Description

  The present invention relates to a brush for applying a liquid onto an application target.

  BACKGROUND ART Conventionally, in food processing plants and the like, brushes using animal hair have been used to apply liquids such as egg yolk, honey, syrup and sauce to foods such as bread, cookies, cakes and hamburgers. However, in recent years, animal hair materials have not been used for brushes due to food hygiene problems. For example, as shown in Patent Document 1, synthetic resin hair materials are used instead of animal hair materials. It has come to be used.

  As shown in FIG. 7A, the brush 100 disclosed in Patent Document 1 is a hair bundle formed by bundling a main body 101 and a plurality of bristle materials 103 having one end fixed to the main body 101. And a section 102. When the liquid is applied to the food using the brush 100, as shown in FIG. 7 (b), the hair bundle portion 102 that is dipped in the liquid and holds the liquid is pressed against the food 104, and the hair on the food 104 is brushed. By sliding the bundle 102, the liquid held by the hair material 103 of the bundle 102 is applied on the food 104.

JP, 2007-190189, A

  However, if the bristle material 103 of the brush 100 is made of synthetic resin, the liquid cannot be held on the bristle material 103 for a long time due to the high water repellency peculiar to the synthetic resin. Therefore, after soaking the bristle material 103 in the liquid and before bringing the brush 100 to the upper side of the food 104, most of the liquid adhering to the bristle material 103 spills from the bristle material 103. Therefore, it is necessary to immerse the bristle material 103 in the liquid each time the liquid is applied to the food 104, which not only takes time but also a lot of liquid spills between the container containing the liquid and the food 104. There is a problem that it takes time to clean the part where the liquid is spilled.

  Moreover, since the bristle material 103 of the brush 100 of Patent Document 1 has a thin and isotropic cross-sectional shape, it has the flexibility of bending in any direction. Therefore, when the hair bundle portion 102 is pressed against the food 104, the hair material 103 on the side of the hair bundle portion 102 moves backward in the sliding direction 105 of the hair bundle portion 102, as shown in FIG. 7B. Instead, it spreads laterally outside the tufts 102. Therefore, on the food 104 corresponding to the side of the hair bundle 102, the liquid is linearly applied due to the spread hair material 103, which causes a problem that uneven streaks 106 occur. When uneven streaks occur on food, not only the appearance thereof deteriorates but also the taste becomes uneven.

  The present invention has been made in view of the above-described problems, and has an excellent ability to retain a liquid, and to provide a brush capable of suppressing the occurrence of uneven streaks on an application target corresponding to the side of the brush. To aim.

  Hereinafter, a brush according to an embodiment of the present invention will be described with reference to the drawings. However, the embodiment described below is merely an example, and the brush of the present invention is not limited to the following embodiment.

  The brush of the present invention can be used to apply a liquid onto an object to be applied. For example, in a food processing factory or the like, egg yolk, honey or syrup is applied to food (object to be applied) such as bread, cookies, cakes and hamburgers. , It can be advantageously used as a food application for applying a liquid for food (liquid) such as a polishing agent such as sauce and a liquid seasoning. However, the brush of the present invention is not particularly limited as long as it is an application for applying a liquid onto an application target, and can be used for other applications other than food.

  As shown in FIG. 1, a brush 1 according to one embodiment (hereinafter, referred to as a first embodiment) of the present invention is attached to a main body portion 2 having a grip portion 21 and a main body portion 2, and is applied onto an application target. And a synthetic resin coating section 3 for coating a liquid.

  The main body portion 2 is a member to which the coating portion 3 is attached and which is gripped by a human hand or a gripping device of an automatic coating device in order to operate the brush 1. As shown in FIG. 1, the main body 2 of the first embodiment has a grip 21 that is gripped by a human hand or a gripping device of an automatic application device, and the grip 21 is connected to one end side and the other end. It has a mounting part 22 to which the coating part 3 is mounted. In the first embodiment, the grip portion 21 is formed in an elongated handle shape, and is connected to one end side of the mounting portion 22. However, the main body part 2 is not limited to the embodiment shown in FIG. 1 as long as the application part 3 can be attached and the main body part 2 can be gripped by a human hand or a gripping device of an automatic coating device. Known shapes and materials used for this type of brush can be adopted.

