The sealing band 51 has a band-like shape and substantially circulates, and has a thickness as a spacer for preventing the cutting blade 36 from coming into contact with the sealing film 47 of the inner plug 4 assembled to the container body when not in use. have. The sealing band 51 has an inner diameter that can cover the lock ring 6. One end of the sealing band 51 extends from the side to form an opening knob 53.
The remaining circumferential band 52 is a cylinder having a smaller diameter than the sealing band 51 and in close contact with the outer circumferential surface of the inner plug 4. A convex step 55 is formed on the outer surface of the remaining band 52. This convex step portion comes into contact with the convex portion of the inner wall surface of the cap and becomes a rotational resistance in the direction in which the cap is loosened. Further, in the illustrated example, the convex step portion 55 is provided with the small convex step portion 55a and the large convex step portion 55b in the vertical direction. The small convex step 55a on the upper side is in contact with the inner wall surface of the cap when not in use, and the large convex step 55b on the lower side is in contact with the inner wall surface of the cap when in use, thereby increasing the rotational resistance. .
Further, a convex portion 56 is formed on the inner peripheral surface of the remaining peripheral band. The projecting portion 56 has the cut off remaining peripheral portion 52 fitted into the recessed strip portion 48 of the inner plug 4 and can be lowered to the lock ring without rotating along the groove of the recessed strip.
A step portion exists on the upper end surface of the sealing band 51, and the remaining peripheral band 52 is connected from the step portion with a weak portion. By pulling the opening knob 53 of the sealing band 51, the structure can be separated from the weak part. A claw-like protrusion 54 is provided on the upper end surface of the sealing band. This protrusion 54 is abutted with a notch-shaped recess 37 provided on the lower edge of the cap in an unused state to display an abutting position B73, and is one that indicates that it is in an unused state. is there.

<Lock ring>
An example of the lock ring 6 is shown in FIG. 5A is a front view, FIG. 5B is a cross-sectional view, and FIG. 5C is a plan view.
The lock ring 6 has a short cylindrical shape and is a member inserted into the lower end side of the neck portion 21 of the container body 2. The convex portion 64 is provided on the inner peripheral surface, and the protruding portion 62 is provided on the upper end surface.
A convex portion 64 is formed on the inner peripheral surface. The convex portion 64 engages with a concave strip portion 48 of the inner plug 4 to be described later and is coupled so as not to rotate. Since the inner stopper 4 is engaged with the container main body, the lock ring is also engaged with the container through the inner stopper. Further, the inner peripheral surface of the lock ring is fitted with an annular recess 44 provided on the lower end side of the inner plug to prevent removal.
A claw-like protrusion 62 is provided on the upper end surface of the lock ring 6. This protrusion 62 is in a state covered with the sealing band 51 in the unused state, and in contact with the concave portion 37 provided in the lower end portion of the hinge cap 3 in the used state, the opening operation is completed. It is a sign that can be visually recognized as being in a usable state. If the lock ring is made of a hard material, a “pachi” sound will be generated at the time of collision, and the completion of the opening operation can also be confirmed acoustically.
Furthermore, by providing the small protrusion 65 on the lower end surface of the lock ring 6 and the small diameter portion 63 on the inner surface, the engagement can be strengthened. The small protrusion 65 provided on the lower end surface side of the lock ring 6 engages with the lower protrusion 23 provided on the container body, and the small diameter portion 63 is fitted with the annular recess 44 provided on the lower edge of the inner plug 4. Strengthen. In the example shown in the figure, the small-diameter portions 63 are provided on the entire inner periphery, but it is sufficient to arrange some small-diameter portions 63 so as to exhibit the retaining function.

