Beverage container

The present invention relates to a beverage container in which a beverage can be contained.

Conventionally, for example, in a beverage container such as a cup used for drinking beverages such as infants and young children, there is a case where a lid is placed on the container, and a straw is placed on the lid. The beverage container with a straw has the advantage that the infant or the like can practice using the straw to drink the beverage in the container, and is used by many parents such as mothers.

The beverage container with a straw is placed in a state in which a beverage is contained therein, and in a state in which a straw is placed, in order to allow a parent or the like to carry it around, a cover is provided so that the straw is closed and the straw is covered.

However, if the heated milk or the like is contained in the beverage container with the straw attached thereto, and the outer cover is closed and carried by the parent, the pressure inside the container becomes high, and a pressure difference from atmospheric pressure is generated. Therefore, when the parent opens the cover at the destination of the movement or the like, and the occlusion state of the straw is released, there is a problem that the beverage such as heated milk in the container is ejected from the straw.

Therefore, according to the conventional technique, a vent hole or the like that communicates with the space inside the container is provided on the lid of the beverage container to prevent the beverage such as milk in the container from being ejected from the straw or the like in advance.

On the other hand, when the vent hole is present, there is a problem that the beverage in the container leaks when the parent or the like carries the beverage container with the straw in the handbag or the like.

Therefore, there is proposed a structure in which the vent hole is a valve structure or a vent hole is ventilated when the outer cover is opened. In addition, a structure in which a vent hole is closed when a beverage container having a straw is carried or a drink containing a straw drinking beverage container such as an infant is proposed (for example, Patent Document 1).

Therefore, as shown in FIG. 2, when the outer cover 5 is opened, the hinge projection 7c is engaged with the hinge recess 7d, as shown in FIG. 2, which is configured to fix the angle of the outer cover 5 and the middle cover 3 at 250 degrees. about.

As shown in FIG. 3, the middle cover 3 is formed with two upper positioning portions 3a and 3b formed on the upper concave portion 3k from the upper surface thereof via the step portion. The two outer cover positioning protrusions 3a, 3b are used to guide to the correct closing position when the outer cover 5 is moved to the blocking position toward the middle cover 3, and abut the outer peripheral end of the outer cover 5 Parts 5c and 5d (see Fig. 4).

Therefore, as shown in FIG. 1, when the outer cover 5 is placed on the inner cover 3, the outer cover 5 can be positioned with high precision. This is a case where only the hinge member 7 of FIG. 2 is used, and the outer cover 5 cannot be accurately positioned.

Further, as shown in FIG. 3, a hinge receiving portion 3c is also formed in the middle cover 3 for mounting the above-described hinge member 7.

Further, as shown in FIG. 2, the suction pipe 8 is attached to the middle cover 3 so as to protrude obliquely.

Therefore, even when the user's infant or the like opens the outer cover 5 as shown in FIG. 2, and holds the handles 4a, 4b, including the straw 8, and drinks the beverage in the container body 2, since the outer cover 5 can be opened to 250 Since the position is fixed and the outer cover 5 is not in contact with the user's face or the like, the structure can be easily consumed.

As shown in FIG. 3 and FIG. 4, in the central recessed portion 3k of the middle cover 3, a suction pipe insertion hole 3d for inserting the suction pipe 8 as described above, and a vent valve mounting hole 3e for attaching the venting valve 10 which is a venting portion to be described later are formed. .

As shown in FIGS. 3 and 4, the suction pipe 8 and the vent valve 10 are connected to each other to form one piece. In this way, in addition to reducing the number of parts and reducing the manufacturing cost, the chance of parts being lost can be reduced. In addition, the straw 8 is formed of a soft resin member or the like which is soft even if it is contained in a mouth by a user such as an infant.

Further, as shown in Fig. 4, on both sides of the straw insertion perforation 3d on the inner side of the inner lid 3, suction pipe positioning projections 3f and 3g which are projections for positioning the suction pipe 8 are formed. These straw positioning projections 3f and 3g have different sizes (shapes) as shown in Fig. 4 .