  The application unit 3 is a member that is formed of a flexible synthetic resin material having flexibility and that applies a liquid onto an application target. As shown in FIG. 1, the application part 3 has its base end side attached to the attachment part 22 of the main body part 2, and its tip end side slidably contacted on the application target to apply the liquid on the application target (FIG. 6 (a) and FIG. 6 (b)). In the present specification, the “base end side” of the coating unit 3 (including the coating plates 31a and 32a described later) means the end portion side adjacent to the main body portion, and the “tip end side” means the base end. It means the opposite end side. In the first embodiment, the base end side of the coating part 3 is attached by being embedded and fixed to the other end side of the mounting part 22 of the main body part 2. However, the application part 3 only needs to be attached to the body part 2 at the base end side, and the attachment method is not particularly limited, such as integrally molding with the body part 2. Further, as the synthetic resin used for forming the coating portion 3, a known synthetic resin material used for a brush made of synthetic resin can be used. For example, from the viewpoint of cost and hygiene, silicone rubber, ethylene propylene diene are used. A synthetic rubber such as rubber (EPDM), nitrile rubber, or fluororubber, or a plastic elastomer such as an olefin elastomer can be preferably used.

  As shown in FIG. 1, the coating unit 3 is arranged so as to face the first coating surface 31 provided with the first coating plate 31 a extending from the main body 2 side and the first coating surface 31, and the main body. The second coating surface 32 is provided with the second coating plate 32a extending from the portion 2 side. The application unit 3 is slid on the application target along the thickness direction D3 of the brush 1 which is the direction in which the first application surface 31 and the second application surface 32 face each other, and thus the liquid is applied on the application target. Is applied (see FIGS. 6A and 6B).

  The first application surface 31 and the second application surface 32 respectively include a plurality of first application surfaces extending in parallel with each other from the main body 2 side, as shown in FIGS. 1, 2A and 2B. Coating plate 31a and a plurality of second coating plates 32a extending in parallel with each other from the main body 2 side. More specifically, each of the first application surface 31 and the second application surface 32 has a plurality of plate-shaped first application plates 31a and a plurality of second application plates 32a, and the plate surface has a brush. 1 is arranged in a line along the width direction D2 of the brush 1 so as to be substantially parallel to the width direction D2 of the brush 1, and is formed in a substantially thin plate shape as a whole. A gap G is formed between each adjacent first coating plate 31a and each adjacent second coating plate 32a. The first application surface 31 and the second application surface 32 are arranged substantially parallel to each other such that the respective thin plate surfaces face each other in the thickness direction D3 of the brush 1. Further, in the first embodiment, the first coating surface 31 and the second coating surface 32 respectively connect the base end sides of the plurality of first coating plates 31a and the second coating plate 32a to each other. The first connecting portion 31b and the second connecting portion 32b are provided. The first application surface 31 and the second application surface 32 are attached to the attachment portion 22 of the main body 2 via the first connecting portion 31b and the second connecting portion 32b. However, if the first application surface 31 and the second application surface 32 are provided with the first application plate 31a and the second application plate 32a, respectively, the first connection portion 31b and the second connection portion 32b are provided. The base end sides of the first application plate 31a and the second application plate 32a may be directly attached to the main body portion 2. Further, although the first application surface 31 and the second application surface 32 each include a plurality of first application plates 31a and a second application plate 32a in the first embodiment, a plurality of first application surfaces 31a and 32a are provided. Each of the plate 31a and the second coating plate 32a may be integrally formed as one coating plate.

