Definitions

  • THIS INVENTION relates to containers for fluids such as liquids and fluent solid materials such as powders and granular materials, and which have necks through which contents can be poured.
  • Containers which have necks for pouring fluid contents are particularly convenient to use in that they are merely required to be tipped or inverted to allow the fluid contents to be discharged.
  • the containers are, however, difficult to store because the presence of the neck does not allow the containers to be stacked in a stable manner one upon another. While stacking fluid containers in an unstable manner may not be a significant problem in many cases, it can present risks in situations where the chemicals are hazardous.
  • the present invention seeks to provide a fluid container which can be stacked with similar containers in a stable manner.
  • the invention resides in a container having a top portion and a bottom portion, the top portion defining a neck having a mouth through which fluid contents of the container can be poured, and a bottom portion having a recess for accommodating the neck of a similar container thereby to allow the containers to be stacked one upon another.
  • the container includes a first support surface surrounding the neck and a second support surface surrounding the recess, the two support surfaces being so arranged that the first support surface of one container supports the second support surface of a corresponding container stacked on it.
  • the first support surface is disposed at the innermost end of the neck of the container and the second support surface is adjacent the outer end of the recess.
  • the neck of the container and the recess are so shaped and dimensioned that there is no load supporting engagement between the neck of one container and the recess of a further container stacked upon it.
  • the load contact between the two containers is at the respective first and second surfaces.
  • locating means may be provided for locating stacked containers one with respect to another to resist lateral displacement therebetween.
  • the locating means may comprise a projection provided on one of the support surfaces and a corresponding recess provided on the other of the support surfaces.
  • the projection is in the form of a circumferential rib and the recess is in the form of a continuous channel.
  • the container comprises a top wall, a bottom wall and side wall means extended between the top and bottom walls, the neck being formed in the top ⁇ . ⁇ a 1 1 1 a n _ _ ⁇ V_ ____ ycm ___ __• _-• _*_._ _ i*- -* 1 -i -4- >_ e» "V" -.”. .*.

  • the mouth through which the contents can be poured is preferably designed to allow the contents to be discharged without excessive splashing and dripping.
  • the mouth is provided with a pouring lip having an inner face which diverges outwardly in the direction towards the open mouth.
  • the pouring lip preferably has a sharp edge at the outer end thereof.
  • the sharp edge may be created by providing a circumferential groove in the outer face of the neck immediately adjacent the mouth, the groove having a flank which defines an outer face of the pouring lip.
  • a releasable closure for the aperture defined by the mouth of the container, the closure being adapted for rapid engagement and disengagement with the neck of the container.
  • This feature may be achieved by providing a tapered male thread on the neck, the direction of the taper being inwardly towards the mouth of the neck, and the closure being provided with a mating female thread.

