Description

The present invention relates to an inserter that is mounted on the tip of a ejection nozzle tube having a hollow flow path through which a fluid flows and can change the ejection amount.

In the structure of sprays and aerosols, in addition to the contents, liquefied gas such as LPG and butane for ejecting the contents and gas such as nitrogen, carbon dioxide and air are sealed in the spray can and aerosol can, and above the can. The structure is such that the contents in the can are ejected by using the provided ejection nozzle or an opening provided at the tip of the nozzle tube by further attaching a nozzle tube to the ejection nozzle as an ejection port.

When the contents are ejected in a spray can or an aerosol can, the contents and the gas are alternately ejected in a separated state, and as a result, the contents are ejected intermittently, resulting in stable ejection. There was a problem that it was not broken. In addition, regarding the amount of content ejected, it is ejected at a strong pressure at the beginning, but the ejection amount suddenly weakens as the gas pressure decreases with the passage of time, and as a result, the ejection amount at the initial stage and the final stage of the ejection. There was also the problem that was not constant.

Therefore, the applicant has developed a technique for reliably stirring the fluid (liquid and gas) in the flow path tube and mixing them evenly and uniformly, and has made a technical proposal described in Japanese Patent No. 5924655 (Patent Document 1). There is. According to such a technical proposal, by inserting and arranging a porous material having a continuous pore structure in the pipeline of the flow path pipe, the fluid (liquid and gas) flowing in the pipeline is surely stirred and evenly and uniformly. It is mixed and the outflow of foreign matter can be prevented by the filter effect of the porous material, and the flow rate can be adjusted by the length, pores and porosity (porosity) of the porous material. It had an excellent effect.

However, according to the technical proposal according to Patent Document 1, although the effect of inserting the porous material is useful, the hard porous material used as the material is expensive, and the soft porous material is inexpensive. When the above is used, the insertion work is more difficult than that of the hard one, and there is a new problem that the desired performance may not be exhibited depending on the insertion situation. Therefore, in the ejection nozzle tube, a technique capable of adjusting the ejection amount more easily has been required.

The applicant has focused on the problem that it is difficult to adjust the ejection amount of fluid (liquid and gas) in the conventional spray cans and aerosol cans as described above, and the ejection nozzle that can adjust the ejection amount more easily. Based on the idea of being able to provide a tube, we have developed an inserter that can easily adjust the amount of ejection and also exert a fluid stirring action by equipping it at the tip of the ejection nozzle tube. This leads to the proposal of the "insertion tool for a ejection nozzle tube" according to the invention.

Japanese Patent No. 5924655

In view of the above problems, it is an object of the present invention to provide an inserter equipped at the tip of a ejection nozzle tube and capable of easily adjusting the ejection amount.

In order to solve the above problem, the present invention is an inserter capable of adjusting the amount of fluid ejected from the ejection nozzle pipe, and has a required length and diameter width that can be inserted into the conduit from the tip of the ejection nozzle pipe.

Hereinafter, an embodiment of the fitting 1 for a ejection nozzle tube according to the present invention will be described with reference to the drawings.

The fitting 1 for a ejection nozzle tube according to the present invention is not particularly limited to the embodiments described below, and is within the scope of the technical idea of the present invention, that is, a shape and dimensions capable of exhibiting the same action and effect. , The material can be changed as appropriate.

It shows the usage mode when it is used.
The fitting 1 for a ejection nozzle tube according to the present invention is mounted on the tip of the ejection nozzle tube 2, and is composed of a core material 10 and a head portion 20.

The ejection nozzle tube 2 is provided with a pipeline 3 penetrating in the longitudinal direction, the base end is connected to a valve body provided at the upper end of a spray can or an aerosol can, and the tip functions as an ejection port. It is a flow path pipe for ejecting the contents of the or aerosol can from the tip through the pipe line 3.
The material of the ejection nozzle tube 2 is not particularly limited, such as made of metal or synthetic resin, and various materials can be adopted, for example, LDPE (low density polyethylene, HDPE (high density polyethylene)). , Fluorine resin, polyamide synthetic fiber, polypropylene, PEEK (polyetheretherketone) and the like.

