Description

  The present invention relates to a discharge container with an extension nozzle.

A discharge container in which a nozzle cylinder protrudes laterally outward from the side surface of the nozzle head standing from the container body is well known, but it is inconvenient if the contents hang from the tip of the nozzle cylinder and adhere to the container body. However, when the protruding length of the nozzle cylinder is increased, there arises a problem that the nozzle cylinder is bulky when the product is distributed.
Thus, an extension nozzle is prepared as a separate body from the discharge container with a nozzle cylinder, and is fitted to the tip of the nozzle cylinder when the container is used (Patent Document 1).

JP 2010-105720 A

In the discharge container with an extension nozzle of Patent Document 1, when another object unexpectedly touches the extension nozzle during use, the extension nozzle may drop from the nozzle cylinder of the nozzle head.
In order to avoid this, the inner diameter of the base end of the extension nozzle should be designed to be tight with respect to the outer diameter of the tip of the nozzle cylinder so that the extension nozzle is securely fitted to the tip of the nozzle cylinder. However, in this case, when the extension nozzles are removed from the nozzle head and they are to be cleaned, they cannot be easily removed, which is inconvenient.

  One object of the present invention is to prevent the extension nozzle from unexpectedly falling out of the nozzle cylinder of the nozzle head in a discharge container with an extension nozzle, and another object is to extend the nozzle for cleaning. When trying to remove the nozzle from the nozzle head, the removal operation can be easily performed.

  1 to 5 show a discharge container with an extended nozzle according to the first embodiment of the present invention. This discharge container is composed of a main member 1, an extension nozzle 14 and an adapter 30. Each of these members can be formed of synthetic resin or metal.

The main member 1 has a conventionally known configuration, and is configured as a discharge container having a built-in pump mechanism in the present embodiment. However, as described above, this structure can be appropriately changed. The main member 1 in the illustrated example includes a container body 2, a pump cylinder (not shown), a mounting cap 4, an auxiliary cap 6, and an operating member 8.
The container body 2 stands up from an unillustrated mouth and neck from the trunk.
The mounting cap 4 projects an inward flange 4b inwardly from the upper end of the mounting cylinder 4a fitted to the outer surface of the mouth and neck.
The pump cylinder has a flange-like flange portion attached to the upper end of the cylinder peripheral wall, and is supported in the container body 2 by sandwiching the flange portion between the mouth-and-neck portion and the inward flange 4b. . A liquid suction pipe is suspended from the lower part of the pump cylinder, and a first check valve is provided at the lower part of the pump cylinder.
The auxiliary cap 6 is a means for preventing the actuating member 8 from coming off. The lower half of the cap peripheral wall is fitted into the upper part of the pump cylinder, and a screw portion is formed on the outer surface of the upper half. The outward flange 6a protrudes outward from the portion.
The actuating member 8 has a cylindrical piston that slides on the inner surface of the pump cylinder at the lower portion, and is provided with a nozzle head 12 at the upper end of the stem 10 that stands up from the auxiliary cap 6. The nozzle head 12 hangs a mounting cylinder (not shown) that is preferably detachably attached to the stem from the center of the back surface of the head top wall 12a, and has a large-diameter head peripheral wall 12b from the outer periphery of the head top wall 12a. In addition, the auxiliary peripheral wall 12c having a small diameter is suspended. In the illustrated example, the auxiliary peripheral wall 12c is formed so as to be screwable with the upper half of the cap peripheral wall of the auxiliary cap 6. From the front surface of the head peripheral wall 12b, a nozzle cylinder 12d communicating with the stem 10 is projected forward.
In this specification, for the sake of convenience, the left side of FIG. 2 (the direction in which the nozzle cylinder protrudes) is referred to as “front”, and the right side of FIG.
A second check valve (not shown) is formed inside the operation member 8, and the liquid in the container body 2 is passed through the first check valve by raising and lowering the operation member 8 with respect to the container body 2. The pump cylinder is sucked into the pump cylinder, and the liquid in the pump cylinder is discharged from the nozzle cylinder 12d to the outside via the second check valve. The contents of the container are not limited to liquid.

As shown in FIG. 2, the extension nozzle 14 is formed by fitting the base end E1 side of the extension nozzle 14 to the tip end side of the nozzle cylinder 12d, and has a role of extending the discharge channel of the contents. The extension nozzle 14 of the present embodiment has at least a tube wall 16 and an engaging protrusion 22 attached near the proximal end of the tube wall 16.
In the illustrated example, the tube wall 16 has a bent portion 18 in the middle portion in the longitudinal direction, is inclined forward and downward from the bent portion 18 on the proximal end E1 side, and hangs vertically from the bent portion 18 on the distal end E2 side. . However, these structures can be changed as appropriate.
In the present embodiment, the diameter of the base portion of the tube wall 16 (referring to the tube wall portion in the vicinity of the base end E1) is increased through a step S from the tube wall portion other than the base portion as indicated by a dotted line in FIG. The inner diameter portion 20 is formed. When the extension nozzle 14 is fitted to the tip of the nozzle cylinder 12d, the extension nozzle 14 may be fitted until the tip hits the step S. As a result, the engagement protrusion 22 of the extension nozzle 14 can be positioned with respect to the nozzle cylinder 12d and the head cover 32, and the engagement length of the extension nozzle 14 to the nozzle cylinder 12d is insufficient. The problem that the portion 42 cannot be locked to the engaging protrusion 22 is eliminated.
The engaging protrusion 22 has an engaging end surface 22a on the side close to the tip E2 of the tube wall 16, and is formed so that a locking portion 42 described later can be locked to the engaging end surface. The engagement protrusion 22 in the illustrated example is formed as an engagement flange, but may have any structure as long as the engagement portion 42 can be engaged. In the illustrated example, the engaging protrusion 22 is provided closest to the base end E1 of the large inner diameter portion 20, but the arrangement thereof can be changed as appropriate.

