Description

Beverage container

The present invention relates to a beverage container that can contain a beverage therein.

2. Description of the Related Art Conventionally, for example, some beverage containers such as cups used when infants drink beverages have a lid disposed on the container and a straw disposed on the lid. Such a beverage container with a straw has an advantage that an infant or the like can practice drinking the beverage in the container using a straw, and is used by many parents such as mothers.
The beverage container with a straw is formed with an outer lid placed so as to cover the straw with the straw closed so that a guardian etc. can carry it with the beverage inside and the straw placed in it. Has been.

However, when warmed milk or the like is accommodated in the beverage container with a straw and the outer lid is closed and carried by a guardian, the pressure in the container increases and a differential pressure from the atmospheric pressure is generated. For this reason, when the guardian opens the outer lid at the destination and releases the closed state of the straw, there is a problem that warm milk or the like in the container is ejected from the straw.
For this reason, conventionally, the lid of the beverage container is provided with a vent hole or the like communicating with the space in the container to prevent the beverage such as milk in the container from being ejected from a straw or the like. .

On the other hand, when such a vent hole is present, there is a problem that a beverage in the container leaks when a guardian or the like accommodates the beverage container with a straw in a bag or the like and carries it.
For this reason, a structure in which the vent hole has a valve structure and a structure in which the vent hole is ventilated when the outer lid is opened have been proposed. In addition, when carrying a beverage container with a straw, or when an infant or the like holds a straw and drinks a beverage in a beverage container, a proposal has been made that the vent hole is closed (for example, Patent Document 1).

Japanese Patent Laid-Open No. 2006-335464 (FIGS. 5, 7 and 8, etc.)

However, even if a configuration in which a vent is used to close the vent hole as in the invention of Patent Document 1, the convex portion is provided on the sliding member, and the position of the convex portion is shifted and the passage is made. In some cases, the pores cannot be closed with high accuracy. In this case, there is still a problem that the beverage in the beverage container leaks out. Further, even if the vent hole has a valve structure, there is a problem that a beverage leaks out even when a malfunction or the like occurs in the valve itself.

Then, this invention aims at providing the drink container which can maintain the release | release of the pressure in a drink container effectively and for a long period of time, and can prevent the leak of the drink in a drink container etc. effectively. To do.

According to the present invention, the object is to provide a container main body for containing a beverage, an inner lid portion that covers the container main body, a drinking mouth portion that is formed in the inner lid portion and that discharges the beverage, and the drinking A mouthpiece closing portion that closes the mouth portion, an outer lid portion that is detachably disposed with respect to the inner lid portion, a ventilation portion that secures ventilation to the outside of the container body, the outer lid portion, and the A release operation portion for releasing the engagement with the inner lid portion, and when the outer lid portion is disposed so as to be closed with respect to the inner lid portion, the ventilation portion is closed. And an obstructing and ventilating portion that is disposed at the venting position where the venting portion is vented based on the releasing operation of the releasing operation portion. At least a part of the dual-purpose part secures a ventilation path from the ventilation part to the outside. It is achieved by a beverage container, characterized in that a vent securing unit.

According to the said structure, when arrange | positioning so that an outer cover part may be in a closed state with respect to an inner cover part, while being arrange | positioned in the obstruction | occlusion position which can make a ventilation part obstruct | occluded, cancellation | release of a cancellation | release operation part Based on the operation, it includes a closed ventilation portion that is disposed at a ventilation position where the ventilation portion is in a ventilation state. For this reason, when the outer lid portion is arranged so as to be closed with respect to the inner lid portion, that is, when the user or the like is moving the container, for example, in a bag or the like, the ventilation portion is Since it is obstruct | occluded by the obstruction | occlusion ventilation combined use part, the leakage of the drink in a container main body can be prevented beforehand.
On the other hand, if the ventilation part is closed by the closed ventilation part, the leakage of the beverage can be suppressed, but the pressure in the container body is not sufficiently released, and there is a possibility that the beverage may be ejected from the drinking mouth part.
Therefore, in the above-described configuration, the block ventilation portion is also arranged at the ventilation position where the ventilation portion is in a ventilation state based on the release operation of the release operation portion.
Further, at the ventilation position, at least a part of the closed ventilation combined part functions as a ventilation securing part that secures a ventilation path from the ventilation part to the outside.
For this reason, for example, when the user or the like operates the release operation part to release the engagement between the outer lid part and the inner lid part, the ventilation part is brought into a ventilation state by the closed ventilation part and the closure is performed. Since at least a part of the ventilation / use part functions as the ventilation securing part, the pressure release in the container body is prevented from being insufficiently released.

