Description

  The present invention relates to a beverage container that has a heat-retaining structure suitable mainly for carrying, and that can be drunk directly from a drinking mouth.

  A beverage container having a heat retaining function suitable for carrying is a so-called mug bottle whose container body has a metal vacuum double structure. In this beverage container, it is also known to drink with the lips directly attached to the upper opening portion of the container body, but when the beverage to be carried is hot, the opening edge of the metal container body and the lips directly When touched, the metal container body becomes hot and difficult to drink. Therefore, it has been proposed to attach a member having a resin drinking mouth to the opening of the container body.

  Specifically, Patent Document 1 (Japanese Patent Laid-Open No. 2009-67409, FIG. 5) discloses an outer annular portion that is screwed onto the outer peripheral surface of the opening of a metal container body, and a drinking mouth that covers the upper end of the opening. A drinking mouth structure for a beverage container is disclosed that includes a ring portion integrally formed with a portion, an inner annular portion located on the inner peripheral surface of the opening, and a lid that is screwed onto the inner peripheral surface of the annular member. ing.

  In Patent Document 2 (Cross-sectional view of Design Registration No. 1386767), an annular body provided with a drinking mouth portion and an inner annular portion covering the upper edge of the opening of the metal container body, and an outer peripheral surface of the opening portion are screwed together. There is disclosed a drinking mouth structure for a beverage container that is configured with a lid that is attached and closes an opening.

FIG. 5 of Japanese Patent Laying-Open No. 2009-67409. Cross-sectional view of Design Registration No. 1386767.

  In the drink mouth structure of a beverage container provided with a metal container main body by a combination of an annular body and a lid provided with a drink mouth portion as described above, naturally the beverage structure in the container main body does not leak. (Packing structure) is adopted.

  For example, in the drinking mouth structure disclosed in Patent Document 1, packings are attached between the inner annular portion of the annular body and the container main body, and at locations facing the inner peripheral surface of the inner annular portion of the lid. ing.

  Further, in the drinking mouth structure disclosed in Patent Document 2, packing is attached between the inner annular portion of the annular body and the container main body, and at the locations facing the inner peripheral surface of the opening of the container main body in the lid. ing.

  When mounting the packing in this way, it is necessary to form the mounting portion in an appropriate recess shape so that the ring-shaped packing does not come off. Therefore, it is troublesome to remove and clean the packing, and there is a risk of liquid leakage due to forgetting to attach the removed packing.

  Therefore, the present invention proposes a beverage container having a novel drinking mouth structure that does not require packing.

  The beverage container according to the present invention is formed of an elastic material having appropriate flexibility at the opening of the container body formed of a metal vacuum double structure, and a mouthpiece covering the upper end of the opening; A drinking mouth provided with an inner annular part that can be fitted tightly to the inner peripheral surface of the opening and a hermetic receiving part in which the lower part of the inner annular part is narrowed inward is attached, and the outer peripheral surface of the opening is attached to the inner peripheral surface. A lid provided with an outer annular portion that can be screwed and a plug portion whose outer peripheral edge bites into the hermetic receiving portion at the time of mounting is crowned and mounted.

  Therefore, by attaching a resin drinking body to the opening of the container body, when drinking a beverage in the container body, the lips come into contact with the mouthpiece of the drinking body, similar to the conventional container. In addition to eliminating the inconvenience caused by adopting the metal container body for direct drinking, the mouthpiece is formed of an elastic material having an appropriate flexibility, and is closely fitted to the inner peripheral surface of the opening. The contact surface with the mouthpiece is closely attached to prevent liquid leakage from the contact surface, and the lower portion of the inner annular portion is formed in a sealed receiving portion inwardly to cover the lid. When the crown is mounted, the outer periphery of the bottom surface of the stopper portion bites into the hermetic receiving portion, and liquid leakage from between the drinking mouth and the lid (plug portion) is prevented.

  In the beverage container according to the present invention (invention 2), in the above-mentioned container, a support protrusion having a constricted shape is formed particularly in the lower part of the opening of the container main body, and a hermetic receiving part is formed on the support protrusion. Since the sealing receiving part is supported by the support protrusion against the lower pressure of the plug part, the sealing part does not descend with the lower pressure of the plug part, and the plug part is securely attached. Since it is received, liquid leakage is surely prevented.

  Furthermore, the beverage container according to the present invention (Claim 3) is formed by forming the outer peripheral edge of the lower surface of the lid portion of the lid body as a protruding edge in the container, and the protruding edge bites into the sealed receiving portion. Thus, leakage of liquid can be prevented more reliably.