  The adapter 30 is a jig that assists in attaching the extension nozzle, and includes a head cover 32, a connecting arm 40, and a locking portion 42. In the illustrated example, these are integrally formed.

The head cover 32 has a top plate 33 having a diameter larger than that of the nozzle head 12, and a large-diameter operation tube portion 34 having a short foot and a small-diameter fitting tube portion 36 having a long foot from the outer peripheral portion of the top plate 33. It is suspended in the shape of a heavy cylinder, and a pressing cylinder part 38 is suspended from the center part of the top plate 33.
The fitting cylinder portion 36 is fitted to the outer surface of the head peripheral wall 12 b of the nozzle head 12. A notch 36a is formed in the front part of the cylinder wall of the fitting cylinder part 36, and the nozzle cylinder 12d is formed so as to be inserted into the notch 36a when fitted to the head peripheral wall 12b. . An engagement rib 36b that can be engaged with the lower end surface of the head peripheral wall 12b is attached to the inner surface of the lower end portion of the fitting cylinder portion 36.
The operation cylinder portion 34 is means for pulling up the head cover 32 by placing a finger on the lower surface thereof. In the illustrated example, the front wall portion of the operation tube portion 34 is opened, and the connecting arm 40 extends forward from the opening location.
The pressing cylinder part 38 is configured such that the lower end of the cylinder wall of the pressing cylinder part comes into contact with the upper surface of the head top wall 12a of the nozzle head 12 with the fitting cylinder part 36 fitted to the head peripheral wall 12b. Is formed.

The connecting arm 40 protrudes forward from the front portion of the operation tube portion 34 along the nozzle tube 12d. The term “follow” does not mean that the connecting arm 40 is in close contact with the outer surface of the nozzle cylinder 12d. In the illustrated example, there is a gap between the connecting arm 40 and the nozzle cylinder 12d. To do.
Further, in the preferred illustrated example, the connecting arm 40 is formed in a bent plate portion having an inverted U-shaped cross section when viewed from the projecting direction. This increases the rigidity of the connecting arm 40. The adapter 30 including the connecting arm 40 can be formed of a flexible material. In this specification, the U shape includes an arc shape, for example, a shape in which the lower side is shallow and recessed.

The locking portion 42 protrudes from the tip portion 40 a of the connection arm 40 to the inside of the connection arm 40 so as to be locked to the engagement end surface 22 a of the engagement protrusion 22.
The locking portion in the illustrated example is formed in an arc-shaped locking plate portion that protrudes inward from the entire tip of the bent plate portion that is a connecting arm, and has a nozzle insertion port 44A through which the nozzle cylinder can be inserted from below. Have. However, the shape of the locking portion 42 can be changed as appropriate, and for example, a protrusion protruding inwardly from a part of the tip of the connecting arm 40 may be used.
In the present specification, the “arc-shaped locking plate portion” is a term used to distinguish from the ring-shaped locking plate portion of the second embodiment, and does not need to be an arc.

In the above configuration, when the extension nozzle 14 and the adapter 30 are assembled to the main member 1, the base end E1 side of the extension nozzle 14 is fitted to the nozzle cylinder 12d of the nozzle head 12 from the state shown in FIG. The user can understand that the nozzle cylinder 12d is fully inserted by the tactile sensation when the tip of the nozzle cylinder 12d hits the step S in the extension nozzle 14. In this state, the engaging portion 4 of the adapter 30 is engaged with the engaging end surface 22 a of the engaging protrusion 22 of the extension nozzle 14.
When the head cover 32 is pushed down from the state indicated by the imaginary line in FIG. 2, the nozzle head 12 can be fitted to the outer surface as shown by the solid line in FIG. When the adapter 30 is formed of a flexible material, the connecting arm 40 is bent and the fitting cylinder portion 36 provided with the notches 36a is easily expanded, so that the fitting operation becomes smoother.
Since the locking portion 42 of the adapter 30 is locked to the engagement protrusion 22 of the extension nozzle 14 in the state of FIG. 2, it is possible to prevent the extension nozzle 14 from dropping off unexpectedly. When the top plate 33 of the head cover 32 is pushed down in this state, the nozzle head 12 is pushed down via the pushing cylinder portion 38, and the liquid in the pump cylinder is discharged from the extension nozzle 14 via the nozzle cylinder 12d.
When the extension nozzle 14 is cleaned after use, it is preferable that the operation tube portion 34 is lifted by placing a finger on the rear wall portion from the state shown in FIG. Since the rear wall portion is located behind the fitting cylinder portion 36, that is, far from the engagement portion 42, the rear wall portion of the operation cylinder portion 34 is a force point, the engagement portion 42 is a fulcrum, and the nozzle head. 12, the engaging rib 36b of the fitting cylinder part 36 is easily detached from the lower end of the head peripheral wall 12b.
After the head cover 32 is removed from the nozzle head 12, the extension nozzle 14 can be removed from the nozzle cylinder 12d. Thereby, the extension nozzle 14 can be easily cleaned. Of course, the nozzle head 12 can also be removed from the stem 10 and cleaned.
