Cradle for retaining a container

Abstract: The invention relates to a cradle (3) for retaining a container (1) comprising a shape substantially corresponding to said container and dimensions sufficient to enable said container to fit within said cradle and means (18) for retaining said container in said cradle.

Description: The invention relates to a rigid cradle for retaining a fragile container during shipping which is usable in a postcard type package for flowable substances according to the first part of claim 1. Various attempts have heretofore been made to provide a mailable package for fragile items. The Sparks U.S. Patent No. 2,646,876 (hereinafter the 876 patent) 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 the 876 patent is a 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 of the 876 patent is the increased production costs involved with producing the large number of flaps. The Taylor U.S. Patent No. 4,240,547 (hereinafter the 547 patent) 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. The Briggs U.S. Patent No. 4,777,964 (hereinafter the 964 patent) 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, the 964 patent employs a separate masked envelope, Fig. 2, to send the samples safely via the postal service. From DE-A-2916564 a cradle according to the first part of the main claim is known. It is an object of this invention to provide a cradle which is usable in a postcard-type package for shipping sample containers via the postal service. Another object of this invention is to provide a cradle for a 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. A further object of this invention is to provide a cradle for a 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. The cradle which solves the above referenced objects is defined in claim 1. Preferred embodiments of claim 1 are defined in the subclaims. The cradle according to the invention is usable in an 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. 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. A preferred 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. It will be apparent from the foregoing general description that the objects of the invention specifically enumerated herein are accomplished by the present invention. In addition, it has been found that production and assembly of a package can be substantially reduced at the same time the liklihood of damage to the container can be eliminated by utilizing the invention. Moreover, it has been found that the invention increases the advertising visiblility 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 Fig. 1 is a prespective view 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. 2 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. 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. Referring now more particularly to Figs. 1 and 2 of the accompanying drawings, there is illustrated a postcard-type package constructed with a cradle according to the present invention. As here embodied, the postcard-type package 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 the 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 carboard, 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. 1 and 2 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. 1 until sections 5 and 6 contact each other. As seen in Fig 2, 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. 2, section 5 has space for mailing label 17 and postage 14. Perspective views of cradle 3 are shown in Figs. 3A, 3B and 3C. 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.
