Carrying out the invention  Best form for

The present invention relates to a cap-fitted container in which a cap is mounted on a neck of a container body, a cap body which is covered by an inner cap directly on the neck of the container body and a cap body which is covered by the inner cap, The cap body is provided with a cutting blade for breaking the thread at the start of use. In addition, an unsealing prevention ring for preventing unsealing in an unused state is provided.

The cap mechanism is locked in the unsealing and the use state of the seal by tapping at the time of use of the cap body. The relationship between the engaging force between the container body neck portion and the inner cap and the force of the engagement lock between the inner cap and the cap body is made weaker than that of the latter.

Further, in the initial operation, in order to complete the initial operation by using the auxiliary engagement structure even if there is a problem in the engagement structure with the inner cap and the container neck, the engaging rib of the container neck is moved up and down A separate configuration was adopted.

Further, the present invention is characterized in that a sealing means is provided for separating and leaving the sealing member at one position, and holding the sealing member after the sealing is connected to the sealing cap. As a means for cutting out a circular part while leaving a part of the seal member, a cylindrical body having two cutting blades at the tip end thereof is used, and when the cylindrical body is pivoted close to the yarn, The cutting locus of one of the cutting blades is stopped just before the other cutting point and the setting of two cutting blades is designed so that the cutting locus of the other cutting blade can pass through one cutting point. This design is related to the arrangement of the circumference, the size and shape of the blade, and the like.

In the case of a circumferential arrangement, it is possible to arrange the point-symmetrical arrangement, in the case of the symmetrical arrangement, the height of the blade tip may be changed, and in the case of the mountain-shaped blade, the taper angle may be changed. It can also be realized by combining these.

The cutting operation can be performed arbitrarily, but it is possible to securely prevent cutting by regulating the cutting end point. For example, the inner cap and the cap main body may be formed in a screw engagement relationship, and the end point of the screw engagement and the cutting operation may be synchronized.

The material may be a container body, the cap may be made of synthetic resin, metal, or the like.

Each component will be described below.

1. Full Configuration

The present invention comprises a container body and a cap mounted on the container body neck. The relationship between the engaging force between the container main body portion and the inner cap and the engaging lock force between the inner cap and the cap main body is configured such that the former is weaker than the latter.

The engagement between the neck portion of the container body and the inner cap is constructed by separately constructing the horizontal direction and the vertical direction and the vertical engagement mechanism is structured such that the longitudinal ribs provided in each of the vertical ribs are entangled, The engaging mechanism is constituted by assembling the annular protrusion provided on the inner cap on the lower side of the annular protrusion provided on the neck of the container body. With this configuration, even if the engagement of the longitudinal ribs is loosened and the rotation is permitted, the protrusion on the horizontal annular portion of the cap keeps the engagement, so that the ejection preventing function is exhibited.

In addition, the cap of the present invention is provided with a seal member. In the unused state, the contents are not leaking from the main outlet, and an unsealing ring is provided to prevent unsealing of the seal member. When the cap is inserted into the cap, the thread is opened and closed in accordance with the tapping operation so that the thread is prevented from rotating in the reverse direction at the non-returning end.

In addition, the cap used in the present invention is a cap having a seal opening structure. Further, an unsealing prevention ring for preventing the unsealing in the unused state is applied as necessary.

2. Container body

The container body is provided with a cylindrical neck portion at its upper portion, and one or more vertical ribs are formed at the base end portion of the neck portion. In the case of manufacturing the container body by blow molding or injection molding, it is appropriate to set the number to 1 to 4 in consideration of the deformation.

An annular protrusion is formed above the cylindrical portion forming the neck. The annular protrusions may be integrally formed in a ring form or may be provided in a dotted pattern. It is preferable to use an integral ring shape in view of ease of molding, and in the case of a point shape, 1 to 4 are suitable. The annular projecting portion is formed so as to be positioned above the annular projecting portion provided on the inner cap so as to complete engagement when the cap is mounted.

The annular protrusions are installed on the upper side of the upper end of the vertical ribs. It is preferable that a tapered surface with a taper is formed on the end surface of the longitudinal rib. The resistance in the rotating direction can be adjusted in accordance with the direction of the data. The vertical ribs can be separated vertically, so that the upper side is always the main longitudinal rib to be engaged, and the lower side is not engaged in the normal state, In case of a problem, the auxiliary vertical ribs are used so that the engagement can be maintained.

