Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stopper mechanism that gives intermittent spraying capability to a spray container having a spray head, among other containers having various fluid discharge functions.
[0002]
[Prior art]
In the conventional spray container, what can be evaluated as practical for realizing the intermittent spray capability has not been provided. The intermittent capability imparting function that has been used in the past is, for example, an intermittent valve in which a heavy valve element closes a flow passage in response to a decrease in internal pressure in a fluid container, such as a gravity operated valve, or a fluid container, such as a spring operated valve. The flow passage opened by the internal pressure is opened when the valve body is pressed and deformed by the internal pressure in the fluid container, such as an intermittent valve or a differential pressure operating valve in which the spring presses and closes the flow passage as the internal pressure decreases. However, an intermittent valve or the like has been used in which the valve body returns to its original shape as the internal pressure decreases and the flow passage is closed.
[0003]
However, any of the above intermittent valves has a limitation that restricts the fluid supply amount (including the ejection amount, outflow amount, or discharge amount) based on the internal pressure of the container, that is, the supply amount is reproducible with a simple mechanism. The restriction that it was difficult to regulate well could not be avoided.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to improve the above-mentioned problems associated with conventional fluid containers, particularly spray containers. More specifically, an object of the present invention is to provide a stopper mechanism that can be easily operated simply by being mounted on a conventional spray container or the like without almost remodeling it, and can provide a reliable intermittent injection capability. More specifically, the object of the present invention is easy to attach and detach to and from the container neck, and is reliable in operation, and can be disposed of as a combustible material after detachment from the container (without requiring disassembly or separation). It is to provide a stopper mechanism that can be rotated.

DETAILED DESCRIPTION OF THE INVENTION
<Shape and material of annular or cylindrical stopper>
The case where the stopper mechanism of the present invention is ring-shaped or tube-shaped will be specifically described below with reference to the drawings. In the present invention, “up / down / left / right front back” and the like are expressions for convenience of explanation.
[0007]
The stopper of the present invention is formed of a material (elastic material) that is highly recoverable to its original shape even after a relatively large deformation due to an external force, whether it is a ring (ring) shape or a cylindrical shape (tube shape). At the same time, once the elastic material is shaped into a predetermined shape, it is expected that the shape can be maintained for a long period of time.
The annular stopper of the present invention is provided on a connecting cylinder member (including a first modified connecting cylinder member and a second deformed connecting cylinder member) located inside by a locking portion (locking means) formed on the inner wall surface thereof. As long as it can be engaged with the locking portion, the shape or type of the locking portion can be any.
[0008]
However, a practically preferable one of the locking portions in the present invention is a fitting and fixing method of a locking claw provided on one side and a locking through hole provided on the other side. However, the engagement method between the cylindrical stopper and the connecting cylindrical member may be different from these.
Further, in another preferred embodiment illustrated in FIG. 9 described later, a locking portion such as a locking through hole or a locking claw is provided on the upper half portion of the first deformable connecting tube portion of the integral SA member. It is not necessary to prepare. The reason is attributed to the completely different locking method used in this method.
[0009]
As a material resin (material resin) for molding the stopper of the present invention, from the viewpoint of practical use, on the premise of having the properties described above, moldability, retention, ease of molding, material price and productivity Considering other conditions, it is a thermoplastic resin, and examples thereof include a polyolefin resin, a polyester resin, a polyamide resin, and a hard polyurethane resin. Here, the “resin” is not necessarily limited to a crystalline polymer, but is a concept that includes what is recognized as a “resin” in the molding industry, is distributed, and is subjected to processing such as molding or shaping. .
[0010]
As a material for forming the stopper of the present invention, a crystalline polyolefin resin is one of the most suitable materials in average practicality among thermoplastic resins. Examples of the crystalline polyolefin resin include crystalline polyethylene, crystalline polypropylene, crystalline poly-1-butene, propylene-ethylene crystalline copolymer, and propylene-1-butene crystalline copolymer.
[0011]
The polyethylene resin and the polypropylene resin, which are the most practical among the crystalline polyolefin resins, will be further explained. In order to form a stopper, it is important that the crystalline resin is a crystalline resin. Among polypropylene resins, crystalline (stereoregular) polypropylene resin is dominant. Crystalline (stereoregular) polypropylene resin is advantageous in order to withstand the pressure steam sterilization treatment required for pharmaceutical applications, etc., but in addition to this, poly-4-methyl-1-pentene (Including copolymers with other 1-olefins) The resin is further advantageous in that it has high resistance to heat treatment (thermal deformation temperature and buckling strength).
