At the same time, in order to prevent unintentional opening in an unused state, there are many bottle cap structures that are accompanied by an improper opening mechanism.

For example, Patent Document 1 (Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. Hei. No. Hei.

These conventional examples have no particular effect on the consideration of the broken sealing material falling into the container or remaining after cutting.

Patent Document 3, which was previously proposed by the applicant of the present application, discloses an unsealing structure in which an outer cap 109 provided with an outer cover 110 is provided with a guiding cylinder 120 which is inclined to form a slit, and by the leading end of the guiding cylinder 120 Since the sealing material 108 is broken, the sealing material is not required to be removed from the outer cap, and there is no risk of contamination by bacteria or finger contamination, and the container can be kept closed after use. In the drawings 11, FIG. 12, FIG. 13, and FIG. 14, the prior invention disclosed in Patent Document 3 is described. Fig. 11 is a schematic view of the entire container, Fig. 12 is a cross-sectional view of the head in an unused state, Fig. 13 is a cross-sectional view showing a state in which the endless belt portion is removed, and Fig. 14 is a view showing a state of use.

In this conventional example, the cosmetic liquid is injected into the container 101, the inner plug 108 is covered and fixed in the opening 102, and the container 101 is sealed, and the outer cap 109 is generally covered and fixed as described above. Keep it in this state until the consumer. When the cosmetic liquid is used, if the one end portion 108g of the endless belt portion 108f is elongated, as shown in Fig. 13, the endless belt portion 108f is cut from the lower end of the outer peripheral wall 108a of the inner plug 108, and the endless belt is cut. The portion 108f peels off. Therefore, as shown in FIG. 14, when the outer cap 109 is pressed from above, the outer cap 109 is deflected downward, and the outer peripheral wall 110c of the cap 110 slides on the outer periphery of the outer peripheral wall 108a of the inner plug 108 and the annular projection of the opening 101 of the container 101. On the outer periphery of the portion 105, the bottom surface of the surface plate 110b of the body cap 110 abuts against the upper end of the outer peripheral wall 108a and the inner peripheral wall 108b of the inner plug 108.

At this time, the guiding cylinder 112 of the main body cap 110 is lowered inside the inner peripheral wall 108b of the inner plug 108, and the inner plug 108 is pierced according to the front end portion formed by the lowermost end portion 112b of the guiding cylinder 112 and the vertical end edge 112c. The outer peripheral edge of the thin layer of the shielding plate 108c gradually spreads and cuts along the inclined lower end edge of the guiding cylinder 112 as the guiding cylinder 112 descends. Next, as shown in FIG. 14, the shielding plate 108c is cut out from the inner peripheral wall 108b. At this time, the inner circumferential annular projection 110d of the outer peripheral wall 110c of the outer cap 109 of the outer cap 109 is fitted into the lower annular recess 107 below the annular projection 105 of the outer peripheral wall 103 of the container 101, so that the outer cap 109 is fixed.

Thereby, the inner plug 108 of the opening 101 of the container 101 is opened. Further, to remove the cosmetic liquid in the container 101, the outer cover 111 of the outer bottle cap 109 is rotated around the hinge 111b. Thereby, the small hole 110a of the surface plate 110b of the main bottle cap 110 is opened, and if the container 101 is tilted, the cosmetic liquid is injected from the small hole 110a through the guiding cylinder 112. If the outer cover 111 is again covered by the body cap 110, the protrusion 111a of the outer cover 111 is fitted into the small hole 110a of the body cap 110, and the container 101 is sealed.

This design is a circumferential arrangement relationship, the size and shape of the blade, and the like.

The case of the arrangement on the circumference is a non-point symmetrical configuration, and the case of the symmetrical arrangement is to change the height of the front end of the blade, and the case of the shape of the mountain blade is to change the taper angle or the like. Moreover, it can be realized by combining the above aspects.

The cutting operation can also be performed arbitrarily, but by limiting the end of the cutting, the residue can be surely cut. For example, the inner cap and the cap body are screwed together by the end point of the screwing and the cutting action at the same time point.

In terms of material, the container body and the cap can be made of synthetic resin or metal. Each component will be described in detail below.

1. All composition

The present invention is a bottle cap having a sealing film opening structure. This cap is a cover bottle container. The cap is composed of an inner cap having a sealing member and a cap body covering the inner cap. Further, in the unused state, an unsealing prevention ring for preventing improper opening can be applied as needed.