  As shown in FIG. 1, the first application surface 31 and the second application surface 32 are connected to each other via a spacer 33 provided between the first connecting portion 31b and the second connecting portion 32b. ing. The first coating surface 31 and the second coating surface 32 are connected via the spacer 33 so that the first coating surface 31 and the second coating surface 32 are connected to each other (especially, the first coating plate 31a). Since the space S is formed between the first coating surface 31 and the second coating plate 32a), it is possible to prevent the first coating surface 31 and the second coating surface 32 from adhering to each other when immersed in the liquid. . However, the coating unit 3 includes the first coating surface 31 and the second coating surface 32 as long as the liquid can be coated on the coating target, and the first coating surface 31 and the second coating surface 32 are , May be directly connected to each other without the spacer 33. Further, the first application surface 31 and the second application surface 32 may extend from the base end side toward the tip end side so that they are close to each other as long as they are arranged to face each other. The first coating surface 31 and the second coating surface 32 are arranged in this manner, and the entire coating portion 3 is formed so as to taper toward the tip side in the thickness direction D3 direction. Since the liquid held between the application surface 31 and the second application surface 32 of the above does not easily flow down from the tip side, the liquid holding capacity of the application unit 3 is further enhanced. Furthermore, since the entire coating part 3 is formed so that the tip ends of the first coating surface 31 and the second coating surface 32 contact each other, the liquid holding capacity of the coating part 3 is further enhanced.

  In the first embodiment, each of the first application surface 31 and the second application surface 32 has a plurality of first application plates 31a, as shown in FIGS. 1, 2A and 2B. And each of the plurality of second coating plates 32a and each of the first connecting portion 31b and the second connecting portion 32b are integrally formed. However, the forming method is not particularly limited, and a method in which the plurality of coating plates 31a and 32a are separately formed and then connected to each other may be adopted. The first application surface 31 and the second application surface 32 are formed of a synthetic resin material such as silicone rubber, but they may be formed of the same synthetic resin material or different synthetic resin materials. May be formed by

  In the first embodiment, the first coating plate 31a and the second coating plate 32a are respectively the first coating plate 31a and the second coating plate 32a as shown in FIGS. 1, 2A and 2B. A cross section substantially perpendicular to the length direction D1 of the brush 1, which is the direction in which the second coating plate 32a extends, is substantially rectangular, and is formed in a plate shape over the entire length from the base end side to the tip end side. The first coating plate 31a and the second coating plate 32a are formed in a plate shape, so that the first coating plate 31a and the second coating plate 32a are easily curved in the thickness direction D3 of the brush 1 (the thickness direction of the coating plates 31a and 32a). The bending of the brush 1 in the width direction D2, which is a direction substantially perpendicular to the length direction D1 of the brush 1 and the thickness direction D3 of the brush 1, is configured to be limited. Therefore, when the application part 3 is slidably contacted on the application target along the thickness direction D3 of the brush 1 in order to apply the liquid on the application target, the first application plate 31a and the second application plate 32a. Bends in the thickness direction D3 of the brush 1, but is restricted from bending in the width direction D2 of the brush 1, and thus is prevented from spreading outside the width direction D2 of the brush 1. Therefore, according to the brush 1 of the first embodiment, as compared with the conventional brush 100 shown in FIG. 7, it is possible to suppress the liquid from being applied onto the application target corresponding to the outer side in the width direction D2 of the brush 1. As a result, it is possible to suppress the generation of uneven streaks (see FIG. 6B). The first coating plate 31a and the second coating plate 32a may be formed in a plate shape so that the bending of the brush 1 in the width direction D2 is limited, and the cross section is other than substantially rectangular. Other shapes may be used. Further, although the first application plate 31a and the second application plate 32a are formed in a plate shape over the entire length from the base end side to the tip end side in the first embodiment, a plurality of thinner than each end tip side. Bristles may be provided.

  The first application plate 31a and the second application plate 32a are made of a synthetic resin material such as silicone rubber, but magnetic powder is mixed in the first application plate 31a and the second application plate 32a. May be. Since magnetic powder is mixed in the first coating plate 31a and the second coating plate 32a, the coating plates 31a and 32a are damaged in a food processing factory, for example, so that the coating plates 31a and 32a may be damaged in food. Even if fragments are mixed in, the fragments can be reliably and easily collected by a metal detector or a magnetic catcher that attracts the fragments by using magnetic force.