The container body is suitable for a bottle having transparency that allows the remaining amount to be visually confirmed. In terms of transparency, synthetic resin or glass can be used. For example, a cosmetic container.

3. Cap

The cap is composed of a cap and a cap body. If necessary, an unsealing ring is interposed in an unused state.

3-1 Inside cap

The cap has a sealed outflow hole and is mounted on the neck of the bottle container. It has a double cylindrical shape and is fitted with the neck of the bottle sandwiched therebetween. The inner cylinder forms an outlet hole, and the bottom portion is sealed to form a seal member.

On the inner circumferential surface of the outer cylinder, annular protrusions are formed in the horizontal direction, and a plurality of vertical ribs are provided below the annular protrusions. The annular protruding portion is formed at a position located below the annular protruding portion on the container main body side. A plurality of longitudinal ribs are formed on the inner circumferential surface of the cylinder below the annular protrusions. The vertical ribs on the side of the neck of the container body are inserted between the vertical ribs, and the rotation in the horizontal direction is blocked to establish the engagement relationship. It is preferable that a taper is also provided on the end face of the vertical rib. By changing the shape such as the direction and size of the tapered surface, the resistance in the rotating direction can be adjusted. Of course, the resistance adjustment in the pivotal direction is ultimately determined in relation to the vertical ribs of the container main body.

A small convex annular protrusion can be provided on the upper part of the annular protrusion to form a recess between the two protrusions. By holding the annular projecting portion of the container neck in this recess, the position of the inner cap in the normal vertical direction can be determined. By this positioning, a gap can be formed above the top of the container neck.

A male thread is formed on the outer circumference of the outer cylinder. If this screw is made of two sets of threads, the coupling distance can be shortened to obtain the strength. The base end of the outer periphery is provided with an engaging tongue and engages with the engaging tongue provided at the container main body side against the engaging end so as to lock the screw. In this case, the engaging member of the cap main body stuck tightly in these small intervals, and lock function in the forward and reverse directions is performed. Further, in order to align with the container body, the engaging marks can be provided on the lowermost flange.

The sealing film as the seal member can be bent into a dish shape. It is preferable that the curvature is equal to the curvature of the inner circumferential diameter of the neck of the bottle so that the back surface stably contacts the neck of the bottle when the degree of curvature is opened.

3-2 Cap Body

The cap main body has an approximately cylindrical shape, and has a main outlet at its front end, a cap with a hinge for opening and closing the main outlet, a female screw for screwing into the cap, a cylindrical blade for actual cutting leading from the main outlet to the inside, And an engaging member for engaging the engaging member of the inner cap. An engaging mark can be provided on the outer peripheral lower end of the cylindrical portion.

In the cap body, the cap is cut by the cap screw, and the cylindrical blade cuts the sealing film, and the opening is completed at the same time as the screwing is completed. Further, the cap main body is locked at the threaded end, thereby constituting a reverse rotation preventing mechanism. The configuration of the cylindrical blade for cutting the sealing chamber is as follows.

The two cutting blades are formed such that the sealed sealing film is cut along the inner edge and separated substantially over the whole circumference to leave a part as a connecting piece. For example, a point-symmetrical arrangement, a mountain-shaped blade having a different size, a mountain-shaped blade having a different gradient, and a blade having a different tip height. Opening Bongdong A small turn is done. The rotational cutting by the two cutting blades can be realized by preventing the cutting locus of each cutting blade from being partially overlapped. By regulating the turning range, an accurate cutting locus can be realized, and a connecting piece can be reliably left. If two connecting pieces are formed, the seal member may not be sufficiently opened, which may interfere with smooth pouring (pouring). If completely separated, the thread may float in the bottle container main body, or may leak into the injection hole, thereby inhibiting the outflow. If the bottle container is transparent, impurities are mixed. Especially, cosmetic or beverage products have poor feeling.

The opening of the opening piece can be kept constant by making the contact portion of the cutting blade stopping in contact with the remaining connecting piece to have a downward biasing shape of the opening piece. For example, if the cutting end portion is a downwardly inclined surface, it is possible to make a downward bias by the contact. Further, if the cutting edge is formed so that the blade is finished at the cutting end point and the cylindrical body with the blade is further inserted from the cutting end point, the connection is compressed by the outer peripheral surface of the cylindrical body with the blade, . However, it is important to be careful not to tear the connection piece, because the risk of tearing the connection piece when the entry is deepened.

