Description

[Technical Field]

[0001] The present invention relates to a container with a transfer stopper cap, in which the transfer stopper cap is attached to the opening of the container body by plugging, and more particularly to a container with a transfer stopper cap that can prevent the inner plug and screw cap from rotating together. [Background technology]

[0002] A transition stopper cap is known as a food container for storing contents such as dressing. The transition stopper cap seals the inside of the container body with an inner stopper having a transition stopper body until the container is opened, and the transition stopper body can be removed from the inner stopper and held on the screw cap side by rotating a screw cap that is attached by threading onto the inner stopper in the opening direction to open the container.

[0003] However, when a container with a transition stopper cap attached is stored at high temperatures, the mouth of the container body may deform radially outward, causing a decrease in the torque between the mouth of the container body and the inner stopper.When the torque decreases, the inner stopper may rotate together with the screw cap, making it impossible to remove the transition stopper from the inner stopper, and therefore making it impossible to open. In addition, capped containers have also been known in the past that have a structure in which a protrusion on the mouth of the container body is inserted into the inner surface of the outer tube of the inner stopper to prevent the screw cap and inner stopper from rotating together (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 57-37853 Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, if the anti-rotation structure described in Patent Document 1 is adopted in a known transfer stopper cap, it is expected that the screw cap and inner stopper will be prevented from rotating together, making it easier to remove the transfer stopper body of the inner stopper and transfer it to the screw cap side.

[0006] However, in the past, there were transfer stopper caps that required the screw cap to be rotated in the closing direction when opening, and some users would initially rotate the screw cap too hard in the closing direction.In this case, the screw cap and inner stopper would be rotated, and the protrusion on the mouth of the container body would scrape the inner surface of the outer tube of the inner stopper, which could result in the scraped area being widespread. As a result, when the container is rotated in the closing direction and then in the opening direction, the scraped portion impairs the function of preventing co-rotation between the protrusion at the mouth of the container body and the inner surface of the outer tube of the inner stopper, and the transfer stopper body cannot be removed from the inner stopper and transferred to the screw cap side, resulting in the problem of being unable to open the container.

[0007] The present invention aims to solve the above problem and to provide a container with a transfer stopper cap that can be opened by first rotating the screw cap in the closing direction, but then rotating it in the opening direction, preventing the inner stopper from rotating together with the screw cap. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the present invention provides a container with a transition stopper cap, which is attached by screwing a screw cap that is attached to the mouth of a container body by rotating the screw cap that is screwed onto the inside stopper, thereby removing the transition stopper body from the inside stopper and holding it on the screw cap side.The container body has a locking ridge that is attached to the outer periphery of the mouth and prevents the inside stopper from coming out, at least one ridge group region where multiple ridges are formed within a predetermined angular range on the outer periphery of the locking ridge, and an un-locked region where no ridges are formed within the predetermined angular range on the outer periphery of the locking ridge, and the inside stopper has a configuration characterized by having an outer tube whose inner surface is penetrated by the ridges of the container body when the inside stopper is attached, and a locking ridge that protrudes from the lower inner periphery of the outer tube and engages with the lower part of the locking ridge.

[0009] As an embodiment of a container with a transfer stopper cap, the container body is configured to have at least one protrusion formed in the non-protrusion region that is higher than the height of the protrusion, and the outer tube is configured to have a notched recess recessed into the outer surface on the outer periphery above the locking protrusion, and a sorting mechanism below the notched recess that enables the inner stopper to be separated from the container body and disposed of separately, and the protrusion group region is configured to be formed in the range of 60° to 120°, and the non-protrusion region is configured to be formed in the range of 50° to 120°. [Effects of the Invention]

[0010] By adopting the above-described configuration, the container with a transfer stopper cap of the present invention can be opened by rotating the screw cap in the closing direction relative to the container body when opening it, and then rotating it in the opening direction without the inner stopper rotating with it, by reliably rotating the screw cap relative to the inner stopper and removing the transfer stopper body from the inner stopper.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Next, the container with a transfer plug cap of the present invention will be described with reference to the drawings, giving examples. In the following description, the vertical direction in FIG. 1(a) is referred to as the "axial direction," the upward direction as the "upward direction," the downward direction as the "downward direction," and the horizontal direction as the "radial direction."

