Description

  The present invention relates to a container holder that holds a container in a sterilization tank that is heated in steam and vacuum-dried in order to sterilize a container that contains food.

  Conventionally, containers for food are manufactured by various molding methods, and are sterilized by various methods after molding from the viewpoint of food hygiene.

  One of them is a method of sterilizing a container by steam heating. In this method, as shown in FIG. 9, the molded container C is held in a container holder 50, accommodated in a sterilization tank, and the sterilization tank is filled with steam to be in a high temperature and high pressure state so that the container is sterilized. Is applied, and the inside of the sterilization tank is evacuated (evacuated) to evaporate the water adhering to the container.

  The container holder 50 includes a support 51 that supports the container C (a plurality of containers C in FIG. 9). The support body 51 is configured such that steam is brought into contact with substantially the entire surface of the container C in a state where the container C is disposed, so that the container C can be surely sterilized. Although there are various types of supports 51, the support 51 shown in FIG. 9 is composed of a pair of rods 51a and 51b arranged in parallel at a predetermined interval. When the container C is disposed in a lying state, the container C is supported in a point contact state by the pair of rods 51a and 51b.

  Further, the container holder 50 is configured so that a large number of containers C can be sterilized at a time so that the container holders 50 having the same configuration can be accommodated in the sterilization tank. Therefore, when the plurality of container holders 50 are stacked, the support 51 and the container C are sequentially overlapped.

  By the way, when the sterilization tank is filled with steam, the steam attached to the ceiling surface of the sterilization tank, the stacked container holder 50 (support 51), or the like may condense and become water (condensed water). Then, since the container C is only arranged on the support 51 of the container holder 50 in the sterilization tank, the condensed water will fall onto the container C, and the sterilization tank is evacuated. However, there is a problem that water (condensed water) adhering to the container C cannot be efficiently dried in a short time.

  Further, when the condensed water cannot be completely evaporated in this way, the condensed water is taken out from the sterilization tank while the condensed water is attached to the container C. If the condensed water adheres to the container C as described above, there is also a problem that various germs are likely to adhere, and the sterilization process becomes difficult.

  Therefore, in view of such circumstances, the present invention can reliably sterilize the container without the condensed water adhering to the container even if the steam falls into the condensed water in the sterilization tank. It is an object to provide a container holder.

A container holder according to the present invention is a container holder that is provided in a sterilization tank that includes a support that supports a container that contains food, and that is heated in a vacuum and vacuum-dried to sterilize the container on the support. And a cover that covers at least a portion facing upward of the container disposed on the support in a non-contact state, and the cover is opposed to a portion facing upward of the container on the support in a non-contact state. And a first cover member provided at one end of the upper cover portion and provided with a side cover portion facing in a non-contact state to one portion facing the side of the container, and on the side of the container The second cover member is disposed in a non-contact state and opposed to the other part opposite to the one part facing, and the upper cover part has a surface facing the container formed at least at the one end side. The second cover member has an upper end The first cover member that is located on one end side with respect to the other end of the upper cover portion and that has a predetermined interval with respect to one surface of the upper cover portion that faces the container, The surface constitutes a guide surface that guides the attached condensed water to the outside of the region where the container is disposed, and one surface of the second cover member that faces the container guides the attached condensed water downward. It is characterized by constituting a surface. Here, the portion facing the upper side of the container does not mean a portion facing the upper side of the container in a normal mode, but means a portion facing the upper side in a state of being arranged on the support. is there. Further, the portion facing the side of the container means not the portion facing the side of the container in a normal mode, but the portion facing the side in a state of being arranged on the support, for example, When the bottomed cylindrical container is supported by the support in a lying state, the part facing upward of the container becomes a peripheral wall, and the part facing the side of the container becomes any of the peripheral wall, the bottom, and the opening end face.

