Shokai 57-28760

There is a demand for a so-called two-way type spray container that can be used for spraying by using a long nozzle or by removing the long nozzle depending on the place to be sprayed.
However, when the two-way method is used in Patent Document 1, when the long nozzle is removed from the discharge port, the content liquid may drip from the end of the long nozzle and stain the surroundings. Further, when the content liquid is like an insecticide, the content liquid may adhere to the human body and cause harm.

  An object of the present invention is to propose a spray container with a discharge switching function that can prevent the liquid from falling.

The first means is
A container body 2 in which a stem 8 is erected from the upper surface of the neck portion 6;
A head portion H which is attached to the upper end of the stem 8 and communicates with the stem 8 so as to project the short nozzle 42 forward, which also serves as an operation button;
A long and slender long nozzle 70 protrudes forward from a joint tube portion 56 that is liquid-tightly and detachably fitted to the outer peripheral surface of the short nozzle 42 via an annular diameter-reduced portion 62, and a rotating leg hanging from the joint tube portion 56. In the spray container with a discharge switching function, the lower end of 58 is connected to the front lower portion of the head portion H, and the rotary nozzle portion N is formed so as to be rotatable in the front-rear direction with this connection location as the rotation axis A.
A first check valve V1 disposed in the rotary nozzle portion N is provided on the base end e1 side of the long nozzle 70. The first check valve V1 has a joint cylinder portion 56 with a short nozzle 42. The base end e1 side of the long nozzle 70 is closed with the long nozzle 70 hanging down.

  As shown in FIGS. 1, 5, and 7, this means attaches and detaches the long nozzle 70 with respect to the short nozzle 42 of the head portion H by rotating around the rotation axis A at the lower front surface of the head portion H. A possible structure is proposed. According to this configuration, as indicated by an imaginary line in FIG. 1, the long nozzle 70 is separated from the short nozzle 42 with the base end e1 side facing up, and thus liquid leakage from the base end side is unlikely to occur. Moreover, the 1st check valve V1 is provided in the base end e1 side of the long nozzle 70 by the 1st check valve V1. Thereby, the liquid leakage from a base end and the volatilization of the contents in a long nozzle can be prevented more reliably. Note that “the base end side of the long nozzle” means in the base end of the long nozzle or in the vicinity of the base end.

The second means includes the first means, and the long nozzle 70 is a thin tube with an open tip.

  In this means, as shown in FIG. 1, the long nozzle 70 is a narrow tube with an open tip, and in combination with the proximal end e1 of the long nozzle 70 being closed by the first check valve V1, the long nozzle 70 is made vertical. The liquid is prevented from leaking from the front end side of the long nozzle 70. The inner diameter of the “thin tube” may be appropriately designed so that the liquid does not leak from the tip of the tube wall in consideration of the specific gravity of the contents and the friction between the inner surface of the tube wall and the liquid.

The third means has the first means, and further forms a second check valve V2 on the tip e2 side of the long nozzle 70.

  In this means, as shown in FIGS. 5 and 7, it is proposed to provide a second check valve V <b> 2 on the tip e <b> 2 side of the long nozzle 70. Thereby, the liquid leakage from the front-end | tip e2 side and volatilization of the contents can be controlled.

The fourth means includes the third means, and the valve rod 90 is inserted into the long nozzle 70 so that the long nozzle 70 is urged rearward in a horizontal state, and the valve rod is advanced. Thus, the first check valve V1 and the second check valve V2 are opened, and the first check valve V1 and the second check valve V2 are closed by the retraction of the valve rod 90.

  In this means, as shown in FIG. 7, a valve rod 90 is inserted into the long nozzle 70, and a second check valve V2 and a first check valve V1 are formed at both front and rear portions of the valve rod, respectively. It is configured.

The fifth means includes any one of the first means to the fourth means, and the head portion H includes the head member 30 and the nozzle attachment 40.
The head member 30 is fitted to the stem 8 and protrudes forward through an injection cylinder portion 38 communicating with the stem 8 through the head peripheral wall 36.
The nozzle attachment 40 has a first nozzle hole 46 on the front surface, a cup-shaped short nozzle 42 fitted to the injection cylinder portion 38, and a support leg 52 suspended from the short nozzle 42,
The joint tube portion 56 can be attached to and detached from the short nozzle 42 by connecting the lower end portion of the support leg 52 and the lower end portion of the rotating leg 58 and rotating around the rotation axis A formed at the connecting portion. Is formed.

  As shown in FIG. 1, this means specifically proposes a configuration that enables the joint tube portion 56 to be attached to and detached from the short nozzle 42.

