Description

Sealing device

This invention relates to a sealing device and a sealing method for sealing a container by sealing a lid on the container.

In the prior art, in convenience stores, supermarkets, fast food restaurants and other stores, beverages such as coffee, carbonated drinks, and side dishes are generally provided in containers (hereinafter, the above-mentioned various beverages are sometimes referred to as "contents"). In addition, in the prior art, containers with contents pre-stored in them are displayed in the store for provision, or store staff provide the contents in containers on the spot according to the purchaser's order. In recent years, in addition to the above-mentioned provision methods, a provision method is also being implemented in which the purchaser stores the contents in the container and takes it home.

Generally, when providing contents in a state of being stored in a container, a lid is often placed on the container storing the contents. There are also various forms of placing a lid on a container, and as one of the forms, a heat sealing method of joining a lid body to a container by heating, or an ultrasonic welding method of joining a container and a lid by applying ultrasonic waves is known. According to these methods, the lid body is joined to the edge portion formed around the opening of the container, so that the container is sealed inside. As described above, in order to achieve a state in which the lid body is joined to the edge portion of the container and the inside of the container is sealed, a sealing device for joining the lid body to the container to seal is generally used. As a previously known sealing device, for example, the one described in Patent Document 1 shown below can be cited. The sealing device (closing device) described in the patent document 1 is used to heat-seal the edge of the container with a film member serving as a lid and join the lid to the container to seal the container. The closing device includes: a device body, a support portion for supporting the container, and a hot press plate for heat-sealing the film member on the container supported by the support portion. The support portion is configured to be able to slide between a position pulled out further forward than the entire surface of the device body (a position further outward than the device body) and a position below the hot press plate in the device body. The support portion is located at a position further outward than the device body when supporting the container, and slides to a position below the hot press plate when closing the lid on the supported container. Furthermore, if the lid is sealed on the container by the hot press plate at this position, the support part slides from the position below the hot press plate to a position further outside the device body. The purchaser who buys drinks etc. can take the container out of the support part located further outside the device body and take it back.

[Patent Document 1] Japan Utility Model Registration No. 3152023

The sealing device disclosed in the above-mentioned patent document 1 is constructed as follows: a long strip of film wound in a roll is arranged on a roller (active roller) on one side, and the front end of the film wound in a roll is installed on a roller (passive roller) on the other side. By rotating the passive roller, the film arranged on the active roller is sequentially pulled out and wound on the passive roller. The part of the film sealing on the container is located between the active roller and the passive roller, and is constructed as follows: through this part, the film of the long strip is cut into a shape corresponding to the size and shape of the container and the container is heat-sealed.

However, in the case of a sealing device that seals the container by cutting the long strip of film into a predetermined size and shape and heat-sealing the container as described above, the long strip of film wound on the passive roller is hollowed into a predetermined shape. The long strip of film wound on the passive roller can only be discarded in the end, and there is a problem that the film loss after the lid is removed is very large. In addition, in the case of the sealing device disclosed in Patent Document 1, the film is cut from the long strip of film when heat-sealing the container, and there is also a concern that dust generated when the film is cut will mix into the container.

Furthermore, the sealing device described in Patent Document 1 requires a film cutting mechanism in addition to a heat-sealing film mechanism on the container. Therefore, not only is the structure of the sealing device likely to become complicated, but there is also the concern that, for example, when a store clerk is inspecting or cleaning the interior of the sealing device, the film cutting mechanism may be accidentally touched and damaged.

[First implementation method]

First, the first embodiment of the sealing device of the present invention is described. The sealing device 1001 of the present invention is used to seal the opening of a container having an opening and an edge forming the outer periphery of the opening with a single-piece cover. The appearance structure of the sealing device 1001 of the first embodiment is shown in Figures 1 and 2. Figure 1 is a three-dimensional view of the appearance of the sealing device 1001 of the present embodiment, and Figure 2 is a three-dimensional view of the appearance of the sealing device 1001 of the present embodiment, which is a state in which the storage part 1006 described later is removed.

As shown in FIG. 1 and the like, the sealing device 1001 of the present embodiment is a form in which a person (hereinafter referred to as a "user") who seals a lid on a container manually performs sealing. The sealing device 1001 includes a housing 1002, a holding portion 1003, a sealing portion 1004, an operating portion 1005, and a storage portion 1006. The housing 1002 is a member that serves as a base of the sealing device 1001. The housing 1002 is formed by forming a metal plate of a previously known material such as iron or stainless steel. In the sealing device of the present embodiment, the bottom plate 1007, the right side plate 1008, the left side plate 1009, the rear plate 1010, etc. of the housing 1002 are formed by previously known methods such as welding or bending, but the method of forming the housing 1002 is not limited to the above, and the housing 1002 can also be made by other methods. The bottom plate 1007 is a plate-shaped component located at the lower part of the sealing device 1001, and has through holes formed at four locations of the front, rear, left and right. The four through holes can be installed with rubber feet, etc. The right side plate 1008, the left side plate 1009, and the rear plate 1010 are formed in a manner of standing from the bottom plate 1007. Furthermore, the right side plate 1008 and the rear plate 1010, and the left side plate 1009 and the rear plate 1010 are integrated with each other by bonding or the like. Thus, a storage space 1011 is formed in the housing 1002. The storage space 1011 is a space for arranging or installing various parts or components constituting the sealing device 1001. Furthermore, on the right side plate 1008 and the left side plate 1009, at the upper end, the end is formed at a predetermined position by bending and forming in a manner that the end faces inward. In addition, on the rear plate 1010, an opening hole is formed for fixing the socket to the sealing device 1001.

The holding portion 1003 is used to hold the container in a state where the edge of the container is exposed, and is disposed in the storage space 1011 in the housing 1002. The holding portion 1003 includes a holding base portion 1012 and a holding member 1 (hereinafter also referred to as "holding member 1"). The holding base portion 1012 is a member that serves as a base for mounting and fixing the holding member 1. The holding base portion 1012 includes a holding member fixing portion for mounting and fixing the holding member 1, and a holding base fixing portion for mounting and fixing the holding member 1 on the right side plate 1008 and the left side plate 1009 by screwing or other methods. The holding base portion is preferably installed on the right side plate 1008 and the left side plate 1009 in a manner that the holding member 1 is horizontally arranged when the holding member 1 is installed, and the holding base fixing portion is preferably processed in a manner that the outer surface of the holding base fixing portion is along the inner surface of the right side plate. The holding base fixing portion can be formed by bending the two ends of the forming member used to form the holding base portion, or the member used to form the holding base fixing portion and the member used to form the holding member installation portion can be formed in different bodies, and the members can be joined by welding or other methods. In addition, the holding base portion can also be formed by methods other than the above. In addition, the structure of the holding member 1 constituting the holding portion 1003 is as described below.

The sealing part 1004 is used to seal the lid at the periphery of the container and seal the container. As shown in FIG. 1, the sealing part 1004 includes a heater 1013 as a joint body for joining the lid at the edge formed at the periphery of the opening, and a cover member 1014. The heater 1013 includes a heater body 1015, a substrate 1016, and a spring member (not shown) provided between the heater body 1015 and the substrate 1016 as an extrusion pressure imparting member. The heater body 1015 is formed in a disk shape in this embodiment, but the shape and size of the heater body 1015 can also be arbitrarily changed according to the shape and size of the sealed object, that is, the container and the lid. In addition, the wire extending from the heater body 1015 is used to supply power to the heater body 1015. The substrate 1016 is located above the heater body 1015 and is used to increase the compressive force caused by the heater body 1015 by compressing and deforming the spring member during extrusion. The spring member is used to increase the compressive force applied to the edge of the cover and the container when the heater body 1015 is used to compress the cover and the container. The compressive force of the spring member can be adjusted by adjusting the length of the spring member during normal times other than extrusion to adjust the force of the heater body 1015.

