BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
As shown in FIG. 1, the double-headed liquid ejection container 1 of the present invention projects a pair of ejection heads 3 (3a, 3b) having ejection ports 2 and 2 from the upper end so as to be able to be pushed down in an upwardly biased state. By moving each ejection head 3 up and down, the liquid in the storage section communicating with the ejection port of each head is ejected from each ejection port. The ejection mechanism for ejecting such a liquid may be of a known type, for example, a known pump type having a cylinder or a piston, or an aerosol type of ejecting the liquid by gas pressure. Can be adopted.
[0011]
The double-headed liquid ejection container 1 in the illustrated example includes a case body A, a pair of container bodies B, B, a pair of pumps C, C mounted on each container body, and a shoulder cover D.
[0012]
The case body A fits each container body, and has a bottomed cylindrical shape in which the peripheral wall 5 stands up from the peripheral edge of the bottom wall 4. A small outer diameter portion 6 having a smaller outer diameter than the peripheral wall 5 is provided around the upper end of the peripheral wall 5.
[0013]
Each of the container bodies B, B has a mouth and neck 8, 8 having a diameter smaller than that of the body, standing from the upper end of the body 7, 7, the inside of which is a liquid storage section. 7, 7 are fitted and mounted. Each body is fitted into the case body A without rattling. In the illustrated example, the left and right central side faces are formed in a semi-elliptic cylindrical shape, and the flat surfaces of both container bodies are brought into contact with each other. It is configured so that it fits perfectly into the case body A in this state.
[0014]
Each of the pumps C, C has a mounting cylinder 9, 9 fitted to each of the mouth and neck portions 8, 8, respectively, and is mounted on each of the containers B, B, and can be pushed down at the upper end in an upwardly biased state. 3a and 3b are protrudingly provided. Each pump is provided with a known pump mechanism, and will be described without illustration. For example, a cylinder having an upper end fixed by a mounting cylinder 9 is suspended in a container body, and a suction pipe is fitted to a lower end of the cylinder. It hangs at the lower end of the container. Further, a stem, which is provided with a piston slidably fitted in the cylinder from the lower part of the outer periphery, is provided so as to protrude above the cylinder, and an ejection head is fitted to the tip of the stem. Further, a suction valve is provided in a lower portion of the cylinder, and a discharge valve is provided in the stem.
[0015]
In the illustrated example, the mounting cylinder 9 has a guide cylinder 11 erected upward through a flange 10 extending inward from the upper end edge thereof, and the ejection head 3 has a crest at a lower end opening. It has a cylindrical shape, and nozzles 12 and 12 project from the upper end of the front part, respectively, and jet ports 2 and 2 are opened at the tip of each nozzle. The peripheral wall of the ejection head 3 has a flat elliptical cylindrical shape on the left and right center sides, and is slightly tapered upward.
[0016]
The shoulder cover D has the lower end of the peripheral wall 13 fitted to the upper end of the case body A, and both the ejection heads 3a and 3b are protruded so as to be able to be pushed down from a window hole in the center of the top wall 14 extending from the upper end of the peripheral wall 13. In the illustrated example, a fitting tubular portion 15 fitted to the outer periphery of the upper end of the small outer diameter portion 6 of the case body extends from the lower peripheral portion of the peripheral wall 13 via the flange 16, and also extends from the rear surface of the top wall 14. A fitting tube 17 fitted around the outer periphery of the two mounting tubes 9 is vertically provided.
[0017]
In the present invention, in the above-described double-headed liquid ejection container, it is supported so as to be rotatable from a state of being placed on the top surface of one ejection head 3a to a state of being placed on the top surface of the other ejection head 3b. Plate 18 is provided. By providing such a plate 18, if the plate 18 is rotatably mounted on the other ejection head 3b that does not eject the liquid, the pressed portion of one ejection head 3a that ejects the liquid becomes clear, and an error is caused. This can prevent the inconvenience of pushing down the other head. Further, even if a finger pressed when the one ejection head 3a is pushed down slightly protrudes, the presence of the plate 18 hinders the other ejection head from being pushed down.
[0018]
The support means of the plate 18 can be variously selected as long as the above requirements are satisfied. As an example, a support plate 19 supported by the shoulder cover D is erected between the ejection heads 3a and 3b, and an upper end of the support plate 19 is provided. The plate 18 can be rotatably connected to one end of the ejection head 3a so as to be rotatable from the top surface of one ejection head 3a to the top surface of the other ejection head 3b.
