  In this type of beverage container, it is easy to suck the contents in the container, but when the milk is heated and stored, or when used in a high-temperature atmosphere in the summer, the air in the container becomes high in pressure and the lid There is a risk of the contents overflowing from the mouth when the body is removed.

  In consideration of such a point, a beverage container that can reduce the increased internal pressure has been proposed. (For example, see Patent Document 1)

The beverage container includes a container body having an upper end opening, a cap body with a nozzle fitted to the container body mouth portion, and a lid body that can be opened and closed on the cap body. A communication hole for communicating the inside and outside of the body is formed, and a closure plug is provided for movably mounting the surface of the lid and closing the communication hole so that the communication hole can be opened and closed.
JP 2005-280714 A

  The above beverage container is superior in that it can reliably prevent inconveniences such as the liquid coming out of the nozzle by being decompressed if the plug is removed from the communication hole in use even if the internal pressure of the container rises due to the temperature change of heated stored items or outside air However, there is a risk that the user may forget to remove the obturator. In addition, in this type of beverage container, there may be a problem that food in the mouth or the like flows backward into the container through the suction nozzle when the stored liquid is sucked. Therefore, the present invention has been made in view of the above points, and proposes a beverage container that can automatically perform a decompression process when the internal pressure increases and can cope with a decrease in internal pressure. Further, the present invention proposes an excellent beverage container that can perform a decompression process during a series of opening operations and never forget the operation, and can more reliably prevent inconveniences such as the content liquid jumping out. Furthermore, a beverage container is proposed that can reliably prevent inconveniences such as food in the mouth flowing back into the container through the suction nozzle.

  The beverage container of the present invention has a form in which the stored liquid can be sucked by the suction nozzle, and the suction nozzle can be folded and closed by the lid plate and stored, and the internal pressure and atmospheric pressure of the container body can be stored. An internal pressure adjustment valve is provided to achieve an equilibrium state.

  The internal pressure adjustment valve is a reversible valve that is decompressed to the outside when the internal pressure of the container rises, and is pressurized to the inside when the internal pressure of the container decreases. Although it is preferable to adopt, it is not limited to this. When the slit valve is employed, there may be one slit or a plurality of slits, and various shapes such as a radial shape may be employed for the plurality of slits.

  In addition, when a slit valve is employed, the slit may be difficult to open in some state. For this purpose, it is preferable to provide a valve opening promoting mechanism that promotes valve opening. As the valve opening promoting mechanism, a method of opening the slit by deforming the valve body on which the slit valve is formed may be employed. Various concrete means can be selected.

  The valve opening promoting mechanism needs to be configured to act on the slit valve by moving the lid plate in the opening direction while the suction nozzle is bent and closed. Therefore, it is preferable that the suction nozzle bends and is closed by the cover plate so that the cover plate can be kept sufficiently closed for a while after the cover plate opens in the opening direction. For this purpose, the suction nozzle is bent and closed by the cover plate. It is preferable to employ a clamping means that clamps the suction nozzle with a lid plate such as a protruding piece in the illustrated example when stored.

  Further, in order to bend and close the suction nozzle and store it, the top wall portion of the cap body is formed in a dome shape, and the lid plate is configured to rotate along the outer surface of the top wall portion. Good storage.

  Although the use of synthetic resin is mainly considered as a material for forming the beverage container, the suction nozzle portion or the valve member portion forming the internal pressure adjusting valve is formed of a flexible and elastic material such as an elastomer. . Further, other materials such as glass can be selected for the container body and the like.

  The first means is configured as follows. That is, a container body A having an upper end opening, a cap main body B that is airtightly fitted to the container body mouth portion, and an elastic deformation in which the upper end portion protrudes upward from the cap main body B so that the contents stored in the container body can be sucked. Beverage container provided with possible suction nozzle 51, and lid plate F provided so that it can be opened and closed between a state in which the suction nozzle 51 can stand and suck and a state in which the tip of the suction nozzle 51 is folded and closed In addition, an internal pressure adjusting valve 57 that equilibrates the internal pressure of the container body A with the atmospheric pressure is provided, and a backflow prevention valve is provided in the suction nozzle 51.

  The second means is configured as follows. That is, in the first means, the internal pressure adjusting valve 57 is a slit valve facing the top wall portion 12 of the cap body B.

  The third means was configured as follows. That is, in the first means, the internal pressure adjusting valve 57 faces the top wall portion 12 of the cap body B so as to be swingable, and is a cylindrical valve body 52 formed of a flexible and elastic material. And a valve opening promoting mechanism for urging the opening of the internal pressure regulating valve 57 by deforming the upper end of the valve body 52 when the cover plate F is opened.

