Description

Beverage container

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a beverage container, and more particularly to a beverage container which improves the sealability of the container, prevents leakage of contents, and is provided with a lid that is easy to open.

Usually, when selling a take-away beverage, the beverage is poured into a container such as a cup and then the lid is closed. This is to avoid overflowing the contents of the beverage when the cup is shaken during the take-up. When the lid is closed and the opening of the cup is completely sealed, the liquid contained therein does not overflow. However, when drinking, it is necessary to remove the cover, which is very troublesome. In addition, there may be an overflow when the cover is removed. Once the lid is placed on the container, it is great if you can drink the beverage directly while the lid is closed.

For example, there has been proposed a cup with a lid attached to the lid having a drinking mouth that is elongated like a bird's beak (refer to Patent Document 1). According to the cup of Patent Document 1, a small hole for drinking is formed on the drinking opening protruding from the cover. So even when the lid is covered When the child is traversed or inverted, the liquid (beverage) also hardly flows out of the small hole of the drinking port. However, since the cup of Patent Document 1 is mainly used for infants and young children, the amount of liquid that can flow out from the small holes of the drinking port is extremely small. On the other hand, if the opening amount of the small hole becomes large, the effect of suppressing the outflow of the liquid is lost. From this point of view, although it has a good sealing property to the liquid in the cup, it is not suitable for a general container.

In view of this point, there has been proposed a cover for opening or closing an operation means for injecting an opening of a liquid in a container such as a cup (see Patent Document 2). According to the cover of the structure of Patent Document 2, the injection opening portion of the liquid can be enlarged and the opening and closing type can be opened, so that the convenience of use is improved. However, as the structure of the cover is complicated, the unit price of the product is also likely to rise. If it is mainly based on the cover of Patent Document 2, it is not intended to be discarded, but is premised on being reusable.

At present, most of the beverage containers for outer tapes are in the opening of the container body such as a paper cup, and are covered with a lid body having a projecting portion having a round hole shape. Then, by placing the mouth on the protruding portion, the beverage in the container can be drunk from the outflow hole provided at the end of the protruding portion. However, in the current container, the adhesion between the container body and the lid body is insufficient, and the corresponding prevention of liquid leakage is urgent. In addition, if the beverage is directly drunk while the lid is covered, the height of the protruding portion is added in addition to the height of the container body, so that it is not easy to grasp the tilting angle of the container and the actual feeling of the liquid surface of the beverage. . Especially when the beverage is a hot drink, it is not easy to confirm the dumping condition of the container, and if it is not noticed, it will drink the hot drink.

From this point of view, it has deepened the public's need for a novel container. It is desirable that the beverage in the container does not easily overflow and can be formed with a low price, or even close to the feeling of using a cup to drink a beverage.

The beverage container 1 of the present invention can be seen from the side view of the separated state of Fig. 1, and is composed of the container body 10 and the lid body 50. The beverage container 1 is a container with a lid, which is mainly used for convenience of selling beverages in shops, supermarkets, department stores, restaurants, and the like, and even for buffet forms, foreign exchange, take-out, home delivery services, and the like. The beverage is filled in the container body 10, and the lid 50 is covered and then supplied to the customer. Since the lid body 50 is provided, even if the beverage container 1 is shaken, the beverage of the contents does not easily overflow. Further, there is a feature that the beverage can be easily consumed by the operation of the lid 50 described later. First, the configuration of the beverage container 1 will be described based on the respective drawings.

As shown in FIG. 2 (top view) and FIG. 3 (stereoscopic view), the container main body 10 has an inner peripheral sliding portion 12 formed inside the upper opening 11, and an outer peripheral crotch portion 13 extending outside the inner peripheral sliding portion 12 ( Container flange). The side surface of the container body 10 is a body portion 15, and the bottom surface is a bottom portion 16, and the container body 10 is formed in a cup shape. The inner peripheral sliding portion 12 and the main body portion 15 are connected to each other through the inner circumferential step portion 14. In the inner peripheral sliding portion 12 and the outer peripheral crotch portion 13 of the container body 10, a pouring recess portion 20 formed by a partial recess portion 24 for discharging the beverage from the inside of the container body 10 to the outside is formed. Note that the recess 20 becomes a drink The flow path. In order to allow the beverage to smoothly flow out, the partial recessed portion 24 is formed on both the inner peripheral sliding portion 12 and the outer peripheral crotch portion 13, and is a depression having a slow L shape in cross section (see Figs. 7 and 9).

