However, double plastic sheet molded containers or the aforementioned plastic and paper double molded containers have been proposed as single-use disposable containers, and this structure can be applied to reusable containers as follows. There are some problems. That is, plastic does not feel well on the mouth, and oils of food and pigments dissolved in the food adhere firmly to the container and are difficult to clean, and the surface is easily damaged by repeated cleaning and cannot withstand long-term use.
The present invention has been made in view of the above-mentioned problems, has a good mouthfeel during use, has a good heat insulating property when cooked by a microwave oven, is easy to clean and withstands long-term use. An object of the present invention is to provide a cup for eating and drinking with a smooth outer surface and good touch, and with good decorating properties such as prints.

In this invention, in order to solve the said subject, the cup 1 for eating and drinking is comprised by the inner container 2 made from heat-resistant glass, and the outer container 3 made from a synthetic resin. The outer container 3 is integrally formed of synthetic resin, and a heat insulating space S is formed outside the inner container 2 and is detachably fitted. The inner container 2 has a substantially frustoconical side wall 4 that extends upward and a circular bottom wall 5. The outer container 3 extends in the radial direction of the outer container 3 so as to be concealed inside the lower portion of the side wall 10 in a front view, and a substantially frustoconical side wall 10 that spreads upward, and a circular bottom wall 11. And a plurality of engaging pieces 15 formed so as to be elastically displaceable. The side wall 4 of the inner container 2 includes an annular engagement groove 6 in the lower part of the outer periphery, with which the engagement piece 15 of the outer container 3 is elastically and detachably engaged. The outer periphery of the side wall 10 of the outer container 3 continues smoothly.
Although the present invention has been described with reference numerals in the accompanying drawings, the present invention is not limited to this.

  In this invention, since the inner container 2 is made of heat-resistant glass and the outer container 3 is made of a synthetic resin, and a heat insulating space S is formed between them, the food stored in the inner container 2 and heated in the microwave oven When taking out from the microwave oven while it is hot, the outside of the container is not hot and can be easily taken out with bare hands. Since it is a simple fitting structure that elastically engages the annular engaging groove 6 on the outer periphery of the inner container 2 and the engaging piece 15 on the inner periphery of the outer container 3, it is easy to manufacture and can be obtained at low cost. Since the upper edge portion 9 of the glass inner container 2 extends upward from the upper end of the synthetic resin outer container 3, the glass portion comes into contact with the mouth when serving for food. For this reason, tactile sensation is good and the food can be eaten and eaten comfortably, and when the snout touches the upper edge portion 9 of the inner container 2, the heat of the heated food can be sensed in advance and can be eaten and eaten safely. Since the upper edge portion 9 of the inner container 2 expands in diameter with respect to the lower portion through the step portion 8 and extends further upward, the blow-up of food due to boiling is absorbed at this portion, and spillage is prevented. can do. Since the outer peripheral surface of the inner container 2 and the outer peripheral surface of the outer container 3 are smoothly continuous, the feeling of use is good, and since there is no unevenness, there is little adhesion of dirt, and cleaning is easy. Since the outer periphery of the side wall 10 of the outer container 3 continues smoothly, the decorating property is high.

  Embodiments of the present invention will be described with reference to the drawings. 1 is an exploded perspective view of a cup for eating and drinking, FIG. 2 is a front view of the cup for eating and drinking, FIG. 3 is a sectional view of the cup for eating and drinking, FIG. 4 is a plan view of the outer container, FIG. 6 is a perspective view in which a part of the outer container is cut away.

  The eating and drinking cup 1 includes an inner container 2 made of heat-resistant glass and an outer container 3 made of a synthetic resin that is detachably fitted to the outside of the inner container 2.

  As shown in FIG. 3, the inner container 2 includes a substantially frusto-conical side wall 4 that extends upward and a circular bottom wall 5 that closes the bottom of the side wall 4. An annular engagement groove 6 is formed on the outer periphery of the side wall 4 at a height position close to the bottom wall 5. On the inner periphery of the upper portion of the side wall 4, an annular convex portion 7 for preventing the food N such as instant noodles from floating is formed. An upper edge portion 9 whose outer diameter is enlarged through the step portion 8 is continuous with the upper portion of the annular convex portion 7.

