13 FEB 2003 0 FB. RICE CO PATENT ATTORNEBtch No: m PCT/JPO2/05385 1/13 Specification An aerosol container with a cap Technical Fields The present invention celates to an aerosol container with a cap or cover, particularly a container for facilitating safe and easy release of a pressurized gas contained in such an aerosol container for discharging the same.
Background In a prior art, an aerosol container is widely used for discharging various kind of agent such as a paint, a cleaner, a hair-conditioner, an aromatic, and an insecticide. Such a container is used for not only an effective ingredient of the paint etc., but also a pressurized gas or an evaporable solvent for discharging the ingredient as a mist out of the container. These pressurized gas and the evaporated solvent may still remain in the container after the container is discarded as an out-of-use or unnecessary hrticle. The container with its content remaining therein should not be burned to discard, since it may be exploded. Moreover, the above-mentioned ingredient may be harmful to human body. Accordingly, it is desirable that the contents such as the gas are released before the container is discarded.
When the used out or unnecessary container is discarded, several methods are taken for releasing the gas or effective ingredient in the prior art. One of the method is to bore a hole on a body of the container by using a nail, drill, etc., by hand. The other one is to use a special boring device for making a perforation from which the gas or the ingredient is discharged. However, the former method may cause a problem in view of safety or sanitation, since the discharged content such as the gas may fall on a person who execute the boring operation. It may also causes an another problem that contents such paint may be discharged together with the gas and soil the person or the place therearound.
On the other hand, the latter method is not suitable for a personal or a home use, since it needs a place or cost for installing the device.
In view of the above problem, the following aerosol containers and cap assembly having gas release means are proposed.
PCT/JPO02/05385 2/1.3 Japanese Patent Application Laid Open 10 (1998)-53289 (which is referred to as document 1) discloses an aerosol container shown in Fig.
18(A) comprising a container body 103 with a mounting cup 104 from which a rod-shaped discharge head 1.02 is standing upwardly, and a cap 101 with a top wall having a fitting recess 105 which is contoured to be generally complementary to the container body's profile from the mounting cup to the rod-shaped discharge head, such that the cap is reversed to fit the periphery of the fitting recess 105 on the outer circumference of the mounting cup as shown in Fig. 18(B) such that the rod-shaped discharge head (102) is depressed by striking against the fitting recess so as to release gas outside through a gas release hole (106) formed at a portion of the fitting recess (105).
Japanese Utility Model Registration No. 3,056,237 (which is referred to as document 2) proposes an aerosol container shown in Fig. 19 comprising a cap with a slant top wall, a portion of the top wall is formed into a push button 110 by cutting its perimeter except for its lower side 1 10a such that the button is elastically bendable at the lower side so as to depress a discharge head 111 by its lower surface.
Japanese Patent Laid-Open No.11 (]999)-70986 (which is referred to as document 3) proposes a tilt-type aerosol container comprising a discharge head standing from the container body and being capable of tilting forward for discharging contents, and a cap for fitting on an upper portion of the container. Said cap has a rear wall, a portion of which is cut at its upper and lower margins to form an elastic band therebetween which is adapted to turnover inwardly against its elasticity so as to tilt the discharge head forwardly due to the turnover of the elastic band.
Japanese Patent Laid Open No. 2001-19067 (which is referred to as document 4) proposes an aerosol container comprising a cap with a top wall, a center portion of which is formed into a convex portion protruding upward, while a depression piece is protruding downwards from the convex portion, such that the discharge head is depressed by means of the depression piece by turning over the convex portion.
However, the container in document I is apt to be dirty since its fitting recess is easily soiled with dust. In the document 2, it is necessary to keep on depressing the push button for continuous discharge. And also the method according to the document 3 is only applied to the container with a tilt type discharge head. Furthermore, in the document 4, the gas release may start or stop unintentionally when the elastic band contacts with something else to elastically 22/07 '08 14:34 FAX 61386184199 FB RICE CO [o006 00

Mode of Carrying Out the Invention Figs. 1 to 4 shown a first embodiment of the p resent invention. The aerosol container 1 according to the present invention consists of a container body 2 and a cap 11. Hereinafter the words "front and rear" and "left and right" are used only for describing mutual relations of the components of the container.
The container body 2 comprises a discharge head 3 with a nozzle 4 opened forward, which is provided at the top of a stem (not shown) extending from an upper wall of the container body 2 in an upwardly biased manner. The discharge head 3 is adapted to discharge contents of the container by depressing it down against the upwardly biasing force. The top wall of the container body is connected to an outer circumferential wall at its perimeter formed as a winding end 7.
The cap 11 has a top wall 14 and a peripheral wall 12 depending from a perimeter of the top wall. Numeral 13 designates an engagement device such as an engagement rib provided at the lower edge of the peripheral wall 12, its engagement strength is sufficiently great to withstand against upwardly biasing force of the PCT/JP02/05385 6/13 discharge head upon the depression thereof as described later. The cap may preferably be made of flexible material, especially flexible synthetic resin.