Preferably, the ventilation portion has a slit portion formed of an elastic member, and the blocking ventilation portion is moved in accordance with the operation of the release operation portion so that the slit portion is moved. It is characterized by a configuration that can be expanded.

According to the said structure, the block ventilation part can expand a slit part by moving the position corresponding to operation | movement of the cancellation | release operation part.
For this reason, when the engagement of the outer lid portion and the inner lid portion is released by the operation of the release operation portion, the slit portion is surely widened to ensure the release of pressure in the container body, It is possible to prevent eruption from the drinking mouth. Further, it is not necessary to perform a separate operation for releasing the pressure in the container body, and a complicated operation is not necessary.

Preferably, the ventilation portion has a tubular portion, the slit portion is provided in the tubular portion, and the closed ventilation portion is in contact with the tubular portion. And

According to the above configuration, the slit portion is provided in the tubular portion of the ventilation portion, and the closed ventilation portion is brought into contact with the tubular portion. For this reason, since the cylindrical part which contact | abuts the obstruction | occlusion ventilation combined use part will move together, a slit part can be expanded reliably.

On the other hand, as shown in FIG. 3, straw positioning recesses 8a and 8b are formed on the straw 8 side, and have sizes (shapes) corresponding to the

straw positioning bosses

3f and 3g, respectively.
For this reason, when a user or the like inserts the straw 8 into the straw insertion hole 3d of the inner lid 3, the straw positioning recesses 8a and 8b are attached so as to fit the

straw positioning bosses

3f and 3g. The configuration is such that the orientation of the arrangement of 8 is not mistaken.

In addition, when the straw 8 is mounted on the inner lid 3 in this way, the straw 8 is disposed facing diagonally upward to the left in FIG. 2 on the side where the lips of the user or the like are disposed. It is arranged on the right side of FIG. 2, that is, on the side away from the user's lips and the like from the straw 8.
For this reason, when a user etc. inclines the straw cup 1 and drinks a drink from the straw 8, the vent valve 10 becomes a position higher than the straw 8, and it can prevent that a drink leaks out from the vent valve 10. It has become.

The vent valve 10 is formed of an elastic body, and, as shown in FIGS. 3 and 4, a slit 10 a, which is a slit portion for releasing the pressure in the container body 2, is formed at a substantially central portion thereof. .

Therefore, in this Embodiment, it becomes the structure by which the drink inside the container main body 2 cannot leak easily by the slit 10a.
As shown in FIG. 5, the slit 10 a is provided at the top of the vent valve 10 that protrudes toward the container body 2. For this reason, when a user sucks a beverage through the straw 8 and the inside of the container main body 2 becomes negative pressure, the dome-shaped top moves to the container main body 2 side, deforms, and the slit 10a is easily opened. It has a configuration.
That is, the air is easily sucked into the container body 2. Therefore, it is configured to prevent the user from sucking the beverage through the straw 8 due to the negative pressure in the container body 2.
In the present embodiment, the slit 10a is described as an example of the opening, but the opening of the present invention includes not only the slit 10a but also a vent hole and the like.

By the way, as shown in FIG.3 and FIG.5, on the base part 3l of the inner lid 3, for example, the 1st inner lid side obstruction | occlusion protrusion 3h which is a drinking mouth obstruction | occlusion part, and 2nd inner lid side obstruction | occlusion The protrusions 3i are disposed so as to protrude through a predetermined interval.
On the other hand, on the outer lid 5 side, as shown in FIGS. 4 and 5, an outer lid-side closing projection 5 e that is a drinking mouth closing portion protrudes.

As shown in FIG. 4, when the outer lid 5 is closed with respect to the inner lid 3, the outer lid-side closing projection 5 e is connected to the first inner lid-side closing projection 3 h. 2 is arranged so as to enter between the middle lid side closing projections 3i.
At this time, as shown in FIG. 5, the straw 8 is formed in a W shape by the outer lid side closing projection 5e, the first inner lid side closing projection 3h, and the second inner lid side closing projection 3i. The inner space of the straw 8 is partially closed.
That is, in the longitudinal direction of the straw 8, the straw 8 can be reliably closed by crushing and closing the straw 8 at three locations, and the beverage can be more reliably prevented from leaking. It has become.