  According to the container holder configured as described above, the following effects can be obtained. That is, when the container is placed on the support and the container holder is housed in the sterilization tank, the sterilization tank is filled with the steam, and the sterilization tank is filled with the steam, and between the cover and the container. Steam enters the state. And even if the vapor | steam adhering to the ceiling surface etc. of a sterilization tank condenses, it liquefies and falls, this liquefied vapor | steam (condensed water) is received by the cover, and it prevents that it adheres to the container on a support body. Is done.

And the vapor | steam adhering to a container and a cover will also condense and liquefy, However, When one surface (partial area | region of a guidance surface) of an upper cover part is formed in the one end side, it falls first. The condensed water adhering to the surface is guided toward the side cover portion due to the downward movement of the surface, and is then directed downward along one surface of the side cover portion. become.

On the other hand, when one surface of the upper cover part (partial region of the guide surface) is formed so as to be lowered toward the other end, the condensed water adhering to the surface is lowered to the tip of the surface. As a result, after being guided to the other end, it falls from the other end of the upper cover part, but the presence of the second cover member prevents the condensed water from adhering to the container. Moreover, the condensed water adhering to one surface (partial region of the guide surface) of the second cover member is guided (dripped or flows) toward the lower side along the surface.

  And even if the induced condensed water falls, the condensed water will fall in the area | region where a container does not already exist, Therefore This condensed water is prevented from adhering on a container. Therefore, since the container is in a state where a small amount of condensed water obtained by liquefying the vapor attached to the container is attached, the condensed water attached to the container can be completely dried by vacuum drying the sterilization tank. The container can be taken out from the sterilization tank in a manner preferable for food hygiene.

Further, in the container holder having the above-described structure , a gap is formed between the first cover member and the second cover member, so that steam is heated between the cover and the container via the gap between the cover members during steam heating. Can flow efficiently in a short time, and the container can be sterilized by heating in a short time .

  On the other hand, when vacuum-drying, moisture intervening between the cover and the container is discharged through the gaps between the cover members, and the container can be efficiently dried.

  In this case, it is preferable that one surface of the upper cover portion is formed of a bent surface and is inclined so as to be lowered toward both ends. If it does in this way, the condensed water adhering to an upper cover part flows toward the both ends of an upper cover part, and can guide condensed water toward the boundary of a guide surface efficiently. In other words, when the container supported by the support is large, one surface of the upper cover portion has a large area, and thus the condensed water is divided in two directions to induce condensed water in one direction. Is more efficient than inducing.

The first cover member and the second cover member are preferably made of a plate material. In this way, since the other surfaces of the first cover member and the second cover member have a shape corresponding to one surface constituting the guide surface, the condensed water that has fallen on the cover is more than the tip of the other surface. It can be induced in the downward direction due to the lowering, and can prevent the condensed water from accumulating on the cover.

  In this case, it is preferable that the said board | plate material is comprised with the pickled stainless steel plate. When the stainless steel plate is pickled in this way, the surface becomes rough, so that the hydrophilicity with respect to the attached condensed water is increased, and it is possible to reliably prevent the condensed water from falling before being guided by the guide surface.

  As described above, according to the container holder according to the present invention, even if the steam falls as condensed water in the sterilization tank, the condensed water does not adhere to the container, and the container is reliably sterilized. It is possible to achieve an excellent effect of being able to.

  As shown in FIG. 4, the cover 3 is configured to cover at least a portion facing the upper side of the container C disposed on the support 1 in a non-contact state, and a surface 30 facing the container C is provided. The condensate adhering to the surface 30 is configured to be guided to an area outside the arrangement area of the container C (area occupied by the container C in plan view) (area where the container C does not exist below) ( Hereinafter, this surface 30 is referred to as a guide surface). That is, the guide surface 30 is formed so as to descend toward the boundary (the outer edge of the guide surface 30) that defines the guide surface 30, and the condensed water adhering to the guide surface 30 due to this tip-down. Can be guided toward the boundary located in the area where the container C does not exist. In addition, although the guide surface 30 should just incline at 5 degrees or more with respect to the horizontal virtual line La, More preferably, it is preferable to incline at 10 degrees or more with respect to the temporary clothing line La.

