Abstract

A longitudinally bisected storage drum (10) includes a pair of hemi-cylindrical drum segments (12, 14) each being formed by a pair of semicircular end panels (12a, 14a, 12b, 14b) which are joined to, and spaced-apart by, a side wall having a hemi-cylindrical wall section (12c, 14c) and a substantially rectangular planar wall section (12d, 14d). The planar wall section of one drum segment defines a longitudinally oriented re-entrant groove (14e) which unites with a longitudinally oriented tongue (12e) protruding from the planar wall section of the other drum segment. Therefore, when the tongue and groove are united with one another, an overall cylindrical drum structure will result. The closely adjacent planar wall sections of each drum segment establish a diametrical parting plane when the tongue and groove are united with one another while the hemi-cylindrical wall segments are provided with longitudinally spaced-apart and outwardly protruding pairs of roll stops (12g, 14g, 12h, 14h) close to this parting plane. Thus, by simply reversing the vertical orientation of bungholes (12j, 14j) formed in each of the upper end panels (e.g., by rolling the drum along its cylindrical side wall until it rests upon the other set of roll stops), the contents within the hemi-cylindrical drum segments can selectively be dispensed by positioning that segment's bunghole in the lower vertical position relative to the other bunghole.

Description

Multi-compartment drum

The present invention relates to the technical field of storage drums. In a preferred embodiment, the present invention allows at least two different materials (e.g., liquids, particulate solid materials, slurries, etc.) to be stored separately from each other in each compartment while being collective (e.g., It is carried out in a storage drum with multiple storage compartments which makes it easy to use as a mixture of materials).

At times, it may be desirable for the end user to use such different materials as a mixture but it may be desirable or necessary to separately supply the injectable materials (eg liquid, particulate material, etc.) to the end user.

Pesticides are preferably applied to the crop as a mixture to enhance application efficacy and / or chemical efficacy. However, it is sometimes impossible to supply such pesticides in a premixed batch at the end user due to the chemical instability of the mixture and / or governmental environmental / occupational safety requirements.

Therefore, it is better to separately accommodate different materials in a common storage drum that cannot be stored in a physically mixed state so that the end user can easily dispense such materials as needed.

Generally, the invention is practiced in longitudinally divided storage drums consisting of a pair of semi-cylindrical drum sections. Thus, each drum portion is formed by a pair of semi-circular end panels joined to and spaced by a side wall having a semi-cylindrical wall portion and a substantially rectangular planar wall portion. Furthermore, the planar wall portion of one drum portion (male drum portion) defines a longitudinally oriented concave groove which is integrated with a longitudinally oriented tongue projecting from the planar wall portion of the other drum portion (female drum portion). Thus, an overall cylindrical drum structure is obtained when the tongue and groove are integrated with each other.

The closely adjacent planar wall portions of each drum portion form a radially divided plane when the tongue and the groove are integrated with each other. The semi-cylindrical wall portion is provided with a pair of roll stops which protrude outwardly and are longitudinally spaced close to the dividing plane. The upper semi-circular end panel is formed with a plug hole, which plug hole is oriented perpendicular to each other when the drum structure is pivoted on its side with respect to the anti-cloud member and the cloud is prevented by a set of anti-cloud members. Formed into a relationship.

Thus, by simply reversing the plug hole in the vertical orientation (ie, rolling the drum along its cylindrical sidewall until the drum seats on another set of anti-rolling members), the plug hole in that portion is opened relative to the other plug hole. By positioning in the lower vertical position, the contents in the semi-cylindrical drum portion can be selectively dispensed.

Other aspects and advantages of the present invention will become more apparent by careful consideration of the detailed description of the preferred exemplary embodiments described below.

1 to 7 show a particularly preferred embodiment of a multiple compartment drum 1 according to the invention. In this connection, the drum 1 essentially comprises separable semi-cylindrical drum parts in the form of a male drum part 12 and a female drum part 14. Each drum portion 12, 14 is joined to and separated by a side wall consisting of semi-cylindrical outer wall portions 12c, 14c and substantially planar inner wall portions 12d, 14d, respectively, by which a pair of semicircular upper and lower panel (12a, 12b, 14a, 14b).

The lower panel 12b, 14b is preferably provided with arc-shaped indentations 12b ', 14b' (or ribs as necessary) for structural strength (see Figure 3). On the other hand, the side wall portions 12c and 14c are preferably provided with indented handles 12c 'and 14c' in order to facilitate handling of the drum 10.

