Description

[Technical Field]

[0001] The present invention relates to a liquid container that can be suitably used, for example, as a portable beverage container from which liquid can be directly drunk. [Background technology]

[0002] Plastic beverage containers with a drinking spout at the top have a structure consisting of a body and a cap, similar to so-called PET bottles, and are not designed to open wide. For this reason, Patent Document 1 below proposes a beverage container (cup) that can be filled with ice.

[0003] This container has a lower cup with an opening at the top to form a storage space for beverages and ice, and an upper cup that fits over the lower cup and seals the opening. The lower and upper cups are made of transparent plastic, and the upper cup has a bottle opening at its top for drinking or inserting a straw, to which a bottle cap is attached. In other words, it is a configuration in which a PET beverage bottle is detachably divided into two at the top, with the upper cup functioning as a stopper.

[0004] In containers with this configuration, the drinking spout (bottle neck) is made of transparent plastic, giving it a cheap, outdated appearance and the impression of a disposable container. Furthermore, the lower part of the upper cup, i.e., the part that connects to the lower cup, has a larger diameter than the drinking spout and protrudes outward. This part is prone to collisions when carrying or moving, making it easily damaged. Scratches and dents not only deteriorate the appearance, but also impede the connection with the lower cup. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Registered Utility Model No. 3162106 Summary of the Invention [Problem to be solved by the invention]

[0006] The main object of this invention is to eliminate the cheap impression from the drinking spout and to suppress damage to the protruding portion on the periphery so that the bottle can be used repeatedly and comfortably. [Means for solving the problem]

[0007] To this end, the present invention provides the following liquid container.

[0008] In other words, this is a liquid container that has a shoulder member with a cylindrical spout that is smaller in diameter than the container body and can be used as a drinking spout, and the entire shoulder member, including the spout, is made of metal.

[0009] In this configuration, the texture of the metal forming the shoulder member eliminates any cheap impression from the spout, giving the spout a clean and heavy feel, while at the same time providing rigidity to the shoulder member. [Effects of the Invention]

[0010] According to this invention, since the shoulder member, including the spout, is made of metal, even if the other parts of the liquid container are made of synthetic resin, the liquid container does not give off a cheap impression and is suitable for repeated use. Moreover, compared to a container made of synthetic resin, the spout has a cleaner appearance, resulting in a liquid container that can be used repeatedly and comfortably.

[0011] Furthermore, since the shoulder member has rigidity, it is durable and not easily damaged, and as a result, the appearance and the attachability to the container body can be maintained, resulting in a liquid container that can withstand repeated use. [Brief explanation of the drawings]

[Figure 6] FIG. 10 is a half-sectional view of another example of a beverage container. [Figure 7] FIG. 10 is a front view of a cap according to another example. DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the present invention will be described below with reference to the drawings.

[0014] FIG. 1 shows a half-side cross-sectional view of a portable beverage container 11, as an example of a liquid container, filled with liquid L and suitable for direct drinking. This beverage container 11 is small enough to be held in one hand and is composed of three components: a container body 12, a shoulder member 13, and a cap 14, as shown in the exploded perspective view of FIG. 2. The container body 12 and shoulder member 13 form a housing 15 of the beverage container 11, and a cylindrical spout 16 that can be used as a drinking spout is formed at the upper end of the shoulder member 13, which is located at the top of the beverage container 11. The spout 16 has a smaller diameter than the container body 12, extends upward, and is open at its upper end. The opening of the spout 16 can be opened and closed by a cap 14 that is detachably attached to the spout 16.

[0015] The container body 12 is cylindrical with a bottom and made of synthetic resin. An internal fitting tubular portion 21 is formed at the upper end of the container body 12. The internal fitting tubular portion 21 fits inside the lower end portion of the shoulder member 13 so that the shoulder member 13 can be detachably attached. The internal fitting tubular portion 21 is the portion to which the shoulder member 13 is attached by screwing, and is therefore formed in a cylindrical shape. A male thread 22 is formed on the outer peripheral surface of the internal fitting tubular portion 21, and a stepped portion 23 that protrudes outward is formed around the entire circumference of the lower end of the internal fitting tubular portion 21. The outer diameter of this stepped portion 23 corresponds to the outer diameter of the shoulder member 13 to be attached. The portion of the container body 12 below the stepped portion 23 can be any shape other than cylindrical.