  The fourth means is configured as follows. That is, in the third means, the top of the valve body 52 is formed in the hemispherical top plate 55, and the internal pressure adjusting valve 57 is formed by drilling a slit 56 in the hemispherical top plate 55. The promotion mechanism is configured as a hemispherical protrusion 61 that protrudes from the back surface of the cover plate F in a state where the tip end portion of the suction nozzle 51 is folded and closed, and is fitted on the hemispherical top plate 55.

  The fifth means is configured as follows. That is, in any one of the first to fourth means, the backflow prevention valve is configured by forming the slit 54 at the closed end of the suction nozzle 51.

  The sixth means is configured as follows. That is, in any one of the first to fifth means, the top wall portion 12 of the cap body B is formed in a dome shape, and the storage recess 13 is recessed in a part of the top wall portion 12. The cover plate F can be opened and closed from the state in which the upper end opening of the storage recess 13 is closed to the state in which the upper end opening of the storage recess 13 is opened, and the cover plate F stands up from the storage recess 13 when the cover plate F is closed. A holding means for closing and holding the provided suction nozzle 51 with the cover plate F was provided.

  Since the beverage container of the present invention is provided with the internal pressure adjusting valve 57 that brings the internal pressure of the container body A into equilibrium with the atmospheric pressure, the internal pressure of the container body A rises due to various causes such as the temperature of stored items and the temperature of the outside air. In this case, the pressure is automatically reduced from the internal pressure adjusting valve 57, and as a result, it is possible to reliably prevent inconveniences such as the liquid jumping out from the suction nozzle 51 when the stored item is sucked. In addition, when the internal pressure decreases due to a decrease in the stored items due to suction, it is possible to prevent inconvenience such as the outside air being introduced from the internal pressure adjusting valve 57 and the container body A being recessed. In addition, since a backflow prevention valve is provided, it is possible to prevent intrusion of dust and the like from the tip of the suction nozzle 51, and the liquid sucked into the suction nozzle 51 is not returned to the container body A, and further, Inconveniences such as backflow of food into the container can be prevented, and contamination of the liquid in the container can be prevented as much as possible.

  In addition, when the internal pressure adjusting valve 57 is configured as a slit valve facing the top wall portion 12 of the cap body B, the structure is simple, and there is an effect that the occupied space for it can be reduced. It also works together.

  The internal pressure regulating valve 57 is a slit valve provided on the top of a cylindrical valve body 52 formed of a flexible and elastic material so as to swing on the top wall 12 of the cap body B, When a valve opening promoting mechanism for deforming the upper end of the valve body 52 to open the internal pressure adjusting valve 57 during opening operation of the plate F is provided, even if the slit is difficult to open for some reason, The valve can be opened, and the internal pressure can be reliably reduced during a series of operations with the lid opening operation.

  The top of the valve body 52 is formed in a hemispherical top plate 55, and a slit 56 is formed in the hemispherical top plate 55 to form an internal pressure adjusting valve 57. The valve opening promoting mechanism is bent and the tip of the suction nozzle 51 is bent. When configured as a hemispherical projection 61 fitted on the hemispherical top plate 55 while projecting on the back surface of the lid plate F in the closed and stored state, the slit 56 can be opened without difficulty. In addition, when the lid is closed, the slit 56 can be returned to the original state, so that the deformation of the slit 56 can be prevented, and the durability can be further improved.

  When a slit 54 is formed in the closed tip of the suction nozzle 51 to form a backflow prevention valve, the structure is simple, and there is an advantage that suction without a sense of incongruity can be performed.

  The top wall portion 12 of the cap body B is formed in a dome shape, and a storage recess 13 is provided in a part of the top wall portion 12 so that the cover plate F is closed from the state where the upper end opening of the storage recess 13 is closed. 13 is provided so as to be openable and closable so that the upper end opening is opened, and a clamping means for closing and sandwiching the suction nozzle 51 standing from the inside of the storage recess 13 when the lid plate F is closed is provided between the lid plate F and the lid plate F. In this case, since the suction nozzle 51 can be more reliably closed when not in use, it can be reliably prevented from inconvenience such as a liquid being ejected from the suction nozzle 51 when the internal pressure of the container body A is increased.

The front portion of the first cylindrical portion 14 is formed slightly lower than the top wall portion 12 in order to bend the suction nozzle 51 and store it below the cover plate F. Further, a projecting piece 16 is provided on the front surface of the first cylindrical portion as a clamping means for more reliably performing the closing and closing of the suction nozzle 51. Further, a pair of concave grooves 17 in a side view are provided on both sides behind the storage recess 13 so that the width of the storage recess 13 is the same as that of the outer surface and a support plate of the cover plate F is rotatably stored. is doing.

