Description

  The present invention relates to various useful fluid products ranging from liquids to viscous fluids, especially beverages, sauces, seasonings, liquid waxes, silicones, shampoos, shaving foams, and other daily or daily use fluids. The present invention relates to a container for filling the contents and taking them out when desired.

  Such containers are known in the form of two- or three-part aerosol cans, and the product contents packed in the cans are at relatively high pressure. These containers have a dome-shaped curved lid, and this lid is provided with an opening that can be opened and closed by an outlet valve. Generally, the outlet valve is fixed to the opening of the lid by caulking with a molded part, a metal disc valve body and a seal ring.

  By the way, many useful fluid products can be stored and taken out from the container without applying a very high pressure. For these fluid products, conventional aerosol cans are costly with an overly complex configuration in terms of manufacturing, material costs, and filling difficulties.

  The object of the present invention is not only to manufacture and fill and close the fluid product contents very easily and in a short time and at low cost, but also allows the filled fluid product contents to be removed easily and under control. In addition, it is an object of the present invention to provide a container that can reliably reclose the fluid product contents remaining after each extraction operation in a sealed state.

This object is achieved according to the invention by a container with the features as claimed in claim 1. This container is preferably in the form of a beverage can by tension molding from a metal sheet according to claim 2, wherein the container body comprises a seamless peripheral wall and a bottom integrally formed therewith, the container body According to common practice in beverage cans, a separate valve lid can be folded and crushed at the outer edge and sealed and secured by a seam.
Such a container (container main body) can be manufactured very easily in a short time and at a low cost like a general beverage can, and since the container main body has a large filling opening, the fluid product contents Correspondingly, filling can be done easily and quickly (can filling).
Such a container in the form of a beverage can manufactured from a metal sheet such as a steel plate or an aluminum plate is pressure resistant and is optimal for customer demands in the food field.
The valved lid can be coupled to the periphery of the filling opening of the container body in a general manner after filling the contents into the container body. Such a container is effective in saving materials from the manufacturing process and filling process to the closing process, and is inexpensive and easy to handle.

  The present invention further includes a valved lid in the form of individual assembly unit parts (Claims 5 and 10), which can be used for containers other than those manufactured in the form of beverage cans. It is also particularly suitable for cans. An outlet valve can be inserted into a fixed state and a sealed state only through a bush or sleeve-shaped molded part into a round lid opening provided in a substantially flat face plate of the lid with valve.

  The sleeve-shaped molded part has a hollow cylindrical shape, and the valve member inserted therein can be moved relative to the molded part by the shape stretchability of the molded part itself (Claim 4). The molded part (attachment member to the lid) and the valve member (held by the molded part) constitute an outlet valve. The valve member is movable in the molded part because the molded part has shape stretchability. In this case, the valve member can be moved relative to the molded part (or relative to the panel surface of the lid), but it can be moved relatively simply by axial sliding or circumferential rotation, such as a roller bearing. In addition, the valve member can be relatively moved with elastic deformation of the molded part while the valve member is held in a sealed state by the molded part. This is a relative movement of the valve member with respect to the molded part, but is a relative movement accompanied by elastic deformation of the molded part having shape stretchability (claims 10 and 11). When the valve member is moved only in the axial direction, the molded part is subjected to symmetrical deformation, that is, compression deformation that is uniform all around the axial direction (claim 19).

  The elastic deformation of the molded part occurs in an upper region of the molded part, that is, a portion located above the annular collar part surrounding the periphery of the lid opening (Claim 19).

  The shape stretchability of the molded part, in other words, the elastic stretchable material constituting the molded part itself has different effects on various parts of the molded part. Preferably, the portion of the molded part located above the annular collar portion of the lid opening performs a spring action, and the portion located below the annular collar portion of the lid opening has a sealing action (a lip projecting in the radial direction). (Depending on the heel part).

