Description

The present invention relates to an aerosol spray container capable of ejecting a spray gas from a nozzle by pressing a pressing head with a nozzle.

The aerosol-type spray container allows a spray gas to be ejected from the nozzle by fitting a push-down head with a nozzle to a stem that is erected upward from the upper surface of the aerosol can and pushing down the push-down head with the nozzle. However, if the aerosol can is discarded with the liquefied gas remaining in the aerosol can, there is a risk of explosion at the time of disposal, and thus degassing is performed at the time of disposal.
As a degassing means, for example, a thin gland is formed on the top plate of the cap so that a part of the top plate can be bent. At the time of disposal, the bent portion is bent and applied to the upper surface of the pressing head with nozzle. A device that automatically degass by holding a pressing head with a nozzle in a pressed state by making contact is known (Patent Document 1).
JP 2000-191062 A

  However, in the invention described in Patent Document 1, there is no need for a cap at the time of normal spraying, so the cap may be lost. For this reason, there is a risk of being discarded without being degassed at the time of disposal.

  An object of the present invention is to provide an aerosol spray container that can reduce the gas injection pressure when degassing at the time of disposal without the risk of losing the cover cap.

Therefore, there is no possibility of being discarded without being vented.

Further, according to the present invention, since the gas discharge window of the cover cap is in a position deviated from the front of the nozzle when degassing at the time of disposal, the gas ejected from the nozzle hits the inner surface of the cover cap and then from the gas discharge window. Since the gas is discharged outside the cover cap, the gas injection pressure when discharged outside can be reduced.

Furthermore, according to the present invention, since the positioning of the cover cap to the disposal position and the contact of the protrusion with the pressing head with the nozzle are performed at the same time, the gas injection pressure at the time of degassing is reduced. I will not forget my chemistry.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

The lower end of the cover cylinder part 11 is engaged with the lower end of the truncated cone part 3. A flange-like part 12 is formed at the upper end of the cover cylinder part 11, and a mounting cylinder part 13 whose upper surface is closed is provided through the inner periphery of the flange-like part 12. 4 is placed on the upper surface.

  A protrusion 14 is provided on the outer peripheral surface of the mounting tube portion 13 except for the rear portion, and a fitting protrusion 15 formed of a positioning protrusion is provided on the rear surface of the outer surface of the mounting tube portion.

  A fitting tube 16 is suspended from the lower surface of the inner peripheral portion of the flange-like portion 12 at the upper end of the cover tube portion 11, and the fitting tube 16 is fitted to the outer surface of the tightening portion 4.

  Reference numeral 20 denotes a push-down head with a nozzle. A push-down cylinder portion 22 whose upper surface is closed is erected from the upper end of the mounting cylinder portion 13 via an inward flange 21, and a connecting cylinder portion 24 is formed from the lower surface of the upper wall 23 of the push-down cylinder portion 22. And the lower part of the connecting cylinder part 24 is fitted to the upper end part of the stem 6. A nozzle 25 protrudes forward from the front portion of the connecting tube portion 24 through the push-down tube portion 22.

The upper wall 23 of the push-down cylinder portion 22 is formed with a recess 26 into which a projection 38 described later can be fitted. The concave portion 26 is preferably a groove having an arc shape that is long in the front-rear direction. The recess 26 constitutes a head pressing means 40 together with a protrusion 38 described later.

An arcuate split groove 29 is formed on the inward flange 21 provided at the upper end of the mounting cylinder 13 while leaving a part as an elastic plate 21a. When the push-down cylinder portion 22 is pushed down, the elastic plate 21a is elastically deformed downward and the portion surrounded by the split groove 29 is displaced downward.

  Reference numeral 30 denotes a cover cap. On the inner peripheral surface of the peripheral wall 31 whose lower portion is fitted to the outer surface of the mounting cylinder portion 13, a first groove portion 32 in the circumferential direction that can be engaged with the protrusion 14 and a protrusion (fitting) Fitting recesses 33 each formed of a second groove that can be engaged with the projections 15 are formed.

