The web preferably extends between the outermost surface of the cup and the inner surface of the lower annular portion, wherein in use, the lower annular portion, cup and web assembly provide a fluid-tight means prior to first use of the cup. It will be appreciated that when the closure is placed on a container the fluid-tight means prevents access to the product contained within the container. To gain access the frangible web has to be broken. It will also be appreciated that the frangible web as described above and the frangible nibs described above both provide tamper evident means and tamper prevention means.

According to a third aspect of the present invention there is provided a method of moulding a closure as defined by the aforementioned second aspect wherein the closure is formed as a one-piece moulding.

Preferably the method is an injection moulding process.

By way of example only, embodiments of the present invention will now be described with reference to the accompanying drawings, in which: Figure 1 shows a plan view of a closure. comprising an integral dispensing spoon and illustrating the cap in an open state in accordance with the present invention; Figure 2 shows a cross-section of the closure, through AA; Figure 3 shows the cross-section of the closure, illustrating the cap in a closed state; Figure 4 shows a plan view of a second embodiment of the present invention illustrating the cap in an open state and comprising a cup dispenser ; Figure 5 shows a cross-section of the embodiment through BB, Figure 6 shows the cross-section of the embodiment illustrating the cap in a closed state and the dispensing device shown in the stored position, Figure 7 shows a plan view of a third embodiment of the present invention illustrating a container comprising a closure and illustrating the cap in an open state, Figure 8 shows a cross-section of the third embodiment through CC; and Figure 9 shows the cross-section of the third embodiment illustrating the cap in a closed state and the dispensing device shown in the stored position.

With reference to Figures 1 to 3, the closure 1 illustrated is injection moulded from a suitable plastics material and comprises an upper elliptical cap 2 and a lower elliptical annular portion 4. The upper cap 2 is joined to the annular portion 4 by a hinge means 6. The elliptical cap 2 is formed with two circumferential wall sections 8,10 extending from a substantially disc-like upper section 12. The two wall sections 8 and 10 are substantially parallel and define an elliptical channel 14. Extending from the inner surface of the upper section 12 is a tubular retaining spigot 16.

The hinge means 6 which joins the cap 2 to the annular portion 4 comprises a rectangular section 18 disposed between two parallel weakened groove lines of attachment 20 whereby the cap 2 can be orientated between the open position shown in Figures I and 2 and the closed position shown in Figure 3.

The lower elliptical annular portion 4 comprises an outermost annular collar 22 and a radially inner annular collar 24. The collars 22 and 24 are radially spaced by an upper rim 26. Disposed within the annular portion 4 is a spoon 28. The spoon 28 is frangibly attached to the inner collar 24 by four frangible nibs 30. The spoon 28 comprises a measuring bowl portion 32 and a handle 34. Formed within the handle 34 is an aperture 35 extending therethrough and bounded by two wall sections 36 locally projecting inward and having a curved portion adapted to co-operate with the outermost surface of the retaining spigot 16.

The closure 1 is injection moulded in one piece in the form shown in Figures 1 and 2. The closure can be fitted onto a container (not shown).

The container neck is located within the annular region 38 defined by the annular collars 22,24 and the upper rim 26. The cap 2 is placed on top of the lower portion 4, the upper rim 26 being disposed within the elliptical channel 14, the arrangement being such that the cap 2 and the lower portion 4 provide a snap-engagement.

When the container (not shown) and cap arrangement is first used, the cap 2 will be removed from the lower portion 4. The user will remove the spoon 28 by placing a number of digits into the lower portion 4 either side of the handle 34 and parting the spoon 28 from the portion 4 by breaking the nibs 30. The spoon 28 may then be used to dispense the contents of the container. After use the spoon 28 is retained within the cap 2 by placing the bore 35 over the spigot 16 such that the opposing sections 36 frictionally engage the said spigot and hold the spoon thereon. The spoon can be repeatedly retained on the spigot 16.

Referring to Figures 4,5 and 6, this embodiment is substantially the same as that described with reference to Figures 1,2 and 3 of the accompanying drawings and therefore similar numerals have been used to indicate similar components and further description will not be given. However, with this particular embodiment the closure has a circular cross-section and the dispensing means is in the form of a measuring cup 40 disposed within the lower portion 4 and being held therein by four frangible nibs 30. The cap 2 is formed with four lugs 42 extending radially inwardly from the innermost surface of the wall section 10. The lugs 42 are circumferentially equally spaced around the wall section 10.

In this embodiment, after the cup 40 has been removed from the lower portion 4 by fracturing the nibs 30 and used to dispense the product within the container, it is retained within the cap 2 by the frictional contact of the radially outermost surface of the cup 40 and the lugs 42.

The cup 40 can be formed with measuring indication means in the form of a unit scale formed on the cup wall.

It will be appreciated that the components of the closure can be moulded individually as well as an integral one-piece arrangement. When the closure comprises separate cap 2 and lower portion 4, the cap 23 can be secured to the lower portion 4 by a screw thread or any similar means.

Referring to Figures 7,8 and 9, this embodiment is substantially the same as that described with reference to Figures 1,2 and 3 of the accompanying drawings and therefore similar numerals have been used to indicate similar components and further description will not be given. However, with this particular embodiment the radially outermost wall 52 of the closure 50 extends downwardly from the upper rim 26 substantially beyond the lowermost end of the inner annular collar 24. A circular disc base 54 is disposed within the circular open end of the wall 52 so defining an enclose space 56. The radially outermost surface of the disc is in frictional contact with the radially innermost surface of the wall 52.

The cup 40 is held within the lower portion 4 by a circumferential frangible web 58 extending between the outermost radial surface of the cup and the innermost radial surface of the inner annular collar 24.

The closure 50 can be injection moulded in two parts ; one part comprising the closure and the other part comprising the circular disc base 54.

The container is filled with product by first inverting the closure and then placing the product into the space 56. The product may be in any form such as a liquid, powder or capsule form. The product is contained in the inverted closure. The frangible web 58 forms a fluid-tight membrane between the cup 40 and the inner wall 24. After the closure has been filled with the product, the base 54 is then placed within the space 56 and appropriately fixed to the closure, such that the only access to the product within the container is by breaking the frangible web 58.
