Description

  The present invention relates to a liquid absorption pack that absorbs liquid and a liquid processing apparatus using the same.

  In recent years, treatment of oil and solid fats and oils contained in waste liquid has become a problem in general households and various industries. Hereinafter, oil and solid fats and oils are referred to as fats and oils. Therefore, a restaurant that operates a restaurant or a restaurant is provided with a grease interceptor as a device for preventing the fat and oil in the drainage from flowing directly into the sewage. If the grease interceptor is not frequently cleaned, the fat and oil contained in the drainage liquid will generate odors and pests, block the sewer pipe, and deteriorate the function of the water treatment center. In order to prevent this, the relevant authorities are instructed to physically remove the fat and oil contained in the drainage once a day.

  When the oil and fat floating in the grease interceptor is manually picked up or separated and recovered by the liquid processing device, some kind of container that prevents liquid leakage is required to dispose of the oil and fat containing the liquid as it is. . In order to easily dispose of the fat and oil containing the liquid without requiring such a container, it is preferable to absorb the liquid in the solid matter.

  Therefore, an absorption sheet that absorbs liquid has been developed. A nonwoven fabric or the like is used as a material for such an absorbent sheet (see Patent Document 1). Powdered absorbents have also been developed.

When separating fats and oils using a separator, in order to remove the liquid from the separated fats and oils, the above absorbent sheet is installed in the collection container, and the liquid contained in the fats and oils is absorbed in the collection container. Absorb to sheet. Thus, the absorption sheet which absorbed the liquid contained in fats and oils can be discarded.
JP 7-108170 A

  However, since the above absorbent sheet has a low absorption capacity, a large area absorbent sheet is required when a large amount of oil and fat is discarded. Thereby, the cost for discarding fats and oils increases. Moreover, when using such an absorption sheet of a large area for a liquid processing apparatus, the collection | recovery container for storing the separated fats and oils enlarges.

  When using an absorbent, it is necessary to enclose the absorbent in a bag to prevent the absorbent from scattering. The absorbent expands by absorbing the liquid. Accordingly, in order to maximize the absorption capacity of the absorbent, a bag for encapsulating the absorbent must be formed large. This complicates handling of the bag containing the absorbent and increases the cost.

  An object of the present invention is to provide a liquid absorption pack that can be miniaturized and has excellent liquid absorbency, and a liquid processing apparatus using the same.

  (1) The liquid absorption pack according to the first invention includes an absorbent that absorbs liquid and a bag that contains the absorbent, and at least a part of the bag is decomposed by contact with the liquid.

  In the liquid absorption pack according to the first invention, when the bag comes into contact with the liquid, at least a part of the bag is decomposed. Further, the absorbent expands by absorbing the liquid and leaks out from the disassembled portion of the bag.

  In this case, the absorption expansion of the absorbent is not inhibited by the bag. Thereby, the absorbent can absorb a large amount of liquid. Therefore, the absorbent capacity of the absorbent can be maximized with a small bag.

  Moreover, since a bag can be reduced in size, a liquid absorption pack is not bulky and is easy to store, transport and handle.

  (2) The bag may be formed of a liquid permeable material. In this case, the liquid passes through the bag and is absorbed by the absorbent in the bag, and at least a part of the bag is decomposed. Thereby, since the absorption expansion of the absorbent proceeds more rapidly, a large amount of liquid can be reliably absorbed in a short time.

  (3) The bag may be formed of a liquid-impermeable material. In this case, even if the material of the bag is liquid-impermeable, the liquid flows into the bag from the decomposed portion of the bag by disassembling at least a part of the bag by contact with the liquid. The liquid that has flowed into the bag is absorbed by the absorbent. Since the absorption expansion of the absorbent is not hindered by the bag, the absorbent can absorb a large amount of liquid.

  (4) At least a part of the bag may be dissolved by contact with the liquid. In this case, at least a part of the bag is decomposed by dissolving at least a part of the bag by contact with the liquid. As a result, the absorbent that has absorbed the liquid and expanded has leaked out of the bag. Therefore, the absorption expansion of the absorbent is not hindered by the bag.

  (5) The bag may be formed from a material containing starch. In this case, the starch solidifies in the dry state and dissolves upon contact with the liquid. Thereby, when the bag comes into contact with the liquid, at least a part of the bag is easily dissolved, and the absorbent leaks out of the bag.