By the way, since the straw cup 1 of this Embodiment is provided with the leak prevention plate 12 arrange | positioned so that a movement with respect to the outer cover 5 is mentioned above, it is explained in full detail below.
As shown in FIGS. 3 and 4, the leakage prevention plate 12 has an inner lid side plate 12j made of a flat plate-like member on the inner lid 3 side. By the flat surface of the inner lid side plate 12j, When the leakage prevention plate 12 moves with respect to the outer lid 5, the leakage prevention plate 12 can move smoothly with respect to the inner lid 3.
Further, as described above, the leakage prevention plate 12 is movably disposed inside the outer lid 5 and specifically has the following configuration.

As shown in FIG. 3, the leakage prevention plate 12 has plate-side guide claws 12 a that are each provided with a predetermined interval on each side along the moving direction (the direction of arrow X <b> 1 in FIG. 4). . The plate-side guide claw 12a engages with the outer lid-side claw 5f arranged corresponding to the outer lid 5 in FIG. 4 and is configured to be movable in the direction of the arrow X1 in FIG. That is, the leakage prevention plate 12 is slidably disposed with respect to the outer lid 5.

As shown in FIG. 3, the leakage prevention plate 12 has two bosses 12b for retaining. 3 is mounted on the outer lid 5 and is movable in the direction of the arrow X1 in FIG. 4 or the like, for example, two plate-side guide claws arranged in the longitudinal direction in FIG. If the outer lid side guide claw 5f of FIG. 4 is positioned between 12a, the leakage prevention plate 12 may be detached from the outer lid 5.
For this reason, the leakage prevention plate 12 is provided with two retaining bosses 12b, and a stopper 5g with which the retaining boss 12b abuts is formed on the outer lid 5 as shown in FIG.

Therefore, the leakage prevention plate 12 that engages with the outer lid 5 and is movable in the direction of the arrow X1 in FIG. 4 has the two retaining bosses 12b shown in FIG. 3 abutting against the two stoppers 5g in FIG. Therefore, the movement is restricted, and it can be prevented from coming off from the outer lid 5 in advance.
When removing the leakage prevention plate 12 from the outer lid 5, the user or the like moves the leakage prevention plate 12 until the retaining boss 12b gets over the stopper 5g.
Thus, since the leak prevention plate 12 can be removed from the outer lid 5 and the leak prevention plate 12 is easily cleaned, the user or the like maintains the straw cup 1 in a sanitary state. The configuration is easy to make.
Conversely, the removed leakage prevention plate 12 can be easily attached to the outer lid 5 by engaging the plate-side guide claw 12a with the outer lid guide claw 5f of the outer lid 5. It is also. As described above, the leak prevention plate 12 is configured to be easily detachable from the outer lid 5.

By the way, as shown in FIG. 4, two engaging claws 12g are formed so as to protrude from the flat inner lid side plate 12j formed on the inner lid 3 side of the leakage prevention plate 12 along the arrow X1 direction. ing. When the leakage prevention plate 12 is attached to the outer lid 5 of FIG. 4 and the outer lid 5 is disposed so as to be closed with respect to the inner lid 3 as shown in FIG. The outer lid 5 is engaged with and fixed to the inner lid 3 by engaging with the engaged member 3j of the inner lid 3 shown in FIG.
As shown in FIG. 3, the engaged member 3j is formed so as to protrude from the base portion 3l of the inner lid 3 toward the leakage prevention plate 12, and between the engaged member 3j and the base portion 3l. Is formed with a hole into which the engagement claw 12g of the leakage prevention plate 12 can be inserted.
Therefore, when the outer lid 5 is engaged and fixed with respect to the inner lid 3, as shown in FIG. 5, the straw 8 has a first inner lid side closing projection 3h and a second inner lid side closing projection. 3d and the outer lid side closing projection 5e are configured to reliably prevent the beverage in the container body 2 from leaking out of the straw 8.

