Description

  The present invention includes a plastic body portion such as an operation button which is rotatable with respect to the container body side and communicates with the stem and through which the container body contents pass and an opening space area on the output side thereof. The present invention relates to a content discharge structure including a metal nozzle disposed in an open space area.

  In particular, the longitudinal and longitudinal directions of this open space area are inclined with respect to a reference plane (such as a horizontal plane) during assembly work, and are set in such a manner that they move in the direction of cancellation of the inclined state by rotation accompanying the contents discharge operation. The present invention relates to a content discharge structure for aerosol type products and pump type products.

  Thus, when a metal nozzle is incorporated in a plastic open space region held in an inclined state (see FIG. 1) from the work reference plane using a jig or the like, the metal nozzle is in the inclined state. Easy to set in different directions.

  When the above-mentioned deviation occurs in each inclined state between the metal nozzle that is the discharge portion to the external space area and the plastic opening space area that is the mounting partner that is immediately upstream, the seal between the metal nozzle and the contact partner It becomes inferior.

  In the content discharge structure in which a plurality of spiral grooves for generating a spiral flow are formed on the front end surface constituting the open space area, and the metal nozzle acts as a so-called ceiling portion of the spiral grooves, The degree of pressure bonding of the metal nozzle to the spiral groove-shaped portion of the metal tends to vary.

  The present invention eliminates the above-described problems such as poor sealing performance and variations in the degree of crimping in the contents discharge structure in which a metal nozzle is attached to the opening space area of the plastic main body (such as the button body). It is a thing.

  This content discharge structure can be mounted on each of an aerosol type product and a pump type product.

  In this specification, if necessary, the metal nozzle is set perpendicular to the longitudinal direction in the longitudinal direction of the mounting target portion, that is, the inclination of each inclined state between the metal nozzle and the open space in the above [0003]. Setting to approximately “0” is called “vertical set”.

  Further, the metal nozzle side (left side of FIG. 1, upper side of FIG. 2) in the longitudinal direction (left and right direction of FIG. 1) of the content discharge structure is referred to as “front”, and the opposite side (right side of FIG. 1, FIG. 2). The lower side is called “rear”. The horizontal direction in FIG. 1 is “horizontal”, and the vertical direction in FIG. 1 is “vertical”.

  2. Description of the Related Art Conventionally, a content discharge structure has been proposed in which a metal nozzle for content discharge is attached to an opening space area on the output side of a plastic button to stabilize a content pattern discharged to an external space area (Patent Document) 1).

JP 2012-70990 A

  In the case of the conventional content discharge structure in which the metal nozzle for discharging the content is attached to the output side opening space region of the plastic button, the button side is held in a horizontal state, not an inclined state, when the metal nozzle is attached. .

  Therefore, it is relatively easy to attach the metal nozzle in an upright state, that is, to set it vertically in the horizontal output side opening space region of the plastic button.

  However, it is not so easy to attach the metal nozzle to the output side opening space of the plastic button having the inclined state [0003] in the same inclined manner.

  In addition, the above-mentioned [0004] and [0005] seal defects and variations in the degree of pressure bonding are likely to occur in plastic buttons after the metal nozzle is attached.

Therefore, in the present invention,
(11) Instead of directly attaching the metal nozzle to the output side opening space area that is part of a plastic button (an example of a plastic body) and is in an inclined working environment,

Respectively.

  Here, the cover cap 1, the button body 2, and the nozzle holder 3 are made of plastic made of polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate, or the like.

  The metal nozzle 4 is made of various metals such as stainless steel and titanium.

The basic features of the illustrated content release structure are:
(31) When a plastic button main body 2 of a push-down rotation operation type in the C direction is used and the button main body is arranged in a horizontal state in the reference direction B in the so-called assembly operation of FIG. Assuming that the front-rear longitudinal direction A of the opening space 2f is a forward-declining inclination direction,
(32) The metal nozzle 4 is vertically set in a state of facing from the front in the annular gap 3e of the plastic nozzle holder 3,
(33) A plastic nozzle holder 3 that accommodates the metal nozzle 4 is incorporated in the front opening space 2f of the plastic button body 2 in an inclined state in the direction A.
And so on.

  In the above (31), the longitudinal direction A of the front opening space area 2f is set to the forward downward inclination direction in accordance with the push-down rotation operation in the C direction for discharging the contents to the button body 2. This is because the longitudinal direction is shifted in the horizontal direction.

  In other words, the content outflow direction from the nozzle hole 4b in the contents discharge state (the normal direction to the circular bottom 4a of the nozzle hole 4b) matches the reference direction B.

  The basic feature of the above is that the metal nozzle 4 exhibiting the pattern stabilization function of the released contents is not directly attached to the plastic front opening space 2f inclined in the direction A in FIG.

  That is, what is attached to the front opening space region 2f inclined in the A direction is a rear cylindrical portion 3a of the same plastic nozzle holder 3 as this. The non-plastic metal nozzle 4 is already incorporated in the front opening space 2 f of the plastic button body 2.

  The operation of incorporating the metal nozzle 4 into the plastic nozzle holder 3 can be performed in an environment in which the nozzle holder is held in a horizontal state in the B direction or in a vertical state orthogonal to the B direction (see FIG. 2).

  Therefore, the metal nozzle 4 can be incorporated into the nozzle holder in a vertical / horizontal manner facing the annular gap 3e (small-diameter inner peripheral surface 3f) of the nozzle holder 3 in the horizontal / vertical state. That is, the metal nozzle 4 is set in a vertical set with respect to the nozzle holder 3 in the horizontal / vertical state.

