A rigid cradle (3) is inserted into the slotted opening and secured to a section by a retaining flange (13). The rigid cradle has a shape that will contain a sample container (1). The container containing a flowable substance is inserted into the cradle and the sections are folded along the foldlines as to encapture the container between the cradle and a section.

Description: BACKGROUND AND OBJECTS OF THE INVENTION 1. Field of the Invention The present invention relates to a postcard-type package for flowable substances and the like and, more specifically, to a new configuration for a mailable package which contains a container with a quantity of flowable product normally called for in sampling. 2. Description of the Prior Art Various attempts have heretofore been made to provide a mailable package for fragile items. The US-A-2,646,876 discloses a mailable display package to hold an article for shipment which uses a thick boxboard to form the structure and employs a series of flaps to seal the package. A drawback of this package is the requirement for a thick boxboard that increases the weight of the shipping container, increases the size of the total package and increases the material costs. A further drawback of the boxboard is an increased difficulty in producing the boxboard with the required cut-outs and creases which results in increased production costs. A still further drawback is the increased production costs involved with producing the large number of flaps. US-A-4,240,547 discloses a compact, reusable specimen mailer to safely ship fragile specimens. It uses a polystyrene plastic foam to form the structure and employs an absorbent material around the specimen containers. US-A-4,777,964 discloses a blood sampling kit and a method of use which uses a base member and a backing to serve as a floor portion for blood vials. It further contains an alcohol swab, a finger-pricking element and clay. In addition, it employs a separate masked envelope to send the samples safely via the postal service. 3. Objects of the invention It is therefore an object of this invention to provide a new and improved postcard-type package for shipping sample containers via the postal service. Another object of this invention is to provide a new and improved postcard-type package for shipping sample containers which overcomes the aforesaid drawbacks of the 876 patent, i.e., requirement for a boxboard. Another object of this invention is to provide a new and improved postcard-type package for shipping sample containers which is easy and inexpensive to produce and assemble. Another object of this invention is to provide a new and improved postcard-type package for shipping sample containers via the postal service which involves minimum shipping costs due to the size and weight of the shipping package. Another object of this invention is to provide a new and improved postcard-type package for shipping sample containers via the postal service which safely retains a fragile container while allowing the receiver of the postcard-type package to open the package and easily remove the sample container from the cradle. Another object of this invention is to provide a new and improved postcard-type package for shipping sample containers involving a cradle comprising one or more clasps protruding from the surface of the cradle for retaining the container. A further object of this invention is to provide a new and improved postcard-type package for shipping sample containers which visibly displays the sample container when the package is sealed in order to maximize the sample container's visibility at the receiving point. A still further object of this invention is to provide a new and improved postcard-type package which contains a rip-off business postcard in order to allow a sender to receive a reply. Objects and advantages of the invention are set forth in part herein and in part will be obvious therefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims. SUMMARY OF THE INVENTION The present invention is directed to a new and improved postcard-type package for flowable substances which may be used for shipping sample containers via the postal service employing a low cost sheet, such as a single-ply cardboard, and a cradle which may be composed of a plastic type material. The cardboard sheet is inexpensively produced requiring only one or more foldlines and a slotted opening. In a preferred embodiment, the postcard-type package comprises a relatively stiff flat sheet having a creased centerline forming a first and second section, a slotted opening cut in the second section and a cradle. The cradle comprises a rigid material shaped in such way that the cradle retains a container. The cradle is inserted into the slotted opening and secured by a flange to the second section. The container containing a flowable substance is inserted into the cradle. The container is a sample vial with a stopper. A sealing means, preferably comprising tape or glue, is employed to hold the folded first and second sections securely together. A preferred cradle is composed of a non-opaque material that allows the container to be seen through the cradle. Further, the container includes a label. A preferred container contains a sample quantity of a fragrance for advertising purposes. The cradle has a means for retaining the container. The retaining means is designed to maintain the container in the cradle whereby the container's movement is sufficiently restricted in order to substantially reduce the possibility that the container will be damaged during shipping of the postcard-type package. At the same time, the retaining means is designed to allow the receiver to easily remove the container from cradle. An example of the ease of removing the container from the cradle entails the receiver opening the postcard-type package and applying a removal force in order to separate the container from the cradle. Such removal force may consist of using a fingernail to pick out the container from the cradle. An example of the retaining means consist of one or more molded clasps that are an integral part of the cradle protruding out from the inside. Alternatively, one