[0012]
<Material of connecting cylinder member (generic name)>
In the present invention, what is crowned on the neck of the fluid container and realizes a locking relationship with various stoppers is a connecting cylinder member (generic name; including a first deformed connecting cylinder member and a second deformed connecting cylinder member). In addition to the realization of this locking relationship, the role of the connecting tube member is to fix the fluid discharge pump inserted into the neck of the fluid container to the neck upper end opening of the fluid container.
[0013]
In order to meet such a role, it is preferable that the material has chemical and mechanical properties required for the fluid container and the stopper. In addition, crystalline polyolefins that are suitably used for the creation of various stoppers for medical applications, foods, luxury goods, cosmetics and barbers, etc. that should naturally be expected to be ingested or at least contacted by the human body Resins are more suitable. Furthermore, this connecting tube member has properties that are not easily deformed even under constant load (creep deformation resistance), high temperature resistance (high thermal deformation temperature: HDT), moisture resistance, gas barrier properties (especially oxygen and carbon dioxide). 1) or more) is emphasized depending on the application. Non-crystalline cyclic polyolefins (homopolymers, co-polymers) are available as materials that satisfy high temperature resistance (high heat distortion temperature: HDT), moisture resistance, and gas barrier properties (especially oxygen and carbon dioxide). For example, a polycycloalkene resin is suitable. Examples of polymers already provided as amorphous polycycloalkene resins include homopolymerization or copolymerization of about 3 to 20 tricyclodecene polymerization units, tetracyclodecene polymerization units, pentacyclodecene polymerization units, etc. Can be obtained. The “resin” in the material resin used in the present invention is not limited to the “crystalline polymer” which is a narrowly defined resin, but has a low crystallinity as long as it is a hard polymer that is molded and traded as “resin”. Alternatively, even an amorphous polymer is included in the “resin” used in the present invention.
[0014]
<Material of fluid container>
The container used in the present invention, that is, the material forming the fluid container, can be used in most cases as long as it is the thermoplastic resin described above. Of these, crystalline polyolefin resin is suitable in many cases as a container forming material. However, since the crystalline polyolefin resin has a low melting point compared to other thermoplastic resins, even in the case of a polyethylene resin that is a low melting point resin, even if it is a high-density polyethylene located on the high melting point side, pressurized water Crystalline polypropylene (stereoregular polypropylene) resin is more suitable (durability) than polyethylene resin for applications such as steam sterilization that are used for a long time under a temperature condition close to the crystalline melting point. From another point of view, polyolefin resin is rich in acid resistance and alkali resistance, and has the advantage of being inert to the contained fluid, so that it can be used for medicines, cosmetics (cosmetics, dyes, etc.) In addition, it has established its position as a container for storing barbers (hairdressing, shaving, etc.), food, seasonings and luxury goods. In addition, when the required properties from the application place importance on one or more types such as high temperature resistance (high heat distortion temperature: HDT), moisture resistance, gas barrier properties (especially oxygen, carbon dioxide, etc.), they are exemplified in the previous section. In some cases, polycycloalkene resins may be suitable.
[0015]
In the present invention, the “fluid” includes any of gas, liquefied gas, and liquid. Among these, preferred are gas, liquefied gas and low boiling point liquid. The reason is attributed to the fact that the role expected of the fluid in the present invention is a propellant. Of course, for various applications, various main components are added to this fluid, and in some cases in the form of a solution, in other cases in the form of a suspension or emulsion (emulsion). Is housed in.
[0016]
<Explanation based on drawings>
<< annular stopper 4 >>
In the preferred embodiment of the present invention summarized in FIG. 1, FIG. 1 (A) shows that the annular (ring-shaped) stopper 4 of the present invention is substantially oval and is connected to the neck 1n of a fluid container (not shown) 1. The cross-sectional shape of the two engaging claws 41 fitted to the connecting cylinder member 2 and projecting from the inner peripheral surface thereof to the inside is connected to the neck 1n of the fluid container 1, respectively. A plane including the central axis (long axis) of the fluid container 1 in a state of being fitted and locked in a locking through hole (or locking recess) 2c located in the upper half 2u of the H-shaped connecting cylinder member 2 FIG. 5 is a schematic cross-sectional view of the annular stopper 4 having a substantially elliptical planar shape, as viewed from the long diameter line, in the schematic vertical cross-sectional view that appears after cutting at a point.
