Description

RELATED APPLICATIONS

This application is a Continuation-In-Part (CIP) of U.S. patent application Ser. No. 077,538 filed on Mar. 11, 2005, which is incorporated by reference herein it its entirety.

FIELD OF THE INVENTION

This application relates generally to a content extractor, and more particularly to a content extractor for containers.

BACKGROUND OF THE INVENTION

Conventional containers come in a variety of configurations (e.g., tubular) to protect the content housed inside the container. For example, flat paper products (e.g., posters, drawings, photographs, blueprints and the like) are typically rolled up and inserted into a tubular container which protects it from damage during shipping and handling.

Rolling up flat paper products to a diameter smaller than the shipping container and then tying the rolled item (e.g. by a rubber band) can make it easier to extract the content from the container. However, using such a tying mechanism can crease or kink the rolled item damaging it within the container. Without a tying mechanism, the rolled item typically unravels within the container to a diameter almost that of the diameter of the container itself. When this occurs, extracting the rolled item from the container is difficult and damage to it often occurs in the process of extraction.

Accordingly, what is needed is a content extractor configured to easily remove content from a container.

SUMMARY OF THE INVENTION

The various embodiments described herein relate to a content extractor. The teachings provided herein solve the earlier mentioned problems and other problems not stated herein.

The present structure provides a content extractor having a retention member with a first surface and a second surface sized to fit into an inner surface of a container. The content extractor includes a pull member having a proximal end and a distal end. The proximal end of the pull member has a pull tab and the distal end of the pull member is configured to securely extend from the retention member. The pull member engages the retention member in slidable communication with the inner surface of the container.

The present structure also provides a content extractor having a first and a second retention member. Each retention member has a first surface and a second surface sized to fit into an inner surface of a container. The content extractor includes a pull member having a proximal end and a distal end. The proximal end of the pull member is configured to securely extend to the first retention member by a pull tab. The distal end of the pull member is configured to securely extend from the second retention member. The pull member engages the first and second retention members in slidable communication with the inner surface of the container.

The present structure also provides a method of forming a content extractor. The method of forming the content extractor includes forming a retention member having a first surface and a second surface sized to fit into an inner surface of a container. The method of forming a content extractor further includes forming a pull member having a proximal end and a distal end. The proximal end of the pull member includes a pull tab and the distal end of the pull member is configured to securely extend from the retention member. By positioning the pull member to engage the retention member, the pull member engages the retention member in slidable communication with the inner surface of the container.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various embodiments. It will be apparent, however, to one skilled in the art that the various embodiments may be practiced without some of these specific details. The following description and drawings provide examples for illustration, but are not intended in a limiting sense and are not intended to provide an exhaustive treatment of all possible implementations.

It should be noted that references to “an”, “one”, or “various” embodiments in this disclosure are not necessarily to the same embodiment, and such references contemplate more than one embodiment. Additionally, reference to “at least one” includes one or more (e.g., 1, 2, 3, 4, etc.). Such reference contemplates one, and only one. Such reference also contemplates more than one. When such reference is made, reference to “independently” contemplates any one or more of the “at least one” having the contemplated limitation. Additionally, when “at least one” of the referenced item “independently” includes a limitation, any one of the referenced items can be the same or can be different, compared to the other referenced item(s), provided that referenced item includes the contemplated limitation.

A content extractor includes a retention member having a first surface and a second surface sized to fit into an inner surface of a container. The content extractor further includes a pull member having a proximal end and a distal end. The proximal end of the pull member includes a pull tab and the distal end of the pull member is configured to extend from the retention member. When in use, the pull tab is closest to the user and the retention member is further from the user, respectively.

Generally, the content extractor can be inserted into the container by handling the pull tab at the proximal end of the pull member and inserting the retention member secured at the distal end of the pull member into the opening of a container. The retention member slidably communicates with the inner surface of the container until the base of the retention member is located at one end of the container (e.g., closed end) and the pull tab is located at the other end of the container (e.g. opened end). Content (e.g., flat paper products) can be rolled and inserted over the pull member securely resting on the retention member inside the container. A cap can be placed over the container covering the pull tab ready for extraction by the user.

