The second bottle can be frictionally inserted into an opening in the middle of the first bottle during normal storage and separated from the first bottle for mixing before actual application of the stored products. In one embodiment, the package comprises a first bottle to contain a liquid product and the second bottle to contain a concentrate refill of the first product. In another embodiment, the package comprises a first bottle to contain the first product, and a second bottle to contain a second product to be mixed with the first product before actual application of the mixture.

RELATED APPLICATIONS

This utility patent application is related to U.S. Design application Ser. No. 29/547,311 filed Dec. 2, 2015 entitled “Two Bottle Container Package”, which application is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to a container package or assembly having two bottles allowing separate storage and/or mixing of products, and more particularly to an improved storage container having a smaller bottle that can be inserted into an opening of a larger bottle.

BACKGROUND OF THE INVENTION

A wide variety of plastic material bottles are used for storing and dispensing a wide variety of chemical products such as cleaning liquids or pesticide. For applications where a concentrate solution can be housed within a smaller container and housed within the larger, ready-to-use container, or where two components must be isolated from each other before being mixed to form a ready-to-use preparation, packaging or assembly with two plastic bottles are used or envisaged. For example, U.S. Pat. No. 3,443,726 disclosed a container consisting of two container sections which are threadably engaged and are designed to be screwed into one another. This container however can only be handled as a single unit because the upper container section is only closed by insertion of the lower bottle/section with a stopper in between to prevent the mixing of the contents. U.S. Pat. No. 4,823,946 discloses an improved two-compartment container consisting of two separately Tillable bottles designed to be fitted together one above the other through an intermediate component. Although this two-compartment container can be filled and sealed independently of one another and can be stored, handled and supplied separately from and independently of one another as filled individual components, the intermediate connecting component requires a large pitch thread on the neck of the second bottle for it to be easy to use. U.S. Pat. No. 5,277,303 disclosed a two bottle packaging that further improves the intermediate connecting component of the two-compartment container of U.S. Pat. No. 4,823,946 so that the lower bottle can be made of glass instead of only plastic due to the large pitch thread required in U.S. Pat. No. 4,823,946.

All of the above two bottle packaging or assembly, however, still require complicated connecting or linking means to keep the two bottles together.

SUMMARY OF THE INVENTION

According to certain aspects, the present invention provides a two-bottle container package design that solves the above identified problem. The container package or assembly of the present invention comprises a first bottle and a second bottle, wherein the second bottle can be frictionally inserted into the first bottle. The first bottle is dimensioned to have an opening in the middle of the body that defines an open space and a handle. The second bottle is smaller than the first bottle and dimensioned so that the second bottle can be frictionally inserted into and removed from the opening of the first bottle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

This application discloses a container package or assembly design that has two separable bottles of different sizes. The smaller bottle of the container design can be frictionally inserted into and removed from an opening of the larger bottle. The disclosed solution has the following advantages over the existing two-bottle package.

First, by having the smaller bottle frictionally inserted into the opening of the larger bottle, the disclosed solution does not require any additional component to keep the two bottles together thus makes it as economical as possible to manufacture. Second, this solution also saves a customer the trouble having to actually measure the contents of the two bottles to get the mixing ratio right, since the cap of the smaller and/or larger bottler of the body or the bottles themselves may be marked, sized or otherwise configured to provide a guide for specific measurement of concentrated solution to be added to the larger bottle for refill purposes, thereby eliminating the need for an independent means of measurement. Third, the nested design also saves shelf space because it takes the shelf space of one bottle as opposed two.

FIG. 1shows the larger bottle100and the smaller bottle200of a two-bottle assembly10according to an embodiment of the present invention. The two-bottle assembly is also referred to as “container package” in the specification and claims. As shown, bottle100has a top opening110for filling or dispensing of a first material and a cap120for closure. Bottle100has an opening130in the middle of the body that also defines a handle140. As shown, bottle200also has a top opening210for filling and dispensing a second material and a cap220for closure. Note that the first material to be dispensed and the second material to be dispensed may be the same material or different materials. For clarity, the bottle100and bottle200are shown as empty bottles without the first material or second material stored in them.

FIG. 2depicts how the two-bottle assembly10looks like when bottle200is fully inserted into the opening of the110of bottle100.

As shown in bothFIGS. 1 and 2, both bottle100and bottle200have round top openings with round cap120and round cap220. It should be noted however, that the top openings of the two bottles may have a geometric shape other than round. For example, the openings can be oval. It should also be noted that the top openings of the two bottles do not need to have the same shape.

In some embodiments, cap120and cap220may be plastic screw caps. According to another embodiment, cap120and cap220may be a flip-top.

In some embodiments, cap120and cap220may be completely removable from bottle100and bottle200respectively. In other embodiments, cap120and cap220may be connected to bottle100and bottle200through a thin plastic band to avoid getting lost.

In some embodiments, instead of a regular cap120as depicted inFIG. 1, bottle100may use a generic sprayer attachment for spraying the content therein. The generic spraying attachment is not shown in the drawings for clarity, but an example of a generic spraying attachment is shown as element 20 in FIG. 1 in US Publication No. 2009/0308889, titled, “Container System,” by Lindsay et al. Element 20 is described as a trigger-spray device in US 2009/0308889.