A portion of the top wall 14 is formed into a folding plate (or lid) 17 which is enclosed by a bendable line 18 such as thin-hinge and a breaking line (or a fragile line). After breakage of the breaking line, the folding plate 17 is adapted to bend at the bendable line 18 inwardly, so as to open an aperture 15 within the breaking line 19 and the bendable line 18. The aperture is so sized to serve not only as gas releasing hole but also finger receiving hole into which a finger of a user may be inserted. The shape of the aperture may vary to any preferable shape. In a preferable shown embodiment, the bendable line 18 is formed into a straight line and the breaking line 19 is shaped into an arc spaced away from the perimeter of the top wall 14 with a constant interval. The breaking line may be a slit in which a plurality of severable pieces 19L are provided at intervals. The breaking line may also be a thin-walled portion shaping into a line.
In this embodiment, the aperture 15 is located eccentrically deviating from a longitudinal axis of the discharge head 3, rearward of the axis in the shown embodiment. as shown in Fig. 2. The bendable line 18 is formed between the front perimeter of the aperture closer to the longitudinal axis and the front margin of the folding plate defining its fixed end 17a adjacent to the front perimeter. The folding plate 17 has a depression plate 20 which is depending from its under surface and broad in its width in sideways (left-and-right direction).
Also, from an front half of the top wall 14 of the cap, there is depending a plate-like stopper (or an engagement plate) 21, which faces against the depression plate with the bendable line 18 and the longitudinal axis 20 of the discharge head interposing therebetween. As shown in the Fig. 3, an engagement projection 22 is provided at either one of the lower ends of the depression plate 20 and the stopper 21, while an engagement recess 23 is notched at the other, such that when the folding plate 17 is bent towards the interior of the cap, the engagement projection 22 is unremovably fixed at the engagement recess 23 fixing and thus locking the depression plate to the stopper 21.
In the above-mentioned structure, the outside of the folding plate 17 is generally flush with that of the top wall 14 in an initial state shown in Figs. 1 and 3, such that the folding plates serves like a part of the top wall to close the aperture Upon discarding the container, the user should remove the cap from the upper part of the container body 2, and depress the upper surface of the folding plate 17 from a state shown in Fig. 1. Then, the breaking line 19 is broken and the folding plate 17 PCT/JP02/05385 7/13 turns about the bendable lien 18 to a second position where it depends inward of the cap, such that the folding plate 17 is fixed to the stopper 21 by cooperation of the engagement projection 22 and engagement recess 23. Upon recapping the cap to the container body 2, the depression plate 20 depresses the upper side 5 of the discharge head 3 and maintains the depression state, allowing gas-release.
During gas-releasing, the folding plate 17 is located within the top wall 14 and peripheral wall 12 which retard an unfavorable contact of the folding plate with something else. Accordingly, unintentional interruption of the gas-release due to the contact is prevented, even though the user discards the aerosol container into the dust box in the middle of gas-releasing operation.
Hereinafter, other embodiments of the present invention are explained.
For ease of description, the explanation on the component of the structure which is generally equal to that of the previous embodiment is omitted, using the same numeral instead.
Figs 5 to 8 shows a second embodiment of the present invention. In this embodiment, the aperture 15 and folding plate 17 for closing it are provided in the peripheral wall 12 of the cap.
The aperture 15 has left and right margins either one of which is connected to adjacent end, i.e. fixed end 17a of the folding plate 17 via a bendable line 18, as shown in Fig. 6, such that the folding plate may turn about the bendable line 18 along a horizontal plane. In a preferred shown embodiment, the folding plate is configured to a band elongated in left-and-right sideways, and the breaking line is formed along the perimeter of the folding plate except for its right margin formed into vertical bendable line. The lower margin of the folding plate 17 is at a level generally corresponding to that of the top of the discharge head 3 in its lowermost position as depicted with an imaginary line in Fig. The plate-shaped stopper 21 is depending from the lower surface of the top wall 14 of the cap. The stopper is located anywhere on a diameter D of the cap's peripheral wall extending from the bendable line towards the center of the peripheral wall. In the shown embodiment, the stopper is provided between the bendable line 18 and the discharge head depicted in a broken line in Fig. 7.
The stopper may preferable be broad in its width in a direction perpendicular to the diameter D. A notch 24 is provided at a side edge of the stopper as shown in Fig. 8 at a level equal to that of the folding plate 17,such that a portion of the folding member 17 is fitted into the notch, while another portion of the folding PCT/JPO2/05385 8/13 plate contacts with the top of the discharge head to maintain the depressed state thereof. In the shown embodiment, lengthwise middle portion 25 of the folding plate 17 is adapted to be fitted into the notch, while the leading end portion of the same may contact with the upper end of the discharge head 3 in its lowermost position. The location and the length of the folding plate 17 may vary in the scope of the nature of the present invention.