2. Cap

The cap is composed of an inner cap and a cap body. The unsealing prevention ring can be inserted in an unused state as needed.

2-1. The cap inside the inner cap has an outflow hole after sealing, covering the neck of the bottle container. In the case of covering the bottle neck, it is preferable to form a double-layered cylindrical shape and hold the bottle neck. The inner cylinder forms an outflow opening that seals the bottom to form a closure element. The inner cap is preferably not rotated after being placed in the bottle. The connection structure with the bottle is defined by the configuration of the bottle, but it is necessary to have a pull-out prevention function and a rotation prevention function in the longitudinal direction. For example, if a dot-like unevenness is combined, two functions can be realized. Further, by combining the annular convex portion and the concave portion, the extraction can be restricted, and if the convex portion and the concave portion are combined in the longitudinal direction, the rotation in the circumferential direction can be restricted. A plurality of ribs are provided under the neck of the bottle, and a plurality of ribs are also provided on the front end side of the inner bottle cap, and the rotation in the circumferential direction can be prevented by inserting and inserting each other at the time of attachment.

The sealing film of the sealing member can be bent into a disk shape. The degree of bending is preferably the same as the curvature of the inner circumference of the neck of the bottle so that the inner surface is in stable contact with the neck of the bottle in the unsealed state.

2-2. Cap Body The cap body is a cap that covers the inner cap and has two blades that are used to open the cap of the cap.

When the inner cap has a cylindrical outflow hole, it is preferable that the blade as the unsealing sealing member is provided with two blades at the tip end of the cylinder which is slidably attached to the cylinder and is open below.

The two blades are formed into a sealing film that can be cut along the inner edge, substantially over the entire circumference, and a portion of the cut can be left as a web. For example, non-point-symmetric configurations, different-sized mountain-shaped blades, mountain-shaped blades with inconsistent degrees of inclination, blades with inconsistent heights at the front end, and the like. The unsealing action is performed by turning. The rotary cutting of the two blades enables the cutting path portion of each blade to not be repeated. Since the rotation range is limited, the correct cutting trajectory can be realized, and the connecting piece is surely left. If two joint pieces are made, the sealing element cannot be fully opened, and there is a hindrance to the smooth pouring out. If it is completely cut, there will be fragments of the sealing element floating in the body of the bottled container, and there is a problem that the hole is caught and the flow is blocked. When the bottle container is transparent, it gives the impression of being mixed with impurities. Especially in cosmetics and beverages, it can cause poor use.

The contact portion of the blade which is stopped by contact with the remaining connecting piece can maintain the opening piece in a predetermined posture if the opening piece is pressed downward. For example, if the cutting end portion is an inclined surface facing downward, pressure can be applied downward by contact. At the same time, the blade portion is formed to end the blade portion at the end of the cutting end, and if the cylinder of the attached blade is further penetrated from the end of the cutting, the joint caused by the outer peripheral surface of the cylinder to which the blade is attached is pressed, and the opening of the sealing piece can be applied. The force underneath. However, because if the entry is too deep, the link piece may be broken. It is important to note that the degree of entry is not broken.

As a method of restricting the rotation of the cylindrical body provided with the two blades, the inner cap and the cap body can be screwed together, and the connecting piece at one end remains at the end of the screwing.

Since two blades are placed on the same circumference to cut and form a web, in the two possible cutting start points and cut end points, the cutting end point will cross the other cutting start point, and a joint piece will be produced. The cut sound, so you can confirm the end of the opening operation.

The form of the formation of the two blades and the rotation restriction of the opening operation are as follows.

(1) A bottle cap with a sealing film opening mechanism, which is provided with a cap of a cylindrical body for sealing a film with a blade, and two blades are provided, and the opening distances caused by the two blades are different, and after the opening operation A residual portion of the cut remains in the seal film.

(2) The unsealing distance caused by the two blades can be different because the cylindrical edges are not point-symmetric and/or the heights of the front ends of the blades are different.

When non-point symmetry, that is, when the blades on the circumference are arranged at different intervals, when the two blades start cutting at the same time, the difference between the long interval and the short interval at the time when the length corresponding to the shorter interval is cut is cut. Some will remain as a link.

Further, when the heights of the tips of the two blades are different, when the cutting operation is performed by rotating the blades, a time difference occurs between the cutting start times of the two blades, and the length of the time difference portion can be left as a connecting piece.