The first bottle may be used to store a first product and the second bottle may be used to store a second product, which needs to be stored separately from the first product. The first product may be in one of the forms consisting of liquid, paste, or solid such as powder or grains. As a non-limiting example, the first product can be an oxidizer in paste form used to mix with an oxidizing chemical in liquid form in the second bottle for purpose of hair coloring.

In some applications, the first bottle may be used to store a first product, and the second bottle may be used to store the concentrate refill of the first product. For example, the first bottle may be used to store dish washing detergent and the second bottle may be used to store the concentrate refill of the dish washing detergent. Once the dish washing detergent in the first bottle is used up, the concentrate refill stored in second bottle can be poured into the first bottle and then just adding water to fill up the first bottle will generate in the first bottle a properly diluted dish washing detergent.

It is preferred that the minimal volume of the smaller bottle is at least as large at the amount of liquid needed for a single usage (i.e., a single load of washing detergent).

In some applications, the smaller bottle, its cap, or body can be marked with concentrate levels and/or dilution rates and can be used as a measuring device as opposed to or in addition to storage.

Turning toFIG. 3, it shows a prospective view of the larger bottle100.

FIG. 4Ais a front view of a first bottle (bottle400) andFIG. 4Bdepicts the corresponding front view of a preferred embodiment of bottle400. As shown inFIG. 4B, the height (410) of bottle400measures about 8.56 inch. The handle of bottle400is curvy on the exterior surface, which curve (420) has a radius of about 12.1 inch. The diameter of the cap (430) is 1.1 inch. The rectangular base of bottle400measures about 5 inch wide (450).

FIG. 4Balso depicts the location of the opening space in the middle of bottle400for the smaller bottle. As shown, the top of the opening space in the middle of the bottle to the base of bottle400is about 6.06 inch (450). The top of the opening is about 1.19 inch in diameter (460). The bottom of the opening is rectangular. The central area of the surface of the bottom of the opening space is also rectangular and slightly raised for about 0.06 inch (480) above the surrounding surface area. The raised rectangular surface of the base is about 1.68 inch wide (470). This raised smaller surface adds the friction needed to keep the smaller bottle in place when inserted. It is noted that bottle400also has a ribbed and/or tapered neck design (490) that is for easy grip when the smaller bottle is inserted in the opening space.

FIG. 5Ais a right side view of the larger bottle that directly shows the exterior surface of the handle (520).FIG. 5Bdepicts the corresponding front view of a preferred embodiment of the larger bottle. As shown, the width of the rectangular base (510) measures about 2.13 inch. The height of the bottle (520) is about 8.56 inch measured from edge of the cap to the base. The diameter of the cap (530) is about 1.1 inch.

FIG. 6is a left side view of the larger bottle600according to a preferred embodiment of the present invention.FIG. 7is a top view of the larger bottle according to a preferred embodiment of the present invention.FIG. 8is the bottom view of the larger bottle.

FIG. 9is a front view of a preferred embodiment of the smaller bottle according to the present invention. As shown, the left exterior surface (910) is curvy having a radius of about 3.2 inch and the right exterior surface (920) is curvy having a radius of about 7.02 inch.

FIG. 10is the right side view and the left side view of a preferred embodiment of the smaller bottle according to the present invention. The height (1010) of the neck is 0.7 inch. The height (1120) of the smaller bottle is 2.32 inch.

In some embodiments, the left side view of the smaller bottle is the same as that of the right side view. In some embodiments, the left side of the smaller bottle may have markings on the surface for measurement purposes.

FIG. 11is the top view of a preferred embodiment of a smaller bottle1100according to the present invention. As shown, the diameter (1110) of the cap measures about 1.10 inch, and the width of the square surface (1120) of top is about 1.29 inch.

FIG. 12is the bottom view of a preferred embodiment of a smaller bottle1200according to the present invention. As shown, the base of bottle1200has a rectangular shape with the outer edge measures about 2.01 inch long and about 1.54 inch wide. In the center, there is an concentric rectangular indent that measures about 1.47 inch long and about 1.02 inch wide. This indented surface is designed to frictionally wrap around the raised surface at the bottom of the opening of the larger bottle as discussed. This design allows additional friction to secure the smaller bottle when inserted.

It should be noted that different materials can be used for making bottles discussed above, such as plastic, glass, metal. However, plastic is the preferred material to use in making these bottles not only because it is economical but also because it is malleable so that the smaller bottle can be frictionally inserted in the opening.

It should also be noted that in the above description, the shape and form of the two bottles is not limited to that as depicted inFIGS. 1-12. The smaller bottle can be of any form or shape as long as it can be frictionally inserted into the opening of the larger bottle. For example, the smaller bottle can be a cube/rectangular/pyramid container inserted into a larger cube/rectangular/pyramid container.

Alternatively, the larger bottle may also have spraying capability. As shown inFIGS. 1-4, the larger bottle has a ribbed and/or tapered neck design for easy grip.