  This spring action is preferably used when axial pressure acts on the valve member (claim 11). In this case, the holding action by the lip-shaped flange of the molded part against the annular collar part surrounding the periphery of the lid opening is such that the molded part does not withstand the axial pressure transmitted to it and separate from the lid opening. Therefore, to this extent, the molded part remains connected to the lid opening in a “fixed state and a sealed state”. Nevertheless, at least the upper region of the molded part located above the annular collar is elastic in shape so that a spring action allowing the relative movement of the valve member can occur.

  When the outlet valve is opened, the flow path can be guided through at least one radial through-hole provided in the bottomed cylindrical valve member, and these through-holes are a limited part of the circumference of the valve member. And opens at least one flow path through the at least one through-hole through the inside of the valve member according to the relative position of the valve member with respect to the molded part.

  According to a preferred embodiment of the present invention, such a through hole is provided in the vicinity of one end portion of the valve member, particularly at a position immediately above the lower flange that functions as a disc valve body of the valve member (claim). Item 18). In this case, the lower flange of the valve member functions as a disc valve body, and the outlet valve is opened when the disc valve body is separated from the opening end face of the corresponding sealing lip flange of the molded part. become.

  Assuming that the cause of the symmetrical deformation of the upper part of the molded part is the relative movement of the valve member in the axial direction, the asymmetrical elastic deformation of the upper part is caused by the valve member relative to the molded part. It is a relative tilting motion that can be called tilting. In this case, the deformation of the molded part is uneven at each position in the circumferential direction, and compression deformation occurs on one side according to the direction of the inclination, and no compression deformation occurs on the other side, but only the inclination changes. The sealed contact with the valve member is not lost (claim 19).

  It is also possible to relatively rotate the valve member inside the molded part between these two forms of relative movement, i.e. between the relative movement in the axial direction and the tilting movement. For example, it is possible to act simultaneously with the relative movement in the axial direction. Rotational motion can also be used as an operation to cause axial relative movement of the valve member. In this case, a thread is provided on the inner peripheral surface of the lower region of the molded part, and the valve member is provided on this thread. What is necessary is just to screw the thread provided in the outer peripheral surface.

  When the tilting motion of the valve member is used for opening and closing the outlet valve, it is preferable to provide a plurality of radial through holes at intervals in the circumferential direction of the valve member. Accordingly, at least a part of the plurality of through-holes distributed in the circumferential direction in the valve member is opened at least partly according to the direction of the tilting motion, and the disc valve body has a sealing lip shape at the opening location. The flow path of the outlet valve is opened by separating from the opening end surface of the collar (the lowermost edge of the molded part).

  On the inner peripheral surface of the upper region of the molded part, one or a plurality of grooves extending in the circumferential direction can be formed as recesses that perform a function of determining a required bending position. May support the spring function of the upper region. By providing a groove for adjusting and supporting the spring function of the upper region in this way, a hollow cylindrical molded part is applied when an axial load is applied to the upper end surface of the molded part via the valve member. A definite elastic deformation occurs in the upper region of, and for example, a spring function portion having a shape like a two-stage annular projection continuous in the axial direction of the molded part is formed (when the axial pressure acts) .

  The features and advantages of the present invention will be described in detail in conjunction with the preferred embodiments shown in the drawings as follows.

  The illustrated embodiment is a container in the form of a typical beverage can. The container body 1 is formed as a single piece having a bottom 2 integrally formed by tensile forming a steel plate or an aluminum plate, and is slightly squeezed inward in the vicinity of the upper opening 4 for filling (forming a neck). is doing). The diameter d4 of the opening for filling is slightly smaller than the inner diameter d5 of the container body 1 that forms the internal space 5.

  The valve-equipped lid 8 made up of a substantially flat face plate 3 (= panel) is provided with a general annular impact buffering bead 8b immediately inside the outermost folding edge 8a. Is connected to the flange-like peripheral edge 6 of the filling opening of the main body 1 in a sealed state and a fixed state by a fold-down crushing seam 6a. In FIG. 1, the folding edge of the lid and the flange-shaped peripheral edge of the container body are shown in a state where they have already been folded and seam processed.