Further, as shown in FIGS. 3 and 4, for example, a release piece 12 c that is a release operation portion is formed on the leak prevention plate 12 so as to protrude along the direction of the arrow X <b> 1 in FIG. 4.
The release piece 12c is configured such that when the outer lid 5 on which the leak prevention plate 12 is mounted is disposed on the inner lid 3, the user or the like performs an operation such as pushing in from the outside, so that the engagement pawl of the leak prevention plate 12 is engaged. 12g is configured to be disengaged from the engaged member 3j in FIG. 3 and the engagement between the outer lid 5 and the inner lid 3 is released.
Therefore, the user can easily release the engagement between the outer lid 5 and the inner lid 3 only by operating the engagement piece 12c.

3 is provided with a spring mounting region 12d in which the spring member 13 of FIG. 3 is disposed. Further, the leakage preventing plate 12 is formed with a spring mounting notch 12e for fixing the spring neck 13a of FIG.
As described above, when the spring member 13 mounted on the leakage prevention plate 12 is disposed on the outer lid 5 of FIG. 3 together with the leakage prevention plate 12, the spring rear end portion 13b of the spring member 13 of FIG. 4 abuts against the spring abutting portion 5 i of the outer lid 5.
Therefore, in this state, the leakage prevention plate 12 is urged by the spring member 13 in the X1a direction of the arrow X1 in FIG. 4, and the release piece 12c formed integrally with the leakage prevention plate 12 is similarly illustrated. 4 is configured to be biased in the X1a direction of the arrow X1.

The release piece 12 c is disposed in the release piece opening 5 h (see FIG. 4) formed in the outer lid 5 when the leakage prevention plate 12 is engaged with and attached to the outer lid 5. It is urged and arranged in the protruding direction. For this reason, the release piece 12c is arranged so as to be easily operated by a user or the like, as shown in FIG.
That is, the user can release the engagement between the outer lid 5 and the inner lid 3 by moving the leakage prevention plate 12 by pushing the release piece 12 c against the urging force of the spring member 13. It has a configuration.
On the other hand, when the user or the like does not operate the release piece 12 c, the outer lid 5 is engaged with the inner lid 3 by the biasing force of the spring member 13.

As shown in FIGS. 4 and 5, the release piece 12 c is formed with a release piece holding claw 12 f so as to protrude along the moving direction.
Corresponding to the release piece holding claw 12f, as shown in FIG. 5, the release piece holding claw opening 5j for inserting and holding the release piece holding claw 12f is inserted into the outer lid side closing projection 5e of the outer lid 5. Is formed.

Therefore, the movement direction of the release piece 12c can prevent the release piece 12c from hanging down by the release piece holding claw 12f sliding in the release piece holding claw opening 5j.

By the way, as shown in FIG. 4, the middle lid side plate 12j of the leakage prevention plate 12 is formed with a closed ventilation portion 12h.
As shown in FIG. 7, the closed ventilation combined portion 12 h has a protruding portion 12 ha protruding from the middle lid side plate 12 j of the leakage prevention plate 12 toward the inner lid 3, and is one side of the protruding portion 12 ha. 4 has a ventilation securing portion 12hb that has a gentle slope (inclination) from the apex portion of the protruding portion 12ha.

As shown in FIG. 5, the closed ventilation / use portion 12 h covers and closes the ventilation valve 10 when the leakage prevention plate 12 is attached to the outer lid 5 and the outer lid 5 is engaged with the inner lid 3. It is the composition to do.
Specifically, the protruding portion 12ha shown in FIG. 7 has the same or slightly larger shape as the upper surface of the tubular portion 10b (see FIG. 3) of the vent valve 10, and as shown in FIG. When in the closed state (an example of a closed position), the vent valve 10 is reliably covered and closed.
Since the vent valve 10 has a slit 10a as shown in FIG. 4, the beverage in the container body 2 is less likely to leak, but in the present embodiment, the protruding portion 12ha of the closed ventilation combined portion 12h is further provided. By covering the cylindrical portion 10b of the vent valve 10, the beverage is surely prevented from leaking out.
In particular, when the surrounding resin deteriorates due to the aging of the slit 10a, the vent valve 10 is closed by the protruding portion 12ha, so that when the outer lid 5 is closed, the beverage in the container body 2 leaks. It can be surely prevented.

