2. Description of the Related Art One of the known stoppers for use exclusively in wine-type bottles is French Patent F.
It is disclosed in R-A-2232489.

This stopper is one on the stopper axially oriented between the lower end flange and the upper platform.
And two rubber seals mounted on the upper end of the stopper for compressing the seals between the lower flange and the upper platform so as to deform the rubber seals radially and outwardly against the rigid bottleneck wall. And a cam lever device, thereby forming a sealing plug for the bottle. However, this configuration is only applicable to bottles where the bottle neck has extra strength and rigidity.

Another known type of device which can use a similar principle for the wine bottle stoppers described above is disclosed, for example, in WO 90/09342. In this case, there is a spout for insertion into the planar wall of the container, and the device has a piercing into the container to provide fluid communication between the interior of the container and the external spout portion of the device. It has a part for insertion. The device also has a cam lever, which operates a sealing device that clamps the spout against the container in a leak-free manner.

[0005]

It is an object of the present invention to provide an attachment for a container with a mouthpiece, the attachment being a rigid material which acts as a closure member for the container or as a dispensing means or preferably both. It's not just necessary.

[0006]

SUMMARY OF THE INVENTION Accordingly, in one aspect of the present invention, an outer element for placement outside a container mouth, a deformable member for placement inside a container mouth, and an outside Means for cooperating with the element to deform the deformable member in a sealing and / or gripping relationship, such that the mouth of the container is sealable and / or grippable between the deformable member and the outer element. An attachment for a container with a mouth is provided.

The deformable member for sealing and / or gripping the wall of the container mouth is preferably an elastomeric material, for example rubber. The member may take any suitable shape, for example it may be cylindrical or frustoconical, or in some embodiments multiple cross-sectional shapes, each having a different one of these shapes. In a generally preferred embodiment, the deformable member is in the form of an annulus (phenol).

The shape, resilience and / or material of the deformable member depends on the sealing and / or material for which the attachment is desired.
Or it may be selected according to the degree of gripping. The above will also depend, for example, on the contour and material of the container mouth with which the attachment is used. Furthermore, it will also depend on the force exerted on the deformable member via the deforming means. For example, if a large deforming force of the deformable member is applied, a strong gripping effect will be produced on the container mouth, while a smaller deforming force will result in a less effective seal. However, depending on the magnitude of the deformation force, and by any of the other parameters above,
It may still provide sufficient gripping capability for the attachment to perform its desired function.

In the preferred attachment embodiment according to the invention, an outer element in the form of a shroud having several different configurations is used. Preferably it has a generally cylindrical portion which, when the attachment and the container are combined, abuts the mouth of the container and thereby provides a carrying element, whereby the element is deformed relative to it. The deformable member is pressed so that it is sandwiched between the element and the container mouth outer element wall to grip and / or seal.

The shroud forming the outer element of the attachment is, if desired, designed to fit and conform to the outer contour of the area of the container at or near the container mouth. This characteristic shape not only provides certain aesthetic opportunities, but is also important in connection with the construction as well as the operation of the attachment of the present invention. In that case, means for deforming the deformable member will be provided at least in part and will involve the configuration and form of the outer element in combination with the structure or shape of the container mouth.

Thus, according to the invention, the deformation means can be provided as mechanical parts of the device, separately from the outer element. The deformation means therewith is also a mutually internally engageable member provided by the outer element and the container mouth, which acts to provide the container mouth with an attachment in a manner compatible with the construction of the device. The required deforming force is applied to the deformable member below.

The mutual and internally engageable members of the outer element and the container mouth have one or more shoulders or protrusions on one of the outer elements, with corresponding recesses or the like on the other outer side. Own on top of the element. The action of bringing each of these members into mutual engagement provides the force necessary to deform the deformable member between them. In another embodiment, the interengageable members are interlocking helical threads, the action of screwing the outer element onto the container mouth imparts the required deforming force to the deformable member between the two elements. To do. The above-described interengageable member embodiments as specific examples of suitable deforming means will be described in detail below as preferred embodiments of the present invention.

In another preferred embodiment of the attachment of the invention, the means for deforming the deformable member in cooperation with the outer element into a sealing and / or gripping relationship is a separate mechanical member of the device, which member is It can be manipulated when it is necessary to have the effect of the safety of the attachment to the container mouth.