The cover member 1014 is a cover-shaped member formed in a manner to cover the periphery of the heater 1013 (at least the front of the heater 1013). The cover member can block the heat radiated from the heater body 1015, and can also prevent the user from touching the heater 1013 (heater body 1015) when holding the container in the holding portion 1003. In addition, the cover member 1014 can be made of any previously known raw materials, but since it is arranged near the heater 1013, it is preferably made of a material that is not easily affected by the heat radiated from the heater 1013.

The moving part is used to move the sealing part 1004 between the first position and the second position. The moving part includes: a guide rail 1017 installed on the right side plate 1008 and the left side plate 1009, and a moving body 1018 moving along the guide rail 1017. The moving body 1018 is connected to the sealing part 1004 and the operating part 1005 described later. If the moving body 1018 moves along the guide rail 1017, the sealing part 1004 and the operating part 1005 can move between the first position and the second position as a whole.

The operating part 1005 has a gear 1019, a gear 1020 and a rod 1021. One end of the gear 1020 is connected to the base plate 1016 of the heater 1013, and is configured to be able to slide in the vertical direction. In addition, the gear 1019 is configured to mesh with the gear of the gear 1020, and the gear 1020 can move in the Z-axis direction (vertical direction) as the gear 1019 rotates. The rod 1021 is connected to the gear 1019 via the shaft member 1022, and is configured as follows: if the user operates the rod 1021, the gear 1019 rotates, and as the gear 1019 rotates, the gear 1020 and the heater 1013 connected to the gear 1020 move in the Z direction.

A lock receiving portion 1023 is mounted on the upper end of the left side plate 1009 in the housing 1002. A lock portion 1024 is formed on the operating portion 1005. The lock portion 1024 and the lock receiving portion 1023 are in a positional relationship in which the lock portion 1024 enters the lock receiving portion 1023. The lock portion 1024 is disposed at a position displaced by the rotation of the gear 1019 accompanying the rotation operation of the rod 1021. That is, when the gear 1019 rotates, the locking portion 1024 is disposed at a position radially outward from the rotation axis, and is configured such that when the gear 1019 rotates, the locking portion 1024 moves in an arc and in an up-and-down direction as the gear 1019 rotates. Specifically, the locking portion 1024 is disposed at a position such that when the rotation operation is performed in the direction of lowering the rod 1021 (i.e., the action of lowering the heater 1013), the locking portion 1024 moves in an upward direction, and conversely, when the rotation operation is performed in the direction of raising the rod 1021 (i.e., the action of raising the heater 1013), the locking portion 1024 moves in a downward direction. The lock receiving part 1023 has a top surface 1025 as a stop surface, and is configured as follows: if the lock part 1024 abuts against the top surface 1025, the rotation operation in the direction of the lowering rod 1021 can be restricted. In addition, the lock release part 1026 is provided on the front end side of the lock receiving part 1023. The lock release part 1026 does not have a part abutting against the lock part 1024, and is configured as follows: the rotation operation in the direction of the lowering rod 1021, that is, the restriction on the movement in the direction of the heater 1013 descending is released.

Next, the structure of the retaining member 1 constituting the retaining portion 1003 and its various variations are described.

For example, in one embodiment, the retaining member 10 includes a retaining body 11. The retaining member 10 is formed into a rectangular shape when viewed from above, but this is an example and does not prohibit it from being in other shapes. The outer peripheral shape of the retaining member 10 when viewed from above, in addition to a rectangular shape, can also be any of a circular shape, a tongue shape, an elliptical shape, a polygonal shape, etc. For example, the outer peripheral shape of the retaining member 10 is formed into a tongue shape when viewed from above. In this embodiment, for the convenience of explanation, it is recorded that a gap is generated between the receiving member 13 and the displacement element 14 described later, but any of the following situations may also occur: a situation in which a gap is generated as the displacement element 14 is displaced, a situation in which the receiving member 13 and the displacement element 14 are in contact (a situation in which there is no gap).

(Keep the object)

The holding member 10 can be used to hold an object. Therefore, the holding member 10 includes the concept of a structure that can be used as a so-called container holder or container support. The so-called holding object refers to what is held by the holding member 10, and can be exemplified by a container, a stack of containers and lids, or a container and lid in one body. The holding object includes: what is held by the upper edge of the through hole of the holding member, or what is held by the circumferential surface of the through hole of the holding member.

(Base plate)

In the retaining member 10, a retaining body 11 is provided on a base plate 12. In this example, the retaining body 11 arranges a plurality of displacers 14 and a receiving member 13 described later on the upper surface (upper surface of the plate) of the base plate 12. However, this is not limited to the case where the retaining member 10 has the base plate 12. If the retaining body 11 is not disassembled, that is, the combination of the plurality of displacers 14 described later is not disassembled into a single unit, the base plate 12 can be omitted as long as the displacers 14 do not separate from the retaining body 11. The material of the base plate 12 is not particularly limited, and is not particularly limited to metal, plastic, wood, glass, ceramic, etc., but from the viewpoint of excellent strength, the base plate 12 is preferably made of metal. On the base plate 12, an auxiliary hole 17 is formed at a position corresponding to the through hole 16 described later. The auxiliary hole 17 is formed in the following shape: when the size of the through hole 16 is enlarged, it is roughly inscribed with the shape of the circumferential surface 16A of the through hole 16 when the retaining member 10 is viewed from above. As the size of the through hole 16 changes in a manner that the size of the through hole 16 decreases, the edge 17A of the auxiliary hole 17 is located outside the through hole 16 when the retaining member 10 is viewed from above.

(Maintain body)

The retaining body 11 has a through hole 16, and has a plurality of displacers 14 that form at least a portion of the through hole 16. The through hole 16 is formed by a plurality of displacers 14. Furthermore, the retaining body 11 has a receiving member 13 on the outer side of the displacer 14, when the direction toward the through hole 16 is regarded as the inner side. In more detail, the retaining body 11 has an annular structure 15 formed by a plurality of displacers 14, and further has a receiving member 13 on the outer side of the annular structure 15. In addition, the retaining member 10 may also configure the displacer 14 in a non-annular shape. Furthermore, for example, as an example of the retaining member 10, the through hole 16 may also be formed by a combination of the displacer 14 and a non-displaced non-displaced member. In this example, the shifter 14 is configured in a non-annular shape.

(Perforation)

The through hole 16 of the holding body 11 is formed so that its size can be changed according to the displacement of the displacement element 14 as described later. The through hole 16 has a diameter sufficient to allow the holding object to pass therethrough. The through hole 16 has a circumferential surface portion 16A and an upper edge portion 16B. In the description of the sealed device, the object to be retained is a container 200, that is, a container 200 having a main body 210 and a bottom 220 with an opening on the upper side, a space 230 surrounded by the main body 210 and the bottom 220 formed inside, and a flange 240 extending outwardly on the upper end (upper edge 250) side of the main body 210, the circumferential surface 16A faces the outer peripheral surface 210A of the main body 210 (the outer peripheral surface of the container 200), and the upper edge 16B faces the flange 240. In addition, the flange 240 may be flat or curved. When the container is used for explanation in the following description, the following description is continued: the object to be held is the container 200 as described above, the shape of the main body 210 is a shape that tapers from the upper end to the lower end, and the main body of the container 200 is a shape that opens on the upper surface side. In addition, the upper edge 16B indicates the portion forming the upper edge of the through hole 16 when assuming that the container 200 passes through the holding member 10 in a generally vertical direction. When the container 200 is inserted relative to the holding member 10, it is preferred to insert the container 200 in a manner that penetrates the through hole 16 from the upper edge 16B side.