[0013] Example 1 In FIG. 1, A is a container body, B is an inner plug attached to the container body A by plugging, and C is a screw cap attached to the inner plug B by screwing it on so as to be freely detachable. The container body A is made of a material that has shape retention, and the inside stopper B is made of a material that is softer than the container body A.

[0014] As shown in Figures 1, 2(b) and 3, the container body A has a locking rib 2 protruding from the upper outer periphery of the mouth 1, which fits over the inside plug B and holds it in place to prevent it from slipping out. On the outer periphery of the locking rib 2, a protrusion group region 3a is formed in which a plurality of sharp-tipped protrusions 3 are formed in an arc-shaped angular range, with R-shaped upper ends 3r that hang down axially from the upper end 3r along the outer periphery of the locking rib 2 and protrude radially outward to a height L1, and a non-protrusion region 3b is formed which is an arc-shaped angular range in which no protrusions 3 are formed. In this embodiment, the protrusions 3 are triangular in plan view and protrude to a height L1 of 0.4 mm. As shown in Figure 3(a), a protrusion group region 3a is formed in an arc shape with 21 protrusions 3 at intervals of 6° within a range of 120° centered on the positions of 90° and 270° when viewed from above, and a circular arc-shaped non-protrusion region 3b with no protrusions 3 formed within a range of 60° centered on the positions of 0° and 180° is formed alternately at opposite positions on the circumference.

[0015] As shown in Figures 1, 2 and 4(b), the stopper B is composed of an outer tube 6 on the outer periphery, an inner tube 7 on the inner periphery, and an upper wall 8 located on the top side of the mouth portion 1, and is also composed of an attachment portion 5 which forms an annular groove into which the mouth portion 1 of the container body A fits, a threaded wall portion 9 which stands upright from the attachment portion 5, a top wall 10 which extends inward from the upper end of the inner periphery of the threaded wall portion 9, and a dispensing tube 11 which stands upright from the top surface of the top wall 10. As shown in Figures 1 and 2(b), the mounting portion 5 is mounted to the mouth 1 of the container body A by fitting the inner surface 6a of the outer tube 6 to the outer periphery of the locking protrusion 2 and the protrusion 3 with a tightening margin α, fitting the outer periphery of the inner tube 7 to the inner periphery of the mouth 1, and abutting the lower surface of the upper wall 8 against the upper surface of the mouth 1.

[0016] The inner circumference of the dispensing tube 11 serves as a dispensing outlet that guides the contents contained in the container body A and dispenses them from the tip, and a transition stopper body 13 is integrally connected to the lower end of the inner circumference via a thin-walled weakened portion 12 formed around the entire circumference. The transition plug body 13 comprises a ring-shaped peripheral portion 14 connected to the inner circumference of the thin-walled weakened portion 12, a cylindrical wall 15 formed inside the peripheral portion 14, and a circular central bottom wall 17 that seals the inner side of the lower end of the cylindrical wall 15 and has a columnar protrusion 16 erected in the center.

[0017] The peripheral edge 14 has an annular groove 18 recessed from the underside to a predetermined height, and a first engagement protrusion 19 constituting the first engagement portion is provided around the lower outer periphery, and at the upper outer periphery, at positions 0° and 180° relative to the axis, mating recesses 20 constituting the first mating portion that mating with a second mating portion arranged on the screw cap C described later are cut out from the outer periphery, and between each mating recess 20, a lightening portion 21 formed in an arc shape along the cylindrical wall 15 is recessed from the top surface. In this embodiment, the first fitting portion is embodied as a fitting recess 20 at positions 0° and 180° relative to the axis of the upper outer periphery of the transition plug body 13, but the number and shape of the first fitting portion are not important as long as it has recesses and protrusions in the circumferential direction of the transition plug body 13 that fit with the second fitting portion of the screw cap C.

[0018] The threaded wall portion 9 has a male threaded portion 25 that constitutes the first threaded portion screwed onto its outer surface, and a plurality of reinforcing ribs 26 that are connected to the top wall 10 at their upper portions and extend in the axial direction are arranged on its inner surface. The thread height of the male thread portion 25 is formed lower than the normal thread height. In this embodiment, the male thread portion 25 is a double-start thread, but depending on the height of the threaded wall portion 9, it can be a multiple-start thread having three or more starts.

