Means for solving the problems

The beverage container according to the present invention is characterized by comprising a container body, a lid body which is rotatably mounted in the circumferential direction and is detachably attached to an opening of the container body by screwing, and a closing member which is assembled to the lid body to close the gap between the lid body and the opening of the container body, wherein the back surface of the lid body and the surface of the closing member have an engagement convex portion provided on one side and an engagement concave portion provided on the other side, which are engaged with each other in the circumferential direction.

In the present invention, the engagement convex portion may have an annular convex portion along a circumferential direction and a plurality of rib convex portions protruding radially from the annular convex portion, the engagement concave portion may have an annular concave portion along a circumferential direction and a plurality of rib concave portions recessed radially from the annular concave portion, the annular convex portion and the annular concave portion may be fitted to each other, and the rib convex portion and the rib concave portion may be engaged with each other in the circumferential direction.

When the closing member is assembled to the lid body, the annular protruding portions and the annular recessed portions can be fitted to each other to be easily positioned, and when the closing member is screwed to the container body, the lid body and the closing member engage the rib protruding portions and the rib recessed portions with each other in the circumferential direction, so that co-rotation and the like can be easily suppressed.

The engaging portion (engaging concave portion and engaging convex portion) has a ring portion (annular concave portion and annular convex portion) and a rib portion (rib concave portion and rib convex portion) extending in the radial direction, which are arranged along the circumferential direction, so that unexpected deformation which may occur due to, for example, the wall thickness of the closing member can be easily handled, and the area where the lid body and the closing member are brought into close contact with each other can be increased, and therefore, rigidity can be easily ensured.

Preferably, the plurality of ribs are provided at intervals in the circumferential direction, so that the ribs can have engagement portions engaged in the circumferential direction in a dispersed manner, and the engagement force is easily stabilized.

In the present invention, the annular protruding portion may be provided continuously radially inward from an annular groove portion formed in a rear surface peripheral edge portion of the lid body, the annular recessed portion may be provided continuously radially inward from an annular protruding portion formed in a front surface peripheral edge portion of the closing member, and a top portion of the container body may be brought into contact with a rear surface of the closing member below the annular protruding portion fitted in the annular groove portion.

The lid body and the closing member can be further improved in adhesion by fitting the annular groove and the annular projection provided at the peripheral edge portion of each other, in addition to the engagement portion.

In addition, at the time of screwing, the top of the container body presses the annular protrusion of the closing member toward the annular groove of the lid body, so that the fitting force of the protrusion into the groove becomes strong, and the sealing performance is excellent.

In the present invention, it is preferable that the closing member integrally has a suction pipe portion press-fitted into the through hole formed in the lid and located on the front surface side of the lid, and a ventilation portion having a ventilation hole formed therein, and the suction pipe protrusion of the suction pipe portion and the ventilation protrusion of the ventilation portion are engaged with the front surface of the lid.

In this way, the straw projection and the ventilation projection of the closing member are engaged with the front surface side of the lid body, so that the closing member can be prevented from coming off the lid body, and the lid body and the closing member can be assembled with excellent ease.

In the beverage container according to the present invention, a lid member closing an upper portion of the lid body may be provided with a curved portion closing the suction pipe portion, the lid body may be rotatably provided with a rotation operation member engaged with the lid member, the rotation operation member may include an operation arm portion opening and closing the vent hole, the operation arm portion may be biased in a direction closing the vent hole by a biasing member, the operation arm portion may be moved in a direction opening the vent hole by pressing the rotation operation member, and an engaged state of the lid member may be released.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, since the lid and the closing member are engaged with each other in the circumferential direction, when the lid and the closing member are screwed into the container body, the common rotation and the like are suppressed, so that the twisting is easily prevented, and by assembling the closing member to the lid, forgetting to install or poor installation can be prevented.

1 Beverage container, 10 container body, 20 closing member, 30 lid, 40 lid member.

Detailed Description

Hereinafter, a structural example of the beverage container according to the present invention will be described with reference to the drawings.

Fig. 1 is an external perspective view of a beverage container 1, fig. 2 is an exploded view, fig. 3 is a cross-sectional view, and fig. 4 is an enlarged cross-sectional view of the vicinity of a lid body 30 and a closing member 20.

In the beverage container 1, the lid body 30 to which the closing member 20 is assembled is attached to the opening of the container body 10 by screwing and is detachably attached, and the lid member 40 is provided so as to be openable and closable so that the straw portion 23 extending upward of the lid body 30 can be bent and closed.

