Abstract

<P>PROBLEM TO BE SOLVED: To prevent an inadvertent degassing mode setting operation of an aerosol product from being committed. <P>SOLUTION: A degassing mode is set by lowering and then turning a spray button 10. A cover body 20 is provided with notches 24a-24d and an annular hanging part 25. The button 10 is provided with a protrusion 12 for degassing mode setting and a removable standing piece 13 for preventing an operation error in a form matching the notches. When the piece 13 is not removed as shown in Figure, the button cannot be turned because the piece 13 remains in the notch 24c even in an operation mode where the protrusion 12 is positioned underneath the bottom face 25a of the annular hanging part. When the piece 13 is removed from the main body 11 of the button, the button can be pushed down for a turning operation. With this turning operation, the protrusion 12 is held on the bottom face 15a of the hanging part 25 by upward elasticity for stem energizing and a degassing mode is realized. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a degassing mechanism and a degassing mode setting member for an aerosol type product, and in particular, an opening of a cover body attached to an aerosol container between a stationary mode position and an operation mode position together with a stem. The present invention relates to a degassing mechanism that holds an operation button that moves up and down at a degassing position corresponding to an operation mode by a downward operation for setting the operation mode and a subsequent rotation operation.

  This degassing mechanism is required for the first time when the used aerosol is discarded, and is completely unnecessary at the use stage of the aerosol type product in which the contents still exist.

  For this reason, the shape and structure of the gas venting mechanism does not hinder the contents release operation during the normal use stage of aerosol type products, and so does not disturb the user. It is desirable that the mode can be easily set, and the present invention meets this need.

  Conventionally, as a degassing mechanism for holding an operation button at a degassing position corresponding to an operation mode by a downward movement operation and a subsequent rotation operation, for example, there is one disclosed in Patent Document 1 described later.

This degassing mechanism
-An engagement plate is formed at the lower end of the outer peripheral wall of the pressing head (operation button)
-A through hole that matches the engagement plate is formed in the inward flange of the surrounding cylinder (cover body) attached to the container body,
-When setting the gas venting mode, the push-down head is moved downward until the engagement plate passes through the through hole and then rotated relative to the surrounding cylinder to The plywood is set in a state where the upper surface portion of the plywood and the ceiling surface (lower surface) of the inward flange are in contact with each other (= gas venting mode position) and is held.
JP 2002-282746 A

  In the case of this conventional degassing mechanism, the rotation operation for setting the degassing mode after the push-down head is moved down to the operation mode position is free, and no blocking structure for the rotation operation is provided.

  Therefore, when the user unexpectedly rotates the pressing head set in the normal operation mode (downward movement position), the user enters the degassing mode while the head is held in the downward movement position. There is a problem in that it shifts in a manner that is contrary to the original intention of setting the operation mode, and is convenient in terms of usability.

  In addition, since the engagement plate for setting the degassing mode and the entire push-down head are formed as an integral molding (one piece), the degassing mechanism in the form of diverting the existing push-down head not provided with this engagement plate. There was a problem that could not be provided.

  Therefore, in the present invention, the operation button and the cover body (the operation button is attached to the aerosol container and the operation button moves up and down) and the operation button at the operation mode position are moved to the degassing mode and held. A mechanism to prevent accidental operation that prevents dynamic operation is provided, and by removing a part of this structure, the degassing mode can be set to prevent the operation button in the operation mode position from being unexpectedly rotated to the degassing mode position. The purpose is to ensure and stabilize the degassing mode setting operation which is not necessary in the normal use state in which the contents are contained in the container.

  Further, the component part for enabling the operation button to be rotated from its operation mode position to the degassing mode position and maintaining the state (degassing mode) is a member different from the button main body. The existing operation buttons that do not have the gas venting mode setting function can be set and held in the gas venting mode by attaching this separate member, so that the operation buttons of the aerosol type products can be effectively used as a whole. For the purpose.

