JPH02152570A - Method and device for packing content to non-gas sprayer - Google Patents

Abstract

PURPOSE:To easily pack a desired content into a non-gas sprayer for which a freely expandable tube is utilized by pressing the injection port of a pump into the valve mechanism in the port of a tube to open a valve, and then packing the content housed in a cylinder from an injection port into the tube by lowering of a piston. CONSTITUTION:The injection port 7 having a check valve is attached to the bottom end of the cylinder 2. An introducing valve 8 which introduces the content into the cylinder 2 and prevents back flow is provided on the side wall of the cylinder 2 and a hose 9 is connected thereto. The front end of the hose 10 is set in a tank 10 in which the content L is stored. The non-gas sprayer 11 has the expandable tube 13 in a container body 12 and is attached with a valve mechanism 14 in this port. An operator introduces a prescribed volume of the content L into the cylinder 2 by pressing the injection port 7 of the pump 1 to the valve mechanism 14 and pulling up a handle 5. The content L is packed from the injection port 7 into the tube 13 by pushing down the handle 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for filling a non-gas spray with contents.

[Conventional technology]

Sprays using chlorofluorocarbon gas are conventionally known. Products that use fluorocarbon gas have been pointed out to be harmful.
In recent years, non-gas sprays have been developed. Non-gas sprays have an expandable tube inside the container body, and the contents can be sprayed by deflating the tube. These non-gas sprays are sold after being filled in factories using extensive methods and equipment, but once the contents have been used up, users cannot easily refill them. there were.

[Problem to be solved]

There is an increasing desire for users to fill the non-gas spray described above with the desired content after they have finished using it, or for sprays that have not been filled from the beginning. Methods and filling equipment had not yet been developed.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method and an apparatus for easily filling a desired content into a non-gas spray using an expandable tube.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an inflatable tube in the container body, and an inlet with a check valve for the empty non-gas sprayer with a valve mechanism attached to the mouth of the tube. a step of pressing against a valve mechanism at the mouth of the tube to open this valve; a step of raising the piston of the pump to accommodate the contents to be filled into the cylinder; and a step of lowering the piston to transfer the contained contents to the injection port. The process consisted of a step of filling the tube from the In addition, an inlet is provided in the pump cylinder with a check valve that pushes down the valve mechanism that is pushed up to close the valve and allows only one side of communication from the inside of the pump cylinder to the inside of the tube, It is equipped with an introduction valve that introduces the contents into the cylinder and prevents backflow, and a piston that is manually moved up and down inside the cylinder.

[Effect]

According to the method of the present invention, the content is stored in the cylinder of the pump, and by lowering the piston, the valve mechanism at the mouth of the tube is removed from the injection port equipped with the check valve. It can be filled into the tube through the tube. A user using this method and device can easily fill the tube with desired contents.

〔Example〕

Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the device of the present invention.
The pump 1 has a piston 3 in a cylinder 2 that can be moved up and down, a rod 4 is attached to the piston 3, and a handle 5 is attached to one end of the rod 4 that comes out from the cylinder 2. The movement moves the piston 3 up and down within the cylinder 2 via the rod 4. An O-ring 6 is attached to the piston 3. The material used for this OIJ song is NBR rubber or the like. The piston 3 itself is made of a material that is resistant to the contents, such as stainless steel, brass, nylon, polyethylene, or polypropylene. Cylinder 2 is made of stainless steel, brass, nylon,
Polyethylene, polypropylene, vinyl chloride, etc. are suitable. An injection lower equipped with a check valve is attached to the lower end of this cylinder 2. This injection lower communicates only from the inside of the cylinder 2 to the outside. Also, cylinder 2
An introduction valve 8 (consisting of a check valve) is provided on the side wall of the cylinder 2 to introduce the contents into the cylinder 2 and prevent backflow. A hose 9 is connected to this introduction valve 8, and the tip of the hose 10 is set in a tank 10 storing contents.

The non-gas spray 11 includes an inflatable tube 13 inside a container body 12, and a valve mechanism 1 at the mouth of the tube 13.
4 is for installation. This valve mechanism 14 is constantly pushed up by a coil spring or the like, and the valve is closed in this pushed up state. When the coil spring is compressed and the valve mechanism 14 is pushed down, the inside of the tube 13 and the outside are brought into communication. When the injection lower of the pump 1 is pressed against this valve mechanism 14, since the injection lower has one-way communication from the inside of the cylinder 2 to the outside, only one-way communication from the inside of the cylinder 2 to the inside of the tube 13 is achieved.

To use a device configured in this way, handle 5
The contents are introduced into the cylinder 2 by pulling up the cylinder 2, and once a predetermined amount of contents have been introduced, the handle 5 is pushed down to fill the contents into the user 13 from the injection lower. At this time, when the piston 3 is rising, air is not taken in from the outside from the injection lower, but only from the introduction valve 8. Conversely, when the piston is pushed down, the inlet valve 8 is closed and the injection lower opens to send the contents of the cylinder 2 into the injection lower valve mechanism 14-tube 13.

The injection lower and the introduction valve 8 are each provided with a check valve,
This check valve used a ball type valve. The ball is preferably made of glass or stainless steel, and the valve body is made of brass, nylon, or polyethylene.

Polypropylene and the like are preferred. Further, it is desirable that the tank 10 also serves as a measuring cup.

In addition, the operating pressure of the non-gas spray 11 is approximately 3 kg/cd.
In this case, the diameter of the cylinder 2 is preferably about 1 to 2 cm. When the diameter of the cylinder 2 is about 1 to 2 cm, manual operation of the handle 5 can be performed smoothly.

The structure of the non-gas spray 11 is
Preferred are those described in Japanese Patent No. 1248. The cover member described in this publication is removed when filling the contents.

Although the illustrated embodiment is configured so that the handle 5 is operated by hand, it is of course possible to configure the piston 3 to be raised and lowered by stepping on it.

〔effect〕

As explained above, according to this filling method, the contents are stored in the cylinder of the pump, and the contents stored in the cylinder are transferred from the injection port equipped with a check valve to the tube by lowering the piston. It can be easily filled into the tube via the valve mechanism at the mouth, and there is no backflow. Therefore, it becomes possible to reuse the non-gas spray that has been disposable up to now, and it is also possible to fill the spray with desired contents according to the user's preference. Further, according to the device of the present invention, the structure is extremely simple and can be provided at low cost, and the user can easily and reliably fill the non-gas spray with desired contents.