According to the first aspect of the invention, the long long nozzle 70 protrudes forward from the joint cylindrical portion 56 that is liquid-tightly and detachably fitted to the outer peripheral surface of the short nozzle 42 via the annular reduced diameter portion 62. Since the rotary nozzle portion is formed by connecting the lower end of the rotary leg 58 suspended from the joint tube portion 56 to the lower portion of the front surface of the head portion H so that the long nozzle 70 can rotate , the long nozzle 70 projects forward. When the rotary nozzle portion N is rotated so as to shift to the drooping state, liquid leakage from the long nozzle 70 hardly occurs, and the base end e1 side of the long nozzle 70 is disposed in the rotary nozzle portion N. Since the 1st check valve V1 arrange | positioned in this is formed, the liquid leakage from the base end side of the long nozzle 70 and volatilization of the contents can be prevented.
According to the second aspect of the invention, since the proximal end side of the long nozzle 70, which is the thin tube, is closed by the first check valve V1, it is difficult for liquid leakage to occur from the distal end side even when the long nozzle 70 is in a vertical state. .
According to the third aspect of the invention, since the second check valve V2 is further formed on the tip e2 side of the long nozzle 70, liquid leakage and volatilization of the contents are caused from the tip side even when the long nozzle 70 is in a vertical state. Does not occur.
According to the fourth aspect of the invention, since the first check valve V1 and the second check valve V2 are opened and closed by the longitudinal movement of the valve rod 90, the opening and closing operation of the valve can be reliably performed.
According to the fifth aspect of the invention, the support leg 52 suspended from the joint tube portion 56 and the lower end of the rotary leg 58 suspended from the short nozzle 42 are connected, and the rotation axis A formed at the connection location is the center. Since the joint cylinder portion 56 is formed so as to be attachable to and detachable from the short nozzle 42 by rotation, a smooth operation is possible.

1 to 4 show a spray container with a discharge switching function according to a first embodiment of the present invention. This spray container is formed by the container body 2, the mounting member 10, the head member 30, the nozzle attachment 40 and the joint 54, and the long nozzle 70. The mounting member 10, the head member 30, the nozzle attachment 40 and the joint 54, and the long nozzle 70 can be formed entirely or partially from a synthetic resin material.
In the present specification, for convenience, a portion that rotates together with the long nozzle in the structure other than the container body is referred to as a rotary nozzle portion N, and a portion that does not rotate (nozzle attachment 40 and head member 30). (The portion consisting of) is referred to as a head portion H (see FIG. 1).

  In this embodiment, the container body 2 is configured as an aerosol container body. The aerosol container body generally has a stem 8 erected from a neck portion 6 that is continuous with the body portion 4, and is provided so that the aerosol is discharged from the stem 8 by pressing or tilting the stem 8. However, the container body is not necessarily limited to the aerosol container body.

  The mounting member 10 hangs down the outer peripheral wall 16 from the upper end of the mounting cylinder portion 12 fitted to the neck portion 6 via the outward flange-shaped top wall portion 14 and bulges the left and right sides of the top wall portion 14. Thus, as shown in FIG. 2, a pair of raised portions 18 for protecting the head member are formed. As shown in FIG. 1, a recessed portion 20 is formed in the front portion of the top wall portion 14, and a longitudinal groove portion 22 extending downward from the front end portion of the recessed portion 20 is formed. The reason why the vertical groove portion 22 and the recessed portion 20 are provided is that the long nozzle 70 and the joint cylinder portion 56 are attached to the mounting member 10 when a long nozzle 70 described later is rotated to a vertical state as indicated by an imaginary line in FIG. This is to prevent collisions.

  The head member 30 is attached to the stem 8 and also serves as an operation button. The illustrated head member 30 hangs down the fitting cylindrical portion 34 from the center portion of the top plate portion 32 and the head peripheral wall 36 from the outer peripheral portion of the top plate portion 32, and penetrates the head peripheral wall 36 from the fitting cylindrical portion 34. Thus, the injection cylinder portion 38 protrudes forward. The fitting cylinder portion 34 is fitted to the stem 8. A core rod portion 39 is supported inside the fitting tube portion 34 via a connecting piece 39a. A flange portion 38 a is attached to the front outer surface of the fitting tube portion 34.

  The nozzle attachment 40 is an accessory of the head member 30 and includes a short nozzle 42. The nozzle attachment 40 has a fitting tube portion 50 and support legs 52.

