Detailed Description
Fig. 1 to 9 are views for explaining one embodiment of the beverage container of the present invention. Fig. 1 and 2 are a perspective view and a side view respectively showing the entire structure of the beverage container. The beverage container of the present embodiment is intended mainly for infants and is used for promoting the infants to train drinking of beverages such as tea and fruit juice from a container having a large opening such as a cup, and further for promoting the training of drinking beverages. In addition, studies have been made on the beverage container for preventing the beverage from leaking from the spout when the beverage container is tilted or when the internal pressure of the beverage container rises during carrying of the beverage container. In addition, for example, when a hot beverage is poured into a beverage container or when the internal pressure of the beverage container rises due to taking the beverage container stored in the refrigerator out of the refrigerator, a situation has been studied in which the beverage in the beverage container is prevented from leaking from the spout.
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The beverage container 1 shown in fig. 1 and 2 includes: a container main body 2; and a spout adaptor 3 which forms a 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 mouthpiece adaptor 3 and the cap 6 constitute a cap assembly. Hereinafter, each part of the beverage container 1 will be described in further detail with reference to fig. 1 to 9. Fig. 3 is a perspective view showing the spout adapter 3 and the lid 6 of the beverage container 1 from the side of connecting the container body 2, and fig. 4 is a sectional view along the slit 7 of the spout adapter 3 and the lid 6. FIGS. 5 and 6 are sectional views of the mouthpiece adaptor 3 and the cap 6 taken along the lines I-I and II-II of FIG. 4, respectively. Fig. 7 is a view corresponding to fig. 4, and is a sectional view showing the spout adaptor 3 and the cap 6 in a state where the cap 6 is closed. FIGS. 8 and 9 are sectional views of the spout adaptor and cap, respectively, taken along lines III-III and IV-IV of FIG. 7.
The container body 2 is formed in a cylindrical shape having one end (upper end) opened and the other end (lower end) closed, for containing a beverage therein. 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 10 for sucking by a user of the beverage container 1.
The adapter body 4 is formed in a cylindrical shape with one end (upper end) 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. 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. The top wall portion 4b is formed with a mounting hole 4h to which the elastic member 5 is mounted. 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. An engaging recess 4d that engages with an engaging projection 6d of a lid 6 described later and holds the lid 6 closed is formed on the side of the projection 4 c.
The elastic member 5 has a spout portion 10, a mounting portion 20 connected to the spout portion 10 and mounted to the adaptor body 4, and a base portion 30 connected to the mounting portion 20. The elastic member 5 is made of a soft material such as silicon in order to adapt the infant to the drinking spout portion 10.
The base portion 30 is flat as a whole, and is disposed between the top wall portion 4b of the adapter body 4 and the annular upper end surface 2a defining the opening of the container body 2. The base 30 expands along the top wall portion 4b of the adapter body 4, forming a seal between the top wall portion 4b and the upper end face 2a of the container body 2. More specifically, the base 30 includes a 1 st surface 31 that forms a seal portion by contacting the adapter body 4, and a 2 nd surface 32 that is provided opposite the 1 st surface 31 and forms a seal portion by contacting the upper end surface 2a of the container body 2. A base opening 33 communicating with the internal space of the container main body 2 is provided substantially at the center of the base 30.
The mounting portion 20 is cylindrical as a whole and stands upright so as to surround the base opening 33 upward from the base 30. The mounting portion 20 penetrates the mounting hole 4h of the adapter body 4. An extending projection 21 extending outward of the mounting hole 4h is formed at the upper end portion of the mounting portion 20 when viewed in a direction (vertical direction) from the top wall portion 4b of the adapter body 4 toward the plate-like portion. As shown in fig. 4, the extending projection 21 is disposed on the opposite side of the top wall portion 4b of the adapter main body 4 from the base portion 30 side, in other words, by disposing an edge portion of the mounting hole 4h defining the top wall portion 4b between the base portion 30 and the extending projection 21, thereby holding the elastic member 5 to the adapter main body 4.
The spout portion 10 covers the upper end of the cylindrical mounting portion 20. The spout portion 10 has a flat plate portion 11 disposed facing the base portion opening 33. If the user sucks, the flat plate-like portion 11 is elastically deformed. The flat plate portion 11 is provided with a slit 7. The slit 7 is opened by elastic deformation of the flat plate-like portion 11. Therefore, if the user sucks the flat plate-like portion 11 and elastically deforms the flat plate-like portion 11, the slit 7 is opened. Therefore, if the user tilts the beverage container 1 in a state where the flat plate portion 11 sucks, the beverage in the container main body 2 flows out through the slit 7, and the user can drink the beverage. By discharging the beverage through the slit 7, the flow rate per unit time of the beverage discharged from the container body 2 can be suppressed, and the infant can take the beverage appropriately.