  • Fig. 2 is a schematic perspective view of the underside of the container
  • Fig. 3 is a schematic perspective view showing several containers according to the embodiment stacked one upon another;
  • Fig. 4 is a cross-sectional view of the container according to the embodiment.
  • Fig. 5 is a fragmentary sectional view of two containers, one stacked upon the other;
  • Fig. 6 is a fragmentary sectional view of the container in an invented condition fitted with a dispensing cap.
  • the embodiment shown in the drawings is directed to a container for storing and handling hazardous liquids such as herbicides and pesticides used in the agriculture industry.
  • the container is formed of plastics material and comprises a top wall 11, a bottom wall 13, and a side wall 15 between the top and bottom walls. While the side wall 15 can be of any suitable shape in cross-section, in this embodiment it is generally square with rounded corners.
  • the top wall 11 includes a generally frusto-conical formation which defines a neck 17 which terminates at a mouth 19.
  • the outer section 18 of the neck adjacent the mouth 19 has a slight inward taper, the purpose of which will be explained later.
  • the mouth 19 defines an aperture through which the l q uid contents of the container can be poured.
  • a closure means 20 such as a cap is provided for selectively closing the aperture in a sealed manner.
  • the neck 17 of the container is surrounded by a first support surface 21 which is located at the edge of the top wall 11 immediately adjacent the junction with the side wall 15.
  • the bottom wall 13 of the liquid container comprises an outer section 23, an intermediate section 25 and an inner section 27, as best seen in Fig. 4 of the drawings.
  • the intermediate section 25 is generally frusto-conical in shape so as to set the inner section 27 inwardly of the outer section 23 to define a recess 29 at the bottom of the container.
  • the recess 29 is adapted to accommodate the neck 17 and accompanying closure cap 20 of a corresponding container when the containers are stacked one upon another, as best seen in Fig. 5 of the drawings.
  • the outer section 23 of the bottom wall 17 provides a base for the container when resting on a planar surface such as the ground or a floor.
  • the outer section 23 also defines a second support surface on the container which can rest on the first support surface 21 of a corresponding container when the containers are stacked one upon another. Engagement between the two support surfaces provide the only load bearing contact between the stacked containers.
  • Fig. 5 of the drawings it will be noted from Fig. 5 of the drawings that the neck 17 and cap 20 of the lower container is spaced from the recessed portion of the bottom wall of the upper container, with the result that there is no load bearing contact between those parts of the two stacked containers.
  • means 31 is provided for locating the stacked containers one with respect to the other to resist lateral displacement between the containers.
  • the locating means 31 comprises a locating projection 33 on the first surface 21 for engagement in a complementary locating recess 35 formed in the second surface 23.
  • the projection 33 is in the form of a circumferential rib on the first surface and the corresponding recess 33 is in the form of a circumferential channel formed in the second surface.
  • the aperture defined by the mouth 19 of the container is provided with a pouring lip 41 designed to avoid excessive splashing and dripping of liquid contents being poured from the container.
  • the pouring lip 41 has an inner face 43 which diverges outwardly in the direction towards the open mouth; that is, the inner face diverges outwardly along the direction of flow out of the container.
  • the outer face 45 of the pouring lip is defined by a flank of a circumferential groove 47 formed in the outer face of the neck immediately adjacent the mouth 19.
  • the inner and outer faces of the pouring lip converge to a sharp edge 49 at the outer end of the pouring lip.
  • the sharp edge 49 is achieved by having the inner and outer faces of the lip disposed at an angle of less than 45 * with respect to each other.
  • the feature of the lip having an inner face which diverges outwardly in the direction towards the open end of the mouth together with the sharp edge at the outer end of the lip facilitates pouring of liquid contents from the container without excessive splashing and dripping.
  • FT.rtti ⁇ r ⁇ iore, the sha._ri"> edge 49 and the undercut immediately adjacent the lip formed by the groove 47 allows the liquid contents to be poured from the container with little (if any) curling of liquid under the lip to contaminate the exterior of the container.
  • the outer section 18 of the neck is adapted to accommodate the closure cap 20 and tapers inwardly towards the mouth of the container.
  • the purpose of the inward taper is to enable a taper-lock thread to be utilised for releasably securing the closure cap to the neck.
  • the taper-lock thread comprises a male thread formation 51 on the neck and a complementary female thread formation 53 on the closure cap. This threaded arrangement allows the closure cap to be rapidly fitted onto, and removed from, the neck of the container. In particular, it allows the closure cap to be completely engaged, and disengaged, with only approximately one turn of the cap.
  • the thread arrangement reduces the likelihood of the closure cap "freezing" onto the neck which is the situation which occurs sometimes with threaded closure caps for conventional pouring spouts necks of conventional containers. Furthermore, the tapered thread provides a more secure seal than does conventional threads.
  • a handle (not shown) may be provided at any convenient location on the container to facilitate ease of handling.
  • the container can be fitted with a dispensing cap 55 designated to facilitate dispensing of the contents of the container.
  • the dispensing cap 55 is illustrated in Fig. 6 and is adapted to engage the outer section 18 of the neck 17 in a similar manner to the closure cap 20 once the latter has been removed.
  • the dispensing cap is fitted with a fluid inlet 57 and an cutlet 59 through which the contents of the container can discharge.
  • the inlet 57 is adapted for connection to a source of dispensing fluid (such as air) which can be injected into the container to expel the contents under pressure through the outlet 59. Where the contents are required to be mixed with another liquid (such as water) for use, the liquid may function as the dispensing fluid.
  • the inlet 57 has a discharge end 61 configured as a nozzle to facilitate mixing between the contents of the container and the dispensing fluid.
  • a cleansing fluid can be injected into the container through the inlet 57 if desired. This is desirable in circumstances where the contents of the container were of a hazardous nature.
  • the features of the tapered thread to allow coupling between the container and the dispensing cap with only about one turn of the cap is particularly advantageous as it allows fitting of the cap without excessive twisting of the hose lines.
  • the container according to the embodiment has several features which assist in safe handling of toxic chemicals and other hazardous liquids. As explained previously, the container can be stored in a stacked arrangement with similar containers in a relatively stable manner , and can also be transported in such a stacked arrangement.