  The cover 3 according to the present embodiment is configured by a plurality of cover members (in the present embodiment, two cover members 31 and 32) that cover the container C on the support 1, and the guide surface 30 has each guide surface 30. The cover members 31 and 32 are intermittently formed by one surface facing the container C. Therefore, in the cover 3 according to the present embodiment, a set of intermittently arranged surfaces (one surface on each of the cover members 31 and 32) forms a guide surface 30 that faces the container C.

  Specifically, the cover 3 according to the present embodiment is opposed to a portion facing the upper side of the container C on the support 1 (a portion facing the upper side of the peripheral wall of the container C in the present embodiment) in a non-contact state. The upper cover part 310 and one end of the upper cover part 310 that are suspended from one end and face the side of the container C (in this embodiment, one part that faces the side of the peripheral wall of the container C). A first cover member 31 which is a cover member provided with side cover portions 311 facing each other in a non-contact state, and a portion on the other side facing the side of the container C (in this embodiment, on the side of the peripheral wall of the container C) And a second cover member 32 which is a cover member disposed in a non-contact manner in a non-contact state.

  Each of the first cover member 31 and the second cover member 32 is formed by bending a substantially rectangular plate material. In the present embodiment, a pickled stainless steel plate is used. ing.

  The first cover member 31 has a ridge line L1 (hereinafter referred to as a first ridge line L1) formed by mountain-folding the plate material on the other surface side with a reference line substantially parallel to the axis of the rods 1a and 1b. ), The upper cover portion 310 and the side cover portion 311 are formed.

  The upper cover portion 310 is formed by further folding a plate material on the other surface side with a reference line substantially parallel to the first ridge line L1, and bordering a ridge line L2 (hereinafter referred to as a second ridge line) formed by the mountain fold. In addition, a first upper cover portion 310a is formed on one end side where the side cover portion 311 is connected, and a second upper cover portion 310b is formed on the other end side. Accordingly, one surface of the first upper cover portion 310a facing the container C is inclined downward toward the one end side (boundary of the guide surface 30), and one of the second upper cover portions 310b facing the container C is one side. Is inclined downward toward the other end side (boundary of the guide surface 30). As a result, the surface of the upper cover portion 310 facing the container C forms a bent surface that descends from the region closer to the center toward both ends. In the present embodiment, the length of the first upper cover portion 310a in the direction orthogonal to the ridgelines L1 and L2 is set to be shorter than the length of the second upper cover portion 310b.

  One end portion of the second upper cover portion 310b, which is the other end portion of the upper cover portion 310, is further folded into a plate material on the other surface side along a reference line substantially parallel to the second ridgeline L2, and a hanging piece portion 310c. Is formed.

  The side cover portion 311 is further folded into a mountain on the other surface side with a reference line substantially parallel to the first ridge line L1, and bordered by a ridge line L3 (third ridge line) formed by the mountain fold. The upper side cover portion 311a is formed on the upper side (the connection side with the upper cover portion 310), and the lower side cover portion 311b is formed on the lower side.

  The first cover member 31 having the above-described configuration has respective bending angles set so that the hanging piece portion 310c and the upper side cover portion 311a are substantially parallel. In the present embodiment, the first upper cover portion The inclination of the second upper cover part 310b is more than the inclination angle θ1 of the first upper cover part 310a with respect to the horizontal virtual line La passing perpendicularly to the boundary (first ridge line L1) between the 310a and the second upper cover part 310b. The angle θ2 is set to be smaller, and both the first upper cover portion 310a and the second upper cover portion 310b are inclined downward from the center toward the edge. In other words, each of the first upper cover part 310a and the second upper cover part 310b is closer to the outer side than the occupied area in a plan view of the container C arranged on the support 1, and is more end than the center side. It is formed so that the edge side is located below.