Hereinafter, each member constituting the beverage container will be described in detail with respect to a direction around the central axis O as a circumferential direction and a direction intersecting the central axis O as a radial direction when viewed from the central axis O of the container body 10, the closing member 20, and the lid body 30.

The container body 10 has a bottomed tubular shape, and has a screw portion 11 on an outer peripheral surface of an opening portion located at an upper portion.

Further, a handle member having a grip for holding an infant may be detachably provided on the outside of the container body 10.

The lid body 30 has a top tubular shape, and has a screwed portion 32a screwed with the screwed portion 11 of the container body on an inner peripheral surface of a peripheral wall portion 32 extending downward from an outer side of a peripheral edge portion of the lid body top wall portion 31.

The lid top wall 31 has a pressing portion hole 31a, a suction portion hole 31b, and a vent portion hole 31c as through holes penetrating the inside and outside of the container so as to be arranged substantially in the front-rear direction.

The pressing portion 22, the straw portion 23, and the ventilation portion 24 of the closing member 20 described later are exposed to the outside of the container through the through holes 31a, 31b, and 31 c.

On the surface of the lid top wall 31, a standing portion 31d is provided between the suction pipe portion hole 31b and the ventilation portion hole 31c, and the suction hole 31e penetrates the inside and outside of the container on both left and right sides of the ventilation portion hole 31 c.

Fig. 5 (a) shows a left side view of the lid top wall 31 from the back side.

The lid top wall 31 has an annular groove 33 formed in a peripheral edge portion (rear surface peripheral edge portion) along a circumferential direction, and an engagement protrusion 34 is provided continuously inward in a radial direction from the annular groove 33.

The present embodiment has an annular convex portion 34a in the circumferential direction and a plurality of substantially rectangular rib convex portions 34b protruding from the annular convex portion 34a toward the radial inner side (central axis O).

The number of rib protrusions is not particularly limited, but is preferably plural with a spacing in the circumferential direction.

For example, by having a plurality of rib protrusions at equal intervals in the circumferential direction, the engagement force is easily made uniform, but the plurality of rib protrusions may have different shapes and sizes.

The closing member 20 is made of an elastic material such as silicone rubber or elastomer.

The closed top wall portion 21 is arranged along the back surface of the lid top wall portion 31, and the back surface of the lid top wall portion 31 is in opposed contact with the surface of the closed top wall portion 21.

The pressing portion 22, the suction pipe portion 23, the ventilation portion 24, and the suction valve 25 formed in the closed top wall portion 21 correspond to the pressing portion hole 31a, the suction pipe portion hole 31b, the ventilation portion hole 31c, and the suction hole 31e of the lid top wall portion 31.

In the present embodiment, the pressing portion 22 has a substantially elliptical shape corresponding to the pressing portion hole 31a, extends upward from the closed top wall portion 21 to have a predetermined thickness, and protrudes upward from the surface of the lid top wall portion 31 through the pressing portion hole 31 a.

The drinking opening 23a of the straw part 23 is pushed into the straw part hole 31b from the back surface side of the lid top wall 31, and the conical straw protrusion 23b is locked to the surface of the lid top wall 31.

The suction pipe protrusion 23b is provided to facilitate sealing with the suction pipe portion hole 31b, and the drinking opening 23a located outside the container can be prevented from coming out to the back surface side of the lid top wall portion 31.

An insertion portion 23c is formed inside the container of the suction pipe portion 23, and one end of the main pipe 23e is detachable from the insertion portion 23c via an auxiliary pipe 23d, so that the disassembly cleaning can be easily performed, and in this embodiment, a weight 23f having a suction port is attached to the other end of the main pipe 23 e.

The vent hole 24a of the vent portion 24 penetrates the container inside and outside, and the conical annular vent protrusion 24b is pressed into the vent portion hole 31c, is positioned on the surface side of the lid top wall 31, and is locked to the upper edge portion of the vent portion hole 31 c.

As a result, like the straw projection 23b, the vent projection 24b easily seals the vent portion hole 31c, and the vent portion 24 can be fixed to the lid top wall 31.

The suction valve 25 has a slit extending in the front-rear direction formed in a hemispherical surface recessed below, for example, and the suction hole 31e of the lid top wall 31 is located above the slit.

A view of the closed top wall portion 21 as seen from the surface is shown on the right side of fig. 5 (a).

An annular projection 26 is provided on the surface of the closed top wall 21 at a peripheral edge portion (surface peripheral edge portion), and an engagement recess 27 is provided continuously radially inward from the annular projection 26 so as to engage with the engagement projection 34 of the lid top wall 31.

