JP2004105910A - Jetting nozzle for dispenser - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a jetting nozzle which is prevented from floating up from a spin element and jets the contents with a stable spray pattern. <P>SOLUTION: The jetting nozzle has a jetting chip which is set at the tip of a spin element of a dispenser and has an open pore communicating with the pathway of the spin element. In the jetting chip, an inner pipe and an outer pipe are arranged concentrically in a double state and an annular groove is formed between them. Into the annular groove, the tip of the spin element is inserted, and a seal section is formed at each section between the bottom of the annular groove and the outer surface of the inner pipe. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an injection nozzle suitable for use as a dispenser for ejecting the contents sucked and pressurized by a pump in a foamy state, and ensures connection between the injection nozzle and a dispenser body (spin element). The aim is to stabilize the spray pattern.
[0002]
[Prior art]
A dispenser that foams out contents such as mold removers, bleaching agents, and hair styling agents and ejects them is a trigger type that pulls the lever to eject the contents, and a priming type that pushes the pressing head to eject the contents. Are known.
[0003]
Regardless of the type of the spray nozzle attached to the conventional dispenser as described above, the spray nozzle includes a spray tip that engages with the tip of the spin element of the dispenser main body, and the structure is almost common, and Are connected by inserting the tip of the spin element into a groove provided on the back surface of the ejection tip (for example, see Patent Documents 1 and 2).
[0004]
[Patent Document 1]
JP-A-62-42667.
[0005]
[Patent Document 2]
JP-A-60-27484.
[0006]
By the way, in the conventional dispenser, when ejecting the content, a high pressure is applied to the back surface of the ejection tip, so that the ejection nozzle floats away from the spin element, and the content leaks from there, affecting the spray pattern. There was a fear.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to propose a novel injection nozzle that can solve the above-described conventional problems.
[0008]
[Means for Solving the Problems]
The present invention is a nozzle provided with an injection tip having an opening attached to a tip of a spin element of a dispenser and connected to a path of the spin element,
In the injection tip, the inner cylinder and the outer cylinder are arranged concentrically and doublely, and an annular groove is provided between them. The tip of the spin element is inserted into the annular groove, and the groove bottom of the annular groove and the outer surface of the inner cylinder are separated. A spray nozzle for a dispenser, wherein a seal portion is formed in each space therebetween, and this nozzle can be used as a foam generating member by combining a spray tip and a foaming cylinder.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
[0010]
1 and 2 show an embodiment in which the injection nozzle according to the present invention is mounted on a trigger type dispenser (spouter).
[0011]
1 and 2, reference numeral 1 denotes an injection cylinder incorporated in a dispenser main body, 2 denotes a spin element integrally provided at the tip of the injection cylinder, and 3 denotes an injection tip having an opening h connected to a passage 2a of the spin element 2. Reference numeral 4 denotes a foam generating member in which the spray tip 3 is provided, and the foam generating member 4 and the spray tip 3 constitute a spray nozzle.
[0012]
Reference numeral 5 denotes an annular groove formed between the inner cylinder 3a and the outer cylinder 3b of the injection tip 3 in a concentric double arrangement, 6 denotes a lever, 7 denotes a piston engaged with the lever 6, and 8 denotes a piston 7 And 9 is a suction tube for sucking the contents.
[0013]
The injection nozzle having the above configuration can connect the spin elements 2 to each other by inserting the spin elements 2 into the annular groove 5, and at this time, the seal portion S is provided at the groove bottom of the annular groove 5. , becomes the seal portion S ₁ is formed respectively between the outer surface and the inner surface of the spin element 2 of the inner cylinder 3a, even if a higher pressure on the back of the injection tip 3, compared to conventional injection nozzle Since the pressure area received by the spray tip 3 can be reduced, the spray nozzle is easily lifted from the spin element 2 so that the contents do not leak out and the spray pattern is always stabilized.
[0014]
In the embodiment of the present invention, a structure in which the entirety of the spray tip 3 is covered with the foam generating member 4 is described as an example. 4 may be adopted. Further, in the case where the content is ejected in the form of a rod or in the form of a mist, the structure may be such that the foam generating member 4 is removed from the ejection tip 3.
[0015]
【The invention's effect】
According to the present invention, since two seal portions are formed between the ejection tip and the spin element, the ejection nozzle floats up from the spin element when the content is ejected, and the content leaks. It is possible to spray under a stable spray pattern.
