-1 vinyl acetate units Chemical group 0 description 1
This invention relates to a self-closing valve-and-lid assembly adapted for closing the open top end of a container fillable with pressurized product.
For instance, German Offenlegungsschrift 27 22 265 of George Bernard Diamond describes a pressurized can which is closed off at the top by a lid, preferably of metal such as aluminium, and which is equipped with a discharge valve mounted in the center of the lid, on a common central axis of the valve-and-lid assembly.
It is another drawback of known valve-and-lid assemblies that insertion of a sleeve or stem part
of an atomizer head or of a filling head used for introducing product and/or propellant into the interior of a container leads frequently to damage of parts of the valve, especially the small elastically resilient valve disc or gasket that these valves usually require.
A valve-and-lid assembly having the features of the precharacterizing part of claim 1 is known from US-A-3144179.
It is, therefore, an object of the present invention to provide a valve-and-lid assembly, the manufacture of which is simpler than that of the known assemblies and which requires a minimum number of parts, each of which is in itself easy to manufacture.
a lid with a central opening and which lid is rigid under conditions of filling product into and discharging product from a container, and a valve body of elastically resilient material, the valve body comprising
a) a valve head having an annular face forming a sealing surface for sealing contact with an annular shoulder surrounding the central opening of the lid,
b) a flange supported at least around its periphery by a portion of the container lid separated axially from the annular shoulder,
c) a valve stem interconnecting said valve head and said flange and having a radial diameter the same as or smaller than that of the valve head, the valve stem being hollow and defining an upwardly open cavity extending from the flange and closed at the bottom end thereof, the valve stem including a deformable portion which is stretched in axial downward direction toward the interior of the container when the valve is opened,
d) duct means extending through the wall of the valve stem to connect the interior of the container to the cavity for product flow when the valve is opened (as known from US-A-3144179), characterized in that
the bottom end of the cavity in the valve stem is near the radial plane in which the sealing surface of the valve head extends,
the portion of the lid adjacent the annular shoulder extends transversely to the axis of the container and
the valve stem is provided with additional annular sealing means spaced from the valve head and adapted to make sealing contact at all times with a portion of the lid located between the annular shoulder and the flange support portion, the duct means being arranged between the sealing surface of the valve head and the additional annular sealing means.
Elvax 3120 is an ethylene-vinyl acetate copolymer resin made by E. I. DuPont de Nemours, Wilmington, Delaware, it contains 7.5 weight-% of vinyl acetate units and has a density of 0.93 g/ cm3 and a melt index of 1.2 g/10 min (ASTM D-1238), while the even more preferred polyester elastomer Hytrel 4055, which is also made by
DuPont, has a melting point of 168°C, a softening point of 112°C, a density of 1.17 and a tensile strength of 415 kg/cm2. Further details about these substances can be found in pamphlets of the above-mentioned American company.
In a further embodiment, the valve disc comprises a sleeve part depending from the contact zone and extending downward into the interior of the collar portion between an inner wall of the latter and the riser tube, and the riser tube has an open top end at a level in the collar portion spaced from the contact zone of the valve disc above the collar portion; the sleeve part has at least one window therein opening into the space between the open top end of said riser tube and the contact zone of the disc thereabove.
In a further, preferred embodiment of the valve-and-lid assembly according to the invention, the dome part protrudes from the flat lid part on the side of the latter adapted for facing away from the interior of a container, when the assembly is mounted on the container.
In this case, the actuating means are advantageously connected with the inner valve disc face inside the central opening of the dome part and protrude upwardly out of the opening. More particularly, the actuating means can be of tubular shape and can have an axial passage, which registers with the central opening of the dome part, and an inner end wall resting in positive contact with the contact zone of the valve disc inside the central dome part opening; this end wall of the actuating means has at least one port therein, adapted for registering with a gap formed between the annular rim of the collar portion and the contact zone of the valve disc, when finger pressure is exerted on the actuating means. The tubular actuating means can advantageously be integral with the valve disc.
The actuating means can also comprise a valve actuating rod which is mounted centrally on the outside surface of the valve disc, and an enveloping, preferably conical mantle having a discharge opening at its top end or apex and a circumferential foot rim which is connected with the same outside surface of the valve disc but outside the outlets of the ducts of the valve disc.
The opening at the apex is closed, in rest position, by the preferably conically tapered tip of the rod, thus providing a second sealing in addition to the primary sealing effect between the valve disc and lid. This double seal does not require any special precision manufacturing and will nevertheless be satisfactory when pressures prevailing in the container on the product are 3 to 5 bars in excess of ambient pressure.
Advantageously, the valve disc face opposite the inner disc face, which opposite face is turned toward the interior of the container, comprises a peripheral skin portion covering the underside of the entire lid which underside faces toward the interior of the container. This skin portion covering the underside of the flat lid part and the periphery of the lid, protects this lid underside against corrosion. In this case, the lid can be made of a material such as tin plate, which is less resistant to corrosion than the preferred aluminium.
