Abstract: A valve component utilized in a fluid end assembly of a reciprocating pump may contain a multi-piece construction. The valve component may include a valve body portion, a leg assembly portion, a sealing element, and an insert at least partially captured between the valve body portion and the leg assembly portion. The insert may be constructed from a carbide or a ceramic material, and, when the valve component is fully assembled, may be compressed between the valve body portion and the leg assembly portion. The insert may at least partially form the strike surface of the valve component. The valve body portion and the leg assembly portion may both be constructed from a metallic material, and the valve body portion may define a sealing seat. The sealing element may be constructed from an elastomeric material that may be pre-formed and then compression molded onto the seat of the valve body.

Abstract: A valve component utilized in a fluid end assembly of a high pressure reciprocating pump includes a valve body and a sealing element. The valve body defines a recess configured to receive the sealing element. The sealing element is composed of a fiber reinforced material. The valve component is configured to be disposed in a closed position with respect to a valve seat such that a sealing surface of the sealing element engages with a corresponding sealing surface of the valve seat in the closed position.

Abstract: The present invention relates to a method for producing a squeeze tube with maximal surface area labeling and a tube produced thereby.

Abstract: The present invention features pressure-sensitive labels produced from unidirectional heat shrinkable polyethylene films and their application to consumer products such as containers, tubes, bottles and batteries.

Abstract: The present invention provides an adhesive label in which a consumer item or device, such as a battery tester strip is printed in web form and is bonded to a consumer package.

Abstract: The present invention involves containers and their method of manufacture. More specifically the invention relates a preprinted, unsupported, thin-film label for direct application to a container. The invention also provides a system and method for applying a thin-film label to the container surface.

Abstract: The present invention is a molded container head with an orifice valve contiguously molded from a single piece of material. The instant container head assembly is an improvement over existing orifice valves as it can be formed during the molding of the container or container cap.

Abstract: The present invention relates to a method for producing a squeeze tube with maximal surface area labeling and a tube produced thereby.

Abstract: The present invention relates to an improved method of labeling squeeze tubes. The method involves adhering a label to a tube, which is optionally treated under conditions which achieve a dyne level of at least 38, so that the label adheres to the tube. Upon sealing of the tube to generate the squeeze tube, the label covers the sealed area thereby maximizing the labeled area of the squeeze tube.

Abstract: The present invention is an invisible eyemark for orienting squeeze tubes during manufacture. The invisible eyemark is composed of a dye that absorbs electromagnetic wavelengths outside of the visible spectrum and is therefore invisible to the human eye. The invisible eyemark is an improvement over the art, as it does not detract from tube decorations or product labels.
