TECHNICAL FIELD The present invention relates to an exterior structure of a metal heat-retaining container such as a portable beverage container or a food jar.

Portable beverage containers are provided with non-slip means (grip) on the outer peripheral surface of the container body (container) as disclosed in Patent Document 1 below, or as disclosed in Patent Document 2 below, in order to make it easier to hold. It is known to provide a handle so that it can be held in place.

These grips and handles are integral with the container and are basically not detachable.

In addition, when the grip is composed of a member separate from the container, the shape of the outer peripheral surface of the grip is the same in the circumferential direction, and does not have directionality in relation to adjacent members such as the container in the attached state. In addition, "the same" in the same outer peripheral shape means that the basic shape is the same. For example, if the grip surface has unevenness like a polka dot pattern, the outer peripheral shape is said to be the same in the circumferential direction. It will be.

JP-A-11-253330 Japanese Patent No. 5498601

Since the grip and the like are integral with the container as described above, they cannot be removed even if they are not needed.

In addition, as described above, the shape of the grip does not have directionality in the circumferential direction, and it has not been easy to obtain an easy-to-hold grip suitable for a metal heat-retaining container or a well-designed grip.

SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to provide a grip or the like that can be removed when not needed and that is excellent in functionality and design.

Means for this purpose comprise a container having an opening at its upper end, a stopper screwed onto the upper end of the container, and a cylindrical member mounted on the outer peripheral surface of the container. Furthermore, a receiving surface having a smaller diameter is formed in the upper portion thereof, while an abutting portion is formed on the inner peripheral surface of the upper end portion of the cylindrical member so as to contact the receiving surface from above. A spiral ridge having a receiving end surface rearward in the direction of rotation associated with screwing of the plug is formed on the upper end surface, and a spiral recess corresponding to the helical ridge is formed on the lower end surface of the plug. At the rear end of the spiral concave portion in the rotational direction, an abutment end surface is formed that abuts against the receiving end surface. It is a cylindrical member mounting structure of a metal heat insulating container set to be pressed against.

In this configuration, when the container is covered with the cylindrical member and then the stopper is screwed onto the container, the stopper rotates and descends as the screw is engaged. In accordance with this movement, the abutting end face of the spiral recess on the lower end face of the plug moves in the rotational direction, and hits the receiving end face of the spiral ridge formed on the upper end face of the cylindrical member, rotating the cylindrical member. At this time, the plug and the cylindrical member are in a fixed positional relation in the circumferential direction, and when the plug is further rotated while maintaining this positional relation, the mounting of the plug to the container is completed. Sandwiched between the container. The upper end surface of the cylindrical member is fitted to the lower end surface of the stopper, the abutting portion of the cylindrical member is pressed against the receiving surface of the container, and the cylindrical member does not rotate alone in the rotational direction or in the opposite direction. Become. The stopper is attached to the container without the cylindrical member.

According to this invention, the cylindrical member is fixed in a fixed positional relationship with the plug by attaching the plug, but the plug can be attached to the container without the cylindrical member. Therefore, the cylindrical member can be attached only when necessary. In other words, when the cylindrical member is unnecessary, it can be removed and the metal heat insulating container can be used.

In addition, since the cylindrical member is fixed in a fixed positional relationship with the stopper even though it is detachable, it is possible to obtain a grip or the like excellent in functionality and design.

The shape of the container 12 is a cylinder with a bottom, and the outer peripheral surface has a straight shape with no dents in the vertical direction. A receiving surface 23 is formed at a position immediately below the threaded portion 22 to reduce the diameter of the threaded portion 22 . The receiving surface 23 has the same vertical cross-sectional shape in the entire circumferential direction, and the vertical cross-sectional shape is an arc shape close to a quarter arc.

The stopper 13 is attached to the container 12 by screwing, and has a structure for taking out the beverage inside the container 12 in the attached state. As a structure for that purpose, there are a spout for tilting and pouring out, a spout for drinking directly with the mouth, a straw for sucking and drinking, etc., but the illustrated example shows the stopper 13 equipped with the straw 31. .

As shown in FIG. 3, which is a cross-sectional view, the plug 13 is composed of a main body member 32 that is attached to the container 12 and an upper end member 33 that is fitted onto the main body member 32 in a non-fitting state. ing.

The main body member 32 has a fitting cylinder portion 34 fitted onto the upper end of the container 12 , and a stopper threaded portion 35 screwed onto the threaded portion 22 of the container 12 on the inner peripheral surface of the fitting cylinder portion 34 . have. A closing portion 36 that closes the opening 21 of the container 12 is integrally formed on the fitting cylinder portion 34 .