As means for restricting the rotation of the cylindrical body provided with the two cutting blades, it is possible to screw the inner cap and the cap body together so that one connecting piece is left at the end point of the screwing.

By forming the one connecting piece by cutting using two cutting blades located on one circumference, the cutting end point exceeds the cutting point of one of the two cutting points and the cutting end point at which the connecting piece is separated Since the sound is generated, the end of the opening operation can be confirmed.

The regulation of the rotation of the two blade forming and opening operations is as follows.

(1) With a cutting blade, a cap provided with a cylindrical body for opening a seal, wherein two cutting blades are provided and the opening distances by the two cutting blades are different, and after the opening operation, Cap with seal opening mechanism.

(2) The configuration in which the opening distances by the two cutting blades are different may be realized by differentiating the point of symmetry and / or the tip of the cutting blade at the end of the cylinder.

In the case of the point-to-point symmetry, that is, when the cutting blades are arranged with different intervals on the circumference, when two cutting blades simultaneously start cutting, when cutting a length corresponding to a short interval, The car will remain as a connecting piece.

In addition, when a difference is made between the height of the tips of the two cutting blades, when the cutting operation is performed while entering the rotation, the two cutting blades have a time difference at the cutting start timing, and the length corresponding to the time difference can be left as a connecting piece.

(3) A cap having a cap body provided with a cylinder capable of advancing and retracting in an extruder, in which two cutting blades are arranged in a point-symmetrical manner with respect to the sealing film for closing the extruder.

(4) As an example of concrete aspect of the point-symmetric arrangement, it may be stipulated as follows. A cap having two cutting blades for breaking an encapsulating film by rotating the cap body in a normal direction, the two cutting blades having a point-to-point symmetry with respect to the tip of the cylindrical body And the relationship of the positional relationship in the circumferential direction and the direction of the breaking rotation in which the tip of one of the cutting blades is 0 DEG with respect to the axis of the cylindrical body is set as follows so that after the breaking operation, Wherein a sealing state of the sealing film is formed.

Position of one cutting blade A = 0 °

The position of the other cutting blade B is θb> 180 °

The breaking rotation angle? Cut < [theta] b of one cutting blade A

The cutting rotation angle? Cut +? B> 360 ° of one cutting blade A

(5) Further, by defining the screw connection relation, the remaining connecting piece that is not cut can be regulated. For example, a cap having two cap cutting blades for breaking the sealing film by rotating the cap body in the forward direction, the cap being formed of a cylindrical body having a male thread on its outer periphery, The cap body is a tubular lid having an inner diameter formed with a female screw threadably engaged with the male screw of the inner cap. The cap body is a tubular lid having an inner diameter, And the cutting blade has two cutting blades. The cutting blade has a large interval, which is an angle between the blades, and a large gap, which is an angle between the blades And the tip of the cutting blade provided on the cap body is positioned at the position of the closure that breaks the sealing film of the inner cap. Wherein the cap is set in a screw engagement relationship between the inner cap and the cap body in a range in which the upper limit of rotation is larger than the angle between the capsules and smaller than the angle between the caps.

Further, in this case, by using two cylindrical cutting blades with a cutting blade formed so that the cutting edge is finished at the cutting end point, downward urging of the opening piece at the cutting end point can be maintained. Further, when the threading is progressed in a range not exceeding the length of the connecting portion from the cutting blade end point, the connecting piece is constrained by the outer peripheral surface of the cylindrical blade, so that the downward posture of the opening piece can be further stabilized.

3-3 Hinge Cap

A cap with a hinge may be provided on the tip side of the cap body. After opening the hinge cap, the contents can be poured by opening and closing the hinge cap. It can be used conveniently and cleanly for applications where it is released after opening a little. For example, it is suitable for cosmetic containers.

In the present invention, when the cap body is turned by mistake, the cap may be peeled off. However, in the present invention, the cap is allowed to rotate between the cap and the neck of the container body So that the accident can be prevented.

3-4 Release ring

It is preferable that the unsealing prevention ring is provided separately from the cap body and the cap. As the unsealing means indicating the unused state, means for connecting the inner cap and the cap body in a strip shape (for example, Patent Document 3) are generally used. As a new means, the applicant of the present invention proposed a ring-shaped opening preventing member which is separately formed as shown in Japanese Patent Application Laid-Open No. 2006-193202.

Fig. 1 is a partially enlarged view of the state where the cap of this embodiment is mounted on the container body. Fig. 1 (a) shows the unused state, and Fig. 1 (b) shows the unsealed state.