In one practical form of this embodiment, the means for deforming the deformable member comprises a fixed element, a core axially movable within the container mouth, and axially spaced from the fixed element. A core portion, a deformable member maintained between said portion of the core and the fixing element, and means for axially moving the core within the container mouth, the movement of which is A first position in which the possible member is virtually undeformed,
Between a second position in which the deforming member is deformed into a sealing and / or gripping or sealing and / or gripping relationship under the cooperation of an outer element.

The radial and outward deformation of the deformable member associated with the axial movement of the core is preferably accomplished through the use of lifting gores. The core has a lifting portion, for example a projection or a shoulder or a flange, which is located below and away from the fixing element. Therefore, when the core is lifted, the deformable member located in the space between the lifting portion and the fixing element is deformed by being compressed outward in the radial direction,
As a result, sealing and / or gripping is achieved in cooperation with the outer element.

Lifting of the lifting core is preferably accomplished by the use of a cam lever device, which itself is conventional as mentioned in the wine bottle stopper example above.

In the embodiment of the attachment according to the invention, the deformation means enabling the device to be clamped onto the container mouth can be acted in the opposite direction, whereby the deformation means is released and already fixed in place in the container. Attachments may be removed from the container. This configuration allows the attachment tint of the present invention to be used repeatedly on different containers.

In a preferred embodiment of the invention, the attachment has a delivery means such as a spout which communicates with the interior of the container when the attachment and container are in the assembled condition. As a result, the contents can be dispensed, for example, from a container via a spout or spout.

Thus, in an embodiment of the invention, the attachment has one or more passageways, and in the case of a fixed combination of container and attachment, the passageway (eg one main opening or a plurality of openings). The product in the container can pass through the container via the outside. In practice, the spout can be closed, for example by means of a screwdriver or a snap-on cap. Such a cap preferably forms the dispensing means and is used, for example, for the purpose of measuring the required amount of product dispensed from the container.

The container to which the attachment according to the invention can be combined is such that the container has a mouth which can be sealed or / and grasped between the deformed inner member and the outer element of the device. It can have any shape.

As used herein, the term mouth, when the attachment of the present invention is used in a container, refers to any type of portion generally cylindrical or frustoconical, and having an oryth. The form is such that the material in the container can be dispensed through the orifice. The term container thus means not only containers such as pre-homed or preformed bottles but also bags, for example plastic bags or bags made of composite material. The bag has an opening formed in the bag through which the contents of the container can be distributed. The openings may be formed, for example, as indentations or separations in the back corners shortly before the attachment of the device, or alternatively formed or incorporated as patches or similar protective elements that can be removed directly immediately before use.

Preferably, the application container of the attachment according to the present invention is a bottle-shaped or box-type container with a mouth, which is a semi-rigid or substantially rigid material by molding, including those of plastics or fiber systems such as cellulose. Is formed by. Cellulosic fiber materials are particularly preferred as they are environmentally friendly and biodegradable, and examples of such organic fiber materials are well documented in the patent literature. Preferably such a container comprises a shell of molded cellulosic material, the interior (and preferably also the exterior) of which is a substance impermeable to the in-container product, for example a polymeric material. Is lined with.

[0023]

The preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Various embodiments described in detail below are:
It is provided as an example only and is not intended to limit the spirit of the invention to any particular configuration or design. A given attachment, including various individual features from one or more exemplary embodiments, may fall within the scope of the invention.

Referring to FIG. 1 a, the main components of the attachment of this first embodiment are: shroud 4, rubber sealing element 6, lifting core 10, cam lift ring 1.
2 and the cam lever 30. Threaded cap 5
0 is provided as an attachment on the top of the lifting core 10, and the spout 20 is preferably formed in the core integrally therewith. The interior of the cap 50 is preferably provided with a content return feature, eg a cylindrical flange 52 (see FIG. 1b)), so that the cap is a metering / dispensing unit for the product to be dispensed from the container. It can be used as a good effect on the battery.

The shroud 4 has a generally cylindrical portion 5 and, integral therewith, a substantially annular portion 9 forming the previously defined fastening element.

The lifting core 10 includes a central passageway through which the product can pass, and also includes a peripheral projection 15 as a lifting portion. The peripheral projection forms a space between the projection and the annular portion 9 of the shroud 4 in which the cylindrical rubber sealing element 6 is housed.