  As is apparent from FIG. 2, the valve-equipped lid 8 has a circular lid opening 9 substantially at the center of the face plate, and this lid opening is outward in the axial direction, that is, an annular collar protruding upward. A boundary is defined by the portion 9a. A bottomed cylindrical valve member 12 constituting the outlet valve 10 is coupled to the annular collar portion in a sealed state and a fixed state only by a hollow cylindrical molded part 11 made of a stretchable material. This fixed connection is brought about by elastic deformation of the molded part that tightly sandwiches the upper and lower opening end faces of the annular collar portion. The molded part 11 and the valve member 12 constitute an outlet valve. The outlet valve opens when the valve member is operated, and closes when the operation force disappears. This is possible, as is generally done in some sort of “valve device”, or just an on-off valve. FIG. 2c shows the shut-off state of the outlet valve (closed in the sealed state). When the outlet valve is opened from this state, the flow path for the contents of useful fluid products ranging from liquids for daily use or daily use or foods to viscous fluids is opened. This flow path allows the inside and outside of the container to communicate with each other through the inside 12 i of the bottomed cylindrical valve member 12.

  The molded part 11 made of a stretchable material is connected to the upper and lower edges of the annular collar portion 9a in a fixed state and a sealed state. For this purpose, the molded part 11 having a hollow cylindrical shape, particularly in the form of a sleeve, is provided with a lip-shaped flange portion projecting radially outward with an axial distance h9a corresponding to the height dimension of the annular collar portion. Upper and lower annular holding portions 11a and 11b are integrally formed. The annular holding portion composed of the upper and lower lip-shaped flanges sandwiches the upper and lower end edges of the annular collar portion 9a defining the opening periphery of the lid opening portion 9 from above and below in a sealed state. Here, the lower lip-shaped flange portion 11a has a radially outward projecting dimension larger than that of the upper lip-shaped flange portion.

  The bottomed cylindrical valve member 12 which is a part of the outlet valve 10 can be inserted and disposed without play in the hollow cylindrical shaped molded part 11, and the valve member is spaced apart in the axial direction. The upper and lower flanges extending in the radial direction are integrally provided, and the upper and lower flanges cover the upper end surface and the lower end surface of the molded part, so that the valve member is held in a sealed state by the upper and lower flange portions. ing. In the example shown in the figure, the lower collar part is indicated by 10a, and the upper collar part is indicated by 10b. The lower flange portion functionally constitutes a disc valve body, and is seated on the lower opening edge of the molded part (lower edge of the lower lip-shaped flange portion 11a) to close the flow path or to be separated therefrom. It works to open the flow path.

  With respect to the radial overhanging dimensions of these individual flanges, for example, the outlet valve 10 can be assembled by first mounting the molded part 11 in the lid opening 9 and then mounting the valve member 12 inside the molded part. In order to assemble the outlet valves in the order of installation or in the reverse order, the dimensions are preliminarily aligned with each other. It is also possible to completely assemble the outlet valve 10 first, and to mount the assembled molded part 11 and the valve member 12 together in the lid opening 9. In this case, the molded part 11 and the valve member 12 together form an outlet valve (valve unit) 10.

  The valved lid manufactured in advance and assembled in the unit in this manner is filled with a fluid product into the container from the opening 4 for filling which is largely opened in the container body, and then folded into the peripheral edge 6 of the container body to be crushed seam 6a. It is fixedly arranged.

  The main advantages achieved with such a configuration have already been described in detail at the beginning of this specification, but it should be further clarified that this valve lid is a typical form of beverage can. Can be used for two-part containers of different forms, and if necessary, the central lid opening can be used as an opening for filling the contents before the outlet valve 10 is mounted by the molded part 11. .

  However, it goes without saying that a combination of a container and a lid with a valve according to the illustrated embodiment is suitable.

