Description

  The present invention relates to a hinge cap attached to an inner plug having a dispensing cylinder, and more particularly to a hinge cap with an inner plug having an opening mechanism that does not use a pull ring.

  Conventionally, for food containers that contain dressings, seasonings, etc., in order to keep the inside of the container in a sealed state until opening, the removal wall part defined by the weakening part in the inner plug attached to the container mouth part A cap with an inner plug is widely used in which a partition wall is formed, and a pull ring provided on the removal wall portion is pulled up to tear the removal wall portion to open the spout.

However, a relatively large force is required to pull up the pull ring and break the weakened portion, and it may be difficult for children and the elderly with weak fingertips to open.
Also, depending on how the pull ring is pulled up, the pull ring may be broken in the middle, making it difficult to open.
For this reason, a cap that can be opened not by a pull ring but by a rotation operation of a screwing portion of an overcap is conventionally known as a prior art (see, for example, Patent Document 1).

Next, usage modes and operational effects of this embodiment will be described.
First, in order to attach the hinge cap with the inner stopper of the present embodiment to the container main body 1, the hinge cap W is assembled to the inner stopper A, and then the fitting tube portion 5 of the inner stopper A is applied to the mouth portion 2 and the upper part is attached. Plug from.
In order to assemble the hinge cap W to the inner plug A, as shown in FIG. 6, after the hinge cap W is closed, the circumferential position with the inner plug A is positioned in the state shown in FIG.
The T direction indicated by the arrow in FIG. 8 indicates the direction connecting the shaft center of the inner plug A and the vicinity of the center of the portion where the height of the extraction cylinder 42 is high, that is, the content extraction direction, as shown in FIG. In addition, the assembled state of the circumferential positional relationship between the inner plug A and the hinge cap W in which the claw portion 70 and the parking protrusion 71 correspond to the assembled recess 33 is referred to as a set state.

When the inner peripheral surface of the outer peripheral wall 60 of the cap body B is fitted into the outer peripheral surface of the outer cylinder 10 of the inner plug A and pushed from above at the circumferential position in this set state, the elastic engagement piece 65 becomes a tapered angular surface. The direction is reversed from obliquely downward to obliquely upward while being in sliding contact with 14, and is engaged with the downward stepped portion 16 to prevent separation from the inner plug A.
In the present embodiment, the hinge cap W is pushed into the inner plug A from above and assembled. However, the present invention is not necessarily limited to such a form and can be tightened with a small rotation angle. You may assemble with a screw etc.

Simultaneously with the progress of the assembly process of the inner plug A and the hinge cap W, the engaging portion 83 is fitted into the engaging cylinder 48, and the second engaging protrusion 90 gets over the first engaging protrusion 51 and engages. .
In the set state shown in FIG. 8 (a), the claw portion 70 and the parking protrusion 71 are disposed at a position corresponding to the mounting recess 33, so that the hinge cap W is inserted from above the inner plug A when plugging. At this time, the claw portion 70 is prevented from being damaged even if it is slightly inclined.
Further, in the set state, the ring plate 67 of the base plate portion 61 is fitted into the upward stepped portion 39, and the first centering peripheral surface 38 and the second centering peripheral surface 68 are formed by the hinge cap W and the inner plug A. It works to match the axis of the.

The hinge cap with the inner cap assembled in the set state is such that the mouth portion 2 of the container body 1 is assigned to the fitting groove formed between the outer cylinder 10 and the inner cylinder 11 of the inner plug A, and the hinge cap W is moved upward. , The engagement reduced diameter portion 13 gets over the engagement protrusion 3 and engages, and the plugging process is completed.
In this embodiment, the reinforcing rib 85 of the upper lid C and the lower end of the inner peripheral side of the side peripheral wall 81 are in contact with the annular plate 67, and the lower end of the positioning cylinder portion 62 that is suspended from the annular plate 67 is in contact with the upper wall 12. Therefore, the plugging force applied to the upper portion of the upper lid C is efficiently transmitted to the fitting tube portion 5, and no excessive force is applied.