On the other hand, on the side of the suction pipe 8, as shown in Fig. 3, the pipe positioning recessed portions 8a and 8b are formed to correspond to the size (shape) of the suction pipe positioning bosses 3f and 3g, respectively.

Therefore, when the user or the like inserts the straw 8 into the straw insertion hole 3d of the middle cover 3, the suction pipe positioning recesses 8a, 8b are attached so as to fit the straw positioning projections 3f, 3g, so that the suction pipe 8 is placed. The direction of the configuration does not constitute an error.

Further, when the straw 8 is attached to the middle cover 3 in this manner, the suction pipe 8 is disposed such that the side of the lips or the like of the user or the like is disposed obliquely upward toward the left side of FIG. 2, and the vent valve 10 is disposed in FIG. On the right side, that is, from the side of the user's lips or the like from the straw 8.

Therefore, when the user or the like tilts the sippy cup 1 and drinks the beverage from the suction pipe 8, the vent valve 10 is at a position higher than the suction pipe 8, and the structure prevents leakage of the beverage from the vent valve 10.

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

The slit 10a, as shown in Fig. 5, is provided in a dome-shaped top portion that protrudes to the side of the container body 2 in the vent valve 10. Therefore, when the user sucks the beverage through the suction pipe 8, when the inside of the container body 2 becomes a negative pressure, the dome-shaped top portion moves to the container body 2 side and is deformed to have a structure in which the slit 10a is easily opened.

That is, it is a structure that easily sucks air into the container body 2. Therefore, it is possible to prevent the user from having difficulty in attracting the beverage via the suction pipe 8 due to the negative pressure in the container body 2 in advance.

In the present embodiment, the slit 10a has been described as an example of the opening. However, the opening of the present invention includes not only the slit 10a but also a vent hole or the like.

However, as shown in FIG. 3 and FIG. 5, the drinking port closing portion is protruded from the table portion 31 of the middle cover 3, that is, for example, the first middle cover side closing projection 3h is disposed to protrude from the predetermined interval. And the second middle cover side closing projection 3i.

On the other hand, as shown in FIG. 4 and FIG. 5, the outer cover side closing protrusion 5e which is a drinking port clogging part is protruded.

As shown in FIG. 4, when the center cover 3 is closed, the outer cover side closing projection 5e is arranged to enter the first middle cover side closing projection 3h and the second middle cover side closing. Use between the protrusions 3i.

In addition, as shown in FIG. 5, the suction pipe 8 is bent in a W shape by the outer cover side closing projection 5e, the first middle cover side closing projection 3h, and the second middle cover side closing projection 3i. The internal space of the straw 8 is partially blocked.

In other words, the suction pipe 8 is crushed at three positions in the longitudinal direction of the suction pipe 8, and the suction pipe 8 having the closed structure can be reliably closed, so that the leakage of the beverage can be surely prevented.

However, the sippy cup 1 of the present embodiment has the leakage preventing plate 12 disposed so as to be movable to the outer cover 5 as described above, and therefore will be described in detail below.

As shown in FIGS. 3 and 4, the leakage preventing plate 12 has a cover side plate 12j formed of a flat plate-like member on the side of the middle cover 3, and the leakage preventing plate 12 is made outward by the flat surface of the cover side plate 12j. When the cover 5 is moved, it becomes a structure in which the center cover 3 can smoothly move.

Further, as described above, the leakage preventing plate 12 is disposed to be movable inside the outer cover 5, and specifically has the following structure.

As shown in Fig. 3, the leakage preventing plate 12 has two plate side guiding claws 12a provided at fixed intervals on both sides along its moving direction (the direction of the arrow X1 in Fig. 4). The plate-side guide claws 12a are configured to be engaged with the outer cover side claws 5f in the outer cover 5 of Fig. 4, and are movable in the direction of the arrow X1 in Fig. 4 . That is, the leakage preventing plate 12 is configured to be slidable to the outer cover 5.

