Abstract

PROBLEM TO BE SOLVED: To enable miniaturization excellent in portableness, reduce a manufacture cost, and enable high airtightness by detachably attaching a vessel part constitution member having airtightness to a part of a case. SOLUTION: A first rear cover 12 is fitted to the threaded part of a shell 11, a second rear cover 18 is screwed downward of the same threaded part, and a gap part is formed between the rear covers 12, 18. A user can insert, for instance, a medicine such as the tablet of a heart drug or a minute material such as a dressing tool necessary for portable always in the gap part. The user inserts and takes out the minute material by detaching screwing of the rear cover 18 by hand, a spanner and the like, and thereafter the rear cover 18 may be fitted to the threaded part of the shell 11 again. Since a resilient seal member 14 is resiliently pressed in the recess of a face on the lower end of the threaded part downward of the shell 11 and on the outer periphery of the rear cover 18, airtightness is ensured in the vessel. Portableness is excellent and cost reduction is contrived by integrating a module set case and the vessel part inserting the tablet and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable timepiece in which a container such as a tablet or the like, or a minute tool such as a cosmetic tool or a jewel, which can be taken out and used by a user at any time, is detachably attached to a watch case. .

[0002]

2. Description of the Related Art The structure of a conventional portable watch case and the structure of a container for storing an arbitrary object such as a tablet have been shown in FIGS. 2 and 3, 1 is a watch case, 2 is a back cover, 3 is a cover glass, 4 is an elastic seal member, 5 is a dial, 6 is a module, 7 is a container lid, and 8 is a container body. It is. The watch case 1 with the module and the containers 7 and 8 for holding an arbitrary object such as a tablet are separately constructed and connected via a chain or the like, or are carried separately via a chain or a band.

[0003]

However, according to the above-mentioned prior art, the watch case 1 containing the module and the containers 7, 8 are provided.
However, since they are separate bodies, they have a problem that they are inferior in portability and that the manufacturing cost increases. On the other hand, in everyday life, generally, airtightness of 10 atmospheres or more is required as airtightness that can be carried when taking a bath, such as a shower or a bath. It is easy to secure the thickness of the case and the like in order to have airtightness of 10 atmospheres or more while taking into account the properties,
Since the size of the container is limited in terms of portability and design, only airtightness of less than 10 atmospheres can be secured, and when carried during bathing such as showers and baths, water enters the container and tablets in the container are violated. Had problems.

Therefore, the present invention provides a compact portable watch excellent in portability by integrally configuring a watch case containing a module (watch mechanical body) and a container, reducing the manufacturing cost, and further increasing the cost. It is intended to provide confidentiality, for example, waterproofness of 10 atm or more.

[0005]

According to the portable timepiece of the present invention, an airtight container component is detachably attached to a part of a portable timepiece case such as a wristwatch, a wall clock and a pendant watch. It is characterized by. A portable timepiece according to a second aspect is characterized in that, in the first aspect, a back cover is attached to a part of the case with a screw.

A portable timepiece according to a third aspect of the present invention is characterized in that, in the second aspect, the container portion is formed by attaching a container component member to the case by screws outside the back cover.

A portable timepiece according to a fourth aspect is characterized in that, in the third aspect, a screw of the container constituting member is screwed with a screw of a case to which the back cover is screwed.

According to a fifth aspect of the present invention, in the portable timepiece according to the third or fourth aspect, the elasticity is provided between the case and the case on the outer periphery and outside of the screw portion of the case to which the case is screwed. It is characterized in that the seal member is press-contacted.

According to a sixth aspect of the present invention, in the first aspect, the case has a body and a back cover integrated with each other, and a built-in mechanical body is detachable from a cover glass side.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view showing a main part according to the first embodiment of the present invention. To explain the configuration, reference numeral 11 denotes a body constituting a timepiece case, and 12 denotes a first back cover which incorporates a module (a watch mechanical body such as an analog) 16 and is screwed into a screw portion on the back side of the body 11 to seal the case. , 13 is a transparent cover glass for a user to look into a display unit such as a needle, and 14 is pressed between the body 11 and the cover glass 13 to hold the cover glass 13 while ensuring the body 11 is waterproof. Elastic seal member made of synthetic rubber, plastic, or the like.
1 is also press-bonded to the lower surface of the inner periphery,
It is also press-bonded between the outer peripheral upper surface and the lower surface of the screw portion outer periphery of the body 11. Reference numeral 15 denotes a dial placed above the module 16.

Here, a part other than the second back cover 18 constitutes a normal portable timepiece.

The present invention constitutes a confidential container below this ordinary portable timepiece.

In FIG. 1, the above-mentioned first back cover 12 is screwed into the screw portion of the body 11, and a second back cover 18 is further screwed below the same screw portion, so that the first back cover 12 is screwed.
A gap (space) is formed between the second back cover 18 and the second back cover 18. In the space, a user can insert a drug such as a tablet of a heart medicine, which needs to be always carried, or a minute object such as a cosmetic tool or jewelry. The user unscrews these small objects from the second back cover 18 by hand or with a spanner, inserts or removes these small objects, and then puts the second back cover 18 on the body 11 again. What is necessary is just to screw in a screw part. The second back cover 18 is a container constituent member of the first aspect.

Also, the lower end of the threaded portion below the body 11 and the second
Since the above-mentioned elastic seal member 14 is resiliently pressed into the depression on the outer peripheral upper surface of the back cover 18, the inside of the container portion is kept confidential and can provide waterproofness of 10 or more pressures. Since the elastic seal member 14 is arranged below (outside) the screw portion, the user can frequently attach and detach the second back cover 18 to prevent rust of the screw portion which is easily rusted.

The first back cover 12 and the second back cover 18 are
On the other hand, it may be fixed by a bayonet.

Although the first back cover 12 has been described as being separate from the case 11, the two may be integrated into a so-called one-piece case. In this case as well, the back cover which is a container constituent member is provided at the lower end of the case 11 as in FIG. Numeral 18 is screwed and attached with a bayonet.

As described above, by integrating the timepiece case with the module and the container portion for storing an arbitrary object such as a tablet, the portability is excellent and the manufacturing cost can be reduced.

[0018]

As described above, the portable timepiece of the present invention has the following features.
A second air-tight container which has a space for storing an arbitrary object such as a tablet in addition to the first back cover for sealing the module.
By providing the back cover, it is possible to prevent the water from entering the container part and protect the objects contained in the container part from the external environment even when the portable terminal is carried at the time of entering water such as a shower and a bath in daily life, by being excellent in portability. In addition, the manufacturing cost can be reduced.