The injection recesses 20 are formed at two places of the container body 10 in such a manner as to face each other. A 180° opposite position (diameter) disposed on the circumference of the upper opening 11. As will be described later, when the beverage flows through one of the dispensing recesses 20, the other dispensing recess 20 becomes a flow portion of the air. The two injection recesses 20 have the same shape, and are referred to as a first injection recess 21 and a second injection recess 22 for convenience. In Fig. 3, reference numeral 41 is a sleeve receiving portion.

As shown in FIG. 2 and FIG. 4 (stereoscopic view on the back side), the lid body 50 has an inner fitting portion 52 that is detachably attached to the container body 10 so as to be rotatable. The peripheral sliding portion 12 and the outer peripheral crotch portion 13. Further, the lid body 50 is formed with a drinking port communication portion 60 corresponding to the injection recess 20 of the container body 10 by rotating the lid body. The lid body 50 is an inner fitting shape that is fitted into the inner side of the inner peripheral sliding portion 12 of the container body 10. Therefore, the lid portion 51 is pressed downward more than the lid portion 53, and the lid step portion 54 is formed and has the inner fitting portion 52. The illustrated cover 50 is vertically opposed, so the cover portion 51 protrudes outward.

Further, the lid body 50 is formed with a drinking port communication portion 60 corresponding to one of the dispensing recesses 20 (21 or 22). At the same time, an outer air communication portion 61 corresponding to the other injection recess 20 is also formed. The drinking port communication portion 60 serves as a flow path for the beverage, and the external air communication portion 61 serves as a flow path for the air. The drinking port communication portion 60 of the cover 50 is in communication with the outside air The portion 61 is a 180° opposing position (diameter) disposed on the circumference of the fitting portion 52, like the injection recess 20. Since the drinking port communication portion 60 is a flow path of the beverage, it is formed larger than the external air communication portion 61. Specifically, the cover step portion 54 is cut into a curved surface shape. When the drink is served through the drinking port communication portion 60, the lid portion 53 covering the dispensing recess 20 is hindered. Therefore, the opening of the recess portion 20 of the outer peripheral portion 13 can be used to make the lid portion 53 a notch. Department 55 will cut it.

After the lid body 50 is fitted into the container body 10, the injection recessed portion 20 is opened and closed by the rotation of the lid body 50 itself. Therefore, the cover portion 51 of the cover 50 is provided with a rotary grip portion 70 for rotating the cover itself. As can be seen from Fig. 2 and Fig. 4, the rotary grip portion 70 has a rod shape which is bulged at both ends. The user of the beverage container 1 can rotate the lid 50 in a clockwise or counterclockwise direction by placing a finger on the swollen portion 71 at both ends of the rotating grip portion 70. Since the rotating grip portion 70 is provided on the lid portion 51, the rotation of the lid body 50 can be made easier.

Further, the lid body 50 in the drawing is provided with an opening and closing grip portion 75. Since the lid body 50 has a structure having the lid portion 53 , the opening and closing grip portion 75 is provided in the lid portion 53 . The opening and closing grip portion 75 protrudes more outward than the outer peripheral crotch portion 13 of the container body 10 when the fitting portion 75 is fitted. Therefore, when the lid body 50 is covered and fitted to the container body 10, when the lid body 50 is to be removed, The lid body 50 can be easily removed by pulling the opening and closing grip portion 75 upward. For example, it is extremely convenient when adding a drink or the like.

Further, the opening and closing grip portion 75 in the drawing is disposed at an opposing position of the cutout portion 55. If the 锷 notch 55 is matched with one of them When the concave portion 20 is injected, the opening and closing grip portion 75 is positioned in the other injection recess portion 20. In this way, the communication groove 62 is formed in the lid portion 53 of the opening and closing grip portion 75. The communication groove 62 and the external air communication portion 61 are air passages for guiding the air outside the beverage container 1 to the inside of the container body 10, thereby releasing the pressure difference, and facilitating the beverage of the contents from the injection recess 20 and the drinking port communication portion. 60 outflow.

Further, an exhaust portion 65 is formed in the lid body 50 again. The exhaust portion 65 is a vent of water vapor after the lid 50 is covered and fitted into the container body 10. When the hot beverage is loaded into the container body 10 and the lid body 50 is fitted, the generated hot air fills the inside of the beverage container 1. As a result, the pressure inside the container rises, and the cover 50 may fall off if it is accidentally closed. Therefore, a small hole which can reduce the internal pressure of the container is formed as the exhaust portion 65.