The size of the through hole 16 changes within a predetermined range according to the displacement of the displacement element 14. It is predetermined when the size of the through hole 16 is in an expanded state. The expanded state is a state in which the size of the through hole 16 is increased as determined by conditions such as the size of the object to be held or the configuration of the displacement element 14. The size of the through hole 16 when the displacement element 14 is displaced to a position in contact with the limiting wall portion 21. In addition, the size of the through hole 16 in a reduced state is also predetermined. The reduced state is a state in which the size of the through hole 16 is reduced as determined by conditions such as the size of the object to be held or the configuration of the displacement element 14. For example, in the example referred to in the later-described Modification 1, the size of the through hole 16 is determined when the displacement element 14 is displaced until the elastic member 22 described later becomes the natural length. Also, for example, in the case where the object to be held is a container 200 having a shape tapering downward, in terms of the relationship between the object to be held and the contracted state, a size slightly larger than the size of the lower end of the container 200 can be determined as the size of the through hole 16 corresponding to the contracted state of the through hole 16. In terms of the relationship between the size of the object to be held and the expanded state, a size slightly larger than the size of the upper end of the container 200 (excluding the flange 240) can be determined as the size of the through hole 16 corresponding to the expanded state of the through hole 16. In addition, when the size of the through hole 16 is changed, the size of the through hole 16 may be changed in a manner that the shapes before and after the change are similar to each other, or the size of the through hole 16 may be changed in a manner that the shapes are not similar to each other. In addition, when the size of the through hole 16 is reduced, it also includes the situation where the size of the through hole 16 is substantially zero.

(Specific size of the perforation)

The size of the through hole 16 is set as follows: when the central CT of the through hole 16 is assumed to be consistent with the position of the displacement element 14, one through hole 16 is arranged in the front and the other through hole 16 is arranged in the back, when the other through hole 16 is exposed, the other through hole 16 is smaller than the first through hole 16; when the first through hole and the other through hole 16 are consistent, the first through hole 16 and the other through hole 16 are the same size; when the other through hole 16 is not exposed and is not the same as the first through hole 16, the other through hole 16 is larger than the first through hole 16. The size of the through hole 16 and the auxiliary holes 17 and 18 is determined by the diameter of the largest inscribed circle of the through hole 16 and the diameter of the auxiliary holes 17 and 18.

(Shifter)

In the retaining member 10, a plurality of displacers 14 are arranged in a ring shape. Here, the so-called arrangement in a ring shape, when a predetermined position is taken as a reference position (the center CT of the through hole 16), means a state in which the arrangement is made to surround the reference position. When arranged in a ring shape, when the direction away from the reference position (the direction extending outward from the reference position along the surface with the thickness direction of the retaining member 10 as the normal) is taken as the line of sight direction, the situation in which a plurality of adjacent displacers 14 overlap is included. The so-called displacer 14 refers to a member (a displaceable segment) that moves or rotates its position or the like under the action of extrusion pressure or electrical or magnetic properties from the outside. Examples of the displacer 14 include a mover or a rotator. A displacer is a tangible object that moves its position. A rotator is a tangible object that performs rotational movement. The displacer 14 only needs to be configured in a manner such that at least a portion of it can be identified from the through hole 16. When the size of the through hole 16 is a predetermined size, there is no prohibition on the existence of a portion (some) of the displacers 14 that is not exposed in the through hole 16.

(Layout of displacement sub-units)

Regarding the layout of the shifters 14, when the direction away from the reference position is taken as the line of sight, the adjacent plurality of shifters 14 overlap, and the adjacent shifters 14 are in contact with each other. Moreover, the shifters 14 arranged in a ring form a ring-shaped structure 15 as a whole. The ring-shaped structure 15 has a penetration portion (a portion penetrating in the direction along the Z-axis direction) formed on the inner side, and the penetration portion becomes a penetration hole 16. Therefore, the plurality of shifters 14 form the penetration hole 16. However, this is not limited to the case where the penetration hole 16 is formed in the penetration portion formed by the shifter 14 being arranged in a ring. For example, the case where the penetration hole 16 is formed by the shifter 14 and the wall portion 24 is not excluded. As shown by the dotted line, as the displacement element 14 slides in the direction of the arrow (displacement direction T), the size of the exposed area ER changes, and as the size of the exposed area ER changes, the size of the through hole 16 changes.

Furthermore, the plurality of displacers 14 are arranged in a ring shape so that the shape of the through hole 16 becomes a roughly regular polygon when the retaining body 11 is viewed from above (when the retaining member 10 is viewed from above), but the arrangement (layout) of the plurality of displacers 14 is not limited to this example. For example, the plurality of displacers 14 can be arranged so that the shape of the through hole 16 becomes a shape close to a rectangle, or the plurality of displacers 14 can be arranged so that the shape of the through hole 16 becomes a polygon other than a regular polygon. Four displacers 14 are arranged, and the through hole 16 is formed into a rectangular shape. Furthermore, in this example, the displacer 14 is formed into a roughly right-angled triangle shape when the retaining member 10 is viewed from above, and the length of one side facing the end face side of the through hole 16 is longer than the length of one side extending at a roughly right angle to the piece. As the displacement element 14 slides in the direction of the arrow (displacement direction T), the size of the exposed area ER changes as shown by the dotted line, and as the size of the exposed area ER changes, the size of the through hole 16 changes. In addition, when the side surface of the displacement element 14 is set to a curved shape as described later, multiple displacement elements 14 can be used to arrange the multiple displacement elements 14 in a manner that the through hole 16 becomes a circle.

(Exposed area of the displacement particle)

In the surface of the displacement element 14 (e.g., the first side surface 14A1 in the side surface 14A), the area of the circumferential surface 16A forming the through hole 16 becomes the exposed area ER exposed toward the through hole 16. The size of the exposed area ER is determined according to the size of the through hole 16. In at least a part of the displacement element 14, as the displacement element 14 is displaced in the displacement direction T, the exposed area ER of the displacement element 14 exposed at the circumferential surface 16A of the through hole 16 changes. The smaller the size of the through hole 16 is, the smaller the exposed area ER of the displacement element 14 forming the through hole 16 is. Furthermore, as the exposed area ER of the displacement element 14 decreases, the area (overlapping area CR) on the surface of the displacement element 14 that is in contact with the adjacent displacement element 14 and overlapped by the adjacent displacement element 14 increases. The larger the size of the through hole 16, the greater the exposed area ER of the displacement element 14. Furthermore, as the exposed area ER of the displacement element 14 increases, the area (overlapping area CR) on the surface of the displacement element 14 that is overlapped by the adjacent displacement element 14 decreases. As described above, in the retaining member 10, as each displacement element 14 is displaced in the displacement direction T, the exposed area ER of each displacement element 14 exposed on the circumferential surface 16A of the through hole 16 changes. In addition, as an example, if the size of the through hole 16 can be changed, it does not prohibit the size of the exposed area ER from being changed for a portion of the displacer 14.

(Shape of the displacement particle)

Each displacer 14 has a triangular shape when viewed from above, and is formed into a triangular plate with a predetermined thickness. In addition, the plurality of displacers 14 are formed roughly uniformly. However, this does not limit the shape of the displacer 14, and does not prohibit at least a portion of the plurality of displacers 14 from having a different shape relative to other displacers 14. For example, the shape of the plurality of displacers 14 forming the through hole 16 may also be a triangle, a trapezoid, or a shape with a curved portion.

(Size of the displacement particle)

The sizes of the plurality of shifters 14 are formed to be roughly uniform. However, this does not limit the situation where at least a portion of the plurality of shifters 14 have different sizes.