  The upper portion of the cover cap 30 is formed on an opening / closing lid 35 using a thin hinge 34. The opening / closing lid 35 is formed in a triangular shape when viewed from the side, and the thin hinge 34 is located at the upper end of the front portion of the peripheral wall 31. Since the opening / closing lid 35 is thus formed in a triangular shape when viewed from the side, the opening surface for opening / closing the opening / closing lid 35 is also formed in an inclined surface. Pushing operation is easy.

  A discharge window 36 through which spray gas is discharged is opened at the front portion of the peripheral wall 31 of the cover cap 30. The discharge window 36 is positioned in front of the nozzle 25 during normal use.

  A protrusion 38 hangs from the lower surface of the central portion of the top plate 37 of the cover cap 30. The protrusion 38 is formed in a side-view semicircular arc shape that is long in the front-rear direction, and is provided so as to be able to fit into the recess 26 described above.

Next, the operation will be described.
FIG. 1 shows a normal use state. The discharge window 36 of the cover cap 30 opens forward so as to be positioned in front of the nozzle 25, and the protrusion is in the closed state of the opening / closing lid 35. 38 is fitted into the recess 26.

  In order to eject gas from the nozzle 25, as shown in FIG. 4, the opening / closing lid 35 is rotated forward to open the lid, and then the pressing head 20 with the nozzle is pushed down by hand. A gas is ejected from the nozzle 25, goes straight toward the discharge window 36, and is ejected to the outside.

  In order to discard, after opening the opening / closing lid 35, it is only necessary to apply a turning force to the cover cap 30 in an arbitrary direction. Then, the protrusion 15 is detached from the second groove portion 33 in the circumferential direction and can be rotated. As shown in FIG. 5, the rotation angle is about 90 degrees. When the open / close lid 35 is closed in this state, since the protrusion 38 changes its direction in the direction perpendicular to the longitudinal direction of the recess 26, the protrusion 38 does not fit into the recess 26. It can come into contact with the upper surface of the pressing head 20 with the nozzle. On the other hand, the discharge window 36 is not positioned in front of the nozzle 25 and is turned in the left or right direction.

  Next, when the opening / closing lid 35 is closed, the protrusion 38 comes into contact with the upper surface of the pressing head with nozzle 20 and is held in the pressed state. The gas ejected from the nozzle 25 strikes the front inner surface of the cover cap 30 and is then ejected from the ejection window 36.

6 to 8 show a second embodiment.
The second embodiment and the first embodiment differ in the configuration of the head pressing means.
In the present embodiment, the head pressing means 50 is configured as follows. That is, the bent portions 51 and 51 are formed symmetrically with respect to the front portion and the rear portion of the top plate 37 of the cover cap 30, respectively.

Each of the bent portions 51, 51 is formed in a semicircular arc shape, and the arc-shaped portion is formed of a broken line 52 such as a thin portion or a perforation, and the linear portion 53 is formed to be bendable. Further, a fitting recess 54 made of a large fitting tube is suspended from one of the bent portions 51, 51, and a fitting projection 55 made of a small fitting tube is suspended from the other.

Therefore, the recess 26 and the protrusion 38 in the first embodiment are not provided in this embodiment. Since other configurations are the same as those of the first embodiment, the description thereof is omitted.

  In a normal use state, spray gas can be ejected from the nozzle 25 by opening the opening / closing lid 35 and pushing down the push-down head 20 with the nozzle, as in the first embodiment.

  At the time of disposal, the cover cap 30 is rotated about 90 degrees, the direction of the discharge window 36 is changed, and then the broken line 52 is broken while the opening / closing lid 35 is opened. The fitting projection 53 is fitted into the fitting recess 52 by bending 51 inward.

  Next, the open / close lid 35 is closed. Then, since the lower ends of the pair of bent portions 51 and 51 are in contact with the upper surface of the pressing head 20 with the nozzle and held in the pressed state, the degassing at the time of disposal becomes possible as in the first embodiment. The gas ejected from the nozzle hits the inner surface of the front portion of the cover cap 30 and then bends the bent portions 51 and 51 to be discharged to the outside from both the opening formed in the top plate 37 and the discharge window 36. Is done.
