Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spray container for jetting a liquid.

[0002]

[Prior art]

 The spray containers for liquids can be broadly classified into two types: liquefied gas pressure type and metering pump type. The liquefied gas pressure type uses the pressure of liquefied chlorofluorocarbon gas or liquefied propan gas filled in the tank in the container to eject the liquid inside, and is characterized by being continuously ejected. The metering pump type is characterized in that a certain amount of liquid is ejected by pushing down the knock body of the nozzle.

[0003]

[Problems to be solved by the device]

 The liquefied gas pressure type spray container is restricted because it uses flammable gas and has a problem of depleting the ozone layer like CFC gas, and it is necessary to reuse the used container. It is uneconomical because it cannot be done. On the other hand, in the case of the metering pump type spray container, the liquid cannot be ejected continuously, and the knock body must be pushed down each time, and the pump structure is complicated and the number of parts is large, resulting in a low manufacturing cost. There is a problem of being expensive.

An object of the present invention is to provide a spray container which can use a liquid as it is without using a liquefied gas and can continuously eject.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the spray container according to the present invention is provided with a cap having a nozzle body for spraying which opens a valve by pushing a knock body on a lower threaded portion of a cylindrical body to which a cap is detachably attached. The screw part of the adjusting cylinder whose bottom and upper part are opened is screwed so that it can move up and down, and the lower part inside the body is provided with a rising force by a compression spring provided on the inner bottom of the adjusting cylinder. A plate is provided freely, and a flexible container having an opening at the upper end communicating with the valve and having a liquid for spraying contained therein is provided on the seat plate.

[0006]

[Action]

 The valve of the nozzle body is opened by pushing the knock body, and the liquid inside the container, which is pressurized by the compression spring provided in the adjusting cylinder, is ejected from the nozzle through the opened valve. Further, when the adjusting cylinder is rotated in the forward and reverse directions, it is guided by the lower screw of the body to be moved up and down, whereby the spring pressure of the compression spring applied to the container is adjusted and the ejection pressure of the liquid is adjusted.

[0007]

【Example】

 Hereinafter, a specific example of the spray container according to the present invention will be described in detail with reference to FIGS. In the figure, reference numeral 1 is a body for a container, 2 is a cap having a nozzle body 9 for spraying, 3 is an adjusting cylinder for adjusting the pressure of liquid in a container, and is an upper part of the cylindrical body 1. Is provided with a reduced diameter portion 1a, and an upper threaded portion 4 is formed on the outer periphery of the reduced diameter portion 1a, and the threaded portion 2a formed on the lower inner peripheral surface of the cap 2 is attached to the threaded portion 4 of the reduced diameter portion. The cap 2 is detachably attached to the body 1 by screwing.

Further, a lower threaded portion 5 is formed on the outer periphery of the lower portion of the body 1, and a threaded portion 3a formed inside the bottomed adjustment cylinder 3 having an open upper portion is screwed into the lower threaded portion 5. There is. The adjusting cylinder 3 has a compression spring 7 inside, and a seat plate 6 for pushing up the bottom of the container 8 is provided at the upper end of the adjusting cylinder 3 so that it can slide up and down along the inner wall of the body. There is.

A container 8 containing a liquid for spraying is housed inside the body 1, and the container 8 is a flexible, for example, bellows-shaped synthetic resin container, and has a thick-walled portion above the opening. 8a is formed, and the thick portion is fitted into the reduced diameter portion 1a of the body 1 from the inside, and the opening edge of the container is connected to the upper end of the reduced diameter portion of the body and the seal 12 attached to the inner surface of the cap 2. There is a cramp in between.

The nozzle body 9 provided on the cap 2 may be of a type in which the valve is opened by pushing the knock body 10, and an example thereof is enlarged and shown in FIG. Reference numeral 13 in the drawing is a valve body for opening and closing the flow of liquid, 14 is a valve seat provided in the center of the cap, and 15 is a compression spring for holding the valve body 13.