Further objects, interesting features and other details of the invention will become apparent from the following description of preferred embodiments of the invention in connection with the accompanying drawings in which
The sidewall 15 of the dome part 12 comprises an annular region 15a which is crimped to firmly clamp in a peripheral zone 21 of a valve disc 20. The latter has a disc part 22 proper which extends across the base of dome part 12 and bears on its underside face 20a, turned toward the interior 5 of can 1, a valve head 23 which depends from underside face 20a to extend axially through the central' dome opening 16 and to end beneath the rim 18: of collar portion 17.
The actuating means of this embodiment is indicated by phantom lines in Fig. 1. It can be a tubular sleeve 40, for instance, of an atomizer head of the type used conventionally with spray cans. The lower end 41 of sleeve 40 can be tapered and fit in the correspondingly bevelled rim 34a about cavity opening 34 in top face 20b of valve disc 20.
At the same time, sealing rib 28 remains constantly in sealing contact with the inner wall surface 17a of collar portion 17, thus preventing penetration of product into the space 27, in which product could age and dry up and thus impede proper actuation of the valve disc 20. It is therefore particularly important that the entry orifice 35a of duct 35 is located between shoulder 26 and sealing rib 28'of the valve head 23.
Fig. 5 shows an improved way of mounting the riser tube 45 on the collar portion 47. The latter has its lower free end crimped outwardly to provide an outer collar flange 49. The curved crimping bend of the collar portion 47 provides an advantageous configuration for the rim 48 against which shoulder 26 of valve head button 25 abuts with improved sealing effect. At the same time, the outer edge 49a of collar flange 49 cuts into the material of the heat-widened top portion of riser tube 45 when the latter is cooled, providing a particular safe hold of the tube on collarflange 49. Also, the riser tube is spaced further away from the shoulder 26 of valve head button 25 than in the embodiment of Fig. 3.
Outflow of product through duct 35 is particularly facilitated by having the duct inclined inwardly and upwardly in the direction of product flow therethrough (Fig. 8), by having the entry orifice 35a located at a lower level, nearer shoulder 26 of valve head button 25 than the exit orifice 35b which is located in the inner wall surface 33 of cavity 30 preferably at the same level above the cavity bottom 32 as sealing-member 28.
Especially in an embodiment having no free space intermediate the flat region of valve disc 60 and the dome part top wall 53 underneath the same, a preferred manner of mounting the valve disc in the lid dome part affording a particular firm seat and improved sealing action between the shoulder 66 of valve head button 65 and the rim 58 of collar portion 57 is achieved by providing, at manufacture of the valve disc 60, a distance D1 between the underside face 60a of valve disc 60 and shoulder 66 thereof which is smaller prior to mounting the valve disc in the dome part 52, than is the distance D2 between the upper surface 53a of flat dome part top wall 53 and the rim 58 of collar portion 57 of the dome part 52 (Fig. 9). By the stretching of the distance D1 to become equal to D2 when mounting the valve disc 60 in the dome part 52, there is obtained an additional bias of shoulder 66 against collar portion rim 58. Also, the outer wall zone in which the underside face 60a of the valve disc 60 merges with the stem part 64 can be devised as a conically bevelled annular zone 67 which is urged against the bended junction zone of flat top wall 53 with collar portion 57, thus adding an additional contact zone and enhanced biasing and sealing effect to the annular zone 67 which helps to keep valve disc 60 and the upper portion of stem part 64 rigid while only the lower stem part is stretched when opening a gap between elements 58 and 66 by pressure on bottom 32 of cavity 30.
In this case the valve disc 60 is held so fast in position in dome part 52 that a crimping of the dome sidewall to clamp in the periphery of valve disc 60 can be dispensed with. In the embodiments of Figs. 1 to 5 a similar manner of mounting the valve disc in the dome part will not offer quite the same advantages, as the disc will be bent inwardly in closed position, and its path of travel during opening may become too short. In Fig. 6 however, the same advantages can be obtained when mounting the valve disc in the dome part in the same manner as in the case of Fig. 9, because the disc periphery 21 is clamped in.
Sleeve 91 is provided with a cutout or port 91 a at the bottom end thereof to permit product flow from duct 85a into the hollow interior of sleeve 91.
In an attempt to provide for a valve-and-lid assembly according to the invention in which the dome part of the lid does not penetrate so far into the upper space of the can interior 2 as in the preceding embodiments, the embodiment shown in Fig. 12 has a dome part 112 of lid 110 that protrudes upwardly, i.e. away from the can interior 2, and is crimped to clamp in the periphery of a valve disc 120 which bears a valve head 123 with stem part 124 and valve head button 125 similar to these elements shown in Figs. 1 and 2. The collar portion in this embodiment is constituted by a circular indentation 128a in flat lid part 113 about the foot end 112a of dome part 112, whereby an annular sealing bead 128 is formed which protrudes downwardly toward the can interior 2 from the underside 113a of lid 110. The shoulder 126 of valve head button 125 is urged firmly and sealingly with bias against this sealing bead 128, obturating the duct 135 which extends through stem part 124. The same mounting mode for generating this bias is used as in the case of the embodiment of Fig. 9.
