[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a replacement container for a vertical head type pump.

[0002]

2. Description of the Related Art A large number of dispensing containers with a vertical head pump have been proposed and are well known.
No. 3 is an example of them, the container described in the publication is formed of a container body for filling the stored material and a vertical pump,
The vertical pump vertically suspends a cylinder via an inward flange-like wall from an upper inner surface of a mounting cylinder portion screwed to an outer surface of a container body neck and neck portion, and a cylindrical piston is provided from the inside of the cylinder to a lower end of a stem. When the actuating member having a press-down head with a nozzle at the upper end of the stem is urged upward to stand up and the actuating member is depressed via the press-down head, the liquid in the cylinder is pressurized and pressurized from the nozzle. When the liquid is discharged and the press-down head is released, the cylindrical piston rises to make the pressure in the cylinder negative, and the liquid stored in the container is sucked into the cylinder.

[Problems to be solved by the invention] Recently, as waste disposal has become a social problem, there is a demand for recycling of various resources and reduction of non-combustible waste, and synthetic resin products are also covered. . In a dispensing container with a vertical head pump,
In order to respond to such a request, for example, a type in which a vertical pump is replaced with a replacement container body and formed so that it can be used continuously has been proposed. In the case of a creamy substance, since the creamy substance is attached to the inner wall surface of the container at the time of disposal and it is troublesome to wash it, it is eventually disposed of as waste without being reused. It was a fact.

According to the present invention, the outer container body is separated and discarded for reuse by forming the inner container body for filling the stored contents in the rigid outer container body and forming the inner container body so that the inner container body can be easily taken out. Provided to be able to.

[0005]

Means for Solving the Problems A rigid outer container body 1 in which a fitting tube 8 is erected from the upper end of a body portion 9 via a shoulder portion, and is fitted to the outer surface of the fitting tube 8 of the outer container body so as to be able to be forcibly extracted. The mouth and neck 4 is erected from the upper end of the combined outer cylinder 11 via the inward flange-like wall 7 and the cylinder wall of the mouth and neck is formed to extend downward, thereby forming a lower portion of the extension forming portion 4a. An inner container body 3 for accommodating a cream-like material in which the inner surface of the mouth portion of the synthetic resin sheet bag portion 5 is air-tightly connected, and a vertical wall extending from the peripheral edge of the top wall closing the upper surface of the mouth and neck portion 4 of the rigid cylindrical body 2 The peripheral wall thus formed was formed by a cap 6 screwed to the outer surface of the mouth and neck 4.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The container of the present invention is formed by a rigid outer container 1, an inner container 3 for accommodating a creamy substance, and a cap 6. The rigid outer container 1 is fitted from the upper end of a body 9 via a shoulder. The cylinder 8 is erected, and the engagement ridge 1 is
0 is attached.

The inner container body 3 is provided with a fitting cylinder 8 of the outer container body 1.
It has an outer cylindrical portion 11 fitted to the outer surface, and the upper surface of the engaging projection provided on the inner surface of the lower end portion of the outer cylindrical portion is engaged with the lower surface of the engaging ridge 10 so as to be capable of forcibly climbing over. At the upper end of the outer cylindrical portion 11, an inward flange-like wall 7 having an outer peripheral portion tapered to an inward height is attached, and the cylindrical wall of the mouth and neck portion 4 rising from the inner peripheral edge of the inward flange-like wall is attached. It is extended downward and the inner surface of the mouth of the synthetic resin sheet bag 5 is airtightly connected to the lower part of the extension forming portion 4a, and the bag is filled with a cream.

Reference numeral 7 denotes a vertical pump, which is very well known and has nothing to do with the gist of the present invention.
A mounting cylinder that is vertically installed from an upper portion of the cylinder 13 through an outward flange-like wall and that can be screwed to the outer surface of the mouth and neck 4;
Further, from the inside of the cylinder 13, an operating member having a cylindrical piston (not shown) at the lower end of the stem 14 and a push-down head 15 with a nozzle 16 at the upper end of the stem 14 is urged upward to stand up, and the push-down head 15 is pushed down. When lowered, the liquid in the cylinder 13 is pressurized and discharged from the nozzle 16,
Further, when the head 15 is released, the cylindrical piston rises and the inside of the cylinder 13 becomes negative pressure, so that the liquid is sucked into the cylinder 13. Reference numeral 12 denotes packing.

In the case of using a stored cream-like material, the cap 6 is unscrewed from the state shown in the drawing, and the mounting cylinder of the vertical pump is screwed to the outer surface of the mouth and neck portion 4 of the inner container 3. When the press-down head 15 is pressed down from this state, the stored cream-like material is discharged from the nozzle 16 in the same manner as in a normal vertical type pump-injection container. When the stored cream-like material has been used up, the mounting cylinder of the vertical pump is unscrewed from the mouth and neck portion 4 and the outer cylinder portion 11 of the inner container body 3 is fitted to the outer surface of the fitting cylinder 8 of the outer container body 1. And remove the bag 5 of the inner container 3 from the outer container 1
The outer container body 1 is taken out from the inside of the body portion 9 and the outer container body 1 is separated and discarded for reuse.

[0010]

According to the present invention, the present invention has the above-mentioned structure. The upper cylindrical portion 11 is fitted to the outer surface of the fitting tube 8 of the outer container body 1 so as to be able to be forcibly extracted through the inward flange-like wall 7. The mouth and neck portion 4 is raised and the cylindrical wall of the mouth and neck portion is formed to extend downward, and the inner surface of the mouth portion of the bag portion 5 is airtightly connected to the lower portion of the extension formed portion 4a. Can be easily taken out of the body 9 of the outer container body 1 by using the knob as a knob, so that the outer container body 1 and the inner container body 3 are separately discarded and removed. Since the container body 1 can be reused, and the inner container body 3 can be folded and discarded, it can contribute to reduction of waste. Further, since the bag portion 5 of the inner container body 3 is stored in the body portion 9 of the rigid outer container body 1, the rigid outer container body 1 serves as a protective case for the bag portion 5 in the distribution process, and other objects are stored in the bag portion 5. It can be prevented from being broken by contact.
