The cap is unlocked from the tube by lifting the spokes out of engagement, by means of a ring, with the lugs.
4 Claims, 8 Drawing Figures CHILD RESISTANT CLOSURE FOR COLLAPSIBLE I TUBE BACKGROUND OF THE INVENTION As is well known, children, and particularly very young children, are attracted to containers, and to opening containers. Where such containers have toxic or otherwise dangerous contents, injury and even death can result should the child gain access to, and consume- 'or otherwise expose himself to, the container contents.
Num'erous different closures have been developed in an effort to prevent children from opening containers. These past efforts appear to be primarily directed to relatively rigid containers, such as glass and plastic bottles.
The present invention is concerned with collapsible tubes of the standard, common types, including those of aluminum, tin, lead and plastic.
SUMMARY OF THE INVENTION A standard common type of collapsible tube, having a body, shoulder and threaded neck portion, is made in ,the usual, prior art way with standard machines. How- DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, a standard, flexible, collapsible tube 20, of any suitable material, such as tin,
I lead. plastic. or aluminum, has a wall 21 of circular ified to include integrally with the cap, and extending radially therefrom, spokes joined at their outer end by a ring. The spokes are flexible in a direction longitudinal of the tube, but relatively rigid against rotation with respect to the threaded cap.
To lock the cap on the tube, the cap is threadedly engaged on the tube until the spokes come into engagement with each of the lugs, which have a beveled portion thereon. The spokes flexibly ride up the bevels and over the lugs.
When the cap is fully screwed on the neck of the collapsible tube, the spokes engage the lugs preventing unscrewing of the cap.
The features of the invention described above can be made with standard collapsible tube machinery, including standard dies and standard molds. No special mate rial is needed for either the tube or cap; presently used material can be continued to be used. The tube can continue to be automatically capped on standard equipment, as in the present practice.
To unlock the cap, the spokes are lifted out of engagement with the lugs by means of the. ring, and the cap unscrewed.
BRIEF DESCRIPTION OF THE DRAWINGS of the invention.
FIG. 5 is a perspective view of the closure of FIGS. 5 to 7.
cross section, with a suitable bottom seam or other closure 22, as seen in FIG. 8. At the top thereof, tube 20 has a shoulder 23, integral with wall 21, formed at a suitable, sloping angle to the wall, for instance 120. The shoulder 23 rises to integrally join with an externally threaded neck 25, adapted to receive an internally threaded cap 26. Cap 26 is formed of a suitable plastic, such as low density polyethylene.
The components described so far are conventional, mass produced, collapsible tube containers of the type well known, and used for instance for toothpaste, ointments, creams, and other relatively viscous liquids.
In the present invention the shoulder 23 of the tube 20 is modified by forming therein raised lugs 27 at circumferentially spaced positions, radially disposed, on the shoulder surface. In producing the collapsible tube, the die is altered to provide for such a result.
In the invention, the cap 26 is modified-by integrally extending therefrom spokes 36, and a ring 37. Spokes 36 are formed to lie, when relaxed, in a direction which conforms to the slope of the shoulder 23 of tube 20 when cap 26 is screwed onto neck 25.
The spokes 36 are of a relatively thin cross section in the direction longitudinal of the tube, so that they can flex upward with respect to the cap, but relatively wide in the direction of rotation of the cap with respect to the tube.
The ring 37 is relatively thick and extends upwardly to provide a grasping portion for the user. The ring 37 is in effect a flexible ring which seeks disposition in a given plane, thus positioning the spokes 36 in the direction longitudinal of the tube 20, while permitting the spokes 36 to be flexed out of the given plane when desition in a certain plane, even after having been displaced, at circumferentially spaced positions, out of the plane.
In the embodiment of FIGS 1 through 4, there are eight spokes 36 extending integrally from the cap 26 and joined to ring 37. Spokes 36 form eight rectangular openings 38 as shown. Eight lugs 27, of the type described earlier, are circumferentially spaced, and radially disposed on shoulder 23, so that they correspond with openings 38 when the cap 26 is fully threaded onto neck 25.
In use, cap 26 is initially threaded onto neck 25 of the tube 20 in the usual manner, by standard automatic capping machines @r by hand. The structure of the invention does not interfere with the usef such machines, or hand capping, since, in the invention, the basic prior art tube and cap are not changed.