The inner cap 3, the opening prevention ring 5 and the cap body 4 are mounted on the neck portion 21 of the container body 2 in this order. The inner cap 3 has the tip end portion of the neck portion of the bottle container entered into the cavity 35 and the annular protrusion portion 22 provided on the neck portion of the bottle container main body 2 is accommodated in the annular recess portion 34a of the inner cap, And an annular protruding portion 34b provided on the neck portion is positioned at the lower side to be engaged and prevented from being withdrawn. The longitudinal ribs 23a and 23b formed on the neck base portion of the bottle container are engaged with the longitudinal ribs 36 provided on the inner surface of the base of the inner cap to regulate the rotation in the circumferential direction. The inner cap 33 of the inner cap and the female screw 42 of the cap body are screwed to each other. The screw adopts a two-threaded screw to achieve a stable screw connection with a small number of revolutions. In order to maintain the unused state, the opening prevention ring 5 is interposed in the lower part of the cap body to block the entry of the screw engagement, thereby preventing the cylindrical cutting blade 70 from falling down and coming into contact with the sealing film 7.

By covering the inner cap 3 with the neck portion 21 of the container body 2 and pushing it strongly, the engagement of both is completed, and the two annular protrusions provided horizontally are engaged with each other, The vertical rib of the neck portion side of the container enters between the plurality of installed vertical ribs, thereby restricting the rotation. In the practical process, the container is filled with the contents, and the cap with the cap, the unsealing ring and the cap body set is pushed into the neck of the bottle container to complete the unused container with cap.

In the use state, the cap body and the unsealing ring are peeled together first, only the cap main body is reattached, and the threaded connection is continued until the end point so that the periphery of the sealing film (7) 79) to leave the open state. Thereafter, the hinge cap 6 is opened to take out the contents, and the contents can be used.

In this example, the sealing film 7 is formed in a dish shape bent downward by? D. In Fig. 1 (b), this DELTA d is formed with a curvature in contact with the neck portion 21 of the container body. The sealing film cut by such a state becomes a stable posture, and it is possible to maintain a good use state after opening.

The container body is illustrated in FIG. 2, and a neck is formed so as to cover the inner cap. At least a part of the container is preferably transparent. It can be made of a transparent synthetic resin, and can be produced by blow molding using PET or the like. 2 is a side view of the container main body 2 in which a neck portion 21 formed by narrowing a shoulder portion is provided and an annular protrusion 22 and a longitudinal rib 23 are formed on the neck portion. The vertical ribs 23 may be composed of two main longitudinal ribs 23a and auxiliary longitudinal ribs 23b. Although a city is shown as being divided into two types, it is also possible to have one continuous body. When the main longitudinal rib 23a is broken due to excessive rotation in the unused state or the like, the auxiliary longitudinal ribs 23b and the longitudinal ribs 36 are engaged with the inner longitudinal ribs 23b , It can be set to the initial state of use start. Particularly, since there is a gap in the container neck portion, by pushing the cap body strongly, the engaging force with the auxiliary rib 23b can be increased, and the setting becomes clear.

Although the annular protruding portion 22 is formed in a continuous ring shape, it is also possible to provide a plurality of pointed projections. One or more vertical ribs 23 may be provided. In the case of a plurality of longitudinal ribs, it is preferable that the number of longitudinal ribs is set to four at intervals of 90 degrees. The same applies to the case where the annular protruding portion is a pointed projection.

The configuration of the cap body will be described with reference to Figs. 3 and 4. Fig. Fig. 3 is a sectional view of the cap body with the hinge, Fig. 4 (b) is a view from the lower side, Fig. 4 (a) is an external view of the cap body with the hinge, And a cap is opened.

The cap main body 4 is provided with a cylindrical portion 41 having a female screw 42 covering the inner cap and a hinge cap 6 provided at the end of the cylindrical portion 41. And a cylindrical cutting blade 70 provided with a cutting blade at the tip side is provided at the center. The base side of the cylindrical cutting blade becomes the main outlet 65. Two outer joining tanks 47 are provided inside the base end of the cylindrical portion 41 so as to be opposed to each other by 180 占 and engaged with the inner engaging jaw 38 provided at the base end portion of the inner cap, Construct an engagement relationship. In addition, two engaging projections 44 are provided in opposition to the engaging jaws 47 by 180 degrees. The engaging convex portion 44 comes into contact with the high-stage portion 39a provided in the inner cap to perform a rotation stop function in the forward direction (positive direction). An engaging mark 45 can be provided on the outer peripheral proximal end portion of the cylindrical portion 41 corresponding to the outer- It can be confirmed that the mounting is completed when the engaging marks coincide with the engaging marks provided on the inner cap.

