Definitions
- ABSTRACT Containers are provided with ratchet locking mechanisms that prevent loosening of closures from vibration or otherwise but may be easily released when the closure is to be removed.
- OBJECTS It is among the objects .of this invention to provide a container with a body member having a pour opening and associated closure member that are positively locked in fluid engaging relationship by a pawl and ratchet means and by longitudinal restraining engagement means. It is to provide such a container wherein there is a conjunctive relationship between these means that requires the locking means to be continuously engageable while the longitudinal restraining means is disengaged. Further, eitherthe body member or the closure may carry either the pawl or the ratchet, selection of the one determining the other. Other portions of the body member may cooperate with the closure to form a pour surface and/or a security seal.
- FIG. 1 illustrates the container. 1
- FIG. 2 illustrates the'closure having a plug engage-
- FIG. 5 illustrates the release member and'ratchet of FIG. 4.
- the closure (.I) and the body (4) together comprise a container for fluids.
- pawl (2) engages each member of the ratchet (5) annularly, disposed about the pour opening.
- the pawl successively engages'each ratchet member, this provides positive locking of the closure against loosening.
- the pawl will be in releasable engagement with the ratchet by means of the release member (3) shown as an upstanding thumb lever. To loosen the closure by disengagement from the pour opening, the pawl-ratchet engagement must simultaneously be released by the release member.
- the pawl again locks with the ratchet to prevent loosening.
- the closure is positively locked against the body bothwhile closing and loosening.
- the closure and pour opening are shown adjacent to an edge of the body; the elevated portion (6) of the body forms a liquid retention area so that the pour opening and closure can form a pouring surface over the body edge.
- the body may have a handle (7) to transport the container. In the handle is a security member '(8),
- a similarsecurity member (3a) may be on the pawl. These may be used for threading tamper proof indicators such as sealed ribbons or wires between the closure and handle.
- the ratchet as shown is a full annular section about the pour opening. It may also have the segment of teeth removed that are on the edge of the body in the direct pourpath of the pour opening in order to have the edge molded properly and to facilitate pouring. There will be enough remaining adjoining ratchet teeth in the annular section to positively lock the closure to the body.
- Both the closure and the body may be made of any suitable material, such as thermoplastic resin, that has sufficient impact strength to pass the four-foot drop test for containers in the interstate shipment-of harmful, dangerous or toxic liquids.
- the invention is particularly suitable for polyethylene containers in which loosening by vibration during transportation is an especially acute problem.
- the construction embraces wide mouth containers as well as those having a relatively small pour opening. Tight head containers of 5 to 55 gallon capacity are especially preferred.
- the closure (Ill) has a pawl (12) and a re lease member (13).
- this closure has a threaded plug (14) to engage an appropriately threaded pour opening.
- a construction such as" the elevated body portion ('6) shown in FIG. 1 would act to channel liquid being poured over the edge'of the body.
- the closure (21) may have two or more pawls (22) joined to a common release member (23). These pawls may be spaced from each other a sufficient distance so that one pawl will engage the full ratchet element surface when the other pawl is not so engaged, a distance of at least one half the length of a ratchet element being preferred.
- FIG. 1 The embodiment of the invention-in which the closure is the member carrying a ratchetis shown in FIG.
- the closure (41) has a ratchet (42) on the release member (43).
- On the body member there are one or a pour opening and the ratchet will positively lockthe closure in each position against loosening.
- the release member and ratchet In order to open the pour opening, the release member and ratchet must be slide free of engagement with the pawls on the body while the closure is loosened.
- FIG. 5 shows the release member of FIG. 4insection.
- Release member (51) has key slots I about the fluid retaining member by adhesives or thermo welding.
- Key slots (54) have enough compressible material (55) so that a constant tension will be exerted against the keys to keep the ratchet (52) engaged with its pawls.
- the slot itself is of a length and width sufficient to allow the ratchet to be disengaged when the release member is slid away from the ratchet.
- the closure will be positively locked to the body. Even if the closure is not fully secured to the body, the locking mechanism will prevent loosening of the closure. Moreover, the conjunctive relationship between the locking mechanism and the longitudinal engaging means requires simultaneous disengagement of these mechanisms to loosen the closures. This prevents accidental openings by small children as well as vibrational loosening. The manipulative technique to perform this simultaneous disengagement may be easily done by one hand with the closure and body combinations set forth above.
- the pour opening and closure may be located on the top horizontal surface or on a vertical surface or on an oblique surface of the body.
- said locking means having a ratchet annularly disposed about said pour opening and carried by one member of said body and said closure,
- said pour opening and said closure being located adjacent to an' edge of saidbody member and an elevated fluid engaging portion of said body memher being adjacent to said closure and pour opening and cooperating to form a pouring surface.
- thermoplastic body and closure For a hollow container having a thermoplastic body and closure,
- said locking means having a ratchet annularly disposed about said pour opening and carried by said body
- pawls carried by said closure operable to engage said ratchet to positively lock said I closure to said body against disengagement when said closure is in fluid retaining relationship with said body, said pawls being hingedly attached to and extending outwardly from said closure and being disposed in the region of said closure adjacent to said body,
- said pour opening and said closure being located adjacent to an edge of said body member and an elevated fluid engaging portion ofsaid body member being adjacent to said closure and pour opening and cooperating to form a pouring surface.
- thermoplastic body and closure For a hollow container having a thermoplastic body and closure,
- a one-piece closure adapted to close said pour opening to retainfluid contents in said container, said closure being in the form ofa cap with internal threads, and having pawls extending from the surface of said cap,
- pawls carried by said closure, said pawls being disposed in the region of said closure adjacent to said body and said pawls being hingedly attached to and extending outwardly from the surface of said closure, said pawls being operable to engage said ratchet to positively lock said closure to said body against disengagement when said closure is in fluid retaining relationship with said body,
- each pawl of said locking means being in conjunctive relationship with said longitudinal restraining engagement so that said locking means is engageable for positive locking while said longitudinal engagement is disengaged.
