can be reliably formed in the bottom seal portion.
- the bottom plate wall is formed as an ellipse or an oval with the major axis in the direction of the parting line, and the interval between the clamping parts is shorter than the major diameter.
- the portion is pinched by the pinching portion of the base cup and pressed and deformed to form a slit in the bottom seal portion.
- the clamping portion is formed as an ellipse or an ellipse having a longer major axis and a shorter minor axis than the outer diameter or the major diameter of the bottom plate wall.
- the holding portion is provided inside the cylindrical wall at a predetermined distance from the cylindrical wall. Since it is formed by the pressing wall standing upright from the wall, the reaction force generated by the pressing of the bottom plate wall is not transmitted from the pinching part to the female screw part, the screw connection at the screw part is loosened, and the airtightness is impaired It is possible to provide a dispensing container that does not need to be discharged.
- the clamping portion is formed in a tapered shape in which the interval between the lower portion and the upper portion is smaller. As the base force is advanced, the pressing force generated on the bottom plate wall is increased, and the slit can be reliably formed by the engagement of the base cup.
- the container main body is formed so as to be squeezable, and the backflow of the contents into the mouthpiece portion and the outside air
- the first check valve for preventing the inflow of air is provided in the mouthpiece
- the second check valve for preventing the air from flowing out of the base cup is provided in the air circulation port.
- the contents of the inner layer can be poured out without squeezing, and the slit can be easily formed in the cutout portion even in a squeeze container having a relatively flexible body.
