Description

  The present invention relates to a beverage server comprising a liquid storage container having a resin handle.

  In order to make it easy to have a liquid storage container for storing drinking water or the like, a handle is provided on the container. Such a handle cannot be integrally formed with the liquid storage container. However, for example, in the case of a glass container, integrally forming a container with a handle becomes extremely complicated in production. For example, in the case of a resin container, integral molding of the handle becomes easy, but the molding die becomes complicated, and it becomes difficult to reduce the manufacturing cost.

  Therefore, a handle that has been formed separately from the liquid storage container and can be attached to a predetermined region regardless of the material of the container has been proposed (for example, see Patent Documents 1 and 2). In this case, the handle is formed integrally with a band-like band that wraps around the outer periphery of a collar portion such as a mouth-and-neck portion of the container whose diameter is reduced. The band-shaped band is made of a synthetic resin having flexibility, and in the state where the collar part of the container is wound, the two handle halves connected to both ends of the band are combined and integrated. A handle is formed.

  By the way, in a beverage server comprising a liquid storage container provided with a handle formed integrally with a resin band as described above, in manufacturing the liquid storage container, there is an occurrence of an outer peripheral tolerance in a collar part around which the band is wound. Unavoidable. However, in the handle integrally formed with the attachment body (band) made of a flexible synthetic resin shown in Patent Document 1, the outer periphery of the handle is small due to the tolerance of the neck portion of the container mouth (the heel portion). , The winding around the heel of the band becomes loose. The band engages with the container and does not fall off from the container, but moves with the handle in the circumferential direction of the collar in the container. With this handle, there is no place that can absorb the tolerance of the outer periphery of the container, and it is difficult to attach a handle that is stably fixed in all products of the beverage server. In particular, it is impossible to cope with a container in which the outer periphery tolerance of the heel portion is increased.

  Therefore, Patent Document 2 proposes a structure in which a corrugated region is provided in a band wound around the flange portion of the container, and the outer periphery tolerance of the container can be absorbed. However, in a beverage server equipped with this handle, for example, if the handle is firmly fixed and attached to a glass liquid storage container, there is a risk that it will be damaged due to excessive stress locally in the corrugated region of the band. . Therefore, the handle cannot be firmly fixed to the container. In the case of this structure, unless a stopper is further provided in a predetermined region of the band, there is a problem that the handle integrally formed with the band moves in the outer peripheral direction of the collar portion of the container.

  Embodiments of the present invention will be described below with reference to FIGS. Here, parts that are the same or similar to each other are denoted by common reference numerals, and a duplicate description is partially omitted.

(First embodiment)
FIGS. 1 to 7 illustrate this embodiment. As shown in FIGS. 1 and 2, the beverage server 10 includes a handle 12 and a resin band 13 for a liquid storage container 11 made of glass, for example. It is prepared for. The band 13 is fastened by a connecting portion 20.

  Here, the liquid storage container 11 has a bottomed cylindrical shape opened upward, has a circular cross section, and has an opening 11a and a spout 11b in the upper part thereof. In the liquid storage container 11, for example, the intermediate height is reduced in diameter to form a flange 11 c, and the outer peripheral surfaces 11 d and 11 e are curved and swollen on the outer peripheral surfaces on both sides of the flange. The cross section of the buttocks is also circular. However, the cross section includes an ellipse, a partially cut circle, and the like. In addition to the glass container, the liquid storage container 11 may be a resin container, a metal container, ceramics, or the like. In such a liquid storage container 11, a visible mark for alignment with the handle 12 to be attached may be formed.

  The handle 12 is annular and can be gripped by inserting a finger, and has a hollow structure. The handle 12 includes a first handle half 121 and a second handle half 122 that are cut into two in the axial direction of the liquid storage container 11, that is, in the vertical direction. The first handle half body 121 and the second handle half body 122 have a pair of half-shaped annular shapes, and are combined and integrated into the handle 12 as will be described in detail later. Here, as shown in FIG. 3, the first handle half 121 is integrally formed with one end of the resin band 13, and the second handle half 122 is formed separately from the band 13. Here, the first handle half body 121 is made of the same resin as that of the band 13, but an appropriate material such as resin, metal, or inorganic insulator is used for the second handle half body 122. The resin may be the same as or different from that of the first handle half 121.

