Description

  The present invention relates to a double glass container and a method for manufacturing the same, and more specifically, the body circumference to be gripped by a hand is double, heat is not easily transmitted, and a constant width of the opening is single. The present invention relates to a double glass container which is thin and easy to drink, and whose contents are sensitive to contact with the lips, and a method for producing the same.

  Conventionally, various types of double containers have been developed and used, but most of them are made of synthetic resin, and a double glass container is not realized.

For example, the main body 20 of the mug 10 having the outer body portion 21, the inner body portion 22, the bottom portion 23, the peripheral edge portion 24, and the handle 25 is integrally formed of a transparent synthetic resin (for example, acrylic resin). A decorative space 50 is formed between the inner peripheral surface 21a of the outer trunk portion 21 and the outer peripheral surface 22b of the inner trunk portion 22, and a sheet-like ornament is formed in the decorative space 50 via a lower insertion / extraction opening 51. 30 is accommodated so that the design of the ornament 30 can be seen from the outside through the outer body 21. By forming the main body 20 integrally and providing the insertion / removal port 51 below, the thickness A of the peripheral portion is determined by the thickness of the upper end edge 21e of the outer trunk portion 21 and the thickness of the upper end edge 22c of the inner barrel portion 22. The added thickness, that is, the one that can be reduced to the minimum necessary (see Patent Document 1), the outer cylinder and the inner cylinder are combined to have a certain space portion, and the main body portion is configured, A sensor unit in the space, a battery that supplies power according to the reaction of the sensor, a control unit that receives a signal from the sensor, a melody chip that receives a signal from the control unit and sends a specific melody signal, and the melody chip It is similar to a spherical shape that can be fitted in the inner cup 10, which has a speaker diaphragm that receives a coming signal and emits sound (see Patent Document 2), an inner cup 10 in which the inner layer is a container for water accumulation Transparent outer cup 20 The a, of, has a space 11 which can be filled with liquid between outer cup 10 and 20, the inner at the lower end of the outer cup 20 may be attached to the bottom seat 30 having a color different from the outer cup 10, 20. The surface of the inner cup 10 may be printed with beautiful designs 101 and characters of various colors, and an active object may be placed in the filling liquid between the inner and outer cups 10, 20. The periphery of the lens has a shape similar to a convex lens, and the active object in the design 101 and the filling liquid can be an interesting change design that is enlarged and deformed by the principle of enlargement. have. Further, there are disclosed ones that exhibit the three-dimensional effect of the decorative pattern 31 that is transparent and shine, and can enhance the effect of practical use and decoration (see Patent Document 3).

  However, the one described in Patent Document 1 is formed by double-folding at the opening using a transparent resin, and the thickness of the upper opening can be minimized. Although there is a description, it is folded at the opening, there is a limit to the thickness to be thinned, it does not become thin, and the one described in Patent Document 2 has a double structure by a plastic material, A melody chip or the like is provided in the interval so that a sound can be produced, but the opening is double thick, and the one described in Patent Document 3 is a transparent outer cup 20. The inner cup 10 is fitted into the inner and outer spaces 10 and 20, and the space 11 is filled between the inner and outer cups 10, 20. The opening is made thin with the inner diameter of the inner cup 10 and the outer periphery of the double-layer container being thin. Cannot be formed That is, the thick opening as shown in FIG. 1 (a) is difficult to drink the contents, and the thick opening has low heat conduction, so the contents are put in the mouth even though the contents are hot. Has occurred frequently. In addition, in decanters for wine and sake bottles for liquor, heat retention is effective, but the spout is thick, so it is not easily used when pouring.

  As a result of diligent study in view of the above problems, the double glass container of the present invention is provided with an outer glass container and an inner glass container having an opening on the upper side, and the outer glass container is provided with an inner glass container. An opening edge of a certain width downward from the opening of the outer glass container is projected from the opening of the inner glass container, and the outer peripheral edge of the opening of the inner glass container is welded to the lower end of the opening edge. In addition, the body portion and the bottom portion are doubled. Further, the manufacturing method includes a step of providing an outer glass container and an inner glass container each having an opening on the upper side, and an inner glass container. A step of fixing the supporter with the tool inserted and supported, a step of interior with a gap between the outer glass container and the inner glass container, and an opening edge of a certain width from the opening of the outer glass container The process of heating the provided lower side , The step of squeezing the heated portion in contact with the rotating roller or the rotary mold, and the step of welding the inner side of the outer glass container squeezed by the squeezing step and the outer peripheral edge of the opening of the inner glass container, In addition, the following manufacturing method includes a step of including an outer glass container having an opening on the upper side and an inner glass container in which a support part is extended via a cutting weakened part that forms an opening on the upper side. A step of fixing the support portion of the inner glass container in a state of being supported by the chuck, a step of interior mounting with a gap between the outer glass container and the inner glass container, and an opening of a certain width from the opening portion of the outer glass container A step of heating the lower side provided with the edge, a step of squeezing the heated part in contact with the rotating roller or the rotary mold, and cutting the fragile portion of the inner glass container to open upward Forming process and A step of welding the outer peripheral edge of the opening of the inner and the inner glass container outer glass container that focus the step of squeezing is intended to include.

  Further, the double glass container of the present invention has an opening edge of a constant width downward from the opening of the inner glass container, protruding from the opening of the outer glass container, and the opening of the outer glass container at the lower end of the opening edge. The inner peripheral end of the part is welded to make the body part and the bottom part double, and further, the manufacturing method is provided on the outer side from the opening part of the inner glass container to the lower side provided with the opening edge of a certain width. The process of positioning and heating the opening of the glass container, the process of squeezing the heated part in contact with the rotating roller or the rotary mold, and the inner periphery of the opening of the outer glass container squeezed by the squeezing process And welding the end and the outside of the inner glass container.

  The double glass container of the present invention and the method for manufacturing the double glass container are formed by forming an opening edge having a single width at the opening of the outer glass container or the inner glass container, and making the body and the bottom double. Yes, when the contents are poured, the heat insulation layer of the air layer makes it difficult for heat to pass through the body and the bottom, and when the container is gripped, it is safe to transfer heat, and hot things are always hot, cold things are always cold In addition, it is easy to drink because it has a single open edge, and the temperature of the contents can be easily detected by the lip sensation. It has been conventionally difficult to attach a spout, and there has been no idea of this, and it is a highly practical invention having a very effective effect.
