Abstract
The container (11) has a cylindrical neck and the cap (40) has a skirt screw-engaged on the neck. The skirt has a flared portion defining an elliptical shape in cross-section, which is resiliently deformable. The skirt has an aperture (42) at its shortest diameter and the neck has a projection (20) which snaps into the aperture to prevent unscrewing of the cap. Deformation of the skirt by squeezing releases the projection from the aperture to permit unscrewing. The container has a shoulder (13) with an elongate cross-section and the elliptical form of the flared part of the skirt is such that the skirt is flush with the elongate sides of the shoulder. <IMAGE>
Description
CONTAINER AND CAP ASSEMBLY AND CAP THEREFOR
This invention relates to a container and cap assembly, and a cap therefor, of the type known as a child-resistant container.
Containers of this type have interlocking means between the cap and the container to inhibit removal of the cap. The interlocking means can be over-ridden by an adult, but is designed to be difficult for a young child to over-ride. Many different designs of caps for this purpose have been made and among these it is known to provide a resiliently deformable cap skirt whereby the skirt can be squeezed to release the interlocking means.
Containers are currently in substantial use which are of elongate cross-section like an elongated ellipse.
These containers have a cylindrical neck, with an external screw-thread, centrally located on a shoulder and the cap therefor has an external diameter substantially equal to the external width of the shoulder at a position adjacent thereto.
It is desirable to provide a container and cap assembly of this type with interlocking means to render it child resistant. Difficulties have been encountered in providing such a child-resistant assembly in which the cap is flush with the shoulder at its narrow side and the present invention overcomes this problem.
The present invention provides a container and cap assembly wherein the container has a neck and the cap has a top from which depends a skirt engageable on the neck by relative rotary motion, the neck and skirt having interlocking means which resist rotary disengagement of the cap from the neck, the skirt being resiliently deformable to disengage the interlocking means, and wherein the interlocking means comprises a projection on the neck and an apertured portion of the skirt.
The skirt preferably has a flared part provided with the apertured portion, the flared part being of generally elliptical cross-section with the apertured portion adjacent the shortest diameter thereof.
The thickness of the skirt may be reduced in the region of the shortest diameter relative to the thickness in the region of the longest diameter.
The projection preferably has a wall at one circumferential side for engaging an edge of the aperture to inhibit said rotary disengagement, and a ramp surface at the opposite circumferential side to facilitate rotary movement in the engaging direction.
The -top is preferably provided internally with a resilient formation sealingly engageable with the neck.
The invention may also reside in a cap constructed in the manner defined above.
The invention may reside in a container and cap assembly wherein the container has a cylindrical neck centrally located on a shoulder of a body portion, wherein the body portion has an elongate cross-section in planes perpendicular to the neck axis, the elongate cross-section having radiussed corners, and wherein the cap has a skirt including a top, a cylindrical part and a flared part, the cylindrical part being internally adapted to be screw engageable with the exterior of said neck, the top being provided with resilient means sealingly engageable with the neck, and the flared part having, at the end remote from the top, a generally elliptical cross-section, the external smaller diameter thereof being substantially equal to the external width of the body portion at a position adjacent the neck and being adjacent thereto in the fully engaged position of the cap, the neck having a projection which engages in an apertured portion of the skirt in said fully engaged position to inhibit disengagement of the cap from the container, and the flared portion being resiliently deformable to release the projection from the aperture.
Reference is now made to the accompanying drawings, wherein Figure 1 is a perspective view of a container and cap assembly according to the invention;
Figure 2 is a perspective view of the container with the cap removed;
Figure 3 is a plan view of the cap; and
Figure 4 is a cross-section of the cap with the left side taken on line A--A of Figure 3 and the right side taken on line B--B of Figure 3.
Referring to Figure 1, there is shown a container 11 having a body 12 provided with a shoulder 13. The container is of elongated elliptical cross-section so as to have nearly flat sides 14. A cap 40 is engaged on the container and has an elliptical cross-section adjacent the shoulder 13 on which it is centrally located. The longer sides 41 of the ellipse of the cap are adjacent to the nearly flat sides 14 of the container body and are flush therewith.
Referring to Figure 2, the container includes a cylindrical neck 15 centrally located on the shoulder 13.
The neck has an externally screw-threaded portion 16 with a portion 1; of larger diameter adjacent the shoulder and defining an annular face 18. The larger diameter portion has a projection 20 adjacent one of the nearly flat faces 14 of the body. As shown, the left circumferential side of the projection has a substantially radial wall 21 and the opposite circumferential side is a ramp surface 22.
As shown in Figure 1, the projection engages in an aperture 42 in the cap 40 in the fully engaged position of the cap on the container.
The cap 40 has a top 44 and a skirt 45 (Figure 4).
The skirt has a cylindrical portion 46 adjacent the top and a flared portion 47. The cylindrical portion 46 has an internal screw thread 48 for engagement with the screw-threaded neck 15. The top 44 has an internal annular sealing ring 50 projecting therefrom. The ring being- deformable and being sealingly engageable with the internal lip of the neck 15.
A shoulder 51 is defined between the cylindrical portion 46 and the flared portion 47 and this shoulder is engageable with the annular face 18 on the neck to define the fully closed position of the cap on the container.
The ~flared portion 47 is elliptical, as previously described and the short diameter sides 52 of the flared portion are co-extensive with the adjacent cylindrical portion 46 and of constant diameter. The longer diameter sides 53 are flared relative to the cylindrical portion 46.
One of the shorter diameter sides 52 is provided with the aperture 42, which is complementary to the projection 20 on the neck 15.
The cap is moulded from plastics material so that the flared portion is resiliently deformable. The shorter diameter sides 52 may be of reduced diameter relative to the longer diameter sides 53 to facilitate deformation in the region of the aperture 42.
In use, the cap is screwed on the neck in conventional manner until the annular face 18 is engaged.
The flared portion is deformed as the cap is tightened, with the inner wall running on the ramp surface 22 of the projection. When the projection coincides with the aperture, the projection snap-engages into engagement therein.
The cap cannot be unscrewed from the neck unless the long diameter sides 53 are squeezed to deform the flared portion 47 and release the projection from the aperture, this squeezing being maintained during initial unscrewing of the cap. Unscrewing of the cap is otherwise inhibited by engagement of the radial wall 21 with an edge of the aperture.
The resilience of the flared portion is designed to make it difficult for a child to be able to exert sufficient pressure to maintain the necessary deformation to unscrew the cap.