  (6) The bag may be formed from a material containing pulp. In this case, the pulp is bonded with such a strength that leakage of the absorbent is reliably prevented and the pulp is separated by contact with the liquid. Thereby, when it contacts with a liquid, at least one part of a bag melt | dissolves and an absorber leaks out of the bag.

  (7) The absorbent may be in powder form. In this case, the absorbent leaked by the bag decomposition can enter the narrow space. Thereby, the liquid in a narrow place can be absorbed by the absorbent.

  In addition, the surface area of the absorbent is increased when the absorbent is formed in a powder form as compared with the case where the absorbent is formed in a sheet form or a lump form. Thereby, the absorption capacity of the absorbent is improved.

  (8) The absorbent may include pulp. In this case, the pulp is highly absorbent and lightweight. Therefore, the absorption capacity of the liquid absorption pack is high, and handling becomes easy. Further, since the pulp is inexpensive, the cost of the liquid absorption pack can be reduced.

  (9) The absorbent may include a polymeric absorbent. In this case, a large amount of liquid can be reliably absorbed by the polymer absorbent.

  (10) The bag may have an adhesive portion, and the adhesive portion may be separated by contacting with a liquid. In this case, the adhesive part is separated by contact with the liquid, and at least a part of the bag is decomposed. As a result, the absorbent that has absorbed the liquid and expanded has leaked out of the bag. Therefore, the absorption expansion of the absorbent is not hindered by the bag.

  (11) The bonding portion may be bonded with a liquid-soluble adhesive. Here, “liquid solubility” refers to a property of dissolving by contact with a liquid. In this case, the adhesive at the bonding portion is dissolved by contact with the liquid, and at least a part of the bag is decomposed. As a result, the absorbent that has absorbed the liquid and expanded has leaked out of the bag. Therefore, the absorption expansion of the absorbent is not hindered by the bag.

  (12) The adhesive portion may be sewn with a liquid-soluble thread. In this case, the thread of the bonding portion is dissolved by contact with the liquid, and at least a part of the bag is decomposed. As a result, the absorbent that has absorbed the liquid and expanded has leaked out of the bag. Therefore, the absorption expansion of the absorbent is not hindered by the bag.

  (13) The bag may have a binding portion, and the binding portion may be separated by contacting with the liquid. In this case, the binding portion is separated by contact with the liquid, and at least a part of the bag is disassembled. As a result, the absorbent that has absorbed the liquid and expanded has leaked out of the bag. Therefore, the absorption expansion of the absorbent is not hindered by the bag.

  (14) The binding portion may be bound by a liquid-soluble binding tool. In this case, the binding tool of the binding part is dissolved by contact with the liquid, and at least a part of the bag is decomposed. As a result, the absorbent that has absorbed the liquid and expanded has leaked out of the bag. Therefore, the absorption expansion of the absorbent is not hindered by the bag.

  (15) A liquid processing apparatus according to a second aspect of the present invention is a separation tank that separates water and fats and oils in drainage, a collection container, and a collection unit that collects the fats and oils separated in the separation tank in a collection container. And the liquid absorption pack according to the first invention provided in the recovery container.

  In the liquid processing apparatus according to the second aspect of the invention, the waste liquid stored in the separation tank is separated into water and oil and fat. The separated fats and oils are recovered from the separation tank to the recovery container by the recovery means. The liquid contained in the oil and fat is absorbed by the liquid absorption pack in the collection container.

  In this case, in the liquid absorption pack, when the bag comes into contact with the liquid, at least a part of the bag is decomposed. Further, the absorbent expands by absorbing the liquid and leaks out from the disassembled portion of the bag.

  In this case, the absorption expansion of the absorbent is not inhibited by the bag. Thereby, the absorbent can absorb a large amount of liquid. Therefore, the absorbent capacity of the absorbent can be maximized with a small bag.

  Moreover, since a bag can be reduced in size, a liquid absorption pack is not bulky and is easy to store, transport and handle.

  According to the present invention, the absorption expansion of the absorbent is not inhibited by the bag, and the absorbent can absorb a large amount of liquid. Therefore, the absorbent capacity of the absorbent can be maximized with a small bag.

  Hereinafter, a liquid absorption pack according to an embodiment of the present invention will be described with reference to the drawings.