The flat plate portion 11 has an outer surface 12 to be sucked by a user and an inner surface 13 which is a side of the container body 2 (opposite to the outer surface 12). As shown in fig. 3, 5, and 8, the linear rib 8 is provided on the inner surface 13. The slit 7 is provided in the linear rib 8. The linear rib 8 effectively prevents the flat plate portion 11, particularly, the portion where the slit 7 is provided from being bent outward of the container body 2. Therefore, when the beverage container 1 is tipped over, it is possible to effectively prevent the flat plate portion 11 from being bent outward of the container body 2 by the pressure of the beverage in the beverage container 1, and the slit 7 from being opened, thereby preventing the beverage in the beverage container 1 from unintentionally leaking. Further, it is possible to effectively prevent the flat plate portion 11 from being bent outward of the container main body 2 by the internal pressure and opening the slit 7, and thus the beverage in the beverage container 1 from leaking out unintentionally, when the internal pressure of the container main body 2 is increased by pouring a hot beverage into the container main body 2 or taking the beverage container 1 stored in the refrigerator out of the refrigerator. On the other hand, the linear rib 8 does not significantly restrict the flat plate-like portion 11 from flexing inward of the container body 2. Therefore, by a simple operation such as sucking in the flat plate-like portion 11, the flat plate-like portion 11 can be bent toward the inside of the container body 2 to open the slit 7, whereby the beverage in the container body 2 can be drunk. By using the beverage container 1 having such a flat plate portion 11, training for drinking beverages from a container for infants and training for drinking beverages can be promoted.
As shown in fig. 1, the linear rib 8 is provided at the center of the flat plate-like portion 11 in a direction D2 perpendicular to the longitudinal direction D1 of the linear rib 8. This can more effectively prevent the flat plate-like portion 11 from being bent outward of the container body 2. Therefore, when the beverage container 1 is toppled over, or when the internal pressure in the container body 2 rises, or the like, it is possible to more effectively prevent the flat plate-like portion 11 from being bent outward of the container body 2 to open the slit 7, and thus prevent the beverage in the beverage container 1 from unintentionally leaking out.
As shown in fig. 2 and 4, the flat plate-like portion 11 is inclined with respect to an opening surface (a surface surrounded by the upper end surface 2a of the container body 2) defined by the container body 2. More specifically, the edge portion 11a of the flat plate-like portion 11 on one side in the longitudinal direction D1 of the linear rib 8 is located farther from the top wall portion 4b of the adapter main body 4 than the edge portion 11b of the flat plate-like portion 11 on the other side. This makes it easy to place the upper lip on the one edge 11a of the flat plate portion 11, and drink the beverage in the container body 2. This can further promote the training of the infant to drink the beverage from the container, and further promote the training of the drink.
Specifically, the spout portion 10 has an upright upper wall portion 15 that rises from an edge portion 20a of the attachment portion 20 that is one side in the longitudinal direction D1 of the linear rib 8. The upright upper wall portion 15 is connected to an edge portion 11a of the flat plate-like portion 11 that is one side in the longitudinal direction D1 of the linear rib 8. The upright upper wall portion 15 extends in a non-parallel, more specifically, vertical direction with respect to the flat plate-shaped portion 11 between the edge portion 11a of the flat plate-shaped portion 11 and the edge portion 20a of the attachment portion 20. On the other hand, the edge portion 11b of the flat plate-like portion 11 on the other side in the longitudinal direction D1 is directly connected to the attachment portion 20. Thereby, the flat plate portion 11 is inclined with respect to the opening surface defined by the container main body 2. The vertical upper wall portion 15 is provided, so that the position of the mouth of the user can be visually guided to the vertical upper wall portion 15 side (hence, the side of the edge portion 11a of the flat plate-like portion 11). This can promote the training of the infant to drink the beverage from the container, and can further promote the training of the drink. Side wall portions 16 and 16 are provided between the edge portion 11c of the flat plate portion 11 and the edge portion of the attachment portion 20, which are on one side and the other side in the direction D2 perpendicular to the longitudinal direction D1 of the linear rib 8.
