Description

  The present invention relates to a dispenser for a reversing container that is disposed and used with the mouth portion of the container facing downward, and in particular, it is intended to reliably avoid dripping from the nozzle and solidification of the remaining contents. is there.

A stationary container that is fixed and used on a wall or the like while holding the container in an inverted position can take out the contents with a simple operation by operating the dispenser attached to the mouth with one hand. It is expected that the demand will increase further in the future because it is frequently used in medical institutions such as hotels, inns, hospitals, and welfare-related containers as containers for storing or cleaning liquids and disinfecting liquids (Patent Document 1). reference).
JP 2004-331115 A

  By the way, the dispenser applied to this type of container usually has a nozzle for pouring the contents in the container facing downward, and remains in the nozzle even though the dispensing of the contents is stopped. If there is a long-term non-use state (especially a hotel or inn), or if it is filled with content that tends to solidify, clog the nozzle. It was assumed that it would be easy to cause the contents to be poured out, and there was still room for improvement.

  The subject of this invention exists in the place which proposes the dispenser for novel inversion containers which can avoid the dripping reliably and can suppress the solidification of the content in a nozzle.

The present invention has an inlet that is open upward and can be connected to the mouth of a container in an inverted position, and a nozzle that is directed downward, and the contents in the container are poured by a lateral pushing operation. In a dispenser for a reversing container provided with a pressure head that discharges to the outside through an inlet and a nozzle,
The pressing head is configured to block a joint member that is slidably held along a wall surface of an inner cylinder provided inside the pressing head, a shut-off pin provided in the nozzle, and a nozzle outlet of the nozzle. A spring that elastically supports the shut-off pin; and an L-shaped lever that has one end connected to the rear end of the shut-off pin and is pivotally provided on the pressing head with the pivot pin serving as a fulcrum. The other end of the lever is pushed by the joint member in accordance with the pushing operation of the pressing head, and the lever rotates to slide the shut-off pin upward to open the jet port, while returning to the initial posture. A reversing container dispenser that closes the spout by sliding the shut-off pin downward by the repulsive force of the spring during the return operation .

In the dispenser as constituted above, by repeating the operation for pushing the lateral suction the contents of the container through the inlet has a pressure, compression pump, the joint member includes a disc-shaped body And a cylinder that is slidably connected to the discharge path of the nozzle, and a cylinder that is connected to the pump and discharges the contents sucked, pressurized, and compressed by the pump from the outlet. It is particularly preferable to have a configuration including:

  A shut-off pin that slides from the open position to the closed position (nozzle extending direction) in conjunction with the pressing and returning operation of the pressing head is incorporated into the head body of the pressing head, and only when the contents are poured out. Since the tip end of the pin is separated from the nozzle outlet and the nozzle is closed by the shut-off pin, liquid dripping does not occur. Further, even if the contents may remain in the discharge path of the press head, the nozzle outlet is kept closed unless the press head is pushed in, and the contents are oxidized by contact with the outside air. Solidification is avoided.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a view schematically showing an embodiment of a dispenser for a reversing container according to the present invention.

  In the figure, reference numeral 1 denotes a cylindrical base that is horizontally disposed and forms the basic skeleton of the dispenser. The base 1 has a concave portion 1a in the side wall portion at the rear end, and can be disposed in a case held by a fixed portion such as a wall by inserting a locking rod of a holder described later into the concave portion 1a. It is like that.

Reference numeral 2 denotes an inlet provided at the upper part of the base 1 and opened upward. The inlet 2 is provided with a socket 2a having an internal passage (which is connected non-rotatably by fitting means such as undercut, but the means is not limited) and is attached to the mouth K of the container. and Insert the tip of the adapter J with off valve engagement pipes 2a ₁ of the socket 2a,-inserting the state means (one protrusion provided on the side of such bayonets to other one provided in the side grooves or the like And is detachably connected to each other by applying a means for rotating in order to prevent unplugging.

Adapter J is (serves as a valve seat) inner tubular member that links to non-rotatably by splines or the like engagement pipes 2a ₁ of the socket 2a and J _11, the valve V located inside the inner tubular body J ₁₁ a, has become the external tube J ₁₂ Metropolitan disposed so as to surround the inner tubular body J _11, rotate the outer cylinder J ₁₂ of the adapter J with the container in a clockwise direction around or counterclockwise to outer Although a structure for opening and closing the passage between each other the valve body V and the inner tubular body J ₁₁ of the cylinder J ₁₂ is applied, the appearance in accordance reduces the amount of the contents as such inversion container pouch in the container having a flexible, such as deformation, since hardly rotates grabbed body of the container, the outer surface of the outer tubular body J ₁₂ of the adapter J, outer tubular body adapted to the adapter J the J ₁₂ can be rotated together with the container Bar M is provided (since containers are a like delamination vessel equipped with a high exterior body high containers or rigid rigidity can firmly grip the body portion of the container lever M can be omitted).

Reference numeral 3 denotes a horizontal cylinder disposed in the opening portion 1 b of the base 1. A check valve (3 points valve, etc.) 3b are arranged to open the suction port 3a ₁ when the cylinder 3 becomes negative pressure at the end wall 3a of the cylinder 3.

  A piston 4 is slidably disposed inside the cylinder 3. The piston 4 has an annular sliding body 4a that can slide while maintaining a liquid-tight state on the inner wall surface of the cylinder 3, and can move within the cylinder 3 together with the sliding body 4a. It is composed of a hollow stem 4b, and the piston 4 and the cylinder 3 constitute a pump.

  Reference numeral 5 denotes a passage connecting the injection port 2 and the cylinder 3. The passage 5 is formed inside the base 1.