In this embodiment, the outer surface of the folding plate 17 is generally flush with the outer surface of the peripheral wall of the cap in its initial state. Upon discarding the container, the user should remove the cap from the aerosol container, and push the folding plate 17 inwardly with a finger to break the breaking line 19.
By inserting the finger further into the aperture 15, the portion of the folding plate 17 is fitted into the notch 24. so as to engage the folding plate with the stopper to lock thereat. The depressed state of the discharge head is maintained by contacting the folding plate with the top of the discharge head 3.
Figs 9 to 11 shows the third embodiment of the present invention.
In this embodiment, the folding plate rotatable along a vertical plane is proposed in stead of the one rotatable along the horizontal plane in the second embodiment.
In this embodiment, the aperture 15 having a vertically elongated rectangular shape is provided in the peripheral wall 12 of the cap from its lower end to an upper portion of the same. The horizontal upper margin of the aperture 15 is connected to the adjacent end 17a of the folding plate 17 through the bendable line 18, while the breaking line 19 is defined between the folding plate and the vertical side margins of the aperture 15, such that the folding plate 17 may turn about the bendable line 18 after breakage of the breaking line from a first upstanding position to a second position protruding horizontally and inwardly.
Also the stopper 21 is depending from the top wall 14 of the cap and facing with the front wall portion of the cap's peripheral wall 12, such that the discharge head 3 is interposed between the bendable line 18 and the stopper 21. At the lower end of the stopper 21, there is provided engagement recess 23 for engaging with the free end 17b of the folding pate 17, such that the folding plate 17 contacts with the upper surface of the discharge head 3 in the engaged state to maintain the depressed state of the discharge head 3. It is more preferable that a pair of hooks 26,26 are provided at both sides of the lower end of the stopper 21 to form the fitting recess 23 therebetween, such that the pair of hooks catches the an engagement projection defined by the free end 17b of the folding plate.
Figs 12 to 17 show the fourth embodiment of the present invention. In this PCT/JPO2/05385 9113 embodiment, the pair of apertures with folding plates are provided in the top wall of the cap.
These apertures are front and rear symmetrical apertures of the same size and the same shape, and are separated by a rectangular partition plate 31. The both sides of the partition plate are connected to adjacent ends, i.e.
fixed ends 17a of the respective folding plates 17 via bendable line 18, while the remainder of aperture's perimeter having a U-shape is connected to corresponding edge of the folding plate 17 via the breaking line 19. Each said aperture serves as a gas release hole and a finger receiving hole of a size which is sufficiently great to receive the finger of the user. More over, it is preferable that the partition plate 31 is traversing right above the discharge head 3, and the width of the partition plate is smaller than the diameter of the discharge head 3.
Under the lower sides of the folding plates 17, 17, there are provided first and second fitting means 32,33 for providing mutual fitting. These folding plates are adapted to turn from a first position where the folding plate is flush with the peripheral wall of the cap to a second position where the folding plates are depending toward the inside of the cap to fit the first and second fitting means to fit each other, such that the folding plates are mutually integrated in a vertical posture by means of the fitting of the first and second fitting means.
Preferably, the first fitting means 32 may be a fitting cylinder, and the second fitting means 33 may be a protrusion which is able to press-fit into the fitting cylinder.
The folding plates 17,17 are formed by flexible plates. Moreover, it is necessary that the rotation radius of the folding plate, i.e. the length from the fixed end 17a to the free end 17b thereof is long enough that the free end of the folding plate contact to the corner 6 of the outer periphery of the discharge head 3 when the folding plates rotating from the first position to the second position as shown in Fig. 15. It is also necessary that the rotation radius is short enough that the free end 17b may forcibly ride over the corner 6 due to flexion of the folding plate when nipping the folding plates with fingers as shown in Fig. Furthermore, as shown in Fig. 12, 15, 16, the free end 17b of the folding plate 17 is provided with a chamfer portion 35 at a location where the free end contacts with the corner for facilitating the free end to ride over the corner. The chamfer portion may be provided at the corner PCT/JP02/05385 10/13 of the discharge head as shown in Fig. 17 which is a modified embodiment.
In the construction above, the folding plate 17is generally flush with the top wall 14 of the cap in its initial state shown in Fig. 12. Upon discarding the aerosol container, the user should push the upper side of the folding plates with fingers to break the breaking lines 19, such that the folding plates 17,17 are pressed into the cap, with each free ends coming to contact with the corner of the discharge head. The discharge head 3 is depressed when the free ends ride over the corner. And then the first and second fitting means 32,33 are fitted each other, and the folding plates 17, 17 achieve to the second position.
In this position, the first and second fitting means 32,33 connect the folding plates to be integrated each other, and each one of the folding plates acts as a stopper for fixing the other in a perpendicular posture.