As shown in more detail in FIG. 6, the male drum portion 12 includes a tongue 12e projecting outward from the inner wall portion 12d, while the female drum portion 14 has an inner wall portion 12d. And a concave groove 14e defined by. The tongue 12e and the groove 14e are coherently formed so that a relatively firm interference fit is achieved when integrated. In this regard, it should be noted that the tongue 12e includes an arc shaped head portion 12e 'and a neck 12e of narrower dimensions. Therefore, the head portion 12e 'is coherently fitted into the receiving channel 14e' of the groove 14e, while the inlet 14e of the groove is dimensioned to fit tightly to the neck 12e. . This mutual locking device of the tongue 12e and the groove 14e prevents the drum portions 12, 14 from being easily separated from each other.

However, it should be noted that the longitudinal dimensions of tongue 12e and groove 14e are each smaller than the overall longitudinal dimension of drum 10. Thus, this feature of the invention allows the two parts 12, 14 to be integrated with each other only in the desired orientation, and the coupling of the drum parts in the reverse orientation of that shown in the figure can be prevented.

Although the lower ends of the tongue 12e and the groove 14e are shown in the figure as extending to the end (bottom) wall panels 12b and 14b respectively, they can each end in a similar manner to their upper ends [ie Each may be spaced apart from bottom wall panels 12b and 14b, respectively. However, in the embodiment shown in the figure, the restraining band 16 suitable for the side walls 12c and 14c of the drum portions (circumferential band receiving channels 12f and 16f for storing the reference to Fig. 1 therein (see Fig. 6)). Accordingly, the restraining band 16 serves to prevent relative longitudinal slippage between the drum portions 12 and 14 and is independent of the particular shape of the tongue 12e and the groove 14e. It can be used to improve the structural original state of the drum 10 when the drum parts 12, 14 are integrated with each other.

The closely adjacent planar inner wall portions 12d and 14d form a radially divided plane P (which is shown in the normal direction of the plane of FIG. 5) when the tongue 12e and the groove 14e are integrated with each other. . According to the present invention, the semi-cylindrical wall portions 12c and 14c are each provided with two sets of longitudinally spaced anti-cloud members 12g, 12h; 14g, 14h, respectively. In this regard, each anti-cloud member 12g is located opposite the circumferential direction of each anti-cloud member 14g, while each anti-cloud member 12h is the circumferential direction of each anti-cloud member 14h. It is located on the opposite side. As a result, the anti-rolling members 12g / 14g, 12h / 14h, which are paired in the circumferential direction of the upper and lower portions, have a radial division plane when the drum portions 12, 14 are integrated to form the overall cylindrical drum 10. As shown in FIG. It spans asymmetrically with respect to (P). Preferably, each anti-cloud member 12g, 12h; 14g, 14h defines a convex arc (eg, hemispherical) surface.

Upper end panels 12a and 14a are provided with respective plug holes 12i and 14i (see Fig. 8) and caps 12j and 14j, respectively. Thus, the closure holes 12i and 14i provide access to the interior compartments 12k and 14 (see FIG. 7) of the portions 12 and 14, respectively, so that the compartments 12k and 14k are each large. It is possible to be filled with different injectable materials, allowing each different injectable material contained therein to be dispensed as needed.

As can be seen in the accompanying drawings, the anti-rolling members 12g, 14g; 12h, 14h are symmetrically oriented in the circumferential direction and in the vicinity of the anti-clouding members 12g, 14g; 12h, 14h. By installing the plug holes 12i and 14i in the plugs, the plug holes 12i and 14i are perpendicular to each other when the drum 10 is rolled sideways and seated on the paired anti-cloud members 12g, 14g; 12h, 14h. Can be oriented. Thus, when the drum 10 is seated on the surface S using the set of paired anti-rolling members 12g and 14g shown in Fig. 8, for example, the perpendicular of the plug holes 12i and 14i. The orientation is such that the drum will translate on a distance substantially equal to one-half of the circumferential dimension of the drum 10 (arrow A _{2 in} FIG. 8) to rest on another set of paired anti-cloud members 12h, 14h. It can be reversed by simply rolling the drum 10 along the circumferential side of the drum (arrow A _{1 in} FIG. 8) until Thus, the respective contents in the compartments 12k and 14k can be separately dispensed from the drum 10 through the plug holes 12i and 14i respectively.

While the present invention has been described in connection with what is presently considered to be the most substantial and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments and, conversely, various modifications and equivalents falling within the spirit and scope of the appended claims. It should be understood to include one device.