  Reference numeral 6 denotes a pressing head incorporated in the opening 1b of the base 1 together with the pump. The pressing head 6 includes a head main body 6a that forms a pressing portion and a large-diameter annular peripheral wall 6b that is integrally connected to an end of the head 6a. The head 6a is provided with a discharge path r for the contents and a nozzle n having a spout h connected to the discharge path r and opened downward.

Reference numeral 7 denotes an inner cylinder integrally provided inside the annular peripheral wall 6b. Reference numeral 8 denotes a joint member that is slidably held along the wall surface inside the inner cylinder 7. This joint member 8 has a disk-like main body portion having a small cylinder 8a slidably connected to a discharge path r provided in the head 6a and a cylindrical body 8b fitted to the hollow stem 4b of the piston 4 constituting the pump. has (small tube 8a and the cylindrical body 8b is connected by passage), the suction by the pump, pressurized, compressed contents enters from the opening 4b ₁ provided in the hollow stem 4b on its inner side (Refer FIG. 2), it discharges | emits from the nozzle h of the nozzle n through the cylinder 8b, the small cylinder 8a, and the discharge path | route r.

A piston retainer 9 is fitted and held on the outer side of the cylindrical body 8b of the joint member 8 and regulates the movement of the sliding body 4a of the piston 4. The piston retainer 9 includes a cylindrical body 9a that fits outside the hollow stem 4b and a flange portion 9b that is integrally connected to the end portion of the cylindrical body 9a. When the pressing head 6 is pushed in, the cylindrical body of the piston retainer 9 is formed. 9a is opening 4b ₁ of the hollow stem 4b moves so as to contact the slide 4a is opened, when the press head 6 is in the initial posture in contact with the convex portion 4b ₂ of the sliding body 4a is hollow stem 4b The opening 4b ₁ is closed. Reference numeral 10 denotes an elastic member such as a spring disposed between a base 11 formed outside the cylinder 3 constituting the pump and a flange portion 9b of the piston retainer 9. The elastic member 10 elastically supports the pressing head 6, thereby holding the pressing head 6 in the initial posture and enabling the pressing in the lateral direction.

  A shut-off pin 12 is slidably disposed in the head 6a of the pressing head 6. The shut-off pin 12 is elastically supported via a spring 12a so that the tip thereof closes the nozzle h of the nozzle n. The rear end portion of the shut-off pin 12 is connected to one end of an L-shaped lever 12c that can be pivoted about the pivot pin 12b. When the pressing head 6 is pushed in, the other end of the lever 12c is Pushed by the joint member 8, the lever 12 c rotates about the pivot pin 12 b as a fulcrum and slides the shut-off pin 12 upward (opposite the jet port h) to open the jet port h of the nozzle n. The contents can be discharged.

  When the pressing of the pressing head 6 is released, the force applied to one end of the L-shaped lever 12c is also released, and the pressing head 6 returns to the initial posture by the restoring force of the elastic member 10 (see FIG. 1). In conjunction with this return operation, the shut-off pin 12 slides downward (toward the outlet h) by the repulsive force of the spring 12a and closes the outlet h of the nozzle n.

  The dispenser having the above-described configuration is such that the nozzle outlet h of the nozzle n is opened only when the pressing head 6 is pushed in. Otherwise, the tip of the shut-off pin 12 abuts against the nozzle outlet h of the nozzle n. Therefore, dripping does not occur, and contact with the outside air can be blocked, so that the contents remaining in the discharge path r can be prevented from being easily solidified.

FIG. 2 shows a state in which the pressing head 6 is pushed most. When the pressing force is released from such a state, the pressing head 6 returns to the initial posture due to the repulsive force of the elastic member 10, and the inside of the cylinder 3 becomes negative pressure at that time. The contents are sucked through the passage 5 and the suction port 3a ₁ , and the suction of the contents continues until the pressing head 6 returns to the initial posture.

When the pressing head 6 is pushed in again with the pressing head 6 returned to the initial posture, the content sucked into the cylinder 3 is pressurized and compressed, and the shut-off pin 12 slides upward in conjunction with this, The compressed contents are discharged from the outlet h of the nozzle n through the opening 4b ₁ of the hollow stem 4b, the cylindrical body 8b, the small cylinder 8a, and the discharge path r as shown by the arrows in FIG.

  In order to continuously dispense the contents in the reversing container with such a dispenser, the pressing head 6 may be repeatedly pushed. In addition, when the content can be supplied into the cylinder 3 by its own weight, the content can be continuously discharged by maintaining the pressing state of the pressing head 6. .

FIG. 3 shows another embodiment of a dispenser according to the present invention. 13 in Figure is a valve for closing the suction port 3a ₁ when it moves away from the suction port 3a ₁ opens the suction port 3a _1, pressurized, compressed when sucking the contents. The valve 13 is provided with a rod 13a. The rod 13a is fitted into the internal passage through an opening 4c formed at the end of the hollow stem 4b, and serves as a guide when the piston 4 reciprocates in the cylinder 3. Since it functions, the “blurring” of the piston 4 and the “blur” that tends to occur when the pressing head 6 is pushed in are eliminated, and the operability is improved.

  The dispenser shown in FIG. 3 has a structure in which the joint member 8 is disposed so as to be directly slidable inside the annular peripheral wall 6b of the pressing head 6 (the inner cylinder 7 shown in FIG. 1 is not provided). Can be made compact.

  The dispenser having such a configuration can also discharge the contents in the same manner as described with reference to the dispenser shown in FIG. 1, and in this case as well, the shutoff pin 12 is in a state where the discharge of the contents is stopped. The nozzle n is reliably closed by the tip of the nozzle n, so that no dripping occurs even if the nozzle n is facing downward, and the contents are hardly solidified.
