Abstract

PROBLEM TO BE SOLVED: To simplify and stabilize the attachment/detachment of a screw cap by preventing a variation in the fastening torque of the screw cap attached to the opening-side cylindrical portion of a refillable aerosol container and by preventing excessive close contact between the opening-side cylindrical portion and a sealing member.SOLUTION: The screw cap comprises: an internal screw cap 3 that has following pawls (3e and 3h) and screws at the opening-side cylindrical portion of a container body; and an external cylindrical cap 4 that has a drive pawl 4d and a rotation operating face 4a. The following pawls and drive pawl have orthogonal faces (3f and 3j, and 4e) and inclined faces (3g and 3k, and 4f) with respect to the direction of rotation. The inclined faces abut on each other when the screw cap is attached to the container body, and the orthogonal faces abut on each other when the screw cap is detached from the container body, thereby transmitting operation torque. When torque beyond a fixed amount is applied to attach the screw cap to the container body, the inclined faces slide over each other so that the external cylindrical cap 4 idly rotates to prevent the operation torque from being transmitted to the internal cylindrical cap 3.

Description

  The present invention relates to a screw coupling portion that is screwed with an opening-side cylindrical portion (hereinafter simply referred to as “opening-side cylindrical portion”) as required, and a container body that is attached to the opening-side cylindrical portion. The present invention relates to a screw cap or the like for a refillable aerosol container having a pressing action surface to a seal member.

  In particular, the entire screw cap is screwed into the opening-side cylindrical portion to exert a pressing action on the seal member, and the object to be directly rotated and tightened when attached to the opening-side cylindrical portion. The outer cylindrical cap (cover) is a separate member, and the caps are ratchet engaged with each other.

  By the ratchet engagement between the inner cylindrical cap and the outer cylindrical cap, the entire screw cap acts as a torque limiter.

  That is, the user once removes the screw cap from the opening-side cylindrical portion of the aerosol container body and replenishes the contents inside the container, and then again tightens the screw cap (outer cylindrical cap). When the rotation torque exceeds the predetermined value corresponding to the proper pressure contact state of the seal member when the operation is screwed to the container body, the outer cylindrical cap to be rotated is So to speak. After the transition to the idle state, the inner cylindrical cap does not rotate together with the outer cylindrical cap.

  As a result, the seal member that comes into contact with, for example, the upper annular portion of the opening-side cylindrical portion in accordance with the turning operation of the screw cap is excessively connected to the opening-side cylindrical portion by the user's too strong turning tightening operation. It is prevented from being set in a close state. In addition, variations in screw cap tightening torque associated with the rotation tightening operation are prevented from occurring.

  In this specification, the aerosol container body, screw cap, seal member, mounting cap, housing, operation buttons, etc. are completely assembled, and the contents (content liquid) and propellant (compressed air) are contained in the aerosol container body. The product in a state where is stored is described as “aerosol type product”. In addition, “compressed air” is described as an example of the propellant for discharging contents to the external space.

  Conventionally, instead of a mounting cap that is fixed to the aerosol container body by a method such as tightening and is not normally removed, it is screwed into the opening-side cylindrical portion by a user's turning operation. There has been proposed an aerosol injection mechanism that uses a screw cap (cover) that is provided and that is provided with an injection valve for refilling compressed air at the bottom of the aerosol container body (see Patent Documents 1, 2, and 3).

  Of course, in the aerosol type injection mechanism using such a detachable screw cap, the user rotates this in the removal direction to remove it from the substantially empty aerosol container body, and then newly adds the contents. It is possible to refill the container body.

  However, the screw cap is made of a single member, and the rotation operation force applied by the user to the screw cap is directly reflected in the pressure contact state between the opening-side cylindrical portion and the seal member.

  For this reason, when the rotational tightening operation force for attaching the screw cap of the user is too strong, the seal member pressed against the opening-side cylindrical portion of the aerosol container body along with the rotational operation is It will be attached to the cylindrical part in an excessively close state. In addition, the screw cap tightening torque tends to vary due to the rotation tightening operation.

JP 54-0778513 A Japanese Patent Application Laid-Open No. 08-156984 Japanese Utility Model Publication No. 62-130754

  In the aerosol-type injection mechanism using the conventional screw cap, when the seal member is set in an excessively close state as described above, the compressed air or the like leaks to the outside. However, if the aerosol type product is placed in a high temperature state, the internal pressure may rise abnormally and induce an explosion of the product itself. There was a problem.

  In addition, there is a problem that the screw cap tightening torque is likely to vary due to the rotation tightening operation.

  In addition, when the screw coupling force between the screw cap and the opening-side cylindrical portion is too strong, there is a problem that it is difficult for a user who wants to replenish the contents of the aerosol container body to remove the screw cap.