Further, as shown in FIG. 3, the leakage preventing plate 12 has two projections 12b for preventing falling off. That is, the leakage preventing plate 12 of FIG. 3 is attached to the outer cover 5, and can be moved in the direction of the arrow X1 of FIG. 4 and the like, for example, when the cover side guiding claw 5f of FIG. 4 is located in FIG. When the two plate-side guide claws 12a are in the longitudinal direction, there is a possibility that the leakage preventing plate 12 is detached from the outer cover 5.

Therefore, the leakage preventing plate 12 is formed on the outer cover 5 as shown in FIG. 4, while the two anti-dropping projections 12b are provided, and the stopper 5g against which the anti-dropping projection 12b abuts.

Therefore, the leakage preventing plate 12 which is engaged with the outer cover 5 and movable in the direction of the arrow X1 of FIG. 4 is configured such that the two anti-dropping projections 12b shown in FIG. 3 are abutted in FIG. The stopper 5g restricts its movement and can be prevented from coming off the outer cover 5 in advance.

Further, when the leakage preventing plate 12 is detached from the outer cover 5, it is configured such that the user or the like moves the leakage preventing plate 12 until the detachment preventing projection 12b crosses the stopper 5g.

In this way, the leakage preventing plate 12 has a structure in which the leakage preventing plate 12 can be easily removed by being detached from the outer cover 5, and thus the user can easily maintain the sippy cup 1 in a sanitary state.

In addition, the detached leakage preventing plate 12 is configured such that the plate-side guiding claws 12a and the outer cover 5 are engaged with the guiding claws 5f, so that the outer cover 5 can be easily attached. In this manner, the leakage preventing plate 12 has a structure in which the outer cover 5 can be easily attached and detached.

However, as shown in FIG. 4, two engaging claws 12g are formed to protrude from the flat middle side panel 12j formed on the cover 3 side of the leakage preventing plate 12 in the direction of the arrow X1. The engaging claw 12g is attached to the cover 5 of the outer cover of FIG. 4 in the leakage preventing plate 12, and the outer cover 5 is arranged such that the centering cover 3 is closed as shown in FIG. It is engaged with the engaged member 3j of the cover 3 shown in FIG. 3, and the outer cover 5 is engaged with the middle cover 3.

As shown in FIG. 3, the engaged member 3j is formed so as to protrude from the land portion 31 of the middle cover 3 toward the leakage preventing plate 12 side, and is formed between the engaging member 3j and the table portion 31 to prevent leakage. The engaging claw 12g of the plate 12 is inserted into the hole portion.

Therefore, when the outer lid 5 is engaged and fixed to the inner lid 3, as shown in Fig. 5, the straw 8 is covered by the first middle lid side closing projection 3h, the second middle lid side closing projection 3i, and the outer lid side closing projection. The 5e is closed, and the structure in which the beverage in the container body 2 leaks from the straw 8 can be surely prevented.

Further, as shown in FIG. 3 and FIG. 4, the leakage preventing plate 12 is formed with a releasing operation portion, for example, a releasing piece 12c so as to protrude in the direction of the arrow X1 in FIG.

The release piece 12c is configured such that when the cover 5 is placed on the inner cover 3 with the leakage preventing plate 12 attached thereto, the user or the like presses the outer cover or the like to press the claw of the leakage preventing plate 12 12g is detached from the engaged member 3j of Fig. 3, and the engagement of the outer cover 5 and the middle cover 3 is released.

Therefore, the user can easily release the engagement between the outer cover 5 and the middle cover 3 by operating the release piece 12c.

In the leakage preventing plate 12 of Fig. 3, a spring mounting region 12d in which the spring member 13 of Fig. 3 is disposed is formed. Further, a spring mounting cutout portion 12e for fixing the spring neck portion 13a of Fig. 3 is formed in the leakage preventing plate 12.

