Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a double-walled cold insulation mug that is used by filling the space inside the wall with water.

[0002]

[Prior art]

 A conventional double-walled cold insulation mug is made of transparent plastic and consists of a combination of two molded products, an inner container and an outer container with a handle, with a space filled with water between the combinations. However, a water injection hole was provided on the bottom wall of the outer container, and the injection hole was formed as a female female, and a plug for sealing it was formed on a male screw with a head.

The user is filled with water, and when pouring beer, it is put in a refrigerator in advance to freeze the water. If this is the case, beer can be kept cold for a long time, so it tends to be used frequently in restaurants, especially in summer, and it is also welcomed for drinking at home.

[0004]

[Problems to be solved by the device]

 At the time of shipment, the products are generally packaged one by one, but with the conventional double-walled cold mug, the handle is integrally molded, so the packaging is compact and compact. There was also a problem that it was not possible, and there was a wasted space in the box due to the handle protruding sideways.

Regarding the appearance, after the beer has been drunk, it is common to look into the back side due to its unusualness. In that case, a male screw with a head is screwed into the water injection hole. It looks explicit. Moreover, because it is a mechanical component with a solid image, it is easy to feel disillusioned and upset, and because the position of the stopper is at the bottom, it is easy to see through from the inside, and when it is seen, resistance There was also a complaint that I couldn't feel the openness of refreshing beer.

Regarding the injection of water, there is a risk that a proper amount of water or more will be put into the space between the inner container and the outer container, in which case the mug may be destroyed due to the expansion of the volume accompanying freezing of the water. There was also.

In view of the above situation, the present invention has a separate handle, so that it can be packaged compactly without being hindered by it, and by attaching the handle, a water injection hole is provided. The purpose was to provide a double-walled cold mug that is well-sealed with a stopper. In addition, the purpose was to prevent the breakdown of the jug due to the expansion of the volume accompanying the freezing of water.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a double-walled cold mug made of transparent plastic with a space filled with water by a combination of an inner container and an outer container. A bow-shaped handle is formed separately so that it can be assembled, and an L-shaped leg piece that hangs on the bottom of the outer container is hung vertically on the lower end of the handle. In addition to forming a joint part to be connected, a water injection hole was opened on the side surface of the lower end, and a plug tightly fitted to the injection hole was projected on the leg piece to form a double-walled cold insulation mug.

In addition, the bottom wall of the outer container may be easily elastically deformed so that the bottom wall of the outer container can absorb the expansion of the volume accompanying the freezing of water, and the bottom wall of the outer container may be sequentially formed to be thin.

[0010]

[Action]

 Since the double-walled cool mug is constructed as described above, it can be stored in the inner container and packaged at the time of shipping without attaching the handle.

The user attaches the handle after injecting water from the injection hole. Then, the plug protruding from the leg piece of the handle tightly fits into the injection hole, and the injection hole is sealed while the plug is not exposed. Also, at that position, in a normal line of sight, the light from the injection hole or stopper is abruptly inclined with respect to the surfaces of the inner container and the outer container. Even if it is transparent, it impairs vision, and it also interferes with the handle, so the presence of injection holes and plugs is visually invisible.

[0012]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

The drawings show an embodiment, in which a double-walled cold insulation mug is composed of a combination of an inner container 1, an outer container 3 and a handle 5 each made of transparent plastic. And has a space 6 filled with water between the inner container 1 and the outer container 3.

The inner container 1 has a single edge wall 7 formed at the upper end so that the mouth feel is good and the edge is made single, and the outer container 3 is located below the single edge wall 7. It is doubled in and. For this reason, the single-edge wall 7 is formed to have substantially the same diameter as the upper end of the outer container 3, and a step portion 9 with which the upper end of the outer container 3 is attached is provided at the lower end thereof, and the lower part has a smaller diameter. A space 6 is formed between the outer container 3 and the outer container 3.