<Cap>
The cap is provided with a cutting blade which is covered with an inner plug and cuts and opens the sealing film member when used. As a method for taking out the contents, there is a means for attaching and detaching the cap, but a hinged top cover is suitable. A hinge cap 3 having a hinged top is shown in FIG. 6A is a front view of the cap, and FIG. 6B is a cross-sectional view.
The hinge cap 3 is provided with a body portion 30 that is screwed onto an inner plug 4 having a top lid 34 that opens and closes, a spout 35 and a cutting blade 36.
One end of the top lid 34 is coupled to the upper portion of the trunk portion 30 by a hinge 31. Moreover, it has the stopper 32 which closes the spout 35 in the center part. A knob 33 is provided on the opposite side of the hinge 31.
The trunk portion 30 has a spout 35 at the center of the top surface, and has a small cylindrical cutting blade 36 with a blade portion formed at the tip inside the top surface corresponding to the spout 35. The cylindrical body of the cutting blade 36 is sized to be inserted into an inner cylinder portion 42 of the inner plug 4 described later. The cutting blades 36 are formed in two ridges, and can be opened with a small number of rotations. In this example, the sealing film is not completely separated, and the cutting blade and the downward rotation of the cap accompanying the opening are set so that the sealing film is in a state along the inner peripheral surface of the container neck in the opened state. .
On the inner peripheral surface of the body portion 30, a female screw 39, a convex portion 38 on the lower end side, and a concave portion 37 on the lower edge portion are formed.

The convex part 38 provided in the lower end part has a relationship of interfering with the convex step part 55 provided in the remaining band 52 of the unsealing prevention member. In this example, the convex step portion 55 is configured in two large and small steps, which interfere with the small convex step portion 55a in the unused state, interfere with the large convex step portion 55b in the used state, and have strong coupling in the used state. Realized.
As described above, the recess 37 abuts with the protrusion 54 of the unsealing prevention member 5 in the unused state, and the recess 37 abuts the protrusion 62 of the lock ring 6 in the used state.
When the hinge cap 3 is not in use, the hinge cap 3 is in contact with the upper end of the sealing band 51 of the anti-opening band 5 and the downward movement is restricted. When the sealing band is removed, the hinge cap 3 can be moved downward and rotated. When the screwing is advanced, the cutting blade 36 enters the sealing film to be opened, the lower edge concave portion 37 and the projection 62 are engaged, and the screwing is terminated, the top cover 34 is opened, and the contents Can be taken out. In the unused state, the cap 3 is prevented from being rotated due to the separation operation of the sealing band by the combination of the small convex step portion 55a of the remaining peripheral band and the convex portion 38. Since the cap 3 is weak, if the cap 3 is turned strongly in the loosening direction, the cap can be removed and the state of the sealing film can be confirmed.

<Inner plug>
The inner plug has a double cylindrical structure, is attached to the mouth of the container body, and is sealed with a sealing film when not in use. FIG. 7 shows an example of the inner plug 4. 7A is a front view, FIG. 7B is a side view, FIG. 7C is a cross-sectional view, and FIG. 7D is a plan view.
The inner plug 4 has a double structure including an outer cylinder portion 41 and an inner cylinder portion 42 which are large and small cylinders. The bottom of the inner cylindrical portion is sealed with a sealing film 47. The tip of the neck of the container body is inserted into the gap 45 formed by the double cylinder and is crowned.

On the outer periphery of the outer cylindrical portion 41, a male screw 43, a concave strip portion 48, and an annular concave portion 44 are provided. The concave portion 48 has a groove shape and is provided on the streak upward from the lower end side, and engages with the convex portion 64 of the lock ring 6 and the convex portion 56 of the remaining peripheral portion 52 of the unsealing prevention member 5. To do. The convex portion 56 is guided by the concave portion 48 and the remaining peripheral portion 52 is allowed to move up and down. The annular recess 44 is a portion into which the lock ring 6 is fitted. The lock ring is coupled to the lower end portion of the inner plug in a state in which the lock ring cannot be rotated and is removed.
On the inner periphery of the outer cylinder part 41, vertical ribs 46 and irregularities 49 are formed on the periphery. The vertical rib 46 engages with an intermediate protrusion 24 (described later) provided at the neck of the container main body, and cannot be rotated. As shown in FIG. 7D, when the vertical ribs are formed on inclined surfaces with different gradual and steep slopes, the abutting is strong in the steeply inclined direction and loosely abutted in the slowly inclined direction. For example, in the direction of closing the cap (opening operation), it becomes a strong collision and can be opened without spinning. On the other hand, when the cap is rotated reversely after opening, the cap that is integrated with the inner plug is allowed to loosen by loose contact, which is effective for the retaining function. Moreover, the uneven | corrugated 49 of a peripheral line engages with the convex ring of a lottery part, and fulfill | performs a retaining function. The idling between the inner stopper and the container neck is effective when the connection resistance in the reverse direction between the inner stopper and the container neck is set to be weaker than the connection between the inner surface of the cap and the inner stopper.
The inner cylinder part 42 has a bottomed shape, and the bottom part forms a sealing film 47. The peripheral portion of the sealing film 47 has a structure such as a thin portion that can be easily separated. Between the inner cylinder part 42 and the outer cylinder part 41, the space | gap 45 which inserts the neck part of a container is formed. Note that the sealing film 47 is set so that it is not completely cut off in the opened state but partly remains and takes a posture along the inner surface of the container neck. The sealing film does not drift inside the container, and the clean feeling is not impaired.