Further, although not shown, an arrow or a character (for example, "rotation") or the like for displaying a rotation direction may be added to the lid portion 51 or the rotation grip portion 70 of the lid body 50. In addition, you can also add text from where to drink (such as "drinking mouth"). You can also add appropriate reminder text (such as "hot") for hot drinks. In addition, you can also add a braille or universal design to display these contents.

FIG. 5 is a partially enlarged longitudinal sectional view showing a state in which the inner peripheral sliding portion 12 of the container body 10 is fitted to the inner fitting portion 52 of the lid body 50. The upper side (the upper opening 11 side) of the inner peripheral sliding portion 12 is only slightly narrower than the lower side thereof. Similarly, the upper side of the inner fitting portion 52 is also narrower than the lower side. It can be understood from the schema so far, in order to be free Rotation, the inner peripheral sliding portion 12 and the inner fitting portion 52 have a circular cross-sectional shape. Therefore, each part can be expressed according to its diameter. In other words, the lower diameter Dc1 which becomes the lower end 31 of the inner peripheral sliding portion 12 is formed to be larger than the upper diameter Dc2 (Dc1 > Dc2) which is the upper end 32 of the inner peripheral sliding portion 12. Similarly, the lower diameter Dt1 which becomes the lower end 81 of the inner fitting portion 52 is formed to be larger than the upper diameter Dt2 (Dt1 > Dt2) which becomes the upper end 82 of the inner fitting portion 52.

The shape of the inner peripheral sliding portion 12 and the inner fitting portion 52 is not limited to the shape of the drawing. However, as will be described later, the inner peripheral sliding wall 33 and the inner fitting wall 83 are formed in a wall shape for the convenience of molding. The angle between the inner peripheral sliding portion 12 and the inner fitting portion 52 is approximately 1 to 7 degrees from the vertical axis Ax of the container in the vertical direction toward the inner side of the container. The inclination angle is determined by considering the release film at the time of molding, the ease of fitting the lid body, the shape and size of the container itself, and the like. Further, since the inner fitting wall 83 or the lower end 81 of the inner fitting portion 52 abuts against the inner peripheral sliding wall 33 of the inner peripheral sliding portion 12, the adhesion between them is increased, and the airtightness of the container is improved. . Therefore, the beverage is not easily leaked from the outside of the beverage container 1.

Further, when the beverage container 1 is poured or dropped, the outer peripheral crotch portion 13 of the container body 10 may hit the table or the ground. In this case, the impact force is transmitted from the outer crotch portion 13 to the inner fitting portion 52. Here, as described above, since the upper opening 11 side of the inner peripheral sliding portion 12 of the container body 10 is narrow, the inner fitting portion 52 is pressed toward the lower side of the inner peripheral sliding portion 12 due to the forceful force at the time of collision. On the side, the fitting of the inner peripheral sliding portion 12 and the inner fitting portion 52 is reinforced. Therefore, a cover is fitted to the container body The beverage container behind the body can suppress the leakage of the beverage even if it is impacted by falling or falling.

When the inner fitting portion 52 of the lid body 50 is fitted to the inner peripheral sliding portion 12 of the container body 10, the lid body 50 is less likely to be detached from the container body 10 by accident. Specifically, when the lid body 50 is disengaged, the lower end 81 of the inner fitting portion 52 moves. However, the upper end 32 of the inner peripheral sliding portion 12 exerts a resistance against the lower end 81. Therefore, the movement of the lower end 81 of the inner fitting portion 52 is suppressed, and the lid body 50 can be suppressed from being easily detached. Further, when the lid body 50 is attached to the container body 10, appropriate resistance is generated. However, when the cover 50 is fitted, the inner peripheral sliding portion 12 can be easily and naturally inserted into the inner fitting portion 52 as long as the lower end 81 of the fitting portion 52 in the cover 50 passes through the upper end 32 of the inner peripheral sliding portion 12. . Therefore, the user of the beverage container of the present invention can clearly feel the sense of control from the sound, the sense of touch, the resistance, and the like which are emitted when the cover is fitted, and can easily confirm whether or not the fitting condition is improper.