  The seal member C is made of silicon rubber, which is a flexible and elastic material, and has an arc plate-like auxiliary that comes into contact with the lower surface of the container body from the ring-shaped seal portion 30 fitted to the lower surface of the flange portion 11 of the cap body B. A plurality of frame portions 31 are extended in the circumferential direction. When the cap main body B is screwed to the container body A, the lower surface of the seal portion 30 is in pressure contact with the upper end of the peripheral wall 3 of the container body A to provide the liquid tightness of this portion.

  The nozzle member E is formed of silicon rubber, and a suction nozzle 51 is erected above a through hole formed in the substrate 50. A cylindrical valve having a lower end opened in the substrate 50 in parallel with the suction nozzle 51. The body 52 is erected, and a fitting cylinder portion 53 that communicates with the suction nozzle 51 at the upper end from the back surface of the substrate 50 is further suspended. The tip portion of the suction nozzle 51 is closed and a slit 54 is formed to constitute a backflow prevention valve. In addition, an internal pressure adjusting valve 57 in a form in which a slit 56 is formed in a hemispherical top plate 55 is provided at the tip of the valve body 52.

  Then, the suction nozzle 51 is inserted into the first cylindrical portion 14 from the lower end, and the engaging concave groove 58 provided around the outer peripheral lower end portion is engaged with the locking ridge 18 protruding from the first cylindrical portion 14. The engaging ridge 59 in which the valve body 52 is inserted from the lower side of the second cylinder part 1 and protruded at a predetermined position on the outer periphery is provided on the lower end of the inner periphery of the second cylinder part 15. The nozzle member E is mounted on the cap body B in a liquid-tight manner. At this time, the tip of the suction nozzle 51 protrudes above the first tube portion 14 and protrudes above the top wall portion 12 of the cap body B. In addition, a concave portion at the upper end formed by the hemispherical top plate 55 is configured such that a later-described protrusion of the lid plate F is fitted in the closed state of the storage concave portion 13. Furthermore, the upper end of the suction pipe D is liquid-tightly fitted in the fitting cylinder part 53, and the lower end is suspended to the lower part in the container body A.

  The lid plate F has an arc plate shape having the same radius of curvature as the top wall portion 12 of the cap body B, and has a length that closes the upper end opening of the storage recess 13 of the cap body B. Also, fan-plate-like support plates 60 are suspended from the backs of both sides, and the lower end sides of each support plate 60 are pivotally attached to the side plate portions 13c so as to be pivotably mounted. A hemispherical protrusion 61 is provided at a predetermined position on the back surface of the cover plate F so as to be fitted to the upper end of the valve body 52 that forms the internal pressure adjusting valve 57. The protrusion 61 is configured to slide in the guide groove 19 formed in the cap body top wall portion 12 when the cover plate F is rotated rearward. 1 is provided so as to be openable and closable from the state in which the storage recess 13 in FIG. 1 is closed to the state in which the storage recess 13 in FIG. 3 is completely opened. On the upper surface of the cover plate F, a finger hooking projection 62 is provided.

  In the beverage container 1 configured as described above, in the state of FIG. 1, the cover plate F closes the upper end opening of the storage recess 13 and the suction nozzle 51 is bent and closed. Further, the protrusion 61 of the lid plate F is fitted in the hemispherical top plate 55. When the cover plate F is rotated from this state, as shown in FIG. 2, the upper end portion of the valve body 52 is elastically deformed because the protrusion 61 is displaced rearward, and the slit 56 is forcibly expanded accordingly. It is done. Therefore, when the internal pressure of the container body A rises for some reason, the pressure is reduced by expanding the slit 56. In particular, in order to expand the slit 56, even when the pressure is low, or even when the slit 56 itself is difficult to peel off for some reason, the slit 56 can be reliably expanded, and the decompression operation in the container body A can be performed. Yes. At this time, since the suction nozzle 51 is bent and closed, a phenomenon that the liquid protrudes from the suction nozzle 51 does not occur.

  When the cover plate F is further rotated to a state where the storage recess 13 is fully opened, as shown in FIG. 3, the suction nozzle 51 rises and the stored liquid can be sucked. From this state, for example, the stored liquid can be sucked from the suction nozzle 51 by holding the handle 5. The suction is performed by expanding the slit 54 of the check valve. Outside air is introduced from the internal pressure regulating valve 57 into the container body A, which becomes negative pressure as the stored liquid decreases due to suction. Further, when the suction is stopped, the tip of the suction nozzle 51 is blocked by the backflow prevention valve, so that inconvenience such as the liquid in the suction nozzle 51 returning to the container body A can be prevented.

  When the cover plate F is rotated again in the direction of closing the storage recess 13 after use, the tip of the suction nozzle 51 is pushed down by the tip edge of the cover plate F, and the state shown in FIG. At this time, since the suction nozzle 51 is compressed by a wide portion between the protruding piece 16 and the back surface of the cover plate F, the suction nozzle 51 is reliably closed.
