JP4248907B2 - Injection nozzle for former dispenser - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an injection nozzle suitable for use in a former dispenser that sucks and pressurizes the contents in a container by a pump mechanism and jets the contents in a foam state. It is intended to switch and change without touching the remaining contents.
[0002]
[Prior art]
Former dispensers that foam and blow out contents such as wiping agent, bleach, facial cleanser, hair conditioner, etc., discharge the contents ejected from the opening of the nozzle body into the nozzle opening. A foam-forming nozzle tip that is made to foam by colliding with a barrier placed near the side is attached, and is the bubble ejection pattern (foaming state) removed from the tip opening to make it open? Switching is performed by matching the front end opening to a closed state (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 9-285746
By the way, the conventional injection nozzle attached to the former dispenser is provided with a gripping portion at the lower end portion of the tip when the nozzle tip is opened and closed, and has the gripping portion to change the bubble pattern. When opening and closing the nozzle tip, there is a problem that the tip of the injection nozzle and the contents remaining in the nozzle may flow out of the opening of the tip and adhere to the hand.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to propose a new spray nozzle for a former dispenser that can switch and change the foam spray pattern without touching the residual contents.
[0006]
[Means for Solving the Problems]
The present invention is an injection nozzle that ejects the content pumped through the injection cylinder of the former dispenser toward the outside,
A nozzle body that is mounted at the tip of the injection cylinder and has an opening connected to the passage of the injection cylinder, and a closed posture that is swingably held along the open end of the nozzle body and is aligned with the open end An injection nozzle for a former dispenser comprising a nozzle tip that discharges the contents ejected from the opening in the form of foam to the outside, and a gripping portion is provided in a region excluding the lower end portion of the nozzle tip. is there. The nozzle body can be provided with a stopper member that extends from the nozzle body side and matches the gripping portion in the closed posture to restrict the nozzle chip from swinging downward.
[0008]
Further, the nozzle tip may be swung by a pivot or a hinge.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 and 2 show an embodiment of an injection nozzle according to the present invention. FIG. 1 shows a state in which creamy bubbles can be ejected in a closed posture in which a nozzle tip is matched with an open end of a nozzle body. FIG. 2 shows a state in which the nozzle tip can be ejected in the form of a relatively coarse bubble or mist as an open posture with the nozzle tip removed from the open end of the nozzle body.
[0010]
1 and 2, reference numeral 1 denotes a nozzle body attached to the tip of an injection cylinder (not shown) of the former dispenser. The nozzle body 1 has an opening 1a connected to the passage of the injection cylinder as shown in FIG. is doing.
[0011]
Reference numeral 2 denotes a nozzle tip which is held by the nozzle body 1 through a pivot pin P so as to be swingable. The nozzle tip 2 has a barrier 2a for causing the contents ejected from the opening 1a to collide and foam, and the contents are foamed in a closed position as shown in FIG. Can be discharged.
[0012]
Reference numeral 3 denotes a grip portion which is provided integrally with the nozzle tip 2 and protrudes laterally from the side wall when the nozzle tip 2 is closed, and the grip portion 3 extends from the nozzle body 1 side in the closed posture. It has a shape that matches the notch of the stopper member (only part of which is shown).
[0013]
The injection nozzle according to the present invention can hold the gripping portion 3 protruding from the side wall of the nozzle tip 2 when switching and changing the foam ejection pattern, so that the nozzle tip 2 can be in the open posture and the closed posture. The contents remaining on the tip or inside thereof do not adhere to the hand.
[0014]
FIG. 3 shows the ejection pattern of the contents of the nozzle chip 2 in an open position by providing a grip portion 3 on the upper part of the side wall of the nozzle chip 2 and guiding the swinging downward with the pivot pin P as a fulcrum. FIG. 4 shows another embodiment for switching and changing. FIG. 4 is similar to FIG. 1, and the nozzle body is provided with the holding pin 3 in the lateral direction of the side wall of the nozzle tip 2 and the pivot pin P as a fulcrum. 1 shows a reference technique according to the present invention in which the nozzle tip 2 is opened to change and change the ejection pattern of contents by swinging upward so as to be separated from the open end of 1.
[0015]
Figure 3, also those shown in FIG. 4, the gripping portion 3 is provided in a region except for the lower end of the nozzle tip 2, switching of the jet pattern, no residual contents were when the change touches the hand .
[0016]
The nozzle tip 2 is of a type that swings along the open end of the nozzle body 1 as shown in FIGS. 1 and 3, or swings away from the open end of the nozzle body 1 as shown in FIG. The type to be selected is appropriately selected depending on the size and shape of the nozzle body 1.
[0017]
One of the nozzle tip 2 and the nozzle body 1 is provided with a convex portion, and the other is provided with a concave portion that engages with the convex portion or a second convex portion that can be crossed over, so that the nozzle tip 2 is in an open posture or a closed posture. Sometimes the convex part is engaged with the concave part or over the second convex part, and the nozzle chip 2 is fixed to the nozzle body 1 and positioned so as to suppress unintentional oscillation of the nozzle chip 2. Although not shown, it may be coupled to the nozzle body, and this point is not particularly limited.
[0018]
In any of the embodiments shown in FIGS. 1 to 3 and the reference technique shown in FIG. 4, in order to foam the contents, air is taken in from the outside between the opening 1 a and the barrier 2 a. It is indispensable to mix the contents ejected from 1a and air, and for that purpose, as shown in FIG. 5, a passage surrounding the periphery of the barrier 2a and communicating between the aperture 1a and the barrier 2a is provided on the front surface of the nozzle tip 2. The air introduction part 4 which has is provided, or the channel | path connected between the opening 1a and the barrier | blocking 2a on the side wall of the nozzle main body 1 so that the side surface and AA cross section of an injection nozzle may be shown in FIG. Although it is necessary to provide the air introduction part 4 which has, it is changed suitably according to the size and shape of the nozzle main body 1 which type is selected.
[0019]
Moreover, the shape of the barrier 2a for generating bubbles can be applied to the shape shown in FIGS. 1 to 4 as well as the shape shown in FIG. 5 and other known shapes. What is necessary is just to select suitably according to the ejection pattern suitable for a viscosity, another characteristic, and a usage form.
[0020]
As the dispenser, a trigger type that checks the operation lever and injects the contents or a priming type that injects the contents by pushing the pressing head is applied.
[0021]
【The invention's effect】
According to the present invention, even if the contents remain in the injection nozzle, the ejection pattern can be switched and changed without touching the contents, and in particular, the contents are filled with a wiping agent or a bleaching agent. Usability is improved in containers that are in use.