  The fitting cylinder part 50 is fitted to the front part of the injection cylinder part 38. As shown in FIG. 3, the front surface of the fitting tube portion 50 is closed by the front wall portion 44, and the fitting tube portion 45 that protrudes rearward from the rear surface of the front wall portion 44 is replaced with the injection tube portion 38 and the core rod portion 39. It is loosely fitted between. A first nozzle hole 46 is formed in the front wall portion inside the fitting tube portion 50. A tapered shallow recess is formed on the front surface of the front wall around the first nozzle hole 46. In a preferred illustrated example, a portion between the tube wall of the fitting tube portion 50 and the front wall portion 44 is formed in a tapered portion 48 whose outer surface is rounded and chamfered.

  In the present embodiment, nothing is provided in the gap S between the front end of the core bar portion 39 and the front wall portion 44, but a spin mechanism may be provided if necessary. If the container body is not an aerosol container, the liquid can now be spun into a mist. Further, when the container body is an aerosol container body, a finer mist can be obtained by using the spin mechanism. In addition, by adding technical means such as a mesh to other places in the gap or flow path, or by changing the nozzle tip, it is possible to appropriately adjust the foaming form, the mist form, or the straight form of the contents. .

  The support leg 52 extends downward from the rear end portion of the fitting tube portion 50. The illustrated support leg 52 is a flat plate having a certain width in the left-right direction, and its rear surface is in contact with the flange-shaped portion 38a.

  The joint 54 protrudes forward from the joint tube portion 56 fitted to the tube wall of the fitting tube portion 50 via the annular reduced diameter portion 62 and rotates from the rear portion of the joint tube portion 56. The leg 58 is suspended. The inner surface of the annular reduced diameter portion 62 is a gently curved surface corresponding to the outer surface of the tapered portion 48. A first valve seat 66 that is a stepped portion facing forward is provided around the rear end portion of the connecting cylinder portion 64.

  The rotary leg 58 preferably has a vertical flat plate shape that overlaps the support leg 52. The lower end portion of the rotating leg 58 and the lower end portion of the support leg 52 are connected by a thin hinge 60, and the joint 54 is formed to be rotatable around a rotation axis A formed at this connecting portion. By this rotation, the joint cylinder part 56 can be attached to and detached from the short nozzle 42.

  In the present embodiment, the joint 54 and the nozzle attachment 40 are integrally formed, but it is not always necessary to do so. When the joint 54 and the nozzle attachment 40 are formed of a soft material, the joint tube portion 56 can be easily attached to and detached from the short nozzle 42.

  The long nozzle 70 protrudes forward from a base end e1 fixed to the joint 54. In the present embodiment, the tip e2 of the long nozzle 70 is an open end. The illustrated long nozzle 70 is formed of a nozzle tube 74 that is a long thin tube in the front-rear direction and a tubular connecting member 72. The tubular connecting member 72 is formed by connecting a rear end portion of a cylindrical wall to a first valve body 73 that can be expanded and contracted in the front-rear direction. A through hole 72a is formed at the rear end of the cylindrical wall.

  An elastic ring body is provided at an intermediate portion of the first valve body 73. A hook-like protrusion is attached to the rear outer surface of the first valve body 73, and this protrusion abuts against the first valve seat 66 to form the first check valve V <b> 1. The long nozzle 70 and the joint 54 form the rotary nozzle portion N described above.

  In the above configuration, when spraying using the long nozzle 70, the head member 30 may be pushed down from the state shown in FIG. Then, the aerosol sprayed from the stem 8 passes through the injection cylinder portion 38, the first check valve V1 opens, and the aerosol passes through the joint 54 and the nozzle pipe 74 from the first nozzle hole 46 as shown by the arrow in FIG. It is ejected from the tip e2 of the long nozzle 70.

  Next, when spraying using the short nozzle 42, the long nozzle 70 is gripped and pulled downward. Then, the joint cylinder part 56 is detached from the short nozzle 42, the long nozzle 70 rotates around the rotation axis A, and moves to a position drawn by an imaginary line in FIG. In the present embodiment, since the first check valve V1 is closed, the liquid in the flow path downstream from the first check valve V1 does not spill from the base end side of the long nozzle 70, and the long nozzle 70 The liquid does not volatilize from the base end side. Also, the liquid in the flow path between the first check valve V1 and the first nozzle hole does not leak downward because the rear opening of the joint cylinder portion 56 faces upward. Furthermore, since the nozzle tube 74 is a thin tube, the first check valve V1 is closed, so that it does not lean from the tip e2 side.

  Other embodiments of the present invention will be described below. In these descriptions, the description of the same structure as that of the first embodiment is omitted.
