Device and method for effecting relative motion within a closed sales display package

Abstract

A device for effecting relative motion of movable components of a product within a closed sales display package translates a force exerted in one direction so that the force is applied in a second direction through buckling of a motion spring. The motion spring is two-dimensional, i.e., flat, and is oriented so that its flat surfaces face the direction of motion and so that its top and bottom edges are secured to opposite sides of a sales package. Pressure that is exerted vertically on the top and bottom edges of the spring causes the spring to buckle about a horizontal axis, thereby deflecting the flat surface of the spring in a horizontal direction that is perpendicular to both the vertical direction of force and the horizontal buckling axis. The motion spring is secured at its top and bottom vertical edges to the front and back, respectively, of the sales package. When the spring is to be used in conjunction with the rotatable toothbrush of U.S. Pat. Nos. 5,120,225 and 5,186,627, the spring is secured to the toothbrush by supporting the toothbrush handle around its periphery. Exerting force vertically on the spring through the sales package creates buckling and deflection of the area of the spring secured to the toothbrush handle, thereby moving the handle in the direction of deflection of the spring, which is longitudinally with the respect to the toothbrush handle. Release of the vertical force will allow the motion spring to relax so that the toothbrush handle can be returned longitudinally to its original position.

Description

BACKGROUND OF THE INVENTION

The present invention relates to sales packaging for consumer products that involve relative motion of one or more of their component parts. More particularly, this invention relates to a device and a method for effecting relative motion of a component part of a consumer product within a closed sales display package. Still more particularly, this invention relates to a device and a method for demonstrably effecting longitudinal motion of the handle of a toothbrush relative to the head of a toothbrush having rotatable bristles for the purpose of rotating the bristles in view of a consumer, while the toothbrush is encased within a sealed sales display package.

It is common in the retail business, particularly in the toy and consumer products industries, to display saleable products such that the actual operation of the products can be demonstrated to the consumer. In this way, because the consumer is able to actually operate the product or toy prior to purchase, purchaser awareness and satisfaction are increased. However, due to the fragility of complex consumer products, frequent handling and trial usage by consumers often leads to damage or deterioration of display products. Also, open display of unpackaged products increases the risk of shoplifting of the consumer products that are on display. Therefore, many retailers are loathe to display unpackaged or unsecured products.

Retailers often instead prefer to display products within closed sales display packages in order to avoid deterioration and breakage of the products due to rough trial usage and in order to avoid theft and shoplifting of the loose products. Unfortunately, display of a product within a closed sales display package often does not allow relative motion of the components of that product to be demonstrated to the consumer.

One type of consumer product or toy that may be operable from outside a closed sales display package is one that is electrically operated. Operating the product from outside the closed sales package is often accomplished by situating an electrical contact or an activation button on the surface of the device adjacent the deformable packaging. When the item is packaged within a closed sales display package, the deformable packaging is situated such that an interested consumer can operate the device by pressing the activation button through the deformable display package and completing a circuit.

An example of an electrically-operated toy that is operable by pressing an activation button through the display package is described in U.S. Pat. No. 4,925,025. This type of toy typically involves a tiny bulb that is lit up or involves some other activation device with electrical components. Unfortunately, however, electrically operated toys often do not possess the type of visibly movable component parts that allow a consumer to actually see the operation of the device, and the consumer thus does not get the satisfaction of watching the components move.

Other types of consumer products or toys that may be operated from outside a closed sales display package are mechanical products that utilize a means for activating the product, which means extends partially outside the package. For example, talking toys are operable by way of a pull string that extends outside of the otherwise-closed sales display package allowing a consumer to demonstrate the speech mechanisms of the toy without opening the sales display package. Similarly, a sales display package that includes a pivoted lever assembly having one portion extending outside the package and another portion inside the package enables a consumer to activate a switch within the package by actuating the exterior lever portion, causing the interior lever portion to activate the switch and thereby operate the device. An example of an external lever-operated device is shown in U.S. Pat. No. 5,188,222. Again, however, the movable components of the products displayed in these packages are situated within the product and their movements are not visible to a consumer. Thus, pulling a pull string or activating a switch through a lever will not give the consumer the satisfaction of watching the components move. Moreover, because these actuation devices extend partially outside the display packages, the packages must be open in some manner, leaving them more susceptible to shoplifting, breakage or deterioration from moisture.

