2. Description of the Related Art
Text is the greatest mankind's invention ever that allows human civilization to be developed rapidly. In the meantime, various different pens were invented for writing text, but writing a wrong text may cause misunderstanding, so that text correction apparatuses such as erasers, correction liquids and correction tapes are also well developed as pens advance.
The correction liquid is a white opaque pigment coated on a correction surface to cover the wrong text. After the correction liquid is dried, the correct text can be written on top of the dried correction liquid. At present, the correction liquids available in the market come with different using methods according to the different containers. For example, a container with a cap is provided for containing a correction liquid, and the cap has a brush formed thereon, and the cap is normally tighten to seal the container and prevent the correction liquid from being dried and keep the brush to be dipped in the correction liquid. When use, the cap is removed, and the brush is used to coat the correction liquid onto a correcting surface. However, there is a drawback that users have to put the brush into the container repeatedly and the container may be overturned easily.
To overcome the aforementioned drawback, a pen-shaped or can-shaped correction liquid is introduced to facilitate users to hold and use the text correction apparatus, and the correction liquid is contained in a pen-shaped container (U.S. D648798) or a flat polygonal can-shaped container (U.S. D456844) corresponding the shape of a user's hand, and a specially designed liquid output nozzle is installed at an open end of the can container. A pressure is produced when the can container is extruded or pressed, so that the can container produces a lateral deformation to output the correction liquid from the liquid output nozzle in order to coat the correction liquid onto a correcting surface for a text correction. Although the apparatus can be used continuously to improve the convenience of use, users have to apply a force downward to abut the liquid output nozzle against the correcting surface in an actual operation, and apply a lateral compression on the can container to produce a partial deformation for outputting the correction liquid. Since the force applying directions are different, the operation does not go smoothly. In addition, the can container has a relatively small deformation, so that the correction liquid may not be squeezed out easily, particularly in cold and humid countries.
It is a primary objective of the present invention to provide a palm-pressing text correction apparatus manufactured according to the shape of a user's hand, so that the user can hold the apparatus within the user's palm operating range and change the deformation of an elastic container precisely by the pressing force produced by holding the apparatus. Since the deformation is large, therefore the operation is more intuitive, convenient and effort-saving. In addition, the separate design of the elastic container and the casing facilitates replacement, repair and maintenance and avoid unnecessary waste of materials to comply with the environmental protection requirements.
To achieve the aforementioned objectives, the present invention provides a palm-pressing text correction apparatus, comprising: a casing, having a first opening and a second opening formed at both ends of the casing respectively; an elastic container, mounted into the casing, and having the correction liquid filled in the elastic container, a liquid output nozzle disposed at an end of the elastic container, and a pressed end formed at the other end of the elastic container, so that the liquid output nozzle is protruded out from the first opening; and a pressing element, coupled to the pressed end, for producing an axial force by a pressing force and applying the axial force to the pressing element to compress and deform the elastic container in an axial direction parallel to the liquid output nozzle to output the correction liquid, so that the correction liquid can flow out from the liquid output nozzle to perform a text correction.
In a preferred embodiment, the casing is comprised of a front casing and a rear casing, and the first opening is disposed at an end of the front casing, and the other end of the front casing is integrated with an end of the rear casing, and the second opening is disposed at the other end of the rear casing and provided for covering the elastic container therein.
In addition, the elastic container and the pressing element can be connected by the following methods: 1. The pressed end of the elastic container has an outer thread, and the pressing element contains an inner thread formed therein and corresponding to the outer thread for screwing and coupling the pressing element to the elastic container. 2. The pressing element has a push rod installed therein and corresponding to the pressed end, so that the push rod normally abuts and connects the elastic container.
The palm-pressing text correction apparatus further comprises a plurality of bumps formed between an internal wall of an opening of the pressing element and an external wall of the second opening for reducing the gap between the pressing element and the casing to improve the stability of the motion. In addition, the bumps will not have too much contact with the external wall of the casing, so that the friction of the relative motion can be reduced to make the motion more smoothly.
The palm-pressing text correction apparatus further comprises a plurality of wrinkles formed at the middle section of the elastic container and disposed with an interval apart from each other, and when the wrinkles are compressed by an axial force, the intervals of the wrinkles are stacked together, and after the axial force is released, a resilience restores the wrinkles to their original positions.
The technical content of the present invention will become apparent with the detailed description of preferred embodiments and the illustration of related drawings as follows.
With reference to
The casing 11 is a circular tubular structure made of a hard plastic material, and having a first opening 111 and a second opening 112 formed at both ends of the casing 11 respectively, and the second opening 112 is disposed on the axis of the first opening 111.
The elastic container 12 is fixed into the casing 11 by screwing and provided for filling a correction liquid 2, and a liquid output nozzle 121 is disposed at an end of the elastic container 12, and a pressed end 122 is formed correspondingly at the other end of the elastic container 12, and the liquid output nozzle 121 is protruded out from the first opening 111. The elastic container 12 has a plurality of wrinkles 123 formed at the middle section of the elastic container 12 and disposed with an interval apart from each other to form a reciprocating telescopic lantern structure. When the wrinkles 123 are compressed by an axial force, the intervals of the wrinkles 123 are stacked and shortened. After the axial force is released, the resilience restores the original positions of the wrinkles 123. In this preferred embodiment, an outer thread 1221 is formed at the exterior of the pressed end 122.
The pressing element 13 includes an inner thread 131 formed inside the pressing element 13 and corresponding to the outer thread 1221, and the pressing element 13 is coupled to the pressed end 122 by screwing. In addition, a plurality of bumps 14 is formed between an internal wall of the opening of the pressing element 13 and an external wall of the second opening 112 for reducing the friction produced in the relative motion and improving the stability of the relative motion.
It is noteworthy that the shape and length of the present invention are designed according to the shape of a user's hand. In particular, the length falls within a range of 5 cm-10 cm to facilitate users to hold the apparatus and operate the apparatus within the operating range of the user's palm. Therefore, an axial force is created by a pressing force when the user holds the apparatus, and the axial force applied to the pressing element 13 compresses the elastic container 12 to deform in the axial direction of the liquid output nozzle 121, so that the liquid output nozzle 121 can abut a correcting surface and allow the correction liquid to flow out to perform text correction. Since the axial force causing deformation of the elastic container 12 is created naturally when the user holds the text correction apparatus in his/her hand, it is effortless to use the text correction apparatus according to the present invention. And a precise quantity of outputted correction liquid can be controlled easily to provide a very convenient and intuitive application.