[0016] The height of the inner fitting cylindrical portion 21 is set in consideration of the size of the portion below the inner fitting cylindrical portion 21 so as to obtain the desired capacity. Then, at the upper end of the inner fitting cylindrical portion 21, a packing holding portion 26 for holding the packing 25 is formed, as shown in Fig. 3. The packing holding portion 26 has a ridge 26a and a groove 26b formed in this order from top to bottom on the outer circumferential surface of the inner fitting cylindrical portion 21.

[0017] The packing 25 is compressed vertically to provide a seal, and is compressed when the shoulder member 13 is screwed onto the container body 12. It has a main body 25a with an inner and outer double-wall structure attached to the upper end of the inner fitting tubular portion 21, and a pressed-down piece 25b extending diagonally upward toward the outer periphery from the inner peripheral portion of the upper surface of the main body 25a. This pressed-down piece 25b bends when compressed from above, providing a tactile feel when tightened and ensuring good sealing. A fitting edge 25c is formed on the inner peripheral surface of the lower end of the outer wall that constitutes the main body 25a, fitting into the groove 26b of the inner fitting tubular portion 21 to prevent it from coming loose.

[0018] The shoulder member 13 is shaped like an upside-down bowl, with a short cylindrical threaded portion 31 at its lower end. The portion of this threaded portion 31 extending upward from its upper end tapers in diameter toward the center, and the corners 32 are convex curved surfaces. The spout 16 stands upright in the center. The inner peripheral surface of the threaded portion 31 corresponds to the inner fitting cylindrical portion 21 of the container body 12, and is formed with a female thread 33. The outer peripheral surface of the spout 16 is formed with a male thread 34 for threading the cap 14.

[0019] Unlike the container body 12, the shoulder member 13 having such a shape is made of metal and has a double-wall structure consisting of an inner wall member 13a and an outer wall member 13b with an air gap between them. That is, the upper and lower ends of the inner wall member 13a and the outer wall member 13b, which are made of a stainless steel alloy or the like, are joined together by welding to form the shoulder member 13. Therefore, the female thread 33 of the threaded portion 31 is formed in the inner wall member 13a, and the male thread 34 of the spout 16 is formed in the outer wall member 13b. Because the shoulder member 13 has a double-wall structure, even if the female thread 33 is formed in the threaded portion 31, the unevenness of the female thread 33 can be hidden from view.

[0020] A horizontal sealing surface 35 that protrudes inward is formed above the threaded portion 31 on the inner surface of the shoulder member 13. This sealing surface 35 is the portion that abuts against the packing 25 held at the upper end of the container body 12. Between the inner peripheral edge of the sealing surface 35 and the lower end of the inner peripheral surface of the pouring nozzle 16, an inclined surface 36 is formed that forms an outer peripheral surface that is frustum-shaped as a whole.

[0021] A stepped portion 37 that protrudes outward is formed around the entire periphery of the outer peripheral surface of shoulder member 13 below spout 16. The outer diameter of stepped portion 37 corresponds to the outer diameter of cap 14 that is attached to spout 16.

[0022] Such shoulder member 13 may be subjected to appropriate surface treatment such as hairline finishing, painting, or plating, as required.

[0023] The cap 14 has the same structure as a so-called screw cap. That is, it has a closing surface portion 41 located at the upper end and a cylindrical covering tubular portion 42 that extends downward from the outer periphery of the closing surface portion 41 and covers the outer periphery of the spout 16. The closing surface portion 41 and the covering tubular portion 42 are entirely formed of a transparent synthetic resin. Note that "transparent" means that it has the property of transmitting light.

