Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a wide-mouth, relatively large-capacity liquid container, such as a portable cooler.

(Prior Art) FIG. 8 shows a conventional wide-mouth, large-capacity liquid container called a portable cooler. In the conventional liquid container shown in FIG. 8, near the outer periphery of the lower surface of the shoulder member 105 of the liquid container main body 101, there is an outer peripheral wall 151 constituting the outer surface of the main body that is fitted with the upper end of the outer shell 104, and a liquid supplying liquid container. Three annular walls are formed: an inner circumferential wall 152 forming the opening 108 and an intermediate circumferential wall 157 provided at an intermediate portion between the outer circumferential wall 151 and the inner circumferential wall 152. Moreover, the shoulder member 1
In the inner annular groove 158 formed between the inner circumferential wall 152 and the intermediate circumferential wall 157 of 05, the upper end 17 of the wide-mouthed inner container 107 (the inner diameter of the body and the opening diameter are approximately the same diameter) is disposed.
1 is fitted into the outer annular groove 159 formed between the intermediate circumferential wall 157 and the outer circumferential wall 151, and an engaging protrusion for preventing the handle 110 from falling off is provided in the inner end of the shaft portions 112, 112 of the handle 110. The portions 113, 113 are held in position in the inner and outer directions.

(Problem to be Solved by the Invention) However, in the conventional wide-mouth, large-capacity liquid container shown in FIG.
An intermediate peripheral wall 157 is formed between the outer peripheral wall 151 and the inner peripheral wall 152 to form an outer annular groove 159 for holding the engaging protrusion 113 of the handle shaft 112 in position. In the case where the intermediate peripheral wall 157 is formed, there is a problem that the structure of the shoulder member 105 becomes complicated and the molding of the shoulder member 105 becomes troublesome. Furthermore, in the liquid container shown in FIG. 8, the upper end 171 of the inner container 107 is simply fitted into the inner annular groove 158, so that the upper end 171 of the inner container and the lower surface of the shoulder member (the inner annular groove 1
58), and in particular, if there is a dimensional error (molding error) between the groove width of the inner annular groove 158 and the thickness of the inner container upper end 171, the sealing performance will be even worse. Become.

In view of the above-mentioned problems, the present invention simplifies the structure of the shoulder member, and utilizes an outward flange provided at the upper end of the inner container to provide an engaging protrusion for preventing the handle shaft from slipping out within the shoulder member. The objective is to secure a space for holding the inner container and to improve the sealing performance between the upper end of the inner container and the lower surface of the shoulder member.

(Means for Solving the Problems) The present invention accommodates a wide-mouthed inner container in which the inner diameter of the body and the opening diameter are approximately the same diameter inside the liquid container body, and uses a shoulder member of the liquid container body to hang and hold the liquid container. In a liquid container having a handle that is rotatable in an arc, an outward flange is formed at the upper end of the inner container, and an inclined surface is formed on the inner periphery of the shoulder member so that the distance becomes narrower toward the top. An annular groove is formed, and the outward flange of the inner container is fitted into the annular groove via an elastic packing that is applied to the inclined surface, and a retaining engagement provided on the shaft of the handle is formed. The mating protrusion is located in a space formed between the inner container and the shoulder member by fitting the outward flange of the inner container into the annular groove.

(Function) According to the liquid container of the present invention, since the outward flange formed at the upper end of the inner container is fitted into the annular groove provided on the inner periphery of the shoulder member via the elastic packing, both (the contents The sealing performance between the upper end of the container and the inner surface of the annular groove is ensured. Moreover, since the annular groove is formed with an inclined surface whose spacing becomes narrower as it goes upward, and the elastic packing is installed in contact with the inclined surface, when the liquid container is assembled, the inclined surface This compresses the elastic packing, further improving sealing performance. In addition, since the outward flange of the inner container is fitted into the annular groove, the outward flange, which is normally provided at the upper end of the inner container, can be used to create a handle between the inner container and the shoulder member in the annular groove. A space for holding the engagement protrusion of the shaft can be secured. Since the engaging protrusion of the handle shaft is held in the space, the single annular groove can be used both for inserting the upper end of the inner container and for holding the position of the engaging protrusion on the handle shaft. .

(Embodiments) Several embodiments of the present invention will be explained with reference to Figs. 1 to 7. Figs. 1 to 3 show the first embodiment of the present invention, and Fig. 4 shows the same embodiment. 2 examples,
5 and 6 show a liquid container according to the third embodiment, and FIG. 7 shows a liquid container according to the fourth embodiment. In each of these embodiments, a wide-mouth, large-capacity liquid container, such as a so-called portable cooler, is employed.