[0019] As shown in FIG. 2(a), the top wall 10 is provided with a recessed step 27 on the outer periphery side, and a sound-emitting protrusion 28 is disposed on the inner periphery side of the step 27. On the upper surface of the upper wall 8, a plurality of stopper protrusions 29 are arranged at predetermined circumferential intervals to engage with the screw cap C and stop rotation, and each stopper protrusion 29 has an approximately vertical abutment surface in the screwing / unscrewing direction and an inclined surface in the screwing direction.

[0020] As shown in Figure 4(b), the outer tube 6 has a locking protrusion 31 protruding from the lower inner periphery, the upper part of which engages with the lower part of the locking protrusion 2 of the container body A to prevent the mouth part 1 from coming off, and a notched recess 32 is recessed from the outer periphery above the locking protrusion 31, and a separation mechanism F is provided below the notched recess 32 to separate the inner stopper B from the container body A so that it can be disposed of separately. The separating mechanism F has a gripping portion 34 provided via a slit 33 formed in the axial direction over a predetermined arc range on the lower outer peripheral surface of the outer tube 6, and the gripping portion 34 is separated from the outer tube 6 by a thin-walled vertical cut portion 35 so that it can be extended outward.Furthermore, the notched recess 32 can be easily broken, making it easy to remove the inner stopper B from the container body A.

[0021] As shown in Figures 1, 2 and 4(a), screw cap C has a disk-shaped top wall 40 and an outer peripheral wall 41 that hangs down from the outer edge of top wall 40. A sealing cylinder portion 43 and a threaded cylinder portion 44 hang down concentrically from the inside on the inner surface of top wall 40. Furthermore, a sound-emitting member 45 is disposed between sealing cylinder portion 43 and threaded cylinder portion 44 at a position that engages with sound-emitting protrusion 28 on top wall 10 of inside plug B.

[0022] The sealing tube portion 43 is provided on its outer periphery with a sealing portion 47 that abuts against the inner surface of the dispensing tube 11 to seal the spout when the screw cap C is attached to the inner stopper B, and is provided with a second engaging protrusion 48 at the lower end of the inner periphery that constitutes a second engaging portion that fits over the first engaging protrusion 19 on the peripheral portion 14 of the transition stopper body 13, and is provided with mating protrusions 49 at the upper inner periphery that protrude radially inward and constitute a second fitting portion that fits from above into the fitting recesses 20 of the transition stopper body 13, in the same number as the mating recesses 20.

[0023] The threaded tube portion 44 has a female thread portion 50 threaded on its inner circumference, which constitutes a second thread portion that screws into the male thread portion 25 of the center plug B, and a plurality of wedge-shaped recesses 51 that engage with the stopper protrusions 29 are arranged circumferentially on the lower end surface. The female thread portion 50 is formed with a shape and number of threads that allow it to screw into the male thread portion 25, and the thread height of the female thread portion 50 is formed lower than the normal thread height, just like the male thread portion 25, so that when the male thread portion 25 and the female thread portion 50 are screwed together, the engagement between the tips of the threads is set smaller than in the past. The wedge-shaped recess 51 is formed in a shape corresponding to the abutment surface and inclined surface of the stopper protrusion 29, so that when the cap is closed, the lower end surface of the screw tube portion 44 abuts against the upper surface of the upper wall 8 of the mounting portion 5 of the inner plug B, and the abutment surfaces of the wedge-shaped recess 51 and the stopper protrusion 29 abut against each other, completing the tightening of the screw cap C onto the inner plug B.

[0024] As shown in Figures 1(a), 2(a) and 4(a), the sound-producing member 45 is composed of a plate-shaped base 53 that hangs down from the underside of the top wall 40 between the threaded cylindrical portion 44 and the sealed cylindrical portion 43, and a rod-shaped vibrating piece 54 that hangs down from the base 53 and is formed to be elastically deformable. The sound-producing member 45 is set so that just before the screw cap C is completely tightened, the tip of the vibrating arm 54 comes into contact with the sound-producing protrusion 28 of the inner plug B, the tightening proceeds while bending and deforming the vibrating arm 54, and at the same time as the tightening is completed, the vibrating arm 54 moves over the sound-producing protrusion 28 and tries to restore its original shape, thereby vibrating and generating sound.