  As shown in FIGS. 3 to 6, the outer container 3 has a side wall 10 and a bottom wall 11 and is detachably fitted to the outer side of the inner container 2. A bottom receiving portion 12 is integrally formed at the lower portion of the side wall 10 so as to be concealed inside the side wall 10 in a front view. The bottom receiving portion 12 includes an annular side wall 13 connected to the inside of the side wall 10 at the upper edge, and the circular bottom wall 11 connected to the lower end of the annular side wall 13. The annular side wall 13 includes an annular main body 14 and an engagement piece 15 that is integrally connected to the main body 14 so as to be elastically displaceable in the radial direction of the outer container. Three engagement pieces 15 are arranged at equal intervals in the circumferential direction, and each of the engagement pieces 15 is formed by being surrounded by an opening 14 a formed in the main body 14 of the annular side wall 13. The three engagement pieces 15 are configured to be elastically engageable and disengageable in the engagement groove 6 of the side wall 4 of the inner container inside the side wall 10.

  The side wall 10 of the outer container 3 terminates immediately below the step portion 8 of the inner container 2, thereby forming a generally smooth outer peripheral surface whose outer periphery is substantially continuous with the outer periphery of the upper edge portion 9 of the inner container 2. To do. On the inner periphery of the side wall 10, a plurality of ribs 16 are formed for forming a heat insulating space S between the outer periphery of the inner container 2.

  An elastic cap 17 for tightening the annular side wall 13 of the bottom receiving portion 12 from the outer periphery is detachably fitted to the bottom portion of the outer container 3. The elastic cap 17 includes a circular bottom wall 18 having an opening 18 a and a tightening ring 19 rising from the edge of the bottom wall 18. By tightening the annular side wall 13 from the outer periphery, the tightening ring 19 prevents the elasticity of the engagement piece 15 from weakening with time and preventing the engagement force with the engagement groove 6 of the inner container 2 from weakening. Further, the bottom wall 18 increases the friction between the cup mounting surface, such as the upper surface of the table, and the bottom of the cup 1 and improves the stability.

FIG. In the figure, components equivalent to those of the previous embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In the cup 1 of this embodiment, the engagement piece 15 is formed so as to rise from the bottom wall 11 inside the lower portion of the side wall 10 of the outer container 3. The engagement piece 15 has a root portion 15a having three surfaces, a back surface (a surface corresponding to the outer side in the radial direction of the bottom wall 11) and both side surfaces (surfaces corresponding to the circumferential direction of the bottom wall 11), surrounded by the opening 11a and the notch 11b. The base portion 15a is separated from the bottom wall 11 and is curved to obtain good elasticity. The root portion 15a is divided into two parts by a central opening 11c. Reference numeral 20 denotes a rib, which forms a heat insulating space S between the bottom wall 11 and the inner container 2 when fitted to the inner container 2.

  For example, as shown in FIG. 3, the eating and drinking cup 1 is filled with instant noodles N and water W, cooked in a microwave oven, then taken out, and the noodles are transferred to a container such as other tableware. Put it on the table without using it, and use it for food. The inner container 2 is made of heat-resistant glass and the outer container 3 is made of synthetic resin, both of which have low microwave loss, and are not easily heated by a microwave oven. Moreover, since the heat insulation space S is formed between both, when taking out the food stored in the inner container 2 and heated by the microwave oven from the microwave oven while it is hot, the outside of the container is not hot, and it is bare-handed. It can be easily taken out. Since it is a simple fitting structure that elastically engages the annular engaging groove 6 on the outer periphery of the inner container 2 and the engaging piece 15 on the inner periphery of the outer container 3, it is easy to manufacture and can be obtained at low cost. Since the upper edge portion 9 of the glass inner container 2 extends upward from the upper end of the synthetic resin outer container 3, the glass portion comes into contact with the mouth when serving for food. For this reason, tactile sensation is good, and it is possible to eat and drink comfortably, and by touching the upper rim portion 9 of the inner container 2 with the snout, it is possible to sense the heat of the heated food in advance and eat and drink carefully and safely. it can. Since the upper edge portion 9 of the inner container expands in diameter with respect to the lower portion via the step portion 8 and extends further upward, the blow-up of food due to boiling is absorbed at this portion, and spillage is prevented. be able to.