Fig. 4 (a) shows an appearance of the cap body 4 viewed from the side. And the engagement mark 45 is slightly expanded on the side surface. Fig. 4 (b) shows a cross-sectional view of the cap body showing a state in which the hinge cap 6 is opened. One end of the stopper 64 is connected by a hinge 61 and the other end is formed with a handle 63. A stopper 62 for blocking the main outlet 65 is provided at the center.

An example of the configuration of the cylindrical cutting blade is shown in Fig. The cylindrical cutting blade 70 is provided with two cutting blades A 71 and a cutting blade B 72. The cutting blade A has a substantially mountain shape as viewed from the side and has a flat portion 78, A cutting blade end 74 formed thereon, followed by a cutting blade beveled surface 74, and a flat portion 75. The rear side of the cutting blade is connected to the flat portion through the rear bevel surface 77. [ The two cutting blades are formed with a large spacing of 210 ° and a small spacing of 150 °. Opening rod Small, but the connecting piece with a cutting angle of 150 ° and 40 ° remains without being separated. Since the cutting edge of the cutting blade is provided with a flat portion of 20 degrees at the end of the cutting edge, when the cutting edge portion 74 of the cutting edge is inserted into the sealing film while cutting, the cutting edge is cut by 170 degrees. 40 degrees.

The configuration of the inner cap will be described with reference to Fig. 5 (a) is a top view, (b) is a sectional view, (c) is a bottom view, and FIG.

The inner cap has a substantially cylindrical outer appearance and a double structure having a cylinder with a small diameter on the inner side. The bottom of the small diameter cylinder is sealed with a sealing membrane. And the tip of the neck of the container body is inserted into the gap portion formed by the double cylinder.

More specifically, the inner cap 3 is formed in two by the inner cylinder portion 31 sealed by the sealing film 7 and the outer cylinder portion 31 formed with the male screw 33, As shown in Fig. The outer base portion of the outer tube 31 is provided with an engaging jaw 38 and an engaging mark 38c which are engaged with projections of the cap body or the opening prevention ring. In addition, a sub-group tank 38b opposing the engaging jaw 38 with a small gap is provided, and a small gap between the two jaws forms the engaging recess 37. [ The state in which the outer collective tank 47 provided in the cap body is stored in the engagement concave portion 37 beyond the bulge portion of the back portion of the inner engaging jaw 38 becomes the use setting state. The external combined tank 47 is prevented from rotating in the reverse direction by engaging with the engaging jaw 38, and the cap body is not peeled off from the inner cap in the used state. Further, a high-end portion 39a is provided so as to abut against the engaging convex portion 44 of the cap main body, and thereby to prevent the over-rotation in the forward direction. A plurality of longitudinal ribs 36 and 36 ..., annular recesses 34a and annular protrusions 34b are formed on the inner surface of the outer tube 31. The longitudinal ribs 23 The vertical ribs 23a and the auxiliary vertical ribs 23b) and the annular protrusions 22 so as to be in a covering relationship in which the prevention of rotation is prevented. The front end surface of the vertical rib 36 is formed by a tapered inclined surface 36a.

An opening prevention ring 5 is illustrated in Fig. (Stepped) cylindrical shape, and is mounted on the inner cap, and the base portion of the cap body is mounted on the upper small-diameter portion. Indicates the unused state in the mounted state, and prevents the sealing film from contacting the cutting blade. The recess 57 and the unsealing ring convex portion 54 are formed for engagement in order to regulate the inner cap and the cap body and the engagement position.