Further, in the present embodiment, a direction connecting the center and the axis of the hinge D and the knob 87 in the set state indicated by γ-γ in the drawing of FIG. 8 (perpendicular to the rotation axis and the axis of the upper lid C). Direction: hereinafter referred to as “cap direction”) is 90 ° with respect to the pouring direction T. Therefore, as shown in FIG. The rotation radius R of the seal end 89 passing through the contact point with the inner peripheral surface of the extraction cylinder 42 intersects the inner peripheral surface of the extraction cylinder 42 at a tall position so that the upper lid C cannot be opened. .
The angle formed by the cap direction γ-γ and the dispensing direction T in the set state is not necessarily limited to 90 °, and the rotation radius R of the seal end 89 intersects the inner peripheral surface of the dispensing cylinder 42 so that the lid cannot be opened. Depending on the shape of the dispensing tube 42, etc., it can be determined appropriately in the range of about 60 ° to 120 °.

In order to change the hinge cap W from the set state where the lid cannot be opened to the opened state where the lid can be opened, the hinge cap W is rotated in the opening direction indicated by the arrow Y in FIG.
At this time, the claw part 70 and the parking protrusion 71 move away from the assembly recess 33 and move in the direction of the protrusion 31, but the hinge cap W may be rotated in the direction opposite to the opening direction Y by mistake. However, the parking protrusion 71 engages with the anti-reverse wall 32 and prevents rotation in the wrong direction.
Further, since the main body side protection projections 92 (92a, 92b) and the lid side protection projections 93 (93a, 93b) are overlapped to form a gentle curved surface on the opposite side of the hinge D, the user can use the hinge cap W. When the hand is gripped and rotated, the fingers can be prevented from hitting the corner of the hinge D.

When the hinge cap W is rotated in the opening direction Y, as shown in FIG. 9, the second engagement rib 88 is set at a predetermined center angle θ1 from the set position indicated by the two-dot chain line on the circumferential position δ-δ in the figure. Rotating and moving in the circumferential direction ε-ε line in the figure, while the inner plug A is firmly fitted to the mouth portion 2 and does not rotate, the second engagement rib 88 contacts the first engagement rib 50. It becomes the opening start position.
At this time, the cap direction γ1-γ1 of the hinge cap W is rotated by θ1 from the cap direction γ-γ in the set state.
The angle θ1 is about 45 ° in the present embodiment, but is not limited to this.

When the hinge cap W is further rotated in the opening direction Y from the opening start state, the rotational force is transmitted from the second engagement rib 88 to the first engagement rib 50, the engagement cylinder 48, and the thinned weakened portion 45. Finally, the thinned weakened portion 45 breaks and allows further rotation of the hinge cap W.
At this time, the plug body 47 is separated from the inner plug A, but since the first engagement protrusion 51 is engaged with the second engagement protrusion 90, the plug body 47 is supported by the upper lid C. It does not fall into the container.

When the hinge cap W is further rotated in the opening direction Y from the opening start position, the lock claw 73 of the claw portion 70 comes into contact with the overturning inclined surface 37 of the overhanging convex portion 31 and gets over the overhanging convex portion 31 while being elastically deformed. The claw base 72 and the clearance protruding portion 31 pass through the gap between the positioning cylindrical portion 62 and the inner peripheral surface.
Subsequently, the parking protrusion 71 overlaps with the protruding protrusion 31 in the radial direction with a sliding contact with each other or with a minute gap.
Then, at the same time as the claw base 72 comes into contact with the locking projection 30 and the hinge cap W stops rotating, the lock claw 73 is restored by elasticity, and the claw 70 is fitted into the engagement recess 36.
At this time, as shown in FIG. 10, the cap direction γ <b> 2-γ <b> 2 completely coincides with the dispensing direction T, and is in an opened state rotated by an angle θ <b> 2 from the cap direction γ-γ in the set state.
The angle θ2 coincides with the angle 90 ° formed by the cap direction γ−γ in the set state and the dispensing direction T described above.