Thus, when the spring member 13 attached to the leakage preventing plate 12 is disposed in the outer cover 5 of FIG. 3 together with the leakage preventing plate 12, the spring rear end portion 13b of the spring member 13 of FIG. 3 abuts outside FIG. The spring abutment portion 5i of the cover 5.

Therefore, in this state, the leakage preventing plate 12 is configured to be energized in the X1a direction of the arrow X1 in Fig. 4 by the spring member 13, and the releasing piece 12c integrally formed with the leakage preventing plate 12 is also The X1a direction of the arrow X1 of Fig. 4 is energized.

When the leakage preventing plate 12 is engaged with the outer cover 5, the releasing piece 12c is disposed in the releasing piece opening 5h (see FIG. 4) formed in the outer cover 5, and is disposed in a direction in which the outer cover 5 protrudes. Empowerment. Therefore, as shown in FIG. 5, the release piece 12c is arranged so that the user or the like can easily operate.

In other words, the user can resist the ability of the spring member 13 to press the release piece 12c, thereby moving the leakage preventing plate 12, and the engagement between the outer cover 5 and the middle cover 3 can be released.

On the other hand, when the user or the like does not operate the release piece 12c, the outer cover 5 is engaged with the inner cover 3 by the ability of the spring member 13.

Further, as shown in FIG. 4 and FIG. 5 and the like, the releasing piece holding claw 12f is formed in the releasing piece 12c so as to protrude in the moving direction.

In response to the release sheet holding claws 12f, as shown in Fig. 5, the cover side closing projections 5e are provided on the outer cover 5 to form a release piece holding claw opening 5j for inserting and holding the release piece holding claws 12f.

Therefore, the moving direction of the sheet 12c is released, and the releasing sheet holding claw 12f is slid in the releasing sheet holding claw opening 5j, whereby the hanging piece 12c can be prevented from hanging down in advance.

However, as shown in FIG. 4, the cover side plate 12j is formed in the leakage preventing plate 12, and the occlusion ventilation part 12h is formed.

As shown in Fig. 7, the occlusion venting portion 12h has the protruding portion 12ha protruding from the cover side plate 12j to the middle cover 3 side from the leakage preventing plate 12, and is released from one side of the protruding portion 12ha. On the side of the piece 12c, the ventilation securing portion 12hb has a gentle slope (inclination) from the apex portion of the protruding portion 12ha.

When the leakage preventing plate 12 is attached to the outer lid 5 and the outer lid 5 and the middle lid 3 are engaged with each other, the occlusion venting portion 12h is a closed structure that covers the occluding vent valve 10 as shown in Fig. 5 .

Specifically, the protruding portion 12ha shown in FIG. 7 has a shape that is the same as or slightly larger than the upper surface of the cylindrical portion 10b (refer to FIG. 3) of the vent valve 10, and as shown in FIG. 5, when the outer cover 5 is closed In the state (one example of the closed position), the vent valve 10 is surely covered and closed.

Since the vent valve 10 has the slit 10a as shown in FIG. 4, the beverage in the container main body 2 does not easily leak out. However, in the present embodiment, the ventilating valve 10 is further covered with the protruding portion 12ha of the occlusion/ventilating portion 12h. The cylindrical portion 10b of the valve 10 is for surely preventing leakage of the beverage.

In particular, when the peripheral resin is deteriorated due to a long-term change in the slit 10a, the vent valve 10 is closed by the protruding portion 12ha. Therefore, when the outer lid 5 is closed, the container body 2 can be reliably prevented. The leak of the drink.

As shown in FIG. 3, the vent valve 10 has a cylindrical tubular portion 10b, and a plate-like portion 10c formed by the slit 10a is disposed inside the ventilating valve 10b.

As shown in FIG. 5, the plate-like portion 10c has a substantially dome shape formed so as to protrude to the container body 2 side, and a slit 10a is formed at the top portion thereof.

Further, the protruding portion 12ha of the occlusion/conviving portion 12h is disposed such that the cylindrical portion 10b and the slit 10a are opposed to each other.