The first handle half body 121 has an annular semi-hollow half body structure, an elongated flange-shaped pressing portion 121a that presses the second handle half body 122 against the outer peripheral surface of the liquid storage container 11, and It is defined by a first coupling part 121b that is formed in a semi-hollow opening edge and is coupled to the second handle half 122. The pressing part 121a extends along the outer walls 11d and 11e of the container on both sides in the axial direction of the liquid storage container with respect to the connecting part 20. A first reinforcing rib 121d for connecting to the other end of the band 13 and the second handle half is formed in a predetermined region on the inner wall side of the first handle half. With the first reinforcing rib 121d, the mechanical strength of the first screw hole 121c for inserting the screw 14 and locking the screw head 14a and the first handle half body 121 can be ensured.
The first handle half body 121 may be provided with a liquid discharge port 121e below the first handle half body 121.

  Similarly, the second handle half 122 is an annular semi-hollow half. And it has the fixing | fixed part 122a overlapped so that it may become a container side with respect to the press part 121a of the 1st handle half body 121, and is narrowly pressed by the outer peripheral surface of the liquid storage container 11. FIG. The fixing portion has a long and narrow flange-like plate shape and is wider than the pressing portion 121a in order to increase the contact surface with the outer wall of the container. Similarly to the pressing portion 121a, the fixing portion 122a extends along the bulges of the container outer walls 11d and 11e on the upper and lower sides of the connecting portion 20, that is, on both sides in the container axial direction. Further, a second coupling portion 122b coupled to the first coupling portion 121b of the first handle half body 121 is provided at the semi-hollow opening edge. And the fitting part which consists of the fitting wall 122c, the fitting protrusion 122d, etc. is formed in the inner wall of the 2nd handle half body 122 so that the other end of the band 13 may fit. Further, the second handle half 122 is reinforced by a required number of second reinforcing ribs 122e provided on the inner wall thereof. Furthermore, a screw receiver 122f serving as a receiving port at the tip of a screw connecting the other end 13f of the band 13 to the first handle half body 121 may be provided. Further, a liquid drain port 122g may be provided below the second handle half 122.

  The first handle half body 121 and the second handle half body 122 may have a structure in which the handle 12 is cut into two in the vertical direction, or are cut into different sizes. It may be.

  The band 13 is made of, for example, flexible synthetic resin such as polypropylene, and has a plurality of band ribs 13 a wound around the outer peripheral surface of the flange portion 11 c of the liquid storage container 11 and formed along the edge thereof. One end of the band 13 is integrally connected to the first handle half 121, and the other end 13f is a coupling end, that is, a tongue-like narrow portion 13b that is bent and contracted. A second screw hole 13c is formed in the narrow portion 13b, and a fitting groove 13d is formed in the thickness direction of the band 13 at the tip. Further, an insulator nut 15 (FIG. 4) having a screw hole for screw screwing on the back side of the band 13 in the region of the second screw hole 13c is fixed by, for example, press fitting.

  In such a band 13, a convex portion 13e for positioning the liquid storage container 11 and the handle may be formed at a predetermined position inside the band, for example, at a position corresponding to the lower part of the container inlet 11b. Such a convex portion 13e is simply formed by effectively using the resin inlet of the mold provided to allow the resin to flow in the integrally molded mold of the first handle half body 121 and the band 13. The

  In the beverage server 10, the band 13 is wound around the outer peripheral surface of the flange portion 11 c of the liquid storage container 11, and the other end is fastened to the first handle half body 121 by the connecting portion. Here, although the band 13 provided along the edge of the band 13 comes into contact with the outer peripheral surface of the flange portion 11c, the entire band 13 may come into contact with the outer peripheral surface of the flange portion 11c.