  By realizing this vertical set, it is possible to simplify and ensure the work of assembling the metal nozzle compared to the conventional case where the metal nozzle 4 is directly incorporated into the horizontal cylindrical portion 2c inclined downward in the direction A in FIG. Can be planned. In addition, it is possible to reduce the variation in the relative incorporation mode (position, orientation, deformation, etc.) of the nozzle holder 3 and the metal nozzle 4.

  The integrated nozzle holder 3 vertically set and the metal nozzle 4 accommodated in the nozzle holder 3 respectively have an inner peripheral surface of the horizontal cylindrical portion 2c inclined downward in the A direction and an outer peripheral surface of the front opening sheath-shaped portion 2d. Is mounted in the rear opening manner in the front opening space 2f between the two.

  In the assembling work in the rear-up mode of the integrated body (nozzle holder 3 and metal nozzle 4), only the plastic nozzle holder 3 hits the plastic button body 2. The metal nozzle 4 does not hit the plastic button body 2.

  Due to the so-called separation action of the metal nozzle 4 from the button body 2, even if the nozzle holder 3 incorporated in the button body in a rearwardly inclined manner slightly deviates from the original assembling position, the metal nozzle 4 and the nozzle holder are formed. There is no substantial effect on the content discharge channel.

  Similarly, contact portions of the plastic button body 2 and the nozzle holder 3 (the outer peripheral surface of the horizontal cylindrical portion 2c, the rear inner peripheral surface of the front opening sheath-shaped portion 2d, and the inner outer peripheral surface of the rear cylindrical portion 3a). Even if deformation or biting occurs, there is no substantial influence on the nozzle 4b of the metal nozzle 4.

  Further, when an integrated object composed of the nozzle holder 3 and the metal nozzle 4 accommodated in the nozzle holder 3 is incorporated into the front opening space 2f of the button body 2, the operator does not press the metal nozzle portion inside the front end surface of the integrated object. Alternatively, only the nozzle holder portion outside the front end face may be pushed.

  Thus, if only the nozzle holder part is pushed backward and the above-mentioned integrated body is incorporated into the button body 2, the front end face of the rear opening sheath 3c of the nozzle holder 3 and the circular bottom 4a of the metal nozzle 4 are pressure-bonded. The state is hard to change.

  Due to the fact that this crimping state is difficult to change, deformation of the straight groove portion 3g, the central recess portion 3h, the spiral groove portion 3j and the outer peripheral annular space 3k of the nozzle holder 3 can be suppressed, and in the operation mode after product assembly. The content discharge pattern from the nozzle hole 4b is stabilized.

  In the aerosol type product with the contents release structure (cover cap 1, button body 2, nozzle holder 3 and metal nozzle 4) shown in FIG. 1, the contents are released by pushing down the upper rear part of the button body 2 in the C direction. The operating mode of the state is set.

  At this time, the well-known valve action part on the stem side is opened, and the contents to be released that are already accommodated in the container body integrated with the cover cap 1 are released from the nozzle 4b of the metal nozzle 4 into the external space area by the action of the propellant. Is done.

  The contents discharge path to the external space area is roughly “valve action part—stem internal passage area—L-shaped passage part of the vertical cylindrical part 2b / horizontal cylindrical part 2c—straight forward passage part 3m of the nozzle holder 3; The groove-shaped portion 3g, the outer peripheral annular space region 3k, and the spiral groove-shaped portion 3j—the nozzle hole 4b of the metal nozzle 4 ”.

  Here, the rectilinear groove portion 3g and the spiral groove portion 3j are formed at equal intervals of 90 degrees in the circumferential direction of the rear opening sheath portion 3c. In addition, the inflow port of the spiral groove-shaped portion 3j is disposed at a substantially middle portion in the circumferential direction of the outflow port of the adjacent straight groove-shaped portion 3g.

  As described above, the outlet of the straight groove portion 3g is disposed at the circumferential intermediate portion of the inlets adjacent to the spiral groove portion 3j, so that the flow from the straight groove portion to the outer edge annular space 3k flows. The contents uniformly flow into the four spiral groove portions 3j.

  Then, the contents flowing into the central concave portion 3h at the tip of the spiral groove portion 3j become a stable swirling flow and are discharged from the nozzle 4b of the metal nozzle 4 to the external space area.

  Due to the uniform inflow of the contents into the spiral groove-like portion 3j, it is possible to expect the momentum of releasing the contents into the external space and stabilization of the emitted particle diameter.

  When the user stops the push-down rotation operation in the C direction, the button body 2 moves upward (opposite to the C direction) by the elastic force of a well-known coil spring (not shown) and corresponds to FIG. Return to the still mode position. At this time, it goes without saying that the known valve action part returns to the initial closed state and finishes the content discharge operation.

Of course, the present invention is not limited to the above embodiments, for example,
(41) Use a content discharge structure in which the front opening space area 2f of the button body 2 is set to have a front upper inclination opposite to that shown in the figure with respect to the reference plane during assembly work.
(42) Instead of the rear opening sheath 3c of the nozzle holder 3, a solid cylindrical portion is formed.
(43) Using a trigger lever type content discharge operation part,
(44) Attach cover cap 1 and button body 2 to various container bodies such as plastic and glass in addition to metal.