  The outlet valve 10 itself also has a final filling opening (especially the valve of the outlet valve) after the lidded unit with the valve (prefabricated and assembled) is mounted on the container body (for example by “sown”). It can be used as a flow path through the member internal space 12i. In this case, the mounting is performed by folding the unit around the peripheral edge of the opening of the container body and fixing the unit by jointing. This can be accomplished by shaping the anchoring edge into a double fold shape, for example. In this way, after forming a ridged joint at the folding seam 6a, various fluid products ranging from liquids to viscous fluids, particularly beverages (foods), are filled in a container that has already been closed with a lid with a valve. Is possible.

  Another manner of filling the container is possible, in which case the required fluid contents are pre-filled in the container body prior to mounting the valve lid unit and then the valve lid is mounted and closed. Further, different or similar fluid contents are replenished into the container body via the outlet valve 10.

  Such filling variants are only mentioned in particular with respect to the filling manner mentioned at the outset, and as such do not limit the construction of the container or valve lid according to the invention, but rather the user. It is only useful for explaining usage and application examples on the side.

  With reference to FIG. 2a and FIG. 2b, the basic operation | movement form of the outlet valve (valve structure) in the state integrated in the lid | cover as shown in FIG. 2c is demonstrated below. The operation of the outlet valve in this case can be understood with reference to FIGS. 3a to 3c. FIG. 3a shows a state in which the valve member 12 opens the flow path in the outlet valve shown in FIG. 2c. In this state, the flow path is opened by a downward force acting on the valve member 12 in the axial direction. In this case, the valve member moves downward in the direction indicated by the arrow S, and thereby the disk. The radial through-hole 30 opens into the container body at a position directly above the lower flange portion 10a constituting the valve body, and thus the flow path leading to the closed space of the container through the internal space 12i of the valve member 12 is opened. In this manner, the fluid content can be taken out from the inside of the container (only the upper end portion is shown). When the valve member 12 moves downward in the axial direction, the upper region 11c of the molded part 11 is mainly compressed and deformed. In FIG. 3a, compression deformation of the upper region 11c of the molded part 11 is applied to an upper part of the annular collar portion 9a provided on the lid face plate 3 made of a metal sheet (above the upper edge of the lid opening 9 in FIG. 2b). As a result, a two-stage annular projection that is continuous in the axial direction is formed. Conventionally, such an annular protrusion is not formed, and the molded part is purely cylindrical between the upper and lower flanges 10a and 11b in FIG. 2c.

  Such compressive deformation can be achieved by configuring the molded part 11, particularly the upper region, with a shape-stretchable elastic material. In other words, the molded part has a spring function in the region above the annular collar portion 9a when the shape stretchable material is compressed and deformed. This spring function opposes the force in the direction of opening of the outlet valve 10, and when this pressure disappears, the valve member 12 is returned upward in the direction indicated by the arrow S, thereby closing the through hole 30. The flow path is again cut off.

  The lower end portion of the molded part 11 is a widely projecting lower lip-shaped flange 11a, whereby the molded part itself is in close contact with the periphery of the lower opening of the lid opening in a sealed state. The lower opening end surface 11a ′ of the flange portion is a valve seat surface that faces the lower flange portion 10a of the valve member 12 and is in close contact with the sealed state, and when the lower flange portion 10a of the valve member 12 is seated. The flow path of the outlet valve is shut off, and when the seat is separated, the flow path is opened.

  FIG. 3b shows how the outlet valve is opened and closed in another manner, and the movement component when the valve member is opened and closed by turning is indicated by a spiral arrow R. FIG. In this embodiment, the circumferential wall of the valve member 12 is provided with two radial through holes 31 and 32 in the vicinity of the lower end with a gap in the circumferential direction, and each of these through holes serves as an outlet valve. Contributes to opening and closing each channel. The rotational movement for opening and closing the outlet valve may be additionally performed by superimposing the movement component S in the axial direction, but this is not always essential and is merely allowed. The rotation operation is performed by the user.