In Figs. 13 and 14 there is illustrated a preferred way of mounting a sleeve 191 of spray head 190 in the cavity 30 of valve disc 20. In order to avoid the need for radial adjustment of a port 91 a (Fig. 10) to register with the exit orifice 35b of duct 35, there are provided in the bottom 32 of cavity 30 short radial ribs 32a on which the straight bottom rim 192 of sleeve 191 comes to rest.
In the embodiment of Fig. 15 the valve head button 125 is covered on its downwardly facing surface 125a by a protection cap 29 of corrosion- resistant material.
The provision of a space 27 (Figs. 1 and 2) underneath the valve disc 20 inside the dome part 12 has the further advantage that the thickness of the valve disc 20 can be considerably greater than in the conventional gaskets used in the known aerosol spray can valves (see description of gasket 202 in Fig. 18, infra). The wide cavity 30 permits introduction of a filling head or of the stem of an atomizer head without the danger of damaging a functional portion of the valve disc or of having a lacking seal along the cavity sidewall 33, thus avoiding the fountain effect during filling that is feared when filling a conventional aerosol can through its valve.
In the embodiment shown in Fig. 20, the valve disc 60 is of the same stopper-like configuration as in the embodiment of Fig. 9, while the lid 152, which bears the same collar portion 57 as in Fig. 9 is integral with the sidewall of a container depending from the lid itself. The container sidewall can then be sealingly connected to a container bottom part, e.g. by crimping in a manner known per se.
In the embodiment of Fig. 21, the metallic lid is replaced by a stopper-like lid 101 which replaces the central portion of lid 110 in Fig. 12 or the entire lid, and, in the former case, is mounted firmly and sealingly in the upper opening 102 of the annular metallic lid part or in the corresponding top opening of a container sidewall 103. The lid 111 is made of a synthetic plastics material which is substantially harder than the synthetic material of which valve disc 101 consists. The upper portion 107 of lid 101 has an inner peripheral groove 111a a of rectangular cross section in which the periphery 111 a of valve disc 111 is clamped in sealingly and firmly. From the underside of upper lid portion 107, there depends a lower sleeve portion 108 constituting the dome part of the lid 101. On its outer peripheral side, lid sleeve portion 108 projects with an annular bulge 109 beneath the neck part 103a of container sidewall 103, while on its upper annular face 108a, it supports the underside of valve disc 111. The latter is clamped into the central opening 108b of lid sleeve portion 108 by having the shoulder 166 of valve head button 165 rest against the underside 108c of sleeve portion 108 with bias in the same manner as described relative to Fig. 9.
Fig. 22 shows an embodiment in which the valve disc 180 is of somewhat similar construction as in the embodiment shown in Fig. 10. The dome part 172 of the lid, however is vaulted downwardly from the outer surface 170a of the very short flat lid part 170, and is provided in its top part 173 with an annular indented bead 171 which reinforces the dome part 172 against being distorted when the periphery at 170b of the lid is crimped on to a container sidewall (not shown). The collar portion 177 extends in this embodiment, axially outwardly from the top wall 173 of the dome part sidewall 177, at the upper free end 177a of which there is firmly mounted the upper end 180a of valve disc 180. The valve head 185 has its contact face 186 at its periphery and engages sealingly the inner wall 178 of collar portion 177. Several annular ribs 179 about the valve disc stem part 184, above and below duct 185a through the valve disc, engage the same inner wall 178 and effect a type of labyrinth seal therewith. Actuation of the valve in this assembly has been described in connection with Fig. 10.
A very similar embodiment is shown in Fig. 23, and like numerals therein indicate identical parts in Figs. 22 and 23. However, in this embodiment, the valve disc 280 has a sealing element which is a flexible annular flange 279 surrounding and integral with valve head stem 284, which flange comes to lie with its upper side 279a against the inner zone 178 of the lid underside about the bottom opening of collar portion 177, while the contact face 286 of valve head button 285 sealingly presses with bias against the underside 279b of annular flange 279. The actuating means for this embodiment are preferably identical with those shown in Fig. 10 and operate in the same manner when the valve is to be opened.
Finally, Fig. 18 shows a conventional valve-and-lid assembly comprising an atomizer head and dependent sleeve as actuating member. Such known valve comprises a lid 200, a valve housing 201 which is held at the lid 200 by means of an indented portion 200a of the latter, an elastically resilient valve disc or gasket 202 the peripheral region 202a of which is wedged in between a dome top wall 212 and the top rim 203 of valve housing 201. A steel spring 204 one end of which rests on the housing bottom 205, urges a valve body 206 with its upper obturating rim 207 into sealing engagement with the underside of valve disc 202. A sleeve of the atomizer head 210 is inserted into the top opening 213 of dome top wall 212 and rests upon the top face 206a of valve body 206. Depression of the atomizer head 210 compresses the spring 204 and opens a gap between the obturating rim 207 and the valve disc 202, whereupon product can flow from a riser tube 215 through valve housing 201 and through the aforesaid gap into a port 214 in sleeve 211 and through the interior of the latter to the spray nozzle 216 in atomizer head 210.