As shown in fig. 1 and 2, a linear protruding portion 17 extending along an edge portion 11a of the flat plate-like portion 11 that is one side in the longitudinal direction D1 of the linear rib 8 (and therefore extending in a direction not parallel to the longitudinal direction D1 of the linear rib 8) is provided at the edge portion 11 a. The linear protruding portion 17 protrudes from the edge portion 11a toward the outside of the container main body 2 substantially along the rising direction of the standing upper wall portion 15. By providing the linear protruding portion 17, the edge portion 11a of the flat plate-like portion 11 can be gripped easily. This also allows the position of the user's mouth to be guided to the linear protruding portion 17 side (hence, the edge portion 11a side of the flat plate-like portion 11). Further, training of drinking a beverage from the container can be promoted, and training of drinking a beverage can be further promoted.
As shown in fig. 1, the linear protrusion 17 has a concave portion 18 at a position overlapping the slit 7 in a direction D2 perpendicular to the longitudinal direction D1 of the slit 7. Thereby, when the linear protrusion 17 sucks the beverage, the beverage flowing out of the slit 7 is guided into the mouth of the user through the recess 18 of the linear protrusion 17. This also allows the user to guide the position of the mouth to the position of the recess 18 (hence, the side of the edge portion 11a of the flat plate-like portion 11). Further, training of drinking a beverage from the container can be promoted, and training of drinking a beverage can be further promoted.
In the illustrated example, the spout portion 10, the mounting portion 20, and the base portion 30 are integrally formed. By integrally forming the respective portions 10, 20, and 30 having different functions in this manner, the number of parts of the beverage container 1 can be reduced, and the workability in 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 and 7 to 9, the lid 6 has a dome shape and covers the spout portion 10 in a closed state. By covering the spout portion 10 with the cover 6, the spout portion 10 can be kept sanitary. As can be understood from fig. 1, 4, and 7, the lid 6 is connected to the mouthpiece adaptor 3 so as to be swingable, and is opened and closed by a relative movement with respect to the mouthpiece adaptor 3. More specifically, the cover 6 is connected to the edge portion of the adapter main body 4 that is the other side of the slit 7 in the longitudinal direction D1. In the illustrated example, the pivot axis Ax of the cover 6 is orthogonal to the longitudinal direction D1 of the slit 7. This prevents the lid 6 from interfering with the operation of drinking the beverage when the lid 6 is opened and the beverage is drunk from the beverage container 1.
The lid 6 has an inner surface 6a facing the spout 10 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 is provided with a leakage prevention mechanism 50 for preventing leakage of the beverage from the spout 10 when the lid 6 is closed. The liquid leakage preventing mechanism 50 is provided on the inner surface 6 a. The leakage preventing mechanism 50 includes a restricting portion 51 that restricts the flat plate-shaped portion 11 from bulging outward of the container body 2, a pressing portion 52 that presses the flat plate-shaped portion 11 to suppress the opening of the slit 7, and a contact portion 53 that contacts the flat plate-shaped portion 11 to bend the flat plate-shaped portion 11 inward of the container body 2.
As shown in fig. 1 and 7 to 9, the restricting portion 51 protrudes from the inner surface 6a of the cover 6, and contacts the flat plate portion 11 in a state where the cover 6 is closed, thereby restricting the flat plate portion 11 from bulging toward the cover 6. More specifically, in the closed state of the cover 6, the restriction portion 51 contacts the edge portion 11b of the flat plate-like portion 11 in the direction D2 orthogonal to the longitudinal direction D1 of the slit 7 in the flat plate-like portion 11 with the portion 11D between the slits 7, and restricts the portion 11D from bulging toward the cover 6 side. In the illustrated example, the restricting portion 51 includes a plurality of plate-shaped restricting projections (the 1 st restricting projection 51a and the 2 nd restricting projection 51b) that are arranged separately along the longitudinal direction D1 of the slit 7. The restricting projections 51a, 51b extend linearly in a direction D2 perpendicular to the longitudinal direction D1 of the slit 7 in the closed state of the lid 6. The regulating projections 51a and 51b are located in a region overlapping the slit 7 in the longitudinal direction D1 of the slit 7 in the state where the cover 6 is closed. This prevents the flat plate-like portion 11 from being bent toward the cover 6 on both sides of the slit 7 and opening the slit 7.
As shown in fig. 1, 7, and 8, the pressing portion 52 protrudes from the inner surface 6a of the cover 6, and contacts the flat plate portion 11 in a state where the cover 6 is closed, thereby suppressing the opening of the slit 7. More specifically, the pressing portion 52 presses the flat plate-like portion 11 in a direction not parallel to the longitudinal direction D1 of the slit 7, more specifically, in a direction closing the slit 7 in a state where the cover 6 is closed.