  Further, the lower side cover portion 311b of the side cover portion 311 is inclined so that the lower end is positioned slightly closer to the container C side than the upper end in a state where the upper side cover portion 311a is in a substantially vertical state. In the first cover member 31 configured in this manner, the hanging piece portion 310c and the upper side cover portion 311a are substantially vertical, and the ridgelines L1, L2, L3 and the shaft centers of the rod bodies 1a, 1b are substantially the same. The first plate 20 and the first plate 20 so that the upper cover 310 and the side cover 311 are not in contact with the container C in a state in which the container C is arranged on the support 1 in parallel. It arrange | positions between the 2nd plates 21, and the both ends of the length direction of ridgeline L1, L2, L3 are connected with this 1st plate 20 and the 2nd plate 21. As shown in FIG. The minimum gap between the upper cover part 310 and the side cover part 311 and the container C is preferably about 1 mm to 1.5 mm.

  Accordingly, the first cover member 31 includes an upper cover portion 310 (first upper cover portion 310a, second upper cover portion 310b, hanging piece portion 310c) facing the container C, and a side cover portion 311 (upper side portion). One surface of the cover portion 311a and the lower side cover portion 311b) constitutes a guide surface 30a for guiding the attached condensed water to the outside of the region where the container C is disposed.

  The second cover member 32 folds the plate material on the other surface side with two reference lines substantially parallel to the axis of the rods 1a and 1b, and a ridge line L4 (hereinafter referred to as a first ridge line L4) formed by the mountain fold. A first region 32a is formed on one end side, and a second region 32b is formed on the other end side. Further, the first region 32a is valley-folded on the other surface side of the plate member by a reference line substantially parallel to the fourth ridge line L4, and the first region 32a is located on one end side of the plate member with the fold line L5 as a boundary. A region 322a is formed, and a middle region 322b is formed on the other end side.

  The second cover member 32 having the above-described configuration is provided in an upright state with an upper end positioned on one end side with respect to the other end of the upper cover portion 310 and spaced from one surface of the upper cover portion 310. Yes. Specifically, the second cover member 32 has one surface facing the side where the container C is disposed, and the upper region 322a is spaced from the second upper cover portion 310b and the hanging piece portion 310c, and In a state where the second region 32b is substantially vertical, the first plate 20 and the second plate 21 are arranged between the first plate 20 and the second plate 21, and both ends of the fourth ridge line L4 in the length direction are the first plate 20 and the second plate. 21 is connected. Similarly to the first cover member 31, the second cover member 32 is provided so that one surface thereof is not in contact with the container C, and the vapor between the one surface and the container C is condensed. Thus, the guiding surface 30b for guiding the condensed water adhering thereto downward is configured.

  Therefore, the cover 3 having the above-described structure covers the container C at the upper part and the side part by the first cover member 31 and the second cover member 32, and faces the container C side (respective guide surfaces 30a and 30b). ), The guide surface 30 of the cover 3 is formed intermittently.

  The container holder H concerning this embodiment consists of the above structures, and demonstrates the effect | action of this container holder H next.

  First, the shutter plate 22 is slid, and a plurality of containers C stacked from the loading port 210 of the second plate 21 are loaded in a lying state. Then, the plurality of containers C sequentially enter between the first plate 20 and the second plate 21 through the loading port 210. At this time, the plurality of containers C that have passed through the loading port 210 are slid on the pair of rods 1a and 1b (support 1).

  All of the stacked containers C reach between the first plate 20 and the second plate 21. When the shutter plate 22 is closed in this state, the superposed container C is held between the first plate 20 and the shutter plate 22. The shutter plate 22 is positioned in contact with the stopper 212 in a state where the center of the hole between the second through hole 214 and the loading port 210 of the second plate 21 is substantially coincident.

  And also with respect to the plurality of container holders H, H..., The plurality of containers C are accommodated by the above process, and the container holders H, H. ).

