Benefits of technology

The invention is a seal plug that can be easily included in a fluid-filled container and reused to reseal the container. The seal plug has a conical shape that fits snugly with the container body, and a gripping member that helps guide the seal plug into position. The seal plug can be easily removed using a pull tab, which is designed to be easily gripped by a user. The container also includes a dispensing cap with a sealing arrangement that ensures a tight seal and prevents leakage or contamination during use. The technical effects of the invention are improved sealing, ease of use, and reduced plastic content.

Problems solved by technology

The risk when using such services of leakage of the container via the cap is greater, as handling of the individual containers can more easily result in the packaging being in a non-upright orientation than were the container to be bulk-delivered to a retail outlet.

first embodiment

[0034]Turning to FIG. 3, this illustrates an assembly including transit plug shown in FIGS. 1 and 2. The assembly comprises a container body 30 with a disc-top dispensing cap 31 secured by a threaded connection 32 thereto. In order to provide a transit seal therebetween a transit plug 33 is included which can be removed by a user on first use of the product. The lower flange face 34 of the flange 35 of the transit plug 33, sealingly engages the rim 36 of the neck 37 of the container body 30. The upper flange face 38 is sealingly engaged with the circumferentially deployed flexible leaf seal 39. In order to hold the dispensing cap 31 and the transit plug 33 together, the cross-shaped spigot 40 engages the dispensing conduit 41 of the dispensing cap 31. A pull tab 42 is provided to enable a user to separate the transit plug 33 from the dispensing cap 31.

second embodiment

[0035]FIG. 4 illustrates transit plug 50 for use with a flip-top dispensing cap 51. In this embodiment, engagement of the transit plug 50 with the container body 52 through the flange faces is as described above for the embodiment of FIG. 3, as is the pull tab 53. In this embodiment the transit plug 50 has an upstanding tubular feature 54. This tubular feature 54 defines a cylindrical space, and makes frictional contact on its inside diameter wall with the outside diameter wall of the dispensing cap orifice detail 55. Frictional contact ensures that the transit plug 50 is retained to the cap.

third embodiment

[0036]In FIG. 5, transit plug 70 for use with a flip-top dispensing cap 71. In this embodiment, engagement of the transit plug 70 with the container body 72 through the flange faces is as described above for the embodiment of FIG. 3, as is the pull tab 73. The dispensing cap 71 includes a tubular section beneath the dispensing conduit detail 74. The transit plug has an upstanding spigot feature 75. The spigot feature 75 forms an interference fit with the dispensing cap tubular section 74 on the inside diameter face. The spigot feature 75 has a cross-shaped or plus sign cross-section, which enables sufficient frictional engagement with the tubular section of the cap 71, but reduces the mass of the spigot 75 and the materials required for its production. Other shapes of spigot can also be utilised such as solid or hollow cylindrical, or other polyhedra.

Abstract

The current invention discloses a transit seal plug, the seal plug to be releasably secured to a dispensing cap. The sealing member includes first and second annular sealing faces, and further also includes a gripping member which extends away from a first side of the sealing member to engage walls of a conduit. A pull tab extends from the opposite side of the sealing member, to facilitate removal of the seal plug from a dispensing cap.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority to United Kingdom Patent Application No. 2015197.3, filed on Sep. 25, 2020, including the specification, claims, and drawings, the entire disclosures of which are incorporated by reference herein.FIELD OF THE INVENTION[0002]The present invention relates to a plug which prevents leakage of materials from a container during transit of the container. The type of container particularly contemplated is a plastic container having a disc-top or a flip-top dispensing cap, of the type commonly used to contain liquid products intended, for example, for household, personal, pet, automotive care.BACKGROUND OF THE INVENTION[0003]The use of plastic containers to transport fluids used in the consumer care sector is ubiquitous. Products such as personal cleaning, household, car-care etc. are typically supplied in a container body made from a plastics material. In order to dispense a small volume of the liquid, a dispen...
