Dispenser 10 according to the present invention also comprises integrally formed installing mechanism, and it constitutes the parts of the one of housing 14.It is that 58 the mounting structure that is arranged on the complementation on the metope 12 removably is connected (Fig. 3) that this installing mechanism allows dispenser 10 and general label.In according to one embodiment of present invention, this installing mechanism is defined as the one molded features at the back side 18 of dispenser 10.This feature is not limited to the structure of arbitrary special shape, and comprises the connector or the connected structure of any suitable form, so that removably this housing is installed on the mounting structure that is arranged on the complementation on the metope 12.It is desirable to, as seeing among Fig. 3, the structure of this installing mechanism is centered on by " border " of back side of shell 18, so that by against metope 12 housing 14 being installed, the boundary member at the back side 18 just directly is resisted against on the metope 12.Use this structure,, and between housing 14 and metope 12, do not have the space basically, prize device and will lure a potential saboteur to fill in one by this space from arbitrarily angled this installing mechanism of all can't see.

In the illustrated embodiment, the installing mechanism feature of one comprises depression 50, and this depression mold pressing enters the back side 18.Limit this depression 50 by common vertical sidewall 52.Along sidewall 52 connected structure is set, so as be arranged on wall mounting structure 58 on complementary structure against engaging, as following describe in detail more.In the illustrated embodiment, limit this connected structure by the inclined-plane 56 that limits along vertical wall 52.Inclined-plane 56 is resisted against on the inclined-plane 62 that is limited to the complementation on the wall mounting structure 58 and engages, as seeing especially in Fig. 3 and 12.In the illustrated embodiment, at least two inclined-planes 56 are set, and separate by the part of vertical wall 52.These two inclined-planes 56 are resisted against on the inclined-plane 62 of wall mounting structure 58 and engage.For dispenser 10 is connected on the wall mounting structure 58, maintenance mans only need simply dispenser 10 to be located against wall installing mechanism 58, thereby just inclined-plane 56 vertically can be arranged between the inclined surface 62 of wall mounting structure.Then, maintenance mans only need simply just to make inclined-plane 56,62 joints, as illustrating especially among Figure 12 along vertical direction this dispenser 10 that slides.In this interlocking structure, can not from wall mounting structure 58, dispenser be dragged.Double inclined plane 56 structures that are arranged on each vertical wall 52 are particularly useful, because with respect to single inclined-plane 56 with same vertical table area, by less relatively the moving both vertically that needs between dispenser 10 and wall mounting structure 58, it provides the surface area of the increase interlocking on inclined-plane.

In a special embodiment of the present invention, can have " (play) moves about " of intrinsic degree or the back side 18 that flexible material forms housing like this by for example plastics.On the other hand, this wall mounting structure 58 can be by relatively material manufacturing harder, that rigidity is bigger (that is, metal or duroplasts support), and can have at least one size bigger than the correspondingly-sized of the depression 50 of housing (being the width or the degree of depth).For example, the width of the mounting structure 58 at 62 places can be less times greater than the corresponding cooperation width segments of the depression 50 that limits inclined-plane 56 on the inclined-plane.In this case, by housing is installed on the wall mounting structure, the parts of the large-size of this mounting structure will make appropriate section " bending " or the deflection in the housing depression, thereby hold the wall mounting structure of oversized dimensions.This structure provides several benefits.Unusual reliable and fastening joint between housing and wall mounting structure is provided, and it prevents that housing from rocking or with respect to the wall that supports moving of other is arranged.For the user, obviously housing can for good and all be screwed on the wall, perhaps otherwise is installed on the wall, and does not show that this housing can dismantle.As mentioned above, it is desirable to, can be fully enclosed in this depression in the boundary member of rear wall,, all can't see it from any angle so that support on the wall by this housing is installed to.Obviously, this housing rear wall can be directly fitted against supporting wall, has fully the separation of the unanimity of the minimum that limits around this rear wall.Also have, do not have king-sized power, can not drag or prize this housing down from wall mounting structure.