  Although not shown in the drawings, in still another embodiment, a short screw is provided on the inner peripheral surface of the molded part 11 in the region above the lower lip flange 11a and below the upper end surface of the annular collar portion 9a of the lid opening. A thread is provided, and a thread provided corresponding to the outer peripheral surface of the valve member 12 is screwed into the thread. Thus, when the valve member 12 is rotated, the valve member is forcibly moved in the axial direction by screwing of the threads. Also in this case, the upper region 11c of the molded part is compressed by undergoing elastic deformation having symmetry in the axial direction. In order to achieve this, it is important to form the molded part 11 with a shape stretchable material.

  FIG. 3c shows a state where the outlet valve is opened and closed by a tilting operation. In this case, asymmetric deformation occurs in the molded part 11. In FIG. 3c, the left side portion of the molded part 11 is more compressively deformed than in the case shown in FIG. 3b. On the other hand, in the right part, the upper region 11c of the molded part 11 is drawn inward in the radial direction following the tilting, but this is still within a range where the sealing function is not lost. Due to the inclination angle of the inclination movement T indicated by the arrow T, the contact of the upper lip-shaped flange portion 11b with the annular collar portion 9a of the lid opening is slightly opened. As a result, at least a part of the radial through-hole is opened, but in the illustrated example, among the four through-holes provided at the lower end portion of the valve member 12, the through-hole 33 is entirely opened and the through-hole 30 (through-hole Facing the mouth 32) is partially opened, and the through-hole 31 is not opened.

  In order to improve the function by reducing the fluid resistance of the flow path when the valve is opened, the inner diameter in the lower region of the molded part 11 shown in FIG. 2a may be slightly expanded as shown in FIG. 3a. The portion above the enlarged diameter portion is a sealing region and is in close contact with the outer periphery of the valve member. Above that, a required bending position region as described later continues to the upper end of the upper region 11 c of the molded part 11.

  As described above, the symmetrical compression deformation shown in FIGS. 3a and 3b and the asymmetric compression deformation shown in FIG. 3c are caused by the shape stretchability of the molded part 11 to be called a coupling part or a compensation part. It is clear that the valve member 12 is generated or formed by relatively different movements relative to at least the upper region 11c. Such a molded part functions as a kind of flexible fixture that holds the valve member 12 so as to be relatively movable with respect to the lid 8 and the face plate portion in the closed state.

  The shape stretchability of the molded part, particularly in the upper region, can be configured in various degrees. For example, regarding the return spring force at the time of the compression deformation described above, the valve member 12 is substantially axially driven by the operating force. If the operating force disappears after being pushed into the molded part along the line, it can be configured to automatically return to the stable position, which is the original closed position. With respect to the frictional resistance between the outer peripheral surface of the valve member 12 and the inner peripheral surface of the molded part 11, even if it is a cylindrical sealing surface, only a slight frictional resistance is generated, that is, the compression-deformed upper part. It is possible to make it relatively compatible with the shape stretchability of the molded part so that only a slight frictional resistance that overcomes the return spring force in the region 11c is overcome.

  The molded part 11 should also be referred to as a sleeve-shaped molded part and can therefore be referred to simply as “sleeve”. The sleeve is formed into a hollow cylindrical shape corresponding to the shape of the hollow cylindrical valve member 12. The molded part 11 is inserted into the lid opening 9 in a fixed state and a sealed state. This is referred to as “adhesion”, which means that the sleeve can be held at the lid opening to achieve an assembly that can withstand the force acting on the valve member 12. The valve member 12 is moved relative to the sleeve 11 and is displaced with a relative movement component in the axial direction as described above. Such relative movement is caused by the shape stretchability of the molded part 11, particularly by the shape stretchability of the upper region 11 c during rotational and non-rotating straight motions that cause symmetrical compression deformation, and is also shown in FIG. In the case of such an inclined movement, it is additionally generated by utilizing the shape stretchability of the lower lip-shaped flange portion 11a.

  By inserting a hollow cylindrical valve member into the molded part 11 without any gap, sealing between the two is achieved. At least one sealing line is formed between the two, which is preferably a complete circumferential cylindrical sealing zone, whereby the through-hole 31 when the outlet valve 10 is in the closed position. , 32, 33, 30 can be closed together with a sufficient sealing function.

