  The pump container of Patent Document 1 is configured such that the liquid in the container body is discharged from the discharge port by moving the operation portion up and down. However, the outside air is introduced into the container body due to the decrease in the liquid. It is composed. Therefore, it is not suitable for storing liquids that are not preferably in contact with outside air. Similarly, the liquid ejector described in Patent Document 2 is not suitable for storing liquids that are not preferably in contact with outside air.

  The present invention is suitable for the case of using such a liquid that is not preferable to contact with the outside air. The liquid can maintain the quality of the stored liquid not only during storage but also after the start of use, and is easy to handle. A dispenser is proposed. In addition, when the lid plate that closes the upper end opening of the tube container mouth neck is cut and opened, the liquid in the tube container can be easily opened even if the flow path is closed by the cut lid plate. We propose a liquid ejector that can pump up water. Furthermore, the present invention proposes a liquid ejector capable of exhibiting effects such as stable liquid ejection, good liquid drainage, good sealing of the ejection port, easy depression of the head, and good durability.

  The liquid ejector of the present invention includes a tube container and a pump. The tube container is made of synthetic resin and has a flexible body that deforms so that the volume decreases as the liquid is reduced when the stored liquid is discharged. Is closed by a cover plate that can be pressed and cut.

  The lid plate is fixed to the mouth and neck by an appropriate fixing means such as fusion or adhesion using a single sheet or film of synthetic resin, or a laminated sheet or film of synthetic resin and metal thin film layer.

  The pump is basically formed of a synthetic resin except for a metal coil spring or the like, and is formed using an elastomer or the like as necessary. In addition, by moving up and down an operating member having a pressing head at the upper end, the liquid in the tube container is sucked up and discharged by the action of the built-in pump mechanism, and the pump mechanism is of a known form. Although it can be used, it is necessary to provide a connecting pipe that communicates the inside of the cylinder at the lower end and communicates the inside of the tube container and the inside of the cylinder by pressing and cutting the lid plate when the cylinder is provided on the mounting cap. Also, before use, the pump mounting cap is screwed onto the tube container neck in a state before the lid plate is cut. Note that the mounting cap may be screwed directly to the outer periphery of the mouth neck portion or indirectly through a cylindrical member.

  In the present invention, the connecting pipe has a cutting blade suspended from the lower surface. The cutting blade has an acute lower end edge, and the shape can be various forms such as an annular shape or a plate-like shape. Those having a sharp lower end edge that descends, or those having a plate-like sharp lower end edge that hangs downward from a part of the lower surface of the connecting pipe are employed. Specific examples of the former include those that are inclined downward or those that are curvedly bent. When the connecting pipe and the cutting blade are provided integrally, it is reasonable to think that there is no substantial boundary, but considering the provision of a liquid passage part on the cutting blade, the lower end surface of the connecting pipe is conveniently provided. It is good to consider that it is a horizontal ring and the cutting blade is continuously suspended from it. Therefore, it is naturally conceivable that an annular portion is present at the upper end portion even in the case of a plate-shaped cutting blade.

  The cutting blade is provided with a liquid passing portion. The liquid passage part is provided as a measure to prevent the liquid from being pumped from the tube container into the pump by the lid plate pressed and cut when opened, blocking the liquid passage of the connecting pipe. Grooves or combinations thereof can be employed. Even if the lid plate cut off due to the presence of the liquid passage portion may block the lower end opening of the connecting pipe, the liquid in the tube container is sucked into the liquid passage pipe through the liquid passage, and the normal pump Demonstrate the function. The number of liquid passing portions may be one or plural, and is appropriately selected depending on the size of the pump and the like. Moreover, the shape is not particularly limited.

  As a first means, there is provided a tube container A having a flexible body portion 2 and having an opening of the mouth-neck portion 4 closed with a cover plate 5 that can be pressed and cut, and a pump C attached to the tube container. The pump C has a cylinder 31 erected on a mounting cap 30 that is screwed to the tube container neck 4, and a stem 43 that is erected above a piston 44 that slides on the cylinder 31. And an operating member 32 provided so that it can be pushed in an upward biased state with the pressing head 45 attached thereto, and the connecting cap 35 suspended from the lower end of the mounting cap 30 in the state before the lid plate 5 is cut. 4 is a liquid discharger that is configured to be screwed to the outer periphery, to lower the mounting cap 30 at the time of opening, and to press and cut the cover plate 5 by the connecting pipe 35 so that the tube container A and the cylinder 31 communicate with each other. The cutting blade 36 is suspended from the lower surface of the connecting pipe 35, and the liquid is passed through the cutting blade 36. 37 was formed through.