(Material of the displacement particle)

The material of the displacer 14 is not particularly limited to metal, plastic, wood, glass, ceramic, etc. From the perspective of excellent sliding properties and excellent molding easiness, the material of the displacer 14 is preferably plastic. When the displacer 14 is made of plastic, the displacer 14 is preferably provided with cushioning properties. From this perspective, the displacer 14 is preferably made of a porous polymer material. Examples of porous polymer materials include foamed polymer materials. In addition, the plastic may be elastic or inelastic. In the case where the displacer 14 is easily elastically deformed, the size of the through hole 16 can be smoothly changed regardless of whether the side surface of the displacer 14 is set to a curved shape or the through hole 16 is arranged in a plurality of displacers 14 in a circular shape. In addition, from the perspective of the strength of the displacer 14 and the small and excellent wear caused by friction during sliding, the material of the displacer 14 is preferably metal (including alloy). In the case where the material of the displacer 14 is metal, the material of the displacer 14 can be specifically exemplified by iron, copper, aluminum, stainless steel, etc. From the perspective of difficulty in rusting, the material of the displacer 14 is preferably aluminum alloy or stainless steel.

(Displacement direction of the displacer)

Each displacer 14 slides on the upper surface (upper surface of the plate) of the base plate 12. Therefore, the displacer 14 is displaced in the surface direction (XY plane direction) of the base plate 12. At this time, when the retaining body 11 is viewed from above, the displacement direction T of the displacer 14 is predetermined for each displacer 14. The displacement direction T of the displacer 14 is determined according to the shape and configuration of the displacer 14. The displacement direction T of each displacer 14 is determined according to the orientation of the base 140 of the displacer 14. In this example, the direction along the extension direction of the base 140 of the triangle forming the displacer 14 is set as the displacement direction T, and the displacer 14 is linearly displaced along the displacement direction T. At this time, by setting the direction as described above as the displacement direction T, adjacent displacers 14 can be linked as described later. The displacer 14 is linearly displaced along the displacement direction T, but the displacement direction T is not limited to the linear case. For example, the displacement element 14 can also be configured to perform arc-shaped displacement. In addition, when the displacement element 14 presents a triangular shape when viewed from above, the base 140 is determined to be the shortest of the three sides, but this is determined for the sake of convenience and is not limited to this. When performing arc-shaped displacement, the displacement element 14 is preferably made of elastically deformable materials such as rubber.

(Linkage of adjacent shifters)

The adjacent displacers 14 are linked as described above. The so-called linkage means that as one displacer 14 is displaced, the adjacent displacer 14 is also displaced. The linkage structure is not particularly limited, but is realized by using the configuration structure of the adjacent displacers 14. The adjacent displacers 14 are in contact with each other on their side surfaces 14A (first side surface 14A1). Moreover, one of the adjacent displacers 14 applies extrusion pressure to the other displacer 14. By the action of the extrusion pressure, the other displacer 14 is displaced.

When one of the adjacent displacers 14 moves along the guide portion 20 described later corresponding to the one displacer 14, an extrusion pressure is applied to the other displacer 14, and the other displacer 14 moves along the guide portion 20 corresponding to the other displacer 14 based on the extrusion pressure. When one displacer 14 moves along the displacement direction T, an extrusion pressure may be applied to the other displacer 14 in a manner of extruding in an oblique direction relative to the extension direction of the guide portion 20 of the other displacer 14. Therefore, the other displacer 14 is displaced along the guide portion 20 by the extrusion pressure received from the one displacer 14. In addition, when the guide part 20 is displaced, it is not limited to the guide part 20 and the displacement element 14 moving while in contact with each other. In the case where the guide part 20 and the displacement element 14 are partially in contact and move without losing the function of the guide part 20, it may include the situation where the guide part 20 and the displacement element 14 are temporarily separated.

(Sliding of adjacent shifters)

The adjacent displacers 14 slide against each other. At this time, they slide against each other along the determined displacement direction T relative to each displacer 14. The adjacent displacers 14 contact each other at their side surfaces 14A (first side surface 14A1), and the adjacent displacers 14 are displaced along the determined displacement direction T respectively in a manner that their side surfaces 14A rub against each other. In addition, the concept of the two sliding includes the situation that the two slide smoothly and the situation that the two move while rubbing against each other. In the case where the adjacent displacers 14 slide, it is preferred that friction force acts between the adjacent displacers 14. In this case, it is preferred that the friction force in the sliding direction of the adjacent displacers 14 is greater than the friction force in the sliding direction of the adjacent displacers 14. Furthermore, when the adjacent shifters 14 slide, it includes not only the situation where the adjacent shifters 14 slide in a state of always being in contact, but also the situation where there is a moment when the adjacent shifters 14 are separated.

Furthermore, the adjacent displacement elements 14 are all arranged on the base plate 12 to avoid the adjacent displacement elements 14 from overlapping each other in the vertical direction. Thus, by making the thickness of the adjacent displacement elements 14 uniform, it is possible to avoid the formation of unevenness along the circumferential direction of the through hole 16 on the upper edge portion 16B of the through hole 16. In addition, on the upper edge portion 16B of the through hole 16, the positions of the upper surfaces 14B of the adjacent displacement elements 14 are uniform. By constructing in the above manner, when the retaining member 10 is used in the sealing device described later, the contact position of the upper edge portion 16B of the through hole 16 in the retaining member 10 and the flange portion 240 of the container 200 in the up-down direction is roughly uniform, and the container 200 can be pressed against the extrusion body 310 described later at roughly the same time point.

(Connecting components)

The retaining body 11 is provided with a receiving member 13 on the outer side of the annular structure 15. The receiving member 13 can function as a structure having a limiting structure 19 described later. The receiving member 13 is formed in an annular shape, and the outer peripheral surface 13A of the receiving member 13 is formed in a shape corresponding to the outer peripheral surface 11A of the retaining body 11. The inner peripheral surface 13B of the receiving member 13 is formed in a shape corresponding to the outer peripheral surface 15A of the annular structure 15. The receiving member 13 is fixed to the base plate 12, and by forming the annular structure 15 in a manner facing the inner peripheral surface 13B of the receiving member 13, the annular structure 15 can be suppressed from being offset relative to the base plate 12, and therefore, the displacement element 14 can be suppressed from being offset relative to the base plate 12.

(Material of supporting components)

The material of the receiving member 13 is not particularly limited. From the perspective of ease of manufacturing, it is preferably the same material as the displacement element 14.

The receiving member 13 is formed by one member, but the receiving member 13 can also be formed by a combined structure formed by combining a plurality of divided parts (not shown).

(Restriction structure)

The retaining body 11 has a limiting structure 19. The limiting structure 19 is a structure for limiting the displacement direction T (displacement direction limiting structure). The limiting structure 19 limits the displacement direction T of at least a portion of the displacement element 14. The limiting structure 19 has a guide portion 20. The guide portion 20 is formed on the receiving member 13. The guide portion 20 shown in this example limits the displacement direction T in a manner that the displacement element 14 linearly displaces from the first position to the second position.

(1st and 2nd positions)

The first position is the position of the displacer 14 determined when the size of the through hole 16 becomes a predetermined enlarged state (e.g., the position of the displacer 14). The second position is the position of the displacer 14 determined when the size of the through hole 16 becomes a predetermined contracted state (e.g., the position of the displacer 14). In addition, the situation where the limiting structure 19 has a guide portion 20 is an embodiment of the limiting structure 19, and the limiting structure 19 is not limited to this. In the description of the first embodiment, for the convenience of description, the situation where the limiting structure 19 is a structure with a guide portion 20 is taken as an example to continue the description.

