Easy-operated bottles

Abstract

A bottle which bottom has a female pattern which is a recessed space which can engage with an inserted male pattern which protrudes from the top of a cap; a bottle which bottom has a recessed space which cross-section resembles this of a cap and which can engage with an inserted cap; and a bottle which bottom has a female pattern which is a recessed space which cross-section resembles this of a cap which has a male pattern protruding from its sides and which can engage with the male pattern of the cap.

Description

BACKGROUND OF THE INVENTION

1. FIELD OF THE INVENTION

This invention relates to easy-operated bottles and particularly to bottles with screwed on/off caps that can engage with shapes on the bottoms of other bottles to provide additional twisting arms for generating additional torque to facilitate easy opening/closing of the bottles.

2. DESCRIPTIONS OF THE PRIOR ARTS

No prior art related to easy-operated bottles was found.

SUMMARY OF THE INVENTION

Ordinary bottles have relatively small diameter caps. When twisted on or off of the caps, much force is needed because the momentum arms are relatively small due to the relatively small diameter caps. The relatively small diameter caps are hard to be handled by hands. This is especially true for those who have relatively weak hands or injured wrists. For these people tools can be used to operate the caps. But, tools might not be readily available when needed. Therefore, easy ways to operate the bottles are sought.

The invented devices involve modifying the caps and the bottles so that with two bottles the caps can be easily twisted on or off. Specifically, each bottom of the invented devices will have a recessed space which can engage with a cap of another invented device. When two bottles of the invented devices are stacked together, the bottle above will help the bottle below to twist on or off its cap. The user can handle the operations of the bottle easily because the user will not have to handle the relatively small cap directly,

These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:

GENERAL DESCRIPTION

Three variations of the invented device are introduced herein in this specification.

Referring to FIGS. 1 and 2, the first variation of the invented easy-operated bottle, 1, is a bottle which cap, 2, has a male pattern 4 which consists of short plates extruding from the top of the cap. On the bottom, 3, of the bottle is a female pattern, 5, which consists of recessed areas which can engage with an inserted male pattern of a cap.

Referring to FIG. 3, when opening the cap of the invented device, the user will firstly stack two bottles, 6 and 7, together. The user will have the male pattern of the cap of the bottle at the bottom to engage with the female pattern on the bottom of the bottle at the top. The cap of the bottle, 7, at the bottom is the one to be opened. Then the user applies some forces, 8 and 9, to keep the two bottles together and the user then twists the two bottles in the directions shown as 10 and 11. Because the diameter of the body of the bottle is much larger than that of the cap, additional torque can be generated using the same amount twisting forces due to the extra moment arm provided by the body of the bottle. Therefore, the cap of an invented bottle will be easy to open. Furthermore, the bottle will be easy to hold for a person with weak or injured wrist.

To close the cap tight, the user will firstly stack two bottles together with the cap of the bottom bottle already being loosely screwed on. The user will have the male pattern of the cap of the bottle at the bottom to engage with the female pattern on the bottom of the bottle at the top. The cap of the bottle at the bottom is the one to be tightened. Then the user applies some forces to keep the two bottles together and the user then twists the two bottles to tighten the cap.

Referring to FIGS. 4 and 5, the second variation of the invented easy-operated bottle, 12, is a bottle which cap, 13, has an outside shape resembles this of a nut, 15. On the bottom, 14, of the bottle is a recessed space, 16, which has similar cross-section shape of this of the cap and which can engage with a cap when the cap is inserted in the recessed space.

Referring to FIGS. 6 and 7, the third variation of the invented easy-operated bottle, 17, is a bottle which cap, 18, has a male pattern, 20, which consists of short plates extruding from the sides of the cap. On the bottom, 15, of the bottle is a recessed space, 21, which has similar cross-section shape of this of the cap and which can engage with a cap when the cap is inserted in the recessed space.

The uses of the second and the third variations of the invented easy-operated bottle are similar to aforementioned processes for the first variation and will not be repeated herein.

The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents, may be resorted to, falling within the scope of the invention as claimed.