  As a second means, in the first means, the pressing head 45 is provided with a mounting cylinder member 50 in which a sliding cylinder 56 that communicates with the inside of the stem 43 from a top plate 55 provided on the stem 43 is provided. A main body 51 provided with a valve chamber R having a discharge port 61 opened at the tip thereof and capable of being pushed down with respect to the mounting cylinder member 50 above the cylinder cylinder 60 slidably fitted on the outer periphery of the sliding cylinder. A valve member 52 that closes the discharge port 61 in the valve chamber R in a forward-biased state and that defines a flow path from the inside of the cylinder cylinder 60 to the discharge port 61, and a rear end of the valve member 52 The upper end is linked to the upper part, the lower end is brought into contact with and locked to the upper surface of the top plate 55, and the valve member 52 is pivotally attached to the main body 51 so that the valve member 52 can be pulled out rearward when the main body 51 is pushed down against the mounting cylinder member The pressing force of the main body 51 against the stem 43 is smaller than the pressing force of the stem 43 itself. Configuration was.

  As a third means, in either of the first means or the second means, the cutting blade 36 has an acute lower end edge 36a that is annular and descends sequentially from one of the opposing positions to the other. The liquid passing part 37 is configured to be a through hole 37a penetrating the cutting blade 36.

  As a fourth means, in any one of the first means and the second means, the cutting blade 36 has a plate-like shape suspended from a part of the lower surface of the connecting pipe 35 and has an acute angle. The lower end edge 36a is provided, and the liquid passing portion 37 is formed as a through hole 37a penetrating the cutting blade 36.

  As described above, the liquid ejector of the present invention has almost no air in the tube container before opening, and the opening of the mouth neck 4 is closed. It can be prevented from touching, and the tube container body deforms to reduce the volume as the liquid in the tube container decreases as the liquid is discharged, so there is no air intrusion into the tube container. Therefore, long-term quality maintenance of the stored liquid can be performed even after opening. In addition, when opening, a cutting blade is provided on the lower surface of the connecting tube, so it is easy to press and cut the cover plate. In addition, the liquid in the tube container can be pumped into the pump.

  Further, when the pressing head 45 of the second means is provided, the tube container A and the discharge port 61 communicate with each other through the cylinder 31 after opening, and the discharge port 61 is always closed except during discharge. Therefore, contact with air can be more reliably prevented after opening. In addition, it also exhibits effects such as good liquid drainage, good sealing of the discharge port, easy depression of the head, and improved durability.

  Further, the cutting blade 36 is provided with an acute lower end edge 36a that is annular and descends sequentially from one of the opposing positions to the other, and the liquid passing portion 37 is a through hole 37a that penetrates the cutting blade 36. In this case, the cutting blade 36 is easy to cut because the area where the cutting blade 36 first contacts the lid plate 5 is small, and even if the cut lid plate may block the lower end opening of the cutting blade 36, the tube is passed through the through hole 37a. The liquid in the container A is sucked into the connecting pipe 35, and the liquid can be discharged smoothly.

  Further, the cutting blade 36 has a plate-like shape suspended from a part of the lower surface of the connection pipe 35 and has a sharp lower end edge 36a, and the liquid passing portion 37 penetrates the cutting blade 36. In the case where it is configured as 37a, it is easy to cut similarly, and smooth liquid discharge can be performed.

Further, the top wall 63 is extended from the upper end edge of the peripheral wall 62, and a bottom cylinder opening is formed, and a horizontal cylinder 64 having a front end opened at the front of the peripheral wall 62 is extended rearward. A cylinder cylinder 60 is suspended from the lower surface of the cylinder 64. A discharge port member 65 is fitted into the horizontal cylinder 64 to define a valve chamber R, and the cylinder cylinder 60 is fitted to the slide cylinder 56 so as to be slidable down. It is worn together. In addition, a space is provided in the rear part of the horizontal cylinder 64 so that the upper portion of the flange member 53 can be accommodated. A window hole is formed in the center of the rear wall, and a seal cylinder 66 is projected forward from the front surface of the rear wall. Furthermore, a communication port communicating with the inside of the cylinder cylinder 60 is provided at the lower part. Further, at a predetermined position on the outer periphery of the peripheral wall 62, there is provided a protrusion 68 that moves up and down in the annular recess 39 of the guide tube 38 and is locked to the upper surface of the annular recess to prevent the operating member 32 from coming off.

  The discharge port member 65 fitted to the horizontal cylinder 64 is configured to open the discharge port 61 at the tip to form the valve chamber R together with the horizontal cylinder. The rear part is liquid-tightly fitted to the front part in the horizontal cylinder 64, and The front part is tapered and the discharge port 61 is opened at the tip. Further, an annular protrusion protruding from the outer surface is brought into contact with and locked to the front surface of the main body 51, and a plurality of circumferential ribs are protruded inside.

