Description

Cap unit and capped container

Technical Field

The invention relates to a cover unit and a container with a cover.

Background

Conventionally, a beverage container having a cap unit (plug body) attached to a mouth-neck portion of a container body having an upper opening is known as a container with a cap (see, for example, the following cited document 1).

For example, the cover unit described in the following cited document 1 includes: a lid body which closes an upper opening of the container body and is provided with a liquid inlet serving as a drinking spout or a pouring spout at an upper portion thereof; a lid body which is rotatably attached to the lid main body via a hinge portion and which opens and closes the liquid passage opening in a state in which a biasing member provided at the hinge portion biases the liquid passage opening in a direction in which the liquid passage opening is opened; and a cover locking mechanism for fixing the cover body at a position for closing the liquid passage opening against the urging force of the urging member.

In a beverage container (container with a lid) provided with such a lid unit, the lid body is rotated by the biasing force of the biasing member and the liquid passage opening is opened by releasing the lid locking mechanism from fixing the lid body. Thus, the container body can be tilted to the opposite side of the hinge portion, and the beverage in the container body can be drunk or injected through the liquid passage port.

The lid locking mechanism described in the following cited document 1 includes an operation button on the upper portion of the lid body, and after an operation of sliding the operation button in a direction toward the hinge portion is performed, the operation button is operated in a direction of being pushed down, whereby the locked state of the lid body is released, and the lid body can be rotated in the opening direction by the biasing force of the biasing member. This prevents the cover from being opened by an inadvertent operation, and further improves the usability.

Further, the lid lock mechanism described in the following cited document 1 includes a lock member rotatably attached to the lid body via a hinge portion. The locking member is rotatable between a locking position where a hook portion (one locking portion) provided on one end side thereof is locked in a locking recess (the other locking portion) provided on the cover body side, and a lock release position where the locked state of the hook portion and the locking recess is released.

Thus, when the lock member is in the lock position, the hook portion is positioned inside the slit provided in the peripheral wall portion of the lid body, and is locked to the locking recess. On the other hand, when the lock member is at the unlocking position, the hook portion protrudes outward from between the slits, and the locked state in which the hook portion is locked to the locking recess is unlocked.

Therefore, in such a lid unit, since the one locking portion projects outward from the slit only when the lid body is unlocked, the one locking portion is located inside the slit in the state where the lid body is locked, and a force in the direction of unlocking the locked state is not easily applied to the lock member.

Patent document 1: japanese patent laid-open publication No. 2017-001741

However, in the lid unit described in the above cited document 1, in order to correspond to a container main body having a relatively large size (capacity), it is required to increase the rotation range of the lock member. That is, in the lid locking mechanism provided in such a lid unit, if the lock member can be rotated largely between the lock position and the unlock position with respect to the operation amount (stroke) of the operation button, it is possible to apply the lid locking mechanism to a beverage container (lidded container) having a larger size (capacity).

The grip portion 12a protrudes from the outer peripheral portion of the shoulder member 12 on the rear side and extends downward.

The cap body 8 is detachably attached to the shoulder member 12 (container body 2) by screwing. Therefore, the internal thread portion 8d is provided on the inner peripheral surface of the peripheral wall portion 8 a.

On the other hand, an external thread portion 12b screwed with the internal thread portion 8d is provided on the outer peripheral surface of the shoulder member 12.

The cap body 8 is not limited to the above-described structure that is detachably attached to the shoulder member 12, and may be a structure that is detachably attached to the mouth-and-neck portion 2c of the container body 2 without the shoulder member 12. In this case, the mouth-and-neck portion 2c may have an outer peripheral surface provided with an external thread portion screwed with the internal thread portion 8 d.

