Detailed Description
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Fig. 1 to 4 are views for explaining one embodiment of the beverage container of the present invention. Fig. 1 and 2 are a side view and a plan view showing the entire configuration of the beverage container, respectively. Fig. 3 is an exploded perspective view showing the beverage container of fig. 1, and fig. 4 is a partial sectional view taken along line I-I of the beverage container of fig. 2. In fig. 3, the straw described later is not shown for clarity.
The beverage container 1 shown in fig. 1 to 4 is a container for a user (mainly an infant) to drink a beverage such as tea or fruit juice through a drinking spout. The beverage container 1 includes a container body 2 and a spout adaptor 3 that forms the spout and is detachably attached to the container body 2. A cap 6 that covers the mouthpiece in a closed state is attached to the mouthpiece adaptor 3. The cap assembly is formed by the mouthpiece adaptor 3 and the cap 6.
The container body 2 is used to contain a beverage therein. As shown in fig. 3, the container body 2 is formed in a cylindrical shape with one end (upper end) open and the other end (lower end) closed. A male screw 2s for attaching the spout adaptor 3 is formed on the outer periphery of the upper end of the container body 2.
The spout adaptor 3 includes an adaptor body 4 attached to the container body 2 and an elastic member 5 held by the adaptor body 4. As will be described later, the elastic member 5 includes a mouthpiece portion 20 for putting the mouth of the user of the beverage container 1.
As shown in fig. 3, one end (upper end) of the adapter main body 4 is formed in a cylindrical shape which is partially closed. Specifically, the adapter body 4 has a cylindrical peripheral wall portion 4a and a top wall portion 4b connected over the entire length of the upper edge of the peripheral wall portion 4 a. As shown in fig. 1 and 4, a female screw 4s is formed on the inner periphery of the lower end of the peripheral wall 4 a. The internal thread 4s is engaged with the external thread 2s of the container body 2. The adapter body 4 can be attached to the container body 2 by engaging the female screw 4s with the male screw 2 s. As shown in fig. 3, a mounting hole 4h for mounting the elastic member 5 is formed in the top wall portion 4 b. The top wall portion 4b is provided with a protruding portion 4c that protrudes from the top wall portion 4b to the side opposite to the container body 2. As shown in fig. 1 and 4, an engaging concave portion 4d that engages with an engaging convex portion 6d of a lid 6 described later and holds the lid 6 in a closed state is formed on a side portion of the protruding portion 4 c.
As shown in fig. 1, 3 and 4, the elastic member 5 includes a plate-like portion 10, a spout portion 20 forming a spout, and a straw storage portion 30 to which a straw 7 is connected. The plate-like portion 10, the spout portion 20, and the straw storage portion 30 are integrally formed. The elastic member 5 is made of a soft material such as silicon in order to adapt the infant to the drink opening portion 20.
As shown in fig. 3, the plate-like portion 10 is flat as a whole. As shown in fig. 4, the plate-like portion 10 is disposed between the top wall portion 4b of the adapter body 4 and the annular upper end surface 2a that defines the opening of the container body 2. The plate-like portion 10 spreads along the top wall portion 4b of the adapter body 4, and forms a seal between the top wall portion 4b and the upper end face 2a of the container body 2. More specifically, the plate-like portion 10 includes a 1 st surface 11 that contacts the adapter body 4 to form a seal portion, and a 2 nd surface 12 that is provided opposite the 1 st surface 11 and contacts the upper end surface 2a of the container body 2 to form a seal portion. As can be understood from fig. 2 and 4, the plate-like portion 10 is provided with a spout opening 14 and a vent hole 15 that communicate with the container body 2 at positions within the mounting hole 4h that becomes the top wall portion 4b, as viewed in the direction (vertical direction) from the top wall portion 4b of the adapter body 4 toward the plate-like portion 10. The vent hole 15 is provided with a valve sheet portion 16 that closes the vent hole 15.