In case this dispenser 10 correctly has been positioned on the wall mounting structure 58, it is desirable to comprise positioner so, so that indicate this dispenser 10 correctly to locate and prevented the displacement of this dispenser 10 to the technical staff, and without concerted effort.In the illustrated embodiment, this positioner is made of the projection of protruding from the back side 18 of housing in depression 50 126.This projection 126 upwards slides into the inclined-plane 129 that is limited in the mounting structure 58, and snaps on the pit (divot) 128 of the correspondingly-sized that contiguous inclined-plane 129 is provided with.This wall mounting structure 58 can be made of the suitable syndeton of arbitrary form.In the illustrated embodiment, limit wall mounting structure 58 by flat-panel component 64, this flat-panel component for example appends on the metope 12 by bolt, bonding agent or analog.This wall mounting structure 58 is used to provide the engagement device of the interlocking that is used for this dispenser 10 simply.Obviously, can provide the joint construction of any type of interlocking, be arranged on the wall construction that supports the complementation on the wall thereby removably dispenser 10 is connected to.For example, at this back side, can provide similar devices such as simple relatively plug-in type fastener, spring-loaded latch.Desirable feature of the present invention is: whole dispenser 10 is disposable, and thus preferably relatively simply, engagement device more reliably.In this respect, have been found that the double inclined plane structure in this illustration and description is useful especially.

Provide the maintenance technician to be used for determining that the device of the level of viscous liquid in dispenser also needs.Thus, as mentioned above, can form the part of housing 14 by translucent or material transparent.Among the embodiment that illustrates especially in Fig. 1, whole back assembly 22 is formed by translucent or material transparent, observes remaining liquid level so that the maintenance technician can see from dispenser one side.In another embodiment shown in Figure 19, can be provided with one in any position of housing 14 by window transparent or that trnaslucent materials is made, the bottom of preferably close this housing, thus for providing, the maintenance technician sees that the holder the inside is to determine the performance of remaining amount of liquid.

As mentioned above, have interior magazine and integrally formed wall and the unique texture and the moulding of the housing of depression are installed allow dispenser according to the present invention to have the capacity that can significantly increase, and needn't increase " packing " (as top qualification) of this dispenser.For example, the dispenser according to of the present invention 2.5 liters of capacity is desired at present.The packing (pump machanism of housing and combination) of expecting this dispenser only weighs 250 grams.Like this, in order to keep and to safeguard 2.5 liters distribution " position ", only need the material of about 250 grams.On the other hand, if owing to destruction, the reasons such as pump that can not work again, traditional sleeve of same volume or the dispenser of directly filling must be changed, this housing and to recharge the weight that material adds together in fact bigger.For the dispenser of 2.5 liters of capacity of the present invention, weight (gram) capacity (liter) is than being about 100: 1.The applicant believes that this is significant an improvement that recharges on the dispenser (no matter be that sleeve is filled, still directly being filled in the housing from jumbo storage box) traditional.For the dispenser with bigger volume according to the present invention, 5 liters dispenser for example, the increase of believing packed weight is not a linear relationship, and along with the increase of capacity, weight-to-volume ratio will reduce.

Therefore, can design the dispenser of various volume capacities according to the present invention, wherein with the packed weight represented of gram with generally be not more than about 120: 1 and preferably about 100: 1 or littler with the ratio between liter volume capacity of representing.In a useful especially embodiment of the dispenser of 2.5 liters of capacity, this ratio is about 100: 1.

Obviously, dispenser according to the present invention is unrestricted on their size, as long as the weight of the housing after the installing mechanism between this housing and the wall mounting structure structurally is enough to support filling.

Figure 18 to 24 shows another embodiment of exhaust gear, and this exhaust gear can be used in according on the dispenser of the present invention.Steam vent 130 as shown in Figure 13 is the same, equates that by making the pressure between this holder and the surrounding environment these steam vents prevent to be pumped into vacuum in the holder 68.Referring to Figure 19 to 22, the openings 238 that a special exhaust gear 230 are configured to pass in the roof 232 of housing are provided with.This opening 238 also can be used as fills mouthful, is used for when initial filling to holder 68.This exhaust gear 230 comprises that general label is 250 body, its interlocking and engaging with wall portion 232 hermetically.In the illustrated embodiment, body 250 is inserted by opening 238, and the inner surface 236 that abuts against wall portion 232 automatically engages basically, thereby can not from housing, pull out this exhaust gear 230 later on.