  The bottomed cylindrical molded part 12 has an upper flange part 10b and a lower flange part 10a that cover both end faces in the axial direction of the molded part 11, but the valve member is in the axial direction with respect to the molded part. The relative movement is possible, and as a matter of course, a part of the movement component in the axial direction is transmitted to the molded part 11 in particular from the upper flange part, and elastic deformation thereof occurs. However, with respect to the face plate 3 of the lid 8, the molded part 11 is held by the annular collar portion 9a.

  These upper and lower flanges projecting from the outer peripheral surface of the molded part only need to extend over at least part of the circumferential direction, but preferably both flanges 10b and 10a are extended over the entire circumference. In this case, the lower flange portion 10a forms the original valve edge of the disc valve body at the lower end of the outlet valve 10 inside the container body.

  The upper and lower flanges 11b and 11a formed integrally with the molded part as an annular holding part project from the outer peripheral surface of the molded part in a lip shape, and sandwich the annular collar part 9a of the cover face plate 3 from above and below to form the molded part. The lid opening 9 is held in a fixed state and a sealed state. In particular, the lower lip-shaped flange portion 11a is in close contact with the inner surface of the lid surface plate 3 at the periphery of the opening of the lid opening 9 in the container and performs a sealing function over the entire circumference.

  In this case, the lid opening 9 is a circular opening that matches the both valve parts of the outlet valve, that is, the cylindrical shape of the molded part 11 and the valve member 12, and is preferably provided at the center position of the lid face plate.

  FIG. 4 shows a more detailed embodiment of the basic configuration of FIG. 2c. The parts assembled in FIG. 4 are shown in more detail in exploded views in FIGS. 5a to 5c, which correspond to the schematic views 2b and 2a, but are shown generally in FIG. 2b. The lid 8 with the lid opening 9 is shown partially in FIG. 5a (omitting the folding edge 8a).

  The first valve part (A) shown in FIG. 5c and the second valve part (B) shown in FIG. 5b are arranged in the order of arrows A and B from the lower surface side of the lid face plate as shown in FIG. 5a. 9 is pushed into. Alternatively, the valve assembly A + B (as shown in FIG. 2a) in which both valve components are assembled together and pushed together may be pushed into the lid opening 9 from the lower surface side of the lid surface plate. The first valve part A is a molded part 11, and an annular collar part 9a of a metal lid is snap-fitted between the upper and lower lip-shaped flange parts 11b and 11a projecting from the outer peripheral surface thereof. A cylindrical upper region 11c integrally extends as an effective compression spring element above the upper lip-shaped flange portion 11b, and the upper end surface of the upper region has a valve member 12 as a second valve component. The upper collar part 10b is covered.

  The lower flange portion 10a of the second valve part forms a closed bottom surface of the bottomed cylindrical valve member 12, and constitutes a disc valve body projecting radially outward. In this embodiment, the valve parts A and B are the molded part 11 and the valve member 12 as described above, but the valve member 12 has at least one radial through hole, preferably three or four diameters spaced in the circumferential direction. Directional through holes 30 to 33 are provided.

  One or more groove | channels 40 extended in the circumferential direction are provided in the inner peripheral surface of the upper area | region 11c which functions as a compression spring element in a molded component as a recessed part which performs the function which determines the bending position at the time of a compressive deformation. . This groove changes the compression deformation resistance in the upper region 11c of the molded part 11 to adjust and support its spring function. This groove 40 is also shown in FIG. 4, so that it is clear where the groove is located with the assembled valve structure in the valve closed position. Similarly, in FIG. 2 c, reference numeral 40 indicates the position of the groove in the molded part 11.

  The final assembled state, that is, the valved lid shown in FIG. 4 (the folding edge is omitted) is sealed with a ridge joint at the opening edge of the beverage can at the folding edge that actually exists FIG. 6 shows a state of being attached to FIG. 6, which is slightly enlarged in size as compared with FIG. 1, and more accurately reproduces the shape and arrangement of each part.