A spout-forming member 13 forming a drinking spout or a pouring spout (drinking spout in the present embodiment) is detachably attached to the opening portion 8b of the cap main body 8. The port forming member 13 is made of a heat-resistant resin such as polypropylene. The mouth forming member 13 has: a bottom wall portion 13a having a liquid passage port 14 and a vent port 15; a cylindrical peripheral wall portion 13b rising upward from the periphery of the bottom wall portion 13 a; a lower flange portion 13c annularly protruding from a lower end side of the outer peripheral surface of the bottom wall portion 13 a; a pair of upper flange portions 13d projecting in opposite directions (left-right direction) from each other from the upper end side of the outer peripheral surface of the peripheral wall portion 13 b; and a drinking spout portion 13e obliquely protruding from the upper end of the peripheral wall portion 13 b.

Wherein the drinking spout portion 13e is located on the front side of the spout-forming member 13. The liquid passage port 14 is provided so as to penetrate through the bottom surface of the recess 14a formed in the bottom wall portion 13 a. The vent 15 is provided to penetrate through the bottom wall 13a located higher than the recess 14 a. The liquid passage port 14 is located closer to the drinking spout portion 13e (front side) than the vent port 15, and is opened in a more elliptical shape in the front-rear direction than the vent port 15 formed as a circular hole.

Between the lid main body 8 and the mouth forming member 13, a detachable mechanism 16 for detachably attaching the mouth forming member 13 to the opening 8b of the lid main body 8 is provided. The attachment/detachment mechanism 16 has a first claw portion 17 on the front side of the mouth forming member 13, and a shutter 19 provided with a second claw portion 18 on the rear side of the mouth forming member 13.

The first claw portion 17 is provided so as to protrude forward from the upper end side of the outer peripheral surface of the peripheral wall portion 13 b. The baffle plate 19 is disposed along the outer peripheral surface of the rear side of the mouth forming member 13. The lower end (base end) of the flap 19 is rotatably supported by a hinge mechanism 13f provided in the mouth forming member 13. The second claw portion 18 is provided so as to protrude rearward from the upper end (front end) side of the shutter 19. The tip of the second claw portion 18 forms an inclined surface 18 a.

An elastic member 20 made of, for example, rubber or an elastic body is disposed between the mouth forming member 13 and the baffle plate 19. The elastic member 20 is attached to a surface of the shutter 19 facing the mouth forming member 13. When the front end side of the shutter 19 is rotated forward, the elastic member 20 is compressed (elastically deformed) between the shutter 19 and the mouth forming member 13, thereby biasing the shutter 19 rearward. Further, an operation portion 19a is provided at an upper end (front end) of the shutter 19, and the operation portion 19a has a concave portion or a convex portion for facilitating a rotational operation of the shutter 19 with a finger.

On the other hand, the attachment/detachment mechanism 16 includes a first engaged portion 21 on the front side of the cover body 8 and a second engaged portion 22 on the rear side of the cover body 8. The first engaged portion 21 and the second engaged portion 22 are stepped portions provided at respective front and rear positions along the opening 8b of the upper wall portion 8 c.

In the attachment/detachment mechanism 16 having the above-described configuration, the mouth forming member 13 is fitted into the opening 8b of the cover main body 8 from below in a state where the first claw portion 17 is positioned with respect to the first locked portion 21. At this time, the pair of upper flange portions 13d come into contact with the lower surface of the upper wall portion 8c of the lid main body 8. The first claw portion 17 is locked to the first locked portion 21. Further, after the inclined surface 18a of the second claw 18 abuts on the edge of the opening 8b of the cover main body 8 and the front end side of the shutter 19 is rotated forward as the second claw 18 passes over the edge of the opening 8b, the front end side of the shutter 19 is returned to the original position rearward, and at the same time, the second claw 18 is locked to the second locked portion 22.

Thereby, the mouth forming member 13 is attached to the opening 8b of the lid main body 8. Simultaneously with the mounting port forming member 13, the drinking port portion 13e protrudes outward (upward) from the opening 8b of the lid body 8.

On the other hand, in the attachment/detachment mechanism 16, the engagement state of the second claw portion 18 with respect to the second portion-to-be-locked 22 is released by an operation of rotating the front end side of the shutter 19 forward. This allows the opening forming member 13 to be removed from the lower side of the opening 8b of the cap body 8 while releasing the locked state of the first claw portion 17 with respect to the first locked portion 21.

