Benefits of technology

[0009] It is a feature of the present dispenser to define a pathway which is easily accessed throughout.
[0019] It is yet another advantage of the foregoing feature that the components may be rotated to a convenient rotational position for opening and closing (sealing) the dispenser.

Problems solved by technology

Even when in a closed position, thereby sealing the container, the cap can often be easily rotated, thereby compromising the seal.
These rotatable caps are also less desirable to consumers because they are not uniformly oriented in display cases.
Hence, rotatable caps may also be less desirable functionally because dispensers with different orientations usually cannot be opened and closed with repeated similar manual motions.
These easily rotatable caps also usually lack any other structure further promoting an airtight seal.
While these dispensers have the advantage of usually not requiring a separate cap, they are subject to clogging when materials left in the dispenser pathways are partially dried.

first embodiment

[0054] Suitable materials for the present dispenser include polyethylene, e.g., high density polyethylene, and polypropylene. However, other suitable materials can be found in the Handbook of Plastics, Elastomers, and Composites, Third Edition, Charles A. Harper, Editor-in-Chief, McGraw-Hill, New York (1996), the entire disclosure of which is hereby incorporated by reference. Individual components of the present dispenser may be formed by processes such as injection molding utilizing the foregoing materials.

[0055] The first embodiment of present dispenser is assembled by extending the first member 104 through the base collar opening 122 until the flange upper surface 156 contacts the base collar lower surface 120 and the tabs 124 are accommodated in the flange slots 154. The second member 106 is forced into position, wherein the upper extension 152 is accommodated within the bore 222 and the second member tabs 210 are accommodated in the first member slots 180. The cap 108 is closed...

second embodiment

[0066] Suitable materials for the present dispenser include polyethylene, e.g., high density polyethylene, and polypropylene. In one situation, the collar 302 is made from high density polyethylene and the cap 308 and cone 304 are made from polypropylene. However, other suitable materials can be found in the Handbook of Plastics, Elastomers, and Composites, Third Edition, Charles A. Harper, Editor-in-Chief, McGraw-Hill, New York (1996), previously incorporated by reference. Individual components of the present dispenser may be formed by processes such as injection molding utilizing the foregoing materials.

[0067] As best seen in FIGS. 20 and 21, the second embodiment of present dispenser is assembled by extending the first member 304 through the base collar opening 322 until the flange upper surface 356 contacts the base collar lower surface 320 and until the collar upper member 312 is disposed in the slot 362. The second member 306 is forced into position, wherein the upper extensio...

Abstract

The present dispenser tip attaches to a container and may include a separately formed base, first and second member, and cap. The base may be threadably attached to the container. The first member may include a flange, a basal portion and an extension. The flange may engage an inner surface of the base. The basal portion and the extension may engage to define a pathway for a flowable material being dispensed from the container. The second member may be disposed about the extension and may be connected to the cap by a hinge. The cap may include a stopper element and a rib or groove to seal the dispenser when the cap is in a closed position.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] This is a continuation-in-part of U.S. patent application Ser. No. 10 / 686,182, filed 15 Oct. 2003, which, in turn, claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 60 / 497,585, filed 25 Aug. 2003, each hereby incorporated by reference.BACKGROUND [0002] 1. Field of the Invention [0003] This invention relates to dispensers and, in particular, this invention relates to devices which are attachable to containers for dispensing a substantially flowable material urged from the containers, and which can be resealed between uses. [0004] 2. Background [0005] Containers for many flowable materials, such as glue and other adhesives, must often be sealed between uses and must further aid in dispensing the flowable materials onto surfaces in desired amounts. To this end, these containers often include a resealable dispenser which is threadably attached to a container. To be resealed, these dispensers often have a cap atta...