The ejection nozzle tube fitting 1 (hereinafter, may be simply referred to as “inserting tool”) is mounted on the tip of the ejection nozzle tube 2 and is inserted into the conduit 3 of the ejection nozzle tube 2. It is composed of a core material 10 to be fitted and a head portion 20 provided at one end of the core material 10 and capable of contacting the tip of the ejection nozzle tube 2.
The material of the insert 1 is not particularly limited, but an embodiment made of an easily processable material such as metal or synthetic resin is preferable. For example, by making it made of synthetic resin, by contacting the heated heating wire, a slit having a diameter of the heating wire can be easily formed on the outer peripheral surface of the core material 10, which contributes to the improvement of workability. ..
By the way, regarding the material of the inserter 1, in addition to the mode in which the core material 10 and the head portion 20 are molded from the same material, a mode in which the core material 10 and the head portion 20 are molded from different materials can be considered. Further, in addition to the embodiment in which the core material 10 and the head portion 20 are integrally molded from the same material, they are separately molded from the same material or different materials and integrated by any joining means such as adhesion or fusion. Aspects are also possible.

The core material 10 is a rod-shaped body having a predetermined length and a required diameter width that can be inserted into the pipe line 3 of the ejection nozzle pipe 2. By inserting the core material 10 into the pipe line 3 from the tip of the ejection nozzle pipe 2, a slight gap between the outer peripheral surface of the core material 10 and the inner peripheral surface of the pipe line 3 becomes a flow path of the fluid R. It will function as 11. The length of the core material 10 is not particularly limited, but the length of the flow path 11 is determined by the length of the core material 10, and the length of the flow path 11 is the stirring of the fluid R flowing therethrough. -It affects the uniform mixing action, and is formed, for example, having a length 3 to 10 times the inner diameter of the pipeline 3. The diameter width of the core material 10 is a diameter width that can be inserted into the pipe line 3 of the ejection nozzle pipe 2, and at least a part of the outer peripheral surface of the core material 10 abuts on the inner peripheral surface of the pipe line 3. , It is necessary to have a diameter width that does not fall out of the pipeline 3 in the inserted state even if it receives the pressure of the fluid R, that is, the diameter width is substantially the same as or slightly reduced from the inner diameter of the pipeline 3. There is.

The end-view shape of the rod-shaped core material 10 is formed into a circular shape as shown in FIG.

Since the end face view shape of the core material 10 is circular , the outer peripheral surface of the core material 10 and the inner peripheral surface of the pipeline 3 are completely in close contact with each other depending on the diameter width, and no gap is formed. Therefore, the flow path 11 is formed. It is also assumed that the fluid R does not flow. Therefore, as shown in FIG. 3, it is conceivable that the flow path 11 is formed in advance on the outer peripheral surface of the core material 10. The flow path 11 forms a concave groove 12 on the outer peripheral surface of the core material 10 as shown in FIG. 3A, or the projecting piece 13 projecting from the outer peripheral surface as shown in FIG. 3B. Is formed by forming. As the form of the flow path 11, various forms such as a linear shape, a curved shape, a spiral shape, and a bent shape can be considered.
When a form other than the linear shape is adopted as the form of the flow path 11, the flow path 11 longer than the insertion length of the core material 10 is formed, that is, it is desirable even if the core material 10 is shortened. It becomes possible to secure a flow path 11 having a length, which contributes to reduction of material cost, uniform fluid pressure, and uniform stirring / mixing of fluid R.

In the core material 10, in order to prevent the inserted core material 10 from coming off from the pipeline 3, it is also preferable to perform a retaining process 14 at a predetermined position on the outer peripheral surface. The specific structure of the retaining process 14 is not particularly limited. For example, the outer peripheral surface of the core material 10 is subjected to a file-like uneven processing having a high friction coefficient, or a ejection nozzle tube as shown in FIG. It is conceivable that a mode of forming one or a plurality of file portions that makes it difficult to proceed in the direction of the tip of 2. As a result, even when a high fluid pressure is applied, it is possible to reliably prevent the core material 10 from falling out of the pipeline 3, which contributes to stable fluid ejection.

The head portion 20 is provided at one end of the core material 10, is formed of a substantially circular or polygonal plate-like body having a predetermined thickness as shown in the figure, and is formed to have a diameter larger than the inner diameter of the pipeline 3 at least. .. That is, even when the core material 10 is inserted into the pipe line 3, the head portion 20 does not enter the pipe line 3 and stays outside the tip of the ejection nozzle pipe 2. When the head portion 20 stays outside the tip of the ejection nozzle tube 2, the gap space between the tip of the ejection nozzle tube 2 and the head portion 20 functions as an ejection port, and the fluid R flowing through the conduit 3 functions as an ejection nozzle. When the tube 2 is ejected forward from the tip, the tube 2 abuts against the head portion 20 and is ejected in a circumferential direction (see FIG. 7A). Further, the distance between the tip of the ejection nozzle tube 2 and the head portion 20 is changed according to the insertion length of the core material 10, and such an interval acts as a function of adjusting the ejection amount of the fluid R. .. The diameter width of the head portion 20 is not particularly limited except that the diameter is larger than the inner diameter of the pipeline 3, but the diameter width is substantially the same as or slightly reduced from the inner diameter of the pipeline 3.