In order to attach the handle 5 to the outer container 3, the joint portion 11 of the handle 5 is projected at one end of the outer container 3 as a part thereof, and the joint recess 13 of the handle 5 is provided at the lower end thereof. And a water injection hole 15 is provided in the joint recess 13 at the lower end of the side wall. The thread bottom 16 is formed by raising the bottom wall 19 at the periphery.

The connection between the joint portion 11 of the outer container 3 and the upper end of the handle 5 is, so to speak, similar to a “drop hook joint” found in a joint structure in a wooden building. 5, a connecting concave portion 17 is formed, and the connecting concave portion 17 is formed into a dovetail shape having a front opening, and a hook-shaped connecting convex portion 18 is formed on the upper end surface of the handle 5. Therefore, when attaching the handle 5, if the lower end is hooked on the bottom of the outer container 3 and then the upper end is hooked on the joint 11 while elastically deforming, the hook is held against elasticity. Therefore, a stable bonded state that does not come out is obtained.

The joint recess 13 at the lower end of the outer container 3 is provided so that the handle 5 can be attached to the handle 5 with good appearance and stability, and the outer wall is depressed until the thread bottom 16 is removed. An engaging groove 21 of the handle 5 is formed in the bottom wall 19 along the cutout portion of the thread bottom 16.

The handle 5 has an arcuate shape similar to that of an ordinary jug, but as described above, the connecting convex portion 18 is provided at the upper end and the leg piece 25 is vertically provided at the lower end. On the piece 25, a plug 26 that tightly fits into the injection hole 15 is provided on the inner surface, and a reversing protrusion 27 that engages with the locking groove 21 is formed at the lower end. Due to this catch, the plug 26 is held in the injection hole 15 so that it cannot escape. The handle 5 has the same size as that of an ordinary jug, but can be stored in the inner container 1 with some room.

The injection hole 15 and the plug 26 are formed so that their diameters are sequentially reduced inside and are closely fitted. Further, in this way, when the handle 5 is attached, the plug 26 can be easily inserted into the injection hole 15 while hooking the reversing protrusion 27 of the leg piece 25 in the locking groove 21. it can. Then, the catch of the leg piece 25 is held by the elastic force with which the handle 5 is pulled by the joint 11. Further, an O-ring 29 is fitted on the base of the plug 26 to improve watertightness. The outer container 3 and the handle 5 may be bonded to each other in order to strengthen the bond.

In FIG. 2, the path of the light from the stopper 26 is shown in the direction of the dashed line, where the line of sight 28 is cast from the inside toward the stopper 26. From the law of reflection and refraction, the light 3 The plug 26 cannot be seen, because 2 is reflected on the outer surface of the inner container 1 and does not reach the eyes 30. The same phenomenon occurs in the outer container 3.

Regarding the combination of the inner container 1 and the outer container 3, a groove 31 is formed in the step portion 9 of the inner container 1, and a ridge that fits into the groove 31 is formed on the upper end surface of the outer container 3. 33, which are glued together at their joints.

Since the bottom wall 19 of the outer container 3 is not only a raised bottom but is formed to have a thinner wall in the central portion, the bottom wall 19 is pushed downward when the water in the space 6 expands due to freezing. By being lowered, the expansion of the volume of water is absorbed.

[0023]

[Effect of device]

 As described above, the present invention has the following excellent effects.

1) When the double-walled cold insulation mug is shipped, by putting the handle inside, it can be packaged compactly so as to be advantageous for transportation and storage.

2) Although the handle is a separate body and it takes a lot of time to install it when using it, the water injection hole is sealed with a stopper at the same time when the handle is installed. Therefore, the user can save the trouble.

3) The water injection hole and its plug are not exposed and are in places where it is difficult to see through, so the appearance is very good.

In addition, when the bottom wall of the outer container is easily elastically deformed and is formed to have a thin wall in the central portion (claim 2), the expansion caused by freezing of water is absorbed by the elastic deformation of the bottom wall. , It is possible to prevent the jug from being broken during freezing.