(3) A bottle cap having a cap body for sealing a discharge hole, and a cylindrical body having two protruding blades at a front end of the cylinder and capable of advancing back and forth in the injection hole , set on the inside top surface.

(4) An example of a specific form of the non-point symmetrical configuration can be specified as follows. A bottle cap is composed of an inner cap provided with a sealing film and a cap body that screwes the inner cap, and has two blades that break the sealing film by rotating the cap body in the forward direction, and the two blades are The positional relationship in the circumferential direction in which the tip end of one blade is 0° around the axis of the cylindrical body and the relationship between the fracture and rotation are set in the following manner. The unsealed state of the sealing film is formed into a joint portion after the breaking operation.

The position of one blade A is 0°, the position of the other blade B is θ b>180°, and the fracture rotation angle of the blade A is θ cut<θ b. The fracture rotation angle of the blade A is θ cut+θ b>360°.

(5) In addition, by standardizing the screwing relationship, it is possible to limit the remaining residual piece of the cutting. For example, a bottle cap is composed of an inner cap provided with a sealing film and a cap body that screwes the inner cap, and has two blades that break the sealing film by rotating the cap body in the forward direction; The cover is a cylindrical shape having a male thread on the outer circumference, and is provided with a discharge hole formed by a short-diameter, bottomed cylindrical body having a bottom formed on the inner side, and the bottom is a sealing film; the cap body Is a cylindrical cover body having an inner diameter formed by the female thread, and the female thread is a male thread screwed into the inner cap, and the inner top surface of the cover body is formed to be inscribed in the above-mentioned injection hole, and can be front and rear a cylindrical body with a blade that advances and retreats, the blade is formed in two, and the interval between the protruding blades is a large interval of a large interval angle, and a short interval of a small interval angle is not point-symmetric; the cap body is provided The limit of the tip end of the protruding blade from the starting position of the sealing film of the injection hole of the broken inner cap is set to be larger than the small interval angle and smaller than the above-mentioned large interval angle, thereby setting the inner cap and the cap body The screwing relationship.

Further, in this case, the cylindrical blade for sealing the film with two blades is formed so that the blade portion ends at the end of the cutting end, whereby the opening sheet can be kept pressed downward at the end of the cutting. Further, if the screwing is continued from the end point of the blade portion to the range not exceeding the length of the joint portion, since the joint piece is pressed according to the outer side surface of the cylindrical blade, the downward posture of the open piece can be more stabilized.

2-3. Hinged Caps A cap with a hinge can be placed on the front end side of the cap body. After opening, the contents can be marked by switching the hinged cap. It is easy to use and hygienic for the use of a small drop after opening. For example, it is suitable for containers for cosmetics.

2-4. Unsealing Prevention The ring opening prevention ring is a structure indicating an unused state, and it is preferably provided separately from the cap body or the inner cap for another individual. An improper unsealing method indicating an unused state is generally a method of connecting a cap and a cap body in a strip shape (for example, Patent Document 3). The applicant of the present invention, as disclosed in Japanese Laid-Open Patent Publication No. Hei. No. 2006-193202, proposes a new method of forming an annular unsealing preventing element by another individual.

3. Bottle container body

Suitable for bottles that can visually recognize residual amounts and have transparency. From the viewpoint of transparency, it can be made of synthetic resin or glass. For example, cosmetic containers and the like.

In the unused state, the inner cap 3, the unsealing preventing ring 5, and the cap body 4 are sequentially covered in the neck portion 21 of the container body 2. The neck front end of the bottle container enters the gap 35, and the annular convex portion 22 provided on the neck of the bottle container body 2 is press-fitted to the annular recessed portion 34 of the inner bottle cap to prevent the inner cap 3 from coming off. The longitudinal ribs 23 formed on the neck base of the bottle container are snapped with the longitudinal ribs 36 provided on the inner side surface of the base of the inner bottle cap to control the rotation in the circumferential direction. Further, the male thread 33 of the inner cap is screwed with the female thread 42 of the cap body. The thread is a double thread, and even if the number of rotations is small, a strong and stable screw can be achieved. In order to maintain the unused state, the opening preventing ring 5 is inserted into the lower portion of the cap body to block the entry of the screw, and the cylindrical blade 70 is prevented from falling to come into contact with the sealing film 7.

In the state of use, the cap body and the unsealing prevention ring are temporarily removed together, and only the cap body is reinstalled and continues to be screwed to the end point, thereby cutting the cylindrical blade around the sealing film 7, leaving only The lower piece 79 is joined to form an unsealed state. The hinged cap 6 can then be opened to remove the contents for use.