(1) First Embodiment FIG. 1 is an external perspective view showing a liquid absorption pack according to a first embodiment of the present invention.

  As shown in FIG. 1, a fine powdery absorbent 2 is placed between two water-soluble sheets 1, and adhesive portions 11 a, 11 b, 11 c, and 11 d along the four sides of the water-soluble sheet 1 are formed. Glued. Thereby, the liquid absorption pack 10 in which the absorbent 2 is filled in the bag 3 is formed. Here, the water-soluble sheet 1 refers to a sheet that dissolves by contact with a liquid such as water or oil. The amount of the absorbent 2 filled in the bag 3 is, for example, about 5 g to about 10 g.

  The bonding portions 11a to 11d are bonded by various bonding methods such as sewing, thermocompression bonding, or bonding using an adhesive. Further, a water-soluble thermoplastic sheet may be inserted between the two water-soluble sheets 1 and heat may be applied to the bonding portions 11a to 11d. Here, the thermoplastic sheet melts when heat is applied, and cures when the temperature decreases. Thereby, the adhesion parts 11a-11d of the water-soluble sheet 1 are adhere | attached. Such a bonding method using a thermoplastic sheet is generally called heat sealing.

  The water-soluble sheet 1 of the bag 3 is made of a material that prevents the absorbent 2 from permeating in a dry state and allows liquid to permeate in a wet state. Examples of the material of the water-soluble sheet 1 include a mixture of starch and pulp. Starch solidifies in the dry state and dissolves upon contact with the liquid.

  The absorbent 2 is made of a material that can absorb a large amount of liquid and hold the absorbed liquid. Examples of the material of the absorbent 2 include cotton-like pulp. In addition, you may mix and use polymer absorbents, such as a silicone type, a polyester type, a polyamide type, or a polyacrylate, with cotton-like pulp.

  The bag 3 is formed by bending one water-soluble sheet 1 and adhering the adhesive portions 11a, 11b, and 11c along the three sides while the absorbent 2 is placed therebetween. Also good.

  FIG. 2 is a cross-sectional view showing stepwise changes in the shape of the liquid absorbent pack 10 when the liquid is absorbed by the liquid absorbent pack 10 of FIG. Here, the liquid is, for example, a mixed liquid of water and oil.

  When the liquid comes into contact with the liquid absorption pack 10, as shown in FIG. 2A, the liquid wets the bag 3 and permeates the bag 3 and is absorbed by the absorbent 2. Thereby, as shown in FIG. 2 (b), a part or the whole of the bag 3 is dissolved, so that the bag 3 is decomposed, and the absorbent 2 absorbs the liquid and expands. When the liquid is further supplied, as shown in FIG. 2C, the absorbent 2 further expands and absorbs the liquid until the absorbent 2 reaches a saturated state.

  Thus, in the liquid absorption pack 10 of 1st Embodiment, it melt | dissolves when the bag 3 with which the absorbent 2 was filled contacts a liquid. Thereby, when the liquid is absorbed by the liquid absorption pack 10, the absorption expansion of the absorbent 2 is not inhibited by the bag 3. Therefore, the absorbent 2 can absorb a large amount of liquid. As a result, the absorbent capacity of the absorbent 2 can be maximized with the small bag 3. Therefore, a large amount of liquid can be easily discarded in a state where it is absorbed by the absorbent 2.

  Moreover, since the bag 3 can be reduced in size, the liquid absorption pack 10 is not bulky, and storage, transportation, and handling become easy.

  The absorbent 2 can be formed into a fine powder. Therefore, the absorbent 2 leaked by the dissolution of the bag 3 can enter the narrow space. As a result, the absorbent 2 can absorb the liquid in the narrow space.

  Furthermore, the surface area of the absorbent 2 is increased when the absorbent 2 is formed in a powder form as compared with the case where the absorbent 2 is formed in a sheet form or a lump form. Thereby, the absorption capacity of the absorbent 2 is improved.

  FIG. 3 is a perspective view for explaining an example of the manufacturing method of the liquid absorbent pack 10 of FIG.

  As shown in FIG. 3, two long water-soluble sheets 1 having the same size are prepared. One water-soluble sheet is divided into a plurality of rectangular areas as indicated by dotted lines, and an appropriate amount of absorbent 2 is placed in each area. Thereafter, another water-soluble sheet 1 is overlaid on the water-soluble sheet 1. In this state, the two water-soluble sheets are bonded by the above method at the bonding portion 11 along the dotted line.