[0017]
In FIG. 1 (A), the fluid container 1 passes through a reduced diameter region provided in a middle stage region of a substantially bottomed cylindrical fluid storage portion (reservoir portion; not shown) 1h, and ends with a narrow neck portion 1n. A lower flange portion Pf of a discharge pump P, such as a spray pump, is mounted on the upper end opening 1m via an annular gasket G, and an annular ridge 2r protruding from the inner wall 2i of the connecting tube member 2 from above is disposed on the lower stage. By pressing and fixing the flange Pf, the leg pipe portion Pd of the pump P is inserted below the liquid level of the fluid containing portion 1h, and the contained fluid is sucked up by the spray pump P, and further from the pump P. The fluid is discharged (including spraying, jetting, and discharging) from the discharge port 3x opened at the upper end of the actuator 3 through the flow pipe portion 3c provided in the actuator 3.
[0018]
<< Connection cylinder member 2 >>
A female thread is usually engraved on the inner wall 2i of the lower half 2d of the connecting cylinder member 2, and this female thread is engaged with a male thread usually engraved on the outer wall of the fluid container neck 1n. . Here, the boundary separating the upper half 2u and the lower half 2d of the connecting tube member 2 is an annular ridge 2r projecting from the inner wall 2i. The annular ridge 2r serves to press and fix the discharge pump P for extruding the fluid contained in the fluid container 1 to the upper end opening 1m of the fluid container 1 through the annular gasket G from above. As the discharge pump P, a spray pump is usually used frequently.
[0019]
A male thread is engraved on the outer wall of the neck 1n of the fluid container 1, and this male thread is screwed into a female thread engraved on the inner wall of the lower half 2d of the separate connecting cylinder member 2 to be spray pumped. The lower flange Pf of P is clamped and fixed. On the side wall of the upper half 2u of the connecting cylinder member 2, a locking through hole (locking recess) 2c is formed. The locking through holes 2c are usually a combination of two vertically spaced apart, and two pairs are usually arranged symmetrically with respect to the center of the upper half 2u of the connecting tube member 2. . This locking through-hole 2c can be selected depending on the engagement method, whether it is a simple through-hole or a recess, but each mode in FIGS. In the structure in which the locking claw 41 projecting from the annular stopper 4 is supported by the portion penetrating to the inside of the connecting tube member 2 to prevent the descent, it needs to be a “through hole”.
[0020]
However, another method, for example, a malfunction prevention protrusion 4vu as illustrated in FIG. 11 prevents the actuator 3 from descending so that the bottom surface of the flange portion 3f of the actuator 3 starts from the vicinity of the top edge 4vt of the deformed annular stopper 4v. In the system protruding so as to abut, the locking means 43 can be a locking through hole or a locking recess (bottomed hole; engraved hole). However, the locking means may have a different form from the above. That is, one or more laterally running grooves are provided in the outer wall of the second deformable connecting cylinder member 2v2, and the inner wall surface of the deformed annular stopper 4v is provided with a lateral groove that can be fitted thereto, or the deformed annular stopper 4v itself. The aspect etc. in which is deformed to “a waveform running in the lateral direction” are also encompassed by the present invention.
[0021]
In each of the schematic longitudinal sectional views appearing after FIG. 1, the substance in which the lower half 2d outer wall of the connecting cylinder member 2 is indicated by a double line is a non-slip vertical groove knurl, and the connecting cylinder This is an allowance for facilitating rotation for screwing or detaching the member 2 on the outer wall of the neck 1n of the fluid container 1.
The base cylinder part 3b of the actuator 3 can slide up and down in the upper half part 2u of the connection cylinder member 2 connected (crown-mounted) to the neck part 1n of the fluid container 1 in FIG. It is fitted inside. Here, the boundary between the upper half 2u and the lower half 2d of the connecting tube member 2 is an annular ridge 2r projecting from the middle of the inner wall 2i of the member 2.