Various mechanical consumer products that have visibly, mechanically movable components are sold in closed sales display packages. For example, U.S. Pat. Nos. 5,120,225 and 5,186,627 disclose a hand-actuated toothbrush with rotatable bristles, in which a group of bristles mounted within the toothbrush head is connected to a movable handle by way of a rack and pinion within the base of the head, such that longitudinal reciprocation of the handle causes the group of bristles to be rotated in response. Unfortunately, consumers have no way of viewing the mechanical motion of the component parts of the rotatable toothbrush or of other consumer products while the products are within the closed sales display packages because there is no mechanism or device for visibly demonstrating to a consumer the mechanical motion of components of a device that is within a closed sales display package.

It is, therefore, an object of this invention to provide a device and a method for visibly effecting relative motion of movable components of a consumer product encapsulated within a sealed sales display package.

It is another object of this invention to provide a device that visibly effects linear motion of an elongated object that is encapsulated within a closed sales display package.

It is a further object of this invention to provide a device that visibly effects the longitudinal motion of the handle of the hand-activated rotatable toothbrush disclosed in U.S. Pat. Nos. 5,120,225 and 5,186,627 such that the rotatable group of bristles rotates in response, while the toothbrush is encapsulated within a closed sales display package.

These and other objects of the invention will become more apparent in the discussion below.

SUMMARY OF THE INVENTION

The above objects of the invention are accomplished by providing a "motion spring" that translates a force exerted in one direction so that the force is applied in a second direction through buckling of the motion spring. The motion spring is two-dimensional, i.e., flat, and is oriented so that its flat surfaces face the direction of motion. Pressure that is exerted vertically on the top and bottom edges of the spring causes the spring to buckle about a horizontal axis, thereby deflecting the flat surface of the spring in a horizontal direction that is perpendicular to both the vertical direction of force and the horizontal buckling axis.

The motion spring is secured at its top and bottom vertical edges to the front and back, respectively, of the sales package. When the spring is to be used in conjunction with the rotatable toothbrush of U.S. Pat. Nos. 5,120,225 and 5,186,627, the spring is secured to the toothbrush by supporting the toothbrush handle around its periphery. Exerting force vertically on the spring through the sales package creates buckling and deflection of the area of the spring secured to the toothbrush handle, thereby moving the handle in the direction of deflection of the spring, which direction is longitudinal with the respect to the toothbrush handle. Release of the vertical force will allow the motion spring to relax so that the toothbrush handle can be returned longitudinally to its original position.

DETAILED DESCRIPTION OF THE INVENTION

The device for effecting relative motion of component parts of a product within a closed sales display package consists of a thin, flat, planar motion spring 1, as shown in FIGS. 1 and 2. The device of this invention is made of plastic, metal or some other springy, resilient material. The device 1 is fashioned so that its thickness 2 is small compared to its height 3 and width (not shown), and so that its height 3 is greater (at most regions) than its width. When a force F is exerted vertically on the top and bottom edges of the upright motion spring, as shown in FIG. 1, the motion spring 1 is caused to buckle into an arched shape, as shown in FIG. 2. Because the height of the motion spring is greater than its width, the motion spring is fashioned so that buckling will occur only in one direction, i.e., about a horizontal axis H parallel to the plane of the motion spring 1. Deflection 10 of the motion spring will occur at the middle portion 4 of the motion spring 1 and in a horizontal direction D perpendicular to the horizontal buckling axis H (which is parallel to the plane of the motion spring) and to the vertical direction of force F.

In order to assure proper buckling of the motion spring and deflection in the desired direction, the spring could be given a very slight initial arched shape in the desired direction of buckling. This initial predisposed shape will ensure that the motion spring will buckle in the arched direction. However, the total movement of the middle portion of the motion spring will be less than the maximum possible deflection because the motion spring is already partially deflected in the desired direction. Thus, although buckling in the desired direction is ensured, deflection of the motion spring and movement of the moveable component parts of the displayed product is not maximized.

