Description

  The present invention relates to a beverage container having a vacuum double structure.

  As is well known, a thin-metal (stainless steel) vacuum double-structured container (mug cup) is provided with an inner container part in the outer container part and a gap between the two, and is sealed with an opening edge so that a heat insulating container body is formed. The heat insulation container body is formed and commercialized by mounting appropriate stoppers and lids made of resin.

  In particular, products of the type that are directly taken from the container have a handle. For example, as disclosed in Patent Documents 1 and 2, a structure is adopted in which the handle is attached to the heat insulating container body at two upper and lower positions.

  Patent Documents 3 and 4 show a container in which a cantilevered handle is attached to a shoulder member that is attached to a shoulder portion of a heat insulating container body. The shoulder member has an appropriate thickness, and a recess is formed at a position directly below the shoulder portion of the outer container portion, and the inner peripheral surface protrusion of the shoulder member is fitted in a killed state and attached to the container body. .

  Further, as shown in Patent Document 5, the heat insulating container body is used as a soup container by attaching a heat insulating lid body to the heat insulating container body.

FIG. 2 of Japanese Patent Laid-Open No. 2008-260544. JP 2013-252220 A FIG. FIG. 6 of JP-A-7-95907. FIG. 2 of Japanese Patent Laid-Open No. 2008-239164. Unexamined-Japanese-Patent No. 2006-169042.

  In the beverage container provided with the handle disclosed in Patent Documents 1 and 2, the handle cannot be easily removed because the handle is connected to the container body in two places. Moreover, in the drink container which provided the handle by the cantilever structure to the shoulder member disclosed by patent document 3, 4, it is not the structure which attaches or detaches a shoulder member from a container body fundamentally.

  Therefore, since the beverage container provided with the handle does not remove the handle portion, even if the beverage enters the gap between the shoulder member and the container body at the time of drinking, the washing is not easy.

  Further, in a container in which a shoulder member having a cantilevered handle is attached to the container body (container of Patent Documents 3 and 4), since a load is applied to the cantilever member, a corresponding robustness is required. Since the member is required to have a suitable thickness and is fitted and attached to the concave portion on the outer peripheral surface of the outer container portion, the shoulder member protrudes from the outer peripheral surface of the container body and lacks a sense of unity with the container body in appearance. There are also design issues.

  Furthermore, this type of heat insulating container is composed of a combination of a heat insulating container body and a specific member (a lid body, a plug body, etc.), and the intended purpose of use is specified.

  Therefore, the present invention proposes a novel beverage container that has a cantilevered handle and is versatile.

  A beverage container according to claim 1 of the present invention comprises a container body and a handle attached to the container body, and the container body is formed of a metal inner / outer container portion whose opening edge is sealed. And forming a small-diameter peripheral wall on the outer peripheral surface of the opening through a step of the outer container part, and providing a screw thread on the small-diameter peripheral wall, and a handle body is constituted by a ring part and a handle part, A thread is formed on the inner circumferential surface of the ring portion to be screwed with the thread, and the upper inner circumferential surface of the thread is formed as a close contact surface with respect to the entire circumference of the small-diameter peripheral wall. It is. The beverage container according to claim 2 is formed such that the outer peripheral surface of the ring portion is flush with the container body when the ring portion of the handle body is further screwed to the peripheral wall. .

  Thus, since the handle body is screwed and attached to the container body, the attachment and detachment is easy, which is convenient for cleaning and the like, and can be a handle container for the multi-purpose container body as described later. Furthermore, in the case of a cantilevered handle, an unequal load is applied to the ring part, but the upper inner peripheral surface of the link part is in close contact with the small peripheral wall of the container body, so that deformation of the ring part is suppressed. It is difficult for screw disengagement to occur. However, the container body has a wide mouth for facilitating the dispensing of the contents, and in order to increase the capacity as much as possible, when the distance between the inner and outer container parts is small, the step width of the small diameter peripheral wall must be reduced. I must. Even if a ring portion (a flush configuration) having a thickness that matches this step is employed, even if the step width is small, the ring portion can be accommodated by the close fitting structure of the ring portion.

In addition, the beverage container according to claim 3 of the present invention is provided with a small diameter step on the upper outer peripheral surface of the ring portion, and is mounted on the opening of the container body and is positioned on the small diameter step when mounted. A drinking mouth provided with a peripheral surface portion that is flush with the outer peripheral surface of the portion is attached.
That is, various structures can be adopted as the drinking body, but when it is mounted on the container body (press-fit mounted on the opening), by providing a peripheral surface portion that presses the small diameter step of the ring portion from above, This further prevents distortion of the ring part based on the load applied to the ring part during use, and by making it flush, continuity in appearance is exhibited and brings about a sense of unity as an article.

  Moreover, the beverage container according to claim 4 of the present invention is particularly attachable to the opening of the container body, and is attached with a can holding body in which a tongue piece for holding a beverage can is suspended from the upper end. Thus, when the can holding body is mounted on the container body instead of the handle body or the drinking body (screwed mounting on the small peripheral wall or fitted on the opening), it can be used as a heat retaining holder for the beverage can. That is, when the lower portion of the beverage can is stored in the container so as to spread the tongue, the tongue becomes a resistance and can be prevented from detaching from the container, and can be drunk in the stored state.

  The beverage container according to claim 4 of the present invention can be attached to the opening of the container body in particular, and is attached with a lid plug that seals the opening of the container body when attached. If a sealed lid is attached to the container body instead of the drinking body (screwed on the small diameter peripheral wall or fitted on the opening), it can be used as a heat retaining soup cup.

  The structure of the present invention is as described above, and adopts a structure that prevents the occurrence of distortion at the time of screwing and mounting due to a load applied to the handle body having a cantilever structure, thereby realizing screwing and mounting of the handle body. The handle body having a holding structure can be freely attached and detached, and is convenient for cleaning and the like.