As shown in FIG. 3, the vent valve 10 has a cylindrical cylindrical portion 10b, and a plate-shaped portion 10c in which a slit 10a is formed is disposed therein.
As shown in FIG. 5, the plate-like portion 10 c has a substantially dome shape formed so as to protrude toward the container body 2, and a slit 10 a is formed at the top.

Then, the protruding portion 12ha of the closed ventilation portion 12h is disposed so as to face and close to the cylindrical portion 10b and the slit 10a.
Moreover, in this Embodiment, as shown in FIG. 5, the slit 10a is provided in the top part of the dome-shaped plate-shaped part 10c which protruded in the container main body 2 side. For this reason, when a user sucks a beverage through the straw 8 and the inside of the container main body 2 becomes negative pressure, the top of the dome shape is pulled toward the container main body 2 side, elastically deforms, and the slit 10a opens. It has an easy configuration.
That is, the air is easily sucked into the container body 2. Therefore, it is configured to prevent the user from sucking the beverage through the straw 8 due to the negative pressure in the container body 2.

Further, as shown in FIG. 3 and the like, the slit 10a has a long and narrow cut, and its longitudinal direction intersects with the arrow Y1 direction which is the moving direction of the leakage prevention plate 12 in FIG. For example, it arrange | positions so that it may orthogonally cross.
Therefore, as shown in FIG. 5, in a state where the outer lid 5 is engaged with the inner lid 3, the user or the like operates the release piece 12 c, and in the X1b direction of the arrow X1 direction of FIG. 4, When the release piece 12c is moved, the closed ventilation portion 12h is also moved in the same direction (an example of a ventilation position).
Specifically, as shown in FIG. 8, the protruding portion 12ha of the closed ventilation combined portion 12h moves horizontally, so that the upper surface of the tubular portion 10b of the vent valve 10 that is in contact is moved. . At this time, when the shape of the vent valve 10 is deformed, the slit 10a is opened as shown in FIG.

Thus, since the slit in the longitudinal direction of the slit 10a is disposed so as to be orthogonal to the arrow X1 direction, the protruding portion 12ha of the closed ventilation portion 12h can easily operate to widen the slit 10a. ing.
That is, as shown in FIG. 6, the slit 10a is greatly expanded by the protrusion 12ha.

In the present embodiment, as shown in FIG. 8, when the closed ventilation / use portion 12 h moves in the X1b direction of FIG. 5 due to the movement of the release piece 12 c, the air flow securing portion 12 hb of the closed ventilation / use portion 12 h and the cylindrical Between the part 10b, the ventilation path 14 for ensuring that the ventilation | gas_flowing from the slit 10a is discharged | emitted outside is comprised.
Thus, in this embodiment, before the user opens the outer lid 5 with the release piece 12c and releases the blockage of the straw 8, the slit 10a is forcibly opened by the protrusion 12ha, and the ventilation Is ensured by the air passage 14 and the pressure in the container body 2 is also released, so that a beverage such as warm milk in the container body 2 can be prevented from being ejected from the straw 8 in advance.

In the present embodiment, the release plate 12 c and the closed ventilation portion 12 h are integrally formed on the leak prevention plate 12. For this reason, the operation of the release piece 12c and the cooperation of the closed ventilation portion 12h are ensured. For example, the projection 12ha of the closed ventilation portion 12h operates the ventilation valve 10 even though the release piece 12c is operating. It is possible to prevent the occurrence of harmful effects such as preventing ventilation.
As described above, in the present embodiment, the ventilation securing portion 12hc contacts the cylindrical portion 10c of the ventilation valve 10, closes the ventilation valve 10, and the leakage prevention plate 12 moves by operating the release piece 12c. In this case, since the ventilation passage 14 is secured, the closed state and the ventilation state of the ventilation valve 10 can be ensured.

Moreover, in this Embodiment, it becomes the structure which can make it hard to leak the drink in the container main body 2, and can also perform the pressure release in the container main body 2 easily by providing the slit 10a in the ventilation valve 10. FIG. .
And by the obstruction | occlusion ventilation combined use part 12h, the leak of an emergency drink from the slit 10a can be prevented beforehand. Further, in order to prevent the beverage from being ejected from the straw 8 when the outer lid 5 is opened, the slit 10a is forcibly expanded by the protruding portion 12ha of the closed ventilation portion 12h. Therefore, the straw cup 1 is easy for the user to use.