  Finally, the two water-soluble sheets 1 are cut along the dotted line. Thereby, a plurality of liquid absorption packs 10 shown in FIG. 1 are manufactured simultaneously. According to this manufacturing method, mass production of the liquid absorption pack 10 is possible.

(2) Second Embodiment FIG. 4 is an external perspective view showing a liquid absorption pack according to a second embodiment of the present invention.

  The liquid absorption pack 10 shown in FIG. 4 is different from the liquid absorption pack 10 shown in FIG. 1 in the following points.

  In the liquid absorption pack 10 of FIG. 4, the bag 3 a is formed by bonding two water-insoluble sheets 1 a with the water-soluble adhesive 4 at the bonding portions 11 a to 11 d. The absorbent 2 is filled in the bag 3a.

  The bag 3a is made of a material that prevents the absorbent 2 from permeating in a dry state and allows liquid to permeate in a wet state. The same material as that of the first embodiment is used for the absorbent 2. Examples of the water-soluble adhesive 4 include a paste mainly composed of starch. Moreover, you may adhere | attach the adhesion parts 11a-11d by the heat seal using a water-soluble thermoplastic sheet similarly to the liquid water absorption pack 10 of 1st Embodiment.

  Note that a water-soluble thread may be used instead of the water-soluble adhesive 4. Examples of the water-soluble yarn include yarn made of pulp and starch. In this case, the bag 3a is formed by stitching the adhesive portions 11a to 11d with a water-soluble thread.

  FIG. 5 is a cross-sectional view showing stepwise changes in the shape of the liquid absorbent pack 10 when the liquid is absorbed by the liquid absorbent pack 10 of FIG.

  When the liquid comes into contact with the liquid absorption pack 10, the liquid wets the bag 3 a and is absorbed by the absorbent 2 as shown in FIG. Further, the liquid comes into contact with the adhesive 4. Thereby, as shown in FIG.5 (b), while the adhesive 4 of the adhesion parts 11a-11d melt | dissolves, while the bag 3a decomposes | disassembles, the absorber 2 absorbs a liquid and expand | swells. When the liquid is further supplied, as shown in FIG. 5C, the absorbent 2 further expands and absorbs the liquid until the absorbent 2 reaches a saturated state.

  Thus, in the liquid absorption pack 10 of 2nd Embodiment, it melt | dissolves when the adhesive agent 4 in the adhesion parts 11a-11d of the bag 3a contacts with a liquid. Thereby, like the liquid absorption pack 10 of 1st Embodiment, when a liquid is absorbed by the liquid absorption pack 10, the absorption expansion | swelling of the absorbent 2 is not inhibited by the bag 3a. Therefore, the absorbent 2 can absorb a large amount of liquid. As a result, the absorbent capacity of the absorbent 2 can be maximized with the small bag 3a. Therefore, a large amount of liquid can be easily discarded in a state where it is absorbed by the absorbent 2.

  Moreover, since the bag 3a can be reduced in size, the liquid absorption pack 10 is not bulky, and storage, transportation, and handling become easy.

  The absorbent 2 can be formed into a fine powder. Therefore, the absorbent 2 leaked from the bag 3a can enter the narrow space. As a result, the absorbent 2 can absorb the liquid in the narrow space.

  Furthermore, the surface area of the absorbent 2 is increased when the absorbent 2 is formed in a powder form as compared with the case where the absorbent 2 is formed in a sheet form or a lump form. Thereby, the absorption capacity of the absorbent 2 is improved.

  Further, instead of the water-soluble adhesive 4, an adhesive or an adhesive tape whose adhesive strength is reduced by contact with a liquid may be used. In this case, the adhering portions 11a to 11d are peeled off when the absorbent 2 absorbs the liquid and expands.

  Moreover, the liquid absorption pack 10 which concerns on 2nd Embodiment can be manufactured with the manufacturing method similar to the liquid absorption pack 10 which concerns on 1st Embodiment.

  In this case, the water-insoluble sheet 1a is used instead of the water-soluble sheet 1 in FIG. Further, the bonding part 11 is bonded by a water-soluble adhesive, thread, thermoplastic sheet or the like.