(Guidance Department)

The guide portion 20 only needs to be provided for at least a portion of the displacer 14, and is provided on each displacer 14. The guide portion 20 limits the movement of the displacer 14 by limiting the displacement direction of the displacer 14. The guide portion 20 guides the displacer 14 provided corresponding to each displacer 14 toward a predetermined direction. The guide portion 20 is formed by a guide wall portion 23 facing one side surface of the displacer 14 (the second side surface 14A2 formed at the position of the bottom edge 140) in the receiving component 13. The guide portion 20 guides the movement of the displacer 14 in a manner that the displacement direction T of the displacer 14 becomes the direction along the wall surface of the guide wall portion 23 of the guide portion 20 corresponding to the displacer 14. The wall direction of the guide wall portion 23 forming the guide portion 20 is consistent with the extension direction of the base of the triangle forming the shape of the displacer 14 (the surface direction of the second side surface 14A2). In this example, the base directions of adjacent displacers 14 are different (the surface direction of the second side surface 14A2), so the wall directions of the guide wall portion 23 corresponding to each displacer 14 are also different from each other. The length of the guide portion 20 is preferably roughly consistent with the displacement range of the displacer 14 (the displacement range of the displacer 14 when the position of the displacer 14 is moved from the first position to the second position) or greater than the displacement range. In addition, if the displacement direction T of the displacer 14 can be limited, the structure of the guide portion 20 is not limited.

(Restriction wall)

The retaining body 11 preferably has a limiting wall portion 21 that limits the displacement distance of at least one displacer 14. The limiting wall portion 21 has a wall surface 21A that contacts the displacer 14 when the displacer 14 is displaced to a predetermined position. For example, when the displacer 14 moves to the first position in the displacement direction T, the first side surface 14A1 of the displacer 14 contacts the wall surface 21A of the limiting wall portion 21, and the displacement direction T from the first position to the direction opposite to the direction toward the second position is limited. Therefore, the limiting wall portion 21 limits the displacement distance of the displacer 14.

The limiting wall portion 21 is formed on the receiving member 13 and shares the end edge of the limiting wall portion 21 with the end edge of the guide portion 20. The angle formed by the wall surface 21A of the limiting wall portion 21 and the wall surface of the guide wall portion 23 of the guide portion 20 is an acute angle. In this example, the receiving member 13 is formed with a substantially V-shaped wall portion 24 on each displacement member 14 when the retaining member is viewed from above, and the wall portion 24 forms the limiting wall portion 21 and the guide wall portion 23. Moreover, the V-shaped wall portion 24 is formed in a ring-shaped arrangement to correspond to the configuration of the displacement member 14. In addition, at the positions of the end edge of the limiting wall portion 21 and the end edge of the guide portion 20, a curved wall portion 25 that is curved into a C-shape when the receiving member 13 is viewed from above is formed. By bending the wall surface 25, the corner (vertex 141) of the displacer 14 can be prevented from contacting the edge of the limiting wall 21 and the edge of the guide portion 20.

[1-2 Function and Effect]

According to the first embodiment, as the displacement element 14 is displaced, the exposed area ER of the displacement element 14 forming the circumferential surface 16A of the through hole 16 changes, and the size of the through hole 16 can be changed. For a plurality of containers 200 of different sizes as the objects to be held, the container 200 can also be in contact with the upper edge 16B of the through hole 16 on the same holding member 10, and the container 200 can be supported on the upper edge 16B of the through hole 16.

Furthermore, according to the retaining member 10 of the first embodiment, the size of the through hole 16 can be changed along with the displacement of the displacer 14, so as to correspond to the situation where the size of the main body 210 of the container 200 itself changes.

For example, when the object to be retained is a container 200, and the container 200 has a main body 210 with an opening on the upper side and a bottom 220, a space 230 is formed inside, and a flange 240 extending outwardly is provided on the upper end side of the main body 210, when the retaining component 10 retains the object to be retained through the through hole 16, the circumferential surface 16A faces the outer peripheral surface 210A of the main body 210 (the outer peripheral surface of the container 200), and the upper edge 16B faces the flange 240. When the outer peripheral surface 210A of the body 210 is tapered downward, the size of the cross section of the body 210 is smaller at the lower side (the portion close to the bottom 220) than the size near the flange 240. When the container 200 is arranged inside the through hole 16 of the retaining member 10 and the retaining member 10 is moved upward, the size of the outer peripheral surface 210A of the body 210 is smaller than the size of the through hole 16 when the through hole 16 of the retaining member 10 is in a shrunk state, and the retaining member 10 is simply pulled upward. Then, if the size of the outer circumferential surface 210A of the body 210 is the same as the size of the through hole 16 of the retaining member 10 when the through hole 16 is in the contracted state, the through hole 16 of the retaining member 10 contacts the outer circumferential surface 210A of the body 210. If the weight of the container 200 is greater than a predetermined weight, the retaining member 10 contacts the body 210 of the container 200 while sliding upward relative to the body 210 of the container 200. At this time, the container 200 may move upward together with the retaining member 10, or may not move. The retaining member 10 contacts the main body 210 of the container 200 while rubbing in the upward direction, and the size of the through hole 16 changes (expands) by the displacement of the displacer 14 corresponding to the size of the main body 210 of the container 200. Moreover, if the upper edge 16B of the through hole 16 of the retaining member 10 contacts the flange 240 of the container 200 in the middle of the upward movement of the retaining member 10, the retaining member 10 retains the container 200 and moves upward together with the container 200. As described above, according to the retaining member 10, the size of the through hole 16 can be changed, and the following state can be set: when the size of the main body 210 of the container 200 itself changes, the upper edge 16B of the retaining member 10 is also made to contact the flange 240.

In the retaining member 10 of the sealing device 1001 of the present embodiment, a positioning structure 35 is provided on the upper surface side (+Z direction side) of the protective plate 33. The positioning structure 35 has a plurality of rotating members 43. In the retaining member 10 shown in this example, a support shaft 42 is provided according to the rotating member 43. Furthermore, in the retaining member 10 shown in this example, a support shaft 42 is arranged in an area on the protective plate 33. The support shaft 42 supports the rotating member 43. In this example, the support shaft 42 has the following structure: from the head portion 47 formed by the portion on the upper end side of the support shaft 42, it penetrates the hole portion 48A of the bearing 48 of the rotating member 43, thereby reaching the protective plate 33. The support shaft 42 is fixed to the protective plate 33. The predetermined portion of the front end 42A side (-Z direction side) of the support shaft 42 enters and exits the protective plate 33, and the portion of the support shaft 42 that enters and exits the protective plate 33 is fixed to the protective plate 33. At this time, the method of fixing the portion of the support shaft 42 that enters and exits the protective plate 33 to the protective plate 33 is not particularly limited. For example, a threaded structure (so-called half thread) can be formed on the portion of the outer peripheral surface from the front end (lower end) of the support shaft 42 to a predetermined position (a predetermined position toward the upper side), so that at least a portion of the portion formed with the threaded structure on the protective plate 33 is screwed, thereby fixing the portion of the support shaft 42 that enters and exits the protective plate 33 to the protective plate 33.

