  The present invention relates to a beverage server comprising a glass container with a handle made of a synthetic resin, and is particularly configured to use a handle without using metal parts so as to be applicable to microwave heating, and is easy to assemble and highly safe. It relates to a beverage server.

FIG. 6 shows a conventional example in which a beverage server made of a glass container having a synthetic resin handle is used without using metal parts in the handle. This beverage server is provided with a collar 25 at the bottom of the opening 24 of the glass container 21, the outer periphery of the collar 25 is surrounded by a synthetic resin band 22, and a handle 23 is provided integrally with the band 22. The band 22 is obtained by polymerizing both ends of each other and bonding with a fastener 31 made of a synthetic resin (see Patent Document 1).
JP-A-8-70973

  In the conventional beverage server, both ends of the band 22 are polymerized to each other, and both are joined by a synthetic resin fastener 31. Therefore, if the fastener 31 falls off for some reason, the band 22 opens. There is a possibility that the glass container 21 falls. Further, in the assembly work of the product, there is a problem that the process of press-fitting the fastener 31 takes time and confirmation of the connection is not easy. Accordingly, the present invention is a beverage server comprising a glass container with a low microwave loss and a synthetic resin handle, the handle being firmly fixed to the glass container, and the glass container being detached from the handle during use. It is an object of the present invention to provide a device that is easy to assemble with few parts.

  In the present invention, in order to solve the above-mentioned problems, a glass container 1 having a circular cross section having an opening 4 in the upper part and a flange part 5 in the lower part of the opening 4 and the outer periphery of the flange part 5 of the glass container 1 are provided. A beverage server is configured by including a surrounding synthetic resin band 2 and an annular grip 3 provided integrally with the band 2. The handle 3 is formed by joining a pair of annular halves 7 and 8 integrally formed at both ends of the band 2 and can be gripped by inserting fingers. An engagement groove 9 is formed in one half 7 constituting the handle 3. The engagement groove 9 can be an annular groove that is continuous over the entire area of the half part 7. The engagement groove 9 opens to the joint surface 7a side. A pair of outer peripheral walls 10 and 11 are formed on both sides of the engagement groove 9. The outer peripheral walls 10 and 11 can also be formed continuously. The other half 8 constituting the handle 3 is provided with an engagement protrusion 12 protruding from the joint surface 8a so that it can be inserted into the engagement groove 9 of the one half 7. The engaging protrusion 12 can also be provided continuously over the entire area of the half 8. At least one of the outer peripheral walls 10 and 11 of one half 7 and the engagement protrusion 12 of the other half 8 are snapped to each other when the engagement protrusion 12 is inserted into the engagement groove 9. The engaging portions 11a and 12a to be engaged are formed.

  In the beverage server of the present invention, the handle 3 is firmly fixed to the glass container 1 by snap-engaging the pair of halves 7 and 8 provided integrally at both ends of the band 2. There are few and assembly work is easy. During use, the fingers are inserted into the annular handle 3 and grasped, so that the glass container 1 should be detached from the handle 3 even if the halves 7 and 8 of the handle 3 are disengaged. There is no safety.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the beverage server of the present invention with a part cut away, FIG. 2 is a sectional view of the beverage server of the present invention, FIG. 3 is a sectional view taken along line III-III in FIG. FIG. 5 is a front view of the state before the band and the handle are attached.

  The beverage server includes a glass container 1, a synthetic resin band 2, and a handle 3 integrated with the band 2.

  The glass container 1 is substantially frustoconical and has an opening 4 at the top. The upper part of the glass container 1 extends upward through the flange 5. At the edge of the opening 4, a groove-shaped spout 6 bent in a substantially V shape is formed.

  The band 2 is formed of an elastic synthetic resin having heat resistance and low microwave loss, such as polypropylene, and surrounds the outer periphery of the flange portion 5 of the glass container 1. The handle 3 is formed integrally with the band 2 and has an annular shape in which fingers can be inserted and gripped.

  The handle 3 is formed by connecting a pair of annular halves 7 and 8 integrally formed at both ends of the band 2 to each other. The halves 7 and 8 are connected to each other in a state in which the flange 5 of the container 1 is surrounded by the band.

  One half of the annular half 7 constituting the handle 3 includes an engagement groove 9 continuous over the entire area of the ring. The engagement groove 9 is formed between the pair of annular outer peripheral walls 10 and 11 and opens to the joint surface 7a side. On the outer peripheral wall 11, an engagement protrusion 11 a that protrudes inside the engagement groove 9 is formed.

  The other half half 8 of the ring constituting the handle 3 is provided with an engaging protrusion 12 that is continuous over the entire area of the ring. The engagement protrusion 12 protrudes from the joint surface 8a toward the one half 7 so that it can be inserted into the engagement groove 9 of the one half 7. The engagement protrusion 12 has a cross-sectional shape similar to the cross-sectional shape of the engagement groove 9, and has a groove 12 a that is elastically fitted to the engagement protrusion 11 a when inserted into the engagement groove 9. A plurality of engaging protrusions 12 may be formed discontinuously over the entire region of the half portion 8 or a part thereof.

  A rectangular half-wave corrugated portion 13 for imparting elasticity in the extending direction to the band 2 is formed in a substantially central portion of the band 2 so as to protrude radially outward. A pair of reinforcing ribs 14 are formed on both inner edges of the corrugated portion 13. The reinforcing rib 14 is semi-cylindrical, and the thickness of the intermediate portion of the corrugated portion 13 is increased in the circumferential direction and the radial direction of the band to adjust the elasticity in the circumferential direction of the band, and the plastic deformation is extended. It protrudes inward in the radial direction, and the tip can contact the outer periphery of the flange 5 of the container 1. A pair of fastening ribs 15 are formed in the vicinity of both ends of the band 2. The fastening rib 15 protrudes inward in the radial direction, and the tip abuts on the outer periphery of the flange portion 5 of the container 1. A pair of detent protrusions 16 along both sides of the lower surface of the spout 6 of the container 1 are formed on both upper sides in the circumferential direction of the corrugated portion 13 of the band 2.

  The beverage server of this embodiment is completed simply by winding the band 2 around the collar part 5 of the glass container 1 and strongly butting the half halves 7 and 8 of the handle. That is, when the halves 7 and 8 are strongly abutted with each other, the engaging protrusion 12 is pushed inward while elastically expanding the engaging groove 9, and the groove 12a is engaged with the engaging protrusion 11a. Fits elastically. Since the engagement protrusion 12 and the engagement groove 9 engage with each other over the entire ring of the halves 7 and 8, the coupling between the halves 7 and 8 is strong. By confirming the mutual joining of the joining surfaces 7a and 8a, the coupling between the half portions 7 and 8 can be easily confirmed.

  Since it is composed of only a microwave low-loss glass container 1, a synthetic resin band 2 and a handle 3, it is suitable for heating in a microwave oven. When the band 2 is wound around the glass container 1, the end surfaces of the contact piece 14 and the rib 15 are in contact with the outer peripheral surface of the flange portion 5, and the corrugated portion 13 is appropriately deformed according to the shape of the outer periphery of the flange portion 5. The band 2 is slightly elastically deformed in the extending direction, and the flange portion 5 is securely tightened. This can cope with variations in the dimensions of the glass container. When carrying this beverage server, the fingers are inserted into the annular handle 3 and gripped. Therefore, even if the halves 7 and 8 of the handle 3 are disengaged, the ring of the band 2 does not move. Since it does not open, the glass container 1 is not detached from the handle 3 and is safe.

  The present invention is used as a beverage server for storing coffee, tea, etc., for example.