[0022]
The actuator 3 is formed of a composite body in which a substantially cylindrical base tube portion 3b, a substantially inverted trumpet type discharge outer tube portion 3z, and a flow pipe portion 3c attached to the inside thereof are joined. The upper end region of the part 3b is configured to be joined to the lower surface of the flange part 3f located at the lower end of the discharge outer cylinder part 3z. The lower end of the flow pipe portion 3c is substantially in contact with the top end of the valve operating rod Pr projecting from the top of the press operating valve, and when the actuator 3 is pushed down, the valve is operated by a distance sufficient to operate the press operating valve. Push down the rod Pr.
[0023]
FIG. 1B shows the same locking state, but is a schematic longitudinal sectional view of the substantially elliptical annular stopper 4 viewed from the minor axis direction of the elliptical shape. Therefore, according to FIG. 1 (B), it can be seen at a glance that the annular stopper 4 protrudes in the lateral direction. FIG. 1C is a schematic cross-sectional view that appears when the annular stopper 4 is fitted, cut along line AA (plane AA). The hollow arrows shown in FIGS. 1 (B) and 1 (C) indicate the direction of the external force applied to open the annular stopper 4.
[0024]
Returning to FIG. 1B and FIG. 1C, the annular stopper 4 is expanded outward in the direction of the minor axis substantially perpendicular to the pinching force indicated by the hollow arrow opposed on the major axis. As a result, the locking claw 41 is pulled out from the locking through hole 2c drilled (or recessed) in the upper half 2u of the connecting tube member 2 screwed to the outer wall of the neck 1n of the fluid container 1. Become. In order to temporarily fix the annular stopper 4 in the open (detached) state in this state, the annular stopper 4 is moved to the actuator 3 side.
[0025]
The movement limit of the annular stopper 4 at this time is that the top edge 4t of the actuator 3 (spray) is displayed on the lower surface of the flange portion 3f where the top edge 4t extends outward from the outer wall of the actuator 3 or in FIGS. 4 (I) and 4 (J) described later. Usually, it is sufficient to contact the lower surface of the flange portion 3f (including 31f and 32f) extending outward from the middle stage of the head) 3 (including 31 and 32). In other words, the upper edge 4t of the annular stopper 4 comes into contact with the lower surface of the flange portion 31f or 32f extending from the outer wall of the substantially middle region of the actuator 31 in FIG. 4 (I) and the actuator 32 in FIG. 4 (J) from below. The position is the upper limit of movement of the annular stopper 4. At this stage, the locking claw 4 1 is in contact with the outer wall of the connecting cylinder member 2 above the hook through the locking through hole 2c.
[0026]
Specifically, according to FIG. 1 (D), the locking claw 41 is carved on the outer wall of the upper half 2u of the connecting cylinder member 2 even after being pulled out (detached) from the locking through hole 2c. It is fitted in the guide vertical groove 2g, and can reciprocate on the same route while following the guide vertical groove 2g when the annular stopper 4 moves up and down.
FIG. 2 (E) shows a state in which the annular stopper 4 that is slidable upward is moving upward. This movement is also realized by pulling upward or pushing from below, and can be performed until the top edge of the annular stopper 4 abuts against the lower surface of the flange portion 3f of the actuator 3. Essentially, the movement of the annular stopper 4 changes the distance between the top edge 4t and the lower surface of the flange portion 3f of the actuator 3.
FIG. 2F shows a state in which the operation is performed so that the distance between the actuator 3 and the fluid container 1 approaches after the top edge of the annular stopper 4 abuts the lower surface of the flange portion 3f of the actuator 3. As a result, the fluid stored in the fluid reservoir (not shown) 1h is sprayed (injected) from the discharge port 3x opened at the upper end of the actuator 3. The composite of the annular stopper 4 and the actuator 3 is guided by the flange guide longitudinal groove 2g and moves downward, and finally the locking claw 41 is fitted into the locking through hole 2c to lock them.
[0027]
FIG. 2 (G) shows a state where the state has returned to FIG. 1 (A) again. Therefore, in this state, even if the actuator 3 is already pushed down (the connecting cylinder member 2 is pulled up), the locking action is hindered. However, in order to execute the above cycle again from this state, it is possible to perform the unlocking operation according to the above description.