The cap body 8 to which the mouth-forming member 13 is attached to the mouth-and-neck portion 2c of the container body 2, and thereby the upper opening portion 2d of the container body 2 is closed in a state where the mouth-forming member 13 is fitted into the upper opening portion 2 d.

A water stop packing 23 is detachably attached to the lower flange portion 13c of the mouth forming member 13. The water seal packing 23 is an annular seal member for sealing the gap between the extension portion 7 (container body 2) and the mouth forming member 13 (lid body 8). The water seal packing 23 is formed of an elastic member such as a heat-resistant rubber such as silicone rubber or an elastic body. The water seal packing 23 is fitted into the outer periphery of the lower flange portion 13 c.

When fitted inside the upper opening 2d of the container body 2, the water seal packing 23 is brought into close contact with the extension 7 of the container body 2 over the entire circumference while being elastically deformed. This makes it possible to seal the space between the extension portion 7 and the mouth forming member 13.

The lid 9 is a member for opening and closing the liquid inlet 14 formed in the port forming member 13, and is formed of a heat-resistant resin such as polypropylene, for example. The lid body 9 has a peripheral wall portion 9a formed in a substantially cylindrical shape so as to be continuous with the peripheral wall portion 8a of the lid main body 8; and a top wall portion 9b covering the top surface of the peripheral wall portion 9 a.

The lid 9 is rotatably attached to the lid main body 8 via a first hinge portion 24. The lid 9 is biased in a direction (opening direction) in which the liquid passage port 14 is opened by a biasing member 24a provided in the first hinge portion 24. In the present embodiment, a torsion coil spring is used as the biasing member 24 a. The biasing member 24a is not limited to a spring member such as a torsion coil spring, and an elastic member such as rubber or an elastic body may be used.

A closing member 25 for closing the liquid passage port 14 formed in the port forming member 13 is provided inside the lid body 9. The lid 9 has an approximately cylindrical inner wall portion 9c located inside a peripheral wall portion 9a descending from the periphery of the top wall portion 9b and descending from the substantially central portion of the lower surface side of the top wall portion 9 b. The closing member 25 is fitted to the inside of the inner wall portion 9 c. A housing space for housing the cover lock mechanism 10 described later is provided inside the plug member 25.

The lid body 9 to which the closing member 25 is attached closes the liquid passage port 14 formed by the port forming member 13 in a state where the closing member 25 is fitted into the port forming member 13.

A cap gasket 26 for sealing the liquid passage port 14 is freely attached to the outer peripheral portion of the plug member 25. The cap gasket 26 is a plug-shaped sealing member for sealing the gap between the mouth forming member 13 and the closing member 25. The cover gasket 26 is made of the same material as the water seal gasket 23. The cover gasket 26 is fitted into the closing member 25 so as to cover the closing member 25. The cap gasket 26 is provided with a first substantially dome-shaped plug portion 26a that abuts the liquid passage port 14, and a second substantially cylindrical plug portion 26b that abuts the air vent port 15.

When fitted inside the port forming member 13, the cap gasket 26 elastically deforms to close the liquid passage port 14 in a state where the first plug portion 26a is in close contact with the periphery of the liquid passage port 14, and to close the air vent 15 in a state where the second plug portion 26b is in close contact with the periphery of the air vent 15. This makes it possible to seal the space between the mouth forming member 13 and the plug member 25.

The lid lock mechanism 10 fixes the lid body 9 at a position where the lid body 9 closes the liquid passage port 14 against the urging force of the urging member 24a provided in the first hinge portion 24. The lid lock mechanism 10 has an operation button 27 on the upper portion of the lid body 9, and after the operation button 27 is slid toward the first hinge portion 24, the operation button 27 is operated in a direction to be pushed down, thereby releasing the locked state of the lid body 9, and the lid body 9 can be rotated in the opening direction by the urging force of the urging member 24 a.