The cam lift ring 12 is held rigidly to the lifting core 10 by, for example, a threaded joint 16, which facilitates easy assembly of the device. Extending outwardly and diametrically opposite the cam lift ring 12 is a ridge 14 adapted to be inserted into an opening or recess 32 in an arm 34 of the cam lever 30. There is. Each arm 34 is formed as a cam, so that the cam lever 30 has a handle portion 3
As it is pivoted by manual operation of 6, the cam surface of the arm 34 abuts the upper surface of the annular portion 9 of the shroud 4, thereby causing the cam lift ring 12 to move axially in relation to the shroud 4. The cam configuration of the arm 34 keeps the device in either its non-sealing / non-gripping action or its sealing / gripping action, depending on which of the cam levers 30 once pivots in its respective position.

The rubber sealing element 6 is virtually any suitable elastomeric material, but any or all components of the other attachments may be conventional molded plastic.

Consider proceeding from the position shown in FIG. 1b to the position in FIG. 1c. When the cam lever 30 is swiveled 180 degrees, it causes the lifting core 10 to move upwards via the cam lift ring 12, so that the rubber seal 6 is axially arranged between the peripheral projection 15 of the lifting core 10 and the fixing element 9. Is compressed into. The resulting radial outward deformation of the rubber seal 6 causes the rubber seal to form a sealing arrangement with the cylindrical portion 5 of the shroud 4, where the rubber seal internally grips and seals the wall of the mouth 60 of the container. To do.

The degree of sealing / gripping action is
It depends, at least in part, on the placement of the wall of the container mouth 60 between the deformed rubber sealing element and the outer cylindrical portion 5 of the shroud 4. Ideally, the arrangement is such that as the container mouth is internally sealed and the mouth is tightly gripped, it forms a safe and robust product protection connection.

Preferably, the wall of the container mouth is shown in FIGS.
Incline toward the open orifice as shown at c. This configuration provides an improved gripping and sealing action of the deformed rubber sealing element 6 cooperating with the cylindrical portion 5 of the shroud 4.

In order to release the attachment from the fixed state at the mouth of the container as shown in FIG. 1c, the cam lever device may simply be operated in reverse, so that the attachment is in the state shown in FIG. 1b. Once again secured, the attachment can simply be lifted over the container mouth.

Next, according to a second embodiment of the present invention shown in FIG. 2a, the main components are a tightening core 74, a rubber seal member 76, a chain ring 82 and a cap 120. Similar to the first embodiment, the cap 120 incorporates a liquid return structure in the form of a radially inner flange 121. The tightening core 74 has a spout 9 in the central passageway passing through the core.
0 is provided. The cap 120 may be secured to the tightening core 74 via threads 86. Tightening core 74
Includes a generally cylindrical portion 75 located outside of the mouth portion 130 of the container onto which the attachment fits. The annular portion 79 of the clamping core constitutes the fixing element against which the elastic sealing member 76 is compressed when the attachment is clamped onto the container.
The clamping core further includes a plurality of circumferentially spaced clamping elements 85, each of which is pivotable in relation to the cylindrical portion 75. The swivel means is preferably formed by each clamping element 85 and its integral cylindrical part 75, the swivel means having a thin-walled material defining the boundary between these two elements, The possibilities are provided by the elasticity and / or flexibility of the material in its thin area.

The tightening core 74 is preferably made of a plastic material (which material is the tightening element 85 and the cylindrical portion 7).
5 to provide the desired elastic pivoting connection between the two) and are integrally molded as usual.

As can be seen more clearly in FIGS. 2c and 2d, each clamping element 85 has a projection 8 on its radial and inward side.
5a, the projections are generally like radially inwardly projecting ribs, or similar projection elements of arbitrary cross section. The ribs on each element 85 preferably cooperate with corresponding recesses,
The recess is a recess or neck in the wall of the container mouth onto which the attachment is secured, thus allowing the mouth of the container to be gripped externally by each clamping element 85.

In this embodiment, a plurality of fastening elements 8
5 are provided over the entire periphery of the tightening core 74. However, the element 85 may be arranged only in selected positions around its perimeter. Nevertheless, in general, sufficient clamping elements should be provided so that the container on which the attachment is secured should be grasped sufficiently firmly, and that the number, position, and even shape of the clamping elements should be adequately secure. Should be selected as desired to give.

