Description

[Detailed description of the invention] Industrial field of application The present invention relates to a magic bottle of the type that pours out the liquid content at an angle, and in particular, the invention relates to a magic bottle that pours out the liquid content at an angle. This invention relates to an improvement in a magic bottle having a structure in which the peripheral edge of the upper opening of the inner bottle is pressed against the lower surface of the peripheral edge via a gasket.

BACKGROUND OF THE INVENTION Generally, magic bottles are used by housing an inner bottle, which is a vacuum double bottle made of glass, inside the outer case, and storing the liquid inside the inner bottle. Therefore, it is necessary for the inner bottle of the magic bottle to be securely held within the exterior body.

Therefore, as a means of holding the inner bottle in the outer case,
The periphery of the upper opening of the inner bottle is brought into contact with the lower surface of the periphery of the opening formed in the shoulder of the exterior body through the packing, and the push-up body is screwed onto the bottom of the exterior body to push it up. The inner bottle is tightened with the user's body, and the inner bottle is tightened and held with the packing and the pushing body.

In this structure, when assembling the magic bottle, it is necessary to attach a gasket to the periphery of the opening in the shoulder in advance, so a short cylindrical part is hung down from the lower surface of the periphery of the opening. A gasket is fitted into a cylindrical portion to hold it, and the length of the short cylindrical portion is several times the thickness of the gasket so that the gasket does not fall off.

Problems to be Solved by the Invention However, with this structure, since the gasket is located at the upper end of the long short tube, there is a gap between the short tube below the gasket and the inner bottle. A gap is formed, and if the magic bottle is tilted when injecting the liquid, the liquid will enter this gap and cannot be drained. In particular, if you put coffee, soup, etc. into the magic bottle, these things will get into the gap, and even after use, a small amount of the liquid will remain, which may rot and cause a bad odor, or putrefying substances. This is extremely unhygienic as it may get mixed into the liquid content the next time it is used.

The present invention was devised in view of the above circumstances, and is intended to prevent a gap from forming between the short cylindrical portion and the inner bottle in the above-mentioned magic bottle, and to prevent the liquid from entering and staying there. The purpose of this invention is to provide a structure for a magic bottle that will not deteriorate or rot.

Means for Solving the Problems The present invention provides an inclined pouring mold in which the periphery of the opening of the inner bottle is pressed against the lower surface of the periphery of the opening of the shoulder of the exterior body via a packing. In the gift bottle, a short cylindrical part having a length approximately equal to the thickness of the packing is hung from the periphery of the opening of the shoulder part, and a rib is protruded from the outer periphery of the lower end of the short cylindrical part, It is characterized in that the gasket is fitted and held on the outer periphery of the cylindrical portion.

The present invention will be explained below with reference to the drawings. FIG. 1 shows a magic bottle of the present invention, in which an inner bottle 2, which is a vacuum double bottle, is housed in an outer case 1, and a stopper 5 is inserted into an opening 4 of a shoulder 3 of the outer case 1. It is screwed together so that it can be opened and closed.

As shown in FIG. 2, on the lower surface of the periphery of the opening 4,
A short cylindrical portion 7 having a length approximately equal to the thickness of the packing 6 is vertically provided, and a plurality of ribs 8 are intermittently protruded from the outer periphery of the lower end of the short cylindrical portion 7. The gasket 6 is fitted onto the outer periphery of the short cylindrical portion 7 and is held by the ribs 8 so as not to fall off from the short cylindrical portion 7.

When assembling the magic bottle of the present invention, the gasket 6 is fitted and held in the short cylinder part 7 of the shoulder part 3 in advance, and then the inner bottle 2 is housed in the exterior body 1 and the upper The peripheral edge of the opening 9 is brought into contact with the packing 6, a push-up body is screwed onto the bottom of the exterior body 1, the push-up body is tightened to press the inner bottle 2 against the packing 6, and the push-up body and the packing 6 are brought into contact with each other. It is housed and held within the exterior body 1.

Effects of the invention According to the invention, the length of the short cylindrical portion 7 is
Since the thickness is approximately equal to the thickness of the bottle 2, the gap between the short cylindrical portion 7 and the inner bottle 2 is filled with the packing 6, and the content liquid does not enter and stagnate in this gap. Therefore, the remaining content liquid will not rot and emit a bad odor, nor will it mix with the content liquid to be used next time, making it sanitary.

In addition, if the short cylindrical part 7 is short, the packing 6 tends to fall off from the short cylindrical part 7 when assembling the magic bottle, making the assembly difficult. Since ribs 8 are formed,
The packing 6 is held by the ribs 8, and can be easily assembled without falling off from the short cylindrical portion 7.

Note that the ribs 8 in the present invention may be provided intermittently in a plurality of ribs 8 as shown in the drawings, but may also be formed over the entire circumference of the short cylindrical portion 7. Also, the rib 8 only needs to be able to hold the packing 6, and its height should be 0.2~
Approximately 0.4mm is sufficient. Therefore, when molding the exterior body 1, this rib 8 becomes an undercut, but there is no need to make it into a special split mold, and it is possible to remove it by force, which does not result in an increase in cost. Nor.