FIG. 3H is a schematic partial enlarged longitudinal sectional view showing the state of FIG. In FIG. 3 (H), the left half is the locking claw 41 of the annular stopper 4 fitted into the locking through hole 2c formed in the outer wall of the upper half 2u of the connecting tube member 2, and immediately above it. The state which has prevented that the base cylinder part 3b lower end of the actuator 3 located is falling is shown. On the other hand, in the right half of FIG. 3 (H), the engaging claw 41 of the annular stopper 4 is detached from the engaging through hole 2c formed in the upper half 2u of the connecting cylinder member 2, and the connecting cylinder member 2 is It shows a state in which it can be slid upward while being guided in a guide vertical groove 2g formed on the outer wall of the upper half 2u.
[0028]
<< Deformation of actuator 3 >>
4 (I) and 4 (J) are modified embodiments in which different shapes 31 and 32 are mounted as the actuator 3, and the annular stopper 4 and the fluid container (not shown) 1 are locked. The embodiment is the same as in the embodiment shown in FIGS. 1 (A) to 3 (H). 4 (I) and 4 (J) show the fluid container 1, but the fluid container 1 is only shown as a schematic sketch. Accordingly, the illustration of the inside of the neck 1n is omitted.
[0029]
In the actuator 31 shown in FIG. 4 (I), the flow pipe portion 3c is turned at a substantially right angle from directly upward to laterally inside. Accordingly, when the actuator 31 is pushed down after the annular stopper 4 is opened, the inner solution is sprayed laterally from the discharge port (spray hole) 3x formed in the top side wall while the actuator 31 is lowered. become.
[0030]
The actuator 32 in FIG. 4 (J) includes a concentrated discharge member 3x1 directed in the horizontal direction at a position where the discharge port (spray hole) 3x of the actuator 31 in FIG. The role of the concentrated discharge member 3x1 is useful when the target sprayed by the fluid is small or when the fluid is efficiently sprayed to a target located in a narrow place surrounded by an obstacle.
[0031]
<< Annular stopper 4 and its variations >>
FIG. 5 (A) is a schematic cross-sectional view showing a cross section of the annular stopper 4 itself of the present invention cut horizontally along the same plane as the line AA shown in FIG. 1 (B). is there. This shape coincides with the figure showing the shape of the annular stopper 4 itself viewed from above.
[0032]
In FIG. 5 (A), the outer ring portion 4x of the annular stopper 4 forms a substantially elliptical outline, and two locking claws 41 from the opposed positions on the substantially short diameter are directed to the container 1 on the inner peripheral surface thereof. 4 grip pieces 4h from the inner periphery of the outer ring portion 4x are all mounted on the connection tube member 2 in order to securely hold the upper half 2u of the connection tube member 2 to be tightened. It protrudes in a substantially tangential direction with respect to the outer periphery of the half 2u. That is, the role of the four gripping pieces 4h is to grip the connecting cylinder member 2 fitted (externally fitted) to the neck 1n of the container 1 to be fitted from the periphery, and to connect the upper half of the connecting cylinder member 2 2u is positioned near the center of the annular stopper 4. However, the number of the gripping pieces 4h is not limited to four, and may be a larger number, for example, six may be used depending on the application.
[0033]
FIG. 5 (B) shows another embodiment (first modified embodiment) of the annular (ring-shaped) stopper 4 of the present invention. The annular stopper 4 of the present invention is clamped from both sides on the elliptical long diameter line. 5 (B) is different in that it is opened by being expanded outward on the short diameter line.
Therefore, in the embodiment of FIG. 5 (B), the protruding method of the locking claw 41 can be the same as that in the embodiment described up to FIG. 5 (A). In this embodiment, the outer ring portion 4x of the annular stopper 4 intersects with a substantially short diameter line (this position has two positions on the outer peripheral surface that are symmetrical with respect to the central axis). One detaching knob 42 is provided projecting outwardly from each other. The “pick surface” of the detaching knob 42 is substantially in the vertical plane in the embodiment of FIG.

To do. Here, the boundary that separates the upper half 2v1u and the lower half 2v1d of the first deformation connecting cylinder member 2v1 is an annular ridge 2v1r projecting from the inner wall 2v1i. The annular ridge 2v1r serves to press and fix the discharge pump P for extruding the fluid contained in the container 1 to the upper end opening 1m of the fluid container 1 through the gasket G from above. As the discharge pump P, a spray pump is usually used frequently.