<Container body>
The container body includes a housing part and a neck part having an opening at the tip. The container is a bottle or a tube. The contents used are divided into liquids, creams, powders and the like. A hard member is suitable for the neck, and is a material for engaging and fixing the inner plug.
An example of the container body 2 is shown in FIG. (A) is a general view, (b) is a main part view of the neck. The container body 2 includes a neck portion 21 having an upper portion as an opening 22. The base portion of the neck portion 21 is connected to a shoulder portion 28 which is a widened portion of the container.
The neck portion 21 is provided with a lower protrusion 23, an intermediate protrusion 24, and a convex ring 27 from the bottom to the top. Further, a shoulder step portion 26 exists on the upper surface of the shoulder portion 28.

The neck portion 21 is engaged and fixed so as to stop and remove the inner plug 4.
The lower protrusion 23 engages with a small protrusion 65 provided on the lower surface of the lock ring 6, and the lock ring is restricted from rotating with the neck. The lower protrusion 23 is formed with a steep slope in the forward rotation direction and a gentle slope in the reverse rotation direction, so that when the cap 3 is rotated forward, the inner plug strongly abuts at the end portion and becomes loose in the reverse rotation direction. The intermediate protrusions 24 provided in two stages engage with the vertical ribs 46 of the inner plug 4 to restrict the rotation with the inner plug. The intermediate protrusion 24 is also formed with a steep inclination in the forward rotation direction and a gentle inclination in the reverse rotation direction, so that the inner plug adds strength to the coupling resistance in the forward and reverse rotation directions.
The convex ring 27 engages with the concave / convex portion 49 of the inner plug and exhibits a retaining function. Furthermore, by providing the shoulder step portion 26, the lower edge of the lock ring is fitted to improve the integration.

<How to use>
In this example, a cap, an inner stopper, an opening prevention member, and a lock ring are assembled and prepared, and after filling the container body, the assembled cap side member is loaded on the neck to complete an unused container. To do.
FIG. 9 shows an enlarged view of the main portion near the gap 71 of the opened bottle container shown in FIG.
From the lower side, the lower projection 23 provided on the container shoulder 28 and the small projection 65 of the lock ring are engaged, and the convex portion 64 of the lock ring 6 fits into the concave portion 48 of the inner plug, The vertical rib 46 engages with the intermediate protrusion 24 of the container neck 21, the convex portion 56 of the remaining circumferential band 52 fits into the concave portion 48, and the convex step portion 55 of the remaining circumferential band and the convex portion 38 of the cap 3 engage. And the recessed part 37 is provided in the cap lower end. Further, a protrusion 62 is provided at a position facing the recess 37 at the upper end of the lock ring.

In use, as the anti-opening member is provided with the remaining peripheral band which is the upper cylindrical part and the sealing band which is provided with the knob part, the knob part is pulled during the opening operation so that the seal band is cut off. By removing the cap and tightening the cap so as to fill the gap, the sealing film can be cut open and opened. Since the opening operation only needs to move in the direction in which the cap is tightened, the opening operation can be easily understood and an erroneous operation can be avoided. Further, the cap has a sliding resistance with respect to the remaining peripheral portion, so that the cap is prevented from coming off due to the opening of the cap (the operation of separating the sealing band) and can be safely opened.
Since the engagement is made with the cap lower edge and unevenness, a sound is generated at the time of engagement, and the engagement can be confirmed along with the change in the engagement resistance. There is no need to open the cap even once, and it can be opened and used. In the state of use, so that the cap reversely rotates idly, the inner plug is set so that the connection between the neck and the reverse direction is weaker than the connection with the inner surface of the cap.
