DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A preferred embodiment of a multi-functional dispenser in the present invention includes a container body
3
, a pencil head holder
4
, a brush rod
44
and a top cover
5
as main component combined together.
The container body
3
is an interior hollow container for filling in a solvent such as finger enamel or correcting agent. The container body
3
is provided with a bottom base
31
at the bottom and male threads
30
around the outer circumferential edge of a mouth on top for the pencil head holder
4
to be threadably fitted therein. Further, the container body
3
is made of resilient soft material to be easily pressed with fingers.
The pencil head holder
4
is formed with female threads
40
around the bottom inner edge to engage threadably with the male threads
30
on top of the container body
3
. The pencil head holder
4
is formed inside with a hollow cavity
41
having its top end shrunken and provided with a solvent outlet tube
42
protruding out of the pencil head holder
4
, and a connect opening
43
formed at the bottom for receiving the brush rod
44
.
The brush rod
44
is provided on top with a hollow brush rod head
440
communicating with the hollow cavity
41
of the pencil head holder
4
. Then, one or more solvent guiding holes
441
are bored on the brush rod
44
adjacent to the hollow brush rod head
440
to let the solvent get into the hollow brush rod head
440
and filled up the hollow cavity
41
of the pencil head holder
4
through these solvent guiding holes
441
. Thus, a proper amount of solvent can be squeezed out through the solvent outlet tube
42
when the container body
3
is pressed. Besides, a brush hair
45
is fixed at the bottom of the brush rod
44
for smearing.
The top cover
5
for covering up the upper portion of the pencil head holder
4
, as shown in
FIG. 5
, is formed with a stuffing member
51
on the inner top to let the solvent outlet tube
42
of the pencil head holder
4
completely sealed in this stuffing member
51
to prevent the solvent from seeping out when the top cover
5
is covered around the pencil head holder
4
.
The feature of the invention is that the hollow brush rod head
440
of the brush rod
44
has its out circumferential edge formed into a projecting rim
442
, and the hollow cavity
41
of the pencil head holder
4
has its bottom connect opening
43
bored with an engage groove
430
to correspond to the projecting rim
442
so as to permit the brush rod
44
and the pencil head holder
4
to engage with each other directly.
Specifically, the brush rod
44
and the pencil head holder
4
are combined together by the engagement of the projecting rim
442
and the engage groove
430
so the brush rod
44
can easily be disengaged from the connect opening
43
of the brush head holder
4
for cleaning in case the solvent outlet tube
42
of the pencil head holder
4
or the hollow brush rod head
440
of the brush rod
44
is blocked. Besides, the projecting rim
442
and the engage groove
430
are impossible to be damaged in using, because they are made of flexible material. After cleaning, simply press the brush rod
44
to be fitted in the connect opening
43
of the pencil head holder
4
to let the projecting rim
442
of the hollow brush rod head
440
meshed with the engage groove
430
of the connect opening
43
.
The solvent outlet tube
42
and the pencil head holder
4
are made integral, so the solvent outlet tube
42
cannot slide or move biasly, as shown in FIG.
6
. If a user carries on painting with an excessive force (over 1.5 kg), the solvent outlet tube
42
will sink in the pencil head holder
4
to prevent damage to the surface of a finger nail, ensuring safety in painting finger nails, lowering producing time and cost due to comparatively few components and simple producing processes, and heightening competitive force of products.
Furthermore, as shown in
FIG. 7
, the intermediate circumferential portion of the pencil head holder
4
for engaging the top cover
5
is formed with toothed rings
46
, and the top cover
5
has its inner circumferential wall formed with one or more engage teeth
52
matching with the toothed rings
46
and respectively having one or more teeth.
When the top cover
5
is mounted around the pencil head holder
4
, the engage teeth
52
of the top cover
5
can easily mesh with the toothed rings
46
of the pencil head holder
4
. Thus, when the top cover
5
is fitted with and turned around the pencil head holder
4
, the pencil head holder
4
can synchronously be screwed in or out along the male threads
30
of the container body
3
for facilitating using the brush hair
45
.
In using, as shown in
FIG. 8
, when the container body
3
is filled up with finger enamel to be used for painting, just pull up the top cover
5
and press the container body
3
with fingers to let the solvent flow into the hollow cavity
41
of the pencil head holder
4
through the solvent guiding hole
43
and then get it out for use through the solvent outlet tube
42
. When the brush hair
45
is to be used for smearing the surface of finger nails, only let the top cover
5
fitted around the pencil head holder
4
and then directly turned around to let its engage teeth
52
meshed with the tooth rings
46
of the pencil head holder
4
, and thus the pencil head holder
4
is synchronously turned around and disengaged from the container body
3
to let the brush hair
45
ready for use.
As can be noted from the above description, the invention has the following advantages.
1. Having high practicability. The brush rod and the pencil head holder are combined together by meshing the projecting rim with the engage groove so the brush rod is easy to be disengaged from the pencil head holder for cleaning. Besides, the projecting rim of the brush rod and the engage groove of the pencil head holder are made of fixable material, so they will not be damaged in using. After cleaning, the brush rod is directly pressed and inserted in the connect opening of the pencil head holder to let the projecting rim fitted with the engage groove, thus, facilitating assembling and disassembling.
2. Economizing producing cost. The solvent outlet tube and the pencil head holder are formed integral, not only preventing the solvent outlet tube from sliding or moving biasly to ensure safety in using, but also greatly lowering producing time and cost due to comparatively few components and simple producing and assembling processes, and heightening competitive force of products.
3. Having extensive adaptability: The container body can be filled with finger enamel solvent for painting finger nails or filled with correcting agent for correcting words.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