[0039]
In FIG. 6 (A), the cylindrical stopper 5 is provided with a protrusion (including protrusions, protrusions, and undercuts) 5b protruding from the inner wall lower end region 5d toward the central axis, and the top edge 5u is first deformed. The lower end 2v1de of the connecting cylinder member 2v1 is engaged so as to be placed thereon, thereby preventing the self from being pulled out upward.

FIG. 6C is an overhead view of the state in which the cylindrical stopper 5 is mounted on the fluid container 1 in FIG. 6A, as viewed from above, with a wide ring occupying the outermost position (a part of the ring) In fact, this is the result of two ring notches being displayed close together. Out of the two ring notches, the outer ring notch is the outline of the fluid storage part (liquid storage part) 1h that occupies the lower half of the fluid container 1, and the inner ring notch is formed at the lower end 5d of the cylindrical stopper 5. A circle that is an outline and is located relatively close to the inner ring is an outline of the upper end 54 of the cylindrical stopper 5. Further, the substantially square portion projecting laterally from the vicinity of the upper end outline 54 is a detaching knob 51 extending outward from the outer wall of the lower end 5d of the cylindrical stopper 5, on both sides of the detaching knob 51. The elongated gap between the visible annular notch is a notch 52 and continues upward from the lower end edge 5d of the cylindrical stopper 5 with the release knob 51 interposed therebetween, and the release knob 51 is drawn outward ( This is a notch for easy pulling. Here, a narrow area between the two cuts 52 is referred to as a detaching tongue 53. The shape and positional relationship of each part are clearly shown in FIG.

FIG. 6D is an initial stage for detaching the cylindrical stopper 5, and the detaching tongue 53 starting from the detaching knob 51 is pulled out to the outer wall lower end 5d at the inner wall lower end 5d. The state which the engagement relationship of the part 5b and the lower end 2v1de of the 1st deformation | transformation connection cylinder member 2v1 removed is shown. In FIG. 6D, what is displayed in a circle defined at the right shoulder position is an enlarged display of the engagement relationship in the range surrounded by a circle at the right hem position in FIG. 6D. Although it is an enlarged longitudinal sectional view, no figure number is given. This is because it is determined that the engagement relationship can be read even in the display in the circle at the right foot position.

The state in which the content fluid is ejected upward from the discharge port 3x opened at the upper end of the actuator 3 as it is pushed down is shown.
FIG. 7 (G) is a schematic longitudinal sectional view. From the state of FIG. 7 (F), the cylindrical stopper 5 returns to the initial position together with the actuator 3, and the protrusion 5b at the lower end of the inner wall of the cylindrical stopper 5 is the first. 1 shows a state in which the lower end 2v1de of the deformed connecting cylinder member 2v1 is engaged so as to prevent an untimely operation of the actuator 3.
[0044]

It is a side sketch showing the state made. In FIG. 8, on the outer wall of the cylindrical stopper 5 of the present invention, two incisions 52 run upward from the lower edge 5d to a predetermined height, and an elongated area sandwiched between both incisions 52 is a tongue for detachment. 53. A relatively thin area is demarcated and displayed substantially horizontally at the lower end of the detachable tongue piece 53, and this area is a detachable knob 51.

<< Parts integrated type >>
9 is a third preferred embodiment of the present invention, and FIG. 9 (A) shows an embodiment in which the actuator portion 6a and the cylindrical stopper portion 6s are integrated, as shown in FIG. 9 (A). The aspect is substantially the same as the preceding aspects in that the first deformation connecting tube member 2v1 is screwed to the outer wall of the neck 1n of the fluid container 1.
[0046]
However, in the third preferred embodiment, as shown in the schematic longitudinal sectional view of FIG. 9A, the flange portion 6f (also called “flange portion 64”) of the actuator portion 6a is a cylindrical stopper portion. It also serves as the top plate portion 6s of 6s and extends downward to form a cylindrical shape. A part of the lower end 6d projects outward to form a release knob 61, which is an integrated actuator / stopper (abbreviated as “integrated SA member”). ) 6 is formed.
[0047]
However, both sides of the detaching knob 61 are cut upward from the lower end edge 2v1de of the first deformable connecting cylinder member 2v1 to form two cuts 62, while the narrow is sandwiched between the two cuts 62. The width area is the point where it becomes the detachable tongue 63 and the actuator part 6a of the integral SA member 6 is provided with an upward linear nozzle, through which the flow pipe part 6c penetrates and the discharge port 6x is opened at the upper end. There is no difference from the preceding embodiments in the points that are performed. Here, it should be noted that in the embodiment of FIG. 9, the flow pipe portion is “6c”, the discharge port at the tip thereof is “6x”, and the cylindrical stopper portion is “6s”.