In the present embodiment, the sealing film 7 has a disk shape which is bent downward toward Δd. In Fig. 1(b), this Δd forms a curvature which is in contact with the neck 21 of the container body. Due to such a state, the cut sealing film can maintain a stable posture and maintain the use state after the opening.

The configuration of the cap body will be described with reference to Figs. 2 to 4 . 2 is a cross-sectional view of the cap body with a hinge, FIG. 3 is an external view of the cap body, and FIG. 4 is a view of the state of the blade viewed from the bottom.

The cap body 4 is provided with a cylindrical portion 41 that covers the inner cap and forms the female thread 42, and a hinged cap 6 is provided on the top of the cylindrical portion 41. A cylindrical blade 70 having a blade on the front end side is provided at the center portion. The base side of this cylindrical blade is the injection port 65. A snap protrusion 47 is provided on the inner side of the base portion of the cylindrical portion 41 so as to be engaged with the snap recess 37 provided at the bottom end portion of the inner cap so that the two ends are not easily loosened at the end of the screwing. .

The cylindrical blade 70 is provided with two blades of a blade A71 and a blade B72, and has a shape of a mountain peak when viewed from the side. The top portion is provided with a flat portion 78, a blade tip portion 73 which is straightly formed in front of the blade, and a blade edge which continues the tip end portion. The inclined surface 74 has a flat portion 75. The blade rear end is connected to the flat portion via a rear bevel 77. The two blades are composed of a large separation angle of 210° and a small separation angle of 150°. The opening operation will be described later, but the connecting piece having a cutting angle of 150° and 40° is not cut and remains. Since the blade is provided with a flat portion of 20° at the top, if a part of the blade front end inclined surface 74 that penetrates the sealing film during cutting is calculated, a total of 170° is cut, so that the residual angle of the uncut is 40 degrees.

The configuration of the inner cap will be described with reference to Figs. 5 and 6 . Figure 5 is a cross-sectional view of the inner cap, and Figure 6 is an external view of the inner cap. The inner cap is generally cylindrical in shape and has a double structure with a small diameter cylinder on the inner side. The bottom of the small diameter cylinder is sealed with a sealing film. The neck end of the container body is inserted into the gap portion formed by the double cylinder to cover the structure.

More specifically, the inner cap 3 is formed by double combining the outer tubular portion 31 composed of the male screw 33 and the inner tubular portion 32 sealed by the sealing film 7, and has a gap 35 due to the two portions. The outer base portion of the outer tubular portion 31 is provided with a snap recess 37 that snaps with the projection of the cap body or the opening preventing ring. The snap recess 37 is located between the expansion portions having a tapered shape on both sides, and the projection of the cap body or the like is hooked across the expansion portion to form a configuration in which the covering position is terminated. Further, the expansion portion is small in the direction of rotation in the direction of the user and large in the front direction, and can also function to prevent rotation and to resist rotation in the slack direction. The longitudinal ribs 36, 36.. on the inner side of the outer tubular portion 31 form an annular recessed portion 34, and are engaged with the longitudinal ribs 23 and the annular convex portion 22 respectively provided on the neck portion of the container body to prevent extraction and rotation. Coverage relationship.

It can be made of a transparent synthetic resin, and is made of a blow molding using a material such as PET. Figure 7 is a side elevational view of the container body 2 having a neck portion 21 formed by tightening the shoulder portion, the neck portion having an annular projection 22 and a longitudinal rib 23.

The opening prevention ring 5 is as shown in FIG. It has a layered cylindrical shape and is mounted on the inner cap, and the upper small portion and the caliber portion are attached to the base of the cap body. In the installed state, it can indicate the unused state and also prevent the contact between the sealing film and the blade. Although the illustration of the detail is omitted, in order to limit the snap position of the inner cap and the cap body, a recess for the snap and a convex portion are provided.

Regarding the opening operation, please refer to FIG. Fig. 10 is a view showing the positional relationship of the cylindrical blade 70 in the state of the inner view of the inner cap. The sealing film 7 provided in the inner cylindrical portion 32 of the inner cap is shown at the center. The state of the two blades A, B71, and 72 in the inner tubular portion 32 is a longitudinal sectional view mark. Fig. 10 (a) is a view showing an unused state after the opening of the opening preventing ring, and Fig. 10 (b) is a view showing a state in which the opening preventing ring is removed, and the blades A, B71, and 72 start the cutting of the sealing film 7, and Fig. 10 (c) It is a state in which the cutting is completed after the connection piece 79 is left. The shape of the blade A71 and the blade B72 formed at the front end of the cylindrical blade 70 are as described above, and are the same shape of a mountain.