  In the connection between the other end 13f of the band 13 wound around the outer peripheral surface of the flange portion 11c of the liquid storage container 11 and the first handle half body 121, as shown in FIG. The nut 15 having a screw hole fixed to the other end of the band 13 surrounding the outer periphery of the flange portion 11c is screwed. Here, as described above, the nut 15 is press-fitted into the narrow portion 13 b at the other end of the band 13, for example. The screw 14 passes through the first screw hole 121 c provided in the first handle half 121 and the second screw hole 13 c provided in the other end of the band 13 and is screwed into the nut 15. Here, in a state where the second handle half 122 is coupled and integrated with the first handle half 121, the tip of the screw 14 screwed into the nut 15 is connected to the screw receiver 122f of the second handle half 122. You may come in. Further, the second screw hole itself may be formed as a screw hole.

  It is preferable that the screws (including bolts) 14 and the nuts 15 serving as the connecting portion 20 are made of an insulator. This is because the beverage server 10 can be safely applied to microwave heating by, for example, a microwave oven because it is not a metal part. There are various other connecting portions. For example, a screw hole is provided in the other end 13f of the band 13, and the screw 14 is screwed into the screw hole. In this case, the other end of the band 13 is preferably thicker than other regions.

  In such tightening by the connecting portion, for example, depending on the tightening degree between the screw 14 and the nut 15, the band 13 wound around the flange portion 11 c of the liquid storage container 11 is tightened and the second handle half body 122 is fixed. The pressure contact force to the container outer wall in the container axial direction of the portion 122a can be adjusted. Here, when tightening is strengthened, the tightening strength of the band 13 increases. Moreover, since the pressing force from the pressing portion 121a of the first handle half body 121 increases, the fixing portion 122a increases the strength of being compressed on the outer peripheral surface of the liquid storage container 11, so that the fixing portion 122a is fixed more strongly. become.

  Thus, since the handle 12 and the band 13 can be firmly fixed and attached to the liquid storage container 11, even if the volume and weight of the liquid storage container 11 increase, the beverage server can handle such as carrying it. Is extremely easy and convenient.

  In the coupling of the two handle halves, for example, as shown in FIG. 5, the engagement groove 121 f provided in the first coupling part 121 b of the first handle half 121 and the second handle half 122 are second. The engaging protrusion 122h provided on the coupling portion 122b is engaged. In the two coupling portions, the second handle half body 122 has large spring elasticity, and comes into strong contact by being pressed from the inside of the first handle half body 121. Here, the first handle half 121 and the second handle half 122 have a U-shaped cross section, but may have a shape other than the U-shape. On the contrary, the first projection half 121 has a structure in which an engagement protrusion is provided in the first coupling portion 121b and an engagement groove is provided in the second coupling portion 122b of the second handle half 122. May be.

  In this way, the handle 12 becomes a hollow structure in which the two handle halves are joined together, so that even when the volume and weight of the liquid storage container 11 increase, handling, such as carrying, is easy in the beverage server. become.

  In the band 13 wound around the outer peripheral surface of the flange portion 11 c of the liquid storage container 11, the narrow width portion 13 b at the other end 13 f is fitted into the second handle half 122. In this fitting, as shown in FIG. 6, the narrow portion 13 b at the other end of the band 13 is fitted into the fitting wall 122 c of the second handle half 122. Then, the fitting protrusion 122d of the second handle half 122 is fitted into the fitting groove 13d.

  In the tightening of the other end of the band 13 and the first handle half body 121 described above, if the tightening strength by the connecting portion increases, the tensile stress of the band 13 increases. Due to this tensile stress, the screw 14 is displaced in the direction of the liquid storage container 11 together with the other end of the band 13 through the second screw hole 13c. However, this displacement is prevented by the fitting groove 13d fitted into the fitting protrusion 122d of the second handle half 122. On the contrary, the second handle half 122 receives a pressing force from the other end of the band 13 to the outer peripheral surface of the liquid storage container 11 at the fitting portion. Moreover, the arrangement | positioning of the horizontal direction of the band 13 is correct | amended when the narrow part 13b used as the other end of the band 13 engages with the fitting wall 122c.