[0048]
FIG. 9B is a schematic sketch of the state in which the integral SA member 6 of the present invention is mounted on the fluid container 1 as viewed from the side, and is removed from the lower end 6d of the cylindrical stopper portion 6s to the side. A release knob 61 extends and a notch 62 is formed upward from a position close to the starting point. On the other hand, the actuator portion 6a is turned to a lateral discharge type, and the fluid is discharged (sprayed; sprayed; discharged) from a discharge port (spray hole) 6x formed in the side wall 6t of the actuator portion 6a.
[0049]
9C is provided with a horizontal discharge member 6x1 that extends further in the horizontal direction from the side wall, instead of the discharge port 6x in FIG. 9B opening directly to the side wall 6t of the actuator portion 6a. A flow pipe 6c passes through the actuator 6a and supplies pressurized fluid sent from the pump P to the actuator 6a. The role of the horizontal discharge member 6x1 is useful when the target to be sprayed is small or when the fluid is efficiently sprayed to a target located in a narrow place where an obstacle surrounds the periphery.
[0050]
<Deformation mode>
10 is a fourth modified embodiment of the present invention, and FIG. 10A illustrates a modified annular stopper 7 of “paper clip type (gripper type)” as a modified embodiment of the annular stopper 4. To do. However, although it is a “paper clip type”, in this aspect, when the two parts bent into the saddle type are not opened in the state of the saddle, but are slightly opened to the sides to be separated into a pseudo heart shape, This is close to the fourth modification of the present invention.
[0051]
In the “paper clip type” deformed annular stopper 7 shown in FIG. 10 (A), the substantially elliptical (or oval) outer ring portion 7w is cut at positions 7w1 and 7w2 close to the major axis on the circumference. Thus, both ends 7w1 and 7w2 generated are bent to the longer diameter side. Both ends 7w1 and 7w2 of both intrusion areas 7b1 and 7b2 bent to the long diameter side are free ends, and both intrusions are caused by fingers entering between the intrusion areas 7b1 and 7b2. As a result of the area being expanded, the outer ring portion 7w is also expanded in the minor axis direction, and both locking claws 71 are locked in the connecting cylinder member 2 (including the second modified connecting cylinder member 2v2). Detach from the through hole 2c. The subsequent processes are the same as those in the annular stopper 4 described above.
[0052]
FIG. 10B is a schematic plan view of one mode for preventing the intrusion areas 7b1 and 7b2 of the “paper clip type” annular stopper 7 from separating during operation. That is, in the embodiment shown in FIG. 10B, either one of the intrusion areas 7b1 and 7b2 is formed in an interpenetrating state inserted through the guide cut 7i cut into the other, and is expanded according to the operation stage. Is then restored. As a result, there is no possibility that the inserted intrusion area 7b is separated from the other intrusion area 7b.
[0053]
FIG. 10C is a schematic sketch of the interpenetration state shown in FIG. 10B viewed from the major axis direction outside the ellipse.
The shape of the “grip” portion (outer ring portion) 7w of the deformed annular stopper 7 shown in FIGS. 10A to 10C is not limited to an ellipse or a parabola, but a rounded rectangle (including a square) and others Even if it is a polygon of this, what is necessary is just a shape excellent in the capability to restore the deformation | transformation by expansion to an original state. As a further different shape of the “grip” portion 7w, a so-called “pine needle type; V shape; Y shape” may be used.
[0054]
The mode integrated in FIG. 11 is a modified mode example in which the second deformed connecting cylinder member 2v2 fitted on the container neck 1n and the deformed annular stopper 4v fitted on the container neck 1n in the present invention are in a reverse engagement relationship. FIG. 11 (A) shows the engaging claw 21v2 projecting from the outer wall of the second deformable connecting cylinder member 2v2 that is formed at a position facing the substantially short diameter line in the outer ring portion 4vx of the deformed annular stopper 4v. FIG. 11B is a schematic longitudinal sectional view showing a state in which the deformed annular stopper 4v is fixed to the second deformed connecting cylinder member 2v2 by being inserted into the stop through hole 43, and FIG. A schematic front view (or a schematic side view) and FIG. 11C of the combination shown above show a cross-section that appears when the above-described deformation engagement mode is cut along a substantially horizontal plane (“line BB” in the drawing). It is the typical cross-sectional view looked down from.
