Abstract

A bottle with a narrowing bottleneck (figure 3) containing a thin folding dispenser (figures 4, 5, 6) which separates two substances inside the bottle until the bottle is opened causing the dispenser to fold downwards and mix the separated ingredients within the bottle. The bottle may be opened by a twist bottle lid (figure 1) which may be connected to the dispenser through a stem (figure 2). The stem could be connected to the lid by a friction-fit extruded insert in the lid, as shown in figures 1 & 7, and to the dispenser by a bump fit as shown in figure 8. The dispenser may be capable of being folded from a fully closed position (figure 4) to a fully open position (figure 6) by the concurrent action of the stem and the moulded lip. The dispenser may be made from plastic and could be disposable.

Description

Disposable shaker This invention separates two ingredients within a plastic bottle which are later ogether after tine dividing mechanism folds when opening the bottle.

The plastic bottle will contain a thin plastic dispensing mechanism within the bottle which will keep the two ingredients separate. The mechanism will be hinged into the mould of the bottle neck. When the lid is twisted open, the plastic dispensing mechanism is forced against the wall of the bottle which in turn makes it pop open and invert. As the bottle lid gets higher up the screw thread, the neck of the bottle, as this gets slimmer, forces the mechanism to cram in on itself, opening the folds. This releases one ingredient into the other. The lid can then be separated from the dispensing mechanism by pulling them apart and disposing of the mechanism before returning the lid and shaking.

The invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 shows the lid which is twisted open Figure 2 shows the removable plastic tube connecting the dispensing mechanism to the lid Figure 3 shows the moulded lip of the bottle neck Figure 4 shows the plastic dispensing mechanism while closed Figure 5 shows the plastic dispensing mechanism while opening Figure 6 shows the plastic dispensing mechanism completely open Figure 7 shows Friction Fit Location Extrusion in Bottle Lid Figure 8 shows Bump Fit on Plastic Connector Tube Figure 9 shows Neck of Dispensing Mechanism Figure 10 shows top view of the dispensing mechanism while closed Figure 1 shows the lid which is twisted to open the bottle, the lid ched to the plastic tube shown in Figure 2. Figure 7 shows the Friction Fit Location Extrusion which holds the plastic tribe (figure 2) on the lid (Figure 1).

The other end of the plastic tube shown in Figure 2 is connected to the plastic dispensing mechanism shown in Figure 4. The plastic tube (Figure 2) is attached to plastic dispensing mechanism (Figure by the Bump Fit which is shown in Figure 8.

The plastic dispensing mechanism in Figure 4 is placed on the moulded lips of the bottle shown in Figure 3.

When the lid (figure 1) is twisted, it willcause the plastic dispensing mechanism (figure 4) to transform to Figure 5, and then Figure 6.

These three figures (Figure 4, 5, 6) shows the three stages of the dispensing mechanism, from the closed position through to the open and dispensed positions. The mechanism is made from a thin plastic sheet that has folds and grooves that allow it to fold in on itself but also to open inside out with enough pressure, When the lid is twisted open, the plastic dispensing mechanism is forced against the wall of the bottle which in turn makes it pop open and invert. As the bottle lid gets higher up the screw thread, the neck of the bottle, as this gets slimmer, forces the mechanism to cram in on itself, opening the (Ads. This releases the ingredients from the top of the bottle to the bottom, and the two ingredients will be in contact.

The lid (Figure 1) can then be separated from the dispensing mechanism (Figure 6) by pulling them apart and disposing of the mechanism before returning the lid and shaking,