As shown in fig. 1 and 8, the pressing portion 52 includes a pair of pressing projections 52a, 52 a. In the illustrated example, the pair of pressing protrusions 52a and 52a are connected to both sides of the 1 st regulating protrusion 51 a. The pressing projections 52a and 52a have a greater length projecting from the cover 6 than the 1 st regulating projection 51 a. The length of each of the pressing protrusions 52a and 52a protruding from the cover 6 is gradually increased along a direction D2 perpendicular to the longitudinal direction D1 of the slit 7 as the pressing protrusion is separated from the 1 st regulating protrusion 51 a. Therefore, the pressing force can be effectively applied to the flat plate-like portion 11 from the pair of pressing protrusions 52a, 52 a. In other words, the pressing projections 52a and 52a press the other portions (portions other than the flat plate-shaped portion 11) of the spout portion 10, and the flat plate-shaped portion 11 is prevented from being deformed to the cover 6 side to open the slit 7.
The pair of pressing projections 52a, 52a press the edge portions 11c, 11c of the flat plate-like portion 11 on one side and the other side in the direction D2 orthogonal to the longitudinal direction D1 of the slit 7 in the direction not parallel to the longitudinal direction D1 in the state where the cover 6 is closed. More specifically, the pair of pressing projections 52a, 52a press the side walls 16, 16 of the spout portion 10 in the orthogonal direction D2. Thereby, the pressing projections 52a, 52a can effectively close the slit 7. The pair of pressing projections 52a, 52a are located in a region overlapping the slit 7 in the longitudinal direction D1 of the slit 7 in the state where the cover 6 is closed. Therefore, if the pair of pressing protrusions 52a, 52a presses the flat plate-like portion 11 in a state where the cover 6 is closed, the pair of surfaces 7a, 7a defining the slit 7 are pressed against each other. This effectively suppresses the opening of the slit 7.
As shown in fig. 1, 7, and 9, the contact portion 53 protrudes from the inner surface 6a of the cover 6, and is pressed toward the container body 2 by being in contact with the flat plate portion 11 in a state where the cover 6 is closed. When the cover 6 is closed, the contact portion 53 contacts the center of the flat plate-like portion 11 in the direction D2 perpendicular to the longitudinal direction D1 of the slit 7. Therefore, the flat plate-like portion 11 can be flexed inward of the container body 2 so that the center of the flat plate-like portion 11 in the orthogonal direction D2 becomes a valley. This can effectively prevent the tabular portion 11 from bulging toward the cover 6 side in the state where the cover 6 is closed. The contact portion 53 is in contact with a portion of the flat plate-like portion 11 that is deviated from the slit 7 in the longitudinal direction D1 in the state where the cover 6 is closed. Therefore, the contact portion 53 is prevented from entering the slit 7 and opening the slit 7 in a state where the cover 6 is closed.
The restricting portion 51, the pressing portion 52, and the contact portion 53 are formed integrally with the cover 6. This can effectively prevent the relative position between the cover 6 and the liquid leakage preventing mechanism 50 from being displaced. Therefore, the relative position of each part 51, 52, 53 of the leakage preventing mechanism 50 and the spout 10 can be effectively prevented from being displaced. As a result, leakage of liquid from the spout portion 10 can be stably prevented. In addition, the number of parts of the beverage container 1 can be reduced to improve the operability in cleaning.
According to the above-described embodiment, the beverage container 1 includes: a container main body 2; and a spout adaptor 3 having a spout portion 10 elastically deformed by being sucked by a user and attached to the container body 2. The spout portion 10 includes a flat plate portion 11 having a linear rib 8 on a surface 13 on the container body 2 side. The flat plate portion 11 is provided with the slit 7 opened by the elastic deformation in the linear rib 8.
According to the beverage container 1, the linear rib 8 of the flat plate portion 11 provided on the container body 2 side can effectively prevent the flat plate portion 11 from being bent outward of the container body 2. Therefore, when the beverage container 1 is toppled over, when the internal pressure of the container main body 2 is increased, or the like, it is possible to effectively prevent the flat plate-shaped portion 11 from being bent outward to open the slit 7, and the beverage in the beverage container 1 from unintentionally leaking out of the spout. On the other hand, the flat plate-like portion 11 is not greatly restrained by the linear rib 8 from flexing inward of the container body 2. Therefore, by a simple operation such as sucking in the flat plate-like portion 11, the flat plate-like portion 11 can be bent toward the inside of the container body 2 to open the slit 7, whereby the beverage in the container body 2 can be drunk. Such a beverage container 1 can promote the infant to drink the beverage from the container, and further promote the training of the drinking.