  Further, the beverage container according to the present invention (Claim 4) is the above-mentioned container, and in particular, the concave portion is formed on the inner peripheral surface of the opening of the container main body, and the outer peripheral surface of the drinking body corresponds to the concave portion. It is provided with a ridge, and when the drinking body is fitted and attached to the opening of the container body, the ridge enters the concave portion and comes into close contact, so the attachment of the drinking body is surely made In addition, liquid leakage from the contact portion between the drinking body and the opening is more reliably prevented.

  The structure of the present invention is as described above. The drinking body provided with the mouthpiece portion is formed of a silicone resin having appropriate elasticity, and the stopper is provided on the lid body by narrowing the lower inner periphery to form a sealed receiving portion. Unlike the beverage container having an annular body with a conventional mouthpiece, there is no need to incorporate a packing into the stopper, etc. As a result, it is possible to provide a beverage container having a convenient mouthpiece that does not require a complicated stopper structure for incorporating the packing and does not require a troublesome packing attaching / detaching operation even during cleaning.

The disassembled perspective view of the principal part of embodiment of this invention. The whole sectional view which omitted the same portion. The same part expanded sectional view.

  Next, an embodiment of the present invention will be described. The beverage container shown in the embodiment includes a container body 1, a drinking mouth body 2 that is integrally attached to the container body 1, and a lid body 3 that performs an attaching / detaching operation.

  The container body 1 is a metal-made vacuum double structure, similar to a conventional warming portable beverage container, and is a vertically long cylindrical container having an opening 11 on the upper side, particularly on the outer peripheral surface of the opening. Is provided with a threaded portion 12 to which the lid 3 is screwed and attached, and at the lower part of the inner periphery of the opening 11, a support protrusion 13 is formed by constricting from the upper opening, and further on the inner peripheral surface of the opening Is formed with a concave strip portion 14.

  The mouthpiece 2 is formed of an elastic material having an appropriate elasticity such as silicon resin, and has an upper edge shape that covers the upper end of the opening together with the inner and outer peripheral surfaces and has no inconvenience for drinking. A mouthpiece 21, an inner annular portion 22 that can be tightly fitted to the inner peripheral surface of the opening, and a lower portion of the inner annular portion that is narrowed inward to provide a support receiving portion 13 and a corresponding sealing receiving portion 23. In addition, a protrusion 24 corresponding to the recess 14 is provided on the outer peripheral surface of the inner annular portion 22.

  The lid body 3 has an inverted container shape that is crowned from above the container body 1, and an inner thread 32 that can be screwed to the thread section 12 of the outer circumferential surface of the opening is provided on the inner circumferential surface of the outer annular portion 31. A plug portion 33 that can be inserted into the drinking mouth when the body 3 is mounted is provided. In particular, the plug portion 33 is provided with a protruding edge 34 that goes around the outer peripheral edge of the lower surface.

  Thus, when the spout body 2 is press-fitted into the opening 11 of the container body 1 and fitted and attached, the spout body 2 is formed of an elastic material having appropriate flexibility such as silicone resin. The inner annular portion 22 of the body 2 is in close contact with the inner peripheral surface of the opening portion 11, and the protrusion 24 on the outer peripheral surface is fitted into the concave portion 14, thereby preventing the mouthpiece 2 from being integrated with the container body 1. Turn into.

  Therefore, the drinking body 2 covers the upper end of the opening 11 of the container body 1 with the mouthpiece 21 suitable for drinking, so that even when the beverage is hot, it can be enjoyed without any trouble, and the drinking mouth Since the body 2 is in close contact with the inner peripheral surface of the opening 11, liquid leakage from the contact surface between the opening 11 and the drinking body 2 is prevented, and no dripping occurs during drinking. .

  The lid 3 is attached by being crowned from above the mouthpiece 2 attached to the container main body 1, and the inner thread 32 is screwed into the screw thread 12 of the container main body 1, and the stopper 33 is attached. When inserted into the inside of the mouthpiece 2, the projecting edge 34 provided on the outer peripheral edge of the bottom surface of the stopper 33 comes into contact with the hermetic receiving portion 23 squeezed inward, and the lid 3 is screwed. When proceeding, the projecting edge 34 bites into the sealed receiving portion 23.

  In particular, since the sealed receiving portion 23 is supported by the support protrusion 13 of the container body 1, the sealed receiving portion 23 is surely received against the lower pressure of the plug portion 33, and the protruding edge 34 is made of resin. 23 is surely digged into, and a water seal at the relevant location is realized, and a sufficient stopper function is exhibited.

  Therefore, the beverage container does not have a packing structure, and can surely prevent liquid leakage, and solves the problems when the packing structure is adopted.