As shown in fig. 3, the spout portion 20 extends from the 1 st surface 11 of the plate portion 10. The spout portion 20 is cylindrical as a whole. As shown in fig. 4, the internal space of the spout portion 20 communicates with the internal space of the container body 2 through the spout opening 14 of the plate portion 10. The spout portion 20 penetrates the mounting hole 4h of the adaptor body 4.
As shown in fig. 2 and 3, a mounting portion 40 for mounting the elastic member 5 to the adaptor body 4 is formed around the spout portion 20 and the vent hole 15. As shown in fig. 4, the mounting portion 40 protrudes from the 1 st surface 11 of the plate-like portion 10 and penetrates the mounting hole 4h of the adapter body 4. An extension protrusion 41 extending outward of the mounting hole 4h is formed at the upper end portion of the mounting portion 40 when viewed in a direction (vertical direction) from the top wall portion 4b of the adapter body 4 toward the plate-like portion 10. The elastic member 5 is held by the adapter body 4 by disposing the extended protruding portion 41 on the opposite side of the top wall portion 4b of the adapter body 4 to the side of the plate-shaped portion 10, in other words, by disposing the edge portion that defines the mounting hole 4h of the top wall portion 4b between the plate-shaped portion 10 and the extended protruding portion 41.
As shown in fig. 1 and 4, the straw storage portion 30 protrudes from the 2 nd surface 12 of the plate-shaped portion 10 into the container body 2. The straw storage portion 30 is cylindrical and is erected around the drinking spout opening 14 of the plate-like portion 10. One end of the straw 7 is connected to the straw storage part 30.
As described above, by integrally forming the respective portions 10, 20, and 30 having different functions, the number of parts of the beverage container 1 can be reduced, and the operability during cleaning can be improved. In addition, the respective parts 10, 20, 30 can be easily assembled to the adapter body 4.
Next, the cover 6 will be explained. As shown in fig. 1 to 3, the lid 6 has a dome shape and covers the spout portion 20 in a closed state. By covering the spout portion 20 with the cover 6, the spout portion 20 can be kept sanitary. The cover 6 is rockably connected to the adaptor body 4 of the drink adaptor 3 about the swing axis Ax. The lid 6 is opened and closed by a relative movement with respect to the mouthpiece adapter 3.
The lid 6 has an inner surface 6a facing the spout 20 in a closed state. An engaging convex portion 6d that engages with the engaging concave portion 4d of the adapter body 4 in a state where the lid 6 is closed is provided on the inner side surface 6 a. The lid 6 is maintained in a closed state by engaging the engaging convex portion 6d with the engaging concave portion 4 d.
The lid 6 has a closing projection 6b projecting from the inner surface 6a thereof, and the spout portion 20 is bent and pressed to be closed in a state where the lid 6 is closed. By closing the spout portion 20, the beverage is prevented from leaking out of the spout portion 20.
The cover 6 has an opening protrusion 6c, and the opening protrusion 6c protrudes from the inner surface 6a of the cover 6, is inserted into the vent hole 15 of the elastic member 5 in a state where the cover 6 is closed, and opens the valve sheet portion 16 covering the vent hole 15. By opening the valve piece 16 of the vent hole 15, the internal pressure of the container body 2 is prevented from rising and the beverage is prevented from leaking from the spout 20.
However, in a beverage container having a container body and a spout adaptor detachably attached to the container body, in order to prevent a beverage from leaking out from between the spout adaptor and the container body when the spout adaptor is attached to the container body, the spout adaptor and the container body need to be brought into close contact with each other to form a seal therebetween. This requires a great deal of force, which impairs the operability of the beverage container. In addition, even if the spout adaptor and the container body are firmly pressed against each other, individual differences occur due to manufacturing errors and the like in the spout adaptor, and it is difficult to stably form a seal between the spout adaptor and the container body.
In view of this, beverage container 1 of the present embodiment is studied to form a sufficiently stable seal without depending on individual differences of spout adaptor 3 (i.e., even if there are individual differences of spout adaptor 3), and to reduce the force required to attach spout adaptor 3 to container body 2, thereby improving the operability of beverage container 1.
