Definitions

• the present invention is related to containers.
• the present invention is related to containers having safety, leak-resistant and measuring features.
• US patent 4,134,513 describes a safety closure with at least one interlocking member which can only be removed by compressing the distal end of the sidewall straddling the interlocking member, together with the concurrent retrogressive movement of the closure.
• the container is described as having a cylindrical shape, with a pair of diametrically opposing and axially extending shoulders, which are adapted to interact with corresponding ribs on the closure.
• US patent 4,138,028 further discloses secondary interlocks for engagement when the closure is partially removed.
• a frictionally slidable, fluid-tight sealing arrangement is described, which is operative to prevent leakage of the container's contents.
• This sealing arrangement uses a continuous annular sealing head of flexible resilient material formed integrally on the interior surface of the sidewall of the closure.
• the sealing head slopes convergently, inwardly, and axially away from the closed endwall of the closure such that it will flex against and snugly contact the exterior surface of the mouth of the container to form a fluid-tight seal.
• the sealing head itself, however. may interfere with the insertion process when it approaches the mouth of the container. This is because the sealing head is sloping inwards, yet the mouth of the container needs to be inserted within this seal. As a result, the mouth of the container can easily be jammed onto the sealing head instead of sliding within it.
• the present invention provides a container having a hollow body for retaining liquid, and a dispensing end for pouring.
• the dispensing end has an exteriorly threaded cylindrical hollow neck portion extending from a shoulder.
• the cap is provided with a closed end wall and a cylindrical and internally threaded wall depending from the end wall. The thread on this wall is adapted to cooperate with the thread on the neck of the bottle to allow the cap to turn onto the neck to close the bottle.
• the cap is also provided with a spout which depends from the closed end wall of the cap and adapted for telescopic insertion into the neck of the bottle. This spout may act not only as a measuring and pouring structure, but also as a leak-resistant seal by having a thickened base which pushes the neck radially outwards upon closure of the cap.
• the bottle is preferably of molded plastic, with a locking member being molded onto the shoulder of the bottle.
• the cap is also provided with an external wall which depends integrally from the end wall and is adapted to form a sidewall over the neck.
• This external wall is provided with a ridge which is adapted to engage the locking member when the cap is closed, such that the cap is locked into the closed position. Unlocking can only be effected by squeezing the cap in a manner so as to release the ridge from the locking member.
• the external wall is made from a material which is deformable under pressure.
• the bottle has a non-cylindrical shape such that it would not roll off a table even if turned on its side.
• Figure 1A and B are the perspective elevated views of a bottle and a cap respectively according to the present invention.
• Figure 1C and D are the top and side views of the same bottle according to the present invention.
• Figure 2A to D are the top, front, back and side views respectively of the same cap.
• Figure 2E is the longitudinal cross-sectional view along line A-A of the same cap.
• Figure 3A is the top view of the closed bottle and cap.
• Figure 3B is the longitudinal cross-sectional view along line B-B of the closed bottle and cap.
• Figure 1A shows a bottle according to the present invention.
• the bottle has a non-cylindrical hollow body 20 and a dispensing end 22 having a shoulder 24 and a hollow neck 26.
• Neck 26 is provided with a threaded exterior.
• Optional measurement markings 30 are also provided to indicate the amount of liquid in the bottle and the amounts dispensed.
• a locking member 32 having the general shape of a saddle is provided on the shoulder.
• the bottle is tear drop- or pear-shaped with a rounded side 27 and a pointed side 29 such that the bottle would not roll off even if it is kept on its side.
• Figure 1 B shows a cap with a closed end wall 34 and an external wall 36 which is shaped to match the shape of the bottle, with a rounded side 37 and pointed side 39. Markings 38 are also provided to indicate the position in which a person has to squeeze in order to release the locking mechanism.
• Figure 1C shows a top view of the same bottle according to the present invention, showing clearly the saddle-shaped locking member 32 with two humps 33 and a valley 35.
• FIG. 2 shows the details of the cap, with the external wall 36 shaped into a tear drop having a rounded side 37 and a pointed side 39.
• Spout 42 is provided with an arched indentation 50 which matches the opening of the bottle. This indentation facilitates the pouring from the bottle into the spout.
• medicine may be poured and measured inside the spout by resting the opening of the bottle on the arched indentation.
• a protruding lip 48 is also provided on the other side of the spout to facilitate the pouring out of liquid measured inside spout 42. This lip is shaped like the tip of a spoon such that liquid may be poured out conveniently without dripping, and a child may drink directly from it.
• the spout may also be provided with markings to indicate volumes. These features on the spout provide a convenient and spoon-free medicine measuring and administering capability to the bottle ideal for use with all ages.
• a ridge 44 (preferably of solid plastic molded together with the cap) is provided at the end of the rounded side. The position of ridge 44 coincides with the position of the locking member on the bottle, such that when the cap is twisted firmly close, the ridge will be forced over the first hump of the saddle to settle into the valley. No further twisting movement of the cap is then possible under normal usage to prevent inadvertently opening of the bottle.
• Markings 38 are provided at two positions 90 degrees from ridge 44.
• FIG. 3 shows the interaction between the same cap and bottle according to the present invention.
• the threaded wall 40 has internal threads which are adapted to provide threaded engagement with bottle neck 26.
• Spout 42 is accurately position and provided with a thickened base such that it can slide telescopically within neck 26. As the cap is twisted close, the thickened base 52 forces the opening of the bottle outwards, resulting is a tight and leak-resistant seal.
• the bottle and cap may be fabricated from various materials, such as different kinds of plastics.
• the bottle is preferably blow molded from polyethylene and the cap molded from polypropylene.
• the diameter at the base of the spout should be slightly larger than the diameter of the opening at the neck of the bottle (e.g. OJmm), while the tip of the spout should be smaller than the neck and made of a deformable material. This allows the spout to be easily inserted into the neck, while forcing the neck into tight association with the thickened base when the bottle is tightly closed.
• non-cylindrical shapes may also be used based on the teaching herewith to design a bottle according to the present invention.
• the tear drop-shaped bottle presents a challenge in the design, as there is an inherent asymmetry along line C-C of Fig. 3A.
• the front is the pointed end and the back is the rounded end.
• the molten plastic material used for blow molding the bottle is preferably elliptical in shape.
• the center line of the air tube for blowing may be shifted forward (towards the pointed end) such that the locking saddle at the back (rounded end) is rendered stronger by a thicker layer of plastic.