  Therefore, in the present invention, a screw cap that is screwed into the opening-side cylindrical portion of the aerosol-type container main body by a rotational tightening operation and press-contacts the seal member thereof, and an inner cylindrical cap that exhibits this screwing action and pressure-contacting action; In addition, this is a separate member and an outer cylindrical cap used for the rotation tightening operation, and these caps are engaged with each other by ratchet.

  That is, the screwing action of the inner cylindrical cap and the opening-side cylindrical portion based on the ratchet engagement at the time of the rotation operation ensures an appropriate predetermined sealing performance for the inner space region of the aerosol container body, When the pressure in the internal space region is excessively increased due to the high temperature of the use environment of the aerosol type product, a partial gap with the opening-side cylindrical part due to the deformation of the seal member is generated, The internal pressure of the aerosol container body is prevented from increasing by allowing compressed air or the like to leak from the gap.

  In addition, variations in screw cap tightening torque associated with the rotation tightening operation are prevented from occurring.

  Since a screw cap composed of such an inner cylindrical cap and an outer cylindrical cap engaged with such a ratchet is used, to what extent the user should rotate the outer cylindrical cap when the screw cap is rotated ( What is necessary is to operate the outer cylindrical cap until it is idle without worrying about how much the rotation tightening operation should be stopped), and the screwing state can be easily released.

  This facilitates and stabilizes each turning operation when attaching the screw cap to the opening-side cylindrical portion of the aerosol container body and when removing the screw cap from the opening-side cylindrical portion. The purpose is to improve the safety of product use.

  In addition, when the screw cap is removed from the cylindrical portion on the opening side of the aerosol container body, all the components except the container body can be handled in the form of a single unit with the screw cap, so that the liquid contents and compressed air can be recycled. The purpose is to improve the user's work when attaching a screw cap or the like to the aerosol container body after filling.

(3) The screw cap for a refillable aerosol container described in (1) or (2) above has a container body (for example, a container to be described later) having an injection part (for example, an injection valve 1d to be described later) for propellant filling. In the aerosol-type injection mechanism attached to the cylindrical portion (for example, the opening-side cylindrical portion 1a described later) of the main body 1) in the threaded state,
The cylindrical portion is
An outer peripheral surface screw portion (for example, a container main body side screw portion 1b described later) that is a threaded counterpart of the screw coupling portion (for example, cap side screw portions 3a, 13a described later);

(22) Even when the rotational operation torque from the user with respect to the outer cylindrical cap 4 is too strong, the annular seal member 6 is in the same state as when tightened with an appropriate rotational operation torque (= aerosol type product) The annular seal member 6 is deformed when the internal pressure is abnormally increased, and the compressed air inside the container body leaks to the outside) and is pressed against the opening-side cylindrical portion 1a.
(23) The screw cap tightening torque does not vary with the rotation tightening operation.
(24) Even after the screw cap 2 is removed from the opening-side cylindrical portion 1a, the engagement between the convex portion 3c and the annular concave portion 4h, the engagement between the inner cylindrical cap 3 and the mounting cap 5, etc. Thus, the other constituent members (screw cap 2, mounting cap 5, annular seal member 6, push button 7, stem 8, housing 9 and tube 10) excluding the container body 1 are united.
That is.

  As described in (22) above, when the internal pressure of the aerosol-type product containing the liquid contents and compressed air in the container body 1 tends to rise abnormally in a high temperature environment, the annular seal member 6 must be deformed. Occurs.

  For this reason, the sealing performance between the opening-side cylindrical portion 1a and the annular seal member 6 is somewhat lost, and compressed air or the like is removed from the container body 1 by “the gap between the opening-side cylindrical portion 1a and the annular seal member 6—the container body. Aerosol-type product due to leakage in the external space through the path of “the gap between the side screw portion 1b and the cap side screw portion 3a—the gap between the annular stepped portion 1c and the inner peripheral surface of the inner cylindrical cap 3” Will not explode.

20 is a stem joint for connecting the passage portion of the push button 7 and the upper end portion (downstream end portion) of the stem 8;

Respectively.

  The basic features of the aerosol injection mechanism of FIGS. 3 and 4 are the same as those of FIGS.

That is, as in the above (21) to (24),
(31) The screw cap 12 includes an inner cylindrical cap 13 that is screwed into the opening-side cylindrical portion 1a, and an outer cylindrical cap 14 that ratchets with the inner cap 13.
(32) Even when the rotational operation torque from the user with respect to the outer cylindrical cap 14 is too strong, the annular seal member 6 is in the same state as when it is tightened with an appropriate rotational operation torque. Pressed against la,
(33) The screw cap tightening torque does not vary due to the rotation tightening operation.
(34) After the screw cap 12 is removed from the opening-side cylindrical portion 1a, the other components (screw cap 12, mounting cap 5, annular seal member 6, push button 7, stem 8, The housing 9, the tube 10, and the stem joint 20) are a single unit.
That is.