  In FIG. 6, the flow path formed by the outlet valve is indicated by the symbol F, and this flow path is closed when the through hole 30 of the valve member is in the closed position with respect to the molded part 11. When the valve member 12 that has closed the flow path is pushed relative to the molded part, the flow path that passes through the internal space 12i of the valve member 12 passes through the through hole. The flow path opened in this way can be used for both the extraction of the fluid from the container internal space 5 and the filling of the fluid into the internal space 5.

  The lid by the folding seam 6a at the peripheral edge 6 of the filling opening of the container body can be either before or after the container body 1 is filled with the contents. When the container body is already folded and crushed and closed with the joint 6a, the flow path F formed with the outlet valve opened can be used for replenishment or replenishment of the contents. However, the original filling which is not replenishment is preferably performed on the container main body in a state where the can is filled, that is, the lid is not closed with the lid with the valve by the folding seam 6a.

The object of the present invention is not only to manufacture and fill and close the fluid product contents very easily and in a short time and at low cost, but also allows the filled fluid product contents to be removed easily and under control. Furthermore, it is an object of the present invention to provide a valve-equipped lid and a container that can reliably reclose the fluid product contents remaining after each take-out operation in a sealed state.

This object is achieved according to the invention by a valved lid having the features as claimed in claim 1.

The valved lid according to the present invention can be in the form of individual assembly unit parts, which can be used for containers other than those manufactured in the form of beverage cans. Is also particularly suitable. An outlet valve can be inserted into the fixed state and the sealed state only through a bush or sleeve-shaped molded part into the round lid opening provided in the face plate of the lid with valve.

The sleeve-shaped molded part has a hollow cylindrical shape (Claim 2) , and the valve member inserted therein can be relatively moved in the molded part by the shape stretchability of the molded part itself . The molded part (attachment member to the lid) and the valve member (held by the molded part) constitute an outlet valve (Claim 5 ). The valve member is movable in the molded part when the molded part has shape stretchability . In this case, the valve member can be moved relative to the molded part (or relative to the panel surface of the lid), but it can be moved relatively simply by axial sliding or weekly public rotation such as a roller bearing. In addition, the valve member can be relatively moved with elastic deformation of the molded part while the valve member is held in a sealed state by the molded part. This is a relative movement of the valve member with respect to the molded part, but is a relative movement accompanied by elastic deformation of the molded part having shape stretchability (claims 5 and 6 ). Moving the valve member only in the axial direction, the molded part is deformed symmetry, i.e., will experience all around uniform compressive deformation along the axial direction (claim 14).

The elastic deformation of the molded part occurs in an upper region of the molded part, that is, a portion located above the annular collar part surrounding the periphery of the lid opening (claim 14 ).

This spring action is preferably used when axial pressure acts on the valve member (claim 7 ). In this case, the holding action by the lip-shaped flange of the molded part against the annular collar part surrounding the periphery of the lid opening is such that the molded part does not withstand the axial pressure transmitted to it and separate from the lid opening. Therefore, to this extent, the molded part remains connected to the lid opening in a “fixed state and a sealed state”. Nevertheless, at least the upper region of the molded part located above the annular collar is elastic in shape so that a spring action allowing the relative movement of the valve member can occur.

According to a preferred embodiment of the present invention, such a through hole is provided in the vicinity of one end portion of the valve member, particularly at a position immediately above the lower flange that functions as a disc valve body of the valve member (claim). Item 13 ). In this case, the lower flange of the valve member functions as a disc valve body, and the outlet valve is opened when the disc valve body is separated from the opening end face of the corresponding sealing lip flange of the molded part. become.

Assuming that the cause of the symmetrical deformation of the upper part of the molded part is the relative movement of the valve member in the axial direction, the asymmetrical elastic deformation of the upper part is caused by the valve member relative to the molded part. It is a relative tilting motion that can be called tilting. In this case, the deformation of the molded part is uneven at each position in the circumferential direction, and compression deformation occurs on one side according to the direction of the inclination, and no compression deformation occurs on the other side, but only the inclination changes. The sealed contact with the valve member is not lost (claim 14 ).