During capping, as the cap 26 becomes increasingly threadedly engaged with the neck, the spokes begin to interfere with lugs. Since the cap 26 is being threaded on the tube in a clockwise direction, the spokes 36 engage bevel 28 of the lugs 27 during such interference. The spokes 36 being flexible in a direction longitudinal of the tube, individually ride up the bevel and then return to their downward position after they pass over the lug under their own bias, and from the effect of ring 37. Ring 37 is selectivelg' distorted out of its relaxed plane during such engagement of the spokes 36 and lugs 27, but returns to its given plane when the interference is past.
' When the cap is screwed fuIIy ontO neck 25, as shown for instance in FIGS. 1 to 3, spokes 36 extend along shoulder 23, being held in such position by the stiffness of the spokes themselves, as well as by the effect of ring 37.
In 'this position, wherein cap 26 is screwed closed onto neck 25, the cap 26 cannot be opened by merely rotating the cap in a counterclockwise direction from the container, because spokes 36 come into engagement with abrupt surface 30 on lugs 27. Since the spokes 36 are relatively wide, they do not yield against the'force seeking to remove the cap 26 from the tube 20, thus preventing the uncapping of the container.
In order to unscrew the cap from the container, it is necessary for the user to proceed as shown in FIG. 8. The user must grasp the tube 20 with one hand 40, and support the tube. The user, with the fingers 41 of his other hand, then grasps ring 37 formed on cap 26, and lifts the ring away from shoulder 23, in at least two, and desirably three, circumferentially spaced positions. In so lifting ring 37, the user also lifts spokes 36 out of interference with lugs 27, thus permitting cap 26 to be unscrewed in a counterclockwise direction. When the cap is sufficiently unscrewed, the user may allow ring 37, and spokes 36 to return to their relaxed position, out of any further interference with lugs 27. The cap 26 can then be unscrewed and removed in its normal way.
In the embodiment of FIGS. through 7, in order to permit a locking effect without having to turn the cap unduly beyond its initial seating position, there are more openings between the spokes than there are lugs.
For instance, there are shown ten openings 38 and five lugs27.
To provide a more adequate grasp of the'cap 26, when necessary, the cap may be lengthened as shown at 15, in FIGS. 5 and 7. The upper segment 45 of the cap may have a seal-puncturing spike as at 46, as well known. The cap, however, should not be of such length that the fingers will not be somewhat in abutment with the ring 37, since such abutment tends to force the ring 37 and spokes 36 against the shoulder 23 to secure firm locking.
As seen for instance in FIG. 7, it is further desirable that the diameter of the ring 37 be somewhat smaller than the outside diameter of the tube 20, so that it is somewhat unwieldy to grasp and lift the ring 37 when unlocking and unscrewing the cap 26.
It should be further noted that, as illustrated in FIG. 8, in unlocking the cap 26, and removing, it is necessary for the user to grasp the collapsible tube 20 with one hand, and hold the tube in a supporting position. This, of course, is equally applicable to a child, so that by the very nature of the container, one hand of the child is immobilized.
The invention will ofi'er resistance to a child opening a collapsible tube container since the child will, where he is seeking to remoye the cap ina conventional manner, attempt to turn the cap 26 either clockwise, or counterclockwise. Obviously a clockwise movement will not permit removal,since the cap 26 becomes further engaged. A counterclockwise'twis t by the child will be resisted by the engagement of the spokes 36 with the lugs 27. Notwithstanding that the spokes 36 are flexible in a direction longitudinal of the tube, they are most rigid in opposing a counterclockwise twist since their dimension in the flat plane is a substantial one, and thus a flat twist will be resisted. Additionally, the spokes 36 are given further rigidity against movement which permits turning, by the interlocking feature of the ring 37 with the spokes 36.
In order for the cap 26 to be removed by turning in a counterclockwise direction, it is necessary to-lift the spokes 36 out of engagement with the interfering lugs 27. To do this, it is necessary to lift the ring '37 from its normal or relaxed position wherein the spokes .36 are engaged with the lugs 27. However, the ring 37, being flexible, but nevertheless somewhat stiff, is of such a particular nature that by lifting at one point, the entire ring is not lifted.
It is necessary to lift the ring 37 in at least two points and for best results, in at least three points.
The ring 37 along with the cap 26 then twisted counterclockwise to disengage the cap 26 from the tube 20. The ring 37 must be held by the fingers until the cap 26 is sufficiently unscrewed so that when the ring 37 is released, there is ,no longer interference with the lugs 27.
The cap removal as explained is sufficiently intricate to generally foil a child of approximately four and onehalf, or younger, while permitting a relatively convenient use for the general population.