The engagement recess 27 of the present embodiment is constituted by an annular recess 27a formed in the circumferential direction and a plurality of substantially rectangular rib recesses 27b recessed radially inward from the annular recess 27 a.

As shown in fig. 5 (b), in the assembled state of the lid body 30 and the closing member 20, the annular convex portion 34a and the rib convex portion 34b of the lid body top wall portion 31 are accommodated in the annular concave portion 27a and the rib concave portion 27b of the closing top wall portion 21, respectively.

When the lid body 30 is rotated in the circumferential direction and screwed into the container body 10 in this state, the rib convex portions 34b of the lid body 30 engage with the rib concave portions 27b of the closing member 20 in the circumferential direction.

For example, as shown in fig. 3 and 4, when the lid body 30 having the closing member 20 assembled thereto is screwed into the opening of the container body 10, the top 12 of the container body 10 abuts against the back surface of the annular projection 26 located in the annular groove 33, and the opening is closed.

When the pressing portion 22 exposed from the lid body 30 is lightly pressed, the interior of the container body 10 is pressurized, and the beverage placed in the container body rises through the interior passage of the straw portion 23 (including the tubes 23d and 23 e).

At this time, if the entire closing member 20 is excessively lowered downward, air leaks from the suction valve 25, and the beverage is less likely to rise in the straw portion, but in this embodiment, the straw protrusion 23b and the ventilation protrusion 24b are engaged with the surface of the lid top wall 31, and therefore, only the vicinity of the pressing portion 22 is lowered, and the beverage rises in the straw portion.

The closing member 20 has the straw portion 23 and the ventilation portion 24 integrally, so that the number of parts is reduced, and the sealing performance between the container body 10 and the lid body 30 is further improved.

As will be described later, the ventilation hole 24a of the ventilation portion 24 is closed by the action arm portion 53 of the rotation action member 51 during drinking, and the container body 10 is in a high airtight state.

If the auxiliary function of raising the beverage in the straw portion by lightly pressing the pressing portion is provided as in the present embodiment, for example, an infant using a nursing bottle can easily practice the operation of sucking the straw, and can smoothly transfer from the nursing bottle to the straw-type beverage container.

In this embodiment, the weight 23f is provided at the other end of the main body tube 23e, so that, for example, the suction port can be easily moved according to the inclination of the beverage container, and the liquid beverage can be easily sucked.

As shown in fig. 2, the cover member 40 is rotatably and openably attached to a pivot 35 provided on the back surface side of the cover top wall 31 by a pivot shaft 36.

The lid member 40 has a curved portion 41 for bending the side portion of the straw portion 23 to close the inside, and a cover front end portion 42 which becomes the front side when closed, and has an engaging portion 43.

The cover body 30 (peripheral wall 32) has a substantially U-shaped mounting portion 37 formed on the front outer side thereof, and the closed state of the cover member 40 can be maintained and opened by the lock member 50, the rotation operating member 51, the urging member 55, and the like mounted in the mounting portion 37.

The slide arm portion 50b of the lock member 50 extends from the substantially elliptical lock body portion 50a to the rear surface side, and is attached to the rotation acting member 51 so as to be slidable in the up-down direction.

The present embodiment is provided with an operation protrusion 50c protruding on the front side of the lock main body portion 50a, for example, the lock main body portion 50a slides to hook the operation protrusion 50c.

The rotation acting member 51 has a locking piece 52 on the rear surface side of the longitudinal base portion 51a, an acting arm portion 53 below the locking piece 52, and a rotation shaft 54 and a biasing member 55 are disposed below the acting arm portion 53.

The locking piece 52 extends from the upper portion of the base 51a toward the rear surface side, and is engaged with the locking portion 43 of the lid member 40, thereby closing the lid member 40.

The action arm portion 53 extends from the base portion 51a to the rear surface side so as to be slightly longer than the locking piece 52 and to be inclined upward, and has an action protrusion 53a protruding downward at the front end portion of the rear surface side, and the action protrusion is fitted into the vent hole 24a.

The rotation shaft 54 is inserted through a shaft hole formed on the rear surface side of the base 51a, and is shaft-fitted into a fitting hole 37a formed in the fitting portion 37 of the cover 30, whereby the rotation acting member 51 can be rotatably fitted to the cover 30.

The biasing member 55 such as a spring member is held by a holding portion 56 provided on the back side of the base 51a and a holding portion 37b formed on the front side in the mounting portion 37 of the cover 30, and is positioned below the rotation shaft 54.