[0019]
In the illustrated example, a support plate 19 is erected between the two ejection heads 3a and 3b from a connecting rod 20 which extends back and forth over a middle portion of the fitting cover 17 of the shoulder cover D in the left-right direction. A recessed bearing recess 21 extending in the front-rear direction is formed on the upper surface of the lens. The bearing recess 21 includes a hollow cylindrical bearing at the lower end, and a tapered introduction groove extending from the bearing and opening on the upper surface and having a wide upper portion.
[0020]
The plate 18 has a semi-elliptical plate shape that is similar to the top surface of the ejection head and has a notch recess 22 at the center, and a columnar shaft 23 spans the edge of the recess. It is composed. The shaft 23 is rotatably fitted to the bearing portion of the bearing recess 21 and mounted.
[0021]
Although the size and shape of the plate 18 are not particularly limited, the plate 18 can be rotated as described above, and in consideration of frequent rotation, a plate having a portion protruding from the peripheral edge of the top surface of the ejection head is preferably used. This is preferable because it can be easily rotated with a finger.
[0022]
The plate 18 may be provided with display marks 24 on the front and back thereof. As the display mark 24, various forms such as characters describing the type of liquid ejected from the other ejection head, symbols such as arrows, pictures, patterns and the like can be adopted. For example, a display mark 24 indicating the type of liquid ejected from the other ejection head 3 is formed on one surface serving as the front surface while being placed on one ejection head 3, and one ejection head 3 is formed on the back surface. A display mark 24 indicating the type of liquid to be ejected is formed. Alternatively, as in the illustrated example, a symbol or the like that is not directly related to the type of liquid, such as an arrow, may be provided. These display marks may be provided by printing, or may be formed by sticking a sealing material having a printing layer.
[0023]
In the double-headed liquid ejection container 1 configured as described above, for example, if one ejection head 3a on which the plate 18 is not placed is pressed from the state of FIG. 1, the liquid in one container body B is ejected from the ejection port 2. I do. At this time, since the other ejection head 3b has one end rotatably supported by the plate 18 at the center, even if the pressing finger is slightly displaced toward the other ejection head, its pivotally attached portion is not pushed down. Therefore, the other ejection head 3b is not accidentally pushed down. When the liquid in the other container body B is to be ejected, the plate 18 is rotated on one ejection head 3a, and then the other ejection head 3b is pushed down to eject the liquid from the ejection port 2. .
[0024]
FIG. 4 shows another embodiment, which is different from the embodiment of FIG. 1 in the structure of the support plate and the plate. In the present embodiment, the plate 18 is rotatably provided via a bearing member 25 fitted to a support plate 19 erected between the ejection heads 3a and 3b. The bearing member 25 is fitted to the support plate 19 so as to be horizontally rotatable, and therefore can be rotated horizontally with the plate 18 standing upright.
[0025]
More specifically, the support plate 19 connects the outer surfaces of the lower end portions to the front and rear inner circumferences of the top wall 14 of the shoulder cover D, and stands upright. Provided. The bearing member 25 has a bearing portion 28 having a bearing recess 21 similar to that of the embodiment of FIG. 1 on an upper portion of a connecting shaft 27 rotatably fitted to the shaft support portion 26. A plate 18 similar to that of the embodiment of FIG. The other points are substantially the same as those in the embodiment of FIG.
[0026]
【The invention's effect】
As described above, the liquid ejection container of the present invention has the above-described configuration, so that the ejection head on the side to be ejected can be easily visually recognized at the time of ejecting the liquid, and the ejection head that does not eject can be prevented from being pushed down. It is possible to prevent errors such as erroneously pushing the other ejection heads at the same time, and to surely eject only one necessary liquid. Further, since the plate moves onto the other ejection head only by rotating, the switching of the ejected liquid can be easily performed.
[0027]
In addition, in the case where the display mark is provided on the front and back of the plate, the type of the liquid ejected from the ejection head on the opposite side where the plate is not mounted can be displayed, so that the usability is further improved.
[0028]
Further, in the container according to the third aspect of the present invention, as described above, only one of the liquids can be reliably ejected, and the switching is easy. Since it is stored in the shoulder cover, the appearance is good, and the whole can be formed compactly without rattling, so that handling becomes more convenient.