In this unsealed state, as shown in FIG. 11 (b), the portion where the lower portion of the extraction cylinder 42 is located on the hinge D side and rotates through the contact point between the seal end 89 and the inner peripheral surface of the extraction cylinder 42. The radius R can be opened away from the inner peripheral surface of the dispensing cylinder 42.
The claw portion 70 has a claw base 72 abutting against the base engagement surface 34 of the locking projection 30 to prevent further rotation in the opening direction Y, and the lock claw 73 gets over the claw engagement surface of the projection 31. 35, and the parking protrusion 71 overlaps with the protruding protrusion 31 in the radial direction and prevents deformation of the positioning cylinder portion 62 in the vicinity of the claw portion 70, so that rotation in the direction opposite to the opening direction Y is prevented and the opening state Can be maintained.

As shown in FIG. 12, when the upper lid C is opened in the opened state, the plug body 47 is supported by the upper lid by the engaging portion 83, so that it is separated from the inner plug A together with the upper lid C, and the inner periphery of the dispensing cylinder 42 A spout is opened at.
As described above, the hinge cap with the middle stopper of the present embodiment enables the opening and opening of the lid with a single operation of rotating the hinge cap W in the opening direction Y from the set state immediately after the stopper is plugged. It is possible to start using the container with a simple operation.

As shown in FIGS. 3 to 5, the hinge cap with an inner stopper of the present embodiment is a container body 1 that can be easily operated when the container is discarded after being used by the separation mechanism provided at the lower part of the outer cylinder 10. Can be separated, separated and discarded.
First, when a finger is put on the hook recess 20 of the longitudinal cutting portion 19 and the gripping portion 18 is pulled forward, the longitudinal cutting portion 19 is broken and the gripping portion 18 is expanded outward.
When the gripping recess 21 is gripped by a finger and the gripping portion 18 is further pulled, the thin-walled start portion 22 provided adjacent to the end 17 a of the gap 17 is broken and is formed thin by the notch recess 23. The fracture proceeds to the circumferential cut portion 24 that has been made.

  When the circumferential cut portion 24 breaks, the engagement of the engagement reduced diameter portion 13 with the engagement protrusion 3 is released. Therefore, when the breakage proceeds to the vicinity of the break end portion 23a, the engagement reduced diameter portion 13 is released. When the restraint on the mouth portion 2 due to is released and the gripping portion 18 is pulled up, the inner stopper A can be detached from the container body 1 and separated and discarded.

Next, a description will be given of a second embodiment in which the configuration of the stopper and the upper lid is changed in accordance with the change of the configuration of the dispensing cylinder.
In the following, the same components as those in the first embodiment are denoted by the same reference numerals, and differences will be mainly described.

The present embodiment is good when applied to a hinge cap with an inner plug having a small-diameter nozzle-like dispensing tube attached to a squeeze container or the like. As shown in FIGS. The pouring tube portion 7 is erected in the center of a base portion 141 connected to the tube wall portion 6 so that the pouring tube 142 has a chimney shape with a relatively small diameter.
A plug body 147 is integrally connected to the upper end of the dispensing cylinder 142 through a thinned weakened portion 145 that is continuous with the inner peripheral surface of the dispensing cylinder 142.

As shown in FIG. 15, in the plug 147, a bottom wall 149 connected to the thinned portion 145 seals the spout together with the thinned portion 145, and a cylindrical engagement tube 148 is formed on the outer peripheral edge of the bottom wall 149. Is erected.
A plurality of first engaging ribs 150 whose outer diameter at the top is slightly smaller than the outer periphery of the extraction tube 142 are provided on the outer periphery of the engagement tube 148. The mating protrusion 151 is provided in a ring shape.
As shown in FIG. 15B, 24 first engagement ribs 150 of this embodiment are formed in a knurled shape in the vertical direction (axial direction), and the cross-sectional shape thereof is substantially triangular. ing.
A tapered portion 150 a is formed at the upper end of the first engagement rib 150 in order to facilitate fitting with a second engagement rib 188 described later.
Note that the number of the first engagement ribs 150 is not necessarily 24, and can be appropriately determined as necessary, and may be 4 as in the first embodiment.