Next, the state of the present invention at the time of use will be described using Figs. 6 to 9 . Fig. 6 is a plan view of the beverage container 1, and Fig. 7 is a longitudinal sectional view of the beverage container 1. The cover 50 of Fig. 7 is a cross-sectional view corresponding to the line X-X of Fig. 2(a), and the container body 10 is a cross-sectional view corresponding to the Z-Z line of Fig. 2(b). 6 and 7 show a state in which the lid body 50 is fitted and sealed to the container body 10. In particular, when the beverage is being sold, the beverage is not easily leaked. In the container body 10 of Fig. 6, any of the partial recesses 24 of the recessed portion 20 is covered by the lid portion 53 of the lid body 50.

Further, as shown in FIG. 7, the portion formed in the inner peripheral sliding portion 12 The recessed portion of the recessed portion 24 is not provided in the upper and lower directions of the inner peripheral sliding wall 33, but is provided at a position other than the vicinity of the lower end 31 of the inner peripheral sliding portion 12 (the lower side of the inner peripheral sliding wall 33). Since the inner peripheral sliding wall 33 is in contact with the inner fitting wall 83 of the inner fitting portion 52 or the lower end 81 thereof, the adhesion between the container body 10 and the lid body 50 is extremely high. Further, the lower end 31 of the inner peripheral sliding portion 12 of the container body 10 is not intermittently connected in a circumferential shape. Therefore, the airtightness of the beverage container can be ensured, and the beverage of the contents does not easily leak from the upper opening.

8 is a plan view of the beverage container 1, and FIG. 9 is a longitudinal sectional view of the beverage container 1. The cover 50 of Fig. 9 is a cross-sectional view corresponding to the Y-Y line of Fig. 2(a), and the container body 10 is a cross-sectional view corresponding to the Z-Z line of Fig. 2(b). 8 and 9 also show a state in which the lid body 50 is fitted to the container body 10. In particular, in order to drink a beverage, the state of the lid 50 is operated. Compared with the previous FIG. 6, the cover 50 is rotated by 90° as shown in FIG. Specifically, the user holds the rotary grip portion 70 with a finger and twists until the crotch portion 55 reaches the position directly above the injection recess portion 20 (partial recess portion 24). As a result, one of the injection recesses 20 (the first recessed portion 21 in the drawing) is exposed from the lid portion 53. Then, the communication groove 62 formed in the lid portion 53 is positioned directly above the other injection recess 20 (in the drawing, the second injection recess 22).

As seen from the next FIG. 9, the drinking port communication portion 60 formed in the cover step portion 54 of the lid body 50 is a partial recess portion 24 that faces the injection recess portion 20 (the first injection recess portion 21). In this way, from the inside of the beverage container 1, through the drinking port communication portion 60, the injection recess 20, all the way to the outside The circumference 13 forms a flow path for the beverage. In other words, when the user of the beverage container 1 drinks the beverage, the mouth is attached to the peripheral portion 13 outside the position of the injection recess 20 adjacent to the notch portion 55, and the beverage container 1 is tilted, and the internal beverage naturally flows in. In the mouth (refer to the arrow Ao in the figure). At the same time, the outer air communication portion 61 formed in the cover step portion 54 of the lid body 50 faces the partial recess portion 24 of the injection recess portion 20 (the second injection recess portion 22). Further, the upper end of the partial recessed portion 24 is formed until the middle of the outer peripheral flange portion 13. In this way, a flow path of air (see an arrow Ai in the drawing) is secured from the outside of the beverage container 1, through the communication groove 62, the partial recess 24, and up to the external air communication portion 61. . That is, there is no pressure difference between the inside and the outside of the beverage container 1, and the beverage can smoothly flow out.

When the beverage in the beverage container 1 is left over, the lid body 50 is rotated again until the position where the recessed portion 20 is not seen from the cutout portion 55, and the lid recess 50 is rotated again to close the injection recess 20. In this way, the user can drink the beverage in the beverage container 1 at any time. Further, the outer peripheral crotch portion 13 beside the recessed portion 20 is also covered by the lid portion 53 of the lid body 50, since it is free from exposure and is more sanitary.

The beverage container described so far has a lid formed of a molded article of a known resin sheet, and specifically, polyethylene, polypropylene, polystyrene, or polyethylene terephthalate can be used. A synthetic resin sheet such as an ester (PET) or a biodegradable synthetic resin sheet such as polylactic acid. The thickness of the synthetic resin sheet is preferably about 1.5 mm or less. These synthetic resin sheets are formed by vacuum forming The shape of the cover of the drawing.

There is no special regulation as to the material of the container body as long as it can ensure the shape of the drawing. For example, it can be made of paper, wood, metal, or other resin. Among them, a molded article of a known resin sheet similar to the lid may be used. Then, the shape of the container body of the drawing is formed by vacuum forming.