The engaging relationship between the cap and the container main body of the present embodiment will be described. The cap is directly in contact with the container main body, and the cap main body is put on the inner cap. Since the inner cap and the cap body are in the screw engagement relationship, the joining mechanism of the inner cap and the neck of the container body is arranged so that the convex-shaped annular members in the horizontal direction are arranged vertically so as to be prevented from being withdrawn, And are constituted by intertwining each other. The cap body is knotted and locked at the punching end point. However, if the cap body is strongly pivoted in the direction of unintentional loosening, the lock may be broken, leading to an accident that the stored contents leaks. In order to prevent such an accident, in the present embodiment, the front end surface of the longitudinal rib is formed as an inclined surface with a taper. It is possible to prevent the cap body from being peeled off from the inner cap by designing the engaging force smaller than the lock holding force of the screw engagement when the cap is strongly turned in the direction of loosening the screw connection by arranging the inclined surfaces of the longitudinal ribs . In addition, although the engaging force in the forward rotation direction is larger than the engaging force in the reverse rotation direction, when the cap is rotated in a normal direction with a very large force, if the longitudinal rib is designed so as to be bent, a rotational force It is possible to prevent an accident that the inner cap and the rib structure of the container neck are absorbed and the cap is peeled off. Particularly, in this embodiment, it is also a feature that a part of the yarn is left without being separated. Since the opening operation is defined according to the amount of knocking, there is a risk that the yarn is completely separated by excessively turning the yarn. It is important to limit screwing.

In addition, in the unused state, the opening prevention ring is interposed between the inner cap and the cap body, the cap main body is peeled off at the start of use to remove the opening prevention ring, and the cap body is screwed to the outer periphery of the inner cap again, And the cap is completed. For example, there is a risk that the cap body is peeled off once it is in the use state, and then the cap is closed by unsealing the cap body. In the present embodiment, in addition to the structure in which the cap body is mounted in the use state, when the strong reverse rotation force is applied, the engaging force between the longitudinal ribs is smaller than the lock retention force, , The cap is not peeled off. Therefore, this embodiment also has a tamper-proof function.

A specific configuration will be described with reference to FIGS. 7 and 8. FIG.

Fig. 7 (a) shows an engagement relationship in a state set to the use state. A cylindrical neck portion 21 of the bottle container and two main longitudinal ribs 23a provided on the neck portion are provided on the innermost side. An inclined surface 23c having a taper is formed at the tip of the main longitudinal rib 23a. And a main longitudinal rib 23a is set between a plurality of longitudinal ribs 36 provided on the inner circumferential surface of the inner cap. The tip end of the vertical rib 36 is also formed with a tapered surface 36a. These inclined directions are opposed to each other, and when the cap in the set state is reversely rotated to be peeled off, the engagement is easily peeled off along the inclined surface. Since a plurality of the longitudinal ribs 36 are provided, the next longitudinal rib 36 becomes a resistance beyond one longitudinal rib, and therefore, free rotation is not achieved.

The locking configuration of engagement between the inner cap and the cap body engages the inner engaging jaw 38 provided on the outer periphery of the inner cap and the outer joining tank 47 on the cap body side in the reverse rotation preventing direction. The engaging convex portion 44 provided on the cap body comes into contact with the high-end portion 39a provided in the inner cap and is stopped to rotate.

In the present embodiment, the sub-scale tank 38b is provided so as to face the inner engaging jaw 38, and an engaging recess 37 is formed therebetween. And the outer-group composite tank 47 is fitted to the engaging concave portion.

Fig. 7 (b) shows the state during the operation at the start of use. The release preventing ring is removed, and the end of the cap body is tapped. The outer surface of the outer joining tank 47 is brought into contact with the rear surface of the inner joining tank 38 so that the outer joining tank 47 is fitted to the engaging concave portion 37 beyond the back surface of the outer joining tank 47, The coupling is completed. On the other hand, the engaging convex portion 44 of the cap body abuts on the high-end portion 39a of the cap so as to stop rotation. In this example, the main constitution of over-rotation prevention is the abutment of the engaging convex portion 44 and the high-end portion 39a. In the case of tightly turning, the safety is improved by designing the vertical ribs such that the screwing engagement between the inner cap and the cap body is not broken by this abutment and the vertical ribs are bent.

For example, specifically, in the case where the breaking torque of the engagement of the longitudinal ribs in the direction of reversing the cap is set to 3 kgf / cm after the setting is completed and the screws are excessively tightly tightened in the forward direction, The breaking torque of the fit is set to 10 kgf / cm. Further, at the time of initial use setting, when the cap body is rotated, the torque exceeding the inner cap is set to 4 kgf / cm, and the engaging torque of the set after setting is set to 10 kgf / cm. By setting in this way, it is possible to easily confirm that the adult can be initially settled by the turning resistance received when the cap body is turned, and at the same time, when the container body is rotated in the reverse direction by mistake, The cap body is idly rotated because it is smaller than the combined force between the cap and the cap body. As a result, the cap body is prevented from being peeled off.

