`ADDITIVE HOLDER FOR A PET BOTTLE
`BACKGROUND OF THE INVENTION
`1. Field of the Invention
`This invention is related to an additive holder for a PET 5
`bottle.
`2. Description of the Prior Art
`The convention PET bottle is designed for receiving a
`drink with a particular taste only and so it is impossible to
`adjust the taste thereby failing to meet everyone's appetite. 10
`Therefore, it is an object of the present invention to
`provide an additive holder for a PET bottle which enables an
`additive such as sugar, cream milk, or the like to mix with
`a drink in the PET bottle as desired.
`
`SUMMARY OF THE INVENTION
`This invention is related to an additive holder for a PET
`bottle.
`According to a preferred embodiment of the present
`invention, an additive holder for a PET bottle includes a
`tubular member having an open top formed with a flange and
`an open bottom formed with a toothed neck, the tubular
`member being fitted in the externally threaded mouth with
`the flange resting on an upper edge of the mouth, the tubular
`member having an inner side formed with a circular
`protrusion, a container having an upwardly extending handle 25
`and fitted inside the tubular member and kept in place by the
`circular protrusion, with the handle extending upwardly out
`of the tubular member, a locking cap provided with internal
`threaded engageable with the externally threaded mouth and
`having an axial through hole receiving the handle of the
`container, and a cover engageable with a top of the locking
`cap.
`It is the primary object of the present invention to provide
`an additive holder for a PET bottle which enables an additive
`such as sugar, cream milk, or the like to mix with a drink in
`a PET bottle as desired.
`It is another object of the present invention to provide an
`additive holder which can be easily mounted in in a PET
`bottle.
`It is still another object of the present invention to provide
`an additive holder for a PET bottle which is simple in
`construction.
`It is still another object of the present invention to provide
`an additive holder for a PET bottle which is fit for practical
`use.
`It is a further object of the present invention to provide an
`additive holder for a PET bottle which is low in cost.
`The foregoing objects and summary provide only a brief
`introduction to the present invention. To fully appreciate
`these and other objects of the present invention as well as the
`invention itself, all of which will become apparent to those
`skilled in the art, the following detailed description of the
`invention and the claims should be read in conjunction with
`the accompanying drawings. Throughout the specification
`and drawings identical reference numerals refer to identical
`or similar parts.
`Many other advantages and features of the present inven(cid:173)
`tion will become manifest to those versed in the art upon
`making reference to the detailed description and the accom(cid:173)
`panying sheets of drawings in which a preferred structural
`embodiment incorporating the principles of the present
`invention is shown by way of illustrative example.
`

`
`DETAILED DESCRIPTION OF THE
`PREFERRED EMBODIMENT
`For the purpose of promoting an understanding of the
`principles of the invention, reference will now be made to
`the embodiment illustrated in the drawings. Specific lan-
`15 guage will be used to describe same. It will, nevertheless, be
`understood that no limitation of the scope of the invention is
`thereby intended, such alterations and further modifications
`in the illustrated device, and such further applications of the
`principles of the invention as illustrated herein being con-
`20 templated as would normally occur to one skilled in the art
`to which the invention relates.
`With reference to the drawings and in particular to FIGS.
`1 and 2 thereof, the present invention generally comprises a
`cover 1, a locking cap 2, a container 3, and a tubular member
`4. The present invention is designed to be engaged with a
`PET bottle.
`As shown in FIGS. 1, 2 and 3 thereof, the tubular member
`4 has an open top formed with a flange 43 and an open
`bottom with a toothed neck 41. The bottom of the tubular
`30 member 4 is formed with an opening 42 enclosed by the
`toothed neck 41. The tubular member 4 is dimensioned so
`that the tubular member 4 can be fitted in the mouth 51 of
`a PET bottle 5 with the flange 43 of the former resting on the
`upper edge of the mouth 51. The inner side of the tubular
`member 4 is formed with a circular protrusion 44. The
`container 3 is a closed cylinder formed with a handle 31 at
`the top thereof. The container 3 is fitted inside the tubular
`member 4 with the handle 31 extending upwardly out of the
`tular member 4. The container 3 is kept in place by the
`40 circular protrusion 44 of the tubular member 4. The locking
`cap 2 is formed with internal threads (shown but not
`numbered) engageable with external threads 52 on the
`mouth 51 of the PET bottle 5. The top of the locking cap 2
`is formed with an axial through hole 21 for the passage of
`45 the handle 31 of the container 3. Further, the locking cap 2
`has a an upwardly extending circular flange 22 dimensioned
`to engage with the end cap 1.
`When in assembly, the tubular member 4 is first fitted
`inside the mouth 51 of the PET bottle 5 with the flange 43
`50 of the former resting on the upper edge of the mouth 51 of
`the PET bottle. Then, the containter 3 is pushed in the
`tubular member 4 with the handle 31 extending upwardly
`out of the tubular member 4 and kept in place by the circular
`protrusion 44. Thereafter, the locking nut 2 is turned on to
`55 the mouth 51 of the PET bottle with the handle 31 going
`through the axial through hole 21. Finally, the en cap 1 is
`snugly-fitted on the circular flange 22 at the top of the
`locking cap 2.
`Referring to FIGS. 4 and 5, when desired to mix the
`60 additive such as sugar, cream milk, or the like in the
`container 3 with the drink in the PET bottle 5, it is only
`necessary to remove the end cap 1 and then depress the
`handle 31 downwardly to have the bottom of the container
`3 pierced by the toothed neck 41 of the tubular member 4
`65 thereby causing the additive 30 in the container 3 to drop
`down into the PET bottle 5. The amount of additive added
`into the PET bottle 5 is related to the area pierced through

`by the toothed neck 41 and so can be controlled by the
`depressing force on the handle 31. Then, the locking cap 2
`is turned off to remove the tubular member 4 together with
`the container 3 to be served. The locking cap 2 may be
`turned on to the mouth 51 of the PET bottle and the end cap s
`1 may be engaged with the top of the locking cap to close
`the mouth 51 of the PET bottle.
`It will be understood that each of the elements described
`above, or two or more together may also find a useful
`application in other types of methods differing from the type 10
`described above.
`While certain novel features of this invention have been
`shown and described and are pointed out in the annexed
`claim, it is not intended to be limited to the details above,
`since it will be understood that various omissions, 15
`modifications, substitutions and changes in the forms and
`details of the device illustrated and in its operation can be
`made by those skilled in the art without departing in any way
`from the spirit of the present invention.
`Without further analysis, the foregoing will so fully reveal
`the gist of the present invention that others can, by applying
`current knowledge, readily adapt it for various applications
`without omitting features that, from the standpoint of prior
`art, fairly constitute essential characteristics of the generic or
`specific aspects of this invention.