An alternative way of assuring buckling of the motion spring and deflection in the desired direction without predisposing the flat motion spring to a particular shape, as illustrated in FIG. 3, is by forming the top and bottom edges 5,6 of the motion spring 1 into widened "feet" 7,8. The feet can be formed by bending, molding or otherwise forming the top and bottom edges 5,6 of the motion spring 1 such that a portion of each edge extends a short distance 9, or depth, in a direction somewhat perpendicular to the plane of the motion spring. The depth 9 of the feet 7,8 allows a greater area on the motion spring top and bottom edges 5,6 to which a force F may be exerted. Application of the force F at a distance, however small, from the plane of the motion spring creates a torque T or moment about the edges 5,6 of the motion spring 1 about the horizontal axis H in the direction D opposite to that in which the feet extend, thereby causing buckling to occur only in that direction D. The feet thus create a natural resistance of the motion spring, at the junction of the edges 5,6 of the motion spring 1 and the feet 7,8, to bend further in the direction of the feet, and the motion spring is almost forced to buckle in the direction D opposite to that in which the feet extend.

In the presence of "footed" edges of the motion spring, movement of the middle portion of the motion spring can be increased even beyond the normal maximum deflection because the directed buckling in the direction away from the feet occurs even for a spring with an oppositely predisposed initial arch. This is shown in FIG. 4. The torque T created about the edges 5,6 of the motion spring 1 due to the presence of the feet 7,8 will tend to cause buckling in the direction D away from the feet 7,8 even when the motion spring 1 has an initial arched shape in the opposite direction, that is in the direction of the feet. Thus, in a preferred embodiment, a motion spring 1 with an oppositely predisposed initial arch can be used with widened feet 7,8 at its edges 5,6. This embodiment enables a greater deflection of the motion spring to be achieved in the desired direction, as the middle portion of the motion spring must first deflect the distance of the predisposed arch and only then deflect its normal distance.

In order for the motion spring device to effect the movement of component parts of a product within a closed sales display package, the motion spring must be abutting or secured to a movable part of the product so as to cause the movement. Preferably, the portion of the motion spring that is abutting or secured to the product is the middle portion of the motion spring, i.e., the portion that deflects the most in the horizontal direction. The movable component of the packaged product should somehow be abutting or connected to the middle portion of the motion spring so that buckling and relaxing of the spring will cause back and forth motion of this portion and of the product connected thereto. Also, the top and bottom edges of the motion spring must be secured or connected to the inside of the sales display package at opposite sides of the package so that a consumer can exert pressure against the outside of the sales display package adjacent the top and bottom edges of the motion spring. This pressure by a consumer applies a force to the top and bottom edges of the motion spring, thereby deforming the motion spring and causing movement of the movable component part of the product abutting the motion spring or secured thereto. These connections can be by any means, such as friction, adhesive or other means.

In a preferred embodiment of this invention for use with the rotatable toothbrush of U.S. Pat. Nos. 5,120,225 and 5,186,627 ("the patented toothbrush"), as shown in FIG. 5, the middle portion 14 of the motion spring 11 is widened and a rectangular hole 13 is formed therethrough in order to allow the motion spring 11 to be attached to the handle of the rotatable toothbrush. The handle of the patented toothbrush has several ridges oriented transversely across the top of the handle normally used for gripping by the consumer during use. The handle is inserted through the rectangular hole 13, and the motion spring 11 is secured to the handle by snapping the downward-facing top edge 19 of the rectangular hole 13 between two of the transverse ridges on the top of the handle. In a further preferred embodiment, the area of the rectangular hole 13 is substantially equal to the cross-sectional area of the toothbrush handle so that the handle fits snugly within the hole 13.

The motion spring must also be secured within the display package so that only the product components, and not the top and bottom edges of the motion spring, move. For this purpose, the motion spring has upper and lower support struts 17,18 that are respectively mounted within upper and lower support sockets of the display package. As shown in FIG. 5, these support struts 17,18, which can simply be widened extensions of the top and bottom edges 15,16 of the motion spring 11, are used to securely hold the top and bottom edges 15,16 of the motion spring 11 in place within the front and back of the display package, respectively. The support struts can, in a preferred embodiment, be in the form of shaped feet described above in order to assist in the buckling of the motion spring, in addition to securely holding the edges of the motion spring within the display package.