Thus, the preferred recesses, recesses or necks in the wall of the container described above cooperate with the closure element 85 along the periphery of the container mouth and in the manner described above with the mouth.
To the desired range.

To a lesser extent, but not within the scope of the embodiment, the container mouth can be provided with recesses, recesses or even necks which are not individual. The gripping action required in such a case is due to friction, which is between the container material and the clamping element and / or between the container material and the clamping element embedding material and / or of the container wall material. This is due to deformation.

As shown in FIGS. 2c and 2d, the seal member 76 includes a generally cylindrical portion 76a and an integral, generally annular portion 76b. Preferably FIG. 2a
As shown in FIG. 5, the annular portion 76b of the seal member 76 is provided with a circular recess 77, and the annular portion 79 of the tightening core 74 is provided with a corresponding circular protrusion 77a.

In a second embodiment of the attachment of the present invention, the means for deforming the sealing member 76 in cooperation with the clamping element 85 of the clamping core 74 into a grip and sealing relationship is a locking ring 82. Is also preferably made of molded plastic material. Locking ring 82
Includes threads 83 which cooperate with corresponding threads 83 provided on the outside of the cylindrical portion 75 of the clamping core 74. When the locking ring 82 is screwed downwards on the clamping core 74, the clamping element 85, which is normally projecting radially outwards as shown in FIG. 2a, is pressed radially inward. Tightening thus occurs between the fastening elements and also between the sealing member 6 and the container mouth 130 on which the attachment is fixed. The normally outwardly oriented clamping element 85 as shown in FIG.
Although the container mouth wall can be easily inserted into the space, which space is provided before the operation of the tightening mechanism with the tightening element 85.
And a cylindrical portion 76a of the seal member 76.

FIG. 2c shows that the locking ring 82 tightens the core 7
4 shows the state immediately before being lowered by screwing it up, and FIG.
d represents the condition of the device after the locking ring 82 has been screwed in to clamp and seal the attachment over the container mouth. As shown in FIG. 2d, the tightening element 85
Grasps a recessed wall outside the mouth 130 of the container, which wall is clamped between the clamping element 85 and the cylindrical portion 76a of the sealing element 76. Annular portion 7 of sealing element 76
6b is also under compression in this condition, so that the annular portion substantially fills the void between the top of the container mouth and the annular portion 79 of the clamping core 74. This provides a sufficient sealing action and avoids leakage of the contents of the container via the attachment connection.

As shown in FIGS. 2c and 2d, an annular flange 131 is preferably provided on the top of the container mouth.
In the condition that the attachment is locked as shown in Fig. 2d,
The flange supports the gripping and sealing action of the seal member 76.

In order to remove the attachment from the mouth of the container, the locking ring 82 is unscrewed to disengage the tightening mechanism, which returns the attachment to the state of FIG. 2c. In this returned state, the clamping element 85 has been released from the gripping engagement with the container mouth, thus allowing the attachment to be lifted out of the mouth.

3a to 3c show a third embodiment according to the present invention. This form of the device includes, as major components, a conventional elastomer seal element 146, a clamp body 144 and a threaded cap 190 (with liquid return form).

In this embodiment, the main tightening body 144 is simpler than the corresponding group of ingredients in the embodiment of FIGS. 2a-2d and, as mentioned above, the spout 16.
It can be conventionally formed by integral plastic molding, preferably containing 0. As clearly shown by FIG. 3b, the downward extension from the clamping body 144 terminates in a peripheral shoulder 147, on which the usual circular elastic element 146 is held. An inner step 149 holds the sealing element 146 between it and the peripheral shoulder 147, as a fastening element as already described. The sealing element 146 is compressed against this inner step 149 when the attachment is secured over the container mouth 200.

In addition, the clamping body 144 has a generally cylindrical outer portion 145, which abuts the wall of the container mouth when the attachment is located on the container mouth. The outer portion 145 of the tightening body 144 has a plurality of tightening arms 148 at a plurality of locations around its periphery.
Is provided. Preferably such a clamping arm 14
Two are arranged on the opposite side with respect to the diameter of the tightening body 144. Two or more arms 148 may be arranged, for example three or more, as desired, and they are preferably evenly spaced around the periphery of the clamping body 144.