  Thereafter, when the sterilization tank P is filled with steam, the opened part of the container holder H (between the first cover member 31 and the second cover member 32, the first through hole 200, the second through hole 214, the cover). The steam flows into the space between the container C on the support 1 and the cover 2 from the lower part of the container holder H 3 and the like. And the germs adhering to the container C will be killed by leaving it in this state for a predetermined time.

  When the steam is filled in the sterilization tank P in this way, the steam attached to the ceiling surface of the sterilization tank P becomes condensed water and falls onto the uppermost container holder H. Since the cover 3 is provided, the presence of the cover 3 prevents the condensed water from adhering to the container C. In addition, since the cover 3 concerning this embodiment is comprised with the board | plate material, the other surface has comprised the aspect corresponding to one surface which comprises the induction | guidance | derivation surface 30, and the condensed water which fell on the cover 3 is The cover 3 (the first upper cover portion 310a and the second upper cover portion 310b) flows toward both ends of the upper cover portion 310 due to the inclination (first downward). Then, the condensed water flowing on the other surface of the first upper cover portion 310a falls to a region outside the occupied region of the container C in plan view, which covers the other surface of the side cover portion 311. On the other hand, the condensed water flowing on the other surface of the second upper cover portion 310b falls along the other surface of the drooping piece portion 310c. The condensed water falling from the drooping piece 310c does not adhere to the container C due to the presence of the second cover member 32, and falls to an area outside the occupied area of the container C in plan view.

  Further, the steam interposed between the cover 3 and the container C adheres to the first cover member 31, the guide surface 30 of the second cover member 32, and the outer peripheral surface of the container C to become condensed water. Then, the condensed water adhering to the container C flows downward along the outer peripheral shape of the container C, and falls toward the lower container holder H via the support 1 (the pair of rods 1a and 1b). However, since the cover 3 is provided in each container holder H, the condensed water for the container C is also present in the presence of the cover 3 in the same manner as the condensed water falling from the ceiling surface of the sterilization tank P. Adhesion is prevented.

  Although the vapor | steam adhering to the guidance surface 30 facing the container C in the cover 3 will also condense and liquefy, the upper cover part 310 has the 1st upper cover part 310a facing the container C, and 2nd upper direction. Since one surface of the cover part 310b is an inclined surface that descends toward the edge side, the condensed water adhering to one surface of the cover 3 is intermittently formed by the inclination of the guide surface 30. In addition, the air flows toward the boundary (outside) defining the guide surface 30. Specifically, the condensed water in which the steam is condensed adheres to the entire surface of the guide surface 30 of the cover 3 (the entire surfaces of the guide surfaces 30a and 30b of the first upper cover portion 310a and the second upper cover portion 310b). Therefore, a large surface tension acts on the condensed water. Thus, the condensate flows along the surface of the guide surface 30 without falling, because the guide surface 30 is formed in a tip-down manner.

  The condensed water that flows toward the edge of the first upper cover part 310a (one end of the upper cover part 310) falls from the lower end of the side cover part 311 that connects to the guide surface 30 of the side cover part 311. Will do. On the other hand, the condensed water that flows toward the edge of the second upper cover portion 310b (the other end of the upper cover portion 310) passes from the lower end of the hanging piece portion 310c via the guide surface 30 (30a) of the hanging piece portion 310c. Although it falls, it falls without adhering to the container C due to the presence of the second cover member 32.

  Thus, even if condensed water falls from the lower end of the side cover part 311 and the drooping piece part 310c, since the cover 3 is also provided in each container holder H located below, the condensed water is contained in the container C. Adhering to the surface is surely prevented.

  Then, when the inside of the sterilization tank P is vacuum degassed, the water adhering to the container C and the cover 3 are attached from between the first cover member 31 and the second cover member 32 or from the opened lower portion of the container holder H. Water and the like are discharged, and the container holder H and the container C are completely dried.

