This invention relates to closures with snap-type hinge caps.
One common type of closure which has received extensive use is the closure known as the snap-type hinge cap which includes a first part adapted to interengage with the open neck of a container, a second part forming a cap and an integral hinge interconnecting the first and second parts. A typical closure of this type is shown in U.S. Pat. No. 4,638,916.
With the increase in emphasis on making packages tamper indicating or tamper evident, it may be required that that tamper evident feature be applied, if possible, to a closure with a snap-type hinge cap. The first part which interengages with the open neck of the container can be provided with tamper indicating devices such a shrink band or as shown in U.S. Pat. Nos. 4,378,893, 4,418,828, and 4,669,623.
However, as far as I am aware, no satisfactory tamper indicating construction has been provided for indicating tampering with respect to the first and second parts of such a closure.
Accordingly among the objectives of the present invention are to provide a tamper indicating closure and package of the snap-type hinge cap; which is simple and inexpensive; which can be readily applied; and which will provide effective tamper evident features.
In accordance with the invention, a tamper indicating device in the form of a locking ring is formed and connected by a integral hinge with either the first or second part of the closure and is adapted to be folded into position between the first and second part when the closure is first closed. Upon being closed, the locking ring will project beyond the periphery of the two parts and will provide an indication that the closure has not been tampered with. In order to provide access to the contents, the tear strip will need to be torn at the hinge line of the locking ring to the closure part.
FIG. 2 is a plan view of the closure in open position.
FIG. 4 is a fragmentary sectional view taken along line 4--4 in FIG. 1.
FIG. 5 is a plan view of a modified form of closure.
FIG. 6 is a longitudinal sectional view taken along the line 6--6 in FIG. 5.
FIG. 7 is a view showing the modified closure in closed position.
Referring to FIGS. 1-4, the closure embodying the invention is of the snap-type hinge variety comprising a first plastic part 10 including a base wall 10a and skirt 10b adapted to be engaged with the neck of a container C as by threads 11 and a second plastic part 12 or cap including a base wall 12a and skirt 12b connected to the first part 11 by an integral hinge 13. The first part 10 includes an axial spout 14 that is adapted to be closed by a complementary plug 15 on the second part 12 when the part 12 is moved into closed position. Such closures are well known in the art and shown in U.S. Pat. No. 4,638,916, which is incorporated herein by reference.
In accordance with the invention, a tamper indicating device in the form of a integral locking ring 16 is molded to one of the closure parts, shown in FIGS. 1-3 as being connected by an integral hinge 17 to first part 10.
The hinge 17 of locking ring 16 includes a fold line 18 such that the ring 16 may be folded about line 18 to bring ring 16 over spout 14. The ring 16 includes a circumferential wall 19 that extends axially from the ring 16 and has an external annular bead 20 thereon. Wall 19 telescopes over spout 14. The base 12a and part 12 includes a second axial wall 21 surrounding axially spaced radially outwardly from axial spout 15 which has an internal annular bead 22 that interengages the bead 20 to lock the second part 12 in closed position. The hinge 17 of locking ring 16 includes a tear strip 23 connected by weakened lines 24, 25 thereto. Tear strip 23 includes an axially extending tab 26 extending from the strip 23 for grasping the strip 23 so that it can be severed.
After filling of the container, a closure is threaded on the container. Prior to this, the locking ring 16 is preferably folded to the position shown in FIG. 4.
After the closure is threaded on the container, a tamper indicating means is provided between the part 10 and the neck of the container, herein shown as a shrink band 30. Alternatively, other mechanical tamper indicating devices may be used as shown, for example, U.S. Pat. Nos. 4,378,893, 4,418,828, and 4,669,623, which are incorporated herein by reference.
As shown in FIG. 4, when the closure is applied to the container, the portion 23 of the hinge 17 projects beyond the periphery of the closure giving a visual indication that the contents have not been tampered with. If this is torn, then a user knows that the package has been tampered with. In order to provide access to the contents, the portion 23 must be torn permitting the closure part 12 together with the locking ring 16 to be swung upwardly away from the part 10.
In the form shown in FIGS. 5-7, the locking ring 16a is hinged to the part 12 rather than the part 10. In all other respects, the closure is the same.
In the interest of clarity, the parts are provided with the same reference numerals with the suffix a. Tab 26a in this form extends laterally from hinge 17a.
Ring 16a functions to engage directly an external annular bead 20a on the axial spout 14a and axial wall 22a on part 12a engages the ring 16a (FIG. 7).
It can thus be seen that there has been provided a tamper indicating closure and package of the snap-type hinge cap, which is simple and inexpensive, which can be readily applied, and which will provide effective tamper evident features.