The upper end member 33 includes a handle 37 for hanging, a rotating operation tool 38 for taking in and out the straw 31 and for opening and closing the liquid passage 31a in the straw 31, and tilted when the liquid passage 31a is closed. It has a receiving recess 39 for receiving the mouth of the straw 31 . The straw 31 is composed of an upper member 31 b and a lower member 31 c , and the upper member 31 b is held by the plug 13 . The lower member 31c is detachable from the upper member 31b.

The handle 37 has a closed loop shape extending from both left and right sides of the upper end member 33 to form an inverted U shape, and extends obliquely upward and rearward. The rotating operation tool 38 is pivotally attached to the front of the upper end member 33 opposite to the direction in which the handle 37 extends, and is rotatable from the upright posture to the fallen posture in the direction to move the upper member 31b of the straw 31. It is inserted and held inside. A lever 38b for rotating operation is formed on the side of the holding hole 38a that holds the upper member 31b. When the lever 38b is raised, the upper member 31b of the straw 31 falls backward to open the internal liquid passage 31a. is compressed and deformed to be closed.

A spiral concave portion 41 is formed on the lower surface of the plug 13, that is, the lower surface of the fitting tube portion 34, as shown in FIG. The spiral recessed portion 41 is a recessed portion that has a height difference so as to draw a spiral in a part of the lower end surface of the annular fitting cylinder portion 34 in the circumferential direction. The spiral recessed portion 41 is formed with an appropriate length, and in this example, it is formed at a portion of three-fourths of the circumferential length. A wall portion 42 is formed on the thick outer portion of the fitting cylinder portion 34 and on the inner peripheral side.

The spiral recessed portion 41 also has a vertical butting end face 43 at the rear end in the rotational direction D in screwing with the container 12 .

The grip member 15 a has a cylindrical shape and is sized to fit over the upper portion of the container 12 . The grip member 15a has a non-slip function, that is, has a non-slip surface, but since it is a portion to be gripped, it is necessary to have rigidity in the mounted state. The grip member 15a can be made of only a non-slip material such as rubber.

For this reason, the grip member 15a is composed of an inner-layer hard member 51 and an outer-layer anti-slip member 52, as shown in the sectional view of FIG. A synthetic resin such as polypropylene can be used for the hard member 51, and a rubber material such as silicone rubber can be used for the anti-slip member 52. As shown in FIG. The anti-slip member 52 may be formed in a necessary portion, and is provided in a portion of the grip member 15a excluding the upper end portion and the lower end edge.

A window portion 51a is formed in the hard member 51 so as to partially penetrate inside and outside, and a convex portion 52a is formed on the inner surface of the anti-slip member 52 so as to fit into the window portion 51a. The convex portion 52 a is preferably formed slightly thicker than the window portion 51 a so as to protrude inward from the inner peripheral surface of the hard member 51 .

The grip member 15a has an outer circumferential surface shape that is partially different in the circumferential direction, and has directionality in relation to the plug body 13 in the attached state. In other words, the grip member 15a, like the plug 13, has an orientation to be oriented in use.

Here, "the outer peripheral surface shape is partially different in the circumferential direction" means that the basic shape of the outer peripheral surface shape is different. Say.

The illustrated grip member 15a has a horizontal opening 53 at its upper end and an oblique opening 54 at its lower end. The opening 54 at the lower end is lower on the front side than on the rear side. Further, the anti-slip member 52 has a ridgeline portion 55 that protrudes outward and continues in the circumferential direction, and the ridgeline portion 55 has a height difference in the vertical direction in the circumferential direction. Specifically, the portion 55a corresponding to the front side of the plug 13 in the ridgeline portion 55 is formed at a lower position in the vertical direction, and the portion 55b corresponding to the rear side of the plug 13 is formed at an upper position. , and the portion corresponding to the side surface is slanted upward toward the rear. In addition, the height of the ridgeline portion 55 is formed higher on the rear side than on the front side.

The grip member 15a, which is directional when attached, has the receiving surface 23 formed on the upper portion of the container 12 as described above. The inner peripheral surface of the upper end portion is formed to have an arcuate longitudinal section. The inner peripheral surface having an arcuate vertical cross section is a contact portion 56 that abuts against the receiving surface 23 from above. As shown in FIG. 3, the contact portion 56 is shaped to contact the receiving surface 23 as a whole. A state is created in which relative movement to is blocked.

As shown in the perspective view of FIG. 2, the upper end surface of the grip member 15a is formed with a spiral ridge 58 having a receiving end surface 57 behind in the rotational direction D associated with the screwing of the plug 13. As shown in FIG. The spiral ridge 58 is formed at an intermediate position in the thickness direction of the grip member 15a on the annular flat portion 59 on the upper end face, and is formed in a portion of three-fourths of the circumferential length.