  As mentioned above, since the condensed water which falls does not adhere to the container C, the container C can be reliably dried in a short time, and it is taken out from the sterilization tank P with the excess water adhered. Can be prevented. Therefore, if the container holder H concerning this embodiment is employ | adopted, a preferable sterilization process can be performed on food hygiene.

  In addition, since the guide surface 30 according to the present embodiment is configured by an inclined surface, the condensed water can be reliably and stably guided to an area where the container C does not exist.

  In addition, since the container holder H having the above-described configuration is formed by bending the plate material of the cover 3, the condensed water can be guided toward the boundary of the guide surface 30 on both surfaces of the cover 3.

  In the container holder H of the present embodiment, the cover 3 is composed of the first cover member 31 and the second cover member 32, and a gap is formed between the first cover member 31 and the second cover member 32. Even if the cover 3 is provided on the container holder H, the steam can be efficiently poured between the cover 3 and the container C, and moisture existing between the cover 3 and the container C during vacuum drying can be removed. It can be discharged efficiently.

  In addition, since the cover 3 of the container holder H according to the present embodiment is made of a pickled stainless steel plate, the surface of the guide surface 30 for guiding condensed water is rough, and the surface tension of the attached condensed water is maximized. It is possible to prevent the ink from being drawn out and dripped.

Next, a container holder according to a reference example will be described. Incidentally, container holder according to this reference example, only different in structure of the container holder and the cover of the above embodiment, which is configured in the same for the other configuration, the same components as the above embodiment The same name and the same reference numerals are attached and the description is omitted.

As shown in FIG. 5, the cover according to this reference example is directed to the upper cover body 60 that is disposed with one surface facing the upper portion of the container C in a non-contact state and to the side of the container C. It is comprised with a pair of side cover member 61 arrange | positioned with one surface facing a part in a non-contact state.

  The upper cover body 60 is provided on a lower side of both end portions of the first upper cover member 600, and a first upper cover member 600 in which a plate material is mountain-folded on the other surface side so as to be lowered toward both ends. And a pair of second upper cover members 601 made of a plate material. Each side cover member 61 is formed in an L shape by bending one end of a plate material.

  The first upper cover member 600 is provided so that one surface (bent surface) faces the portion facing upward of the container C. The second upper cover member 601 is opposed to one surface at both ends of the first upper cover member 600 with the other surface of one end thereof having a predetermined interval, and descends toward the other end side. It is provided with an inclination.

  The side cover body 61 is placed on the support body 1 in a state where the other surface of the bent one end portion is opposed to one surface of the other end portion of the second upper cover member 601 with a predetermined interval. It is provided so that it may oppose in the non-contact state to the part facing the side of the container.

  Accordingly, one surface of the first upper cover member 600, the second upper cover member 601, and the side cover member 61 facing the container C on the support 1 is pointed toward the lower end of each side cover member 61. The guide surface 30 inclined downward is formed intermittently.

  When the cover 6 is configured in this way, the condensed water adhering to one surface (the guide surface 30) of the first upper cover member 600 is caused by the inclination of the guide surface 30 and the edge of the first upper cover member 600 After being guided toward the side, it flows (induces) toward the lower end of the side cover member 61 along the other surface of the second upper cover member 601 and the side cover member 61. Further, the condensed water adhering to one surface (guidance surface 30) of the second upper cover member 601 is guided toward the edge of the first upper cover member 600 due to the inclination of the guidance surface 30. The condensed water adhering to one surface of the side cover 61 flows along (induces) the other surface of the side cover member 61 toward the lower end of the side cover member 61. Due to the posture of the side cover 61, the side cover 61 is guided toward the lower end. Therefore, even if condensed water adheres to one surface of the cover 6 facing the container C, the condensed water is completely prevented from falling onto the container C. In addition, since a predetermined gap is formed between each of the first upper cover member 600, the second upper cover member 601, and the side cover member 61, the inflow of steam and moisture can be passed through the gap. The discharge can be performed smoothly.