  Each of the first application plate 31a and the second application plate 32a has a liquid holding portion 34 capable of holding a liquid on the plate surface, as shown in FIGS. 1, 2A and 2B. Is equipped with. The first coating plate 31a and the second coating plate 32a are provided with the liquid holding portion 34 on the plate surface, and thus have excellent liquid holding ability and, at the same time, the coating portion for applying the liquid onto the application target. When 3 was slid on the application target, the liquid holding portion 34 on the surface of the first application plate 31a or the second application plate 32a was slid on the application target and held by the liquid holding portion 34. The liquid can be effectively supplied onto the application target.

  In the first embodiment, the liquid holding portion 34 is formed as a hole portion 34a penetrating in the thickness direction of the coating plates 31a and 32a, as shown in FIGS. 2 (a) and 2 (b). The liquid is held inside the hole 34a by its surface tension. The shape of the hole 34a is not particularly limited, and a hole having a substantially circular shape, a substantially V shape, a substantially semicircular shape, or the like can be used, but it is substantially circular from the viewpoint of securing a liquid holding amount. It is preferable that it is opened. Further, the size and the number of the holes 34a can be appropriately set according to the viscosity of the liquid to be held and the required liquid holding amount. For example, by disposing the holes 34a in a distributed manner over the entire length from the base end side to the tip end side of the coating plates 31a and 32a, it is possible to increase the amount of liquid retained. Further, for example, by disposing the holes 34a dispersed only on a part of the base plates of the coating plates 31a and 32a, the holes 34a on the base ends of the coating plates 31a and 32a enter the inside of the coating unit 3. However, the liquid held inside the coating unit 3 is suppressed from coming out from the tip side of the coating plates 31a and 32a, which are not provided with the holes 34a, so that the liquid holding capacity of the coating unit 3 is reduced. Higher. Although the liquid holding portion 34 is formed as the hole portion 34a in the first embodiment, it may have another structure as long as it can hold the liquid, and is formed on the plate surfaces of the coating plates 31a and 32a. It may be a concave portion. The shape of the recess in that case is not particularly limited, and it is possible to employ a shape that is opened in a substantially circular shape, a substantially V shape, a substantially semicircular shape, etc. It is preferable that the openings are circular. Further, the size and the number of the recesses can also be appropriately set according to the viscosity of the liquid to be held and the required liquid holding amount. For example, the recesses may be distributed over the entire length from the base end side to the tip end side of the coating plates 31a, 32a, or may be distributed only on a part of the base end side or the tip side of the coating plates 31a, 32a. It can also be arranged.

  As shown in FIGS. 2A and 2B, the liquid holding portion 34 further includes a convex portion 34b provided on the peripheral edge of the hole portion 34a. By providing the convex portion 34b, the liquid holding portion 34 has a larger contact area with the liquid and can hold a larger amount of liquid. In the first embodiment, the protrusion 34b is provided on the entire periphery of the hole 34a, but is provided on at least a part of the direction in which the liquid flows down (the tip side direction of the coating plates 31a and 32a). May be. When the liquid holding portion 34 is formed as a concave portion instead of the hole portion 34a, the liquid holding portion 34 includes a convex portion provided on at least a part of the peripheral edge of the concave portion.

  Here, in the first embodiment, as shown in FIG. 2B, the convex portion 34b protrudes not only on the outer surface of the coating plates 31a and 32a in the thickness direction D3 but also on the inner surface thereof. . The convex portion 34b protruding on the inner surface functions to prevent the first coating plate 31a and the second coating plate 32a that face each other from sticking to each other in the thickness direction D3. That is, in the thickness direction D3 of the brush 1, the protrusions 34b provided on the surfaces of the coating plates 31a and 32a facing each other can secure the space S between the coating plates 31a and 32a without sticking to each other. Therefore, the liquid can be held between the first coating plate 31a and the second coating plate 32a. In particular, the convex portion 34b is provided on the peripheral edge of the hole portion 34a (or the concave portion) and functions to prevent the application plates 31a and 32a from sticking to each other around the liquid holding portion 34. It can be held more reliably. In order to prevent the application plates 31a and 32a from sticking to each other, at least one of the first application plate 31a and the second application plate 32a is replaced by the protrusion 34b of the liquid holding unit 34. In the thickness direction D3 of the brush 1 which is the direction in which the first application surface 31 and the second application surface 32 face each other, it is possible to prevent the first application plate 31a and the second application plate 32a that face each other from sticking to each other. It may have a protrusion.