  The valve member 52 has a horizontal bar shape. The skirt-like portion extends rearward from the intermediate portion in the longitudinal direction of the outer periphery, and the outer peripheral edge of the reverse skirt-like portion folded back from the rear edge of the skirt-like portion slides on the inner periphery of the seal cylinder 66. It is movably fitted. Further, the front end of the horizontal cylinder 64 is biased forward by a coil spring 67 interposed between the front surface of the rear wall of the horizontal cylinder 64 and the branched portion of the skirt-like portion, and the front end is pressed against the discharge port 61 to be closed. Further, the rear end is projected from the window hole, and an annular recess for engaging the flange member is provided in the projected portion. As a result, a flow path from the cylinder cylinder 60 through the communication port to the discharge port 61 through the horizontal cylinder 64 is defined.

  The flange member 53 is pivotally mounted so as to be able to swing the valve member 52 backward when the main body 51 is pushed down with respect to the mounting cylinder member 50, and the valve protruding rearward through the window hole in the rear wall of the horizontal cylinder 64 The upper end is linked to the rear end portion of the member 52, and the lower end portion is in contact with and locked to the top surface of the top plate 55. The eaves member 53 has a form as shown in FIG. 8, and extends a bifurcated inclined plate portion 71 whose upper end portion is linked forward to the rear end portion of the valve member 52 and descends forward from the lower end portion of the vertical plate portion 70. The lower end portion of the inclined plate portion 71 is brought into contact with and locked to the upper surfaces of the top plates 55 on both sides of the sliding cylinder 56. The linkage between the flange member 53 and the valve member 52 in this embodiment is such that the annular recess of the valve member 52 is fitted into a notch provided in the center of the upper end portion of the vertical plate portion. Further, pivot shafts 72 projecting on both sides of the refracting portion are fitted to the bearings on both sides in a rotatable manner.

  Further, the pressing force of the main body 51 against the stem 43 is configured to be smaller than the pressing force of the stem itself. In order to configure in this way, basically, the spring force of the coil spring 67 for biasing the valve member 52 forward should be selected smaller than the coil spring 43 for biasing the stem 43 upward. In addition, these may be selected in consideration of the frictional force between the sliding cylinder and the cylinder cylinder, the frictional force when the saddle member is swung, and the like.

  In the liquid jet pump C configured as described above, when the cover cap 23 and the spacer 42 are removed from the state of FIG. 1 and the mounting cap 30 is screwed down, as shown in FIG. The plate 5 is pressed and cut, and the tube container A and the cylinder 31 communicate with each other. At this time, the packing 48 is sandwiched between the mounting cap top wall 34 and the upper flange 12 of the cylindrical member 10 to impart liquid-tightness to this portion. Next, when the pressing head 45 is pressed down, the pressing force of the stem 43 itself is greater than the pressing force of the main body 51 against the stem 43, so that the first stem 43 does not drop and the main body 51 moves down with respect to the mounting cylinder member 50. At this time, the lower end portion of the flange member 53 is pushed up to the upper surface of the top plate 55 of the mounting cylinder member 50 and pivots about the pivot shaft 72, and the upper end portion pivots rearward so that the valve member 52 is moved to the coil spring 67. The discharge port 61 is opened by moving backward against the elastic force. Next, the stem 43 is lowered, the inside of the cylinder 31 is pressurized by the lowering of the stem, the piston 44 is raised relatively to the stem 43 and the through hole 47 is opened, and the pressurized liquid moves the cylinder cylinder 60 from the stem 43. As a result, the liquid is ejected from the discharge port 61 to the outside through the flow path from the communication port.

  Next, when the pressing of the pressing head 45 is released, the head is raised by the upward biasing force of the stem first. At this time, for example, the stem is raised before the hand pressing the upper surface of the pressing head 45 is released, and the discharge port 61 is kept open. Therefore, at this time, the inside of the horizontal cylinder 64 is in a negative pressure state. Next, there is room for releasing the hand, and the valve member 52 moves forward due to the elastic force of the coil spring 67 to close the discharge port 61. Accordingly, the main body 51 is moved upward with respect to the mounting cylinder member 50 by the flange member 53. To return to the original state. Further, as the stem 43 is raised, the piston 44 is relatively lowered to close the through hole 47 and the inside of the cylinder 31 becomes negative pressure, so that the suction valve 40 is opened and the liquid in the tube container A is in the cylinder 31. To be introduced. The body 2 of the tube container A is deformed so as to reduce its volume as the liquid is introduced into the cylinder 31. At this time, as shown by a two-dot chain line in FIG. 7, the following is introduced into the cylinder 31 from the through-hole 37 even if the cut piece 5 a of the cover plate closes the lower end opening of the cutting blade 36.