Specifically, the cover lock mechanism 10 has a guide groove 28 for guiding the operation button 27 in a direction to slide it; and a guide hole 29 for guiding the operation button 27 in a direction in which it is pressed.

The operation button 27 is formed in an approximately disc shape, and has a guide convex portion 27a and a restricting convex portion (one restricting member) 27b protruding downward from the guide convex portion 27a on a lower surface thereof. An operation portion 27c is provided on the upper surface of the operation button 27, and the operation portion 27c has a concave portion or a convex portion (concave portion in the present embodiment) for facilitating the sliding operation of the operation button 27 with a finger.

The guide groove 28 is formed by cutting out a substantially central portion of the upper surface side of the lid body 9 (top wall portion 9b) in the front-rear direction by a width corresponding to the operation button 27. The guide hole 29 is located inside the guide groove 28 and penetrates the top wall portion 9b in accordance with the outer shape of the operation button 27.

The lid lock mechanism 10 includes an operation member 30 disposed inside the guide hole 29, and a lock member 32 rotatably attached to the lid 9 via a second hinge portion 31.

The operation member 30 is formed in a substantially disc shape in fit with the inside of the guide hole 29, and is restricted from moving upward relative to the guide hole 29 by a flange portion (not shown) protruding from the outer peripheral portion thereof coming into contact with the periphery of the guide hole 29. The operation member 30 is supported to be vertically movable by engaging a guide rib (not shown) provided on the inner side of the inner wall portion 9c with a guide slit (not shown) provided in the flange portion.

Further, a guide pin 30a is provided to protrude from the lower surface of the operation member 30. On the other hand, a guide tube 25a is provided on the inner bottom surface of the closing member 25 in a protruding manner. Further, the operation member 30 is supported to be vertically movable by engaging the guide pin 30a inside the guide cylinder 25 a.

A third coil spring (third spring member) 33 is disposed inside the closing member 25. The third coil spring 33 is held in a state of being erected from the bottom surface of the plug member 25 by the guide tube 25a being inserted inside. The third coil spring 33 is compressed (elastically deformed) between the operation member 30 and the closing member 25 when the operation member 30 is pressed, thereby urging the operation member 30 in a direction of pushing the same. Further, by providing the third coil spring 33, the locked state of the lid body 9 by the lid lock mechanism 10 can be reliably maintained.

The operation member 30 is provided with a guide recess 30 b. The guide recess 30b is formed by cutting the operation member 30 from the front end toward the rear end of the operation member 30 by a length corresponding to the sliding amount of the operation button 27. The operation member 30 guides (supports) the operation button 27 to be slidable in the front-rear direction in a state where the guide convex portion 27a is engaged with the guide concave portion 30 b.

Further, a first coil spring (first spring member) 34 is disposed inside the guide recess 30 b. The first coil spring 34 is held between the guide convex portion 27a and the guide concave portion 30b in a state where the pin 27d protruding from the rear side surface of the restriction convex portion 27b is inserted into the inside.

When the operation button 27 is slid from one end side (front side) to the other end side (rear side) in the sliding direction (front-rear direction), the first coil spring 34 is compressed (elastically deformed) between the operation button 27 (guide convex portion 27a) and the operation member 30 (guide concave portion 30b), thereby urging the operation button 27 toward the one end side (front side) in the sliding direction (front-rear direction).

Here, one end (front end) of the operation button 27 in the sliding direction (front-rear direction) is at a position (hereinafter, referred to as a first position) where a part of the operation button 27 overlaps the upper surface of the lid 9 (top wall portion 9 b). In the first position, a part of the operation button 27 abuts on the upper surface of the lid body 9 (top wall portion 9b), thereby restricting the pressing operation of the operation button 27.