The spiral recess 41 on the lower end surface of the plug body 13 described above has a shape corresponding to the spiral ridge 58 , and the abutment end surface 43 of the spiral recess 41 is a portion that contacts the receiving end surface 57 of the spiral ridge 58 . The forming positions of the abutment end face 43 and the receiving end face 57 are set so that the plug body 13 and the grip member 15a face in the same direction when they are in contact with each other.

Further, the screwing amount of the stopper 13 to the container 12 is set so that the grip member 15a is pressed against the receiving surface 23 when the screwing to the container 12 is completed.

In the portable beverage container 11 configured as described above, the grip member 15a is detachable and attached when necessary.

When attaching, first, the upper end of the container 12 from which the stopper 13 is removed is covered with the grip member 15a. At this time, the contact portion 56 of the grip member 15a abuts on the receiving surface 23 of the container 12 and is positioned in the vertical direction, and is rotatable in the circumferential direction.

Next, the plug 13 is screwed onto the threaded portion 22 of the container 12 . Then, the plug body 13 rotates and descends as it is screwed. In accordance with this operation, the abutment end face 43 of the spiral recess 41 on the lower end face of the plug 13 moves in the direction of rotation as indicated by the phantom lines and arrows in FIG. It hits the receiving end surface 57 of the spiral ridge 58 and hooks the grip member 15a. When the abutment end surface 43 is in contact with the receiving end surface 57, the plug body 13 and the grip member 15a have a fixed positional relationship in the circumferential direction.

When the attachment of the plug 13 to the container 12 is completed by further rotation of the plug 13, the grip member 15a is sandwiched between the plug 13 and the grip member 15a. That is, the helical ridge 58 of the grip member 15a fits into the helical recess 41 of the plug 13, the abutting portion 56 of the grip member 15a is pressed against the receiving surface 23 of the container 12, and the grip member 15a alone rotates in the direction of rotation. It will be in a state where it does not rotate in either direction.

In this manner, the grip member 15a is automatically fixed in a fixed positional relationship with the plug 13 when the plug 13 is attached.

When carrying the portable beverage container 11, the user can hold the handle 37 and hold the grip member 15a. Since the grip member 15a has anti-slip properties, stable holding is possible. The grip member 15a is present at the upper end of the container 12 near the straw 31 and has a ridge line portion 55. As shown in FIG. Since the ridgeline part 55 is higher on the rear side than on the front side, a good fitting feeling can be obtained when held by the hand, and the portable beverage container 11 can be easily tilted forward, and has high functionality.

Moreover, unlike the conventional grip, the grip member 15a has a novel design.

In this way, unlike conventional grips, the grip member 15a can be designed with an emphasis on function and design.

When the grip member 15a is not required, the plug 13 is removed, the grip member 15a is pulled out, and the plug 13 is attached. FIG. 7 shows a perspective view of the portable beverage container 11 with the grip member 15a removed. Thus, even without the grip member 15a, the stopper body 13 can be used as a portable beverage container 11 without any change in the attached state.

The above configuration is one mode for carrying out the present invention, and the present invention is not limited to the configuration described above, and other configurations can be employed.

For example, the receiving surface 23 can be formed separately from the threaded portion 22 .

The cylindrical member 15 may be directional in relation to the plug 13 .

The receiving surface 23 of the container 12 may be an inclined surface.

The helical recess 41 and helical ridge 58 may be shorter or longer than three quarters of the circumferential length.

Also, the cylindrical member 15 may be something other than the grip member 15a, one example of which is shown in FIG.

The cylindrical member 15 in FIG. 8(a) is a handle member 15b having a handle 61 on its side surface. The handle 61 has an inverted L shape, and the length of the handle 61 is formed to match the height of the handle member 15b.

The cylindrical member 15 in FIG. 8(b) is also a handle member 15b, and has a handle 62 on its side, and this handle 62 is U-shaped. That is, the portion 63 of the handle member 15b in the circumferential direction, which is provided with the handle 62, is elongated in the vertical direction to provide the handle 62 with a desired length.

The cylindrical member 15 in FIG. 8(c) is a hanging string attachment member 15c to which the hanging string 64 can be attached, and an engagement projection 65 is formed on the side surface to allow the hanging string 64 to be attached and detached. Note that the hanging string 64 may not be detachable.

A cylindrical member 15 in FIG. 8(d) is a cover member 15d for cushioning and decoration. That is, the cover member 15d is formed in a tubular shape to cover the entire portion of the container 12 below the receiving surface 23, and has the desired functions of cushioning and decoration. The cover member 15d can prevent dents caused by collisions and peeling of the paint film, and can provide a desired appearance to make the container beautiful and distinguishable from others' containers.