The valve body 13 has a bottomed tubular shape with an open upper end, and has a diameter-expanded taper portion 13a formed in the lower portion and a same-diameter portion 13b formed in the upper portion, and a plurality of valve holes 13c formed in the side surface of the taper portion. I have

The valve seat 14 is formed so as to rise like an inverted funnel from the peripheral edge of the opening 2b opened in the center of the cap, and the tapered surface 14a following the opening 2b of the cap has a shape following the tapered portion 13a of the valve body. When the taper portion 13a of the valve body is pressed against the taper surface 14a of the valve seat, the valve hole 13c is closed.

A cylindrical portion 14b continuing above the tapered surface 14a of the valve seat serves as a guide for guiding the same diameter portion 13b of the valve body when the valve body slides up and down, and is located inside the opening upper end thereof. An O-ring 14c is fitted around the circumference to prevent liquid leakage.

A stopper 13d for stopping the upper end of the valve spring 15 is attached to the outer periphery of the upper portion of the same diameter portion 13b of the valve body. The stopper 13d is provided between the lower surface of the stopper 13d and the upper edge of the opening of the valve seat 14. The valve spring is sandwiched between. Further, a knock body 10 for pushing down the valve body is attached to the upper end of the same diameter portion 13b of the valve body, and has a spout 16 for discharging the liquid to the outside. The diameter of this ejection port is appropriately determined depending on the viscosity of the spray liquid. Reference numeral 11 in the figure is a guide for guiding the knocking body in the vertical direction.

The spray container thus constructed is used as follows. When the adjusting cylinder 3 is rotated forward and backward, it is guided by the lower threaded portion 5 of the body to move up and down, whereby the spring pressure of the compression spring 7 is adjusted, and the seat plate to which the upward force is applied by the spring pressure. 6 pushes up the bottom of the container 8 filled with the liquid for spraying and applies pressure to the liquid in the container.

By pushing the knock body 10 with a finger, the valve body 13 is lowered against the spring pressure of the valve spring 15 as shown in FIG. 3, and the valve hole closed by the tapered surface 14 a of the valve seat 14 is closed. 13c opens. The liquid in the container 8 enters the valve body through the valve hole 13c due to the pressure in the container, and then ejects from the ejection port 16 of the knock body 10 to the outside through the valve body.

Since the valve hole 13c is opened while the knock body 10 is pushed, the liquid body in the container is continuously ejected. When the finger is released from the knocking body, the valve body 13 is lifted by the spring pressure of the valve spring 15 and the pressure of the liquid applied to the bottom surface of the valve body, whereby the valve hole 13c of the valve body is set in the valve seat. The taper surface 14a is pressed into contact with the taper surface 14a to be blocked, and the ejection of the liquid is stopped.

[0018] As the liquid is used, the liquid in the container shrinks and the container contracts, and the compression spring 7 expands accordingly and the spring pressure becomes small. In this case, the adjusting cylinder 3 is rotated in the direction in which the adjusting cylinder rises. The spring pressure of the compression spring 7 is increased again by moving it.

In the spray container according to the present invention, the spray container main body can be reused by replacing the container, but the container is replaced as follows. The adjusting cylinder 3 and the cap 2 are removed from the body 1 in this order, and the used container 8 is taken out from the lower opening of the body.

A replacement container filled with a liquid for spraying is inserted from the lower opening of the body, and the thick portion 8a is fitted into the reduced diameter portion 1a of the body. After attaching the screw part 2a of the cap 2 to the upper screw part 4 and clamping the opening edge of the container, press the seating plate 6 against the bottom part of the container and press it with the compression spring 7 while screwing the adjustment tube to the lower screw part 5. To combine.

[0021]

[Effect of device]

 According to the spray container of the present invention, since the liquid is ejected by utilizing the spring pressure, it is possible to eject the liquid continuously without using the liquefied gas such as liquefied chlorofluorocarbon gas and the adjusting cylinder. Since the spring pressure can be adjusted by rotating it, the ejection pressure of the liquid can be adjusted.

Further, since the container is used after being replaced, the spray container itself can be reused, which is economical. Further, the structure is simple and the number of parts is small, and the manufacturing cost can be reduced.