(rotating component)

The rotating member 43 can rotate about the support shaft 42. The rotating member 43 includes: a bearing 48 having a hole portion 48A penetrating vertically, an arm 44 connected to a predetermined position on the upper end side of the outer peripheral surface of the bearing 48 and extending in a direction away from the bearing 48, and a pin 45 hanging down from the front end 44A of the arm 44. The configuration of the rotating member 43 is not particularly limited as long as it can play a function of defining the position of the cover body. Two sets of two rotating members (a combination of a rotating member 43A and a rotating member 43B, and a combination of a rotating member 43C and a rotating member 43D) (i.e., four rotating members 43) are arranged in a manner adjacent to each other on the outer side of the through hole 16. The combination of one set of rotating members 43 (the combination of rotating members 43A and rotating members 43B) and the combination of another set of rotating members 43 (the combination of rotating members 43C and rotating members 43D) are arranged in a manner that they are located at positions along the outer periphery of the through hole 16 and are located at positions on opposite sides (-X direction side and +X direction side) across the center CT of the through hole 16. The combination of each rotating member 43, 43 is configured in a manner that the rotation direction K4 of one rotating member 43 and the rotation direction K4 of the other rotating member 43 are opposite to each other. For example, taking the combination of the rotating member 43A and the rotating member 43B as an example, if the rotating member 43A rotates in the +K4 direction, the rotating member 43B rotates in the -K4 direction. If the rotating member 43A rotates in the -K4 direction, the rotating member 43B rotates in the +K4 direction. Thus, the rotating member 43A and the rotating member 43B can rotate in a manner such that their respective pins 45 approach each other, or can rotate in a manner such that their respective pins 45 move away from each other. The aspect that the rotating member 43C and the rotating member 43D can perform a rotational action in which the rotation direction K4 becomes opposite to each other is also the same.

(Gear)

The structure for performing the rotational action of rotating the rotation direction K4 in opposite directions is not particularly limited. It is realized by the meshing structure of the gears 46, 46. For example, in the case of the combination of the rotating members 43A and 43B, the gear 46 is fixed to the lower end side of the bearing 48 of the rotating member 43A, and the gear 46 is also fixed to the lower end side of the bearing 48 of the rotating member 43B. The structure is as follows: the gears 46, 46 arranged on the rotating members 43A and 43B are meshed, and rotate in opposite directions. The structure of the gear 46 is also the same in the combination of the rotating member 43C and the rotating member 43D.

A pin 45 is provided in the rotating member 43, but the lower end (front end 45A) of the pin 45 is preferably located below the upper surface of the protective plate 33 and slightly above the upper surface 14B of the displacement element 14.

In addition, the pin 45 extends obliquely downward from the connection portion with the arm 44 toward the front end 45A and toward the center CT, which is an example. For example, the pin 45 may also extend straight downward. In addition, the pin 45 may be partially or completely bent or curved.

(Arm rotation range)

The rotation range (maximum value of the rotation angle in the direction of arrow K4) of the arm 44 in the rotation member 43 is not particularly limited. For example, when the retaining member 10 is viewed from above, the rotation range of the arm 44 can be determined within the range where the front end 45A of the pin 45 is limited within the formation area of the auxiliary hole 18 of the protective plate 33. In addition, the rotation range of the arm 44 can be determined within the range where the front end 45A of the pin 45 extends outside the formation area of the auxiliary hole 18 of the protective plate 33. The position of the arm 44 when the front end 44A of the arm 44 is the closest to the center CT is not particularly limited. Positioning is performed for each combination of the rotation members 43, 43. For example, regarding the positioning of the arm 44 of the rotating member 43A and the arm 44 of the rotating member 43B, when the cover is arranged on the upper side of the container, the arm 44 of the rotating member 43A and the arm 44 of the rotating member 43B can be respectively rotated in the +K4 direction and the -K4 direction according to the size of the cover, so as to perform the positioning of the arm 44 of the rotating member 43A and the arm 44 of the rotating member 43B. In addition, when the container is held by the upper end edge 16B of the through hole 16, the arm 44 of the rotating member 43A and the arm 44 of the rotating member 43B can also be respectively rotated in the +K4 direction and the -K4 direction according to the size of the container. The positioning of the arm 44 is also the same for the arm 44 of the rotating member 43C and the arm 44 of the rotating member 43D.

The rotating member 43 preferably applies force by rotating the front end 44A of the arm 44 in a direction close to the center CT of the through hole 16. In this case, when the container and the cover are held by the holding member 10, even if the rotating member 43 rotates in a manner that the front end 44A of the arm 44 is away from the center CT of the through hole 16, the rotating member 43 can be rotated in a direction that the front end 44A of the arm 44 is close to the center CT of the through hole 16 by removing the container and the cover from the holding member 10, and roughly return to the original position.

(Avoidance section)

In the case where the rotation range of the arm 44 is determined within the range where the front end 45A of the pin 45 extends out of the formation area of the auxiliary hole 18 of the protective plate 33, it is preferable to form an escape portion 49. In this case, even if the front end 45A of the pin 45 is located below the upper surface of the protective plate 33, it is possible to avoid the concern that the front end 45A of the pin 45 hits the protective plate 33 as the rotating member 43 rotates. The escape portion 49 is formed as an arc-shaped cutout portion when the retaining member 10 is viewed from above. This is an example, and the structure of the escape portion 49 is not limited to the example described above. In addition, the size of the escape portion 49 can be appropriately determined according to conditions such as the size of the container or the cover.

(Extension)

In the positioning structure 35, it is preferred to provide a first extension 50 and a second extension 51 on the rotating member 43 as extensions extending in a direction away from the support shaft 42. The first extension 50 and the second extension 51 are formed at the outer peripheral end of the gear 46, and are portions protruding further outward than the gears of the gear 46. The first extension 50 is formed at a position where the front end portion 44A of the arm 44 rotates in a direction away from the center CT of the through hole 16 when contacting the protruding member described later. The second extension 51 is formed at a position where the front end portion 44A of the arm 44 contacts the rotation limiting member 52 when the front end portion 44A of the arm 44 rotates in a direction approaching the center CT of the through hole 16. Therefore, the rotation limiting member 52 is arranged at a position that can contact the second extension 51. When the front end 44A of the arm 44 of the rotating member 43 rotates in a direction close to the center CT of the through hole 16, the rotation of the rotating member 43 can be stopped at the position where the second extension 51 contacts the rotation limiting member 52. The first extension 50 and the second extension 51 are arranged on the rotating members 43B and 43D, and the rotating members 43A and 43C are linked to the rotation of the rotating members 43B and 43D through the action of the gear 46. Therefore, the rotation range of the rotating members 43A and 43C is limited according to the restriction of the rotation of the rotating members 43B and 43D.

Next, the effect of the sealing device 1001 of the present embodiment will be described. The sealing device is usually in a state where the sealing portion 1004 is located at the first position and no container or the like is arranged on the retaining portion 1003. Furthermore, when the user seals the lid on the container, the container is retained on the retaining member 1 of the retaining portion 1003. At this time, the container is retained by inserting the lower end of the container from above the retaining member 1, and the lower end of the curled portion formed at the upper end of the container abuts against the inner end of the shifter of the retaining member 1. Then, the user takes the rod 1021 of the operating portion 1005 in his hand and moves the sealing portion 1004 from the first position to the second position. At this time, a locking part 1024 is provided on the operating part 1005, and the locking part 1024 limits the displacement in the up and down directions by the locking receiving part 1023. Therefore, if the user wants to operate in the direction of lowering the rod 1021 before the sealing part 1004 is located at the second position, that is, when the user reaches the second position from the first position, the locking part 1024 abuts against the top surface 1025 of the locking receiving part 1023, thereby limiting the excessive operation of the rod 1021. Therefore, the downward movement of the heater 1013 is also limited by the operation of the rod 1021.

If the sealing portion 1004 is located at the second position, the locking portion 1024 reaches the position where the lock release portion 1026 is formed. At the position where the lock release portion 1026 is formed, even if the user performs an operation to rotate the rod 1021 in the downward direction, the displacement of the locking portion 1024 in the upward and downward directions is not restricted. Therefore, the user can rotate the rod 1021 in the downward direction. In addition, if the rod 1021 is rotated as described above, the gear 1019 connected to the rod via the shaft member 1022 rotates, and the gear 1020 engaged with the gear 1019 moves downward. The heater 1013 is installed at one end of the gear 1020, so if the gear 1020 moves downward, the heater 1013 moves downward accordingly. That is, if the user rotates the lever 1021 downward, the heater 1013 can be lowered accordingly.