Tightening arm 148 and main tightening body 1
Elasticity is still supported because of the elasticity of the integral connection with 44 and by the placement of the keyhole slot 151 on each side, for example at the point where each clamping arm 148 joins the main clamping body 144. .. Moreover, in this configuration no additional pressing means are necessary so that the required tightening of the attachment onto the container mouth is the lower distal end of each tightening arm 148 formed by the radially inwardly projecting legs 155. Achieved by a portion, the protruding leg is adapted to fit in a lower position of a corresponding radially outwardly projecting shoulder 210 formed in the container mouth wall. The shoulder 210 can preferably be formed as a neck or partial peripheral recess in the container wall.

As noted in the first embodiment of FIGS. 1a-1c, in the third embodiment of the attachment, the container mouth wall may preferably be configured to provide the non-cylindrical portion 202. , The seal member 146 may be at least partially pressed against this non-cylindrical portion, thus assisting the gripping and sealing action of the device.

When the attachment to the container mouth 200 of the third embodiment is in the position just prior to the deformation of the sealing element 146, the arrangement of the components of the attachment is shown in FIG. 1b.
The sealing element is in a generally relaxed cylindrical state and is retained between the inner step 149 and the peripheral shoulder 147 of the tightening body 144. The lower edge of the sealing element 146 abuts the inner wall of the shoulder 210, which is the inner step 149 and the shoulder 2.
Since it is located between the inner wall of 10 and the sealing element,
The attachment undergoes compression as it is pressed down onto the container mouth.

As shown in FIG. 3b, when the attachment is in its proper gripping and sealing state,
The sealing element 146 grips the wall of the container mouth between it and the clamping element 148 and also seals the container mouth to prevent leakage of the contents from the container mouth. When the attachment is pushed down onto the container to reach the conditions shown in Figure 3b, the clamping arm 148 will move the sealing element 1
46 is pushed well past the wider portion of the container neck against which it rests, and thus the clamping leg 155.
Can be snap fit into the recess underneath the shoulder 210 of the container neck, thereby securing the attachment in place.

Thus, in this embodiment, the size and shape of the container neck should be carefully selected to match the structure of the attachment clamping arm 148, thus achieving proper gripping and / or sealing.

Referring to FIGS. 4a-4d, there is shown a fourth embodiment of the present invention. The arrangement here is the shroud 222, the elastomer seal member 216, the spinner washer 218, and the tightening body 230. The body component includes an integrally connected closure cap 234 (with a liquid return feature). As before, the body portion 214 of the tightening body 230 has a spout 232.

The shroud 222 includes a generally cylindrical portion 223 that has threads 22 on its inner surface.
6 and the thread is configured to engage a corresponding thread 246 formed on the exterior surface of the mouth 240 of the container, over which the device fits. ..

The lower extension of the body portion 214 of the tightening body 230 has a peripheral shoulder 21 which holds the frustoconical portion 216a of the elastomeric seal member 16 thereon as previously described.
End at 5. Integral with this frustoconical portion 216a is a substantially flat and annular portion 216. A spinner washer 218 is mounted on the annular portion, at least preferably on a portion thereof. This washer reduces the friction between the seal member 216 and the upper annular portion 224 of the shroud 222 because the shroud undergoes rotation as it is screwed downwardly over the container mouth.

Preferably, body portion 214 of clamping body 230 is pivoted in cooperation with peripheral ribs 215a, which ribs assist in retaining elastomeric member 216 when the attachment is not installed on the container, The ribs also help prevent over-compression of the seal member 216 (and thus over-tightening of the shroud 222) as the shroud 222 is threaded down onto the container mouth.

The action of screwing the shroud 222 onto the mouth 240 of the container causes the mouth of the container to be clamped between the threads 226 of the shroud 222 and the frustoconical portion 216a of the seal member 216. At the same time, the effect of additional tightening is to provide threads 226 and upper annular portion 2 of shroud 222.
It occurs between 24 and. This additional action favors that the wall of the container mouth 240 terminates in the form of an annular flange, as shown in FIG.
The annular portion 216b of No. 6 is abutted in cooperation with the friction reducing spinner washer.