[0025] Next, the manner of use and the effects of this embodiment will be described. In this embodiment, the transfer stopper cap is made by molding the inner stopper B and the screw cap C separately, then fitting the screw cap C onto the top of the inner stopper B to set it as a transfer stopper cap, and then fitting the attachment portion 5 of the inner stopper B into the mouth 1 of the container body A filled with the contents.

[0026] When setting the screw cap C on the inside plug B, first, the fitting protrusions 49 inside the sealing cylindrical portion 43 of the screw cap C are aligned and fitted from above the respective fitting recesses 20 on the peripheral portion 14 of the transition plug body 13 of the inside plug B, and the screw cap C is then pushed into the inside plug B. From this state, when the screw cap C is pushed into the inner plug B, the inside of the lower peripheral surface of the female thread portion 50 of the threaded cylindrical portion 44 of the screw cap C abuts against the outside of the upper peripheral surface of the male thread portion 25 of the threaded wall portion 9 of the inner plug B, and moves over the threaded cylindrical portion 44 while pushing it outward. As the screw cap C is pushed in further, the female thread portion 50 and the male thread portion 25 mesh over the entire range, the screw tube portion 44 is released from being pushed outward and returns to its original shape, and the second engaging protrusion 48 of the sealing tube portion 43 overcomes and engages with the first engaging protrusion 19 formed on the peripheral portion 14 of the transition stopper body 13 of the inner stopper B, thereby completing the pushing-in process. At the same time, the lower end surface of the threaded cylindrical portion 44 of the screw cap C lightly abuts the upper surface of the upper wall 8 of the inside plug B or comes close to it with a small gap formed, and the wedge-shaped recess 51 of the threaded cylindrical portion 44 fits into the stopper protrusion 29 of the upper wall 8, completing the setting as a transfer plug cap.

[0027] After the transition stopper cap is set, the respective mating protrusions 49 on the inside of the sealing cylinder portion 43 of the screw cap C fit into the respective mating recesses 20 on the peripheral portion 14 of the transition stopper body 13 of the inner stopper B, and further, the second engagement protrusion 48 on the sealing cylinder portion 43 fits into the first engagement protrusion 19 formed on the peripheral portion 14 of the transition stopper body 13 of the inner stopper B, and the transition stopper body 13 is engaged inside the screw cap C. Furthermore, the female thread portion 50 of the threaded cylindrical portion 44 of the screw cap C is engaged with the male thread portion 25 of the threaded wall portion 9 of the inside plug B and screwed into place. In this way, in the transfer plug cap of this embodiment, when the screw cap C is set on the inner plug B, the screw cap C can be attached to the inner plug B by tapping.

[0028] The transfer stopper cap is attached by fitting the attachment portion 5 of the inner stopper B to the mouth portion 1 of the container body A filled with the contents. When attaching the transfer stopper cap set on the mouth 1 of the container body A, first, the inner stopper B is placed over the mouth 1 from above and pushed in, so that the lower part of the locking protrusion 31 at the lower end of the inner circumference of the outer tube 6 of the attachment part 5 first abuts against the upper surface of the locking protrusion 2 of the mouth 1, and then abuts against the R-shaped upper end 3r of the protrusion 3 in the protrusion group region 3a, and the inner stopper B descends into the mouth 1 of the container body A while pushing the outer tube 6 open from below.