  In addition, in the liquid absorption pack 10 of 2nd Embodiment, you may use the water-soluble sheet 1 similar to 1st Embodiment instead of the water-insoluble sheet 1a. In this case, the bag 3a is more easily disassembled by contact with the liquid.

(3) Other Embodiments FIG. 6 is an external perspective view showing another example of the liquid absorption pack 10.

  In the liquid absorption pack 10 of FIG. 6A, the bag 3 is formed in a circular shape. In this case, the liquid absorption pack 10 is formed by adhering the adhesive portion 11e along the peripheral edge of the water-soluble sheet 1 with the absorbent 2 sandwiched between the two circular water-soluble sheets 1. Is done.

  The shape of the liquid absorption pack 10 is not limited to a quadrangle or a circle, and can be formed in an arbitrary shape such as an ellipse or a triangle.

  6B, the absorbent 2 is wrapped with the water-soluble sheet 1, and a predetermined portion of the water-soluble sheet 1 is bound with a binding tool such as a string or a rubber band so that the absorbent 2 does not leak out. . In this case, the binding tool is preferably made of a water-soluble material.

  In the liquid absorbent pack 10 of FIG. 6C, one side of the folded water-soluble sheet 1 opens without being bonded. A bent portion 11f is provided on one side of the opening of the bag 3, and a convex insertion portion 11g is provided on the bent portion 11f. An insertion hole 11h is provided on the other side. In this case, after the absorbent 2 is filled in the bag 3, the bent portion 11f is bent so as to cover the opening, and the insertion portion 11g is inserted into the insertion hole 11h.

  In the liquid absorption pack 10 shown to Fig.6 (a)-(c), it melt | dissolves when the bag 3 with which the absorber 2 was filled contacts a liquid. Thereby, when the liquid is absorbed by the liquid absorption pack 10, the absorption expansion of the absorbent 2 is not inhibited by the bag 3. Therefore, the absorbent 2 can absorb a large amount of liquid. As a result, the absorbent capacity of the absorbent 2 can be maximized with the small bag 3. Therefore, a large amount of liquid can be easily discarded in a state where it is absorbed by the absorbent 2.

  Moreover, since the bag 1 can be reduced in size, the liquid absorption pack 10 is not bulky, and storage, transportation, and handling become easy.

  The absorbent 2 can be formed into a fine powder. Therefore, the absorbent 2 leaked by the dissolution of the bag 3 can enter the narrow space. As a result, the absorbent 2 can absorb the liquid in the narrow space.

  Furthermore, the surface area of the absorbent 2 is increased when the absorbent 2 is formed in a powder form as compared with the case where the absorbent 2 is formed in a sheet form or a lump form. Thereby, the absorption capacity of the absorbent 2 is improved.

  In addition, the liquid absorption pack 10 of Fig.6 (a)-(c) fills the bag 3 which consists of the water-soluble sheet 1 with the absorbent 2 similarly to the liquid absorption pack 10 of 1st Embodiment. Although formed, instead of the bag 3, it may be formed by filling the absorbent 2 in the bag 3 a made of the water-insoluble sheet 1 a as in the liquid absorption pack 10 of the second embodiment.

  In this case, in the liquid absorption pack 10 shown in FIGS. 6A to 6C, a water-soluble adhesive, a binding tool, or a thread is used. As a result, as in the second embodiment, the adhesive, binding tool, or thread is dissolved by contact with the liquid, so that the absorbent capacity of the absorbent 2 can be maximized with the small bag 3a. Can do.

  In the liquid absorption pack 10 of the above embodiment, when the absorbent 2 is filled in the bag 3 made of the water-soluble sheet 1, the bag 3 is dissolved by contact with the liquid, The tie or thread may not be water soluble.

  In addition, the amount of the absorbent 2 filled in the liquid absorption pack 10 of the above embodiment is not limited to the above embodiment, and is appropriately determined according to the amount of liquid to be absorbed and the like. Further, the size of the liquid absorption pack 10 is appropriately set according to the amount of the absorbent 2 and the like. In particular, in the liquid absorption pack 10 of FIG. 6C, the user can arbitrarily adjust the amount of the absorbent 2 filled in the bag 3 by removing the insertion portion 11g from the insertion hole 11h. it can.