The liquid container of the first embodiment shown in FIGS. 1 to 3 has a shoulder member 5 and a bottom member 6 made of synthetic resin attached to the upper and lower parts of the outer body 4 made of metal by force fitting, respectively. A liquid container main body 1 having a metal inner container 7 housed in an outer case 3, a lid body 2 for opening and closing a liquid supply port 8 of the liquid container main body 1, and a handle 10 for hanging. It is configured.

The inner container 7 is a wide-mouthed container in which the inner diameter of the body and the opening diameter are approximately the same. An outward flange 71b having a small width (width A) is formed at the upper end 71 of the inner container 7.

A large-diameter liquid supply port 8 is formed in the center of the shoulder member 5, and the lid 2 is screwed into the liquid supply port 8.

A single annular groove 53 that is recessed upward at the same position as the upper end 71 of the inner container 7 is formed near the outer periphery of the lower surface of the shoulder member 5 . This annular groove 53
is formed between an outer circumferential wall 51 connected to the upper end of the outer shell 4 and an inner circumferential wall 52 forming the liquid supply port 8 therein. Moreover, the groove width dimension of this annular groove 53 is as follows:
As shown in FIG. 2, the thickness (groove width B) of the upper end portion 71 of the inner container is considerably larger than the thickness A (width of the outward flange 71b). For example, while the thickness A of the inner container upper end portion 71 is 3 to 4 mm, the groove width dimension B of the annular groove 53 is approximately 7 to 10 mm.

Further, the annular groove 53 is formed with an inclined surface 59 whose interval becomes narrower as it goes upward (slanted outwardly downward).

In the first embodiment, the inner container 7 has the outer flange 71b of the upper end 71 covered with the annular elastic packing 18, and the upper end 71 (outward flange 71b) to which the elastic packing 18 is attached. It is press-fitted into the annular groove 53 from the lower surface side of the shoulder member 5. At this time, the elastic packing 18
A part of the upper surface is pressed against the inclined surface 59 of the annular groove 53, and when the elastic packing 18 is pressed against the inclined surface 59 in this way, the compressive action on the elastic packing 18 becomes large and the sealing performance is improved. do.
The elastic packing 18 also has an annular lip portion 19 (in this embodiment, formed on the inner circumferential side of the packing) that springs so that the horizontal width of the longitudinal section is slightly larger than the groove width B of the annular groove 53 in the free state. ), so that when the upper end portion 71 with a seal of the inner container 7 is press-fitted into the annular groove 53, the lip portion 19 is elastically deformed and comes into watertight contact with the outer surface of the inner circumferential wall 52 of the shoulder member. It's summery. By providing the elastic lip portion 19 on the elastic packing 18 in this way, sufficient sealing performance can be ensured even if a slight molding error occurs in the diameter, width, etc. of the inner container upper end 71 or the annular groove 53. Ru. The inner container 7 has its upper end 71 fitted into the annular groove 53 of the shoulder member 5, and the bottom surface of the inner container 7 is supported from below by the bottom member 6.

When the inner container 7 is installed in the outer case 3, the outward flange 71b is fitted into the annular groove 53, so that the outer surface 71a of the upper end portion 71 of the inner container and the outer peripheral wall 51 of the shoulder member 5 are A space S (distance C) is provided between the inner surface 51a and the engaging protrusion of the handle shaft, which will be described next.

The handle 10 is shaped like an arc having a length of approximately half the circumference. Shaft portions 12, 12 are provided at both ends of the handle 10, respectively, to protrude inwardly, and furthermore, at the tips (inner ends) of each of the shaft portions 12, 12, a retainer protrudes outward in the radial direction. Engagement projections 13, 13
is formed.

On the other hand, shaft holes 55, 55 are formed in opposing side surfaces of the shoulder member outer peripheral wall 51, respectively. A notch 56 is formed at the edge of each of the shaft holes 55, 55 into which the engaging protrusion 13 of the handle shaft is inserted. As shown in FIG. 3, the engaging protrusions 13 on the handle 10 side completely overlap with the notch 56 of the shaft hole 55 within the normal use range (angle range of 180°) of the handle 10. They are each positioned so that there is no