The present invention solves the above problems as follows.
(1) Opening portions (for example, opening regions 26, 43 described later) of a cover body (for example, covering bodies 20, 40 described later) attached to an aerosol container (for example, a container body 70 described later) as a stem (for example, a stem 50 described later). In addition, an operation button that moves up and down between the stationary mode position and the operation mode position (for example, spray buttons 10 and 30 described later) is operated by a downward operation for setting the operation mode and a subsequent rotation operation. In the degassing mechanism that holds the degassing position corresponding to the mode,
The cover body includes a holding action portion (for example, a bottom surface 25a of the annular hanging portion 25 excluding a notch portion described later and a bottom surface 42e of the ceiling portion 42) for holding the operation button in the gas venting position,
The operation button is a holding action portion (for example, a protrusion to be described later) for preventing the return operation from the degassing position to the stationary mode position by an abutting action with the holding action portion based on the rotation operation. And 12),
Due to the action of the integrated part (for example, standing piece parts 13 and 33 described later) fixed to the cover body and the operation button so as to be separable to one of them and the integrated part before separation. A structure for preventing erroneous gas venting is provided, which includes an operation restricting portion (for example, notches 24b and 42b described later) that allows the operation button to move up and down and prevents at least rotation for setting the gas vent mode.
(2) Opening portions (for example, opening regions 26 and 43 described later) of a cover body (for example, covering bodies 20 and 40 described later) attached to an aerosol container (for example, a container body 70 described later) as a stem (for example, a stem 50 described later). In addition, an operation button (for example, a spraying button 30 described later) that moves up and down between the stationary mode position and the operation mode position is changed to the operation mode by a downward operation for setting the operation mode and a subsequent rotation operation. In the degassing mechanism that holds the corresponding degassing position,
The cover body includes a holding action portion (for example, a bottom surface 25a of the annular hanging portion 25 excluding a notch portion described later and a bottom surface 42e of the ceiling portion 42) for holding the operation button in the gas venting position,
The operation button is a holding action portion (for example, a protrusion to be described later) for preventing the return operation from the degassing position to the stationary mode position by an abutting action with the holding action portion based on the rotation operation. An existing button main body (for example, a press operation surface 11a, 31a described later) having a user operation surface (for example, a degassing mode setting main body portion 32 described later) made of a gas release mode setting member (for example, a gas discharge mode setting main body portion 32 described later). It is provided in the form of a separate member from the button body 31) described later.
(3) In the above (2), an integrated portion (for example, an upright piece portion 33 described later) fixed to one of the cover body and the degassing mode setting member in a separable form, and separation A gas vent comprising an operation restricting portion (for example, notches 24b and 42b described later) that allows the operation button to move up and down by the action of the previous integrated portion and prevents at least the rotation for setting the gas vent mode. A structure for preventing erroneous operation is provided.
(4) Opening portions (for example, opening regions 26, 43 described later) of a cover body (for example, covering bodies 20, 40 described later) attached to an aerosol container (for example, a container main body 70 described later) as a stem (for example, a stem 50 described later). In addition, it has a function of moving up and down between the stationary mode position and the operation mode position, and holding the stem at the degassing position corresponding to the operation mode by the downward operation for setting the operation mode and the subsequent rotation operation. Further, a degassing mode setting member that constitutes a part of an operation button (for example, a spray button 30 described later),
Engagement parts (for example, a stepped peripheral surface part 32a and a taper protruding part 32b described later) with an existing button main body part (for example, a button main body part 31 described later) having a user operation surface (for example, a pressing operation surface 31a described later), ,
Abutment with holding action portions (for example, a bottom surface 25a of an annular hanging portion 25 excluding a notch portion described later and a bottom surface 42e of a ceiling portion 42) formed in the cover body to hold the operation button in the gas venting position. A function part to be held to prevent the operation button from returning from the degassing position to the stationary mode position (for example, a protruding part of a degassing mode setting main body 32 described later);
The operation button is allowed to move up and down, and at least the rotation for degassing mode setting is prevented, and the blocking operation is performed by an action between the operation restricting portion (for example, a notch described later) and this. With an integrated part (for example, a standing piece part described later) in an aspect fixed in a separable form, provided with one (for example, a standing piece part 33 described later),
An aerosol type degassing mode setting member.

  An aerosol-type product having a gas venting mechanism having the above-described configuration and containing a gas for discharge and contents is also an object of the present invention.

  In this way, the present invention provides a structure for preventing the erroneous operation of the turning operation for shifting the operation button at the operation mode position of the aerosol type product to the degassing mode. For example, it is a degassing mechanism that requires the user to release, for example, an integrated part with the operation button, so that the operation button at the operation mode position is degassed by the user's careless or unconscious operation. The mode position can be prevented from being set, and the degassing mode setting operation which is not necessary in the normal use state in which the contents are contained in the container can be ensured and stabilized.

  In addition, since the operation button is composed of a button main body and a gas venting mode setting member which is a separate member, existing operation buttons that do not have a gas venting mode setting function are also used in this gas venting mode. If the setting member is attached, it is possible to set and maintain the gas venting mode, and the entire effective use of the operation buttons of the aerosol type product can be achieved.

The best mode for carrying out the present invention will be described with reference to FIGS.

  Moreover, the constituent element (for example, thin-walled portion 13a) of the reference number with alphabet is a part of the constituent element (for example, the standing piece 13) of the reference number without alphabet.

  The spray buttons 10 and 30 and the cover bodies 20 and 40 are made of plastic such as polypropylene, polyethylene, polyacetal, nylon, and polybutylene terephthalate.

The basic features of each degassing mechanism shown in FIGS.
(1) When the upright pieces 13 and 33 are connected to the button main body 11 and the degassing mode setting main body 32 as shown in the figure (= when not separated), the spray buttons 10 and 30 Can move only up and down, and its rotation is blocked by the concave portions 24b of the cover bodies 20 and 40. Therefore, this degassing mechanism is operated in the degassing mode (= the pair of projecting portions 12 of the spray buttons 10 and 30). Is not set or held in a state where the cover body 20 or 40 is moved to the lower side of the annular hanging portion 25 or the ceiling portion 42 and is in contact with the bottom surface 25a or 42e).
(2) When the standing piece portions 13 and 33 are detached from the button body portions 11 and 31 (gas venting mode setting body portion 32), the cover bodies 20 and 40 (notches 24b and 42b) for the standing piece portions. Therefore, when the user depresses the spray buttons 10 and 30 in the stationary mode to the operation mode position and rotates, the spray button is in the degassing mode (see FIG. 2). Set and retained,
This is what I did.