[0024] A removable packing 45 is held on the ceiling surface above the female thread 43 formed on the inner circumferential surface of the covering tubular portion 42. In FIG.

[0025] Fig. 4 shows a perspective view of the beverage container 11 with the three components assembled. (a) is a line drawing, and (b) is an image. The outer surface of the shoulder member 13 in (b) except for the spout 16 has been given a hairline finish, and it can be seen that it has a metallic texture, unlike the synthetic resin container body 12. The metallic texture and luster of the spout 16 can be seen through the transparent cap 14.

[0026] The beverage container 11 configured as described above is carried after a beverage is placed in the container body 15 and the cap 14 is attached. The beverage can be filled into the container body 15 either by removing the shoulder member 13 and filling the container body 15 with the beverage directly, or through the spout 16 of the shoulder member 13. The container body 12 has an internal fitting tubular portion 21, so that a desired amount of beverage can be stored. When adding ice, the shoulder member 13 is removed.

[0027] Shoulder member 13 is a part where the diameter changes from a larger part to a smaller part, and corners 32 of shoulder member 13 are particularly prone to contact when carrying the phone. However, because shoulder member 13 is made of metal, it is rigid and can be surface-treated, such as painted, so the occurrence of scratches and dents can be suppressed.

[0028] When drinking a beverage, the cap 14 is removed and the beverage is drunk or poured directly from the spout 16, but since the spout 16 is also made of metal, it does not give a cheap impression, has a clean and heavy feel, and is suitable as a beverage container that can be washed and reused.

[0029] The metal shoulder member 13 has a different texture than synthetic resin, which makes it more aesthetically pleasing. In particular, the spout 16 visible through the transparent cap 14 has a different appearance from the metallic texture that appears on the outside of the shoulder member 13, which adds variety to the perceived aesthetic, and also contributes to a beautiful impression.

[0030] Furthermore, since the metal shoulder member 13 can be made heavier than the synthetic resin container body 12, it is easy to shake when used as a shaker to mix liquids, for example. This makes it easy to mix the contents well.

[0031] Furthermore, since shoulder member 13 has a double-wall structure with an air layer, condensation is less likely to occur in shoulder member 13. As a result, the entire shoulder member 13, including spout 16, can be kept beautiful, providing a clean feeling when drinking a beverage.

[0032] The packing 25 for achieving a seal between the container body 12 and the shoulder member 13 is held by the container body 12, not by the shoulder member 13, so the shoulder member 13 can be used as a drinking vessel for drinking from the shoulder member 13 with the cap 14 attached. That is, as shown in Figure 5, when the shoulder member 13 is turned upside down, it takes on a shape similar to a sake cup, and since there is no packing on the visible parts or the opening of the shoulder member 13, it can be used as a drinking vessel and drink from it without any discomfort. Moreover, because the shoulder member 13 has weight as mentioned above, it can be placed stably, although this depends on the shape of the top surface of the cap 14.

[0033] The above configuration is one embodiment for carrying out the present invention, and the present invention is not limited to only the above configuration, and other configurations can also be adopted.

[0034] For example, the container body 12 can be made of glass instead of synthetic resin. A double-layered container can also be used as shown in Figure 6. In this case, the occurrence of condensation can also be suppressed in the container body 12.

[0035] The cap 14 can be shaped appropriately from the viewpoint of practicality and aesthetic appeal. For example, as shown in FIG. 7, caps 14 of other shapes may be attached as needed so that they can be selected and used. Of the three caps 14 shown in FIG. 7, the cap 14 on the left side has a hanging ring 14a at the top end that can be used to hang a fingertip or the like. The cap 14 in the center is an example in which the outer surface 14b has a diamond-cut shape. The cap 14 on the right side is an example in which a brim-shaped large diameter portion 14c is formed at the top end.

[0036] Instead of the cap 14, a plug may be provided.

[0037] The shoulder member 13 may be formed without a double wall construction.

[0038] The liquid container may be a liquid storage container or the like, in addition to the beverage container 11 or shaker as described above. [Explanation of symbols]