Exhaust body 250 in an illustrated embodiment comprises body top 260 and body bottom 252.These parts can be separated molded or separately be formed, and link together subsequently, and the flange of for example seeing especially in Figure 18 links together.Can these parts be linked together by any traditional method, comprise bonding, ultrasonic bonding etc.These parts also can form the device of a single integral body, for example a single molded body part.

Body bottom 252 is parts of general cylindrical or truncated cone shape, the exhaust passage 258 below it limits.Constitute at least one preferably a plurality of flexible member on this body, for example elastic bumps 254, so that engage with housing wall portion 232 and fix.As seeing especially among Figure 20 A and the 20B, this elastic bumps 254 departs from vertical axis through body bottom 252, thereby they can curve inwardly when body 252 inserts by opening 238.In case should projection 254 cross the inner surface 236 of wall portion, their are just radially outward crooked so, as shown in Figure 20 B.Therefore, can not pull out exhaust gear 230 from housing later on.

Body bottom 252 comprises the projection 256 of rigidity basically, and they are located at interval between the elastic bumps 254, and is orientated through this body part and is in substantially parallel relationship to vertical axis.These projectioies 256 are defined as the structure of cage shape, so that accept body top 260.

Obviously, various Mechanical Builds may be used for limiting this flexible member and body bottom 252, and the embodiment that illustrates wants to limit the present invention.

Body top 260 is elements of general cylindrical, and it defines the exhaust passage, top 262 of finishing at exhaust apparatus 242.By the assembling of body top 260 and body bottom 252,262 aligned with lower exhaust passages 258, exhaust passage, top.

General label is that 244 venting plug is placed in the exhaust passage 262 movably, so that at the rest or the inactive state lower seal exhaust apparatus 242 of this exhaust gear.In the illustrated embodiment, venting plug is to lean against ball 246 on the inclined-plane 264 by spring 272 bias voltages.Like this, as can easily seeing in the accompanying drawings, in resting position, ball 246 be compressed against on the inclined-plane 264 and this exhaust apparatus 242 sealed.Holder 68 relative external environments are sealed basically.

This body top 260 comprises that also general label is 266 lid.The center of passing lid 266 limits exhaust apparatus 242.In the illustrated embodiment, lid 266 is tabular elements, and comprises flexible circumferential lip 268.This lip limit 268 defines first seal between exhaust gear and dispenser housing.Under the not compression or relaxation state that is shown in broken lines in Figure 21 and 22, this resilient lips has the radius of curvature greater than lid 266 remainder radius of curvature.By exhaust gear being passed and inserts shell nozzle 238, just lip limit 268 is pressed against on the surface of housing upper wall 232, and causes it to flatten and seal against surface of shell.In order to guarantee that constant compression force is applied on the lid 266, the vertical range " d " (seeing Figure 23) between the top of the edge on lip limit 268 and elastic bumps 254 is greater than the thickness of housing wall portion 232.Like this, fill in case this exhaust gear is passed housing wall, these elastic bumps 254 also produce a constant downward pulling force to lid 266 so, thereby make this resilient lips 268 press and be sealed on the surface of shell.

Body top 260 also comprises flexible skirt section 270, and it stretches out from following the facing down of lid 266.Bottom 271 is limited to the end in this skirt section 270.This skirt section and substructure define independently second sealing between exhaust gear and the dispenser housing.Referring to Figure 21 and 22, this bottom, skirt section 271 has the diameter that loosens or do not push, and this diameter is greater than opening 238 diameters that run through housing wall 232, as dotting in the accompanying drawings.Fill in by this exhaust gear is passed opening 238, can radially inwardly push this skirt section and this bottom 71 and lean against hermetically in the wall portion 239 of this opening and engage.