Specifically, as shown in fig. 3, the plate-like portion 10 has an annular convex portion 8 on the 1 st surface 11 along the peripheral edge thereof. The annular projection 8 is pressed against the adapter body 4 (more specifically, the top wall portion 4b) in a state where the adapter body 4 is attached to the container body 2.
In the beverage container 1 using the elastic member 5 having the annular convex portion 8 formed on the 1 st surface 11 of the plate-like portion 10, the force for attaching the spout adapter 3 to the container body 2 can be reduced as compared with a beverage container using an elastic member not provided with the annular convex portion 8. This is because, when the spout adapter 3 is attached to the container body 2, the plate-like portion 10 of the elastic member 5 is compressed between the top wall portion 4b of the adapter body 4 and the upper end surface 2a of the container body 2 to form a seal between the elastic member 5 and the upper end surface 2a of the container body 2, but in the case where the annular convex portion 8 is formed on the 1 st surface 11 of the plate-like portion 10, the volume of the elastic member 5 compressed between the top wall portion 4b of the adapter body 4 and the upper end surface 2a of the container body 2 can be reduced as compared with the case where the annular convex portion 8 is not provided.
Further, by forming the annular projecting portion 8 on the 1 st surface 11 of the plate-shaped portion 10, when the spout adaptor 3 is attached to the container body 2, the annular projecting portion 8 of the elastic member 5 is positively brought into close contact with the top wall portion 4b of the adaptor body 4 (that is, the annular projecting portion 8 is brought into close contact with the top wall portion 4b earlier than the other portions of the plate-shaped portion 10), whereby it is possible to reduce the difference in the close contact property between the adaptor body 4 and the elastic member 5 due to the individual difference therebetween. Therefore, a seal can be formed between the adapter body 4 and the elastic member 5 sufficiently stably without depending on individual differences of the mouthpiece adapter 3 (without being affected by individual differences of the mouthpiece adapter 3).
In the illustrated example, as can be understood from fig. 4, the annular projection 8 is disposed along a corner portion of the connection portion 4e between the peripheral wall portion 4a and the top wall portion 4b of the adapter body 4. This stabilizes the arrangement of the annular projection 8, and thus forms a stable seal.
In the illustrated example, as can be understood from fig. 4, at least a part of the annular projection 8 is located on the annular upper end surface 2a of the container body 2. Further, the width 8w of the annular projecting portion 8 is smaller than the width 2w of the upper end surface 2a of the adapter body 2 as viewed in a direction (vertical direction) from the top wall portion 4b of the adapter body 4 toward the plate-like portion 10. Thus, when the spout adapter 3 is attached to the container body 2, the volume of the elastic member 5 compressed between the top wall portion 4b of the adapter body 4 and the upper end surface 2a of the container body 2 can be effectively reduced as compared with the case where the annular projecting portion 8 is not provided. Further, when the spout adaptor 3 is attached to the container body 2, the annular convex portion 8 can be effectively brought into close contact with the top wall portion 4b of the adaptor body 4 positively (that is, the annular convex portion 8 can be brought into close contact with the top wall portion 4b earlier than the other portions of the plate-shaped portion 10).
In the illustrated example, the annular convex portion 8 is formed integrally with the plate-like portion 10 and protrudes from the 1 st surface 11 of the plate-like portion 10. By supporting the annular projecting portion 8 by the plate-like portion 10 in this way, twisting and the like of the annular projecting portion 8 can be prevented, and the arrangement of the annular projecting portion 8 can be stabilized. Therefore, a stable seal can be formed between the annular protrusion 8 and the adapter body.