  In addition, as in the aerosol injection mechanism of FIGS. 1 and 2, the aerosol-type product does not explode due to an abnormal increase in the internal pressure of the container (see [0030]).

  1-4, the container body 1, screw caps 2, 12, push button 7, stem 8, housing 9, tube 10 and stem joint 20 are made of polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate. These are made of plastic.

  The mounting cap 5 is made of metal, and the annular seal member 6 is made of plastic or rubber.

  In addition, you may fix the container main body 1 in the form which covers the plastic cylindrical part which formed the screw part 1b in the range of the opening side cylindrical part as a metal thing.

  1 to 4, the screw caps 2 and 12 of the unit are removed from the container body 1 when the content liquid is almost exhausted and replenished (refilled).

  The refilling of the compressed air from the injection valve 1d is performed in a state where the content liquid is replenished and the screw caps 2 and 12 of the unit are completely attached to the opening-side cylindrical portion 1a.

  Here, when the screw caps 2 and 12 (including the above unit) are removed from the opening-side cylindrical portion 1a of the container body 1, the outer cylindrical caps 4 and 14 may be rotated in the B direction.

  In accordance with the rotation operation in the B direction, the hanging surface 4e and the inwardly rising surface 14d of the outer cylindrical caps 4 and 14 are respectively extended to the long rising surface 3f and the short rising surface 3j of the inner cylindrical caps 3 and 13. The inner cylindrical cap is driven in the B direction in contact with the facing upright surface 1f.

  Since the contact surfaces of the outer cylindrical caps 4 and 14 and the inner cylindrical caps 3 and 13 at this time are directions substantially perpendicular to the rotation operation direction (B direction), the inner cylindrical cap and the opening-side cylindrical portion 1a. The screwed state is easily released.

  When the screw caps 2 and 12 of the unit are screwed onto the opening-side cylindrical portion 1a and attached, the user puts the unit on the opening-side cylindrical portion 1a from above, so that the outer cylindrical cap is placed. The outer peripheral surfaces 4a and 14a for rotating operation 4 and 14 may be rotated in the A direction.

With this turning operation in the A direction,
(41) First, the downward slope 4f and the inward slope 14e of the outer cylindrical caps 4 and 14 abut on the long upward slope 3g, the short upward slope 3k, and the outward slope 13g of the inner cylindrical caps 3 and 13, respectively. Drive the inner cylindrical cap in the A direction,
(42) By driving the inner cylindrical caps 3 and 13 in the A direction, the cap-side screw portions 3a and 13a are screwed into the container body-side screw portion 1b of the opening-side cylindrical portion 1a,
(43) When the screwing is advanced to the end and the rotational operation torque from the user exceeds a predetermined value, the inner cylindrical caps 3 and 13 are bent while the drive claws 4d and 14c of the outer cylindrical caps 4 and 14 are bent. Over the long upward slope 3g, the short upward slope 3k, and the outward slope 13g, the outer cylindrical caps 4, 14 shift to the idle state.

  Needless to say, in this idle state, the screwing operation between the cap-side screw portions 3a, 13 of the inner cylindrical caps 3, 13 and the container body-side screw portion 1b of the opening-side cylindrical portion 1a does not proceed.

  Therefore, even if the rotational tightening operation force of the screw caps 2 and 12 is increased, the annular seal member 6 is not excessively pressed against the opening-side cylindrical portion 1a. Further, there is no variation in the screw cap tightening torque.

  That is, when the internal pressure of the container main body becomes high due to an increase in ambient temperature or the like, the annular seal member 6 is deformed and compressed air or the like leaks from the container main body 1, so that the inside of the container main body is discharged.

  The rotational torque when the outer cylindrical caps 4 and 14 are shifted to the idle state is, for example, “60 to 100 N · cm”, and the internal pressure of the container body at the start of the exhaust pressure is, for example, “1 MPa”.

  When the push button 7 is pressed downward with the screw caps 2 and 12 attached to the container body 1, the stem 8 interlocks with the elastic force of the coil spring (not shown) in conjunction with a known valve mechanism (valve action). Part) shifts from the closed state to the open state.

  As the valve mechanism shifts to the open state, the liquid in the container main body 1 becomes “tube 10—inner space region of housing 9—valve action portion—inner space region of stem 8— (passage portion 20a of stem joint 20) — It is injected from the hole 7b into the external space via the passage portion 7a "of the push button 7.

  In addition, instead of the vertical movement type push button shown in the figure, a rotation type or tilt type operation button may be used.
