Description
212111' _1_ COMBINATION BOTTLE AND STICK
Field of Invention This invention relates to a combination bottle container and stick container/dispenser. In particular, this invention relates to a bottle container having a cavity for releasably retaining the stick type container/dispenser.
Backeround of Invention Many liquid or semi-liquid products, such as glues, hand lotions, shampoos, are bottled in plastic containers or bottles. Plastic provides a lightweight inexpensive method of marketing a product. Plastic bottles come in a variety of sizes and shapes, from cylindrical to oval to rectangular.
Many other products, such as glues, cosmetics, lipsticks and lip balms and antiperspirants, are contained within a tube or stick type container or dispenser. The stick container will advance the product out of the container as the consumer uses the product. Such stick dispenser/container is described in United States Patent No. 3,912,403.
For many marketing reasons, it is desirable to package and sell two compatible products together. However, due to the incompatible shape of the stick dispenser/container, a stick dispenser cannot be packaged with a bottled product without adding a cardboard container.
Alternatively, the two products could be wrapped in a clear plastic or cellophane wrapper and shrink-wrapped together or bonded together with a 21~111'~
_ _2_ strap or tape. However, such a product would occupy excessive amount of shelf space and difftcult to align neatly. As a result, retailers would not want to carry such products.
Further, once the consumer has unwrapped the package, the two products may become separated and any advantage for purchasing the two compatible products is lost.
In United States Patent No. 5,065,875, there is disclosed a bottle and stick dispenser combination. The bottle has a cavity in a face for nesting the stick dispenser. The bottle has retaining means for releasably retaining the dispenser within the cavity in a snap or frictional fit.
The bottle and stick dispenser combination of United States Patent No. 5,065,875 may provide a suitable marketing vehicle. However since the cavity occupies one face of the bottle, the stick dispenser must be nested within either the front face or the rear face of the product. If the stick dispenser is nested on the front face, there is very little room left for labelling the product. If the stick dispenser is nested on the rear face, the consumer will not see the uniqueness of the product when it sits on the retail shelf.
It has also been found that the molded undercut retaining means of the bottle according to the co-pending application does not provide a high degree of gripping force. The gripping force can be increased by increasing the length of the molded undercut surface. However, increasing the length of the undercut surface presents serious molding problems, making molding more difficult with a higher rate of defective products being molded.
212111' _3_ Summary of the Invention The disadvantages of the prior art may be overcome by providing a bottle with a molded cavity in the side of the bottle for releasably retaining a stick type container/dispenser.
According to one aspect of the invention, there is provided in combination, a molded bottle and a stick dispenser wherein the bottle comprises front and rear faces and side edges. One of the side edges has a cavity for nesting the stick dispenser. The stick dispenser has end surfaces and the cavity has end surfaces. Each of the end surfaces of the stick dispenser has a recess and each of the ends of the cavity has a domed surface. The domed surfaces are sized and spaced to receive each of the recesses of the stick dispenser in a snap fit.

Description of the Invention The present invention is generally illustrated as 10 in Figure 1. The invention includes a bottle 12 and a stick dispenser 14.
Referring to Figure 2, bottle 12 has a cavity 16 which extends inwardly from a side edge 8. The cavity extends in a longitudinal direction of the bottle 12. The cavity 16 has an opening sized to receive and nest the stick dispenser 14. Bottle 12 may be any desirable shape, including cylindrical.
The edge of the cavity 16 has at least two flanges 18 and 20 on opposite sides thereof. The flanges 18 and 20 extend from a rear face 22 and front face 24 of the bottle, respectively. The inner faces 26 of flanges 18 and 20 are curved to cradle the stick dispenser 14.
~~.~11~.7 - -s-The top and bottom ends of cavity 16 have domed surfaces 28 and 30. The domed surfaces are spaced inwardly from the inner face 26 and the front and rear faces 22 and 24.
The stick dispenser 14 can be any type of dispenser known in the art. The stick dispenser 14 has a tubular body having a cap 32 at one end and a rotatable end 34. The rotatable end 34 is the means for advancing or dispensing the material housed within dispenser 14.
The cap 32 has a recess 33 formed in top surface 36. Similarly, the rotatable end 34 has a recess 35 in the bottom end of the dispenser 14. Domed surfaces 28 and 30 are sized to complementarily engage the recesses 33 and 35 of the dispenser 14.
Cavity 16 is sized to snappingly fit the dispenser 14 into the cavity 16. A first end of dispenser is presented over a first domed surface, while the second end is levered towards the second domed surface. The second end of the dispenser will frictionally engage the second domed surface. The dispenser is urged beyond the frictional engagement until the dispenser is snappingly engaged by the bottle. To remove the dispenser, the steps are reversed.
The shape of dispenser 14 is preferably tubular but could be any shape provided the cavity 16 is shaped to nest the stick dispenser 14 and flanges 18 and 20 will cradle the stick dispenser 14.
In the first embodiment of the invention as illustrated in Figure 1, the stick dispenser 14 will extend outwardly of the bottle. The cap 32 and the ~12~~.17 .. -6-rotatable end 34 will be exposed to allow the dispenser to be easily gripped for removal. This arrangement also has the advantage that the size of cavity 16 is minimized increasing the volume of the bottle 12.
In the second embodiment of the invention as illustrated in Figure 5, the dispenser is flush with the front and rear faces of the bottle presenting a very smooth appearance.
In the third embodiment of the invention as illustrated in Figure 6, flanges 18 and 20 are replaced by a plurality of offset flanges 118, 119 and extending from opposite sides of the cavity 16. The flanges 118, 119 and 120 will cradle the dispenser 14. More importantly, flanges 118, 119 and 120 are easier to mold than flanges 18 and 20 because the amount of undercut in the mold is minimized.
To manufacture a bottle 12, a blow molding process is used. Molds having a shape complementary to the shape of bottle 12 are manufactured in two half molds. The molds must be undercut to some extent in order to mold flanges 18 and 20. The undercut should not be excessive otherwise the bottle will not be removable from a single piece half mold. If the undercut is to be greater, then the molds will be required to be manufactured in multiple pieces to permit removal of the finished bottle.
Bottle 12 may be blow molded using any suitable polymer material.
The preferred materials are olefins, and in particular polyethylene.
Polyethylene is ideally suited for blow molding to produce a semi-rigid bottle.