[0029] Furthermore, as the transition stopper cap continues to descend, locking projection 31 climbs over locking rib 2 and projection 3, the deformation of outer tube 6 returns to its original state, and as shown in Figures 1 and 2(b), the inner surface 6a of outer tube 6, including projection 3 in projection group region 3a, meshes and engages with the outer periphery of locking rib 2 with a tightening margin α, and the upper part of locking projection 31 of outer tube 6 engages with the lower part of locking rib 2, so that the set transition stopper cap is attached to container body A so that it will not come off, and the stoppering is completed. After the stoppering is completed, the projection group region 3a of the locking projection 2 engages with the inner peripheral surface 6a of the outer cylinder 6 by the amount of interference α of each projection 3, and the non-projection region 3b without projections 3 is attached only by the interference of the outer periphery of the locking projection 2. Here, if the height L1 of the protrusion 3 is set to 1 mm or more, when the container body A is stored with the transfer stopper cap attached to the mouth 1, there is a risk that the thin-walled portion of the sorting mechanism F will break due to the protrusion 3 biting into the outer cylinder 6 of the inner stopper B. For this reason, in this embodiment, it is preferable to set the height L1 of the protrusion 3 in the range of 0.3 to 0.8 mm. In order to prevent unauthorized opening of the transfer stopper cap before use after it has been sealed into the container body A, a shrink label or sealing member, etc., may be provided between the screw cap C and the inner stopper B, although this is not shown.

[0030] When using a container equipped with a transfer stopper cap, the container body A is grasped and fixed, and the screw cap C is rotated to open it. When the user rotates the screw cap C in the opening direction, the locking protrusions 2 of the container body A, particularly the protrusions 3 in the protrusion group region 3a, bite into and engage with the inner surface 6a of the outer tube 6 of the inner stopper B, so that even when the screw cap C is rotated relative to the container body A, the inner stopper B does not rotate together with the screw cap C, and the torque for rotating the screw cap C can be transmitted to the inner stopper B without waste.

[0031] Furthermore, if a user accidentally rotates the screw cap C in the closing direction at first, the user will forcefully rotate the screw cap C and the inside stopper B relative to the container body A, slightly scraping the inner circumferential surface 6a of the outer tube 6 where the protrusions 3 of the protrusion group region 3a of the locking ribs 2 had been wedged and interlocked. However, the portion of the inner circumferential surface 6a of the outer tube 6 facing the non-protrusion region 3b where no protrusions 3 are present will not be scraped. Therefore, even if the user rotates the screw cap C in the closing direction, the user will be made aware of the incorrect rotation direction by the feeling of the portion of the inner circumferential surface 6a of the outer tube 6 being scraped. Then, when the rotation in the closing direction is stopped, the outer tube 6 is no longer pushed apart and returns to its original state. The protrusions 3 will be able to wedged and interlock with the undamaged portion of the inner circumferential surface 6a of the outer tube 6 that was facing the non-protrusion region 3b, thereby preventing the inside stopper B from rotating together with the screw cap C without having to worry about the scraped portion of the inner circumferential surface 6a of the outer tube 6.

[0032] In this embodiment, on the outer periphery of the locking ridge 2 of the container body A, a protrusion group region 3a formed by protrusions 3 is formed in an arc-shaped range of 120°, and a non-protrusion region 3b is formed in an arc-shaped range of 60° at alternately opposing positions on the circumference. However, since it is sufficient that the protrusions 3 of the protrusion group region 3a bite into and engage with the inner circumferential surface 6a of the outer tube 6, preventing the inner plug B from rotating together with the screw cap C, and further that the non-protrusion region 3b has a location that does not scratch the inner circumferential surface 6a, it is sufficient that the range of the protrusion group region 3a is at least one location in a range of 60° to 120°, and the non-protrusion region 3b is preferably formed in a range of 50° to 120° (however, if there is only one protrusion group region 3a, the range excluding the protrusion group region 3a), and they are formed alternately with the protrusion group region 3a on the circumference.

[0033] When the screw cap C is continued to be rotated in the opening direction relative to the inside plug B, the rotation of the screw cap C rotates the mating protrusion 49 of the sealing cylinder portion 43, and the mating recess 20 of the transition plug body 13 of the inside plug B, which fits into the mating protrusion 49, also rotates around the columnar protrusion 16. As the transition plug body 13 is rotated relative to the inside plug B, the thin-walled weakened portion 12 connecting the transition plug body 13 to the lower end of the inner periphery of the dispensing cylinder 11 is broken.