It is also possible to visually confirm that the setting is completed in a state in which the engaging marks 45 and 38c are aligned with each other.

Fig. 8 is a schematic outline of the setting state of the cap body and the inner cap in Fig. 7 (a), and thus will not be described in detail.

In the present embodiment, the virgin state is clarified by interposing the opening prevention ring, and since the opening prevention ring is not provided with a separate joining piece, no trace of removing the opening prevention ring is left. In addition, since it is not an over cover for preventing opening, the design of the use state can be displayed as it is.

As a result of the tapping operation of the cap main body, the seal is opened and a part of the cut seal film remains, so that the seal thread is held at a specific position, and the seal thread is not clogged or floated in the bottle container Do not.

Further, even if the cap is strongly reversely rotated, since the engaging resistance between the inner cap and the container neck in the longitudinal direction is weakened, the cap body is idled without being peeled off. Further, in the case of strong forward rotation, the longitudinal ribs are bent so that the piercing structure can be prevented from being broken.

Since the inner cap and the container main body portion are separated from each other by the horizontal engaging and vertical engaging mechanisms, there is no influence on the engaging prevention of the escape prevention even if the engagement of the vertical ribs is loosened.

The present embodiment is a cap-fitted container in which the constitution is organically related to improve the appearance and safety.

The opening of the thread is as follows. Will be described with reference to FIG. 10 shows the positional relationship of the cylindrical blade 70 in a state in which the inner cap is viewed in a plan view. The sealing film 7 provided in the inner cylinder 32 of the inner cap is shown at the center. The state of the two cutting blades A, B (71, 72) in the inner cylinder 32 is shown in a vertical section. 10 (b) shows a state in which the unsealing rings are removed, and when the cutting blades A, B (71, 72) start cutting the sealing film 7 And Fig. 10 (c) shows a state in which the cutting has ended with leaving the connecting piece 79. Fig. The cutting blade A (71) and the cutting blade B (72) formed at the tip of the cylindrical blade (70) have the same shape and roughly mountain shape of the same shape.

10 (a) shows the positional relationship of each member on a circular coordinate axis with the rear end of the flat portion 78 of the cutting blade A 71 being 0 °. The rear end of the flat portion 78 of the cutting blade B is disposed at 210 占 and each flat portion has a length of 20 占 and the base of the cutting blade end bevel surface 74 which is the bottom of the cutting blade and the base of the rear bevel surface 77, And has a length of 90 degrees. In the vertical section, the flat portion 78 of the cutting blade is not in contact with the sealing film 7.

Fig. 10 (b) shows a state at a time point when the sealing film of the two sheets of cutting blades is cut by tearing at the position where the opening prevention ring is removed and screwed back and moved 45 degrees from the position of Fig. 1 have. The rear end of the flat 78 of the cutting blade B is at 255 degrees.

Fig. 10 (c) further shows a state in which the cutting is finished by turning by 135 degrees. The rear end of the flat portion 78 of the cutting blade A (71) is located at 180 degrees. The rear end of the flat 78 of the cutting blade B is 30 degrees. In the vertical section, the cutting blade A 71 is in the state of 83a, and the cutting blade front beveled surface 74 is in a state of tearing the sealing film 7, and the tip oblique face is 15 ° and the flat portion 20 ° is added 170 ° is the angle cut by the cutting blade A 71, and 215 ° on the coordinate axis. Therefore, the difference of 255 degrees from the rear end of the flat portion 78 of the cutting blade B in Fig. 10 (b) is not cut by 40 degrees, and corresponds to a portion forming the connecting piece 79. [

A series of thread-engaging rotations is configured to be realized within 360 °. The opening prevention ring is 180 DEG and the turning rotation is 180 DEG with sufficient clearance. This precise control by such a small rotation angle is realized by a screw coupling structure using a twin screw.

On the other hand, the cutting blade B 72 at the cutting end is in a state of 83b in the longitudinal section, and the cutting blade end 73 of the cutting blade B 72 is 50 ° in plan view. Therefore, it passes the cutting position 45 [deg.] Of the cutting blade A (71), and this portion is separated. Even in consideration of the elongation of the synthetic resin, the cutting edge end bevel surface 74 of the cutting blade B (72), as well as the cutting blade A, .

Considering this embodiment in addition to claim 4, it is as follows. In this embodiment, since the slope of the flat or mountain-shaped slope of the cutting blade has a substantial cutting function, it is necessary to consider the application in consideration of the amount. In the case of a bar-like cutting blade such as a needle, this relationship need not be considered.