or more clasps are separate pieces that are fastened directly to the inside surface of the cradle. In a preferred embodiment, the first section is a business reply card to enable the receiver to simply, easily and at no expense, communicate directly with the sender. Preferably, the sections are folded along the crease to enable direct contact with each other, thus, forming a sealed package to enable the container to be safely shipped without further restraining devices. As used herein, the term "foldlines" are intended to encompass a single straight line extending completely across the relatively stiff flat sheet formed by a scored continuous line. It will be apparent from the foregoing general description that the objects of the invention specifically enumerated herein are accomplished by the present invention. Thus, it has been found that a postcard-type package can be constructed more economically utilizing thin gauge materials than those utilized to construct prior packages containing sample containers. In addition, it has been found that production and assembly of a package can be substantially reduced at the same time the likelihood of damage to the container can be eliminated by utilizing the invention. Moreover, it has been found that the invention increases the advertising visibility of the product by displaying the container. It will be understood that the foregoing general description and the following detailed description are exemplary and explanatory of the invention but are not restrictive thereof. The accompanying drawings, referred to herein and constituting a part hereof, illustrate preferred embodiments of the present invention, and together with the description serve to explain the invention. BRIEF DESCRIPTION OF THE DRAWINGS FIGS. 1A, 1B and 1C are a perspective view of alternative embodiments of a postcard-type package in its opened condition, the view showing the placement of the container into the cradle and of the cradle into the slotted-opening of the relatively stiff substantially flat sheet containing foldlines. FIG. 2A is a front angled perspective view of the postcard-type package shown in FIG. 1, this view illustrating the package in its closed condition for shipping and showing the visibility of the container. FIGS. 2B and 2C are side perspective views of the postcard-type package shown in FIG. 2A. FIGS. 3A, 3B and 3C are perspective views of the cradle. FIG. 3A is a top perspective view. FIG. 3B is a fragmentary view illustrating the clasps. FIG. 3C is a side perspective view. DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now more particularly to FIGS. 1A, 2A, 2B and 2C of the accompanying drawings, there is illustrated a postcard-type package constructed in accordance with the preferred embodiment of the present invention. As here embodied, the invention includes a relatively stiff substantially flat sheet divided by a creased foldline 7 advantageously into two equal sized sections, 5 and 6. Section 6 is provided with a slotted opening 4 where a cradle 3 is in direct contact with section 6 by flange 13. Container 1 has a removable opening 2 and is mounted directly into cradle 3. Preferably, the relatively stiff substantially flat sheet is made up of a single-ply cardboard, the cradle 3 is made up of polystyrene or polyester or a copolymer thereof, and the container 1 is made of glass or plastic which may depend upon the nature of the contents and the material costs. It will be seen from the foregoing that the structure of FIGS. 1A and 2A forms an enclosed chamber between section 5 and cradle 3, in which container 1 is held. This is accomplished by folding sections 5 and 6 along the creased foldline 7 in the direction shown in FIG. 1A until sections 5 and 6 contact each other. As seen in FIG. 2A, folded sections 5 and 6 form a package and are secured by seal 15 and/or adhesive 16. In this sealed form, container 1 is visible but enclosed within cradle 3. In addition, as shown in FIG. 2A, section 5 has space for mailing label 17 and postage 14. FIGS. 2B and 2C further show side views of the folded postcard-type package. Referring more particularly to the preferred embodiment, FIG. 1A, section 5 contains a printed communication in the form of a business reply card. After receiving the folded postcard-type package in the form shown in FIG. 2, the postcard-type package can be unfolded and section 5 can be separated from section 6 at foldline 7 and section 5 can be returned to the sender. FIG. 1B illustrates a further advantageous arrangement for a postcard-type package containing sections 5, 8 and 9 that are one or more business reply cards which can be separated along foldline 7. FIG. 1C illustrates a still further advantageous arrangement for a postcard-type package containing sections 5, 10 and 11 that are one or more business reply cards and/or packettes 12 containing a flowable substance which can be separated along foldline 7. Packettes 12 are shaped to fit securely in the postcard-type package and are preferably made up of burst-proof packettes. Perspective views of cradle 3 are shown in FIGS. 3A, 3B and 3C. In a preferred embodiment, cradle 3 is provided with one or more clasps 18 protruding from the surface of cradle 3 for retaining container 1. As illustrated in FIG. 3B, clasp 18 is located around the inside circumference of the cradle. As can be seen in FIG. 3C, clasp 18 can consist of a separate curvilinear piece attached to the inner surface of the cradle or can be molded clasps that are an integral part of the cradle protruding out from the inner surface of cradle 3. To the extent not already indicated, it also will be understood by those of ordinary skill in the art that any one of the various specific embodiments herein described and illustrated may be further modified to incorporate features shown in other of the specific embodiments, as desired. The invention in its broader aspects therefore is not limited to the specific embodiments herein shown and described but departures may be made therefrom within the scope of the accompanying claims, without departing from the principles of the invention and without sacrificing its chief advantages.