By configuring as described above, in the sealing device 1001, only when it is in the second position, that is, the position where the heater 1013 can make the container and the cover body join (in this embodiment, it is directly above the container and the cover body), the user can operate the rod 1021 reliably, and the cover body and the edge of the container can be reliably joined by operating the rod 1021. In addition, as described above, in places other than the second position, the action of the heater 1013 descending is restricted, so that the inadvertent action of the heater 1013 descending in a place without a cover body or a container, or the inadvertent descending of the heater in the heating state, such as when cleaning, can be reliably eliminated.

Furthermore, according to the sealing device of the present embodiment, since the positioning member in the holding member 1 is provided, the lid can be positioned with good accuracy with respect to the container. Furthermore, if the sealing portion 1004 moves from the first position to the second position, the positioning member transitions from the state of positioning the lid to the state of releasing the positioning of the lid. At this time, the lid maintains the state already positioned by the positioning member, so even when the sealing portion 1004 approaches, the positioning state caused by the positioning member is released and the lid remains in the already positioned position. Therefore, the lid can be joined with the container in a state where the positioning accuracy of the lid with respect to the container is greatly improved. Furthermore, when the heater 1013 descends and the lid is joined with the container, the positioning member is located at a position that does not interfere with the heater 1013. Therefore, the presence of the positioning member can eliminate the problem of defects in the connection between the lid and the container.

Furthermore, the sealing device of this embodiment can significantly reduce the vibration or impact applied to the container because the retaining part 1003 does not move and the sealing part 1004 moves from the first position to the second position. Therefore, it can prevent the container from being impacted and the contents from scattering or leaking out of the container. In this way, the scattering of food and drinks as contents around the sealing device can be significantly reduced, so that the hygienic state can be maintained for a long time and the user can use it in a comfortable state.

If a predetermined time has passed since the heater started squeezing the lid and the container, the user is informed that the sealing of the container is complete, for example, by changing the color of the light or playing a sound message. Upon seeing the display (notification), the user operates the rod in the direction opposite to the H direction. If the rod is operated in this direction, the gear moves upward through the above-mentioned transmission mechanism, and the heater also rises from the position connected to the lid. Moreover, after returning the rod to the predetermined position, the sealing part moves from the second position to the first position. The user takes out the container held by the holding member for food and drink.

According to the sealing device of this embodiment, the lid can be positioned with good precision on the container, which can greatly reduce the deviation after the user seals. In addition, the sealing device of this invention uses a single-piece lid to seal the container, so compared with the situation where the long strip body rolled into a roll sequentially penetrates the sealed container on one side, the loss of the components forming the lid can be greatly reduced. In addition, according to the sealing device of this invention, it is not necessary to set the long strip body in the sealing device, so the sealing device can also be miniaturized, which is also very advantageous when it is set in a limited space, such as in a store.

Next, the second embodiment of the sealing device of this invention is carried out. The sealing device of this embodiment includes: a base portion, a holding portion 1003, a sealing portion 1004, and an operating portion 1005. In addition, the description and illustration of the storage portion described in the previous embodiment are omitted in this embodiment. In addition, since the structure of the holding portion 1003 of this embodiment is the same as that described previously, the description here is omitted.

As shown in FIGS. 6 to 9 , the base portion is a portion that serves as a base for the sealing device 1001. The bottom plate portion, right side plate, left side plate, and upper plate portion of the base portion are joined together by welding or the like. Furthermore, on the upper plate, a through-hole portion that penetrates in the plate thickness direction of the upper plate portion is formed at a portion corresponding to a portion where a through-hole of the retaining portion 1003 is opened so as to be formed in order to mount and fix the retaining portion 1003. Furthermore, the upper plate is joined together by the right side plate and the left side plate at a position further inward than the left and right ends of the upper plate, and a guide rail 1017 constituting a moving portion is provided at an end further to the right than the right side plate of the upper plate and at an end further to the left than the left side plate of the upper plate. The sealing part and the operating part described later can move along the guide rail. In addition, the sealing device 1001 shown in FIG. 6 is formed in a manner that the length of the long side direction (front-back direction) of the bottom plate of the base is fixed, but it can also be constructed in a manner that the end of one end side (for example, the front side) of the bottom plate and/or the end of the other end side (for example, the rear side) of the bottom plate can only be extended and retracted by a predetermined distance. If the end of one end side and/or the end of the other end side of the bottom plate is extended and retracted as described above, the stability of the sealing device 1001 can be increased, and the user can use the sealing device 1001 with peace of mind in a more stable state.

The sealing device 1001 of the present embodiment is constructed as follows: the sealing part 1004 is housed in the upper cover body 1027 and the lower cover body 1028. The upper cover body 1027 is provided with a handle 1029 on the front surface. The user can move the handle 1029 in the hand to the front and rear directions. When moving as described above, the moving body 1018 engaged with the guide rail 1017 moves along the guide rail 1017. The lower cover body 1028 is provided with an operation panel 1030 constituting an operation part on the front surface. The operation panel 1030 is used to operate the sealing device 1001, for example, various adjustments and operations such as switching the power of the sealing device 1001 or adjusting the set temperature of the heater 1013 can be performed. In addition, the operation panel 1030 can be arbitrarily selected from previously known ones, such as a button-type operation panel or a touch panel-type operation panel. Moreover, other than these can also be appropriately used.

As described above, the sealing part 1004 is accommodated and arranged inside the upper cover body 1027 and the lower cover body 1028. The sealing part 1004 of this embodiment includes a driving motor 1031 and a transmission mechanism 1032, and is configured as follows: the driving action of the driving motor 1031 is transmitted to the transmission mechanism 1032, and the heater body 1015 of the heater 1013 performs a descending action or an ascending action. In addition, as an opportunity for the driving motor 1031 to start driving, for example, it can be listed that the sealing part 1004 is in a state of moving from the first position to the second position, and only stays at the second position for a predetermined time (for example, 0.5 seconds to 5 seconds). In addition, the above is an example, and it can also be set as other structures to become the start and the opportunity to start the action.

According to the sealing device of this embodiment, the user places the container on the holding portion and places the cover on the container, and the positioning is performed using the positioning member. Furthermore, the user pulls the handle 1029 of the upper cover body 1027 to the front, and the sealing portion 1004 located at the first position moves to the second position. If the sealing portion 1004 that has reached the second position detects that it has stayed at the position for a predetermined time by, for example, a sensor member or a limit switch, the driving motor 1031 starts to drive. If the driving motor 1031 starts to drive, then the transmission mechanism 1032 starts to operate, and then the heater 1013 starts to descend. Next, the heater body 1015 of the heater 1013 starts to squeeze while heating the cover and the container. Whether the heater body 1015 reaches a position where the lid can be squeezed can be applied by any method such as detecting the position by the rotation amount of the driving motor or by limiting the switch. Moreover, if it is detected that a predetermined time (for example, 2 to 5 seconds) has passed since the start of squeezing, the driving motor 1031 rotates in the opposite direction to the previous rotation to raise the heater body 1015. Moreover, the container with the lid is in the following state: if the user takes the handle 1029 in his hand and presses it deeply, the container with the lid can be taken out. Then, the user takes the container with the lid in his hand and serves it for eating.

As described above, according to the sealing device of this embodiment, the user only needs to grasp the handle and pull it and return it to its original position, so the lid can be connected to the container with a very simple operation. In addition, in the sealing device of this embodiment, the same effect as that of the sealing device of the previous embodiment can be obtained. In addition, since the sealing device of this embodiment is configured such that the sealing part 1004 slides on the retaining part 1003, the retaining part 1003 that retains the container in a state of storing contents can be kept from moving. Therefore, according to the sealing device of this embodiment, when the retaining part (and the container retained by the retaining part) is located close to the sealing part 1004, the container is easily skewed.