The sealing cylinder portion 182 suspended from the back surface of the top wall 80 of the upper cover C of the hinge cap W has a sealing end portion 189 that fits and seals with the outer peripheral surface of the chimney-shaped extraction cylinder 142 at the inner peripheral lower end portion. A plurality of second engagement ribs 188 that are formed and are engaged with the first engagement ribs 150 project inwardly above the seal end 189.
Similarly to the first engagement rib 150, 24 second engagement ribs 188 are equally formed in a knurled shape in the longitudinal direction (axial direction). Similarly, the number can be determined as appropriate.
Moreover, although the taper part 188a is formed in the lower end part of the 2nd engagement rib 188, both the taper parts 150a and 188a are not necessarily required, and only one of them may be sufficient.

Since the position of the seal portion between the seal end portion 189 and the tip of the extraction tube 142 is high, the hinge D is also provided at a relatively high position, and the lower end of the side peripheral wall 181 is high on the hinge D side, and on the opposite side of the hinge D From the circumferential position where the central angle on the hinge D side is about 90 ° to the circumferential position where the central angle is about 180 ° (intermediate circumferential position between the hinge D and the opposite side of the hinge D). Inclined with reduced height.
On the inner peripheral side of the side peripheral wall 181, a diameter-reduced inclined surface 101 that decreases inward from the lower end, and a locking step portion that forms a downward stepped portion from the upper end of the reduced-diameter inclined surface 101 through the engaging concave surface 102. 103 are formed so as to be higher on the hinge D side and lower on the opposite side of the hinge D in parallel with the lower end of the side peripheral wall 181.
At the upper end of the reduced diameter inclined surface 101, that is, at the boundary between the reduced diameter inclined surface 101 and the locking concave surface 102, auxiliary ridges 104 project in two predetermined circumferential ranges on both sides centered on the opposite side of the hinge D. Has been.
In addition, a reinforcing cylinder portion 105 that extends from the back surface of the top wall 80 to the upper surface of the ring plate 167 of the substrate portion 161 is provided inside the side peripheral wall 181.

On the outer peripheral edge of the ring body 167 of the cap body B opposite to the hinge D, a locking bulge portion 107 that fits into the locking concave surface 102 is projected, and the locking bulging portion 107 is formed on the locking concave surface 102. In response to the hinge D, the hinge D rises with the outer peripheral wall 160 from the peripheral position with a central angle of about 180 ° on the hinge D side, and gradually increases to the peripheral position with the central angle of about 90 ° on the hinge D side. It is formed at a certain high position on the D side. The ring plate 167 is integrated with the protruding outer peripheral wall 160 on the hinge D side.
When the lid is closed, the auxiliary protrusion 104 climbs over the locking bulging portion 107 and engages with the lower portion of the locking bulging portion 107 to reliably maintain the closed state.
On the inner periphery near the lower end of the outer peripheral wall 160 of the cap body B, an engaging protrusion 108 that engages with the downward step portion 16 of the inner plug A protrudes.
Other configurations such as a lock mechanism are the same as those in the first embodiment.

In this embodiment, the lower end of the side peripheral wall 181 and the upper end of the outer peripheral wall 160 are formed high on the hinge D side and low on the opposite side of the hinge D, and the sealing performance between the seal end 189 and the tip of the dispensing cylinder 142 is formed. The upper lid C is easy to grip while suppressing the overall height of the hinge cap W and is excellent in operability and appearance. However, the lower end of the side peripheral wall 181 and the outer peripheral wall 160 are not necessarily in this way. There is no need to provide an inclined portion at the upper end, and the height may be constant.
Further, the circumferential range of the inclined portion in which the heights of the lower end of the side peripheral wall 181 and the upper end of the outer peripheral wall 160 change is not limited to this example, and can be set as appropriate.