By the way, when the head portion 20 is completely brought into contact with the tip of the ejection nozzle tube 2 when the core material 10 is inserted, the tip of the ejection nozzle tube 2 and the head portion 20 are completely in close contact with each other to form a gap. However, it is assumed that it will not function as a spout. Therefore, as shown in FIG. 5, it is conceivable that a gap 21 is formed in advance on the contact surface of the head portion 20 with the tip of the ejection nozzle tube 2. The gap 21 forms a concave groove 22 on the contact surface with the tip of the ejection nozzle tube 2 in the head portion 20 as shown in FIG. 5A, or as shown in FIG. 5B. It is formed by forming a projecting piece 23 protruding from the contact surface. Regarding the form of the gap 21, a radial, linear or curved form can be considered in view of the fluid ejection in the circumferential direction. Further, regarding the number, direction, and width of the gaps 21 to be formed, the ejection direction, the ejection amount, and the like are taken into consideration, and if necessary, one or more gaps 21 have a required width in an arbitrary direction. It is molded and is not particularly limited.

Regarding the form of the head portion 20, as shown in FIG. 6, it is conceivable to form an inclined notch portion 24 that expands forward on the contact surface with the tip of the ejection nozzle tube 2. By adopting such an embodiment, it is possible not only to eject the fluid in a direction substantially perpendicular to the traveling direction of the fluid R in the ejection nozzle tube 2, but also to eject the fluid diagonally forward through the notch 24 (FIG. 7 (FIG. 7). b) See). The portion of the head portion 20 where the notch portion 24 is formed is a contact surface with the tip of the ejection nozzle tube 2, and the entire portion is circumferentially inclined to form a horn-shaped notch portion 24. It is also possible to partially incline one or more points.

The ejection nozzle tube fitting 1 according to the present invention is configured by each of the above components. The fitting 1 according to the present invention can be attached by a simple operation such as inserting the core material 10 into the pipe line 3 from the tip of the ejection nozzle pipe 2 connected to the spray can or the aerosol can. Then, in such mounting, the ejection amount of the fluid R can be adjusted by adjusting the distance between the tip of the ejection nozzle tube 2 and the head portion 20.

The usage mode of the ejection nozzle tube 2 equipped with the fitting 1 according to the present invention will be described below.
When a spray can or an aerosol can filled with the fluid R (contents and gas) is operated, the fluid R is alternately ejected in a state where the contents and the gas are separated, and the pipeline of the connected ejection nozzle pipe 2 is ejected. 3 is similarly separated and proceeds to reach the fitting 1 provided at the tip of the ejection nozzle tube 2.
The fluid R that has reached the insert 1 further proceeds while flowing into the flow path 11 formed by the gap between the outer peripheral surface of the core material 10 and the inner peripheral surface of the pipeline 3. At this time, the separated contents and the gas are agitated and uniformly mixed by the flow path 11 narrowed from the pipeline 3.
The fluid R that has passed through the flow path 11 is ejected forward from the tip of the ejection nozzle tube 2.
As shown in FIG. 7, the fluid R ejected forward abuts on the head portion 20 existing outside the tip of the ejection nozzle tube 2 and changes its direction from the front to the circumferential direction, and the tip and the head portion of the ejection nozzle tube 2 It will be ejected from the gap with 20.

Although the basic configuration mode and operation of the insertion tool 1 for the ejection nozzle tube according to the present invention have been described above, the present invention is not limited to the configuration mode shown in the above embodiment or the drawings. For example, the shape of the core material 10 may be a substantially conical shape in which the diameter is gradually reduced from the head portion 20 side to the insertion side.

As described above, according to the insertion tool 1 for the ejection nozzle tube according to the present invention, the fluid R that can be easily attached to the tip of the ejection nozzle tube 2 and flows into the ejection nozzle tube 2 from the spray can or the aerosol can is the core material 10. By passing through the flow path 11 formed in the gap between the fluid R and the pipeline 3, the fluid R is stirred and mixed to stably eject the contents, depending on the insertion length of the core material 10. The distance between the tip of the ejection nozzle tube 2 and the head portion 20 is variable, and the desired fluid R ejection amount can be easily adjusted.

The present invention can be attached to the tip of any nozzle tube, not just the ejection nozzle tube connected to a spray can or aerosol can. Therefore, it is considered that the industrial applicability of the "insertion tool for the ejection nozzle tube" according to the present invention is great.