The liquid container main body 1 and handle 10 are assembled as follows. First, the annular groove 5 of the shoulder member 5
Upper end 7 with elastic packing 18 of inner container 7 inside 3
1 (outward flange 71b), then both end shaft portions 12, 12 of the handle 10 are inserted into the shoulder member outer peripheral wall 51.
After inserting the outer shell 4 into the shaft holes 55, 55 (using the elasticity of the handle), the upper end of the outer shell 4 is forcefully fitted to the shoulder member outer peripheral wall 51, and the outer shell 4 and the side wall 70 of the inner container 7 are The assembly of the liquid container main body 1 and the handle 10 is completed by filling the space between them with a heat insulating material 15 and first forcefully fitting the bottom member 6 to the lower end of the outer body 4. In the assembled state of the liquid container main body 1, the inner container 7 is held between the bottom member 6 and the shoulder member 5. Even if there is a slight error (determined by fitting), the error can be absorbed by the elastic packing 18, and the inner container 7 can be held and fixed securely. Furthermore, since the upper end 71 of the inner container 7 is fitted into the annular groove 53 via the elastic packing 18, the seal between the inner container upper end 71 and the inner surface of the annular groove 53 is ensured. In particular, since the inclined surface 59 is formed in the upper part of the annular groove 53 and the elastic packing 18 is applied to the inclined surface 59, the compressive action of the elastic packing 18 is increased and the sealing performance is further improved. Moreover, in the annular groove 53, a space S is formed between the outer surface 71a of the inner container upper end 71 and the inner surface 51a of the shoulder member outer peripheral wall 51 by fitting the outward flange 71b, An engaging protrusion 13 provided at the inner end of the handle shaft 12 is held in position within the space S. In this way, by simply fitting the outward flange 71b into the annular groove 53, the space S for holding the position of the engaging protrusion 13 can be formed, and a special space S for holding the position of the handle shaft can be formed on the shoulder member 5 side. There is no need to form a peripheral wall.

The lid body 2 is formed by accommodating a heat insulating material 23 between a top lid 21 and a bottom lid 22. The top cover 21 and the bottom cover 22 are integrated by force-fitting each other at the central portion (section D) and by ultrasonic bonding (section E) at the outer periphery.

In the second embodiment shown in FIG. 4, an elastic packing 1 seals between the shoulder member 5 and the upper end portion 71 of the inner container.
8 is installed with its entire upper surface in contact with an inclined surface 59 formed on the ceiling of the annular groove 53, and the inner container upper end 7 is placed on the lower surface of the elastic packing 18.
The upper surface of the flange 71b of No. 1 is pressed against the upper surface of the flange 71b. or,
In this second embodiment, the outer end surface of the engagement protrusion 13 provided on the handle shaft 12 is brought into contact with the lower surface of the flange 71b of the upper end portion 71 of the inner container to prevent the inner container 7 from shifting downward. That's what I do. A plurality of ribs 61 supporting the bottom corner portion 72 of the inner container 7 are formed at appropriate intervals on the upper surface of the bottom member 6 at a position near the outer periphery thereof. Moreover, the upper part of the outer body 4 and the shoulder member outer peripheral wall 5

It is fixed at 2.

The third embodiment shown in FIGS. 5 and 6 and the fourth embodiment shown in FIG. 7 each have an inner container downward movement regulating structure to prevent the inner container 7 from shifting downward. .

In the third embodiment shown in FIGS. 5 and 6, a cylindrical bushing 81 having a shaft hole 55 is fitted into a hole 57 formed in the outer peripheral wall 51 of the shoulder member for inserting the handle shaft 12. The shaft portion 12 of the handle 10 is inserted into the shaft hole 55 in the bush 81. The outer peripheral surface (upper surface) of the bush 81 is in contact with the lower surface of the flange 1b of the upper end portion 71 of the inner container.
This prevents the inner container 7 from shifting downward. Note that a notch 56 is formed on the edge of the shaft hole 55 of the bush 81 for engaging the engagement protrusion 13 of the handle shaft portion 12.

In the fourth embodiment shown in FIG. 7, an outwardly facing claw portion 86 is formed at the vertically intermediate portion of the locking member 85, and a window-shaped claw is formed to lock the claw portion 86 on the outer peripheral wall 51 of the shoulder member. The receiving portion 59 is formed to lock the claw portion 8 of the locking member 85.
6 is locked in the claw receiving part 59, the locking member 8
5 to the flange 71 of the inner container upper end 71.
b It is made to come into contact with the lower surface. Note that a hole 88 through which the handle shaft 12 is inserted is formed at a position in the locking member 85 where the handle shaft 12 reacts, and the handle shaft 12 is exposed inward through the hole 88. .

(Effect of idea) The liquid container of the present invention has the following effects.