The rotation acting member 51 biases the locking piece 52 to the rear side (rightward in fig. 3 and 6) by the elastic restoring force of the biasing member 55 between the holding portions 56 and 37b, and the acting protrusion 53a is fitted into the ventilation hole 24a to close the acting arm 53 so as to press the ventilation portion 24 from above.

As shown in fig. 6 (a), in a state where the locking portion 42 of the cover member 40 is locked with the locking piece 52 of the rotation acting member 51, the suction pipe portion 23 is sandwiched between the bending portion 41 provided protruding from the cover member 40 and the suction pipe protrusion 23b located at a position corresponding to the bending portion 41, and is bent in a substantially S-shape by abutting against the standing portion 31 d.

Thereby, the straw part 23 is accommodated in the space between the lid member 40 and the lid body 30, and the internal passage of the straw part 23 is broken to prevent the beverage from leaking from the drinking port 23 a.

At this time, the rotation acting member 51 is biased by the biasing member 55 in a direction to fit the acting protrusion 53a into the vent hole 24a, and thus the vent hole 24a is closed in a state where the lid member 40 is closed, and even if the beverage container is tipped over, leakage of the beverage is easily prevented.

In the present embodiment, the locking member 50 and the cover 30 are provided so as to be able to abut in the front-rear direction, whereby the closed state of the cover member 40 can be easily maintained.

As shown in fig. 6 (a), the locking lower portion 50d of the locking member 50 that slides downward relative to the rotation acting member 51 is opposed to the mounting lower portion 37c formed in the mounting portion 37 of the cover 30 in the front-rear direction.

When the locking member 50 is pressed toward the rear surface side in this state, the locking lower portion 50d abuts against the mounting lower portion 37c, and therefore the rotation acting member 51 cannot be rotated.

That is, the cover member 40 maintains a closed state.

Further, by providing the facing surfaces of the lock member 50 and the rotation acting member 51 with restricting portions such as steps that can be passed over in the up-down direction, the free sliding movement can be restricted and the sliding operation can be performed with a small force.

In such a locked state, the lid member 40 is not simply opened even if the lid member is erroneously brought into contact with the locking member 50, for example, when the beverage container is carried.

As shown in fig. 6 (b), by sliding the lock member 50 upward relative to the rotation acting member 51, the facing state of the lock lower portion 50d and the attachment lower portion 37c can be released, and the locked state can be released.

As shown in fig. 6 (c), when the cover member 40 is opened, the rotation acting member 51 is rotated by pressing the locking member 50 to the rear surface side, the locking piece 52 is disengaged from the locking portion 42, and the cover member 40 is opened by the restoring force in the direction of extension of the suction pipe portion 23.

At this time, by the rotation of the rotation operation member 51, the operation protrusion 53a is released from the vent hole 24a, and the internal pressure of the container body can be released from the open vent hole 24a, and the container body 10 can be made to have the same external pressure.

Further, a torsion coil spring may be attached around the pivot shaft 36, and the lid member 40 may be easily rotated in a direction away from the rotation acting member 51 by the urging force of the torsion coil spring, so that the lid member 40 may be easily opened.

When the hand is released from the lock member 50 and the pressing is stopped, the urging force of the urging member 55 returns the urging protrusion 53a to the position where it is fitted into the vent hole 24a, the vent hole 24a is closed again, and the internal passage of the standing straw portion 23 is opened, so that the beverage in the interior does not leak from the drinking port 23a by the internal pressure.

When the beverage is sucked in the state where the lid member 40 is opened, the urging force of the urging member 55 maintains the state where the acting protrusion 53a is fitted into the vent hole 24 a.

When the beverage in the container body 10 is reduced in suction, the suction can be continued simply by opening the slit of the suction valve 25 and introducing the outside air into the container body 10 through the suction hole 31e in order to release the depressurized state in the container body.

Fig. 7 shows another embodiment.

In the present embodiment, the closed top wall portion 21 has, instead of the pressing portion 22, a hole closing portion 28 recessed upward to close the opening of the pressing portion hole 31a, and the surface of the hole closing portion 28 is flush with the surface of the lid top wall portion 31.

Such a beverage container without auxiliary functions is suitable for infants and infants who end up drinking straw drinking exercises, for example.

Further, a valve structure that is opened by deformation and suction of the drinking port may be provided in the drinking port 23a side of the straw portion 23, so that the infant can take the beverage without stuffy, and the beverage can be prevented from leaking and flying out from the drinking port when the lid member is opened or tipped over.