Further, a regulating pin 25b (another regulating member) opposed to the regulating projection 27b when the operation button 27 is at the first position is provided on the inner bottom surface of the closing member 25. In the first position, the restricting projection 27 is located above the restricting pin 25 b. In this case, even if the operation button 27 is excessively depressed due to deformation of the component or the like, the restricting convex portion 27b abuts against the restricting pin 25b to restrict the pressing operation of the operation button 27, and smooth sliding operation of the operation button 27 can be performed.

On the other hand, the other end (rear end) of the operation button 27 in the sliding direction (front-rear direction) is at a position where the operation button 27 overlaps the guide hole 29 (hereinafter, referred to as a second position). In the second position, the restriction of the restricting convex portion 27b by the restricting pin 25b is released by the restricting convex portion 27b being displaced rearward with respect to the position of the restricting pin 25 b. Thereby, in the second position, the operation button 27 can be pressed.

The second hinge portion 31 is provided inside a corner portion between the peripheral wall portion 9a and the top wall portion 9b on the opposite side (front side) from the first hinge portion 24. Second hinge portion 31 includes a hinge bearing portion 31a provided in lock member 32, and a hinge shaft 31b attached to penetrate hinge bearing portion 31a in the direction of the rotation axis.

The lock member 32 is rotatably supported by the second hinge portion 31. The locking member 32 includes a first arm portion 32a extending from the hinge bearing portion 31a in a direction along the peripheral wall portion 9a, and a second arm portion 32b extending from the hinge bearing portion 31a in a direction along the top wall portion 9 b.

A slit 9d for making the first arm portion 32a face outward is provided on the front side of the lid body 9 (the peripheral wall portion 9 a). The slit 9d is formed by being cut from the lower end side to the upper end side of the peripheral wall portion 9a with a width and length corresponding to the first arm portion 32 a. On the other hand, the outer surface of the first arm portion 32a facing outward from the slit 9d forms an outer peripheral surface continuous with the peripheral wall portion 9a of the lid body 9.

A hook portion (one locking portion) 35 is provided at the tip of the first arm portion 32a (one end of the lock member 32). The front end of the hook 35 protrudes rearward, and the lower surface side of the protruding portion is inclined.

The cover main body 8 is provided with a locking recess (another locking portion) 36 to which the hook portion 35 is locked. The locking recess 36 is formed by cutting the front side of the upper wall portion 8c in accordance with the shape of the hook portion 35.

The lock member 32 rotates between a lock position where the hook portion 35 is locked to the locking recess 36 and an unlock position where the locked state of the hook portion 35 and the locking recess 36 is unlocked.

A second coil spring (second spring member) 37 is provided inside the closing member 25. The second coil spring 37 is held in a state of being erected from the bottom surface of the closing member 25 by inserting the pin 25c protruding from the bottom surface of the inside of the closing member 25 and the pin 32c protruding downward from the tip of the second arm portion 32b (the other end of the lock member 32) into the inside. The second coil spring 37 biases the lock member 32 toward the lock position in the rotational direction in a state compressed between the distal end of the second arm portion 32b and the latch member 25.

In the cover lock mechanism 10 having the above-described configuration, after the operation button 27 is slid from the first position to the second position against the biasing force of the first coil spring 34, the operation button 27 is pushed down toward the inside of the guide hole 29 together with the operation member 30 against the biasing forces of the second coil spring 37 and the third coil spring 33.

Thereby, the operating member 30 presses the tip end of the second arm portion 32b (the other end of the lock member 32), and the lock member 32 is rotated to the lock release position against the urging force of the second coil spring 37. By the operation of the operation button 27 as described above, the locked state of the lid body 9 is released, and the lid body 9 is rotated in the opening direction by the biasing force of the biasing member.

Therefore, in the lid unit 3 provided with the lid locking mechanism 10 of the present embodiment, after the operation of sliding the operation button 27 is performed, the operation of pressing the operation button 27 (operation of so-called 2-action) is performed, whereby the locked state of the lid body 9 is released. Therefore, it is possible to prevent the locked state of the lid body from being released by an inadvertent pressing operation (so-called 1-action operation) of the conventional operation button.

