Abstract

A dispensing closure device (10) is provided having an overcap (30) comprising a base (40) and a cap (45) attached or attachable to the base. The base is connectable to the container (20). The closure device also includes a cover member (35) with which the overcap can interface to at least partially define the contour of the closure device.

Description

dispensing capping device

The present invention relates generally to a closure and more particularly to a dispensing closure for a container.

The construction of dispensing capping devices is often a consideration of conflicting requirements. For example, the ability to be produced in high volumes by molding may place certain constraints on the shape of the closure device or the function it can perform.

The present invention seeks to provide increased product design flexibility while maintaining functionality and manufacturing efficiency.

According to a first aspect of the present invention there is provided a dispensing closure device having an overcap comprising a base and a cover attached to the base by a hinge, The base is connectable to a container, the closure means further comprising a cover part, the top cap is capable of abutment with the cover part to define at least a partial contour of the closure means, characterized in that the cover part comprises a notch , a portion of the hinge is movable into the notch.

The top cap can be formed as a single piece. For example, the top cap may be formed from a base integrally formed with a cover.

The profile of the cover part can be matched to the container to which the closure device is to be attached. In this way, there are fewer restrictions on the shape of the top hat.

The cover part may be formed as a skirt, for example a substantially cylindrical body with a circular portion or an oval portion.

The profile of the capping device may comprise or have an inverted taper.

The base may include a dispensing nozzle, which may be integrally formed.

The cover member may include an opening for receiving the top hat. The closure device can be assembled by docking the top cap into the cover part, eg by lowering the top cap in from above or by pushing the top cap upwards from below.

The closure device may be constructed in two parts, eg a one-piece top can and a one-piece hood.

The cover part includes a notch into which a portion of the hinge is movable. The cover part therefore does not interfere with the opening and closing of the top cap.

The shroud component may include a curved container boundary line and a top cap boundary line, the lines being substantially parallel to each other.

The present invention is now more specifically described by way of example with reference to the accompanying drawings, in which:

Figure 17 is a portion of a capping device formed in accordance with an alternative embodiment.

Referring first to FIG. 1 , there is shown a dispensing closure device, generally indicated at 10 , shown attached to a container 20 .

Also referring to FIGS. 2-15 , the capping device 10 includes a top cap 30 and a cover member 35 .

The overcap 30 includes a base 40 and a cover 45 .

The base includes a generally arcuate top deck 50 in which a dispensing nozzle 55 surrounded by a channel 56 is formed. An annular outer skirt 60 depends from the top deck 50 and includes a pair of diametrically opposed U-shaped cutouts 61 . The interior of the annular outer skirt 60 carries a retaining flange 62 at its free end. The flange 62 does not extend across the cutout 61 . An annular inner skirt 65 depends from the top deck 50 radially inwardly of the annular outer skirt 60 .

The cover 45 includes a top plate 70 having a shape corresponding to the top deck 50 . An annular sealing skirt 71 depends from top plate 70 . The top plate 70 is also provided with a perimeter curved side wall 72 having a central apex 73 .

The base 50 and cover 45 have respective linear rear sides 46 , 51 . The rear sides 46, 51 are joined together by a hinge assembly consisting of two fixed outer hinge elements 47, 52 and a central movable hinge element 53, said outer hinge elements 47, 52 being carried on blocks 48, 49 superior. Elements 46, 51 are fixed living hinges. Element 53 is a generally L-shaped rigid link connected to the lid and base by membrane hinges 54A, 54B, respectively.

The cover part 35 comprises a generally cylindrical body having an oval side wall 36 which is mostly open except for a rear deck 37 which carries a recess 38 comprising a groove The purpose of the port 39, notch 39, will be described in more detail below. In section D, the majority of sidewall 36 is substantially linear, except for the "rear" in the area of deck 37 which is curved and flared.

In this embodiment, the top cap 30 is formed as a single piece, the base and lid are integrally formed, and the cover member 35 is formed as a separate single piece. The top cap 30 is shaped to be received within the opening defined by the shroud sidewall 36 . The top cap 30 is received within the cover part 35 such that the hinge blocks 48 , 49 snap into the recesses 38 . The perimeter of the base top deck 50 also fits snugly into the side walls 36 . These component structures are hidden in the capping device.

Once assembled, the closure device 10 may be applied to the container 20 . The closure device 10 is applied such that the annular outer skirt 60 fits around the container neck 21 and the inner skirt 65 is pushed into the hole in the neck 21 . Figure 16 shows this in more detail, with the cover part 35 removed for clarity. The retaining flanges 62 of the annular outer skirt 60 snap fit under corresponding retaining flanges 22 provided on the neck 21 to hold the closure device 10 securely in place. It should be noted that in this embodiment the cover member 35 plays no role in retaining the capping means for the container, but rests in the channel 23 on the neck shoulder 24 of the container.

In use, the closure means is opened and closed by flipping the cover 45 relative to the base 50 . As best shown in FIGS. 14 and 15 , the hinge member 53 moves rearwardly into the notch 39 when the lid 45 is flipped from the closed position to the open position.

In the closed position, the cover 45 is fitted onto the base 40 . The sealing skirt 71 fits around the nozzle 55 and fits into the channel 56 . The roof deck 70 and thus the side walls are slightly larger than the base deck so that the free ends of the side walls 72 fit around the perimeter of the deck.

Since the cover part 35 in this embodiment does not carry any working parts in this way, its shape is not limited by conventional manufacturing techniques. Furthermore, all the parts that need to interact with each other when the closure device is closed are located on the same part, which allows good control.

Contour matching can be more easily achieved because the cover part can match the contour of the associated container. For example, the curvature of sidewall 36 can be easily matched to continue the curve from container 20, as shown in FIG. 1 . In addition, the parting line between the top cap and the base is curved, and at least a portion of its curvature can be replicated to the free end of the cover member 35 so that the boundary line 75 between the cover member and the container 20 can be matched, in this case At least a portion of the middle is parallel to the boundary line between the top hat and the cover part (which in this embodiment is also the parting line).

Figure 17 shows a capping device 110 formed in accordance with an alternative embodiment.

Capping device 110 is very similar to capping device 10 . The main differences include the shape of the orifice, the angle of recirculation, the general formation of the snap-fit structure, and the sealing structure. The outlines of the two separate parts, the assembled parts, and the overall mechanism of the assembly are substantially the same (although these may differ in other embodiments).

In Figure 17, the following features are marked:

1. Liquid backflow angle

2. Maintain structure

3. Snap ring groove

4. Hole sealing structure

5. Interlocking grooves

6. Nozzle shape

7. Sealing structure

In this embodiment, the capping device is designed and adapted for use in household/laundry applications. Other embodiments may be suitable for different purposes.

While the exemplary embodiments of the present invention have been described in detail herein with reference to the accompanying drawings, it should be understood that the invention is not limited to the exact embodiments shown, without departing from the appended claims and their equivalents. Various changes and modifications may be practiced herein without departing from the scope of the present invention.