Further, in the present embodiment, as shown in Fig. 5, the slit 10a is provided on the top of the dome-shaped plate-like portion 10c which protrudes to the container body 2 side. Therefore, when the user sucks the beverage through the suction pipe 8, and the inside of the container body 2 becomes a negative pressure, the dome-shaped top portion is elastically deformed toward the container body 2 side, and the slit 10a is configured to be easily opened.

That is, it is a structure which can easily inhale air into the container main body 2. Therefore, the situation in which the user draws the beverage via the suction pipe 8 can be prevented in advance by the negative pressure in the container body 2.

Further, as shown in FIG. 3 and the like, the slit 10a is an elongated slit, and its longitudinal direction intersects with the direction of the arrow X1 of the moving direction of the leakage preventing plate 12 of FIG. 4, and is disposed, for example, in the present embodiment.

Therefore, as shown in FIG. 5, when the user or the like operates the release piece 12c while the outer cover 5 and the middle cover 3 are engaged, the release piece 12c is moved in the X1b direction in the direction of the arrow X1 in FIG. Then the occlusion and ventilation part 12h will also face Move in the same direction (one example of the ventilation position).

Specifically, as shown in FIG. 8, by moving the protruding portion 12ha of the occlusion/ventilating portion 12h horizontally, the upper surface of the tubular portion 10b of the vent valve 10 that abuts is moved. At this time, the shape of the vent valve 10 is deformed, and as shown in Fig. 6, the slit 10a is opened.

In this way, since the crack in the longitudinal direction of the slit 10a is arranged to be orthogonal to the direction of the arrow X1, the projection 12a that closes the ventilating portion 12h can easily expand the operation of the slit 10a.

That is, as shown in Fig. 6, the slit 10a is greatly enlarged by the use of the protruding portion 12ha.

In the present embodiment, as shown in FIG. 8, when the occlusion/ventilation unit 12h is moved in the X1b direction of FIG. 5 by the movement of the unclamping piece 12c, the ventilating securing portion 12hb and the tubular portion that close the venting portion 12h are configured. Between the portions 10b, a venting path 14 is secured to ensure that the venting from the slit 10a is discharged to the outside.

As described above, in the present embodiment, before the user opens the outer cover 5 by the release piece 12c and the occlusion of the suction pipe 8 is released, the slit 10a is forcibly opened by the protruding portion 12ha, and the ventilation is ensured by the ventilation path 14, and the container body is secured. The pressure inside 2 is also released, so that it is possible to prevent the beverage such as warm milk in the container body 2 from being ejected from the straw 8 in advance.

Further, in the present embodiment, the release sheet 12c and the occlusion/ventilation portion 12h are integrally formed in the leakage preventing plate 12. Therefore, the action of releasing the piece 12c is caused The cooperation with the occlusion/ventilation portion 12h is confirmed. For example, it is possible to prevent the occurrence of a problem that the vent valve 10 is not ventilated even if the release piece 12c is operated to close the protruding portion 12ha of the ventilating portion 12h.

As described above, in the present embodiment, the ventilation securing portion 12hb abuts against the tubular portion 10b of the vent valve 10, and when the vent valve 10 is closed, the leakage preventing plate 12 is moved by the operation of the releasing piece 12c. Since the structure of the air passage 14 can be ensured, the damper state and the ventilating state of the vent valve 10 can be made reliable.

Further, in the present embodiment, the gap 10a is provided in the vent valve 10, so that the beverage in the container main body 2 can be prevented from leaking, and the pressure release in the container main body 2 can be easily performed.

Further, by the occlusion ventilation portion 12h, it is possible to completely prevent the beverage from leaking from the slit 10a in advance. In addition, in order to prevent the beverage from being ejected from the straw 8 when the outer lid 5 is opened, the projection 12a of the venting portion 12h is closed, and the slit 10a is forcibly expanded. Therefore, it becomes a sippy cup 1 which a user can use easily.