[0034] Furthermore, when the screw cap C is rotated in the opening direction, the female thread portion 50 of the screw cap C and the male thread portion 25 of the inside plug B are unscrewed, and the screw cap C is lifted up relative to the inside plug B. Also, at the beginning of rotation, the tip of the vibrating arm 54 of the sound-emitting member 45 of the screw cap C abuts against the sound-emitting protrusion 28 on the top wall 10 of the inside plug B, and as the rotation progresses, the vibrating arm 54 moves while bending and deforming, the tip of the vibrating arm 54 overcomes the sound-emitting protrusion 28, the bent and deformed vibrating arm 54 returns to its original shape and vibrates, emitting sound.

[0035] As the screw cap C continues to rotate, the rotational force and lifting force applied to the transition stopper body 13 eventually cause the thin-walled weakened portion 12 to completely break, opening an outlet inside the dispensing tube 11, and the transition stopper body 13, which has been separated from the dispensing tube 11, is pulled up by the second engaging protrusion 48 of the sealing tube portion 43, which engages with the first engaging protrusion 19 of the peripheral portion 14, and rises together with the screw cap C. Furthermore, when the female thread portion 50 is unscrewed from the male thread portion 25 and the screw cap C is removed from the inner plug B, the transfer stopper body 13 is also removed along with the screw cap C, and the container with the open spout can be used.

[0036] After the contents are poured out, the screw cap C is rotated in the closing direction and screwed onto the inner stopper B, so that the seal portion 47 of the sealing tube portion 43 of the screw cap C adheres tightly to the inner circumference of the pouring tube 11, sealing the inside of the container. When the screw cap C is completely closed, the tip of the vibrating piece 54 of the sound-making member 45 again comes into contact with the sound-making protrusion 28 and vibrates, emitting a sound, so that the user can intuitively know that the screw cap C is completely closed.

[0037] When the lid is closed, the outer periphery of the lower end of the transfer stopper body 13 attached to the inside of the screw cap C comes close to the pouring outlet opened in the pouring tube 11 of the inner plug B and blocks the flow of the contents, so even if the container is turned over, the contents simply adhere to the underside of the transfer stopper body 13 and can be easily collected into the container body A, and the underside of the top wall 40 of the screw cap C and the area above the pouring outlet in the pouring tube 11 do not get dirty or the contents do not accumulate, so the inside of the pouring tube 11 can be kept clean.

[0038] After the contents have all been used, the gripping portion 34 is pulled to break the separation mechanism F, and the inside stopper B can be lifted up from the container body A, allowing it to be easily separated and disposed of.

[0039] Example 2 Next, a second embodiment will be described in which the configuration of the outer periphery of the locking ridge 2 of the container body A of the first embodiment is changed. In the following, the same components as those in the first embodiment are given the same reference numerals, and new reference numerals are given to changed components, and the explanation will focus on the differences. In FIG. 5, Aa is a container body, B is an inside plug attached to the container body Aa by plugging, and C is a screw cap attached to the inside plug B by screwing it on so as to be freely detachable.

[0040] As shown in Figures 5 and 6, the container body Aa has a locking rib 2 protruding from the upper outer periphery of the mouth 1, which fits over the inside plug B and holds it in place to prevent it from slipping out. The outer periphery of the locking rib 2 is divided into a protrusion group region 3a, in which a plurality of protrusions 3 with sharp tips are formed in an arc-shaped angular range, with R-shaped upper ends 3r that hang down axially from the upper ends 3r along the outer periphery of the locking rib 2 and protrude radially outward to a height L1; a non-protrusion region 3b, which is an arc-shaped angular range in which no protrusions 3 are formed; and a protrusion 60 with a blunt tip that protrudes radially outward to a height L2 greater than the protrusions 3, at the center of the non-protrusion region 3b. In this embodiment, as shown in Figure 6, the protrusions 3 are protruded with a height L1 of 0.4 mm, and the following are formed alternately in opposing positions on the circumference: a protrusion group region 3a formed in an arc shape with 11 protrusions 3 at 6° intervals within a 60° range centered at the 90° and 270° positions when viewed from above; an arc-shaped non-protrusion region 3b with no protrusions 3 formed within a 120° range centered at the 0° and 180° positions; and a trapezoidal protrusion 60 in a planar view protruding with a height L2 of 0.6 mm at the center position of the non-protrusion region 3b at 0° and 180°. When the height L1 of the protrusion 3 is 0.4 mm, the height L2 of the protrusion 60 is preferably set in the range of 0.5 to 0.8 mm.