That is,
(3) At the stage where the contents still remain and are not to be discarded, the spray buttons 10 and 30 are used in a state in which only the up and down movement while being integrated with the standing pieces 13 and 33 is possible,
(4) At the stage where it is necessary to exhaust the contents and exhaust the residual gas in the container, the user is required to perform an extra operation such as separating the standing pieces 13 and 33 from the spray buttons 10 and 30; Thus, the spray button is prevented from shifting to the degassing mode from the normal operation mode due to a slight movement of the user's hand or the like.

  Note that the upright pieces 13 and 33 (the button main body 11 and the degassing mode setting main body 32) and the cover bodies 20 and 40 may be integrally formed in a state where they are connected by a temporary fixing portion.

  When the spray buttons 10 and 30 and the cover bodies 20 and 40 with the temporary fixing portion are attached to the stem 50 and the mounting cup 80 (container body 70), the temporary fixing portion functions as a so-called virgin seal. Will have.

  That is, since this temporary fixing part is torn off when the spray buttons 10, 30 are pressed, for example, if the temporary fixing part of the aerosol type product displayed at the store is still attached, , You can check if the product has been used even once.

  Moreover, in this attachment method with the temporary fixing portion, the management up to the attachment process of the spray buttons 10 and 30 (gas venting mode setting main body portion 32) and the cover bodies 20 and 40 is unified and efficient. .

  In the stationary mode of FIG. 1, the cover body 20 is fixed by being externally fitted to the upper outer portion of the mounting cup 80 with the convex portion 21 a and the annular step portion 23, and the spray button 10 is fitted with the stem 50. The opening area 26 is moved upward by a biasing force of a well-known spring (not shown).

  In this state, a well-known valve action part (not shown) of the stem 50 is closed, and the contents of the container body 70 are of course not injected into the external space.

  When the user depresses the pressing operation surface 11a of the spray button 10 in FIG. 1, the button and the stem 50 are moved down against the urging force of the spring, and the valve action part is opened. The contents are injected into the external space through “the valve action part—the stem 50—the passage part of the button main body part 11—the nozzle 14”.

The degassing mode in FIG. 2 is for the spray button 10 in FIG.
First, remove the standing piece 13 from the button body 11,
Next, the protrusion 12 is held in contact with the bottom surface 25a of the annular hanging portion 25 (the cover body 20) by pressing the button down to the operation mode position and then rotating in the clockwise direction shown in the figure. Set to state,
Is.

  Since the valve action portion of the stem 50 in the degassing mode is in the open state as in the operation mode, the residual gas in the container body 70 is discharged from the nozzle 14 to the external space through the same path as in the operation mode.

  The degassing mechanism of FIG. 3 is different in the structure of the spray button 30 from that of FIGS. 1 and 2.

In the case of the spray button 30 in FIG.
Use an existing operation button as the button body 31
The gas venting mode setting part (= gas venting mode setting main body part 32 + standing piece part 33) is a separate member from the button main body part 31,
The degassing mode setting main body portion 32 is fitted to the button main body portion 31 by the step peripheral surface portion 32a and the taper protruding portion 32b.

  The degassing mechanism of FIG. 4 is different in the structure of the cover body 40 from that of FIGS. 1 and 2.

In the case of the cover body 40 of FIG.
-The convex portion 41a and the flange portion 41b are internally fitted and fixed to the inner upper end portion of the mounting cup 80,
-Each of the four ceiling parts 42 has the same thickness,
In the degassing mode, the protruding portion 12 of the spray button 10 is held in contact with the bottom surface 42e of the ceiling portion.

The gas venting mechanism in FIG. 5 is a combination of the spray button 30 in FIG. 3 and the cover body 40 in FIG.
The spray button 30 is composed of an existing button main body 31 and a gas venting mode setting part (= gas venting mode setting main body 32 + upright piece part 33) which is a separate member.
The cover body 40 is fitted in the mounting cup 80.

(14) The protruding portion 12 for setting the degassing mode is formed on the cover bodies 20 and 40, and the concave portions (= notches 24a, 24c, 42a and 42c, the bottom surface 25a of the annular hanging portion, the bottom surface of the ceiling portion) 42e is formed in the button main body 11 and the degassing mode setting main body 32. The L-shaped concave portion consisting of a vertical portion and a horizontal portion following the vertical portion is provided.
(15) The standing pieces 13 and 33 are formed in the cover bodies 20 and 40, and the concave portions (= vertical concave portions having the same action as the notches 24b and 42b) are formed on the button main body 11 and the gas vents. Form in the mode setting main body 32.
