Abstract
A tubular container 12 for a semi-solid material such as toothpaste, hand cream, food spread, glue or pharmaceutical cream, comprises a neck portion 10, an opening 8 in the neck portion, a closure member for the opening, a body portion, which contains the semi-solid material and squeezable in order to force the semi-solid material through the opening, and a movable, wedge shaped member 14 which is positioned in the body portion and which moves along the body portion from a closed end 16 of the body portion towards the neck opening on squeezing of the container body portion. The movable member forces the semi-solid material in front of itself, thereby facilitating the removal of substantially all the semi-solid material from the tubular container. The member preferably includes a projection 22 which can enter the neck opening 8 (Figure 5), and is preferably deformable and of plastics or rubber. In plan view the member may be more oval shaped. <IMAGE>
Description
A TUBULAR CONTAINER FOR A SEMI-SOLID MATERIAL
This invention relates to a tubular container for a semi-solid material.
Tubular containers for a semi-solid material such for example as toothpaste and handcream are well known.
The semi-solid material is obtained by squeezing the tubular container and it is also well known that it is extremely difficult to obtain the last bit of semi-solid material from the tubular container. This problem is especially well known for tubular containers in the form of tubes of toothpaste. It is an aim of the present invention to obviate or reduce the above mentioned problem.
Accordingly, in one non-limiting embodiment of the invention, there is provided a tubular container for a semi- solid material, which tubular container comprises a neck portion, an opening in the neck portion, a closure member for the opening, a body portion which is for containing the semi-solid material and which is for being squeezed in order to force the semi-solid material through the opening, and a movable member which is positioned in the body portion and which is adapted to be moved along the body portion from a closed end of the body portion towards the opening in the neck portion, the movable member being of such a size relative to the body portion that squeezing of the body portion not only moves the movable member towards the opening but also causes the movable member to force the semi-solid material in front of the movable member, thereby to facilitate the removal of substantially all the semi- solid material from the tubular container.
The semi-solid material may be, for example, toothpaste, hand cream, a pharmaceutical cream, a food spread, glue or any other desired and appropriate semi-solid material.
The tubular container of the present invention will usually include the semi-solid material. If desired however, the tubular container may be manufactured and sold without the semi-solid material.
The movable member may be of any desired and appropriate wedge shape. Thus, for example, the movable member may be long, short, or more oval-shaped, (from a plan view).
The movable member may have a projecting portion for entering into the opening in order to facilitate the removal of substantially all the semi-solid material from the tubular container. The projecting portion may be of such a size as to be a close fit in the opening. The movable member may advantageously be made of a deformable material so that it can deform into the neck portion in order to facilitate the removal of substantially all the semi-solid material from the tubular container. The deformable
material may be a plastics material or a rubber material. The movable member may also be made of a non- deformable solid material if desired.
Apart from the movable member, the tubular container may otherwise be constructed of known shapes and from known materials. Thus, for example, the tubular member may
be constructed from plastics materials or malleable metals.
Usually, the tubular container will be filled from the end of the body portion remote from the opening, this said end then being sealed. Other ways of filling the tubular container may however be employed if desired.
The closure container will usually be a screw cap but it may be a snap cap or any other suitable and appropriate type of closure member.
An embodiment of the invention will now be described solely by way of example and
with reference to the accompanying drawings in which:
Figure 1 is a longitudinal sectional view through a tubular container and shows the tubular container face on; Figure 2 is a longitudinal section of the tubular container shown in Figure 1 but shows the tubular container side on;
Figure 3 is a plan view of the tubular container shown in Figures 1 and 2;
Figure 4 is a longitudinal section similar to that shown in Figure 1 but shows the tubular container in an empty condition; and
Figure 5 is a longitudinal sectional view similar to that shown in figure 2 but again shows the tubular container in an empty condition.
Referring to the drawings, there is shown a tubular container in the form of a toothpaste
tube 2 for a semi- solid material in the form of toothpaste 4. The toothpaste tube 2 comprises a neck portion 6 and an opening 8 in the neck portion 6. The neck portion 6 has an externally threaded portion 10 for receiving a closure member in the form of a screw threaded cap (not shown).
The toothpaste tube 2 has a body portion 12 which is for containing the toothpaste 4 and which is for being squeezed in order to force the toothpaste 4 through the opening 8.
The toothpaste tube 2 also comprises a movable member 14 which is positioned in the body portion 12 and which is adapted to be moved along the body portion 12 from a closed end 16 of the body portion 12 towards the opening 8 in the neck portion 6. As can be seen from the drawings, the movable member 14 is of such a size relative to the cross sectional size of the body portion 12 that squeezing of the body portion 12, for example by the finger 18 and the thumb 20 shown in Figure 2, not only moves the movable member 14 towards the opening 8 but also causes the movable member 14 to force the toothpaste 4 in front of the movable member 14, thereby to facilitate the removal of substantially all the toothpaste 4 from the toothpaste tube 2.
The movable member 14 has a projecting portion 22 for entering into the opening 8 as shown in Figures 4 and 5, in order to facilitate the removal of substantially all the toothpaste 4 from the tubular container. As can be seen from Figures 4 and 5, the projecting portion 22 is of such a size as to be a close fit in the opening 8.
Apart from the presence of the movable member 14, the toothpaste tube 2 can be of known construction and it can be made of known materials. As will be apparent from a comparison of Figures 1 and 2 on the one hand and Figures 4 and 5 on the other hand, the toothpaste tube 2 can be squeezed until such time as the movable member 14 has been moved right up to the opening 8 of the toothpaste tube 2. The squeezed body portion 12 may remain in a squeezed condition as shown in Figure 5 or it may tend to slightly spring back to an open shape, this depending upon the material from which the toothpaste tube 2 is made.After squeezing, the movable member 14 will hold the position to which it has been squeezed, thus ensuring that not only is all the toothpaste 4 squeezed out of the opening 8, but also that protracted squeezing of the body portion 14 is not necessary because all the toothpaste 4 will always be concentrated between the movable member 14 and the opening 8.
It is to be appreciated that the embodiment of the invention described above with reference to the accompanying drawings has been given by way of example only and that modifications may be effected. Thus, for example, the movable member 14 shown in the drawings is wedge shaped from a side view as shown in Figure 5 but other wedge shapes may be employed. Thus, for example, the movable member 14 may be more ovalshaped from a plan view, keeping its basic wedge shape.
Also, the movable member may be made of a deformable material so that the movable member is able to deform into the neck portion and thus ensure that semi-solid material cannot remain in neck portions of complex shapes.
Claims (2)