The method of operation of this invention within a package containing the patented toothbrush is shown in FIGS. 6 and 7. The movable toothbrush head 21 is securely located within a chamber 24 at the front end of the display package 23 such that any movement of the toothbrush head 21 while the toothbrush handle 22 is moved longitudinally within the sales package 23 is prevented. When a consumer presses on the transparent packaging cover on the front 25 of the sales package 23 and on the back cover 26 of the sales package 23, the consumer exerts a force F on the front 25 and back 26 of the sales package 23 containing the patented toothbrush, thereby exerting respective forces F on the top edge 15 and bottom edge 16 of the motion spring 11 secured thereto. The exerted forces F cause the motion spring 11 to buckle, as described above, resulting in a deflection 28 in the direction D of the middle portion 20 of the motion spring 11 attached to the handle 22 of the patented toothbrush, also described above. The deflection 28 of the middle portion 20 of the motion spring 11 moves the handle 22 of the patented toothbrush with respect to the stationary toothbrush head 21 in a longitudinal direction L that is substantially parallel to the direction D of deflection 28 of the motion spring 11. This relative longitudinal movement 28 actuates the rotation of the group of bristles 29 in the toothbrush head 21. Because the patented toothbrush is encased within a transparent sales display package 25, this activity all occurs within full view of the consumer who initially exerted the force F on the package 23.

In an alternative embodiment of this invention for use with the patented toothbrush, the longitudinal motion of the toothbrush handle and the rotation of the toothbrush bristles can be increased by using a motion spring having an oppositely predisposed initial arch. In this structure, as discussed earlier, the deflection of the middle portion of the motion spring, and therefore also the movement of the toothbrush handle attached thereto, can be increased even beyond the normal maximum deflection. Note that use of the oppositely predisposed motion spring arch should be used in the presence of the footed edges of the motion spring or in the presence of some other means for creating a torque in the direction of desired deflection, because otherwise the motion spring will not deflect in the desired direction.

In a further preferred embodiment of this invention, the motion spring is equipped with a press button 27, as shown in FIGS. 8 and 9, instead of upper support strut 17. One function of the press button 27, as shown in FIG. 10, is to give a consumer a larger target on which to press when attempting to effect the rotation of the toothbrush bristles 29 of the packaged toothbrush. Referring to FIG. 11, a consumer presses the button 27 through the clear display package 25 in order to cause motion of the toothbrush bristles 29. In addition, the press button 27 serves the same function as does the widened foot 7 on the top edge 5 of the motion spring 1 shown in FIGS. 3 and 4, that is to form a greater area on the top edge 15 of the motion spring 11 to which a force F may be applied, thereby allowing the force F to be applied at a distance 29 from the plane of the motion spring 11 and creating a torque T about the top edge 15 of the motion spring 11 in the direction of desired deflection. In addition to creating a larger target for a consumer to press, the press button 27 thus actually helps to increase deflection in the desired direction.

Furthermore, in the preferred embodiment having the press button, shown in FIGS. 8-11, the material that forms the motion spring 11 is of reduced thickness in a region 28 at the top edge 15 just below the press button 28. This region of reduced thickness functions as an integral hinge 28 to enable the motion spring 11 to deform into an arched shape while the press button 27 remains horizontal. In the absence of the hinge region 28, the press button 27, which can be held in a horizontal position by the display packaging 25, may form a cantilever-type joint with the motion spring and may thus prevent the motion spring from achieving full deflection. When the hinge region 28 is present, the press button 27 forms a simple pin-support-type joint with the motion spring 11 and allows full deflection even when being held in a horizontal position. A hinge region is not necessary when only the widened feet 7,8, not a press button 27, are present at the edges of the motion spring, as shown in FIG. 7, because the widened feet 7,8 tend to rotate with the edges 15,16 of the motion spring 11 and thus do not prevent the motion spring from achieving full deflection.

Thus, a device and a method for effecting relative motion of component parts of a product within a closed sales display package are provided. One skilled in the art will appreciate that the present invention can be produced by other than the described embodiments, which are presented for purposes of illustration and not limitation, and the present invention is limited only by the claims that follow.