In addition, in the cover unit 3 of the present embodiment, since it is not necessary to provide a conventional safety shutter or the like, it is possible to prevent the cover 9 from being opened by an inadvertent operation without increasing the number of components.

In addition, in the cover unit 3 of the present embodiment, the operation of sliding the operation button 27 and the operation of pressing the operation button 27 can be performed by continuous operations. This eliminates the need to operate the operation button after the cup is removed or to operate the operation button 27 after the safety shutter is released, which can further improve the usability.

As described above, in the lidded container 1 including the lid unit 3 according to this embodiment, it is possible to prevent the lid 9 from being opened by an inadvertent operation, and to further improve the usability.

However, in the lid lock mechanism 10 of the present embodiment, as shown in fig. 6 to 8, a recess 38 corresponding to the hinge bearing portion 31a is provided inside the corner portion between the peripheral wall portion 9a and the ceiling wall portion 9 b.

Thus, in the lid lock mechanism 10 of the present embodiment, in a state where the second hinge portion 31 is disposed inside the lid body 9, the second hinge portion 31 (hinge bearing portion 31a) can be positioned inside the corner portion between the peripheral wall portion 9a and the top wall portion 9 b.

In addition, in the lid lock mechanism 10 of the present embodiment, the second hinge portion 31 includes: a pair of bearing recesses 31c provided inside the corner between the peripheral wall portion 9a and the ceiling wall portion 9b, and a pair of bearing contact portions 31d provided on the closing member 25. Second hinge portion 31 rotatably supports support lock member 32 in a state where both end portions of hinge shaft 31b are fitted into the pair of bearing recesses 31c and the pair of bearing contact portions 31d are in contact with both end portions of hinge shaft 31 b.

Thus, in the lid lock mechanism 10 of the present embodiment, the lock member 32 can be rotatably supported in a state in which the second hinge portion 31 is positioned inside the corner portion between the peripheral wall portion 9a and the top wall portion 9 b.

In the lid lock mechanism 10 of the present embodiment, both ends of the hinge shaft 31b located inside the corner between the peripheral wall portion 9a and the ceiling wall portion 9b can be covered (hidden) by the pair of bearing contact portions 31d (a part of the closing pin member 25).

In the lid unit 3 including the lid lock mechanism 10 of the present embodiment, the second hinge portion 31 is positioned inside the corner portion between the peripheral wall portion 9a and the top wall portion 9b, so that the entire length of the first arm portion 32a of the lock member 32 extending from the hinge bearing portion 31a can be increased. Thus, when the lock member 32 is rotated to the lock release position by the pressing operation of the operation button 27, the rotation range of the first arm portion 32a can be increased.

Therefore, in the lid unit 3 of the present embodiment, the lock member 32 can be rotated largely between the lock position and the unlock position with respect to the operation amount (stroke) in the direction in which the operation button 27 is pushed down, and therefore, the present invention can be applied to a beverage container (lidded container) having a larger size (capacity).

In the cover unit 3 of the present embodiment, since the lock member 32 is configured to protrude outward (forward) from between the slits 9d only when the locked state of the cover 9 is released, the lock member 32 is located inward of the slits 9d in the state where the cover 9 is locked, and a force in the direction of releasing the locked state is not easily applied to the lock member 32. Further, the lock member 32 is not easily broken.

As described above, in the lidded container 1 including the lid unit 3 according to this embodiment, the pivoting range of the lock member 32 can be increased, and the usability can be further improved.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, the container 1 with a lid is not limited to the member having the above-described external shape, and can be appropriately changed in accordance with the size, function, external design, and the like.

The present invention is preferably applied to a lidded container 1 having a heat-retaining/cold-retaining function by the container body 2 having the vacuum heat-insulating structure described above, but is not necessarily limited to a member using the container body 2 having the vacuum heat-insulating structure described above. That is, the present invention can be widely applied to a cap-equipped container in which a cap unit is detachably attached to a mouth-and-neck portion of a container body.