  In the first embodiment, the liquid holding unit 34 is configured such that the first coating plate 31a and the second coating plate 32a extend in the direction in which the brush 1 extends, as shown in FIGS. 2 (a) and 2 (b). They are arranged side by side in a line at intervals I along the length direction D1. In the coating plates 31a and 32a, the liquid holding parts 34 are arranged side by side in a row, so that the liquid holding parts 34 are extruded from the liquid holding part 34 on the proximal end side toward the liquid holding part 34 on the distal end side. Liquid gradually moves. Therefore, the coating plates 31a and 32a can hold the liquid for a longer period of time without dropping the liquid onto the coating target at once.

  The method for forming the liquid holding portion 34 including the holes 34a and the convex portions 34b of the first embodiment on the coating plates 31a and 32a is not particularly limited, and is formed in an O-ring shape, for example. A method of embedding the resin molded product in the holes provided in the coating plates 31a and 32a may be adopted, or a method of integrally forming the liquid holding portion 34 when forming the coating plates 31a and 32a may be adopted. Good. The material of the liquid holding portion 34 is not particularly limited as long as it is a synthetic resin material such as silicone rubber, and the same synthetic resin material as the application plates 31a and 32a may be used, or the application plates 31a and 32a. You may use the synthetic resin material different from.

  Next, the operation and effect of the brush 1 of the first embodiment will be described with reference to FIGS. 5 and 6. In the following, an example of use of the brush 1 will be described in which a hamburger that is a food is the application target F and a source that is a liquid for food is a liquid L. However, the example of use described is merely an example, and the configuration of the brush 1 is described. The usage method of the brush 1 is not limited.

  The brush 1 gripped by the gripping means (not shown) is first immersed in the liquid L which is the source contained in the liquid container V, as shown in FIG. When the brush 1 is pulled out of the liquid L, as shown in FIG. 5B, in a state where the liquid L is held in the liquid holding portions 34 of the first application plate 31a and the second application plate 32a, It is moved to the coating object F which is a hamburger (see FIGS. 6A and 6B). At this time, since the liquid L is held by the liquid holding portion 34, the liquid L hardly drops from the coating plates 31a and 32a during the movement. Further, the convex portion 34b formed between the first coating plate 31a and the second coating plate 32a prevents the first coating plate 31a and the second coating plate 32a from sticking to each other even if they approach each other. Since the space S is secured between the first coating plate 31a and the second coating plate 32a, the liquid L is also held between the first coating plate 31a and the second coating plate 32a. Furthermore, since the application plates 31a and 32a are separated from each other, the liquid L can be applied to the application target F by each of the application plates 31a and 32a.