Alternatively, content (e.g., flat paper products) can be rolled and inserted over the proximal end of the pull member configured to securely extend from the second retention member. The content slides over the pull member where one end of the content fits onto the second retention member. A first retention member is placed over the proximal end of the pull member fitted about the other end of the content. A pull tab is secured onto the proximal end of the pull member locking the first retention member and securing the content between the first and second retention members of the content extractor.

The content extractor together with the content can be inserted into the container by handling the pull tab at the proximal end of the pull member and inserting the second retention member secured at the distal end of the pull member into the opening of a container. The first and second retention members slidably communicate with the inner surface of the container until the base of the second retention member is located at one end of the container (e.g. closed end) and the first retention member secured by the pull tab is located at the other end of the container (e.g., open end).

Generally, the content of the container (e.g., flat paper products) can be extracted from a container by pulling the pull tab at the proximal end of the pull member. The pull member engages the first and second retention members at the proximal and distal ends of the pull member in slidable communication with the inner surface of the container until the content is extracted from the container.

The invention includes a method of manufacturing a content extractor 1. The method includes forming a retention member 3 having a first surface 5 and a second surface 7 sized to fit into an inner surface 15 of a container 17. The method of manufacturing the content extractor 1 also includes forming a pull member 9 having a proximal end 11 and a distal end 13. The proximal end 11 of the pull member 9 includes a pull tab 19. The distal end 13 of the pull member 9 is configured to securely extend from the retention member 3.

The retention member 3 and the pull member 9 of the content extractor 1 can be manufactured by any method practiced by those of skill in the art. One such manufacturing process utilizes an injection molding process as described in U.S. Pat. No. 5,047,183 and U.S. Pat. No. 4,381,272, that is hereby incorporated by reference.

With respect to the injection molding process, polymer material is introduced into an injection molding machine via a hopper. The injection molding machine includes a heated barrel equipped with a reciprocating screw (driven by a hydraulic or electric motor) that feeds the molten polymer into a temperature controlled mold (e.g., a split mold) by a channel system of gates and runners. The screw melts (plasticises) the polymer and provides additional heating by virtue of the shearing action on the polymer. The screw also acts as a ram by the axial movement of the screw during the injection phase of the melt. To prevent melt backflow during the injection process, a non-return valve is typically disposed at the end of the screw.

The melt is injected into the cavity of the injection molding tool and then a gas (e.g., nitrogen) is injected into the mold at a higher pressure than the material injection pressure forming a gas bubble inside the material. As the melt cools, the pressurized gas presses against the cavity walls making the surface of the pull member 9 and the retention member 3 of the content extractor 1 free from dimensional variations.

Variations of the injection molding process include multi-shot (or 2K molding) where different materials are injected into the same mold, insert molding where metal components are incorporated and structural foam molding where the melt material is foamed to reduce density.

Another such manufacturing process to form the retention member 3 and the pull member 9 of the content extractor 1 utilizes a vacuum thermoforming process as described in U.S. Pat. No. 4,061,706 and U.S. Pat. No. 3,632,272 that is hereby incorporated by reference.

With respect to the vacuum thermoforming process, thermoplastic material in the form of a continuous sheet or as individually cut blanks is heated to a desired temperature and stretched until it is pliable to be advanced over a mold cavity plate creating a seal. The sheet is then pressed against the mold (e.g., by pressurized air). Application of a vacuum and/or a positive pressure on the opposite side of the mold cavity through venting holes in the mold draws the sheet material into the mold cavity until it takes on the shape of the mold. The mold is cooled until the plastic reaches a desired curing temperature. When the curing temperature is reached and the piece is formed, the molded plastic is removed from the mold for further cooling. In one application, air blows back into the mold through venting holes and separates the retention member 3 and the pull member 9 of the content extractor 1 from the mold.

In one embodiment, the retention member 3 and the pull member 9 of the content extractor 1 is formed from metal (e.g., sheet metal) by numerous types and styles of presses for performing metal-working procedures. One such manufacturing process to form the retention member 3 and the pull member 9 of the content extractor 1 utilizes a press process as described in U.S. Pat. No. 4,321,819 that is hereby incorporated by reference.

In most presses, a pair of upper and lower die members is moved into a cooperating relationship with each other by a hydraulic or mechanically actuated device. The lower die usually is mounted on a stationary bed and the upper die is mounted on a vertically movable ram or slide. Large forces are exerted on a press frame when the dies engage with each other during the metal-working operation to form the components of the content extractor 1.