  Next, the attachment of the handle 12 and the band 13 to the liquid storage container 11 will be described with reference to FIG. In this figure, the other end of the band 13 and a part of the second handle half 122 that becomes the handle 12 are shown. However, the first handle half is joined and integrated with the second handle half 122. 1 to 5 will be referred to for the handle half 121 of the handle.

  The band 13 having the first handle half body 121 at one end is wound so as to surround the flange portion 11 c of the liquid storage container 11. At that time, the mounting of the handle 12 in the liquid storage container 11 can be positioned by the visually recognizable mark provided on the liquid storage container 11 described above. Alternatively, the positioning protrusions 13e formed on the band 13 as described above may be used for positioning the handle 12.

  Then, the other end of the band 13 is brought to a position where it can be screwed to the first handle half body 121 as shown in FIG. At the same time, as shown in FIG. 7, the second handle half body 122 is mounted and positioned so that the narrow width portion 13b, which is the other end of the band 13, is bent into the fitting wall 122c. In this positioning state, the screw 14 is inserted from the first screw hole 121c of the first handle half 121 into the screwing shaft M along the second screw hole 13c of the narrow width portion 13b of the band 13, and the narrow width portion 13b. Are screwed onto a nut 15 fixed on the back side. Further, the first handle half body 121 and the second handle half body 122 are coupled to each other through the first coupling portion 121b and the second coupling portion 122b.

  Then, the other end of the band 13 is fastened to the first handle half 121 with an appropriate strength. In this tightening, the second handle half 122 to which the other end of the band 13 is fitted is pressed against the outer peripheral surface of the liquid storage container 11. That is, the fixing part 122a of the second handle half 122 is sandwiched between the pressing part 121a of the first handle half 121 and the container outer walls 11d and 11e and is pressed by the pressing part 121a. The first handle half body 121 and the second handle half body 122 in which the pair of the fixing portion 122a and the pressing portion 121a are coupled to each other are integrated into the handle 12, and are firmly fixed on the outer peripheral surface of the liquid storage container 11. The

  In the beverage server 10 of the present embodiment, a resin band 13 is wound around the outer peripheral surface of the collar portion 11 c of the liquid storage container 11. Then, the first handle half body 121 integrally formed at one end of the band 13 is combined with the second handle half body 122 formed separately from the band 13 to be integrated into the handle 12. Here, the other end of the band 13 wound around the outer periphery of the flange portion 11c is fastened to the first handle half body 121 by the connecting portion. By this tightening, the second handle half body 122 is pressed and fixed to the outer peripheral surface of the liquid storage container 11 via the first handle half body 121 on both sides of the connecting portion 20 in the middle.

  For this reason, in the manufacture of the liquid storage container 11, even if the outer peripheral tolerance of the flange portion 11 c increases, the handle 12 is firmly attached to the liquid storage container 11 regardless of the tolerance by adjusting the tightening degree by the connecting portion. It can be fixed and installed. Further, the fixing strength can be appropriately set by adjusting the tightening degree by the connecting portion.

  Even if the handle 12 and the band 13 are firmly attached to the liquid storage container 11, the tensile stress applied to the band 13 due to the grip 12 and the band 13 is uniformly applied to the band 13. For this reason, the local stress load in the band region which has occurred in the prior art is eliminated. And the damage of the band which originates in this local excessive stress is prevented.

  Further, the handle 12 and the band 13 can be firmly fixed and attached to the liquid storage container 11. Alternatively, since the handle 12 becomes a hollow structure in which two handle halves are joined together, even if the volume and weight of the liquid storage container 11 increase, handling of the carrying server etc. is extremely easy in the beverage server. It becomes convenient.