  Next, as shown in FIGS. 6A and 6B, the application portion 3 of the brush 1 that has been moved to the application target F is on the application target F along the thickness direction D3 of the brush 1. Can be slid. In the example shown in FIG. 6A, the surface of the second coating plate 32a is in sliding contact with the coating target F, and the liquid L held in the liquid holding portion 34 on the surface of the second coating plate 32a is It is supplied and applied on the application target F. Here, since the liquid holding unit 34 is provided on the surface of the second coating plate 32a that slides on the application target F, the liquid holding unit 34 also slides on the application target F and contacts the liquid holding unit 34. The retained liquid is effectively supplied onto the application target F. On the other hand, the liquid L held in the liquid holding portion 34 of the first coating plate 31a is extruded from the liquid holding portion 34 when the first coating plate 31a and the second coating plate 32a are in sliding contact with each other, It is supplied onto the application target F via the second application plate 32a. In addition, the liquid L held in the liquid holding portion 34 on the base end side of the first coating plate 31a and the second coating plate 32a that are not in sliding contact with the coating target F is the first coating plate 31a and the second coating plate. Since the liquid holding part 34 is also bent along with the bending of the coating plate 32a, the liquid L is ejected from the curved liquid holding part 34. The liquid L extruded from the liquid holding section 34 on the base end side sequentially moves to the adjacent liquid holding sections 34, and moves toward the tip side of the coating plates 31a, 32a along the surfaces of the coating plates 31a, 32a. Move gradually. Therefore, the liquid L does not fall from the coating plates 31a and 32a at one time, and is held on the coating plates 31a and 32a for a long time. At this time, since the first coating plate 31a and the second coating plate 32a are formed in a plate shape so that the bending of the brush 1 in the width direction D2 is limited, the width direction of the brush 1 is reduced. The liquid L is uniformly applied onto the application target F without spreading to the outside of D2 (see FIG. 6B).

  In the above-described brush 1 of the first embodiment, the liquid holding portions 34 provided on the first coating plate 31a and the second coating plate 32a respectively have the first liquid holding portion 34, as shown in FIG. The coating plate 31a and the second coating plate 32a are arranged at positions corresponding to each other in the length direction D1 of the brush 1 which is the extending direction. However, as in the second embodiment shown in FIG. 3, the liquid holding portion 34 provided on each of the first coating plate 31a and the second coating plate 32a has the same structure as the first coating plate 31a and the second coating plate 31a. In the length direction D1 of the brush 1, which is the direction in which the coating plate 32a of FIG. By arranging the liquid holding parts 34 of the coating plates 31a and 32a so as to be offset from each other, the liquid holding parts 34 are arranged more dispersedly over the entire coating part 3, and the coating part 3 is The liquid can be held more uniformly as a whole. Therefore, the brush 1 can apply the liquid more evenly on the application target.

  Further, in the brush 1 of the first embodiment described above, the first coating plate 31a and the second coating plate 32a are, as shown in FIGS. 1 and 2A, in the width direction D2 of the brush 1, They are arranged so as to face each other at positions corresponding to each other. However, as in the third embodiment shown in FIG. 4, the first coating plate 31a and the second coating plate 32a are in the directions in which the first coating plate 31a and the second coating plate 32a extend, respectively. In the length direction D1 of the brush 1 and the width direction D2 of the brush 1 which is a direction perpendicular to the thickness direction D3 of the brush 1 which is the direction in which the first application surface 31 and the second application surface 32 face each other, They may be arranged offset from each other. By disposing the first coating plate 31a and the second coating plate 32a offset from each other in the width direction D2 of the brush 1, the gap G between the first coating plate 31a and the second coating plate 32a is reduced. Since the brushes 1 are arranged so as to be offset from each other in the width direction D2, the liquid can be more uniformly applied onto the application target.

  Moreover, the application part 3 of the brush 1 of the first embodiment described above includes two application surfaces, a first application surface 31 and a second application surface 32. However, another coating surface or another coating portion may be provided between the first coating surface 31 and the second coating surface 32 or outside the thickness direction D3. When three or more coating surfaces are provided in the coating section, the coating surfaces may have the same structure or different structures. For example, when the coating section is provided with three coating surfaces, the middle coating surface may be formed as one coating plate, and the coating surfaces on both sides may be formed by a plurality of coating plates. In that case, since the middle coating surface can hold more liquid, the ability of the entire coating unit to hold liquid is further increased. Alternatively, the application plate on the middle application surface is provided with holes, which are liquid holding parts, dispersed throughout, and the application plates on both sides are provided with holes, which are liquid holding parts, on the proximal side. It may be dispersed and arranged only in a part of. In that case, the liquid that has penetrated from the holes on the base end side of the coating surface on both sides toward the middle coating surface and is retained inside the coating portion has no holes, and the tips of the coating surfaces on both sides. Since it is possible to prevent the liquid from coming out from the side to the outside, the liquid holding capacity of the application section is further enhanced.