When using the tilt movement of the valve member to open and close the outlet valve, it is preferable that at intervals in the circumferential direction of the valve member providing a plurality of radial through opening (claim 13). Accordingly, at least a part of the plurality of through-holes distributed in the circumferential direction in the valve member is opened at least partly according to the direction of the tilting motion, and the disc valve body has a sealing lip shape at the opening location. The flow path of the outlet valve is opened by separating from the opening end surface of the collar (the lowermost edge of the molded part).

On the inner peripheral surface of the upper region of the molded part, one or a plurality of grooves extending in the circumferential direction can be formed as recesses that perform a function of determining a required bending position. May support the spring function of the upper region. By providing a groove for adjusting and supporting the spring function of the upper region in this way, a hollow cylindrical molded part is applied when an axial load is applied to the upper end surface of the molded part via the valve member. A definite elastic deformation occurs in the upper region of, and for example, a spring function portion having a shape like a two-stage annular projection continuous in the axial direction of the molded part is formed (when the axial pressure acts) .
The present invention further provides a container as described in claim 16, which comprises a container body with a seamless peripheral wall in the form of a beverage can and a bottom integrally formed therewith, In accordance with common practice with cans, a separate valved lid can be folded at the outer edge and can be fixedly connected in a sealed state by a seam.
Such a container (container main body) can be manufactured very easily in a short time and at a low cost like a general beverage can, and since the container main body has a large filling opening, the fluid product contents Correspondingly, filling can be done easily and quickly (can filling).
Such a container in the form of a beverage can manufactured from a metal sheet such as a steel plate or an aluminum plate is pressure resistant and is optimal for customer demands in the food field.
The valved lid can be coupled to the periphery of the filling opening of the container body in a general manner after filling the contents into the container body. Such a container is effective in saving materials from the manufacturing process and filling process to the closing process, and is inexpensive and easy to handle. However, the fluid product is introduced into the container before the valve-equipped lid is mounted, and then the same or different fluid product is introduced into the container after being closed with the valve-equipped lid through the outlet valve. It is also possible to do.

The bottomed cylindrical valve member 12 has an upper flange portion 10b and a lower flange portion 10a that cover both end surfaces in the axial direction of the molded part 11, but the valve member is positioned in the axial direction with respect to the molded part. The relative movement is possible, and as a matter of course, a part of the movement component in the axial direction is transmitted to the molded part 11 in particular from the upper flange part, and elastic deformation thereof occurs. However, with respect to the face plate 3 of the lid 8, the molded part 11 is held by the annular collar portion 9a.

By the way, many useful fluid products can be stored and taken out from the container without applying a very high pressure. For these fluid products, conventional aerosol cans are costly with an overly complex configuration in terms of manufacturing, material costs, and filling difficulties.
Patent Document 1 discloses a closure cap for a container containing a flowable product as a content. The cap has a circular opening with an outlet valve disposed therein. The outlet valve includes a sleeve-shaped molded part and a cylindrical valve member, and is inserted into the sealed state and the fixed state only by the molded part. Patent Document 2 shows a metal beverage can comprising a container body and a lid having a closeable outlet opening. This lid can be fixed to the container body with a folded seam. Further, Patent Document 3 shows a conventional aerosol valve having a cylindrical valve member as a valve body and a sleeve-shaped molded part. The molded part is shape-extensible and the valve member is a molded part. The valve can be opened by moving by elastic deformation. This valve is disposed at the center of the cup-shaped lid portion. Further, Patent Literature 4 describes a lid with a valve for an aerosol can, and an outlet valve of the lid has a cylindrical valve member as a valve body and a sleeve-forming part having a shape stretchable. In this case, the valve member can be moved by the elastic deformation of the molded part to open the valve. The outlet valve is disposed at a central position with respect to the cup-shaped valve lid that is joined to the outer peripheral portion of the lid that is folded and crushed and fixed to the container main body by penetration joining (needle driving).