[0041] Next, the manner of use and the effects of this embodiment will be described. In this embodiment, the transfer stopper cap is made by molding the inner stopper B and the screw cap C separately, then fitting the screw cap C onto the top of the inner stopper B to set it as a transfer stopper cap, and then fitting the attachment portion 5 of the inner stopper B into the mouth 1 of the container body Aa filled with the contents.

[0042] When the transition stopper cap set on the mouth 1 of the container body Aa is to be plugged, as the transition stopper cap continues to descend, the locking protrusion 31 of the inner stopper B climbs over the locking ridge 2, protrusion 3, and protrusion 60, and as shown in Figures 5, 6(b), and 6(c), the inner surface 6a of the outer tube 6, including protrusion 3 and protrusion 60 in the protrusion group region 3a, engages with the outer periphery of the locking ridge 2 with interference α and interference β, and the upper part of the locking protrusion 31 of the outer tube 6 engages with the lower part of the locking ridge 2, so that the set transition stopper cap is attached to the container body Aa so that it will not come off, and plugging is completed. After the stoppering is completed, the protrusion group region 3a of the locking ridge 2 has each protrusion 3 which bites into and engages with the inner surface 6a of the outer tube 6 by the amount of interference α, the protrusion 60 abuts against the inner surface 6a of the outer tube 6 by the amount of interference β, and the non-protrusion region 3b without protrusions 3 is attached with only the interference of the outer periphery of the locking ridge 2.

[0043] In this embodiment, when the user rotates the screw cap C in the opening direction, the locking protrusions 2 of the container body Aa, particularly the protrusions 3 in the protrusion group region 3a, bite into and engage with the inner surface 6a of the outer tube 6 of the inner stopper B, so that even when the screw cap C is rotated relative to the container body Aa, the inner stopper B does not rotate together with the screw cap C, and the torque rotating the screw cap C can be transmitted to the inner stopper B without waste.

[0044] Furthermore, when a user first mistakenly rotates the screw cap C in the closing direction, the protrusion 3 of the container body Aa bites into and engages with the inner circumferential surface 6a of the outer tube 6 of the inner stopper B, and further, the protrusion 60, which protrudes to a height greater than the protrusion 3, abuts against the inner circumferential surface 6a of the outer tube 6 of the inner stopper B with an interference β. When the screw cap C is rotated in the closing direction relative to the container body Aa, the user can sense that the rotation direction is incorrect by the sensation of a portion of the inner circumferential surface 6a of the outer tube 6 being scraped and the sensation of the scraped portion coming into contact with the protrusion 60. Furthermore, although the forced rotation slightly scrapes off the portion of the inner surface 6a of the outer tube 6 where the protrusion 3 is located, the portion of the inner surface 6a of the outer tube 6 facing the non-protrusion region 3b where there is no protrusion 3 is not scraped off, and when the rotation is stopped and the outer tube 6 is rotated in the opening direction, the protrusion 3 bites into and engages with the undamaged portion of the inner surface 6a of the outer tube 6 that was facing the non-protrusion region 3b, and is fixed in place, so that the inner stopper B can be prevented from rotating together with the screw cap C without having to worry about the scraped portion of the inner surface 6a of the outer tube 6. Other functions and effects are the same as those of the first embodiment.

[0045] Example 3 Next, a third embodiment will be described in which the configuration of the outer periphery of the locking ridge 2 of the container body A of the first embodiment is changed. In the following, the same components as those in the first embodiment are given the same reference numerals, and new reference numerals are given to changed components, and the explanation will focus on the differences. In FIG. 7, Ab is a container body, B is an inside plug attached to the container body Ab by stoppering, and C is a screw cap attached by screwing onto the inside plug B so as to be freely detachable.