In the above specific example, the linear rib 8 is provided at the center of the flat plate-like portion 11 in the direction D2 perpendicular to the longitudinal direction D1 of the linear rib 8. This can more effectively prevent the flat plate-like portion 11 from being bent outward of the container body 2. Therefore, when the beverage container 1 is tilted, when the internal pressure of the container body 2 rises, or the like, it is possible to further effectively prevent the flat plate-like portion 11 from being bent to the outside of the container body 2 and opening the slit 7, and thus prevent the beverage in the beverage container 1 from unintentionally leaking out of the spout.
In the above-described specific example, the flat plate-like portion 11 is inclined with respect to the opening surface defined by the container main body 2. This makes it easy to place the upper lip on the flat plate portion 11, and drink the beverage. This also promotes the infant to drink from the container, thereby promoting the training of the drinking.
In the above specific example, the spout portion 10 further includes the upright upper wall portion 15 which is connected to the edge portion 11a of the flat plate-shaped portion 11 which is one side in the longitudinal direction D1 of the linear rib 8 and is not parallel to the flat plate-shaped portion 11. This allows the position of the user's mouth to be visually guided to the edge portion 11a side of the flat plate-like portion 11. This can promote the infant to drink the beverage from the container, and further promote the training of the drinking.
In the above specific example, the linear protruding portion 17 is provided at the edge portion 11a of the flat plate-like portion 11 that is one side in the longitudinal direction D1 of the linear rib 8. This makes it easy to grip the edge 11a of the flat plate-like portion 11. This allows the position of the user's mouth to be guided to the edge portion 11a side of the flat plate-like portion 11. Therefore, the infant can be promoted to drink the beverage from the container, and the training of the sucking can be promoted.
In the above-described specific example, the beverage container 1 further includes the lid 6 that covers the spout portion 10 in a closed state and can be opened and closed. The cover 6 has a pressing portion 52 that is in contact with the flat plate-shaped portion 11 in the closed state and presses the flat plate-shaped portion 11 in a direction not parallel to the longitudinal direction D1 of the slit 7. This can prevent the flat plate-like portion 11 from being pressed in the direction of closing the slit 7 when the cover 6 is closed, thereby preventing the slit 7 from being opened. Therefore, the beverage can be effectively prevented from leaking from the slit 7.
In the above specific example, the pressing portion 52 is located in a region overlapping the slit 7 in the longitudinal direction D1 of the slit 7 in the state where the cover 6 is closed. This enables the cover 6 to be effectively pressed against the pair of surfaces 7a and 7a defining the slit 7 when closed, thereby effectively suppressing the opening of the slit 7. Therefore, the leakage of the beverage from the slit 7 can be further effectively prevented.
In the above-described specific example, the linear protruding portion 17 extending along the edge portion 11a of the flat plate-like portion 11 that is one side in the longitudinal direction D1 of the slit 7 is provided. The linear protrusion 17 is provided with a recess 18 at a position overlapping the slit 7 in a direction D2 perpendicular to the longitudinal direction D1 of the slit 7. Thereby, when the linear protrusion 17 sucks the beverage, the beverage flowing out of the slit 7 is guided to the mouth of the user through the recess 18 of the linear protrusion 17. This also allows the user to guide the position of the mouth to the position of the recess 18 (hence, the side of the edge portion 11a of the flat plate-like portion 11). Further, the training of drinking the beverage from the container and the training of drinking the beverage can be promoted.
In the above-described specific example, the cover 6 further includes the regulating portion 51 that, in the closed state of the cover 6, contacts the portions 11D, 11D between the slits 7 that become the edge portions 11c, 11c of the flat plate-like portion 11 in the direction D2 orthogonal to the longitudinal direction D1 of the slits 7 in the flat plate-like portion 11 to regulate the bulging of the portions 11D, 11D. This can effectively prevent the flat plate-like portion 11 from being bent toward the cover 6 on both sides of the slit 7 and opening the slit 7 when the cover 6 is closed. Therefore, the beverage can be effectively prevented from leaking from the slit 7.