The annular upper end surface 2a of the container body 2 has an annular 1 st upper end surface 2b facing the top wall portion 4b of the adapter body 4 and an annular 2 nd upper end surface 2c which is continuous from the outside or the inside of the annular 1 st upper end surface 2b and is inclined with respect to the top wall portion 4 b. When the spout adaptor 3 is attached to the container body 2, the annular 1 st upper end surface 2b of the upper end surface 2a of the container body 2 comes into contact with the plate-like portion 10 of the elastic member 5 earlier than the annular 2 nd upper end surface 2c, and the plate-like portion 10 is compressed to form a seal between the adaptor body 4 and the elastic member 5. This also reduces the force for attaching the spout adaptor 3 to the container body 2. This is because the volume of the elastic member 5 compressed between the top wall portion 4b of the adapter body 4 and the upper end surface 2a of the container body 2 can be reduced as compared with the case where the entire annular upper end surface 2a of the container body 2 faces the top wall portion 4 b.
In the illustrated example, the 2 nd upper end surface 2c is connected to the 1 st upper end surface 2b from the outside thereof, and is inclined toward the outside of the annular upper end surface 2a toward the lower side in the vertical direction of the container body 2 with respect to an opening surface (a surface surrounded by the annular end surface) defined by the container body 2. This allows the annular protrusion 8 to be pressed toward the corner portion serving as the connecting portion 4e between the top wall portion 4b and the peripheral wall portion 4 a. This also stabilizes the arrangement of the annular projection 8, and enables a stable seal to be formed between the annular projection 8 and the adapter body 4.
As shown in fig. 4, the annular projection 8 is located outside the 1 st upper end face 2b (i.e., outside the upper edge 2d of the 2 nd upper end face 2 c). This enables the annular protrusion 8 to be pressed more effectively toward the corner portion serving as the connecting portion 4e between the top wall portion 4b and the peripheral wall portion 4 a. Therefore, the arrangement of the annular projection 8 can be effectively stabilized, and a more stable seal can be formed between the annular projection 8 and the adapter body 4.
According to the above-described one embodiment, the beverage container 1 includes the cylindrical container body 2 having one end open and the other end closed, and the spout adaptor 3 attached to at least partially close the opening and forming the spout. The spout adaptor 3 includes an adaptor body 4 attached to the container body 2 and an elastic member 5 held by the adaptor body 4. The elastic member 5 includes a 1 st surface 11 that forms a seal portion by being in contact with the adapter body 4 and a 2 nd surface 12 that is provided opposite to the 1 st surface 11 and forms a seal portion by being in contact with an end surface of the container body 2. The 1 st surface 11 is provided with an annular projection 8 that is pressed against the adapter body 4 in a state where the adapter body 4 is attached to the container body 2.
According to such a beverage container 1, the volume of the elastic member 5 that is crushed when the spout adaptor 3 is attached to the container body 2 can be reduced, and the force for attaching the spout adaptor 3 to the container body 2 can be reduced. Further, since the annular convex portion 8 of the elastic member 5 is positively brought into close contact with the adapter body 4 when the mouthpiece adapter 3 is attached to the container body 2, it is possible to reduce the possibility of a difference in the close contact property between the adapter body 4 and the elastic member 5 due to individual differences therebetween. Therefore, a seal can be formed between the adapter body 4 and the elastic member 5 sufficiently stably without depending on individual differences of the mouthpiece adapter 3. As described above, according to the beverage container 1, the seal can be formed sufficiently stably without depending on individual differences of the spout adapter 3, and the force required for attaching the spout adapter 3 to the container body 2 can be reduced, whereby the operability of the beverage container 1 can be improved.
In the above specific example, the adapter body 4 has a cylindrical peripheral wall portion 4a and a top wall portion 4b connected over the entire length of the peripheral wall portion 4 a. The annular projection 8 is disposed along the connecting portion 4e between the top wall 4b and the peripheral wall 4 a. Thus, the annular projection 8 is arranged along the corner portion of the connecting portion 4e between the top wall portion 4b and the peripheral wall portion 4a, and the arrangement of the annular projection 8 can be stabilized. As a result, a stable seal can be formed between the annular projection 8 and the adapter body 4.
In the above-described specific example, the end face 2a of the container body 2 has an inclined face (2 nd upper end face) 2c inclined downward toward the outside with respect to the opening face defined by the container body 2. This allows the annular projecting portion 8 to be pressed toward the corner portion of the connecting portion 4e between the top wall portion 4b and the peripheral wall portion 4a, and effectively stabilizes the arrangement of the annular projecting portion 8. As a result, a stable seal can be effectively formed between the annular projection 8 and the adapter body 4.