[0046] As shown in Figures 7 and 8, the container body Ab has a locking rib 2 protruding from the upper outer periphery of the mouth 1, which fits over the inside plug B and holds it in place to prevent it from slipping out. The outer periphery of the locking rib 2 is divided into a protrusion group region 3a, in which a plurality of protrusions 3 with sharp tips are formed in an arc-shaped angular range, with R-shaped upper ends 3r that hang down axially from the upper ends 3r along the outer periphery of the locking rib 2 and protrude radially outward to a height L1; a non-protrusion region 3b, which is an arc-shaped angular range in which no protrusions 3 are formed; and a protrusion 65 with a blunt tip that protrudes radially outward to a height L2 greater than the protrusions 3, at a predetermined position in the non-protrusion region 3b. In this embodiment, as shown in Figure 8, the protrusions 3 are protruded with a height L1 of 0.4 mm, and are formed in opposing positions alternately on the circumference: a protrusion group region 3a formed in an arc shape with 18 protrusions 3 at 6° intervals over a range of 102° centered approximately at the 90° and 270° positions when viewed from above; an arc-shaped non-protrusion region 3b with no protrusions 3 formed over a range of 78° centered approximately at the 0° and 180° positions; and a trapezoidal protrusion 65 in a planar view protruding with a height L2 of 0.6 mm at a position 18° from the end of the adjacent protrusion group region 3a, 20° in the lid-opening rotation direction from the center position of the non-protrusion region 3b at 0° and 180°.

[0047] Next, the manner of use and the effects of this embodiment will be described. In this embodiment, the transfer stopper cap is made by molding the inner stopper B and the screw cap C separately, then fitting the screw cap C onto the top of the inner stopper B to set it as a transfer stopper cap, and then fitting the attachment portion 5 of the inner stopper B into the mouth 1 of the container body Ab filled with the contents.

[0048] When the transition stopper cap set on the mouth 1 of the container body Ab is to be plugged, as the transition stopper cap continues to descend, the locking protrusion 31 of the inner stopper B climbs over the locking rib 2, protrusion 3, and protrusion 65, and as shown in Figures 7, 8(b), and 8(c), the inner surface 6a of the outer tube 6, including protrusion 3 and protrusion 65 of the protrusion group region 3a, engages with the outer periphery of the locking rib 2 with interference α and interference β, and the upper part of the locking protrusion 31 of the outer tube 6 engages with the lower part of the locking rib 2, so that the set transition stopper cap is attached to the container body Ab so that it will not come off, and plugging is completed. After the stoppering is completed, the protrusion group region 3a of the locking ridge 2 has each protrusion 3 which bites into and engages with the inner surface 6a of the outer tube 6 by the amount of interference α, the protrusion 65 abuts against the inner surface 6a of the outer tube 6 by the amount of interference β, and the non-protrusion region 3b without protrusions 3 is attached with only the interference of the outer periphery of the locking ridge 2.

[0049] In this embodiment, when the user rotates the screw cap C in the opening direction, the locking protrusions 2 of the container body Ab, particularly the protrusions 3 in the protrusion group region 3a, bite into and engage with the inner surface 6a of the outer tube 6 of the inner stopper B, so that even when the screw cap C is rotated relative to the container body Ab, the inner stopper B does not rotate together with the screw cap C, and the torque for rotating the screw cap C can be transmitted to the inner stopper B without waste.

[0050] Furthermore, when a user first mistakenly rotates the screw cap C in the closing direction, the protrusion 3 of the container body Ab bites into and engages with the inner circumferential surface 6a of the outer tube 6 of the inner stopper B, and further, the protrusion 65, which protrudes to a height greater than the protrusion 3, abuts against the inner circumferential surface 6a of the outer tube 6 of the inner stopper B with an interference β. When the screw cap C is rotated in the closing direction relative to the container body Ab, the user can sense that the rotation direction is incorrect by the sensation of a portion of the inner circumferential surface 6a of the outer tube 6 being scraped and the sensation of the scraped portion coming into contact with the protrusion 65. Other functions and effects are the same as those of the first embodiment. [Industrial Applicability]

[0051] The container with a transfer stopper cap of the present invention is suitable as a container with a transfer stopper cap that can be widely used for containers of food, beverages, seasonings, etc., because even if the screw cap is rotated in the closing direction relative to the container body when opening it after the transfer stopper cap is attached to the mouth of the container body by plugging, the inner stopper does not rotate together with the screw cap, and the screw cap can be reliably rotated relative to the inner stopper to remove the transfer stopper body from the inner stopper and open it.