Fig. 10 (a) is a view showing the positional relationship of each element under a circular coordinate axis having a rear end of the flat portion 78 of the blade A71 of 0°. The rear end of the flat portion 78 of the blade B is disposed at 210°, and the respective flat portions have a length of 20°, and the base portion of the blade edge slope 74 at the bottom of the blade and the base of the rear slope 77 have a length of 90°. From the longitudinal section of view, the flat portion 78 of the blade and the sealing film 7 are in a non-contact state.

Fig. 10 (b) shows a state in which the opening of the opening preventing ring is removed and the position of the flat portion of the two blades is cut through the sealing film and the starting point of the cutting is performed from the position of Fig. 1 (a) at 45°. The rear end of the flat portion 78 of the blade B is at 255°.

Fig. 10 (c) shows a state in which the other is rotated by 135° and the cutting is completed. The rear end of the flat portion 78 of the blade A71 is located at 180°. The rear end of the flat portion 78 of the blade B is 30°. In the longitudinal section, the blade A71 is in the state of 83a, and the blade front end inclined surface 74 is formed in a state in which the sealing film 7 is pierced, and the front bevel portion is a portion of 15° and a portion of the plane portion of 20°, and the portion formed by the blade A71 is formed by the blade A71. The angle of the cut, the coordinate axis is 215°. Therefore, with respect to the rear end 255 of the flat portion 78 of the blade B of Fig. 10(b), the phase difference portion 40 is cut and left, corresponding to the portion where the connecting piece 79 is formed.

The above structure is used to enable a series of screwing rotations to be achieved within 360°. The opening prevention ring portion is 180°, and the cutting rotation takes the clearance into 180°. The correct control of such a small rotation angle is achieved by the screwing structure of the double thread.

On the other hand, the blade B72 at the end of the cutting is in the state of 83b in the longitudinal section, and the blade edge 73 of the plane blade B72 is 50°. Therefore, this portion becomes cut by the cutting position of the blade A71 by 45°. Even if the expansion of the synthetic resin is considered, the blade leading end slanting surface 74 of the blade B72 enters the same manner as the blade A, and exceeds the sealing film level by 15°, so that it is actually cut.

If this embodiment is added to the fourth item of the patent range, it is considered as follows. Since in the present embodiment, the top of the blade completes the substantial cutting function of the inclined surface of the plane portion or the mountain shape, it is necessary to consider the applicable relationship in consideration of this portion. In the case of a rod-like blade like a needle, it is not necessary to consider such a relationship.

(1) Position of one blade A = 0°: 45° at the rear end position of the flat portion 78 of the blade A71 in Fig. 10(b) (The invention concept described in the patent application is because the blade is estimated to be a sealing film The arrangement relationship is equivalent to 45° here. (2) The position of the other blade B is θ b>180°: at the rear end position of the plane portion 78 of the blade B72 in FIG. 10(a) is 210° (here is equivalent thereto). 210° at a large interval angle) (3) The fracture rotation angle θ cut<θ b of the blade A on one side: the angle of the cutting of the blade A by the blade A71 170° (4) The rotation angle θ cut+θ b> 360°: an angle of 170° cut by the blade A71 + 210° of the rear end position of the flat portion 78 of the blade B72 of Fig. 10(a)

Because the end of the cutting of the blade B72, a cracking sound will occur, so the user can confirm with the ear that the sealing film is actually opened, and no need for unnecessary turning action can be reassuring. Because the blade is inserted due to the screwing, the opening operation can be completed with a small force compared with the force directly inserted.

The remaining connecting piece 79 is biased toward the back side by the flat portion 75 of the blade A71, and the posture is stabilized. Even if the hinged bottle cap is opened and the pouring operation such as shaking and pouring is performed, the sealing film does not return, and the sealing film can be smoothly Perform a note-out operation.

The curved sealing film can be attached to the neck of the container body, and the posture of the sealing film after the opening of the plug can be stably maintained, thereby preventing an obstacle from being used.

The cap of the present embodiment is prepared by integrally combining the inner cap and the unsealing preventing ring with the cap body, and can be covered by press-bonding the neck of the bottle container body filled with the contents. Therefore, the bottling step can be simplified.