Next, usage modes and operational effects of this embodiment will be described.
First, the hinge cap W to assemble the inside plug A, the circumferential positional relationship between the inner plug A hinge cap W, to the set state (the claw portion 70 and the Chutome projection 71 and is assembled the recess 33 shown in FIG. 8 It is the same as in the first embodiment that it is pushed in from the top according to the corresponding circumferential position). However, in this embodiment, the engagement protrusion 108 protruding from the lower inner periphery of the outer peripheral wall 160 is a taper of the outer cylinder 10. It passes over the corner surface 14 while sliding, and engages with the downward step 16.
In the hinge cap W in the closed state, the lower portion of the locking bulge portion 107 is engaged with the upper portion of the auxiliary protrusion 104, so that the closed state is reliably maintained.
The engaging protrusion 108 can be reduced in cost by a simple structure, but it is of course possible to employ an engaging piece 65 that has elasticity and is reversed and engaged as in the first embodiment.

When the hinge cap W is assembled, the first engagement rib 150 and the second engagement rib 188 are each tapered, even if the first engagement rib 150 and the second engagement rib 188 come into contact with each other and do not mesh well. 150a and the tapered portion 188a are formed, and as a result of slight rotation in the circumferential direction, as shown in FIG. 15 (b), the multiple first engaging ribs 150 and second engaging ribs 188 mesh with each other. Insert.
It is the same as in the first embodiment that the hinge cap W assembled in the set state is plugged and the inner plug A is fitted and fixed to the mouth portion 2 of the container body 1. The plug force is transmitted to the fitting cylinder portion 5 efficiently and stably through not only the side peripheral wall 181 but also the reinforcing cylinder portion 105.

In order to unplug and open the plug 147 from this set state, the hinge cap W is rotated in the opening direction Y shown in FIG. 8 as in the first embodiment.
Since the first engaging ribs 150 and the second engaging ribs 188 are already closely meshed with each other, the rotational force is immediately transmitted to the plug 147 and the thinned portion 145 is broken.
Further, when the hinge cap W is rotated, the claw portion 70 is fitted into the engagement recess 36 as in the first embodiment, and the hinge cap W and the inner plug A become non-rotatable and are fixed to each other. Opened.

In this embodiment, the angle θ1 for rotating the hinge cap W from the set state to the unsealing start state is almost 0 °, and the dispensing tube 142 has a tip outer periphery on the seal end 189 on the tip inner periphery of the sealed tube 182. Since the circumferential position that fits in the circumferential direction at the same height and is in the opened state is not selected, the angle θ2 for rotating the hinge cap W from the set state to the opened state can be significantly smaller than that in the first embodiment.
Further, the diameter of the engagement position between the first engagement rib 150 and the second engagement rib 188 is smaller than the first embodiment with respect to the outer diameter of the hinge cap W, and the opening operation can be performed with a small rotational force. The opening operation is simpler.
In the first embodiment, the height of the dispensing cylinder 42 is varied in the circumferential direction to create a state in which the lid cannot be opened before opening. However, in the case of the present embodiment as well, various known unauthorized opening prevention means are used. Etc. are desirable.

If the upper lid C is opened from this unsealed state, the plug body 147 separated from the inner plug A has the first engagement protrusion 151 engaged with the second engagement protrusion 90 of the engagement portion 83, so that the upper cover C It is held and removed from the upper part of the dispensing cylinder 142, and the spout opens.
At the time of opening the lid, it is necessary to release the engagement between the auxiliary protrusion 104 and the locking bulging portion 107, but the protruding height of the locking bulging portion 107 is very small, and it is on the side opposite to the hinge of the upper lid C. Since the height is high, it can be easily released because it is easy to grip.