By making both the container body and the lid body a molded article of the above resin sheet, in addition to reducing the material cost, it can be mass-produced, and the manufacturing unit price can be lowered. Therefore, it can be used as a disposable (disposable) type beverage container for use in take-out. It is more hygienic because it can only be used once.

There is no particular limitation on the type of beverage to be filled into the detailed beverage container. Refreshing beverage water such as water, juice or carbonated beverages, milk beverages, alcoholic beverages, bartending, and other regional specialty beverages are available. As described above, as long as the operation is simple, the liquid leakage can be suppressed even in the case of leftover, and the convenience is extremely high. Among them, it can also be applied to: coffee, black tea, various teas, cocoa, hot chocolate, hot milk, mulled wine, other heated wines, and even soup containers. When it is a cold drink, you can drink it by simply inserting a straw on the lid. However, in the case of a hot beverage, it is rare to use a straw to drink, but to drink directly from the beverage container (cup).

When it is used as a hot drink container, it can prevent the beverage from penetrating through the lid and leaking from the outside of the beverage container. Sealing, so it is extremely convenient. Further, as can be understood from Fig. 9 and the like, the lid body is fitted to the inner side of the container body, so that the height of the beverage container itself and the container body hardly change. That is to say, when the user drinks a beverage, it does not feel that the inclination of the beverage container is different from the actual liquid level of the beverage. In particular, when the user drinks a hot drink, since the degree of tilting the beverage container is the same as that of the container body, it is possible to effectively solve the problem that the excessive tilt causes the beverage to overflow, and it is inconvenient to drink the hot drink accidentally.

The structural cross-sectional view of Fig. 10 shows a state in which the sleeve 40 is attached to the main body portion 15 of the container body 10 to cover the outer peripheral surface of the main body portion 15. The sleeve 40 is a conical trapezoidal cylinder that comes into contact with the sleeve receiving portion 41 that protrudes in a stepped manner. The sleeve 40 and the sleeve receiving portion 41 can be joined by an adhesive, a double-sided tape or the like as needed. Therefore, a gap 42 is formed between the sleeve 40 and the body portion 15 of the container body 10. When the container body 10 is formed of a resin sheet, since the thickness of the resin sheet is thin, the heat of the hot drink is transmitted to the user's hand through the body portion 15, and the user cannot hold the container body 10 because of the heat. Therefore, when the sleeve 40 is attached to the outer peripheral surface of the main body portion 15, since the gap 42 is interposed, direct heat conduction can be suppressed, and heat is not easily felt when it is taken by hand. Considering the problem of specific heat, the sleeve 40 is made of paper or the like, and then appropriate printing is applied to the surface. Further, when the cold beverage is filled in the container body, the sleeve 40 exerts other effects. Usually, when the iced beverage with ice cubes is filled into the container body, the body portion 15 is frosted. However, since the sleeve 40 is provided, the conduction of the coldness of the cold beverage can be suppressed, and The user does not wet the hand with frosted water droplets, and the beverage container 1 can be held by hand.

Fig. 11 is a partially enlarged longitudinal sectional view showing a state in which the lid body 50A of another embodiment is fitted to the container body 10. In the drawings, the same reference numerals are used for the parts common to the cover 50 described above. In the lid body 50A, an auxiliary step portion 56 is provided on the lid surface portion 51 of the lid body 50A. In the drawing, the auxiliary step portion 56 is provided in the cover step portion 54 which is lowered from the lid portion 51. The auxiliary step portion 56 is formed at a position on the lid surface portion 51 (the cover step portion 54), and is located slightly inside the inner side of the inner fitting portion 52, except for the drinking port communication portion 60 and the outer air communication portion 61. Formed in an arc shape. The fitting of the inner peripheral sliding portion 12 and the inner fitting portion 52 is stronger and more stable. By adding the auxiliary step portion 56, a portion having a step difference between the inner peripheral step portion 14 below the inner peripheral sliding portion 12 and the main body portion 15 (in the drawing, the sleeve receiving portion 41) is A void is formed. Therefore, the fitting performance can be improved. Further, the structural strength of the lid body 50 is increased by the auxiliary step portion 56, and resistance to bending deformation is also generated. Further, the structure in which the fitting portion of the lid body of the inner peripheral sliding portion of the container body can be detachably fitted and rotatably attached is not limited to the illustrated structure, and a known fitting structure can be employed. For example, the both sides have a multi-segment structure in which a convex portion and a concave portion are combined.
