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" A vertical pump type liquid discharge container, that is, a cylinder having a suction valve at the bottom, which is hung down in the container body, and a stem 15 is erected upward from inside the cylinder to stand up the stem 15. It has an operating member with a discharge valve fitted with a push-down head with a nozzle at the upper end, and the pressure inside the cylinder is raised by pushing down the operating member against the container body, and the discharge valve opens and the liquid in the cylinder from the nozzle It is provided so that the liquid inside the container is sucked into the cylinder through the suction pipe hanging from the lower end of the cylinder by closing the discharge valve and opening the suction valve. Things are widely used.

"Problems to be solved by the invention" Conventional vertical pump type liquid discharge containers can be used only for liquids, and when used to discharge contents with poor fluidity as a creamy substance discharge container. However, there is a drawback in that it is impossible to suck the contents inside the container into the cylinder due to the formation of an air passage on the side of the suction pipe that is hung vertically inside the container. Further, since the discharge of the contents is performed by the replacement with the outside air, there is a disadvantage that the contents cannot be used for the contents which are not preferable to contact with the air, for example.

Therefore, an object of the present invention is to provide a creamy substance discharge container that can be used with a sufficient correspondence even for contents that are poor in fluidity and that are not preferable to contact with air.

[Means for Solving the Problem] In order to achieve the above object, a creamy substance discharge container according to the present invention comprises a container main body 1 in which a mouth / neck portion 4 is erected, and a cylindrical portion on the top surface of the container main body. 6 A first outward flange 7 attached to the upper end is placed and the tubular portion is hung down into the container body, and the upper portion of the tubular portion is made into the large inner diameter portion 8 and the outside air suction hole 9 is bored in the large inner diameter portion. The bag mounting cylinder 5, the tightening ring 10 fitted to the inner surface of the lower portion of the cylinder 6, and the inside of the container body are filled with a creamy substance and the opening 11a is tightened. A flexible bag 11 having a bag mouth closed by folding the ring 10 from the inside to the outside and sandwiching the folded portion between the tightening ring outer surface and the lower inner surface of the tube portion 6, and the bag attachment tube 5 Insert the lower half of the cylinder 13 into the bag 11 by passing it through honey and attach it to the upper part of the cylinder. It was the second
A pump type in which the outward flange 14 is placed on the upper surface of the first outward flange 7, and the pressing head 17 with the nozzle 16 is fitted to the upper end of the stem 15 that is erected by being urged upward from inside the cylinder. Of the creamy material discharge device 12, the peripheral wall 20 is fitted to the outer surface of the neck portion 4 of the container body mouth, and the first and second flanges 21 attached to the upper end of the peripheral wall and the top surface of the mouth portion of the container body. 2 The mounting member 19 sandwiches the outward flanges 7 and 14 from each other.

[Operation] For example, from the state shown in FIG. 1, when the cream in the bag 11 is reduced by pumping the cream dispenser 12, the volume of the bag is reduced each time to prepare for the next pumping. Due to the volume reduction of the bag, the outside air is sucked into the container body 1 through the outside air suction hole 9 of the bag mounting cylinder 5, but does not enter the bag.

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

In FIG. 1 to FIG. 3, reference numeral 1 is a container body, and a mouth / neck portion 4 is erected from an upper end of a body portion 2 through a shoulder portion 3.

5 is a bag-mounting cylinder, and a first outward-facing flange 7 attached to the upper end of the cylinder portion 6 is placed on the top surface of the container body 1 and the cylinder portion 6 is hung down into the container body 1. The upper half portion has a large inner diameter portion, and an outside air suction port 9 is bored in the large inner diameter portion. In the illustrated example, the lower half portion of the tubular portion 6 is formed as a double wall including an inner peripheral wall 6a and an outer peripheral wall 6b.

Reference numeral 10 denotes a tightening ring with a collar, which is screwed to the inner surface of the outer peripheral wall 6b.

A flexible bag 11 is housed in the container body 1 and filled with a creamy substance, and the opening 11a is folded back from the inside of the tightening ring 10 to tighten the folded portion. The bag mouth is sealed by being sandwiched between the outer surface of the ring 10 and the inner surface of the outer peripheral wall 6b.

Reference numeral 12 is a pump-type creamy substance ejector, which allows the lower half of the cylinder 13 to be inserted into the bag 11 by passing water through the bag mounting cylinder 5 and also to the second outward flange 14 attached to the upper portion of the cylinder 13. Is placed on the upper surface of the first outward flange 7,
In addition, the pressing head 17 with the nozzle 16 is fitted to the upper end of the stem 15 which is urged upward from the inside of the cylinder 13 and stands up. Reference numeral 18 in the figure denotes an outside air intake hole communicating with the outside air intake hole 9 of the bag mounting cylinder 5.

Reference numeral 19 denotes a mounting member that fits a peripheral wall 20 on the outer surface of the neck portion 4 of the container body, and the inwardly facing flange 21 attached to the upper end of the peripheral wall 20 and the top surface of the container body 1 for the first and second portions.
It is formed by sandwiching outward flanges 7 and 14.

4 and 5 show another embodiment of the discharge container of the present invention.

This is formed by forming the lower part of the tube portion 6 of the bag mounting tube 5 into a single wall 6c,
The inner surface of the single wall 6c has an outer surface of the tightening ring 10 with an uneven engaging means.
This is an example of fitting by 22a and 22b. In the drawing, 23 is an inward flange portion for sealing, and 24 is a packing.

In addition, in each of the above-described embodiments, each part is appropriately molded and manufactured from a synthetic resin material.

[Advantage of Invention] As described above, according to the present invention, the bag containing the creamy substance is put in the container body, and the suction pipe is inserted into the bag so that the bag mouth portion is against the outer wall surface of the cylinder. Since it is sealed, even if the content is poor in fluidity, it can be surely sucked up by the bag whose volume is reduced at each pumping, and even if the content is not preferable to contact the air, the bag will be Prevent it. Further, the bag can be easily attached to the opening of the container body by the bag attachment cylinder.