  Moreover, although the said embodiment uses the powdery absorbent 2, the shape and magnitude | size of the absorbent 2 are not limited, Arbitrary shapes and magnitude | sizes, such as small piece form, cotton form, or a granular form, are not limited. Absorbents can be used.

  Moreover, in the said embodiment, although the material which a liquid permeate | transmits is used for the water-soluble sheet | seat 1 and 1a, it is not limited to this, Liquids, such as a vinyl which does not permeate | transmit a liquid in a dry state and a wet state A sheet made of an impermeable material may be used.

  In the case where a water-insoluble and liquid-impermeable sheet is used, the adhesive portion is bonded or bound by a water-soluble adhesive, thread, thermoplastic sheet, binding tool or the like. Thereby, an adhesion part decomposes | disassembles by contact with a liquid, and a liquid flows in in a bag from the decomposed | disassembled part. The liquid that has flowed into the bag is absorbed by the absorbent. Since the absorption expansion of the absorbent is not hindered by the bag, the absorbent can absorb a large amount of liquid.

Thereby, the region 26 </ b> C is filled with the water 35. The water 35 in the region 26 </ b> C flows into the drainage pipe 25 from the upper part of the region 26 </ b> C and flows out from the drainage pipe 25 to the water storage tank 23.

  On the other hand, above the region 26A, the pusher 27 driven by the pusher drive unit 27a is located above the separation region 26A of the oil / fat separation tank 26 from the partition plate 30a side as shown by the arrows in FIGS. It moves to above the discharge duct 28. Thereby, the scraping portion 27b at the lower end of the pusher 27 moves over the inclined surface 261 and onto the discharge duct 28 so as to scratch the oil layer 34 in the region 26A from the partition plate 30a.

  As a result, the oil layer 34 is pushed out from the region 26 </ b> A into the discharge duct 28 via the inclined surface 261. As a result, the oil and fat contained in the oil layer 34 is dropped into the collection bag 32 in the collection container 29 through the discharge duct 28.

  In this manner, the oil and fat components made up of liquid and solid matter are collected in the collection bag 32. The liquid contained in the oil and fat is absorbed by the liquid absorption pack 10 placed in the collection bag 32.

  Subsequently, the pusher 27 is returned to the partition plate 30b by the pusher drive unit 27a, and the same operation as described above is repeated.

  The above series of operations is controlled by a control unit (not shown), and the start and end of the operation are operated by the switch 40 shown in FIG.

(5) Effect of Liquid Treatment Device Using Liquid Absorption Pack In the liquid treatment device 100 of the present embodiment, the liquid contained in the oil and fat is absorbed by the liquid absorption pack 10 placed in the collection bag 32. Thereby, the collection bag 32 can be discarded as it is.

  Moreover, in the liquid absorption pack 10, the bags 3 and 3a containing the absorbent 2 are decomposed by coming into contact with the liquid. Thereby, when the liquid is absorbed by the liquid absorption pack 10, the absorption expansion of the absorbent 2 is not hindered by the bags 3 and 3a. Therefore, the absorbent 2 can absorb a large amount of liquid. As a result, the absorbent capacity of the absorbent 2 can be maximized with the small bags 3 and 3a. Therefore, a large amount of liquid can be easily discarded in a state where it is absorbed by the absorbent 2.

  The absorbent 2 can be formed into a fine powder. Thereby, the liquid that has entered the gap between the solid materials can also be effectively absorbed by the absorbent 2.

  Moreover, since the bags 3 and 3a can be reduced in size, the liquid absorption pack 10 is not bulky and can be easily stored, transported and handled.

  The liquid processing apparatus 100 can also be used in other equipment or containers for storing drainage. In this case, the size and length of the liquid suction pipe 24 and the drainage pipe 25 are appropriately determined depending on the size, shape, location, etc. of the equipment or container.

  Further, the absorption pack 10 can be used not only in the liquid processing apparatus 100 of the above-described embodiment, but also in other processing apparatuses having various structures. Further, the liquid absorption pack 10 alone is used to absorb various liquids. But it can be used.

(6) Correspondence between each component of claim and each part of embodiment In the above embodiment, the oil separation tank 26 corresponds to a separation tank, and a pusher 27, a pusher drive part 27a, a scraping part 27b, The inclined surface 261 and the discharge duct 28 correspond to the recovery means.
