Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a creamy substance discharge container. In addition, in the present invention, the term "creamy material" is used to mean liquid as well as cream.

"Prior Art" From a cylinder mounted on a container body, an operating member having a push-down head fitted with a nozzle fitted to the upper end of the stem is projected upwardly, and the liquid inside the container is moved to the cylinder by the vertical movement of the operating member relative to the container body. The pump-type liquid ejection container provided so as to suck up the liquid in the cylinder and eject the liquid in the cylinder from the nozzle of the operating member is attached to the operating member because the operating member interferes during transportation and the packaging becomes bulky. It is known that the upper part of the actuating member is detachably screwed onto the inner surface of the holding cylinder that is fixed to the upper end of the cylinder by pushing down against the force.

Then, in order to use the container for discharging the content having poor fluidity, a flexible bag filled with a creamy substance inside is stored in the container body via a bag mounting cylinder, The applicant previously proposed a creamy substance discharge container in which the creamy substance in the bag is discharged by the above-mentioned pumping (“the creamy substance discharge container filed by the applicant on June 14, 1988”). See "Container").

"Problems to be solved by the invention" However, in the above-mentioned conventional creamy substance discharge container, since the holding tube is linked to the upper end of the cylinder in a non-rotatable manner, the actuating member is not attached when assembled in a factory or the like. When the machine is fastened to the holding cylinder, it may be over-tightened due to a mechanical malfunction.In such a case, if the operating member is forcibly unscrewed when using the container, the mounting member that makes frictional contact with the cylinder will rotate in the specified rotation direction. There is a disadvantage that the screw cannot be unscrewed because it is rotated together with the holding cylinder with respect to the container body by receiving the force.

Therefore, an object of the present invention is to provide a creamy product discharge container in which rotation of a mounting member in a predetermined direction can be prevented and an operating member can be reliably unscrewed from a holding cylinder.

[Means for Solving the Problems] In order to achieve the above object, the creamy substance discharge container according to the present invention comprises a container main body 1 for erecting a mouth / neck portion 4, a top surface of the mouth / neck portion, and an upper end of a tubular portion 8. The first outward flange 9 attached to the above is placed and the tubular portion is hung down into the container body, and the upper half of the tubular portion is used as the large inner diameter portion 8a and the outside air suction hole 10 is bored in the large inner diameter portion. And a flexible bag 11 in which the inside of the container is filled with a creamy substance and a bag mouth edge portion 12 is attached to the lower outer surface of the tubular portion. A ring-shaped top plate 14 is placed on the upper surface of the first outward flange 9, and an outer peripheral wall 15b is fitted from the inner peripheral edge of the ring-shaped top plate to the inner peripheral wall 15a and from the outer peripheral edge to the outer surface of the upper end of the mouth and neck.
And the lower half of the cylinder 19 is inserted into the bag 11 by inserting the anti-rotation member 13 and the inside of the bag mounting cylinder into which the second half is attached.
The outward flange 20 is placed on the upper surface of the ring-shaped top plate 14, and the stem 23 of the operating member 22 in which the pressing head 21 with the nozzle is fitted at the upper end is pushed down into the cylinder against the bias. A pump-type creamy substance dispenser 18 in which an upper part of the operating member and a holding cylinder 24 fixed to the upper end of the cylinder are screwed together in the depressed state, and a peripheral wall 28 on the lower part of the mouth / neck part 4 and the outer peripheral wall 15b. The first outward flange 9, the ring-shaped top plate 14 and the second outward flange 20 by the inward flange 29 attached to the upper end of the peripheral wall and the mouth neck top surface.
And a mounting member 27 sandwiching the holding member 27, and a first engaging portion 6 and a second engaging portion 16 for preventing rotation are attached to the facing surfaces of the mouth / neck portion 4 and the outer peripheral wall 15b of the rotation preventing member. It is characterized in that a third engagement portion 17 and a fourth engagement portion 25 for preventing rotation are attached to the opposing surfaces of the inner peripheral wall 15a of the rotation preventing member and the cylinder 19.

"Operation" For example, when the actuating member 22 is rotated in a direction to be unscrewed with respect to the holding cylinder 24 after removing the cap 30 from the state of FIG. 1, the holding cylinder is the cylinder 19 and the cylinder is the rotation stopping member 13
In addition, since the anti-rotation member is non-rotatably linked to the container mouth / neck portion 4, no force acts in the rotation direction on the mounting member 27, and even if the actuating member is over-tightened, A sufficient reaction force can be exerted on the holding cylinder, and the operating member can be reliably screwed out.

[Example] An example of the creamy product discharge container according to the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, 1 is a container body, and a body portion 2
The mouth and neck 4 is erected from the upper end via the shoulder 3.

As a result, an outside air suction hole 10 is formed in the large inner diameter portion 8a.

Reference numeral 11 denotes a flexible bag, which is housed in the container body 1 described above and filled with a creamy substance inside, and at the edge of the bag mouth.
12 is made of a film which is adhered to the outer surface of the lower portion of the cylindrical portion 8 by ultrasonic welding or the like.

13 is a rotation preventing member, which is the first outward flange 9 described above.
The ring-shaped top plate 14 is placed on the upper surface, the inner peripheral wall 15a is formed from the inner peripheral edge of the ring-shaped top plate 14, and the mouth / neck portion 4 is formed from the outer peripheral edge.
An outer peripheral wall 15b fitted to the outer surface of the small outer diameter portion 5 is vertically provided. On the inner surface of the outer peripheral wall 15b, the tooth-shaped second engaging portion 1 that non-rotatably engages (engages) with the above-described first engaging portions 6,6.

Each is engraved.

Reference numeral 18 is a creamy substance ejector, which is the above-mentioned rotation preventing member 13
Also, the lower half of the cylinder 19 is inserted into the bag 11 by inserting it into the bag mounting cylinder 7, and the second outward flange 20 attached to the upper part of the cylinder 19 is placed on the upper surface of the ring-shaped top plate 14 described above. In addition, the stem 23 of the actuating member 22 into which the push-down head 21 with a nozzle is fitted at the upper end is pushed into the cylinder 19 against the bias, and the upper part of the actuating member 22 and the upper end of the cylinder 19 are pushed in the pushed state. It is of a pump type in which a holding cylinder 24 fixed to the above is screwed. A fourth engaging portion 25 composed of a plurality of vertical ribs is attached to the outer surface of the cylinder 19 immediately below the second outward flange 20, and the fourth engaging portion 25 cannot be rotated to the third engaging portion 17 described above. Is engaged with.