In the above-described specific example, the annular projection 8 is located outside the upper edge 2d of the inclined surface (2 nd upper end surface) 2 c. This effectively realizes the stable arrangement of the annular protrusion 8 by pressing the annular protrusion 8 toward the corner portion of the connecting portion 4e between the top wall portion 4b and the peripheral wall portion 4 a. Further, a stable seal can be effectively formed between the annular convex portion 8 and the adapter body 4.
In the above specific example, the adapter body 4 has a cylindrical peripheral wall portion 4a and a top wall portion 4b connected over the entire length of the peripheral wall portion 4 a. The elastic member 5 includes a plate-like portion 10 extending along the top wall portion 4b, and the annular convex portion 8 is formed integrally with the plate-like portion 10 and protrudes from the plate-like portion 10. Since the annular projecting portion 8 is supported by the plate-like portion 10, twisting of the annular projecting portion 8 and the like can be prevented, and the arrangement of the annular projecting portion 8 can be stabilized. This enables a stable seal to be formed between the annular protrusion 8 and the adapter body 4.
In the above-described specific example, the hole (mounting hole) 4h is formed in the top wall portion 4b of the adapter body 4. The elastic member 5 has a spout portion 20 formed integrally with the plate portion 10 to form a spout. The spout portion 20 is inserted through a hole 4h provided in the top wall portion 4b of the adapter body 4. By integrally forming the respective portions 10 and 20 having different functions in this manner, the number of parts of the beverage container 1 can be reduced, and the workability during cleaning and the like can be improved. In addition, the respective parts 10 and 20 can be easily assembled to the adapter body 4.
In the above-described specific example, the beverage container 1 further includes an openable and closable lid 6 that covers the spout in a closed state. By covering the spout portion 20 with the cover 6, the spout portion 20 can be kept sanitary.
Alternatively, according to the above-described embodiment, the cap assembly is a cap assembly attached to the container body 2, and includes the spout adaptor 3, and the spout adaptor 3 is attached so as to at least partially close the opening of the container body 2 and has a spout formed therein. The spout adaptor 3 includes an adaptor body 4 attached to the container body 2 and an elastic member 5 held by the adaptor body 4. The elastic member 5 includes a 1 st surface 11 which is in contact with the adapter body 4 to form a seal portion, and a 2 nd surface 12 which is provided opposite to the 1 st surface 11 and is in contact with the end surface 2a of the container body 2 to form a seal portion, and the 1 st surface 11 is provided with an annular projection 8 which is pressed against the adapter body 4 in a state where the adapter body 4 is attached to the container body 2.
According to such a cap assembly, the volume of the elastic member 5 that is crushed when the spout adaptor 3 is attached to the container body 2 can be reduced, and the force for attaching the spout adaptor 3 to the container body 2 can be reduced. Further, since the annular projection 8 of the elastic member 5 can be positively brought into close contact with the adapter body 4 when the spout adapter 3 is attached to the container body 2, it is possible to reduce the possibility of a difference in the close contact property between the adapter body 4 and the elastic member 5 due to individual differences therebetween. Therefore, a seal can be formed between the adapter body 4 and the elastic member 5 sufficiently stably without depending on individual differences of the mouthpiece adapter 3. As described above, according to the cap assembly, it is possible to form a seal sufficiently stably without depending on individual differences of the spout adaptor 3, and to reduce the force required for attaching the spout adaptor 3 to the container body 2, thereby improving the operability of the beverage container 1.
One embodiment is described with reference to a plurality of specific examples, but these specific examples are not intended to limit the one embodiment. The above-described embodiment can be implemented in various other specific examples, and various omissions, substitutions, and changes can be made without departing from the spirit thereof. For example, the shape of the spout 20 is not limited to the illustrated shape, and various shapes can be adopted. The annular projection 8 may be separate from the plate-like portion 10.