(1) The position of one cutting blade A = 0 °: the rear position 45 ° of the flat 78 of the cutting blade A 71 in FIG. 10 (b) (Here, this corresponds to 45 DEG)

(2) The position of the other cutting blade B? B> 180 占: The rear position 210 占 of the cutting blade 78 of the cutting blade B 72 in Fig. 10 (a) do)

(3) Breaking rotation angle of one cutting blade A? Cut <? B: Cutting angle of the cutting blade A (71)

(4) Cutting angle? Cut +? B> 360 ° of one cutting blade A: angle 170 ° cut by the cutting blade A 71 + flatness of the cutting blade B 72 78 &lt; / RTI &gt;

Since the breaking sound is generated at the separation end point of the cutting blade B 72, the user can reliably confirm that the yarn has been unsealed, so that it is not necessary to make a small amount of unnecessary rotation and can be relieved. Since the cutting blade is inserted by screwing, the opening operation can be performed with a small force compared to the force to be pushed by the straight.

The remaining connecting piece 79 is bent inward by the flat portion 75 of the cutting blade A 71 to stabilize the posture so that the sealing film returns even if the hinge cap is opened and shaken out So that a smooth pouring operation can be performed.

The sealing film can be bent and brought into close contact with the neck of the container body, and the posture of the sealing film after the opening can be stably maintained.

The cap of the present embodiment can be covered by integrally combining the cap, the unsealing prevention ring and the cap body, and pressing the cap on the neck of the bottle container main body in a state of filling the contents. The bottling process can be simplified.

The present embodiment is a cap-fitted container in which the constitution is organically related to improve the appearance and safety.

Example 2

Embodiment 2 will be described with reference to Figs. 11 and 12. Fig. The parts not mentioned are, in principle, common to the first embodiment.

(a) shows an unused state, and (b) shows a state in which a yarn is unsealed. 12 is a cross-sectional view of each component member shown in Fig. (a) is a sectional view of the container neck, (b) is an inner cap sectional view, (c) is a sectional view of the cap body, and a right half (c1) shows a state in which an opening ring is dampened.

The second embodiment is different from the first embodiment in that upper annular protrusions 34c are provided as annular protrusions on the upper side of the annular recess 34a of the inner cap to form annular recesses 34a and 34b, And the auxiliary vertical ribs 23b provided on the container neck are horizontally arranged. In the normal state, the vertical ribs 36 of the cap and the auxiliary vertical ribs The ribs 23b are formed so as not to engage with each other and are structured to engage with each other when the cap body 4 is strongly pushed.

As shown in Figs. 11 (a) and 12 (c) (c1), when the opening prevention ring 5 is strongly rotated in the forward direction in a state of being dampened, the main longitudinal rib 23a provided on the neck of the container is broken There is a danger. In such a case, there is a risk of idling in the forward rotation direction even if the cap preventive ring 5 is removed and the cap body 4 is screwed again at the start of use. At this time, when the cap main body 4 is strongly depressed toward the container side, the auxiliary longitudinal ribs 23b and the longitudinal ribs 36 are engaged with each other, so that the auxiliary longitudinal ribs 23b and the longitudinal ribs 36 can be assembled into a set state of use.

The mechanism for assisting the forced assembly is an upper annular protrusion 34c provided on the inner cap and an upper gap 35b formed above the container 21b. Since the upper annular protruding portion 34c is present, the inner cap 3 is supported on the annular protruding portion 22 of the container neck and does not descend. The upper gap 35b is present in the upper part of the container 21b of the container neck portion so that the relationship between the longitudinal ribs 36 of the inner cap and the auxiliary longitudinal ribs 23b is not normally held have.

When the main longitudinal rib 23a is broken and it is difficult to engage with the longitudinal ribs 36 as described above, the cap 3 is pressed against the upper gap 35b by strongly pushing the cap main body 4 toward the container side, So that the lower side of the longitudinal ribs 36 and the auxiliary longitudinal ribs 23b provided on the container neck are engaged with each other. The upper annular protruding portion 34c is formed in a convex shape smaller than the annular protruding portion 34b so as to increase or decrease the pressing down resistance. In addition, the same contents as those of the first embodiment are allocated to avoid duplication.

In the second embodiment, it is possible to provide a container improved in the ability to cope with an unexpected situation when the first setting failure occurs at the start of use.
