DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
As shown in the drawings, the eyewash container 1 of the present invention includes a container body A and a nozzle B.
[0011]
The container body A is formed of a synthetic resin or the like, and has an outer layer 4 having a shape-retaining property in which the mouth and neck portion 3 stands up from the squeezable body portion 2, and an outer layer having an upper end opened in the mouth and neck portion 3. 4 and a flexible inner layer 5 filled with liquid.
[0012]
The inner layer 5 constituting the container body A may be a so-called Delami bottle type that is releasably laminated on the inner surface of the outer layer 4 as shown in the drawing, or is simply housed in the outer layer 4 although not shown. Also good. The outer layer 4 is preferably provided with an outside air introduction hole 6 for introducing outside air into a gap generated between the inner and outer layers as the liquid in the inner layer 5 decreases. As shown in the illustrated example, the outside air introduction hole 6 may be provided in the mouth / neck portion 3 or other portions, and an appropriate location, size, etc. may be selected as necessary.
[0013]
The nozzle B includes a jet port 7 in the upper portion, and a discharge valve 8 in a liquid flow path a that connects the jet port 7 and the inside of the inner layer 5. The spout 7 may be directed to the side as in the illustrated example, or may be opened to the upper end surface although not illustrated. The discharge valve 8 can take various forms, and as shown in the illustrated example, it opens at a predetermined hydraulic pressure and automatically closes when the pressure is reduced to a predetermined pressure. An on-off valve type that opens and closes with its own weight can be used, but is not limited thereto.
[0014]
Hereinafter, the illustrated example will be described in detail. In the example of illustration, the nozzle B is comprised from the mounting cylinder member 9, the valve seat member 10, the valve member 11, and the jet nozzle member 12, and it forms by assembling these members.
[0015]
The mounting cylinder member 9 is formed of a synthetic resin or the like, and extends a top plate 15 with a through hole 14 inward from the upper end of the mounting cylinder 13 that is liquid-tightly fitted to the outer periphery of the mouth neck portion 3. A support cylinder 16 is erected from the periphery of the upper surface of the top plate 15. On the outer periphery of the support cylinder 16, a thread for screwing the cap 17 is provided. Then, a ring-shaped packing 18 is provided on the upper surface of the mouth-and-neck portion 3 to impart liquid tightness, and the container body A is detachably mounted. The provision of liquid-tightness is not limited to the above-described packing, and a seal cylinder suspended from the lower surface of the top plate 15 may be tightly fitted to the inner surface of the mouth neck portion 3 portion of the container body.
[0016]
The valve seat member 10 is also formed of a synthetic resin or the like, and extends a bottom wall 21 having a valve hole 20 communicated with the through hole 14 from the lower end edge of the peripheral wall 19 fitted to the lower portion in the support cylinder 16. In addition, a valve seat 22 projects from the upper surface of the bottom wall 21 around the periphery of the valve hole 20.
[0017]
The valve member 11 is made of a flexible and elastic material such as an elastomer, and a plurality of circumferentially projecting projections are provided from the inner peripheral surface of the fitting cylinder 23 fitted to the inner periphery of the peripheral wall 19 of the valve seat member 10. The valve plate 25 is extended through the elastic connecting piece 24, and the valve seat 22 is closed by the valve plate so as to be opened and closed to constitute the discharge valve 8. Therefore, the discharge valve opens against the elastic force of each elastic connecting piece 24 at a predetermined hydraulic pressure, and automatically closes by the elastic restoring force of the elastic connecting piece 24 when the pressure drops below the predetermined hydraulic pressure. It is configured as follows. If such a valve member is used, the valve plate 25 of the discharge valve 8 can be closed immediately after the liquid is ejected, so that the liquid breakage at the ejection port 7 is improved. The valve member 11 is not limited to the illustrated example, and any valve member that includes a valve plate that closes the opening of the valve seat 22 so as to be openable and closable and that is fitted in the valve seat member 10 can be employed.
[0018]
The spout member 12 is formed of a synthetic resin or the like. The lower end of the support cylinder 16 is closely fitted to the upper part of the inner periphery of the support cylinder 16 so as to stand upward, and the lower end of the columnar space 26 is opened above the valve plate 25. An ejection path 27 extending from the upper part to the side ejection port 7 is formed. Accordingly, the liquid flow path a in the illustrated example is constituted by a portion that passes from the through hole 14 to the valve hole 20 and reaches the ejection path 27 through the columnar space 26. In addition, the spout member 12 keeps the fitting width constant by abutting and locking the flange 28 projecting at a predetermined position on the outer periphery to the upper surface of the support cylinder 16, and the lower end portion is reduced in diameter to the inside of the fitting cylinder 23. I am letting. The ejection path 27 may be inclined slightly upward as shown in the illustrated example, or may be provided in the horizontal direction, or may be configured as a simple passage as in the illustrated example to eject liquid in a rod shape, or A known spraying device may be installed in the ejection path so as to enable spraying. The spout member 12 is not limited to the example shown in the figure, and the bottom portion is closely fitted on the inner peripheral upper portion of the support cylinder 16 so as to stand upward, and the top spout 7 is communicated with the valve plate 25 above. Can be used.
[0019]
In the case of using the eyewash container 1 configured as described above, for example, if the spout 7 is positioned in front of the eyeball with the cap 17 removed and the body 2 of the outer layer 4 of the container body A is squeezed, the container is stored. The liquid is pressurized, opens the discharge valve 8 and is ejected from the ejection port 7 through the liquid flow path a to wash the eyes. When the squeezing of the body portion 2 is released, the discharge valve 8 is closed, the outside air is introduced from the outside air introduction hole 6 into the gap with the inner layer 5 generated by the elastic restoring force of the outer layer 4, and the inner layer 5 is maintained in a contracted state. .
[0020]
FIG. 2 shows another embodiment, in which a treatment liquid reservoir 29 is provided at the outer lower part of the nozzle B on the side of the jet port 7. The treatment liquid reservoir 29 has a cup shape for storing the ejected eyewash liquid, and can be formed integrally with the nozzle B or formed separately as shown in the drawing. By providing the treatment liquid reservoir 29, the ejected liquid is accumulated there and is not contaminated.
[0021]
The treatment liquid reservoir 29 in the illustrated example is formed integrally with the mounting cylinder member 9. The bottom wall extends from the lower end edge of the peripheral wall 13 on the jet outlet 7 side, and a part of the peripheral wall 13 is part of the peripheral edge of the bottom wall. A peripheral wall that is shared with the part and tilts downward as it goes to the peripheral wall 13 side is provided.
[0022]
【The invention's effect】
As described above, the eye wash container of the present invention can be washed with a simple operation, and since the inner layer 5 contracts as the liquid decreases, contact between the outside air and the stored liquid can be avoided as much as possible. It is possible to prevent contamination of the liquid by various germs inside. Moreover, it can be assembled easily.
[0023]
Further, the eye wash container of the second means has an advantage that the storage space for storing the liquid can be efficiently utilized because the inner layer 5 is initially laminated with the outer layer 4 without any gap.
[0025]
Further, the eye wash container of the third means is convenient in that it does not stain the surroundings even if the eye wash is not performed in a place where water can flow, such as a washing place, a bathroom or the outdoors.