In the above-described specific example, the regulating portion 51 is located in a region overlapping the slit 7 in the longitudinal direction D1 of the slit 7 in the state where the cover 6 is closed. This can further effectively prevent the flat plate-like portion 11 from being bent toward the cover 6 on both sides of the slit 7 when the cover 6 is closed and the slit 7 from being opened. Therefore, the beverage can be further effectively prevented from leaking from the slit 7.
In the above-described specific example, the regulating portion 51 includes the linear regulating protrusion 51a extending in the direction D2 orthogonal to the longitudinal direction D1 of the slit 7 in the closed state of the lid 6. With such a restricting projection 51a, the tabular portion 11 can be effectively suppressed from bulging toward the cover 6 side in a state where the cover 6 is closed. Therefore, it is possible to further effectively prevent the opening of the slit 7 and to prevent the beverage from leaking from the slit 7.
In the above-described specific example, the pressing portion 52 includes a pair of pressing protrusions 52a, 52a connected to both sides of the regulating protrusion 51a, respectively, and having a length protruding from the cover 6 greater than the regulating protrusion 51 a. When the flat plate-like portion 11 is pressed by the pair of pressing projections 52a and 52a in a state where the cover 6 is closed, the slit 7 can be effectively closed from both sides thereof. As a result, the beverage can be effectively prevented from leaking from the slit 7.
In the above-described specific example, the length of the pressing projection 52a projecting from the cover 6 gradually increases as it separates from the regulating projection 51a in the direction D2 orthogonal to the longitudinal direction D1 of the slit 7. With the pair of pressing protrusions 52a, the pressing force can be effectively applied to the flat plate-like portion 11 with the cover 6 closed. In other words, the pressing projections 52a and 52a press the other portions (portions other than the flat plate portion 11) of the drink opening portion 10 to deform the flat plate portion 11 so as to be bent toward the lid 6 side, thereby preventing the slit 7 from being opened. Therefore, the beverage can be effectively prevented from leaking from the slit 7.
In the above specific example, the regulating portion 51 includes a plurality of regulating projections 51a and 51b arranged apart from each other along the longitudinal direction D1 of the slit 7. Thus, in the state where the cover 6 is closed, the tabular portion 11 can be effectively prevented from bulging toward the cover 6, and the opening of the slit 7 can be effectively suppressed. Therefore, the beverage can be effectively prevented from leaking from the slit 7.
In the above specific example, the cover 6 has the contact portion 53 that contacts the portion of the flat plate-like portion 11 that is deviated from the slit 7 along the longitudinal direction D1 of the slit 7 in the closed state. Such a contact portion 53 allows the flat plate-like portion 11 to be flexed inward of the container body 2. Therefore, when the lid 6 is closed, the flat plate-like portion 11 can be suppressed from being bent toward the lid 6 (outside the container body 2). The contact portion 53 is in contact with a portion of the flat plate-like portion 11 that is deviated from the slit 7 in the longitudinal direction D1 in the state where the cover 6 is closed. Therefore, the contact portion 53 can be prevented from entering the slit 7 and opening the slit 7 in a state where the cover 6 is closed. As described above, the beverage can be effectively prevented from leaking from the slit 7.
In the above specific example, the beverage container further includes a lid 6 that covers the spout portion 10 in a closed state and can be opened and closed. The lid 6 is connected to the mouthpiece adapter 3 so as to be swingable, and the swing axis of the lid 6 is perpendicular to the longitudinal direction D1 of the slit 7. By covering the spout portion 10 with the cover 6, the spout portion 10 can be kept sanitary. Further, when the lid 6 is opened and the beverage is drunk from the beverage container 1, the lid 6 is prevented from hindering the operation of drinking the beverage.
In the above specific example, the mouthpiece 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 spout portion 10, a mounting portion 20 connected to the spout portion 10 and mounted to the adaptor body 4, and a base portion 30 connected to the mounting portion 20 and forming a seal with the container body 2. The mouthpiece 10, the mounting portion 20, and the base portion 30 are integrally formed. By integrally forming the portions 10, 20, 30 having different functions, the number of parts of the beverage container 1 can be reduced, and the workability in cleaning can be improved. In addition, the respective parts 10, 20, 30 can be easily assembled to the adapter body 4.
One embodiment is described by a plurality of specific examples, but these specific examples are not intended to limit the one embodiment. The above-described embodiment can be implemented by various other specific examples, and various omissions, substitutions, and changes can be made without departing from the spirit thereof.
Although several modifications of the above embodiment have been described above, it is needless to say that a plurality of modifications may be appropriately combined and used.