[0055]
In the embodiment of FIG. 11, the base tube portion 3b of the inverted trumpet type actuator 3 similar to that in each of the preceding embodiments is shallowly fitted into the upper end opening of the second deformation connection tube member 2v2, and the second deformation connection tube member 2v2 described above. The pump P is housed in the same manner as in FIGS. 1 to 9 above, and the neck 1n of the container 1 is fitted and fixed in the space inside the lower half 2v2d of the second deformable connecting cylinder member 2v2. Has been. In other words, the pump flange Pf projecting from the outer wall of the discharge pump P is sandwiched between the lower edge of the annular protrusion 2v2r projecting annularly from the inner wall 2v2i of the second deformable connecting cylinder member 2v2 and the neck 1n upper end opening 1m of the fluid container 1 The discharge pump P is mounted in such a form. From this pump P, a leg Pd corresponding to the lower half thereof is inserted into the opening 1m of the fluid container 1, and a soft tube (not shown) extending further downward is immersed in the fluid to operate the pump P. Soak up fluid.
[0056]
Further, a fitting claw 21v2 for insertion is projected from the outer wall of the second deformable connecting cylinder member 2v2, and the deforming annular stopper 4v is fitted on the outside of the second deforming connecting cylinder member 2v2. Is inserted into a locking through-hole 43 drilled in, and both are detachably fixed.
The above-mentioned locking through-hole (locking insertion hole or locking recess) 43 is the most adopted form, and is formed in the form of a recess (engraved hole) instead of the locking through-hole 43. In such a case, unless the thickness (the radial length) of the deformed annular stopper 4v is considerably large, it is difficult to reliably lock the both.
[0057]
In each mode of FIG. 11, unlike the previous mode, the actuator 3 (including 31 and 32) is prevented from being accidentally lowered (pressed) or the second deformed connecting cylinder member 2v2 is raised (lifted). As a measure for this, a malfunction prevention protrusion 4vu is provided that protrudes upward from the top edge 4vt of the deformed annular stopper 4v. On the inner wall of the deformed annular stopper 4v, there is formed a guide vertical groove 4vg for guiding the locking claw 21v2 projecting from the outer wall of the second deformed connecting cylindrical member 2v2, and the deformed annular stopper 4v is at least in engagement. The same locking claw and locking through hole (locking recess) are also used when moving up and down (changing the distance between the malfunction prevention protrusion 4vu and the flange 3f of the actuator 3). The match is reproduced.
[0058]
However, the deformed annular stopper 4v does not contact the flange portion 3f with the entire length of the top edge 4vt, for example, and normally contacts at two or more points, preferably at least three points of center axis symmetry (point symmetry). In this case, the malfunction prevention function is fully expressed. Here, “two points” is not limited to strict point contact, but includes both length line contact and “narrow surface contact”. In the right half of FIG. 11 (A), a malfunction prevention protrusion 4vu projecting upward from the vicinity of the top edge 4vt of the deformed annular stopper 4v is slightly displayed in its longitudinal section. B) shows a mode in which the malfunction preventing portion 4vu is protruded upward in a substantially rectangular shape from the vicinity of the top edge 4vt of the deformed annular stopper 4v. The shape of the projection 4vu for preventing malfunction may be practically formed in a rectangular shape, a round-headed triangle shape, a trapezoidal shape, a mountain shape (waveform), or the like.
[0059]
【The invention's effect】
If the annular stopper or the cylindrical stopper of the present invention is used, the following various effects can be obtained:
(1) If it is in the fitted state, there is no worry of unscheduled operation during storage, and it can be easily shifted to the detached state with fingers when opened;
(2) After the stopper is opened by applying an external force from a specific direction or to a specific part, the stopper can be reliably returned to the initial state together with the actuator while discharging a predetermined amount of fluid. This sequence of operations can be performed repeatedly;
(3) Taking advantage of the fact that it can be operated with one hand, for example, a user who is incapable of using one hand can use the repeated discharge function;
(4) When two-handed operation can be assumed, the actuator can be operated with the other hand while the stopper is opened with one hand, and the stopper can be lifted and the process can proceed to the discharge stage. .
