Dispensing apparatus

Abstract

A spout and opener includes an opener portion with a sharp tip for opening a pack. The opener portion gets thicker and thicker from the sharp tip in order to fit into the pack tighter and tighter. The spout receives liquid from the pack. The spout portion directs the liquid to the exterior of the pack from the opener portion. The stop extends between the spout portion and the opener portion for avoiding insertion of the whole spout and opener into the pack.

Description

FIELD OF INVENTION

The present invention relates to a beverage pack and, more particularly, to a dispensing apparatus for a beverage pack.

BACKGROUND OF INVENTION

Beverage is contained in various containers such as bottles, cans and packs. Such a pack is typically made of a laminate. The laminate includes a paperboard and an aluminum foil coated on the paperboard.

In a design, no weak point is provided in the pack. A corner must be cut from the pack so as to define an orifice through which drink can be poured. A pair of scissors or a knife is necessary for getting drink from the pack.

In another design, an orifice is punched in the paperboard during production of the pack. A straw with a sharp point is inserted through the orifice in order to pierce the aluminum foil. Thus, drink can be sucked from the pack through the straw. However, this design is not convenient for two persons wanting to share a beverage pack.

U.S. Pat. No. 54,7370 discloses a detachable spout and can opener including a hollow body B with a sharp point d. The body B includes four walls a. Above a line 1—1, the walls a are constantly wide. Below the line 1—1, the walls a converge to the sharp point d. A ridge f is formed on each wall a. An opening g is defined in each wall a. A pack can be pierced by means of the sharp point d. Beverage can flow through the openings g. Complete opener portion of the body B into the pack is prevented by means of the ribs f. However, the body B tends to slack and fall from the pack since the walls a are equally wide above the line 1—1. The body B can be closed by means of a cap (not numbered). Once removed from the body B, the cap can be lost easily since it is an independent element.

The applicant's co-pending U.S. patent application Ser. No. 10/287649 filed on Nov. 5, 2002 discloses a dispensing apparatus. The dispensing apparatus cannot keep beverage in a pack once it is inserted into the pack.

The applicant's co-pending U.S. patent application Ser. No. 10/449401 filed on Jun. 2, 2003 discloses a dispensing apparatus including a spout and opener 10 and a cover 30 pivotally connected with the spout and opener 10. The spout and opener 10 can be closed by means of the cover 30.

The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.

SUMMARY OF INVENTION

According to the present invention, a spout and opener includes an opener portion with a sharp tip for opening a pack. The opener portion gets thicker and thicker from the sharp tip in order to fit into the pack tighter and tighter. The spout receives liquid from the pack. The spout portion directs the liquid to the exterior of the pack from the opener portion. The stop extends between the spout portion and the opener portion for avoiding insertion of the whole spout and opener into the pack.

The primary advantage of the dispensing apparatus of the present invention is the opener portion getting thicker from the sharp tip in order to fit tighter into the pack.

Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the attached drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

FIGS. 1˜4 show a dispensing apparatus according to the preferred embodiment of the present invention. Referring to FIG. 1, the dispensing apparatus includes a spout and opener 10, a cap 20 and a cover 30.

Referring to FIG. 2, the spout and opener 10 defines a passage 14. The spout and opener 10 includes a spout portion 11, an opener portion 12 and a stop 13 between the spout portion 11 and the opener portion 12. A cutout 15 is defined in an edge of the opener portion 12. A slot 16 is defined in the opener portion 12. A ridge 17 is formed on the spout portion 11. Two recesses 18 are defined in the spout portion 11. A slot 19 is defined in the stop 13.

The cap 20 defines an aperture 21 through which a ring (not shown) can be inserted. Thus, the dispensing apparatus can be hung on a proper external article. The cap 20 includes a tab 22 extending from an edge thereof. The tab 22 is inserted into the slot 19 when the cap 20 covers the opener portion 12.

The cover 30 is pivotally attached to the spout portion 11. The cover 30 includes two ears 31 formed thereon, a boss 32 formed on each of the ears 31 and a hook 33 formed thereon.

Referring to FIG. 3, the bosses 18 are put in the recesses 32. Referring to FIG. 4, the cover 30 can thus be pivoted between a covering position and an opening position on the spout portion 11. In the covering position of the cover 30, the buck 33 holds on to the spout portion 11.

Referring to FIG. 5, the opener portion 12 becomes thicker from a sharp tip 25 to the stop 13. When the opener portion 12 is inserted in a pack 40 (FIGS. 6 and 7), the increasing dimension of the opener portion 12 makes the opener portion 12 fit tighter in the pack 40. The stop 13 can abut against the pack 40 in order to prevent insertion of the whole spout and opener 10 into the pack 40.

Referring to FIG. 8, the opener portion 12 is tightly inserted in the pack 40. The cover 30 is in the covering position. Thus, beverage is kept in the pack 40.

Referring to FIG. 9, the cover 30 is in the covering position. The pack 40 is tilted so that the beverage is poured into a cup 41 from the pack 40 through the spout and opener 10.

Referring to FIG. 10, as only a small amount of the beverage is left in the pack 40, the pack 40 is turned upside down so that the last amount of the beverage is poured into another cup 42 from the pack 40 through the spout and opener 10. At this instant, the last amount of the beverage flows through the slot 16.

The present invention has been described via detailed illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention as defined in the claims.