A fifth embodiment according to the present invention is shown in FIGS.
The major components of this device are shown in FIG.
~ Similar to the component of Figure 1c. The main components of the attachment here are the tightening core 260 (including the spout 270 integrally), the cylindrical elastic seal member 256, the clip ring 258, the compression ring 255 and the threaded cap 300 (selectively liquid return). With internal flange parts)
Composed of etc.

With particular reference to FIGS. 5a and 5c, a clamping core 260 having a cavity has a lower platform 265 on which a substantially cylindrical element 256 (when unstressed) is provided. Held in. The thread 267 provided on the core causes the clip ring 25 to
8 engages with corresponding threads on the inner wall of the lower portion 261 of
Both components of the core and the clip ring have a seal member 2 between them.
Make sure that 56 is sandwiched in between. Sealing member 25
6 has a plurality of or one peripheral compression ridge 254 (FIG. 5c) formed on the inside of the compression ring 255.
Held by the clip ring 25.
8 extends through each of the windows 254a in eight.

At least two locations on the periphery of the clip ring 258 are provided with respective clip elements 262,
The element includes a clip ring 258 via an elastic unitary connection.
Is bound to the main body of. As with all of the key components of the embodiment regarding attachment (although the elastic seal member 256 made by any conventional method is, of course), the clip ring 258 is preferably formed as a one-piece plastic molding. Preferably two diametrically opposed clip elements 262 are provided on the clip ring 258, although more elements may be provided if desired. Each of the clip elements 262 is a compression ring 2.
Corresponding to a locking opening 257 provided in 55 through which a radially outward projection on each corresponding clip element 262 extends, a compression ring 255 and a clip ring 258.
Will project when they are in their locked state.

FIG. 5c shows the attachment of this embodiment at a position above the container mouth 310, and just before the clamping mechanism deforms the seal member 256 against the outer element of the device in a gripping and sealing relationship. Represents the state. The device includes a substantially cylindrical portion 253 of compression ring 255. In the illustrated state, each locking element 262 is elastically bent radially inward by the inner wall of the generally cylindrical portion 253 of the compression ring 255. At this point, the compression protrusion 254 located inside the compression ring 255 contacts the upper edge of the seal member 256. Then, in order to effectively tighten the attachment from this position, the compression ring 2
55 may simply be pressed down with respect to the clamping core 260 in the container mouth to bring it to the state of FIG. 5d.

In this way, in the latter state, the compression ridge 254 compresses the sealing member 256 to deform it radially outward, and the sealing member 254 is moved inside the ridge and the wall of the container opening 310. Tightening is carried out by the embracing compression ring 255 and the cylindrical portion 253. As a result of this movement, the locking opening 257 in the compression ring 255 and the outer protruding portion of the clip element 262 are properly aligned, which causes the clip element 262 to move under their elasticity to those shown in FIG. 5d. It will return to its normal position like a spring. Under this condition, the clip element 262 locks the compression ring 255 in place and prevents its reverse movement, which is pushed by the elasticity of the seal member 256.

Thus, in the state shown in FIG. 5d, the attachment is firmly and sealingly clamped onto the container mouth 310, while the clip element 262 locks the attachment in that state. To disengage the attachment, the clip element 262 is forced radially inward by a simple manual operation. This allows the element to no longer interfere with the relative upward movement of the compression ring 255, where it is now free to lift upwards, and the clip ring 258.
And thus seal member 2 as shown in FIG. 5c.
Bring 56 to a stress-free state. The attachment under this condition can easily lift the attachment to the outside of the container mouth.

The open mouth of the container to which the attachment of the present invention can be applied may suitably be formed with a lip or radial flange as shown at 65 in FIGS. 1a-1c. This configuration not only helps position the attachment at the open container neck, but is useful, for example, to provide a product-filled container with a foil seal under which such product-filled containers are individually Available for sale.

After obtaining such a container with product, the foil seal is broken and the attachment according to the invention located on the open container part and the clamping device operated to secure the attachment to the container are therefore Closed /
A spout may be provided to allow the user to safely and easily dispense the contents from the container, as well as store the container under safe and sealed conditions.

When all the product is consumed and the empty container needs to be discarded, the attachment can be easily removed and transferred to another container in need thereof. The attachment of the present invention thus results in a simpler and cheaper manufacture of product filled containers and also reduces waste.

The contents of the container to which the attachment of the present invention is applied are not limited. Liquids such as detergents are especially suitable, but powders and other solids can be used for this as well as many other product forms.