Next, a description will be given of a third embodiment in which the configuration of the plug body is changed and the configuration of the upper lid is changed in the second embodiment.
In the following, the same components as those in the first embodiment and the second embodiment are denoted by the same reference numerals, and the description will focus on the differences.

As shown in FIGS. 16 and 17, the plug body 247 is integrally connected to the upper end of the dispensing tube 142 via the thinned portion 145 in the same manner as the second embodiment.
The plug body 247 of this embodiment has a plurality of first engagement ribs 250 formed on the inner periphery, and a first engagement protrusion 251 protruding from the upper end of the outer periphery.
A cylindrical boss 201 is suspended from the center of the back surface of the top wall 80, and a plurality of second engagement ribs 288 that can engage with the first engagement rib 250 are provided on the outer periphery of the boss 201, A central core portion 202 erected on the bottom wall 249 of the plug body 247 is rotatably fitted to the inner peripheral side of the boss portion 201.
In this embodiment, the boss portion 201 is cylindrical, but it is not necessarily cylindrical, and the central core portion 202 may not be provided.

As shown in FIGS. 17B and 18, the first engagement ribs 250 and the second engagement ribs 288 are provided equally at four locations in the circumferential direction, and each abutment surface 250 b that engages with each other. 288b is formed in the radial direction passing through the axis O.
In the set state shown in FIG. 17B, the angle formed by the contact surfaces 250b and 288b facing each other is θ1.
A second engagement protrusion 290 that can be engaged with the first engagement protrusion 251 is provided on the sealing cylinder portion 282 so as to protrude above the seal end 289 formed at the inner circumferential tip.

Next, usage modes and operational effects of this embodiment will be described.
First, in order to assemble the hinge cap W to the inner plug A, the hinge cap W is closed, and the circumferential positional relationship with the inner plug A is such that the claw portion 70 and the parking projection 71 correspond to the mounting recess 33. The pushing in the state is the same as in the first and second embodiments, and the point that the engaging projection 108 engages with the downward stepped portion 16 to prevent detachment from the inner plug A is the same as in the second embodiment.
At this time, the second engagement protrusion 290 of the sealing cylinder 282 is fitted over the outer periphery of the engagement cylinder 248 over the first engagement protrusion 251 of the plug 247.

As shown in FIG. 18, when the hinge cap W assembled in the set state is rotated by θ1 in the opening direction indicated by the arrow Y in the figure, the contact surface 288b of the second engagement rib 288 is It moves from the set position on the circumferential position δ-δ indicated by the two-dot chain line to the circumferential position ε-ε indicated by the solid line, and enters an opening start state where it comes into contact with the contact surface 250b of the plug 247.
When the hinge cap W is further rotated from the opening start state, the thinned portion 145 is broken, and when the hinge cap W is further rotated from the set position to the central angle θ2, the claw portion 70 is fitted into the engagement recess 36. The unsealed unsealed state is the same as in the first embodiment.

  Also in the case of the present embodiment, as in the second embodiment, since the dispensing tube 142 does not select the circumferential position where the unsealed state is set, the angle θ2 for rotating the hinge cap W to open is smaller than that of the first embodiment. Since the first engagement rib 250 is formed on the inner peripheral side of the engagement cylinder 248, the diameter of the engagement position where the first engagement rib 250 and the second engagement rib 288 mesh with each other is Since it becomes smaller than an Example and the force required for opening becomes still smaller, opening operation becomes simpler.

  The hinge cap with an inner cap of the present invention can be opened simply by rotating the hinge cap in one direction, and the use of the container can be started by fixing the hinge cap in the dispensing direction. It does not require a large force to open the cap like a cap, and it does not require troublesome opening and opening operations, so it can be used easily by children and the elderly, and can be used widely as a cap for containers. It is.