In addition, the sealing device 1001 of this embodiment can also use the storage part 1006 shown in Figure 23. Figure 23 is a modified example of the second embodiment of the sealing device 1001 of this invention. The storage part 1006 of the sealing device 1001 is also shown in Figures 25 to 27, including: an active roller 2001, a driven roller 2002, and a connecting member 2003 connecting the active roller 2001 and the driven roller 2002. The storage part 1006 includes: a collection L1 of cover bodies L in the storage space, an active roller 2001 and a driven roller 2002 disposed below the collection L1 of cover bodies L, and a connecting member 2003 connecting the active roller 2001 and the driven roller 2002. If the cover body L is to be pulled out, the driving roller 2001 starts to rotate as the cover body L moves because the cover body L is in close contact with the active roller 2001. Moreover, the rotation of the active roller 2001 is also transmitted to the driven roller 2002 through the connecting member 2003. If the cover L is pulled out to a certain extent, the driven roller 2002 that transmits the force from the active roller 2001 will contact the cover L that is pulled out next. Then, the next cover L will be in a standby state at a position where only the front part protrudes. Therefore, it is easy for the user to take out the covers one by one, and the removal operability is greatly improved.

Next, the third embodiment of the sealing device of the present invention is described based on Figures 10 to 13. The sealing device 1001 of this embodiment includes: a housing 1002, a holding portion 1003, a sealing portion 1004, and an operating portion 1005. In addition, regarding the sealing device 1001, a storage portion for storing a large number of lids can also be provided on the upper surface of the housing 1002, but it is omitted here. In addition, in the sealing device 1001 of this embodiment, the structure of the holding member 1 constituting the holding portion 1003 and the structure of the operating panel 1030 constituting the operating portion 1005 are the same as those previously described, so the description here is omitted. The housing 1002 has a storage space 1011 for storing various control parts 1033 constituting the holding part 1003, the sealing part 1004, and the operating part 1005 in the sealing device 1001. In addition, the housing 1002 of the present embodiment is constructed as follows: one end of the upper cover body 1027 is connected to the back panel on the back side by a hinge and other parts, and can be opened at the back side by the hinge. In addition, the sealing device 1001 of the present embodiment is constructed as follows: the sealing part 1004 is constructed as a unitized module, and only the sealing part 1004 can be replaced. By constructing in the above manner, for example, in the maintenance or failure response of the sealing device, it is sufficient to only replace the unitized module of the sealing part 1004, thereby greatly promoting the efficiency of the operation.

Furthermore, the sealing device 1001 of the present embodiment has an insertion portion for inserting the cover. The insertion portion 1034 has an insertion port, and a driving roller and a driven roller are provided behind the insertion port. The driving roller is connected to the rotating shaft of the motor and is configured to rotate by the rotation of the motor. Furthermore, the driven roller is provided in a manner that the circumferential surface contacts the circumferential surface of the driving roller, and is configured in a manner that when the driving roller rotates, it is subjected to the rotational force of the driving roller and rotates. If the user inserts the cover into the insertion portion 1034, the insertion of the cover is detected by, for example, a sensor component. According to the detection result obtained by the sensor component, the motor starts to rotate the rotating shaft, and then the driving roller and the driven roller also start to rotate. At this time, the cover body inserted by the user into the insertion port is configured such that if the front end is close to the part that contacts the driving roller and the driven roller, it is taken into the housing through the driving roller and the driven roller.

Since the structure of the driving motor 1031 and the transmission mechanism 1032 for transmitting the driving force of the driving motor 1031 to the heater body 1015 of the sealing part 1004 is the same as that described above, the description here is omitted. In addition, the sealing part 1004 is provided with a positioning member 1035, which is different from the aspect described above. The positioning member 1035 is provided in a manner such as being located at four positions of the heater body 1015, such as the front, back, left, and right. In addition, the four positioning members 1035 are formed as follows: for example, the positioning members 1035 located in the left and right directions are located at predetermined positions at a short distance from each other by means of a spring member or the like. The distance between the two is preferably smaller than the diameter of the cover. Furthermore, by configuring in the above manner, when the cover inserted from the insertion portion 1034 is transported, it is preferred to configure in a manner that the spacing between the positioning members expands and contracts following the outer shape of the cover. In addition, the positioning member 1035 can also be formed using, for example, a metal material. In addition to the metal material, a heat-resistant resin material or a flexible resin material can also be used. In addition, when a metal material is used as the raw material of the positioning member 1035, it is preferred to pre-wrap a member formed of, for example, a resin material on the positioning member 1035 located on the inner side. By constructing in the above manner, when the cover body inserted from the insertion portion 1034 abuts against the positioning member 1035 on the inner side, the concern about the cover body bouncing back due to the impact of the abutment can be reduced, and the reduction in positioning accuracy caused by this can be prevented.

In addition, although not shown in the figure, a heat-resistant sheet is pre-arranged between the heater body 1015 and the cover. When the heater body 1015 is pressed against the cover, the sheet can always be interposed. As described above, when the cover is heated and joined, dust that may be generated from the surface of the cover can be prevented from adhering to the surface of the heater body 1015 facing the cover. In addition, depending on the cover, there is also a concern that the cover will adhere to the surface of the heater body due to the heat applied from the heater body 1015. By having the sheet interposed as described above, the concern of adhesion can also be eliminated.

The holding part 1003 is provided with a support part 1036 for supporting the bottom of the container. The support part 1036 is configured as follows: when the holding member 1 is stored in the housing 1002, the upward and downward movement is also performed in conjunction. That is, a slope part 1037 is provided on the inner surface of the right side plate of the housing 1002, and the protrusion of the support part 1036 passes through the groove 1038 formed on the slope part 1037, so that the support part can also move in the upward and downward direction as the holding part 1003 moves in the forward and backward direction. The support portion 1036 operates in the following manner: when the retaining member 1 is located outside the housing 1002, it is located at a high position close to the retaining member 1, and as the retaining member 1 moves inside the housing 1002, the height position decreases in sequence, and when the retaining member is located inside the housing 1002, it is located at the lowest end.

If the sealing device of this embodiment inserts a container into the penetration portion of the holding portion, the sensor member arranged on the support portion detects and starts to operate. The operation is first to introduce the holding portion into the shell. At this time, the support portion moves from the relative upper position to the lower position by the slope portion, and the holding portion is introduced into the shell 1002. Then, if the user inserts the cover into the insertion port, the motor of the insertion port starts to drive, and the cover is introduced into the shell by the rotation of the driving roller and the driven roller. The cover is arranged in a state where it is positioned at a predetermined position on the container by the positioning member. Then, the heater body 1015 descends, and the cover is joined to the container by heat sealing. Then, the heater body 1015 rises, and the holding part is squeezed out from the inside of the shell. At this time, the support part rises from the relatively lower position to the upper position along the slope, in the opposite direction of just now. As a result, the container supported by the support part at the bottom also rises, and becomes a state that the user can easily take in his hand.

FIG. 14 shows a variation of the retaining portion 1003. The retaining portion 1003 can be applied to the sealing device of the previously described implementation method. The retaining portion 1003 is used when the diameter (size) of the container is constant. In this case, the user places the cover on the container to position it. At this time, according to the retaining portion 1003 of the variation, positioning portions are provided at 4 locations around the opening where the container is inserted, so that the cover can be positioned simply and its positioning accuracy can also be improved. In addition, the number, shape, and size of the positioning portions are arbitrary and are not limited to this.

Next, a modification of the sealing device 1001 of the second embodiment and a modification of the sealing device 1001 of the third embodiment are described.

The sealing device of the present invention has been described above. The above is only an example of the sealing device of the present invention and is not limited thereto. Therefore, appropriate changes can be made within the scope of the present invention.
